Abstract
The utility model provides a coupling for pipe connection, the coupling is including having elastic little lasso and big lasso, little lasso is the ring form, big lasso is oval cyclic annularly, little lasso and the big coaxial setting of lasso, just the both ends that shell fragment and the major axis of big lasso are passed through to the both sides of little lasso link to each other respectively. Utilize the utility model discloses carry out the pipe connection, the installation is dismantled conveniently, need not to use any instrument, and the operator utilizes both hands can accomplish the installation and dismantles, and ability ascension pipe installs, dismantles and the efficiency of maintenance, need not to adjust the length of hose insertion hard tube, need not the chucking position of fitting card hoop, convenient and fast.
Description
Technical field
This utility model relates to a kind of pipe joint connected for pipeline.
Background technology
Along with the development of science and technology, the application of pipe-line system is more and more wider.Existing pipeline connecting mode is generally clamping hoop type connection, bite type connection, bayonet joint and welding type and connects.Installing space and tube wall thickness be there are certain requirements by bite type connection；Bayonet joint need to be pre-machined molding connecting pipe end；Welding type pipeline produces residual stress, and the tubing flexible compensation performance producing variations in temperature is low；If it is not in place that clamping hoop type connects clip, easily occur revealing, and when installation site and peripheral component produce and interfere, although rotating clip can meet installation requirement, but installation site is narrow sudden, dismounting clip is it is necessary that with specific purpose tool, therefore all there is the shortcoming that installing/dismounting is constant and wastes time and energy in above several pipelines connection.
Summary of the invention
For solving the problems referred to above, the utility model proposes a kind of pipe joint connected for pipeline.
The technical solution adopted in the utility model is:
A kind of pipe joint connected for pipeline, described pipe joint includes elastic little lasso and big lasso, described little lasso is circular, described big lasso is ring-type in ellipse, 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 with the major axis of big lasso.
The beneficial effects of the utility model are:
1, utilizing this utility model to carry out pipeline connection, 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
Referring to the drawings, a kind of pipe joint connected for pipeline, 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 ring-type in ellipse, little lasso 11 and big lasso 12 are coaxially disposed, and described little lasso 12 is respectively connected with by the two ends of shell fragment 13 with the major axis of big lasso 12；
Utilizing the pipe connecting structure that this utility model builds, including two female pipes 4 of needs 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；
Little lasso 11 is set in connecting tube 2 and is fixed by fixing device, described fixing device includes the circle plush copper 22 in the circle axial gap 111 on little lasso 11 inner face and connecting tube 2, in described plush copper 22 inserts described breach 111 and being pushed against on the first collar flange 21 outer face of little lasso 11, described first collar flange 21 is arranged in described connecting tube 2；
Big lasso 12 is set on female pipe 4, and female pipe 4 is provided with the second collar flange 41 for location, and the length of the major axis of described big lasso 12 is more than the external diameter of the second collar flange 41, and 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 1 plays the female pipe 4 of connection and the effect of 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, after plush copper 22 is inserted in breach 111, little lasso 11 is fixed between described plush copper 22 and described first 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, 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, during until the short axle of big lasso is more than the external diameter of the second collar flange 41 on female pipe 4, big lasso 12 is through the second collar flange 41 and is enclosed within female pipe 4, stop pushing shrapnel 13, big lasso 13 restores to the original state, minor axis length is less than the external diameter of the second collar flange 41, second collar flange 41 plays position-limiting action, big lasso 13 will not slip from female pipe 4, two female pipes 4 are effectively connected by connector, female pipe 4 is sealed by sealing ring 3 with the junction of connecting tube 2.
In like manner, dismantling big lasso 12 and during connecting tube 2, pushing shrapnel 13, when the short axle of big lasso 12 is more than the external diameter of the second collar flange 41 on female pipe 4, big lasso 12 is taken off from female pipe 4 through the second collar flange 41, 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 from 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.
