Abstract

The utility model relates to a focusing flashlight which comprises a cylinder body (1), a flashlight head (6), an illuminant body (7) and a focusing lens (8) which is fixed on the flashlight head (6). The focusing flashlight is characterized in that the focusing flashlight further comprises a fixed ring (2), a sliding ring (5) and a dimming ring (3), wherein a first end portion of the fixed ring is arranged in the cylinder body (1) in a threaded close-fitting mode, a second end portion of the fixed ring extends out of the cylinder body, the sliding ring (5) is movably sleeved outside the fixed ring, the flashlight head (6) is arranged outside the second end portion of the sliding ring (5) in a threaded close-fitting mode, the dimming ring (3) is sleeved outside the first end portion of the sliding ring (5) in a threaded sliding mode, the front end portion of the dimming ring (3) is inserted into the flashlight head (6), and the outer wall of the rear end portion of the dimming ring (3) is exposed outside the flashlight head (6) and the cylinder body (1). Compared with the prior art, the focusing flashlight has the advantages that through arrangement of the fixed ring, a flashlight seat and the sliding ring and mutual matching relationships among the fixed ring, the flashlight seat and the sliding ring, when the dimming ring rotates, a whole which comprises the sliding ring, the flashlight head and the lens slides at the same time, and therefore the flashlight achieves a focusing function and is novel in structure and convenient to focus and use.

Description

Focus flashlight

Technical field

The utility model relates to a kind of focus flashlight.

Background technology

In the prior art, the flashlight product of Xiao Shouing is quite a lot of on the market, and style and function also are not quite similar.These flashlights generally can both change illumination distances and optically focused degree by adjusting focal length, its essential structure and focusing principle are: condenser lens is fixed on the bulb socket, illuminator (being generally osram lamp or light emitting diode) is fixed in the lamp body, its bulb socket of turn is with the distance between change condenser lens and the illuminator, and then the adjustment effect of the remote illumination of realization (optically focused, high brightness) and closely throw light on (floodlight, large tracts of land).But, in the focusing process of this class flashlight, focusing on the position and run into external object easily, the focusing gear of setting will change so originally, uses not too inconvenient.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of novel structure, the same focus flashlight that can realize the focusing purpose at above-mentioned prior art.

The utility model solves the problems of the technologies described above the technical scheme that adopts: this focus flashlight, comprise stack shell, and lamp holder, illuminator is fixed on the condenser lens on the lamp holder, it is characterized in that: also comprise

Fixed circle, the first end screw thread close-fitting of fixed circle is arranged in the stack shell, and the second end of fixed circle stretches out outside the stack shell;

Lamp socket, screw thread close-fitting are arranged on to be decided in the circle the second end, and illuminator is arranged on this lamp socket;

Sliding ring is movably set in and decides outside the circle, and sliding ring has first end and the second end, and described cap screw thread close-fitting is outside the sliding ring the second end;

The light modulation circle is slidingly located in outside the sliding ring first end by screw thread, and the leading section of light modulation circle stretches into lamp holder inside, and the rearward end outer wall of light modulation circle exposes to outside lamp holder and the stack shell.

When the light modulation circle rotated, the integral body that comprises sliding ring, lamp holder and lens three was also slided simultaneously, made flashlight realize the focusing function.

Describedly decide ring outer wall and be provided with chute, described sliding ring inwall is provided with slide rail, and described slide rail is slidingly arranged in the described chute, and when this matching relationship rotated the light modulation circle, sliding ring can be done linear slide along Ding Quan.

Compared with prior art, advantage of the present utility model is: decide circle, lamp socket, sliding ring by arranging, and by the relation of cooperatively interacting between them, when the light modulation circle rotates, the integral body that comprises sliding ring, lamp holder and lens three is also slided simultaneously, make flashlight realize the focusing function, novel structure, it is easy to use to focus.
