Abstract

The invention discloses a rotatable electrodeless focal length-adjusting antiexplosion flashlight, comprising a head ring, a head, a focusing ring, a large body, a tail cover, a switch cap, a head neck, a lens, an LED lamp panel, a control panel, a battery, a circuit board press ring, a switch panel, a switch spring, a copper cap, a switch cap press ring, a copper cap insulating ring, a lamp holder, a lamp panel press ring, an elastic bead and a spring. The rotatable electrodeless focal length-adjusting antiexplosion flashlight is reasonable in design, has higher antiexplosion and waterproof effects, and is more efficiency, energy-saving and environment-friendly, has multiple protection functions, and is compact in appearance and portable, and the rotatable electrodeless focusing functionand high waterproof performance are increased; in addition, the rotatable electrodeless focal length-adjusting antiexplosion flashlight also has the advantages of high lightness and convenience and rapidity in adjustment of light condensation and light dispersion.

Description

technical field [0001] The invention relates to a flashlight, in particular to an explosion-proof flashlight with rotatable stepless focus adjustment. Background technique [0002] Explosion-proof flashlights are used for fire protection, electric power, industrial and mining enterprises and other flammable and explosive places to provide mobile lighting. It can be provided in the process of geological exploration, tourism exploration, border patrol, coastal defense patrol, rescue and disaster relief, field operation, tunnel operation, forest fire prevention, airport inspection, railway inspection, archaeology and fire command, criminal investigation, traffic accident handling, electric power repair, etc. illumination. Since no sparks are generated when the power is turned on, there is no possibility of explosion due to sparks in a dangerous space, and the explosion-proof effect is achieved, so it is called an explosion-proof flashlight. At present, the aluminum alloy expl...
