Abstract
The utility model relates to a teaching appliance, in particular to a four-rod mechanism teaching appliance. The four-rod mechanism teaching appliance has the improvement of comprising a rod piece 1, a rod piece 2, a rod piece 3, a rod piece 4, rod piece 5 and rod piece 6 with different lengths as well as a sliding block 7 and a connecting piece 8; the two ends of each rod piece are respectively provided with a hole; the sliding block 7 is hollow and one side of the sliding block 7 is also provided with a hole. As the rod pieces and the sliding of the teaching appliance can be conveniently mounted and dismounted and the length and the number of the rod piece are set according to the need. The utility model is suitable for the lecture of the teacher and the experiment of the student, and can be intuitively and rapidly mounted to demonstrate various four-rod mechanisms and the motion trail.
Description
Technical field
The utility model relates to a kind of teaching aid, especially relates to a kind of four-bar mechanism teaching aid.
Background technology
At present, in " mechanical principle " course learning,, lack the type of energy ocular demonstration four-bar mechanism and the teaching aid of kinetic characteristic thereof, be unfavorable for that the student grasps content fast about the teaching of four-bar mechanism content.
Summary of the invention
The purpose of this utility model just provides a kind of novel four-bar mechanism teaching aid, makes it can demonstrate the assembling and the kinetic characteristic thereof of four-bar mechanism fast.
The purpose of this utility model is realized by following technical scheme: this four-bar mechanism teaching aid, its improvements are that it comprises each unequal rod member 1 of length, rod member 2, rod member 3, rod member 4, rod member 5, rod member 6 and slide block 7, web member 8; The two ends of described each rod member respectively are provided with a hole; Described slide block 7 is a hollow, and also is provided with a hole on the side of slide block 7.
Above-mentioned four-bar mechanism teaching aid, the thickness of described each rod member are 1mm～2mm.
Because rod member, the slide block dismounting easily of this teaching aid, and the length of rod member, quantity are set as required, therefore be fit to very that the teacher teaches, the student makes experiment, can be intuitively, promptly assemble, demonstrate various four-bar mechanisms and kinetic characteristic thereof.
