Abstract

The utility model provides a frustum quick connector for plastic pipelines, which applies a frustum stepped plastic pipe joint and a V-shaped sealing ring, wherein the V-shaped sealing ring inlaid in the annular groove inside the interface of the joint pipe fitting is connected in a tight manner with the inserted pipe joint, and cooperates with the precession type clamp sleeve that is socketed on the root part of the frustum stepped pipe of the pipe joint within the clamp spiral groove in the edge of the pipe fitting interface to couple the pipe joint and the pipe fitting in a fastened manner. Being innovatively structured, of fast coupling effect, and convenient to use, the utility model can be applied for mated coupling of various plastic tubular products and pipe fittings, and is a new type of quick connector for plastic pipelines.

Description

Plastic pipe frustum formula quick connector

The utility model relates to a kind of pipeline connecting device, specifically a kind of joiner of plastic pipe.

Existing plastic pipe joiner especially plastic tube connects with mainly adopting scyewed joint, flange connection, enlarging blistering connecting of joint pipe fitting.But it is loaded down with trivial details that it exists installation and processing, time-consuming, and joint strength is low, use is inconvenient.Along with the development of plastics industry, need constantly to develop novel plastic pipe joiner.

The purpose of this utility model provides equipped simple and easy quick, time saving and energy saving, the novel plastic pipeline joiner that joint strength is high, easy to use of a kind of novel structure, processing.

The utility model realizes that the technical solution of above-mentioned purpose is: frustum stepwise pipe joint is made in the end connector design of plastic pipe, being shaped on ring groove setting-in v-ring in the interface of joint pipe fitting is connected with pipe seal, and the interface of pipe fitting along on be shaped on and compress the spin slot screw type clamping sleeve that is placed on the root body of pipe joint frustum rank that is connected and connect the plastic pipe frustum formula quick connector that consists of with joint for plastic tube and pipe fitting are fastening.During use, earlier an end connector of plastic tube is made band tapering step type pipe joint, insertion tube joint after the ring groove of the pipe fitting interface of required connection is embedded in v-ring is compressed into and is screwed clamping sleeve, just realizes connecting of plastic tube and pipe fitting.

Because technique scheme has been adopted in the utility model design, consist of the frustum pipe joint and insert the quick plastic pipe coupler of skewer cooperating structure, it has novel structure than prior art, reasonable in design, process simple and easy, connect fast, the time and labour saving, advantage such as easy to use, especially frustum formula pipe joint makes the mouth of pipe that joins form the hoop reinforcement circle of a thickening, increased the intensity of interface, be connected with the self-pressure-sealed formula seal ring of V-arrangement again, connecting pipe joint tapering ramp effect, make pipe fluid pressure big more, its sealability is strong more, and it is stressed even, enlarged the application area of plastic tube, be applicable to PVC, PE, various plastic tubes such as PP and plastic pipe and cast iron, the supporting connection of metal pipe elements such as aluminum alloy, can be widely used in agricultural water-saving irrigation, ejectment water conservancy project journey, urban construction water supply project and oil, chemical industry, the connection engineering of industry pipelines such as mining is a kind of novel plastic pipe quick connector.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the sectional view of the utility model embodiment concrete structure.

Fig. 2 is the enlarged view of frustum stepwise pipe joint 1 among Fig. 1.

Fig. 3 be Figure 1A-A to cutaway view Amplified image.

Mark among the figure: 1, joint for plastic tube; 2, precession clamping sleeve; 3, v-ring; 4, pipe fitting.

Embodiment as shown in Figure 1, what this plastic pipe joiner adopted is frustum stepwise pipe joint 1 (seeing accompanying drawing 2 again), v-ring 3, be shaped on ring groove setting-in v-ring 3 in the interface of joint pipe fitting 4 and form with the pipe joint 1 of the company of inserting and be tightly connected, and be shaped on along portion at the interface of pipe fitting 4 and compress spin slot and be connected and be set in screw type clamping sleeve 2 (seeing accompanying drawing 3 again) on the pipe joint 1 frustum rank root body pipe joint 1 and 4 fastening connections of pipe fitting.

The tapering of frustum stepwise pipe joint 1 conehead is 1: 30～1: 50 in the utility model.

The pipe fitting 4 of connection that the utility model is joined is pipe fittings such as threeways various plastic materials or metal materials such as aluminum alloy, cast iron, elbow, reducer union.

Claims (2)

1, a kind of plastic pipe frustum formula quick connector, it comprises joint for plastic tube, seal ring, pipe fitting, it is characterized in that also comprising screw type clamping sleeve (2), joint for plastic tube is a frustum stepwise pipe joint (1), seal ring is v-ring (3), setting-in v-ring (3) is tightly connected with the pipe joint (1) of the company of inserting in the ring groove in joint pipe fitting (4) interface, and is connected in the spin slot compressing of pipe fitting (4) interface edge and is placed in screw type clamping sleeve (2) on the root body of pipe joint (1) frustum rank with pipe joint (1) and fastening connection of pipe fitting (4).

2, plastic pipe joiner according to claim 1 is characterized in that the tapering of frustum stepwise pipe joint (1) conehead is 1: 30～1: 50.
