The other ends of the single-well metering pipeline 3, the high-pressure production pipeline 4, the low-pressure production pipeline 5, and the venting pipeline 6 are respectively connected to the single-well metering manifold, the high-pressure production manifold, the low-pressure production manifold, and the venting manifold. The plurality of valves 7 are respectively arranged on the main pipeline 1, the air intake pipeline 2, the single-well metering pipeline 3, the high-pressure production pipeline 4, the low-pressure production pipeline 5, and the venting pipeline 6. Three branch pipes 8 are sealedly installed on the inner wall of the peripheral side of the main pipeline 1. Four card grooves are provided on the outer walls of the peripheral sides of the three branch pipes 8. The three branch pipes 8 are respectively carded and installed in the single-well metering pipeline 3, the high-pressure production pipeline 4, and the low-pressure production pipeline 5 through a card connection component. The card connection component comprises a square card plate 9. Four square sliding holes are provided in the square card plate 9. The four square sliding holes are each carded by a sliding single A trapezoidal card block 10 is slidably installed on the element, and four trapezoidal card blocks 10 extend into four card slots respectively.

A round cavity is provided in the square card plate 9, and the round cavity is connected with the four square sliding holes. Two rotating shafts 15 are installed on the relative inner walls of the round cavity for common rotation. Four spacers 16 are fixedly installed in the round cavity, and mounting holes are provided on the sides of the four spacers 16. Two rotating rods 17 are installed in the four mounting holes respectively. The two rotating shafts 15 are connected with the two rotating rods 17 through a transmission unit. The two rotating shafts 15 and the two rotating rods 17 are provided with linkage units adapted to the trapezoidal card block 10.

Rotating rings 27 are installed on the intake pipe 2 and the vent pipe 6 through a moving component, and the two rotating rings 27 are provided with a clamping component adapted to the main pipe 1.

[0029] With the above structure, when using, when installing the main line 1, the air intake line 2 and the vent line 6, first insert the two ends of the main line 1 into the air intake line 2 and the vent line 6 respectively to achieve the sealing function, and then fix them by clamping them through the clamping assembly. When it is necessary to connect the main pipe 1, the single well metering pipe 3, the high-pressure production pipe 4, and the low-pressure production pipe 5, the three branch pipes 8 are respectively sleeved on the single well metering pipe 3, the high-pressure production pipe 4, and the low-pressure production pipe 5, and then the main pipe 1 is pressed downward to drive the branch pipe 8 to move downward under the extrusion effect. When the branch pipe 8 contacts the four trapezoidal blocks 10, the four trapezoidal blocks 10 are driven to move synchronously away from the axis under the extrusion effect. When the branch pipe 8 continues to move downward to a suitable position, the four trapezoidal blocks 10 are driven to reset under the action of the reset unit, and the fixing function of the branch pipe 8 is realized through the clamping function of the four blocks and the four clamping grooves. When disassembly is required, it is only necessary to rotate the operating unit counterclockwise to drive one of the rotating shafts 15 to rotate counterclockwise, and then the four trapezoidal blocks 10 are driven to move synchronously away from the axis under the joint action of the transmission unit and the linkage unit, and then the clamping fixation with the four clamping grooves is released to realize the disassembly function.

[0030] like Figure 3 As shown, the sliding unit includes two rectangular sliders 11, and the relative inner walls of the square sliders are provided with sliding grooves. The two rectangular sliders 11 are slidably installed in the two sliding grooves respectively, and the two side portions of the trapezoidal block 10 are fixedly connected to the relative side portions of the two rectangular sliders 11.

[0033] like Figure 3 As shown, the transmission unit includes two first bevel gears 18 and two second bevel gears 19. The two first bevel gears 18 are fixedly sleeved on the two rotating shafts 15 respectively, and the two second bevel gears 19 are fixedly sleeved on one of the rotating rods 17. The two first bevel gears 18 are respectively meshed and installed with the two second bevel gears 19. The advantage of such an arrangement is that, through the arrangement of the two first bevel gears 18 and the two second bevel gears 19, the two rotating shafts 15 can be linked, so that when one of the rotating shafts 15 is rotated, the other rotating shaft 15 can be driven to rotate in the opposite direction.

[0034] like Figure 6 As shown, the transmission unit also includes two third bevel gears 24 and two fourth bevel gears 25. The two third bevel gears 24 are fixedly sleeved on the two rotating shafts 15, respectively. The two fourth bevel gears 25 are fixedly sleeved on another rotating rod 17. The two third bevel gears 24 are respectively meshed and installed with the two fourth bevel gears 25. The advantage of such an arrangement is that, through the arrangement of the two third bevel gears 24 and the two fourth bevel gears 25, the two rotating rods 17 can be linked, so that when one of the rotating rods 17 rotates, the other rotating rod 17 can be driven to rotate in the opposite direction.

