LED tester protection device capable of preventing glass from splashing and protecting main shaft

Abstract

The invention relates to the technical field of lighting lamps, and discloses an LED tester protection device capable of preventing glass from splashing and protecting a main shaft, which comprises a rack. The upper end of the rack is movably connected with a fixing frame, the center of the rack is slidably connected with a sliding plate, the lower end of the sliding plate is fixedly connected with a pressing rod, the end, away from the sliding plate, of the pressing rod is rotationally connected with a metal feeler lever, the side face, close to the metal feeler lever, of the rack is fixedly connected with a metal strip, the interior of the rack is movably connected with an elastic cavity, and the bottom of the elastic cavity is fixedly connected with an air pump. Through unlocking the self-lock device between the movable rod and the sliding cavity, the movable rod can stretch out, the end of the movable rod is fixedly connected with a tensioning rod, and the other end of the tensioning rod is fixedly connected to the side face of the fixing frame, so that the fixing frame and the rack can be tightly connected, and the main shaft at the upper end of the fixing frame is prevented from being damaged by instantaneous air recoil force.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a protection device for an LED tester that prevents glass from splashing and protects a spindle. Background technique [0002] After the production of LED lights, it is necessary to carry out air tightness testing to prevent internal moisture in a humid environment. When the testing equipment detects poor-quality bulbs, they will explode due to the increased air pressure. Now The detection equipment cannot protect its surroundings when the LED lamp explodes. The splashed plastic and glass slag may cause damage to the surrounding facilities and personnel, and it cannot protect the main shaft at the upper end of the fixing frame. The main shaft may be severely damaged. Large reverse air impact force damages the spindle. [0003] In order to solve the above problems, the inventor provides a LED tester protection device that avoids splashing glass and protects the main sha...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a LED tester protection device that avoids splashing glass and protects the main shaft. The main shaft causes damage, and it can block the glass fragments in the event of an explosion, preventing the glass from splashing and causing harm to the surrounding personnel. It solves the problem that the detection equipment cannot protect its surroundings and splash when the LED lamp explodes. Fragments of plastic and glass may cause damage to surrounding facilities and personnel, and cannot protect the main shaft at the upper end of the fixed frame. The main shaft may be subject to a large reverse air impact force, causing damage to the main shaft
