Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, and in particular to a connection device for installing heating and ventilation pipelines. Background Technology

[0002] Heating and ventilation ducts are metal or composite pipes used in ventilation and air conditioning projects for industrial and civil buildings. In existing heating and ventilation system pipe installation projects, flanges are usually used in conjunction with bolts or direct socket welding to connect two pipes.

[0003] Traditional installation methods are generally cumbersome and inefficient, especially when there is a certain deviation in the pipe axis or the installation space is limited. Adjusting the alignment is difficult, time-consuming, and labor-intensive. More importantly, existing connection methods are highly dependent on installation accuracy. If the sealing gasket is not installed correctly or the welding is not tight, air and heat leakage can easily occur at the joint, reducing system energy efficiency, causing heat loss, and affecting ventilation. In addition, the vibration and thermal expansion and contraction stress of the pipeline system are directly transmitted to the connection and fixed structure. The lack of an effective buffer mechanism can easily lead to loose connections, bolt fatigue, or even interface deformation and cracking, threatening the long-term stability and safety of the system. At the same time, once the position and angle of the fixed installation point are determined, it is difficult to adjust flexibly, making it difficult to adapt to the needs of pipeline layout in different directions in complex building structures or the requirements of possible later line changes, which greatly limits the flexibility and adaptability of engineering design. Summary of the Invention

[0004] To overcome the technical defects of the existing technology, this utility model provides a heating and ventilation duct installation and docking device, which has the advantages of convenient installation, good sealing effect and adjustable installation angle.

[0005] The technical solution adopted by this utility model is as follows: it includes a first ventilation duct and a second ventilation duct for heating and ventilation, a docking assembly is provided between the first ventilation duct and the second ventilation duct, a fixing bracket is fixed at the top of the first ventilation duct, the bottom of the first ventilation duct, the top of the second ventilation duct and the bottom of the second ventilation duct, bolts are installed between the fixing bracket and the docking assembly, and an adjustable angle mounting assembly is fixedly installed on the top of the docking assembly.

[0006] Preferably, in order to connect the first ventilation duct and the second ventilation duct, the connection assembly includes a connecting frame with slots symmetrically provided on both sides of the connecting frame. A sealing ring is fixedly installed inside each of the two slots, and one end of the first ventilation duct and one end of the second ventilation duct are respectively inserted into the two slots.

[0007] Preferably, in order to heat and reheat the circulating air, a heating rod for reheating is fixedly installed inside the connecting frame, and a heating wire is provided inside the heating rod.

[0008] Preferably, in order to enhance the stability of the connecting frame, a fixing block is fixed at the top and bottom of the connecting frame, and a mounting groove is provided on both sides of the fixing block. A spring is fixedly installed inside the mounting groove, and a connecting column is fixed at the other end of the spring. Both the spring and the connecting column are located inside the mounting groove.

[0009] Preferably, in order to fix the connecting frame and the fixing frame, an L-shaped mounting bracket is fixed to the other end of the connecting column, and the other end of the L-shaped mounting bracket is snapped into the inside of the fixing frame.

[0010] Preferably, in order to adjust the installation angle of the connecting frame, the adjustable angle mounting assembly includes a base with a rotating groove at the top, the bottom of the base being fixedly installed on the top of the connecting frame, and a universal ball being rotatably disposed inside the rotating groove.

[0011] Preferably, in order to flexibly adjust the extension length of the screw, a threaded cylinder with an internal threaded groove is fixed to the outside of the universal ball, the threaded cylinder is located above the base, and a screw with an external thread is installed inside the threaded cylinder, and the threaded cylinder and the screw are threadedly connected.

[0012] Preferably, in order to drive the screw to rotate so that the angle of the top plate can be adjusted, a rotating block is fixed on the outside of the screw thread, and the top plate is rotatably mounted on the other end of the screw.

[0013] The beneficial effects of this utility model are as follows: by setting a slot-type connecting frame with a built-in sealing ring as a docking component, the insertion and installation of the first and second ventilation ducts are simple and quick, and the airtightness of the docking point is ensured, effectively reducing air and heat leakage.

This allows the device to easily adapt to complex installation spaces and connection requirements in different directions, greatly improving installation efficiency and system adaptability.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5 As shown, this embodiment provides a heating and ventilation duct installation and docking device, including a first ventilation duct 1 and a second ventilation duct 2 for heating and ventilation. A docking component 3 is provided between the first ventilation duct 1 and the second ventilation duct 2. Fixing brackets 5 are fixed at the top and bottom of the first ventilation duct 1, the top and bottom of the second ventilation duct 2, and the docking component 3. Bolts 6 are installed between the fixing brackets 5 and the docking component 3, which improves the stability between the first ventilation duct 1, the second ventilation duct 2 and the docking component 3. An adjustable angle installation component 4 is fixedly installed on the top of the docking component 3.

