Detailed Description
Fig. 1 is a schematic mechanism diagram of the quick coupling for hard pipes of the present invention. As shown in the figure, the utility model comprises a locking pipe handle 2, a left joint 3, a spring 5, a pressing pin shaft 6, a step pin shaft 7, a right joint 9 and a rubber sealing sleeve 11; the lock pipe handle 2 is provided with an external thread; the left connector 3 is provided with an internal threaded hole, the locking pipe handle 2 is connected to the internal threaded hole through threads, the left connector 3 is also provided with a through hole I12, a sliding hole 14 and a clamping hole 4, and the clamping hole 4 is positioned on the sliding hole 14; the right joint 9 is provided with a pressing hole, the pressing pin shaft 6 is arranged in the pressing hole of the right joint 9 to form a moving pair, the right joint 9 is also provided with a step 8 and a through hole II 10, and the step 8 on the right joint 9 is arranged in a sliding hole 14 of the left joint 3 to form a moving pair; the spring 5 and the step pin shaft 7 are arranged in the clamping hole 4 on the left connector 3, one end of the spring 5 props against the step pin shaft 7, the other end of the spring props against the left connector 3, the step pin shaft 7 and the left connector 3 form a moving pair, and one end of the spring is propped against a step 8 on the right connector 9 under the action of the spring 5; the pressing pin shaft 6 is arranged in a pressing hole of the right joint 9 to form a sliding pair, and the pressing pin shaft 6 is abutted with the left joint 3 through an inclined plane; the rubber sealing sleeve 11 is provided with a third through hole, a step 13 is arranged on the third through hole, and the rubber sealing sleeve 11 is arranged in the first through hole 12 of the left joint 3 and the second through hole 10 of the right joint 9.
The utility model discloses a work like this: the pipe 1 to be connected is inserted into the first through hole 12 of the left joint 3 and the second through hole 10 of the right joint 9 respectively, the pipe 1 to be connected abuts against the step 13 on the rubber sealing sleeve 11, the pipe locking handle 2 is screwed in to abut against the pipe 1, the pipe 1 to be connected with the left side is fixedly connected with the left joint 3, one end of the step pin shaft 7 abuts against the step 8 on the right joint 9 under the action of the spring 5, the left joint 3 and the right joint 9 are drawn close to each other, the left joint 3 presses the pressing pin shaft 6 downwards through the inclined plane to press the pipe 1, the pipe 1 to be connected with the right side is fixedly connected with the right joint 9, and the pipe 1 to be connected is drawn close to the rubber sealing sleeve 10 to be sealed. When the left joint 3 and the right joint 9 are drawn close, one end of the step pin shaft 7 pushes against the step 8 on the right joint 9 to move relatively until one end of the step pin shaft 7 falls off from the step 8 on the right joint 9 to be clamped and limited. When the pipe is disassembled, the pipe can be disassembled by pulling the stepped pin shaft 7 to return to the step 8 of the right connector 9 and unscrewing the locking pipe handle 2.
In addition to the above embodiments, the present invention has other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
