Description

Technical Field

[0001] The utility model relates to automobile tire auxiliary component technology, in particular to a fast-charging assembled sealing ring. Background Art

[0002] Vacuum tires are tubeless pneumatic tires, also known as low-pressure tires and pneumatic tires. This type of tire has high elasticity and wear resistance, and has good adhesion and heat dissipation performance. It is different from traditional tires with inner tubes in that the tire is fixed to the wheel frame by the action of air pressure. There is no inner tube and cushioning belt, which reduces the friction and heat generated between the inner tube and the inner cavity of the tire. The air inside is in direct contact with the rim, and the heat can also be directly dissipated through the rim, which helps to reduce the temperature of the tire and extend its service life.

[0003] Under the existing technology, a vacuum tire is usually installed on the wheel hub first, and then a sealing ring of a fixed size is selected and sleeved on the outside of the wheel hub. The inner side of the sealing ring maintains a sliding sealing connection with the protrusion on the outside of the wheel hub, and then the bottom of the sealing ring is pressed against the outside of the tire, and then inflated. After inflation, the tire expands and pushes the sealing ring out of the wheel hub. However, because the size of the sealing ring is fixed, a large number of sealing rings of different sizes need to be reserved to meet the modification needs of tires of different sizes. As the air pump continuously injects air into the tire, the tire wall gradually expands and becomes tight, and the internal pressure rises steadily until it reaches a critical point. The tire wall suddenly undergoes a small and rapid deformation release under high pressure. When the tire is deformed and released, the sealing ring will move quickly with the tire, causing the sealing ring to collide with the wheel hub, resulting in damage to the sealing ring, affecting the sealing performance of the sealing ring.

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] Embodiment 1:

[0038] See also Figure 1 - Figure 7 , a quick-filling assembled sealing ring, comprising a plurality of supporting components 1;

[0039] A plurality of filling components 2, which are respectively installed on one side of the adjacent supporting components 1;

[0040] A plurality of connecting and fixing components 3 are respectively installed on one side of the adjacent supporting components 1 and are also located on one side of the filling component 2 .

[0041] The support assembly 1 includes an arc-shaped notch steel 11;

[0042] The rubber block 12 under the support plate is fixedly installed in the middle of the bottom of the arc-shaped notch steel 11;

[0043] The rubber block 13 on the support plate is fixedly mounted in the middle of the top of the arc-shaped notch steel 11;

[0044] The inner sealing plate 14 of the support plate is fixedly mounted on the inner side of the arc-shaped notch steel 11;

[0045] A plurality of L-shaped grooves 15 are symmetrically arranged outside the arc-shaped notch steel 11;

[0046] A plurality of slide grooves 16 are respectively provided on one side of the arc-shaped notch steel 11 away from the rubber block 12 under the support plate and the rubber block 13 on the support plate.

[0047] The specific implementation is as follows: the arc-shaped notch steel 11 serves as the main structure of the support component 1, the rubber block 12 under the support plate is used to enhance sealing and buffering, the rubber block 13 on the support plate is also used to enhance sealing and buffering, the sealing plate 14 on the inner side of the support plate ensures internal sealing, the L-shaped groove 15 is used to connect with the filling component 2, and the slide groove 16 provides an installation track for connecting the fixing component 3.

[0048] The filling assembly 2 comprises:

[0049] A filling connecting plate 21 is clamped to the inner wall of the L-shaped groove 15 formed by the adjacent arc-shaped notch steel 11;

[0050] The filling lower rubber block 22 is fixedly mounted on the bottom of the filling connecting plate 21 and is also located on one side of the bottom of the arc-shaped notch steel 11;

[0051] The filling rubber block 23 is fixedly mounted on the top of the filling connecting plate 21 and is also located on one side of the top of the arc-shaped notch steel 11;

[0052] The filling plate inner sealing plate 25 is fixedly installed on the inner side of the filling connecting plate 21 .

[0053] The specific implementation is as follows: the filling connecting plate 21 is designed with a clip-on structure that matches the L-shaped groove 15. The size of the clip-on structure of the filling connecting plate 21 is slightly smaller than the L-shaped groove 15, and the clip-on structure of the filling connecting plate 21 can move on the inner wall of the L-shaped groove 15 to ensure that it can be firmly installed between adjacent arc-shaped notch steels 11. The filling lower rubber block 22 fills the gap and provides additional sealing effect. The filling upper rubber block 23 works together with the filling lower rubber block 22 to enhance the sealing performance. The inner sealing plate 25 of the filling plate prevents air from penetrating from the inside of the filling component 2.

