Description

Positioning detachable changeable magic ruler mounting structure

Technical Field

The utility model relates to a changeable magic chi of educational toy, concretely relates to mounting structure of changeable magic chi.

Background

The changeable magic ruler Rubik's Snake (also called magic ruler) is made of Errono Robbick (R) (A. B. C. A. B. A. changeable magic ruler Rubk's Snake (also called magic ruler) is composed of Errono's, Robink's, and

rubik) in the 70 s utility model high-freedom puzzles.

At present, the traditional changeable magic ruler (hereinafter referred to as magic ruler) is a triangular product made of elastic hard plastic. The magic ruler comprises 1 main body (one surface of the main body is a convex elastic point, and the other surface of the main body is a groove), 1 surface cover forms a single-section magic ruler, and then a nylon rope with elasticity penetrates through 24 sections (or 36 sections, 48 sections and the like) of the single-section magic ruler to form a complete multi-section magic ruler. The playing method is that different shapes are spliced by combining multiple sections of magic rulers by continuously rotating the angle of a single section of magic ruler.

Since the advent of the magic ruler, the magic ruler has strong intelligence-developing function for human beings, so the magic ruler is popular and widely understandable, and has strong flexibility, and when the magic ruler is played well, players need to concentrate on the intelligence, think continuously, and play well gradually, so the magic ruler becomes a toy for developing special intelligence and a toy for checking the intelligence level and maturity of the players, thereby attracting a batch of players.

According to the traditional magic ruler, different patterns are combined by rotating the multiple sections of magic ruler for 90 degrees each time in a positioning mode that elastic points are matched with grooves during rotation, once a nylon rope is broken, a player is difficult to repair the nylon rope by himself, the toughness of the nylon rope is gradually reduced along with the use time, and the magic ruler is loosened; the spring magic ruler adopts the spring as a connection mode, so that the magic ruler can keep the elastic effect in the long-term use process and is not easy to lose efficacy.

However, the existing spring has the following defects:

1. when the magic ruler rotates by 10 degrees to 80 degrees, the compression value of the spring is increased, the friction force between the elastic point and the plane is increased, and the corresponding rotating force is also increased;

2. the positioning mode of the spring point matched with the groove can cause the gradual reduction of the positioning effect due to long-term use abrasion, thereby further influencing the rotating hand feeling;

3. some existing magic rulers can be disassembled through a disassembling tool, but the existing magic ruler depends on the disassembling tool, so that the disassembly of single magic ruler is difficult to complete without the disassembling tool, the variability of the magic ruler is limited, parts are continuously abraded in the disassembling process, and finally the function is weakened or even the magic ruler is invalid;

4. most magic rulers in the market are fixed through the friction force between the main body and the face cover, and when the whole falling damage happens, the small parts in the inside can be exposed outside, so that the magic ruler has great danger for children with too low age.
