It can be used to draw straight lines, and can also express quantities visually and perform simple addition and subtraction operations. It is fun to teach and is conducive to the development of children's intelligence.

本实用新型所采用的技术方案是：该珠算尺包括带有刻度的本体，其技术要点是：所述本体上设置有长条形滑槽和组装在滑槽内的沿滑槽移动的算珠，底部带卡盘的算珠横截面呈“工”字形。 The technical scheme adopted by the utility model is: the abacus ruler includes a body with scales, and its technical points are: the body is provided with a long strip-shaped chute and an abacus moving along the chute assembled in the chute , the cross-section of the bead with the chuck at the bottom is in the shape of "I".

所述本体的滑槽端部设置扩大孔，算珠的底部卡盘从滑槽端部扩大孔装入，并以封堵固定封闭扩大孔。 The end of the chute of the body is provided with an enlarged hole, and the bottom chuck of the beads is loaded from the enlarged hole at the end of the chute, and the enlarged hole is fixed and closed with a plug.

所述算珠露出滑槽的表面形状为圆形体、椭圆形体、多边形体或卡通图形体。 The surface shape of the chute where the beads are exposed is circular, elliptical, polygonal or cartoon-shaped.

本实用新型具有的优点及积极效果是：由于本实用新型采用带算珠的文具用尺，所以其可以实现一尺多用，既能与普通直尺一样用于画直线，又能同珠算一样进行形象表达数量及进行简单的加减运算。因其是在现有带刻度的直尺上设置滑槽和在滑槽内装算珠，故结构设计合理，结构简单，利用装在滑槽内的算珠不仅可以使儿童，特别是学龄前儿童，能够辅助其用算珠形象地表达数量，也可以用于低年级小学生辅助其进行简单的加减运算，而且使用方便、安全。这种寓乐于教的文具，非常有利于儿童智力的开发。 The advantages and positive effects of the utility model are: since the utility model adopts a stationery ruler with beads, it can be used for multiple purposes. It can be used for drawing straight lines like an ordinary ruler, and it can also be used for abacus calculation. Visually express quantities and perform simple addition and subtraction operations. Because the chute is set on the existing ruler with scale and the beads are installed in the chute, the structural design is reasonable and the structure is simple. The use of the beads installed in the chute can not only make children, especially preschool children , can assist them to express quantity visually with beads, and can also be used for elementary school students in low grades to assist them in simple addition and subtraction operations, and is convenient and safe to use. This kind of stationery that entertains and teaches is very beneficial to the development of children's intelligence.

具体实施方式 Detailed ways

根据图1～3详细说明本实用新型的具体结构。该珠算尺包括带有刻度（图中未示出）的本体1、滑槽3和算珠2。其中本体1的规格形状、尺寸和刻度，应根据实际使用需要和设计要求，可以制成两种结构形式。 The specific structure of the utility model is explained in detail according to Fig. 1-3. The abacus ruler includes a body 1 with a scale (not shown in the figure), a chute 3 and a bead 2 . Wherein the specification shape, size and scale of the body 1 should be made into two structural forms according to actual use needs and design requirements.

第一种结构形式如图1 所示。本体1上设置有长条形滑槽3和组装在滑槽3内的可以沿滑槽3的长度方向移动的算珠2，算珠2的规格形状可按设计要求选择。底部带卡盘的算珠2横截面呈“工”字形，并利用底部的卡盘将算珠2卡在长条形滑槽3内。算珠2的露出滑槽3的表面形状，可以设计成为圆形体、椭圆形体、多边形体或儿童喜欢的卡通图形体。 The first structural form is shown in Figure 1. The body 1 is provided with an elongated chute 3 and a counting bead 2 assembled in the chute 3 that can move along the length direction of the chute 3, and the specification and shape of the counting bead 2 can be selected according to design requirements. The cross-section of the bead 2 with the chuck at the bottom is "I" shape, and the bead 2 is stuck in the elongated chute 3 by the chuck at the bottom. The surface shape of the exposed chute 3 of the beads 2 can be designed as a circular body, an oval body, a polygonal body or a cartoon figure body that children like.

第二种结构形式如图3 所示。为了组装方便，可以将滑槽3的端部设置扩大孔，组装时，也可以将算珠2的卡盘从滑槽3端部的扩大孔内装入，并以封堵4固定封闭扩大孔。其中算珠2的卡盘的外形尺寸应略小于扩大孔的尺寸，并大于滑槽3的槽宽，以便使卡盘放进扩大孔后，既能在滑槽3内自由移动，又不能使卡盘从滑槽3中脱落，确保使用安全。 The second structural form is shown in Figure 3. For the convenience of assembling, the end of chute 3 can be provided with enlarged hole, during assembling, also can the chuck of bead 2 be packed in the enlarged hole of chute 3 ends, and with plugging 4, fix and close the enlarged hole. Wherein the overall dimension of the chuck of bead 2 should be slightly smaller than the size of the enlarged hole, and greater than the groove width of chute 3, so that after the chuck is put into the enlarged hole, it can move freely in the chute 3 without causing the The chuck comes off from the chute 3 to ensure safe use.
