Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a hydraulic hose dismounting device comprises a hose 4 and a connector installed at one end of the hose 4, wherein the connector comprises a fixed sleeve 1, a connecting pipe 2 fixed inside the fixed sleeve 1, a pipe nut 3 movably sleeved outside the fixed sleeve 1, a lock nut 5 in threaded sleeve connection with the outside of the fixed sleeve 1, and a plurality of pressing plates 8 fixed at one end of the fixed sleeve 1, and the pipe nut 3 is used for connecting the connector with an oil pipe of a hydraulic machine;

one end of the connecting pipe 2 is inserted into the hose 4, the pressing plates 8 are located at one end of the fixing sleeve 1 far away from the pipe nut 3, the pressing plates 8 are located outside the hose 4, the lock nut 5 is located outside the pressing plates 8, the inner ring of the lock nut 5 abuts against the outer walls of the pressing plates 8, the connector further comprises a non-slip mat 7 fixed on the inner wall of the pressing plates 8, the non-slip mat 7 abuts against the outer wall of the hose 4, the pressing plates 8 are elastic iron sheets, the pressing plates 8 are tightly tightened and furled through the lock nut 5, so that the non-slip mat 7 on the pressing plates 8 is tightly pressed on the outer wall of the hose 4, the connector and the hose can be tightly fixed together, after the lock nut 5 is moved away from the pressing plates 8, the pressing plates 8 can automatically bounce, so that the non-slip mat 7 is not contacted with the outer wall of the hose 4, and then the connecting pipe 2 can be drawn out of the hose 4, the connector can be conveniently disassembled;

a locking device for placing the locking nut 5 to be loosened is arranged between the locking nut 5 and the connecting pipe 2, the locking device consists of an accommodating hole 13 arranged on the outer wall of the fixed sleeve 1, a limiting block 12 arranged inside the accommodating hole 13, a limiting hole 11 arranged on the inner wall of the locking nut 5, a mounting hole 10 arranged on the outer wall of the locking nut 5 and a locking bolt 9 in threaded connection with the bottom of the mounting hole 10, one end of the locking bolt 9 extends to the inside of the limiting hole 11, the limiting block 12 is matched with the limiting hole 11, a spring is fixed on the inner wall of the bottom of the accommodating hole 13, the other end of the spring is fixedly connected with the bottom of the limiting block 12, and the locking device can ensure that the locking nut 5 cannot rotate after being locked, thereby ensuring that the pressure plate 8 can be tightly arranged in the locking nut 5, and further ensuring that the connection between the connector and the hose 4 cannot be loosened;

the outer ring of the limiting block 12 is in contact with the inner ring of the accommodating hole 13, so that the limiting block 12 can be prevented from shaking in the accommodating hole 13;

the inner ring of the opening of the lock nut 5 is provided with a chamfer, and the chamfer can facilitate the plurality of press plates 8 to be conveniently retracted into the lock nut 5 when the plurality of press plates 8 are tightened;

a plurality of anti-slip strips 6 are fixed on the outer ring of the locking nut 5, the anti-slip strips 6 are convenient to rotate the locking nut 5, and hand slipping of an operator is avoided.

The working principle is as follows: when the connector is disassembled, the locking bolt 9 is screwed by a screwdriver, so that the locking bolt 9 ejects the limit block 12 to the outside of the limit hole 11, when the bolt head of the locking bolt 9 abuts against the bottom of the mounting hole 10, the limit block 12 is just ejected to the outside of the limit hole 11 completely and enters the inside of the receiving hole 13, in this way, the locking nut 5 can be unscrewed, so that the locking nut 5 gradually approaches to the pipe nut 3, so that the pressure plate 8 gradually exposes from the inside of the locking nut 5, at this time, the limit block 12 is still in the locking nut 5, the top of the limit block 12 abuts against the inner ring of the locking nut 5, the spring is also in a compressed state, after the compression of the locking nut 5 is lost, the anti-skid pad 7 on the pressure plate 8 loses the compression on the hose 4, and then the connecting pipe 2 can be taken out from the hose 4, then cut off the problematic part on the hose 4, then just can insert the inside of hose 4 after the renovation again with connecting pipe 2, loosen locking bolt 9 with the screwdriver next time, then tighten lock nut 5 again, thereby compress tightly again and draw in a plurality of clamp plates 8, make slipmat 7 tightly press on the outer wall of hose 4, after stopper 12 is just right with spacing hole 11, under the effect of spring, the inside of spacing hole 11 can be blocked into to the one end of stopper 12, lock nut 5 just can't be rotated again, thereby the installation between connector and the hose has been given to accomplish, then just can be in the same place with oil pipe connection on the hydraulic press with pipe nut 3.
