Flashlight

Technical field

The utility model relates to a kind of flashlight, especially has the flashlight of improvement light-emitting device.

Background technology

At present common flashlight light-emitting device is simple, directly the lamp pearl is contained in the cylindrical shell luminously, adjusts and focuses on inconveniently, and also is unfavorable for maintenance after breaking down.

Summary of the invention

In order to overcome the above-mentioned defective that exists in the prior art, the technical problems to be solved in the utility model provides a kind of flashlight, and it is adjusted and focuses on conveniently, and is simple in structure, is easy to installation and maintenance.

The utility model is achieved by the following technical solution: a kind of flashlight, the light-emitting device that it comprises cylindrical shell and is positioned at cylindrical shell, described light-emitting device is electrically connected with cylindrical shell, battery, it is characterized in that, described light-emitting device comprises lamp and the lamp socket of described lamp is installed, described lamp socket removably is connected with cylindrical shell, and can vertically moving along cylindrical shell.

Preferably, described lamp socket is provided with the threaded connector that it is moved with respect to cylindrical shell.

Further, described threaded connector is the retainer ring nut that is enclosed within lamp socket one end, and the other end of described lamp socket is with power spring, and the two ends of described power spring are described lamp socket of butt and cylindrical shell respectively.

Perhaps, described threaded connector is integrally formed on the peripheral surface of lamp socket.

Compared with prior art, because light-emitting device and cylindrical shell can relatively move, and preferably adopt screw connection structure, so make focusing, assembling and the convenience easy to maintenance of this light-emitting device.

The specific embodiment

Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.

As shown in Figure 1 to Figure 3, a kind of flashlight comprises cylindrical shell 1, tail-hood 2, battery (group) 3, switch 4 and light-emitting device 5.Light-emitting device 5 comprises lamp (pearl) 51, lamp (pearl) seat 52, power spring 53, retainer ring nut 54, conductor wire 55, anodal shell fragment 56 and negative pole shell fragment 57.Lamp pearl 51 is inserted in the centre of lamp bulb seat 52, in two apertures in the middle of lamp bulb seat 52 anodal shell fragment 56 and negative pole shell fragment 57 are housed respectively, two pin of lamp pearl 51 communicate with the anodal shell fragment 56 and the negative pole shell fragment 57 that are contained in lamp bulb seat 52 centres respectively, anodal shell fragment 56 communicates with switch 4 by conductor wire 55, and switch 4 communicates by conductor wire 43 and the conduction nail 42 that is contained in the middle of the liner 41 equally at the other end, battery 3 positive poles directly communicate with conduction nail 42, one end of negative pole shell fragment 57 is bent on the excircle of lamp bulb seat 52, be with power spring 53 in the above, when lamp bulb seat 52 is contained in the cylindrical shell 1 by retainer ring nut 54, one end of power spring 53 withstands on the interior end face 11A of cylindrical shell, the other end withstands lamp bulb seat 52, like this, negative pole shell fragment 57 is by power spring 53 and cylindrical shell 1 UNICOM, simultaneously, when lamp pearl 51 luminous point height errors will be adjusted focusing, can regulate retainer ring nut 54, make lamp bulb seat 52 bands be contained in inner lamp pearl 51 and under the effect of power spring 53, move up and down the purpose that reaches adjustment focusing.Because of cylindrical shell 1 and light-emitting device have adopted screw connection structure, so convenient disassembly, assembling is also easily simple.

Shown in Fig. 4,5,6, in a second embodiment, light-emitting device 5 comprises that lamp is that light emitting diode 51, lamp socket are core retainer plate 52, drive integrated circult piece 53, have first fiberboard 54 and second fiberboard 55 of copper foil circuit, drive integrated circult piece 53 is installed in the inside of core retainer plate 52, light emitting diode 51 is fixed on the middle boss of core retainer plate 52 by heat-conducting glue, be communicated with drive integrated circult piece 53 by first fiberboard 54, drive integrated circult piece 53 is communicated with battery pack 3 by second fiberboard 55.Light emitting diode 51 fuses with core retainer plate 53, is formed with screw thread on the peripheral surface of core retainer plate 53, adopts with cylindrical shell to be threaded, and the heat of its luminous generation will conduct by core retainer plate 52.

According to flashlight of the present utility model, core retainer plate 52 in the light-emitting device 5 not only plays thermolysis, also light emitting diode 51, drive integrated circult piece 53 and first fiberboard 54, second fiberboard 55 are unified into the major part of an integral body, electric action is also arranged simultaneously, form the loop with flashlight cylinder, simple in structure.Adopt screw connection structure with cylindrical shell, make its installation and maintenance easier.

Preferred forms of the present utility model has only been described above; those skilled in the art will recognize that; protection domain of the present utility model is not limited to above-mentioned concrete structure, as long as the lamp socket 52 of flashlight can be dismantled and can focus with respect to vertically moving of cylindrical shell 1.
