Description
Technical Field
[0001] This utility model relates to the field of flue splicing technology, and in particular to a flue splicing device for high-rise residential buildings. Background Technology
[0002] In modern residential buildings, flue systems are an indispensable infrastructure in areas such as kitchens and bathrooms. They are mainly used to exhaust fumes and exhaust gases and maintain indoor air circulation. For multi-story or high-rise buildings, flues are usually designed in sections, which are spliced together layer by layer through multiple flue pipes. This "layered" structure requires the splicing device to have reliable sealing and convenient installation and maintenance performance in order to meet the maintenance needs during residential construction, decoration and long-term use.
[0003] Currently, traditional methods for splicing residential flues mainly involve welding, bolt fixing, or cement mortar pouring. These methods suffer from low assembly efficiency, difficulty in disassembly and maintenance, and insufficient standardization and sealing. Welding requires professional welders and poses a risk of open flame, bolt fixing can easily damage the seal, and cement pouring has a long construction cycle. When problems such as smoke leakage or blockage occur in the flue, traditional fixing methods can lead to cracking and deformation of the flue pipe wall during disassembly, resulting in extremely high maintenance costs. Therefore, a high-rise residential flue splicing device is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a high-rise residential building flue splicing device to solve the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-rise residential building flue splicing device includes a first flue and a second flue. A positioning component is provided between the first and second flues. Fixing plates are fixedly installed on both sides of the second flue. Both fixing plates are L-shaped, and a set of slots is opened on the opposite sides of the two fixing plates. Each set of slots has two slots. A fixing box is fixedly installed on one side of the first flue. A synchronous winding component is provided inside the fixing box. A set of springs is fixedly installed on both sides of the fixing box. Each set of springs has two springs. A connecting plate is fixedly connected to the ends of the two sets of springs that are far apart from each other. A set of inserts is fixedly installed on the opposite sides of the two connecting plates. Each set of inserts has two inserts. The other ends of the two sets of inserts are respectively inserted into the two sets of slots. A guide component is provided on one side of the first flue.
[0007] Preferably, the positioning component includes a positioning groove on the top side of the first flue, a positioning plate inserted into the positioning groove, and the top side of the positioning plate being fixedly connected to the bottom side of the second flue.
[0008] Preferably, the synchronous winding assembly includes a circular hole on one side of the fixed box, a rotating rod inside the circular hole, one end of the rotating rod being rotatably connected to the inner wall of one side of the fixed box, a first gear being fixedly sleeved on the outer side of the rotating rod, a rotating column being provided inside the fixed box, both ends of the rotating column being rotatably connected to the inner walls of both sides of the fixed box, a second gear being fixedly sleeved on the outer side of the rotating column, and the second gear meshing with the first gear.
[0009] Preferably, a first winding wheel and a second winding wheel are fixedly sleeved on the outer sides of the rotating rod and the rotating column, respectively. Ropes are fixedly wound on the outer sides of both the first winding wheel and the second winding wheel. Through holes are opened on both sides of the fixing box. The other ends of the two ropes pass through the two through holes and are fixedly connected to the opposite sides of the two connecting plates.
[0010] Preferably, a handwheel is fixedly connected to the other end of the rotating rod. A threaded hole and a threaded groove are respectively opened on one side of the handwheel and the fixed box. A threaded post is threadedly installed in the threaded hole, and the other end of the threaded post is threadedly installed into the threaded groove that is aligned with the threaded hole.
[0011] Preferably, the guide assembly includes a connecting frame fixedly installed on one side of the first flue, the connecting frame being U-shaped, a guide rod fixedly installed inside the connecting frame, and one side of each of the two connecting plates being slidably sleeved on the guide rod.
[0012] Preferably, a set of telescopic rods is fixedly installed on both sides of the fixing box, and there are two telescopic rods in each set. The ends of the two sets of telescopic rods that are far apart from each other are fixedly connected to the opposite surfaces of the two connecting plates, and the two sets of telescopic rods are located in the two sets of springs respectively.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By rotating the handwheel, the rotating rod is driven to rotate. Through the meshing transmission of the first and second gears, the first and second winding wheels synchronously wind up the rope, pulling the connecting plate to move. Compared with the traditional welding and bolt fixing methods, no professional tools or complicated operations are required, and a single person can quickly complete the splicing. At the same time, the cooperation between the positioning plate and the positioning groove in the positioning component can quickly achieve the initial positioning of the flue, reducing the splicing calibration time. In addition, the guide rod of the guide component ensures the smooth sliding of the connecting plate, and the telescopic rod prevents the spring from twisting, ensuring that the plug is accurately inserted into the slot, further improving the assembly efficiency.
