DETAILED DESCRIPTION

[0021] See also Figure 1-5 , a bus duct hanger, comprising a mounting frame 1, an adjusting shell 3 is arranged below the mounting frame 1;

[0022] The mounting frame 1 is used to be fixed to the wall by bolts, and the adjustment shell 3 is used to install the adjustment component.

[0023] A spring shock absorber 2 is hinged at the bottom of the mounting frame 1, and the bottom of the spring shock absorber 2 is hinged to the top of the adjusting shell 3. The inner wall of the adjusting shell 3 is rotatably connected with a screw rod 4, one end of the screw rod 4 penetrates to the outside of the adjusting shell 3 and is fixed with a hand wheel. Three sliding sleeves 5 are arranged inside the adjusting shell 3, and the middle sliding sleeve 5 is threadedly connected to the surface of the screw 4. A connecting plate 6 is fixed to the bottom of the sliding sleeve 5, and a sliding groove is provided on the surface of the adjusting shell 3. The connecting plate 6 is slidably connected to the surface of the sliding groove. A fixing plate 7 is fixed to the bottom of the connecting plate 6, and a sliding rod 8 slides through the surface of the fixing plate 7. An adjusting plate 9 is fixed to the bottom of the sliding rod 8. Two supporting plates 10 are arranged below the adjusting plate 9, and the upper supporting plate 10 is fixedly connected to the bottom of the adjusting plate 9. Two adjusting blocks 11 are slidably connected to the surface of the supporting plate 10, and a limiting plate 12 is fixed to the surface of the adjusting block 11. Adjustment holes are provided on the surfaces of the supporting plate 10 and the adjusting block 11, and there are multiple adjustment holes on the surface of the supporting plate 10;

[0024] The spring shock absorber 2 can effectively absorb and consume the vibration energy generated by the bus duct during operation due to current changes, temperature changes, wind force, mechanical vibrations, etc., and the articulated spring shock absorber 2 can self-adjust according to the vibration amplitude, that is, as the vibration amplitude increases, the compression or extension of the spring will also increase accordingly, thereby providing an adaptive damping effect, which not only achieves good shock absorption but also avoids the rebound effect caused by excessive shock absorption. When the position of the hanger is offset during installation, resulting in the bus duct being unable to be normally inserted into the limit plates 12 on both sides, the screw rod 4 is rotated by rotating the hand wheel, so that the sliding sleeve 5 is affected by the thread and moves on the surface of the screw rod 4, so that the connecting plate 6 can be driven by the fixing plate 7, the sliding rod 8 and the adjusting plate 9. The support plate 10 is position-adjusted so that the bus duct can be normally inserted between the limit plates 12 on both sides, thereby improving the installation efficiency of the device and reducing the extra work such as re-drilling and replacing the hanger due to position deviation, thereby saving manpower, material resources and time costs. At the same time, the slide bar 8 can slide on the surface of the fixed plate 7 to adjust the height position of the support plate 10 to adapt to the different height installation requirements of the bus duct, and the limit plate 12 can drive the adjustment block 11 to slide on the inner wall of the support plate 10, so that the support plate 10 can fit the surface of the bus duct. After adjusting the position, the limit plate 12 can be positioned by using bolts to pass through the adjustment holes on the surface of the support plate 10 and the adjustment block 11, so that the device can adapt to bus ducts of various sizes.

[0025] Furthermore, the adjustment block 11 is arranged in a T-shaped structure, and the shape of the support plate 10 is adapted to the adjustment block 11;

[0026] The T-shaped adjusting block 11 can be supported by the inner wall of the supporting plate 10 , thereby preventing the adjusting block 11 from being separated from the inside of the supporting plate 10 by moving up and down.

[0027] Furthermore, the left and right sides of the support plate 10 are arranged in an open structure;

[0028] The adjusting block 11 can drive the limiting plate 12 to be taken out from the brackets of the supporting plates 10 on both sides, so that the operator can select the limiting plates 12 of different lengths according to the overall length of the bus duct.

[0029] Furthermore, a limiting sleeve 13 is fixed on the surface of the fixing plate 7, a fastening bolt 14 penetrates through the surface of the limiting sleeve 13, and a slot for matching the fastening bolt 14 is opened on the surface of the sliding rod 8;

[0030] The slide rod 8 can slide on the inner wall of the limiting sleeve 13, so that the distance between the fixed plate 7 and the adjusting plate 9 can be adjusted. After adjusting to the required position, the fastening bolt 14 is inserted into the slot on the surface of the limiting sleeve 13 and the slide rod 8, so that the adjusting plate 9 with the adjusted position can be limited.

[0031] Furthermore, a fixing nut 15 is threadedly connected to the surface of the fastening bolt 14, and the fixing nut 15 is a butterfly nut;

[0032] Twisting the fixing nut 15 into the surface of the fastening bolt 14 can limit the fastening bolt 14 to prevent the fastening bolt 14 from automatically escaping from the inside of the limiting sleeve 13, and using a butterfly nut allows the operator to rotate the fixing nut 15 without the aid of tools.

[0033] Furthermore, two support rods 17 are fixed to the inner wall of the adjustment housing 3, and the front and rear sliding sleeves 5 are both slidably connected to the surface of the support rods 17;

[0034] The front and rear sliding sleeves 5 can slide on the surface of the support rod 17 , and the support rod 17 can support the sliding sleeve 5 , so that the fixing plate 7 can be better affected by the limiting sleeve 13 , thereby improving the bearing capacity of the support plate 10 .

[0035] Furthermore, a reinforcing plate 16 is fixed to the bottom of the lower support plate 10;

[0036] The reinforcing plate 16 can reinforce the two lower support plates 10 to prevent the lower support plates 10 from shaking, thereby improving the supporting effect of the bus duct.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
