[0003] Chinese utility model publication number CN215503828U proposes a rehabilitation wheelchair equipped with an anti-misuse protective belt. The wheelchair comprises a wheelchair body, a retractor, a protective belt, a male buckle, and a female buckle. During use, a medical professional extracts the protective belt from the retractor, then passes around the patient sitting in the wheelchair body and engages the male buckle at the end of the protective belt with the female buckle located above the rear surface of the wheelchair body's backrest. The retractor retracts the protective belt against the patient's body surface, and a locking mechanism is operated to prevent further withdrawal of the belt. The retractors are located on the left and right sides of the wheelchair body's backrest, forming a cross-shaped protective structure that wraps around the patient's upper limbs.

[0004] However, the existing technology still has shortcomings:

[0005] The anti-misuse protection belt of the above equipment is fixed on the upper surface of the backrest of the wheelchair body, which is out of reach of the wheelchair user and requires assistance from others to wear it, making it inconvenient for the user to adjust the protection belt.

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-3 As shown, a protective belt for preventing accidental touch for wheelchairs for the elderly comprises an elastic belt 1, elastic rings 2 are symmetrically arranged at both ends of the elastic belt 1, and straps 3 are fixedly installed on the sides of the elastic rings 2. The purpose of the above arrangement is to facilitate the installation of the device on the wheelchair. For a wheelchair with two separately arranged push handles, a pair of elastic rings 2 can be respectively put on the push handles, and then the connection between the device and the wheelchair is reinforced by the straps 3; for a wheelchair with two connected push handles, the elastic belt 1 can be directly put on the push handles, and then the connection between the device and the wheelchair is reinforced by the straps 3; a backrest 4 is fixedly installed on the elastic belt 1, and the backrest 4 is arranged in the middle of a pair of elastic rings 2, a pair of upper protective belts 5 are symmetrically arranged on the upper side of the backrest 4, and a pair of lower protective belts 6 are symmetrically arranged on the lower side of the backrest 4. 5 and the lower protective belt 6 are elastic, which is convenient for providing protection for users of different physiques. One end of the upper protective belt 5 is fixedly connected to the backrest 4, and the other end is fixedly installed with an upper buckle 9. One end of the lower protective belt 6 is fixedly connected to the backrest 4, and the other end is fixedly connected with a lower buckle 10. A limit block 7 is provided between the upper buckle 9 and the lower buckle 10. The upper buckle 9 is fixedly connected to the limit block 7, and the lower buckle 10 is detachably connected to the limit block 7. A baffle 8 is provided on the limit block 7, and the baffle 8 is rotatably connected to the limit block 7. A card block 16 is fixedly provided on the baffle 8, and a card slot 17 is correspondingly opened on the limit block 7. Pushing the baffle 8 can realize the engagement of the card block 16 with the card slot 17, thereby realizing the closure of the baffle 8 and realizing the protection of the locking structure in the limit block 7;

[0023] As an implementation method in this embodiment, the locking structure includes a limiting column 12, a button 14, and a sliding plate 15. A sliding groove 13 is provided in the limiting block 7, and a sliding plate 15 is slidably connected in the sliding groove 13. An elastic member is fixedly installed between the sliding plate 15 and the limiting block 7. A pair of limiting columns 12 are fixedly installed on the sliding plate 15, and a limiting hole 11 is correspondingly provided on the lower buckle 10. The diameter of the limiting column 12 is equal to the inner diameter of the limiting hole 11. A button 14 is fixedly installed on the sliding plate 15. In the natural state, the sliding plate 15 is in contact with the sliding groove under the elastic force of the elastic member. The upper ends of 13 are against each other, and the button 14 is pressed to drive the sliding plate 15 to slide down, thereby driving the limit column 12 to move down, and the lower buckle 10 is inserted into the limit block 7. The button 14 is released, and the sliding plate 15 is reset under the action of elasticity, driving the limit column 12 to reset, so that the limit column 12 is engaged with the limit hole 11, thereby realizing the fixed connection between the lower buckle 10 and the limit block 7. Press the button 14 again and pull out the lower buckle 10 to release the limit of the lower buckle 10 and the limit block 7. The operation is simple. At the same time, the setting of the baffle 8 can prevent the user from accidentally touching it during use.

[0024] Working principle:

[0025] When in use, the device is first fixedly installed on the wheelchair. For a wheelchair with two separately arranged push handles, a pair of elastic rings 2 can be respectively inserted into the push handles, and then the connection between the device and the wheelchair can be reinforced by the straps 3. For a wheelchair with two connected push handles, the elastic band 1 can be directly put on the push handles, and then the connection between the device and the wheelchair can be reinforced by the straps 3. The user sits on the wheelchair, inserts it between the pair of upper protective belts 5, moves the limit block 7 to the chest, opens the baffle 8, presses the button 14 to drive the sliding plate 15 to slide down, thereby driving the limit The column 12 moves downward, and the lower buckle 10 is inserted into the limit block 7. The button 14 is released, and the sliding plate 15 is reset under the action of elasticity, driving the limit column 12 to reset, so that the limit column 12 is engaged with the limit hole 11, thereby realizing the fixed connection between the lower buckle 10 and the limit block 7. Closing the baffle 8 can protect the user and the locking structure inside the 7. When it is necessary to release the restriction of the device, open the baffle 8, press the button 14, and pull out the lower buckle 10 to release the restriction of the lower buckle 10 and the limit block 7.
