Description
Technical field
The utility model relates to a kind of teaching aid, relates in particular to the teaching demonstration device of a kind of flat throwing and the movement of falling object.
Background technology
The characteristics of motion of flat paraboloid may be summarized to be 2 points: the one, and horizontal direction is done linear uniform motion; The 2nd, vertical direction is done the movement of falling object; Can be the contrast experiment of the flat throwing and the movement of falling object for the motion of studying flat paraboloid; Two objects are put down respectively simultaneously throw and freely falling body, two articles falls earthward simultaneously, explains that the vertical componental movement of flat paraboloid is identical with the falling of freely falling body object.Need compare demonstration to the flat throwing and the movement of falling object with apparatus for demonstrating during classroom instruction.
The utility model content
The purpose of the utility model provides a kind of flat throwing and movement of falling object apparatus for demonstrating, conveniently the level throw motion and the movement of falling object is carried out teaching demonstration.
The utility model is that the technical scheme that its technical matters of solution is adopted is,
The flat throwing and movement of falling object apparatus for demonstrating comprises a vertical magnetic sheet that is provided with, and said magnetic sheet is provided with web joint, and this web joint is provided with reed; The reed top is fixed on the web joint, and separate with web joint its bottom, and the reed both sides are respectively equipped with clamping plate and bearing; Have a spheroid between reed and the clamping plate, reed compresses this spheroid, and it is suspended from the space between reed and the clamping plate; Be placed with another spheroid on the bearing, be hung with a lance on the web joint, this lance is positioned at the clamping plate top; The head points reed of lance also is provided with a strip and connects the thing groove on the said magnetic sheet, this connects the thing groove and is positioned at the web joint below;
Said web joint top has an Extendible flake, and this Extendible flake is vertical with web joint, and said reed is connected the lower surface of Extendible flake;
Said web joint with connect the thing groove and be equipped with kicker magnet, web joint and connect the thing groove and be adsorbed in the magnetic sheet surface through kicker magnet.
The advantage of the utility model is; This apparatus for demonstrating is located at lance and spheroid on a plate; Each component layouts is compact, assemble easily during use, and web joint with connect the thing groove and all be adsorbed on the magnetic sheet through kicker magnet; The convenient adjusting connects the distance between thing groove and the spheroid, and lecture experiment can carry out as required flexibly.
Description of drawings
Fig. 1 is the flat throwing of the utility model proposition and the structural representation of movement of falling object apparatus for demonstrating.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
Magnetic sheet 1 as shown in Figure 1, that flat throwing that the utility model proposes and movement of falling object apparatus for demonstrating include vertical setting, said magnetic sheet 1 is provided with web joint 2; This web joint 2 is provided with reed 21, and reed 21 tops are fixed on the web joint 2, and separate with web joint its bottom; Reed 21 both sides are respectively equipped with clamping plate 22 and bearing 23, have a spheroid 221 between reed 21 and the clamping plate 22, and reed 21 compresses this spheroid 221; It is suspended from the space between reed 21 and the clamping plate 22, is placed with another spheroid 231 on the bearing 23, be hung with a lance 24 on the web joint 2; This lance 24 is positioned at clamping plate 22 tops; 21 of the head points springs of lance 24 also are provided with a strip on the said magnetic sheet 1 and connect thing groove 3, and this connects the below that thing groove 3 is positioned at web joint 2; Said web joint 2 tops have an Extendible flake 211, and this Extendible flake 211 is vertical with web joint 2, and said reed 21 is connected the lower surface of Extendible flake 211; Said web joint 2 with connect thing groove 3 and be equipped with kicker magnet, web joint 2 and connect thing groove 3 and be adsorbed in magnetic sheet 1 surface through kicker magnet.
This apparatus for demonstrating is located at lance and spheroid on a plate; Each component layouts is compact, assemble easily during use, and web joint with connect the thing groove and all be adsorbed on the magnetic sheet through kicker magnet; The convenient adjusting connects the distance between thing groove and the spheroid, can carry out lecture experiment flexibly.
More than show and described the advantage of ultimate principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
