Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a flexible hose for automobiles. Background Technology

[0002] Early automotive hoses were mainly made of natural rubber and used for simple cooling and lubrication systems. As automotive technology continued to develop, the performance requirements for hoses became increasingly stringent, and materials such as synthetic rubber were gradually widely used. At the same time, manufacturing processes evolved from simple manual production to automated production, greatly improving the quality and production efficiency of hoses. According to the usage environment and medium, fuel hoses are used to connect the engine and fuel tank, hydraulic hoses are used in the automotive hydraulic system, air conditioning hoses are used to connect various components of the automotive air conditioning system, water hoses are used to connect components of the automotive cooling system, and air hoses are used to connect components of the automotive intake system.

[0003] During vehicle operation, hoses may rub against surrounding components, such as the vehicle frame or engine parts, or rub against each other due to vehicle vibration. Long-term friction can damage the protective layer on the surface of the hose, thereby weakening the structural strength of the hose and increasing the risk of leakage. Utility Model Content

[0004] The purpose of this invention is to provide a flexible hose for automobiles to solve the problem of wear caused by friction between the hose and surrounding components, as mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flexible hose for automobiles, comprising a hose body, and further comprising a first telescopic tube and a second telescopic tube that can cover the hose body;

[0006] The front end of the hose body is equipped with a first connecting end, and the rear end of the first connecting end is equipped with a first telescopic tube. The rear end of the first telescopic tube is equipped with a fixed connecting ring. The front end of the hose body is equipped with a second connecting end, and the rear end of the second connecting end is equipped with a second telescopic tube. The rear end of the second telescopic tube is equipped with an I-shaped ring, and the outer wall of the I-shaped ring is fitted with a movable connecting ring.

[0007] Preferably, the first telescopic tube is sleeved on the outer wall of the hose body, and the fixed connecting ring can slide on the outer wall of the hose body.

[0008] Preferably, the second telescopic tube is sleeved on the outer wall of the hose body, and the I-shaped ring can slide on the outer wall of the hose body.

[0009] Preferably, the outer wall of the fixed connecting ring is provided with external threads, and the inner wall of the movable connecting ring is provided with internal threads.

[0010] Preferably, the fixed connecting ring can be inserted into the interior of the movable connecting ring, and the movable connecting ring and the fixed connecting ring can be connected to each other by threads.

[0011] Preferably, the inner diameter of the movable connecting ring is larger than the outer diameter of the I-shaped ring, and the movable connecting ring can rotate on the outer wall of the I-shaped ring.

[0012] Preferably, the inner diameters of the first telescopic tube and the second telescopic tube are both greater than the outer diameter of the hose body, and the length of the first telescopic tube and the second telescopic tube after being connected and unfolded is greater than the length of the hose body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the fixed connecting ring is inserted into the interior of the movable connecting ring. During the rotation of the movable connecting ring, the fixed connecting ring can gradually penetrate into the interior of the movable connecting ring. The first telescopic tube and the second telescopic tube can be fixed by the movable connecting ring and the fixed connecting ring. The first telescopic tube and the second telescopic tube can protect the hose body. Under the action of the first telescopic tube and the second telescopic tube, this structure can isolate the hose body from the surrounding components, effectively preventing the hose body from rubbing against the surrounding components.

[0019] 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.

[0020] Example 1: Please refer to Figure 1-4A flexible hose for automobiles includes a hose body 3, and a first telescopic tube 2 and a second telescopic tube 5 that can cover the hose body 3.

[0021] The front end of the hose body 3 is equipped with a first connecting end 1, and the rear end of the first connecting end 1 is equipped with a first telescopic tube 2. The rear end of the first telescopic tube 2 is equipped with a fixed connecting ring 8. The front end of the hose body 3 is equipped with a second connecting end 6, the rear end of the second connecting end 6 is equipped with a second telescopic tube 5, and the rear end of the second telescopic tube 5 is equipped with an I-shaped ring 4. The outer wall of the I-shaped ring 4 is fitted with a rotating connecting ring 7.

[0022] The first telescopic tube 2 is sleeved on the outer wall of the hose body 3, and the fixed connecting ring 8 can slide on the outer wall of the hose body 3;

[0023] The second telescopic tube 5 is sleeved on the outer wall of the hose body 3, and the I-shaped ring 4 can slide on the outer wall of the hose body 3.

[0024] The outer wall of the fixed connecting ring 8 is provided with external threads, and the inner wall of the rotating connecting ring 7 is provided with internal threads;

[0025] The fixed connecting ring 8 can be inserted into the rotating connecting ring 7, and the rotating connecting ring 7 and the fixed connecting ring 8 can be connected to each other by threads;

[0026] The inner diameter of the rotating connecting ring 7 is larger than the outer diameter of the I-shaped ring 4, and the rotating connecting ring 7 can rotate on the outer wall of the I-shaped ring 4;

[0027] The inner diameters of the first telescopic tube 2 and the second telescopic tube 5 are both greater than the outer diameter of the hose body 3, and the length of the first telescopic tube 2 and the second telescopic tube 5 after being connected and unfolded is greater than the length of the hose body 3.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this mechanism, hold the I-shaped ring 4 and the fixed connecting ring 8 and slide the I-shaped ring 4 and the fixed connecting ring 8 towards each other. The fixed connecting ring 8 drives the first telescopic tube 2 to extend, and the I-shaped ring 4 can drive the second telescopic tube 5 to extend. After the first telescopic tube 2 and the second telescopic tube 5 cover the hose body 3 and the fixed connecting ring 8 is inserted into the inside of the rotating connecting ring 7, the operator can rotate the rotating connecting ring 7.

[0029] Working principle: The operator holds the I-shaped ring 4 and the fixed connecting ring 8 and slides them towards each other. The fixed connecting ring 8 causes the first telescopic tube 2 to extend, and the I-shaped ring 4 causes the second telescopic tube 5 to extend. After the first telescopic tube 2 and the second telescopic tube 5 cover the hose body 3 and the fixed connecting ring 8 is inserted into the rotating connecting ring 7, the operator can rotate the rotating connecting ring 7. Since the rotating connecting ring 7 and the fixed connecting ring 8 can be connected by threads, the fixed connecting ring 8 can gradually penetrate deeper into the rotating connecting ring 7 during the rotation of the rotating connecting ring 7. The first telescopic tube 2 and the second telescopic tube 5 can be fixed by the rotating connecting ring 7 and the fixed connecting ring 8, and the hose body 3 can be protected by the first telescopic tube 2 and the second telescopic tube 5.
