Snap connection device and lamps

Abstract

The invention is suitable for the luminaire field, providing a snap fit connecting device used for connecting a front cover and a rear cover of a luminaire. The snap fit connecting device comprises a hook hinged with the rear cover and a spring clamped with the front cover. The spring comprises an arched substrate, a first clamping hook that can be hinged with the hook extends from one end of the substrate to one side, a second clamping hook that can be clamped with the front cover extends from the other end of the substrate to the side opposite to the first clamping hook. The substrate central section is provided with an outward bent clamping tongue, and an tail of the tongue projects out of the second clamping hook. Through the hook and the spring, the buckle connecting device of the invention can reliably connects the front cover and the rear cover of the luminaire together, and enables the rear cover to be opened conveniently, so is quite beneficial for maintenance of the luminaire, and can enhance the work efficiency of the maintenance personnel greatly.

Description

technical field [0001] The invention belongs to the field of lamps, in particular to a buckle connection device with reliable connection and convenient disengagement and a lamp including the buckle connection device. Background technique [0002] In a common sealed lighting system, because the life of the light source is usually relatively short, it is often necessary to open the cover to replace the light source within the service life of the lamp. At the same time, since the lamp is generally installed at a high place, the lamp cover still It must be connected with the lamp housing to facilitate the replacement of the light source. In the process of opening the cover, due to the different installation methods, the flipping direction of the lamp cover may be different, which requires that the buckle connection device used to fasten the lamp cover can not only be connected reliably, but also can be easily disengaged to facilitate operation. The personnel successfully opened...
