Abstract

Provided is a wheel-type flat tyre booster, which can reduce the difficulty in boosting flat tyres and prevents flat tyres being boosted from rolling depression. The wheel-type flat tyre booster mainly comprises a rack, a pin shaft, a tyre backing plate, a roller, a roller rack or a connecting rod. By the replacement of flat tyres with the roller which is capable of self-adaptive advancing direction adjustment, the great friction between rear parts of flat tyres and the ground are fundamentally eliminated, making the boosting smooth and avoiding damages of inner tyres caused by rolling depression. Components which are connected via the pin shaft can be placed in the rack in a directional rotating manner, so that no function is affected when the wheel-type flat tyre booster is in use, and the volume is minimized for easy carrying when the wheel-type flat tyre booster is not used.

Description

Wheeled flat tire booster

Technical field

The utility model relates to a kind of at the two-wheeled vehicle, and the light instrument of boosting behind the flat tire especially has good protective effect to tube tyre behind flat tire in the way of travelling.

Background technology

Because the two-wheeled vehicle are mainly based on cover tire+inner tube of a tyre or vacuum tyre at present, behind the escape of air in the tire, the driver is difficult to easily promote to move ahead, especially tire is with the user of cover tire+inner tube of a tyre, the hidden danger that also exists the inner tube of a tyre to be scrapped by roll extrusion loses more than gain thereby make originally simple maintenance cost become to enlarge indirectly after a large amount of muscle power of waste on the contrary.

Summary of the invention

In order to overcome the blank that does not have portable boosting instrument behind the flat tire of two-wheeled vehicle tires, the utility model provides a kind of wheeled flat tire booster, can make the driver easily promote vehicle and move ahead, and can relieved tire can be because of not lost efficacy by roll extrusion.

The technical scheme that its technical matters that solves the utility model adopts is: different according to urban highway and back road, but self regulate the roller that turns to 2 or 4, be fixed on the corresponding support by the axle ways of connecting, different according to every money vehicle hub external diameter and width, be free to regulate the tire backup plate, make it to mate different vehicles.Under the vehicle normal operating condition, can its volume be diminished rapidly by the orientation rotation, easily put into boot for standby.

A kind of wheeled flat tire booster, it is characterized in that: go up at support (6) and use bearing pin to connect tire backup plate (3), rolling wheel support (2) or pipe link (9), and make up with roller that only limits axial freedom (7) or roll wheel assembly (1), roller (7) can be followed the automatic adaptive adjusting travel direction of car on the ground, thereby opens and shrink and use and pack up in the mode of orientation rotation.

The beneficial effects of the utility model are: you are easily carried out behind the flat tire of vehicle, and can protect your tire can not lose efficacy because of roll extrusion in the case.

Description of drawings:

Come the utility model is further specified below by drawings and Examples

Fig. 1 is the detailed map of urban highway version of the present utility model

Wherein among Fig. 1: roll wheel assembly (1); Rolling wheel support (2); Tire backup plate (3); Bearing pin 1(4); Bearing pin 2(5); Support (6); A, B, C, D all represent the axle center of each turning cylinder degree of freedom; I, II are that amplify the part of Fig. 1.

Fig. 2 is the scheme drawing after Fig. 1 folds

Fig. 3 is the detailed map of urban and suburban roads version of the present utility model

Wherein among Fig. 3: roller (7); Rolling wheel support (8); Pipe link (9); Support (10); Tire backup plate (11); Bearing pin (12); E, F, G all represent the axle center of turning cylinder degree of freedom separately; III, IV are that amplify the part of Fig. 3.

Fig. 4 is the scheme drawing after Fig. 3 folds

The specific embodiment:

One: with the city version is example

Among Fig. 1: roll wheel assembly (1) itself has around the 360 degree rotations of A axle, can satisfy after making up with rolling wheel support (2) and self follow car adjusting travel direction on the ground; Rolling wheel support (2) is by bearing pin 1(4) be connected on the support (6), can do the rotation of limited angle after the connection around the B axle, spacing to open the back, I is amplified in the part of seeing for details among Fig. 1, and the effect that draw in the rotation back sees Fig. 2 for details; Tire backup plate (3) is by bearing pin 2(5 in addition) can go up the diverse location assembling at support (6), rely on bearing pin 1(4 then) location, satisfy different wheel external diameter demands and see the local II of amplification among Fig. 1 for details.

With product outward winding to Fig. 1 state as for ground, then that the car of flat tire is placed on it, just can freely carry out, because so flat tire is the danger that does not exist flat tire to be lost efficacy by roll extrusion that can not rotate, after the use its orientation is rotated to Fig. 2 effect, just can rapidly smaller volume easily be placed within the boot.

Two: with the rural area version is example

Among Fig. 3: can do 360 degree rotations around the D axle after roller (7) makes up with rolling wheel support (8), can do 360 degree rotations around the E axle after rolling wheel support (8) makes up with pipe link (9); Roller (7), rolling wheel support (8), pipe link (9) combination back are connected on the support (10) by bearing pin (12), rotate by the F axle.The effect that draw in the rotation back sees Fig. 4 for details; Tire backup plate (11) connects the rotation around axle F by bearing pin (12), reaches spacing and realize that the effect that supports tire sees the local IV of amplification of Fig. 3 for details on support (10); Because this money support (10) is so overhead very high all wheel diameters that almost are fit to.

With product outward winding to Fig. 3 state as for ground, then that the car of flat tire is placed on it, just can freely carry out, because so flat tire is the danger that does not exist flat tire to be lost efficacy by roll extrusion that can not rotate, after the use with its successively orientation rotate to Fig. 4 effect, just can rapidly smaller volume easily be placed within the boot.

Claims

1. wheeled flat tire booster, it is characterized in that: go up at support (6) and use bearing pin to connect tire backup plate (3), rolling wheel support (2) or pipe link (9), and make up with roller that only limits axial freedom (7) or roll wheel assembly (1), roller (7) can be followed the automatic adaptive adjusting travel direction of car on the ground, thereby opens and shrink and use and pack up in the mode of orientation rotation.