[0015] 2. By turning the handwheel clockwise, the insert can be easily pulled out of the slot under the contraction of the spring, releasing the fixed connection of the flue. Disassembly can be completed without damaging the structure. Compared with the traditional method, it avoids the problem of flue pipe wall cracking and deformation during disassembly. The threaded column limits and fixes the handwheel, which can prevent the insert from loosening due to vibration of the gear during use, ensuring connection stability. When there are problems such as smoke leakage or blockage in the flue, the corresponding part can be quickly disassembled for inspection or replacement, reducing maintenance costs and difficulty, and improving the maintainability of the flue system.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Reference Figure 1-4A high-rise residential building flue splicing device includes a first flue 1 and a second flue 2. A positioning component is installed between the first flue 1 and the second flue 2. Fixing plates 5 are fixedly installed on both sides of the second flue 2. Both fixing plates 5 are L-shaped. A set of slots 6 is opened on the opposite side of the two fixing plates 5. There are two slots 6 in each set. A fixing box 7 is fixedly installed on one side of the first flue 1. A synchronous winding component is installed inside the fixing box 7. A set of springs 15 is fixedly installed on both sides of the fixing box 7. There are two springs 15 in each set. A connecting plate 16 is fixedly connected to the ends of the two sets of springs 15 that are far apart from each other. A set of inserts 17 is fixedly installed on the opposite sides of the two connecting plates 16. There are two insert blocks 17. The other ends of the two sets of insert blocks 17 are respectively inserted into two sets of slots 6. A guide assembly is provided on one side of the first flue 1. The synchronous winding assembly includes a circular hole on one side of the fixed box 7. A rotating rod 8 is provided in the circular hole. One end of the rotating rod 8 is rotatably connected to the inner wall of one side of the fixed box 7. A first gear 9 is fixedly sleeved on the outer side of the rotating rod 8. A rotating column 10 is provided inside the fixed box 7. Both ends of the rotating column 10 are rotatably connected to the inner walls of both sides of the fixed box 7. A second gear 11 is fixedly sleeved on the outer side of the rotating column 10. The second gear 11 meshes with the first gear 9. A first winding wheel 12 and a second winding wheel are fixedly sleeved on the outer sides of the rotating rod 8 and the rotating column 10, respectively. 13. Ropes 14 are fixedly wound on the outer sides of both the first and second take-up reels 12 and 13. Through holes are provided on both sides of the fixing box 7. The other ends of the two ropes 14 pass through the two through holes and are fixedly connected to the opposite sides of the two connecting plates 16. A first gear 9 is fixedly sleeved on the outer side of the rotating rod 8, and the first gear 9 meshes with the second gear 11. Therefore, under the meshing transmission of the first gear 9, the second gear 11 will rotate in the opposite direction, causing the first and second take-up reels 12 and 13, which are fixedly sleeved on the outer sides of the rotating rod 8 and the rotating column 10 respectively, to rotate synchronously relative to each other. This causes the ropes 14 fixedly wound on the outer sides of both the first and second take-up reels 12 and 13 to begin winding. The two ropes 14 are wound together, and because the other ends of the two ropes 14 are fixedly connected to the opposite sides of the two connecting plates 16, the two ropes 14 will pull the two connecting plates 16 closer to each other during the synchronous winding process. When the two connecting plates 16 are close to each other, they will squeeze a set of springs 15 connected to them. After the two sets of connecting plates 16 gradually approach each other, the second flue 2 is spliced by the positioning plate 4. After splicing, the two sets of inserts 17 will be aligned with the two sets of slots 6. At this time, the handwheel 19 is turned counterclockwise, and the two sets of connecting plates 16 will move away from each other under the reset of the two sets of springs 15, so that the two sets of inserts 17 are inserted into the two sets of slots 6 respectively, thereby realizing the fixed connection between the first flue 1 and the second flue 2.