[0022] In actual use, the operator first inserts one end of the first ventilation duct 1 and one end of the second ventilation duct 2 into the docking assembly 3, which enhances the sealing of the duct connection and reduces air and heat leakage. Then, the operator uses bolts 6 to fix the fixing frame 5 and the docking assembly 3, thereby completing the installation and docking of the first ventilation duct 1 and the second ventilation duct 2. When it is necessary to adjust the installation angle of the first ventilation duct 1 and the second ventilation duct 2, the adjustable angle installation assembly 4 can be adjusted, and the adjustable angle installation assembly 4 can be fixed to the wall using expansion screws. This allows the device to flexibly adapt to different installation angles and height requirements, further improving the installation efficiency and flexibility between ventilation ducts.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 3As shown, the docking assembly 3 includes a connecting frame 301. Slots 302 are symmetrically opened on both sides of the connecting frame 301. A sealing ring 303 is fixedly installed inside each of the two slots 302. One end of the first ventilation duct 1 and one end of the second ventilation duct 2 are respectively inserted into the two slots 302. A heating rod 304 for reheating is fixedly installed inside the connecting frame 301. A heating wire is provided inside the heating rod 304, which can heat and reheat the circulating air, thereby improving the heating effect. Fixing blocks 305 are fixed at the top and bottom of the connecting frame 301. Mounting grooves 306 are opened on both sides of the fixing blocks 305. A spring 307 is fixedly installed inside the mounting grooves 306. A connecting post 308 is fixed at the other end of the spring 307. The spring 307 and the connecting post 308 are both located inside the mounting grooves 306. An L-shaped mounting bracket 309 is fixed at the other end of the connecting post 308. The other end of the L-shaped mounting bracket 309 is snapped into the inside of the fixing frame 5.

[0024] In use, the operator first inserts one end of the first ventilation duct 1 and the second ventilation duct 2 into the slots 302 on both sides of the connecting frame 301. The sealing ring 303 inside the slot 302 can effectively enhance the sealing of the pipe connection and reduce the occurrence of air and heat leakage. The heating wire inside the heating rod 304 can heat and reheat the circulating air, improving the heating and ventilation effect. At the same time, the fixing blocks 305 at the top and bottom of the connecting frame 301 are connected to the L-shaped mounting frame 309 through the spring 307 and the connecting column 308. The other end of the L-shaped mounting frame 309 is snapped into the fixing frame 5. The setting of the spring 307 enhances the stability of the connecting frame 301, making the device more stable and reliable during use, and enabling the ventilation ducts to be quickly connected and assembled.

[0025] As a technical optimization solution of this utility model, specifically as follows: Figures 4-5 As shown, the adjustable angle mounting assembly 4 includes a base 401 with a rotating groove on the top. The bottom of the base 401 is fixedly mounted on the top of the connecting frame 301. A universal ball 402 is rotatably arranged inside the rotating groove. A threaded cylinder 403 with a threaded groove inside is fixed on the outside of the universal ball 402. The threaded cylinder 403 is located above the base 401. A screw 404 with threads on the outside is installed inside the threaded cylinder 403. The threaded cylinder 403 and the screw 404 are threaded together. A rotating block 405 is fixed on the outside of the threads to facilitate adjustment of the length of the screw 404 extending out of the threaded cylinder 403. A top plate 406 is rotatably mounted on the other end of the screw 404.

[0026] In use, the operator rotates the rotating block 405 to drive the screw 404 to rotate inside the threaded cylinder 403. Because the threaded cylinder 403 and the screw 404 are threadedly connected, the extension length of the screw 404 changes with the rotation of the rotating block 405. The operator can flexibly adjust the extension length of the screw 404 according to actual installation requirements, thereby achieving precise control of the height of the top plate 406. After the height of the top plate 406 is adjusted, the operator can use expansion screws to fix the top plate 406 to the wall. Since the top plate 406 is connected to the threaded cylinder 403 via the screw 404, and the threaded cylinder 403 is fixedly installed on the outside of the universal ball 402, the universal ball 402 can rotate flexibly at multiple angles within the rotating groove of the base 401. Therefore, the top plate 406 can achieve flexible adjustment at multiple angles as the universal ball 402 rotates, allowing the device to flexibly adapt to different installation angles and height requirements, further improving the installation efficiency and flexibility of the ventilation duct.
