AI Technical Summary
Existing automotive hoses have poor sealing performance during use, which can easily lead to leaks at the joints.
The design incorporates components such as a sealing ring, a sliding rod, and a spring. The spring's elasticity drives the sliding rod to move, allowing the sealing ring to fit against the connector, thus increasing the seal between the connecting tube and the hose. The design also maintains stability through a threaded connection between the limiting sleeve and the connector.
It effectively improves the sealing of the connection, avoids leakage at the hose connection, and ensures the stability of the connection.

Description
Technical Field
[0001] This utility model relates to the field of automotive hose technology, specifically to an automotive hose with stable connection. Background Technology
[0002] Automotive hoses are an indispensable component of automobiles, widely used for the transport and connection of various fluids, such as fuel, engine oil, coolant, brake fluid, and air. A utility model patent (CN217926112U) discloses a stable automotive engine intake hose, comprising an intake pipe body. A retaining ring and a filter screen are respectively fitted around the outer edge of the intake pipe body. A first groove is formed on the right side of the filter screen, and a blind hole is formed on the inner wall of the first groove. A fixing bolt is threaded onto the inner wall of the blind hole. A square groove is formed at the bottom of the retaining ring. However, existing automotive hoses often have poor sealing performance during use, easily leading to leaks at the hose connections. Utility Model Content
[0003] The purpose of this invention is to provide a stable automotive hose that solves the problem of poor sealing performance and leakage at the hose connection point during use.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a stable automotive hose, comprising a connecting tube, a connector slidably connected inside the connecting tube, a hose fixedly connected to the end of the connector away from the connecting tube, a fixing block fixedly connected to the outside of the connecting tube, a limit sleeve rotatably connected to the outside of the fixing block, a fixing plate fixedly connected inside the connecting tube, a sleeve fixedly connected to the side of the fixing plate near the connector, a sliding rod slidably connected inside the sleeve, a spring provided inside the sleeve, and a sealing ring fixedly connected to the end of the sliding rod away from the sleeve.
[0005] Preferably, the limiting sleeve is rotatably connected to the connecting pipe, and the limiting sleeve is threadedly connected to the connecting head. The design of the limiting sleeve can limit the movement of the connecting head.
[0006] Preferably, the limiting sleeve has an annular groove inside, which is slidably connected to the fixing block. Through the design of the annular groove, it can cooperate with the fixing block to limit the limiting sleeve.
[0007] Preferably, a limiting ring is fixedly connected inside the sleeve, and the limiting ring is slidably connected to the slide rod. Through the design of the limiting ring, the slide rod can be limited.
[0008] Preferably, one end of the spring contacts the slide rod, and the other end of the spring contacts the sleeve. Through the design of the spring, the sealing ring can be driven to fit against the connector.
[0009] Preferably, the sealing ring is slidably connected to the connecting pipe and contacts the connector. The design of the sealing ring can increase the sealing performance between the connector and the connecting pipe.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model, by incorporating components such as a sealing ring, a sliding rod, and a spring, allows the sliding rod to move due to the spring's elasticity, thereby causing the sealing ring to fit against the connector. This effectively increases the sealing performance between the connecting tube and the hose, solving the problem of poor sealing performance and leakage at the hose connection point when using automotive hoses.
[0012] 2. This utility model, by providing components such as a connector, a fixing block, and a limiting sleeve, allows the connector to be inserted into the connecting pipe. Then, by rotating the limiting sleeve, the limiting sleeve and the connector undergo threaded movement, thereby keeping the connector stable after being inserted into the connecting pipe and preventing displacement of the connector.

[0018] 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.
[0019] Please see Figure 1-4A stable automotive hose includes a connecting tube 1, a connector 2 slidably connected inside the connecting tube 1, a hose 21 fixedly connected to the end of the connector 2 away from the connecting tube 1, a fixing block 3 fixedly connected to the outside of the connecting tube 1, a limiting sleeve 31 rotatably connected to the outside of the fixing block 3, the limiting sleeve 31 rotatably connected to the connecting tube 1, and the limiting sleeve 31 and the connector 2 are connected by threads. Through the design of the limiting sleeve 31, the connector 2 can be limited.
[0020] Please see Figure 2-4 The limiting sleeve 31 has an annular groove 32 inside, which is slidably connected to the fixing block 3. The design of the annular groove 32 can cooperate with the fixing block 3 to limit the limiting sleeve 31. The connecting pipe 1 is fixedly connected to the inside of the fixing plate 4. The side of the fixing plate 4 near the connecting head 2 is fixedly connected to the sleeve 41. The sleeve 41 is slidably connected to the inside of the sleeve 41. The sleeve 41 is fixedly connected to the inside of the sleeve 41. The limiting ring 43 is slidably connected to the sliding rod 42. The design of the limiting ring 43 can limit the sliding rod 42.
[0021] Please see Figure 2-4 A spring 44 is installed inside the sleeve 41. One end of the spring 44 contacts the slide rod 42, and the other end of the spring 44 contacts the sleeve 41. The design of the spring 44 can drive the sealing ring 45 to fit against the connector 2. The end of the slide rod 42 away from the sleeve 41 is fixedly connected to the sealing ring 45. The sealing ring 45 is slidably connected to the connecting pipe 1 and contacts the connector 2. The design of the sealing ring 45 can increase the sealing between the connector 2 and the connecting pipe 1.
[0022] The specific implementation process of this utility model is as follows: In use, the connector 2 is inserted into the connecting pipe 1, and then the connector 2 is limited by hand. Then the limiting sleeve 31 is rotated so that the limiting sleeve 31 and the connector 2 undergo threaded movement, thereby limiting the connector 2 by the limiting sleeve 31, and keeping the connection between the connector 2 and the connecting pipe 1 stable.
[0023] When connector 2 is inserted into connector 1, connector 2 contacts sealing ring 45, causing connector 2 to slide within connector 2, and sealing ring 45 to slide within sleeve 41. Sliding rod 42 compresses spring 44, and the elastic force of spring 44 causes sliding rod 42 to move, which in turn causes sealing ring 45 to move, making sealing ring 45 fit with connector 2, thereby effectively increasing the sealing between connector 2 and connector 1.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
