[specific embodiment]
Below in conjunction with drawings and Examples, flashlight is further described.
Flashlight as depicted in figs. 1 and 2 comprises main casing 10, shell of lamp base 20, cam disc 30, turning collar 40, light source assembly 50, limiting plate 60, transmits bar 70, spring 80, mobile transmission plate 90.Be fixed with reflector 22 on shell of lamp base 20.
In conjunction with Fig. 3, Fig. 4 and Fig. 5, the inner cavity that is provided with an opening 12 that forms of main casing 10, the arranged outside at opening 12 places of main casing 10 has external screw thread 14.
Shell of lamp base 20 is the bowl cover shape, and inwall is provided with internal thread 24.
In the present embodiment, turning collar 40 is fixed on cam disc 30 outsides by screw 42, in other embodiment, can select other modes, as long as when guaranteeing that turning collar 40 rotates, cam disc 30 is driven to rotate.
Turning collar 40 outsides are provided with helicitic texture 42.
Be provided with through hole 62 in the middle of limiting plate 60, the edge is provided with and transmits rod through-hole 64 and fixing hole 66, and limiting plate 60 is fixed on opening 12 places of main casing 10 by fixing hole 66 and screw.
The end that heat radiation main body 52 is fixed with light source 54 passes through hole 62, spring 80 two ends respectively with limiting plate 60 and external structure 56 butts, spring 80 is compressed, makes light source assembly 50 have the trend that moves to cam disc 30 directions.
Pass and transmit rod through-hole 64 and be limited on limiting plate 60 thereby transmit bar 70, transmit bar 70 and be provided with limiting plate 60 contact positions the sealing ring 72 that improves sealing.
Transmit bar 70 1 ends and curved-surface structure 32 butts, limiting plate 60 is fixed on opening 12 places of main casing 10, transmits bar 70 and is limited on limiting plate 60.
As shown in Figure 6, in another embodiment, in order to obtain better radiating effect, the sidewall of columned heat radiation main body 252 is provided with main body through hole 253.Increase like this contact area in heat radiation main body 252 and the external world, thereby obtained better radiating effect.The particular location of main body through hole 253 is unrestricted, also can for passing the main body through hole 253 of heat radiation main body 252 both ends of the surface, be as the criterion with the mechanical strength that does not affect heat radiation main body 252.
As shown in Figure 7, in another embodiment, circular mobile transmission plate 290 is provided with transmission plate through hole 292 is set, thereby more is conducive to heat radiation.
When flashlight need to be regulated optically focused, floodlight, rotating the rear drive cam disc 30 of turning collar 40 rotates, promoting to transmit bar 70 slides along curved-surface structure 32, because cam disc 30 and transmission bar 70 contact position thickness change, transmit the bar 70 mobile transmission plate 90 of drive along the flashlight axially-movable thereby make, light source assembly 50 moves simultaneously with mobile transmission plate 90, thereby completes the adjusting of flashlight optically focused, floodlight.
This flashlight relies on rotarily driving of cam disc 30 to transmit moving along the flashlight axis direction of bar 70, thereby make mobile transmission plate 90 drive light source assembly 50 motions, make light source assembly 50 move along the flashlight axis direction, and simultaneously reflector 22 is fixed on and keeps relatively static on shell of lamp base 20, thereby make between light source assembly 50 and reflector lamp 22 and form relative displacement, reach the effect of regulating flashlight optically focused, floodlight adjusting; This flashlight is with respect to traditional flashlight that mobile reflector is regulated luminous intensity distribution that passes through, and sealing is better.
This flashlight transmits bar 70 under sealing ring 72 auxiliary, and sealing further improves, the protection that goes for diving under water.
The above embodiment has only expressed one or more embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