[0054] A plurality of through fixing holes 221 are formed at the four corners of the bottom of the filling lower rubber block 22, and a fixing bolt 222 is movably installed inside the through fixing hole 221. The filling lower rubber block 22 is fixedly connected to the bottom of the two adjacent arc-shaped notch steels 11 by a fixing bolt 222 installed inside the through fixing hole 221.

[0055] A plurality of upper rubber block through holes 231 are provided at the four corners around the top of the filling upper rubber block 23, and a second fixing bolt 232 is movably installed inside the upper rubber block through hole 231. The top of the adjacent arc-shaped notch steel 11 is fixedly connected to the bottom of the filling connecting plate 21 by the second fixing bolt 232, and a dust cap 24 is movably installed on the inner wall of the upper rubber block through hole 231. The dust cap 24 is also located outside the second fixing bolt 232, and the top of the dust cap 24 is in the same plane as the top of the filling upper rubber block 23.

[0056] The specific implementation is as follows: the filling lower rubber block 22 not only fills the bottom gap between the support components 1, but also realizes a firm connection with the adjacent arc-shaped notch steel 11 through the through fixing holes 221 opened at the four corners of the bottom thereof, and the fixing bolts 222 movably installed inside the through fixing holes 221 pass through the rubber block and the arc-shaped notch steel 11, and are tightened by nuts or other fastening devices, thereby realizing a firm fixation between the filling lower rubber block 22 and the arc-shaped notch steel 11, and the filling upper rubber block 23 and the filling lower rubber block 22 are both made of rubber, which can still maintain sealing during stretching and compression.

[0057] The filling upper rubber block 23 fills the top gap between the support components 1, and opens upper rubber block through holes 231 at the four corners of its top. The inner side of the upper rubber block through hole 231 is also movably installed with a fixing bolt 232, but this time the tightening function of the bolt is not limited to connecting the filling upper rubber block 23 and the arc-shaped notch steel 11, but also passes through the through hole at the bottom of the filling connecting plate 21 to firmly connect the top of the adjacent arc-shaped notch steel 11 with the bottom of the filling connecting plate 21. In order to prevent dust, dirt or other impurities from entering the upper rubber block through hole 231 and affecting the tightening effect of the bolt, the dust cap 24 is designed to be installed on the inner wall of the upper rubber block through hole 231 and is located on the outside of the fixing bolt 232. The top of the dust cap 24 is maintained in the same plane as the top of the filling upper rubber block 23, ensuring the flatness and sealing of the sealing ring.

[0058] The connection and fixing component 3 comprises:

[0059] A connecting slider 33 is slidably mounted inside the slide groove 16;

[0060] The connecting block 31 is movably mounted on the top of the connecting slider 33, and a connecting slideway 311 is formed through the top of the connecting block 31;

[0061] The outer side of the fixing bolt 32 is slidably mounted on the inner wall of the connecting slideway 311, and one end of the fixing bolt 32 is fixedly mounted on the outer side of the arc-shaped notch steel 11.

[0062] The specific implementation is as follows: the connecting slider 33 is designed with a shape and size that matches the slide groove 16 of the arc-shaped notch steel 11 in the support assembly 1. The connecting slider 33 is slidably installed on the inner side of the slide groove 16, allowing fine-tuning in the horizontal direction to adapt to slight deviations during installation or adjust the tightness of the sealing ring. The connecting block 31 is movably installed on the top of the connecting slider 33, and the two can be connected by bolts, pins or other fastening devices to ensure that the connecting block 31 can be rotated or fine-tuned to a certain extent relative to the connecting slider 33.

[0063] A connecting slideway 311 is provided through the top of the connecting block 31 to allow the fixing bolt 32 to slide in the horizontal direction, thereby further increasing the flexibility and adaptability of the connection.

[0064] The outer side of the fixing bolt 32 is slidably mounted on the inner wall of the connecting slideway 311 of the connecting block 31, which means that the bolt can not only slide horizontally in the connecting slideway 311, but also tighten or loosen the connection by rotating the bolt.

[0065] One end of the bolt is fixedly installed on the outer side of the arc-shaped notch steel 11. By tightening the bolt, the connection block 31, the connection slider 33 and the adjacent support assembly 1 can be firmly connected together to form a stable and sealed structure.

[0066] Working principle: When the size of the sealing ring needs to be adjusted, the staff first inserts the filling connecting plate 21 into the slide groove 16, and then fixes the filling upper rubber block 23 to the top of the adjacent arc-shaped groove steel 11 through the fixing bolt 232, and then fixes the inner sealing plate 25 of the filling plate to the inner side of the filling connecting plate 21, and fixes the filling lower rubber block 22 to one side of the adjacent arc-shaped groove steel 11 through the fixing bolt 232. The inner diameter of the sealing ring can be adjusted by adjusting the tightness of the fixing bolt 32, and then tighten the fixing bolt 32.

[0067] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
