Description

Fastener for fastening shell of LED projection lamp Technical Field The utility model relates to the technical field of LED projection lamps, in particular to a buckle fastener of an LED projection lamp shell. Background The projection lamp is a lamp with the illumination intensity higher than the surrounding environment on the appointed illuminated surface, can aim at any direction, has a structure which is not influenced by the climate conditions, is installed indoors in real life, generally, the tail part of the projection lamp is arranged in a reserved hole in the ceiling in a penetrating mode, is clamped with the top surface of the ceiling through a spring buckle, and the end part of the projection lamp is exposed from the bottom surface of the ceiling, so that the projection lamp is small in size and attractive. Because the spring clamp card is at the top surface of ceiling, consequently, when dismantling the projecting lamp, need break the spring clamp off with the fingers and the ceiling separation, but the internal diameter in preformed hole generally with the external diameter looks adaptation of projecting lamp, people are difficult to pack into the ceiling upside with the finger, and then be difficult to break off the spring clamp, can only be through the downdraw projecting lamp of messenger's strength for the spring clamp takes place deformation, and pulls out from the preformed hole, damage the ceiling easily, and after pulling out, the spring clamp can strike the outer wall of projecting lamp under elastic effect, can hit the finger that the user held the projecting lamp, there is certain potential safety hazard. Therefore, in order to solve the above-mentioned problem, a fastening device for fastening a housing of an LED projector is proposed. Disclosure of utility model The utility model aims to provide a fastener for fastening a shell of an LED projection lamp, which aims to solve the problems that in the prior art, the inner diameter of a preformed hole is generally matched with the outer diameter of the projection lamp, people are difficult to plug fingers into the upper side of a ceiling, and then the spring clamp is difficult to break off, the projection lamp can be pulled down by only being pulled down forcefully, so that the spring clamp is deformed and pulled out of the preformed hole, the ceiling is easy to damage, and after the spring clamp is pulled out, the spring clamp can strike the outer wall of the projection lamp under the elastic action, the fingers of a user holding the projection lamp can be hit, and a certain potential safety hazard exists. The technical scheme includes that the fastener comprises a ceiling, wherein a reserved groove is formed in the surface of the ceiling, a lamp body is mounted on the inner side of the reserved groove, two groups of connecting blocks are arranged on the surface of the lamp body, and spring clamps are clamped on the inner sides of the connecting blocks; Install the promotion structure on the lamp body, the promotion structure includes rotatory cover, rotatory cover is established in the outside of lamp body, integrated into one piece has friction line on the outer wall of rotatory cover, the annular has been seted up on the inner wall of rotatory cover, the butt groove has been seted up to the top surface of rotatory cover, integrated into one piece has the card ball on the outer wall of lamp body.
