Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0022] Such as Figure 1-Figure 2 As shown, this embodiment provides a fixing device for a large-scale lamp or ceiling fan buried in an electric lamp holder box concealed in a floor. Tube 2. This device is made of steel material, as long as the original lamp head box is used, if it is necessary to install a super-large lamp of hundreds of kilograms, it is only necessary to pre-embed multiple electric lamp head boxes as appropriate.
[0023] Such as figure 2 As shown, the fixing device includes an outer sleeve 6, an inner sleeve 10 and lifting lugs 9, the outer sleeve 6 is set outs...

The invention relates to a large lamp or ceiling fan fixing device in an electric lamp holder box buried in a floor slab in a hidden manner. The fixing device is mounted in the electric lamp holder box (1) which is buried in the floor slab in the hidden manner, wherein joint pipes (2) are arranged at the two ends of the electric lamp holder box (1); the fixing device comprises an outer sleeve (6), an inner sleeve (10) and a lifting lug (9); the outer sleeve (6) is arranged outside the inner sleeve (10) in a sleeving manner; the inner sleeve (10) is fixedly connected with the joint pipes (2) at the two ends of the electric lamp holder box (1) to limit the movement in the horizontal and vertical directions of the outer sleeve (6); the lifting lug (9) is arranged on the outer sleeve (6); a large lamp or a ceiling fan is fixed to the lifting lug (9). Compared with the prior art, the fixing device has the advantages of being firm in fixation, convenient to mount, environment-friendly, labor-saving and the like; the original lamp holder box which is buried in the hidden manner can be utilized.
Description
technical field [0001] The invention relates to a fixing device, in particular to a fixing device for a large lamp or a ceiling fan buried in an electric lamp head box on a floor. Background technique [0002] When installing large lamps or ceiling fans, corresponding fixtures are required to cooperate with them. At present, there are basically two methods for fixing large lamps or ceiling fans: 1. Pre-embed the steel plate during the concrete pouring of the civil floor slab, and then weld the relevant components. 2. Use iron expansion bolts to fix related components. The former needs to cut the steel plate in advance, and the top steel plate must be chiseled out a few days after the pouring of the floor slab is completed, causing dust to fly and is not environmentally friendly; if there are many installations, it will take a lot of work and time. The latter requires an impact drill on the back before the iron expansion bolts are fixed, and the hole must be perpendicular t...
