Abstract
The utility model discloses a mechanism with electronic focus adjusting and manual focus adjusting capable of being switched over. The mechanism comprises a motor installation frame, a multi-head motor, a flange with an inner thread, a handle, a linkage plate, a connecting rod, a lens combination and an LED plate. The handle is movably arranged on an output rod of the multi-head motor, and is provided with a contact switch capable of making contact with the handle. In the operating process, the electronic focus adjusting and manual focus adjusting can be switched over only by changing the position, relative to the contract switch, of the handle, and therefore the mechanism is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to light fixture, particularly stage lamp.
Background technology
In order to realize different stage-lighting effects, the application of Zoom structure in stage lamp is more and more extensive.The focusing in past has by electromotion focusing, also have by manual focusing, above-mentioned two kinds of methods cut both ways, if used separately, advantageous point cannot be brought into play in a desk lamp tool, therefore, occurred afterwards both thering is electromotion focusing and also had the light fixture of manual focusing, as at application number being discloses a kind of NL1000 spotlight in the 201120329595.7 Granted publication days patent documentation that is 2012.6.20, and specifically disclose NLI000 spotlight and comprise light source, focusing system and cooling system.The implementation of focusing system is that outside knob is connected with tooth bar by gear drive, regulates the distance of Fresnel Lenses to light source by rotating focusing knob, reaches the effect of manual focusing; Gear is connected with motor by gear shaft, and on control panel, focusing knob can be controlled the startup of motor, thereby can pass through electromotion focusing.Although the light fixture of this structure can be realized manual focusing and electronic zooming, its complex structure, and inconvenient operation.
Summary of the invention
For simplified structure, convenient operation, the mechanism that the utility model provides a kind of electronic zooming and manual focusing to switch mutually.
For achieving the above object, the mechanism that a kind of electronic zooming and manual focusing can switch mutually, comprises motor mounting rack, bull motor, tapped flange, handle, linkage board, connecting rod, lens combination and LED board; Bull motor is fixed on motor mounting rack; Tapped flange is located on the take-off lever of bull motor; Linkage board is fixed on tapped flange; The lower end of connecting rod is connected with linkage board, and the upper end of connecting rod is connected with lens combination; LED board is located at the below of lens combination; On the take-off lever that is located at bull motor of described handle activity, be also provided with the contact switch that can contact with handle.
Further, described handle comprises connecting portion and is connected to the knob on connecting portion, and the outstanding connecting portion in knob outside is provided with square opening on connecting portion, and the end that is inserted into the bull motor take-off lever of square opening is square pole.
Further, contact switch be positioned at knob directly over.
The beneficial effects of the utility model are: pull down fixed handle, handle departs from contact switch, bull electrical power, the take-off lever rotation of bull motor, flange rectilinear motion, flange drives linkage board to move up and down, and linkage board is closed and moved up and down by connecting rod drive lens group, reaches the object of electrical adjustment; Upwards driving handle, handle contacts with contact switch, and motor power-off can reach the object of manual adjustments by rotary handle.Therefore, in operating process, as long as lever change can make electronic zooming and manual focusing mutually convert with respect to the position of contact switch, therefore, simple in structure, easy to operate.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the exploded view of the utility model structure.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As depicted in figs. 1 and 2, the mechanism that electronic zooming and manual focusing can switch mutually comprises motor mounting rack 1, bull motor 2, tapped flange 3, handle 4, contact switch 5, linkage board 6, connecting rod 7, lens combination 9 and LED board 8.
Motor mounting rack 1 comprises motor mounting plate 11, connecting plate 12, contact switch fixed head 13, and connecting plate 12 extends downwards from an edge of motor mounting plate 11, and contact switch fixed head 13 extends to the inside from the lower end of connecting plate; On motor mounting plate 11, be provided with through hole 111, pass for the take-off lever of bull motor.
Bull motor 2 is fixed on motor mounting plate 11; Tapped flange 3 is located on the take-off lever that is positioned at bull motor top.
Described handle 4 comprises connecting portion 41 and is connected to the knob 42 on connecting portion, connecting portion 41 is given prominence in knob 42 outsides, on connecting portion 41, be provided with square opening 411, the end that is inserted into the bull motor take-off lever of square opening is square pole, and connecting portion 41 with output shaft for being flexibly connected.
Linkage board 6 is fixed on tapped flange 3; The lower end of connecting rod 7 is connected with linkage board 6, and the upper end of connecting rod 7 is connected with lens combination 9; LED board 8 is located between linkage board 6 and lens combination 9, and is positioned at the below of lens combination.
The operation principle of said structure is: pull down fixed handle 4, handle 4 departs from contact switch 5, bull motor 2 is switched on, the take-off lever rotation of bull motor 2, flange 3 rectilinear motions, flange 3 drives linkage board 6 to move up and down, and linkage board 6 moves up and down by connecting rod 7 drive lens combinations 9, reaches the object of electrical adjustment; Upwards driving handle 4, handle contacts with contact switch 5, and motor 2 power-off can reach the object of manual adjustments by 4 of rotary handles.Therefore, in operating process, as long as lever change can make electronic zooming and manual focusing mutually convert with respect to the position of contact switch, therefore, simple in structure, easy to operate.
