[0002] The existing wheelchair usually increases the guard plate below the handrail side, can block the user's body or other articles in the use process, prevents clothes and other articles from leaking and falling from the space below the handrail or being clamped on the wheel, and safety problems are prone to occur.

[0003] In the Chinese patent application with publication number CN216168365U, a wheelchair guard plate passes through the bed structure is disclosed, including the guard plate component hinged on the left and right sides of the wheelchair frame and the handrail hinged on the left and right sides of the backrest of the wheelchair; the handrail is arranged at the top end of the guard plate component; on the wheelchair frame, the back surface of the guard plate component is provided with a linkage rod, one end of the linkage rod is connected with a pull rod type air cylinder, and the other end of the pull rod type air cylinder is connected with the wheelchair frame.

[0004] The wheelchair handrail side guard plate structure in the prior art is relatively complex, when customers have different shape or appearance requirements, it cannot be quickly disassembled and replaced, and the cost required for replacement is high. INVENTION CONTENTS

[0005] The utility model aims at providing a wheelchair handrail side guard plate fixing structure, solves the problems of the prior art that cannot be quickly disassembled and replaced, and high replacement cost.

[0006] The above technical purpose of the utility model is mainly solved through the following technical scheme: a wheelchair handrail side guard plate fixing structure, including two symmetrical wheelchair handrails, the wheelchair handrails extend downward at the front and rear ends and are connected to form a through hole, the opening of the through hole towards the other wheelchair handrail is provided with a guard plate for closing the through hole, a plurality of first magnetic elements are arranged at the edge of the guard plate, and a plurality of second magnetic elements magnetically attracted to the first magnetic elements are arranged at the edge of the through hole; the guard plate is quickly fixed with the handrail through the mutual attraction of the first magnetic elements and the second magnetic elements, the through hole is closed, a blockage is formed, and the first magnetic elements and the second magnetic elements are arranged, so that the guard plate can be quickly disassembled and installed, different guard plates can be customized and replaced according to customer requirements, production efficiency is improved, and cost is reduced.

[0007] As a preferred, the edge of the through hole is provided with an annular positioning groove matched with the edge of the guard plate; the annular positioning groove is arranged to limit the edge of the guard plate, so as to position the guard plate in the annular positioning groove, keep the fixation of the guard plate stable, and avoid the loosening and deviation of the guard plate.

[0008] Preferably, the first magnetic component is bonded to the side of the wheelchair armrest near the same side of the edge of the guard plate using adhesive; the bonding of the first magnetic component to the guard plate facilitates the installation of the first magnetic component and improves the production efficiency of the guard plate.

[0009] Preferably, the annular positioning groove has multiple grooves on the side that contacts the end face of the guard plate for accommodating the second magnetic component, and the second magnetic component is bonded to the grooves; the grooves can position and fix the second magnetic component, maintain the stability of the second magnetic component, and ensure that the annular positioning groove can maintain its magnetic attraction function when different guard plates are replaced.

[0010] Preferably, neither of the two opposing sides of the guard plates protrudes beyond the edge of the through hole; this avoids the guard plates protruding beyond the through hole and rubbing or squeezing against the wheelchair seat or side frame, which could cause damage to the guard plates, and also increases the movable space of the guard plates in the width direction, so as to facilitate the disassembly and installation of the guard plates.

[0011] Therefore, this utility model has the advantages of enabling quick disassembly and installation of the protective plate, so as to facilitate the customization and replacement of different protective plates according to customer needs, thereby improving production efficiency and reducing costs.

[0014] Figure 3 yes Figure 1 A schematic diagram of the structure of the protective plate. Detailed Implementation

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] like Figures 1-3 As shown, a wheelchair armrest side panel fixing structure includes two symmetrically arranged wheelchair armrests 1. The front and rear ends of the wheelchair armrests 1 extend downward and connect to form a through hole 11. The opening of the through hole 11 facing the other wheelchair armrest 1 is provided with a guard plate 12 that closes the through hole 11. Several first magnetic elements 121 are provided at the edge of the guard plate 12, and several second magnetic elements 111 that are magnetically attracted to the first magnetic elements 121 are provided at the edge of the through hole 11. The opposite sides of the two guard plates 12 do not protrude from the edge of the through hole 11.

[0017] The two armrests are symmetrically positioned on both sides of the seat. The front and rear ends of the armrests curve downwards and connect to form a through hole, which is located above the seat. The guard plate is fixed to the edge of the through hole of the armrest by the attraction of a first magnetic component and a second magnetic component, thus achieving a magnetic attraction structure. The first and second magnetic components are magnets with opposite magnetic properties. When the guard plate is fixed to the edge of the through hole, the opposite sides of the two guard plates do not protrude from the edge of the through hole (i.e., the inside of the armrest), avoiding pressure and wear on the guard plate caused by the seat or other components. The guard plate can be quickly disassembled and installed through the magnetic attraction structure to replace guard plates with different appearances or shapes to meet customer needs.

[0018] like Figures 2-3 As shown, an annular positioning groove 112 is provided at the edge of the through hole 11 to mate with the edge of the guard plate 12. The first magnetic component 121 is glued to the side of the guard plate 12 near the wheelchair armrest 1 on the same side. The side of the annular positioning groove 112 that contacts the end face of the guard plate 12 is provided with multiple grooves 113 for accommodating the second magnetic component 111. The second magnetic component 111 is glued to the grooves 113. The annular positioning groove is provided at the edge of the through hole to mate with the edge of the guard plate. The side wall of the annular positioning groove abuts against the edge of the guard plate, and the bottom surface of the annular positioning groove abuts against the end face of the guard plate. The first magnetic component is glued to the edge of the guard plate, and the second magnetic component is stuck in the groove and glued. The relative positions of the first magnetic component and the second magnetic component are consistent, and the first magnetic component and the second magnetic component are evenly distributed in the annular positioning groove and at the edge of the guard plate, respectively, to achieve a stable magnetic attraction.
