The locking nut and the coupling nut are connected into a whole via inner and outer threads and locked together, and the rubber seal ring is positioned between the coupling nut and the joint. The utility model has the characteristics of definite elasticity (proper expansion and contraction) without the need of a spanner or a grip wrench during installation and a raw material band, and the utility model has the advantages of favorable sealing performance, easy use and maintenance and quick, convenient and reliable connection.
Description
Technical field the utility model belongs to the pipeline connection device, is specifically related to the architecture advances of pipeline connection with loose joint, is applicable to the connection between all kinds of water meters and valve, water meter and water pipe, valve and water pipe or the water pipe.
Background technique be when needing water meter or valve are installed in pipe-line system, or between water meter and the water pipe, between valve and the water pipe or when connecting between water pipe and the water pipe, the common practice is to adopt the loose joint of a standard type to realize.Commercially available traditional loose joint at present is made up of two coupling nuts, a locking nut, adopts this loose joint to connect, and is nonelastic, need be during installation by spanner or pipe tongs, non-leakage in order to guarantee the tieing place, all need on the interface outside thread, to twine the multilayer raw meal belt, make troubles to I﹠M.
The summary of the invention technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of and have certain elasticity (can suitably stretch), install not need by spanner or pipe tongs, need not adopt raw meal belt and have good seal performance, non-leakage, working service convenient, it is quick and easy to realize, the Elastic loose joint of connection reliably.
The technological scheme that its technical problem that solves the utility model adopts is: it comprises coupling nut, locking nut, joint, rubber gasket and snap ring, locking nut one end is by snap ring and joint inlet end link joint, the other end and coupling nut connect, utilize its internal and external threads to be coupled to integral body and locking between the two, rubber gasket is between coupling nut and joint.
As further improvement of the utility model, described coupling nut one end is provided with internal thread, and the other end is provided with outside thread, is provided with an externally threaded end and is provided with the rubber gasket mounting hole, its aperture＞internal thread aperture; Described locking nut is provided with internal thread and spacing draw-in groove; The inlet end of described joint is provided with limited step, and water outlet end is provided with the connection screw thread, and the inlet end end face is provided with the waterline groove, is provided with the semicircle groove on limited step; Described snap ring is provided with opening.
Compared with prior art, the beneficial effects of the utility model are:
1, because of being provided with rubber gasket between coupling nut and the joint, makes it flexible, promptly have certain extending amount, can between required connecting piece, regulate freely, with the size error of compensation connecting piece.
2, need only not twist with hand and can finish connection and reach reliable seal request by spanner or pipe tongs, working service is convenient.
3, when adopting at present commercially available traditional loose joint, non-leakage in order to guarantee the tieing place, all need on the interface outside thread, to twine the multilayer raw meal belt, this Elastic loose joint then need not adopt raw meal belt can reach the requirement of high sealing degree, and is easy for installation, quick, reliable.It is to rely on the rubber gasket that is arranged between coupling nut and the joint to seal, when the continuous precession of locking nut compresses, part two end faces relative with joint that are coupled that connect with coupling nut are pressed on two end faces of rubber gasket, thereby reach the requirement of sealing; In the design of the inlet end end face of joint " waterline groove " arranged, allowing some extruding allowance of rubber gasket after being squeezed be filled in wherein, thereby more can guarantee sealability.

Embodiment is described in detail the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, Elastic loose joint of the present utility model, comprise coupling nut 2, locking nut 3, joint 4, rubber gasket 5 and snap ring 6, locking nut 3 one ends are by snap ring 6 and joint 4 inlet end 4-4 link joints, the other end and coupling nut 2 connect, utilize its internal and external threads to be coupled to integral body and locking between the two, rubber gasket 5 is between coupling nut 2 and joint 4.
As shown in Figure 2, described coupling nut 2 one ends are provided with internal thread 2-1, be used for connecting (see figure 1) with required connecting piece 1, the other end is provided with the outside thread 2-2 that connects usefulness with locking nut 3, this end also is provided with the mounting hole 2-3 of rubber gasket 5, its aperture＞internal thread 2-1 aperture is for placing rubber gasket 5 usefulness; As shown in Figure 3, locking nut 3 is provided with the internal thread 3-1 that connects with coupling nut 2, also is provided with by the spacing spacing draw-in groove 3-2 of snap ring 6; As shown in Figure 4, be provided with limited step 4-3 with the inlet end 4-4 of the joint 4 of locking nut 3 link joints, water outlet end 4-5 is provided with the connection screw thread, this example is an outside thread, inlet end 4-4 end face is provided with waterline groove 4-1, its role is to allow rubber gasket 5 some extruding allowance after being squeezed be filled in wherein, thereby more can guarantee sealability, on limited step 4-3, be provided with and supply the fixedly semicircle groove 4-2 of snap ring 6 usefulness; As shown in Figure 5, snap ring 6 is provided with opening b.Coupling nut 2 and locking nut 3 can be steel, iron, copper, aluminium or other metallic material and make, and also can be nylon, engineering plastics or other nonmetallic material and make, and snap ring 6 can be Spring Steel Wire, stainless pot steel wire or ordinary steel wire and makes.
Installation process of the present utility model is: the internal thread 2-1 end precession that will have the coupling nut 2 of internal and external threads earlier is coupled the water outlet end 1-1 of part 1, locking nut 3 is inserted in joint 4 inlet end 4-4, again snap ring 6 is embedded in the semicircle groove 4-2 of joint 4, though this moment, locking nut 3 can be in joint 4 inlet end 4-4 move left and right, but because the restriction of snap ring 6 but can not pull joint 4 inlet end 4-4; Joint 4 is had the water outlet end 4-5 and the required connecting piece that connect screw thread to be connect; Rubber gasket 5 is put in the mounting hole 2-3 of rubber gasket 5 of coupling nut 2; At this moment, screw thread 3-1 within the locking nut 3 is aimed at screw thread 2-2 outside the coupling nut 2, enter to tighten with hand-screw, the limited step 4-3 at the inlet end 4-4 place of joint 4 is close to the end face of rubber gasket 5, because locking nut 3 precession constantly compresses, cause the water outlet end 1-1 that is coupled part 1 and the inlet end 4-4 of joint 4 to ride over two end faces of rubber gasket 5 tightly, thereby reach the requirement of sealing.Simultaneously, because of and coupled 1 of connecting of coupling nut 2 and joint 4 between be provided with rubber gasket 5, make to have certain extending amount between them, can between required connecting piece, regulate freely, to compensate the size error of connecting piece.In order to reach the non-leakage again purpose of sealing fully, in the design of the inlet end 4-4 of joint 4 end face " waterline groove 4-1 " arranged, allowing rubber gasket 5 some extruding allowance after being squeezed be filled in wherein, thereby more can guarantee sealability.
