Thus, the self-locking and stability of the worm wheel 208 and the worm 209 can prevent the bath chair from accidentally lowering during use to ensure the safety of the user. The cooperation of the sleeve I 202 and the support column 201 provides accurate guidance for the lifting of the screw rod 205, so that the lifting process is stable, and shaking or jamming is avoided.

[0033] Embodiment 2

[0034] In order to adjust the position of the silica gel neck pillow 7 according to the height of the user, as shown in Figure 4 and Figure 5 , the telescopic mechanism 5 includes a sleeve III 501, a clamp ring 502, an inner rod 503, and a nut 504. The sleeve III 501 is fixedly connected to one side of the backrest 4. The clamp ring 502 is fixedly connected to the top of the sleeve III 501. The inner rod 503 is inserted into the top of the clamp ring 502 and extends into the sleeve III 501. The nut 504 is threadedly connected to the outer wall of the inner rod 503. The inner rod 503 is fixedly connected to one side of the connecting plate 6.

[0035] When it is necessary to adjust the position of the silica gel neck pillow 7, first, the nut 504 is screwed to move linearly along the sleeve III 501 to the top. At this time, the binding force of the clamp ring 502 on the inner rod 503 is reduced. Then, according to the height of the user, the inner rod 503 is moved up and down in the sleeve III 501. The inner rod 503 is fixedly connected to the connecting plate 6, thereby driving the connecting plate 6 and the silica gel neck pillow 7 to move up and down.

[0036] After adjusting to the appropriate position, the nut 504 is moved to the bottom. The nut 504 tightly holds the inner rod 503 with the clamp ring 502, so that the inner rod 503 is fixed at the current position. Thus, the position of the silica gel neck pillow 7 can be flexibly adjusted according to the height of different users, providing more fitted and comfortable support for the neck of the user, improving the practical experience, and the structure is relatively simple, while the position of the inner rod 503 can be stably fixed.

[0037] Working principle: When the patient uses it, the lifting mechanism 2 can be operated according to the needs of the user to change the height of the seat surface 3. At the same time, the position of the connecting plate 6 and the silica gel neck pillow 7 is adjusted by the telescopic mechanism 5, so that the silica gel neck pillow 7 better fits the cervical spine part of the user,

[0038] When the user needs to adjust the height of the shower chair, hold the rocker 207 and rotate it, at this time the rotation of the rocker 207 drives the fixedly connected worm 209 to rotate synchronously with the support 210 as the center, at the same time the rotation of the worm 209 drives the worm gear 208 engaged with it to rotate, at this time the screw rod 205 is threadedly connected in the inner wall of the worm gear 208, when the worm gear 208 rotates, the screw rod 205 moves up and down due to the thread cooperation.

[0039] The screw rod 205 drives the lifting plate 204 to move up and down at the same time, and the lifting plate 204 drives the fixedly connected sleeve one 202 to move up and down, so as to realize the lifting of the seat surface 3.

[0040] When the position of the silica gel neck pillow 7 needs to be adjusted, first twist the nut 504 to make the nut 504 linearly move to the top along the sleeve three 501, at this time the binding force of the clamp ring 502 to the inner rod 503 is reduced, then move the inner rod 503 up and down in the sleeve three 501 according to the height of the user, the inner rod 503 is fixedly connected with the connecting plate 6, thereby driving the connecting plate 6 and the silica gel neck pillow 7 to move up and down.

[0041] When the appropriate position is adjusted, move the nut 504 to the bottom, the nut 504 makes the clamp ring 502 tightly hold the inner rod 503, so that the inner rod 503 is fixed at the current position.

[0042] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application makes equivalent replacement or change, should be covered in the protection scope of the present application.
