Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a high-sealing sealing structure of a pin-socket fitting, comprising: a sealing mechanism 1, an auxiliary mechanism 2 is provided on the inner wall of the sealing mechanism 1, the sealing mechanism 1 comprises a sleeve 11, a sealing ring 12 is provided on the inner wall of the sleeve 11, the inner wall of the sleeve 11 is fixedly connected to one side of the sealing ring 12, a semicircular ring 13 is provided on the inner wall of the sealing ring 12, the inner wall of the sealing ring 12 is fitted and connected with the inner side of the semicircular ring 13, a connecting plate 14 is provided on the outer side of the semicircular ring 13, the outer side of the semicircular ring 13 is fixedly connected to one end of the connecting plate 14, an extrusion block 16 is provided on the other end of the connecting plate 14, the other end of the connecting plate 14 is in sliding contact with one side of the extrusion block 16, an outer ring 15 is provided on one end of the extrusion block 16, one end of the extrusion block 16 is fixedly connected to the inner side of the outer ring 15, the bottom side of the outer ring 15 is fixedly connected to one end of the folding rod 111, One end of the rod 111 is provided with a convex disc 110, one end of the folding rod 111 is fixedly connected to the bottom end of the convex disc 110, and the bottom end of the convex disc 110 is provided with an empty tube 112. The bottom end of the convex disc 110 is movably connected to the inner wall of the empty tube 112, and a grab plate 19 is provided on the side of the inner wall of the empty tube 112. The side end of the inner wall of the empty tube 112 is movably connected to the middle end of the grab plate 19, and the bottom end of the grab plate 19 is movably connected to the inner wall of the convex disc 110. The outer side is in movable contact, and a needle body 18 is provided on one side of the grab plate 19. One side of the grab plate 19 is in contact with the outer side of the bottom end of the needle body 18, and the outer side of the needle body 18 is in contact with the inner side of the sealing ring 12. The port of the convex disc 110 is fixedly connected with the bottom end of the sleeve 11. A limiting rod 17 is provided on the inner wall of the connecting plate 14. The inner wall of the connecting plate 14 is in sliding contact with one side of the limiting rod 17, and one end of the limiting rod 17 is fixedly connected to one side of the sleeve 11.

[0026] In this embodiment, when the high-seal sealing structure of this type of pin-sleeve fitting is used, first, a sealing ring 12 is designed on the inner side of the sleeve body 11, the needle body 18 is located in the sleeve body 11 and the position required for sealing passes through the sealing ring 12. In order to increase the sealing effect, the outer ring 15 is rotated. However, during the rotation, the inner extrusion block 16 will exert an external force on the connecting plate 14, forcing it to move in its original position, and then the semi-circular ring 13 will enter the inner wall of the sealing ring 12. This method can effectively compress the sealing ring 12 and eliminate the gap between the needle body 18 and the sealing ring 12. Secondly, in order to prevent the needle body 18 from easily falling off inside the sleeve body 11, a hollow tube 112 is provided at the bottom end of the sleeve body 11. When the outer ring 15 rotates, the convex disc 110 in the hollow tube 112 will rotate. Since the grab plate 19 is affected by the rotation of the convex disc 110, the angle of the grab plate 19 will change, so that the top end of the grab plate 19 will be in close contact with the needle body 18, and the needle body 18 will be fixed in the sleeve body 11 in a clamping manner, thereby preventing it from easily falling off inside the sleeve body 11. This clamping mechanism increases the stability of the needle body 18 and ensures that it will not fall off due to external force or vibration during use.

[0028] like Figure 1-Figure 4 As shown, the auxiliary mechanism 2 includes an insert rod 21, one end of which is provided with a fixed block 22, one end of which is clamped with the inner wall of the fixed block 22, one end of which is fixedly connected to one side of the sleeve 11, and one end of the insert rod 21 is provided with a folding rod 111 on the outer side, and one end of the insert rod 21 is connected through the inner wall of the folding rod 111.

[0029] In this embodiment, after the outer ring 15 rotates to the designed position, the insertion rod 21 in the folding rod 111 can be pushed to enter the fixed block 22. Once it enters, the position of the outer ring 15 can be limited, so that it can remain in the position after rotation, which can prevent accidental unlocking during use, enhance operational safety, reduce potential safety hazards, and only need to push the insertion rod 21 to complete the locking, avoiding the complicated manual adjustment process and improving work efficiency.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
