DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 - Figure 5 As shown, a galvanized air duct that is easy to splice includes a galvanized air duct body 1. Adjacent galvanized air duct bodies 1 are fixedly connected together by a splicing mechanism 2, and the splicing mechanism 2 includes a splicing frame 5, a silicone sealing frame 7, a concave plate 8, a two-way adjustment screw 11, a movable rod 14 and a clamping rod 17. The two side walls of the splicing frame 5 are respectively fixedly connected with the silicone sealing frame 7, and the top and bottom surfaces of the splicing frame 5 are respectively fixedly connected with the concave plate 8. The two-way adjustment screw 11 is movably connected to the recess of the concave plate 8 through the rotating rods 12 at both ends, and the two movable rods 14 are respectively movably connected to the two-way adjustment screw 11 through the screw holes 15 on the front end wall. A group of symmetrical clamping rods 17 are also fixedly connected to the opposite walls of the two movable rods 14.

[0022] like Figure 3 As shown, a set of symmetrical connecting blocks 3 are fixedly mounted on the top and bottom surfaces of the left and right ends of the galvanized air duct body 1, and a clamping hole 4 is opened on the front wall of the connecting block 3. The clamping hole 4 opened on the front wall of the connecting block 3 installed on the galvanized air duct body 1 is used to cooperate with the use of the clamping rod 17. After the clamping rod 17 is inserted into the clamping hole 4, the two galvanized air duct bodies 1 can be connected together.

[0023] like Figure 4 As shown, sealing grooves 6 are respectively provided on the left and right side walls of the splicing frame 5, and silicone sealing frames 7 are fixedly installed in the sealing grooves 6. The opposite ends of the adjacent galvanized air duct bodies 1 are respectively inserted into the sealing grooves 6 and tightly adhere to the silicone sealing frames 7. When splicing, the opposite ends of the two galvanized air duct bodies 1 to be spliced ​​are respectively inserted into the sealing grooves 6 provided on the left and right side walls of the splicing frame 5, and tightly adhere to the silicone sealing frames 7 installed in the sealing grooves 6. This can ensure the sealing of the splicing part of the two galvanized air duct bodies 1 after splicing, and prevent the problem of gas leakage at the splicing part of the galvanized air duct bodies 1 when conveying gas;

[0024] like Figure 5 As shown, the top and bottom surfaces of the splicing frame 5 are respectively fixedly mounted with concave plates 8, and rotation holes 9 are respectively opened on the front and rear side walls of the recess of the concave plate 8. A limited sliding opening 10 is also opened on the bottom surface of the recess of the concave plate 8. The rotation holes 9 opened on the front and rear side walls of the recess of the concave plate 8 are used to cooperate with the rotating rod 12 to realize the rotation operation, and the limited sliding opening 10 opened on the bottom surface of the recess of the concave plate 8 is used to cooperate with the limited sliding bar 16 to realize the sliding operation;

[0025] like Figure 5 As shown, the front and rear ends of the two-way adjustment screw 11 are respectively fixedly mounted with a rotating rod 12, and the rotating rod 12 is movably mounted in the rotating hole 9, and a hand-tightening knob 13 is also fixedly mounted on the outer end wall of the rotating rod 12 at one end. After the opposite ends of the two galvanized air duct bodies 1 are respectively inserted into the sealing groove 6, the hand-tightening knob 13 at one end of the concave plate 8 installed on the top and bottom surfaces of the splicing frame 5 is rotated in turn. The hand-tightening knob 13 will drive the rotating rod 12 to be realized in the rotating hole 9, and the rotating rod 12 will drive the two-way adjustment screw 11 to rotate;

[0026] like Figure 5 The cam 16 is fixed on the bottom surface of the movable rod 14 and the limit slide 16 is movably installed in the limit slide 10. The outer wall of the movable rod 14 is fixedly installed with a group of symmetrical clamping rods 17, and the clamping rods 17 are inserted into the clamping holes 4. Under the rotation drive of the two-way adjusting screw 11, the front and rear symmetrical movable rods 14 will respectively pass through the screw holes 15 opened on the front wall to make opposite movements in the recess of the concave plate 8 along the two-way adjusting screw 11, and the limit slide 16 will slide in the limit slide 10 until the symmetrical clamping rods 17 installed on the outer wall of the movable rod 14 are respectively inserted into the clamping holes 4 opened on the front wall of the connecting block 3 installed on the adjacent galvanized duct body 1. In this way, the two galvanized duct bodies 1 can be quickly spliced ​​and fixed together.

[0027] It should be noted that the present invention is a galvanized air duct that is easy to splice. When two adjacent galvanized air duct bodies 1 need to be spliced ​​together for use, the opposite ends of the two galvanized air duct bodies 1 are respectively inserted into the sealing grooves 6 opened on the left and right side walls of the splicing frame 5, and the end walls of the galvanized air duct body 1 are tightly pressed against the silicone sealing frame 7 installed in the sealing groove 6. In this way, the sealing of the splicing part after the two galvanized air duct bodies 1 are spliced ​​can be guaranteed, and the problem of gas leakage at the splicing part of the galvanized air duct body 1 when conveying gas can be prevented. Then, the hand-tightening knobs 13 on the front end walls of the concave plates 8 installed on the top and bottom surfaces of the splicing frame 5 are rotated in turn. The hand-tightening knobs 13 will drive the rotating rod 12 to rotate in the rotating holes 9 opened on the front and rear side walls in the notch of the concave plate 8. The rotating rod 12 will drive the two-way adjusting screw 11 to rotate in the recess of the concave plate 8. At this time, driven by the rotation of the two-way adjusting screw 11, the front and rear symmetrical movable rods 14 will respectively pass through the screw holes 15 opened on the front end wall along the two-way adjusting screw 11 to make opposite movement operations in the recess of the concave plate 8 until the clamping rod 17 installed on the outer wall of the movable rod 14 is inserted into the clamping hole 4 opened on the front end wall of the corresponding connecting block 3 installed on the two galvanized air duct bodies 1, and the hand-tightening knob 13 can no longer be rotated. The two galvanized air duct bodies 1 can be spliced ​​and fixed together, thereby achieving the purpose of quickly sealing and splicing the galvanized air duct bodies 1. The splicing operation is simple and fast, which not only improves work efficiency, but also brings convenience to the subsequent disassembly and replacement of the galvanized air duct body 1.
