[0024] Example 1: As Figures 1 to 6 As shown, this embodiment provides a rotatable shower chair, including a support leg assembly 1, a seat assembly 2, and a needle roller rotating assembly 3. The seat assembly 2 is mounted on the support leg assembly 1 via the needle roller rotating assembly 3, and the seat assembly 2 can rotate relative to the support leg assembly 1 via the needle roller rotating assembly 3. The needle roller rotating assembly 3 includes at least a base 31, a top plate 32, and a plurality of needle rollers 33. The base 31 is fixed to the support leg assembly 1, the seat assembly 2 is fixed to the bottom of the seat assembly 2, and the plurality of needle rollers 33 are circumferentially spaced between the base 31 and the top plate 32.

[0025] This embodiment provides a rotatable shower chair, wherein the rotatable connection between the seat assembly and the support leg assembly is stable and reliable.

[0026] Specifically, by adopting the needle roller rotating assembly 3 provided in this embodiment, its structure is simple, which can make the rotation of the seat assembly 2 relative to the support foot assembly 1 more stable, effectively reduce the shaking of the seat assembly 2, thereby improving the reliability of the overall product structure and reducing the failure rate.

[0027] In this embodiment, the chassis 31 is fixed to the support leg assembly 1, and a retainer 34 is fixedly provided on the top surface of the chassis 31. A plurality of mounting grooves 340 are provided on the retainer 34 at intervals along the circumference. Each mounting groove 340 extends in the radial direction. The needle roller 33 is rotatably installed in the mounting groove 340. Its structure is simple and its design is reasonable, which can ensure the stability and reliability of the installation of the needle roller 33, thereby achieving the purpose of ensuring the stability and reliability of the seat assembly 2.

[0028] Furthermore, the retainer 34 is annular in shape, including an outer ring portion 341 and an inner ring portion 342. A plurality of reinforcing ribs 343 are connected between the outer ring portion 341 and the inner ring portion 342 at intervals along the circumference. The mounting groove 340 is provided on the outer ring portion 341. Its structure is simple, thereby improving the stability and reliability of the overall structure of the retainer 34.

[0029] Furthermore, the top plate 32 is fixed to the bottom of the seat assembly 2, and the top plate 32 abuts against the needle roller 33. A central shaft 35 is provided through the center of the base plate 31, the inner ring portion 342 and the top plate 32. The top plate 32 can rotate on the needle roller 33 around the central shaft 35. Its structure is simple and its design is reasonable, which can make the rotation of the seat assembly 2 relative to the support foot assembly 1 more stable and effectively reduce the shaking of the seat assembly 2.

[0030] In this embodiment, a locking mechanism 4 is also included. The locking mechanism 4 is disposed at the bottom of the seat assembly 2. The locking mechanism 4 can fix the top plate 32 relative to the chassis 31. Its structure is simple and its design is reasonable. When it is necessary to rotate the seat assembly 2, the locking mechanism 4 is used to release the top plate 32 relative to the chassis 31, and the seat assembly 2 can then rotate. When it is necessary to fix the seat assembly 2, the locking mechanism 4 is used to fix the top plate 32 relative to the chassis 31, and the seat assembly 2 is fixed and cannot be rotated, thereby ensuring the safety of the passenger.

[0031] Furthermore, the locking mechanism 4 includes at least a mounting bracket 41, a spring 42, a pin 43, and an operating member 44. A first through hole 320 is provided on the top plate 32, and a plurality of second through holes 310 are provided on the bottom plate 31 at circumferential intervals. The mounting bracket 41 is located above the first through hole 320 and on the top plate 32. The pin 43 is located below the mounting bracket 41 and is used to insert into the first through hole 320 and the second through holes 310. The spring 42 is pressed between the mounting bracket 41 and the pin 43. The operating member 44 is connected to the pin 43 and is used to drive the pin 43 to move upward, at least disengaging the lower part of the pin 43 from the second through hole 310. The locking mechanism 4 has a simple structure, is easy to operate, and has high stability and reliability.

[0032] When it is necessary to rotate the seat assembly 2, press the operating member 44 to make the pin 43 move upward against the spring force of the spring 42, thereby causing the lower part of the pin 43 to disengage from the second through hole 310. At this time, the top plate 32 is released relative to the bottom plate 31, and the seat assembly 2 can be rotated.

[0033] When the seat assembly 2 is rotated to the appropriate position and needs to be fixed, the operating part 44 is released. Under the spring force of the spring 42, the pin 43 moves downward and the lower end of the pin 43 is inserted into the corresponding first through hole 320 and second through hole 310. At this time, the top plate 32 is fixed relative to the chassis 31, and the seat assembly 2 is fixed and cannot be rotated, ensuring the safety of the passenger.

[0034] In this embodiment, the operating component 44 includes at least a rotating part 441, a connecting part 442 located at the inner end of the rotating part 441, and a pressing part 443 located at the outer end of the rotating part 441. The rotating part 441 is rotatably connected to the connecting bracket 5 located at the bottom of the seat assembly 2. The connecting part 442 is connected to the pin 43. Its locking mechanism 4 has a simple structure, is easy to operate, and has high stability and reliability. Specifically, by pressing the pressing part 443 downward, due to the lever principle, the connecting part 442 moves upward, causing the pin 43 to move upward against the spring force of the spring 42, causing the lower part of the pin 43 to disengage from the second through hole 310. When the pressing part 443 is released, under the action of the spring force of the spring 42, the pin 43 moves downward, and the lower end of the pin 43 is inserted into the corresponding first through hole 320 and second through hole 310. At this time, the top plate 32 is fixed relative to the base plate 31.

[0035] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
