Lamp and cover opening structure thereof

Abstract

Disclosed are a lamp and a cover opening structure thereof. The cover opening structure is used for detachably connecting an upper cover and a lower cover of the lamp. A base is provided with a U-shaped groove, and containing holes are formed in two opposite side walls of the U-shaped groove of the base respectively. Two elastic parts are contained in the containing holes in the two opposite side walls of the U-shaped groove respectively. Two elastic balls are contained in the containing holes in the two opposite side walls of the U-shaped groove respectively, are close to an opening of the U-shaped groove, cannot fall off and are abutted to the elastic parts, parts of the elastic balls project out of the containing holes, and the elastic parts elastically deform and retract into the containing holes when the elastic balls are squeezed. An insert can be inserted into the U-shaped groove, and limit recesses for containing the elastic balls are formed in the insert. The insert and the base are serially connected into a power supply circuit of a light source of the lamp, and the power supply circuit of the light source of the lamp is disconnected when the insert breaks away from the he U-shaped groove of the base. The cover opening structure is high in maintenance safety, simple to operate, reusable, not easy to break and high in strength, and special tools are not needed.

Description

【Technical Field】 [0001] The invention relates to a lamp and its cover opening structure, in particular to a lamp with an upper cover and a lower cover detachably connected and its cover opening structure. 【Background technique】 [0002] At present, the lamp usually adopts an open cover structure to fix the upper cover and the lower cover of the lamp. The traditional opening structure includes: 1) connection by screws; 2) plastic buckle; 3) external buckle. [0003] However, the above-mentioned screw connection and outer buckle connection are simple to operate and unsightly, and many are limited by the appearance and structure of the product. Plastic hooks are easy to break, difficult to disassemble repeatedly, and have low reliability. At the same time, when maintenance personnel open the upper and lower covers of the above-mentioned lamp for maintenance, they are likely to get an electric shock because the lamp switch is not turned off, so the safety during maintenance is low. ...

AI Technical Summary

Problems solved by technology

[0003] However, the connection methods of the above-mentioned screw connection and external buckle are simple to operate and not beautiful, and many of them are limited by the appearance and structure of the product.

The plastic hook is easy to break, difficult to disassemble repeatedly, and has low reliability; at the same time, when the maintenance personnel open the upper and lower covers of the above-mentioned lamps for maintenance, it is easy to get an electric shock because the switch of the lamp is not closed, so the safety during maintenance is low
