Abstract

The utility model provides a wheel assembled structure of carriage. A button drives a bayonet lock to move and to make the axle separate from a fastening mechanism; simultaneously, the wheel is slightly drawn outward to dissemble the wheel; at this time, the bayonet lock sets back due to the effect of the elastic force of the reset spring and forms the fastening state again. The fastening mechanism comprises a concave groove on the axle, a bayonet lock capable of extending into the notch, a reset spring and a button able to control the expanding and contracting of the bayonet lock. The bayonet lock is arranged in the casing outside the pipe spreader. A position hole is arranged in the position on the pipe spreader corresponding to the concave position on the axle. The bayonet lock faces against the position hole. The reset is positioned is between the bayonet lock and the casing. The button is connected with the bayonet lock. The utility model can fast and easily disassemble the wheel on the carriage frame.

Description

A kind of pushchair wheel mounting structure

Technical field

The utility model relates to a kind of pushchair wheel mounting structure.

Background technology

Pushchair product on the articles for children market is of all shapes and colors at present, the function Nover practical.But some father and mother feels that step is very loaded down with trivial details, loses time very much when collection, transportation pushchair.In removing vehicle tyres, feel especially to bother very much, not only consuming time but also require great effort, also be afraid of go-cart has been ruined.Therefore disperseed original just busy baby's father and mother's energy, brought many inconvenience to life.

Summary of the invention

In order to solve the above problems, the utility model has provided a kind of pushchair wheel mounting structure, and it is characterized in that: wheel is installed in rotation on the axletree, in the pipe spreader on the axletree insertion vehicle frame, is movably fastened mechanism's axle tree on the pipe spreader.Describedly be movably fastened the button that mechanism comprises that the groove on the axletree, the bayonet lock that can stretch into groove, retracing spring and may command bayonet lock are flexible.Bayonet lock is positioned at the outer housing of pipe spreader, and the groove location on the corresponding axletree of pipe spreader offers knock hole, and bayonet lock is over against this knock hole, and retracing spring is between bayonet lock and inner walls, and button is connected with bayonet lock.

Principle of work is: button drive bayonet lock moves and then makes axletree break away from snap fastener, wheel is outwards just gently drawn can tear wheel open simultaneously, and bayonet lock is influenced by retracing spring elastic force and sets back at this moment, forms fastening state.

The beneficial effects of the utility model are can be fast, the dismounting wheel for father and mother have saved the time, is a kind of go-cart wheel push button quick detach structure of time-saving and efficiency on the go-cart vehicle frame easily.And this push button quick detach structure also can be used for the supermarket go-cart, and other needs Luggage Cart etc. in the go-cart of dismounting, preservation.

Description of drawings

Fig. 1 is the structural representation of an embodiment of the utility model;

Fig. 2 is the part sectional view of Fig. 1.

Specific embodiment

As shown in Figure 1, 2, it is characterized in that: wheel 2 is installed in rotation on the axletree 6, in the pipe spreader 31 that axletree 6 inserts on the vehicle frame 3, is movably fastened mechanism's axle tree 6 on the pipe spreader 31.Be movably fastened the button 1 that mechanism comprises that the groove 61 on the axletree 6, the bayonet lock 5 that can stretch into groove 61, retracing spring 4 and may command bayonet lock 5 stretch.Bayonet lock 5 is positioned at the housing 8 outside the pipe spreader 31, and groove 61 positions on the pipe spreader 31 corresponding axletrees 6 offer knock hole 7, and bayonet lock 5 is over against this knock hole 7, and retracing spring 4 is between bayonet lock 5 and housing 8 inwalls, and button 1 is connected with bayonet lock 5.Button 1 drives bayonet lock 5 and moves and then make axletree 6 break away from snap fasteners during work, wheel 2 is outwards just gently drawn can tear wheel open simultaneously, and bayonet lock 5 was influenced by retracing spring 4 elastic force and set back the formation fastening state this moment.
