Detailed Description
The present invention will be further described with reference to the following specific embodiments.
Referring to fig. 1 to 5, in the present embodiment, a wheelchair with a foldable storage pedal 22 includes a wheelchair frame 1 and a pedal assembly 2, wherein the wheelchair frame 1 includes a left frame and a right frame which are symmetrically arranged, and the left frame and the right frame each include an upper support cross rod 11, a front support vertical rod 13 and a lower support cross rod 12 which are located below a seat cushion, and two ends of the front support vertical rod 13 are respectively connected with front ends of the upper support cross rod 11 and the lower support cross rod 12 by welding. In addition, the left frame and the right frame can be horizontally folded together through a folding mechanism 3, wherein the folding mechanism 3 is an X-shaped cross rod connected through a rotating shaft.
In this embodiment, the pedal assembly 2 includes two pedal supports 21 and two pedals 22 respectively hinged to the lower ends of the two pedal supports 21, where the pedals 22 can be directly hinged to the pedal supports 21, or indirectly hinged to the pedal supports 21 through a preset fixing rod 25 as shown in fig. 3, specifically: one end of the fixed rod 25 is in hinged fit with the pedal bracket 21 through a preset bolt so that the fixed rod 25 can swing back and forth around the hinged point, and the pedal plate 22 is fixedly arranged on the fixed rod 25 through a locking screw (the bottom surface of the pedal plate 22 is in contact fit with the fixed rod 25); secondly, the two pedals 22 are hinged to each other, that is, the other ends of the two fixing rods 25 supporting the two pedals 22 are hinged to each other through bolts, so as to realize an indirect hinge manner between the two pedals 22, and therefore, the two pedal supports 21 can be horizontally folded together and the two fixing rods 25 can be folded upwards around opposite directions (equivalent to the two pedals 22) through the hinge between the pedal supports 21 and the fixing rods 25 and the hinge between the two fixing rods 25.
In this embodiment, the upper end of each pedal support 21 is formed with a bent portion 23 extending backward and bending, and the other end of each folded portion is formed with a connecting portion 24, the two connecting portions 24 are respectively hinged to the two lower supporting rods 12 through preset bolts, and the two hinge points are aligned, so that the two connecting portions 24 can respectively turn over around the hinge points between the two lower supporting rods 12, because the two pedals 22 are hinged to each other, the two connecting portions 24 are turned over synchronously, and the two folding supports and the two folding portions are turned over synchronously with the two connecting portions 24, so that the connecting portions 24 are turned over around the hinge points between the connecting portions 24 and the lower supporting rods 12 to synchronously unfold the pedal supports 21 and the bent portions 23 forward or fold backward, that is, as shown in fig. 1, the counterclockwise turning is defined as a forward turning action, the clockwise turning is backward turning, when the pedal support 21 and the bending part 23 are unfolded synchronously forward, the two pedals 22 are turned to a rated position along with the pedal support 21 along the counterclockwise direction, and at the moment, the two pedals 22 can be turned and unfolded downwards in advance or turned and unfolded downwards after the pedal support 21 is unfolded forward; on the contrary, when the pedal support 21 and the bending portion 23 are folded backwards synchronously, the two pedals 22 are turned clockwise along with the pedal support 21 to the rated position, and at this time, the two pedals 22 can be turned upwards in advance for folding or turned upwards for folding after the pedal support 21 is folded inwards.
The pedal support 21 of this embodiment, the shape of "U" style of calligraphy has been constituted between the portion of bending 23 and the connecting portion 24 three, thereby make pedal support 21 that closes backward overturn supreme below region that props horizontal pole 11, promptly, two footboards 22 overturn the supreme below region that props horizontal pole 11 afterwards, thereby make two footboards 22 all turn over to turn over and accomodate in the seatpad below region, the problem that traditional footboard 22 turned over to the seatpad top region has been solved, folding back wheelchair occupation space is littleer and more pleasing to the eye.
Referring to fig. 5, in the present embodiment, the two limiting portions 131 protruding inwards are formed on the two front supporting vertical rods 13, and the two limiting portions 131 are aligned and respectively protrude to the turning path where the two bent portions 23 turn forward, so that the two limiting portions 131 are respectively used for limiting the two folded portions that are unfolded forward in an interference manner, that is, the limiting portions 131 are arranged at the rated position to limit the folded portions in an interference manner, which is equivalent to limiting the pedal bracket 21 and the pedal plate 22 that turn forward, and simultaneously, supporting the pedal plate 22.
The above-described embodiments are merely preferred embodiments of the present invention, which are not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents of the embodiments of the invention without departing from the scope of the invention. Therefore, the content of the technical scheme of the utility model, according to the equivalent change made by the idea of the utility model, should be covered in the protection scope of the utility model.
