[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] Example:

[0038] like Figure 1-3 As shown, in this embodiment, a column type lifting cover device for a bathtub is provided, and the column type lifting cover device arranged around the bathtub 1 includes:

[0039] Top cover assembly 2, lifting column assembly 3, synchronization assembly 4 and driving device 5;

[0040] The top cover assembly 2 is arranged on the top of the lifting column assembly 3;

[0041] In this embodiment, there are four lifting column assemblies 3 evenly distributed around the bathtub 1. The lifting column assembly 3 includes a plurality of lifting cylinders with diameters from large to small, and the lifting cylinder with a large diameter can be sleeved outside the lifting cylinder with a small diameter. The lifting cylinder with the largest diameter is located at the top of the lifting column assembly 3, and adjacent lifting cylinders are threadedly matched.

[0042] The driving device 5 is linked with the synchronization component 4 to realize the lifting movement of the four lifting column components 3 of this embodiment.

[0043] The lifting column assembly 3 of the present application is composed of multiple lifting cylinders, and the lifting cylinder with the largest diameter is located at the top of the lifting column assembly 3. Because the diameters of the lifting cylinders arranged from top to bottom are from large to small, the diameter of the lifting column assembly 3 is a structure with a large top and a small bottom. In this way, when used outdoors, rainwater will not enter the gaps between adjacent lifting cylinders, reducing rainwater residue, avoiding the problem of waterproof sealing, and improving the service life.

[0044] In this embodiment, the synchronous assembly 4 includes a synchronous belt 401 and four synchronous wheels 402 . Each synchronous wheel 402 is connected to the lifting column at the top of the lifting column assembly 3 . The synchronous belt 401 is wound around the four synchronous wheels 402 .

[0045] The top cover assembly 2 includes a frame 201 and a top cover body 202 . The frame 201 is connected to the lifting column assembly 3 . The synchronization assembly 4 and the driving device are arranged in the frame 201 . The driving device in this embodiment is a driving motor.

[0046] In the above structure, the four lifting column assemblies 3 are coordinated by a driving device through a synchronous belt 401 and four synchronous wheels 402 to achieve lifting motion. The synchronous belt 401 of the closed-loop structure does not need an electrical synchronizer, so as to avoid direct damage to the lifting column assembly 3 due to a failure in the electrical appliance, or even chain damage to other parts in serious cases. At the same time, the synchronous belt 401, the synchronous wheel 402 and the driving motor are arranged in the frame 201 and covered by the top cover 202, so as to avoid the problem that the synchronous assembly 4 and the driving device are exposed and easily damaged.

[0047] The specific lifting column assembly 3 structure of this embodiment also includes a locking assembly arranged in the lifting column, and the locking assembly includes a locking rod and a locking seat 306;

[0048] The locking rod is connected to the lifting cylinder column with the largest diameter of the lifting cylinder assembly 3 , and the locking seat 306 is connected to the lifting cylinder column with the smallest diameter of the lifting cylinder assembly 3 .

[0049] Specifically, the lifting column includes a first lifting column 301, a second lifting column 302 and a third lifting column 303 from top to bottom and with diameters from large to small. The diameter of the first lifting column 301 is larger than the diameter of the second lifting column 302, and the diameter of the second lifting column 302 is larger than the diameter of the third lifting column 303.

[0050] The locking rod includes a locking member 304 and a locking sleeve 305. The locking sleeve 305 is sleeved on the locking member 304. The top of the locking member 304 is connected to the synchronous wheel 402. The top of the locking sleeve 305 is connected to the first lifting cylinder column 301.

[0051] The locking seat 306 is provided with a locking portion 307 that can cooperate with the locking member 304 .

[0052] The movement principle of the lifting column assembly 3 of this embodiment is as follows:

[0053] The descending process of the lifting column assembly 3: the synchronous wheel 402 drives the locking piece 304 to rotate, thereby driving the first lifting column 301 to rotate through the locking sleeve 305. Because the first lifting column 301 and the second lifting column 302 are threadedly matched, the first lifting column 301 moves relative to the second lifting column 302. When the locking sleeve 305 cooperates with the locking seat 306, the first lifting column 301 drives the second lifting column 302 to rotate together, and the second lifting column moves relative to the third lifting column 303. When the locking piece 304 cooperates with the locking part 307 on the locking seat 306, the descending process of the lifting column assembly 3 is completed.

[0054] During the ascending process of the lifting column assembly 3, it is only necessary to rotate the synchronous wheel 402 in the opposite direction.

[0055] Combined with the structure of the synchronization assembly 4 of this embodiment, when the driving device acts on one of the synchronization wheels 402 to rotate, the synchronization wheel 402 will rotate together with the other synchronization wheels 402 through the synchronization belt 401, so that the four lifting column assemblies 3 of this embodiment can be lifted and lowered together.

[0056] The cross section of the locking member 304 of this embodiment is a regular polygon, and the locking portion 307 is a groove structure matched with the locking member 304 .

[0057] In this embodiment, a disc-shaped base 308 is provided at the bottom of the third lifting cylinder column 303, so that the entire lifting column assembly 3 can be more stably placed on the ground.

[0058] In summary, the diameter of the lifting column assembly 3 of the present application is a structure that is larger at the top and smaller at the bottom. In this way, when used outdoors, rainwater will not enter the gaps between adjacent lifting columns, reducing rainwater residue, avoiding the problem of waterproof sealing, and improving service life. At the same time, the synchronization assembly 4 and the drive device are built-in structures, avoiding the problem of the synchronization assembly 4 and the drive device being exposed and easily damaged.

[0059] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
