Background technology
The popular feeling that deepens continuously along with energy-conservation theory, the LED illuminating product is used widely, and wherein the LED flashlight relies on its life-span height, brightness decay speed to wait advantage slowly, is accepted by most of people, but, make that the product on the market has a lot of deficiencies because industry is lack of standardization:
1 shock resistance is bad.Generally flashlight is relatively simple for structure, and in the process of using, parts are loosening easily, cause disabler.
2 water proofing properties are bad.Flashlight needs often to use out of doors, if run into the rainy day or call in accidentally in the water, just causes the product short circuit easily, influences service life.
3 heat radiations are bad.The stack shell inside of common product is provided with groove, and the aluminium base that LED will be installed then inserts wherein and since aluminium base directly contact be air, so thermal diffusivity can not guarantee, have a strong impact on the life-span of LED.
The utility model content
In order to overcome above present difficulty, the utility model provides the flashlight of a kind of shockproof, waterproof, perfect heat-dissipating.

The utility model can also take following technical scheme to realize:
Between described lamp holder cover cap and the described lamp holder cabin, between described lens and the described lamp holder cabin, between described lamp holder cabin and the described powerhouse dome, between described powerhouse dome and the described battery flat, between described battery flat and the described switch cabin, be provided with sealing ring between described switch cabin and the described afterbody cover cap;
Described lamp holder cover cap is connected with described lamp holder cabin, described lamp holder cabin is connected with described powerhouse dome, described powerhouse dome is connected with described battery flat, described battery flat is connected with described switch cabin, described switch cabin is connected with described afterbody cover cap, and above connection all is threaded.
The utility model advantage and beneficial effect are embodied in the following aspects:
1 the utility model stack shell is all to be threaded, and inside is all fixed with screw, and structure is firm, and shockproof properties is good.
2LED light decay speed is slow, and the life-span is long, has more practicality than common torch.
Each parts of 3 stack shells are provided with sealing ring, and water resistance is good.
4 are provided with the lamp holder cabin in stack shell inside, and aluminium base is screwed on the lamp holder cabin, realize that LED dispels the heat to greatest extent.
The specific embodiment
As Figure 1-3: the 1st, lamp holder cover cap, the 2nd, lamp holder cabin, the 3rd, screw, the 4th, powerhouse dome, the 5th, PCBA, the 6th, battery flat, the 7th, switch cabin, the 8th, afterbody cover cap, the 9th, rubber cover cap, the 10th, sealing ring, the 11st, switch, the 12nd, sealing ring, the 13rd, battery, the 14th, sealing ring, the 15th, sealing ring, the 16th, aluminium base, the 17th, sealing ring, the 18th, sealing ring, the 19th, lens, the 20th, LED.
The utility model comprises LED20, aluminium base 16, PCBA5, stack shell, battery 13, and LED20 is fixed on the aluminium base 16, and aluminium base 16, PCBA5 and battery 13 are placed on the inside of stack shell.
Stack shell comprises lamp holder cover cap 1, lamp holder cabin 2, powerhouse dome 4, battery flat 6, switch cabin 7, afterbody cover cap 8, lamp holder cover cap 1 is connected with lamp holder cabin 2, lamp holder cabin 2 is connected with powerhouse dome 4, powerhouse dome 4 is connected with battery flat 6, battery flat 6 is connected with switch cabin 7, switch cabin 7 is connected with afterbody cover cap 8, and above connection all is threaded.
Aluminium base 16 usefulness screws 3 are fixed on the inside in lamp holder cabin 2, aluminium base 16 and lamp holder cabin 2 are closely cooperated, realize the heat radiation to greatest extent of LED20, be provided with lens 19 between lamp holder cover cap 1 and the aluminium base 16, PCBA5 is arranged in the powerhouse dome 4, is used for LED20 is controlled, and battery 20 is placed in the battery flat 6, for product provides electric energy, be provided with switch 11 and rubber cover cap 9 between switch cabin 7 and the afterbody cover cap 8.
Between lamp holder cover cap 1 and the lamp holder cabin 2, between lens 19 and the lamp holder cabin 2, between lamp holder cabin 2 and the powerhouse dome 4, between powerhouse dome 4 and the battery flat 6, between battery flat 6 and the switch cabin 7, be provided with sealing ring between switch cabin 7 and the afterbody cover cap 8, can realize the utility model favorable waterproof property.
Assembling process of the present utility model: at first PCBA5 is placed into powerhouse dome 4, then powerhouse dome 4 and lamp holder cabin 2 are threaded, interface is placed sealing ring 15, LED10 is welded on the aluminium base 16 then, and aluminium base 16 is fixed on the inside in lamp holder cabin 2 with screw 3, simultaneously, screw 3 is also fixing with lamp holder cabin 2 and powerhouse dome 4, then lens 19 are put into 2 inside, lamp holder cabin, and at interface placement sealing ring 18, placement lamp holder cover cap 1 on lens 19 then, lamp holder cover cap 1 and lamp holder cabin 2 are threaded, its interface is placed sealing ring 17 simultaneously, then switch 11 is placed into the inside in switch cabin 7, again rubber cover cap 9 is passed afterbody cover cap 8, then afterbody cover cap 8 and switch cabin 7 are threaded, interface is placed sealing ring 10, then battery 13 is put into battery flat 6 inside, then battery flat 6 and powerhouse dome 4 are threaded, interface is placed sealing ring 14, at last switch cabin 7 and battery flat 6 are threaded, interface is placed sealing ring 12, has so just finished assembling of the present utility model.
Utilize technical scheme described in the utility model, or those skilled in the art designing the similar techniques scheme under the inspiration of technical solutions of the utility model, and reach above-mentioned technique effect, all is to fall into protection domain of the present utility model.
