Abstract
The utility model discloses a take magnetic teaching ruler, including the chi of the rectangle body with measure the location body, measure the location body and including measuring the body and the location body, fix a position the internal magnetic suction block that is equipped with, measure the body and for transparent plastic material, measure the internal colored liquid that is equipped with, be equipped with annular angle scale on measuring the up end of the body, measure the body and personally experience sth. Part of the body through connecting rod fixed connection with the location, the bottom surface of the chi body and the bottom surface of the location body are on same horizontal plane, and the front end of the chi body is equipped with curved breach, the one end of breach is equipped with the rotatory piece of circular shape, and the through -hole has been seted up at the center of rotation piece, and rotatory piece cover can rotate around the connecting rod on locating the connecting rod. The utility model discloses simple structure, convenient and practical can adsorb the one end of the chi body on the blackboard, and take and hold very easily, the required inclination's that can draw up fast straight line, the operation is very succinct quick.
Description
Technical field
This utility model relates to educational aid field, specifically, is related specifically to a kind of magnetic teaching ruler。
Background technology
Class hour is said in teacher's teaching of use chi setting-out on blackboard, and pinning chi body with hands could use, and this traditional occupation mode can allow teacher give lectures and feel tired。Meanwhile, when teacher draws horizontal linear or the angled straight lines with angle on blackboard, it is generally only and judges by subjective experience。Some on market teaching rulers with angle regulating function, complicated structure, very inconvenient by holding when teacher draws on blackboard。
Utility model content
The purpose of this utility model is in that for deficiency of the prior art, it is provided that a kind of magnetic teaching ruler, to solve the problems referred to above。
This utility model is solved the technical problem that to realize by the following technical solutions:
A kind of magnetic teaching ruler, chi body including rectangle, also include measurement and positioning body, described measurement and positioning body includes cylindrical and boring structure measurement body and positioning body, being provided with magnetic suction block in positioning body, measurement body is transparent plastics material, measures and internal is provided with colored liquid, the upper surface measuring body is provided with annular angle index, measures body and positioning body and connects by connecting rod is fixing；The bottom surface of chi body and the bottom surface of positioning body are in same level, and the front end of chi body is provided with the breach of arc, and the structure of breach and the outer wall of positioning body adapt；One end of breach is provided with the spill spin block of circle, spill spin block and chi body by integral forming, and the center of spill spin block offers through hole, and spill spin block is sheathed in connecting rod and can rotate around connecting rod。
Compared with prior art, the beneficial effects of the utility model are as follows:
This utility model simple in construction, convenient and practical。In the process used, by positioning body, one end of chi body is adsorbed on blackboard, as long as the other end of user flicking chi body can easily be rule；Chi body can rotate around connecting rod, by measuring the scale on body, can quickly draw the straight line at required angle of inclination, and operation is very succinct quickly。
Accompanying drawing explanation
Fig. 1 is the structural representation of magnetic teaching ruler described in the utility model。
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with detailed description of the invention, this utility model is expanded on further。
Referring to Fig. 1, the magnetic teaching ruler of one described in the utility model, including chi body 10 and the measurement and positioning body 20 of rectangle。Measurement and positioning body 20 includes cylindrical and boring structure measurement body 21 and positioning body 22。Magnetic suction block it is provided with in positioning body 22。Measuring body 21 is transparent plastics material, measures and is provided with colored liquid in body 21, and the upper surface measuring body 21 is provided with annular angle index。Measure body 21 and positioning body 22 to connect by connecting rod 3 is fixing。The bottom surface of the bottom surface of chi body 10 and positioning body 22 is in same level。The front end of chi body 10 is provided with the outer wall of the breach 11 of arc, the structure of breach 11 and positioning body 22 and adapts。One end of breach 11 is provided with the spill spin block 4 of circle, and spill spin block 4 is one-body molded with chi body 10。The center of spill spin block 4 offers through hole, and spill spin block 4 is sheathed in connecting rod 3 and can rotate around connecting rod 3。
One end of chi body 10, in the process used, is adsorbed on blackboard, as long as the other end of user flicking chi body 10 can easily be rule by this utility model by positioning body 22。
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described。Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model。This utility model claims scope and is defined by appending claims and equivalent thereof。
