Abstract
The utility model relates to a multifunctional teaching aid ruler, which belongs to a teaching aid. The multifunctional teaching aid ruler comprises a square and a handle, wherein the square comprises a transverse ruler and a longitudinal ruler which is perpendicular to the transverse ruler, the left end of the longitudinal ruler is provided with a protruded edge, and the handle is arranged on the protruded edge; and a sliding chute is longitudinally arranged on the middle part of the longitudinal ruler, a groove is arranged corresponding to the back surface of the sliding chute, a regulating screw is arranged in the sliding chute, a movable transverse ruler is driven by the regulating screw to be arranged in the sliding chute in a sliding mode, and the movable transverse ruler and the transverse ruler of the square are arranged in an upper and down parallel mode. When a teacher draws a picture with the multifunctional teaching aid ruler disclosed by the utility model, parallel lines can be drawn directly through the two transverse rulers, and if a standard distance between the two parallel lines is specified, only the movable transverse ruler needs to be slid up and down through the regulating screw to measure the standard distance.
Description
Technical field
The utility model relates to a kind of stationery, specifically a kind of Multifunctional teaching aid chi.
Background technology
Teacher often can draw parallel lines or the figures such as rectangle, parallelogram at blackboard in that when several explain for classmates, needs the size at repeated measurement line segment two ends when drawing parallel lines, and is parallel to guarantee, pretty troublesome, also loses time.
The utility model content
The purpose of this utility model is to provide a kind of Multifunctional teaching aid chi, and this teaching ruler can make things convenient for teacher at the figure that draws parallel lines and be comprised of the equality line.
The technical scheme in the invention for solving the technical problem is: a kind of Multifunctional teaching aid chi, its structure comprises square and handle, described square comprises horizontal chi and the longitudinal ruler vertical with horizontal chi, establishes one at the left end of longitudinal ruler and protrudes the edge, protrudes along upper mounting knob; Described longitudinal ruler middle part is vertically arranged with a chute, a recessed pockets is established at the back side of corresponding chute, establish a set screw in the chute, described set screw drives movable transverse and is slidingly arranged in the chute to chi, and described movable transverse is arranged in parallel up and down to the horizontal chi of chi and square.
The beneficial effects of the utility model are: when teacher uses this Multifunctional teaching aid chi to draw at blackboard, can directly draw parallel lines by two horizontal chis, if two the specified standard distance is arranged between the parallel lines, only need by set screw movable transverse to be slided up and down to chi, measure gauged distance and get final product, the figure that this chi can make things convenient for teacher to draw straight line, right angle, parallel lines and be comprised of parallel lines at blackboard.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 square, 2 protrude edges, 3 handles, 4 chutes, 5 recessed pockets, 6 movable transverse are to chi, 7 set screw.
The specific embodiment
As shown in Figure 1.A kind of Multifunctional teaching aid chi, comprise square 1 and handle 3, described square 1 comprises horizontal chi and the longitudinal ruler vertical with horizontal chi, establishing one at the left end of longitudinal ruler protrudes along 2, protrusion is along mounting knob on 23, and described longitudinal ruler middle part is vertically arranged with a chute 4, and a recessed pockets 5 is established at the back side of corresponding chute 4, recessed pockets 5 is used for holding the afterbody of set screw 7, avoids causing the out-of-flatness of the teaching ruler back side; Establish a set screw 7 in the chute 4, described set screw 7 drives movable transverse and is slidingly arranged in the chute 4 to chi 6, determine size according to the movable transverse of can sliding of the distance between two parallel lines to chi, described movable transverse is arranged in parallel up and down to the horizontal chi of chi and square.Movable transverse is supported on the right side of protruding along 2 to the left end of chi 6, to guarantee that movable transverse remains vertical to chi 6 and longitudinal ruler.
When teacher uses this Multifunctional teaching aid chi to draw at blackboard, available left hand is held handle 3, the right hand draws parallel lines according to two horizontal chis, if two the specified standard distance is arranged between the parallel lines, can draw article one line according to horizontal chi first, set screw makes movable transverse to chi 6 to gauged distance and tightens set screw 7 again, can draw the second line to chi 6, the figure that this chi can make things convenient for teacher to draw straight line, right angle, parallel lines and be comprised of parallel lines at blackboard according to movable transverse.
