Description

Technical Field

[0001] The utility model belongs to the technical field of automobile inner tubes, in particular to an automobile inner tube capable of being deflated quickly. Background Art

[0002] Automobile inner tubes are commonly known as inner tubes. They are annular elastic tubes with tire valves used to maintain tire internal pressure. The valves are used to inflate and keep air at a certain pressure inside the inner tube. The inner tube should have good air tightness, heat resistance, elasticity, aging resistance and small permanent deformation. It is generally made of butyl rubber. The main properties of butyl rubber inner tubes are: butyl rubber inner tubes have good self-closing properties and high air tightness. The air pressure of the inner tube is above 8MPA after loading. The high air tightness of the tire body reduces natural gas leakage. The inflation frequency is lower than that of natural rubber inner tubes during use, and it is more fuel-efficient during driving.

[0003] For example, a Chinese patent with publication number CN214647389U discloses a car inner tube that can be deflated quickly. The patent connects an arc plate and a bracket through a first spring, and arranges a bellows between multiple arc plates to connect the inner tube to the vent pipe. The gas is released by turning the nut to reduce the pressure of the first spring, so that the first spring rebounds quickly to push the arc plate to squeeze the inner tube, so that the gas is discharged through multiple bellows and air columns. The bellows and vents are arranged to accelerate the flow of gas, and effectively avoid the disadvantage that the arc plate clamps the inner tube skin due to uneven force during movement, causing damage to the inner tube.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: using an arc plate to squeeze the inner tube to quickly discharge the air inside it, and the arc plate and the bracket are connected by multiple first springs, so that the bracket and the arc plate are in a movable state, and then when the bracket is in use, the bracket will be first affected by the vehicle transmission mechanism and rotate. At this time, since the first spring has a certain elastic deflection, the bracket may first drive the first spring to undergo elastic deformation when rotating, and then the bracket and the arc plate may not be easy to keep rotating at the same time, which may cause the air column and the bellows to become the first force-bearing members. After long-term use, the air column and the bellows may be deformed or damaged due to the rotation of the bracket, which may affect the use effect of the inner tube.

[0006] In view of this, we propose an automobile inner tube that can be deflated quickly. Summary of the invention

[0007] The utility model aims to provide an automobile inner tube that can be deflated quickly, so as to solve the problems raised in the above-mentioned background technology.

[0008] In view of this, the utility model provides an automobile inner tube capable of rapid deflation, comprising: an inner tube body, a mounting ring is arranged inside the inner tube body, a plurality of pressure plates are fixedly mounted on the inner circular wall surface of the inner tube body, an air pipe is fixedly mounted on the inner circular wall surface of the inner tube body, the air pipe passes through the pressure plate and the mounting ring, and a valve core is fixedly sleeved on the inner circular wall surface of the air pipe;

[0012] In the present technical solution, when the staff uses the valve core to deflate the inner tube body, as the internal air pressure of the inner tube body decreases, the pressure on the multiple pressure plates also decreases. At this time, the rebound force of the multiple springs will push the multiple pressure plates to squeeze the inner tube body, thereby accelerating the discharge speed of the gas inside the inner tube body. At the same time, when the multiple pressure plates push the inner wall of the inner tube body to move, the multiple first mounting shells will move with the movement of the inner tube body, and then the first slider will slide inside the first mounting shell, and then the multiple auxiliary deflation components will release the gas inside the inner tube body at the same time, thereby improving the inner tube body. The speed of the inner tube body being deflated is such that when the inner tube body is in use, the mounting ring will rotate due to the influence of the automobile transmission mechanism, and then when the mounting ring rotates, the mounting ring will drive multiple first sliders on its surface to rotate, and then the rotating first sliders will drive multiple first mounting shells and the inner tube body to rotate together, so that during the rotation of the mounting ring, due to the sliding cooperation of the multiple first sliders and the first mounting shells, the inner tube body will rotate along with it when the mounting ring rotates, thereby achieving the effect of quickly deflation of the inner tube body and ensuring that the inner tube body and the mounting ring rotate at the same time when in use.

[0013] In the above technical solution, further, the auxiliary deflation component includes:

[0014] An air guide hole is provided on one side of the first mounting shell, a first mounting hole is provided on one side of the first slider and the inner circular wall of the mounting ring, and a conduit is fixedly installed inside the first mounting hole.

[0015] In the present technical solution, when the first slider slides inside the first mounting shell, the air guide hole blocked by the first slider will be opened, and then the gas inside the inner tube body will enter the first mounting shell, and then the gas inside the first mounting shell will be discharged through the conduit, so as to assist in deflating the inner tube body when it is deflated, thereby facilitating the increase of the deflation speed of the inner tube body.

[0016] In the above technical solution, further, a sealing gasket is fixedly installed on one side of the first sliding block.

[0017] In this technical solution, air leakage between the first slider and the air guide hole is prevented.

[0024] The beneficial effects of the utility model are:

[0025] The automobile inner tube capable of rapid deflation, when deflated, as the air pressure inside the inner tube body decreases, the resilience of the multiple springs will push the multiple pressure plates to squeeze the inner tube body, thereby accelerating the discharge speed of the gas inside the inner tube body, and at the same time, the multiple first mounting shells will move as the inner tube body moves, and then the first slider will slide inside the first mounting shell, and then the multiple auxiliary deflation components will release the gas inside the inner tube body, thereby increasing the deflation speed of the inner tube body, and when the inner tube body is in use, due to the sliding cooperation of the multiple first sliders and the first mounting shell, the inner tube body will rotate together with the mounting ring when it rotates, thereby achieving the effect of rapid deflation of the inner tube body and ensuring that the inner tube body and the mounting ring rotate simultaneously when in use.
