Description

Technical Field

[0001] This utility model relates to the field of air intake hose technology, and in particular to an air intake hose that is leak-proof. Background Technology

[0002] In automobiles, industrial machinery and other equipment, the intake hose is an important component that connects various parts of the intake system, and its sealing performance directly affects the operating performance and efficiency of the equipment.

[0003] Existing air intake hoses often suffer from leaks due to inadequate sealing at the joints. For example, traditional air intake hose connections often use simple sleeves or clamps for fixation. After prolonged use, factors such as vibration and temperature changes can easily lead to loosening of the connection and failure of the seal, resulting in gas leakage. Gas leakage not only reduces equipment power and increases energy consumption but may also cause other malfunctions, affecting the normal operation of the equipment. Therefore, there is an urgent need to design a leak-proof air intake hose with a reasonable structure and excellent sealing performance to solve the problems existing in current technology. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a leak-proof air inlet hose. Through a unique structural design, it improves the sealing and reliability of the air inlet hose connection, effectively prevents gas leakage, ensures the normal operation of equipment, and reduces energy consumption and equipment failure risks caused by gas leakage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air-intake hose with leak-proof design includes a fixing plate and a pipe body. The fixing plate is provided with a connector, and a sleeve is rotatably sleeved on the pipe body. The sleeve and the connector are mutually engaged. The sleeve is a hexagonal nut sleeve. The fixing plate has two sliding grooves, each of which is provided with a clamping mechanism for clamping the sleeve. The clamping mechanism includes a clamping plate slidably connected in the sliding groove. One end of each clamping plate has a clamping groove that mates with the sleeve. The clamping groove is V-shaped. A threaded rod is rotatably connected to the inner wall of the sliding groove. The threaded rod passes through the clamping plate and is threadedly connected to it.

[0007] Preferably, the two threaded rods pass through the side wall of the fixed plate and are rotatably connected to it, and a handle is fixedly connected to one end of each threaded rod outside the fixed plate.

[0008] Preferably, the outer wall of the connector is provided with an external thread, and the inner wall of the sleeve is provided with an internal thread that mates with the external thread.

[0009] Preferably, a connecting plate is fixedly connected to the inner wall of the connector, and the connecting plate has an insertion port that matches the tube body.

[0010] Preferably, a sealing ring that matches the insertion port is fixedly sleeved on the tube body.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. This utility model improves the sealing and stability of the air intake hose connection by setting a threaded connection between the sleeve and the connector, and by setting a clamping mechanism on the fixing plate to clamp and fix the sleeve. The double fixing method greatly improves the sealing and stability of the air intake hose connection and effectively prevents gas leakage. The clamping groove of the clamping plate in the clamping mechanism is designed in a "V" shape, which matches the shape of the hexagonal nut sleeve. It can evenly apply clamping force to the sleeve, making the connection more secure and avoiding loosening due to vibration and other factors.

[0013] 2. By setting up a pipe body and a connector, and sealing the pipe body and the connector with a sealing ring, the sealing performance of the connection is further enhanced, ensuring that there is no leakage during gas transmission, guaranteeing the normal operation of the equipment, and reducing energy consumption and failure risk.

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Reference Figures 1-6 A leak-proof air inlet hose includes a fixing plate 1 and a pipe body 5. The fixing plate 1 is provided with a connector 4 for connecting to a pipeline. A sleeve 6 is rotatably sleeved on the pipe body 5. The sleeve 6 cooperates with the connector 4, and the sleeve 6 is a hexagonal nut sleeve, which is convenient for installation and disassembly using tools.

[0023] Specifically, the fixed plate 1 has two sliding grooves 7, each containing a clamping mechanism for holding the socket 6. Each clamping mechanism includes a clamping plate 3 slidably connected within the sliding groove 7. At opposite ends of the two clamping plates 3, there are clamping grooves 10 that mate with the socket 6. The clamping grooves 10 are V-shaped, a design that better matches the shape of the hexagonal nut socket, improving clamping stability. A threaded rod 8 is rotatably connected to the inner wall of the sliding groove 7. The threaded rod 8 passes through and is threadedly connected to the clamping plate 3. Rotating the threaded rod 8 causes the clamping plate 3 to slide within the sliding groove 7, thereby clamping or releasing the socket 6.

[0024] Specifically, the outer wall of the connector 4 is provided with an external thread 12, and the inner wall of the sleeve 6 is provided with an internal thread 11 that mates with the external thread 12. Through the mating of the external thread 12 and the internal thread 11, the sleeve 6 and the connector 4 are connected by threads. This connection method can provide better sealing and connection strength.

[0025] Specifically, a connecting plate 13 is fixedly connected to the inner wall of the connector 4. The connecting plate 13 has an insertion port 9 that mates with the tube body 5. The tube body 5 can be inserted into the insertion port 9 to connect the tube body 5 and the connector 4. At the same time, a sealing ring that mates with the insertion port 9 is fixedly fitted onto the tube body 5. The sealing ring further enhances the sealing between the tube body 5 and the connector 4, preventing gas leakage from the connection point.

[0026] When using this utility model, during installation, first insert the tube body 5 into the insertion port 9 of the connecting plate 13 on the inner wall of the connector 4. Since the tube body 5 is fixedly fitted with a sealing ring that matches the insertion port 9, the sealing connection between the tube body 5 and the connector 4 is ensured. Then, rotate the sleeve 6 onto the tube body 5 and align the internal thread 11 of the sleeve 6 with the external thread 12 of the connector 4. By rotating the sleeve 6, the sleeve 6 and the connector 4 are threadedly connected, and the connection between the two is initially fixed. Next, rotate the handle 2, which drives the threaded rod 8 to rotate. Since the threaded rod 8 is threadedly connected to the clamping plate 3, the rotation of the threaded rod 8 causes the clamping plate 3 to slide in the sliding groove 7, so that the two clamping plates 3 move relative to each other, and the clamping groove 10 on the clamping plate 3 gradually approaches the sleeve 6. After the clamping groove 10 contacts the hexagonal surface of the sleeve 6, continue to rotate the handle 2 so that the clamping plate 3 applies clamping force to the sleeve 6. The sleeve 6 is firmly clamped by the "V" shaped clamping groove 10, which further fixes the connection between the sleeve 6 and the connector 4, prevents the sleeve 6 from loosening, and thus improves the sealing and stability of the entire connection.

[0027] During use, the clamping mechanism's clamping and fixing of the sleeve 6, along with the sealing effect of the threaded connection and the sealing ring, effectively prevents gas leakage from the connection point, ensuring the normal operation of the air intake hose. When disassembly is required, rotate the handle 2 in the opposite direction to loosen the clamping plate 3 from the sleeve 6, then rotate the sleeve 6 to remove it from the connector 4, and then pull the tube body 5 out of the insertion port 9.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
