This utility model relates to a kind of assembling pipe joint.

Background technology

Along with the development of science and technology, the application of pipe-line system is more and more wider.Existing pipeline connection side Formula is generally clamping hoop type connection, bite type connection, bayonet joint and welding type and connects.Cutting ferrule Installing space and tube wall thickness be there are certain requirements by formula connection；Bayonet joint need to connect pipe end Molding is pre-machined；Welding type pipeline produces residual stress, and the tubing producing variations in temperature Flexible compensation performance is low；If it is not in place that clamping hoop type connects clip, easily occur revealing, and when peace Holding position and peripheral component produce when interfering, although rotate clip and can meet installation requirement, but Installation site is narrow sudden, dismounting clip it is necessary that with specific purpose tool, therefore above several pipelines company Connect and all there is the shortcoming that installing/dismounting is constant and wastes time and energy.

Summary of the invention

For solving the problems referred to above, the utility model proposes a kind of assembling pipe joint.

The technical solution adopted in the utility model is:

A kind of assembling pipe joint, including connecting tube and the pipe joint being set in connecting tube two ends, Described pipe joint includes elastic little lasso and big lasso, and described little lasso is circular, Described big lasso is ring-type in ellipse, and little lasso and big lasso are coaxially disposed, and described little lasso Both sides are respectively connected with by the two ends of shell fragment with the major axis of big lasso；

Little lasso is set in connecting tube and is fixed by fixing device, and described fixing device includes A circle axial gap on little lasso inner face and the circle plush copper in connecting tube, described plush copper is inserted Enter in described breach and the outer face of little lasso be pushed against on the first collar flange, described first Collar flange is arranged in described connecting tube.

Described little lasso is provided with 2 symmetrical breach, and described connecting tube is provided with 2 symmetries Plush copper.

The beneficial effects of the utility model are:

1, this utility model is utilized to carry out pipeline connection, easy installation and removal, it is not necessary to use and appoint What 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 Degree, 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

Referring to the drawings, a kind of assembling pipe joint, including connecting tube 2 be set in connecting tube 2 The pipe joint 1 at two ends, described pipe joint 1 includes elastic little lasso 11 and big lasso 12, described little lasso 11 is in circular, and described big lasso 12 is ring-type in ellipse, little lasso 11 and big lasso 12 be coaxially disposed, and the two ends of described little lasso 11 by shell fragment 13 with big The two ends of the major axis of lasso 13 are respectively connected with；

Little lasso 11 is set in connecting tube 2 and is fixed by fixing device, described fixing dress Put the circle on the circle axial gap 111 and connecting tube 2 included on little lasso 11 inner face Plush copper, in described plush copper inserts described breach and is pushed against first by the outer face of little lasso ring-type On flange, described first collar flange is arranged in described connecting tube.

Described little lasso is provided with 2 symmetrical breach, and described connecting tube is provided with 2 symmetries Plush copper.

Utilize the pipe connecting structure that this utility model builds, including the female pipe of need docking two 4, two female pipes 4 are connected by this utility model, and the two ends of described connecting tube 2 plug respectively In two female pipes 4, and the two ends of described connecting tube 2 are equipped with in the junction with female pipe 4 Sealing ring 3；

Big lasso 12 of the present utility model is set on female pipe 4, and female pipe 4 is provided with for fixed Second collar flange 41 of position, the length of the major axis of described big lasso 12 is ring-type convex more than second The external diameter of edge 41, the length of short axle is less than the external diameter of the second collar flange 41.

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.

Pipe joint 1 and connecting tube 2 connect the used of female pipe 4, and wherein pipe joint plays connection mother Pipe 4 and the effect of connecting tube 2；The little lasso 11 of pipe joint 1 is enclosed within connecting tube 2, greatly 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 After inserting in breach 111, little lasso 11 is fixed on described plush copper 22 and described first ring-type convex Between edge 21, the external diameter of connecting tube 2 is equal with the internal diameter of little lasso 11, but due to little lasso 11 have certain elasticity, and the existence of breach 111 so that it is empty that little lasso has certain deformation Between, it is simple to little lasso 11 is enclosed within described connecting tube 2.

After little lasso is fixed in connecting tube 2, connecting tube 2 is inserted in female pipe 4, press bullet Sheet 13, the major axis ((i.e. distance between AB)) of big lasso 12 diminishes, short axle (i.e. CD Between distance) become big, until the short axle of big lasso is more than the second collar flange on female pipe 4 41 external diameter time, big lasso 12 is through the second collar flange 41 and is enclosed within female pipe 4, stops Only pushing shrapnel 13, big lasso 13 restores to the original state, and minor axis length is less than the second collar flange 41 External diameter, the second collar flange 41 plays position-limiting action, and big lasso 13 will not be from female pipe 4 Slipping, two female pipes 4 are effectively connected by connector, and female pipe 4 leads to the junction of connecting tube 2 Cross sealing ring 3 to seal.

In like manner, dismantling big lasso 12 and during connecting tube 2, push shrapnel 13, when big lasso When the short axle of 12 is more than the external diameter of the second collar flange 41 on female pipe 4, big lasso 12 passes Second collar flange 41 is taken off from female pipe 4, now, extracts connecting tube 2 out.Dismounting When little lasso 11 and connecting tube 2, make breach 111 on little lasso 11 along plush copper 22 from Take off in connecting tube 2.

Content described in this specification embodiment is only the way of realization to utility model design Enumerate, protection domain of the present utility model is not construed as being only limitted to what embodiment was stated Concrete form, protection domain of the present utility model also includes that those skilled in the art are according to this practicality Novel design it is conceivable that equivalent technologies means.
