Referring to fig. 1, in an embodiment of the present invention, the air duct 10 includes at least two duct segments 100, the duct segments 100 have a first end and a second end opposite to each other, the first end is provided with a plug connector 200, the second end is provided with a clamping member 300, and the clamping member 300 is provided with a clamping groove 310; the plug 200 of one of the segments 100 is inserted into the slot 310 of the other segment 100.

In particular, the ductwork 10 installed in a fire shaft is generally constructed by splicing sections of duct 100 to form a long supply duct. In this embodiment, each pipe segment 100 has the same structure, the pipe segment 100 has a first end and a second end which are opposite to each other, the plug connector 200 on the first end and the clip 300 on the second end are exposed, and the clip 300 is further provided with a clip groove 310. When a worker installs the fire-fighting shaft, the worker only needs to insert the plug connector 200 on one pipe section 100 into the clamping groove 310 on the other pipe section 100, so that a large operation space is not needed, and the area of the fire-fighting shaft can be effectively saved.

The pipe section 100 is generally made of metal, and in order to ensure the air tightness, the size and the interface standard of the air duct 10, the pipe section 100 must be prefabricated by a factory and cannot be processed on site by a worker. Regarding the shape of the pipe segment 100, the pipe segment 100 may be configured as a rectangular air pipe or a circular air pipe, and may also be configured as an oblate air pipe or an air pipe with other shapes, which is not limited herein.

Compare in the connected mode through flange joint between traditional pipeline section, the connected mode of this kind of grafting does not need very big operating space, can effectually save the area of fire control shaft, and simultaneously, the workman can be one section with 10 concatenation one ends of tuber pipe fastenings, the installation time of having saved of very big degree has improved work efficiency.

Referring to fig. 1 and 4, in an embodiment, the plug connector 200 includes a flared portion 210 and a plug portion 220 connected to the flared portion 210, an end of the flared portion 210 away from the plug portion 220 is connected to a first end, and the plug portion 220 is inserted into the slot 310.

Specifically, when the connector 200 of one segment 100 is inserted into the slot 310 of another segment 100, the insertion portion 220 is located in the slot 310 and is locked by the slot 310, so that the connector 200 cannot be easily removed from the slot.

Further, the end of the insertion part 220 is designed in a roll shape. Specifically, the end of the insertion part 220 is in a roll-shaped design, which facilitates production and processing, and at the same time, the roll-shaped design makes the curled edge have no burr, which is not easy to cut the hand of a worker during construction, and the insertion part 220 is not easy to loosen when being inserted into the slot 310. Of course, in other embodiments, the end of the insertion part 220 may be designed in other shapes, and is not limited in particular.

It is considered that, in the connection and fixation of two pipe segments 100 by means of insertion, one pipe segment 100 needs to be inserted into the other pipe segment 100, and therefore, the pipe inner diameters of the first end and the second end of the pipe segment 100 should be different, so that the first end of one pipe segment 100 can be inserted into the second end of the other pipe segment 100. In view of this, to solve the problem, the flared portion 210 may be gradually enlarged from the first end to the second end, so that the inner diameter of the first end is larger than that of the second end, the clamping member 300 is located outside the second end of the pipe segment 100, and after the flared portion 210 is gradually enlarged from the first end to the direction of the insertion portion 220, the plug connector 200 may be directly inserted into the slot 310 of the clamping member 300.

It should be noted that the clip 300 is a snap structure. Specifically, the pipe segment 100 with the seaming structure is convenient to process, and the two pipe segments 100 can be connected and fixed conveniently and firmly.

Referring to fig. 1 and fig. 2, in an embodiment, the locking member 300 includes a first bending portion 320, a second bending portion 330 and a locking portion 340, wherein the second bending portion 330 connects the first bending portion 320 and the locking portion 340; the first bending portion 320 is formed by bending the outer wall surface of the second end toward the direction close to the first end, the second bending portion 330 and the first bending portion 320 enclose the slot 310, the clamping portion 340 extends downward into the slot 310, and an insertion opening 350 for inserting the plug connector 200 into the slot 310 is formed between the clamping portion 340 and the first bending portion 320.

Specifically, when two pipe segments 100 are installed, the plug connector 200 of one of the pipe segments 100 is inserted into the slot 310 of the other pipe segment 100 through the socket 350, and after the plug connector 200 is inserted into the slot 310, the clamping portion 340 clamps the winding drum at the end of the plug-in portion 220 on the plug connector 200, so that the plug connector 200 cannot be separated from the slot 310, and thus the two pipe segments 100 are connected and fixed.

In one embodiment, the plug 200, clip 300 and spool piece 100 are integrally formed. By the design, three dies do not need to be designed for one pipe section 100, so that the design of the dies is reduced, the manufacturing procedures of the pipe section 100 are reduced, and the production efficiency is effectively improved.

Referring to fig. 1 and fig. 3, in an embodiment, the air duct 10 further includes a fastening member 400, and the fastening member 400 passes through the first bending portion 320, the inserting portion 220 and the engaging portion 340 to connect and fix the plug connector 200 and the engaging member 300.

The fastening member 400 may be a self-tapping screw, and a worker sequentially passes through the first bending portion 320, the inserting portion 220 and the fastening portion 340 from inside to outside through the self-tapping screw from the inside of the air duct 10 to secondarily fix the inserting member 200 and the fastening member 300. Of course, in other embodiments, the fastener 400 may be other kinds of screws, and is not limited herein.

Referring to fig. 1 to fig. 3, in an embodiment, the air duct 10 further includes a flexible sealing strip 500, and the flexible sealing strip 500 is attached to an inner wall surface of the locking groove 310.

Specifically, the flexible sealing strip 500 is made of a fireproof flexible material, and the flexible sealing strip 500 may be made of a fireproof flexible material such as carbonate fiber or ceramic fiber, which is not limited herein. The flexible sealing strip 500 is attached to the inner wall surface of the clamping groove 310, so that the air tightness of the two pipe sections 100 after being connected can be ensured, and air leakage is reduced.

The thickness of the tube segment 100 ranges from 0.75mm to 1.2mm according to any of the embodiments described above.

Specifically, for the area size of the fire-fighting shaft, the air pipes 10 with corresponding pipe diameters and the pipe sections 100 with different pipe diameters are arranged, and the wall thicknesses of the pipe sections 100 are also different. Currently, the tube segments 100 used conventionally have three thicknesses of 0.75mm, 1.0mm and 1.2 mm.
