Description

Technical Field

[0001] This utility model relates to the field of duct splicing technology, and more specifically, to a high-efficiency internally insulated metal duct rapid splicing construction device. Background Technology

[0002] Air ducts are piping systems used for air transport and distribution. There are two main types: composite ducts and inorganic ducts. They can be classified according to cross-sectional shape and material. Stainless steel duct fabrication involves applying sealant to seams such as joints, rivet seams, and the four corners of flanges. Metal ducts are made of various metal materials, commonly including galvanized iron and stainless steel. With the continuous development of the storage tank industry, more and more industries and enterprises are using storage tanks, and more and more companies are entering the storage tank industry. Composite ducts are composed of various inorganic or organic materials and are classified into different types according to their composition, but they are mostly lightweight, porous, and have high thermal resistance.

[0003] Chinese Patent Announcement No. CN220706689U discloses a ventilation duct splicing device. This solution uses two limiting brackets to engage during splicing, allowing the duct flanges to be pre-inserted into the receiving cover on both sides of the duct during installation. Then, by pushing the limiting brackets towards the center, the two brackets are fully engaged on the two ducts to be spliced, achieving alignment of adjacent ducts and significantly improving splicing efficiency. At this point, the duct flanges adhere to the sealing strips on the partition plate. Tightening the first and second bolts sequentially completes the secure connection of the duct, greatly improving the stability and convenience of duct splicing. Simultaneously, the sealing performance is also significantly improved, which is beneficial for long-term use in high-pressure ventilation systems. However, in practical implementation, the following drawbacks exist: multiple sets of bolts and nuts are required for connection during installation, which is time-consuming and results in low installation efficiency.

[0004] Therefore, a high-efficiency, rapid splicing construction device for internally insulated metal ducts is proposed to address the above problems. Utility Model Content

The outer surfaces of the first and second metal ducts are movably connected to a splicing mechanism. The splicing mechanism includes two positioning plates, each with a connecting rod fixedly connected to its lower end. Four reinforcing plates are fixedly connected to the outer surfaces of the two connecting rods. The lower ends of the two connecting rods are fixedly connected to a splicing assembly.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This solution utilizes a splicing mechanism and splicing components, employing a bidirectional lead screw and guide rod to achieve rapid clamping and connection of ducts. A rocker arm drives the bidirectional lead screw to rotate, causing a moving block to slide inwards synchronously along the guide rod.

[0028] Example:

[0029] Please see Figure 1-5 A high-efficiency internally insulated metal duct rapid splicing construction device includes a metal duct 1 and a metal duct 2. The outer surfaces of the metal duct 1 and the metal duct 2 are movably connected to a splicing mechanism 3. The splicing mechanism 3 includes two positioning plates 31. The lower ends of the two positioning plates 31 are fixedly connected to connecting rods 32. The outer surfaces of the two connecting rods 32 are fixedly connected to four reinforcing plates 33. The lower ends of the two connecting rods 32 are fixedly connected to a splicing assembly 34. The lower part of the splicing assembly 34 is fixedly connected to two sealing components 35. The two sealing components 35 are movably connected to bolts and nuts 36 inside.

[0030] This solution connects two positioning plates 31 and splicing components 34 together using two connecting rods 32. The two positioning plates 31 can be used to quickly fix the device above the duct installation position to fix the position of the device. After fixing, the splicing components 34 and two sealing components 35 can be used to quickly splice metal duct 1 and metal duct 2.

[0031] Please see Figure 2-5 The sealing assembly 35 includes a U-shaped plate 351, a sealing strip 352 is fixedly connected to the inner surface of the U-shaped plate 351, a connecting plate 353 is fixedly connected to the lower end of the U-shaped plate 351, and a round hole 354 is opened at the left end of the connecting plate 353.

[0032] The splicing assembly 34 includes a housing 341, the upper end of which is fixedly connected to the lower ends of two connecting rods 32. Guide rods 343 are fixedly connected to the front and rear walls of the inner cavity of the housing 341. Control components 342 are slidably connected to the outer surfaces of the two guide rods 343.

[0033] The control component 342 includes a rocker arm 3421. A bidirectional lead screw 3422 is fixedly connected to the right end of the control component 342. Two moving blocks 3423 are threadedly connected to the outer surface of the bidirectional lead screw 3422. Slider blocks 3424 are fixedly connected to both ends of the two moving blocks 3423. The inner surfaces of the four sliders 3424 are slidably connected to the outer surfaces of the two guide rods 343 respectively. A connecting seat 3425 is fixedly connected to the upper end of the two moving blocks 3423. The lower ends of the two connecting seats 3425 are fixedly connected to the upper ends of the two U-shaped plates 351 respectively. A rotating seat 3426 is rotatably connected to the right end of the bidirectional lead screw 3422. The right end of the rotating seat 3426 is fixedly connected to the right wall of the inner cavity of the outer shell 341.

[0034] This solution involves installing two U-shaped plates 351, corresponding to the size of the metal duct, at the lower end of the connecting seat 3425. The device is then fixed to the ceiling above the duct using a positioning plate 31. Metal duct 1 and metal duct 2 are placed between the two U-shaped plates 351. The rocker arm 3421 is rotated clockwise to drive the bidirectional lead screw 3422 to rotate, causing the moving block 3423 to move inward synchronously along the guide rod 343. This causes the U-shaped plates 351 to clamp the outer wall of the duct, and the sealing strip 352 to be pressed tightly against the gap. Finally, bolts are passed through the round holes 354 of the two connecting plates 353, and nuts are tightened to ensure a stable connection.

[0035] Working principle: When splicing metal ducts using the device, two U-shaped plates 351 corresponding to the size of the metal ducts are fixed to the lower ends of two connecting seats 3425 respectively. Metal duct 1 and metal duct 2 are placed between the two U-shaped plates 351, ensuring the seam between them is in the middle of the sealing strip 352. Then, the rocker arm 3421 is rotated, causing the double-acting screw 3422 to rotate under the action of the rocker arm 3421 and in cooperation with the rotating seat 3426. Because the threads at both ends of the double-acting screw 3422 are opposite, when it rotates... This will drive two moving blocks 3423 to simultaneously move four sliders 3424 inward along the outer surface of the two guide rods 343, causing the two U-shaped plates 351 to move inward simultaneously, thereby fixing the metal duct 1 and the metal duct 2 together, allowing them to be quickly spliced ​​together. At this time, the bolts in the bolt and nut 36 are passed through the two round holes 354, and then the nuts are tightened to fix the two connecting plates 353 together, further enhancing the reliability of the connection. At this time, the sealing strip 352 will be tightly attached to the gap between the two to improve the sealing performance of the duct splicing and prevent air leakage at the gap.

[0036] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
