Description

Technical Field

[0001] This utility model relates to the field of anti-leakage structure technology, specifically an anti-leakage structure for an engine sealing device. Background Technology

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc.

[0003] Currently, when connecting the engine to the oil and water lines, clamps are usually used to lock and fix them, which is relatively troublesome to install. Moreover, the clamps can easily scratch the rubber pipes and affect their service life. Therefore, we propose an engine sealing device leak-proof structure. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof structure for an engine sealing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof structure for an engine sealing device, including a connector, the top of which is connected to and fixed with a pipe connector, and the top of the connector is provided with a pipe fixing structure;

[0006] The pipeline fixing structure includes:

[0007] Threaded rings are used to secure rubber pipes by engaging with contact blocks.

[0008] Threaded support, used to connect with a threaded ring and self-locking via threads;

[0009] The compression ring is used to compress the contact block, causing it to bend.

[0010] Preferably, the threaded support is fixed to the top of the connector, the threaded ring is threadedly connected to the threaded support, a compression ring is fixed to the inner side of the threaded ring, and an abutment block is fixed to the top of the threaded ring. The abutment block is made of plastic and has a certain degree of elasticity. After the rubber pipe is inserted into the pipe connector for connection, tightening the threaded ring causes the threaded ring to move downwards with the compression ring, compressing the abutment block and causing it to bend. The abutment block, in conjunction with the outer wall of the pipe connector, compresses the rubber pipe to achieve fixation. When disassembly is required, simply loosen the threaded ring so that the compression ring no longer compresses the abutment block, and the rubber pipe can be removed. The overall disassembly and assembly efficiency is high, and damage to the rubber pipe can be effectively avoided, making it convenient to use.

[0011] Preferably, the threaded support is annular, and the pipe connector is located at the center of the threaded support. After the pipe connector is inserted into the rubber pipe for connection, the external threaded support can provide a certain degree of protection.

[0012] Preferably, the outer wall of the pipe connector is provided with an annular protrusion. After the pipe connector is inserted into the rubber pipe, the annular protrusion can support the rubber pipe, further improving the stability of the installation.

[0013] Preferably, the inner side of the connector is provided with a groove and a thread, and a rubber gasket is placed in the groove. The rubber gasket can ensure the sealing of the connector when it is connected to the engine.

[0014] Compared with the prior art, this utility model provides a leak-proof structure for an engine sealing device, which has the following beneficial effects:

[0015] 1. The engine sealing device's leak-proof structure, through the installation of a connector, pipe fitting, and pipe fixing structure, allows the rubber hose to be inserted into the pipe fitting for connection. By tightening the threaded ring, the threaded ring moves downwards along with the compression ring, squeezing the contact block and causing it to bend. The contact block, in conjunction with the outer wall of the pipe fitting, squeezes the rubber hose, thus securing it. When disassembly is required, simply loosen the threaded ring to stop the compression ring from squeezing the contact block, allowing the rubber hose to be removed. The overall disassembly and assembly efficiency is high, and it effectively avoids damage to the rubber hose, making it convenient to use.

[0016] 2. The engine sealing device has a leak-proof structure. By setting an annular protrusion, the pipe connector can support the rubber pipe after being inserted into the rubber pipe, which further improves the stability of the installation. The inner side of the connector has a groove and a thread. A rubber gasket is placed in the groove. The rubber gasket can ensure the sealing of the connector when it is connected to the engine.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: an engine sealing device anti-leakage structure, including a connector 1, a pipe connector 2 connected and fixed to the top of the connector 1, and a pipe fixing structure 4 provided on the top of the connector 1, the pipe fixing structure 4 including: a threaded ring 41, a contact block 42, a threaded support 43, and a compression ring 44.

[0023] The threaded support 43 is fixed to the top of the connector 1. The threaded ring 41 is threadedly connected to the threaded support 43. A compression ring 44 is fixed to the inner side of the threaded ring 41, and an abutment block 42 is fixed to the top of the threaded ring 41. The abutment block 42 is made of plastic and has a certain degree of elasticity. After the rubber pipe is inserted into the pipe connector 2 for connection, by tightening the threaded ring 41, the threaded ring 41 moves downward with the compression ring 44 to compress the abutment block 42, causing the abutment block 42 to bend. The abutment block 42 cooperates with the outer wall of the pipe connector 2 to compress the rubber pipe and achieve fixation. When disassembly is required, simply loosen the threaded ring 41 so that the compression ring 44 no longer compresses the abutment block 42, and the rubber pipe can be removed. The overall disassembly and assembly efficiency is high, and damage to the rubber pipe can be effectively avoided. It is convenient to use.

[0024] The threaded support 43 is annular, and the pipe connector 2 is located at the center of the threaded support 43. After the pipe connector 2 is inserted into the rubber pipe for connection, the external threaded support 43 can play a certain protective role. The outer wall of the pipe connector 2 is provided with annular protrusions. Through the annular protrusions, after the pipe connector 2 is inserted into the rubber pipe, the annular protrusions can support the rubber pipe, further improving the stability of the installation. The inner side of the connector 1 is provided with a groove and threads. A rubber gasket 3 is placed in the groove. The rubber gasket 3 can ensure the sealing when the connector 1 is connected to the engine.

[0025] In this invention, during use, the connector 1 is first threadedly connected to the engine, and the entire device is installed on the engine. The rubber hose is then inserted into the pipe connector 2, and the threaded ring 41 is tightened. The threaded ring 41, along with the compression ring 44, moves downwards to compress the contact block 42, causing the contact block 42 to bend. The contact block 42, in conjunction with the outer wall of the pipe connector 2, compresses the rubber hose to achieve fixation. When disassembly is required, simply loosen the threaded ring 41 so that the compression ring 44 no longer compresses the contact block 42, and the rubber hose can be removed. The overall disassembly and assembly efficiency is high, and damage to the rubber hose can be effectively avoided, making it convenient to use.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
