Abstract
The utility model discloses a puncture-preventing inner tube covered on the inner surface of a tyre cover of a tyre. The cross section of the utility model near the ground is in an arched shape. The utility model is characterized in that two ends of the arched shape are extended with steel ring parts, and the whole puncture-preventing inner tube is an unclosed circular ring. The utility model having the advantage of simple structure, low cost, repeated usage, convenient installation and operation is suitable for the tyres of various non-motor vehicles to effectively prevent the tyres from being punctured by different foreign matter and causing air leakage, and the problem puzzling riders is solved completely.
Description
The utility model belongs to the anti-technical field of stabbing of unpowered vehicle tire, particularly relates to a kind of anti-stamp inner tube that is overlying on the inner surface of cover tyre of tire.
At present, all kinds of unpowered vehicles in use, cover tire and ground contact friction are protruded into by cullet, bushel iron wood shavings, drawing pin and sharp rubble easily and cause the damaged gas leakage of the inner tube of a tyre.When meeting this situation, normal employing reaches the purpose of car inner tube of a tyre mending-leakage from valve inside pours into leakproof glue in tire mode.Other has a kind of method, when the car inner tube of a tyre is poked, adorns a small air pump at the axletree position in the process of promptly the riding process, or in the production process of the car inner tube of a tyre, be positioned at the valve inside place and adorn a small-sized rubber air pump, when rolling, constantly in tire, inflate, remedy and poke the gas that the position constantly leaks outside when wheel.More than these all are passive settling mode, also once the someone proposed a kind of active solution, promptly in the car cover tire, cover the anti-steel band that stabs of one deck, its cross section is arch, so still can't prevent to puncture the inner tube of a tyre from steel ring inside groove foreign material and steel wire and gong cap, when reaching the dismounting car wheel covering, the situation that dismantling devices scratches the inner tube of a tyre takes place.
The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, can make wheel in the cruising process, the anti-stamp inner tube that can not poked.
The technical solution of the utility model is: a kind of anti-stamp inner tube, and it closely is arch in the cross section of face portion, and its characteristics are: the arch two ends also extend to the steel ring part, and integral body is untight annular arrangement.
Owing to adopt such scheme, be not difficult to draw conclusion like this, the utility model is simple in structure, is skillfully constructed, and cost is low, but repeated use is easy to install and use, applicable to various unpowered vehicle tires, the industrial utilization of tool height.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is that the utility model is installed on the cross-sectional view in the tire.
Among the figure, inner tube 2 global sections are untight annular arrangement, and its ground proximity core is thicker, thickness is roughly 8 millimeters, then left, and to the even attenuation in both sides, it is the thinnest to press close to steel ring 4 parts, and inner tube 2 surfaces are carved and established netted decorative pattern, and integral body is made with tartan.Because of its external diameter and R radian are equal to the internal diameter and the R radian of cover tire 1, during use its liner is got final product between inner tube 3 and cover tire 1.
Claims (3)
1. prevent stabbing inner tube for one kind, it closely is arch in the cross section of face portion, it is characterized in that: the arch two ends also extend to the steel ring part, and integral body is untight annular arrangement.
2. by the described a kind of anti-stamp inner tube of claim 1, it is characterized in that: the inner tube of ground proximity core is thicker, and it is to the even attenuation in left and right both sides, and it is partly the thinnest to press close to steel ring.
