[0022] Example 1:

[0023] The embodiment gives a kind of combination ruler for children, as shown in Figures 1-3 Figure 1, the ruler 1 is combined by upper ruler part 10 and lower ruler part 11, the ruler 1 has first morphology and second morphology under the limitation of external constraint, the first morphology is that lower ruler part 11 is folded in the inside of upper ruler part 10 folding, the second morphology is that lower ruler part 11 is turned to the unfolded state with upper ruler part 10 horizontal;The ruler 1 can be controlled to unfold to the second morphology from the first morphology;

[0024] A plurality of half figure grooves 12 are formed on the upper ruler part 10 and the lower ruler part 11, when the ruler 1 is controlled to unfold to the second morphology from the first morphology, the half figure grooves 12 on the upper ruler part 10 and the lower ruler part 11 are matched to form complete figure structure.

[0025] Further, a plurality of rotating connecting parts 14 are installed equidistantly at the joint surface positions of the upper ruler part 10 and the lower ruler part 11, the upper ruler part 10 and the lower ruler part 11 are connected by rotating the rotating connecting part 14, specifically, the upper ruler part 10 and the lower ruler part 11 are provided with groove structures at the positions where the rotating connecting part 14 is installed, and the rotating connecting part 14 is installed in the groove structures on the upper ruler part 10 and the lower ruler part 11 by two shafts.

[0026] Further, a combination recess 102 is formed at the bottom of the upper ruler part 10, the length, width and depth of the combination recess 102 are consistent with the length, width and thickness of the lower ruler part 11, such structure makes the lower surfaces of the upper ruler part 10 and the lower ruler part 11 on the same horizontal plane when the ruler 1 is folded into the first morphology, so as to ensure the application effect of the ruler 1, that is, the bottom is horizontal when using the ruler 1, which does not affect the use of the ruler 1.

[0027] By adopting the above technical solutions:

[0028] The combination ruler is constructed by dividing a ruler 1 into an upper ruler portion 10 and a lower ruler portion 11, which are foldable. Therefore, when the ruler 1 is in a first folded configuration, the ruler 1 is easy to carry and requires little storage space. Furthermore, the functions of the ruler 1 are not affected. When the ruler 1 is in a second unfolded configuration, the semi-pattern grooves 12 on the upper ruler portion 10 and the lower ruler portion 11 are paired to form a complete pattern structure. This provides the user with a complete pattern, solving the problem of insufficient space for patterning due to the small width of the ruler 1.

[0029] Example 2

[0030] On the basis of Example 1, in this embodiment, a plurality of second magnetic portions 13 are installed on the joint surfaces of the upper ruler portion 10 and the lower ruler portion 11. The second magnetic portions 13 enable the joint surfaces of the upper ruler portion 10 and the lower ruler portion 11 to be attracted to each other when the ruler 1 is unfolded into the second form. Such a structural arrangement makes it difficult for the upper ruler portion 10 and the lower ruler portion 11 to be compressed and deformed when the user unfolds the ruler 1 and uses the semi-graphic grooves 12 to form a complete graphic structure, thereby causing deformation of the drawing graphic.

[0031] Furthermore, the free side edge of the lower ruler portion 11 and the edge of the combined recess 102 are provided with mutually adapted slope structures 100. Such a structural arrangement enables the edge of the lower ruler portion 11 to fit with the edge of the combined recess 102 when the ruler 1 is folded into the first form, thereby ensuring that the bottom surface of the upper ruler portion 10 and the lower ruler portion 11 is flat after being folded.

[0032] Furthermore, a plurality of first magnetic portions 101 are embedded in the slope structure 100 on the lower ruler portion 11 and the combined recess 102. The first magnetic portions 101 enable the upper ruler portion 10 and the lower ruler portion 11 to attract each other when the ruler 1 is folded into the first form, making it less likely for abnormal looseness to occur.

[0033] Specifically, the first magnetic attraction portion 101 and the second magnetic attraction portion 13 each include two parts: a magnetic sheet and a metal sheet, wherein the magnetic sheet and the metal sheet can be attracted to each other.

[0034] Furthermore, a turning auxiliary groove 110 is opened at the edge of the lower scale portion 11, and the turning auxiliary groove 110 is used to assist the lower scale portion 11 to turn over and unfold.

[0035] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
