Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a tire facilitating the disassembly of an inner tube. Background Technique

[0002] During the use of bicycles, electric vehicles, and motorcycles, flat tires often occur. When the inner tube of the wheel needs to be replaced, the wheel has to be removed for replacement, which is very cumbersome, with low repair efficiency and long repair time.

[0003] An inner tube facilitating disassembly described in a patent document with the patent publication number CN207684999U includes a tire body and an air nozzle provided on the tire body. The tire body is a split structure. The tire body includes two open free ends, and the two free ends are respectively provided with shaping caps for sealing. The free ends are hermetically connected to the shaping caps. The air nozzle is inserted into the air nozzle hole on the wheel hub, and the inner tube is fixed on the wheel hub along the circumference of the wheel hub. The two shaping caps are in contact connection, and then a protective cover is sleeved on the two shaping caps to protect the two shaping caps in the protective cover. The design is ingenious, which can fundamentally solve the problem of inconvenient disassembly of replacing the inner tube and avoid the jolting of the vehicle body during later use.

[0004] However, this device has deficiencies in use. During the process of using the shaping cap to drive the free end to fix the inner tube on the inner wall of the outer tire, since both the inner tube and the outer tire are made of rubber and there is no structure for fixing the inner tube in the outer tire, when the tire rotates at high speed, the inner tube will slide along the inner wall of the outer tire, causing the inner tube to be squeezed and deformed, and the pressure on some positions of the inner tube is too large, thereby greatly reducing the service life of the tire.

[0005] Based on this, a tire facilitating the disassembly of an inner tube is now provided, which can eliminate the drawbacks of the existing device. Content of the Utility Model

Specific implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0026] In one embodiment, as Figure 1 and Figure 4 shown, a tire facilitating the disassembly of the inner tube includes an outer tire 100, an inner tube 300 is disposed in cooperation with the inner wall of the outer tire 100, an air filling assembly is disposed at the bottom of the inner wall of the outer tire 100, and the right side of the air filling assembly is connected to the inner tube 300 through a fixed-end assembly, and the inner tube 300 can be filled with air through the air filling assembly.

[0027] In one embodiment, as Figure 2 and Figure 3 shown, the air filling assembly includes an air storage chamber 200 embedded in the inner wall of the outer tire 100, a valve core 201 is disposed at the top end of the air storage chamber 200, a through air filling installation hole 202 is disposed on the right side of the air storage chamber 200, and the arrangement of the air filling installation hole 202 can transfer the gas temporarily stored in the air storage chamber 200 to the inner tube 300; a set of symmetrical anti-slip grooves 203 are disposed on the left and right sides of the air storage chamber 200, and a plurality of semi-circular grooves 204 distributed in a circumferential array are disposed outside the anti-slip grooves 203, and the arrangements of the anti-slip grooves 203 and the semi-circular grooves 204 reserve space for the fixation of the inner tube 300.

[0028] In one embodiment, as Figure 3 shown, an installation hole is disposed at the top end of the air storage chamber 200, and the valve core 201 is clamped on the air storage chamber 200 through the installation hole, and the gas can be temporarily stored in the air storage chamber 200 through the valve core 201; the air storage chamber 200 is made of rubber material to prevent damage to the inner tube 300 due to too hard texture.

[0029] In one embodiment, as Figure 5As shown, the fixed-end assembly includes a fixed platform 400, a fixed block 401, an air-supplementing column 402, an annular fixed block 403, and an anti-slip protrusion 404. A through air-supplementing column 402 is provided at the middle position of the fixed platform 400. The air-supplementing column 402 can send the air storage chamber 200 into the inner tube 300. A fixed block 401 is provided on the outer surface of the air-supplementing column 402, which plays a fixing role when the air-supplementing column 402 extends into the inner wall of the air storage chamber 200. An annular fixed block 403 is provided at one end of the air-supplementing column 402 away from the fixed platform 400, which is used to fill the gap between the fixed platform 400 and the anti-slip groove 203, so that the air-supplementing column 402 can be more firmly fixed in the air-supplementing installation hole 202. A plurality of anti-slip protrusions 404 are also provided on the side surface of the fixed platform 400, which further fixes the inner tube 300 through cooperation with the semi-circular groove 204.

[0030] In this embodiment, by inserting the air-supplementing column 402 into the air-supplementing installation hole 202 and simultaneously rotating the fixed platform 400 to align the positions between the anti-slip protrusion 404 and the semi-circular groove 204, the inner tube 300 and the air-supplementing assembly can be connected.

[0031] In one embodiment, as Figure 5 shown, the fixed block 401 is also connected to the upper surface of the fixed platform 400, reducing the gap between the air-supplementing column 402 and the air-supplementing installation hole 202, so that during the movement of the air-supplementing column 402 with the tire, it will not be disconnected from the air-supplementing installation hole 202 due to the existence of the gap. The size of the annular fixed block 403 matches that of the air-supplementing installation hole 202. The annular fixed block 403 is made of elastic rubber material and can be deformed under force extrusion, and then fixed in the air-supplementing installation hole 202. The size of the anti-slip protrusion 404 matches that of the semi-circular groove 204. Through the settings of the anti-slip protrusion 404 and the semi-circular groove 204, the contact area and friction between the fixed platform 400 and the anti-slip groove 203 are increased. At the same time, the setting of the special-shaped hole groove makes the inner tube 300 less likely to be misaligned.

[0032] In one embodiment, as Figure 3 and Figure 5 shown, the fixed platform 400, the fixed block 401, the air-supplementing column 402, the annular fixed block 403, and the anti-slip protrusion 404 are all made of rubber material, which is conducive to the soft connection between the inner and outer tires and avoids the hard texture of the fixed-end assembly from damaging the tire.

[0033] In one embodiment, as Figure 4 shown, one end of the inner tube 300 is provided with a fixed-end assembly; the other end of the inner tube 300 is provided with a fixed platform 400.

[0034] In this embodiment, by aligning the anti-slip protrusions 404 on the outer side of the fixed platform 400 with the semi-circular grooves 204, both ends of the inner tube 300 are fixed to the inner wall of the outer tube 100. A fixed-end component is provided at one end, and a fixed platform 400 is provided at the other end, so as to supplement air into the inner tube 300 unidirectionally, making the structure simpler and the process of disassembly and installation more convenient.

[0035] In one embodiment, as Figure 1 shown, a separating agent is also coated between the inner tube 300 and the outer tube 100, which can better isolate the inner and outer tubes, reduce the friction between the inner tube 300 and the outer tube 100, and make the disassembly of the inner tube more convenient.

[0036] Working principle: When installing the tire, insert the air supplement column 402 on the inner tube 300 into the air supplement installation hole 202, and align the anti-slip protrusions 404 at both ends of the inner tube 300 with the semi-circular grooves 204 to complete the preliminary fixation of the inner and outer tubes. Then, supplement air into the inner tube 300 through the air supplement component to make the inner tube 300 fit with the outer tube 100. When it is necessary to remove the outer tube, first deflate the inner tube 300 through the valve core 201 in the air supplement component, and then hold one end of the inner tube 300 provided with the fixed-end component and pull it out in the direction away from the air storage chamber 200. Since the annular fixing block 403 is made of elastic rubber material and deforms under force, the inner tube 300 is separated from the air storage chamber 200.

[0037] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
