[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown:

[0021] This utility model relates to a high-pressure connector with strong bearing capacity for oil extraction, comprising a connector sleeve 1, a male connector 2, and a female connector 3. The male connector 2 is sealed and installed inside the connector sleeve 1. A sealing groove 4 is formed on the top of the male connector 2, and a sealing ring 5 is installed inside the sealing groove 4. A second sealing groove 6 is formed on the top end face of the male connector 2, and a second sealing ring 7 is installed inside the second sealing groove 6. The male connector 2 is sealed and inserted into the female connector 3 through the first sealing ring 5 and the second sealing ring 7. The female connector 3 is threaded onto the connector sleeve 1. A fixed anchor is evenly installed on the outer center of the female connector 3. Positioning plate 11 has polygonal positioning holes 12 on its surface. After the female head 3 and the female sleeve 1 are threadedly installed, a positioning groove 13 is provided on the surface of the female sleeve 1 below the positioning plate 11. An elastic component 14 is provided inside the positioning groove 13. A sliding plate 15 is provided on the top of the elastic component 14. A locking plate 16 is provided on the top of the sliding plate 15. Through the elastic action of the elastic component 14, the sliding plate 15 drives the locking plate 16 to be inserted into the polygonal positioning hole 12 for threaded installation and fixation of the female head 3 and the female sleeve 1.

[0022] To solve the above-mentioned technical problems, this patent adopts the following technical structure: a positioning plate 11 is uniformly fixedly installed on the middle of the outer side of the female head 3. The surface of the positioning plate 11 is provided with polygonal positioning holes 12. Before the female head 3 and the female sleeve 1 are threadedly installed, the positioning plate 11 is limited and installed inside the positioning groove 13. After the female head 3 and the female sleeve 1 are threadedly installed, the sliding plate 15 is lifted by the elastic component 14. The sliding plate 15 is provided with a retaining plate 16. The retaining plate 16 passes through the polygonal positioning holes 12. The retaining plate 16 limits the female head 3 and thus fixes the female head 3 to the threaded installation. This solves the problem of loose threads caused by vibration. The sliding plate 15 is set inside the positioning groove 13. The positioning groove 13 limits the installation of the sliding plate 15. The retaining plate 16 positions the female head and together they reinforce the positioning threaded installation of the female head, preventing the female head from becoming loose.

[0023] To mitigate the impact of fluid impact pressure on the sealing performance of the threaded installation, two sealing rings are installed on the top of the male connector 2, distributed on the top and top end face of the male connector 2. This achieves a sealed installation between the male connector 2 and the female connector 3, reduces vibration of the external threaded installation caused by impact pressure, and solves the technical problem of loose threaded installation.

[0024] In at least one embodiment, to limit the sliding plate 15 inside the positioning groove 13 before the male connector 2 and the female connector 1 are threadedly installed, the structure is as follows: a polygonal hole 17 is opened on one side surface of the positioning groove 13, and a polygonal hole 21 is opened on the surface of the sliding plate 15 in the axial direction of the polygonal hole 17. When the sliding plate 15 is compressed and housed inside the positioning groove 13, the polygonal hole 17 and the polygonal hole 21 are fixed by a shaft pin 22. Initially, the sliding plate 15 is fixed inside the positioning groove 13 by the shaft pin 22. After the female connector 3 and the female connector 1 are threadedly installed, the shaft pin 22 is pulled out. The sliding plate 15, through elastic action, causes the retaining plate 16 to pass through the polygonal positioning hole 12. The retaining plate 16 limits the female connector 3 and then thread-installs and fixes the female connector 3.

[0025] In at least one embodiment, three positioning plates 11 are axially and uniformly fixedly installed on the middle outer side of the mother head 3.

[0026] In at least one embodiment, the elastic component 14 is two springs evenly distributed at the bottom of the positioning groove 13.

[0027] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
