Description

Technical Field

[0001] The utility model relates to a cooling water rubber hose, belonging to the field of cooling systems. Background Art

[0002] The cooling water rubber hose is an important component in the cooling system, mainly used for conveying coolant and connecting two metal cooling water pipes. When connecting two metal cooling water pipes with the cooling water rubber hose, a sealing ring needs to be installed between the cooling water rubber hose and the metal cooling water pipe. In this case, the sealing ring is in a movable state, and it is easy to displace during the assembly process. On the one hand, it increases the risk of leakage. On the other hand, since the step of assembling the sealing ring is added, the assembly efficiency is reduced. Therefore, it is necessary to design a cooling water rubber hose that can improve the assembly efficiency. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a cooling water rubber hose to solve the problems raised in the above background art. The utility model realizes preventing the displacement of the sealing ring during the assembly process and improving the assembly efficiency.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: A cooling water rubber hose includes a corrugated rubber hose. One end of the corrugated rubber hose is provided with a first pipe joint, and the other end of the corrugated rubber hose away from the first pipe joint is provided with a second pipe joint. The first pipe joint, the second pipe joint and the corrugated rubber hose are of an integrally formed structure. A plurality of first sealing rings are evenly installed on the inner surface of the first pipe joint, and the first sealing rings and the first pipe joint are of an integrally formed structure. A plurality of second sealing rings are evenly installed on the inner surface of the second pipe joint, and the second sealing rings and the second pipe joint are of an integrally formed structure. A volume compression member is installed in the space formed by the corrugated rubber hose, the first pipe joint and the second pipe joint.

[0005] Further, the volume compression member includes a first pressure plate. A first pressure plate is provided on the side of the first pipe joint away from the corrugated rubber hose. A second pressure plate is provided on the side of the second pipe joint away from the corrugated rubber hose. A straight threaded cylinder is installed at the middle position of the side of the second pressure plate facing the first pressure plate. A threaded rod is in threaded connection with the straight threaded cylinder. The straight threaded cylinder and the threaded rod are both arranged in the space formed by the corrugated rubber hose, the first pipe joint and the second pipe joint. A round hole is opened at the middle position of one side of the first pressure plate. The end of the threaded rod outside the straight threaded cylinder penetrates through the round hole. One end of the threaded rod close to the first pressure plate is connected and fixed with a first hexahedron. A limiting ring is provided on the side of the round hole away from the first hexahedron. The limiting ring is sleeved on the threaded rod and is connected and fixed with the threaded rod. The first hexahedron and the limiting ring are both in sliding contact with the first pressure plate. A second hexahedron is installed at the middle position of the side of the second pressure plate away from the first pressure plate.

[0006] Further, a first inner hexagonal groove is formed by recessing one side of the first hexahedron away from the threaded rod, and a second inner hexagonal groove is formed by recessing one side of the second hexahedron away from the second pressure plate.

[0007] Further, a first support ring is installed on the side of the first pressure plate facing the first pipe joint, and the first support ring is inserted into the first pipe joint.

[0008] Further, a second support ring is installed on the side of the second pressure plate facing the second pipe joint, and the second support ring is inserted into the second pipe joint.

[0009] Further, multiple layers of polyester cloth are installed inside the corrugated rubber hose, and the polyester cloth extends into the first pipe joint and the second pipe joint.

[0010] Advantages of the present utility model:

[0011] 1. The first sealing ring is integrally formed inside the first pipe joint, and the second sealing ring is integrally formed inside the second pipe joint. Thus, when the first pipe joint and the second pipe joint are sleeved on the metal cold water pipe, there is no need to add the step of installing the sealing ring, improving the assembly efficiency. At the same time, during the assembly process, the first sealing ring and the second sealing ring will not be displaced, improving the assembly quality.

[0012] 2. Use a wrench to clamp the first hexahedron and the second hexahedron respectively, and then turn the first hexahedron with the wrench. Further, the first hexahedron drives the threaded rod to rotate, increasing the length of the threaded rod inside the straight thread cylinder. At this time, the distance between the first pressure plate and the second pressure plate is shortened, and the first pressure plate and the second pressure plate jointly act to squeeze the corrugated rubber hose, reducing the volume of the structure formed by the corrugated rubber hose, the first pipe joint, and the second pipe joint, which is beneficial to reducing the storage space occupied. After separating the threaded rod and the straight thread cylinder, it is convenient to recycle and reuse components such as the first pressure plate and the second pressure plate.

[0013] 3. Before using the first pressure plate and the second pressure plate to seal the first pipe joint and the second pipe joint, an inert gas is injected into the space formed by the corrugated rubber hose, the first pipe joint, and the second pipe joint, thereby slowing down the oxidation rate of the inner wall of the structure formed by the corrugated rubber hose, the first pipe joint, and the second pipe joint.

Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0024] Please refer to Figure 1 and Figure 2, the utility model provides a technical solution: a cooling water rubber hose, including a corrugated rubber hose 1. One end of the corrugated rubber hose 1 is installed with a first pipe joint 2, and the end of the corrugated rubber hose 1 far from the first pipe joint 2 is installed with a second pipe joint 4. The first pipe joint 2, the second pipe joint 4 and the corrugated rubber hose 1 are of an integrally formed structure. A plurality of layers of polyester cloth are installed inside the corrugated rubber hose 1, and the polyester cloth extends into the first pipe joint 2 and the second pipe joint 4. A plurality of first sealing rings 3 are evenly installed on the inner surface of the first pipe joint 2, and the first sealing rings 3 and the first pipe joint 2 are of an integrally formed structure. A plurality of second sealing rings 5 are evenly installed on the inner surface of the second pipe joint 4, and the second sealing rings 5 and the second pipe joint 4 are of an integrally formed structure. The first sealing rings 3 are integrally formed inside the first pipe joint 2, and the second sealing rings 5 are integrally formed inside the second pipe joint 4. Thus, when the first pipe joint 2 and the second pipe joint 4 are sleeved on the metal cold water pipe, there is no need to add the step of installing the sealing ring, improving the assembly efficiency. At the same time, during the assembly process, the first sealing rings 3 and the second sealing rings 5 will not be displaced, improving the assembly quality.

[0025] Refer to Figures 3 - 7 , on the side of the first pipe joint 2 facing away from the corrugated rubber hose 1, there is a first pressure plate 6. On the side of the second pipe joint 4 facing away from the corrugated rubber hose 1, there is a second pressure plate 9. In the middle position of the side of the second pressure plate 9 facing the first pressure plate 6, a straight thread cylinder 13 is installed. A threaded rod 12 is threadedly connected inside the straight thread cylinder 13. The straight thread cylinder 13 and the threaded rod 12 are both arranged in the space formed by the corrugated rubber hose 1, the first pipe joint 2 and the second pipe joint 4. In the middle position of one side of the first pressure plate 6, a round hole 17 is opened. The end of the threaded rod 12 outside the straight thread cylinder 13 penetrates through the round hole 17. One end of the threaded rod 12 close to the first pressure plate 6 is fixedly connected with a first hexahedron 7. On the side of the round hole 17 facing away from the first hexahedron 7, there is a limit ring 15. The limit ring 15 is sleeved on the threaded rod 12 and fixedly connected with the threaded rod 12. The first hexahedron 7 and the limit ring 15 are both in sliding contact with the first pressure plate 6. The first hexahedron 7 and the limit ring 15 jointly act to realize the limitation of the relative position between the threaded rod 12 and the first pressure plate 6.

[0026] Refer to Figures 3 - 7, on the middle position of the side of the second pressure plate 9 facing away from the first pressure plate 6, a second hexahedron 10 is installed. On the side of the first hexahedron 7 facing away from the threaded rod 12, a first internal hexagonal groove 8 is recessed. On the side of the second hexahedron 10 facing away from the second pressure plate 9, a second internal hexagonal groove 11 is recessed. The designs of the first internal hexagonal groove 8 and the second internal hexagonal groove 11 facilitate restricting the positions of the first hexahedron 7 and the second hexahedron 10 by using an internal hexagonal wrench. Clamp the first hexahedron 7 and the second hexahedron 10 respectively with the wrench, and then turn the first hexahedron 7 with the wrench. Further, the first hexahedron 7 drives the threaded rod 12 to rotate, so that the length of the threaded rod 12 in the straight threaded cylinder 13 increases. At this time, the distance between the first pressure plate 6 and the second pressure plate 9 shortens. The first pressure plate 6 and the second pressure plate 9 jointly play a role in squeezing the corrugated rubber tube 1, so that the volume of the structure formed by the corrugated rubber tube 1, the first pipe joint 2 and the second pipe joint 4 is reduced, which is beneficial to reducing the storage space occupied. Before using the first pressure plate 6 and the second pressure plate 9 to block the first pipe joint 2 and the second pipe joint 4, an inert gas is injected into the space formed by the corrugated rubber tube 1, the first pipe joint 2 and the second pipe joint 4, so as to slow down the oxidation rate of the inner wall of the structure formed by the corrugated rubber tube 1, the first pipe joint 2 and the second pipe joint 4. After separating the threaded rod 12 and the straight threaded cylinder 13, it is convenient to recycle components such as the first pressure plate 6 and the second pressure plate 9.

[0027] Refer to Figure 5 , on the side of the first pressure plate 6 facing the first pipe joint 2, a first support ring 14 is installed. On the side of the second pressure plate 9 facing the second pipe joint 4, a second support ring 16 is installed. The first support ring 14 is inserted into the first pipe joint 2, and the second support ring 16 is inserted into the second pipe joint 4, so as to realize the restriction of the relative position between the first pressure plate 6 and the first pipe joint 2, and the restriction of the relative position between the second pressure plate 9 and the second pipe joint 4.
