Description

Technical Field

[0001] This application relates to the field of duct installation equipment, and in particular to a duct hanger. Background Technology

[0002] Air ducts are a common type of ventilation equipment, often used to transport gases to buildings or equipment. Typically, air ducts are fixed to the top of a building using hangers.

[0003] In the existing related technologies, you can refer to the patent document with publication number CN 117588633 A, which discloses an all-round anti-seismic support bracket. By covering the air duct with a limiting frame and then fixing it to the fixing block, the air duct is not easy to shake under the action of external force.

[0004] Regarding the aforementioned technologies, the shape of the limiting frame is relatively fixed, making it inconvenient to fix air ducts with different cross-sectional sizes, resulting in poor applicability of the hanger. Summary of the Invention

[0005] To ensure the applicability of the hanger, this application provides a duct hanger.

[0006] The duct hanger provided in this application adopts the following technical solution:

[0007] A duct hanger includes a hanger crossbar, a hanger vertical bar, and a locking component;

[0008] The hanger has two horizontal bars, which are distributed vertically, and two vertical bars, which are distributed horizontally. A duct fixing hole is formed between the two horizontal bars and the two vertical bars for the air duct to pass through.

[0009] The vertical rod of the hanger is movably fitted to the horizontal rod of the hanger, and a transmission link is provided between the horizontal rod and the vertical rod of the hanger. The two ends of the transmission link are respectively rotatably fitted to the horizontal rod and the vertical rod of the hanger.

[0010] The locking element is used to bring the two hanger crossbars closer to each other or further apart. When the two hanger crossbars bring the two hanger vertical bars closer to each other or further apart, the two hanger vertical bars will correspondingly bring the two hanger vertical bars closer to each other or further apart.

[0011] By adopting the above technical solution, when installing the air duct, the air duct is inserted through the air duct fixing hole, and then the locking device makes the horizontal bar and vertical bar of the hanger move towards the air duct simultaneously until the air ducts with different cross-sectional sizes are clamped in both the horizontal and vertical directions, thereby ensuring the applicability of the hanger.

[0012] Optionally, the locking component includes a locking screw tube and a locking screw rod. The threads at both ends of the locking screw tube are turned in opposite directions. There are two locking screw rods. One end of each locking screw rod is threaded into both ends of the locking screw tube, and the other end of each locking screw rod is connected to two hanger crossbars.

[0013] By adopting the above technical solution, the two locking screws can be moved closer or further apart by rotating the locking screw tube, thereby causing the two hanger crossbars to move closer or further apart.

[0014] Optionally, the locking screw is rotatably engaged with the crossbar of the hanger.

[0015] By adopting the above technical solution, it is convenient to adjust the crossbar of the hanger by rotating the locking screw when there are fewer installation personnel.

[0016] Optionally, the outer circumferential surface of the locking screw tube is provided with anti-slip texture.

[0017] By adopting the above technical solution, installers can rotate the locking screw to a greater extent, making the duct more stably fixed.

[0018] Optionally, the horizontal bar of the hanger is horizontally slidable and fitted with a horizontal slider, and the vertical bar of the hanger is vertically slidable and fitted with the horizontal slider.

[0019] By adopting the above technical solution, when the horizontal bar of the hanger moves in the vertical direction, the horizontal slider moves in the horizontal direction and moves vertically along the vertical bar of the hanger, so that when the two horizontal bars of the hanger approach each other, the two vertical bars of the hanger approach each other.

[0020] Optionally, each of the hanger vertical rods is provided with at least two transmission links, and the axes of the plurality of transmission links intersect or are not parallel.

[0021] By adopting the above technical solution, it is beneficial to improve the stability of the hanger vertical rod, making it less likely to sway when the hanger horizontal rod is adjusted.

[0022] Optionally, the transmission link is rotatably engaged with the hanger vertical rod via an adjusting slider, and the adjusting slider is vertically and adjustablely mounted on the hanger vertical rod.

[0023] By adopting the above technical solution, it is convenient to adjust the position of the hanger vertical rod according to the cross-sectional shape of the air duct, so that both the hanger vertical rod and the hanger horizontal rod are tightly fitted against the outside of the air duct, thereby further ensuring the applicability of the hanger.

[0024] Optionally, the horizontal bar of the hanger is equipped with a horizontal bar buffer pad, which faces the duct fixing hole, and the vertical bar of the hanger is equipped with a vertical bar buffer pad, which faces the duct fixing hole.

[0025] By adopting the above technical solution, it is easy to ensure that both the vertical and horizontal members of the hanger are tightly fitted against the outside of the duct.

