Description
Technical field
The utility model relates to a kind of optical device, relates in particular to a kind of shutter device.
Background technology
In the light path folding control gear in many optical devices, application be the rotary folding of motor-driven optical gate.Motor-driven optical gate relates to more part combination, and relative cost is higher.
The utility model content
The utility model technical matters to be solved provides a kind of advantages of simple more, shutter device that cost is low.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be
A kind of shutter device; Comprise an optical gate and fixed mount; Described shutter device is provided with the electromagnet that drives optical gate, and described optical gate is long strip-board shape, L-shaped tabular, the optical gate guide plate and the electromagnet fixed head that comprise front end of described fixed mount; Coupling offers the light-trapped opening that lets described optical gate guiding ground not pass rotationally on the optical gate guide plate; Electromagnet ontology is fixedly installed on the electromagnet fixed head, and the spool and the optical gate of said electromagnet is in transmission connection, drives optical gate in to-and-fro movement, and the rear end of said electromagnet spool is provided with back-moving spring.
On described optical gate guide plate, preferably be set with an optoelectronic switch; Matched position in described long strip-board shape optical gate side also is provided with the protrusion flank; When said optical gate is in when stretching out off-position; The protrusion flank just in time moves between the emitter and receiving pole of said optoelectronic switch, the said emitter of blocking-up is to the light path of receiving pole, and when said optical gate was in the withdrawal open site, the detection flank just in time shifted out the emitter of said optoelectronic switch and the light path between the receiving pole.
Described long strip-board shape optical gate preferably is cruciform, and said optical gate is provided with the protrusion flank in the both sides of said optical gate guide plate back, and when said optical gate was in extended position, described protrusion flank front edge was limited in said optical gate guide plate.
The employed electromagnet outsourcing of the utility model cost is very cheap, and part is few, and is simple in structure, and processing cost is low, dependable performance.Electromagnet ontology is fixed on the electromagnet fixed head, guarantees that the body-fixed of electromagnet is motionless.The spool of electromagnet drives the optical gate motion.The guiding square hole is arranged on the optical gate limiting plate, and optical gate passes square hole, and square hole can prevent the valve core rotation of electromagnet.Electromagnet links to each other with controller; By the energising and the no power of the controller of equipment control electromagnet, when the electromagnet energising promotes spool forward, promote optical gate and move forward and close main optical path; When electromagnet cuts off the power supply; The electromagnet spool is return the original position under the effect of back-moving spring, main optical path is opened in the playback of pulling optical gate.
When device is provided with optoelectronic switch; The shutter device of the utility model has just possessed measuring ability simultaneously, and optoelectronic switch has signal emitters and receiving pole, when optical gate is withdrawn by the spool pull-up of solenoid valve; Receiving pole is received the signal indication optical gate of emitter and is opened, and main optical path has light to pass through; When optical gate was released by the electromagnet spool, the protrusion flank of optical gate was blocked between the receiving pole and emitter of optoelectronic switch, and receiving pole does not receive that the signal indication optical gate of emitter is closed, and main optical path does not have light to pass through.The detection signal that the operator can send according to optoelectronic switch intuitively the judgment task system state, take corresponding favourable measure.
Optical gate is cruciform, and the optical gate guide plate can stop the stroke of the criss-cross protrusion flank of optical gate ears or side handles of a utensil restriction optical gate.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
Fig. 1 shows a kind of shutter device; Comprise an optical gate 1 and fixed mount 2; Described shutter device is provided with the electromagnet 3 that drives optical gate 1, and described optical gate 1 is long strip-board shape, L-shaped tabular, the optical gate guide plate 21 and the electromagnet fixed head 22 that comprise front end of described fixed mount 2; Coupling offers the optical gate square hole that lets described optical gate 1 guiding ground not pass rotationally on the optical gate guide plate 21; Electromagnet ontology is fixedly installed on the electromagnet fixed head 22, and the spool 31 and the optical gate 1 of said electromagnetism 3 iron are in transmission connection, drive optical gate 1 in to-and-fro movement, and the rear end of said electromagnet spool 31 is provided with back-moving spring 4.
On described optical gate guide plate 21, be set with an optoelectronic switch 5; Described long strip-board shape optical gate 1 is cruciform; Said optical gate 1 is provided with protrusion flank 11 in the both sides of said optical gate guide plate 21 back; When said optical gate 1 was in extended position, described protrusion flank 11 front edges were limited in said optical gate guide plate 21.When said optical gate 1 is in extended position; The main optical path of optical gate 1 closing device; Protrusion flank 11 just in time moves between the emitter and receiving pole of said optoelectronic switch 5, the said emitter of blocking-up is to the light path of receiving pole; When said optical gate 1 was in the withdrawal open site, the protrusion flank just in time shifted out the emitter of said optoelectronic switch and the light path between the receiving pole.
Certainly from different equipment requirements,, also optoelectronic switch can be set if equipment need not possess measuring ability.And to the mobile spacing conventionally form that also can select other for use of optical gate 1, even be not provided with spacing because the position that also can limit optical gate that is connected of electromagnet spool itself and optical gate is provided with the spacing just for more reliable and more stable of protrusion flank.
