Abstract

The utility model discloses an electric torch without batteries, comprising a gun type shell body, an electric torch head, a reflecting mirror, and an electric bead. The electric torch without batteries is characterized in that a set of worm gear and worm mechanism, a bull gear for driving the worm gear to rotate, and a trigger rod are arranged inside the shell body. The left end of the worm is fixed with a rotor which is made of magnetic materials. A stator coil is arranged on the shell body corresponding to the position of the rotor. When the electric torch without batteries is used, as long as the trigger is wrenched by hand, the rotor is driven by the worm to rotate. The electric bead which is connected with the stator coil emits bright light meanwhile.

Description

No battery flashlight

The utility model belongs to portable lighting device, relates to a kind of manually to be the no battery flashlight of power source.

Torch is article commonly used in a kind of people's life, and its type also has a variety of.But existing torch has a lot of shortcomings.Because adopting battery is power source, if for a long time need not, battery can automatic leakage of electricity.Even some Chargeable electric torches also are at first electric energy to be converted into chemical energy to store, again chemical energy is converted into electric energy again during use, make small electric bulb luminous

The purpose of this utility model is according to mechanical electricity generating principle, and a kind of frame for movement is provided, without battery, manually being power source, the collection practicality and recreational be the flashlight of one.

The utility model has the housing of an outer image pistol, and a cover worm gear, worm gearing are installed in housing; A gear wheel and a plate machine bar that is used for driving worm gear also is installed on housing; At the worm gear left end rotor is installed, stator coil is installed at housing corresponding position with it; Speculum, tube head and small electric bulb are installed in the housing left end.

The utility model has the advantages that employing frame for movement,, as power source, can generate electricity at any time that practicality is promptly arranged, have recreationally again, be particularly suitable for field work and the interim occasion of using, can satisfy the teen-age active and psychology of hunting for novelty with manually without battery.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view of the utility model Fig. 1.

The utility model has a housing 4, for ease of installing, housing can adopt two buckled.In enclosure interior a worm gear 8 and one and its engaged worm 7 are installed, a ratchet 14 is arranged on worm-wheel shaft, adopt ratchet, detent mechanism to be connected between worm-wheel shaft and the worm gear.On worm-wheel shaft, also be fixed with a pinion 9, this pinion 9 and gear wheel 10 engagements, said gear wheel 10 is fixed in the rotating shaft 13, and rotating shaft 13 is installed on the housing 4.An intrinsic trigger rod 12 in rotating shaft 13 is equivalent to the plate machine of pistol.Back-moving spring 11 two ends are separately fixed on gear wheel 10 and the housing.At the worm screw left end rotor 6 of being made by magnetic material is installed, on housing, a stator coil 5 is arranged with rotor 6 corresponding fixed-site.At the housing left end seat board is arranged, on seat board, be connected with speculum 2 and small electric bulb 3.Said small electric bulb 3 is connected with the line that stator coil is drawn.Tube 1 links together by screw thread and housing 4.

During use,, will drive rotor rotation by the worm gear in the housing, worm mechanism as long as collude plate machine 12 with a finger.According to electrical principles, can send electric current by stator coil and make small electric bulb luminous.If collude the plate machine continuously, rotor will quicken to rotate, and small electric bulb will be luminous continuously.

Claims

1, a kind of flashlight without battery comprises pistol type housing, tube head, speculum, small electric bulb, it is characterized in that: a cover worm gear, worm mechanism are installed in housing; In housing, also have one to be used for driving gear wheel and the trigger rod that worm gear rotates; Be fixed with a rotor of making by magnetic material at the worm screw left end, on housing, a stator coil be installed with the corresponding position of this rotor.

2, flashlight according to claim 1 is characterized in that: adopt ratchet, pawl structures between worm gear and the worm-wheel shaft.

3, flashlight according to claim 1 is characterized in that: a pinion is installed on worm-wheel shaft.
