Push-and-pull device for assembling and disassembling lamp

Abstract

The invention provides a push-and-pull device for assembling and disassembling a lamp. The push-and-pull device for assembling and disassembling the lamp comprises a clamp jaw, a supporting seat cylinder, a screw rod, a rotary handle and a hanging component with hanging tools replaceable. The upper end of the clamp jaw is hinged on an outer wall of the supporting seat cylinder. The screw rod is matched with the supporting seat cylinder in a threaded mode. The hanging component is hung at the lower end of the screw rod and is capable rotating around an axis of the screw rod. The replaceable hanging tools comprise a hook used for dragging and pulling, an ejection cone and an ejection rod, wherein the ejection cone and the ejection rod are used for pushing and pressing. The hanging component comprises a hanging seat. The lower end of the screw rod is connected with the upper portion of the hanging seat so that the screw rod is used for bearing pulling force or pushing force of the hanging seat. The lower portion of the hanging seat is capable of being connected with the upper portion of the hook so that the hanging seat is used for bearing pulling force of the hook. The lower portion of the hanging seat is further connected with the upper portion of the ejection cone or the ejection rod so that the hanging seat is used for bearing pushing force of the ejection cone or the ejection rod. The lower end of the screw rod is matched with the upper portion of the hanging seat in a reversed-T type and a rotary mode. The push-and-pull device for assembling and disassembling the lamp has the advantages of being capable of obviously improving opening speed of an explosion-proof lamp and reducing maintaining time of the lamp.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a quick maintenance tool for lamps. Background technique [0002] In the field of explosion-proof lighting, the tight fit of cylindrical luminaires makes it difficult to open the luminaire to maintain the light source. In order to improve the reliability of lamps and lanterns, the issue of easy maintenance has been paid more and more attention. However, there is currently no matching power-assisted mechanism for lamps. It takes more than 70 kilograms of force to manually pull out the inner core of the lamp, which increases the extra workload of maintenance. [0003] The mating surfaces of explosion-proof lamps need to be strictly sealed and tightly fitted. The interior of the lamps is subject to high heat for a long time to generate negative pressure; the aging of the sealing ring increases the possibility of bonding; factors such as long-term corrosion of the mating surfaces m...
