Abstract

The utility model relates to an electric torch. The end part of a shell body is provided with a turn button. A shaft lever in the center of the inner part of the turn button is provided with a spiral spring. A plurality of gear wheels can be driven by the shaft lever to drive mutually. A last driving gear wheel can cause a coil curl to rotate by a rotating shaft. The outer part of the coil curl can be induced by a magnet to generate electric power. Thus a bulb of the electric torch can be caused to generate bright light. The electric torch has the advantage that a battery is needless to be used, and the problem of environment pollution which is caused by discarding waste batteries is stopped. The electric torch can provide illumination at a push.

Description

Flashlight

The utility model relates to a kind of flashlight.

Flashlight and daily life have closely bound up relation, and it can be for people in night illumination, and especially just to meet weather bad and when suffering from emergency, its effect is more obvious, can not explain so the practicality of flashlight is not sayed when mountain-climbing.

Yet, with regard to general traditional flashlight, the bulb of this flashlight is when producing light, and the essential electric power of battery that lean on provides, and in flashlight after the electric power of battery exhausts because of use, being about to battery abandons towards the outside taking-up is parallel in flashlight, and refuse battery can cause the problem in the environmental protection after abandoning, for environment and Yan Yihui causes suitable pollution, therefore, the practicality of above-mentioned traditional type flashlight is not enough, and the necessity that is improved is arranged.

Main purpose of the present utility model is to provide a kind of flashlight, and the usefulness of illumination can be provided when urgent, and this flashlight has the advantage that can exempt from battery, and has stifledly cut off refuse battery and cause environmental pollution problems.

The technical scheme that realizes the utility model purpose is: a kind of flashlight, and it comprises:

One cylindrical housing is provided with in an end of this housing and has a turn-button that revolves, is provided with an axostylus axostyle in the turn-button central interior, and a wind spring clockwork spring is set on axostylus axostyle,

Wear a drawing piece on axostylus axostyle, but this drawing piece interlock one gear in the inner round recessed that forms of gear, is formed with unidirectional ratchet in the round recessed outer periphery, unidirectional ratchet can be meshing with each other with the outside of drawing piece,

Another gear of the engageable transmission of gear, but this another gear transmission one couple axle rotates, the transmission but other two gears of this couple axle transmission are meshing with each other, but gear transmission one rotating shaft of this back engaged transmission is rotated, but one group of coil of this rotating shaft interlock rotates, in the housing of coil outside, be provided with magnet, interact to form between magnet and coil, be provided with in the form of a ring insulating trip in the leading section of rotating shaft, be provided with several pieces sheet metals that link to each other with two line ends of described coil respectively in insulating trip, each sheet metal can contact conducting with bulb by two pole pieces.

In above-mentioned flashlight, on described axostylus axostyle, be equipped with the short slot of assembling one wind spring clockwork spring.

The utility model compared with the prior art advantage and good effect is very obvious.By above technical scheme as can be known, the utility model has following advantage at least:

The utility model both had been illumination in emergency circumstances is provided, and exempted to use battery, did not abandon the environmental issue that causes so do not exist because of refuse battery.

Accompanying drawing below in conjunction with an embodiment further specifies concrete structure of the present utility model:

Brief Description Of Drawings:

Fig. 1 is the three-dimensional exploded view of the flashlight of an embodiment of the utility model.

Fig. 2 is the sectional perspective exploded view of Fig. 1.

Fig. 3 be Fig. 1 each parts in conjunction with after cutaway view.

The utility model is a kind of flashlight (shown in Fig. 1,3), can find out overall structure of the present utility model among two figure thus, includes following each element:

One cylindrical housing 10 is provided with in an end of housing 10 and has a turn-button 11 that revolves, is provided with an axostylus axostyle 12 in turn-button 11 central interior, forms a short slot 13 on axostylus axostyle 12, can provide the elasticity when replying thus for the folder wind spring clockwork spring 14 of pulling on short slot 13;

On axostylus axostyle 12, wear one and be Z-shaped drawing piece 20 (as shown in Figure 2), but this drawing piece 20 interlocks one gear 30, the material of this gear 30 can be plastics, be formed with a round recessed 31 in gear 30 inside, outer periphery in round recessed 31 is formed with unidirectional ratchet 32, and this unidirectional ratchet 32 is meshing with each other with the outside of drawing piece 20;

Another gear 40 of gear 30 engaged transmission, this another gear 40 transmission one couple axle 41 again makes it to rotate, the transmission but other two

gears

42,43 of these couple axle 41 transmissions are meshing with each other, but gear 43 transmissions one rotating shaft 50 is rotated, but one group of coil of these rotating shaft 50 interlocks 51 rotates, housing 10 inside in coil 51 outsides are provided with magnet 60, interact to form between this and the coil 51;

Be provided with in the form of a ring insulating trip 70 in the leading section of rotating shaft 50, be provided with several pieces sheet metals 71 that link to each other with two line ends of coil 51 respectively in insulating trip 70, each sheet metal 71 can contact conducting with bulb 80 by two

pole pieces

81,82.

When said structure uses after making up (as Fig. 2, shown in 3), rotatable have a turn-button 11 that revolves, wind spring clockwork spring 14 on the axostylus axostyle 12 is screwed, this moment is because of forming idle running between the unidirectional ratchet 32 of drawing piece 20 and gear 30 inside, that is rotation can make wind spring clockwork spring 14 screw thus, axostylus axostyle 12 is produced to reverse, because of making the mutual engagement of generation between drawing piece 20 and the unidirectional ratchet 32 after the axostylus axostyle 12 generation reverses, also can make another gear 40 of gear 30 engaged transmission, couple axle 41, two gears 42 in addition, 43 etc., make gear 43 drive shafts 50 rotate and make coil 51 rotations, and coil 51 is because of the event of the induction that is subjected to magnet 60, just can produce electric power, electric power then can be delivered on the sheet metal 71, sheet metal 71 is the pole pieces 81 with bulb 80, be in contact with one another between 82, so can make bulb 80 produce light, do not use with the flashlight of battery as a kind of exempting from when good for night or weather, can be for illumination in emergency circumstances be provided, also stifled simultaneously having cut off because of refuse battery caused environmental pollution problems.
