Abstract

The utility model relates to an anti-prick gasket for protecting a tyre. Presently, the tyre is always pricked by sharp foreign matters leading to gas leakage when various cars are on the run, and normal work is influenced. The utility model can effectively solve the problem, which is characterized in that a protective layer 1 is provided with a guard board 2 whose anterior end is a guard board head 3, the middle of the guard board 2 is provided with a groove 4 in which a convex column 5 is arranged, and a gasket 6 is inlaid in the groove 4 by penetrating through the convex column 5. The utility model has simple fabrication and good effect, and the utility model can be widely used for tyres for cars, motorcycles, tricycles, etc.

Description

Anti-prick gasket

A kind of anti-tie pad is used to protect the various inner tubes of a tyre.

At present, all kinds of air-inflation tyres are often had the foreign matter of acute angle in the process of moving and are stabbed gas leakage, influence normal operation.In order to prevent that the inner tube of a tyre from being pricked gas leakage, people find out many methods, but all can not settle the matter once and for all.The inventor once spent the patent (applying date: 880727 with regard to anti-tie pad application; Application number: 88209101.8; Authorize day: 890802), because this patented technology exists mould is required deficiencies such as surface of steel plate high, compression moulding is wrinkling easily, thereby do not drop into practical application.

The utility model is to develop to form on the basis of a last patented technology, and it can solve the inner tube of a tyre by the bundle problem by actv. evidence.

Fig. 1 is a planar view of the present utility model;

Fig. 2 is the section-drawing along Figure 1A-A direction.

The utility model is as shown in Figure 1: backplate 2 is arranged on the protective layer 1, and the front end of backplate 2 is backplate head 3, and there is a groove 4 centre of backplate 2, and projection 5 is arranged in the groove 4, and pad 6 passes projection 5 and is set in the groove 4.

Fig. 2 is along the section-drawing of Figure 1A-A direction, contrasts with Fig. 1, can clearly be seen that structure of the present utility model: backplate 2 is arranged on the protective cover 1, and the groove 4 of the centre of backplate 2 has projection 5 in the groove 4, and pad 6 is set in the groove 4.

The utility model manufacturing is simple, and is easy to use, can be used for tires such as automobile, motor bike, three-wheel vehicle.

Manufacturing of the present utility model, using method are as follows:

1, gets one and make protective cover with isometric rubber tape or the kiss-coating canvas belt of the inner tube of a tyre; 2, the material of backplate is a nylon, and projection, backplate head and backplate are one, but the backplate head is slightly thinner than backplate, and the making of this part is to use mould compression moulding; 3, the material of pad is a stainless steel sheet, has on the pad and the corresponding circular hole of projection, and this part forms with the mould compacting; 4, after above-mentioned parts are got all the ready, backplate is bonded on the protective cover with milky white adhesive.One secondary anti-tie pad needs some of sticking patch, in the time of sticking, the afterbody of last backplate will with back one backplate the backplate skull on, (noting: can not be stained with, otherwise can not be crooked free) herein.Then, the pad edge is attached in the groove of backplate.

The anti-tie pad of moulding is placed between the tyre and the inner tube of a tyre of vehicle, and inflation can be travelled.

Claims

A kind of anti-tie pad is used to protect various tires, and it is characterized in that has backplate 2 on the protective cover 1, and the front end of backplate 2 is a backplate head 3, and there is a groove 4 centre of backplate 2, and projection 5 is arranged in the groove 4, and pad 6 passes projection 5 and is set in the groove 4.
