Description

Technical Field

[0001] The utility model specifically relates to a magic ruler rotation positioning connection assembly. Background Art

[0002] A magic ruler is formed by movably connecting several modules through a hinged structure. The shape of the module is usually an isosceles triangular prism. The hinged structure generally consists of a connecting rod and a spring to ensure good rotatability, fitting degree, and elastic mobility in the hinged axial direction between the modules. Due to its specific structure and connection method, the magic ruler has the advantages of free deformation and infinite expansion. The operator can transform different three-dimensional shapes by randomly twisting some modules of the magic ruler. However, for a specific shape constructed, there is often no suitable positioning device between the modules, and it can only be fixed with the operator's body or auxiliary tools. As the length of the magic ruler increases, the operator often has no extra strength or enough auxiliary tools to achieve fixation. Some magic ruler modules on the market that can be positioned either achieve fixation by increasing the fitting degree between the modules or by adding additional positioning devices, which brings certain operation difficulties, or increases the assembly difficulty, occupies the limited space inside the module, and restricts the expansion of the module, usually not being satisfactory.

[0031] In this embodiment, the positioning ring 3 is fixed on the connection surface cover plate of one module, and the turntable 1 can be directly fixed to another module by rivets or nuts, or connected through the fixing parts on another module; specifically, the turntable 1 is provided with two semi - circular grooves 12, and a semi - circular convex column 4 is correspondingly arranged at the connection surface cover plate of another module, and the semi - circular convex column 4 is inserted into the semi - circular groove 12 to achieve quick assembly between modules in a male - female plug - in manner.

[0032] In this embodiment, the elastic member 2 includes a spring 21, and end blocks 22 are fixedly connected to both ends of the spring 21. The end block 22 includes a connecting portion 23 and a top portion 25. The connecting portion 23 is connected to the spring 21. The connecting portion 23 is provided with a limiting step 24. The limiting step 24 is arranged on the side of the elastic member 2 close to the turntable 1. A convex rib 14 is formed on the edge of the turntable 1. The limiting step 24 abuts against the convex rib 14 of the turntable 1 for limiting, so as to prevent the end block 22 from completely coming out of the card slot 11. The top portion 25 has a smooth surface, extends out of the edge of the turntable 1 along the diameter direction, or retracts into the turntable 1 after being squeezed.

[0033] In this embodiment, the positioning ring 3 has a wavy inner wall. The positioning grooves 31 are symmetrically and equidistantly arranged on the inner wall of the positioning ring 3. Convex blocks 32 are formed on the inner wall of the positioning ring 3 between adjacent positioning grooves 31. The positioning grooves 31 are smoothly transitioned through the convex blocks 32.

[0034] In this embodiment, the turntable 1 is divided into two semi-circular grooves 12 by the card slot 11. Through holes 13 and 15 are opened inside the semi-circular grooves 12. The through hole 15 is used to install rivets or nuts, etc. to fix the turntable 1 and the module connection cover plate. Since a semi-circular convex column 4 with a shape adapted to the semi-circular groove is provided on the connection cover plate in this embodiment, for more stable connection, the number of through holes 15 is set to 4, and the turntable 1 and the semi-circular convex column 4 are locked and fixed by nuts. Elastic conductive contacts 5, etc. are installed in the through hole 13, and in cooperation with structures such as a conductive ring provided at the bottom of the hollow portion of the positioning ring 3, the electrical connection of the module can be realized.

[0035] Since the centers of the turntable 1 and the positioning ring 3 coincide with the rotation center of the connection surface, when adjacent modules of the magic ruler rotate, the turntable 1 and the positioning ring 3 rotate relative to each other. The end blocks 22 at both ends of the elastic member 2 are squeezed by the convex blocks 32 on the inner wall, the top portion 25 retracts into the turntable 1, and the spring 21 is compressed, which is convenient for rotation; as the rotation continues, under the action of the spring 21, the end blocks 22 abut against the convex blocks 32 and gradually move outward to the transition surface between the positioning grooves 31; when the rotation angle reaches the position where the positioning groove 31 is located, both ends of the elastic member 2 completely pop out, and the top portion 25 of the end block 22 is clamped in the positioning groove 31 to achieve positioning. This embodiment can realize the rotation and clamping fixation of the module at a set angle, with smooth operation and good module expansion performance.
