Abstract
The utility model relates to a displacement zooming water-stop structure of a flashlight. A movable sleeve and a lampshade are sleeved on a body of the flashlight, a sealing ring is disposed in the movable sleeve, and the lampshade is arranged between the movable sleeve and the body of the flashlight in a penetrating manner and is mutually combined with the movable sleeve in a threaded manner. When in use, the lampshade can rotate anticlockwise, so that the edge of the lampshade is separated from the sealing ring so as to drive the movable sleeve, the sealing ring and the lampshade to move along with the body of the flashlight, and the effect of rapidly adjusting focal distance can be realized. Alternatively, the lampshade rotates clockwise, so that the edge of the lampshade presses the sealing ring so as to force the sealing ring to deform and be adhered onto the outer wall surface of the body of the flashlight, and the purpose of fixing the focal distance between a lens and a light emitting component and the effect of stopping water can be achieved.

The specific embodiment
Below cooperate preferred embodiment graphic and that the utility model is designed, further setting forth the utility model is to reach the technological means that predetermined purpose is taked.
Shown in Fig. 1 and 2, the displacement zoom water sealing structure of flashlight of the present utility model comprises a flashlight body 10, a moving sleeve 20, a sealing ring 30 and a lampshade 40, wherein:
One front end place of flashlight body 10 is provided with a luminescence component 11, these flashlight body 10 inside can be provided with battery pack to provide this luminescence component 11 required electric power, in addition, be provided with a flange 12 near the front end place on the outside wall surface of this flashlight body 10, preferably, this flange 12 is around the outside wall surface setting of this flashlight body 10;
Cooperation is referring to shown in Figure 3, moving sleeve 20 is sheathed on this flashlight body 10, form one first limiting section 21 and an internal thread part 22 on this moving sleeve 20, this first limiting section 21 is located on the internal face of this moving sleeve 20 near the middle section, preferably, this first limiting section 21 is around the internal face setting of this moving sleeve 20, and fits in the outside wall surface of this flashlight body 10, and this internal thread part 22 is located on corresponding front end place on the internal face of this moving sleeve 20;
In the specific embodiment of the present utility model, the luminescence component 11 of above-mentioned flashlight body 10 is a light emitting diode (Light Emitting Diode, LED) module, wherein because led module can produce a large amount of heats in use, so the material that this moving sleeve 20 can be used tool great heat radiation effects such as metal is made, and on the outside wall surface of this moving sleeve 20, further be provided with a radiating part 23, this radiating part 23 can be the annular groove 231 that a plurality of spacer rings are located at the outside wall surface of this moving sleeve 20, make 231 of two adjacent annular grooves form the fin shape, improve the radiating effect of this moving sleeve 20 by this;
Lampshade 40 is a transparent or semitransparent housing, its front end sealing, the rear end is the front end that opening is sheathed on this flashlight body 10, and be arranged between this flashlight body 10 and the moving sleeve 20, these lampshade 40 inside are provided with lens 41, and the internal face of this lampshade 40 is provided with one second limiting section 42, preferably, this second limiting section 42 is around the internal face setting of this lampshade 40, be equipped with an external thread part 43 near rear end in addition on the outside wall surface of this lampshade 40, this external thread part 43 mutually combines with the internal thread part 22 of this moving sleeve 20.
Referring to shown in Figure 3, flashlight of the present utility model in use, can be earlier by rotating counterclockwise this lampshade 40, make the ora terminalis of these lampshade 40 rear ends break away from sealing ring 30, at this moment, the user can drive this moving sleeve 20, sealing ring 30 and lampshade 40 together move along this flashlight body 10, the lens 41 of this lampshade 40 of rapid adjustment and the distance between this luminescence component 11, reach the effect of optically focused or floodlight, wherein, cooperation is referring to shown in Figure 4, but and the flange 12 of this flashlight body 10 of mat be resisted against sealing ring 30, perhaps, cooperation is referring to shown in Figure 5, this flange 12 of mat is resisted against second limiting section 42 of this lampshade 40, is used as limiting this moving sleeve 20, the extreme position that sealing ring 30 and lampshade 40 can move relative to this flashlight body 10, and 40 designs that combine with screw thread of this moving sleeve 20 and lampshade.
Again, referring to shown in Figure 4, after the distance that roughly mixes up lens 41 and luminescence component 11, just can clockwise rotate this lampshade 40,, force 30 distortion of sealing ring and be close to the outside wall surface of this flashlight body 10 up to this lampshade 40 rear end ora terminalis compressing sealing rings 30, at this moment, this moving sleeve 20 can't move along this flashlight body 10 with lampshade 40 again, simultaneously, because the inside of this lampshade 40 forms the space of a sealing sealing.
In addition, because this lampshade 40 shines simultaneously at straight line as being transparent material, part light can go out to produce the sidelight effect by side-irradiation, and reaches when out encamping when having a power failure at home, can work as the use of Emergency Light lamp and camping lamp.When lampshade 40 can use as emergency lamp for trnaslucent materials (as: redness, yellow etc. all can);
Moreover, because these lens 41 are closed in this lampshade 40, after the distance of process adjustment earlier of the light of luminescence component 11 and lens 41 produces the effect of optically focused or floodlight, again towards the flashlight external irradiation, therefore can be because of the refractive index difference of water even in water, use also not, and influence the effect of the optically focused or the floodlight of these lens.
