[0002] The automotive engine is the device that powers the vehicle, the heart of the car, and determines its performance, economy, stability, and environmental friendliness. Depending on the power source, automotive engines can be categorized as diesel, gasoline, electric motors, and hybrids. The engine piping system is a crucial component of the engine, responsible for transporting various fluids and gases.

[0003] Although current technology has many advantages, its disadvantage is that when traditional engine pipes are docked, especially for various fluid transmissions, there is only a single sealing measure, which cannot better seal the engine pipes, resulting in fluid leakage, reducing the sealing of the automobile engine pipes. In addition, due to the vibration generated by the operation of the automobile engine itself, the screws on its pipes cannot be treated with shock resistance, reducing the practicality of the docking nuts used for automobile engine pipes. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that, when conventional engine pipelines are docked, especially for the transmission of various fluids, there is only a single sealing measure, which cannot provide a better sealing treatment for the engine pipeline, resulting in fluid leakage and reducing the sealing performance of the automobile engine pipeline. In addition, due to the vibration generated by the operation of the automobile engine itself, the screws on the pipeline cannot be treated with anti-vibration treatment, which reduces the practicality of the docking nut for the automobile engine pipeline.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a butt nut for automobile engine pipes, comprising:

[0006] two engine pipe bodies;

[0007] a threaded hollow tube fixedly connected to one end of one of the engine pipe bodies;

[0008] A fixed pipe, fixedly connected to one end of the other engine pipe body, and an annular groove is formed inside the fixed pipe;

[0009] An internal thread is provided in the inner wall of the annular groove;

[0010] The connecting plates are fixedly sleeved on the outer surface of the engine pipe body, and a plurality of circular holes are opened on one side of the outer surface of the connecting plates;

[0011] A plurality of anti-vibration washers are provided on one side of the outer surface of one of the connecting plates, and a nut body is provided on one side of each of the plurality of anti-vibration washers;

[0012] A plurality of bolt bodies are movably embedded in the interior of another connecting plate, and a second anti-vibration gasket is provided on one side of the inner wall of each of the plurality of bolt bodies.

[0013] As a preferred embodiment, a first thread is provided on the outer surface of the bolt body, and sealing gaskets are provided on the inner walls of the two connecting plates.

[0014] The technical effect of adopting the above further solution is: making the connection between the two connecting plates tighter, and providing better sealing of the two engine pipe bodies through the two sealing gaskets, thereby completing the second stage of installation sealing.

[0015] As a preferred embodiment, the outer surfaces of the two connecting plates are both provided with a third thread.

[0016] The technical effect of adopting the above further solution is: moving the sealing block horizontally to the edge of another connecting plate, at which time the third threads on the outer surfaces of the two connecting plates overlap.

[0017] As a preferred embodiment, a second thread is formed on the outer surface of the bolt body.

[0018] The technical effect of adopting the above further solution is: the inner wall of the nut body is fitted into the second thread and continuously tightened. The pitch of the first thread is larger than the pitch of the second thread, so the second thread provides additional tightening force.

[0019] As a preferred embodiment, a sealing block is provided on the outer surface of one of the engine pipe bodies.

[0020] The technical effect of adopting the above further solution is: manually rotating the sealing block causes the internal thread to be gradually tightened along the third thread.

[0021] As a preferred embodiment, the inner wall of the sealing block is provided with a thread.

[0022] The technical effect of adopting the above further solution is that the third stage of sealing installation is easily completed by using the thread line.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are:

[0024] 1. In the present invention, first, hold two engine pipe bodies, insert the threaded hollow tube on one end of one of the engine pipe bodies horizontally into the annular groove, and then manually rotate one of the engine pipe bodies so that the threaded hollow tube is gradually tightened through the built-in thread inside the fixed tube, thereby completing the first stage of installation. After the initial installation is completed, the multiple circular holes of the two connecting plates are overlapped. The staff inserts multiple bolt bodies into the multiple circular holes in turn, and then uses the tool to screw the nut body in turn. When the inner wall of the nut body passes through the first thread, it is necessary to increase the torque to screw the nut body so that the inner wall of the nut body fits the second thread and continues to tighten. The pitch of the first thread is larger than that of the second thread. The pitch of the groove is large, so the second thread will provide additional tightening force, making the connection between the two connecting plates tighter, and providing better sealing of the two engine pipe bodies through two sealing gaskets, thereby completing the second stage of installation and sealing. After the installation is completed, the staff begins to move the sealing block horizontally to the edge of the other connecting plate. At this time, the third threads on the outer surfaces of the two connecting plates overlap, so the staff begins to manually rotate the sealing block so that the internal thread line is gradually tightened along the third thread, thereby completing the third stage of sealing installation, thereby achieving better sealing of the engine pipe, reducing fluid leakage, and improving the sealing of the automobile engine pipe.

[0025] 2. The utility model adopts a second anti-vibration gasket arranged on the outer surface of the bolt body, the interior of which is composed of thermoplastic polyurethane, which has high wear resistance, high elasticity and good oil resistance, and is very suitable for high-strength and high-wear-resistant shock absorption. In addition, multiple anti-vibration gaskets arranged on one side of one of the connecting plates are also made of this material to perform anti-vibration treatment, thereby achieving anti-vibration treatment of the screw, thereby improving the practicality of the butt nut for automobile engine pipelines.
