Abstract

The utility model discloses a framework and center block structure capable of adjusting hand feel of a magic cube. The framework and center block structure comprises a framework, positioning pins, center blocks, pads, springs and screws, wherein the framework is a three-dimensional cross coordinate shaft with six shaft ends, the center hole of each shaft end is provided with thread M6 inside used for being connected with each center block, the positioning pins which are mounted radially are arranged in the middles of the shaft ends, two ends of the positioning pins are exposed by 3-6 mm, the left half portion of each center block is cylindrical while the right half portion thereof is rectangular, the right end surface of each center block is square, the inner bore of the center block is in the shape of a step big at both ends and small in the middle, the depth of the inner bore on the left side of the center block is 1.5-2 times of the diameter of the inner bore, four circular-arc-shaped positioning grooves are uniformly radially distributed on the left end surface of each center block and used for being used with the positioning pins on the framework so as to realize positioning functions, and the framework and the center blocks are in flexible connection via the pads, the springs and the screws.

Description

Can regulate the skeleton and the central block structure of magic square feel

(1) technical field

The utility model relates to Magic cube, specifically says skeleton and the central block structure that relates to can regulate a kind of magic square the magic square feel from the magic square assembly structure.

(2) background technology

Magic square is a kind of toy for children, and it is applicable to child, pupil, middle school student's intellectual development and tempers teen-age manipulative ability.Magic square was in invention in 1974, and 1977 begin to sell in Hungary, are once once causing sensation the eighties in 20th century in the whole world.One three rank magic square profile is a square, and it has 6 outward appearance planes that vary in color, and each outward appearance plane is made up of 3 * 3 facets; On the stereochemical structure of magic square, three rank magic squares are made up of following routine part:

Six central blocks are in the center on each outward appearance plane, have only a face that color is arranged;

Eight hornblocks are in eight angles of magic square, have three adjacent faces that color is arranged;

12 rib pieces are between central block and the central block, have two adjacent faces that color is arranged;

A skeleton, vertical mutually and crossing formation the by 3 axles, the mid point of each is an intersection point, is three dimensions cross reference axis shape, it has 6 spindle noses.

Central block is installed on the spindle nose, can only rotate around spindle nose, but can not move axially; All rib piece and hornblock are clamped as a whole magic square by skeleton and central block, and each fritter of magic square is that mutual restriction is dodged again mutually.The playing method of magic square is that the initial arrangement state of magic square is upset, and rotates the piece on each outward appearance plane again, makes magic square recover former state.At present, because the design defect of magic square, feel was different when most of magic squares can feel to rotate piece on each outward appearance plane in the process of playing, the pine that has, what have is tight, obviously increases with resistance after a period of time, has so promptly influenced the flexibility of magic square, reduced the speed when playing match again, also the mood to the user has caused negative effect.Grind its reason and mainly be unreasonable the causing of assembly structure of skeleton and central block in the magic square.

(3) summary of the invention

In order to overcome existing magic square the deficiencies in the prior art, the utility model provides skeleton and the central block structure that can regulate the magic square feel in a kind of magic square, it can thoroughly solve each face of magic square when rotated the inconsistent problem of feel and magic square with a period of time after the problem that obviously increases of resistance.

To achieve these goals, the technical solution adopted in the utility model is: skeleton and the central block structure that can regulate the magic square feel in a kind of magic square, it comprises skeleton, alignment pin, central block, pad, spring, screw, and the material of skeleton, alignment pin, central block is a rigid plastics.Wherein skeleton is a three dimensions cross reference axis, its 3 axles are vertical mutually and crossing, the mid point of each is an intersection point, has so just formed 6 spindle noses, is shaped on screw thread M6 in the centre bore of each spindle nose end, dark 10～15mm, be used for concentricity connection, there is a radial hole at the middle part of spindle nose, the alignment pin of radially packing into, 3～6mm is respectively exposed at the alignment pin two ends, and central block can accurately rest on the preposition and nonvoluntary rotation when the effect of alignment pin was the rotation of control magic square; The central block left side is cylindric, right-hand part is a rectangle, the central block right side is a square, it is little that the endoporus of central block is big centre, step-like two ends, one 1 * 45 ° chamfering is arranged at the high order end of central block endoporus, being used to overcome time that magic square uses has grown and can produce burr and increase frictional resistance, the degree of depth of central block left side endoporus is 1.5～2 times of its diameter, can increase the service life of magic square like this, central block left end face radial equipartition has 4 circular arc locating slots, the foursquare corresponding sides of the direction of locating slot and central block right side are perpendicular, are used for being used with the alignment pin on the skeleton, play positioning action; Skeleton forms flexible being connected with central block through pad, spring, screw.

The beneficial effects of the utility model are: the feel of each face of rotation magic square can be regulated by screw, to guarantee the feel unanimity, the resistance unanimity promptly removes to rotate each face of magic square with same power, its angle that rotates through is all the same, is of value to like this improving the speed of playing cube game.

(4) description of drawings

In the accompanying drawing, Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is that A in the overall structure schematic diagram of the present utility model is to view.

Among the figure, 1. skeleton, 2. central block, 3. alignment pin, 4. pad, 5. spring, 6. screw.

(5) specific embodiment

Be assembled into capable further instruction below in conjunction with accompanying drawing to of the present utility model: in the drawings, alignment pin 3 is friction tight to be pressed in the aperture at skeleton 1 spindle nose middle part, central block 2 left sides are sleeved on the spindle nose of skeleton 1, the pad 4 of packing into from the hole on central block 2 right sides, spring 5, screw 6.It should be noted that the pressure that will regulate all springs 5 is consistent mutually, guarantee the flexibility of making peace of all central blocks 2 and the frictional resistance one of skeleton 1 spindle nose.
