Description

Technical Field

[0001] This utility model belongs to the field of ventilation duct support technology, and specifically relates to a quick-installation ventilation duct support. Background Technology

[0002] Currently, a Chinese utility model patent with announcement number CN222479687U discloses a ventilation duct installation bracket; although this patent can simultaneously install and fix multiple ventilation ducts, improving the installation efficiency of ventilation ducts.

[0003] However, when multiple ventilation ducts are installed with inconsistent diameters, it becomes impossible to effectively limit and fix the smaller diameter duct; all ducts with the same diameter must be installed simultaneously. Furthermore, the height adjustment of the ventilation duct support is limited by the adjustment groove, thus allowing adjustment only at a fixed height, which is inconvenient for practical use. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-installation ventilation duct bracket, which has the advantages of facilitating the simultaneous installation and fixing of multiple ventilation ducts with different diameters and the ability to adjust the height of the ventilation ducts.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-installation ventilation duct bracket, including a support plate, with placement grooves on both sides of the top of the support plate, and a bidirectional screw rod rotatably connected to the support plate at the bottom of the inner cavity of the placement groove, with threaded sleeves threaded onto both sides of the surface of the bidirectional screw rod, and trapezoidal abutments slidably connected to the support plate welded to the top of the two threaded sleeves, with a first bevel gear bolted to one end of the bidirectional screw rod, a second bevel gear meshing on the side of the first bevel gear away from the bidirectional screw rod, and a rotating rod rotatably connected to the support plate bolted to the bottom of the second bevel gear.

[0006] The above technical solution utilizes two threaded sleeves that slide closer together according to the diameter of the ventilation duct, clamping the smaller-diameter duct inside the placement slot. This facilitates the simultaneous installation and fixing of multiple ventilation ducts with different diameters, improving installation efficiency. The height is adjusted by sliding the telescopic rod downwards inside the fixing cylinder, and locked by rotating the limit bolt to engage with the threads of the fixing cylinder. This not only facilitates height adjustment of the ventilation duct, but the spring's return force also automatically resets the telescopic rod for convenient and quick storage.

[0007] The present invention is further configured such that: a threaded rod is rotatably connected to the top of the support plate, a threaded ring is threadedly sleeved on the surface of the threaded rod, pressure plates are provided on both sides of the surface of the threaded ring, a threaded shaft is provided at the top of the placement groove and threadedly connected to the pressure plate, and a clamping plate is bolted to the bottom of the threaded shaft.

[0008] By using the above technical solution, the screw shaft is rotated to move the clamping plate downward, thereby pressing down and limiting the top of the ventilation duct with a small diameter.

[0009] The present invention is further configured such that: telescopic rods are bolted to both sides of the top of the support plate; a fixed cylinder is slidably sleeved on the surface of the telescopic rod; a limiting bolt that is threaded through and engages with the telescopic rod is threaded to one side of the bottom of the fixed cylinder; a sliding plate that is slidably connected to the fixed cylinder is welded to the top of the telescopic rod; and springs that are bolted to the sliding plate and the fixed cylinder are respectively sleeved inside the fixed cylinder on the telescopic rod.

[0010] The above technical solution not only facilitates the height adjustment of the ventilation duct, but also allows the spring's rebound force to automatically reset the telescopic rod, making it convenient and quick to store.

[0011] The present invention is further configured such that: both sides of the surface of the threaded ring are welded with sliding sleeves, one end of the pressure plate near the threaded ring is bolted to the sliding sleeve, and the top of the support plate is welded with a positioning rod that is threadedly connected to the sliding sleeve.

[0012] By adopting the above technical solution, the up-and-down sliding of the threaded ring is limited, thereby improving the sliding stability of the pressure plate.

[0013] The present invention is further configured such that an anti-slip pad is adhered to the inner surface of the placement groove.

[0014] By adopting the above technical solution, the friction of the ventilation duct placed inside the placement slot is increased, thereby improving the placement stability.

[0015] The present invention is further configured such that a limiting block that works in conjunction with a threaded sleeve is fixedly sleeved at the center of the surface of the bidirectional screw.

[0016] By adopting the above technical solution, the sliding distance of the threaded sleeve on the surface of the bidirectional screw can be limited by setting a limit block.

[0017] The present invention is further configured such that a mounting screw is welded to the top of the fixed cylinder.

[0018] Using the above technical solution, the top of the fixed cylinder is bolted and fixed by using installation screws, thereby hoisting the ventilation duct placed inside the placement slot.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By rotating and adjusting two threaded sleeves according to the diameter of the ventilation duct, the smaller diameter ventilation duct is clamped inside the placement groove. This facilitates the simultaneous installation and fixing of multiple ventilation ducts with different diameters, improving the efficiency of ventilation duct installation;

