Abstract
The utility model discloses a new type horizontal projectile motion demonstration instrument. The new type horizontal projectile motion demonstration instrument is mainly composed of a small magnetic ball, a drawable baffle, a sliding chute and a vertical flat plate. The sliding chute is fixed at the upper left side of the vertical flat plate; the top end of the sliding chute is designed with a small hole for the drawable baffle; grid lines are carved onto the surface of the vertical flat plate; the vertical flat plate is composed of trace reservation holes and a base; and each trace reservation hole is composed of a silver surface layer, a reed switch, a small ultraviolet lamp bead and connecting wires. According to the utility model, characteristics, such as simple design, durability, etc., can be realized.
Description
Technical field
The utility model relates to a kind of demonstration instrument for teaching, relates in particular to a kind of novel flat throwing demonstrator.
Background technology
Although the track of existing flat throwing demonstrator energy demonstrating level throw motion is difficult for being retained on two vertical plates, such instrument is unfavorable for teaching, is unfavorable for simultaneously quantitatively probing into the rule of level throw motion.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to propose a kind of novel flat throwing demonstrator, thisly not only the phenomenon of level throw motion can be represented to the student, can be easy to contrail of motion is stayed on two vertical plates simultaneously, conveniently impart knowledge to students and study.
To achieve these goals, the technical solution adopted in the utility model is such: it mainly is comprised of magnetic ball, pull baffle plate, chute and two vertical plates; Chute is fixed on the upper left side of two vertical plates; The tip designs of chute is by the aperture of a pull baffle plate; Mesh lines is carved with on the surface of two vertical plates; Two vertical plates keeps aperture by vestige and base forms; Vestige keeps aperture by silver-colored light top layer, tongue tube, ultraviolet small lamp bulb and is connected wire and forms.
Useful technique effect of the present utility model is: vertical baffle is designed to keep by a plurality of vestiges the baffle plate that aperture forms in design, vestige keeps aperture by silver-colored light top layer, tongue tube, ultraviolet small lamp bulb and is connected wire and forms, such design can utilize the characteristics of tongue tube, switch on power in the magnetic ball process, the ultraviolet ray small lamp bulb is luminous, so just stays the position of bead process on vertical baffle; At the tip designs of the chute aperture by a pull baffle plate, such design can determine that the height that bead descends is unique.
Description of drawings
Fig. 1 is schematic perspective view of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Structure of the present utility model is: it mainly is comprised of magnetic ball (1), pull baffle plate (2), chute (3) and two vertical plates (4); Chute (3) is fixed on the upper left side of two vertical plates (4); The tip designs of chute (3) is by the aperture of a pull baffle plate (2); Mesh lines is carved with on the surface of two vertical plates (4); Two vertical plates (4) keeps aperture (41) by vestige and base (42) forms; Vestige keeps aperture (41) by silver-colored light top layer (411), tongue tube (412), ultraviolet small lamp bulb (413) and is connected wire (414) and forms.
At first the utility model loads onto battery when in use, then be placed on the operator's console of level, then magnetic ball (1) is placed on chute (3), be fixed on chute (1) with pull baffle plate (2), pull out pull baffle plate (2) and discharge magnetic ball (1), in the position that bead passes through, tongue tube (412) is connected circuit, ultraviolet ray small lamp bulb (413) is luminous, silver light top layer (411) is luminous with the long period, write down with marking pen the position that luminous vestige keeps aperture (41), the rule that last research institute has a few gets final product.
