[specific embodiment]
Below in conjunction with accompanying drawing and embodiment flashlight is done further description.
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, moves transmission plate 90.Be fixed with reflector 22 on the shell of lamp base 20.
In conjunction with Fig. 3, Fig. 4 and Fig. 5, the main casing 10 inner cavitys that are provided with an opening 12 that form, 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 through screw 42, in other embodiment, can select other modes, and cam disc 30 is driven to rotate when needing only 40 rotations of assurance turning collar.
Turning collar 40 outsides are provided with helicitic texture 42.
Be provided with through hole 62 in the middle of the 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 through 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, and makes light source assembly 50 have the trend that moves to cam disc 30 directions.
Thereby transmission bar 70 passes transmission rod through-hole 64 and is limited on the limiting plate 60, transmits bar 70 and is provided with the sealing ring 72 that improves sealing with limiting plate 60 contact positions.
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 the limiting plate 60.
It is circular moving transmission plate 90, is fixed on the end that heat radiation main body 52 is fixed with light source 54, transmits bar 70 other ends and mobile transmission plate 90 butts.
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 heat radiation main body 252 and extraneous contact area like this, thereby obtained better radiating effect.The particular location of main body through hole 253 is unrestricted, also can be as the criterion with the mechanical strength that does not influence heat radiation main body 252 for passing the main body through hole 253 of heat radiation main body 252 both ends of the surface.
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 helps heat radiation.
When flashlight need be regulated optically focused, floodlight; Rotated circle 40 backs drive cam disc 30 and rotate; Promote to transmit bar 70 and slide,, thereby make that transmitting bar 70 drives moves transmission plate 90 along the flashlight axially-movable owing to cam disc 30 changes with transmitting bar 70 contact position thickness along curved-surface structure 32; Light source assembly 50 moves with mobile transmission plate 90 simultaneously, thereby accomplishes the adjusting of flashlight optically focused, floodlight.
This flashlight relies on the rotation of cam disc 30 to drive and transmits moving along the flashlight axis direction of bar 70; Thereby make that moving transmission plate 90 drives 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 static relatively on the shell of lamp base 20, thereby makes and form relative displacement between light source assembly 50 and the reflector lamp 22, reaches the effect of regulating flashlight optically focused, floodlight adjusting; This flashlight moves the flashlight that reflector is regulated luminous intensity distribution with respect to traditional passing through, and sealing is better.
This flashlight transmission bar 70 is down auxiliary sealing ring 72, 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 claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, 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 accompanying claims.
