The insertion type pipeline joint is characterized in that A dentiform claw ring and a sealing element are arranged in the axial outside segment end hole of the direct plug jack respectively along the axial direction. An end cap and an outer screw at the end hole of the joint body are screwed together and the dentiform claw ring and the sealing element are pressed and positioned along the axial direction. A plurality of interval-shaped dentiform claw rings along the convex clavus of the radical direction are fastened on the external surface of the tube which is inserted in the plug jack, and the tube is positioned along the axial direction. The sealing element contacts and comprises the external surface of the tube, and the tube is sealed along the radial direction.

Description

The new plug-in pipe joint

The utility model relates to a kind of improved new plug-in pipe joint.

Traditional pipe joint needs to install with instrument, and the metallic pipe coupling screw thread is prone to wearing and tearing and corrosion and inconvenience and installs, and joint for plastic tube can not be high temperature resistant, high pressure resistant, easily leak, so that the life-span is short, and the cost height, and install and use inconvenience.

The purpose of this utility model is to overcome the defective and the deficiency of conventional pipe joint, provide a kind of manufacturing simple in structure, easy, good airproof performance, easy for installation, take over rapidly, the improved new plug-in pipe joint of not fragile, long service life.

The purpose of this utility model is based on following technological scheme realization:

The new plug-in pipe joint, include a joint body, joint body is provided with more than one and the pipe jack of plug-in mounting mutually, it is characterized in that: in the stomidium of the axial segmentum laterale of jack, put profile of tooth dog collar and Sealing successively vertically, end cap spins mutually with the outside thread at the stomidium place of joint body and profile of tooth dog collar and Sealing is located vertically and compresses, some intervals shape of the profile of tooth dog collar radially calvus of convex fastens with the outer surface that is inserted into the pipe in the jack and with the pipe axially locating, contact with the outer surface of pipe containing and pipe radially sealed of Sealing.

Joint body be provided with direction different with the pipe jack of plug-in mounting mutually, jack and diameter greater than its stomidium connect, end cap is provided with a convex that compresses Sealing vertically and turns over ring, calvus is along the annular body circle of the profile of tooth dog collar inclination elastic claw of convex tiltedly and radially from right to left or from left to right.。

Inwardly be shaped as along the annular body right side radially, be tilted to the left or the V-arrangement spring sheet inside, that be tilted to the right of calvus, calvus is trapezoidal or sector shape along the annular body circumferential shape, the lower end that contacts with outer tube surface of calvus is triangular shape or flexuose.

Advantage applies of the present utility model exists: because behind the pipe insertion tube joint, the pipe front end is spacing by the convex shoulder in the header body, the tooth of profile of tooth dog collar is strutted firmly promptly pipe by pipe, compress O-ring seals, pad, profile of tooth dog collar by end cap, pipe just organically combines as a whole with pipe joint, can not move axially, novel structure, make simple, sealing is reliable, the heat resisting and pressure resisting performance is good, installs quick and conveniently, does not need instrument, low, the long service life of cost.

The utility model is realized by the following drawings:

Fig. 1 is the erection drawing of new plug-in pipe joint of the present utility model;

Fig. 2 is the structural drawing of profile of tooth dog collar of the present utility model.

Fig. 3 Fig. 2 A-A sectional drawing.

Wherein the label among the figure is respectively: 1, joint body, 2, the profile of tooth dog collar, 3, pad, 4, O-ring seals, 5, end cap, 6, sleeve, 7, O-ring seals, 8,

pipe jack

11,11, jack, 12, stomidium, 51, convex turns over ring.

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

As shown in Figure 1, the new plug-in pipe joint, include a joint body 1, joint body is provided with more than one and pipe 8 jack 11 of plug-in mounting mutually, it is characterized in that: in the stomidium 12 of jack 11 axial segmentum laterales, put profile of tooth dog collar 2 and Sealing 7 successively vertically, end cap 5 spins mutually with the outside thread at stomidium 12 places of joint body 1 and profile of tooth dog collar 2 and Sealing 7 is located vertically and compresses, some intervals shape of the profile of tooth dog collar 2 radially calvus 21 of convex fastens with the outer surface that is inserted into the pipe 8 in the jack 12 and with the pipe axially locating, contact with the outer surface of pipe 8 containing and pipe radially sealed of Sealing 7.

Joint body 1 be provided with direction different with pipe 8 jack 11 of plug-in mounting mutually, jack 11 and diameter greater than its stomidium 12 connect, end cap 5 is provided with a convex that compresses Sealing 7 vertically and turns over ring 51, calvus 21 is along the annular body circle of the profile of tooth dog collar inclination elastic claw of convex tiltedly and radially from right to left or from left to right.。

As shown in Figure 2, inwardly be shaped as along the annular body right side radially, be tilted to the left or the V-arrangement spring sheet inside, that be tilted to the right of calvus scope, calvus 21 is trapezoidal or sector shape along the annular body circumferential shape, calvus 21 to contact the lower end with pipe 8 outer surfaces be triangular shape or flexuose.

Among Fig. 1, the left side be depicted as pipe 8 in the insertion tube joint, situation about assembling.Pipe 8 front ends are spacing by the convex shoulder of joint body 1, and the tooth of profile of tooth dog collar 2 is strutted firmly promptly pipe 8 by pipe, and the convex shoulder of end cap 5 is fixed O-ring seals 4, pad 3, profile of tooth dog collar 2, and pipe just can not move axially like this.

Fig. 1 top is depicted as the assembly process of pipe and pipe joint.Earlier profile of tooth dog collar 2 (tooth does not open), pad 3, O-ring seals 4 are put into joint body 1 successively, tighten end cap 5 again, with the convex shoulder place in the pipe 8 direct insertion tube joints, pipe just is connected as one securely with pipe joint.

For the limited pipe of intensity, can adorn a sleeve 6 earlier before inserting, sleeve plays a supportive role to pipe.

For temperature, the fluid that pressure is higher can be adorned an O-ring seals 7 at little convex shoulder place, with enhanced leaktightness circle 7, with enhanced leaktightness (seeing shown in Fig. 1 right side).

The improved new plug-in pipe joint that provides according to above-mentioned the utility model, it only needs profile of tooth dog collar, pad, O-ring seals are put into joint body successively when taking over, tighten end cap again, pipe only needs the spacing convex shoulder place in the direct insertion tube joint then, just firmly combines as a whole.

Therefore, in the utility model, profile of tooth dog collar front end is spacing by the convex shoulder in the joint body, tooth opens promptly pipe, pad is separated and spacing profile of tooth dog collar, O-ring seals is with pipe and pipe joint cabinet isolating seal, and end cap is fixed O-ring seals, pad, profile of tooth dog collar, takes special buttress thread to be connected with joint body.During adapter, earlier profile of tooth dog collar, pad, O-ring seals are put into joint body successively, tighten end cap again, the convex shoulder of end cap is with profile of tooth dog collar, pad, O-ring seals is fixed, then the spacing convex shoulder place in the direct insertion tube joint of pipe, just be connected as one with pipe joint securely, if pipe is in intensity limited (as plastic tube etc.), can adorn a sleeve earlier before pipe inserts, sleeve plays a supportive role to pipe, if fluid temperature (F.T.), pressure are higher, can refill an O-ring seals at little convex shoulder place, with enhanced leaktightness.
