Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, the utility model includes vehicle wheel frame 1, wheel 6, it also includes central siphon 7, racing lock fixed core 8, sky
Turn on pass 10；The center left of wheel 6 is provided with left axle sleeve 4, right side and is provided with right axle sleeve 12；The lower end of right axle sleeve 12 is provided with
Projection, is easily installed in dismounting.Left axle sleeve 4, the outside of right axle sleeve 12 are respectively arranged with revolver lid 5, right wheel lid 11；Revolver lid 5,
Right wheel lid 11 is respectively arranged on the wheel frame of the both sides of wheel 6.
Vehicle wheel frame 1 is set up on wheel and is connected by central siphon 7 with wheel；The two ends of vehicle wheel frame 1 are respectively arranged at a left side
The outside of wheel cap 5, right wheel lid 11.The level of central siphon 7 is placed through on vehicle wheel frame 1, left and right wheel cap and wheel.The two ends of central siphon 7 cover
It is equipped with outer shaft 3；The outside of outer shaft 3 is provided with locking nut 2, and the mouth of pipe of locking nut 2 against central siphon 7 is screwed into locking.
Elastic neck is provided with right wheel lid 11；Idle running switch 10 is inserted in elastic neck；The length of elastic neck is big
In the height of idle running switch 10, idle running switch 10 can be moved up and down along radial direction.Idle running switch 10 is internally provided with sky
Turn Lock spring 9；The upper end of idle running Lock spring 9 is provided with racing lock fixed core 8；The lower end of racing lock fixed core 8 is fixed on
