The specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.
This utility model provides a kind of wheelchair folding handles, as illustrated in fig. 1 and 2, the lower folding 12 that comprises folding 11 and be attached thereto by connecting axle 13, lower folding 12 comprises integrated link 12a and columniform grip end 12b, the cross section of link 12a is arch door shape, the circular arc center of circle in the center of circle of the cross section of grip end 12b and the cross section of link 12a is on same straight line, and the arc diameter in link 12a cross section is less than the diameter of the cross section of grip end 12b.One end of upper folding 11 is hollow shell-like structure, and the link 12a of lower folding 12 is set in the hollow shell-like structure of folding 11; On the link 12a of lower folding 12, be also provided with a through hole 12c, the two sides of the hollow shell-like structure of upper folding 11 are respectively equipped with the first pin-and-hole 11a mating with through hole 12c, and connecting axle 13 runs through through hole 12c and two the first pin-and-hole 11a.Female thread flat mouth bolt and flat mouth screw that connecting axle 13 is matched by one group of screw thread form, and during assembling, workman only need inject through hole by female thread flat mouth bolt, by flat mouth screw precession female thread flat mouth bolt, easy to assembly quick.On the link 12a of lower folding 12, be provided with lock control parts, lock control parts are used for upper folding 11 and the relative position of the coupling part of lower folding 12 are fixed or discharge; The corresponding lock control parts of upper folding 11 place is provided with locking hole 11b, the corresponding locking hole 11b of link 12a place is provided with counterbore 12d, lock control parts comprise spanner 14, latch, and latch passes locking hole 11b, counterbore 12d and spanner 14 successively, and upper folding 11, lower folding 12 and spanner 14 are fixed.Refer to Fig. 1 and Fig. 5, when Wheelchair back folding structure of the present utility model need to fold, the cocked spanner 14 that only need make progress, after latch 15 departs from the pin-and-hole 11a on upper folding 11, rotates upper folding 11 around connecting axle 13.
Technique effect of the present utility model is, by optimizing structure and the size of lower folding, has reduced material usage, has reduced machining amount, has effectively reduced production cost.And can assemble fast, and person easy to use operation when folding, user is folding without just wheelchair dismantle very energetically, and this folding back structure can repeatedly fold nothing and wear and tear, durable in use.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes this utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
