Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Depend on Figure 1 to Figure 13 Provide, the present invention comprises horizontal plate 1, and the left and right ends of plate 1 lower side are fixed with vertical riser 2, the outside of every riser 2 has the first riser, the inboard of each riser 2 has The second vertical board is connected and fixed together with the lower end of the first vertical board to form a U-shaped frame 3 with an upward opening. The lower end of the vertical board 2 is inserted into the cavity of the U-shaped frame 3, and the U-shaped frame 3 can slide up and down along the vertical plate 2, and the U-shaped frame 3 can be fixed at any height on the vertical plate 2;

[0025] Each of the U-shaped plates has a first rack 4 that can slide up and down along the second vertical plate. There is a large gear 5 between the two first rack...

Abstract

The invention provides a leveling device for a momentum conservation experiment, solves the problem that the initial speed of a small ball during the collision of the momentum conservation experimentis not horizontal, avoids influence, caused by the fact that an experiment platform is not horizontal, on the experiment and lowers interference, caused by human factors, to the experiment. Accordingto the technical scheme, the leveling device comprises a flat plate and is characterized in that vertical plates are arranged below the flat plate, a first vertical plate is arranged on each verticalplate, a second vertical plate is arranged on each vertical plate, and each second vertical plate and the corresponding first vertical plate form a U-shaped frame; each U-shaped frame is provided witha first rack, a bull gear is arranged between the two first racks, pinions are arranged on two sides of each first rack, second racks are arranged on one sides of the pinions, slide plates are arranged on the outer sides of the second racks and provided with first positioning pins and second positioning pins, and a counter weight is arranged below the bull gear. The leveling device is novel in concept, ingenious in structure, capable of guaranteeing that the initial speed of the small ball in the momentum conservation experiment is horizontal, capable of increasing the precision of the experiment, capable of reducing influence, caused by the human factors, on the experiment, capable of lowering the leveling difficulty of the experiment, high in practicality and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of high school physics experiment devices, in particular to a leveling device for momentum conservation experiments. Background technique [0002] At present, the experimental equipment used in high schools to verify the conservation of momentum is to verify the law of conservation of momentum by using a small ball that rolls down an inclined rail to collide with a small ball that is stationary on a horizontal orbit. The experiment requires that the colliding ball and the collided ball be ejected from the horizontal track, which requires the instrument to be horizontal. However, existing experimental instruments do not have the function of adjusting the level. If the experimental table is not level, the ball will not be thrown flat in the air, which will bring a large systematic error to the experiment. [0003] For this reason, the present invention provides a leveling device for momentum conservation exp...
