Abstract

The utility model relates to an extruding pipe joint, comprising a sealing ring and a pipe joint. At least one strip of groove is arranged on the inner wall of the pipe joint in the circumferential direction of the end surface of the inner circle of the pipe joint. The place where the groove is opened on the inner wall keeps a certain distance with the end surface of the circle of the pipe joint. The sealing ring is inserted in the groove. After pipes which need to be connected together are inserted into the pipe joint 4, the sealing and fixing effect can be achieved by extruding corresponding place outside the pipe joint. The utility model has the advantages of simple structure and convenient construction.

Description

The extruding type pipe joint

The utility model relates to a kind of pipe joint, particularly a kind of extruding type pipe joint.

Chinese patent application 91211181.x discloses a kind of " fast-connection pipeline ", it utilizes being threaded of external member of two band tapered indentations of the outer socket of pipe fitting, the seal ring that places two external member tapered indentations places compressed reach sealing, though this Placement connects a pipe fitting and only needs two external members, but screw thread, tapered indentations are arranged, the manufacturing process complexity on the external member.

The purpose of this utility model is to provide a kind of pipe joint with connection pipe fitting simple in structure, easy for installation.

For achieving the above object, the utility model is by the following technical solutions:

A kind of extruding type pipe joint comprises seal ring and pipe joint, and described pipe joint is opened at least one groove apart from the inwall of its nose circle face a distance along the circumferencial direction of interior circle, and described seal ring embedding is contained in the groove.Behind the pipe fitting insertion tube joint that will need during installation to connect, make seal ring about equally apart from the distance of the distance of the nose circle face of insertion end pipe joint and the nose circle face of distance pipe fitting insertion end, utilize crush inhury outside pipe joint, the seal ring position to be pushed again, make joint sealing; The position of the corresponding connection pipe fitting in butt joint exterior seal ring both sides is pushed simultaneously, and joint and connection pipe fitting are fixed.

The Connecting format that the utility model can be designed to use always, as have only pipe joint, tee union of pipe joint, the two ends reducing of the pipe joint of a connecting end, two connecting ends etc.

The size that the also visual pipe fitting of the utility model bears pressure increases the number of connecting end seal ring, the number at extruding position, seal ring two ends.

The utility model is simple in structure, when installing as long as corresponding site is pushed, easy to operate, can save cost, raise the efficiency.

The utility model will be further described below in conjunction with accompanying drawing and embodiment:

Fig. 1 is the utility model embodiment 1 a structural representation;

Fig. 2 is the utility model embodiment 2 a structural representation;

Fig. 3 is the utility model embodiment 3 a structural representation;

Fig. 4 is the utility model embodiment 4 a structural representation;

Fig. 5 is the utility model embodiment 5 a structural representation;

Fig. 6 is the schematic appearance that the utility model embodiment 1 connects.

With reference to accompanying drawing, number in the figure and parts are: the pincers splenium position 11,12,13 in connection pipe fitting 1,2,6, seal ring 3, pipe joint 4, heavy caliber end 5, the pipe joint outside.

Embodiment 1:

With reference to accompanying drawing 1,6, pipe joint connects two pipe fittings 1,6 in the present embodiment, and the inwall in distance pipe joint two nose circle face a distance respectively has a groove along the inner circumference direction, and described seal ring 3 embeddings are contained in the groove.Behind pipe fitting 1, the 2 insertion tube joints 4 that connect, make seal ring 3 about equally, utilize crush inhury outside pipe joint, pressure to be clamped at seal ring position 12 again, make joint sealing apart from the distance of the distance of the nose circle face of insertion end pipe joint and the nose circle face of distance pipe fitting insertion end; Pressure is clamped at the position 11,13 of the corresponding connection pipe fitting in butt joint exterior seal ring both sides simultaneously, and pipe joint 4 is fixing with connection pipe fitting 1,2.

Embodiment 2:

With reference to accompanying drawing 2, present embodiment is used for the occasion of bigger pressure as different from Example 1, and seal ring 3 numbers of each connecting end are increased to two.

Embodiment 3:

With reference to accompanying drawing 3, present embodiment is used for crooked occasion as different from Example 1, and pipe joint is a crooked joint.

Embodiment 4:

With reference to accompanying drawing 4, present embodiment is the reduction nipple of a single-ended connection.

Embodiment 5:

With reference to accompanying drawing 5, present embodiment is a tee union.

As seen the utility model can be designed to be applicable to the multi-form pipe joint of various connection occasions, and pipe joint structure is simple, easy for installation, and is with low cost.

Claims

1, a kind of extruding type pipe joint comprises seal ring and pipe joint, it is characterized in that described pipe joint opens at least one groove apart from the inwall of its nose circle face a distance along the circumferencial direction of interior circle, and described seal ring embedding is contained in the groove.
