1, since support supporting element 71 is mounted on the support tube extended on seat of wheeled chair 51, so in long-time service
In the process, it will lead to compressive strain under the gravity that support tube is born by foot-operated 61.
2, the support tube extended will increase the volume of wheelchair after shrinking when wheelchair shrinks and gets up to place, and extend
Support tube is easy to cause rub phenomenon, further results in dangerous generation.
Utility model content
For overcome the deficiencies in the prior art, it is provided by the utility model it is a kind of applied to foldable wheelchair it is foot-operated on hold
Hold in the palm fixing piece.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of support fixing piece for wheelchair pedal, it is characterised in that: including main body, the main body includes the first cooperation
Part, the second matching piece and the supporting element among the first matching piece and the second matching piece, first matching piece are equipped with straight
Slot, second matching piece be equipped with arc groove, first matching piece and the second matching piece by supporting element be connected and fixed for
One.
In the present invention, the supporting element is triangular shape, and first matching piece and the second matching piece are obliquely installed
On two adjacent sides of the supporting element of triangular shape, the bottom surface of the triangular shape supporting element is arc surface.
In the present invention, the thickness of the supporting element from top to bottom reduces, and the front and rear sides face of the supporting element is
The arc radius of the arc surface being recessed inwardly, the arc surface being recessed inwardly from top to bottom is gradually increased.
In the present invention, the straight trough is equipped with the through-hole across supporting element, and the through-hole is described perpendicular to straight trough
Arc groove is equipped with counter sink, and the internal diameter of the counter sink is greater than the internal diameter of through-hole, the through-hole and counter sink it is parallel to each other and
On the same axis.
In the present invention, the side of second matching piece is arc surface, the centre point and circular arc of the arc surface
The centre point of slot is identical.
In the present invention, the depth of the arc groove is greater than arc radius, and the arc groove includes two and circular arc
Circular arc in slot is tangent and outwardly extending fastening plate.
The beneficial effects of the utility model are: the arc groove of the utility model can be quickly solid with seat of wheeled chair cooperation
Fixed, arc-shaped vallecular cavity can preferably cooperate with the support tube of seat of wheeled chair, so that support fixing piece is not easy in seat of wheeled chair
Support tubes on deviate from, and do not need seat of wheeled chair and extend support tube to be used cooperatively, the production cost of reduction and contraction
Volume afterwards.Meanwhile the efficiency and effect that fastening plate makes the cooperation of the support tube of support fixing piece and seat of wheeled chair fixed are more preferable.
Further, the setting of the various arc surfaces on supporting element, so that supporting element is in the case where guaranteeing best holding power, reduced life
The dosage of material is produced, and makes the quality of support fixing piece lighter, to reduce production cost.The utility model does not limit also
With using on foldable wheelchair, also can be used on conventional wheelchair or other distinct devices.In conclusion this is practical
Have many advantages, such as that structure is simple, flexibility is big, practical in novel.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the present embodiment；
Fig. 2 is the schematic diagram of internal structure of the present embodiment；
Fig. 3 is the structural schematic diagram of another angle of the present embodiment；
Fig. 4 is the using state structure diagram of the present embodiment；
Fig. 5 is the structural schematic diagram of old-fashioned wheelchair.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
It generally comprises seat of wheeled chair 5 with Fig. 4, a foldable wheelchair referring to Fig.1, be movably connected on seat of wheeled chair 5
Foot-operated 6 and fix and support foot-operated 6 support fixing piece 7.The support fixing piece 7 being wherein applied on above-mentioned wheelchair pedal 6
Main body 1 including integrated injection molding, and aforementioned body 1 is elastomer.Further, aforementioned body 1 includes the first cooperation
