Description

A kind of spliced Block structural unit
Technical field
The present invention relates to a kind of block toy, specifically it is related to a kind of spliced Block structural unit.
Background technology
In prior art, there are various spliced block toys, such as high building blocks of pleasure etc., as the type building blocks are conducive to The manipulative ability of child and the culture of space imagining ability, and very popular.
Spliced Block structural unit of the prior art have as shown in figure 1, spliced Block structural unit 10 ' be cube structure, A wherein joint face 11 ' is provided with two rounding square boss 12 ' and two square indentations 13 ', rounding square Raised 12 ' are diagonally crisscross arranged with square indentations 13 ', and remaining joint face is provided with four square indentations, on joint face 11 ' The foursquare projection of rounding be not only adapted with the square indentations 13 ' on joint face 11 ' and with remaining joint face on Square indentations are also adapted.The spliced Block structural unit of this kind of structure can realize the bridging of various ways, and composite behaviour is good, makes Type enriches, the degree of freedom height of combination, and the effect of moulding is good, but, but there are problems with:
1st, when some summit adjacent two or three grooves are while when grafting two or three is raised, it is impossible to protect Card is fitted close and two or three projections are interfered.
2nd, multiple cross-over mode cannot be realized.
3rd, as square boss and square indentations are not stepped down when coordinating, its production difficulty increases, and plug dynamics It is difficult to control to.
4th, projection is more easily damaged.
Content of the invention
In view of the drawbacks described above of prior art, the technical problem to be solved be provide one kind can realize multiple The spliced Block structural unit of cross-over mode, when some summit adjacent two or three grooves while grafting two or three When individual raised, this kind of spliced Block structural unit can guarantee that tight fit and two or three projections are non-interference.
In order to solve above-mentioned technical problem, the present invention provides a kind of spliced Block structural unit, with frame and multiple connections Face, wherein a joint face are defined as the first joint face, and remaining joint face is defined as the second joint face, sets on first joint face Have two the first grooves and two projections, described two raised corresponding can be adapted with described two first grooves, described second Joint face is provided with four the second grooves that can be adapted with the projection, and described two projections are distributed in first joint face On one pair of which linea angulata on, described two first grooves are distributed on the wherein another diagonal on first joint face, Four second grooves are distributed in diagonal on the second joint face which is located two-by-two, and the projection is divided from base portion to top For connecting portion and extension, the connecting portion can be with first groove or the second groove tight fit, and the height of the connecting portion Degree is not more than the width of the frame formed by the first joint face edge to first groove, by the connection on the extension The lateral surface that portion extends is for being bordered by face, 45 degree of the angle=being bordered by between face and first joint face;By a projection The distance between center and its nearest outer side edges of frame corresponding are defined as W1, and another raised center is with corresponding which is nearest The distance between outer side edges of frame are defined as W2, and the center of above-mentioned two projection is defined with the difference of the distance of same frame respectively For W3, then the relation between W1, W2, W3 is:W1:W2:W3=1:1:2.
The present inventor is had found in practical work, is concerned only with the projection for cooperating from conventional building blocks and groove is different, is spelled Connect each raised height in formula building blocks extremely important with matching relationship between the width of frame, also, between several projections Also extreme influence the splicing ability of the spliced building blocks to the proportionate relationship of centre distance.
Test through long-term research and repeatedly, present inventors have proposed such scheme, by each part dimension relation Cooperate and control so that the spliced Block structural unit conveniently can must realize multiple cross-over mode, and have production The little grade of difficulty is a little.
Above-mentioned spliced Block structural unit, wherein, first groove and the second groove protrude on the inside of which respectively and arrange Limited location muscle.
Above-mentioned spliced Block structural unit, wherein, the height of the extension is zero.That is to say that the projection only includes institute Connecting portion is stated, makes the spliced building blocks have the advantages that succinct, attractive in appearance and simple production process.
Above-mentioned spliced Block structural unit, wherein, the cross sectional shape of the connecting portion and/or extension for circle or has Two symmetric figures for being mutually perpendicular to axis of symmetry, the cross sectional shape of first groove for circular or be mutually perpendicular to two right Claim the symmetric figure of axle.It should be understood that the shape of the connecting portion and the first groove is unrestricted, it is only necessary to can be mutually tight Join, the effect being connected is reached, but, by above-mentioned setting, the spliced building blocks can be realized with 90 degree as list Flexible splicing can still be realized after the conversion direction of position.
Above-mentioned spliced Block structural unit, wherein, the cross sectional shape of the connecting portion and/or extension is square, institute The cross sectional shape for stating the first groove is square, and the limit rib number on each first groove is two, two limit ribs It is located on two adjacent edges or two relative edges of the first groove respectively.Preferably, the cross sectional shape of connecting portion and the first groove is set For square, the problem that can avoid producing relative rotation when realizing bridging between building blocks.And only using two limit ribs, join Close the side wall of groove, so that it may the close-fitting of raised and the first groove is realized, with simple structure, reliable advantage.
Above-mentioned spliced Block structural unit, wherein, the cross sectional shape of the connecting portion and/or extension is square, institute The cross sectional shape for stating the first groove is square, and the limit rib number on each first groove is four, four limit ribs It is located on the four edges of the first groove respectively.
Above-mentioned spliced Block structural unit, wherein, the cross sectional shape of the connecting portion and/or extension for circle or has Two symmetric figures for being mutually perpendicular to axis of symmetry, the cross sectional shape of second groove for circular or be mutually perpendicular to two right Claim the symmetric figure of axle.It should be understood that the shape of the connecting portion and the first groove is unrestricted, it is only necessary to can be mutually tight Join, reach the effect being connected.
Above-mentioned spliced Block structural unit, wherein, the cross sectional shape of the connecting portion and/or extension is square, institute The cross sectional shape for stating the second groove is square, and the limit rib number on each second groove is two, two limit ribs It is located on two adjacent edges or the relative edge of the second groove respectively.Preferably, the cross sectional shape of connecting portion and the second groove is set to Square, the problem that can avoid producing relative rotation when realizing bridging between building blocks.And only using two limit ribs, coordinate The side wall of groove, so that it may realize the close-fitting of raised and the second groove, with simple structure, reliable advantage.
