Abstract

The utility model discloses an electric torch with manual power generation function, which comprises a shell and the front end of the shell is provided with a light reflecting bowl and a bulb. A handle with a cambered rack bar of internal teeth is arranged in the shell, and a handle return spring is arranged on the handle. The cambered rack bar of internal teeth on the handle is engaged with a duplicate gear and also a small gear which is engaged with a big gear of the duplicate gear, wherein the small gear is provided with a ratchet pawl. A ratchet of an internal hole of a permanent magnetic rotor of a generator is connected with the ratchet pawl of the small gear. The utility model is characterized in that a circuit board of a bridge rectifier circuit which is composed of a diode is also arranged; the bulb is a light emitting diode; a resistor is in series connected between the diode of the bridge rectifier circuit and the light emitting diode. The utility model has the advantages of high brightness, good light gathering performance, long service life, less electric consumption, etc. An emergency battery and a control switch are also arranged, and thus the use of the electric torch with manual power generation function is more convenient.

Description

A kind of hand is pinched the generating torch

Technical field

The utility model relates to a kind of portable illumination device, and especially a kind of hand that generator is housed is pinched the torch of generating.

Background technology

Existing portable lighting lamp all adopts the charge a battery mode of energy storage of civil power to supply the usefulness of Emergency Light on the market.Chargeable at no civil power, when battery did not have electricity again, this illuminating lamp just can't use.The patent No. is CN93215085, denomination of invention is pinched torch for the Chinese patent of " hand-pinch type does not have the battery torch " discloses a kind of hand, its chopped-off head driving rack adopts arc inner tooth tooth bar handle, in handle fixing hole two sides the handle return spring is housed, be fitted together in the axis hole that is fixed to two end plates by handle steady pin substring, during hand pinching handle, the arc inner tooth tooth bar is done circular motion like this, realizes the transmission of internal gear and external gear.So transmission is level and smooth, noise is little, and the comfortable indefatigability of feel has body-building function, alternative dry cell torch.The patent No. is CN02239204, denomination of invention is pinched torch for the Chinese patent of " high brightness does not have the battery torch " discloses another kind of hand, it is to have clamped handle tooth bar, gear shaft assembly, band ratchet pinion, generator, electric bead block, small electric bulb in two shells of rectangle, generator wherein, there is two therebetween unshakable in one's determination stator that installs coil and the p-m rotor that is linked to be by permanent magnet, flywheel and axle axle to be connected, forms 12 utmost point magneto alternators by the permanent magnetism side.When hand pinching handle tooth bar small electric bulb will send high light.Above technology exists common weak point to be: adopt the common bulb structure, brightness is low, and consumed power is big, and the life-span is short.

Summary of the invention

The purpose of this utility model be to overcome the deficiencies in the prior art and a kind of brightness height is provided, the optically focused performance is good, the life-span is long, power consumption is few, hand easy to use is pinched the generating torch.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of hand is pinched the generating torch, comprise housing, reflector and bulb at described housing front end, the handle that band arc inner tooth tooth bar is arranged in the described housing, the handle back-moving spring is arranged on described handle, be engaged with duplicate gear with arc inner tooth tooth bar on the described handle, also has band ratchet pinion with described duplicate gear gear wheel engagement, the ratchet of the p-m rotor endoporus of generator is connected with the ratchet of pinion, it is characterized in that: the circuit board of the bridge rectifier that is constituted by a diode in addition, described bulb is a light emitting diode, is serially connected with resistance between the diode of bridge rectifier and light emitting diode.

For optimizing technique scheme, the measure of being taked also comprises:

Described light emitting diode has 3, is equilateral triangle and distributes in described reflector.

Also have switch and battery, between battery and switch, be serially connected with resistance.

Because the utility model has been taked above-mentioned technical measures, compared with prior art have advantages such as brightness height, the optically focused performance is good, the life-span is long, power consumption is few, also design has emergency cell and switch, also can not light light emitting diode when not handling knob handle, uses convenient.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

See figures.1.and.2, the utility model comprises housing 14, at the front end of housing 14 reflector 1 is arranged, and has 3 to be light emitting diode L1～L3 that equilateral triangle distributes in reflector 1.The handle 3 of band arc inner tooth tooth bar 4 is arranged in the housing 14, handle back-moving spring 10 is arranged on handle 3, be used for the ejection and the closure of joystick 3.Be engaged with duplicate gear 15 with arc inner tooth tooth bar 4 on the handle 3, also have pinion 7 with the band ratchet 8 of gear wheel 6 engagements of duplicate gear 15.The flywheel that band handle ratchet wheel 16 is arranged on the generator M1 p-m rotor 9, pinion 7 removable mountings of band ratchet 8 mesh with flywheel handle ratchet wheel 16 on the axle of p-m rotor 9 flywheel sides, pinion 7 strings are contained on the axle of rotor 9, the engagement of the gear wheel 6 of it and duplicate gear 15 is the secondary transmission, and the pinion 5 of duplicate gear 15 is the chopped-off head transmission with the engagement of the arc inner tooth tooth bar 4 of handle 14.Circuit board 13 comprises the bridge rectifier of being made up of diode D1～D4, be serially connected with resistance R 1 between the diode D1～D4 of bridge rectifier and light emitting diode L1～L3, the electricity that generator M1 is sent is supplied with light emitting diode L1～L3 work by circuit board 13.

During use, pinching handle 3 drives generator M1 p-m rotor 9 and rotates, and the lead in the magnetic force line cutting electricity generator stator coil induces electromotive force and lights bulb.Also design has the button cell B2 and the gauge tap S1 of emergency, is serially connected with resistance R 2 between battery B2 and switch S 1.When not handling knob handle 3,, also can light light emitting diode L1～L3 if switch S 1 is connected battery B2 loop.
