Abstract

The utility model discloses a tire assistant device which comprises a bracket, a front wheel, two back wheels, a front locking plate and an upper slope plate; the front end of the bracket is fixed with a front fork while the front wheel is fixed on the front fork through a pin shaft, the front locking plate is connected actively on the front end of the bracket while the upper slope plate is an incline and two back wheels is jointed actively with the front end of the upper slope plate at two sides of the back end of the bracket through a pin. The tire assistant device can help the tire in making the vehicle continue to run when the tire is lack of gas and is very convenient and practical when the driver does not want to change the tire or is not convenient or cannot change the tire. The utility model can be folded in a non-state to be carried conveniently.

Description

Tyre auxiliary device

The utility model relates to a kind of auxiliary device of automobile tyre, specifically Tyre auxiliary device.

The tire blow-out of self-propelled vehicle often takes place, and at this moment just needs repairing or changes tire.Changing tire is the not only dirty but also tired work of part, especially in weather conditions than all the more so under the harsh conditions.If tire is forbidden to change in some place such as express highway, business district etc. just more bother, need trailer that self-propelled vehicle is dragged away.And chaufeur can not opened the self-propelled vehicle of the gas that has a flat tire and goes maintenance station to change tire.

The purpose of this utility model is to provide a kind of Tyre auxiliary device that can assist tire to make self-propelled vehicle continue to travel when the flat gas of tire.

For achieving the above object, Tyre auxiliary device of the present utility model comprises support, a front-wheel, two trailing wheels, preceding clamp and last ramps, the front end of described support is fixed with a front fork, described front-wheel is fixed on the described front fork by bearing pin, described before clamp be movably connected in described support front end above, the described ramp of going up is an inclined-plane, and described two trailing wheels are connected on the both sides of described back-end support with the described front end removable pin of going up ramp.

Above-mentioned Tyre auxiliary device, described support comprises front frame and after poppet, and described front frame and after poppet removable pin are connected together, and cut out a recess on described in the middle of the front end of ramp downwards, and described two trailing wheels are inserted respectively in the described groove of going up ramp recess both sides.

Above-mentioned Tyre auxiliary device is fixed with a stirrup between the two ends of described front frame.

Owing to adopted above-mentioned technical pattern, behind the flat gas of the tire of self-propelled vehicle, Tyre auxiliary device of the present utility model is placed the dead ahead of blow-out tire, and the tail end that will go up ramp is inserted under this blow-out tire, the driving machine motor-car makes it forward, at this moment blow-out tire is climbed up this Tyre auxiliary device gradually, reach along with its center of gravity, when it arrives Tyre auxiliary device middle, at this moment go up ramp and overturn forward, the rear end of preceding clamp then is subjected to the pressure of blow-out tire and turns over, blow-out tire just by preceding clamp and last ramp front and rear card tightly on Tyre auxiliary device, and Tyre auxiliary device before, trailing wheel can make self-propelled vehicle still can continue to move ahead, and repairs or replaces up to travelling to maintenance point.Therefore, this Tyre auxiliary device is not thought to change in person under the environmental conditions that tire, inconvenience maybe can not change tire at chaufeur and is seemed very convenient and practical.The mode of employing activity pin joint can make this Tyre auxiliary device energy folding under non-working condition between front frame and after poppet, and front-wheel is just in time inserted in the recess that cuts out in the middle of the upward slope front edge of board behind the folding, is easy to carry.Fixing stirrup not only can be strengthened the holding capacity of this Tyre auxiliary device on the front frame, also can carry hand simultaneously and use behind the Tyre auxiliary device folding.

Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model Tyre auxiliary device;

Fig. 2 is the structural representation of looking up corresponding to Fig. 1.

As shown in the figure, Tyre auxiliary device comprises front frame 1, after poppet 2, front-wheel 3, two trailing wheels 4, preceding clamps 5, goes up ramp 6, front frame 1 is a U-shaped steel pipe support, after poppet 2 is pair of parallel steel pipe supports, front frame 1 and after poppet 2 are connected together by connecting strap 71,72 and bearing pin 8 removable pins that weld on its two ends, 71 of two connecting straps of front frame 1 also are fixed with a stirrup 13, and it plays the effect of carrying hand simultaneously again.The front end of front frame 1 is fixed with a front fork 9, and front-wheel 3 is fixed on the front fork 9 by bearing pin 8, and preceding clamp 5 is fixedly coupled sheet 74, bearing pin 8 and nut 10 and is movably connected in above front frame 1 front end by being fixedly coupled sheet 73 and front frame 1 front end on it.Last ramp 6 is inclined-planes, in the middle of the front end of last ramp 6, cut out a recess 11 downwards, two trailing wheels 4 are inserted respectively in the groove 12 of recess both sides, and two trailing wheels 4 are reinstated the front end both sides that two bearing pin 8 removable pins are connected on after poppet 2 with two grooves 12 1 of last ramp 6 respectively.Front-wheel 3 and two trailing wheels 4 are steel wheel, all are covered with polyamine ester layer on its excircle.

On the outside face of preceding clamp 5 and last ramp 6, can stamp out some projectioies, having strengthened intensity, and make it get flat tire card tighter.
