Described pipe joint comprises elastic little lasso and large lasso, and described little lasso is roundRing-type, described large lasso is oval ring-type, and little lasso and large lasso coaxially arrange, and described littleThe both sides of lasso are connected respectively with the two ends of the major axis of large lasso by shell fragment;
Little lasso is set on tube connector and by fixture to be fixed, described fixture bagDraw together the circle plush copper on the circle axial gap of one on little lasso inner face and tube connector, described plush copperInsert in described breach and the outer face of little lasso is pushed against on the first collar flange, described theOne collar flange is arranged on described tube connector;
It is upper that large lasso is set in female pipe, and female pipe is provided with the second collar flange for locating, instituteThe length of stating the major axis of large lasso is greater than the external diameter of the second collar flange, and the length of minor axis is less thanThe external diameter of two collar flanges.
Further, described sealing ring is arranged in the annular groove on tube connector.
Further, described little lasso is provided with 2 symmetrical breach, on described tube connector, establishesThere are 2 symmetrical plush coppers.
Further, described the second collar flange is near the openend of female pipe.
The invention has the beneficial effects as follows:
1, easy installation and removal, without using any instrument, operator utilizes the both hands can be completeBecome installing/dismounting;
2, installation, dismounting and maintenance efficiency have been promoted, without the length of adjusting flexible pipe insertion hard tubeDegree, without the clamping position of adjusting clip, convenient and swift;
3, simple to operate, staff is without training.

Detailed description of the invention
With reference to accompanying drawing, a kind of pipe connecting structure, comprises that two mothers of needs docking manage 4, twoIndividual female pipe 4 is connected by connector;
Described connector comprises tube connector 2 and is set in the pipe joint 1 at tube connector 2 two ends, instituteThe two ends of stating tube connector 2 are plugged in respectively in two female pipes 4, and the two ends of described tube connector 2Be equipped with sealing ring 3 managing 4 junction with mother;
Described pipe joint 1 comprises elastic little lasso 11 and large lasso 12, described little coverCircle 11 is circular, and described large lasso 12 is oval ring-type, little lasso 11 and large lasso 12Coaxial setting, and the both sides of described little lasso 12 are by the major axis of shell fragment 13 and large lasso 12Two ends be respectively connected;
Little lasso 11 is set on tube connector 2 and by fixture to be fixed, described fixing dressPut the circle comprising on the circle axial gap 111 of one on little lasso 11 inner faces and tube connector 2Plush copper 22, described plush copper 22 is inserted in described breach 111 and the outer face of little lasso 11 is supportedTightly, on the first collar flange 21, described the first collar flange 21 is arranged on described tube connector 2On;
Large lasso 12 is set on female pipe 4, female pipe 4 the second ring-types that are provided with for locatingFlange 41, the length of the major axis of described large lasso 12 is greater than the external diameter of the second collar flange 41,The length of minor axis is less than the external diameter of the second collar flange 41.
Described sealing ring 3 is arranged in the annular groove on tube connector 2.
Described little lasso 11 is provided with 2 symmetrical breach 111, and described tube connector 2 is provided with2 symmetrical plush coppers 22.
Described the second collar flange 41 is near the openend of female pipe 4.
Operation principle of the present invention is:
Pipe joint 1 is connected the used of female pipe 4 with 2 of tube connectors, wherein pipe joint rises and connects motherThe effect of pipe 4 and tube connector 2; The little lasso 11 of pipe joint 1 is enclosed within on tube connector 2, largeLasso 12 is enclosed within on female pipe.
Notch alignment plush copper 22 on tube connector 2 is inserted on described tube connector 2, when plush copper 22After insertion breach 111 is interior, little lasso 11 is fixed on described plush copper 22 and described the first ring-type is protrudingBetween edge 21, the external diameter of tube connector 2 equates with the internal diameter of little lasso 11, but due to little lasso11 have certain elasticity, and the existence of breach 111, make little lasso have certain distortion skyBetween, be convenient to little lasso 11 and be enclosed within on described tube connector 2.
After little lasso is fixed on tube connector 2, tube connector 2 is inserted in female pipe 4, press bulletSheet 13, the major axis ((being the distance between AB)) of large lasso 12 diminishes, and minor axis (is CDBetween distance) become large, until the minor axis of large lasso is greater than the second collar flange on female pipe 4When 41 external diameter, large lasso 12 is through the second collar flange 41 and be enclosed within on female pipe 4, stopsOnly push shrapnel 13, large lasso 13 restores to the original state, and minor axis length is less than the second collar flange 41External diameter, the second collar flange 41 plays position-limiting action, large lasso 13 can not managed 4 from motherSlippage, two female pipes 4 effectively connect by connector, and female pipe 4 is logical with the junction of tube connector 2Crossing sealing ring 3 seals.
In like manner, in the time of the large lasso 12 of dismounting and tube connector 2, push shrapnel 13, when large lassoWhen 12 minor axis is greater than the external diameter of the second collar flange 41 on female pipe 4, large lasso 12 passesThe second collar flange 41 is managed 4 from mother and is taken off, and now, extracts tube connector 2 out. DismountingWhen little lasso 11 and tube connector 2, make breach 111 on little lasso 11 along plush copper 22 fromOn tube connector 2, take off.
Content described in this description embodiment is only the row of the way of realization to inventive conceptLift, protection scope of the present invention should not be regarded as only limiting to the concrete shape that embodiment statesFormula, protection scope of the present invention also comprise those skilled in the art conceive according to the present invention institute canThe equivalent technologies means of expecting.
