Abstract
The utility model relates to a device which can show centrifugal force role, which is characterized in that the device comprises a base, an operation part and a display part. The inner of the base is provided with a fixing frame, a pair of bevel gears and a speed shifting mechanism are arranged on the fixing frame, the speed shifting mechanism is an accelerator, wherein the output end is connected with a pair of bevel gears whose output end is connected with a transmission shaft, one end of the transmission shaft is connected with a generator, other end extends into the display part. The operation part is a shaken handle, the inner end of the shaken handle is connected with the speed shifting mechanism. The display part comprises a transparent cover, a pair of fixed seat and at least a bouquet of elastic steel strip. One of a pair of fixed seat is fixedly arranged on top of the transmission shaft which extends into the transparent cover, other is sleeved on the transmission shaft. At least one bouquet of elastic steel strip is arranged between two fixed seats. When the visitor shakes the handle, the elastic steel strip beam is driven to rotate by the rotary mechanism; the two ends of the steel strip beam are acted on by the centrifugal force to form a variation of ellipse, the greater the speed is, the larger the centrifugal force is, and the flatter the ellipse is. The device shows the effect of the centrifugal force from the mechanics and the optics.
Description
Technical field
The utility model relates to a kind of device that shows centrifugal action.
Background technology
The device of existing demonstration centrifugal action is generally based on nicknack, and it adopts clockwork spring as power, because its volume is little, actuation time is fast, therefore shows that centrifugal action is not obvious.
Summary of the invention
The purpose of this utility model is in order to overcome the existing shortcoming that shows the device of centrifugal action, and provide a kind of large-scale, simple in structure, can show the centrifugal force effect from mechanics and optics, be fit to the science that scientific exhibit participates in for the visitor and the device of the recreational demonstration centrifugal action that combines.
The purpose of this utility model is achieved in that the device that shows centrifugal action, is characterized in, comprises a base, a functional unit and a display unit;
Described base comprises a cylindrical shell, be provided with fixed mount in it, fixed mount is provided with an a pair of crowngear and a gear, described gear is a speed-increasing gear, its output terminal is connected with described a pair of crowngear, the output terminal of this crowngear connects a transmission shaft, and this transmission shaft one end is connected with generator, and the other end extend in the display unit;
Described functional unit is a crank handle, and the inner end of this crank handle is connected with the input end of gear;
Described display unit comprises a translucent cover, and this translucent cover is located at the base top, is provided with a pair of holder and a branch of at least flexible strip in it; In the described a pair of holder, one of them is installed in the propeller section top of stretching in this translucent cover, and another is set on this propeller section; Described a branch of at least flexible strip is connected between two holders.
The device of above-mentioned demonstration centrifugal action wherein, is provided with a jaw clutch between described crank handle and the speed-increasing gear.
The device of above-mentioned demonstration centrifugal action, wherein, described display unit inherence be provided with on the transmission shaft segment section between two holders sheathed one when increasing flexible strip and press down damping and the spring of the driving force when impelling flexible strip to resile.
The device of above-mentioned demonstration centrifugal action, wherein, described display unit inner bottom part is provided with at least one light source, and this light source is connected with the output terminal of generator.
The device of above-mentioned demonstration centrifugal action, wherein, described flexible strip is colored spring steel band bundle.
The device of above-mentioned demonstration centrifugal action, wherein, described holder is a disc type.
The device of above-mentioned demonstration centrifugal action, wherein, described flexible strip is inside and outside two-layer, is connected between the holder respectively.
The device of above-mentioned demonstration centrifugal action, wherein, described translucent cover is a cylindrical shape organic glass outer cover.
The device of above-mentioned demonstration centrifugal action, wherein, described base is wooden tubular.
Because the utility model has adopted above technical scheme, the visitor shakes handle, by a cover speeder body one flexible strip Shu Xuanzhuan, because the constraint of steel band bundle two ends is subjected to centrifugal action, outwardly-bent distortion in the middle of the steel band, form the ellipse of a variation, rotating speed is big more, and centrifugal force is big more, and ellipse is flat more; In order to increase sight, the utility model connects a tech-generator below transmission shaft, and rotating speed is fast more, generated energy is big more, light is bright more.Thereby size from mechanics and optics demonstration centrifugal force.
Description of drawings
Concrete structure of the present utility model is further provided by following embodiment and accompanying drawing thereof.
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
Please participate in accompanying drawing.A kind of device that shows centrifugal action of the utility model comprises a base 1, a functional unit 2 and a display unit 3.
Base 1 comprises a wooden cylindrical shell 10.Be the frame 11 of steel in the wooden cylindrical shell 10, it is 1: 4 speed-increasing gear 12, transmission shaft 13, bearing etc. that frame is used for installing a ratio of gear.Change direction by conical insert wheels 14 between transmission shaft 13 and the speed-increasing gear 12.The top of base 1 is provided with a through hole, is provided with an axle sleeve 15 in this through hole, and stretch in display unit 3 by this axle sleeve 15 the transmission shaft upper end.
Functional unit 2 is crank handles, and its output terminal stretches in base and is connected with the input end of speed-increasing gear.
Damping when the utility model presses down in order to increase flexible strip and the driving force when impelling flexible strip to resile are provided with a spring 36 on the propeller section between the disk holder 32,33 at fixing flexible strip two ends,
The utility model connects a tech-generator 16 below transmission shaft, establish two light emitting sources (for example bulb) 17 in the transparent housing bottom, and along with rotating speed is fast more, generated energy is big more, and light emitting source 17 will be bright more, show the size of centrifugal force indirectly.By the light light and shade common centrifugal force that shows that matches with the centrifugal force size.
The utility model considers that the user stops crank handle suddenly; crank handle can continue to rotate forward under action of inertia; cause unsafe factor; so special jaw clutch 18 that between handle and speed-increasing gear, increased; in case stop to shake handle, play the safeguard protection effect by jaw clutch 18.
