Below is the description of the invention through the specific embodiments:

As shown in Figs. 1 and 2, a bathtub heat insulation cover which is pulled up and down by a wire rope comprises a heat insulation cover body 1 arranged horizontally and transversely, wherein a left lifting crossbar 21 arranged horizontally and transversely and extending in a front-and-rear direction is arranged on a left end of an upper surface of the heat insulation cover body 1, a right lifting crossbar 21 which is arranged horizontally and transversely and extending in the front-and-rear direction is arranged on a right end of the upper surface of the heat insulation cover body 1, the left lifting crossbar 21 is fitted with a left lifter 31, and the right lifting crossbar 22 is fitted with a right lifter 32.

Furthermore, the left lifter 31 comprises a left front vertical post 311 which is arranged on a front end of the left lifting crossbar 21 and arranged vertically and a left rear vertical post 312 which is arranged on a rear end of the left lifting crossbar 21 and arranged vertically. Left guide grooves 313 which extend vertically are respectively formed on the left front vertical post 311 and the left rear vertical post 312, and a front end and a rear end of the left lifting crossbar 21 are respectively inserted in the left guides 313 at the corresponding side in an embedding manner. The right lifter 32 comprises a right front vertical post 321 which is arranged on a front end of the right lifting crossbar 22 and arranged vertically and a right rear vertical post 322 which is arranged on a rear end of the right lifting crossbar 22 and arranged vertically; right guide grooves 323 which extend vertically are respectively formed on the right front vertical post 321 and the right rear vertical post 322, and a front end and a rear end of the right lifting crossbar 22 are respectively inserted in the right guides 323 at the corresponding side in an embedding manner.

Moreover, a middle crossbar 4 which is arranged horizontally and transversely and extends in a left-and-right direction is arranged between the left lifter 31 and the right lifter 32, the middle crossbar 4 is provided with a lifting driving motor 5, and a left drive pulley 61 and a right drive pulley 62 which move in reverse directions synchronously are arranged beside the middle crossbar 4; the lifting driving motor 5 is respectively connected with the left drive pulley 61 and the right drive pulley 62 in the driving way; a left driving wire rope 71 is coiled on the left drive pulley 61, and both ends of the left driving wire rope 71 are respectively connected with both ends of the left lifting crossbar; and a right driving wire rope 72 is coiled on the right drive pulley 62, and both ends of the right driving wire rope 72 are respectively connected with both ends of the right lifting crossbar 22.

Wherein, the middle crossbar 4 is provided with a chain transmission mechanism which is driven by the lifting driving motor 5, and the left drive pulley 61 and the right drive pulley 62 are respectively connected with the chain of the chain transmission mechanism; or the middle crossbar 4 is provided with a belt transmission mechanism which is driven by the lifting driving motor 5, and the left drive pulley 61 and the right drive pulley 62 are respectively connected with the belt of the belt transmission mechanism.

During the use of the bathtub heat insulation cover, when a user wants to open the heat insulation cover body 1, the lifting driving motor 5 drives the left drive pulley 61 to move to the right and drive the right drive pulley 62 to move to the left through the chain transmission mechanism or the belt transmission mechanism; the left drive pulley 61 which moves to the right pulls the left driving wire rope 71 to move to the left, and the left lifting crossbar 21 is pulled by the left driving wire rope 71 to move up along the left guide 313. During the process, the right drive pulley 62 which moves to the left pulls the right driving wire rope 72 to move to the left, and the right lifting crossbar 22 is pulled by the right driving wire rope 72 to move up along the right guide 323; at this time, the left lifting crossbar 21 and the right lifting crossbar 22 move up synchronously, and the left lifting crossbar 21 and the right lifting crossbar 22 drive the heat insulation cover body 1 to move up, so as to open the heat insulation cover body 1.When the user wants to re-cover the heat insulation cover body 1, the lifting driving motor 5 rotates reversely, the left drive pulley 61 moves to the left and the right drive pulley 62 moves to the right. During the process, the left driving wire rope 71 releases the left lifting crossbar 21 and allows the left lifting crossbar 21 to move down, and the right driving wire rope 72 releases the right lifting crossbar 22 and allows the right lifting crossbar 22 to move down; the left lifting crossbar 21 and the right lifting crossbar 22 which move synchronously drive the heat insulation cover body 1 to move down, and finally the heat insulation cover body 1 is covered on the bathtub100.

It should be further explained that guide grooves are respectively formed on inner sides (the sides close to the bathtub100) of the respective vertical posts of the left lifter and the right lifter, and the guide grooves play a role of fixing moving directions of the lifting crossbars, so that the heat insulation cover body 1 does not shake greatly; wherein, the wire rope may be hidden within the guide groove at the corresponding side, so as to satisfy the protecting and pleasing needs.

It should be further noted that a direct current motor is adopted for the lifting driving motor 5 in Embodiment 1, wherein the lifting driving motor 5 may control the forward and reverse rotation through a control switch or through a remote control. Wherein, the left lifter 31 or the right lifter 32 is provided with a travel switch, i.e. in Embodiment 1, lifting and stopping positions of the heat insulation cover body 1 may be set through the travel switch.

Wherein, in addition to the bathtubs 100, the bathtub heat insulation cover may be applied to small swimming pools.

To sum up, with the structural design, the bathtub heat insulation cover has the advantages of novel design, high degree of automation and convenience in use.
