Description

Technical Field

[0001] This utility model relates to the field of tire assembly technology, specifically a three-way valve for tire assembly pipe connection. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, support the vehicle body, buffer external impacts, make contact with the road surface, and ensure the vehicle's driving performance.

[0003] Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing capacity, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flexural strength, as well as low rolling resistance and heat generation. Tires need to use a three-way valve to connect the pipeline during assembly. A three-way valve is a valve device with three ports, one inlet and two outlets. However, existing three-way valves usually connect to external pipelines through threads. Misalignment of the threads can easily lead to insufficient air tightness, affecting the use of the three-way valve. Utility Model Content

[0004] The purpose of this utility model is to provide a three-way valve for connecting pipes in tire assembly, in order to solve the problem mentioned in the background art that existing three-way valves are usually connected to external pipes by threads, and misalignment of the threads can easily lead to insufficient air tightness, affecting the use of the three-way valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-way valve for tire assembly pipe connection, comprising a valve body, a first rubber ring fixedly connected to the surface of the valve body, a fixed sleeve fixedly connected to the surface of the valve body, a first rigid ring fixedly connected to the inner surface of the fixed sleeve, a second rubber ring fixedly connected to the surface of the first rigid ring, a second rigid ring fixedly connected to the surface of the second rubber ring, a force-applying movable sleeve threadedly connected to the surface of the fixed sleeve, an outer pipe movably connected to the surface of the valve body, a connecting seat provided on the surface of the valve body, a rotating head movably connected to the surface of the connecting seat, a receiving groove opened inside the rotating head, a return spring fixedly connected to the surface of the receiving groove, a connecting plate fixedly connected to the surface of the return spring, a locking block fixedly connected to the side of the connecting plate away from the return spring, and a pull rod fixedly connected to the side of the connecting plate away from the locking block.

[0006] Preferably, the first rubber ring is circular, and the first rubber ring is evenly distributed in six groups on the surface of the valve body.

[0007] Preferably, the fixing sleeves are evenly distributed in three groups on the surface of the valve body, and the first rigid ring is in the shape of a ring.

[0008] Preferably, both the second rubber ring and the second rigid ring are annular, and the side of the second rubber ring and the second rigid ring that contacts the fixing sleeve is not fixed to the fixing sleeve.

[0009] Preferably, the force-applying movable sleeve is movably connected to the fixed sleeve and the outer pipe, and the connecting seat is composed of two cylinders with different radii.

[0010] Preferably, the two ends of the reset spring are fixedly connected to the receiving groove and the connecting plate, respectively. The connecting plate is circular and is slidably connected to the receiving groove via the reset spring.

[0011] Preferably, the locking block is block-shaped, and the locking block is connected to the connecting seat by a reset spring and a connecting plate, and the pull rod and the rotating head are slidably connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through the fixed connection between the valve body and the first rubber ring, the fixed connection between the valve body and the fixed sleeve, the fixed connection between the fixed sleeve and the first rigid ring, the fixed connection between the first rigid ring and the second rubber ring, the fixed connection between the second rubber ring and the second rigid ring, the threaded connection between the fixed sleeve and the force-applying movable sleeve, and the movable connection between the valve body and the outer pipe, after the outer pipe and the valve body are sleeved together, the first rubber ring will contact the inner wall of the outer pipe, and the second rubber ring will contact the outer wall of the outer pipe. Rotating the force-applying movable sleeve will push the second rigid ring to apply pressure to the second rubber ring, causing the second rubber ring to deform under the influence of compression and make close contact with the fixed sleeve and the outer pipe respectively, thereby increasing the friction between the outer pipe and the outer pipe, so that the outer pipe is tightly connected to the valve body, ensuring airtightness.

