Abstract
A negative driving and switching mechanism of a projective lamp comprises a speed reduction motor (1), a drive gear (2), a plurality of negative tray gears (3, 4, 5, 6) and a pattern tray (7); wherein, the rotational shaft of the speed reduction motor (1) arranged on a base seat is firmly connected with the drive gear (2), a ratchet wheel (8) is arranged on the pattern tray (7), a cam (9) is arranged on the rotational shaft of the speed reduction motor (1), the ratchet wheel (8) is firmly connected with the pattern tray (7), the outer tooth ring of the ratchet wheel (8) is interlocked with a pawl (10), and the cam (9) is firmly connected with the rotational shaft of the speed reduction motor (1). During operation, the speed reduction motor drives the drive gear to drive the negative tray gears to rotate, when the speed reduction motor rotates for one circle, the cam also rotates for one circle and pushes the pawl in order to unlock the ratchet wheel. Widely applicable to stages and the field of advertisement, the utility model has the advantages of simple structure, reliable operation, compact volume and low cost in production and maintenance.
Description
Technical field
The utility model relates to stage and advertising equipment, especially a kind of driving of projection lamp egative film and switching mechanism.
Background technology
Projection lamp is widely used in stage and the ad distribution equipment, and its mechanism is made of light source, light collection system, egative film driving and switched system, imaging system.Its egative film of existing product drives and switched system is made of single-chip microcomputer, stepper motor mostly, and a stepper motor is responsible for driving egative film and is rotated, and another stepper motor is responsible for egative film and is switched.When being used for advertising equipment, because its working time is long, the thermal value height, reasons such as poor working environment make single-chip microcomputer damage easily, and the easy step-out of stepper motor, the equipment failure rate height, maintenance cost is big, and service efficiency is low.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and working stability is reliable, and volume is little, and a kind of projection lamp egative film of low cost of manufacture switches simple mechanism.
The driving of described projection lamp egative film and switching mechanism comprise reducing motor 1, driven wheel 2, a plurality of egative film tray gear 3,4,5,6 etc., the rotating shaft that is arranged on the reducing motor 1 on the base is fixedlyed connected with driven wheel 2, it is characterized in that: described mechanism also is provided with pattern disk 7, pattern disk 7 is provided with ratchet 8, also is provided with cam 9 in the rotating shaft of reducing motor 1; Described ratchet 8 is fixedlyed connected with pattern disk 7, ratchet 8 external tooths circle and ratchet 10 interlockings, and described cam 9 is fixedlyed connected with reducing motor 1 rotating shaft.The other end of ratchet 10 is connected with base 12 by spring 11.Described cam 9 is rotating a Zhou Shiding from ratchet 8 once.Described pattern disk 7 central through holes are rotationally connected by the rotating shaft of bearing and reducing motor 1, the last plane of pattern disk 7 is rotationally connected by bearing with a plurality of egative film tray gears 3,4,5,6 lower ends respectively, and the gear teeth of a plurality of egative film tray gears 3,4,5,6 mesh with driven wheel 2 respectively.
The utility model is when work, and the reducing motor rotational driving gear drives egative film tray gear autobiography, and this moment, pattern disk did not rotate, and when reducing motor rotated a circle, cam also rotated a circle, and cam also pushes ratchet, removes the interlocking to ratchet.Because ratchet and pattern disk are fixed as one, egative film tray gear and pattern disk, drive gear set becomes epicyclic gearing, and under its driving force, produced a geneva motion, thereby finish the switching of an egative film, go round and begin again, finish the switching and the rotation of all egative film tray gears on the pattern disk.
The utility model is simple in structure, reliable operation, and volume compact, manufacturing and maintenance cost are low, are widely used in stage and advertisement field.

Among the figure: 1-reducing motor, 2-driven wheel, 3,4,5,6-egative film tray gear, 7-pattern disk, 8-ratchet, 9-cam, 10-ratchet, 11-spring, 12-base.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: among Fig. 1,2, the driving of described projection lamp egative film and switching mechanism, comprise reducing motor 1, driven wheel 2, a plurality of egative film tray gear 3,4,5,6, pattern disk 7, the rotating shaft that is arranged on the reducing motor 1 on the base is fixedlyed connected with driven wheel 2, it is characterized in that:, pattern disk 7 is provided with ratchet 8, also is provided with cam 9 in the rotating shaft of reducing motor 1; Described ratchet 8 is fixedlyed connected with pattern disk 7, ratchet 8 external tooths circle and ratchet 10 interlockings, and described cam 9 is fixedlyed connected with reducing motor 1 rotating shaft.The other end of ratchet 10 is connected with base 12 by spring 11.Described cam 9 is rotating a Zhou Shiding from ratchet 8 once.Described pattern disk 7 central through holes are rotationally connected by the rotating shaft of bearing and reducing motor 1, the last plane of pattern disk 7 is rotationally connected by bearing with a plurality of egative film tray gears 3,4,5,6 lower ends respectively, and the gear teeth of a plurality of egative film tray gears 3,4,5,6 mesh with driven wheel 2 respectively.
Its course of work is: the reducing motor rotational driving gear, drive egative film tray gear autobiography, and this moment, pattern disk did not rotate, and when reducing motor rotated a circle, cam also rotated a circle, and cam also pushes ratchet, removes the interlocking to ratchet.Because ratchet and pattern disk are fixed as one, egative film tray gear and pattern disk, drive gear set becomes epicyclic gearing, and under its driving force, produced a geneva motion, thereby finish the switching of an egative film, go round and begin again, finish the switching and the rotation of all egative film tray gears on the pattern disk.
