Abstract

The invention discloses an electric torch which is power-supplied by batteries and has two using modes. The electric torch comprises a barrel body, a lamp holder, a bulb, a lampshade and a light-reflecting cup, wherein the bulb is installed at the front end of the barrel body by the lamp holder, and a slide sleeve capable of sliding along the axis of the barrel body is sleeved at the front end of the barrel body; the circumferential wall of the back end of the lampshade is connected together with the front end of the slide sleeve, the front wall and the circumferential wall of the lampshade are nonopaque; the light-reflecting cup is fixed on the inner side of the lampshade, an opening at the front end of the light-reflecting cup is just opposite to the front wall of the lampshade, and reflecting layers both cover the inner wall surface and the outer wall surface of the light-reflecting cup; and the slide sleeve slides between an extended position and a retracted position, wherein in the extended position, the light-reflecting cup and the bulb are mutually spaced, a majority of light rays emitted by the bulb transmit the circumferential wall of the lampshade to illuminate close-distance zones, and in the retracted position, at least part of the bulb passes through the opening at the back end of the light-reflecting cup, and the light rays emitted by bulb transmit the front wall of the lampshade to supply remote directional illumination. The electric torch disclosed in the invention has the advantages of simple and reasonable structure, easiness in assembly and convenience in use.

Description

Flashlight
(1) technical field
The invention discloses a kind of flashlights battery-powered, that two kinds of use patterns are arranged.Wherein a kind of pattern provides the common flashlight mode of the remote illumination of directional beam, and another kind of pattern provides the ordinary lamp and lantern mode of divergent rays nearby region illumination.
(2) background technology
Existing flashlight can only provide the directional beam of focusing to throw light at a distance, can't provide divergent rays to carry out the nearby region illumination as ordinary lamp and lantern.
(3) summary of the invention
The object of the present invention is to provide a kind of two kinds of flashlights that use pattern that have.
For achieving the above object, the present invention is by the following technical solutions:
A kind of flashlight, comprise a cylindrical shell, one lamp socket, one bulb, one lampshade and a reflector, bulb is installed on barrel front end by lamp socket, it is characterized in that: barrel front end is arranged with can be along the sliding sleeve of tubular axis slip, the perisporium of lampshade rear end and sliding sleeve front end are linked together, the antetheca of lampshade and perisporium all are printing opacities, reflector is fixed on the lampshade inboard, the opening of reflector front end is over against the lampshade antetheca, the internal face of reflector and outside wall surface all are coated with the reflecting layer, slide between an extended position and the retracted position and slide, on extended position, reflector and bulb space, the perisporium that most of light that bulb sends sees through lampshade throws light on for nearby region, on retracted position, bulb to small part is passed the opening of reflector rear end, and the light that bulb sends sees through the antetheca of lampshade for remote directional lighting.
Flashlight of the present invention can utilize the reflecting layer of reflector internal face (parabola) to focus on directional beam is provided, and reaches the effect of remote illumination.This flashlight also can utilize the reflecting layer of reflector outside wall surface that divergent rays is provided, and reaches the effect of nearby region illumination.
Technique scheme can also be further improved by following technical measures.
The antetheca of lampshade is transparent, and the perisporium of lampshade is translucent.The perisporium of lampshade has frosting and the shape that is translucent.Bulb is a light emitting diode.When closely throwing light on, light reflects through the reflecting layer of reflector outside wall surface earlier, utilizes the frosting scattering of lampshade perisporium again, reaches the effect of even illumination, avoids flashlight irradiation center, dead ahead that shadow is arranged.
Reflector front end and lampshade inboard are gluedd joint or are welded together.
The perisporium of lampshade rear end is provided with external screw thread, and the inwall of sliding sleeve front end is provided with internal thread, and lampshade and sliding sleeve spin together.
The outer wall of cylindrical shell is provided with the outside radial flange that offsets with the sliding sleeve rear end, lamp socket screws at the barrel front end opening part, the outer wall of lamp socket front end is provided with outside radial flange, the radial flange that slides on the extended position with lamp socket offsets, and the radial flange that slides on the retracted position with cylindrical shell offsets.When assembling this flashlight, earlier sliding sleeve is enclosed within barrel front end, again lamp socket is screwed on cylindrical shell, at last lampshade is screwed on sliding sleeve.
The outer wall of lamp socket rear end is provided with external screw thread, and the inwall of barrel front end is provided with internal thread and screws for lamp socket.
The outer wall of cylindrical shell is provided with annular groove, and the C shape elasticity card of outside expansion is housed in the annular groove, and C shape elasticity card and sliding sleeve inwall offset to hinder to produce certain damping and slide over slippage on the cylindrical shell.The damping that the elasticity card produces can prevent to slide over slippage arbitrarily on the cylindrical shell.
More than each technical measures can select a use, use also capable of being combined.
Flashlight structure advantages of simple disclosed by the invention, assembling is easily, and is easy to use, and directional lighting also can the nearby region illumination at a distance.

Fig. 2 is the three-dimensional exploded view of flashlight of the present invention;
Fig. 3 is the cutaway view of flashlight of the present invention when directional beam throws light on;
Fig. 4 is the cutaway view of flashlight of the present invention when divergent rays is thrown light on.
(5) specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.Be necessary to be pointed out that at this following embodiment only is used for the present invention is further specified; can not be interpreted as limiting the scope of the invention, the those of ordinary skill in this field can essence according to the present invention be made some nonessential improvement and adjustment to following embodiment.