[0014] 2. The rotating head is connected to the connecting seat and the rotating head. The rotating head has an internal receiving groove. The receiving groove is fixedly connected to the return spring, the return spring is fixedly connected to the connecting plate, the connecting plate is fixedly connected to the locking block, and the connecting plate is fixedly connected to the pull rod. Pulling the pull rod causes the locking block to disengage from the connecting seat, which can remove the rotating head from the connecting seat. This allows the rotating head to be removed without adjusting the valve body, preventing unauthorized personnel from rotating the rotating head and affecting the use of the valve body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] A three-way valve for tire assembly pipe connection includes a valve body 1. A first rubber ring 2 is fixedly connected to the surface of the valve body 1. The first rubber ring 2 is used to increase the friction between the valve body 1 and the inner wall of the outer pipe 8, thereby improving the tightness of the connection of the outer pipe 8. A fixing sleeve 3 is fixedly connected to the surface of the valve body 1. The fixing sleeve 3 allows the second rubber ring 5 to be deformed by a force-applied movable sleeve 7. A first rigid ring 4 is fixedly connected to the inner surface of the fixing sleeve 3. A second rubber ring 5 is fixedly connected to the surface of the first rigid ring 4. The second rubber ring 5 is used to increase the friction between the fixing sleeve 3 and the outer wall of the outer pipe 8, thereby improving the tightness of the connection of the outer pipe 8. A second rigid ring 6 is connected. The first rigid ring 4 and the second rigid ring 6 are used to compress the second rubber ring 5, causing the second rubber ring 5 to deform under compression and make close contact with the fixed sleeve 3 and the outer pipe 8 respectively. This increases the friction between the second rubber ring 5 and the outer pipe 8, ensuring that the outer pipe 8 is tightly connected to the valve body 1 and guaranteeing airtightness. A force-applying movable sleeve 7 is threadedly connected to the surface of the fixed sleeve 3. The force-applying movable sleeve 7 is used to apply force to the second rubber ring 5, causing the second rubber ring 5 to deform under compression and make close contact with the fixed sleeve 3 and the outer pipe 8 respectively. This increases the friction between the second rubber ring 5 and the outer pipe 8, ensuring that the outer pipe 8 is tightly connected to the valve body 1 and guaranteeing airtightness. The surface of the valve body 1 is movably connected... An external connecting pipe 8 is provided. A connecting seat 9 is provided on the surface of the valve body 1. The connecting seat 9 is used to connect to the control valve inside the valve body 1. A rotating head 10 is movably connected to the surface of the connecting seat 9. The rotating head 10 is used to facilitate the operator to rotate the control valve inside the valve body 1. A receiving groove 11 is opened inside the rotating head 10. The receiving groove 11 is used to receive a return spring 12, a connecting plate 13, and a locking block 14. The return spring 12 is fixedly connected to the surface of the receiving groove 11. The return spring 12 is used to push the connecting plate 13 and the locking block 14 back to their original positions, so that the locking block 14 is inserted into the connecting seat 9, thereby installing the rotating head 10 on the connecting seat 9. The connecting plate 14 is fixedly connected to the surface of the return spring 12. 3. The connecting plate 13 is used to connect the return spring 12, the locking block 14 and the pull rod 15. It is also used to squeeze the return spring 12, causing the return spring 12 to deform. The locking block 14 is fixedly connected to the side of the connecting plate 13 away from the return spring 12. The locking block 14 is used to insert into the connecting seat 9, thereby installing the rotating head 10 on the connecting seat 9. The pull rod 15 is fixedly connected to the side of the connecting plate 13 away from the locking block 14. The pull rod 15 is used to pull the locking block 14 away from the connecting seat 9, thereby removing the rotating head 10 from the connecting seat 9. This allows the rotating head 10 to be removed without adjusting the valve body 1, preventing non-operators from rotating the rotating head 10 and affecting the use of the valve body 1.

[0025] Furthermore, the first rubber ring 2 is circular in shape, and six groups of the first rubber ring 2 are evenly distributed on the surface of the valve body 1. The first rubber ring 2 is used to increase the friction between the valve body 1 and the inner wall of the outer pipe 8, thereby improving the tightness of the connection of the outer pipe 8.

