The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail below with reference to the drawings and embodiments.

A multifunctional triangular ruler is shown in figures 1 to 5 and comprises a main body 1, an auxiliary body 2 and an adjusting body 3, wherein a triangular area 4 is formed by the three parts in a surrounding manner; a first sliding groove 5 is formed in the middle of the main body (along the length direction of the main body), a first adjusting piece 6 is arranged in the first sliding groove in a sliding mode, a second sliding groove 7 is formed in the middle of the auxiliary body (along the length direction of the auxiliary body), and a second adjusting piece 8 is arranged in the second sliding groove in a sliding mode; it should be noted that the scale marks on the main body, the auxiliary body and the adjustment body are all located at one side close to the triangular area, which is very convenient for operations such as triangle drawing, measurement and dotting marks.

After the included angle between the main body and the auxiliary body is adjusted and the positions of two ends of the adjusting body relative to the hinge points of the main body and the auxiliary body are adjusted, the adjusting body is fixed with the main body and the auxiliary body respectively through the locking piece, the inner end surfaces of the main body and the auxiliary body are positioned on the same plane, the adjusting body is arranged on one side of the outer end surfaces of the main body and the auxiliary body, the adjusting body is very convenient to adjust and move integrally, and the main body and the auxiliary body can form stable support together due to the structural design.

The starting end 9 of the auxiliary body is hinged with the starting end 10 of the main body, and the adjusting groove 11 in the middle of the adjusting body is simultaneously in sliding fit with the first adjusting piece and the second adjusting piece. For example, the adjusting members may be engaged with the corresponding sliding grooves in a T-shaped configuration to ensure that the adjusting member is not separated from the main body and the auxiliary body.

The starting end of the main body or the starting end of the auxiliary body is provided with an angle mark 12. For example, a dial is arranged for indicating the angle of the included angle formed between the main body and the auxiliary body, and the numerical value of the included angle between the main body and the auxiliary body can be conveniently determined or read.

In an optional embodiment, the inner end surfaces of the main body and the auxiliary body are respectively provided with a supporting pad, and the end surfaces of the supporting pads are positioned on the same plane, so that the triangular ruler is stably attached to the blackboard. In order to reduce the load burden during use, in another optional embodiment, the inner end surfaces of the main body and the auxiliary body are respectively provided with a magnetic cushion block, the end surfaces of the magnetic cushion blocks are on the same plane, when the magnetic blackboard is used, the main body and the auxiliary body can be simultaneously adsorbed on the magnetic blackboard, and it needs to be noted that the magnetic adsorption acting force can overcome the weight of the triangular ruler, but cannot hinder the adjustment operation of the triangular ruler.

In an alternative embodiment, the first adjusting member includes a first sliding block portion 13 slidably engaged with the first sliding groove, and a first connecting portion 14 slidably engaged with the adjusting groove. The second adjusting piece comprises a second sliding block part in sliding fit with the second sliding groove and a second connecting part in sliding fit with the adjusting groove.

For example, the external thread structure is arranged at one end of each connecting part extending out of the corresponding sliding groove, the locking piece can be a locking nut 15 arranged on the corresponding external thread structure, after the auxiliary body and the adjusting body are adjusted to the required positions, the locking nut can be screwed, the adjusting body is tightly pressed by the locking nut, and then the adjusting body is tightly attached to the auxiliary body (or the main body), and the triangular ruler is only used for measuring or drawing figures when in use, so that the friction force between the adjusting body and the auxiliary body (or the main body) is enough to ensure the structural stability. FIG. 4 is a schematic view of a portion of a first adjuster with a lock nut according to the present invention;

in another alternative embodiment, the end surfaces of the connecting portions are all submerged into the corresponding sliding grooves, the end surfaces of the connecting portions are provided with internal thread structures, the locking members adopt locking screws 16 screwed with the internal thread structures, and after the auxiliary body and the adjusting body are adjusted to the required positions, the adjusting body can be tightly attached to the auxiliary body (or the main body) by tightening the locking screws and pressing the adjusting body with the screws. As shown in FIG. 5, a schematic view of the portion of the first adjustment member when a locking screw is used is created for the present invention.

Of course, the locking member may be replaced by other structures or other parts, as long as the position of the adjustment body can be fixed when needed, and the design is also feasible by those skilled in the art by using the conventional technology, and the details are not described herein.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, and any modifications, equivalents, improvements and the like that are made within the spirit and principle of the present invention should be included in the scope of the present invention.
