Abstract
The utility model discloses a wheel chair quick release mandrel and relates to the field of wheel chair components. The wheel chair quick release mandrel comprises a nut cap lifting button, a shaft core and a shaft body. A compression spring is horizontally arranged between the nut cap lifting button and the shaft body. A steel ball is installed at the tail end of the shaft body, and a trapezoid groove is formed at the tail end of the shaft core. When the quick release mandrel of the wheel chair is installed, the compression spring is squeezed, and the steel ball which is arranged at the tail end of the shaft body fixes a wheel. When the wheel chair quick release mandrel is dismantled, the compression spring is squeezed, and the steel ball drops into the trapezoid groove and the wheel chair can be conveniently drawn out. The quick release mandrel of the wheel chair is simple in structure and easy to manufacture.
Description
Technical field
This utility model relates to the wheelchair field of components, especially a kind of wheelchair quick detaching core shaft.
Background technology
At present, wheelchair a wheel each side arranged, each wheel has axletree, is bolted fixing vehicle wheel between axletree and the wheel.The deficiency of its existence is that wheel is not quick detachable, and the installation of wheel need to realize by spanner usually, and complex operation is wasted time and energy.
Summary of the invention
In order to overcome the existing not easily detachable defective of wheel chair wheel, this utility model provides a kind of wheelchair quick detaching core shaft, uses this quick detaching core shaft when wheel chair wheel is installed, can the Fast Installation wheel chair wheel, also can dismantle rapidly wheel chair wheel simultaneously.
For achieving the above object, the utility model proposes a kind of like this 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 laterally is installed between described block snapper and the axis body, and the end punching of described axis body is equipped with steel ball; The end of described axle core is offered dovetail groove; Between described axis body and the block snapper adjusting nut is installed.
The beneficial effects of the utility model are: when mounted, press Compress Spring, the steel ball fixing vehicle wheel of axis body end; Press Compress Spring during dismounting, steel ball falls into dovetail groove, makes the convenient extraction of wheel, and the installation and removal of wheel need to can not mount and dismount wheel chair wheel by the wheelchair quick detaching core shaft fast by spanner, and are easy to use, time saving and energy saving.This utility model is simple in structure, is easy to make.

Among the figure, 1, the block snapper; 2, adjusting nut; 3, Compress Spring; 4, the axle core; 5, axis body; 6, dovetail groove; 7, steel ball; 8, quick detaching core shaft; 9, wheel; 10, hand rim; 11, the trailing wheel axle sleeve.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
In conjunction with Fig. 1-5, take the wheelchair quick detaching core shaft as example, the wheelchair quick detaching core shaft comprises block snapper 1, axle core 4 and axis body 5, and Compress Spring 3 laterally is installed between described block snapper 1 and the axis body 5; The end of described axis body 5 is equipped with steel ball 7; The end of described axle core 4 is offered dovetail groove 6; Between described axis body 5 and the block snapper 1 adjusting nut 2 is installed, wheel 9 and hand rim 10 are installed on the wheelchair trailing wheel axle sleeve 11 by quick detaching core shaft 8.
Regulate the adjusting nut 2 on the axis body 5, change the distance between block snapper 1 and the adjusting nut 2, thereby when 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 when the installation and removal wheel chair wheel.
When being installed, wheelchair wheel 9 presses block snapper 1, block snapper 1 extruding Compress Spring 3, and axle core 4 laterally travels forward, dovetail groove 6 reaches of axle core 4 ends, 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 moves behind the effect lower trapezoid groove 6 of elastic force, extrudes steel ball 7, steel ball 7 withstands trailing wheel axle sleeve 11, fixes wheelchair wheel 9.
Pin block snapper 1 during dismounting wheelchair wheel 9, block snapper 1 extruding Compress Spring 3, axle core 4 laterally travels forward, dovetail groove 6 reaches of axle core 4 ends, the 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.
