Detailed Description

The invention will be further described with reference to the following specific embodiments:

referring to fig. 1 to 3, the present embodiment is a quick-release and quick-assembly foot rest structure suitable for a wheelchair, the foot rest structure can be quickly assembled on a front end straight tube 1 of a wheelchair frame, the foot rest structure includes a foot rest supporting rod 2, a foot rest 3 fixedly connected to a bottom end of the foot rest supporting rod 2 (the foot rest 3 is connected to a bottom end of the foot rest supporting rod 2 through a conventional connection manner such as bolt connection or welding), a limiting block 4 fixedly connected to a top end of the foot rest supporting rod 2 (the top end of the foot rest supporting rod 2 is bent towards a horizontal direction, the limiting block 4 is connected to a bottom surface of the top end of the foot rest supporting rod 2 through a screw), and a locking mechanism sleeved on a rod body of the foot; the top of the front end straight tube 1 of the wheelchair frame body is fixedly connected with a limiting pin 5 which is vertically arranged through a screw, the bottom of a limiting block 4 is provided with a limiting groove 41 which is vertically arranged downwards and is matched with the limiting pin 5, and the limiting of the leg support supporting rod 2 in the horizontal direction is realized through the matching of the limiting block 4 and the limiting groove 41.

In this embodiment, locking mechanism includes handle 6, bolt 7 and cup joint in the 2 body of rod of foot support bracing piece and be located the fixing base 8 at the 2 body of rod of foot support bracing piece back, the inner chamber of fixing base 8 is linked together and the logical chamber 82 that extends along vertical direction including the smooth chamber 81 that extends along the horizontal direction and with the middle section of smooth chamber 81, one side that smooth chamber 81 kept away from foot support bracing piece 2 has the opening that is linked together with the fixing base 8 outside, bolt 7 is located in smooth chamber 81 and is connected with a pressure spring 9 between the afterbody of bolt 7 and the diapire of smooth chamber 81, under the drive of pressure spring 9, the opening of the smooth chamber 81 of head roll-off of bolt 7 stretches into to predetermineeing trench 10 on the front end straight tube 1 body of wheelchair support body, the cooperation of trench 10 on head and the front end straight tube 1 body through bolt 7 realizes spacing to the vertical direction of foot support bracing piece 2.

In this embodiment, the middle part position of handle 6 hinges in the top of fixing base 8 and the bottom of handle 6 extends along the logical chamber 82 of fixing base 8 and cooperatees with the bolt 7 in the smooth chamber 81 with fixing base 8, wherein, offer the recess 71 that supplies the bottom of handle 6 to stretch into on the round pin body of bolt 7, when the top of stirring handle 6 rotates towards the direction of keeping away from the foot rest bracing piece 2, the bottom of handle 6 rotates in order to contradict and drive bolt 7 and slide towards the diapire direction of smooth chamber 81 on the recess 71 of bolt 7 towards the direction of being close to foot rest bracing piece 2 in step, thereby make the head of bolt 7 retract and break away from the cooperation with trench 10 on the straight tube body of front end 1.

In the actual use process, when the foot rest structure needs to be disassembled, only the top end of the handle 6 needs to be shifted by a hand in the direction far away from the foot rest supporting rod 2, so that the bottom end of the handle 6 rotates in the direction close to the foot rest supporting rod 2, in the process, the bottom end of the handle 6 interferes with the groove 71 of the plug 7, so that the plug 7 is forced to the direction of the foot rest support rod 2, and the plug 7 slides towards the bottom wall of the sliding cavity 81, namely, the head part of the plug pin 7 retracts towards the sliding cavity 81 to be separated from the matching with the slot position 10 on the pipe body of the front end straight pipe 1, the limit of the foot rest supporting rod 2 in the vertical direction is released, at the moment, the foot rest supporting rod 2 is lifted upwards, so that the limiting groove 41 of the limiting block 4 at the top end of the foot-supporting rod 2 is separated from the matching with the limiting pin 5, the limit of the foot support supporting rod 2 in the horizontal direction is released, and at the moment, the foot support supporting rod 2 can be detached;

when the foot rest structure needs to be reinstalled, the limiting groove 41 of the limiting block 4 at the top end of the foot rest supporting rod 2 is matched with the limiting pin 5 again, then the bolt 7 is kept in a retraction state by stirring the handle 6, then the foot rest supporting rod 2 is rotated (at the moment, the foot rest supporting rod 2 rotates by taking the limiting pin 5 as a central shaft) until the opening of the sliding cavity 81 is aligned with the groove position 10 on the tube body of the straight tube 1 at the front end of the wheelchair frame body, the handle 6 is loosened, so that the head of the bolt 7 extends out of the opening of the sliding cavity 81 and is inserted into the groove position 10 on the tube body of the straight tube 1 at the front end under the pushing of the pressure spring 9, the horizontal direction and the vertical direction of the foot rest supporting rod 2 are completed again, and the foot rest supporting rod 2 is fixed; the disassembly process and the installation process are simple and quick, the practicability is high, and good use experience is achieved.

In this embodiment, a limit seat 11 is fastened to the tube body of the straight tube 1 at the front end of the wheelchair frame, and a slot 10 matched with the plug pin 7 is opened on the surface of the limit seat 11 facing the footrest support bar 2.

In the embodiment, the handle 6 has a hollow structure in the middle, so that the handle 6 can be more easily operated by a user sitting on the wheelchair.

In this embodiment, the top of one side of the front end straight tube 1 of the fixing seat 8 facing the wheelchair frame body is further formed with a supporting portion 83, the end surface of the supporting portion 83 facing the front end straight tube 1 is in the shape of an arc groove 71, and after the foot support structure is installed on the front end straight tube 1 of the wheelchair frame body, the end surface of the arc groove 71 of the supporting portion 83 is attached to the tube body of the front end straight tube 1, so as to support the foot support structure.

In addition, it should be noted that the names of the parts and the like of the embodiments described in the present specification may be different, and all the equivalent or simple changes made according to the structure, the features and the principle of the present invention are included in the protection scope of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
