[0033] Due to the setting of first pipeline 100, second pipeline 200 and locking assembly 300, and the setting of flange sleeve 110 on first pipeline 100, flange sleeve 110 and the outer peripheral wall between first pipeline 100 form a slot 112, second pipeline 200 is provided with connecting flange 210, connecting flange 210 is provided with clamping groove 211, by the cooperation between the above-mentioned components, not only can realize the quick positioning connection of first pipeline 100 and second pipeline 200, simplify installation process, improve the convenience and efficiency of pipeline connection, but also can reinforce the connecting place of first pipeline 100 and second pipeline 200, enhance the stability and sealing between first pipeline 100 and second pipeline 200.

[0034] Specifically, by arranging the flange sleeve 110 on the first pipe 100 close to one end of the second pipe 200, and forming a slot 112 for connecting the second pipe 200 between the inner circumferential wall of the flange sleeve 110 and the outer circumferential wall of the first pipe 100, so that one end of the second sleeve can be inserted into the slot 112, wherein the width of the slot 112 is matched with the thickness of the second pipe 200, so that the second pipe 200 can be tightly attached to the outer circumferential wall of the first pipe 100 after being inserted into the slot 112, which not only ensures the stability of the connection between the first pipe 100 and the second pipe 200, but also enhances the sealing between the first pipe 100 and the second pipe 200.

[0036] Since the locking assembly 300 is provided with the first shell 310, the rotating shaft 320, the second shell 330 and the fastener 340, and the first shell 310 is provided with the connecting seat 311 for mounting the rotating shaft 320, the first shell 310 is provided with the first fastening part 312 and the first semicircular annular groove 313, the second shell 330 is provided with the second fastening part 331 and the second semicircular annular groove 332, and through the cooperation between the above-mentioned components, not only can the detachable and quick installation and disassembly of the locking assembly 300 be realized, but also the maintenance and adjustment of the housing building electromechanical installation convenient type pipe connecting device can be facilitated, and the annular limiting constraint of the pipe connecting part can be formed through the first circular annular limiting groove, so as to realize the reinforcement of the connecting part of the first pipe 100 and the second pipe 200, and enhance the stability and sealing performance between the first pipe 100 and the second pipe 200.

[0037] Specifically, the first shell 310 and the second shell 330 are rotationally connected through the rotating shaft 320, so that the second shell 330 can be rotated to open or close around the rotating shaft 320, facilitating rapid sleeving outside the connection after the first pipeline 100 and the second pipeline 200 are preliminarily clamped, and then the first fastening part 312 and the second fastening part 331 are locked through the fastener 340 (such as a bolt and a nut cooperation), forming a surrounding fastening force on the connection of the first pipeline 100 and the second pipeline 200, and improving the integrity of the connection structure. The first circular annular limiting groove formed by the first semicircular annular groove 313 and the second semicircular annular groove 332 is provided to realize annular limiting and sealing enhancement of the flange sleeve 110 and the connecting flange 210 at the connection of the first pipeline 100 and the second pipeline 200.

In addition, the limiting rod 350 can be provided with one or more according to actual needs, and the construction personnel can select the most suitable limiting channel according to the actual construction environment, so as to insert the limiting rod 350 into the first circular limiting groove.

[0044] In the preferred embodiment, the first sealing ring 113 is arranged in the insertion slot 112.
