Description

  The present invention relates to a vehicle tire repair tool, and more particularly to a vehicle tire repair sealant bottle.

In the prior art, the sealant inside the sealant bottle is pressed into the tire under the action of air generated by an air compressor during the tire repair process. Thereafter, the sealant uniformly covers the inner wall of the tire while the vehicle slowly travels, and the tire repair is completed.
However, since the specific gravity of the sealant hose inside the sealant bottle is usually small, when the sealant bottle is placed horizontally, the sealant inside the sealant bottle often becomes unusable.
Regarding this problem, even if you try to make a sealant hose with a material with a larger specific gravity, the hardness will increase at the same time, so the sealant hose will not bend flexibly inside the sealant bottle, and the sealant is left behind on the bottom side of the bottle body. I can do it.

  The purpose of the present invention is to focus on the problem that when the sealant bottle is placed horizontally, the sealant in the bottle cannot be left over. The sealant hose bends flexibly inside the bottle body and always touches the bottom of the bottle body. The object is to provide a sealant bottle for repairing a tire of a vehicle.

A sealing washer is provided between the bottle stopper 9 and the air input opening to ensure sealing of the bottle body and to prevent leakage of the sealant when not in use.

Hereinafter, the operation process by the combination of the sealant bottle and the air compressor for tire repair in the present invention will be briefly described.
(1) When the sealant bottle for tire repair is not used, the bottle stopper 9 seals the air inlet end, the sealing plug 53 contacts the valve lid 52, and blocks the opening of the valve body 51; The bottle body 1 is sealed (FIG. 3).
(2) When the air compressor starts and air is input and the pressure rises to a certain value (2-4 bar), the bottle stopper 9 is pressurized and opened, and the air enters the bottle body 1 and the inside Lead to high pressure environment.
(3) The sealing plug 53 of the one-way valve is acted on by the high-pressure air inside the bottle body 1 and does not come into contact with the valve lid 52. In this case, the sealant enters the sealant hose 2 through the one-way valve and flows out of the bottle body 1 through the connection pipe of the sealant bottle (FIG. 4).

The gravity shell 7 is one of the main points of the present invention.
It is made from a variety of materials with a large specific gravity such as iron, steel and various alloys.
As shown in FIG. 2, the gravity shell 7 of the present invention has a hollow cylindrical structure and covers the periphery of the one-way valve. A thread is provided on the inner surface of one end of the gravity shell 7 and a protruding coupling nozzle 71 is formed on the other end.
The thread is used for screwing with the valve body 51, and the coupling nozzle 71 is fitted into the sealant hose 2 and coupled with the sealant hose 2.

The purpose of the gravity shell 7 is to increase the specific gravity of the end of the sealant hose 2.
When the sealant hose 2 is flexible, the end of the sealant hose 2 always abuts against the bottom side of the bottle body 1 regardless of how the sealant bottle for tire repair is placed. Can be used without leaving any sealant.
The dimensions of the gravity shell 7 are set according to actual needs. As shown in FIG. 1, the gravity shell 7 completely surrounds the one-way valve, but in other embodiments it may only surround a portion of the one-way valve.

Further, as shown in FIG. 2, the one-way valve includes a valve body 51, a valve lid 52, and a sealing plug 53.
The end plate of the valve lid 52 is provided with three protrusions 521.
These protrusions 521 are fitted into corresponding slots 512 at one end of the valve body 51 away from the sealant hose 2, and the valve lid 52 is firmly coupled to the valve body 51.
In addition, a seal ring 54 is provided between the valve lid 52 and the valve body 51 to ensure a sealing connection between them.
Of course, the coupling between the valve body 51 and the valve lid 52 is not limited to the method shown in the figure.
In another embodiment, an adhesive means can be used for coupling the valve body 51 and the valve lid 52.

2 to 4, a channel is formed inside the valve body 51, through which the sealant enters the sealant hose 2.
In the sealed state, the sealing plug 53 is disposed in contact with the valve body 51 and the valve lid 52 to block the inlet portion of the channel and prevent the sealant from entering the channel (see FIG. 3).
A sealant guide groove 511 connected to the channel is provided at one end of the channel away from the valve lid 52. The sealing plug 53 slides in the channel under the action of high pressure air until it reaches the end of the channel away from the valve lid 52 (shown in FIG. 4).
Here, the sealant flows through the channel and the sealant guide groove 511 into the sealant hose 2.
The inner diameter of the channel of the valve body 51 is equal to the outer diameter of the sealing plug 53.
Therefore, the sealing plug 53 abuts against the inner wall of the channel in a stationary state and a moving state, and ensures prevention of leakage of the sealant.
The sealing plug 53 used in the present invention is made of rubber, but can be made of other suitable materials.

At the same time, by providing the sealing plug 53, it is possible to keep the sealant stored at high and low temperatures.
Under the influence of the high and / or low temperature environment in which the sealant bottle is placed, the air and sealant inside the bottle expand and / or contract, resulting in a change in pressure across the bottle.
Prior art sealant bottle sealing devices are very prone to breakage due to these reasons, particularly the use of aluminum foil or film in the sealing device.
In the sealant bottle for repairing a tire of a vehicle according to the present invention, the channel inside the valve body 51 is provided with a slight movable space for the sealing plug 53, and the pressure change caused by the expansion and / or contraction of the air and the sealant is reduced. Remove appropriately.
During operation, the sealing plug 53 always abuts the channel wall, thus ensuring a sealing environment inside the entire sealant bottle.

As shown in FIG. 5, the second bottle cap 8 includes a bottle cap body 81 and a central channel 82 provided at the center of the bottle cap body 81.
The central channel 82 is inserted into the sealant output opening of the bottle body 1.

The two bottle caps are inserted and joined to each other, and the second bottle cap 8 slides in the first bottle cap 3.
With this structure, when the used sealant bottle is disassembled, the bottle cap of the sealant bottle can be expanded and contracted, thereby increasing the flexibility of the disassembling work.
As shown in FIG. 6, the second bottle cap 8 is completely inserted into the first bottle cap 3 in the non-stretched state.
Therefore, the first bottle cap 3 completely surrounds the second bottle cap 8 and approaches the bottle body.
In contrast, in the extended state (not shown), the first bottle cap 3 slides relative to the second bottle cap 8, and the distance from the bottle body 1 increases.
The connecting pipe of the sealant bottle rotates integrally with the first bottle cap 3.

In the vehicle tire repair sealant bottle described above, the connection pipe of the sealant bottle includes a second pipe portion 42 provided along the axial direction of the bottle body 1 and a first pipe portion perpendicular to the second pipe portion 42. 41 is included.
An external thread is provided on the outer surface of the first pipe portion 41 and is coupled to a sealant throat pipe for introducing a sealant into the tire.
