Abstract

The utility model belongs to a wrench for an inflating tire, which is sheathed with a sleeve barrel (4) and a screw bolt (3) at the outer portion of the existing valve wrench (1). The sleeve barrel (4) is a Y-shaped tube, and a ventilating pipe port (5) is arranged on the sleeve barrel (4). The valve wrench (1) can be stretched and shrunk in the sleeve barrel (4). Additionally, a tire barometer (9) can be also added on the sleeve barrel (4), which is convenient for knowing air pressure in a tire in time. The utility model has simple structure and easy fabrication, not only reserve the advantages of the existing valve spanner, but also overcomes the defects of the prior art. The air valve of the tire can be flexibly disassembled and assembled by utilizing the utility model, and the utility model can also conveniently inflate and deflate the tire. Thereby, the work efficiency is improved.

Description

Wrench for inflating tyre

The utility model relates to a kind of tyre wrench, specifically belongs to use spanner when charging and discharging gas to tire.

At present; people are when charging and discharging gas to tire; all be with hand or valve key mounting or dismounting valve inside; especially in the time of need loading onto valve inside when finishing to tire inflation; because at this moment the tire internal gas pressure is bigger, usually the valve inside top can be flown, at this moment; people tend to be difficult to find outbound valve inside again, therefore influence normal work.Particularly also can take place sometimes because of valve inside collapses the accident that flies to cause people's injures and deaths, charge and discharge not only difficulty of gas, the effort of mistaking, but also can threaten to personal safety.

The purpose of this utility model is to remedy above-mentioned technical deficiency, designs a kind of tyre valve core of dismounting flexibly, thereby conveniently charges and discharge the combination wrench of gas to tire.

Fig. 1 is a structural representation of the present utility model.

This kind Wrench for inflating tyre is done to replenish improvement and is got existing valve spanner (1), it is characterized in that The outside of the existing lower end of valve spanner (1) adds sleeved (4) and bolt (3), and sleeve (4) is " Y " shape pipe, its Interior silk (7) and (8) has been pulled out respectively at pipe inwall two ends, and sleeve pipe (4) is provided with the ventilation mouth of pipe (5), can supply with tire and fill Connect during gas gas tube with or tire when venting do the gas outlet; One end of sleeve (4) and bolt (3) join bolt (3) hitching post (10) is hollow tubular, and the bottom of valve spanner (1) is that an end at bayonet socket (11) place inserts since then In the sleeve (4), bolt (3) has outer silk (6) with the end that sleeve (4) joins. Peace when connecing should be on bolt (3) Install sealing ring (2) additional on the outer silk (6), to guarantee sealing of the present utility model, in addition also can be in sleeve (4) On install tire gauge (9) additional, in order in time understand the atmospheric pressure value in the tire.

When the utility model uses, draw back valve key (1) in the pipe earlier, with the bottom of sleeve (4) is that this end at internal thread (7) place is placed on the valve inside of tire, again valve key (1) is advanced downwards and block valve inside, valve inside on the tire is unloaded, just can discharge the gas in the tire this moment, inflate to tire as need, at this moment just can on the ventilation mouth of pipe, set up the gas tube of aerating device, can inflate to tire, after filling required gas with, when promptly inflation finishes, be rotated down and advance valve key (1), the valve inside of screwing on gets final product.

The utlity model has simple in structurely, make easily, it has remedied the deficiency of prior art, utilize its not only dismounting tyre valve core flexibly, but also can charge and discharge gas to tire easily, and kept the advantage of former valve spanner, thus can significantly improve operating efficiency.

Claims
