Description

A kind of joint for plastic tube device

Technical field

Pipe fitting connection area is the utility model is related to, more particularly, to a kind of joint for plastic tube device.

Background technology

At present, in the market mainly realizes matching somebody with somebody between two joint for plastic tubes by the structure of clip or clamp spring Close.In this two kinds of coordinated schemes, except pipe fitting in itself in addition to, be required for extra accessory i.e. clip or clamp spring to realize. And both components result in the increase of pipe fitting cost.

Utility model content

The purpose of this utility model be exactly in order to overcome the problems of the above-mentioned prior art and provide it is a kind of it is easy to use, The joint for plastic tube device that cost is low, use scope is wide, detachability is good, design matching is good.

The purpose of this utility model can be achieved through the following technical solutions：

A kind of joint for plastic tube device, for the mutual cooperation connection of two pipe fittings, which includes being arranged on the first pipe The number of notch on connector and the boss structure being arranged on the second pipe fitting, the notch and boss structure Amount, location and shape cooperate, and pass through the rotating mode clamping of grafting.

The notch is circumferentially evenly distributed in the first pipeline main body of the first pipe fitting, the boss knot Structure is circumferentially evenly distributed in the second pipeline main body of the second pipe fitting.

The notch includes a L-shaped card slot and one and the first integrally formed groove shell of pipeline main body, institute The L-shaped card slot stated includes interconnected groove and hollow slots, and the connectivity part of the groove and hollow slots is equipped with a buckle, institute The groove shell stated is arranged on groove, and radially protrudes, and the groove shell is connected groove and hollow slots Place opens up a square hole.

The boss structure includes being arranged in the second pipeline main body and position multiple boss corresponding with L-shaped card slot.

The width of the boss is less than the width of groove, and the height of boss is less than the radial direction inner height of groove shell.

The width of the boss is less than the distance for being snapped into hollow slots one side wall, and the height of boss exists more than hollow slots Width at buckle.

The device further includes a ring type seal, which is installed on the seal groove of the second pipeline main body.

The buckle is a protrusion with arcing outer edges.

First pipe fitting and the second pipe fitting are metal tube or plastic tube.

The notch is equipped with 4-8 with boss structure.

Compared with prior art, the utility model has the following advantages：

First, it is easy to use：It can complete to assemble by the insertion between pipe fitting and rotating action, assembly technology letter It is single, while installation time can be also saved, save production cost.

2nd, cost is low：The cooperation of two pipe fittings is mainly by the first pipe fitting after the completion of spinning movement, and assembling Be buckled spacing design to the boss of the second pipe fitting is realized, it is not necessary to increase other accessories (such as clip), can be significantly Save product cost.

3rd, use scope is wide：The design can be used for the cooperation of plastic tube and plastic tube, and metal tube and plastic tube are matched somebody with somebody Close, selection is relatively broad, suitable for a variety of plastic materials and metal material.

4th, detachability is good：The utility model is detachable design, can repeatedly be assembled, if during dismounting with peace Assembly direction during dress can conversely be completed to dismantle.

5th, it is good to design matching：By setting the width and length of different boss, and the width and length of hollow slots Degree, can obtain different fit-up gaps, can so be allowed in assembling complete to have between latter two pipe fitting it is certain axial and The relative motion of radial direction, is adapted to different use demands.

Embodiment

The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.

Embodiment：

As shown in Figs. 1-5, the piecing devices of the utility model include the first pipe fitting 101, the second pipe fitting 102 and sealing Circle 103, by the way that the second pipe fitting 102 is inserted into the first pipe fitting 101, and carries out spinning movement to realize both match somebody with somebody Close, the first pipe fitting 101 is mainly by groove 401, hollow slots 402,403, the first pipeline main body 404 that is buckled and groove shell 405 What composition, wherein hollow slots 402 and groove 401 were connected to, it is jagged on the face of groove 401 between the two, it is in order to second When pipe fitting 102 assembles, the boss 501 of the second pipe fitting 102 can with the hollow slots 402 of rotational slide to the first pipe fitting, Buckle 403 is arranged in the position between groove 401 and hollow slots 402, and after the second pipe fitting is completed to rotate, it is limited Position, on the girth of whole first pipe fitting 101, groove 401, hollow slots 402 and 403 this integral locking structure of buckle are in uniform Distribution, according to the diameter of pipeline configuration, usually set 4~8.To ensure that two the effective of pipe fitting coordinate, prevent in work There is a phenomenon where the second pipe fitting 102 skids off the first pipe fitting 101 during work.

Second pipe fitting 102 is mainly made of boss 501, seal groove 502 and pipeline main body 503, the shape of boss 501 And 401 width of groove of width and the first pipe fitting matches, the width and height of boss 501 are slightly less than the width of groove 401 And height.Likewise, the width of boss 501 is also slightly less than the width (wall of hollow slots one side of hollow slots 402 on the first pipe fitting Face to be buckled 403 distance), and the height of boss 502 be larger than buckle 403 peaks to be buckled 403 opposite hollow outs The distance of groove side, so just can guarantee that the second pipe fitting will not skid off after the completion of assembling, also close on the second pipe fitting Sealing groove 502, for installing sealing ring 103.

The utility model connects two by the gripping mechanism that the first pipe fitting 101 and the second pipe fitting 102 cooperate A pipe fitting.Its assembly method is mainly：By the groove 401 of 501 the first pipe fitting of position alignment of boss of the second pipe fitting Put, be axially inserted into, after boss 501 is inserted into groove 401, then rotated, boss 501 is screwed in hollow slots 402 In, after boss 501 is snapped 403 and 402 side of hollow slots is stuck, assembling is completed.By setting different boss 501 Width and length, and the width and length of hollow slots 402, can obtain different fit-up gaps, can so be allowed in dress With completing have relative motion necessarily axially and radially between latter two pipe fitting.
