The invention has the beneficial effects as follows,
The present invention can image demonstration convert rotational motion be rectilinear motion by bar linkage structure, coordinated by rack and pinion, be rotary motion by transform linear motion, coordinate finally by gear, second connecting rod and slide block, be rectilinear motion by convert rotational motion again, be conducive to understanding and the study of student by the be connected teaching aid of the present invention that formed of various structures.
Accompanying drawing explanation
Fig. 1 is the structural representation of mechanical linkage motion principle demonstration teaching aid provided by the invention.
Embodiment
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1 is shown a kind of mechanical linkage motion principle demonstration teaching aid provided by the invention, comprising: installing plate 1, rotating shaft 2, swing arm 3, chute 4, swingle 5, tooth bar 6, gear 7, second connecting rod 8, slide block 9, orienting lug 10 and first connecting rod 11.Described installing plate 1 is rotatably provided with rotating shaft 2, and rotating shaft 2 is provided with swingle 5; Described installing plate 1 is provided with swing arm 3, swing arm 3 offers chute 4, and swingle 5 end and swing arm 3 are connected through chute 4 by bolt; One end and the installing plate 1 of described swing arm 3 are rotatably connected, and the other end has been rotatably connected first connecting rod 11; Described installing plate 1 is provided with tooth bar 6, and tooth bar 6 is slidably arranged on installing plate 1; Described first connecting rod 11 is rotatably connected away from one end of swing arm 3 and tooth bar 6; Described installing plate 1 is provided with the gear 7 be connected with tooth bar 6; Described installing plate 1 is provided with orienting lug 10, orienting lug 10 offers gathering sill, is provided with the slide block 9 be mated, is provided with second connecting rod 8 between slide block 9 and gear 7 in gathering sill, one end and the gear 7 of second connecting rod 8 are rotatably connected, and the other end and slide block 9 are rotatably connected; Described gathering sill is positioned at directly over gear; Described rotating shaft 2 is provided with the drive unit driving it to rotate; Described drive unit is motor; Described drive unit is rotary handle.
Principle of work: swingle 5 is rotated by drive unit, because swingle 5 and swing arm 3 are connected by the chute 4 of bolt and swing arm 3, swing arm 3 is swung, thus make first connecting rod 11 pull tooth bar 6 to do linear reciprocating motion, the rotary motion of tooth bar 6 driven gear 7, pulls slide block 9 to do linear reciprocating motion along the gathering sill of orienting lug 10 by second connecting rod 8 when gear 7 rotates.
Vividly can demonstrate convert rotational motion by bar linkage structure be rectilinear motion, coordinated with gear 7 by tooth bar 6, be rotary motion by transform linear motion, coordinate finally by gear 7, second connecting rod 8 and slide block 9, be rectilinear motion by convert rotational motion again, be conducive to understanding and the study of student by the be connected teaching aid of the present invention that formed of various structures.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
