Abstract

The invention provides a flashlight, and belongs to the field of lighting tools. The flashlight comprises a lamp barrel assembly, a lighting assembly connected with the front end of the lamp barrel assembly, a telescopic ring sleeving the periphery of the lamp barrel assembly and lighting assembly, and a lamp cap assembly connected with the front end of the telescopic ring, a first damping ring which is used for abutting against the inner wall of the telescopic ring is arranged on the periphery of the lighting assembly, a second damping ring which is used for abutting against the inner wall ofthe telescopic ring is arranged on the periphery of the lamp barrel assembly, a ventilation groove which is used for communicating the inner cavity of the telescopic ring with external air is arranged on the inner wall of the telescopic ring, and the opening direction of the ventilation groove faces to the inner part of the telescopic ring. According to the flashlight, when the focusing is carried out, the air pressure in the telescopic ring can be consistent with the air pressure of the external air, the telescopic ring does not have the phenomenon of locking or rebounding in the telescopicprocess, focusing can be carried out by using a single hand, the operation is simple, and a stepless telescopic focusing function can be achieved, the adjusting range is more flexible and the focusingeffect is better.

Description

technical field [0001] The invention belongs to the technical field of lighting tools, and more specifically relates to a flashlight. Background technique [0002] The flashlight is a hand-held lighting tool, which is widely used in nighttime workplaces. In order to better meet the needs of nighttime lighting, some flashlights have a focusing function so that the flashlight has the functions of focusing and floodlighting. Achieving different ranges of lighting. The existing adjustable focus flashlights generally require both hands to perform the focusing operation, which is not easy to operate, and the focusing process generally has a minimum adjustment unit, which cannot achieve the effect of stepless focusing, thereby limiting the convenience of the flashlight focusing operation sex. Contents of the invention [0003] The object of the present invention is to provide a flashlight to solve the technical problems in the prior art that the focusing operation of the flashl...
