In the description of this embodiment, orientations or position relations indicated by terms such as "upper", "lower", "left", and "right" are based on the drawings. These orientations or position relations are intended only to facilitate description and simplify operation and not to indicate or imply that a device or element referred to must have such particular orientations or must be configured or operated in such particular orientations. Thus, these orientations or position relations are not to be construed as limiting the present application.

In addition, terms such as "first" and "second" are only used for distinguishing between descriptions and have no special meanings.

Referring to FIGS. 3 to 9, this example provides an elevating pivot shower door, and the elevating pivot shower door includes a first slide rail profile 10, a second slide rail profile 20, an elevating cylinder 30, and a pivot sliding door 40. The first slide rail profile 10 is arranged vertically, a first cavity 11 is provided in the first slide rail profile 10, each of an upper end, a lower end, and a side of the first cavity 11 is provided with an opening, and a cylinder fixing member 50 is disposed at an opening of the lower end of the first cavity 11. A protrusion portion 21 embedded into the first cavity 11 is provided on the second slide rail profile 20, the inside of the protrusion portion 21 is hollow to form a second cavity 22, a cylinder limit member 60 is disposed in the second cavity 22, and pivot limit members 70 are disposed at the upper end of the second slide rail profile 20 and the lower end of the second slide rail profile 20, respectively. The elevating cylinder 30 is disposed in the second cavity 22, an output rod 31 of the elevating cylinder 30 is connected to the cylinder fixing member 50, a cylinder body of the elevating cylinder 30 abuts against the cylinder limit member 60, and the elevating cylinder 30 is used for driving the second slide rail profile 20 to move up and down relative to the first slide rail profile 10. A sliding-door pivot profile 41 is disposed on a side of the pivot sliding door 40, and two ends of the sliding-door pivot profile 41 are rotatably connected to the two pivot limit members 70 correspondingly such that the pivot sliding door 40 is rotatable relative to the second slide rail profile 20.

Thus, the pivot sliding door 40 has an elevating function so that the pivot sliding door 40 can effectively avoid a shower valve and the like and can open 180° without obstruction. The pivot sliding door 40 can not only fulfill the function of blocking shower water during a shower but also open perfectly close to a wall when not in use, maximizing space utilization. In addition, the overall structure is compact, and the shape is beautiful.

The cylinder limit member 60 is fixed to the second slide rail profile 20 through a bolt, and the position of the cylinder limit member 60 in the second cavity 22 is calculated according to the motion stroke of the elevating cylinder 30. The cylinder fixing member 50 is fixed to the bottom of the first slide rail profile 10 through a bolt, and an insertion hole is provided on the cylinder fixing member 50, where the output rod 31 of the elevating cylinder 30 is inserted into the insertion hole.

Optionally, as shown in FIGS. 3 to 5, a limit protrusion 12 is provided at a side of the first slide rail profile 10 provided with an opening, multiple first limit plastic members 80 and anti-displacement sleeves 90 correspondingly abutting against the multiple first limit plastic members 80 are vertically disposed on the limit protrusion 12, first grooves 23 are provided at positions on the second slide rail profile 20 that correspond to positions where the multiple first limit plastic members 80 are mounted, and the multiple first limit plastic members 80 are in interference fit with the first grooves 23, respectively.

Protrusions for increasing friction are provided on the outer surfaces of the first limit plastic members 80 here. Only the protrusions are in close contact with the first groove 23 to prevent the pivot sliding door 40 from coming down and affecting the elevating function. The anti-displacement sleeves 90 are used for limiting the vertical movements of the first limit plastic members 80. In addition, the anti-displacement sleeves 90 have slightly smaller sizes than the first limit plastic members 80, forming a gap with the first groove 23 to reduce frictional resistance and improve elevating smoothness.

Optionally, as shown in FIGS. 3 and 6, multiple second limit plastic members 100 are vertically disposed on the outer surface of the protrusion portion 21, second grooves 13 are provided at positions on an inner wall of the first cavity 11 that correspond to positions where the multiple second limit plastic members 100 are mounted, and the multiple second limit plastic members 100 are in interference fit with the second grooves 13, respectively.

The structure of each of the second limit plastic members 100 here is similar to the structure of each of the first limit plastic members 80, and the second limit plastic members 100 are also used for preventing the pivot sliding door 40 from coming down. In addition, the second limit plastic members 100 are connected and fixed to the second slide rail profile 20 through bolts.

Optionally, each of the pivot limit members 70 is provided with a boss 71 inserted into an end portion of the second cavity 22 and a pivot cavity 72 rotatably connected to an end portion of the sliding-door pivot profile 41, thereby ensuring that the pivot sliding door 40 and the second slide rail profile 20 are reliably mounted.

