Connection structure of lamp base and explosion-proof movable lamp with connection structure of lamp base

Abstract

The invention provides a connection structure of a lamp base. The connection structure comprises a fixed shaft, a middle shaft and a connecting shaft, wherein one end of the middle shaft is rotatably connected with the fixed shaft by use of a first rotating shaft, and the first rotating shaft is arranged perpendicularly to the fixed shaft; a cambered limiting groove is formed in one end, far away from the fixed shaft, of the middle shaft, the corresponding central angle of the cambered limiting groove is smaller than 180 degrees, and the chord of the cambered limiting groove is arranged in parallel to the first rotating shaft; a receiving part is arranged at one end of the connecting shaft; one end, far away from the fixed shaft, of the middle shaft is received in the receiving part, and the middle shaft is taken as the rotating shaft of the connecting shaft; a limiting through hole is formed in the sidewall of the receiving part, and the connecting shaft is fixed on the middle shaft by use of a limiting column which is put through the limiting through hole and connected against the cambered limiting groove; two mounting plates are arranged on one end, far away from the middle shaft, of the connecting shaft; a mounting through hole for mounting the lamp base is formed in each mounting plate, and the connection line of the centers of the two mounting through holes is parallel to the limiting column. The invention also provides an explosion-proof movable lamp with the connection structure of the lamp base; the lamp base of the lamp can be adjusted in three spatial directions.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a connection structure of a lamp cap and an explosion-proof mobile lamp adopting the connection structure of the lamp cap. Background technique [0002] Many existing lamp caps are fixed, and the angle adjustment of the lamp cap is limited, usually only adjustable in one or two directions, which is not enough to meet the needs of illumination from various angles. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide a connection structure of a lamp cap with a multi-directional angle adjustment function and an explosion-proof mobile lamp using the connection structure of the lamp cap. [0004] A connection structure of a lamp cap, comprising: [0005] fixed shaft; [0006] An intermediate shaft, one end of which is rotatably connected to one end of the fixed shaft through a first rotating shaft, the first rotating shaft and the fixed shaft are arranged v...
