Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
图1为本发明实施例中多功能教具的结构示意图,包括主尺1、第一副尺2、第二副尺3和量角装置4,主尺1、第一副尺2和第二副尺3为带有刻度线的直尺;Fig. 1 is the structural schematic diagram of multifunctional teaching aid in the embodiment of the present invention, comprises main ruler 1, first auxiliary ruler 2, second auxiliary ruler 3 and protractor 4, main ruler 1, first auxiliary ruler 2 and second auxiliary ruler Chi 3 is a ruler with scale marks;
主尺1的零刻度线处铰连接第一副尺2的零刻度线处;The zero scale line of the main scale 1 is hinged to the zero scale line of the first auxiliary scale 2;
量角装置4包括带有角度标识的尺带、壳体和鼓轮;鼓轮设置在壳体内且与壳体通过盘簧连接;尺带容纳在壳体内,尺带的尾端连接盘簧并卷绕在鼓轮上,尺带的零刻度线端和壳体分别固定在主尺1和第一副尺2上;Angle measuring device 4 comprises a chi tape with an angle mark, a housing and a drum; the drum is arranged in the housing and is connected with the housing by a coil spring; the chi tape is accommodated in the housing, and the tail end of the chi tape is connected to the coil spring and Wound on the drum, the zero scale end of the scale tape and the housing are respectively fixed on the main scale 1 and the first auxiliary scale 2;
主尺1和第一副尺2上设有直形滑槽5,直形滑槽5分别与主尺1和第一副尺2长度方向平行,第二副尺3的两端分别滑动连接于主尺1和第一副尺2上的直形滑槽4上。The main ruler 1 and the first auxiliary ruler 2 are provided with a straight chute 5, the straight chute 5 is respectively parallel to the length direction of the main ruler 1 and the first auxiliary ruler 2, and the two ends of the second auxiliary ruler 3 are slidably connected to the On the straight chute 4 on the main ruler 1 and the first auxiliary ruler 2.
可见,本实施例提出的多功能教具,由于主尺、第一副尺和第二副尺为带有刻度线的直尺,从而具备直尺的功能,同时由于带有角度标识的尺带的零刻度线端和壳体分别固定在主尺和第一副尺上,所以可以通过主尺、第一副尺和尺带进行角度的测量,从而具备量角器的功能,另外主尺、第一副尺和第二副尺可以组成三角形,从而具备三角尺的功能。It can be seen that the multifunctional teaching aid proposed in this embodiment has the function of a straightedge because the main ruler, the first auxiliary ruler and the second auxiliary ruler are rulers with scale marks, and at the same time because the ruler tape with the angle mark The end of the zero scale line and the housing are respectively fixed on the main ruler and the first auxiliary ruler, so the angle can be measured through the main ruler, the first auxiliary ruler and the ruler tape, so that it has the function of a protractor. In addition, the main ruler, the first auxiliary ruler The ruler and the second auxiliary ruler can form a triangle, thereby possessing the function of a triangular ruler.
图2本发明又一实施例中量角装置4的剖面示意图,包括带有角度标识的尺带401、壳体402和设置在壳体402内且与壳体通过盘簧403连接的鼓轮404;尺带401容纳在壳体402内,尺带401的尾端连接盘簧403并卷绕在鼓轮404上。Fig. 2 is a schematic cross-sectional view of the angle measuring device 4 in another embodiment of the present invention, including a ruler tape 401 with an angle mark, a housing 402, and a drum 404 arranged in the housing 402 and connected to the housing through a coil spring 403 The ruler tape 401 is housed in the housing 402, and the tail end of the ruler tape 401 is connected to the coil spring 403 and wound on the drum 404.
在本实施例中,尺带的零刻度线端和壳体分别固定在主尺和第一副尺上,由于固定的位置是确定的,可以根据固定在主尺和第一副尺的位置距离零刻度线的距离和尺带被拉开的长度来确定主尺和第一副尺的角度。举例来说,当尺带的零刻度线端和壳体分别固定在主尺和第一副尺距离零刻度线3厘米的位置时,当尺带被拉开的长度为3厘米处时,即主尺和第一副尺为角度为60度处。同理,可以确定尺带的角度标识。In this embodiment, the zero scale end of the tape and the housing are respectively fixed on the main scale and the first auxiliary scale. Since the fixed position is determined, it can be fixed according to the positional distance between the main scale and the first auxiliary scale. The distance from the zero scale line and the stretched length of the tape determine the angle between the main ruler and the first auxiliary ruler. For example, when the end of the zero scale line of the scale tape and the housing are respectively fixed at a position 3 cm away from the zero scale line of the main scale and the first auxiliary scale, when the length of the scale tape is pulled apart to 3 cm, that is The main ruler and the first auxiliary ruler are at an angle of 60 degrees. In the same way, the angle mark of the ruler tape can be determined.
