Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with accompanying drawing
[0020] A small-gap ceiling lamp chassis rotation fixing device, which is composed of a relatively concave chassis, a fixed metal plate, a fixed screw, and a hollow metal plate, is characterized in that: the hollow area of the hollow metal plate is larger than that of the fixed metal plate; the hollow metal plate is useful for Clamp the lower recess 4 of the fixed metal plate; there is an upper convex circle 5 on the diagonal edge of the hollow metal plate, and a screw hole 6 in the middle; the fixed metal plate has a lower concave circle 2, and the maximum distance between the two screw holes on the metal plate is less than The inside of the hollow metal plate is wide; the thickness of the fixed metal plate and the hollow metal plate is 1 to 2 millimeters; the fixed metal plate has a slope 3 that is convenient for rotation, and the closer the metal plate thickness...

Abstract
The invention relates to a small gap ceiling lamp chassis rotary fixing device, and the fixing device is composed of a relatively concave chassis, a fixing metal plate, a fixing screw and a hollow metal plate and is characterized in that the hollow area of the hollow metal plate is larger than that of the fixing metal plate, and the hollow metal plate is provided with a concave part 4 which is used for locking the fixing metal plate; the opposite angle edge of the hollow metal plate is provided with an upper gibbosity 5, and the middle of the hollow metal plate is provided with a screw hole 6; the fixing metal plate is provided with a concave circle 2, and the maximum distance of two screw holes on the metal plate is less than the width of the interior of the hollow metal plate; the thickness of the fixing metal plate and the hollow metal plate is 1 millimeter to 2 millimeters, the fixing metal plate is provided with a slant 3 which is conveniently rotated, and the thickness of the metal plate is smaller and smaller toward the edge; and an integrated ceiling lamp is directly installed, i.e., the packaged ceiling lamp is installed. The fixing device provided by the invention has the advantages that the total appearance height of the chassis is minimum, and the dismounting and maintenance are simple, thus the inconvenience is omitted when the ceiling lamp is installed and maintained, thereby improving the efficiency.
Description
technical field [0001] The patent of the present invention relates to a small gap ceiling lamp chassis rotation fixing device. Background technique [0002] At present, many ceiling lamps are installed and fixed on the top of the wall by the chassis. First, use an electric drill to drill a few holes on the top of the wall, then plug in the straight-through plastic expansion tube to fix it, and finally determine the position of the screw and screw on the screw to fix the chassis. The installation method of the ceiling lamp can only be a separate installation, that is, the chassis of the ceiling lamp is installed first, and then the lampshade of the ceiling lamp is installed. In this installation method, the chassis of the ceiling lamp and the lampshade will not overlap well due to deformation during installation, the sealing performance is not good, and it cannot effectively prevent insects from entering to form black spots, making it troublesome to clean. The patent No.: 90...
