Description

Technical Field

[0001] This utility model relates to the field of ventilation duct installation, and in particular to a ventilation duct installation device for buildings. Background Technology

[0002] Building ventilation ducts are piping systems used to transport air, gases, and dust. They are usually made of metal or plastic and are used to distribute air and gases in buildings or other facilities. Ducts are usually installed inside the ceiling to hide the decorative piping. By arranging ducts properly, an aesthetically pleasing and neat effect can be achieved.

[0003] According to Chinese patent disclosure (publication number: CN216896095U), a ventilation duct installation method for building engineering is described. The first ventilation duct and the second ventilation duct are respectively hoisted below the top plate by two hoisting mechanisms. The auxiliary support provided by the hoisting mechanisms to the ventilation ducts makes the connection between the first ventilation duct and the second ventilation duct simpler.

[0004] In the above technical solution, the hoisting mechanism is used to support the installation of ventilation ducts. However, the ducts need to be moved during installation to adjust the alignment of the connecting surfaces. The lack of a guiding function for the movement of the ducts leads to greater friction between the ducts and the contact surfaces, which reduces the efficiency of duct installation. Therefore, a building ventilation duct installation device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a building ventilation duct installation device, which aims to improve the problem that the existing building ventilation duct installation devices lack the function of guiding the movement of the duct during installation, thus reducing the ease of installation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a duct installation device for building ventilation, comprising an installation frame, an embedded groove on the surface of the installation frame, a threaded rod threadedly connected to the inner wall of the installation frame, a knob fixedly connected to the bottom end of the threaded rod, a limit rod slidably connected to the inner wall of the installation frame, a support plate rotatably connected to the top end of the threaded rod, a slot on the top of the support plate, a bidirectional lead screw rotatably connected to the inner wall of the support plate, a sliding rod fixedly connected to the inner wall of the support plate, a positioning plate threadedly connected to the outer wall of the bidirectional lead screw, a telescopic rod fixedly connected to the top of the installation frame, a telescopic spring sleeved on the outer wall of the telescopic rod, a fixing frame fixedly connected to the top end of the telescopic spring, and a guide wheel rotatably connected to the inner wall of the fixing frame.

[0007] As a further description of the above technical solution: The inner wall of the embedding groove is adapted to the outer wall of the support plate.

[0008] As a further description of the above technical solution: The bottom of the support plate is fixedly connected to the top of the limiting rod.

[0009] As a further description of the above technical solution: The inner wall of the positioning plate is slidably connected to the outer wall of the slide rod.

[0010] As a further description of the above technical solution: The upper surface of the support plate is provided with an installation groove, and an airbag is fixedly connected to the inner wall of the installation groove.

[0011] As a further description of the above technical solution: An air pump is fixedly connected to the inner wall of the support plate, an inflation tube is fixedly connected to the port of the air pump, a one-way valve is provided on the surface of the inflation tube, a fixing spring is fixedly connected to the inner wall of the airbag, and an anti-slip sticker is fixedly connected to the top of the airbag.

[0012] As a further description of the above technical solution: The outer wall of the inflation tube is fixedly connected to the inner wall of the airbag, and the inflation tube extends into the interior of the airbag.

[0013] As a further description of the above technical solution: The one-way valve is located inside the airbag, the top end of the fixing spring is fixedly connected to the top of the inner wall of the airbag, and the bottom end of the fixing spring is fixedly connected to the bottom of the inner wall of the airbag.

[0014] This utility model has the following beneficial effects: 1. In this utility model, guide wheels are provided to guide and reduce resistance when the pipe is pushed into the mounting frame. The cooperation of telescopic rod and telescopic spring helps the guide wheels to reduce impact. The knob controls the threaded rod and the limit rod to lift the support plate onto the pipe. The two-way screw rod and slide rod allow the two sets of positioning plates to fit against both sides of the pipe, so that the pipe can be fixed on all four sides with the top of the space during installation to ensure the stability of the installation.

[0015] 2. In this utility model, an air pump is provided to inject air into the airbag through an inflation tube. Combined with the elasticity of the fixed spring and the friction of the anti-slip pad, the airbag can reduce the vibration force generated when the pipeline transports gas, thus ensuring the stability of the pipeline.

Detailed Implementation

[0018] 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.

