Abstract

A press seal type thin wall pipe joint piece consists of a connection pipe[1], a joint [2], a screw cap[3], an o-ring seal [4], a retainer ring [5], wherein the connection end of the connection pipe[1] is provided with a protruding clip[6]; the joint is provided with a narrow opening; the screw cap[3], the o-ring seal [4] and the retainer ring [5] are sleeved on the connection tube; the screw cap[3] is matched with the male thread [7]of the joint to play the role of positioning and sealing. The utility model has a simple structure and a reasonable design, and solves the problem of hard connection of thin wall pipes and improves pipe flux and transmission efficiency; besides, the site operation is simple and the connection is firm with good sealing performance, thereby being easy to be popularized and applied.

Description

The press seal type thin wall pipe connector

The utility model relates to a kind of pipe and connects black box, and particularly a kind of press seal type that is applied in the thin walled tube connection connects Sealing.

In the prior art, pipe is widely applied at industry and in life, the connection tap water that is mainly used in life, tradition is used galvanized pipe, now uses aluminium-plastic composite pipe again, and its tube wall is thicker, adopt hinge silk screw thread to be connected with pipe fitting, sealability is better, and site operation is easy.But because its tube wall is thicker, latus rectum is less in the pipe, and discharge value is also less, particularly use a period of time after, the incrustation of water is many, more influences water flow, even influence uses, its outward appearance is attractive in appearance inadequately.Patent 00225509.x, 00245795.4 also provides new pipe connector, but is unsuitable for using on the light wall pipe.

The utility model is applied to pipeline transmission to thin walled tube for the shortcoming that overcomes above-mentioned prior art provides a kind of improved press seal type thin walled tube link, improves pipe quantity delivered and aesthetic property, and its good airproof performance is practical.

The purpose of this utility model can realize by following technical measures: this fitting is made up of joint, nut, O-ring seal, ring washer, adapter, and the connecting end of adapter is provided with convex clip, and convex clip is formed by instrument expansion tube wall, is the convex parts of tube wall.Joint is provided with slot, the internal diameter of slot is more bigger than the external diameter of taking over, adapter convex clip in joint is pressed by the slot card, joint is taken over the nut of holding on being provided with outside thread and being sleeved on adapter and is cooperated, the nut the other end is the slot end, the internal diameter of nut slot end is more bigger than the external diameter of taking over, can be along tube activity, be provided with ring washer between the convex clip of adapter and the nut slot end and O-ring seal is sleeved in the adapter.Take over convex clip and withstand the joint slot, nut cooperates with joint, and the slot end compressing O-ring seal location and the sealing of nut realize that pipe connects.Adopt this structure and Placement, can make pipe joints such as straight joint, elbow, threeway, four-way, be applied in the connection of pipe.

Concrete structure of the present utility model and embodiment are provided by the following drawings:

Fig. 1 is the structural drawing of press seal type thin wall pipe connector;

Fig. 2 is the structural drawing of embodiment's threeway fitting;

Fig. 3 is the structural drawing of embodiment's elbow fitting;

The utility model is described in further detail below with reference to accompanying drawing: with reference to figure; The common thickness of light-wall pipe is 0.6～1.2mm; Make protrusion at the on-the-spot tool using docking of adapter pipe end; Protrusion can be a plurality of protruding points; Boss or bulge loop; The i.e. convex clip [6] of the light-wall pipe among the figure [1]; Joint [2] is taken over end and is larger caliber; External screw thread [7] is arranged; Joint is taken over end and has been right after slot, and the slot internal diameter is more bigger than taking over external diameter, and adapter can be inserted in the slot; The outstanding adapter external diameter of convex clip [6]; Convex clip roof pressure slot location, nut [3] is sleeved in the adapter, and the internal thread of nut [8] cooperates with joint external screw thread [7]; Nut [3] other end is the slot end; Slot end internal diameter can be along tube activity than taking over the big 0.5～2mm of external diameter, and ring washer [5] is arranged between the convex clip of adapter [6] and the nut slot end; O-ring seal [4] is sleeved in the adapter; Ring washer [5] withstands convex clip [6]; O-ring seal [4] withstands the slot end of ring washer [5] and nut, and O-ring seal is elastomer, can be artificial or natural rubber etc. Take over that convex clip [6] is preceding to have slot to withstand, after have ring washer [4], O-ring seal to oppress by nut, play location, seal action.This assembly saves ring washer and also can use, and effect has the ring washer ideal inadequately.This component application connects at thin walled tube, is particularly suitable for using stainless-steel thin-wall pipe, according to the site operation needs, pack into nut, O-ring seal, ring washer after, become convex clip with instrument taking over the end dilatating and deformable, can take over.Can be made into other with this Connecting format, structure and be used for the pipe joint that pipe connects, see Fig. 2, Fig. 3 as threeway, elbow.

Of the present utility model simple in structure, reasonable in design, overcome thin walled tube and use to have connected the big problem of difficulty, improve the discharge value and the efficiency of transmission of taking over, site operation is easy, connect firm, good airproof performance, promotion and implementation are easy.

Claims

1. press seal type thin wall pipe connector, adapter [1], joint [2] are arranged, it is characterized in that the connecting end of taking over [1] is provided with convex clip [6], joint [2] is provided with slot, the convex clip [6] of the slot top clamping pipe of joint [2], joint [2] is taken over the nut [3] of end on being provided with outside thread [7] and being sleeved on adapter and is cooperated, and the nut the other end is the slot end, is provided with ring washer [5] between convex clip of adapter [6] and nut [3] the slot end, O-ring seal [4] is sleeved in the adapter.
