Abstract

A kind of pipeline unilateral side connection structure, including a pipeline, it is characterised in that：A mouth of pipe is opened up on the pipeline, it is more than the gasket of mouth of pipe maximum caliber in tap equipped with an outer diameter, an external clamp is inserted in mouth of pipe, the external clamp has an ontology for being through at tap and the pedestal positioned at body end and in pipeline, channel is equipped in ontology, the gasket is placed on ontology, and the outer diameter of pedestal is more than gasket internal diameter, further includes the lock-connecting piece that gasket can be made to be pressed in pipeline inner wall with body fits.

Description

A kind of pipeline unilateral side connection structure

Technical field

The utility model is related to field of pipeline connection, and in particular to arrive a kind of pipeline unilateral side connection structure.

Background technology

People's daily life or industrial equipment, product etc. often use piping connection, some pipe passages are frequent in reality An external pipeline is needed, and external pipeline is required to need to seal with former channel；But former pipeline is limited to material itself sometimes Or the conditions such as production technology, cost, complicated structure design or post-processing cannot be carried out, is also inconvenient to dismantle replacement, this is just urgently A kind of simple and reliable pipeline jointing construction, the utility model is needed thus to generate.

Utility model content

The scheme that the utility model is taken is：

A kind of pipeline jointing construction, including a pipeline, it is characterised in that：Mouth of pipe, branch pipe are offered on the pipeline It is more than the gasket of mouth of pipe any two points maximum distance in mouthful equipped with an outer diameter, an external clamp is inserted in mouth of pipe, it is described External clamp there is an ontology for being through at mouth of pipe and the pedestal positioned at body end and in the pipeline, be equipped in ontology Channel, the gasket are placed on ontology, and the outer diameter of pedestal be more than gasket internal diameter, further include can and body fits make it is close Packing is pressed in the lock-connecting piece of pipeline inner wall.

In the preferred embodiment of the utility model, the lock-connecting piece is nut, and the body outer wall is equipped with and spiral shell The external screw thread of female screw-internal thread fit.

In the preferred embodiment of the utility model, the nut bottom is from top to bottom equipped with the diminishing cone of outer diameter Shape portion, gasket is interior to be from top to bottom equipped with the diminishing bellmouth of internal diameter equipped with corresponding.

In the preferred embodiment of the utility model, the mouth of pipe cross-sectional shape includes round, ellipse or more Side shape.

In the preferred embodiment of the utility model, the mouth of pipe quantity is one or more than or equal to two.

Using the connection structure of the utility model, as long as drilling on former pipeline, you can complete branch connection.Without will be former Pipeline dismounting is replaced, and the branch pipe connection of the pipeline of existing inconvenient dismounting is especially suitable for.

Specific implementation mode

In order to which the utility model is explained further, it is described in detail below by specific embodiment.

Referring to Fig. 1 to Fig. 3, the utility model includes a former pipeline 1, which is rectangular, tool in the present embodiment There is a plane 1-1, through-hole 1-2 is opened up on plane 1-1.

The utility model further includes external clamp 2, gasket 4 and nut 3, and the external clamp 2 includes cylindrical Channel 2-3 is set inside ontology 2-1, ontology 2-1.The bottom of ontology 2-1 extends outward is equipped with pedestal 2-2, the pedestal 2-2 Diameter be less than or equal to through-hole 1-2 aperture.The outer diameter of the gasket 4 is more than the aperture of through-hole 1-2,4 sets of gasket It is connected on ontology 2-1.

The internal diameter of gasket 4 is the bellmouth 4-1 from top to bottom reduced in the present embodiment, the bottom of nut 3 by up to The diminishing tapered portion 3-1 of outer diameter is had, the tapered portion 3-1, which can be sealed, is inserted into bellmouth 4-1, convenient for sealing.

4 radial direction of gasket can be inwardly compressed before installation, and clamp 2 external in this way and gasket 4 can be logical across this Hole 1-2；Then locking nut 3, gasket 4 can tightly be attached to table in duct wall under 3 collective effect power of external clamp 2 and nut Face, and radial direction will not be toward inside contracting, gasket 4 and external clamp 2 can be fastened on former pipeline 1, thereby realize fastening With the effect of sealing.

Embodiment 2

It is essentially identical referring to Fig. 4 and embodiment 1, the difference is that in the present embodiment, former pipeline 1 is pipe.Due to The deformability of gasket can equally seal.

Embodiment 3

It is essentially identical referring to Fig. 5 and embodiment 1, the difference is that in the present embodiment, the hole 1-5 opened on former pipeline 1 For rectangle, the diameter of gasket is more than the diagonal line of rectangle.