[0026] Optionally, the material of the crossbar buffer pad and / or the vertical bar buffer pad is rubber.

[0027] By adopting the above technical solutions, it is beneficial to ensure the durability of the horizontal bar buffer pads and / or vertical bar buffer pads.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When installing the air duct, pass the air duct through the air duct fixing hole, and then use the locking device to make the horizontal and vertical bars of the hanger move towards the air duct simultaneously until air ducts of different cross-sectional sizes are clamped in both the horizontal and vertical directions, thereby ensuring the applicability of the hanger.

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a duct hanger. (Refer to...) Figure 1 and Figure 2 The duct hanger includes a hanger horizontal bar 1, a hanger vertical bar 2, and a locking component 3.

[0036] Reference Figure 2 There are two hanger crossbars 1, which are distributed vertically. Both hanger crossbars 1 are set horizontally, and the material of the hanger crossbars 1 is a flexible metal. The top hanger crossbar 1 is fixedly connected to several hinge seats, which are used to install the hanger crossbar 1 to the roof of the building.

[0037] Reference Figure 2There are two vertical hanger rods 2, which are distributed horizontally and vertically. The two horizontal hanger rods 1 and the two vertical hanger rods 2 are arranged in a rectangular shape, and duct fixing holes for duct installation are formed between the two horizontal hanger rods 1 and the two vertical hanger rods 2.

[0038] Reference Figure 2 A horizontal bar buffer pad 11 is fixedly installed on the horizontal bar 1, and the buffer pad 11 is located near the middle of the horizontal bar 1, facing the duct fixing hole. A vertical bar buffer pad 21 is fixedly installed on the vertical bar 2, and the buffer pad 21 is located near the middle of the vertical bar 2, facing the duct fixing hole. Furthermore, the horizontal bar buffer pad 11 and the vertical bar buffer pad 21 are arranged in a "+" shape, and both the horizontal bar buffer pad 11 and the vertical bar buffer pad 21 are made of elastic material, preferably rubber.

[0039] Reference Figure 2 and Figure 3 Two locking components 3 are provided, distributed horizontally and located outside the duct fixing hole. Each locking component 3 includes a locking screw tube 31 and two locking screws 32, both arranged vertically. The threads at both ends of the locking screw tube 31 rotate in opposite directions, and the outer side of the locking screw tube 31 has anti-slip grooves to facilitate rotation by the operator. The top of one locking screw 32 is rotatably engaged with the top hanger crossbar 1, and the bottom thread of this locking screw 32 is engaged with the top of the locking screw tube 31. The top thread of the other locking screw 32 is engaged with the bottom end of the locking screw tube 31, and the bottom rotatably engages with the bottom hanger crossbar 1. This allows the two hanger crossbars 1 to move closer or further apart by rotating the locking screw tube 31, thereby adjusting the size of the duct fixing hole.

[0040] Reference Figure 3 The horizontal bar 1 of the hanger slides horizontally with two horizontal sliders 12, each corresponding to a vertical bar 2 of the hanger. The vertical bar 2 slides vertically with the horizontal sliders 12 and can slide through the horizontal sliders 12. A transmission link 4 is provided between the horizontal bar 1 and the vertical bar 2, and each vertical bar 2 has two or more transmission links 4. In this embodiment, each vertical bar 2 has two transmission links 4, for a total of four transmission links 4, which are arranged in an "X" shape so that the axes of the four transmission links 4 intersect or are not parallel.

[0041] One end of the transmission link 4 is rotatably connected to the horizontal bar 1 of the hanger, and the other end of the transmission link 4 is rotatably connected to the vertical bar 2 of the hanger via an adjusting slider 41. The adjusting slider 41 is adjustablely mounted on the vertical bar of the hanger, and the transmission link 4 is rotatably engaged with the adjusting slider 41 so that when the horizontal bars 1 of the hanger move closer or further apart, the two vertical bars 2 of the hanger move closer or further apart accordingly. Specifically, in this embodiment, the adjusting slider 41 includes two clamping blocks connected by bolts (not shown in the figure), so that the position of the adjusting slider 41 can be adjusted by rotating the bolts.

[0042] The implementation principle of a duct hanger in this application embodiment is as follows: When installing the duct, the duct is inserted through the duct fixing hole, and then the horizontal bar 1 and the vertical bar 2 of the hanger are moved toward the duct simultaneously by rotating the locking screw 31 until the ducts with different cross-sectional sizes are clamped in both the horizontal and vertical directions, thereby ensuring the applicability of the hanger.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
