Description

A kind of zoom flashlight

Technical field

The present invention relates to a kind of flashlight, particularly a kind of zoom flashlight.

Background technology

At home, in the entertainment place, flashlight is often used as a kind of movable light source yard in one's power.Common flashlight generally includes the body and the cylinder that is used for holding battery that include incandescent lamp.In the body parabolic lens or parabolic type reflector are installed, the filament of bulb is arranged in the focus of minute surface, and the front end of this body is installed a glass plate.Form certain elevation angle between the outward flange of the filament of bulb and parabolic type reflector, the light that this bulb sends, all be radiated on the parabolic type reflector greater than the light elevation angle and irradiation backward, be reflected into parallel reverberation by the parabolic type reflector then, this part light is useful beam.All the other light less than the elevation angle directly outwards penetrate from glass plate, this part light in most of the cases all is to have wasted, and the position of the bulb of this flashlight and parabolic type reflector is all fixed, can not regulate their distance, so the flashlight of the zoom more demand of people that can better satisfy.And the zoom flashlight majority on the market is to add a zoom system, pancreatic system between the light supply apparatus of flashlight and light-emitting window, the hot spot that light supply apparatus is produced can change its rising angle, thereby makes flashlight can adjust its facula area size and brightness to satisfy people's multiple demand.Yet existing zoom system, pancreatic system complex structure and parts are more, and ease of use is relatively poor, thereby need a kind of simple in structure and can realize the flashlight of zoom purpose.

Summary of the invention

The object of the present invention is to provide a kind of zoom flashlight simple in structure.

For achieving the above object, the present invention adopts following technical scheme: a kind of zoom flashlight, it comprises that group is established the camera lens shell of eyeglass, turn-taked, Head and Neck, lamp socket and inner the body of battery pack can be installed, lamp socket is assembled in the Head and Neck, one end of Head and Neck assembles the other end mutually with the camera lens shell and body is assembled mutually, further be provided with on the described Head and Neck and the balladeur train of turn-taking and matching, described balladeur train outer wall is provided with guide rail, and inwall is provided with guide groove; Described Head and Neck is provided with embeded slot, the described inwall of turn-taking is provided with the depressed part that matches with carriage rail, described lamp socket top is installed with the LED lamp, and lamp socket is assembled in the Head and Neck by a guide pillar, and described guide pillar passes embeded slot and its end is contained in the balladeur train guide groove.

Compared with prior art, the present invention has following beneficial effect: by making guide pillar on the lamp socket slide in the balladeur train guide groove to adjust distance between light source and the camera lens to realize the purpose of zoom in that helical guide groove is set on the balladeur train, simple in structure effective.
