Abstract
The utility model discloses a rotary focusing device used for an LED flashlight. The rotary focusing device comprises a dimming ring, a fixing base, a lamp base, a dimming lining and a steel ball and spring assembly. The dimming ring and the dimming lining are connected in a close-fit mode, a head ring fixes a lens to the top end of the fixing base through threads, the steel ball and spring assembly is installed between the fixing base and the dimming ring, the dimming ring is meshed with a steel ball of the steel ball and spring assembly through a tooth groove, the lamp base is fixed in the dimming ring through a pin, an inclined clamping groove used for positioning the pin is formed in the dimming ring, and the fixing base is connected with a base through threads. The dimming lining is rotated, and the dimming ring drives the lamp base to move vertically through the internal inclined clamping groove and the pin, so that the linear distance between the lamp base and the lens is adjusted to achieve focusing. The rotary focusing device has the advantages of being practical, rapid to assemble, low in production cost, simple in structure, convenient to use and adjust and long in service life.
Description
Technical field
The utility model relates to a kind of torch focus control, particularly the rotary focus control of a kind of LED flashlight.
Background technology
