Abstract
The utility model discloses a headlight convenient for adjusting focal length, which comprises a battery box, wherein the battery box is provided with a center pole, a bulb is arranged in the center pole, a joint which can be front and back moved is sleeved on the center pole, and the front end of the joint and a head ring provided with a built-in convex lens are spirally connected. The bulb is anLED. The headlight can change the distance between the convex lens and the bulb in the head ring only through forwards and backwards moving the joint along the center rod, thereby achieving the adjustment of focal length, and the headlight has extremely simple structure and more convenient use.
Description
Technical field:
The utility model relates to technical field of lamps, especially relates to a kind of head lamp that uses in head of wearing.
Background technology:
When operation was located in people's exploration in the open air or tunnel, tunnel, down-hole etc., head lamp was an essential product, and for adapting to different lighting requirements, head lamp need be focused.Present head lamp focus adjustment structure is similar to flashlight, needs the rotary head circle to realize, this focus adjustment structure is comparatively complicated, and has a lot of inconvenience on using.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and a kind of head lamp of conveniently focusing is provided that it has characteristics simple in structure, that use is more convenient.
For achieving the above object, head lamp of conveniently focusing of the present utility model includes a battery case, and battery case has a center-pole, is provided with bulb in the center-pole, be arranged with a joint that can move forward and backward on the described center-pole, the joint front end is threaded with the head circle of built-in convex lens sheet.
Described bulb is LED.
The beneficial effects of the utility model are: it only needs joint is moved forward and backward the convex lens sheet that can change in the head circle and the distance between the bulb along center-pole, thereby realizes the adjusting of focal length, and structure is very simple, uses also more convenient.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is a decomposition texture schematic diagram of the present utility model.
The specific embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in accompanying drawing 1 and the accompanying drawing 2: head lamp of conveniently focusing of the present utility model includes the battery case 10 of a band frenulum 11, and battery case 10 has a center-pole 20, is provided with LED bulb 21 in the center-pole 20.Be arranged with a joint that can move forward and backward 30 on the center-pole 20, joint 30 front ends are threaded with the head circle 40 of built-in convex lens sheet 41.
The utility model only needs joint 30 is moved forward and backward along center-pole 20, when joint 30 moves forward and backward in use, the head circle 40 that is threaded with it also moves forward and backward, thereby change the interior convex lens sheet 41 of head circle and the distance of LED bulb 21, reach the purpose that changes focal length, very convenient.
