Technical Field

[0001] The embodiment of the utility model relates to the technical field of cable couplings, and in particular to a wear-resistant self-tightening cable coupling. Background Art

[0002] In oil drilling workpieces, cables need to be fixed to prevent them from being worn and damaged during movement. Therefore, cable couplings are used to fix the cables. For example, as shown in the oil pipe coupling with Chinese patent application number CN202122432489.8, open clamping positioning couplings are fixedly installed at both ends of the inner cavity of the elastic metal open coupling, and an airbag-type sealing rubber sleeve located between the two open clamping positioning couplings is fixedly installed in the middle of the inner cavity of the elastic metal open coupling.

[0003] However, when the air inlet valve is used to connect the inner cavity of the sealing airbag body to an external air source, and the external air source is allowed to inflate the inner cavity of the sealing airbag body to expand its volume to fill the connecting gap of the oil pipe, the sealing airbag body will be damaged when the cable coupling is in use, causing the cable coupling to be offset and damaged. Utility Model Content

[0004] To this end, an embodiment of the present invention provides a wear-resistant self-tightening cable coupling to solve the problem in the prior art that an air intake valve is used to connect the inner cavity of the sealing airbag body to an external air source, allowing the external air source to inflate the inner cavity of the sealing airbag body to expand its volume to fill the connecting gap of the oil pipe. When the cable coupling is in use, the sealing airbag body will be damaged, causing the cable coupling to be offset and damaged.

[0010] Furthermore, the cable coupling assembly 1 includes a cable coupling 1 hinged to a cable coupling 2, and a through hole 1 is provided at the bottom end of the cable coupling 1 for cooperating with the through hole 2 to fix the cable coupling 1 and the cable coupling 2.

[0011] Furthermore, a hinge block for rotation is movably connected in the through hole 1, and a bolt for inserting into the cable coupling 2 is fixedly installed at the bottom end of the hinge block.

[0012] Furthermore, a nut for fixing the first cable coupling and the second cable coupling is screwed onto the rod of the bolt, a gasket is provided on the top of the nut, and the gasket is sleeved on the bolt.

[0013] Furthermore, the locking assembly includes a locking plate for locking the second through hole, and there are four locking plates. A movable plate for driving the locking plate to move in the placement slot is fixedly installed at the rear end of the locking plate.

[0031] See also Figures 1-6 The utility model provides a wear-resistant self-tightening cable coupling.

[0032] The utility model comprises a base 100 , a top end of which is provided with a cable coupling body 200 for fixing the cable, and a self-locking device 300 for self-locking the cable coupling body 200 is provided in the cable coupling body 200 .

[0035] The cable coupling assembly 210 includes a cable coupling 211 hinged to a cable coupling 221, and a silicon carbide wear-resistant coating is sprayed on the cable coupling 211 to extend the service life of the cable coupling 211; the bottom end of the cable coupling 211 is provided with a through hole 216 for cooperating with the through hole 222 to fix the cable coupling 211 and the cable coupling 221, and there are four through holes 216, and the four through holes 216 are distributed in a linear array at the top of the cable coupling 211, and the axis of the through hole 216 is the same as the axis of the through hole 222.

[0036] A hinge block 212 for rotation is movably connected in the through hole 1 216, and a bolt 213 for inserting into the cable coupling 2 221 is fixedly installed at the bottom end of the hinge block 212. A nut 215 for fixing the cable coupling 1 211 and the cable coupling 2 221 is screwed on the rod body of the bolt 213. A gasket 214 is provided on the top of the nut 215, and the gasket 214 is sleeved on the bolt 213; so that when it is necessary to fix the cable used in the oil field and oil well, the cable can be placed in the cable coupling. Then, the cable coupling 1 211 is moved downward around the cable coupling 2 221 so that the bolt 213 at the bottom end of the hinge block 212 passes through the through hole 1 216 and the through hole 2 222. Then, the gasket 214 is put on the bolt 213, and then the nut 215 is screwed onto the bolt 213, so that the cable coupling 1 211 and the cable coupling 2 221 can be fixed. Finally, the bolt 213 in the through hole 2 222 is locked by the self-locking device 300 to prevent the bolt 213 from deflecting.

[0037] The self-locking device 300 includes a locking assembly 320 for locking the cable coupling assembly 1 210 and the cable coupling assembly 2 220 . A driving assembly 310 for driving the locking assembly 320 to move left and right is provided on the left side of the locking assembly 320 .

[0039] The left end of the movable plate 321 is hinged with a connecting plate 313 for driving the movable plate 321 to move left and right, so that when the through hole 222 needs to be opened, the connecting plate 313 can be rotated around the movable plate 321, so that the connecting plate 313 and the movable plate 321 are in the same plane, and the movable plate 321 can be moved into the cable coupling 221, and the locking plate 322 can be moved away from the through hole 222 and opened.

[0040] The front end of the connecting plate 313 is fixedly installed with an operating plate 311 for driving the connecting plate 313 to move. The plate body of the operating plate 311 is provided with a locking rod 312 for locking the operating plate 311. There are two locking rods 312, and the two locking rods 312 are symmetrically distributed on the plate body of the operating plate 311. Therefore, when it is necessary to fix the cable used in the oil field and oil well, the cable can be put into the cable coupling 221, and then the cable coupling 1 211 is moved downward around the cable coupling 221, so that the bolt 213 at the bottom end of the hinge block 212 passes through the through hole 1 216 and the through hole 222, and then the gasket 214 is put on the bolt 213, and then After that, the nut 215 is screwed onto the bolt 213 to fix the cable coupling 1 211 and the cable coupling 2 221. Then, the movable plate 321 controls the locking plate 322 to move to the left, and the locking plate 322 is pressed against the inner wall of the through hole 222. Finally, the connecting plate 313 is moved around the movable plate 321 to approach the cable coupling 2 221, so that the two locking rods 312 pass through the operating plate 311 and are screwed into the cable coupling 2 221. This locks the movable plate 321 to prevent the bolt 213 from deviating, resulting in incomplete connection between the cable coupling 1 211 and the cable coupling 2 221, thereby causing the cable used in the oil field and oil well to deviate.

Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
