Detailed Description
The technical solution of the present invention is described below with reference to the accompanying drawings and examples.
example 1: as shown in fig. 1 to 4, in the mortise and tenon joint structure for pipelines according to this embodiment, two ends of each pipeline 1 are respectively provided with a butt joint 2, each butt joint 2 includes a plurality of protrusions 3 and notches 4 arranged alternately, the bottom of each protrusion 3 and the bottom of each notch 4 are flat and perpendicular to the length direction of the pipeline 1, the height of each protrusion 3 is equal to the depth of each notch 4, so that after the protrusions 3 are matched with the notches 4, the protrusions 3 can flatly jack the bottom of the notches 4, and the jacked performance of the protrusions is improved by increasing the stressed surface. Two adjacent pipelines 1 are butted by adopting two pairs of joints 2, a lug 3 on one pair of joints 2 is matched with a notch 4 on the other pair of joints 2, after the two butt joints are butted, a sealing ring 5 is sleeved on the outer side of the two butt joints for sealing, and the sealing ring 5 is made of stainless steel materials.
Specifically, the bumps 3 are parallelogram, and all the bumps 3 on a pair of joints 2 incline towards the same rotation direction. Wherein, two inclined planes of lug 3, the definition wherein is the inclined plane of acute angle with the contained angle on 4 bases of notch 6, and another inclined plane is positive 7, two mutually support on the butt joint 2, be equipped with stopping tooth 8 on the positive 7 of the lug 3 on the butt joint 2, be equipped with on the positive 7 of the lug 3 on another butt joint 2 with stopping tooth 8 complex stopping draw-in groove 9, the positive 7 on the butt joint 2 is mutually supported, and pipeline 1 is the PE pipe, has certain elasticity, and stopping tooth 8 just blocks in stopping draw-in groove 9, avoids two butt joints 2 to loosen. Here, it should be mentioned that, in order to make it easier to screw the projection 3 into the recess 4, the sides of the projection 3 may be provided with an arc shape, which facilitates the mounting.
Specifically, the inner side wall of the convex block 3 is flush with the inner wall of the pipeline 1, the outer wall of the convex block 3 is slightly lower than the outer wall of the pipeline 1, an annular groove 10 is formed at the joint of the two pairs of connectors 2 after being butted, the sealing ring 5 is sleeved in the groove 10 in a matching manner, the sealing ring 5 is prevented from moving, the sealing ring 5 plays a role in sealing and tensioning the convex block 3, and the convex block 3 is prevented from turning outwards.
During installation of the embodiment, the sealing ring 5 is firstly sleeved in the butt joint 2, then the two butt joint 2 are well butted, and after the butt joint 2 is well butted, the sealing ring 5 is just sleeved at the butt joint position of the two butt joint 2.
In the embodiment, the two pairs of joints 2 are respectively provided with the parallelogram-shaped convex blocks 3 and the notches 4, the two pairs of joints 2 are butted while rotating when the pipelines 1 are butted, and the two pairs of joints 2 are butted after rotating to a certain angle, and the pipelines 1 are not easy to rotate after being buried, so that the pipelines 1 can be prevented from loosening and leaking water due to axial tension; the butt-joint surfaces of the convex block 3 and the concave opening 4 are flat and vertical to the length direction of the pipeline 1, and the thickness of the convex block 3 is almost equal to that of the pipeline 1, so that the bearable jacking force at the joint is large, and the butt-joint head 2 is not easy to be damaged by jacking.
Example 2: referring again to fig. 5, the difference from embodiment 1 is that: the butt joint department at every pipeline 1 both ends is equipped with sand grip 11 and recess 12 respectively, and sand grip 11 and recess 12 mutually support, improve the leakproofness of interface between two pipelines 1 like this.
