then, the second corrugated tube 1 is inserted into the through hole on the side of the connecting tube 2 close to the second fixing ring 8, and passes through the through hole on the second moving plate 9, and abuts against one end of the first corrugated tube 1, then the second rotating ring 7 is rotated, the second sliding sleeve 6 is driven to slide along the outer wall of the connecting tube 2 through threaded connection, then the second sliding sleeve 6 drives the second moving plate 9 to move in the direction close to the first moving plate 11 through the connecting block 29, then the first moving plate 11 drives the second clamping plate 15 to move together through the mounting block 20, due to the inclined plane effect between the first wedge plate 14 and the second clamping plate 15, the second clamping plate 15 moves in the direction close to the corrugated tube 1 during moving, and simultaneously the corrugation on the outer wall of the corrugated tube 1 is inserted into the groove on the outer wall of the second clamping plate 15, thereby fixing the second corrugated tube 1 is completed, and simultaneously, the second clamping plate 15 moves in the direction of the first moving plate 11 while moving to the corrugated tube 1 Therefore, the second clamping plate 15 can drive the corrugated pipe 1 to move towards the first corrugated pipe 1 after contacting the corrugated pipe 1, so that the contact between the first corrugated pipe 1 and the second corrugated pipe 1 can be tighter, and meanwhile, as the first rotating ring 4 and the first sliding sleeve 5 and the second rotating ring 7 and the second sliding sleeve 6 are in threaded connection, a self-locking effect can be achieved after the second moving plate 9 and the first moving plate 11 move, so that the stability of fixing the first corrugated pipe 1 and the second corrugated pipe 1 is improved;
then, the corrugated pipes 1 can be unlocked by reversely rotating the second rotating ring 7 and the first rotating ring 4, so that the effects of convenient disassembly and connection when the two corrugated pipes 1 are connected are achieved, the operation is convenient, and the time is saved.
When the second moving plate 9 and the first moving plate 11 move, the second sliding block 22 is driven to slide along the inner wall of the second sliding groove 21, and when the second moving plate 9 moves towards the direction close to the first moving plate 11, the push rod 24 drives the fixture block 28 to move together, because the inclined plane between the triangular inclined groove 23 and the fixture block 28 is matched, the fixture block 28 is separated from the triangular inclined groove 23, because the first clamping plate 13 rotates through the connecting rod 12 to make the first clamping plate 13 slide towards the corrugated pipe 1, and because the second clamping plate 15 and the first wedge plate 14 are matched through the inclined plane to make the second clamping plate 15 slide towards the corrugated pipe 1, when the first clamping plate 13 and the second clamping plate 15 are both attached to the outer wall of the corrugated pipe 1, the distance that the second moving plate 9 needs to move is longer than the distance that the first moving plate 11 moves, so the fixture block 28 is inserted into the clamping groove 16 formed in the outer wall of the first moving plate 11, therefore, the second corrugated pipe 1 can be fixed and the first moving plate 11 can be limited through the sequential installation sequence, so that the first corrugated pipe 1 can be further limited, the stability of the first corrugated pipe 1 in the fixing process is improved, when one corrugated pipe 1 is in the fixed state, the first corrugated pipe 1 can be inserted into the connecting pipe 2 for connection, the stability in the connection process can be improved, and if the second corrugated pipe 1 and the connecting pipe 2 bear great tensile force, the connecting pipe 2 can be pulled out more and more under the action of the connecting rod 12, so that the first clamping plate 13 clamps the corrugated pipe 1 more and more tightly, the bearing capacity of the first corrugated pipe 1 is improved, the connection is more stable, and in the same way, when the second corrugated pipe 1 bears great tensile force, the corrugated pipe 1 can drive the second clamping plate 15 to move, and the second clamping plate is pulled more and more tightly under the action of the inclined surface of the first wedge plate 14, so that the dragging-breaking prevention effect is achieved to a great extent.
Meanwhile, the sealing ring 10 is extruded when the second moving plate 9 moves towards the first moving plate 11, and the sealing ring 10 is extruded to deform, so that the inner diameter of the sealing ring 10 is in contact with and attached to the two corrugated pipes 1, a sealing effect can be achieved at the joint of the two corrugated pipes 1, and the two corrugated pipes 1 can be tightly connected.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
