Description

The portable lamp focus control

Technical field

The utility model relates to the focus control of a kind of portable lamp, particularly a kind of portable lamp.

Background technology

The portable lamp of flashlight, Hand-held Emergency Lamp, ore deposit cap lamp and so on is battery-powered, general all is to use in the mode that moves, the cap part of known portable lamp generally is made up of bulb and concave mirror, the superimposed light light that makes of the reflector focus of bulb and concave mirror is integrated a branch of, it is that bulb and concave mirror are neither removable that one class is wherein arranged, light collecting and distributing unadjustable.It is collecting and distributing that another kind of portable lamp can be regulated light, moves by concave mirror and achieve the goal, and needs the turn concave mirror that it is moved axially with respect to bulb when still operating, and this mode shortcoming is a troublesome poeration, and focusing speed is slow and focus inaccurate.

Summary of the invention

At the deficiency that the prior art scheme exists, the purpose of this utility model is to provide a kind of portable lamp of easy and simple to handle, simple in structure, light light adjustable focus.

The utility model is achieved in that a kind of portable lamp of adjustable focus, comprise housing, bulb, lamp socket, concave mirror, it is characterized in that being provided with in the housing supporting member support lamp socket, one end of lamp socket connects bulb, the lamp socket upper surface is provided with groove, is provided with a gears engaged groove in the housing, and the gear rotation drives lamp socket by groove and moves axially with respect to concave mirror, opening is arranged on the housing, and a gear part has been revealed outside the housing.

Described lamp socket two side is provided with keeper, and keeper is provided with locating part.

The beneficial effects of the utility model: move lamp socket owing to adopt the gear rotation to drive the lamp socket that is provided with groove, adjust easily light light collecting and distributing in, can not exist lamp socket to move the problem of difficulty, it is flexible to regulate the light boundling, simple in structure, production cost is low, and is easy to use.
