Inner peripheral surface I 4b of the rack structure tilted on left clip 4 can the outer tube wall of stuck fast metal tube A, effectively prevent pipe joint
Metal tube outer wall skids.
With reference to shown in Fig. 2, the latch 53 on right clip 5 is obtained by following version: described right clip 5 interior
Form the arc fin 51 of five axially spaced-apart distributions on side face II 5b, each described arc fin 51 all offers edge
Several arcuate grooves 52 that this arc fin length direction is spaced apart, thus form institute at two arcuate grooves 52 of arbitrary neighborhood
State latch 53.And the axial cross section of described arc fin 51 is triangle.
In this example, described sealing ring 3 is rubber seal.And on the inwall of sealing ring 3, form radial direction convex
Seal lip ring 3c, to improve the sealing between this pipe joint and pipeline outer wall further.
Described clamp device 2 includes the lug 21 being respectively arranged on described opening 1a both sides annular outer cover 1 a pair, described
Lug 21 is outwards to be bent to form from opening part by annular outer cover 1, and the end of bending part is fixedly welded on annular outer cover；Often
The bending place of individual lug is symmetrically arranged with the hole, location 22 of two axially spaced-aparts respectively, and hole, described location 22 is that width dimensions is equal
Even consistent strip hole, and the length two ends of described strip hole are semicircular structure, are equipped with one respectively in each lug 21
Root round steel 23 (having two lugs, so one has two round steel 23), wherein offers on a round steel 23 and positions hole accordingly
Corresponding two cross keyhole 26 (smooth inner wall), and another root round steel 23 offers two screwed holes corresponding with hole, location accordingly
25, cross the aperture slightly larger than screwed hole 25, the aperture of keyhole 26, the described axially bored line crossing keyhole and screwed hole 25 and described round steel
The axis of 23 is arranged vertically, two bolts 24 be horizontally through the hole, location 22 of correspondence and cross keyhole 26 and with described screwed hole 25
Threaded, thus two round steel 23 are linked together.
With reference to shown in Fig. 2, during actual application, this pipe joint is set in two pipelines (metal tube A and non-metallic pipe B, wherein
Non-metallic pipe is generally plasticity pipeline) joint, rotate described bolt 24 by die nut and make annular outer cover 1 opening part
Gap diminish, and then make annular outer cover 1 that sealing ring 3 is formed radially inner chucking power, shell is fastened, and and then makes close
The inwall of seal 3, left clip 4 and right clip 5 shrinks to clamp the outer wall realization sealing placing two pipelines therein even
Connect.
In this example, described right clip 5 is copper.
Certainly, above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow people's energy
Solution much of that content of the present utility model is also implemented according to this, can not limit protection domain of the present utility model with this.All according to this
