Abstract
The utility model discloses an angular measurement plate which comprises a straight plate and a semicircular arc plate, wherein the semicircular arc plate is positioned above the straight plate and adopts an integral structure with the straight plate, one end of the semicircular arc plate is connected with one end of the straight plate, and the other end of the semicircular arc plate is connected with the other end of the straight plate; and the angular measurement plate is characterized in that the semicircular arc plate is annular, wherein scales are arranged on the circular arc on the outer edge of the semicircular arc plate, an arc-shaped groove is formed along the arc-shaped edge inside the semicircular arc plate, one end of a rotating rod is rotatably connected with the straight plate, a pen sleeve is fixedly arranged at the other end of the rotating rod, positioned outside the semicircular arc plate and is in contact with the edge of the semicircular arc plate, and a pen refill is installed in the pen sleeve. The angular measurement plate not only can achieve the purpose of measuring and drawing of angle, but also can be used for drawing a circle, a circular arc and a straight line, the using function of the angular measurement plate is enriched, and the angular measurement plate is convenient for pupils and teachers to use.
Description
Technical field
The utility model relates to a kind of schooling apparatus, especially a kind of angular surveying plate.
Background technology
In pupil's mathematical studying, the angle with certain angle of learning how to take measurement of an angle and draw as requested is the knowledge that must grasp.At present, general use amount hornwork carries out the measurement and the drafting of angle.But the protractor of existing structure can only carry out the measurement and the drafting of angle, can't realize other function, and purposes is very single.
Summary of the invention
The purpose of this utility model is to provide a kind of angular surveying plate, not only can realize the measurement and the drafting of angle, can also utilize it to draw circle, draws circular arc, draw straight line etc., has enriched the function of use of angular surveying plate, is convenient to pupil and teacher and uses.
In order to reach above purpose, the technical scheme that the utility model adopted is: this angular surveying plate, comprise straight plate and semi arch plate, the semi arch plate is positioned at the top of straight plate, and the semi arch plate is integral structure with straight plate, wherein an end of semi arch plate is connected with an end of straight plate, the other end is connected with the other end of straight plate, it is characterized in that: described semi arch plate in the form of a ring, the outer circular arc of semi arch plate is provided with scale value, arc edge, inside along the semi arch plate is provided with deep-slotted chip breaker, one end of swingle is rotatably connected by the middle part of rotating shaft with straight plate, and the other end fixedly installs the pen cap, and the pen cap is positioned at the outside of semi arch plate, and, pen core is housed in the pen cap with the EDGE CONTACT of semi arch plate.
The utility model is also implemented by following measure: with on the corresponding swingle in described deep-slotted chip breaker position guide finger is set, guide finger slides in deep-slotted chip breaker, the cross sectional shape of guide finger is T-shaped.
The beneficial effects of the utility model are: compare with at present used protractor, owing to increased swingle, not only can realize the measurement and the drafting of angle, can also be used to draw circular arc, semicircle, circle or straight line, greatly enriched the function of this angular surveying plate, be convenient to student and teacher and use.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 to Fig. 4 is an angular surveying plate described in the utility model.This angular surveying plate comprises straight plate 3 and semi arch plate 1, and semi arch plate 1 is positioned at the top of straight plate 3, and semi arch plate 1 is integral structure with straight plate 3, and wherein an end of semi arch plate 1 is connected with an end of straight plate 3, and the other end is connected with the other end of plate 3 directly.Described semi arch plate 1 in the form of a ring, therefore the outer circular arc of semi arch plate 1 is provided with scale value, utilizes semi arch plate 1 can realize the measurement and the drafting of angle, the arc edge, inside along semi arch plate 1 is provided with deep-slotted chip breaker 2 simultaneously.This angular surveying plate also comprises swingle 4, and wherein an end of swingle 4 is rotatably connected with straight plate 3 by rotating shaft, and the other end fixedly installs the pen cap 5, the pen cap 5 is positioned at the outside of semi arch plate 1, and with the EDGE CONTACT of semi arch plate 1, pen core 7 is housed in the pen cap 5, pen core 7 is towards drawing board.As shown in Figure 3, when swingle 4 rotations, can drive pen core 7 rotations in the pen cap 5 and the pen cap 5, thereby realize the drafting of circular arc.When the end of swingle 4 along deep-slotted chip breaker 2 from groove moved to its other end, a complete semicircle can draw.
In addition, be provided with guide finger 6 with the corresponding swingle 7 in deep-slotted chip breaker 2 positions, guide finger 6 can slide in deep-slotted chip breaker 2, the cross sectional shape of guide finger 6 is T-shaped, by the bigger end of guide finger 6 diameters, swingle 7 is slided along deep-slotted chip breaker 2 all the time, and can not leave deep-slotted chip breaker 2.Therefore guide finger 6 has played the effect of location and guiding.In addition, with the corresponding swingle 7 in deep-slotted chip breaker 2 positions on also the pen cap can be set, pen core is set in the pen cap, the pen cap can slide along deep-slotted chip breaker 2, has realized drawing at the different radii place circular arc.
