Description

Technical Field

[0001] This utility model belongs to the field of ventilation duct technology, specifically referring to a structure that facilitates the installation of ventilation ducts. Background Technology

[0002] In the construction of building ventilation systems, the installation of ventilation ducts is a crucial step, as its quality and ease of installation directly affect the performance and effectiveness of the entire ventilation system.

[0003] Traditional ventilation duct installation structures use welding or a large number of bolts for fixing. This connection method is slow to install, and the bolts need to be completely removed during disassembly, which is not conducive to maintenance. Furthermore, due to the diversity of building structures and spatial layouts, ventilation ducts in different locations need to be adjusted in height according to the actual situation during installation to ensure that the ducts can be smoothly connected to form a complete ventilation system. Traditional installation structures often make it difficult to achieve height adjustment of ventilation ducts. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional ventilation duct installation structures use welding or a large number of bolts for fixing. This connection method is slow to install, and due to the diversity of building structures and spatial layouts, it is difficult to adjust the height of the ventilation duct.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a structure for easy installation of ventilation ducts, including a ventilation duct, a support bracket at the bottom of the ventilation duct, a bending plate at the top of the support bracket, a slot 1 on the bending plate, a fixing plate detachably connected to the top of the support bracket, and slots 2 corresponding to slot 1 at both ends of the fixing plate. A stud is rotatably connected to slot 2 via a shaft, the bottom of the stud is engaged in slot 1, and a nut is threadedly connected to the bottom of the stud.

[0006] Preferably, the support bracket is U-shaped, and two sets of support brackets are arranged in parallel. The fixing plates are arranged correspondingly to the support brackets, and a connecting plate is provided between the two sets of fixing plates.

[0007] Preferably, the connecting plate is provided with a telescopic component, the top end of the telescopic component is provided with a mounting plate, and the mounting plate is provided with mounting holes.

[0008] Preferably, the telescopic component includes a fixed cylinder, a sliding cylinder, and a screw. The bottom end of the fixed cylinder is fixed to the connecting plate, the sliding cylinder is slidably sleeved on the fixed cylinder, and a baffle is provided on the inner side wall of the top of the sliding cylinder. The screw is threadedly connected to the fixed cylinder, and its top end rotates through the baffle and is rotatably connected to the inner top wall of the sliding cylinder.

[0009] Preferably, the inner wall of the slide cylinder is rotatably provided with a driving bevel gear, the screw is fixedly fitted with a driven bevel gear, the driven bevel gear meshes with the driving bevel gear, the driven bevel gear is located above the baffle, and the side wall of the slide cylinder is provided with a handle that rotates through the side wall and is connected to the driving bevel gear.

[0010] Preferably, a number of ribs are provided between the bottom end of the fixed cylinder and the connecting plate.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. This structure features a bending plate, a fixing plate, studs, and nuts at the top of the support bracket. By inserting the bottom of the stud into the first slot of the bending plate and allowing it to pass through the second slot of the fixing plate, and then securing it with the nut, the ventilation duct and its support bracket can be firmly connected during installation. When it is necessary to disassemble a section of the ventilation duct, simply drag the section of ventilation duct from the bottom, loosen the nut, and unscrew the stud from the second slot of the fixing plate to easily remove the section of ventilation duct and support bracket. The operation is simple and quick, improving the efficiency of installation and disassembly.

[0013] 2. The support bracket has a U-shaped structure and two sets are arranged in parallel. Correspondingly, the fixing plates are also set with the support bracket, and a connecting plate is provided between the two sets of fixing plates. This structural design can effectively increase the stability when installing a section of ventilation duct, prevent the ventilation duct from shaking or shifting during operation, and ensure the stable operation of the ventilation system.

[0014] 3. The system includes telescopic components such as a fixed cylinder, a sliding cylinder, and a screw. By rotating the screw, the fixed cylinder slides on the sliding cylinder, thereby adjusting the height of the ventilation duct at the bottom. This allows for easy adjustment of the height of a section of the ventilation duct to meet different installation requirements and facilitates the connection between several ventilation ducts. This adjustable height design enables the ventilation duct to better adapt to different spatial layouts and installation environments during installation, improving installation flexibility.

