Abstract

The utility model relates to a device for mounting or dismounting tyres of vehicles by using the motive power of the vehicles, which is composed of a sleeve barrel 1, a crowbar 2 and a reed guiding mechanism 3, wherein, the reed guiding mechanism comprises a concave guide rail 4, a reed device and a roller 10. When a screw nut are arranged or dismounted by the device, the tyre is jacked up by a jack, and the screw nut is sheathed with the sleeve barrel 1 and rotated obversely and reversely by the crowbar 2 when the car is started and the tyre is rotated obversely and reversely, so the purpose of dismounting and mounting the screw nut is achieved. The device for mounting or dismounting tyres has the advantages of simple structure, convenient operation and low labor intensity and ensures the driving safety. The utility model is an ideal device for mounting or dismounting tyres of vehicles in long-distance transport.

Description

The motor tire replacer

The utility model relates to a kind of motor tire replacer that utilizes automobile self power, is specially adapted in the long-distance running tire and has broken and carry out dismounting.

At present, motor tire is carried out the manpower dismantling devices that the instrument of dismounting is made up of air inflating machine for dismantling tyre, electronic removing machine and sleeve and crowbar; But air inflating machine for dismantling tyre and electronic removing machine all can not carry with car, though and the manpower dismantling devices can carry and carries out the dismounting tire, but in transit, tire has been broken in the time of will dismantling, and it is too tight or nut is stuck to run into lug nut, two people are difficult to take apart with joint efforts, so will ask the capable workman of tire patching to carry out dismounting, make the driver overtired like this, influence traffic safety, waste time, cause traffic jam.

The purpose of this utility model is to overcome above-mentioned defective, provides a kind of simple in structure, easy to carry, utilizes the motor tire replacer of automobile self power.

The technical solution of the utility model: replacer is to comprise cover letter and crowbar, and feature is that an end of crowbar is provided with a continuous convex reed guide rail mechanism; Its convex reed guide rail mechanism is made up of two rollers of spill guide rail, leaf arrangement and band connecting shaft; Leaf arrangement is to comprise convex reed, cutting ferrule, base plate and hinge; The convex reed is to link to each other by hinge with the left end of base plate, and the base plate right-hand member is provided with cutting ferrule, and its reed right-hand member stretches in the cutting ferrule; The convex reed is provided with the fixedly ring tube of crowbar, be that crowbar one end inserts in the sleeve rear end hole, the other end is fastened in the ring tube of convex reed, on the ring tube tightening screw and a pressure pointer is arranged, and erecting on the described base plate has one and the corresponding pressure scale plate of pressure pointer; Leaf arrangement is arranged between two rollers of band connecting shaft, and promptly base plate is to place on the connecting shaft of two rollers, and its two roller is arranged in the spill guide rail.

The principle of work of this replacer: be to utilize jack motor tire jack-up built on stilts, during remove a tyre, this replacer is placed on the ground before the wheel (before with the automobile headstock being, after the tailstock is, during the assembling tire, replacer is placed on the ground of tire back: the sleeve on the replacer entangles lug nut, start a car, put in first gear, wheel rotates forward, nut is lived by jacket casing, sleeve is fixed and can not be rotated by crowbar, forces the nut counter-rotating to reach the purpose that splits out nut, because the position of nut on tire is inclined to one side limit, so when tire was rotated further, crowbar relied on convex leaf arrangement upper roller to do in the spill guide rail and moves back and forth.Crowbar changes torsion into pressure, and reed is pressed down, and the pressure pointer is descending and point out number pressure on the pressure scale plate along with reed, reaches the fastening standard of pressure of regulation.

In sum, the utility model modern design, simple in structure, cheap, easy to use, utilize automobile self power to carry out the dismounting tire, alleviated labour intensity, can make big-and-middle-sized passenger and freight car quick changing of tire in the way of travelling, save time, guaranteed traffic safety, solved the trouble of chaufeur replacing spare tyre difficulty in the long-distance transport.It is a kind of desirable motor tire replacer.

Below in conjunction with accompanying drawing the technical solution of the utility model is described in detail.

Fig. 1 is a working state schematic representation of the present utility model;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is a left TV structure scheme drawing of the present utility model.

Referring to Fig. 1, Fig. 2 and Fig. 3, the motor tire replacer is to comprise sleeve 1 and crowbar 2, feature is that an end of crowbar 2 is provided with a continuous convex reed guide rail mechanism 3, and its convex reed guide rail mechanism 3 is made up of two rollers 10 of spill guide rail 4, leaf arrangement and band connecting shaft;

Described leaf arrangement is to comprise convex reed 8, cutting ferrule 9, base plate 11 and hinge 12, and described convex reed 8 is to link to each other by hinge 12 with the left end of base plate 11, and base plate 11 right-hand members are provided with cutting ferrule 9, and its reed 8 right-hand members stretch in the cutting ferrule 9.Convex reed 8 is provided with the fixedly ring tube 7 of crowbar 2, be that crowbar 2 one ends insert in the sleeve 1 back stomidium, the other end is fastened in the ring tube 7 of convex reed 8, on the ring tube 7 tightening screw 13 and a pressure pointer 5 is arranged, and erecting on the base plate 11 has one and pressure pointer 5 corresponding pressure scale plates 6.Leaf arrangement is arranged between two rollers 10 of band connecting shaft, and promptly base plate 11 is to place on the connecting shaft of two rollers, and its two roller 10 is arranged in the spill guide rail 4.

Working process of the present utility model: mode of operation is to entangle nut on the tire by sleeve 1, and crowbar 2 one ends insert in the sleeve 1 back stomidium, and the other end is fixed in the ring tube 7 of convex leaf arrangement; When remove a tyre, utilize jack that tire jack-up is unsettled, on the ground in replacer placement motor tire the place ahead (is the place ahead with the automobile headstock), start automobile, put in first gear, wheel rotates forward, lug nut is entangled by sleeve 1, sleeve 1 is forced the nut counter-rotating by crowbar 2 fixing can not rotations, and nut is taken apart.Because nut position on tire is in inclined to one side limit, so when tire is rotated further, crowbar 2 relies on the roller 10 on the convex leaf arrangement to do in spill guide rail 4 and moves back and forth, when the assembling tire, its principle is identical with the principle of remove a tyre, just the transposing of the position of this replacer, promptly is placed on the ground at motor tire rear (as shown in Figure 1), automobile is hung up reverse gear, the tire reversing just can be screwed nut.This replacer is that crowbar changes torsion into pressure, thereby convex reed 8 is pressed down, and the pressure pointer is descending and point out pressure data on the pressure scale plate 6 along with reed 8, reaches the fastening standard of regulation dismounting pressure.
