Abstract

The utility model discloses a hinged four-rod mechanism type demonstration device comprising four connecting rods with unequal lengths; the four connecting rods are hinged to form a four-bar linkage; two pin holes are arranged on each connecting rod; the device also comprises a baseboard; fixed holes corresponding to the pin holes of each connecting rod are arranged on the baseboard; and two pins respectively penetrate in the pin holes of one connecting rod to fix the connecting rod with the baseboard together. The hinged four-bar linkage type demonstration device provided by the utility model is simple in structure, intuitive in demonstration, convenient for understanding and mastery of students, and conducive to improving the classroom teaching effect.

Description

Four-bar linkage type apparatus for demonstrating
Technical field:
The utility model relates to a kind of four-bar linkage type apparatus for demonstrating, is used to demonstrate the movement characteristic of four-bar linkage type.
Background technology:
In the course of professor's mechanical principle, when needing demonstration four-bar linkage kinds of athletic characteristics, owing to there is not corresponding apparatus for demonstrating, teaching is relatively wasted time and energy.
Summary of the invention:
The purpose of this utility model provides a kind of four-bar linkage type apparatus for demonstrating, solves the defective that does not have corresponding apparatus for demonstrating and teaching is relatively wasted time and energy.
The purpose of this utility model realizes as follows: this four-bar linkage type apparatus for demonstrating comprises four not isometric connecting rods, four connecting rod links constitute four-bar mechanism, two pin-and-holes are arranged on each connecting rod, other has a base plate, the fixed orifice that corresponding each connecting rod pin-and-hole is arranged on the base plate has in two pin-and-holes that penetrate one of them connecting rod the pin that this connecting rod and base plate are fixed together.
This device is used to demonstrate under the constant situation of four length of connecting rods, be fixed on the base plate back with different connecting rods by pin as frame, demonstrate three kinds of different hinge four-bar kinds of athletic characteristics, can demonstrate crank and rocker mechanism movement characteristic, double-crank mechanism movement characteristic, double rocker mechanism movement characteristic respectively.
The utility model is simple in structure, and student's understanding and grasp are convenient in demonstrating visual, help to improve classroom teaching effect.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
