Description

Extrusion type joint

Technical field

Pipe connecting element is the utility model is related to, more particularly to a kind of extrusion type joint.

Background technology

The non-metallic pipes such as plastic flexible pipe and rubber hose with pipeline during connecting, typically with iron wire by hose Tie tight on tube head, some slightly hard hoses need the head heating mantle by hose to use pipe collar on the tube head processed Tighten, there are the problem of be：With iron wire by flexible pipe fastening on tube head it is insecure, operation of the Hose Jacket on tube head is compared It is difficult.

The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the utility model, and It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form Technology.

Utility model content

The purpose of this utility model is to provide a kind of extrusion type joint, so as to overcome flexible pipe fastening with iron wire in tube head It is upper insecure, Hose Jacket is being operated into the problem of more difficult on tube head.

To achieve the above object, the utility model provides a kind of extrusion type joint, hose is connected to pipeline On tube head, extrusion type joint includes：Pipe collar and tap-type connector.Pipe collar has conical through-hole, and conical through-hole includes：It is small Mouth, big mouth and step.Osculum is opened in one end of pipe collar；Big mouth is opened in the other end of pipe collar；Step is opened in the interior of pipe collar Portion and one end of close big mouth, and step is spacing to be carried out to hose.Tap-type connector is in T font structures, and tap-type connects Head includes：Threaded portion and joint connection.One end of joint connection one end and threaded portion is affixed, and joint connection is another Hold to be connected with tube head.Wherein, hose enters from the osculum of pipe collar and is inserted into step, and the threaded portion of tap-type connector is from pipe The big mouth of hoop enters and is threaded into hose.

Preferably, in above-mentioned technical proposal, groove is offered on the outer circumference surface of threaded portion.

Compared with prior art, the utility model has the advantages that：The extrusion type joint of the utility model, has It is easy to operate, be connected firmly and the characteristics of good airproof performance.

Embodiment

Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality New protection domain and from the limitation of embodiment.

Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members Part or other parts.

As shown in Figure 1 to Figure 3, according to a kind of extrusion type joint of the utility model embodiment, to by hose 1 It is connected on the tube head of pipeline, extrusion type joint includes：Pipe collar 2 and tap-type connector 3.Pipe collar 2 has conical through-hole 5, and Conical through-hole 5 includes：Osculum, big mouth and step 6.Osculum is opened in one end of pipe collar 2；Big mouth is opened in the other end of pipe collar 2； Step 6 is opened in the inside of pipe collar 2 and close to one end of big mouth, and step 6 is spacing to be carried out to hose 1.Tap-type connector 3 In T font structures, and tap-type connector 3 includes：Threaded portion and joint connection 7.7 one end of joint connection and the one of threaded portion Hold affixed, and the other end of joint connection 7 with tube head being connected.Wherein, the osculum of hose 1 from pipe collar 2 enters and is inserted into To step 6, the threaded portion of tap-type connector 3 enters from the big mouth of pipe collar 2 and is threaded into hose 1.

Preferably, groove 4 is offered on the outer circumference surface of threaded portion.

In practical applications, extrusion type joint is made of pipe collar 2 and tap-type connector 3, is sleeved on the pipe collar on 1 head of hose 2 be small inner big 5 structure of conical through-hole of mouth, and hose 1 is inserted at pipe collar 2 to step 6, with the threaded portion of tap-type connector 3 from The internal diameter of hose 1 is screwed into, it is possible to 1 internal diameter of hose is cut partial threads, and 1 crimp of hose is filled in pipe collar 2 Conical through-hole 5 and tap-type connector 3 threaded portion between, by hose 1 be firmly fixed on pipe collar 2 and tap-type connector 3 it Between, the inner circle of pipe collar 2 is manufactured into the small inner big conical through-hole 5 of mouth, and in the large aperture side of conical through-hole 5 (the one of i.e. big mouth End) step 6 is provided with, the threaded portion of tap-type connector 3 is arranged to canalis spinalis thread shape, and equal in the outer circumference surface of canalis spinalis screw thread It is even to be machined with the groove 4 that form screw chasing sword.

In short, the extrusion type joint of the utility model, the process that tap-type connector is screwed into from hose head internal diameter, are exactly screw tap The process that hose is compressed and sealed by formula connector and pipe collar relative motion, has easy to operate, is connected firmly and good airproof performance Feature.
