Problems solved by technology

However, due to the design and manufacturing errors of the common wheelchair folding mechanisms currently on the market, it is often difficult to open and close the folding mechanism, causing a severe jamming feeling, or the position of the support part is shifted after opening, resulting in the support part not falling correctly on the corresponding position. position, a problem that plagues the industry as a whole

Embodiment 1

[0028] refer to figure 1 , which is a structural schematic diagram of the expanded state of the regulating strut structure of the present invention.

[0029] As shown in the figure, an adjustable strut structure is used to form the support structure of the wheelchair and realize the rapid folding of the wheelchair. The adjustable strut structure includes an X-shaped strut 71, an auxiliary strut 72, a vertical Bracket 73; the auxiliary strut 72 is used to realize the reinforced connection of the X-shaped support plate 71 and the vertical bracket 73, combined with image 3 As shown, it is a schematic diagram of the auxiliary support rod for adjusting the structure of the support plate in the present invention. The auxiliary support rod 72 includes a long hole support rod 723, and one end of the long hole support rod 723 is provided with a long hole 721, and the long hole 721 Connected to the X-shaped support plate 71 through a first pin shaft 741, the other end of the long hole...

Embodiment 2

[0031] As described above, the structure of the adjusting support plate, the difference of this embodiment is that, in combination with figure 1 , figure 2 , image 3 As shown, the lower end of the X-shaped support plate 71 is connected to the lower end of the vertical support 73 through a fourth hinge 744, the X-shaped support plate 71 is provided with a first pole 711, and the vertical support 73 is provided with There is a pole frame 731 , and the first pole 711 cooperates with the pole frame 731 to realize the fixing of the upper end of the X-shaped support plate 71 and the upper end of the vertical support 73 . The top of the vertical support 73 is provided with a second pole 732, and the bottom of the vertical support 73 is provided with a third pole 733. 73, so that the vertical support 73 on the same side is fixed. The elongated hole strut 723 is also provided with an arc-shaped groove 725, which is used to prevent the elongated hole strut 723 from interfering with...

Embodiment 3

[0035] As mentioned above to adjust the support plate structure, the present embodiment differs from it in that, as figure 1 As shown, the X-shaped support plate 71 is also provided with a second pin shaft 742, which is used to connect the cross-shaped support plates of the X-shaped support plate 71, so as to realize the winding of the X-shaped support plate 71. turn.

[0036] When the adjustment support plate structure is pressed down from the folded state to the unfolded state, the X-shaped support plate 71 exerts an oblique downward force on the auxiliary support rod 72 along the long axis direction of the auxiliary support rod 72. At this time Inside the auxiliary support rod 72, the clamping seat 724 acts against the spring 722 to apply an oblique downward force to the long hole support rod 723, and the long hole support rod 723 continues to transmit the force to the vertical support 73, Thereby, the vertical support 73 is urged to expand to both sides.

Abstract

An adjusting supporting plate structure comprises an X-type supporting plate, a vertical support and auxiliary supporting rods used for reinforcing and connecting the X-type supporting plate and the vertical support; each auxiliary supporting rod comprises a slot hole supporting rod, a clamping base and a spring, wherein a slot hole is formed in one end of the slot hole supporting rod, the end, provided with the slot hole, of the slot hole supporting rod penetrates through the clamping base, the spring is arranged in the slot hole and placed in the clamping base together with the slot hole supporting rod, one end of the spring abuts against the slot hole, and the other end of the spring abuts against the clamping base. The structural form of the slot hole has adjusting and self-adaptive functions, is used for eliminating errors caused by design and manufacturing and can carry out small-range adjustment in the slot hole when a first lapping rod falls, so that the first lapping rod falls into a lapping rod frame more easily, and it is avoided that the first lapping rod falls inaccurately due to design and manufacturing errors.

Description

technical field [0001] The invention relates to a wheelchair support device, in particular to an adjustment support plate structure. Background technique [0002] It can be said that wheelchairs are often used in medical rehabilitation. For the elderly, central nervous diseases, systemic failure, and patients with impaired or lost walking function, wheelchairs are an indispensable tool in their lives and are widely used. . However, most of the current wheelchairs are relatively heavy, so they are very inflexible when transporting them. Due to the relatively large space of the wheelchair, the various parts of the wheelchair need to be disassembled when moving, and they need to be assembled after transporting. Such an operation is very cumbersome. , reducing its practical performance, it is also very inconvenient during maintenance, and such disassembly and assembly for a long time also affects the service life of the wheelchair. The currently commonly used wheelchair foldin...
