Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to an anti-leakage oil pump. Background Art

[0002] The role of the oil pump in the lubrication system: The role of the oil pump is to increase the oil to a certain pressure and force it to the moving surfaces of various engine parts. The oil pump structure can be divided into two types: gear type and rotor type. Gear oil pumps are further divided into internal gear type and external gear type, and the latter is generally called gear oil pump.

[0003] At present, during the operation of the oil pump, it is necessary to connect external oil pipes to both the inlet and outlet ends of the oil pump. However, there are certain problems in the connection of the external oil pipes. For example, during the process of pipe connection, in order to maintain the sealing between the pipe and the oil pump, a sealing gasket will be included on the connection port. When connecting in this way, due to the large friction between the two sealing gaskets, it will be more laborious for the staff to install the pipe manually by hand. Therefore, the staff will subconsciously rotate the external oil pipe for the purpose of saving effort. Although this method speeds up the pipe connection, it will cause irreversible damage to the sealing gasket on the inner wall of the port. The sealing gasket will be crushed and damaged, which reduces the service life and sealing effect of the sealing gasket, and oil leakage will occur before the expiration of the service life.

[0004] Therefore, it is necessary to provide a new anti-leakage oil pump to solve the above-mentioned technical problems. Utility Model Content

[0025] The outer wall of the fixing tube 9 is provided with a threaded sleeve with a threaded ring 14. Figure 2 As shown, an external thread is provided on the outer wall of the fixing tube 9, and a threaded ring 14 is sleeved on the external thread. A sliding ring 15 is slidably mounted on the outer wall of the fixing tube 9, and the sliding ring 15 is slidably connected to the outer wall of one side of the threaded ring 14.

[0026] Four bevel grooves 16 are provided on the inner wall of the sliding ring 15, and the four bevel grooves 16 are distributed in a circular array.

[0027] The working principle of the anti-leakage oil pump provided by the utility model is as follows:

[0028] When connecting the external pipeline of the oil pump, the staff can first put the external pipe 10 serving as the external pipe into the fixed tube 9, and then rotate the threaded ring 14. During the process, the threaded ring 14 will gradually move laterally under the effect of the thread. At this time, the sliding ring 15 cannot rotate with the threaded ring 14 due to the limitation of the two cross bars. However, during the lateral movement of the threaded ring 14, the connection between the annular slide rail and the slide groove will cause the threaded ring 14 to pull the sliding ring 15 to move laterally. At this time, the four bevel grooves 16 will gradually contact the four telescopic rods 17, so that the four telescopic rods 17 gradually move into the fixed tube 9, and finally the four clamping blocks 18 complete the clamping and fixing of the external pipe 10, and the four clamping blocks 18 respectively complete the clamping of the external pipe 10 from four directions, so that the external pipe 10 and the internal pipe 2 remain coaxial.

[0029] The staff can then pull out the pull rod 22 upwards, and the pull rod 22 will move upwards due to the external force, which will drive the block 23 to move upwards, and finally move the block 23 out of the corresponding groove 21, thereby contacting the limiting effect on the internal threaded tube 7. The staff can then rotate the internal threaded tube 7. During the rotation of the internal threaded tube 7, the transverse ring 6 cannot rotate due to the limiting effect of the limiting rod 5, and can only slide along the direction of the limiting rod 5 under the side effect of the thread, and finally the external tube 10 enters into the internal tube 2, and the outer sleeve 11 is directly mounted on the outer wall of the internal tube 2.

[0030] Compared with the related art, the anti-leakage oil pump provided by the utility model has the following advantages:

[0031] Beneficial effects:

[0032] The utility model provides a leakage-proof oil pump. During the process of connecting an external pipeline, the device can drive the sliding ring 15 to move horizontally by rotating the threaded ring 14, so as to quickly fix the external pipe 10 by means of four telescopic rods 17, and at the same time drive the lateral movement ring 6 to move horizontally by rotating the internal threaded tube 7. Under the limit of the limit rod 5, the external pipe 10 and the outer sleeve 11 are kept to move horizontally, so that the sealing gasket 1 3 and the sealing gasket 2 12 and the sealing gasket 3 13 are kept in a horizontal insertion mode, avoiding the damage of the sealing gasket caused by rotation during the insertion process, thereby improving the protection effect of the sealing gasket, and at the same time, the force is mainly transmitted through the thread, which reduces the labor intensity of the staff.
