Description

Technical Field

[0001] The invention relates to an educational toy, a magic ruler, and in particular to a mounting structure of the magic ruler. Background Art

[0002] Rubik's Snake (also known as the magic ruler) was created by Erno Rubik, a Hungarian Rubik's puzzle toy with high degree of freedom invented in the 1970s.

[0003] At present, the traditional magic ruler (hereinafter referred to as the magic ruler) is a triangular product made of elastic hard plastic. It consists of a main body (one side of the main body is a raised elastic point and the other side is a groove) and a cover to form a single-section magic ruler, and then an elastic nylon rope is passed through 24 sections (or 36 sections, 48 ​​sections, etc.) of the single-section magic ruler to form a complete multi-section magic ruler. The way to play is to continuously rotate the angle of the single-section magic ruler and use the combination of multiple sections of the magic ruler to form different shapes.

[0004] Since its introduction, the magic ruler has been popular all over the world because of its strong educational function for humans. The magic ruler is easy to understand, changeable and flexible. In order to play it well, the player must be able to concentrate, think continuously, and not be impatient to gradually play it well. In a sense, the magic ruler has become a toy for special intellectual development and a toy for testing the player's intelligence level and maturity, thus attracting batches of players.

[0005] The traditional magic ruler uses a positioning method of spring points and grooves when rotating. Multiple sections of the magic ruler are rotated 90 degrees each time to form different patterns. Once the nylon rope breaks, it is difficult for players to repair it by themselves. The toughness of the nylon rope will gradually decrease over time, and the magic ruler will become loose. The spring magic ruler uses a spring as a connection method, which allows the magic ruler to maintain its elastic effect during long-term use and is not prone to failure.

[0006] However, the existing spring has the following defects:

[0007] 1. When the magic ruler rotates between 10 and 80 degrees, the spring compression value increases, the friction between the spring point and the plane increases, and the corresponding rotational force also increases;

[0008] 2. The positioning method of the elastic point combined with the groove will gradually reduce the positioning effect due to long-term wear and tear, thus affecting the rotation feel;

[0009] 3. Some existing magic rulers can be disassembled by disassembly tools, but they themselves rely on disassembly tools. It is difficult to complete the disassembly of single-section magic rulers without disassembly tools, which limits the variability of the magic ruler itself. In addition, parts will be constantly worn during the disassembly process, eventually leading to weakened functions or even failure.

[0010] 4. Most magic rulers on the market are fixed by the friction between the main body and the cover. When the whole falls and is damaged, the small internal parts will be exposed, which is extremely dangerous for children who are too young. Summary of the invention

[0011] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a magic ruler structure with strong stability, good positioning performance and convenient disassembly.

[0012] In order to solve the above technical problems, the technical solution adopted by the present invention is a positioning and detachable changeable magic ruler installation structure, comprising a plurality of magic ruler units, adjacent magic ruler units are spliced ​​with each other; each magic ruler unit comprises a shell, an end cover, a button and a buckle; the shell is in the shape of a triangular prism, wherein the long side surface is an opening, and the two short side surfaces are respectively provided with a buckle installation groove and a buckle receiving groove; the buckle can be movably installed in the buckle installation groove, and when the buckle extends out of the shell, it is buckled with the buckle receiving groove of the shell of another magic ruler unit; the end cover covers the opening of the shell and is fixedly connected to the shell; an active area is provided in the middle of the end cover, and the button is installed in the active area; the inner end of the button is provided with an inclined surface for squeezing the buckle.

[0013] A further technical solution is that the fastener includes a fastener shaft, a spring retaining ring and a spring; both ends of the fastener shaft are convex rings protruding radially; the convex ring at the outer end of the fastener shaft passes through the center hole of the spring retaining ring, and the diameter of the convex ring at the inner end of the fastener shaft is larger than the inner diameter of the center hole of the spring retaining ring; the spring is clamped between the convex ring at the inner end of the fastener shaft and the spring retaining ring; the spring retaining ring is installed in the fastener installation groove of the outer shell.

[0014] A further technical solution is that the snap receiving groove of the shell includes a large slot hole and a small slot hole that are interconnected, the aperture of the large slot hole is larger than the diameter of the outer end convex ring of the snap shaft, and the aperture of the small slot hole matches the diameter of the shaft portion of the snap shaft close to the outer end convex ring.

[0015] A further technical solution is that a plurality of positioning magnets are installed on the inner surfaces of the two short side surfaces of the shell, and the magnets installed on the two short side surfaces have opposite polarities.

[0016] A further technical solution is that there are four magnets on the short side of the shell, which are respectively installed at the four end corners of the side.

[0017] A further technical solution is that a plurality of protrusions are provided on the inner surface of the end cover, and the positions of the protrusions match the magnets.

[0018] A further technical solution is that the outer surface of one short side of the shell is provided with a positioning convex point, the outer surface of the other short side is provided with a plurality of positioning concave points, and a groove transition surface is provided between the positioning concave points.

[0019] A further technical solution is that the depths of both ends of the groove transition surface are smaller than the depth of the middle portion.

[0020] The magnetically positioned and detachable changeable magic ruler installation structure of the present invention pushes out the buckle shaft through a button and connects with another section of the magic ruler, so that the whole section of the magic ruler can be separated or connected from any position, and the installation is simple and stable.
