Abstract

The utility model relates to a focusing flashlight which comprises a cylinder body (1), a lamp holder (6), a luminous body (7) and a focusing lens (8) which is fixedly arranged on the lamp holder (6). The focusing flashlight is characterized by further comprising a fixed ring (2), a lamp socket (4), a sliding ring (5) and a dimming ring (3), a first end of the fixed ring is arranged inside the cylinder body (1) in a threaded close-fitting mode, a second end of the fixed ring extends out of the cylinder body, the lamp socket (4) is arranged inside the second end of the fixed ring in a threaded close-fitting mode, the luminous body (7) is arranged on the lamp socket (4), the sliding ring (5) is movably sleeved outside the fixed ring, the lamp holder (6) is arranged outside a second end of the sliding ring (5) in a threaded close-fitting mode, and the dimming ring (3) is sleeved outside the sliding ring (5) in a sliding mode through threads and is also sleeved outside the lamp holder (6). Compared with the prior art, the focusing flashlight has the advantages that the fixed ring, the lamp socket and the sliding ring are arranged, the mutual matching relation among the fixed ring, the lamp socket and the sliding ring is used, when the dimming ring rotates, the entirety including the sliding ring, the lamp holder and the lens slides simultaneously as well, the flashlight achieves a focusing function, structure is novel, and focusing and using are convenient.

Description

A kind of 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, first end screw thread close-fitting is arranged in the stack shell, and the second end 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 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 by screw thread, also is set in outside the lamp holder simultaneously.

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.

Described lamp holder also is arranged with transparent ring outward, and transparent ring is positioned at light modulation circle inside equally, and the position of this transparent ring is when satisfying the light modulation circle and turning to a certain degree, and transparent ring exposes to outside the light modulation circle.Transparent ring can play warning function, allows the user not be rotated further the light modulation circle again.

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.

The specific embodiment

Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.

Focus flashlight as depicted in figs. 1 and 2 comprises stack shell 1, encloses 2 surely, light modulation circle 3, lamp socket 4, sliding ring 5, lamp holder 6, illuminator 7, condenser lens 8 and transparent ring 9, wherein, condenser lens 8 is fixed on the lamp holder 6, transparent ring 9 screw thread close-fittings are outside lamp holder 6, illuminator 7 is fixed on the lamp socket 4, encloses 2 first end screw thread close-fitting surely and is arranged in the stack shell 1, and the second end stretches out outside the stack shell; Lamp socket 4 screw thread close-fittings are arranged on to be decided in the circle the second end; Sliding ring 5 is movably set in to be decided outside the circle, and lamp holder 6 screw thread close-fittings are outside sliding ring 5 the second ends; Light modulation circle 3 is crossed screw threads and is slidingly located in outside sliding ring 5 first ends, also is set in outside the lamp holder 6 simultaneously, and transparent ring 9 is positioned at light modulation circle 3 inside equally, and the position of this transparent ring 9 is when satisfying light modulation circle 3 and turning to a certain degree, and transparent ring 9 exposes to outside the light modulation circle 3.Described 2 outer walls that enclose surely are provided with chute 21, and described sliding ring 5 inwalls are provided with slide rail 51, and described slide rail 51 is slidingly arranged in the described chute 21, referring to shown in Figure 3.

Claims
