Description
Technical field
The utility model belongs to tutor auxiliary platform equipment technical field, is specifically related to a kind of boost line generating apparatus for English Class writing on the blackboard.
Background technology
On current English Class; period can carry out a certain amount of writing on the blackboard to English Instructor usually at school; the English Instructor few for some experience with students and concept of space is bad; often have writing on the blackboard to the not carefully and neatly done phenomenon such as different directions inclination; not only unsightly, while, sense organ is unfavorable for the understanding of student.
Utility model content
The purpose of this utility model is to propose a kind of boost line generating apparatus for English Class writing on the blackboard, the phenomenon that the English Instructor's writing on the blackboard existed in solution prior art is not carefully and neatly done.
For achieving the above object, the boost line generating apparatus for English Class writing on the blackboard of the present utility model comprises motor, lifter plate, base plate, thread spindle, yi word pattern laser instrument, bumping post, control module and driver;
Described motor is fixed on described base plate by motor rack, described motor output shaft is connected with described thread spindle one end by shaft coupling, described thread spindle and described lifter plate threaded one end are connected, the other end of described lifter plate is fixed with yi word pattern laser instrument by briquetting, and two sides of described lifter plate are provided with bumping post;
Described control module control and drive system drive motor rotates, and then drives lifter plate to move up and down.
The angle theta span of described lifter plate and surface level is: 0 < θ < 90 °.
Described bumping post is connected with base thread.
The beneficial effects of the utility model are: the boost line generating apparatus for English Class writing on the blackboard of the present utility model can make yi word pattern laser instrument luminous by switching on power, by laser projection on blackboard, yi word pattern laser instrument is pressed on lifter plate by briquetting, lifter plate completes lifting by screw thread and threaded shaft fits, thus realize the change of laser height on blackboard, efficiently solve writing on the blackboard and write not carefully and neatly done phenomenon.
Accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram of the boost line generating apparatus for English Class writing on the blackboard of the present utility model;
Wherein: 1, motor, 2, motor rack, 3, shaft coupling, 4, thread spindle, 5, lifter plate, 6, base plate, 7, yi word pattern laser instrument, 8, briquetting, 9, bumping post.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
See accompanying drawing 1, the boost line generating apparatus for English Class writing on the blackboard of the present utility model comprises motor 1, lifter plate 5, base plate 6, thread spindle 4, yi word pattern laser instrument 7, bumping post 9, control module and driver;
Described motor 1 is connected with motor rack 2 by screw, motor rack 2 is fixed by screws on described base plate 6, described motor 1 output shaft is rigidly connected by shaft coupling 3 and described thread spindle 4 one end, described thread spindle 4 is connected with described lifter plate 5 threaded one end, the other end of described lifter plate 5 is fixed with yi word pattern laser instrument 7 by briquetting 8, briquetting 8 and described lifter plate 5 are connected by screw, yi word pattern laser instrument 7 is pressed on described lifter plate 5 by described briquetting 8, and two sides of described lifter plate 5 are provided with bumping post 9;
Described control module control and drive system drive motor 1 rotates, and then drives lifter plate 5 to move up and down.
Described lifter plate 5 with the angle theta span of surface level is: 0 < θ < 90 °.
Described bumping post 9 one end is threaded, and is coordinated, be screwed into the on base plate 6 by the threaded hole corresponding with base plate 6.
Send instruction by control module to motor 1 during work, control motor 1 and rotate, motor 1 drives thread spindle 4 to rotate by shaft coupling 3, and thread spindle 4 controls the lifting of lifter plate 5 by threaded engagement, and motor 1 rotates forward, and rises, and motor 1 reverses, and declines.Bumping post 9 keeps off in lifter plate 5 both sides, prevents lifter plate 5 from rotating.Control module control yi word pattern laser instrument 7 is lighted and is sent laser, makes laser projection on blackboard, thus the boost line realizing English Class writing on the blackboard generates and the adjustment of boost line height.