[0026] Furthermore, the fixing sleeves 3 are evenly distributed in three groups on the surface of the valve body 1. The fixing sleeves 3 allow the second rubber ring 5 to be squeezed and deformed by the force-applied movable sleeve 7. The first rigid ring 4 is in the shape of a ring. The first rigid ring 4 and the second rigid ring 6 are used to squeeze the second rubber ring 5, so that the second rubber ring 5 is deformed by the squeezing and comes into close contact with the fixing sleeve 3 and the outer pipe 8 respectively, thereby increasing the friction between it and the outer pipe 8, so that the outer pipe 8 is tightly connected to the valve body 1, ensuring airtightness.

[0027] Furthermore, both the second rubber ring 5 and the second rigid ring 6 are annular. The side of the second rubber ring 5 and the second rigid ring 6 that contacts the fixed sleeve 3 is not fixed to the fixed sleeve 3. The second rubber ring 5 is used to increase the friction between the fixed sleeve 3 and the outer wall of the outer pipe 8, thereby improving the tightness of the connection of the outer pipe 8.

[0028] Furthermore, the force-applying movable sleeve 7 is movably connected to the fixed sleeve 3 and the outer pipe 8. The force-applying movable sleeve 7 is used to apply force to the second rubber ring 5, so that the second rubber ring 5 is deformed by compression and comes into close contact with the fixed sleeve 3 and the outer pipe 8 respectively, thereby increasing the friction between it and the outer pipe 8, so that the outer pipe 8 is tightly connected to the valve body 1, ensuring airtightness. The connecting seat 9 is composed of two cylinders with different radii. The connecting seat 9 is used to connect the control valve inside the valve body 1.

[0029] Furthermore, the rotating head 10 is used to facilitate the operator to rotate the control valve inside the valve body 1. The receiving groove 11 is used to accommodate the return spring 12, the connecting plate 13, and the locking block 14. The two ends of the return spring 12 are fixedly connected to the receiving groove 11 and the connecting plate 13, respectively. The return spring 12 is used to push the connecting plate 13 and the locking block 14 back to their original positions, so that the locking block 14 is inserted into the connecting seat 9, thereby installing the rotating head 10 on the connecting seat 9. The connecting plate 13 is in the shape of a circular plate. The connecting plate 13 is slidably connected to the receiving groove 11 through the return spring 12. The connecting plate 13 is used to connect the return spring 12, the locking block 14, and the pull rod 15, and at the same time, it is used to squeeze the return spring 12, causing the return spring 12 to deform.

[0030] Furthermore, the locking block 14 is block-shaped and is connected to the connecting seat 9 by a return spring 12 and a connecting plate 13. The locking block 14 is used to insert into the connecting seat 9, thereby mounting the rotating head 10 on the connecting seat 9. The pull rod 15 is slidably connected to the rotating head 10. The pull rod 15 is used to pull the locking block 14 away from the connecting seat 9, thereby removing the rotating head 10 from the connecting seat 9. This allows the rotating head 10 to be removed without adjusting the valve body 1, preventing non-operators from rotating the rotating head 10 and affecting the use of the valve body 1.

[0031] Working principle: After the outer pipe 8 and the valve body 1 are connected together, the first rubber ring 2 will contact the inner wall of the outer pipe 8, and the second rubber ring 5 will contact the outer wall of the outer pipe 8. Rotating the force-applying movable sleeve 7 will push the second rigid ring 6 to apply pressure to the second rubber ring 5, causing the second rubber ring 5 to deform under the pressure and make close contact with the fixed sleeve 3 and the outer pipe 8 respectively, thereby increasing the friction between the outer pipe 8 and the valve body 1, ensuring that the outer pipe 8 is tightly connected to the valve body 1 and ensuring airtightness.

[0032] Pulling the lever 15 causes the locking block 14 to disengage from the connecting seat 9, allowing the rotating head 10 to be removed from the connecting seat 9. This allows the rotating head 10 to be removed without adjusting the valve body 1, preventing unauthorized personnel from rotating the rotating head 10 and affecting the use of the valve body 1.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
