Description

Technical Field

[0001] The present application relates to the technical field of silicone tubes for automobiles, and in particular to a silicone tube for automobile pipelines. Background Art

[0002] Silicone tubing is made by adding raw silicone rubber to a two-roll mill or closed kneader, gradually adding white carbon black and other additives, and repeatedly refining until uniform. Silicone tubing is widely used in automotive piping because it is cold-resistant and heat-resistant, non-toxic, and odorless.

[0003] Nowadays, silicone tubes for automobile pipelines are common on the market. When using silicone tubes to connect automobile pipes, first put the cut silicone tubes on the pipe openings, and then use special tools to lock the special clamps on the silicone tubes to fix them. It is difficult to install or remove the silicone tubes without special tools. Utility Model Content

[0004] The embodiment of the present application provides a silicone tube for automobile pipelines, which can improve the technical problem of silicone tubes being difficult to install and disassemble in the related art.

[0005] An embodiment of the present application provides a silicone tube for automobile pipelines, including: a silicone tube, a connecting tube and a convergence mechanism, one end of the silicone tube is sleeved on the connecting tube, the convergence mechanism includes a mounting ring, a convergence tube and a locking ring, a plurality of convergence grooves are provided on the convergence tube, one end of the convergence tube is fixedly connected to the mounting ring, the inner diameter of the locking ring gradually decreases in the direction away from the mounting ring, the inner surface of the locking ring and the outer surface of the convergence tube are both provided with threads, and the mounting ring, the convergence tube and the locking ring are all sleeved on the silicone tube.

The tightening groove allows one end of the tightening tube to be tightened. As the locking ring continues to approach the mounting ring, the tightening tube continues to increase the pressure on the silicone tube until the silicone tube and the connecting tube are firmly connected, and then stop twisting the locking ring; when the silicone tube needs to be removed, twist the locking ring in the opposite direction to make the tightening tube rebound and relax the pressure on the silicone tube, and then remove the silicone tube from the connecting tube. Therefore, the silicone tube can be installed and removed by only using common tools to twist the locking ring.

[0023] Based on this, in order to improve the problem of difficult installation and disassembly of silicone tubes in the related art, the embodiments of the present application provide the following solution.

[0024] The following combination Figures 1 to 6 The utility model is described in further detail.

[0025] The present embodiment discloses a silicone tube for automobile pipelines: a silicone tube for automobile pipelines includes a silicone tube 1, a connecting tube 2, and a constricting mechanism. One end of the silicone tube 1 is sleeved on the connecting tube 2. The constricting mechanism includes a mounting ring 31, a constricting tube 32, and a locking ring 33. The constricting tube 32 is provided with multiple constricting grooves 321. One end of the constricting tube 32 is fixedly connected to the mounting ring 31. The inner diameter of the locking ring 33 gradually decreases in a direction away from the mounting ring 31. The inner surface of the locking ring 33 and the outer surface of the constricting tube 32 are both provided with threads. The mounting ring 31, the constricting tube 32, and the locking ring 33 are all sleeved on the silicone tube 1. The outer surfaces of the mounting ring 31 and the locking ring 33 are processed into hexagons. The inner diameter of the constricting tube 32 gradually increases in a direction away from the mounting ring 31.

[0026] A plurality of fixing protrusions 322 are provided on the inner surface of the converging tube 32 , and the fixing protrusions 322 are integrally formed with the converging tube 32 ;

[0027] A rib 21 is fixedly provided on the outer surface of the connecting pipe 2 at one end close to the locking ring 33 .

