Abstract
A mechanics analysis demonstrator, which belongs to a teaching instrument, mainly solves the problem on how to enable students to visually comprehend stress analysis. The mechanics analysis demonstrator comprises a demonstrator body, which comprises a supporting pole with a base and two inclined tubes, fixing holes are longitudinally distributed side by side on the supporting pole, each inclined tube comprises an outer tube, inner tubes and a spring, the inner tubes are respectively movably inserted into both ends of the outer tube, the spring is connected between the two inner tubes positioned in the same outer tube, the surface of each inner tube is provided with size graduations, the inner tube of one end of each of the two inclined tubes is connected with the supporting pole through a movable pin shaft, and the inner tubes of the other ends are connected together through a movable pin shaft and provided with a hanging ring. The structure of the mechanics analysis demonstrator is simple, and the mechanics analysis demonstrator is convenient to use, and can scientifically and accurately demonstrate the stress of each side by means of angle change, so that people can visually know and comprehend mechanics-related knowledge.
Description
Technical field
The utility model relates to a kind of instruments used for education, specifically a kind of mechanical analysis demonstration device.
Background technology
In learning physics class triangle force analysis, owing to institute gains knowledge too abstract, the student is difficult to understand fully by teacher's language description, and lack at present suitable teaching aid, can't allow the student produce comparatively directly perceived, vivid understanding and understanding, bring certain influence for teacher's teaching and student's study.
The utility model content
The purpose of this utility model is to provide a kind of mechanical analysis demonstration device, and this demonstration device can easily be learnt the complicated principle of force analysis by simple structural change.
The technical scheme in the invention for solving the technical problem is: a kind of mechanical analysis demonstration device, comprise the demonstration device body, it is characterized in that, described demonstration device body is made of the support bar that has base and two inclined tubes, vertically be distributed with fixed orifice on the support bar side by side, inclined tube is made of outer tube, interior pipe and spring, the movable respectively two ends of inserting outer tube of described interior pipe, spring is connected between two interior pipes in same outer tube, and interior tube-surface is provided with the size scale line; The interior pipe of two inclined tube one ends is connected on the support bar, and the interior pipe of the other end is connected to each other and is provided with suspension ring, and each tie point place is connected by active pin shaft respectively.
The beneficial effects of the utility model are: simple in structure, easy to use, can science demonstrate the stressing conditions on each limit by the angle variation exactly, and allow people be familiar with the mechanics relevant knowledge intuitively, be convenient to people's understanding.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 support bar, 2 fixed orifices, 3 bases, 4 outer tubes, 5 bearing pins, 6 interior pipes, 7 suspension ring.
Embodiment
As shown in Figure 1.A kind of mechanical analysis demonstration device, comprise the demonstration device body, described demonstration device body is made of the support bar 1 that has base 3 and two inclined tubes, vertically be distributed with fixed orifice 2 on the support bar 1 side by side, inclined tube is made of outer tube 4, interior pipe 6 and spring, the respectively movable two ends of inserting outer tubes 4 of pipe 6 in described, spring are connected in same outer tube 4 in two and manage between 6, and interior pipe 6 surfaces are provided with the size scale line; The interior pipe of two inclined tube one ends is connected on the support bar 1, and the interior pipe of the other end is connected to each other and is provided with suspension ring 7, and each tie point place is connected by active pin shaft 5 respectively.
When inclined tube was subjected to pulling force, the scale part of interior pipe 6 was elongated; When inclined tube was under pressure, the scale of interior pipe 6 partly shortened, the variation of size scale line, and what demonstrate intuitively that inclined tube is subjected to is pulling force or pressure.A plurality of fixed orifices 2 are set on the support bar 1, can make inclined tube can change position and angle up and down, thereby change stressed size.The utility model is simple in structure, and is easy to use, can science changes by angle exactly demonstrate the stressing conditions on each limit, allows people be familiar with intuitively and understands the mechanics relevant knowledge, is particularly useful for the school instruction use.
