Description
Technical field
The utility model relates to a kind of illumination flashlight, relates in particular to a kind of flashlight of tunable optical.
Background technology
In daily life, flashlight becomes people's necessary tool.There are shortcomings such as optically focused is not concentrated, service life is short, manufacturing cost is high, power consumption is big in existing light adjusting type flashlight.Therefore, how to invent that a kind of cost is low, profile is succinct, the tunable optical flashlight of energy-conserving and environment-protective, becomes the task that flashlight research and development production mechanism faces jointly.
The utility model content
The utility model is at the deficiencies in the prior art, and a kind of low cost of manufacture, profile are succinct, the gear lens light modulation flashlight of energy-conserving and environment-protective and provide.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Gear lens light modulation flashlight comprises the circle, the headstock, lamp body and the lamp tail that connect successively, and described lamp body inside is provided with tooth bar, the medial surface of tooth bar is provided with gear, gear is located on the gear shaft, and gear is connected with tooth bar is meshing, and the lateral surface of tooth bar is provided with the tooth bar external member; Described headstock inside is provided with lens, LED light emitting diode, reflecting piece and radiating seat, and radiating seat is fixed on the tooth bar by screw; Lamp body inside is provided with electronic circuit board and battery carrier, and electronic circuit board is electrically connected with the LED light emitting diode; Described lamp tail inside is provided with trim ring, spring and fur cap, and spring is located between trim ring and the fur cap, and the fur cap outside is provided with the afterbody button, and the bottom of battery carrier is connected with the afterbody button.
The junction of described lamp tail and lamp body is provided with O type circle.
Operation principle of the present utility model is: by control the mechanical switch on the battery carrier by the afterbody button, battery carrier is equipped with the 3AAA battery, battery carrier has positive pole and negative pole, directly and the conducting of electronic circuit board both positive and negative polarity, electronic circuit board is drawn the positive and negative polarities line and is connected to LED light emitting diode both positive and negative polarity, has just formed a loop; The stretching light modulation is the rotation by gear, drives tooth bar external member internal tooth bar moving linearly, and radiating seat is fixed on the tooth bar with screw, forms one, Gu and just formed the disjunctor motion, when arriving certain distance, lens just play position-limiting action; When tooth bar is drawn back, arrive the spacing effect that certain distance hour rack external member has just played radiating seat, be the one stroke that stretches like this.
The beneficial effect of the technical program is: by adjust the relative position of light source and lens with gear, tooth bar, realize the effect of optically focused, have the characteristics of easy to operate, good hand touch, stable performance and long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Embodiment, as shown in Figure 1, gear lens light modulation flashlight, comprise the head circle 4, the headstock 3, lamp body 2 and the lamp tail 1 that connect successively, described lamp body 2 inside are provided with tooth bar 13, and the medial surface of tooth bar 13 is provided with gear 14, and gear 14 is located on the gear shaft 15, and gear 14 and 13 meshing connections of tooth bar, the lateral surface of tooth bar 13 is provided with tooth bar external member 12; The described headstock 3 inside are provided with lens 20, LED light emitting diode 18, reflecting piece 19 and radiating seat 17, and radiating seat 17 is fixed on the tooth bar 13 by screw 16; Lamp body 2 inside are provided with electronic circuit board 11 and battery carrier 10, and electronic circuit board 11 is electrically connected with LED light emitting diode 18; Described lamp tail 1 inside is provided with trim ring 8, spring 7 and fur cap 6, and spring 7 is located between trim ring 8 and the fur cap 6, and fur cap 6 outsides are provided with afterbody button 5, and the bottom of battery carrier 10 is connected with afterbody button 5.
The junction of described lamp tail 1 and lamp body 2 is provided with O type circle 9.
Can guarantee the axiality of lens and LED during the utility model used in the long-term time, this is to surmount greatly in one of this field of stretching; Work in-process only need time processing just can, need not to reprocess after the deoxidation, only need an once mounting operation just can put in place, other simple processing both can, reduced the process-cycle, reduced cost, profile is succinct and don't lose generous; In function aspects, we pay attention to energy-conservation, and with this one side of personal safety field, design the third gear function: the user can select best gear according to outdoor different lighting condition, can reduce some unnecessary power consumptions, to have improved the service time of battery.Very simple of configuration aspects, dimming function is apparent, avoids the hidden loaded down with trivial details flashlight of those functions on the market.Because structure and installation is simple and easy, oneself just can keep in repair, and has saved unnecessary trouble, has prolonged service life, uses object to expand to old man, child by a middle-aged person, and those can not see the user who understands Chinese, and its market potential is huge.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