[0035] like Figure 3 As shown, the linkage unit includes four gears 20 and four racks 21. The four gears 20 are fixedly sleeved on two rotating shafts 15 and two rotating rods 17 respectively. The four racks 21 are fixedly installed on the bottoms of four trapezoidal blocks 10 respectively. The four gears 20 are meshed with the four racks 21 respectively. The advantage of such a setting is that, through the setting of the four gears 20 and the four racks 21, when the two rotating shafts 15 and the two rotating rods 17 are rotating, the four gears 20 can be driven to rotate synchronously, and the trapezoidal block 10 can be controlled through the meshing action of the four gears 20 and the four racks 21.

[0036] like Figure 3 As shown, the operating unit includes a knob 22, the end of which is connected to the end of one of the rotating shafts 15, and a plurality of anti-slip strips 23 are evenly arranged on the outer wall of the circumference of the knob 22. The advantage of such a setting is that, through the setting of the knob 22, when the staff needs to rotate the rotating shaft 15, convenient operation can be achieved by rotating the knob 22, and the operation is more convenient.

[0037] like Figure 5As shown, the moving assembly includes a thread groove 26, the outer walls of the intake pipe 2 and the exhaust pipe 6 are provided with a thread groove 26, and the inner walls of the two rotating rings 27 are provided with internal threads, and the two internal threads are respectively matched with the two thread grooves 26. The advantage of such a setting is that the internal threads and the thread grooves 26 can realize the moving function of the rotating ring 27 on the intake pipe 2 and the exhaust pipe 6.

[0038] like Figure 5 As shown, the clamping assembly includes an annular plate 28, a fixed ring 29, and a mounting ring 30. The annular plate 28 is rotatably mounted on the peripheral outer wall of the rotating ring 27. The fixed ring 29 is fixedly sleeved on the main pipeline 1. The peripheral outer wall of the fixed ring 29 is provided with four buckle grooves. The mounting ring 30 is fixedly sleeved on the intake pipeline 2 or the venting pipeline 6. The peripheral outer wall of the mounting ring 30 is provided with four rotating grooves. The relative inner walls of the four rotating grooves are rotatably mounted with fixing hooks 31. The four fixing hooks 31 are respectively adapted to the four buckle grooves. The four fixing hooks 31 are all connected to the annular plate 28 through a connecting unit, and the connecting unit includes a connecting rod 32, one end of the connecting rod 32 is rotatably installed on the side of the annular plate 28, and the other end of the connecting rod 32 is rotatably installed on the side of the fixing hook 31. The advantage of such a setting is that through the setting of the annular plate 28, the fixing ring 29, and the mounting ring 30, the control function of the fixing hook 31 can be realized, so that the fixing hook 31 can be snapped into the snap groove, thereby realizing the fixed installation function, and the fixing effect is good and the practicability is strong.

[0039] Working principle of the present invention: when installing the main pipeline 1, the air intake pipeline 2 and the vent pipeline 6, firstly, insert the two ends of the main pipeline 1 into the air intake pipeline 2 and the vent pipeline 6 respectively to realize the sealing function, and then rotate the two rotating rings 27 respectively. When the rotating ring 27 rotates, the rotating ring 27 moves toward the main pipeline 1 under the action of the threaded groove 26, and drives the annular plate 28 to move synchronously at the same time. Under the action of the four connecting rods 32, the four fixing hooks 31 are driven to turn toward the axis synchronously, and realize the clamping and fixing function with the four snap grooves respectively. With this arrangement, when the main pipeline needs to be installed, the fixing and clamping function can be realized by rotating the rotating ring 27, and since the threaded connection has strong stability, the fixing hook 31 will not turn over, and the fixing effect is better. When it is necessary to connect the main pipe 1, the single well metering pipe 3, the high-pressure production pipe 4, and the low-pressure production pipe 5, it is only necessary to respectively sleeve the three branch pipes 8 on the outside of the single well metering pipe 3, the high-pressure production pipe 4, and the low-pressure production pipe 5, and then press the main pipe 1 downward to drive the branch pipe 8 to move downward under the extrusion effect. When the branch pipe 8 contacts the four trapezoidal blocks 10, the four trapezoidal blocks 10 are driven to move synchronously away from the axis under the extrusion effect. When the branch pipe 8 continues to move downward to a suitable position, the four trapezoidal blocks 10 are reset under the elastic action of the four reset springs 14, and the fixing function of the branch pipe 8 is realized through the clamping function of the four blocks and the four slots. In this way, multiple branch pipes 8 can be fixed at the same time without separate installation. The installation is more efficient, the fixing operation is convenient, and the effect is better. When disassembly is required, it is only necessary to rotate the knob 22 counterclockwise to drive one of the rotating shafts 15 to rotate counterclockwise, and then drive the other rotating shaft 15 to rotate in the opposite direction under the action of one of the rotating rods 17, the two first bevel gears 18 and the two second bevel gears 19, and at the same time, the two rotating rods 17 are driven to rotate in the opposite direction synchronously under the action of the two third bevel gears 24 and the two fourth bevel gears 25, and the four trapezoidal blocks 10 are driven to move synchronously away from the axis through the meshing action of the four gears 20 and the four racks 21, thereby releasing the clamping fixation with the four card slots to realize the disassembly function. In this way, the branch pipe 8 can be quickly disassembled, and the disassembly operation is simple, time-saving and labor-saving, and highly practical.
