Description

The foot-operated structure of turning up of wheelchair

Technical field

This utility model relates to a kind of wheelchair for the disabled's use, relates in particular to the foot-operated structure of turning up of wheelchair.

Background technology

At present, wheelchair for the disabled's use, for adapting to the different demands of user, be provided with foot-operated pipe on it mostly, be equipped with on the foot-operated pipe respectively and place the supporting plate of shank and place the foot pedal apparatus of foot for the disabled, make lower limb or the foot of the disabled be in the state of unfolding or loosening as far as possible, to promote the rehabilitation and the healing of the disabled legs and feet portion as early as possible, or make the patient feel more comfortable, reduce the misery that the health permanent disability is brought as far as possible, but traditional foot-operated Guan Jun is designed to longitudinally stay pipe as the axial rotary external rotation, making things convenient for up and down wheelchair of the disabled, but the limitation of this structure is: if on the foot-operated pipe supporting plate has been installed, when user need play wheelchair, at first need shank is moved, on lift, could be rotated operation to foot-operated pipe, but for the comparatively serious patient of permanent disability, even if a such little trick, also can make the patient feel effort or painful, in addition need by other people help; Certainly in order to reduce patient's misery, also supporting plate can be designed to can be around the reversible structure of foot-operated pipe rotation, but like this, can make the complex structural designsization of wheelchair undoubtedly, increase the production cost of wheelchair, this structure is under needs of patients during wheelchair, though do not need again moving shank to the patient, but need upset supporting plate earlier, could rotate foot-operated pipe then, operating still shows trouble.

In view of the above problems, the inventor designs the flip angle of foot-operated pipe, and this case produces thus.

The utility model content

The purpose of this utility model is to provide a kind of foot-operated structure of turning up of wheelchair, can farthest reduce the action of patient legs and feet portion in wheelchair process up and down, reduces patient's slight illness, and it is simple in structure, and is easy to operate.

To achieve these goals, the technical solution of the utility model is:

A kind of foot-operated structure of turning up of wheelchair comprises stay pipe, Movable joint, holder and joystick, and wherein, stay pipe is fixed on the wheelchair, and the ora terminalis of stay pipe has a hole clipping; Movable joint is fixedlyed connected with foot-operated pipe, and Movable joint also has one and be socketed on the inner or outside socket pipe of stay pipe, along the circumferential direction is provided with first perforation and second on the socket pipe and bores a hole; The two ends of holder are placed on respectively on stay pipe and the socket pipe, and joystick is installed on the holder; The inboard end of joystick has mounting groove, and a spring is installed in the mounting groove, and the other end has a bayonet lock.

Described stay pipe is oblique setting.

After adopting such scheme, this utility model is when normal operating condition, and the perforation of first on the socket pipe is corresponding with the hole clipping on the stay pipe, and the bayonet lock on the joystick sees through first perforation and the hole clipping realization location to Movable joint; When user needs up and down wheelchair, push joystick, the compression spring, bayonet lock is deviate from from first perforation and hole clipping, removes the location to Movable joint, at this moment, stir foot-operated pipe around the rotation of the axle center of stay pipe, to second perforation and hole clipping corresponding position, discharge joystick, realize location again to Movable joint.Because of foot-operated pipe is with axially the overturning as rotating shaft of stay pipe, need not before the foot-operated pipe of upset, to move shank and foot, thereby farthest reduced patient's misery, and simple in structure, it is easy to operate.

Below in conjunction with drawings and the specific embodiments this utility model is done and to be described in further detail.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of foot-operated structure of turning up of wheelchair comprises stay pipe 1, Movable joint 2, holder 3 and joystick 4.

Wherein, stay pipe 1 is fixed on the wheelchair, and as preferred embodiment a kind of, the stay pipe of present embodiment is oblique setting, and the ora terminalis of stay pipe 1 has a hole clipping 11.

Movable joint 2 is fixedlyed connected with foot-operated pipe 5, and Movable joint 2 also has one and be socketed on stay pipe 1 inner or outside socket pipe 21, along the circumferential direction is provided with first perforation, 211 and second perforation 212 on the socket pipe 21.

The two ends of holder 3 are placed on respectively on stay pipe 1 and the socket pipe 21.

Joystick 4 is installed on the holder 3, and joystick 4 inboard ends have mounting groove 41, and springs 6 are installed in the mounting groove 41, and the other end has a bayonet lock 42.

As Fig. 3, in conjunction with Fig. 1, shown in Figure 2, when normal operating condition, foot-operated pipe 5 is positioned at primary importance, on the socket pipe 21 first perforation 211 is corresponding with the hole clipping 11 on the stay pipe 1, and the bayonet lock 42 on the joystick 4 sees through first perforation 211 and the hole clipping 11 realizations location to Movable joint 2.

When user needs up and down wheelchair, at first push joystick 4, compression spring 6, bayonet lock 42 is deviate from from first perforation 211 and hole clipping 11, releasing is to the location of Movable joint 2, stirs foot-operated pipe 5 then and rotates to the second position around the axle center of stay pipe 1, meanwhile, second perforation, 212 (not shown)s are corresponding with hole clipping 11, discharge joystick 4, spring 6 resets, and realizes the location to Movable joint 2 again, at this moment, the patient just can be safely, wheelchair up and down easily.

The foot-operated pipe 5 of said structure is because of being axially to be rotated adjusting as rotating shaft with stay pipe 1, foot-operated pipe 5 is withdrawn primary importance from the side, rotate to the second position, in this process, need not to move shank and foot, thereby farthest reduced the painful and inconvenient of patient, this is simple in structure, and operation is convenient.

The above is preferred embodiment of the present utility model only, is not the restriction to this case practical range, and all equivalent variations of doing according to the design key of this case all should fall into the protection domain of this case.
