Description

Technical Field

[0001] This utility model belongs to the field of flue installation technology, specifically, it relates to a sealing device for the connection between the upper and lower sections of a flue. Background Technology

[0002] Based on practical experience in multiple construction projects, prefabricated flues or exhaust ducts offer centralized manufacturing, superior quality, and convenient and quick construction. Compared to brick-built and plastered flues, they improve quality while saving costs, leading to their increasingly widespread use in projects. However, when the building height is too high, the required prefabricated flues or exhaust ducts become excessively long. Since the production, transportation, and installation of excessively long prefabricated flues or exhaust ducts are inconvenient, it is necessary to produce, transport, and install them in sections. When installing flues or exhaust ducts in sections, the joints must support the load of the upper section and the joints must be sealed to prevent smoke and air leakage.

[0003] Most existing flue gas ducts are quite cumbersome to disassemble and install, requiring multiple bolts and specific tools, making them inconvenient for on-site installation. Furthermore, their sealing performance is poor after connection and installation.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A sealing device for the connection between the upper and lower sections of a flue, comprising a first connecting part;

[0007] A second connecting portion is disposed on one side of the first connecting portion. A disassembly and assembly mechanism is provided on both the first and second connecting portions. A sealing mechanism is provided on the disassembly and assembly mechanism. An installation hole is provided on the outer wall of one side of the first connecting portion.

[0008] A mounting rod is fixedly connected to one side of the outer wall of the second connecting part. A positioning hole is provided on the outer wall of the mounting rod. A through hole is provided on the outer wall of the first connecting part. A positioning rod is slidably disposed inside the through hole. A connecting plate is fixedly connected to the end of the positioning rod away from the outer wall of the first connecting part. A spring is fixedly connected to the side of the connecting plate near the outer wall of the first connecting part. The end of the spring away from the outer wall of the connecting plate is fixedly connected to the outer wall of the first connecting part. A force-bearing plate is fixedly connected to the outer wall of the connecting plate. A sliding hole is provided at the top of the first connecting part. A sliding rod is slidably disposed on the inner wall of the sliding hole. A supporting connecting plate is fixedly connected to the outer wall of the sliding rod. A top block is fixedly connected to the end of the supporting connecting plate away from the outer wall of the sliding rod. A limit plate is fixedly connected to the end of the sliding rod away from the supporting connecting plate.

[0009] In a preferred embodiment of the present invention, the sealing mechanism includes a first sealing ring fixedly connected to the outer wall of one end of the first connecting part, a second sealing ring fixedly connected to the outer wall of one end of the second connecting part, and a sealing groove formed on the outer wall of one end of the first connecting part.

[0010] In a preferred embodiment of this utility model, the number of mounting rods is four, and the mounting rods are distributed in a symmetrical structure in pairs on one end of the outer wall of the second connecting part.

[0011] In a preferred embodiment of this utility model, the outer wall of the mounting rod is fitted to the inner wall of the mounting hole, and the inner wall of the positioning hole is fitted to the outer wall of the positioning rod.

[0012] In a preferred embodiment of this utility model, the outer wall of the end of the force-bearing plate away from the connecting plate is provided with an inclined surface, and the outer wall of the top block is fitted to the inclined surface.

[0013] In a preferred embodiment of this utility model, the outer wall of the first sealing ring and the inner wall of the second connecting part are properly fitted together.

[0014] In a preferred embodiment of this utility model, the outer wall of the second sealing ring is properly fitted to the inner wall of the sealing groove.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] In this invention, the mounting rod on the second connecting part is first aligned with the mounting hole on the first connecting part, and then inserted. During the insertion of the mounting rod, it will contact and press the positioning rod. The pressed positioning rod will move outward, thereby driving the connecting plate to move to the left and right sides. When the connecting plate moves, it will cause the spring to stretch. As the mounting rod continues to be inserted, it will move the positioning hole on its outer wall to the position of the positioning rod. At this time, the spring will rebound and push the positioning rod to insert and engage in the inner wall of the positioning hole, thereby completing the splicing and installation between the first connecting part and the second connecting part. This eliminates the installation process and can be installed without the use of tools.

