Abstract
The utility model discloses a hitching leg mechanism for wheelchair, a serial communication port, include: the foot pad is arranged at one end of the arc-shaped hitching leg connecting rod, and a mounting hole is formed in the other end of the arc-shaped hitching leg connecting rod; the small wheel seat of the wheelchair is connected with the mounting hole of the arc-shaped hitching leg connecting rod sequentially through the foot stand rotating shaft and the foot stand shaft which are matched with each other, so that the hitching leg mechanism for the wheelchair rotates around the mounting hole. The utility model discloses a hitching leg mechanism for wheelchair can rotate the operation as required, more convenient to use and folding.
Description
Technical Field
The utility model relates to a wheelchair field of making, concretely relates to hitching leg mechanism and wheelchair for wheelchair.
Background
The hitching leg of the existing wheelchair can not rotate or can only rotate the foot pad part for storage, or a non-woven fabric foot pad is adopted for convenient storage, however, the volume of the stored foot pad is still larger, the use feeling of the latter is not good, and the non-woven fabric is not dirty.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defects of the prior art, an object of the present invention is to provide a hitching leg mechanism for a wheelchair.
The second purpose of the utility model is to provide a wheelchair comprising the hitching leg mechanism for wheelchair.
In order to realize one of the purposes of the utility model, the adopted technical scheme is as follows:
a footrest mechanism for a wheelchair, comprising:
the foot pad is arranged at one end of the arc-shaped hitching leg connecting rod, and a mounting hole is formed in the other end of the arc-shaped hitching leg connecting rod;
the small wheel seat of the wheelchair is connected with the mounting hole of the arc-shaped hitching leg connecting rod sequentially through the foot stand rotating shaft and the foot stand shaft which are matched with each other, so that the hitching leg mechanism for the wheelchair rotates around the mounting hole.
In a preferred embodiment of the present invention, a first gasket is installed on a contact surface of the foot stool rotating shaft and the small wheel seat.
In a preferred embodiment of the present invention, the second gasket is mounted on the inner screw of the leg shaft and then mounted on the mounting hole.
In a preferred embodiment of the present invention, the rotation angle of the leg hanging mechanism for wheelchair is 0 ° to 120 °.
In order to realize the second purpose of the utility model, the adopted technical scheme is:
a small wheel seat of the wheelchair is provided with the foot hanging mechanism for the wheelchair.
The beneficial effects of the utility model reside in that:
the utility model discloses a hitching leg mechanism for wheelchair can rotate the operation as required, more convenient to use and folding.

Detailed Description
The foot-hanging mechanism 100 for wheelchair shown in fig. 1-4 comprises an arc-shaped foot-hanging connecting rod 110, wherein a foot pad 112 is installed at one end 111 of the arc-shaped foot-hanging connecting rod 110, and a mounting hole 114 is formed at the other end 113 of the arc-shaped foot-hanging connecting rod 110.
The small wheel seat 210 of the wheelchair 200 is connected with the mounting hole 114 of the arc hitching leg connecting rod 110 through the foot stand rotating shaft 120 and the foot stand shaft 130 which are matched in sequence, so that the hitching leg mechanism 100 for the wheelchair rotates around the mounting hole 114, and the rotating angle is 0-120 degrees.
In order to buffer the movement of the whole structure, a gasket 140 is installed on the contact surface of the foot stool rotating shaft 120 and the small wheel seat 210. The inner screw 131 of the foot shaft 130 is first provided with the gasket 150 and then is mounted with the mounting hole 114.
Because of possessing the above structure, the utility model discloses a theory of operation lies in:
the arc-shaped hitching leg connecting rod 110 is first installed on the small wheel seat 210 of the wheelchair 200 through the spacer 140, the foot stool rotating shaft 120, the spacer 150 and the foot stool shaft 130.
Under different use environments, the position of the chair hitching leg mechanism 100 is rotationally adjusted by rotating the arc hitching leg connecting rod 110 according to requirements, and the maximum rotatable value is 120 degrees.