[0021] 2. The height is adjusted by sliding the telescopic rod downwards inside the fixed cylinder, and then locking it by rotating the limit bolt to engage with the threads of the fixed cylinder. This not only facilitates height adjustment of the ventilation duct, but the spring's return force also causes the telescopic rod to automatically return to its original position for easy and quick storage.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 , Figure 3A quick-installation ventilation duct bracket includes a support plate 1. The support plate 1 has placement grooves 5 on both sides of its top. A bidirectional screw 6, rotatably connected to the support plate 1, is located at the bottom of the inner cavity of each placement groove 5. Threaded sleeves 7 are threaded onto both sides of the surface of the bidirectional screw 6. Trapezoidal abutments 8, slidably connected to the support plate 1, are symmetrically welded to the top of each threaded sleeve 7. A first bevel gear 9 is bolted to one end of the bidirectional screw 6. A second bevel gear 11 meshes with the side of the first bevel gear 9 away from the bidirectional screw 6. A rotating rod 10, rotatably connected to the support plate 1, is bolted to the bottom of the second bevel gear 11. By rotating and adjusting the two threaded sleeves 7 according to the diameter of the ventilation duct, the smaller diameter ventilation duct is clamped inside the placement groove 5. This facilitates the simultaneous installation and fixing of multiple ventilation ducts with different diameters, improving the efficiency of ventilation duct installation.

[0030] refer to Figure 1 , Figure 2 A threaded rod 2 is rotatably connected to the top of the support plate 1. A threaded ring 3 is threadedly fitted onto the surface of the threaded rod 2. Pressure plates 4 are provided on both sides of the surface of the threaded ring 3. A threaded shaft 19, threaded through and threadedly connected to the pressure plate 4, is provided at the top of the placement groove 5. A clamping plate 20 is bolted to the bottom of the threaded shaft 19. By rotating the threaded shaft 19, the clamping plate 20 is moved downward, thereby pressing down and limiting the top of the ventilation duct with a small diameter.

[0031] refer to Figure 1 , Figure 2 Both sides of the threaded ring 3 are welded with sliding sleeves 17. The end of the pressure plate 4 near the threaded ring 3 is bolted to the sliding sleeve 17. The top of the support plate 1 is welded with a positioning rod 18 that is threaded through the sliding sleeve 17. This limits the up-and-down sliding of the threaded ring 3 and improves the sliding stability of the pressure plate 4.

[0032] refer to Figure 2 , Figure 3 A limiting block 22, which works in conjunction with a threaded sleeve 7, is fixedly sleeved at the center of the surface of the bidirectional screw 6. By setting the limiting block 22, the sliding distance of the threaded sleeve 7 on the surface of the bidirectional screw 6 can be limited.

[0033] Brief description of the usage process: First, the ventilation duct is placed inside the placement slot 5. Then, rotating the rotating rod 10 drives the second bevel gear 11 to mesh with the first bevel gear 9, causing the bidirectional screw 6 to rotate inside the support plate 1. Next, the bidirectional screw 6 engages with two threaded sleeves 7, causing them to slide closer together, clamping the ventilation duct inside the placement slot 5 according to its diameter. Finally, rotating the threaded rod 2 engages with the threaded ring 3, causing the pressure plate 4 to move downwards to press and fix the ventilation duct. Rotating the threaded shaft 19 separately moves the clamping plate 20 downwards, thus limiting the pressure on the top of the ventilation duct according to its diameter.

[0034] Example 2:

[0035] refer to Figure 1 , Figure 2 , Figure 4 A quick-installation ventilation duct bracket is disclosed. Telescopic rods 12 are bolted to both sides of the top of a support plate 1. A fixed cylinder 13 is slidably sleeved on the surface of each telescopic rod 12. A limiting bolt 14, threaded through one side of the bottom of the fixed cylinder 13, engages with the telescopic rod 12. A sliding plate 15, slidably connected to the fixed cylinder 13, is welded to the top of the telescopic rod 12. A spring 16, bolted to both the sliding plate 15 and the fixed cylinder 13, is sleeved inside the fixed cylinder 13. The height is adjusted by sliding the telescopic rod 12 downwards inside the fixed cylinder 13, and locked by rotating the limiting bolt 14 to engage with the threaded connection of the fixed cylinder 13. This not only facilitates height adjustment of the ventilation duct but also allows the spring 16 to automatically reset the telescopic rod 12 for easy and quick storage.

[0036] refer to Figure 1 An anti-slip pad 23 is adhered to the inner surface of the placement slot 5. This increases the friction of the ventilation duct inside the placement slot 5, improving placement stability.

[0037] refer to Figure 1 , Figure 2 A mounting screw 21 is welded to the top of the fixed cylinder 13. The top of the fixed cylinder 13 is bolted and fixed by the mounting screw 21, thereby allowing the ventilation duct placed inside the placement slot 5 to be hoisted.

[0038] Brief description of usage: The top of the fixed cylinder 13 is bolted in place. Then, by rotating the limiting bolt 14, which engages with the threaded connection of the fixed cylinder 13, it is loosened from the surface of the telescopic rod 12. This allows the telescopic rod 12 to slide downwards, adjusting the height of the ventilation duct inside the placement slot 5. The limiting bolt 14 is then rotated again to tighten the limit. Simultaneously, after the ventilation duct is removed from the placement slot 5, the telescopic rod 12 can be moved up and down by the rebound force of the spring 16, allowing the telescopic rod 12 to automatically slide back into the fixed cylinder 13 for storage.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
