Abstract

The utility model discloses an aerating tool of tyre, comprising a casing tube (7), a valve (3) integrating with the casing tube (7) and a movable inside valve spanner (1) penetrating the casing tube (7) and the valve core. The aerating tool of tyre is characterized in that: the aerating tool of tyre also comprises a connecting device able to be in air-tight connection with the lower end of the casing tube (7) and the cranked tire valve respectively. The inside valve can be disassembled conveniently by adopting the utility model, and simultaneously the gas leakage in the process of inflation is avoided.

Description

The tire inflatable tool

Technical field

The utility model relates to a kind of tire inflatable tool.

Background technology

When automobile tyre inflation, at first to unload the valve inside of tire with the valve inside spanner, inflation refills after finishing, but the air pressure in the tire is very big at this moment, hindered the installation of valve inside, gas when next is installed in the tire can leak unavoidably, and tire pressure is descended, and has influenced the driving safety of automobile.

Summary of the invention

For addressing the above problem, the utility model proposes and a kind ofly both valve inside can be installed easily, avoid the tire inflatable tool of gas leakage in the tire simultaneously again.

A kind of tire inflatable tool, comprise sleeve pipe, the upper end of sleeve pipe and a valve link into an integrated entity, and are installed with a mobilizable valve inside spanner in sleeve pipe and spool, its special feature is, also comprises the attaching parts that its two ends can be respectively be tightly connected with sleeve pipe lower end and cranked tire valve.

Adopt both dismounting valve insides easily of the utility model, avoid the gas leakage that takes place in the gas replenishment process simultaneously.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the structural representation of connection pipe in the utility model (8).

The specific embodiment

Come the utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, the utility model comprises sleeve pipe 7 and the valve 3 that links into an integrated entity, and captives joint with an end of the valve seat of valve 3 in the upper end of its middle sleeve 7, is installed with a mobilizable valve inside spanner 1 in the spool of sleeve pipe 7 and valve 3.

As shown in Figure 2, also comprise an attaching parts, its two ends can be tightly connected with sleeve pipe 7 lower ends and cranked tire valve respectively, attaching parts specifically can be a clamp nut that is actively socketed on sleeve pipe 7 lower ends, it also can be a connection pipe 8, as shown in Figure 2, the two ends of connection pipe 8 can be tightly connected with sleeve pipe 7 lower ends and cranked tire valve respectively, connection pipe 8 has negative thread, sleeve pipe 7 lower ends have corresponding outside thread, the two ends of connection pipe 8 can be tightly connected with sleeve pipe 7 lower ends and cranked tire valve respectively by screw thread fit, the rotation direction of the screw thread that matches with sleeve pipe 7 and cranked tire valve respectively in this connection pipe 8 is opposite, when this connection pipe 8 of rotation, sleeve pipe 7 and cranked tire valve are screwed simultaneously or are unclamped, and the O-ring seals of airtight effect also can be housed in connection pipe 8.

As shown in Figure 1, at the other end of the valve seat of valve 3 a detouchable seal cover cap 2 is housed, specifically can adopts to be threaded, the middle part of sealing lid 2 has the hole of matching with valve inside spanner 1.

As shown in Figure 1, an air-pressure gauge that is communicated with valve core inside 4 is housed with detection wheel tire pressure at any time on the valve seat of valve 3.

As shown in Figure 1, a breather pipe 5 is housed also on the valve seat of valve 3, a control cock 6 is housed on breather pipe 5, exit when control cock 6 adopts check valve to can be used for adjusting tire pressure, adopt common valve to can be used as and be connected the usefulness of inflating with the air pump mouth.

When being inflation of tire, by clamp nut or connection pipe 8 sleeve pipe 7 and cranked tire valve are screwed earlier, screw off valve inside with valve inside spanner 1 then, open seal cover cap 2, take out valve inside and valve inside spanner 1, by the cavity in the spool of sleeve pipe 7 and valve 3 to inflation of tire, can understand tire pressure at any time by air-pressure gauge 4, also can regulate air pressure by 6 venting of the check valve in the breather pipe 5, (as control cock 6 adopt common valve then can directly open control cock 6 by air pump mouth and breather pipe 5 directly to inflation of tire, need not to open seal cover cap 2) finish after first shutoff valve 3, putting valve inside for then valve inside spanner 1 inserts in the spool, open the valve of valve 3 behind the screwing hermetic lid 2, load onto valve inside and can unclamp clamp nut or connection pipe 8, take off this device.
