Abstract
The utility model discloses a multifunctional mechanics teaching demonstrator, and relates to the field of mechanics teaching. A connection bracket (2) is arranged above one side face of a base (1) through a fixing plate (3); a ball clamping device (4) is arranged above the connection bracket (2); a sliding slot (7) is arranged on the side edge of the base (1); one end of a scaleplate (6) is connected with the sliding slot (7) in a sliding manner; a baffle (5) is arranged above the scaleplate (6); bottom wheels (8) are arranged at the bottom of the base (1); a fixing screw (9) is arranged above the other side face of the base (1) and is connected with a first pulley (10) and a second pulley (11) through a pull rope; and weights (12) are connected below the first pulley (10) and the second pulley (11). The multifunctional mechanics teaching demonstrator is simple in structure and rational in design, is suitable for various experimental mechanics demonstrations, is small in size and light in weight, is convenient to carry and operate and can help students to understand the mechanics principle.
Description
Technical field:
The utility model relates to a kind of mechanics teaching field, is specifically related to a kind of multi-functional mechanics teaching demonstration device.
Background technology:
The mechanics of physics the inside is very abstract subject, the student can't see the variation of mechanics under different situations clearly intuitively in learning process, therefore mechanics is difficult to understand, and also can make the student produce uninteresting psychology, general teacher can manually test in the process of imparting knowledge to students and help the student and understand, existing mechanics teaching demonstration device is divided into many types, the teacher need to bring various education demonstrators when carrying out the mechanics demonstration and demonstrate, very trouble does not also find that a cover is fit to the equipment of multiple mechanics teaching demonstration at present.
The utility model content:
The purpose of this utility model provides a kind of multi-functional mechanics teaching demonstration device, and it is simple in structure, and is reasonable in design, is fit to the demonstration of kinds of experiments mechanics, and its volume is little, and is lightweight, is convenient for carrying operation, can better help the student to understand mechanics principle.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises pedestal 1, connection bracket 2, fixed head 3, ball-clamped device 4, baffle plate 5, scale 6, chute 7, return pulley 8, gib screw 9, the first pulley 10, the second pulley 11 and counterweight 12, the top, one side of pedestal 1 is provided with connection bracket 2 by fixed head 3, the top of connection bracket 2 is provided with ball-clamped device 4, be provided with chute 7 on the side of pedestal 1, one end and the chute 7 of scale 6 are slidingly connected, and the top of scale 6 is provided with baffle plate 5, the bottom of pedestal 1 is provided with return pulley 8, the top, another side of pedestal 1 is provided with gib screw 9, gib screw 9 by stay cord and the first pulley 10 be connected pulley 11 and be connected, the below of the first pulley 10 and the second pulley 11 is connected with counterweight 12.
Gripping transfer paper on the described baffle plate 5.
The demonstration of the applicable level throw motion mechanics demonstration of the utility model and Composition and separation of mechanics.
When the utility model carried out the demonstration of level throw motion mechanics, ball-clamped device 4 discharged bead, and bead is done level throw motion, and the transfer paper of the baffle plate 5 above scale 6 stays the marking, then with scale 6 downward modulations, tested again.
The utlity model has following beneficial effect: it is simple in structure, and is reasonable in design, is fit to the demonstration of kinds of experiments mechanics, and its volume is little, and is lightweight, is convenient for carrying operation, can better help the student to understand mechanics principle.