[0019] Reference Figures 1-3This utility model provides an embodiment of a building ventilation duct installation device, including a mounting frame 1. The mounting frame 1 can be fixed to the top of a space by external screws. An embedding groove 2 is formed on the surface of the mounting frame 1. A threaded rod 4 is threadedly connected to the inner wall of the mounting frame 1. A knob 3 is fixedly connected to the bottom end of the threaded rod 4. A limit rod 5 is slidably connected to the inner wall of the mounting frame 1. A support plate 6 is rotatably connected to the top end of the threaded rod 4. A slot 7 is formed on the top of the support plate 6. Four sets of slots 7 are arranged in a rectangular array with the center point of the support plate 6 as the axis of symmetry. The slots 7 facilitate the installation of a bidirectional lead screw 8 and a sliding rod 9. A bidirectional lead screw 8 is rotatably connected to the inner wall of the support plate 6. A sliding rod 9 is fixedly connected to the inner wall of the support plate 6, and a positioning plate 10 is threadedly connected to the outer wall of the double-acting screw 8. A telescopic rod 13 is fixedly connected to the top of the mounting frame 1. A telescopic spring 14 is sleeved on the outer wall of the telescopic rod 13. A fixing frame 15 is fixedly connected to the top of the telescopic spring 14. A guide wheel 16 is rotatably connected to the inner wall of the fixing frame 15. There are four sets of telescopic rods 13, telescopic springs 14, fixing frames 15 and guide wheels 16. The four sets of telescopic rods 13, telescopic springs 14, fixing frames 15 and guide wheels 16 are arranged in a rectangular array with the center point of the mounting frame 1 as the axis of symmetry. The guide wheel 16 can contact the bottom of the pipe. When the pipe is pushed into the mounting frame 1, the guide wheel 16 will rotate to provide movement guidance.

[0020] Reference Figures 3-5 The inner wall of the embedded groove 2 is adapted to the outer wall of the support plate 6. When the support plate 6 is completely inside the embedded groove 2, the top of the guide wheel 16 is higher than the top of the support plate 6. The bottom of the support plate 6 is fixedly connected to the top of the limiting rod 5. The limiting rod 5 plays a limiting role during the lifting and lowering of the support plate 6. The inner wall of the positioning plate 10 is slidably connected to the outer wall of the slide rod 9. The upper surface of the support plate 6 is provided with an installation groove 11. An airbag 12 is fixedly connected to the inner wall of the installation groove 11. The airbag 12 can contact the bottom of the pipe and increase the buffering force between the pipe and the support plate 6.

[0021] Reference Figures 3-5An air pump 17 is fixedly connected to the inner wall of the support plate 6. The air pump 17 can inflate the airbag 12 with air through the inflation tube 18. The inflation tube 18 is fixedly connected to the port of the air pump 17. The outer wall of the inflation tube 18 is fixedly connected to the inner wall of the airbag 12. The inflation tube 18 extends into the interior of the airbag 12. A one-way valve 19 is provided on the surface of the inflation tube 18. The one-way valve 19 controls the airflow direction of the inflation tube 18. The one-way valve 19 is a push-button switch. The airbag 12 is flexible. The material allows direct contact between the one-way valve 19 and the outside of the airbag 12. The one-way valve 19 is located inside the airbag 12. A fixing spring 20 is fixedly connected to the inner wall of the airbag 12. The top end of the fixing spring 20 is fixedly connected to the top of the inner wall of the airbag 12, and the bottom end of the fixing spring 20 is fixedly connected to the bottom of the inner wall of the airbag 12. An anti-slip sticker 21 is fixedly connected to the top of the airbag 12. The anti-slip sticker 21 increases the friction between the airbag 12 and the pipe, ensuring the tightness of their contact.

[0022] Working principle: After the mounting bracket 1 is fixed to the top of the space, the pipe is pushed in through the opening of the mounting bracket 1. The pipe will contact the guide wheel 16. The guide wheel 16 will rotate as the pipe moves in position, providing guidance for the movement of the pipe and avoiding large friction between the pipe and the support plate 6 during the displacement process. At the same time, the elasticity of the telescopic rod 13 and the telescopic spring 14 can provide a certain impact reduction for the guide wheel 16. After the pipe position is moved, manually rotate the knob 3 in the forward direction. The threaded rod 4 and the limit rod 5 will lift the support plate 6. After the support plate 6 contacts the bottom of the pipe, continue to rotate the knob 3 until the top of the pipe is in contact with the top of the space.

[0023] The two-way lead screw 8 is manually rotated, and the sliding rod 9 limits the movement of the two sets of positioning plates 10, which gradually bring them closer together to fix both sides of the pipe. The air pump 17 is manually pumped, and air is injected into the air bag 12, causing it to gradually expand. With the elasticity of the fixing spring 20, the vibration caused by the impact of gas being transported during use is reduced. The two sets of positioning plates 10 and the support plate 6 work together to fix the pipe on all four sides, improving the stability and ease of installation.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
