Abstract

The utility model is a kind of anti-corner magic square, and comprising hornblock, rib block, middle piece and central shaft, its improvement is：In three exterior angles of the hornblock projecting member is provided with least one exterior angle；The sides adjacent of the rib block and hornblock is provided with holding section, will not thoroughly allow hornblock during magic-square rotary or because " corner " occurs for external force factor.

Description

A kind of anti-corner magic square

Technical field

The utility model is related to educational toy technical field, more particularly to a kind of magic square.

Background technology

Magic square is a kind of educational toy, but magic square motion reduction is upgraded to a kind of athletic competition by increasing fan Motion, the operation sense of magic square and the stability under high-speed rotation are the concern characteristics of player.

Existing magic square, including second order, three ranks, quadravalence and multistage magic square, wherein the most popular with three rank magic squares.Magic square The position and direction of combination and assembly, block and block are not unordered.If a magic square reduced, one of angle, An angle is have rotated with external force, this magic square can not just be reduced by " formula ".We are referred to as " corner ".One The magic square of corner, can not be reduced by conventional meanses.And during the games, if magic square there occurs that " corner " has accordingly Punishment.One traditional magic square is than less easily " corner ", because traditional magic square can adjust relatively tight, and the side of block Edge cyclotomy angle is smaller, relatively sharper.And the magic square competed now, compare pursuit fault-tolerance, the fillet of fast hornblock is than larger, rib Block side relevant position can leave corresponding vacancy to increase magic square performance.Elasticity plus adjustment is typically all more loose, from And have than larger opening degree, cause hornblock to be particularly easy to " corner ".Have and compete many times, influenceed because of the generation of " corner " Create new record.Therefore, anti-corner turns into the problem of needing to consider in the design of present magic square.No matter this defect is to daily Amusement and match all cause puzzlement.

Utility model content

The technical problem that the utility model is solved is to allow a magic square ensure that enough fault-tolerant and adjust more loose On the premise of will not also thoroughly occur corner.

The technological means that the utility model is used is as described below.

A kind of anti-corner magic square, comprising hornblock, rib block, middle piece and central shaft, its improvement is：Three of the hornblock are outer At least one in angle is provided with projecting member at exterior angle；The sides adjacent of the rib block and hornblock is provided with holding section.

Wherein, the projecting member is the projection extended from exterior angle end to adjacent side, or hook part, whole protuberance Part outer face is curved.

Wherein, the holding section is extended from rib block shell, or is extended from the rib block main body of rib block.

It can also be：The rib block includes the first split component and the second split component, and includes supporting track, the branch Support track is arranged in the middle of two split components, and the holding section is arranged on the supporting track.

Further：The holding section is is arranged in pairs, on the centre position that the supporting track is oppositely arranged on respectively.

Technique effect produced by the utility model：Will not thoroughly allow hornblock during magic-square rotary or because external force because " corner " occurs for element.

Brief description of the drawings

Fig. 2 a and Fig. 2 b are the structural representation that hornblock in the utility model, rib block, middle piece and central shaft cooperate.

Fig. 3 a to Fig. 3 d are the structural representation of hornblock in the utility model.

Fig. 4 a to Fig. 4 d are the structural representation of rib block in the utility model.

Fig. 5 a to Fig. 5 d are hornblock and the structural representation of rib block mutual cooperation in the utility model.

Embodiment

As illustrated in figs. 1A and ib, it is the structural representation of three rank magic squares, and main body is in square, and it is by lumpy part Constituted with the connecting shaft in the closing space surrounded positioned at the plurality of block parts, multiple block parts are specifically included positioned at magic square The hornblock 1 of vertex angle part point, the middle block 2 positioned at each face middle part of magic square and it is installed in corresponding hornblock and middle piece Between rib block 3.Each magic square includes 8 hornblocks, 12 rib blocks and 6 middle blocks.

As shown in Figure 2 a and 2 b, it is structural representation that hornblock 1, rib block 3, middle piece 2 and central shaft 4 cooperate, Central shaft 4 includes 6 side's outrigger shafts, is fixed respectively with 6 middle block grafting, and hornblock 1 is inner to set hornblock card angle 1-1, middle piece of 2 lower ends Middle piece of card angle 2-1 is provided with, the inner of rib block 3 sets rib block card angle 3-1, hornblock card angle 1-1, middle piece of card angle 2-1 and rib block card Angle 3-1 complements each other to form the interior contact rotational structure of magic square.

As shown in Fig. 3 a to Fig. 3 d, the hornblock 1 includes hornblock main body 1-2 and 3 pieces of shells, and each hornblock has outside three Angle, exterior angle is not occur a single angle for annexation in three outer surfaces of each face angle block with other faces.Above-mentioned angle Block card angle 1-1 is arranged on hornblock main body 1-2 one end, and the hornblock main body 1-2 other end is extended three groups of grafting rail 1- 4, each described shell medial surface is provided with the inserting groove 1-5 matched with grafting rail 1-4, and three pieces of shells are fixed by connected structure A hornblock is formed in hornblock main body.The technical program emphasis, which is improved, to be, at least one exterior angle in three exterior angles of hornblock Projecting member 1-3 is provided with, optimal mode is that three exterior angles are provided with such projecting member 1-3, projecting member 1-3 Can be the projection extended from exterior angle end to adjacent side, or hook part, whole projecting member 1-3 outer faces are curved.

Next sees the structure of rib block 3, as shown in Fig. 4 a to Fig. 4 d, and the rib block 3 includes rib block main body 3-2, and 2 pieces of shells, Above-mentioned rib block card angle 3-1 is arranged at rib block main body 3-2 one end, and 2 pieces of shells are arranged at the other end.Each rib block and two Individual hornblock is adjacent, and each rib block side adjacent with hornblock is not provided with any contact surface, can be the region of hollow out.In order to angle The projecting member 1-3 formation clampings of block, the rib block 3 is provided with holding section 3-3 with hornblock sides adjacent, and the holding section 3-3 can To be extended from both sides shell, it can also be extended from rib block main body 3-2, as long as can be with above-mentioned projecting member phase clamping .Can also be as shown in the figure in the present embodiment, rib block 3 includes the first split component 3-5 and the second split component 3-6, and Include supporting track 3-4, supporting track 3-4 is arranged in the middle of two split components, the work of connection and support can be played With, therefore corresponding holding section 3-3 is arranged on the supporting track 3-4, preferably described holding section 3-3 is two, respectively relatively On the centre position for being arranged on the supporting track 3-4.

Please refer to shown in Fig. 5 a to Fig. 5 d, it is the structural representation that hornblock 1 and rib block 3 cooperate, and is disclosed Cooperation at the exterior angle of hornblock 1 between projecting member 1-3 and the holding section 3-3 of rib block 3, to avoid the generation of corner phenomenon.
