Abstract
A kind of novel prism Zoom structure, comprise frame, stepper motor, jacking gear, lifting table, fixed bar, prism, wherein: frame is divided into upper bracket and lower carriage, described stepper motor one and stepper motor two are arranged on lower carriage respectively, be positioned on the diagonal angle in middle level, stepper motor connects the lifting shaft of jacking gear, lifting shaft there is screw thread, lifting shaft is overlapped by screw thread be connected with lifting, lifting cover is arranged on lifting table, lifting table is arranged on upper bracket, and fixed bar, through lower carriage, upper bracket and lifting table, is provided with prism in the middle of lifting table.The utility model solves unicity and the instability of conventional prism zoom.
Description
Technical field
The utility model relates to lens focusing field, particularly a kind of novel prism Zoom structure.
Background technology
Along with various modern stage demand, the gorgeous light that stage lighting produces, the visual effect of various novelty attracts the eyeball of spectators ,-but current stage lighting technology still shortcoming is numerous, complex operation, slow movement.
Utility model content
In order to solve the shortcoming of prior art, the purpose of this utility model is to provide automatic focusing, implements a kind of novel prism Zoom structure convenient, lasting accuracy is high.
The utility model solves the technical scheme that its technical matters adopts: a kind of novel prism Zoom structure, comprise frame, stepper motor, jacking gear, lifting table, fixed bar, prism, wherein: frame is divided into upper bracket and lower carriage, described stepper motor one and stepper motor two are arranged on lower carriage respectively, be positioned on the diagonal angle in middle level, stepper motor connects the lifting shaft of jacking gear, lifting shaft there is screw thread, lifting shaft is overlapped by screw thread be connected with lifting, lifting cover is arranged on lifting table, when stepper motor starts, drive lifting shaft rotates, lifting shaft is rotated by threaded engagement and lifting cover, thus drive lifting table to realize lifting, lifting table is arranged on upper bracket, fixed bar is through lower carriage, upper bracket and lifting table, fixing lower carriage, upper bracket, the relative position of lifting table, in the middle of lifting table, prism is installed, realize the function of zoom.
As further improvement of the utility model: described lifting shaft and the motors of stepper motor connect, and motor flows to lifting shaft with the moment of torsion of 1:1.
As further improvement of the utility model: described stepper motor is provided with position detecting system, position detecting system comprises dislocation warning horn and self-checking device, self-checking device connects supervisory control desk, is regulated the height of lifting table, realize zoom by supervisory control desk.
Compared with prior art, the beneficial effects of the utility model are:
The utility model changes and realized zoom by pulley drive in the past, stepper motor connects the lifting shaft of jacking gear, lifting shaft there is screw thread, lifting shaft overlap by screw thread is connected with lifting, is elevated cover and is arranged on lifting table, during stepper motor startup, drive lifting shaft rotates, lifting shaft is rotated by threaded engagement and lifting cover, thus drives lifting of lifting table, realizes zoom.
Described lifting shaft motors that is direct and stepper motor connects, and motor flows to lifting shaft with the moment of torsion of 1:1, reduces the consumption of electricity, adds the accuracy of lifting.
Described stepper motor is provided with position detecting system, position detecting system comprises dislocation warning horn and self-checking device, self-checking device connects supervisory control desk, the height of lifting table is regulated by supervisory control desk, realize zoom, prevent the lifting table that causes because of stepper motor Long-Time Service or misoperation out-of-level, the damage parts caused.
Accompanying drawing explanation
Fig. 1 is topology view of the present utility model;
Fig. 2 is jacking gear view of the present utility model.
Embodiment
Existing accompanying drawings and embodiment further illustrate the utility model:
With reference to figure 1 and Fig. 2, a kind of novel prism Zoom structure, comprise frame 1, stepper motor 5, jacking gear 8, lifting table 2, fixed bar 3, prism 4, wherein: frame 1 is divided into upper bracket 101 and lower carriage 102, described stepper motor 501 and stepper motor 502 are arranged on lower carriage 102 respectively, be positioned on the diagonal angle in middle level, stepper motor 5 is provided with position detecting system, position detecting system comprises dislocation warning horn 901 and self-checking device 902, stepper motor 5 connects the lifting shaft 6 of jacking gear 8, described lifting shaft 6 is directly connected with the motor 10 of stepper motor 5, motor 10 flows to lifting shaft 6 with the moment of torsion of 1:1, lifting shaft 6 there is screw thread, lifting shaft 6 is connected with lifting cover 7 by screw thread, lifting cover 7 is arranged on lifting table 2, when stepper motor 5 starts, lifting shaft 6 is driven to rotate, lifting shaft 6 is rotated by threaded engagement and lifting cover 7, thus drive lifting table 2 to realize lifting, lifting table 2 is arranged on upper bracket 101, fixed bar 3 is through lower carriage 102, upper bracket 101 and lifting table 2, fixing lower carriage 101, upper bracket 102, the relative position of lifting table 2, in the middle of lifting table 2, prism 4 is installed, realize the function of zoom.
In sum; after those of ordinary skill in the art reads the utility model file; make other various corresponding conversion scheme according to the technical solution of the utility model and technical conceive without the need to creative brainwork, all belong to the scope that the utility model is protected.
