Specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, develop simultaneously enforcement referring to the drawings
Example further describes to this utility model.
Refering to Fig. 1, this utility model provides a kind of folding wheel chair, and including support body, described support body bottom is provided with wheel,
Wherein, described support body includes push tube 1, backing tube 2, arm-rest frame 3, mounting 4, supporting part 5 and side arm 6, and described push tube 1 connects
In described backing tube 2 top, hinged described arm-rest frame 3 and described mounting 4 on described backing tube 2, described supporting part 5 one end is hinged
In support body bottom, the other end is connected with described mounting 4, and described side arm 6 is connected to described mounting 4 bottom, also includes a support institute
State the side arm support tube 8 of side arm 6, side arm support tube 8 is L-shaped pipe, described side arm support tube 8 one end is with described support body bottom even
Connect, the other end is connected with described side arm 6.
Refering to Fig. 2, further, described mounting 4 is L-shaped support body, and mounting 4 is additionally provided with medicated cushion 9, during folding, hinged
Mounting 4 in backing tube 2 overturns around junction point, and supporting part 5, side arm 6, side arm support tube 8 overturn in the lump, and wheelchair is integrally rolled over
Mode that is folded, folding with respect to existing cross pipe, folding mode of the present utility model makes wheelchair overall more firm, it is to avoid
What the wheelchair of cross pipe foldable structure existed when advancing rocks sense and gap sense, furthermore, the wheelchair of cross pipe foldable structure in order to
Fold using thin soft seat cushion, soft seat cushion is folded up for boundary from the center, therefore soft seat cushion can only be using for example
The material of cloth material etc., soft seat cushion is not enough to the supporting force of user body, leverages the comfort taken, this reality
With new folding mode, seat cushion need not be folded up for boundary from the center, the mounting 4 of hard can be set, on mounting 4
Soft medicated cushion is set, improves the supporting force to occupant, substantially increase ride comfort.
Refering to Fig. 3 to Fig. 7, this utility model also includes locking the locking device 7 that wheelchair is in open mode, described locking
Device 7 includes the clamping section 70 being arranged at mounting 4 bottom and being connected with described supporting part 5, also includes connecting described supporting part 5 He
Described clamping section 70 draw pin 71, described draw pin 71 one end to be connected with to draw pin handle 73, draw pin 71 connect described in draw pin handle 73
One end be provided with external screw thread, described draw pin handle 73 to be provided with handle hole portion 730, be provided with described handle hole portion 730 in
Screw thread, described draw pin 71 to draw pin handle 73 to be threaded connection with described, described locking device 4 also includes elastomeric element 72, institute
State elastomeric element 72 to be arranged at clamping section 70 and draw pin 71 described in abutting.
