Described pipe joint includes elastic little lasso and big lasso, and described little lasso is circular, and described big lasso is in oval ring-type, and little lasso and big lasso are coaxially disposed, and the both sides of described little lasso are respectively connected with by the two ends of shell fragment Yu the major axis of big lasso；
Little lasso is set in connecting tube and is fixed by fixing device, described fixing device includes the circle axial gap on little lasso inner face and the circle plush copper in connecting tube, described plush copper is inserted in described breach and is pushed against on collar flange by the outer face of little lasso, and described collar flange is arranged in described connecting tube；
Two of female pipe is the installation pipe matched with big lasso, and big lasso is set on installation pipe, and the both sides installing pipe are radially arranged with two grooves, and the length of the major axis of described big lasso is more than the external diameter installing pipe, and the length of short axle is less than the external diameter installing pipe.
Further, described sealing ring is arranged in the annular groove in connecting tube.
Further, described little lasso is provided with 2 symmetrical breach, and described connecting tube is provided with 2 symmetrical plush coppers.
The beneficial effects of the utility model are:
1, easy installation and removal, it is not necessary to use any instrument, operator utilizes both hands can complete installing/dismounting；
2, installation, dismounting and maintenance efficiency are improved, it is not necessary to adjust flexible pipe and insert the length of hard tube, it is not necessary to adjust the clamping position of clip, convenient and swift；
3, simple to operate, staff is without training.

Detailed description of the invention
With reference to accompanying drawing, pipe connecting structure, including two the female pipes 4 needing docking, two female pipes 4 are connected by connector；
Described connector includes 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 sealing ring 3 in the junction with female pipe 4；
Described pipe joint 1 includes elastic little lasso 11 and big lasso 12, described little lasso 11 is in circular, described big lasso 12 is in oval ring-type, and little lasso 11 and big lasso 12 are coaxially disposed, and the both sides of described little lasso 12 are respectively connected with by the two ends of shell fragment 13 with the major axis of big lasso 12；
Little lasso 11 is set in connecting tube 2 and is fixed by fixing device, described fixing device includes the circle axial gap 111 on little lasso 11 inner face and the circle plush copper 22 in connecting tube 2, described plush copper 22 is inserted in described breach 111 and is pushed against on collar flange 21 by the outer face of little lasso 11, and described collar flange 21 is arranged in described connecting tube 2；
Two of female pipe 4 is the installation pipe matched with big lasso 12, big lasso 12 is set on installation pipe, the both sides of described installation pipe are radially arranged with two grooves 42, and the length of the major axis of described big lasso 12 is more than the external diameter installing pipe, and the length of short axle is less than the external diameter installing pipe.
Described sealing ring 3 is arranged in the annular groove in 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.
Operation principle of the present utility model is:
Pipe joint 1 and connecting tube 2 connect used by female pipe 4, and wherein pipe joint acts the effect connecting female pipe 4 and connecting tube 2；The little lasso 11 of pipe joint 1 is enclosed within connecting tube 2, and big lasso 12 is enclosed within female pipe.
Notch alignment plush copper 22 in connecting tube 2 is inserted in 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 owing to little lasso 11 has certain elasticity, and the existence of breach 111 so that little lasso has certain deformation space, it is simple to little lasso 11 is enclosed within described connecting tube 2.
After little lasso is fixed in connecting tube 2, two ends alignment indentation 42 with the big short axle of lasso 12, connecting tube 2 is inserted in female pipe 4, push shrapnel 13, the major axis ((i.e. distance between AB)) of big lasso 12 diminishes, short axle (i.e. distance between CD) becomes big, until the short axle of big lasso 12 is more than when installing the external diameter of pipe, big lasso 12 can be enclosed within installation pipe, namely big lasso is fixed on female pipe 4, when the two ends of short axle fall in groove 42, stop pushing shrapnel 13, big lasso 13 restores to the original state, minor axis length is less than the external diameter installing pipe, groove 42 plays position-limiting action, big lasso 13 will not slip from the installation pipe of female pipe 4, two female pipes 4 are effectively connected by connector, the junction of female pipe 4 and connecting tube 2 is sealed by sealing ring 3.
In like manner, dismantling big lasso 12 and during connecting tube 2, push shrapnel 13, when big lasso 12 short axle more than when installing the external diameter of pipe, big lasso can be taken off from female pipe 4, now, extracts connecting tube 2 out.When dismantling little lasso 11 and connecting tube 2, the breach 111 on little lasso 11 is made to take off connecting tube 2 along plush copper 22.
Content described in this specification embodiment is only enumerating of the way of realization to utility model design; protection domain of the present utility model is not construed as being only limitted to the concrete form that embodiment is stated, protection domain of the present utility model also include those skilled in the art according to this utility model design it is conceivable that equivalent technologies means.
