Technical field
[0001] The invention relates to the field of bathroom appliances, in particular to an open-close
               type shower door with an automatically closing door closing system, which is mounted
               in a shower room.
 
            Background technology
[0002] At present, when people decorate, a shower room is usually arranged in a toilet,
               and the shower room usually uses a shower door with a glass sheet. The shower door
               comprises an open-close type shower door, and is generally provided with a side frame
               against a wall. The side frame can be made of metal, and the side frame is connected
               with a fixed glass sheet to realize fixed installation of the fixed glass sheet. A
               vertical frame is connected to the other side of the fixed glass sheet, or another
               vertical frame is set against the wall. One side of the movable glass sheet is provided
               with a vertical rotational shaft, and the rotational shaft is generally made of metal.
               In order to realize the rotation of the movable door, a metal rotational shaft on
               the movable door is usually leaned against one side of the fixed glass sheet with
               the vertical frame. A fixed rotational shaft seat is arranged at an upper end and
               a lower end of the vertical frame. The rotational shaft seat is matched with the metal
               rotational shaft. The fixed door and the movable door are connected into a whole,
               and the movable door can rotate around the rotational shaft, so that the movable door
               can be opened and closed. Typically the fixed glass sheet is referred to as a fixed
               door and the shower door comprises at least one movable glass sheet rotatable about
               the fixed glass sheet. Typically the movable glass sheet is referred to as a movable
               door.
 
            [0003] An existing shower door is usually provided with an automatically closing door closing
               system. A common closer is provided, one end of the closer is connected with the movable
               door, and the other end of the closer is connected with a fixed position in the shower
               room, so that the movable door can be automatically closed. One end of the closer
               is fixedly connected with the movable door through a clamping piece, and the other
               end of the closer is rotatably connected with a fixed position. However, in this way,
               generally, the clamping piece connected with the movable door at one end of the closer
               is close to the rotational shaft of the movable door, and the rotating central shaft
               of the rotatable part at the other end is far away from the rotational shaft of the
               movable door, so that the movable door needs more closing force when closing the door,
               and a buffer with a larger size is needed to realize the function of the movable door.
 
            [0004] In addition, when the existing closer is used on shower doors with different shapes,
               different fixed pieces need to be matched, and universality is poor in different installation
               occasions. The existing clamping piece is usually fixed through a lock screw abutting
               against the glass sheet, but when the shower door is opened and closed, the lock screw
               is easy to slip on the glass sheet, so that the automatic closing system fails. The
               existing clamping piece and the main body of the closer are connected by matching
               the lock nut with the countersunk head screw, and when the shower door is mounted
               in a left-right interchange mode, the part needs to be disassembled, so that the connection
               of the part is easy to be loose in use.

            Beneficial effect
[0016] The clamping seat of the switch type shower door is positioned at the far end of
               the rotational shaft of the movable door. The rotational position of the slider of
               the closer is positioned at the near end of the rotational shaft of the movable door,
               and the closing force of the closer required when the movable door is closed is greatly
               reduced, so that the size of the closer can be reduced.
 
            [0017] The invention can be applied to shower doors with different shapes by adopting the
               same parts, or can be applied to shower doors with U-shaped shapes and the like by
               appropriately changing the structure of the individual parts within the protection
               scope of the invention. Meanwhile, the closer can be suitable for installation of
               the same set of shower doors in different directions. The connecting block of the
               clamping seat is fixedly connected with the main body of the closer. The connecting
               block does not need to be disassembled after being connected. The connecting block
               and the main body need to be exchanged up and down when the position of the movable
               door needs to be exchanged left and right, the connecting block and the main body
               are matched and connected with the cavity of the connecting block through a clamping
               plate clamping table which is symmetrical up and down, and the connecting part of
               the connecting block and the main body does not need to be disassembled. The extension
               piece of the fixed seat and the outer end of the sliding body of the closer can also
               be assembled and connected in advance. Disassembly is not needed during installation.
               The extension piece can be inserted into the left-right through hole of the fixed
               piece when the position of the movable door needs to be interchanged left and right.
               Connection failure caused by repeated disassembly and assembly of connection parts
               at two ends of the closer is avoided, and installation appearance and functions are
               not influenced.
 
            [0018] The movable door is clamped by the clamping seat. A through hole or a notch is formed
               in the movable door. The movable door and the clamping plate and the cover plate of
               the clamping seat are connected by the threaded piece, and the problem that the lock
               screw is easy to slide when abutting against the glass movable door is solved.
 
            [0019] The closer is mounted on the top of the movable door and is convenient to mount and
               dismount. The second end of the body and the outer end of the sliding body are connected
               with the clamping seat and the fixed seat through the top nut, the bottom nut and
               the middle stud, so that the closer can freely rotate at a certain angle relative
               to the clamping seat and the fixed seat when moving, and the closer cannot be stuck
               when the sliding piece slides.
