Description

Technical Field

[0001] The utility model relates to the technical field related to pipeline connection, in particular to an oil pump pipeline connection component. Background Art

[0002] High-pressure oil pipes are part of high-pressure oil circuits, which require them to withstand a certain oil pressure and have a certain fatigue strength to ensure the sealing requirements of the pipelines. Automotive high-pressure oil pipes are mainly used in high-pressure injection diesel engines and high-pressure injection direct injection gasoline engines, and can withstand the oil pressure required during engine operation; especially at the connection between the oil pump port and the external pipeline, the oil pressure impact force is relatively large, so a connecting assembly is required to connect the pipelines on both sides, but the structure of existing connecting assemblies is usually relatively simple, and they are prone to cracking under long-term oil pressure impact, resulting in internal oil leakage.

[0003] Therefore, we propose an oil pump pipeline connection assembly to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0022] Reference Figure 1-3 A oil pump pipeline connection component includes a group of pipelines 1, the specifications of the group of pipelines 1 are matched, and sleeves 2 are respectively sleeved on the outside of the group of pipelines 1. The extension length of the sleeve 2 is greater than the outer end of the pipeline 1. When the side walls of the sleeves 2 on both sides are butted, there is still a distance between the pipelines 1 on both sides, thereby reducing the impact of the oil pressure on the pipeline joint. An annular limiting groove 201 is opened on the side wall of the end of the positioning ring 3 close to the sleeve 2, and a limiting rod 202 is connected to the side wall of the sleeve 2 corresponding to the position of the limiting groove 201. The limiting groove 201 and the limiting rod 202 are both L-shaped in design. The limiting rod 202 extends into the limiting groove 201, and the adjacent side wall surfaces of the two are covered with a smooth layer to facilitate the sliding fit of the two.

[0023] A positioning ring 3 is connected to one end of the sleeves 2 on both sides that are away from each other. A brush 301 is connected to the inner wall of the positioning ring 3. The brush 301 is in contact with the side wall of the pipeline 1. The side wall of the pipeline 1 is cleaned before installation by the brush 301 to ensure the cleanliness of the installation position and avoid shaking caused by excessive impurities. At the same time, external impurities are isolated during use to prevent them from entering the positioning ring 3 and the sleeve 2. A group of positioning bolts 4 are arranged on the side wall of the positioning ring 3. A group of threaded holes 401 penetrating on both sides are opened on the side wall of the positioning ring 3. The positioning bolts 4 are screwed in the threaded holes 401, and the inner ends of the positioning bolts 4 are in contact with the side wall of the pipeline 1. The positioning ring 3 is stably fixed to the outside of the pipeline 1 by the group of positioning bolts 4, thereby ensuring the overall stability of the positioning ring 3 and the sleeve 2.

[0024] A connecting pipe 5 is provided at the connection between the sleeves 2 on both sides. The adjacent side wall surfaces of the connecting pipe 5 and the sleeve 2 are both provided with threads. A grip groove 501 is opened on the side wall surface of the connecting pipe 5. The inner wall surface of the grip groove 501 is covered with a friction layer, which is convenient for the user to rotate the connecting pipe 5. The sleeves 2 on both sides can be stably connected by utilizing the cooperation of the threads.

[0025] A group of connecting rods 6 for connecting and fixing the two are arranged between the positioning rings 3 on both sides. The connecting rod 6 is designed in a C shape as a whole. A connecting groove 601 is opened on the side wall of the positioning ring 3. Both ends of the connecting rod 6 extend to the connecting grooves 601 on both sides respectively. A fixing pin 602 for fixing the two is arranged at the connection between the connecting groove 601 and the connecting rod 6. Pin holes are opened on the side walls corresponding to the positions of the connecting groove 601 and the connecting rod 6. The fixing pin 602 is inserted into the pin hole to fix the position of the connecting rod 6, and then the positioning rings on both sides are moved inward by utilizing the action of a group of connecting rods 6, thereby ensuring the stability of the internal sleeve docking.
