Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of connectors and relates to a connector. Background Art
[0002] The pipeline system is the most commonly used system for transporting liquid media and gaseous media. Connections are often required between pipelines to ensure the convenience of media transportation. A connector is also a detachable connection point between components and pipelines, playing an indispensable and important role in pipe fittings and being widely used in various places.
[0003] Currently, the common connection method between connectors and pipelines on the market is threaded connection, which has the advantage of good connection stability. However, when actually connecting the connector, to ensure connection stability, the connector or the pipeline needs to be rotated multiple times to increase the connection length. And to ensure the sealing performance after connection, it is often necessary to wrap sealing tape around the threaded section for sealing, making the connection operation relatively inconvenient. Summary of the Utility Model
[0004] The purpose of the present utility model is to address the above problems existing in the prior art and propose a connector, which solves the problem of relatively inconvenient connection operation between existing connectors and pipelines.
[0005] The purpose of the present utility model can be achieved by the following technical solutions:
[0006] A connector includes a tubular body and a cylindrical connecting sleeve. It is characterized in that one end of the connecting sleeve is sleeved outside the body and axially fixed to the body. An insertion port for inserting a pipeline is formed between the inner wall of the connecting sleeve and the outer wall of the body. A plurality of circular protruding sealing portions are provided on the outer side of the body at the insertion port, and the plurality of sealing portions are spaced along the axial direction of the body. The wall thickness of the connecting sleeve is less than the wall thickness of the end of the body, and the end of the body passes through the end of the other end of the connecting sleeve.
[0007] When connecting a pipeline with this connector, the end of the pipeline can be inserted into the insertion port between the connecting sleeve and the body. The body is relied on to support the inside of the pipeline, and the plurality of protruding sealing portions on the outer side of the pipeline are relied on to abut and seal the inner wall of the pipeline. Then, a pipe crimper presses the connecting sleeve with a smaller wall thickness tightly against the outer side of the pipeline to achieve the connection between the connector and the pipeline. Here, the pipe crimper is an existing pipeline connection device. During the connection process of this connector and the pipeline, only the steps of insertion and pressing by the pipe crimper are required. Compared with the threaded connection structure, the connection operation is more convenient.
[0008] In the above-mentioned joint, the outer side of the pipe body has an annular recessed mounting groove, and one end of the connecting sleeve away from the end of the pipe body is sleeved on the outer side of the pipe body at the position of the mounting groove, and a part of the side of the connecting sleeve is clamped into the mounting groove. During production, the pipe body and the connecting sleeve can be produced separately. The inner diameter of the connecting sleeve can be larger than the outer diameter of the pipe body. During assembly, the connecting sleeve is sleeved on the outer side of the pipe body, and the part of the connecting sleeve opposite to the mounting groove is compressed by an existing necking machine, so that the connecting sleeve shrinks and deforms at this part and is clamped into the mounting groove to realize the fixation of the connecting sleeve and the pipe body, and the operation is relatively convenient.
[0009] In the above-mentioned joint, the outer side of the pipe body has a protruding annular shoulder, and several of the above-mentioned sealing parts are located between the shoulder and the end of the pipe body. The end face of the shoulder facing the end of the pipe body is a plane, and the mounting groove is opened on the outer side face of the shoulder. The setting of the shoulder not only enhances the strength of the pipe body, facilitates the opening of the mounting groove, but also enables a socket to be directly formed between the inner wall of the connecting sleeve axially fixed on the shoulder and the outer side of the end of the pipe body without additional operation, which is relatively convenient. And the end face of the shoulder is a plane, which can be abutted by the end of the pipe inserted into the socket to realize the axial limit of the pipe.
[0010] In the above-mentioned joint, at least one of the several sealing parts has a tapered surface at one end facing the end of the pipe body, and the diameter of the tapered surface gradually decreases from the shoulder to the direction of the end of the pipe body. The setting of the tapered surface facilitates the insertion of the pipe.
[0011] Compared with the prior art, in the process of connecting this joint to the pipe, only the steps of plugging and crimping with a crimping machine are required. Compared with the threaded connection structure, the connection operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0016] Such as Figure 1As shown in the figure, this joint includes a tubular body 1 in the shape of a circular tube and two connecting sleeves 2 in the shape of a cylinder. The two connecting sleeves 2 are respectively sleeved on the outer sides of both ends of the body 1, and the end parts of both ends of the body 1 respectively pass through the two connecting sleeves 2. On both opposite sides of the middle part of the body 1, there are operating surfaces 8 that are flat, and the two operating surfaces 8 are parallel to each other.
[0017] Since the connection structures at both ends of the body 1 are the same, the structure of one of the ends will be taken as an example for description below.
[0018] As Figure 2 shown in the figure, the outer side of the body 1 has a convex shoulder 6 protruding in a circular ring shape. One end face of the convex shoulder 6 facing the end of the body 1 is flat. There are two mounting grooves 5 recessed in a circular ring shape on the outer side surface of the convex shoulder 6. The two mounting grooves 5 are spaced apart along the axial direction of the body 1. One end of the connecting sleeve 2 away from the end of the body 1 is sleeved on the outer side of the body 1 at the position of the mounting groove 5, and a part of the side of the connecting sleeve 2 is clamped into the mounting groove 5 to achieve axial fixation with the body 1.
[0019] An insertion opening 3 for inserting a pipeline is formed between the inner wall of the connecting sleeve 2 and the outer wall of the body 1. On the outer side of the body 1 at the insertion opening 3, there are several sealing parts 4 protruding in a circular ring shape, and the several sealing parts 4 are spaced apart along the axial direction of the body 1, that is, the several sealing parts 4 are all located between the convex shoulder 6 and the end of the body 1. In this embodiment, the connecting sleeve 2 is made of stainless steel material, and its wall thickness is small to facilitate deformation, especially smaller than the wall thickness of the end of the body 1. The body 1 can be made of plastic material; one of the several sealing parts 4 has a tapered surface 7 at one end facing the end of the body 1, and the diameter of the tapered surface 7 gradually decreases from the convex shoulder 6 towards the end of the body 1.
[0020] When this joint is produced, the body 1 and the connecting sleeve 2 are produced separately. The inner diameter of the connecting sleeve 2 is larger than the outer diameter of the convex shoulder 6 of the body 1. During assembly, the connecting sleeve 2 is sleeved on the outer side of the convex shoulder 6 of the body 1, and the position of the connecting sleeve 2 opposite to the mounting groove 5 is compressed by an existing necking machine, so that the connecting sleeve 2 shrinks and deforms at this place and is clamped into the mounting groove 5 to achieve the fixation of the connecting sleeve 2 and the body 1.
[0021] When connecting the pipeline, the end of the pipeline is inserted into the insertion opening 3 between the connecting sleeve 2 and the body 1. The body 1 is relied on to support the inside of the pipeline, and the several sealing parts 4 protruding from the outer side of the pipeline are relied on to abut and seal the inner wall of the pipeline. Then, an existing stainless steel crimping machine is used to tightly press the connecting sleeve 2 with a small wall thickness on the outer side of the pipeline to achieve the connection between the joint and the pipeline.
[0022] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but they will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
