Embedded light fitting of improved fixing device

Abstract

The invention discloses an embedded light fitting of an improved fixing device, which comprises a light fitting shell, an outward hem arranged at an opening of the light fitting shell, a symmetrical clamping arm arranged on an outer wall of the light fitting shell and used for fixing the light fitting shell, and an elastic component connected with the clamping arm, wherein the head end of the clamping arm is arranged at an opening close to the light fitting shell; the tail end of the clamping arm can swing up and down around the head end of the clamping arm; the light fitting shell above the clamping arm is provided with a fixing hole; the elastic component is a long-strip elastic sheet which comprises a positioning end and a fixed end; the fixed end is connected with the tail end of the clamping arm; the positioning end is provided with a lug blocked at the fixed hole; when the clamping arm is unfolded, the lug of the positioning end of the elastic sheet is blocked at the fixed hole; and when the clamping arm is folded towards the light fitting shell, the lug of the positioning end of the elastic sheet breaks away from the fixed hole, and the elastic sheet is brought into the fixed hole. The embedded light fitting of the improved fixing device has the advantages of simple structure, simple and easy operation, stable mounting, convenient dismounting and mounting and the like.

Description

【Technical field】 [0001] The invention relates to a fixing device of a lamp, in particular to an embedded lamp with an improved fixing device. 【Background technique】 [0002] At present, the fixing of recessed lamps generally adopts torsion spring structure, such as Figure 14 As shown, the two ends of the torsion spring 100 are respectively a mounting end 101 for fixing the lamp and a clamping end 102 which forms a certain angle with the mounting end. This structure is clamped and fixed by the installation end and the clamping end touching the back and side of the ceiling respectively. During installation, the installation end of the torsion spring should be retracted by hand and then inserted into the hole. When holding the end and pressing down the clamping end 102, drive the installation end 101 to press down, as Figure 15 As shown, until the two ends of the torsion spring are clamped and fixed on the ceiling to complete the installation of the lamp, such as Figure 1...

AI Technical Summary

Problems solved by technology

Therefore, it is impossible for the finished lamps and lanterns with the torsion spring to be suitable for all ceiling installations with different thicknesses, and its adaptability is poor, such as Figure 18 As shown, when the luminaire with a higher position of the torsion spring is installed on a thinner ceiling, the installation will be unstable, the surface of the luminaire will not stick, and even cause the luminaire to fall; Figure 19 As shown, when the luminaire with a lower position of the torsion spring is installed on a thicker ceiling, there will be problems that the ceiling cannot be clamped and the installation is unstable

Even in the same ceiling, the installation effect will be affected if the installation opening is too large or too small. Large, it will cause the torsion spring clamping is not firm, the installation is not stable, the lamp surface is not sticking, etc., such as Figure 20 and 21 It shows that the scope of application is limited, and the specifications of lamps and lanterns are required to be relatively increased for different installation places, which increases the cost of molds and inventory

After installing the recessed lamp with the above-mentioned structure on the ceiling, it is difficult to remove the lamp from the ceiling when there is a problem with the lamp and needs to be repaired during use in the future. many troubles
