Abstract

The utility model relates to a ring-shaped cushion (1), the cross section of the ring-shaped cushion is U-shaped with thinner both sides and a thicker bottom, and a metal sheet (2) is arranged in the ring-shaped cushion (1). When installed between the inner and the outer tyre of a motor vehicle tyre, the utility model can prevent sharp objects on the road surfaces (such as stones, glass, iron nails, etc.) from puncturing the inner tyre and can overcome the damage against the inner tyre caused by the friction between the inner and the outer tyres. The utility model has the advantages of simple product structure, easy installation, preventing the tyre from being damaged and obvious safety effect.

Description

The automobile tyre safety pad

The utility model relates between a kind of cover tire that is installed in self-propelled vehicle and the inner tube of a tyre and the cast liner that can protect tire not to be damaged.

As everyone knows, the tire of self-propelled vehicle (comprising various automobiles, motor bike etc.) is made up of the inner tube of a tyre and the cover tire that are installed on the steel ring, because wheel will contact various complex road surfaces in the process of moving, be easy to be punctured and cause and damage even explosion by sharp thing such as sharp stone, iron nail, glass; Moreover also there is the phase mutual friction between the inside and outside tire and makes inner tube of a tyre breakage, bring very big inconvenience to driving.

The purpose of this utility model is, designs a kind of automobile tyre safety pad, and it is installed in the cover tire inner face, can avoid the inner tube of a tyre punctured by sharp thing, also can prevent to produce between the Tire ﹠ Tube friction and damage the inner tube of a tyre.

The technical solution of the utility model is, described automobile tyre safety is lined with the cast pad, and its constructional feature is, the cross-sectional plane of described cast pad is the thin and thicker U-shapeds in bottom in both sides, and is equipped with sheetmetal in the described pad.

Make below in conjunction with accompanying drawing and to further specify.

Description of drawings:

Fig. 1 is the positive TV structure of a kind of embodiment of the utility model;

Fig. 2 be among Fig. 1 A-A to sectional structure;

In the accompanying drawings, 1-cast pad, 2-sheetmetal.

By Fig. 1 and Fig. 2 as can be known, automobile tyre safety described in the utility model is lined with cast pad (1), its constructional feature is, the cross-sectional plane of described cast pad (1) (be among Fig. 1 A-A to section) is the both sides U-shaped (or approximate U-shaped) thicker than thin bottom part, this U-shaped is advisable at the cover tire inner face with liner well, and is equipped with sheetmetal (2) in the described pad (1).As a whole, sheetmetal (2) in fact also is the cast body (the two has respective shapes) that places cast pad (1).

Principle of design of the present utility model is, the described cast pad (1) of built-in metal sheet (2) is installed between the cover tire and the inner tube of a tyre of tire, its pad shaped design is for closing with the fine lining of cover tire inner face, then sheetmetal wherein (12) the sharp things such as external iron nail, stone wedge angle, glass of can effectively resisting puncture the inner tube of a tyre, if the inner face (one side that contacts with the inner tube of a tyre) of this cast pad (1) is made smooth surface, then can avoid friction between itself and the inner tube of a tyre to cause the breakage of the inner tube of a tyre; Thereby realized that the utility model can protect the effect of " safety pad " that the inner tube of a tyre do not damage.And the utility model can not produce any adverse effect to original tire.Shape of cross section of the present utility model (for example shown in Figure 2) is according to the true form of vehicle tyre (cover tire) and respective design is a criterion to adapt and to have no adverse effects with it promptly.

As known from the above, the utility model is a kind of automobile tyre safety pad, and it installs pad between the inside and outside pad of tire; can prevent effectively that the inner tube of a tyre from being punctured by sharp thing; the inner tube of a tyre that also can avoid the Tire ﹠ Tube friction to cause damages, and prevents the Tire ﹠ Tube explosion, plays the effect of protection tire safety.Can make the series of products that are applicable to various tires, the saving of labor, save time, save worry, safe, practical, be of wide application.

Embodiment: according to the utility model product of accompanying drawing and said structure, be used for homemade five sheep board motor cycle rear wheel 3.00-18 type tires, described pad (1) adopts the flexible high molecular material mould molding to make, the integral width in cross section shown in Figure 2 with highly be 6 centimetres, 4 millimeters of pad (1) bottom thickness, 0.03 millimeter of both sides upper top thickness, implant thickness and be 0.5～0.08 millimeter and the sheetmetal (2) of respective width is arranged, sheetmetal (2) material can adopt the stalloy of the trade mark of homemade 3J21 or 3J531.

Claims

1, a kind of automobile tyre safety pad has cast pad (1), it is characterized in that, the cross-sectional plane of described cast integral body (1) is two and approaches and the thicker U-shaped in bottom, and is equipped with sheetmetal (2) in the described cast pad (1).