[0023] Specifically, the positioning component includes a positioning groove 3 on the top side of the first flue 1, a positioning plate 4 inserted into the positioning groove 3, and the top side of the positioning plate 4 fixedly connected to the bottom side of the second flue 2. By setting the positioning plate 4, when assembling the first flue 1 and the second flue 2, the positioning plate 4 fixedly connected to the bottom side of the second flue 2 is aligned with the positioning groove 3 on the top side of the first flue 1. After alignment, the positioning plate 4 is inserted into the positioning groove 3 to complete the initial splicing of the flue. When the positioning plate 4 is inserted into the positioning groove 3, it can also play a sealing role, thereby preventing smoke from drifting out along the gap between the first flue 1 and the second flue 2.
[0024] Specifically, a handwheel 19 is fixedly connected to the other end of the rotating rod 8. Threaded holes and threaded grooves are respectively opened on one side of the handwheel 19 and the fixed box 7. A threaded post 20 is threadedly installed in the threaded hole, and the other end of the threaded post 20 is threaded into the threaded groove that is aligned with the threaded hole. By setting the threaded post 20, when the two sets of inserts 17 are respectively inserted into the two sets of slots 6, the threaded hole of the handwheel 19 will be aligned with the threaded groove on one side of the fixed box 7. At this time, the threaded post 20 is threaded into the threaded hole, and then the threaded post 20 is rotated to thread the other end of the threaded post 20 into the threaded groove that is aligned with the threaded hole. This achieves a fixed connection between the handwheel 19 and the fixed box 7, preventing the two gears from rotating due to slight vibrations generated by the flue. By limiting the handwheel 19, it is also possible to ensure that the two sets of inserts 17 are always inserted into the two sets of slots 6.
[0025] Specifically, the guide assembly includes a connecting frame 21 fixedly installed on one side of the first flue 1. The connecting frame 21 is U-shaped, and a guide rod 22 is fixedly installed inside the connecting frame 21. One side of each of the two connecting plates 16 is slidably sleeved on the guide rod 22. By setting the guide rod 22, the other side of the two connecting plates 16 will not shake or shift, thereby ensuring that the two sets of inserts 17 can be accurately inserted into the two sets of slots 6.
[0026] Specifically, a set of telescopic rods 18 is fixedly installed on both sides of the fixed box 7. There are two telescopic rods 18 in each set. The ends of the two sets of telescopic rods 18 that are far apart from each other are fixedly connected to the opposite surfaces of the two connecting plates 16. The two sets of telescopic rods 18 are located in the two sets of springs 15. By setting two sets of telescopic rods 18, the two sets of telescopic rods 18 can play a limiting role to prevent the springs 15 from twisting. At the same time, the two sets of telescopic rods 18 can also play a limiting and guiding role when the connecting plates 16 move, so that they can move smoothly.
[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.
[0028] In use: When splicing the flue, first unscrew the threaded post 20 of the fixed handwheel 19 to release its constraint. Then, turn the handwheel 19 clockwise. The rotation of the handwheel 19 will drive the rotating rod 8 to rotate synchronously. Since the first gear 9 is fixedly sleeved on the outside of the rotating rod 8, and the first gear 9 meshes with the second gear 11, the second gear 11 will rotate in the opposite direction under the gear transmission principle. In this way, the first winding wheel 12 and the second winding wheel 13, which are fixedly sleeved on the outside of the rotating rod 8 and the rotating post 10 respectively, will rotate synchronously relative to each other, and begin to wind up the rope 14 wrapped around its outside. Since the other ends of these two ropes 14 are fixedly connected to two connecting plates 16 respectively, as the ropes 14 are wound up, they will pull the two connecting plates 16 closer to each other. During this process, a set of... Spring 15 will be compressed and stored. As the two sets of connecting plates 16 gradually approach each other, the positioning plate 4, which is fixedly connected to the bottom side of the second flue 2, is precisely aligned with the positioning groove 3 opened on the top side of the first flue 1. After the alignment is correct, the positioning plate 4 is inserted into the positioning groove 3 to complete the initial splicing of the flue. When the bottom side of the second flue 2 is completely in contact with the top side of the first flue 1, the two sets of inserts 17 will also accurately correspond to the two sets of slots 6. At this time, the handwheel 19 is turned counterclockwise. Under the reset action of spring 15, the two sets of connecting plates 16 move away from each other, pushing the two sets of inserts 17 into the two sets of slots 6 respectively, realizing a stable connection between the first flue 1 and the second flue 2. After the insertion is completed, the threaded post 20 is passed through the handwheel 19 again and fixed to ensure that the handwheel 19 will not rotate at will, thus ensuring the stability of the flue splicing structure.
