Abstract
The invention discloses a quickly detaching core shaft of a wheelchair and relates to the field of wheelchair parts. The quickly detaching core shaft comprises a cap press stud, a shaft core and a shaft body, wherein a compression spring is horizontally arranged between the cap press stud and the shaft body; a steel ball is arranged at the tail end of the shaft body; a trapezoidal groove is formed in the tail end of the shaft core. During mounting, the compression spring is extruded, and the steel ball at the tail end of the shaft body is fixed to a wheel; during detachment, the compression spring is extruded, the steel ball falls into the trapezoidal groove, and a wheelchair wheel is convenient to withdraw. The quickly detaching core shaft is simple in structure and easy to manufacture.
Description
Technical field
The present invention relates to wheelchair field of components, especially a kind of wheelchair quick detaching core shaft.
Background technology
At present, wheelchair each side have a wheel, each wheel has axletree, between axletree and wheel, is bolted fixing vehicle wheel.The deficiency of its existence is that wheel is not quick detachable, and the installation of wheel need to realize by spanner conventionally, and complex operation is wasted time and energy.
Summary of the invention
In order to overcome the not easily detachable defect of existing wheel chair wheel, the invention provides a kind of wheelchair quick detaching core shaft, use this quick detaching core shaft when wheel chair wheel installing, can Fast Installation wheel chair wheel, also can dismantle rapidly wheel chair wheel simultaneously.
For achieving the above object, the present invention proposes so a kind of technical scheme: a kind of wheelchair quick detaching core shaft, comprise block snapper, axle core and axis body, block snapper, axle core and axis body are threaded connection and are integrated, Compress Spring is laterally installed between described block snapper and axis body, and the end punching of described axis body is provided with steel ball; The end of described axle core is offered dovetail groove; Between described axis body and block snapper, adjusting nut is installed.
The invention has the beneficial effects as follows: when mounted, press Compress Spring, the steel ball fixing vehicle wheel of axis body end; When dismounting, press Compress Spring, steel ball falls into dovetail groove, makes the convenient extraction of wheel, and the installation and removal of wheel need to, by spanner, can not mount and dismount wheel chair wheel by wheelchair quick detaching core shaft fast, easy to use, time saving and energy saving.The present invention is simple in structure, is easy to manufacture.

In figure, 1, block snapper; 2, adjusting nut; 3, Compress Spring; 4, axle core; 5, axis body; 6, dovetail groove; 7, steel ball; 8, quick detaching core shaft; 9, wheel; 10, hand rim; 11, trailing wheel axle sleeve.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
In conjunction with Fig. 1-5, take wheelchair quick detaching core shaft as example, wheelchair quick detaching core shaft comprises block snapper 1, axle core 4 and axis body 5, and Compress Spring 3 is laterally installed between described block snapper 1 and axis body 5; The end of described axis body 5 is provided with steel ball 7; The end of described axle core 4 is offered dovetail groove 6; Between described axis body 5 and block snapper 1, adjusting nut 2 is installed, wheel 9 and hand rim 10 are arranged on wheelchair trailing wheel axle sleeve 11 by quick detaching core shaft 8.
Regulate the adjusting nut 2 on axis body 5, change the distance between block snapper 1 and adjusting nut 2, thereby in the time pressing block snapper 1, change the distance of dovetail groove 6 and steel ball 7, make steel ball 7 be easy to enter dovetail groove 6, Convenient wheelchair quick detaching core shaft 8 horizontally slips in the time of installation and removal wheel chair wheel.
When wheelchair wheel 9 is installed, press block snapper 1, block snapper 1 pushes Compress Spring 3, and axle core 4 laterally travels forward, the dovetail groove 6 of axle core 4 ends moves forward, the steel ball 7 of axis body 5 ends falls into the dovetail groove 6 that axle core 4 ends are offered, and axis body 5 is fitted into trailing wheel axle sleeve 11, treats that axis body 5 arrives trailing wheel axle sleeve 11 ends, unclamp block snapper 1, Compress Spring 3 is upheld, and after the effect lower trapezoid groove 6 of elastic force, moves, and extrudes steel ball 7, steel ball 7 withstands trailing wheel axle sleeve 11, fixes wheelchair wheel 9.
When dismounting wheelchair wheel 9, pin block snapper 1, block snapper 1 pushes Compress Spring 3, and axle core 4 laterally travels forward, the dovetail groove 6 of axle core 4 ends moves forward, pull quick detaching core shaft 8 backward, and steel ball 7 is got into dovetail groove 6 by trailing wheel axle sleeve 11, extract backward quick detaching core shaft 8 out, wheelchair wheel 9 successfully unloads.
Claims (3)