[0028] From the above, it can be seen that the embodiment of the present application provides a silicone tube for automobile pipelines, and the minimum inner diameters of the mounting ring 31, the constricting tube 32 and the locking ring 33 are all larger than the radius of the rib 21, so that they can pass through the rib 21 and be connected to the connecting tube 2; when installing the silicone tube 1, first put the mounting ring 31, the constricting tube 32 and the locking ring 33 on the silicone tube 1 and make the side of the mounting ring 31 not connected to the constricting tube 32 face the opening of the silicone tube 1, and make the end with the larger inner diameter of the locking ring 33 face the constricting tube 32, then put one end of the silicone tube 1 on the connecting tube 2, and then dock the pipe mouth of the constricting tube 32 with the locking ring 33, and then use a wrench to tighten the mounting ring 31. After the locking ring 33 is fixed and turned with a wrench, the threads on the inner surface of the locking ring 33 are connected to the threads on the outer surface of the converging tube 32. Then the locking ring 33 is continued to be turned. The locking ring 33 gradually approaches the mounting ring 31 under the action of the threads. Since the inner diameter of the locking ring 33 gradually decreases in the direction away from the mounting ring 31, the part of the converging tube 32 away from the mounting ring 31 begins to gradually converge inward under the action of the locking ring 33 and presses the silicone tube 1 onto the connecting tube 2. The converging groove 321 allows one end of the converging tube 32 to converge. As the locking ring 33 continues to approach the mounting ring 31, the converging tube 32 continuously increases the pressure on the silicone tube 1 until the silicone tube 1 and the connecting tube are 2, and then stop twisting the locking ring 33; since the inner diameter of the converging tube 32 gradually increases in the direction away from the mounting ring 31, the converging tube 32 can play different compensatory roles in the pressure exerted on the silicone tube 1 at positions of different lengths from the mounting ring 31 during the converging process, so that the pressure exerted on the silicone tube 1 by the contact portion of the converging tube 32 and the silicone tube 1 is more balanced, thereby improving the fixing effect of the converging tube 32 on the silicone tube 1; the fixing protrusion 322 can increase the friction between the converging tube 32 and the silicone tube 1 when the converging tube 32 presses the silicone tube 1, thereby making the connection between the converging tube 32 and the silicone tube 1 more stable and preventing the silicone tube 1 from being subjected to long-term vibration The movement causes it to be disconnected from the binding tube 32; when the binding tube 32 presses the silicone tube 1, the part of the silicone tube 1 that is sleeved on the connecting tube 2 begins to shrink, so that the part of the silicone tube 1 that contacts the rib 21 is pressed against the rib 21, which can improve the sealing of the connection between the connecting tube 2 and the silicone tube 1 and reduce the probability of leakage of the internal fluid of the silicone tube 1; when the silicone tube 1 needs to be removed, the locking ring 33 is twisted in the opposite direction to make the binding tube 32 rebound and release the pressure on the silicone tube 1, and then the silicone tube 1 can be removed from the connecting tube 2, so that the silicone tube 1 can be installed and removed by only using common tools such as a wrench to twist the locking ring 33, which is convenient for users to use the silicone tube 1.

[0029] In some embodiments, see Figure 1 A buffer pad 4 is sleeved on the convergence tube 32 , and one side of the buffer pad 4 abuts against the mounting ring 31 .

[0030] With such arrangement, when the locking ring 33 is twisted to make the locking ring 33 approach the mounting ring 31, the locking ring 33 will contact and compress the buffer pad 4. The buffer pad 4 can damp the locking ring 33, thereby reminding the user after the locking ring 33 locks the silicone tube 1 on the connecting tube 2, avoiding the user from over-tightening the locking ring 33, which may cause the locking ring 33 and the threads on the constricting tube 32 to be stuck or the constricting tube 32 to be damaged due to excessive constriction.

[0031] Optionally, see Figures 1 to 5 The converging tube 32 is also provided with a locking assembly, which includes an upper fixing ring 51, a lower fixing ring 52 and two bolts 53. Threaded holes are provided at both ends of the lower fixing ring 52. One end of the bolt 53 passes through the upper fixing ring 51 and is threadedly connected to the lower fixing ring 52 through the threaded hole.

[0032] A clamping groove 511 is formed on the inner circumference of the upper fixing ring 51 and the inner circumference of the lower fixing ring 52 . A rubber pad 6 is clamped inside the clamping groove 511 .

[0033] When the locking ring 33 is tightened, the upper and lower fixing rings 51 and 52 are tightened, and the locking ring 33 is tightened.

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
