Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of assembling pipe joint; Comprise assembling pipe joint body 1; Be provided with some ring-shaped steps 2 on the mouth of pipe inwall of said body 1 vertically; Be disposed with seal ring 3, seal joint 4, latch pressure ring 5, lock tooth snap ring 6 and lock ring 7 on the ring-shaped step 2 vertically, the said lock ring 7 axial forward end outside is formed with the locking button pin 9 of a plurality of radially evaginations of symmetry, and the mouth of pipe inwall of said body 1 is formed with the draw-in groove 11 corresponding with locking button pin 9; Be provided with stiffening ring 8 in the said draw-in groove 11, said stiffening ring 8 and draw-in groove 11 clampings.
Said stiffening ring 8 thickness are 1-3mm, and this stiffening ring 8 is an eyelet, and preferred Al-alloy products is difficult for getting rusty, and makes simply, and cost is lower.
Like Fig. 2, shown in Figure 3, the end of said locking button pin 9 forms a taper buckle 10, draw-in groove 11 clampings of said buckle 10 and mouth of pipe inwall.Lock ring 7 is provided with 2-4 bar raised line 13, and the mouth of pipe inwall of body 1 is formed with the axial notch 12 corresponding with raised line 13, and raised line 13 and axial notch 12 clampings on the lock ring 7 can prevent that lock ring 7 from rotating, thereby can carry out locking to other parts.Said buckle 10 ends are cammed surface, and the angle of inclination is the 86-89 degree, and the present invention is preferably 89 degree; When lock ring 7 pressurizeds, lock on the tooth snap ring 6 because buckle 10 is connected to, and 89 degree cammed surface are adopted in buckle 10 ends; Buckle 10 promptly can outwards squint; Then buckle 10 contacts tightlyer with draw-in groove 11, can prevent that the buckle 10 on the lock ring 7 from deviating from draw-in groove 11, thereby make sealability better.
Seal ring 3 of the present invention adopts outer flat interior circle seal ring; And seal ring is generally circular in the existing technology; Circular seal ring and inner-walls of duct are dot encapsulation; And put down outside being somebody's turn to do between interior circle seal ring 3 and the inner-walls of duct is face seal, and while ring-shaped step 2 is processed as downward-sloping, thereby makes sealing effect better.
Seal joint of the present invention 4 and seal ring 3 butts have improved the sealability of seal ring 3, and seal joint 4 is provided with the plane of inclination.
