Abstract

The utility model relates to a telescopic screwed pipe connector, which is characterized in that the pipe connector is composed of an outer sleeve pipe (1) and a telescopic connector (3) sheathed in the outer sleeve pipe (1); the middle part of the junction surfaces of the outer sleeve pipe and the telescopic connector is provided with a sealing component (2); the pipe connector is connected with a pipe passage through the outer screw threads arranged on one end and the inner screw threads arranged on the other end. As the pipe connector of the utility model is a telescopic pipe connector in the axial direction, so the deficiency of the prior art can be overcome effectively, which provides convenience for the maintenance and component changing of the water supplying pipe passage of a unit building.

Description

The thread type connection pipe fitting that stretches

The utility model relates to the connection pipe fitting between the water main pipe and main pipe and user's subtube on a kind of unit building, relates to the flexible connection pipe fitting of a kind of thread type specifically.

Of the prior art go up all adopts the locking clip ways of connecting to connect being connected between water main pipe and main pipe and the user's subtube, promptly fixed connection.When some parts damages (as valve) in the pipeline need to be changed, because of the pipeline at valve two ends does not have axial displacement, connect locking clip was again that plug-in type connects in addition, and this has just brought many inconvenience to the replacing of valve.

The purpose of this utility model provides a kind of rational in infrastructure with regard to being to overcome above-mentioned deficiency of the prior art, the adjustable thread type of the axial clearance connection pipe fitting that stretches.

The purpose of this utility model can adopt following measure to realize:

The flexible connection pipe fitting of thread type of the present utility model is made up of outer sleeve and the slip joint that is set in the outer sleeve; Between the junction plane of outer sleeve and slip joint, be provided with Sealing; Connection pipe fitting by being arranged on the one end outside thread and the internal thread of the other end be connected with pipeline.

Outer sleeve combines with slip joint and is processed with the seal groove that twice are installed seal ring on the inwall of end in the utility model, and its other end is processed with the internal thread that is connected with pipeline; The rear end of slip joint is processed with the outside thread that is connected with pipeline.

The utility model also can adopt outer sleeve to combine with slip joint and hold installation one annular end cap, and the mode of structure that seal ring and pressure ring are installed in end cap and the common inner groove that constitutes of outer sleeve is realized.

The utility model yet can adopt following scheme to realize: promptly, outer sleeve is formed by main sleeve pipe with by the coupled pipe joint of annular end cap, and main sleeve pipe combines with slip joint and is processed with the seal groove that twice are installed seal ring on the inwall of end.

Because connection pipe fitting of the present utility model is axial extension type connection pipe fitting, it has overcome deficiency of the prior art effectively, for the maintenance of unit building water supply pipeline, change parts convenience is provided.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the plan view of the utility model structure

Fig. 2 is the plan view of second kind of embodiment of the utility model.

Fig. 3 is the plan view of the third embodiment of the utility model.

The utility model is done with detailed description below with reference to embodiment's (accompanying drawing):

As shown in Figure 1, the flexible connection pipe fitting of thread type of the present utility model is made up of outer sleeve (1) and the slip joint (3) that is set in the outer sleeve; Outer sleeve combines with slip joint and is processed with the seal groove that twice are installed seal rings (2) on the inwall of end, and its other end is processed with the internal thread that is connected with pipeline; The rear end of slip joint is processed with the outside thread that is connected with pipeline.

As shown in Figure 2, outer sleeve in the utility model (1) combines with slip joint (3) to hold an annular end cap (4) is installed, in the common inner groove that constitutes of end cap (4) and outer sleeve (1), seal ring (2) and pressure ring (5) are installed, are processed with the internal thread that is connected with pipeline on the outer sleeve; The rear end of slip joint is processed with the outside thread that is connected with pipeline.

As shown in Figure 3, outer sleeve in the utility model (1) is formed by main sleeve pipe (6) with by the coupled pipe joint (8) of annular end cap (7), and main sleeve pipe (6) combines with slip joint (3) and is processed with the seal groove that twice are installed seal rings (2) on the inwall of end.
