The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, for the preferred embodiment of the utility model light fixture resetting structure, light fixture resetting structure comprises light fixture supporting seat 1, U-shaped fixed mount 2, transmission mechanism 3, be fixed on the locating stop piece 4 on described transmission mechanism 3, optoelectronic switch 5, the support 6 of fixed light electric switch 5, stepper motor 7 and controller (in figure, not indicating), lamp installation is in described U-shaped fixed mount 2, described U-shaped fixed mount 2 is arranged on described light fixture supporting seat 1, described transmission mechanism 3 and described support 6 are fixed on U-shaped fixed mount 2 one sides, described stepper motor 7 is fixed on the bottom surface of described U-shaped fixed mount 2, described stepper motor 7 is in transmission connection with described light fixture 8 by described transmission mechanism 3, described controller is connected with the output of described optoelectronic switch 5.
Preferably, described transmission mechanism 3 comprises gear wheel 31, pinion 32 and odontoid belt 33, odontoid belt 33 is sleeved on gear wheel 31 and pinion 32, described gear wheel 31 is connected with light fixture 8 by power transmission shaft, and described pinion 32 is connected with described stepper motor 7 by the output shaft of stepper motor 7.Drive pinion 32 to rotate by the output shaft of stepper motor 7, pinion 32 passes to gear wheel 31 by odontoid belt 33 by power again, and gear wheel 31 drives light fixture 8 to rotate by power transmission shaft again, therefore can realize the rotation of light fixture 8 by transmission mechanism 3.Further, gear wheel 31 is positioned at the top of described U-shaped fixed mount 2 one sides, described pinion 32 is positioned at the bottom of described U-shaped fixed mount one side, and under described gear wheel 31, be convenient to so reasonably utilize the space of U-shaped fixed mount 2, also just improve the transmission efficiency of transmission mechanism 3, produce better transmission effect.Transmission mechanism 3 of the present utility model can be also other type of belt drive, and as gear drive, gear drive needs two Gear Contacts transmission, and the distance of gear wheel 31 and pinion 32 is nearer like this, can make light fixture have less size; Also can be chain transmission or other type of belt drive, if can pass through stepper motor 7 by power transmission to light fixture 8, and light fixture 8 can be rotated.
Further, be fixed on locating stop piece 4 on gear wheel 31 rounded, the centre of locating stop piece 4 has locating hole, be fixed on gear wheel 31 by key screw locating stop piece 4, the center of circle of locating stop piece 4 is positioned on the central axis of gear wheel 31, the edge of locating stop piece 4 and gear wheel 31 leave certain interval, and for the use of accommodating optoelectronic switch 5, and the edge of locating stop piece 4 is provided with breach 41.The support 6 of fixed light electric switch 5 is fixed on U-shaped fixed mount 2 one sides, and support 6 is located at the below of gear wheel 31, on support 6, be fixed with optoelectronic switch 5, the optoelectronic switch 5 using in the utility model is preferably grooved optoelectronic switch, grooved optoelectronic switch is the one of correlation optoelectronic switch in fact, be called again U-shaped optoelectronic switch, it is a infrared induction photovoltaic, combined by infrared emission tube and infrared receiver tube, groove width has just determined that induction receives the power and the distance that receives signal of model, take light as media, received and conversion by the infrared light between illuminator and photoreceptor, detect the position of object, and be touchless, so can damage check object, also the not impact of examined object, grooved optoelectronic switch is the restriction of examined object hardly, because grooved optoelectronic switch is to adopt the surface of detected object to reflect and light transmission mode, therefore not just for metal, can also be to glass, plastics, wooden objects, the various materials such as liquid carry out detection and Identification.The notch 51 that is positioned at the optoelectronic switch 5 on support 6 just can be across the edge of locating stop piece 4, be that the edge of locating stop piece 4 is by the notch 51 of optoelectronic switch 5, the output of optoelectronic switch 5 is connected with controller, the rotation direction that controller can control step motor 7.
When the light fixture resetting structure of the utility model embodiment is worked, stepper motor 7 rotates, drive light fixture 8 to rotate by transmission mechanism 3, particularly, stepper motor 7 rotates, first drive pinion 32 to rotate by the output shaft of stepper motor 7, pinion 32 passes to gear wheel 31 by odontoid belt 33 by power again, gear wheel 31 drives light fixture 8 to rotate by power transmission shaft again, when gear wheel 31 rotates, be fixed on locating stop piece 4 on gear wheel 31 also along with gear wheel 31 rotates, the edge of locating stop piece 4 is also slowly by the notch 51 of optoelectronic switch 5, the now state of optoelectronic switch 5 in not conducting, when locating stop piece 4 is along with gear wheel 31 is rotated further, when the notch 51 of the breach 41 that is fixed on locating stop piece 4 edges on gear wheel 31 by optoelectronic switch 5, now optoelectronic switch 5 does not detect locating stop piece 4, optoelectronic switch 5 is in conducting state, now signal is passed to controller by optoelectronic switch 5, controller control step motor 7 reverses, drive pinion 32 to rotate backward by the output shaft of stepper motor 7 thus, pinion 32 passes to gear wheel 31 by odontoid belt 33 by power again, and gear wheel 31 drives light fixture 8 to rotate backward by power transmission shaft again, be fixed on locating stop piece 4 on gear wheel 31 also along with gear wheel 31 starts to rotate backward, the edge of locating stop piece 4 is by the notch 51 of optoelectronic switch 5, the now state of optoelectronic switch 5 in not conducting, stepper motor 7 is rotated further, until when the notch 51 of the breach 41 at locating stop piece 4 edges by optoelectronic switch 5, optoelectronic switch 5 is the state in conducting again, by controller, control step motor 7 is reverse again, so constantly circulation, and when the effect the obtaining angle that to be exactly the every rotation of light fixture 8 certain, can reset accurately, rotate backward again and get back to original position, so constantly circulation back and forth, light fixture 8 ceaselessly oscillates, the good lighting effects that produce.And, the size of the emargintion 41 of locating stop piece 4 can directly affect the time of stepper motor 7 in clockwise or counterclockwise rotation, directly have influence on the angle of waving of light fixture 8, it is the scope of the light-illuminating that sends of light fixture 8, therefore the large I of adjusting the emargintion 41 of locating stop piece 4 is determined the size of the range of exposures of light, in the time of the larger light-illuminating area of needs, the emargintion of locating stop piece 4 41 is turned down; In the time of the less light-illuminating area of needs, the emargintion of locating stop piece 4 41 is tuned up.
Adopt light fixture resetting structure of the present utility model, rotate flexibly, accurate positioning, and low cost, can complete continuously swinging back and forth of light fixture; Can automatically reset, not need to operate manually, light fixture resetting structure rational in infrastructure, practical, the scope that light fixture irradiates can regulate, and can meet the user demand of different occasions.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
