[0001] The utility model relates to the technical field of exhibition hall lamp fixing, in particular to a suspension bracket for exhibition hall lamps. Background Art

[0002] Exhibition halls are important places for displaying various contents such as works of art, scientific and technological achievements, history and culture. In order to provide good lighting effects and exhibition atmosphere, various lamps are often arranged in the exhibition hall. When the indoor height is high, the design of the main lights is often arranged in a suspended manner to improve the brightness of the light. At present, the existing suspension method usually fixes expansion bolts on the roof and locks the lamp holder with the rope body. However, the height of the lamp cannot be adjusted and can only be achieved by cutting or replacing the rope body, which is time-consuming and labor-intensive. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a suspension bracket for exhibition hall lamps in response to the above-mentioned technical deficiencies. The rope body can be tightened and fixed through a tightening device, which is more convenient and reliable. When the height of the lamp changes, it can be completed by simply adjusting the position of the rope body and tightening and fixing it, which is stable and reliable.

[0031] When in use, holes are punched in advance at the top of the room and expansion bolts are installed. The two sides of the main frame 1 are fixedly connected with the expansion bolts to achieve overall suspension. Then the rope body on the lamp fixing frame is passed through the guide channel 2 and the tightening component 4 in turn. After the height reaches the specified position, the tightening component 4 is operated to cooperate with the arrangement hole 301 to tighten and fix the rope body to complete the installation operation. When the height needs to be adjusted, the tightening component 4 is loosened again, and it can be tightened again after lifting. Compared with the traditional rope body that is directly fixed, the height adjustment can be completed quickly, the construction is more convenient and quick, the intermediate operation time is shortened, and there is no need to cut the rope body to ensure the integrity of the structure. At the same time, the rope body is bent after passing through the guide channel 2, and then passed through the tightening component 4.
