Description

A kind of middle shaft structure of puzzle toy

Technical field

The utility model relates to a kind of puzzle toy, specifically a kind of middle shaft structure of puzzle toy.

Background technology

Magic square is by the mechanical educational toy of Shandong Bick in invention in 1974, and is the most fashionable in the eighties, multinomial athletic competition take magic square as stage property occurred at the international level, do not decline so far.Gradually magic square becomes a kind of game of competing for speed, in order to improve the rotating property of magic square, existing magic square has structurally passed through improvement repeatedly, being connected between limit piece and hornblock, namely all than former magic square very large improvement had been arranged on " anti-POP " and " fault-tolerance ", greatly improved the limit velocity that magic square rotates; But at present there is not larger improvement for being connected between piece in the magic square and the middle pivotable frame, the post hole that is still middle pivotable frame is set as screwed hole, then be screwed into after therefrom the mesopore of piece passes by a screw and realize in the post hole of middle pivotable frame connecting, and spring is set in middle is placed in the rotating property that screw improves magic square, so the magic square of design is in long-term rotation process, getting loose can appear in connection, thereby causes spring to eject and lose, and need to often adjust check and correction; And the mode that this rotation is tightened can cause six middle pieces to differ with the degree of tightness that is connected of middle pivotable frame, can't realize accurate location, and then cause rotating dumb; When dismounting, all need to utilize screwdriver could realize dismounting as instrument in addition, very inconvenient.

Summary of the invention

For the existing problem of above-mentioned prior art, the purpose of this utility model provides a kind of middle shaft structure of puzzle toy, it is installed on the magic square after piece accurate positioning in each of magic square, and be connected firmly, rotate flexibly, also be convenient to disassembling, assembling and replacing.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of middle shaft structure of puzzle toy, comprise with the middle pivotable frame in six post holes and the axis joint pin that is connected with six post holes of middle pivotable frame, be characterized in that described axis joint pin includes the axle bolt and is placed in axle bolt afterbody fixture, the head end of described axle bolt is plugged in the post hole of middle pivotable frame, the afterbody of described axle bolt stretch in the mesopore of piece in the magic square and by the fixture adjustable ground fix realize in piece be connected with middle pivotable frame.

Wherein, for the rotating property that improves magic square and guarantee that spring is difficult for losing, above-mentioned axis joint pin also includes spring, described spring is inserted in to the axle bolt head from above-mentioned axle bolt afterbody, and described spring is sandwiched between axle bolt head and the post hole inner face and being connected between piece and the middle pivotable frame has elasticity in realizing when the axle bolt inserts the post hole of above-mentioned middle pivotable frame.

For further guarantee magic square when the high speed rotating axle bolt not therefrom pivotable frame get loose, the head of above-mentioned axle bolt is provided with diameter greater than the axle cap of axle bolt, the post hole of above-mentioned middle pivotable frame is designed to the stepped bore on three rank, the hole that wherein is positioned at diameter maximum is accommodating for the axle cap of axle bolt, hole in the middle of being positioned at is accommodating for above-mentioned spring, and the hole of diameter minimum that is positioned at outermost is accommodating and stretch out for the axle bolt.

For ease of assembly and guarantee that magic square all need not by any instrument in disassembly process, above-mentioned middle pivotable frame is comprised of the two halves shell frame docking of symmetry, be respectively equipped with inserting column and jack on the interface of described two halves shell frame, plug by inserting column and jack and realize that two halves shell frame links into an integrated entity.

Being connected degree of tightness and can regulating for piece in realizing and middle pivotable frame, the afterbody of above-mentioned axle bolt is provided with several flange collars that is intervally arranged, the above-mentioned fixing piece correspondence is designed to regulating sleeve, described regulating sleeve is provided with the endoporus that cooperates with flange collar, and piece and middle pivotable frame was connected tightness and can regulates during the flange collar of different high and low positions socket-connected and realizes on the endoporus by regulating sleeve and the axle bolt.

In order all to need not in the process that realizes piece in the dismounting by any instrument, above-mentioned regulating sleeve is designed to the cross section that the two halves valve jacket by symmetry forms and is "T"-shaped cylindrical body, be respectively equipped with inserting column and jack on the interface of described two halves valve jacket, plug by inserting column and jack and realize that the two halves valve jacket links into an integrated entity; Further be connected firmly in order to guarantee, above-mentioned fixing piece also includes garter spring, and described garter spring is placed on the little cylinder of the diameter of above-mentioned regulating sleeve and realizes the banding regulating sleeve.

The utility model is owing to adopt the axis joint pin is designed to the structure that includes the axle bolt and be placed in axle bolt afterbody fixture, be plugged in by the head end with the axle bolt in the post hole of middle pivotable frame, and the afterbody of axle bolt stretches in the mesopore of piece in the magic square and by the fixture adjustable ground fix realize in piece be connected with middle pivotable frame, because the head of axle bolt does not therefrom get loose in the pivotable frame, axle bolt and middle also fix by fixture and can not get loose, therefore effectively guarantee that magic square can be not loose in long-term rotation process or make the magic square dislocation yet, firm and reliable connection, and by the be connected tightness of piece in regulating fixture and the fixed position of axle bolt can changing with middle pivotable frame, so can be according to player's personal habits hobby adjusting elasticity, and regulate accurately quick, the tightness that guarantees piece in all directions is identical, make whole magic square be in best mated condition, help to improve the flexible performance that magic square rotates; Again because the axis joint pin also includes spring, and this spring is sandwiched between axle bolt head and the post hole inner face, and the rotating property that this spring not only further improves magic square is set, and spring is arranged in pivotable frame and can guarantees that dismounting magic square process can not lose; Again since middle pivotable frame and regulating sleeve all be double design and inserting column be set and jack is realized being connected and fixed at interface, and cuff or garter spring banding be set outside it, not only guarantee to be connected firmly, and in disassembly process, need not by any instrument, convenient to operation.In sum, the middle shaft structure of puzzle toy of the present utility model, its design is ingenious, not only make piece accurate positioning in each after being installed on the magic square, and connection is more firm, rotates the flexibility height, also is convenient to disassembling, assembling and replacing, efficiently solve the defect problem of existing magic square axis, can be widely used on the puzzle toy of various different ranks.

The utility model is described in further detail below in conjunction with drawings and Examples.
