[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a self-care nursing chair, including a nursing chair 1. The nursing chair 1 includes a height-adjustable base 11, a seat 12, a backrest adjustment device 13, a backrest 14, a splicing backrest 15, and a locking component 16. The seat 12 is fixedly connected to the top of the height-adjustable base 11. The seat 12 has two armrests on its front and rear sides. The backrest adjustment device 13 is installed at the bottom of the seat 12. The backrest 14 is fixedly connected to the output end of the backrest adjustment device 13. The splicing backrest 15 is rotatably connected to the top of the backrest 14 through a pivot. The locking component 16 is installed on the inner side of the backrest 14. When in use, this device is adjusted according to the user's height. It can be understood as adjusting the number of splicing backrests 15 according to the length of the user's upper body. When the person sits on the seat 12, the height-adjustable base 11 supports and raises the seat 12, and the back part rests on the backrest 14. The backrest adjustment device 13 can adjust the left and right angles of the backrest 14. Then, the length of the user's upper body is adjusted by controlling the locking component 16 through the remote control button on the seat 12.

[0025] There are eight interlocking backrests 15. The bottom interlocking backrest 15 is rotatably connected to the backrest 14 via a pivot on its bottom left side. Two adjacent interlocking backrests 15 are rotatably connected by pivots. The eight interlocking backrests 15 are separated sequentially from top to bottom, allowing the user's neck to rest on the (n+1)th interlocking backrest 15. At this time, the head can turn to the left and the chin can be raised, making it easier for the doctor to observe. If the head needs to be flat, the interlocking backrest 15 can be reset.

[0026] Locking assembly 16 includes a motor 161, a screw 162, a sleeve 163, a connecting block 164, and a support rod 165. A sliding groove is formed on the inner side of the backrest 14. The motor 161 is fixedly connected to the bottom end of the inner wall of the sliding groove. The output end of the motor 161 is fixedly connected to the screw 162. The sleeve 163 is threadedly connected to the outer side of the screw 162. The locking assembly 16 is adjusted according to the user's upper body length using a remote control button on the seat 12. During adjustment, the motor 161 reverses its rotation, limiting the movement of the sliding groove and the connecting block 164, preventing the sleeve 163 from rotating freely. The motor 161 drives the screw 162 to rotate, and the screw 162, through its connection with the sleeve... The threaded engagement of the tube 163 causes the sleeve 163 to move downwards. As the sleeve 163 moves downwards, it separates from the splicing backrest 15 from top to bottom. After the sleeve 163 separates from the splicing backrest 15, adjacent splicing backrests 15 can rotate relative to each other. A connecting block 164 is fixedly connected to the bottom end of the sleeve 163. A support rod 165 is provided on the rear side of the sleeve 163. The bottom end of the support rod 165 is fixedly connected to the connecting block 164. As the sleeve 163 separates from the splicing backrest 15 from top to bottom, the support rod 165 also separates from the splicing backrest 15. The design of the support rod 165 is to cooperate with the sleeve 163 to improve the support of the splicing backrest 15.

[0027] The outer side of the connecting block 164 is slidably connected to the slide groove. Two positioning grooves are provided on the inner side of each spliced ​​backrest 15, arranged front to back. After the sleeve 163 separates from the spliced ​​backrest 15, adjacent spliced ​​backrests 15 can rotate relative to each other. The spliced ​​backrests 15 are numbered 1, 2, 3…n… from top to bottom, with each spliced ​​backrest 15 representing a separation unit. The sleeve 163 moves downwards by n+1 separation units, causing the nth spliced ​​backrest 15 to separate from the sleeve 163. The nth spliced ​​backrest 15 rotates relative to the n+1th spliced ​​backrest 15. The user's neck rests on the (n+1)th spliced ​​backrest 15, allowing the head to turn to the left and the chin to be raised for easier observation by the doctor. The outer side of the sleeve 163 is slidably connected to the positioning groove at the front end. The sleeve 163 supports the spliced ​​backrest 15 within the positioning groove. After the sleeve 163 moves down by n+1 units, the top block 173 supports the nth spliced ​​backrest 15. The sleeve 163 remains inserted into the positioning groove of the (n+2)th spliced ​​backrest 15, supporting the (n+2)th and the spliced ​​backrest 15 below it. The outer side of the support rod 165 is slidably connected to the positioning groove at the rear end.

[0028] The nursing chair 1 is also equipped with an auxiliary reset assembly 17 for assisting in repositioning. The auxiliary reset assembly 17 includes a bracket 171, a connecting rod 172, and a top block 173. The left end of the connecting block 164 is fixedly connected to the bracket 171, the top end of the bracket 171 is fixedly connected to the connecting rod 172, and the top end of the connecting rod 172 is fixedly connected to the top block 173. A connecting groove is provided on the left side of the backrest 14, and the outer side of the bracket 171 is slidably connected to the connecting groove. The movement trajectory of the top block 173 is linear, while the movement trajectory of the spliced ​​backrest 15 is arc-shaped. The movement trajectory of the spliced ​​backrest 15 intersects with the movement trajectory of the top block 173. The right end of the top block 173 is slidably connected to the spliced ​​backrest 15. If the head needs to be flat, the spliced ​​backrest 15 can be reset. The repositioning of the spliced ​​backrest 15 can be controlled by rotating the motor 161 forward. The operation drives the sleeve 163 upward, which in turn drives the bracket 171 upward. The bracket 171, through the connecting rod 172, drives the top block 173 upward. The bottom of the top block 173 is slightly higher than the top of the sleeve 163, and the top of the top block 173 is lower than the sum of the top of the sleeve 163 and the height of a splicing backrest 15. At this time, the top block 173 pushes the splicing backrest 15 upward to reset it. The splicing backrest 15 rotates to reset, and then the sleeve 163 passes through the splicing backrest 15, resetting the splicing backrest 15 layer by layer from bottom to top, automatically resetting it. The top block 173 is trapezoidal in shape, with a rounded chamfer on the left and right sides of the top ...

[0029] The seat 12 is equipped with a remote control button. The electric height adjustment components inside the height adjustment base 11 are common models. The electric angle adjustment components inside the backrest adjustment device 13 are also common models. The seat 12 can control the height adjustment of the height adjustment base 11, the left and right adjustment of the backrest adjustment device 13, and the forward and reverse stop of the motor 161.

[0030] Working principle: When in use, the device adjusts according to the user's height. This can be understood as adjusting the number of splicing backrests 15 based on the length of the user's upper body. The user sits on the seat 12, and the height adjustment base 11 supports and raises the seat 12. The backrest rests on the backrest 14. The backrest adjustment device 13 can adjust the left and right angles of the backrest 14. Then, according to the length of the user's upper body, the locking component 16 is adjusted by controlling the remote control button on the seat 12. During adjustment, the motor 161 runs in reverse, and the sleeve 163 separates from the splicing backrest 15 from top to bottom, allowing adjacent splicing backrests 15 to rotate relative to each other. The nth splicing backrest 15 rotates to the left, so that the user's neck rests on the (n+1)th splicing backrest 15. At this time, the head can turn to the left, and the chin is raised, making it easier for the doctor to observe.

[0031] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
