Explosion-proof lamp

Abstract

The invention relates to an explosion-proof lamp which comprises an upper casing, a lower casing and a switching mechanism, wherein the switching mechanism locks the upper casing and the lower casing and comprises multiple groups of pressing buckle assemblies and at least one group of limiting mechanism arranged rotatably. Each pressing buckle assembly comprises a support pillar, a wrenching piece and a pressing rod; the support pillar is fixedly arranged on the lower casing, a rotating shaft is movably arranged on the support pillar and is arranged on the wrenching piece in a penetrating way; one end part of the wrenching piece is a free end, and the limiting mechanism contacts with and presses the free end; the other ends of the wrenching piece are two limiting ends arranged oppositely, and the limiting ends are rotatably arranged on the rotating shaft; hole positions are arranged in the limiting ends, and the pressing rods are rotatably arranged in the hole positions. The explosion-proof lamp has the following beneficial effects: locking and buckling of the upper casing and the lower casing of the lamp are realized due to the arrangement of the pressing buckle assemblies, and the limiting mechanism presses the free ends of the multiple groups of pressing buckle assemblies, so as to achieve the purpose of preventing operators from directly tearing the pressing buckle assemblies, and the limiting mechanism is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the field of lighting fixtures, more specifically, to an explosion-proof lighting fixture. Background technique [0002] At present, there are two types of switch mechanisms for explosion-proof lamps: one is to directly use screws to tighten the lamps. In this structure, the screws must be loosened one by one to open the shell of the lamps. The locking buckle on the connecting rod cooperates to realize the locking of the upper and lower shells of the lamp. In this structure, the switch structure is linked with the gear, and the connecting rod is equipped with a lamp locking buckle. The buckle is used to control the locking and opening of the lamp, and the switch can only be rotated and opened with a special tool, which has a high production cost and a complicated structure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an explosion-proof lamp which can well solve...