As shown in FIG. 7, an avoidance hole 75 for the output rod 31 of the elevating cylinder 30 to pass through is provided in a boss 71 of a pivot limit member 70 located at the lower end of the second slide rail profile 20, and an avoidance step 73 for avoiding the cylinder fixing member 50 is provided on the boss 71.

Optionally, as shown in FIGS. 3, 6, and 7, waterproof strips 110 disposed on the second slide rail profile 20 extend to two sides of the sliding-door pivot profile 41, and a pivot limit member 70 located at the lower end of the second slide rail profile 20 is provided with water guiding slots 74 located at positions corresponding to positions where the waterproof strips 110 are mounted.

The waterproof strips 110 closely abut against the sliding-door pivot profile 41 so that shower water can be effectively prevented from splashing from the sliding-door pivot profile 41. On the one hand, the water guiding slots 74 assist in mounting the waterproof strips 110, and on the other hand, the water guiding slots 74 can prevent a water flow from flowing to the outer side of the pivot sliding door 40 through a flat surface of the pivot limit member 70 during a shower.

Optionally, a silent pad 120 is disposed on the lower surface of a pivot limit member 70 located at the lower end of the second slide rail profile 20.

The silent pad 120 here snaps into the pivot limit member 70, which can prevent the pivot limit member 70 from a collision and damage during a downward movement and reduce contact noise.

Optionally, as shown in FIG. 8, a dust-blocking cover plate 130 configured to expose only a port of the upper end of the first cavity 11 is disposed at an upper end of the first slide rail profile 10, and a limit piece 140 is detachably disposed on the dust-blocking cover plate 130.

When the limit piece 140 is mounted on the dust-blocking cover plate 130, the limit piece 140 serves as an upper limit stop for a pivot limit member 70 located at the upper end of the second slide rail profile 20 such that the pivot sliding door 40 is not capable of being elevated. When the limit piece 140 is removed, the limit piece 140 does not function to limit the pivot limit member 70, and the pivot sliding door 40 is capable of being freely elevated.

Additionally, after the assembly of the elevating cylinder 30 is completed, the self-weight of the pivot sliding door 40 is not applied in packaging and transportation processes, which may cause the second slide rail profile 20 to automatically move up and down relative to the first slide rail profile 10. The limit piece 140 serves to prevent the second slide rail profile 20 from automatically moving up and down. After the pivot sliding door 40 is assembled in a shower enclosure, the limit piece 140 may be detached, and the elevating function is restored.

Optionally, a water-blocking and sound-dampening strip 150 is disposed at the lower edge of the pivot sliding door 40 for effective waterproofing and soundproofing during a shower.

Optionally, as shown in FIGS. 3 and 9, the elevating pivot shower door further includes a wall-mounted profile 160, where the wall-mounted profile 160 is configured to be fixed onto a wall, the first slide rail profile 10 is embedded in the wall-mounted profile 160, a screw fixed to the first slide rail profile 10 is screwed into a side surface of the wall-mounted profile 160, and a cover plate profile 170 for concealing the screw snaps onto the wall-mounted profile 160.

5. 5. The elevating cylinder 30 is inserted into the second cavity 22 of the second slide rail profile 20 from the bottom, the output rod 31 of the elevating cylinder 30 is inserted through the avoidance hole 75 of the lower pivot limit member 70, the lower pivot limit member 70 is connected and fixed to the lower end of the second slide rail profile 20 through a bolt, the output rod 31 of the elevating cylinder 30 is inserted into the insertion hole of the cylinder fixing member 50, and the cylinder fixing member 50 is mounted in the first cavity 11 of the first slide rail profile 10 and is tightened and fixed through the bolt.
6. 6. Pivot plastic members at two ends of the sliding-door pivot profile 41 of the pivot sliding door 40 are placed into the pivot cavities 72 of the upper pivot limit member 70 and the lower pivot limit member 70, and the upper pivot limit member 70 is inserted into the upper end of the second slide rail profile 20 and is connected and fixed through a bolt.
7. 7. The silent pad 120 is fixed to the bottom of the lower pivot limit member 70 to enhance the sound reduction effect and prevent damage to a surface of a bathtub caused by direct contact with the bathtub.
8. 8. The dust-blocking cover plate 130 is inserted into the upper end of the first slide rail profile 10 and is connected and fixed to the first slide rail profile 10 through a bolt, and the limit piece 140 is then connected and fixed to the dust-blocking cover plate 130 through the bolt.
