Abstract
The utility model discloses an inertia centrifugal force demonstration instrument, comprising a cabinet, the inner of which is provided with a switching power supply, a motor and a motor speed regulator which are controlled by a switch and a speed regulation knob arranged on the outer part of the cabinet; the cabinet is provided with a ''Y'' shaped adjustable rack which comprises two through poles arranged in a pole inclination angle adjusting seat; the pole inclination angle adjusting seat is provided with a pole inclination angle adjusting screw which is in connection with slide blocks arranged on the poles through a slide block return spring; the bottom end of the inclination angle adjusting screw applies to the connecting part of the two poles. According to the utility model, a contact and cooperation design of the pole adjusting screw inclination angle adjusting screw and the poles is employed to overcome the disadvantages of traditional centrifugal force demonstration instruments that slide pole angles can not be adjusted and to successfully demonstrate the two factors of angle and rotating speed which influence the magnitude of the centrifugal force.
Description
Technical field
The utility model relates to a kind of inertial centrifugal force demonstrator.
Background technology
In teaching practice, often need the notion of inertial centrifugal force be described, so that observer's perceptual knowledge directly perceived is provided by demonstration.But, at present comparatively single about the demonstration equipment kind of inertial centrifugal force, and cost is higher, operability is not strong.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of strong operability is provided, and also has the inertial centrifugal force demonstrator of certain intuitive.
The inertial centrifugal force demonstrator that the utility model provides comprises cabinet, and Switching Power Supply, motor and machine governor are installed in the cabinet, by being arranged on cabinet outer switch and speed governing knob controlling; Cabinet is provided with " Y " type adjustable support, " Y " type adjustable support comprises that two perforations are arranged on the pole in the pole tilt adjustment seat, pole tilt adjustment seat is provided with pole tilt adjustment screw, and pole tilt adjustment screw is connected with slide block on being arranged on pole by the slide block retracing spring; The joint that described pole tilt adjustment screw bottom is fitted in two poles.
The utility model is simple in structure, handling safety, observing effect is directly perceived, contact matching design by pole tilt adjustment screw and pole, eliminated centrifugal force demonstrator in the past and can not regulate the weak point of litter angle, success angle and these two factors that influence the centrifugal force size of rotating speed demonstrated out.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model " Y " type adjustable support.(not regulating pole inclination angle state)
Fig. 3 is the structural representation of the utility model " Y " type adjustable support.(regulating pole inclination angle state)
Wherein: 1, cabinet, 2, switch, 3, the speed governing knob, 4, pole tilt adjustment seat, 5, pole, 6, pole tilt adjustment screw, 7, the slide block retracing spring, 8, slide block.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples only are used to the utility model is described but not are used to limit scope of the present utility model.
Referring to Fig. 1, the inertial centrifugal force demonstrator that the utility model provides comprises cabinet 1, and Switching Power Supply, motor and machine governor are installed in the cabinet 1, controls by being arranged on cabinet 1 outer switch 2 and speed governing knob 3;
Described cabinet 1 is provided with " Y " type adjustable support, " Y " type adjustable support comprises that two perforations are arranged on the pole 5 in the pole tilt adjustment seat 4, pole tilt adjustment seat 4 is provided with pole tilt adjustment screw 6, and pole tilt adjustment screw 6 is connected with slide block 8 on being arranged on pole 5 by slide block retracing spring 7;
Referring to Fig. 2 or Fig. 3, the joint that described pole tilt adjustment screw 6 bottoms are fitted in two poles.
During use,
Referring to Fig. 2 and Fig. 3, by lever principle, the set screw 6 in the adjusting pole tilt adjustment seat 4 can be used for controlling the inclination angle of pole 5.
Driving adjustable inclination angle pole 5 by adjustable speed motor moves in a circle slide block, slide block 8 is subjected to centrifugal force and off-center, centrifugal force is big more, and off-centered distance is just far away more, can study the size of object suffered centrifugal force on the inclined-plane of different rotating speeds, different angle.
Claims (1)
