However, this approach still presents challenges for maintenance personnel, making disassembly and repair inconvenient and reducing maintenance efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure oil pipe connector to solve the problems mentioned in the background art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A high-pressure oil pipe connector includes a disconnection mechanism, a bending mechanism at the top of the disconnection mechanism, and a connection mechanism at the top of the bending mechanism.

[0008] The disconnection mechanism includes a first connecting pipe, the inner wall of which is provided with a threaded groove, and a threaded pipe is threadedly connected to the inner wall of the threaded groove. A sealing ring is fixedly connected to the top of the threaded pipe, and a second connecting pipe is fixedly connected to the bottom of the threaded pipe.

[0009] A further improvement of the present invention is that: a locking block is fixedly connected to the bottom of the connecting pipe, a locking hole is opened on the outer wall of the locking block, and a pressing member is slidably connected to the outer wall of the locking block.

[0010] A further improvement of the present invention is that: a shrink-fitting member is fixedly connected to the outer wall of the second connecting pipe, a locking pin is slidably connected to the inner wall of the shrink-fitting member, a return spring is fixedly connected to the bottom of the locking pin, and one end of the return spring is fixedly connected to the shrink-fitting member.

[0011] A further improvement of the present invention is that a flange is fixedly connected to the top of the connecting pipe.

[0012] A further improvement of the present invention is that the bending mechanism includes a second flange, the bottom of the second flange is fixedly connected to a first flange, a flexible hose is fixedly connected to the top of the second flange, a metal stretching tube is sleeved on the outer wall of the flexible hose, and the bottom of the metal stretching tube is fixedly connected to the second flange.

[0013] A further improvement of the present invention is that the connecting mechanism includes a wire-drawing interface, the bottom of which is fixedly connected to a flexible tube, and an annular locking block is sleeved on the outer wall of the wire-drawing interface. One end of the annular locking block is rotatably connected to a rotating shaft, and the other end of the annular locking block is fixedly connected to a connector.

[0014] A further improvement of the present invention is that: the outer wall of the rotating shaft is rotatably connected to an annular locking block two, and one end of the annular locking block two is fixedly connected to a connecting piece two.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a high-pressure oil pipe connector. It comprises a connecting pipe (first type), a threaded groove, a locking hole, a locking block, a pressing component, a sealing ring, a threaded pipe, a connecting pipe (second type), a shrinking component, a return spring, and a locking pin. When the oil pipe connector needs maintenance or inspection, the pressing component slides along the outer wall of the locking block, squeezing the locking pin into the shrinking component. The return spring retracts, leaving only the round head of the locking pin in the locking hole, reducing resistance. Connecting pipe (first type) and connecting pipe (second type) can then be gripped and rotated to separate. The threaded pipe and threaded groove perform threaded movement. The locking block further squeezes the locking pin, completely retracting it into the shrinking component. Connecting pipe (second type) can then be slid off, separating the oil pipe connector. After inspection, simply re-move the threaded pipe and threaded groove until the sealing ring contacts connecting pipe (first type), and the locking pin engages in the locking hole to complete the sealing connection. This facilitates disassembly and inspection of the high-pressure oil pipe connector by maintenance personnel, improving maintenance efficiency.

[0017] 2. This utility model provides a high-pressure oil pipe connector. Through the cooperation of a wire-drawing interface, a rotating shaft, a second annular locking block, a first connector, and a second connector, the oil pipe is threaded onto the outer wall of the wire-drawing interface. The rotating shaft and the second annular locking block fasten the oil pipe to the wire-drawing interface. A fixing screw is passed through the threaded connection between the first connector and the second connector to tighten it. The first and second annular locking blocks rotate around the rotating shaft and are locked together, so that the oil pipe and the wire-drawing interface are tightly connected. It can adapt to oil pipes of different sizes, facilitates operation, improves sealing performance, and prevents oil leakage.

[0018] 3. This utility model provides a high-pressure oil pipe connector. By using a hose and a metal tension tube in combination, when the oil pipe connectors are not in the same direction, the hose can be bent to drive the metal tension tube to extend and bend. This allows the oil pipe connector to connect two oil pipes that are not in the same parallel or perpendicular relationship and are tilted at different angles. The metal tension tube prevents the hose from being damaged by external forces, thus making the application range wider. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-4As shown, this utility model provides a high-pressure oil pipe connector, including a disconnection mechanism 1, a bending mechanism 2 at the top of the disconnection mechanism 1, and a connecting mechanism 3 at the top of the bending mechanism 2; the disconnection mechanism 1 includes a connecting pipe 11, the inner wall of the connecting pipe 11 has a threaded groove 12, the inner wall of the threaded groove 12 is threadedly connected to a threaded pipe 17, the top of the threaded pipe 17 is fixedly connected to a sealing ring 16, the bottom of the threaded pipe 17 is fixedly connected to a connecting pipe 18, the bottom of the connecting pipe 11 is fixedly connected to a locking block 14, the outer wall of the locking block 14 has a locking hole 13, the outer wall of the locking block 14 is slidably connected to a pressing member 15, the outer wall of the connecting pipe 18 is fixedly connected to a shrinking member 19, the inner wall of the shrinking member 19 is slidably connected to a locking pin 111, the bottom of the locking pin 111 is fixedly connected to a return spring 110, one end of the return spring 110 is fixedly connected to the shrinking member 19.

