Description

Folding simple ruler

Technical Field

The utility model relates to a teaching aid technical field specifically is a foldable simple and easy ruler.

Background

When teachers in middle and primary schools teach in classroom, a ruler and compasses are often needed for drawing. The common ruler does not have the using function of compasses, and the compasses do not have the function of the ruler. Teachers need to carry various teaching aids such as rulers and compasses at the same time, so that the carrying is inconvenient and the use is inconvenient.

Therefore, in view of the above situation, there is a strong need to develop a foldable simple ruler.

In order to achieve the above object, the utility model provides a following technical scheme:

a folding simple ruler comprises a first ruler and a second ruler; the first ruler and the second ruler are hinged through a hinge shaft; a first slide way is arranged on the first ruler; a second slide way is arranged on the second ruler; an adjusting mechanism is arranged between the first ruler and the second ruler.

As a further aspect of the present invention: the adjusting mechanism comprises a clamp; one side of the hoop is provided with a chute corresponding to the first slideway; the other side of the hoop is provided with a groove corresponding to the second slide way; one side of the hoop is clamped with the first slideway through a chute; the other side of the clamp is clamped with the second slide rail through the groove.

As a further aspect of the present invention: and the clamp is provided with positioning holes corresponding to the second slide way and the groove.

As a further aspect of the present invention: two positioning holes are formed; and butterfly screws are rotatably arranged on the positioning holes.

As a further aspect of the present invention: a fixed foot is arranged at one end of the first ruler, which is far away from the articulated shaft; and a chalk sleeve is arranged at one end, far away from the hinged shaft, of the second ruler.

Compared with the prior art, the beneficial effects of the utility model are that: the device is prevented from swinging left and right through the arrangement of the chute; through the arrangement of the first slide way, the second slide way, the chute and the groove, the hoop can slide up and down, the angle between the first ruler and the second ruler is adjusted, and the radius of a drawn circle is further adjusted; the butterfly screw is arranged in the positioning hole; when a circle needs to be drawn, the butterfly screw is unscrewed, the hoop is pushed to slide up and down, when the butterfly screw slides to a certain position and reaches the radius of the drawn circle, the butterfly screw is screwed down, and the hoop is fixed, so that the circle can be drawn; through the arrangement of the two fixed hole holes, the fixing effect is better; the chalk holder is more convenient to use through the arrangement of the fixing feet and the chalk sleeve. To sum up, the utility model discloses convenient to use can the ruler rule dual-purpose.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Reference will now be made in detail to embodiments of the present patent, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present patent and are not to be construed as limiting the present patent.

Example 1

Referring to fig. 1 to 4, in an embodiment of the present invention, a foldable simple ruler includes a first ruler 1 and a second ruler 2; the first ruler 1 and the second ruler 2 are hinged through a hinge shaft 6; the first ruler 1 is provided with a first slideway 4; a second slide way 5 is arranged on the second ruler 2; an adjusting mechanism is arranged between the first ruler 1 and the second ruler 2.

Further, the adjusting mechanism comprises a clamp 3; one side of the hoop 3 is provided with a chute 9 corresponding to the first slideway 4; the other side of the hoop 3 is provided with a groove 11 corresponding to the second slide way 5; one side of the hoop 3 is clamped with the first slide way 4 through a chute 9; the other side of the hoop 3 is clamped with the second slide way 5 through a groove 11; the device is prevented from swinging left and right through the arrangement of the chute 9; through the setting of first slide 4, second slide 5, chute 9 and recess 11, clamp 3 can slide from top to bottom, adjusts the angle between first chi 1 and the second chi 2, and then adjusts the radius of the circle of drawing.

Furthermore, a positioning hole 10 is formed in the hoop 3 corresponding to the second slide way 5 and the groove 11.

Further, two positioning holes 10 are arranged; butterfly screws are rotatably arranged on the positioning holes 10; mounting a thumb screw into the locating hole 10; when a circle needs to be drawn, the butterfly screw is unscrewed, the hoop 3 is pushed to slide up and down, and when the butterfly screw slides to a certain position and reaches the radius of the drawn circle, the butterfly screw is screwed down, and the hoop 3 is fixed, so that the circle can be drawn; through the setting of two fixed hole holes 10, the fixed effect is better.
