Description

Technical Field

[0001] This utility model relates to the technical field of rubber sealing water pipes for automobile engines, and particularly to a rubber sealing water pipe for automobile engines. Background Technology

[0002] Traditional automotive engine rubber-sealed water hoses generally use clamp-type or planar compression-type sealing structures, whose technical defects have seriously restricted the reliability and economy of automotive cooling systems. Planar compression seals rely on the uniform compression deformation of the rubber ring, but due to processing errors or installation deviations, local pressure may be insufficient, leading to minor leaks. After long-term operation, rubber aging exacerbates the risk of leakage, resulting in a high risk of seal failure. Clamp seals require bolt tightening, but bolts are prone to loosening under vibration, causing the sealing surface to separate. Coolant leakage can lead to engine overheating or even spontaneous combustion. In addition, the split structure requires multiple assembly processes (such as welding and bonding), which are time-consuming, complex, and labor-intensive. Furthermore, the sealing surface requires high-precision machining, increasing mold costs and making it prone to seal failure due to accumulated tolerances.

[0003] Therefore, this application provides a rubber-sealed water hose for automotive engines to meet the requirements. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the background art mentioned above, and to propose a rubber sealing water pipe for automobile engines.

[0005] The technical problem to be solved by this utility model is to provide a rubber-sealed water hose for automobile engines to solve the problems of existing rubber-sealed water hoses for automobile engines.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A rubber-sealed water hose for an automobile engine includes a rubber hose, an mounting assembly for mounting the rubber hose, and a tightening assembly for tightening the rubber hose. One end of the rubber hose is tightly fitted to one end of the mounting assembly. The tightening assembly is sleeved and installed at the point where the rubber hose and the mounting assembly are tightly fitted together. The inner surface of the tightening assembly is detachably connected to one end of the rubber hose by an internal thread. One inner surface of the tightening assembly is tightly fitted to the surface of one end of the rubber hose.

[0007] Preferably, the mounting assembly includes a connector and a mounting ring. One end of the connector is tightly fitted to one end of the rubber tube, and the outer surface of the end of the connector that is tightly fitted to the rubber tube is provided with an external thread. The mounting ring is sleeved on the outer surface of the connector, and the mounting ring and the connector are integrally and tightly connected.

[0008] Preferably, the mounting assembly further includes a tight ring, and the connector has an external slot for mounting the tight ring.

[0009] Preferably, the tight fitting component includes a sleeve, which is fitted onto the joint between the connector and the rubber tube, and the sleeve has an internal thread pitch that matches the external surface of the connector.

[0010] Preferably, the tight assembly further includes a compression ring, a tight ring, and a damping ring, and the compression ring, the tight ring, and the damping ring are arranged sequentially from the connector toward the rubber tube, and the outer surface of the damping ring is integrally and fixedly connected to the inner wall of the rubber tube.

[0011] Preferably, one side surface of the extrusion ring is in close contact with one end of the connector adjacent to the rubber tube, the other side surface of the extrusion ring is in close contact with the outer surface of the tight ring, and the extrusion ring is funnel-shaped.

[0012] Preferably, the surface of the mounting ring is annular, and the mounting ring has a connection hole.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, the axial thrust generated by the internal thread of the sleeve and the external thread of the connector is converted into a radial pressure gradient through the wedge structure of the funnel-shaped extrusion ring. This not only quickly fills the sealing surface but also avoids local overpressure fatigue cracking of the rubber tube. Furthermore, the elastic deformation of the tight ring embedded in the connector placement groove can automatically compensate for machining tolerances or installation errors, thus achieving dynamic sealing.

[0014] In the above solution, a triple seal is achieved through the elastic compensation of the tight ring, the plastic deformation of the tight ring, and the vulcanization fixation of the damping ring. With the cooperation of stepped pressure distribution and physical anchoring, the sealing performance can still be maintained even if a single layer fails. Attached Figure Description

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention provides a rubber sealing water hose for an automobile engine, comprising: a rubber hose 1, an mounting assembly 2 for mounting the rubber hose 1, and a tightening assembly 3 for tightening the rubber hose 1. One end of the rubber hose 1 is tightly fitted to one end of the mounting assembly 2. The tightening assembly 3 is sleeved and installed at the tightly fitted area between the rubber hose 1 and the mounting assembly 2. The inner surface of the tightening assembly 3 is detachably connected to one end of the rubber hose 1 by an internal thread. One inner surface of the tightening assembly 3 is tightly fitted to the surface of one end of the rubber hose 1.

[0022] Mounting assembly 2 includes a connector 21 and a mounting ring 22. One end of the connector 21 is tightly fitted to one end of the rubber tube 1, and the outer surface of the end of the connector 21 that is tightly fitted to the rubber tube 1 is provided with an external thread. The mounting ring 22 is sleeved on the outer surface of the connector 21, and the mounting ring 22 and the connector 21 are integrally and tightly connected. It should be noted that the surface of the mounting ring 22 is annular, and the mounting ring 22 is provided with a connection hole 23; In one specific implementation: the mounting ring 22 wraps the connector 21 with an integrated structure, and its equally angled connecting holes 23 not only facilitate subsequent positioning and installation, but also achieve uniform stress distribution, avoiding the early cracking problem caused by local stress concentration in traditional split structures.

[0023] Mounting assembly 2 also includes a tight ring 24. The connector 21 has a placement groove 25 on its outside for mounting the tight ring 24. The tight ring 24 is mounted inside the placement groove 25.

[0024] The tight assembly 3 includes a sleeve 31, which is fitted onto the connector 21 and the rubber tube 1 at the tight fit, and the sleeve 31 has a thread pitch size that matches the outer surface of the connector 21. The tight assembly 3 also includes a compression ring 32, a tight ring 33 and a damping ring 34, and the compression ring 32, the tight ring 33 and the damping ring 34 are arranged sequentially from the connector 21 toward the rubber tube 1, and the outer surface of the damping ring 34 is integrally fixedly connected to the inner wall of the rubber tube 1. It should be noted that one side surface of the compression ring 32 is in close contact with one end of the plug 21 adjacent to the rubber tube 1, and the other side surface of the compression ring 32 is in close contact with the outer surface of the tight ring 33, and the compression ring 32 is arranged in a funnel shape.

[0025] The working principle provided by this utility model is as follows: When installing the rubber sealing water hose of a car engine, firstly, one end of the rubber hose 1 is tightly fitted to the connector 21. The external thread on the outer surface of the connector 21 is precisely matched with the internal thread of the sleeve 31, forming the first detachable connection. At this time, the sleeve 31 is screwed into the thread of the connector 21. The axial thrust is converted into radial pressure through the funnel-shaped compression ring 32. The wedge-shaped design of the compression ring 32 unexpectedly generates a pressure gradient distribution. The pressure is the greatest at the near end (close to the connector 21), which quickly fills the sealing surface. The pressure decreases at the far end, avoiding excessive compression that could cause fatigue cracking of the rubber hose 1. This design is more uniform and efficient than the traditional planar compression seal, significantly extending the seal life. At the same time, the tight ring 24 on the outside of the connector 21 undergoes elastic deformation in the placement groove 25, unexpectedly compensating for the small gap between the rubber hose 1 and the connector 21 caused by machining tolerances or installation errors. Dynamic sealing can be achieved without high-precision machining, reducing production costs.

[0026] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
