Abstract
The utility model relates to a shutter trigger which is characterized in that: a creeping tooth interlock gear, a creeping tooth rotary lever, a shutter touch lever and a shutter touch lever spring are in turn assembled to a machine body through a same shaft, and a planet gear and the creeping tooth rotary lever melt and match with each other; a cam wheel and a gear are in turn connected with the machine body through the other shaft; the other ends of the two shafts are connected with a roof plate through screws. The structure brings about a compacter arrangement of parts and reduces the machine body to a minimum size.
Description
Technical field
The utility model relates to a kind of shutter flip flop equipment, the shutter flip flop equipment that particularly a kind of motor camera is used.
Technical background
The design of general camera is that driving cam and film climbing tooth are positioned over same axle center, benefit be film tube directly driving cam wind up as shutter, but when harm is the film backrush, also drives cam relatively and make shutter open, unless increase other composite structure to compensate.Therefore, the volume of camera increases relatively.
Summary of the invention
The purpose of this utility model provides a kind of shutter flip flop equipment, can make part compacter, thereby camera body is dwindled.
The technical solution of the utility model is: a kind of shutter flip flop equipment, it is characterized in that climbing tooth linked gear, climbing tooth bull stick, shutter touching lever and shutter touching lever spring are assembled on the fuselage successively by same axle, and pinion gear and climbing tooth bull stick hot melt match; Cam wheel links to each other with fuselage by another axle successively with gear; The other end of diaxon links to each other with top board by screw.
The process of winding up: after installing film, bit strip moving climbing tooth in hole moves in the direction of the clock on the film, climbing tooth is contacted directly and is driven pinion gear, cam wheel and cam and rotates (cam wheel and cam are linked to be an one-piece parts) with cam wheel, the cam revolution is moving can be pushed away touching lever toward winding up position (the right) by off-position (left side) once circle, on the position of winding up (the right), preparation is taken pictures by release lever locking touching lever.
Dispose procedure: because the touching lever spring provides permanent thrust to make touching lever toward off-position (left side), when pressing shutter, release lever lifts and discharges touching lever immediately, and this moment, touching lever can be by the position of winding up (the right) rapid migration off-position (left side).Simultaneously the percussion shutter disk made shutter open reaching and clapped the phase purpose this moment.
Because driving cam is not coaxial with the film cam, pinion gear and cam-engaged during volume before the film like this, so cam just can rotate, and the promotion touching lever winds up.During the film backrush, pinion gear and cam disengages so cam just can transfixion, can not make touching lever cause accident to open shutter, and can lower the load of film backrush.
Beneficial effect
The utility model is put in the work of same axle center with climbing tooth linked gear, climbing tooth bull stick, shutter touching lever and shutter touching lever spring, can make part compacter, and the fuselage space is reduced to minimum zone.
Be described further this enforcement is novel below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the vertical view of the utility model shutter flip flop equipment.
When Fig. 2 was preceding volume film, the climbing tooth bull stick was swung left, and pinion gear and cam wheel engagement also drive the synoptic diagram of cam rotation.
When Fig. 3 was the backrush film, the climbing tooth bull stick was swung to the right, the synoptic diagram figure when pinion gear and cam wheel break away from.
Implement concrete mode
As can be seen from Figure 1, climbing tooth linked gear 301, climbing tooth bull stick 302, shutter touching lever 303 and shutter touching lever spring 304 all are assembled on the fuselage 101 by same axle center, and pinion gear 307 matches with climbing tooth bull stick 302 hot melts; Cam wheel 309 links to each other with fuselage 101 by another axle center successively with gear 308; Use 3 screws 306 that it is fixed all above-mentioned parts from top to bottom on top board 305 at last, reach designing requirement.