在本发明的一个优选实施例中,第二副尺的长度小于主尺和第一副尺的长度。In a preferred embodiment of the present invention, the length of the second sub-scale is smaller than the lengths of the main scale and the first sub-scale.
在本实施例中,由于第二副尺的长度小于主尺和第一副尺的长度,所以主尺和第一副尺可以完全闭合,第二副尺的一端靠近主尺或第一副尺的零刻度线端,第二副尺的另一端靠近主尺或第一副尺的活动端。当主尺和第一副尺完全闭合时,整个数学用多功能教具闭合为一根直尺,方便使用和携带。In this embodiment, since the length of the second sub-scale is smaller than the length of the main scale and the first sub-scale, the main scale and the first sub-scale can be completely closed, and one end of the second sub-scale is close to the main scale or the first sub-scale The other end of the second sub-scale is close to the active end of the main scale or the first sub-scale. When the main ruler and the first auxiliary ruler are fully closed, the whole multifunctional teaching aid for mathematics is closed into a ruler, which is convenient to use and carry.
在本发明的一个优选实施例中,主尺和第一副尺的长度相等,主尺活动端和第一副尺活动端分别安装有圆规支点和粉笔套。In a preferred embodiment of the present invention, the lengths of the main ruler and the first auxiliary ruler are equal, and the movable ends of the main ruler and the first auxiliary ruler are respectively equipped with a compass fulcrum and a chalk cover.
详细的,主尺的零刻度线处铰连接第一副尺的零刻度线处,因此主尺和第一副尺可以相对零刻度线处旋转。通过在主尺活动端和第一副尺活动端分别安装有圆规支点和粉笔套,可以将多功能教具当做圆规使用。In detail, the zero scale line of the main scale is hinged to the zero scale line of the first auxiliary scale, so the main scale and the first auxiliary scale can rotate relative to the zero scale line. The multi-functional teaching aid can be used as a compass by installing a compass fulcrum and a chalk cover respectively at the movable end of the main ruler and the movable end of the first auxiliary ruler.
综上所述,本发明实施例至少可以实现如下效果:In summary, the embodiments of the present invention can at least achieve the following effects:
在本发明实施例中,由于主尺、第一副尺和第二副尺为带有刻度线的直尺,从而具备直尺的功能,同时由于带有角度标识的尺带的零刻度线端和壳体分别固定在主尺和第一副尺上,所以可以通过主尺、第一副尺和尺带进行角度的测量,从而具备量角器的功能,另外主尺、第一副尺和第二副尺可以组成三角形,从而具备三角尺的功能。In the embodiment of the present invention, since the main ruler, the first auxiliary ruler and the second auxiliary ruler are rulers with scale lines, they have the function of a straightedge, and at the same time, due to the zero scale end of the scale tape with the angle mark and the housing are respectively fixed on the main ruler and the first auxiliary ruler, so the angle can be measured through the main ruler, the first auxiliary ruler and the tape, thus having the function of a protractor. In addition, the main ruler, the first auxiliary ruler and the second The auxiliary ruler can form a triangle, thereby possessing the function of a triangular ruler.
在本发明实施例中,由于第二副尺的长度小于主尺和第一副尺的长度,从而主尺和第一副尺可以完全闭合,第二副尺的一端靠近主尺或第一副尺的零刻度线端,第二副尺的另一端靠近主尺或第一副尺的活动端;当主尺和第一副尺完全闭合时,整个多功能教具闭合为一根直尺,方便使用和携带。In the embodiment of the present invention, since the length of the second auxiliary ruler is smaller than the length of the main ruler and the first auxiliary ruler, the main ruler and the first auxiliary ruler can be completely closed, and one end of the second auxiliary ruler is close to the main ruler or the first auxiliary ruler. The zero scale end of the ruler, the other end of the second auxiliary ruler is close to the active end of the main ruler or the first auxiliary ruler; when the main ruler and the first auxiliary ruler are completely closed, the entire multifunctional teaching aid is closed into a ruler, which is convenient to use and carry.
在本发明实施例中,由于主尺和第一副尺的长度相等,主尺活动端和第一副尺活动端分别安装有圆规支点和粉笔套,从而可以将多功能教具当做圆规使用。In the embodiment of the present invention, since the lengths of the main ruler and the first auxiliary ruler are equal, the movable ends of the main ruler and the first auxiliary ruler are respectively equipped with a compass fulcrum and a chalk cover, so that the multifunctional teaching aid can be used as a compass.
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention.
