In conjunction with the accompanying drawings the utility model embodiment is described in further detail now.
The utility model is made of fuselage (1), focus adjusting mechanism (2), view finder (3), lens mount (4), camera lens (14), bellows (15), tripper (5), winding mechanism (16), film case (6).Wherein focus adjusting mechanism (2), view finder (3) all are screwed on fuselage (1), and lens mount (4) connects with fuselage (1) through bellows (15).Film case (6) is contained on the fuselage on (1).Tripper (5) is contained in fuselage (1) right side, and its dimmer is made of rectangular-shaped last shadow shield (34) and following shadow shield (36).The left end of the coboundary of last shadow shield and last bent axle (35) is fixed, and its right-hand member penetrates in the lever that opens the door (33) the upper arm slotted hole.The lower limb of following shadow shield (36) is fixed with the left end of following bent axle (37), and its right-hand member penetrates in the slotted hole of the lever that opens the door (33) underarm.The lower limb of last shadow shield (34) is provided with crimp, and it can tight connecting with the coboundary of following shadow shield (36).
Right side, reflector (44) middle part is provided with control nail, the oblique arm of being close to master control lever (32), the by-level arm of master control lever (32) contacts with the main control unit that has breach (31) pin, master control lever (32) lower end is provided with the circular shaft of fluting, and it is fixing with the gong nail with the trigger piece that is exposed at the tripper (5) outside fuselage (1) right side.Lever (33) upper arm that opens the door is provided with clubfoot, and copper flash of light contact (49) is installed in its opposite.Lock is put and is colluded (38) and be contained in main control unit (31) top, and the pin of master control lever (32) upper arm is aimed on its inclined-plane simultaneously.Trip lever (39) upper end is provided with crotch, is close to the edge of main control unit (31), and its lower end contacts with a pin of shutter driver plate (41).Be provided with circular hole in the middle of the B door lever (40), be sleeved on the circular shaft of trip lever (39).Shutter selects button (42) to be contained in the middle of two arms of B door lever (40).Shutter driver plate (41) upper end is provided with driver plate spring (48), and its lower end is provided with thimble (50).
Winding mechanism of the present utility model (16) is formed shell by train wheel bridge (21), lower plate (27) and base plate (26).Counting scale (23), winding knob (29), cylinder (24), roller bearing (28) and two film top buttons (20) are formed the roll film core.Counting scale (23) is contained on the train wheel bridge (21), and is sleeved on the circular shaft upper end of cylinder (24).Evenly be printed on 0-9 0 numerals above the counting scale (23), be provided with pointer above it, the circular shaft upper end of its axle center and cylinder (24) is screwed.
Focus adjusting mechanism of the present utility model (2) is provided with gear shaft (10) and tooth bar (9), and both all have helical teeth, coincide mutually.Tooth bar (9) is fixed on above the tooth bar seat (8), and tooth bar seat (8) is fixed on above the focusing railroad shoe (7).Fuselage (1) front end tightens up with screw with the rear end of focusing railroad shoe (7).Gear shaft (10) is equipped with at camera lens mounting (12) middle part, and lens mount (4) is equipped with on top, and the gear shaft end face is provided with knob (13).
The utility model principle of work is as follows:
When tripper (5) exposed parts trigger piece is depressed, master control lever (32) moves thereupon, a horizontal arm in the middle of it is stirred main control unit (31) pin, it is rotated by inhour, the pin of master control lever (32) upper arm is put the inclined-plane that colludes (38) near lock gradually when continuing to press, and lock is put colluded (38) and lift gradually.And reflector (44) is because of own wt, and the roundlet axle in the middle of its glides along master control lever (32) inclined-plane, till reflector (44) and camera lens angle at 45.When loosening the trigger piece of tripper (6), lock is put the pin that the breach that colludes (38) catches on master control lever (32) upper arm, forces it not raise up, and can focus and find a view this moment.
After focusing is correct, press the trigger piece of tripper (5) once more, master control lever (32) upper arm pin is put from lock and is colluded (38) breach slippage, and master control lever (32) raises up, and its oblique arm promotes reflector (44) and rises, and covers view finder (3), performs to take and prepares.
The pressing shutter release button, a pin of shutter driver plate (41) promotes trip lever (39), the crotch of its upper end is thrown off the edge of main control unit (31), main control unit rotates under the main spring effect toward the clockwise direction, forces the lever that opens the door (33) and then to rotate, last bent axle (35) and following bent axle (37) lever (33) that opened the door is respectively stirred, certainly also drive last shadow shield (34) and raise up, and shadow shield (37) falls down, shutter opening.Under action of reset spring, two shadow shields are closed rapidly again up and down, finish single exposure.
When shutter selected button (42) to be placed on B door position, an arm of B door lever (40) caught on main control unit (31) and can not rotate, and made not reset after two shadow shields are opened up and down, did time exposure.And then manually loosen shutter driver plate (41), and force B door lever (40) to loosen main control unit (31), in its spring action turning down, shutter close is finished time exposure.When shutter was opened to maximum, a clubfoot of the lever that opens the door (33) is connected flash of light contact (49) triggered flashlamp.
The effect of thimble (50) is: when the plate in the film case (6) did not draw back, shutter driver plate (41) was blocked, and does not press shutter, can prevent the leak-stopping bat.
After loading onto film, the film lining paper slips over from cylinder (24) and roller bearing (28), and the lining paper friction drives cylinder (24), and the pointer of winding mechanism (16) rotates thereupon.396 ° of its revolutions, the about 83mm of film trasport, the picture physical length is 76mm, the about 6-7mm of separator bar is so every volume 120 films can be clapped 10.Pointer of every bat rotates 11/10 circle, the result pointer numeral that marches ahead.Tooth bar (9) and gear shaft (10) have helical teeth, coincide mutually again, and when manual adjusting knob (13), stable drive, displacement gap, front and back is little, thereby focus adjusting mechanism work precision, and the camera lens focusing is accurately.
