Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a detachable and portable lighting lamp. Background Art

[0002] Workers working in mines all wear safety helmets equipped with lighting lamps. However, existing lighting lamps are installed on the safety helmets by screws or buckle structures. However, if the lighting lamps are used for a long time in mines, not only will their service life be limited, but they will also be damaged by bumps. Therefore, the lighting lamps need to be replaced. However, when the lighting lamps need to be disassembled and replaced in the dark mine, the safety helmet is located on the head of the user, and the user needs to grope for the buckle structure of the lighting lamp, which is not convenient for disassembling and installing the lighting lamp. For this reason, we propose a portable lighting lamp that is easy to disassemble and assemble. Utility Model Content

[0005] Preferably, one end of the bottom of the plastic card block is chamfered, and the chamfer facilitates guiding the plastic card block to be inserted into the inner wall of the positioning slot.

[0006] Preferably, a switch button is installed on the top outer wall of the rotating block, and the switch button is used to conveniently control the switch of the lighting lamp.

[0007] Preferably, a charging interface is provided on one side of the top of the lighting lamp, which is connected to a wire through the charging interface to facilitate charging of the lighting lamp.

[0008] Preferably, safety straps are fixedly provided on the outer walls on both sides of the bottom of the safety helmet, and a safety buckle is fixedly provided on one end of the bottom of the safety strap, so that the utility model can be conveniently fixed to the user's head through the safety strap and the safety buckle.

[0009] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0010] By bending the rotating block and the lighting lamp upward, the plastic block produces elastic deformation and opens, and the limiting teeth fixed at the bottom of the plastic block are separated from the tooth groove, and the other end of the plastic block is moved out from the inner wall of the positioning slot, so that the lighting lamp can be easily removed from the top of the safety helmet. At this time, you only need to insert the intact lighting lamp into the inner wall of the positioning slot through the bottom of the plastic block, and the limiting teeth at the bottom of the plastic block are automatically inserted into the inner wall of the tooth groove, so that the lighting lamp can be easily installed on the top of the safety helmet.
