CN2262504Y - Protector for inflatable tyre tube - Google Patents

Abstract

The utility model relates to a protector which is used for preventing inflatable tyre tube from being punctured and formed by a sheet metal ring body with folding edges. The protecting ring can be installed between the outer arc-shaped top of a tyre tube and the inner surface of a cover tyre on various vehicles for preventing tyre tubes from be punctured by sharp objects. Simultaneously, the normal running of vehicles can not be affected. The utility model has active effects on the safe and high-efficient running of vehicles.

Description

The inflatable inner tube fender guard

The utility model relates to tire technology, particularly a kind of anti-device of stabbing of tire.

The air-inflation tyre of being made up of inside and outside tire is widely used on the various vehicles; vehicle in the middle of travelling, tire through regular meeting by the ground sharp object puncture gas leakage and cast anchor, especially can't carry the bicycle of Das Reserverad; vehicles such as motor bike, it is very difficult to recover on the spot to travel.To how protecting inflatable inner tube to be punctured the technology and the product of gas leakage, do not finding as yet on the market with on the relevant publication at present.

The purpose of this utility model provides a kind of fender guard that prevents that inflatable inner tube is punctured.

For achieving the above object, the scheme that the utility model adopts is: size and shape that the size of a lateral surface and shape and cover tire inboard end face are installed between the outer arc end face that bears road surface pressure at inflatable inner tube and the medial surface of cover tire are corresponding, the circle body made from the elastic metallic thin plate, to stop that sharp object punctures the inner tube of a tyre, for the fracture that prevents the circle body both sides is cut the inner tube of a tyre, the two edges of circle body are converted into folded limit structure, make the steel ring fracture be folded to the outer side of circle.

The utility model compared with prior art owing at the inner tube of a tyre outer arc end face protection wire loop is housed, can play barrier effect to sharp object, prevents that the inner tube of a tyre is punctured gas leakage; Because the back up ring is made by the elastic metallic thin plate, and is therefore little to the elasticity effect of tire, do not influence the normal use of tire.

The utility model is described in further detail below in conjunction with embodiment:

Fig. 1 is that the utility model is loaded on the sectional schematic diagram on the bike tyre.

Fig. 2 is the front view that is used for bicycle inflatable inner tube back up ring.

Fig. 3 is that part sectional view is looked on the left side of Fig. 2.

Fig. 4 is the partial enlarged view of Fig. 3.

Shown in Figure 1, the utility model circle body 2 is installed between the medial surface that inflatable inner tube 4 bears the arc end face of road surface pressure and cover tire 1.The size of circle body 2 is corresponding with the size and the shape of cover tire 1 inboard end face with shape, makes it to be in harmony to fit together, and the fracture of circle body 2 both sides is converted into folded edge 3 to the circle outside and can avoids fracture to cut the inner tube of a tyre 4.

Fig. 2, Fig. 3, Fig. 4 have represented the global shape and the structure of the foregoing description.

Claims (1)

1, a kind of inflatable inner tube fender guard is characterized in that: the size of the inboard end face of the size of lateral surface and shape and cover tire (1) and shape is corresponding, the circle body (2) made with the elastic metallic thin plate, there is the folded edge (3) that is folded to the circle outside its both sides.
