The present invention may be further configured in a preferred embodiment as: the locating part is rod-shaped, the opening of the closed-loop chute towards one side outside the ruler body is smaller than the length of the locating part and larger than the diameter of the locating part.

The present invention may be further configured in a preferred embodiment as: the connecting piece is including being fixed in the connecting rod between the locating part, the length of connecting piece is greater than the distance between two closed loop spout bottoms.

The present invention may be further configured in a preferred embodiment as: the length direction of the ruler body is provided with a plurality of elongated parts, and the elongated parts are arranged on one side of the ruler body in the width direction and positioned at two ends of the ruler body in the length direction in an extending manner; when the two ruler bodies are positioned on the same plane, the lengthening parts are in butt fit with each other.

The present invention may be further configured in a preferred embodiment as: convex ridges are arranged in the middle of the connecting rod at intervals in the circumferential direction around the axis of the connecting rod.

The present invention may be further configured in a preferred embodiment as: the closed-loop sliding groove comprises a pair of straight sliding grooves and a pair of semicircular sliding grooves, and the semicircular sliding grooves are connected to two ends of the straight sliding grooves respectively.

To sum up, the utility model discloses a following at least one useful technological effect:

when drawing straight lines, the two ends of the sliding ruler body are abutted, when the length is insufficient, one ruler body is pressed to be immobile, the other ruler body is slid, the length for guiding and marking is prolonged, and the other ruler body is immobile, so that the straight line straightness is ensured.

Drawings

FIG. 1 is a schematic view of the connection structure of two ruler bodies in the same plane;

fig. 2 is a schematic diagram for embodying a closed-loop chute structure.

In the figure, 1, a ruler body; 11. a lengthening part; 2. a closed loop chute; 21. a straight chute; 22. a semicircular chute; 3. a limiting member; 4. A connecting member; 41. and (4) convex edges.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the multifunctional ruler for drawing comprises a pair of ruler bodies 1, wherein a closed-loop chute 2 is formed in the periphery of each ruler body 1, the closed-loop chute 2 extends along the length direction and the thickness direction of each ruler body 1, and a connecting component is arranged between the closed-loop chutes 2 of the two ruler bodies 1;

when the ruler body 1 is used, the two ruler bodies 1 are always parallel, and when the ruler body 1 needs to be stored in a pen box, the ruler body 1 is slid, so that the ruler body 1 is overlapped and attached, and the ruler body 1 can be conveniently stored in the pen box; when drawing a straight line, the two ends of the sliding ruler body 1 are abutted, when the length is insufficient, one ruler body 1 is pressed and fixed, the other ruler body 1 is slid, the length for guiding the drawing line is prolonged, and the other ruler body 1 is fixed, so that the straightness of the straight line is ensured.

The connecting component comprises a pair of limiting parts 3 and a connecting part 4, the limiting parts 3 and the connecting part 4 are of rod-shaped structures, the two limiting parts 3 are respectively installed in different closed-loop chutes 2, the connecting part 4 is fixedly connected between the limiting parts 3, and an opening of the closed-loop chute 2 towards the outer side of the ruler body 1 is smaller than the length of the limiting parts 3 and larger than the diameter of the limiting parts 3, so that the two ruler bodies 1 are always connected, and the condition that a single ruler body 1 is lost is avoided.

Wherein the length of connecting piece 4 is greater than the distance between two annular spout bottoms to it has protruding stupefied 41 to extend around its axis circumference interval in the middle part of connecting rod, so when will assemble chi body 1 with continuous subassembly, at first put into closed loop spout 2 with locating part 3 is on a parallel with chi body 1 length direction, then rotates through the middle part of control connecting piece 4, drives the rotation of locating part 3, makes locating part 3 perpendicular to the length direction of chi body 1, guarantees the stability of connecting between the chi body 1.

Meanwhile, the two ends of one side of the ruler body 1 in the width direction and in the length direction extend to form lengthened parts, and the lengthened parts extend along the length direction of the ruler body 1; when the two ruler bodies 1 are positioned on the same plane, the lengthening parts are in butt fit, so that a gap is prevented from being formed between the ruler bodies 1, and the ruler bodies are convenient to linearly and sequentially form.

Wherein closed loop spout 2 includes a pair of straight chute 21 and a pair of semicircle arc groove, and semicircle spout 22 is connected respectively in the both ends of straight chute 21, and the gag lever post is more smooth and easy when the gag lever post moves about in semicircle spout 22 to the removal of the chi body 1 of being convenient for.

The implementation principle of the embodiment is as follows:

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
