Central siphon is equipped with the spindle tube extended after fixed central siphon to frame outside, the axis being equipped on spindle tube in fixed central siphon
It holds, the bull wheel of wheelchair is installed on bearing, and be equipped with the interior device for quickly disassembling being equipped on spindle tube.It is set on frame inside spindle tube
It is equipped with the extension with spindle tube one, the location nut of fixed bull wheel is provided on the main shaft tube end of frame outside.Quick Release
Device includes that the sky for extending to the central spindle in extension, being equipped in the main shaft tube end of frame outside is equipped in spindle tube
Chamber, the spring being equipped in set central spindle in cavity are fixed with the button contacted with spring, in frame inside in the end of central spindle
Circular hole that extension two sides are equipped with is equipped with diameter in circular hole and is greater than Circularhole diameter and has part to expose to external ball,
And the conical surface annular recess being equipped in the central spindle of corresponding ball and circular hole position.Ball is set between central spindle and spindle tube,
Conical surface annular recess can accommodate ball.Ball is stuck on circular hole after being detached from conical surface annular recess, then the spindle tube is locked in
On fixed central siphon, bull wheel is installed on spindle tube；Into vehicle frame after the movement of side, ball is detached from circular hole and slides into the conical surface annular central spindle
In recess, then the spindle tube and fixed central siphon separate, and spindle tube takes out out of fixed central siphon, and the bull wheel is from spindle tube
On unload.
The utility model has the beneficial effects that having dismounting simply and easily effect.Due in use, push button, central spindle
It is displaced to vehicle frame side, spring is squeezed, and ball is detached from out of circular hole slides into conical surface annular recess.At this point, spindle tube and solid
Without mutually interlocking, spindle tube can take out dead axle pipe out of fixed central siphon, so complete the purpose of fast quick-detach bull wheel, realize
Dismount simply and easily effect.

Specific embodiment
Utility model is described in further detail with reference to the accompanying drawing.
As shown in figs. 1-7, a kind of Quick Release wheel construction, including fixation of the installation with perforation on the vehicle frame 1 of wheelchair two sides
Plate 2 is equipped with after perforation in fixed plate 2 and is fixed on the fixation central siphon 3 in fixed plate 2, in fixed central siphon 3 by nut
Equipped with after fixed central siphon 3 to the spindle tube 4 extended on the outside of vehicle frame 1, the bearing 5 being equipped on spindle tube 4, on bearing 5
The bull wheel 6 of wheelchair is installed, and is equipped with the interior device for quickly disassembling 7 being equipped on spindle tube 4.Be provided on 1 inside spindle tube 4 of vehicle frame with
The extension 8 of the one of spindle tube 4 is provided with the location nut 9 of fixed bull wheel 6 on 4 end of spindle tube in 1 outside of vehicle frame.Quick Release
Device 7 includes being equipped with extend to the central spindle 71 in extension 8, set in 4 end of spindle tube in 1 outside of vehicle frame in spindle tube 4
Some cavitys 72, are fixed in the end of central spindle 71 and contact with spring 73 spring 73 being equipped in set central spindle 71 in cavity 72
Button 74, be equipped on 8 two sides of extension of the inside of vehicle frame 1 circular hole 75, be equipped with diameter in circular hole 75 and be greater than circular hole 75
Diameter and the ball 76 for thering is part to expose to outside, and the taper-face ring being equipped in the central spindle 71 of corresponding ball 76 and circular hole position
Shape recess 77.Ball 76 is set between central spindle 71 and spindle tube 4, and conical surface annular recess 77 can accommodate ball 76.Ball 76 is de-
From being stuck on circular hole after conical surface annular recess 77, then the spindle tube 4 is locked on fixed central siphon 3, and bull wheel 6 is installed on main shaft
On pipe 4.Into vehicle frame 1 after the movement of side, ball 76 is detached from circular hole and slides into conical surface annular recess 77 central spindle 71, then the master
Central siphon 4 and fixed central siphon 3 separate, and spindle tube 4 takes out out of fixed central siphon 3, and the bull wheel 6 is unloaded from spindle tube 4.
In use, push button 74, central spindle 71 is displaced to 1 side of vehicle frame, and spring 73 is squeezed, and ball 76 is out of circular hole
It is detached from and slides into conical surface annular recess 77.At this point, spindle tube 4 is interlocked with fixed central siphon 3 without phase, spindle tube 4 can be from fixing axle
It is taken out in pipe 3, so completes the purpose of fast quick-detach bull wheel 6, realize dismounting simply and easily effect.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
