Description
Technical field
The utility model relates to a kind of physics facility, especially a kind of conservation of mechanical energy test test block reduction gear.
Background technology
In current Physical Experiment, the apparatus for demonstrating for experiment with falling objects generally adopts a manually hand-held Metal Ball, is not being considered under friction condition by the process of gravitional force to kinetic transformation by the let-down of Metal Ball without speed afterwards to demonstrate Metal Ball.
But owing to there is no reduction gear in presentation process, and the quality of Metal Ball is larger, the damage on ground is easily caused in the process on ground that drops, and sound can be there is when dropping and tumbles everywhere in Metal Ball, thus the classroom discipline affected in classroom, even also can cause bad impact to the order of attending class in other classrooms.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one to prevent Metal Ball from tumbling, and reduces noise occurs, a kind of conservation of mechanical energy test test block reduction gear can also demonstrated Lenz law.
The utility model is achieved through the following technical solutions:
A kind of conservation of mechanical energy test test block reduction gear, it is characterized in that: the copper pipe comprising an inner hollow both ends opening, this inner edge, copper pipe upper end uniform intervals makes multiple spring leaf, gap is formed between multiple described spring leaf medial end, a magnet piece is installed with in this gap, this magnet piece is suspended at the upper end of copper pipe, is shaped with the catching device for accepting Metal Ball in the copper pipe above described magnet piece.
And, described catching device comprises one for accepting the metal bowl of Metal Ball, the external diameter of this metal bowl is less than the gap formed between multiple described spring leaf medial end, is separately installed with the both side ends of a stage clip in the lower surface of described metal bowl and the upper surface of described magnet piece.
And described copper pipe bottom outer rim is shaped with a polypody support, is shaped with a foam-rubber cushion between the stempoda of described polypody support, the opening phase contraposition that this foam-rubber cushion and described copper pipe bottom are made.
Advantage of the present utility model and good effect are:
In the utility model, copper pipe coordinates spring leaf, magnet piece and catching device, and can carry out undertaking to the Metal Ball demonstrated and slow down, avoid because Metal Ball speed is excessive, that causes after directly falling to ground tumbles problem; Wherein the metal bowl of catching device effectively can accept Metal Ball, kinetic energy after Metal Ball can be fallen by the stage clip of its lower surface conducts on magnet piece, make magnet piece, catching device and Metal Ball are dropped by the state suspended, in the process of dropping, induction field that magnet produces in hollow copper pipe stops dropping of magnet to be slowed down, and therefore not only reaches the object that Metal Ball above to magnet and catching device slow down in moderating process, but also demonstrates Lenz law; The support assorted foam-rubber cushion made below copper pipe can by the Metal Ball after slowing down through copper pipe, and magnet piece and catching device carry out energy-absorbing, avoid the problem causing Metal Ball to tumble under the effect of remaining kinetic energy, thus reduces the noise that occurs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Elaborate to the utility model below by embodiment, described embodiment is illustrative, and nonrestrictive, can not limit protection domain of the present utility model with this.
A kind of conservation of mechanical energy test test block reduction gear, the utility model innovation is, comprise the copper pipe 4 of an inner hollow both ends opening, the radial uniform intervals in this inner edge, copper pipe upper end makes multiple spring leaf 7, gap is formed between multiple described spring leaf medial end, be installed with a magnet piece 3 in this gap, this magnet piece is suspended at the upper end of copper pipe, is shaped with the catching device for accepting Metal Ball in the copper pipe above described magnet piece.
Described catching device comprises one for accepting the metal bowl 1 of Metal Ball, the external diameter of this metal bowl is less than the gap formed between multiple described spring leaf medial end, is separately installed with the both side ends of a stage clip 2 in the lower surface of described metal bowl and the upper surface of described magnet piece.
Described copper pipe bottom outer rim is shaped with a polypody support 6, is shaped with a foam-rubber cushion 5 between the stempoda of described polypody support, the opening phase contraposition that this foam-rubber cushion and described copper pipe bottom are made.
Use procedure of the present utility model is:
When the utility model uses, first reduction gear is vertically placed in flat bottom surface with polypody support, user only need by original experiment method afterwards, and by the lowered position of Metal Ball and the metal bowl position phase contraposition in reduction gear, after let-down Metal Ball, Metal Ball arrives in metal bowl, its kinetic energy can carry out preliminary absorption and conduction by catching device, owing to being applied with downward power to magnet piece, magnet piece, drop in the gap that Metal Ball and catching device can be made by spring leaf medial end, in the process of dropping, magnet piece defines induction field to copper pipe, according to Lenz law, induction field can play inhibition to magnet piece, thus reach the object of deceleration, final being fallen in foam-rubber cushion by the underpart opening of copper pipe completes whole experimentation.
In the utility model, copper pipe coordinates spring leaf, magnet piece and catching device, and can carry out undertaking to the Metal Ball demonstrated and slow down, avoid because Metal Ball speed is excessive, that causes after directly falling to ground tumbles problem; Wherein the metal bowl of catching device effectively can accept Metal Ball, kinetic energy after Metal Ball can be fallen by the stage clip of its lower surface conducts on magnet piece, make magnet piece, catching device and Metal Ball are dropped by the state suspended, in the process of dropping, induction field that magnet produces in hollow copper pipe stops dropping of magnet to be slowed down, and therefore not only reaches the object that Metal Ball above to magnet and catching device slow down in moderating process, but also demonstrates Lenz law; The support assorted foam-rubber cushion made below copper pipe can by the Metal Ball after slowing down through copper pipe, and magnet piece and catching device carry out energy-absorbing, avoid the problem causing Metal Ball to tumble under the effect of remaining kinetic energy, thus reduces the noise that occurs.