[0027] In this embodiment, when the oil pipe joint needs to be repaired and inspected, the extrusion member 15 is slid along the outer wall of the locking block 14, and the locking pin 111 is squeezed into the retracting member 19. The return spring 110 retracts, leaving only the round head of the locking pin 111 in the locking hole 13. The resistance is reduced, and the connecting pipe 11 and the connecting pipe 2 18 can be held and rotated to separate them. The threaded pipe 17 and the threaded groove 12 make threaded movements. The locking block 14 squeezes the locking pin 111 again and retracts it completely into the retracting member 19. The connecting pipe 2 18 can be slid off to separate the oil pipe joint. After the inspection is completed, the threaded pipe 17 only needs to make threaded movements with the threaded groove 12 again until the sealing ring 16 contacts the connecting pipe 11, and the locking pin 111 is locked into the locking hole 13 to complete the sealing connection.

[0028] Example 2

[0029] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the top of the connecting pipe 11 is fixedly connected to a flange 112, the bending mechanism 2 includes a flange 21, the bottom of the flange 21 is fixedly connected to the flange 112, the top of the flange 21 is fixedly connected to a hose 22, the outer wall of the hose 22 is sleeved with a metal stretch tube 23, and the bottom of the metal stretch tube 23 is fixedly connected to the flange 21.

[0030] In this embodiment, when the directions of the oil pipe joints are inconsistent, the flexible hose 22 can be bent to drive the metal tension tube 23 to extend and bend, so that the oil pipe joint can connect two oil pipes that are not in the same parallel or perpendicular relationship and are tilted at different angles. The metal tension tube 23 prevents the flexible hose 22 from being damaged by external forces.

[0031] Example 3

[0032] like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the connecting mechanism 3 includes a wire-drawing interface 31, the bottom of which is fixedly connected to the flexible tube 22, an annular locking block 32 is sleeved on the outer wall of the wire-drawing interface 31, a rotating shaft 33 is rotatably connected to one end of the annular locking block 32, a connector 35 is fixedly connected to the other end of the annular locking block 32, an annular locking block 34 is rotatably connected to the outer wall of the rotating shaft 33, and a connector 36 is fixedly connected to one end of the annular locking block 34.

[0033] In this embodiment, by threading the oil pipe onto the outer wall of the wire drawing interface 31, the rotating shaft 33 and the second annular locking block 34 are fastened to the oil pipe and the wire drawing interface 31. The fixing screw is threaded through the first connector 35 and the second connector 36 to tighten the connection, so that the first annular locking block 32 and the second annular locking block 34 rotate around the rotating shaft 33. By clamping the first annular locking block 32 and the second annular locking block 34, the oil pipe and the wire drawing interface 31 are tightly connected.

[0034] The working principle of this high-pressure oil pipe joint will be explained in detail below.

[0035] like Figure 1-4 As shown, by threading the oil pipe onto the outer wall of the wire drawing interface 31, the rotating shaft 33 and the second annular locking block 34 are fastened to the oil pipe and the wire drawing interface 31. A fixing screw is used to tighten the connection between the first connector 35 and the second connector 36, causing the first annular locking block 32 and the second annular locking block 34 to rotate around the rotating shaft 33. The oil pipe and the wire drawing interface 31 are tightly connected by the locking blocks 32 and 34. When maintenance or inspection of the oil pipe joint is required, the extrusion member 15 is slid along the outer wall of the locking block 14, squeezing the locking pin 111 into the retraction member 19. The return spring 110 retracts, leaving only the round head of the locking pin 111 in the locking hole 13. This reduces resistance, allowing the first connecting pipe 11 and the second connecting pipe 18 to be gripped and rotated. Separate the threaded tube 17 and the threaded groove 12 to make threaded movement. The locking block 14 squeezes the locking pin 111 again and retracts it completely into the shrinking part 19. The connecting tube 2 18 can be slid off to separate the oil pipe joint. After inspection, simply make the threaded tube 17 and the threaded groove 12 to make threaded movement until the sealing ring 16 contacts the connecting tube 1 11. The locking pin 111 is inserted into the locking hole 13 to complete the sealing connection. When the oil pipe joints are not in the same direction, the hose 22 can be bent to drive the metal tension tube 23 to extend and bend, so that the oil pipe joint can connect two oil pipes that are not in the same parallel or perpendicular relationship and are tilted at different angles. The metal tension tube 23 prevents the hose 22 from being damaged by external forces.

[0036] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
