Abstract
The utility model relates to a projector for uniform-speed circular movement, which comprises a movement display portion, a mechanical driving portion and an image drawing portion. The movement display portion and the mechanical driving portion are respectively arranged on the front side and the back side of a middle separation board. An indicating needle is connected with a guiding board by a connection board. A disk gear drives the guiding board to conduct translatory movement by a deflector rod. Meanwhile, the indicating needle synchronously conducts translatory movement. The indicating needle, the disc, the single pendulum ball and the luminous tube of the movement display portion are arranged on the same flat surface of movement visual sense. A hair pencil is arranged on the connection board which can conduct translatory movement. A paper conveying roller is driven by a belt to drive a recording paper belt to act. The simple harmonic vibration of the hair pen and the uniform-speed advancement of the paper belt are combined to draw sine curves. The projector has intuitional demonstration effect and is an ideal tool for class teaching.
Description
The utility model belongs to the instruments used for education field, particularly relates to a kind of instrument of demonstration uniform circular motion lateral projection.
Existing uniform circular motion projector, as the product of the same name that Qianjiang City, Hubei produces, motion is vertically to be placed on the disc level face, the single pendulum bead is periodically controlled by electromagnet, only reflects the swing of one-period and the relative motion relation of circular motion.The weak point of She Zhiing is like this: when the movable body on the disk moved in a circle, its projection was experienced by people's eyesight, and projection is not directly perceived.Simultaneously, can not realize the continuous synchronization motion of single pendulum bead and movable body lateral projection ideally.Do not have image to draw mechanism in addition, can't draw motion video, thereby just can not do quantitatively measuring and calculating and analysis yet.Above-mentioned these factor affecting teaching efficiency.
The purpose of this utility model overcomes the deficiencies in the prior art just, and it is directly perceived to manufacture a kind of observation motion projection, the demonstration teaching aid of single pendulum bead and motion of pointer continuous synchronization and additional visual rendering enginer structure.
The purpose of this utility model is to realize like this.This device comprises that movement display part, mechanical driving part and image describe part.Movement display partly comprises pointer, disk, single pendulum ball and luminotron.Mechanical driving part comprises motor, turbine worm, gear, belt pulley, guide rail and guide plate.Image drawing section branch comprises paper feed roller, paintbrush, recording paper strip.Movement display part and mechanical driving part are separated by median septum.Carousel gear drives guide plate by driving lever and moves as horizontal translation along guide rail, and pointer joins by web joint and guide plate.When the guide plate translation motion, the pointer of front is translation motion synchronously also.Pointer, disk, single pendulum ball and luminotron are in same movement vision plane.Single pendulum is stone-dead when doing, and locatees by electromagnetic actuation.When pointer moves to the relevant position, the outage of control electromagnet, the single pendulum ball just can be synchronized with the movement in company with pointer.Electromagnet is arranged on the accessible solstics of the beat of pointer.Disk is coaxial with carousel gear, and when carousel gear was rotated, disk rotated simultaneously.The intersection point of radius and circumference is positioned on the vertical plane at pointer place all the time on the disk.But paintbrush is installed on the web joint of translation motion, and paper feed roller is by belt gear, and the activation record paper tape moves.Harmonic motion between paintbrush (being synchronized with the movement with luminotron, pointer) and paper tape at the uniform velocity advance and combine, and just can draw out sinusoidal curve.
The utlity model has following advantage:
1. each part of movement display part places in the same visual plane, and pointer (projection line), luminotron (subpoint), paintbrush and single pendulum ball all swing continuously by sinusoidal rule, and the demonstration effect is directly perceived, and classroom teaching effect is good.
2. describe part owing to be provided with image, can write down the sine line of a harmonic motion, this figure line can be for the essence of measuring and calculating and reflection sine principle.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
Fig. 1 is a schematic appearance of the present utility model.
Fig. 2 is that image of the present utility model is described structural scheme of mechanism.
