Described pipe joint comprises elastic little lasso and large lasso, and described little lasso is circular, and described large lasso is oval ring-type, and little lasso and large lasso are coaxially arranged, and the both sides of described little lasso are connected respectively by the two ends of shell fragment with the major axis of large lasso;
Little lasso to be set on connecting tube and to be fixed by fixing device, described fixing device comprises the circle axial gap on little lasso interior edge face and the circle plush copper on connecting tube, described plush copper to be inserted in described breach and is pushed against on collar flange by the exterior edge face of little lasso, and described collar flange is arranged on described connecting tube;
Two of female pipe is the mounting pipe matched with large lasso, and large lasso is set in mounting pipe, and the both sides of mounting pipe are radially arranged with two grooves, and the length of the major axis of described large lasso is greater than the external diameter of mounting pipe, and the length of minor axis is less than the external diameter of mounting pipe.
Further, described seal ring is arranged in the annular groove on connecting tube.
Further, described little lasso is provided with 2 symmetrical breach, and described connecting tube is provided with 2 symmetrical plush coppers.
The invention has the beneficial effects as follows:
1, easy installation and removal, without the need to using any instrument, operator utilizes both hands to complete installing/dismounting;
2, improving installation, dismounting and maintenance efficiency, inserting the length of hard tube without the need to adjusting flexible pipe, without the need to adjusting the clamping position of clip, convenient and swift;
3, simple to operate, staff is without the need to training.

Embodiment
With reference to accompanying drawing, pipe connecting structure, two female pipes, 4, two the female pipes 4 comprising needs docking are connected by link;
Described link comprises connecting tube 2 and is set in the pipe joint 1 at connecting tube 2 two ends, and the two ends of described connecting tube 2 are plugged in two female pipes 4 respectively, and the two ends of described connecting tube 2 are equipped with seal ring 3 in the joint with female pipe 4;
Described pipe joint 1 comprises elastic little lasso 11 and large lasso 12, described little lasso 11 is in circular, described large lasso 12 is in oval ring-type, and little lasso 11 and large lasso 12 are coaxially arranged, and the both sides of described little lasso 12 are connected respectively by the two ends of shell fragment 13 with the major axis of large lasso 12;
Little lasso 11 to be set on connecting tube 2 and to be fixed by fixing device, described fixing device comprises the circle axial gap 111 on little lasso 11 interior edge face and the circle plush copper 22 on connecting tube 2, described plush copper 22 to be inserted in described breach 111 and is pushed against on collar flange 21 by the exterior edge face of little lasso 11, and described collar flange 21 is arranged on described connecting tube 2;
Two of female pipe 4 is the mounting pipe matched with large lasso 12, large lasso 12 is set in mounting pipe, the both sides of described mounting pipe are radially arranged with two grooves 42, and the length of the major axis of described large lasso 12 is greater than the external diameter of mounting pipe, and the length of minor axis is less than the external diameter of mounting pipe.
Described seal ring 3 is arranged in the annular groove on connecting tube 2.
Described little lasso 11 is provided with 2 symmetrical breach 111, and described connecting tube 2 is provided with 2 symmetrical plush coppers 22.
Working principle of the present invention is:
Pipe joint 1 is connected the used of female pipe 4 with connecting tube 2, and wherein pipe joint plays a part to connect female pipe 4 and connecting tube 2; The little lasso 11 of pipe joint 1 is enclosed within connecting tube 2, and large lasso 12 is enclosed within female pipe.
Notch alignment plush copper 22 on connecting tube 2 is inserted on described connecting tube 2, when plush copper 22 is inserted after in breach 111, little lasso 11 is fixed between described plush copper 22 and described collar flange 21, the external diameter of connecting tube 2 is equal with the internal diameter of little lasso 11, but because little lasso 11 has certain elasticity, and the existence of breach 111, make little lasso have certain deformation space, be convenient to little lasso 11 and be enclosed within described connecting tube 2.
Little lasso is fixed on after on connecting tube 2, with the two ends alignment indentation 42 of large lasso 12 minor axis, connecting tube 2 is inserted in female pipe 4, push shrapnel 13, the major axis ((distance namely between AB)) of large lasso 12 diminishes, minor axis (distance namely between CD) becomes large, until when the minor axis of large lasso 12 is greater than the external diameter of mounting pipe, large lasso 12 can be enclosed within mounting pipe, namely large lasso is fixed on female pipe 4, when the two ends of minor axis fall in groove 42, stop pushing shrapnel 13, large lasso 13 restores to the original state, minor axis length is less than the external diameter of mounting pipe, groove 42 plays position-limiting action, large lasso 13 can not from slippage the mounting pipe of female pipe 4, two female pipes 4 are effectively connected by link, female pipe 4 is sealed by seal ring 3 with the joint of connecting tube 2.
In like manner, dismantle large lasso 12 and connecting tube 2 time, push shrapnel 13, when large lasso 12 minor axis be greater than the external diameter of mounting pipe time, large lasso can be taken off from female pipe 4, now, extract out connecting tube 2.When dismantling little lasso 11 and connecting tube 2, the breach 111 on little lasso 11 is taken off from connecting tube 2 along plush copper 22.
Content described in this specification embodiment is only enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as being only limitted to the concrete form that embodiment states, protection scope of the present invention also comprises those skilled in the art and conceives the equivalent technologies means that can expect according to the present invention.
