Abstract

The main objective of the present invention is to provide maintenance mechanism for lighting equipment in a closed space of high radiation activity, which comprises a passage, a lamp base, a multi-section slide rail, a lighting handle, a stainless steel fixation plate, a lead glass lamp guard and a convex lead plug. On the top side of the passage there is a multi-section slide rail with the lamp base attached to move the lamp. The maintenance hole at the end of the passage has a convex lead plug and a stainless steel fixation plate. When the hole closes, the convex lead plug is locked to the lead plug positioning screw under the stainless steel fixation plate; while the maintenance hole opens, on the top right and top left of the stainless steel fixation plate there is a L-shaped short iron plate and a L-shaped long iron plate respectively. On the L-shaped long iron plate there is an axial screw as the axis for the convex lead plug to move and rotate. On the L-shaped short iron plate there is a lead plug positioning screw for the convex lead plug after being pulled out to have temporary fixation. At the radiation space end of the passage there is a semi-circular lead glass lamp guard for the shielding wall to be fixed without moving with the lighting equipment.
