Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 and fig. 2, this embodiment discloses a mining PE pipe connection structure, including body 1, end periphery fixedly connected with at this body 1 keeps off ring 2, and rotationally the cover is equipped with movable flange 3 in the periphery of body 1, keep off ring 2 and be provided with the ring channel far away from the one end of movable flange 3, the embedded sealing washer 21 that is equipped with of this ring channel, the circumference equipartition has six connecting holes 31 on movable flange 3, still the cover is equipped with spacing ring 4 in the periphery of body 1, a plurality of beads 11 have been arranged in the periphery circumference of body 1, this bead 11 sets up along the axis direction of body 1, a plurality of spouts with bead 11 adaptation have been arranged in the inner circumference of spacing ring 4, this bead 11 and spout one-to-one, and bead 11 slides and wears to establish in corresponding spout, make the circumference position between spacing ring 4 and the body 1 fixed.

One side of the movable flange 3 close to the baffle ring 2 is provided with a groove for accommodating the baffle ring 2, one side of the movable flange 3 far away from the baffle ring 2 is provided with a boss 32, the outer diameter of the boss 32 is larger than the inner diameter of the groove, three threaded holes 33 are uniformly distributed in the circumferential direction on the boss 32, one end of the limiting ring 4 close to the movable flange 3 extends outwards along the radial direction to form a connecting plate, three long circular arc holes 41 are uniformly distributed in the circumferential direction on the connecting plate, the long circular arc holes 41 are in one-to-one correspondence with the threaded holes 33, the radian of each long circular arc hole 41 is larger than the angle (namely 60 degrees) between two adjacent connecting holes 31, and the angle (namely 120 degrees) between two adjacent threaded holes 33 is larger than the radian of each long.

The connection mode of the mining PE pipe connection structure of the embodiment is as follows: during connection, the baffle rings 2 of the two pipelines are aligned with each other, then the movable flanges 3 of the two pipelines are rotated, so that the connecting holes 31 of the two movable flanges 3 are aligned one by one, meanwhile, the threaded holes 33 are ensured to be positioned in the corresponding long circular arc-shaped holes 41, and the two movable flanges 3 are assembled and fixed by using bolts; then, the limiting ring 4 is slid to enable the end part of the connecting plate to be abutted against the end part of the movable flange 3, and then screws penetrate through the long circular arc-shaped holes to be in threaded connection with the corresponding threaded holes, so that the circumferential relative position between the movable flange 3 and the pipe body 1 is fixed.
