[0002] A wheelchair is a chair with wheels that can help replace walking. It is divided into electric and manual folding wheelchairs. It is an important means of transportation for the wounded, sick, and disabled to recover at home, transport, see a doctor, and go out for activities. In order to ensure that the wheelchair users have more comfortable using conditions, wheelchairs are usually equipped with armrests for placing the arms.
[0003] Although the existing armrests can provide arm placement, for hemiplegic patients, since the wheelchair armrests are relatively narrow, the hemiplegic patients' hands are in a clenched fist state, and the shoulder joints are drooping. Because the muscle strength is weakened and unable to support, the hemiplegic hands are very easy to slip off the armrests. The drooping hemiplegic hands can easily cause shoulder dislocation, hand edema and other problems, causing secondary injuries and increasing the patient's pain. In view of this, we propose a detachable hand rest for wheelchairs to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0018] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this description, those skilled in the art can make creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
[0019] The utility model discloses a detachable hand rest for a wheelchair, which solves the technical problems in the prior art. The overall idea is as follows:
[0020] Embodiment 1:
[0021] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A detachable hand rest for a wheelchair, comprising: a connecting sleeve 1, a slot 101, a positioning assembly, a hand rest plate 2, an arc groove 201, a slot 203, a positioning groove 204, a connecting sheet 3 and a dividing strip 301, wherein the slot 101 is provided on the lower surface of the connecting sleeve 1; the positioning assembly is provided on one side of the connecting sleeve 1; the hand rest plate 2 is provided on one side of the connecting sleeve 1, and a receiving groove is provided on one side of the upper surface of the hand rest plate 2, wherein the hand rest plate 2 and the connecting sleeve 1 are both made of plastic material; the arc groove 201 is provided on the hand rest plate 2; a slot 203 is provided on one side outer wall of the hand support plate 2; an arc-shaped positioning slot 204 is provided in the inner wall of the slot 203; a connecting sheet 3 is detachably provided in the receiving slot on the upper surface of the hand support plate 2 by means of screws; a plurality of dividing strips 301 are provided on a single outer wall surface or a double outer wall surface of the connecting sheet 3. When the dividing strip 301 is provided on a single outer wall surface, the connecting sheet 3 and the dividing strip 301 can be removed and replaced according to the different left and right hands of the patient. When the double outer wall surface is provided, it can be directly turned over without replacement.
[0022] In specific implementation, the slot 101 is an arc larger than a semicircle, and the arc slot 201 is an arc less than or equal to a semicircle. During installation, the connecting sleeve 1 can be clamped on the armrest tubes on both sides of the wheelchair through the slot 101, and the hand support plate 2 is placed on the armrest tubes on both sides of the wheelchair.
[0023] During specific implementation, when the upper and lower outer walls of the connecting sheet 3 are both provided with overlapping dividing strips 301, the receiving groove on the upper surface of the palm rest plate 2 needs to be provided in an inverted convex shape to accommodate the connecting sheet 3 and the dividing strips 301. According to the different left and right hands of different patients, the connecting sheet 3 can be turned over to expose another set of dividing strips 301 to meet the needs of replacement of the left and right hands.
[0024] During specific implementation, in order to achieve the fixation between the hand support plate 2 and the connecting sleeve 1, the positioning assembly includes a positioning rod 102 and a spring pin 103 with elastic force arranged in the positioning rod 102. The outer end of the spring pin 103 is arranged in an arc shape. The positioning rod 102 is inserted into the corresponding slot 203, and the spring pin 103 is pressed against the corresponding positioning groove 204 under the action of the elastic force.
[0025] During specific implementation, in order to facilitate the disassembly between the hand support plate 2 and the connecting sleeve 1, a accommodating chamber 104 is further opened on the side of the connecting sleeve 1 close to the hand support plate 2, and a turntable 105 is arranged in the accommodating chamber 104, and the turntable 105 can be adapted to rotate in the accommodating chamber 104, and a knob 106 is rotatably arranged on the top of the connecting sleeve 1, and the bottom end of the knob 106 extends into the accommodating chamber 104 and is connected with the turntable 105. Under the rotation action of the knob 106, the turntable 105 can be driven to rotate and push the hand support plate 2 to move. When the hand support plate 2 is pushed to move, the spring pin 103 can be squeezed to disengage it from the positioning slot 204, and then the positioning rod 102 can be pulled out of the slot 203.
[0026] In specific implementation, a portion of the outer wall of the turntable 105 is arranged in a horizontal plane to fit the outer wall of the hand support plate 2, or the turntable 105 and the knob 106 are eccentrically arranged, which is another way to facilitate the turntable 105 to push the hand support plate 2.
[0027] During specific implementation, in order to prevent the patient's arm from falling off the hand support plate 2 , side plates 202 are provided on both sides of the outer wall of the hand support plate 2 .
[0028] During specific implementation, grooves 205 are provided on both sides of the outer wall of the side panel 202, and the inner cavity of the groove 205 is provided with a connecting rod 206. The setting of the groove 205 and the connecting rod 206 can facilitate the connection of the strap. After the hand support board 2 is removed, the patient can hang the strap around the neck so that the hand support board 2 continues to support the patient's arm.
[0029] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows:
[0030] When in use, the connecting sleeve 1 is clamped on the armrest tubes on both sides of the wheelchair through the clamping groove 101, and the hand support plate 2 is placed on the armrest tube through the arc groove 201. Since the hand support plate 2 and the connecting sleeve 1 are fixed together through the positioning component, the hand support plate 2 is firmly placed on the armrest tube. When a hemiplegic patient sits on the wheelchair, his arms are placed on the hand support plate 2, and his fingers are stretched and clamped between two adjacent partition strips 301. With the cooperation of the hand support plate 2 and the side plate 202, the arm of the hemiplegic patient can be prevented from slipping. When the hand support plate 2 is disassembled, the knob 106 is turned to drive the turntable 105 to rotate, and the turntable 105 pushes the hand support plate 2 to move outward. During the movement of the hand support plate 2, the spring pin 103 is squeezed, and the spring pin 103 retracts and separates from the positioning groove 204. At this time, the hand support plate 2 loses its positioning and can be removed from the connecting sleeve 1, which is very simple and convenient. When a strap is tied to the connecting rod 206 on the outer side of the side plate 202, the strap can be hung on the patient's neck, so that the disassembled hand support plate 2 continues to support the patient's arm.
[0031] The above description of the embodiments is to facilitate ordinary technicians in this technical field to understand and use the utility model. It is obvious that those familiar with the technology in this field can easily make various modifications to the embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the protection scope of the utility model.
