The present invention relates to a tyre repair tool of vehicle. More specifically, the present invention relations to a sealant bottle for tyre repair of vehicle.
In the prior art, sealant in the sealant bottle is often pressed into a tyre under the action of the air produced by an air compressor in the process of tyre repair. After that, in order to achieve the tyre repair, the sealant can cover the inner wall of the tyre evenly while the vehicle is forwarding slowly. However, since the sealant hose inside the sealant bottle is commonly the one with smaller specific gravity, when the sealant bottle is positioned horizontally, the sealant therein cannot be fully utilized frequently. Regarding this problem, if some materials with greater specific gravity are used to make the sealant hose, its hardness is also enhanced simultaneously, in which case the sealant hose cannot bend flexibly inside the sealant bottle, whereby the sealant at the bottom side of the bottle body cannot be utilized fully either.
The objective of the present invention is to provide a sealant bottle for tyre repair of vehicle of which the sealant hose can bend flexibly inside the bottle body and abut against the bottom side of the bottle body all the time, aiming at the problems that the sealant inside the bottle cannot be fully utilized when the sealant bottle is positioned horizontally in the prior art.
According to an aspect of the present invention, a sealant bottle for tyre repair of vehicle is provided, which comprises a bottle body for holding sealant and a sealant hose arranged within the bottle body. A first bottle cap and a second bottle cap are disposed at an opening for outputting sealant of the bottle body, wherein the first bottle cap completely surrounds the second bottle cap, and the latter can slide within the former. The sealant within the bottle body is led out by combination of the sealant hose and a connection tube of sealant bottle passing through the second bottle cap.
The sealant hose is connected with a one-way valve at its one end. The one-way valve includes a valve body, a sealing plug and a valve cover, while the valve cover is arranged at one end of the valve body that is far away from the sealant hose. The valve body is arranged with a channel and a groove for guiding the sealant inside, wherein the latter connected to the channel is arranged at one end of the channel that is far away from the valve cover. Herein, the sealing plug is arranged in the channel and it can move therein along the axial direction of the bottle body. The one-way valve is arranged with a gravitational shell which surrounds the one-way valve.
In the above-mentioned sealant bottle for tyre repair of vehicle, the connection tube of sealant bottle is comprised of a second tube section arranged along the axial direction of the bottle body and a first tube section perpendicular to the second tube section. The second tube section passes through the second bottle cap and further connects with the sealant hose.
In the above-mentioned sealant bottle for tyre repair of vehicle, the second tube section of the connection tube of sealant bottle is provided with a retaining ring for preventing the connection tube of sealant bottle from loosening towards the outside of the bottle body in the sliding process.
In the above-mentioned sealant bottle for tyre repair of vehicle, the second bottle cap comprises a bottle cap body and a central channel arranged at the centre of the bottle cap body.
In the above-mentioned sealant bottle for tyre repair of vehicle, the central channel is inserted into the opening for outputting sealant of the bottle body. The inner surface of the bottle cap body is provided with internal threads, while the opening for outputting sealant of the bottle body is provided with external threads; wherein the internal threads are matched and connected with the external threads.
In the above-mentioned sealant bottle for tyre repair of vehicle, the gravitational shell is in threaded connection with the one-way valve.
In the above-mentioned sealant bottle for tyre repair of vehicle, the gravitational shell is connected with the sealant hose by a joint nozzle protruding from the end of the gravitational shell.
In the above-mentioned sealant bottle for tyre repair of vehicle, the inner diameter of the channel of the valve body is equal to the outer diameter of the sealing plug.
In the above-mentioned sealant bottle for tyre repair of vehicle, an end plate of the valve cover is provided with three projections. These projections are inserted into the corresponding slots at one end of the valve body that is far away from the sealant hose, so that the valve cover is connected with the valve body.
In the above-mentioned sealant bottle for tyre repair of vehicle, the bottle body also comprises an air inlet end. An opening for inputting air at the air inlet end of the bottle body is provided with a bottle stopper, while a sealing washer is further arranged between the bottle stopper and the opening for inputting air so as to prevent the leakage of the sealant.
When implementing the sealant bottle for tyre repair of vehicle of the present invention, the following advantageous effects can be obtained: the first bottle cap at the opening for outputting sealant of the bottle body is connected with the connection tube of sealant bottle, in which case the first bottle cap and the connection tube of sealant bottle can be turned collectively without turning the bottle body during the usage of the sealant bottle, thereby achieving a retractable application of the first bottle cap. Since the gravitational shell arranged at the end of the sealant hose has greater specific gravity, no matter the sealant bottle is positioned horizontally or vertically, the sealant hose can bend flexibly inside the bottle body and its end abuts against the bottom side of the bottle body all the time, so that the sealant inside the bottle body can be fully utilized. In the present invention, the one-way valve is a plug type one. It can be feedthrough smoothly for outputting the sealant under the action of air pressure, while it can seal the sealant hose very well so as to prevent the leakage of the sealant when it is unneeded to use the sealant bottle. All in all, the sealant bottle for tyre repair of the present invention is simple in structure, convenient in usage and capable of achieving a full utilization of the sealant therein.
The present invention will be further illustrated in detail with reference to accompanying drawings and specific embodiments. In the figures:

In addition, the bottle body 1 of the sealant bottle for tyre repair of vehicle also comprises an air inlet end in the present invention, at which an opening for inputting air is provided with a bottle stopper 9. In order to ensure a full sealing of the bottle body and to prevent the sealant from leakage in the unused state, a sealing washer is further arranged between the bottle stopper 9 and the opening for inputting air.
In the present invention, the working process by the cooperation of the sealant bottle for tyre repair and the air compressor is illustrated briefly as follows: (1) when the sealant bottle for tyre repair is unused, the bottle stopper 9 seals the air inlet end, and the sealing plug 53 abuts against the valve cover 52 to block the opening of the valve body 51 so that the bottle body 1 is sealed (
The gravitational shell 7 is one of the key points of the present invention. It can be made from a variety of materials with great specific gravity, such as iron, steel and varieties of alloy. As shown in
The purpose of the gravitational shell 7 is to increase the specific gravity of the end of the sealant hose 2. In the case that the sealant hose 2 is a flexible one, no matter how the sealant bottle for tyre repair is positioned, the end of the sealant hose 2 abuts against the bottom side of the bottle body 1 all the time so as to ensure a full utilization of the sealant inside the bottle body 1. The size of the gravitational shell 7 can be set according to actual needs. As shown in
