Description
Technical field
The utility model relates to a kind of multifunctional slipper magnetic force impinger, belongs to momentum conservation education experiment technical field.
Background technology
At present, known physics momentum conservation experiment slide block impinger has two kinds, and one makees perfectly elastic impact device by turn, and one does perfect inelastic collision by velcro, plasticine or putty.But all there is following shortcoming in these two kinds of impingers of background technology: does elastic collision with turn and be easily out of shape fatigue, follow the string; Do perfect inelastic collision bonding force with velcro, plasticine or putty poor, make trouble, collision effect is bad and the life-span is short.
Utility model content
The utility model object is to provide a kind of multifunctional slipper magnetic force impinger, can not only complete two kinds of typical crash, and structure is simply easy to use, and the life-span is permanent, solves Problems existing in background technology.
The technical solution of the utility model is:
A kind of multifunctional slipper magnetic force impinger, comprises slide block, light barrier, hold-down nut, base, strong magnets, photoelectricity door, air track, digital counter and air pump; Slide block is provided with light barrier, and the end of slide block is provided with bolt hole; Base is U-shaped structure, and A/F and the slide block width of U-shaped structure match, and the U-shaped structure of base is stuck in the end of slide block, base and slide block are fixed together by hold-down nut and bolt; Strong magnets is arranged on the bottom outer of base U-shaped structure, and strong magnets is positioned at whole slide block foremost; Two above-mentioned slide blocks are arranged on the two ends of air track, and air track is provided with two photoelectricity doors, and two photoelectricity doors are connected with digital counter; Air track surface is provided with multiple pore, and air track connects air pump.
The bottom outer of described base U-shaped structure is provided with draw-in groove, and strong magnets is stuck in draw-in groove.
Described base is aluminium alloy magnet base.
Pressurized air is sent into air track inner chamber by air pump, air is sprayed by the pore on air track surface again, very thin air cushion layer is formed between air track surface and slide block inside surface, slide block just floats on air cushion layer, disengage with the rail level of air track, thus can do approximate non-resistance rectilinear motion on the rail level of air track.The collision of two slide block move toward one another, the light barrier on slide block is through photoelectricity door, and speed, respectively by digital timer record, so just obtains the momentum of former and later two slide blocks of collision, therefore can verify striking momentum whether conservation.
The beneficial effects of the utility model are: multi-functionally can complete slide block elasticity and non-resilient two kinds of collisions, structure is simply easy to use, and the effective life-span is long.

Fig. 3 is the utility model example structure figure;
In figure: slide block 1, light barrier 2, hold-down nut 3, base 4, strong magnets 5, photoelectricity door 6, air track 7, digital counter 8, air pump 9.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
A kind of multifunctional slipper magnetic force impinger, comprises slide block 1, light barrier 2, hold-down nut 3, base 4, strong magnets 5, photoelectricity door 6, air track 7, digital counter 8 and air pump 9; Slide block 1 is provided with light barrier 2, and the end of slide block is provided with bolt hole; Base 4 is U-shaped structure, and A/F and the slide block width of U-shaped structure match, and the U-shaped structure of base 4 is stuck in the end of slide block, base and slide block are fixed together by hold-down nut 3 and bolt; Strong magnets 5 is arranged on the bottom outer of base 4U shape structure, and strong magnets 5 is positioned at whole slide block foremost; Two above-mentioned slide blocks are arranged on the two ends of air track 7, and air track 7 is provided with two photoelectricity doors, 6, two photoelectricity doors 6 and is connected with digital counter 8; Air track 7 surface is provided with multiple pore, and air track 7 connects air pump 9.
The bottom outer of described base 4U shape structure is provided with draw-in groove, and strong magnets 5 is stuck in draw-in groove.
Pressurized air is sent into air track 7 inner chamber by air pump 9, air is sprayed by the pore on air track surface again, very thin air cushion layer is formed between air track surface and slide block 1 inside surface, slide block 1 just floats on air cushion layer, disengage with the rail level of air track, thus can do approximate non-resistance rectilinear motion on the rail level of air track.The collision of two slide block move toward one another, the light barrier 2 on slide block is when photoelectricity door 6, and speed, respectively by digital timer 8 record, so just obtains the momentum of former and later two slide blocks of collision, therefore can verify striking momentum whether conservation.
Hold-down nut is fixed on base on slide block, and base fixes strong magnets, and strong magnets is placed in the draw-in groove of base.When needs elastic collision, the strong magnets same sex is arranged on two relative slide blocks relatively respectively, during two slide block move toward one another then due to magnet two like magnetic poles repel each other operating distance very near time elasticity separately; When needs inelastic collision, then the strong magnets opposite sex is relatively arranged on two relative slide blocks respectively, during two slide block move toward one another, then due to magnet, there is a natural attraction between the sexes that effect bonds together, and completes inelastic collision.
Described base is aluminium alloy magnet base, and the draw-in groove before base is convenient to strong magnets placement and is taken out, and only needs the magnetic pole of switching combining two strong magnets when elastic collision and inelastic collision switch, simple and convenient.