Detailed Implementation

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, this utility model proposes a structure for easy installation of ventilation ducts, including a ventilation duct 1. The bottom of the ventilation duct 1 is provided with a support bracket 2, and the top of the support bracket 2 is provided with a bending plate 3. The bending plate 3 is provided with a first groove 4. The top of the support bracket 2 is detachably connected to a fixing plate 5. The two ends of the fixing plate 5 are provided with second grooves 6 corresponding to the first groove 4. The second groove 6 is rotatably connected to a stud 7 via a shaft. The bottom of the stud 7 is inserted into the first groove 4, and the bottom of the stud 7 is threadedly connected to a nut 8. When it is necessary to disassemble a certain section of the ventilation duct 1, the ventilation duct 1 is dragged from the bottom, the nut 8 is loosened, and the stud 7 is unscrewed from the second groove 6 of the fixing plate 5, so that the ventilation duct 1 and the support bracket 2 can be removed.

[0023] like Figure 1As shown, the support bracket 2 is U-shaped and has two sets of parallel support brackets. The fixing plate 5 is correspondingly arranged with the support bracket 2, and a connecting plate 9 is provided between the two sets of fixing plates 5. The arrangement of the two sets of support brackets 2 can increase the stability when installing a section of ventilation duct 1.

[0024] like Figure 3 As shown, the connecting plate 9 is provided with a telescopic component 10, and the top of the telescopic component 10 is provided with a mounting plate 11. The mounting plate 11 is provided with mounting holes 12. The height of a certain section of ventilation duct 1 can be adjusted through the telescopic component 10 so that several ventilation ducts 1 can be connected.

[0025] like Figure 4 As shown, the telescopic component 10 includes a fixed cylinder 13, a sliding cylinder 14, and a screw 15. The bottom end of the fixed cylinder 13 is fixed to the connecting plate 9. Several ribs 20 are provided between the bottom end of the fixed cylinder 13 and the connecting plate 9. The sliding cylinder 14 is slidably sleeved on the fixed cylinder 13. A baffle 16 is provided on the inner side wall of the top of the sliding cylinder 14. The screw 15 is threadedly connected to the fixed cylinder 13, and its top end rotates through the baffle 16 and is rotatably connected to the inner top wall of the sliding cylinder 14. By rotating the screw 15, the fixed cylinder 13 slides on the sliding cylinder 14, thereby driving the bottom ventilation duct 1 to adjust its height, which facilitates the connection of the duct.

[0026] like Figure 4 As shown, the inner wall of the slide cylinder 14 is rotatably provided with a driving bevel gear 17, and a driven bevel gear 18 is fixedly sleeved on the screw 15. The driven bevel gear 18 meshes with the driving bevel gear 17. The driven bevel gear 18 is located above the baffle 16. The side wall of the slide cylinder 14 is provided with a handle 19 that rotatably passes through its side wall and is connected to the driving bevel gear 17. Rotating the handle 19 drives the driving bevel gear 17 to rotate, the driving bevel gear 17 drives the driven bevel gear 18 to rotate, and the driven bevel gear 18 drives the screw 15 to rotate.

[0027] In practical use, the ventilation duct 1 is placed inside the support bracket 2, with its bottom fitting against the support bracket 2. The fixing plate 5 is installed on the top of the support bracket 2 through the cooperation of the slot 6 and the stud 7. The bottom of the stud 7 is inserted into the slot 4 of the bending plate 3, and the nut 8 is tightened to firmly connect the fixing plate 5 and the support bracket 2, thereby fixing the ventilation duct 1 on the support bracket 2.

[0028] When adjusting the height of the ventilation duct 1 according to the installation space requirements, the drive bevel gear 17 drives the driven bevel gear 18 to rotate by rotating the handle 19, which in turn drives the screw 15 to rotate, so that the fixed cylinder 13 slides on the slide cylinder 14, adjusting the ventilation duct 1 to a suitable height, so that different sections of the ventilation duct 1 can be smoothly connected.

[0029] When it is necessary to disassemble a section of ventilation duct 1 for maintenance, replacement or other operations, first hold the section of ventilation duct 1 from the bottom, use a tool to loosen the nut 8, unscrew the stud 7 from the slot 6 of the fixing plate 5, disconnect the connection between the fixing plate 5 and the support bracket 2, and then remove the support bracket 2 and ventilation duct 1 together to complete the disassembly operation of ventilation duct 1.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
