Embodiment

Below in conjunction with accompanying drawing, device of the present utility model and using method are described in detail.For related all parts, to using its function of describing as the restriction of naming in specification, and be not subject to the restriction of the utility model concrete noun used, those skilled in the art also can select other noun to describe.

First the utility model term used is made an explanation:

1, Spielpassung: refer to the have gap cooperation of (comprising that minimum clearance equals zero), now the tolerance range in hole is on the tolerance range of axle; In the utility model, refer to that the external diameter of parts is less than or equal to the assembly relation of the internal diameter of outer sleeve 1;

2, interference fit: the cooperation with interference (comprising that minimum interference equals zero) is called interference fit, and now the tolerance range in hole is under the tolerance range of axle; In the utility model, refer to that the external diameter of parts is greater than the assembly relation of the internal diameter of outer sleeve 1;

3, transition fit: the cooperation may with gap or interference is called transition fit.

As shown in Figure 1 and Figure 2, pipe jointer of the present utility model, includes as the outer sleeve 1 of main body with for pipeline being installed to the press seal ring 2 in outer sleeve 1 inner chamber; The internal surface generation transition fit of the outer surface of described press seal ring 2 and outer sleeve 1 is provided with the locking ring 3 for preventing that pipeline from exiting in the direction of advance of press seal ring 2; And between press seal ring 2 and outer sleeve 1, retaining ring 4 is also installed.And, be terrible better sealing effect, pad 5 is also installed between press seal ring 2 and locking ring 3 and is no less than the Sealing 6 (Fig. 3) of.

The direction entering by pipeline as the outer sleeve 1 of main body can be divided into 111He connection area, lock sealing district 112 (Fig. 4), wherein in lock sealing district 111 for placing retaining ring 4, press seal ring 2 and locking ring 3; Therefore, its internal diameter is greater than the internal diameter of connection area 112.And, in connection area, 112 medium positions preferably have the region that internal diameter is less than the pipeline that will connect, thereby make pipeline there is a terminating point advancing, with time can have enough active forces to guarantee that press seal ring 2, locking ring 3 and retaining ring 4, with the outer surface of pipeline and the internal surface of outer sleeve 1, possible interference fit occurs.

Can outer sleeve 1 can be double-way pipe or threeway, four-way pipe, for easy-to-operat, has one and put forth effort hole 7 on the outer surface of outer sleeve 1, facilitate external force that press seal ring 2 is pressed in outer sleeve 1.

And the effect of press seal ring 2 is pipeline to be pressed in outer sleeve 1, and can play seal action.In use, the internal diameter of press seal ring 2 selects to guarantee the outer surface generation Spielpassung with pipeline 1.And, when advancing along pipeline, under the internal surface active force of outer sleeve 1, preferably occurred to melt with pipeline 1 and coordinated.On the outer surface of press seal ring 2, be useful on the first non-return boss 21 corresponding with straight-tooth 41, the helical teeth 42 of retaining ring 4 and the second non-return boss 22 (Fig. 5); At the straight-tooth 41 of retaining ring 4, under the obstruction of helical teeth 42, the first non-return boss 21 and the second non-return boss 22 can prevent that press seal ring 2 from exiting from outer sleeve 1.Before using, retaining ring 4 and locking ring 3 are all arranged in outer sleeve 1, and straight-tooth 41 and the helical teeth 42 of retaining ring 4 are positioned at the first non-return boss 21 simultaneously, thereby stop press seal ring 2 to exit outer sleeve 1.Such structure just parts integration together, has been avoided the problem of assembling.And preferably the external diameter of the second non-return boss 22 is greater than the internal diameter of helical teeth 42 formed annulars; So only, under nonlocal effect, press seal ring 2 could move forward.

Wherein retaining ring 4 can be arranged in outer sleeve 1 by the mounting groove of opening at outer sleeve 1 internal surface, on its circumference, intersects and is distributed with straight-tooth 41 and helical teeth 42; Wherein the angle of helical teeth 42 and straight-tooth 41 can be 5-10 degree (Fig. 6).When assembled state, the straight-tooth 41 of the connection area 112 of sleeve pipe 1 self can prevent that press seal ring 2 from exiting from outer sleeve 1 outward; And in assembling, due to outside active force, press seal ring 2 is moved by 111Xiang connection area, lock sealing district 112, and the external diameter of the second non-return boss 22 is greater than the internal diameter of helical teeth 42 formed annulars, like this when the second non-return boss 22 passes through after helical teeth 42 with interference fit, helical teeth 42 just falls in the groove of the first non-return boss 21 and the second non-return boss 22 formation, thereby makes press seal ring 2 be difficult to exit in the other direction again.And under the active force of helical teeth 42, press seal ring 2 can be transitioned into interference fit by Spielpassung with pipeline, thereby reaches sealing fastening effect.

And, in the place ahead of retaining ring 4 (direction that move 111Xiang connection area, Ji Cong lock sealing district 112), locking ring 3 is installed, described locking ring 3 is transition fit at the outer surface in when assembling and the internal surface of outer sleeve 1, and the internal diameter of the internal surface that locking ring 3 is formed by fixing tooth 31 is less than or equal to the external diameter of wanted pipe laying, its internal diameter can diminish (figure) under external force time due to the formed internal surface of fixing tooth 31, under external force, can on pipeline, there is interference fit in its fixing tooth 31, thereby pipeline can not be exited from outer sleeve 1, play the effect of locking.

In order better to open the effect of sealing, pad 5 is also installed between press seal ring 2 and locking ring 3 and is no less than the Sealing 6 of; Described Sealing 6 is rubber ring.The external diameter of rubber ring selects to be more than or equal to the internal diameter of outer sleeve 1, and under the promotion of press seal ring 2, rubber ring is pressed against each other, and the space between closed conduct outer sleeve in August 1.

When using pipe jointer of the present utility model, the pipeline that will connect is through press seal ring 2, pad 5, the rear arrival locking ring 3 of Sealing 6, if the internal diameter on the fixing tooth 31 formed surfaces of locking ring 3 is greater than the external diameter of pipeline, pipeline is also through locking ring 3, until be positioned at the joint 112 of outer sleeve 1.Then, under external force, press seal ring 2 travels forward, and compress gasket 5 and Sealing 6 also promote locking ring 3 and travel forward.When locking ring 3 travels forward, its fixing tooth 31 surperficial internal diameter that forms diminishes gradually, is finally clamped on pipeline.

And when the internal diameter on the fixing tooth 31 formed surfaces of locking ring 3 is less than the external diameter of pipeline, under external force, pipeline can pass fixing tooth 31, finally makes firmly locking pipe of locking ring 3.

Size for the utility model all parts is not done concrete restriction, and those skilled in the art can as required, adjust under technical thought of the present utility model.