[0017] In this invention, during the process of connecting and installing the first connecting part and the second connecting part, the first sealing ring on the first connecting part will be inserted into the interior of the second connecting part, thereby providing a tight seal at the connection between the first connecting part and the second connecting part. At the same time, the second sealing ring on the second connecting part will be inserted into the sealing groove on the first connecting part, thereby further improving the sealing effect at the connection between the first connecting part and the second connecting part based on the first sealing ring.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figures 1 to 4 As shown, a sealing device for the connection between upper and lower sections of a flue includes a first connecting part 1 and a second connecting part 2 disposed on one side of the first connecting part 1. A disassembly / assembly mechanism 31 is provided on both the first connecting part 1 and the second connecting part 2. A sealing mechanism 32 is provided on the disassembly / assembly mechanism 31. An installation hole 311 is formed on the outer wall of one side of the first connecting part 1. An installation rod 312 is fixedly connected to the outer wall of one side of the second connecting part 2. A positioning hole 313 is formed on the outer wall of the installation rod 312. A through hole is formed on the outer wall of the first connecting part 1, and a positioning rod 314 is slidably disposed inside the through hole. The positioning rod 314 is located away from the outer wall of the first connecting part 1. A connecting plate 315 is fixedly connected to the end of the first connecting part 1. A spring 316 is fixedly connected to the side of the connecting plate 315 near the outer wall of the first connecting part 1. The end of the spring 316 away from the outer wall of the connecting plate 315 is fixedly connected to the outer wall of the first connecting part 1. A force-bearing plate 317 is fixedly connected to the outer wall of the connecting plate 315. A sliding hole is opened at the top of the first connecting part 1. A sliding rod 318 is slidably arranged on the inner wall of the sliding hole. A supporting connecting plate 319 is fixedly connected to the outer wall of the sliding rod 318. A top block 3110 is fixedly connected to the end of the supporting connecting plate 319 away from the outer wall of the sliding rod 318. A limit plate 3111 is fixedly connected to the end of the sliding rod 318 away from the supporting connecting plate 319.

[0027] Furthermore, there are four mounting rods 312, which are symmetrically distributed in pairs on one end of the outer wall of the second connecting part 2. This can stabilize the four corners of the first connecting part 1 and the second connecting part 2, thereby improving the stability of the splicing and installation of the two.

[0028] Furthermore, the outer wall of the mounting rod 312 fits snugly against the inner wall of the mounting hole 311, and the inner wall of the positioning hole 313 fits snugly against the outer wall of the positioning rod 314. This ensures the stability of the mounting rod 312 after insertion and installation, and also ensures the stability of the positioning rod 314 after snapping in.

[0029] Furthermore, the outer wall of the force plate 317 away from the connecting plate 315 is provided with an inclined surface, and the outer wall of the top block 3110 fits in close contact with the inclined surface. This ensures that the top block 3110 can squeeze and move the inclined surface of the force plate 317 during downward movement, so as to facilitate disassembly.

[0030] The sealing mechanism 32 includes a first sealing ring 321 fixedly connected to the outer wall of one end of the first connecting part 1, a second sealing ring 323 fixedly connected to the outer wall of one end of the second connecting part 2, and a sealing groove 322 formed on the outer wall of one end of the first connecting part 1.

[0031] Furthermore, the outer wall of the first sealing ring 321 fits snugly against the inner wall of the second connecting part 2, thereby ensuring a tight fit between the first sealing ring 321 and the inner wall of the second connecting part 2, thus improving its sealing effect.

[0032] Furthermore, the outer wall of the second sealing ring 323 fits snugly against the inner wall of the sealing groove 322, thus ensuring a tight fit between the outer wall of the second sealing ring 323 and the inner wall of the sealing groove 322 after installation, thereby further improving the sealing effect.

[0033] The implementation principle of a sealing device for the connection between the upper and lower sections of a flue in this embodiment is as follows: When it is necessary to install and connect the first connecting part 1 and the second connecting part 2, firstly, align the mounting rod 312 on the second connecting part 2 with the mounting hole 311 on the first connecting part 1, and then insert it into it. During the insertion process of the mounting rod 312, it will contact and press the positioning rod 314. The pressed positioning rod 314 will move outward, thereby driving the connecting plate 315 to move to the left and right sides. When the connecting plate 315 moves, it will drive the spring 316 to stretch. As the mounting rod 312 continues to be inserted, it drives the positioning hole 313 on its outer wall to move to the position of the positioning rod 314. When the spring 316 returns to its original position, it pushes the positioning rod 314 to insert into the inner wall of the positioning hole 313, thereby completing the splicing and installation between the first connecting part 1 and the second connecting part 2. When disassembly is required, simply push the slide rod 318 downward to move it, thereby driving the support plate 319 downward. The movement of the support plate 319 will drive the top block 3110 downward. When the top block 3110 moves downward, it will apply force to the left and right force plates 317, pushing the force plates 317 to move. In this way, the movement of the force plates 317 will drive the positioning rods 314 on both sides to disengage from the interior of the positioning hole 313, thereby contacting the limit of the mounting rod 312. Then the mounting rod 312 can be removed from the mounting hole 311.

[0034] During the process of connecting and installing the first connecting part 1 and the second connecting part 2, the first sealing ring 321 on the first connecting part 1 will be inserted into the interior of the second connecting part 2, thereby sealing the connection between the first connecting part 1 and the second connecting part 2. At the same time, the second sealing ring 323 on the second connecting part 2 will be inserted into the sealing groove 322 on the first connecting part 1, thereby further improving the sealing effect at the connection between the first connecting part 1 and the second connecting part 2 based on the first sealing ring 321.
