[0003] The existing backrests for the elderly do not have adjustable armrest angles, which cannot meet the needs of users and have low practicality. Furthermore, people of different heights have different requirements for armrest height, and the existing backrests for the elderly do not allow for armrest height adjustment. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable backrest for the elderly, solving the problems that the armrest angle and armrest height cannot be adjusted.

[0005] To achieve the above objectives, an adjustable backrest for the elderly is provided, comprising: a lower support frame and a backrest frame. Adjustment plates are fixedly connected to both sides of the backrest frame. Multiple adjustment holes and insertion holes are provided on the sides of both adjustment plates. Mounting base plates are attached to the sides of both adjustment plates. Mounting plates are fixedly connected to the lower surfaces of both mounting base plates. Adjustment bolts are rotatably connected inside both mounting plates. Rotating rings are fixedly connected to the outside of both adjustment bolts. The outer surface of the rotating rings is rotatably connected to the inside of the mounting plates. Insertion rods are fixedly connected to the sides of both mounting plates. One end of the insertion rod is inserted into the insertion hole, and one end of the adjustment bolt is threaded into the adjustment hole, facilitating adjustment of the armrest height as needed and increasing the practicality of the device.

[0006] Both mounting base plates are rotatably connected to rotating columns inside, and both rotating columns are fixedly connected to adjusting rings outside. Multiple limiting holes are opened on the upper surface of the adjusting rings. Both mounting base plates are threadedly connected to limiting bolts inside, and both limiting bolts are fixedly connected to insert pins at their upper ends. The upper ends of the insert pins are inserted into the limiting holes to facilitate adjustment of the handrail angle and provide a comfortable user experience.

[0007] According to the aforementioned adjustable backrest for the elderly, the insert rod is a square column, the insertion hole is a square hole, and the longitudinal cross-sectional area of ​​the insert rod and the insertion hole are the same, which facilitates the installation of the auxiliary mounting base.

[0008] According to the aforementioned adjustable backrest for the elderly, multiple limiting holes are arranged in a ring, and the armrest is fixedly connected to the side of the rotating column. The limiting holes facilitate the fixing of the adjusted armrest.

[0009] According to the aforementioned adjustable backrest for the elderly, two sets of limiting teeth are fixedly connected to the upper surface of the lower support frame. The two sets of limiting teeth are symmetrically arranged to facilitate the limiting of the adjustment frame.

[0010] According to the aforementioned adjustable backrest for the elderly, the two ends of the lower support frame are rotatably connected to the two ends of the backrest frame, and the side of the backrest frame is rotatably connected to an adjustment frame, which facilitates support of the backrest frame.

[0011] According to the aforementioned adjustable backrest for the elderly, an elastic backrest is fitted outside the support frame, and a seat cushion is fixedly connected to the lower surface of the elastic backrest to facilitate the elderly to lean against it.

[0012] According to the aforementioned adjustable backrest for the elderly, the longitudinal section of the rotating column is T-shaped.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. Insert the plug rod into the plug hole to facilitate the installation of the auxiliary mounting base. Rotate the adjusting bolt to install it into the adjusting hole. Rotate the ring to allow the adjusting bolt to rotate inside the mounting plate, making it easy to adjust the handrail height as needed and increasing the practicality of the device.

[0015] 2. By rotating the limiting bolt, the insert can be easily inserted into the limiting hole on the adjusting ring, making it easy to adjust the angle of the handrail and providing a comfortable user experience.

Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model provides an adjustable backrest for the elderly, comprising: a lower support frame 1 and a backrest frame 7. Adjustment plates 5 are fixedly connected to both sides of the backrest frame 7. Multiple adjustment holes 4 and insertion holes 18 are provided on the sides of the two adjustment plates 5 for the installation of adjustment bolts 12 and the insertion of insertion rods 17. Mounting base plates 16 are attached to the sides of the two adjustment plates 5. Mounting plates 11 are fixedly connected to the lower surfaces of the two mounting base plates 16. Adjustment bolts 12 are rotatably connected inside the two mounting plates 11 for fixing. Rotating rings 13 are fixedly connected to the outside of the two adjustment bolts 12. The outer surface of the rotating rings 13 is rotatably connected to the inside of the mounting plates 11. Insertion rods 17 are fixedly connected to the sides of the two mounting plates 11 for assisting the installation of the mounting base plates 16. One end of the insertion rod 17 is inserted into the insertion hole 18, and one end of the adjustment bolt 12 is threaded into the adjustment hole 4.

[0026] Both mounting base plates 16 are rotatably connected to rotating columns 9 inside, and both rotating columns 9 are fixedly connected to adjusting rings 10 outside. Multiple limiting holes are opened on the upper surface of the adjusting rings 10. Both mounting base plates 16 are threadedly connected to limiting bolts 14 inside, which are used to drive the insertion post 15 to move up and down. The upper ends of both limiting bolts 14 are fixedly connected to the insertion post 15, which is used to insert into the limiting holes on the adjusting rings 10. The upper end of the insertion post 15 is inserted into the limiting hole.

[0027] The insertion rod 17 is a square post, and the insertion hole 18 is a square hole. The longitudinal cross-sectional areas of the insertion rod 17 and the insertion hole 18 are the same. By inserting the square insertion rod 17 into the insertion hole 18, the mounting base plate 16 can be installed horizontally.

[0028] Multiple limiting holes are arranged in a ring, and the side of the rotating column 9 is fixedly connected to the handrail 19, which facilitates arm placement.

[0029] Two sets of limiting teeth 3 are fixedly connected to the upper surface of the lower support frame 1. The two sets of limiting teeth 3 are symmetrically arranged, and the adjusting frame 2 can be limited by the limiting teeth 3.
