[0002] Air ducts play roles such as keeping the air fresh, realizing ventilation and air change, reducing the indoor temperature, and reducing environmental pollution. Therefore, for buildings with a relatively large depth, it is very important to configure air ducts inside. It is relatively difficult to transport long and large air ducts. Therefore, usually, metal air ducts are divided into multiple small sections and then connected using an installation structure.

[0003] For the existing prefabricated installation structure of metal air ducts, when installing, most of them achieve the overall connection between the installation structures through multiple groups of bolts. During the subsequent disassembly and maintenance process, it takes a long time to achieve the overall disassembly between the air ducts, and the overall operation is relatively cumbersome. Therefore, a prefabricated installation structure of a metal air duct is needed to assist in solving this problem. Summary of the Utility Model

[0026] This specific implementation is a prefabricated installation structure for metal air ducts. As Figure 1 , Figure 2 and Figure 3 shown, the prefabricated installation structure for metal air ducts includes an air duct body 1. Sealing strips 9 are prominently provided at both ends of the air duct body 1. The sealing strips 9 at both ends are arranged staggeredly, and the two sealing strips 9 are cooperatively sealed. By providing the sealing strips 9, the overall sealing performance at the connection of the two air duct bodies 1 can be ensured during operation, and situations such as the overall leakage of gas during operation can be avoided as much as possible. A first protruding plate 2 and a second protruding plate 3 are respectively installed at both ends of the air duct body 1. The second protruding plate 3 is in an L-shaped plate structure, and an installation cavity for installation is reserved between the two second protruding plates 3.

[0027] Positioning holes 101 are opened at the top and bottom of the installation cavity. A positioning component 10 is prominently provided on the outer side edge of the first protruding plate 2. The positioning component 10 is cooperatively clamped with the positioning holes 101. The positioning component 10 includes an installation block 11 fixed on the first protruding plate 2. Positioning pins 12 are symmetrically and slidably provided inside the installation block 11. The positioning pins 12 are cooperatively inserted into the positioning holes 101. Sliding cavities for the positioning pins 12 to slide are opened at both ends of the installation block 11. A top spring 14 for assisting in pushing the positioning pins 12 is installed in the sliding cavity. A winding wheel 15 is rotatably provided at the middle section of the installation block 11. The positioning pins 12 are fixedly connected to the winding wheel 15 through a connecting belt 13. A handle 16 is rotatably provided on the winding wheel 15. The handle 16 is in a U shape. One end of the handle 16 is inserted and installed on the winding wheel 15. Fixing holes 17 are symmetrically opened on the installation block 11. One end of the handle 16 is cooperatively inserted into the fixing holes 17.

[0028] Through the cooperation between the positioning component 10 and the positioning hole 101, the positioning pin 12 on the positioning component 10 corresponds to the positioning hole 101, is pushed, and the positioning pin 12 is plugged and installed in the positioning hole 101, thereby completing the overall positioning between the positioning component 10 and the positioning hole 101. When it is necessary to perform auxiliary disassembly between the positioning component 10 and the positioning hole 101, one end of the handle 16 is pulled out of the fixing hole 17 as a whole and rotated to drive the handle 16 to rotate as a whole. During the rotation of the handle 16, the ejection spring 14 is compressed as a whole, thereby retracting the positioning pin 12 from the positioning hole 101 as a whole, and plugging one end of the handle 16 into the fixing hole 17, thereby completing the overall limiting of the positioning pin 12 and facilitating subsequent overall removal, which can avoid the overall installation of the metal air duct through multiple sets of bolts as much as possible, ensure the difficulty of overall disassembly during subsequent metal air duct maintenance, and improve the overall maintenance efficiency of the metal air duct.

[0029] Reference Figure 1 , Figure 2 and Figure 4 As shown, mounting holes 4 are drilled and installed at the corners of the second protruding plate 3, and fixing components 5 are installed at the four corners on the side of the first protruding plate 2 away from the second protruding plate 3. The fixing components 5 are plugged into the mounting holes 4, and the fixing components 5 include an adjusting cylinder 6 rotatably arranged on the first protruding plate 2, an embedded ring is protrudingly arranged at the outer edge of the adjusting cylinder 6, a tightening rod 7 is threadedly installed on the adjusting cylinder 6, a rotating knob 61 is protrudingly arranged on the side of the adjusting cylinder 6 away from the tightening rod 7, a sliding groove is opened on the tightening rod 7, a positioning pin rod 8 is hingedly installed in the sliding groove, and the adjusting cylinder 6 is embedded and installed on the first protruding plate 2 through the embedded ring.

[0030] Through the cooperation between the set mounting hole 4 and the fixing component 5, the mounting hole 4 on one duct body 1 is plugged with the fixing component 5 on the other duct body 1, and the positioning pin rod 8 passes through the mounting hole 4 and extends out of the second protruding plate 3, the positioning pin rod 8 is rotated, the adjusting tube 6 and the tightening rod 7 are threadedly matched, and the positioning pin rod 8 is fitted on the outer edge of the second protruding plate 3, and at this time, the rotating knob 61 is continued to be rotated, and the adjusting tube 6 drives the adjusting tube 6 to continue to rotate, so that the positioning pin rod 8 is stably and tightly attached to the second protruding plate 3, thereby completing the secondary positioning processing between the two duct bodies 1, and can achieve the overall stable tightening processing between the four corners of the two duct bodies 1 during work, further improving the overall connection tightness of the metal duct, and ensuring the smooth progress of subsequent work.

[0031] Working principle:

[0032] Align the positioning pin 12 on the positioning component 10 with the positioning hole 101, push it, and insert the positioning pin 12 into the positioning hole 101, thus completing the overall positioning between the positioning component 10 and the positioning hole 101, and preliminarily positioning and fastening the two air duct bodies 1. Insert the mounting hole 4 on one air duct body 1 into the fixing component 5 on the other air duct body 1 in a matching manner, and make the positioning pin rod 8 pass through the mounting hole 4 and extend out of the second protruding plate 3. Rotate the positioning pin rod 8, adjust the threaded fit between the adjusting cylinder 6 and the tension rod 7, and make the positioning pin rod 8 fit against the outer side edge of the second protruding plate 3. At this time, continue to rotate the rotating knob 61, and the adjusting cylinder 6 drives the adjusting cylinder 6 to continue rotating, so that the positioning pin rod 8 is stably pressed against the second protruding plate 3, thus completing the secondary positioning process between the two air duct bodies 1.

[0033] When it is necessary to assist in disassembling between the positioning component 10 and the positioning hole 101, pull one end of the handle 16 out of the fixing hole 17 as a whole and rotate it to drive the handle 16 to rotate as a whole. During the rotation of the handle 16, the ejecting spring 14 is driven to be compressed as a whole, so as to retract the positioning pin 12 from the positioning hole 101 as a whole, and insert one end of the handle 16 into the fixing hole 17, thus completing the overall limit of the positioning pin 12 and facilitating the subsequent overall removal.
