[0002] The reliable circulation of the three major mediums of the engine - oil (fuel and lubricating oil), water, and gas - is a prerequisite for its normal operation. The oil and water pipelines, as well as the intake and exhaust pipes, are important structures to ensure the complete circulation of oil, water, and gas. Errors are inevitable in the production process of the oil pipe. When the specifications of the oil pipe deviate from the docking equipment, docking cannot be carried out, or oil leakage is likely to occur at the docking position. Utility Model Content

A channel connected to the oil pipe is provided inside the interface seat, and the outer wall of the oil pipe is welded and fixed to the inner wall of the channel; and a sealing groove is provided on the end face of the interface seat facing away from the oil pipe, which cooperates with a sealing ring to seal the docking end face.
[0005] Furthermore, at least two reinforcing plates are arranged between the interface seat and the oil pipe, and the two reinforcing plates are arranged opposite to each other.
[0006] Furthermore, the interface seat is a triangular plate, and mounting holes are arranged at three end corners of the triangular plate for docking and fixing with the docking equipment.
[0007] Furthermore, the channel includes a first channel and a second channel, the inner diameter of the first channel is smaller than the inner diameter of the second channel; a step is formed at the connection between the first channel and the second channel, the end of the oil pipe abuts against the step, and the outer wall of the oil pipe is welded and fixed to the inner wall of the second channel; the sealing groove is arranged around the port of the first channel.
[0008] Furthermore, an inner step is provided at one end of the casing connected to the oil pipe, and the oil pipe is fixed to the inner step by welding.
[0009] Furthermore, the feed port at one end of the casing away from the oil pipe is configured as a necking structure.
[0010] Furthermore, the casing includes a first pipe and a second pipe, the inner diameter of the first pipe is smaller than the inner diameter of the second pipe, and the connection between the first pipe and the second pipe is set as a flared structure; the other end of the first pipe is connected to the feed port; the other end of the second pipe is welded to the oil pipe.
[0011] Compared with the prior art, the utility model has the following advantages: for the same processing accuracy requirements, the processing difficulty of the interface seat is lower than that of the pipeline. The present application reduces the processing error by setting the interface seat, and ensures the accuracy of the docking precision between the interface seat and the docking equipment. In addition, the oil pipe is welded and fixed to the interface seat, and a sealing groove is set on the interface seat to cooperate with the installation of a sealing ring, which further ensures the sealed docking between the oil pipe and the docking equipment; a reinforcing plate is set between the oil pipe and the interface seat, which further strengthens the stability of the welding between the oil pipe and the interface seat.

[0018] In order to make the technical solution of the present invention more clearly understood by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.
[0019] like Figure 1-Figure 5 As shown, an oil interface component with a stable sealing structure includes an oil pipe 1, a sleeve 4 is arranged at one end of the oil pipe 1, and an interface seat 2 is arranged at the other end. A channel 21 connected to the oil pipe 1 is arranged in the interface seat 2, and the outer wall of the oil pipe 1 is welded and fixed to the inner wall of the channel 21; and a sealing groove 22 is arranged on the end face of the interface seat 2 facing away from the oil pipe 1, which cooperates with a sealing ring to seal the docking end face, thereby ensuring the sealed docking between the interface seat 2 and the docking equipment.
[0020] It can be understood that for the same processing accuracy requirements, the processing difficulty of the interface seat 2 is lower than that of the oil pipe 1. The present application reduces the processing error by setting the interface seat 2 (compared with the original oil pipe 1 directly docking with the docking device) to ensure the accuracy of the docking precision between the interface seat 2 and the docking device.
[0021] In order to further enhance the stability of welding between the oil pipe 1 and the interface seat 2, at least two reinforcing plates 3 are arranged between the interface seat 2 and the oil pipe 1, and the two reinforcing plates 3 are arranged opposite to each other. If three reinforcing plates 3 are provided, the interval between adjacent reinforcing plates 3 is 120°, that is, the reinforcing plates 3 are evenly arranged around the oil pipe 1 in the circumferential direction.
[0022] In the present application, the interface seat 2 and the oil pipe 1 are both metal parts. The interface seat 2 is a triangular plate, and mounting holes 23 are set at the three end corners of the triangular plate for docking and fixing with the docking equipment. The structure of the interface seat 2 is not limited to a triangular plate, and can also be a square plate or a metal plate of other structures. The triangular plate is used to ensure the stable connection between the interface seat 2 and the docking equipment while reducing the connection fixing parts.
[0023] Continue reading Figure 3 It can be seen that the channel 21 includes a first channel 211 and a second channel 212, and the inner diameter of the first channel 211 is smaller than the inner diameter of the second channel 212; a step is formed at the connection between the first channel 211 and the second channel 212, and the end of the oil pipe 1 abuts against the step, and the outer wall of the oil pipe 1 is welded and fixed to the inner wall of the second channel 212; the sealing groove 22 is arranged around the port of the first channel 211.
[0024] Continue reading Figure 4 and Figure 5 It can be seen that an inner step is provided at one end of the casing 4 connected to the oil pipe 1, and the oil pipe 1 is welded and fixed to the inner step to further ensure the sealing of the weld. The feed port 43 at the end of the casing 4 away from the oil pipe 1 is set as a constricted structure to ensure smooth oil inlet and convenient docking of the feed port 43.
[0025] In order to further ensure smooth oil flow into the casing 4 and avoid excessive pressure at the oil inlet of the casing 4, the casing 4 is designed to be a first pipeline 41 and a second pipeline 42. The inner diameter of the first pipeline 41 is smaller than the inner diameter of the second pipeline 42, and the connection between the first pipeline 41 and the second pipeline 42 is set to a flared structure; the other end of the first pipeline 41 is connected to the feed port 43; the other end of the second pipeline 42 is welded to the oil pipe 1.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
