[0036] two first plate portion 132A and vertical clapboard 138 have formed accommodation section, left side (for example, the groove of opening) left 136A in the left side of vertical clapboard 138.Horizontal connecting plate 134 is with two side plates 132 and vertical clapboard 138 accommodation section (it is about horizontal connecting plate 134 symmetries) that to be divided into two cross sections in formed accommodation section, its right side be the L type, one with the top is referred to as upper right accommodation section 136B, and of below is referred to as accommodation section, bottom right 136C (not shown).
[0037] at least one in above-mentioned three accommodation sections can be used for receiving the constructional pieces 170 of suitable shape and size, and guarantees the connection that constructional pieces is more firm by the strain of the 3rd building blocks connector 130.Compare (under the situation of same size and material) with the accommodation section of the first building blocks connector 110 or the L type accommodation section of the second building blocks connector 120, the contact area of upper right accommodation section 136B and accommodation section, bottom right 136C and constructional pieces 170 is bigger, therefore can obtain the combination more firm, can bear bigger pulling force and do not throw off than above-mentioned both.Further preferably, the second plate portion 132B ' (not shown) that one of at least is suitable for receiving another the 3rd building blocks connector 130 ' of above-mentioned three accommodation sections.
[0038] for example, the length of horizontal connecting plate 134 can equal the length of the false add epipleural part 132B of plate portion 132A length.Further, distance between the side plate 132 (transverse width of horizontal connecting plate 134 just) equals or is slightly larger than the width of side plate 132 substantially, can be inserted in the accommodation section of another identical building blocks connector with assurance side plate 132, and rely on strain firmly to link together.
[0039] further, in aforesaid three kinds of building blocks connectors, outer surface at parallel side plate also can be provided with some circular protrusions (as 118 among Fig. 1, among among Fig. 2 129 and Fig. 3 139), two side surfaces of horizontal connecting plate can be provided with some circular pit (as 119 among Fig. 1, among among Fig. 2 123 and Fig. 3 133), can cooperate pit corresponding on another building blocks connector like this by the projection that makes a building blocks connector, thereby the strain of the projection of utilization and pit links together a plurality of building blocks connectors.The shape that it will be appreciated by those skilled in the art that described projection and pit also can be other shape, and is for example square, triangle or the like.Described a plurality of projection or a plurality of pit can be spaced on the surface at place separately.Further, in aforesaid three kinds of building blocks connectors, two parallel side plates have groove along boundary line (as 117 among Fig. 1 at the intersection with horizontal connecting plate, among among Fig. 2 125 and Fig. 3 135), described groove can be used for holding and fixing the parallel side plate of another building blocks connector, thereby a plurality of building blocks connectors can be linked at together.
[0040] Fig. 4 shows a modular system 200, and it has used multiple according to building blocks connector of the present utility model (as: 110,120,130), is used for firmly connecting constructional pieces 170.Constructional pieces 170 includes but not limited to cuboid building blocks 172, triangle constructional pieces 174, beam shape constructional pieces 176.
[0041] as exemplary explanation, in Fig. 4 upper center, first accommodation section of the first building blocks connector 110A is firmly connecting a cuboid constructional pieces 172, and the side side plate of the first building blocks connector 110A is embedded in first accommodation section of another first building blocks connector 110B simultaneously.In second accommodation section of the first building blocks connector 110B, embedded another the first building blocks connector 110C similarly.Receive in second accommodation section of the first building blocks connector 110C beam shape constructional pieces 176 is arranged.
[0042] similarly, right side below Fig. 4, the second building blocks connector 120 can utilize that it is upper left, lower-left, upper right accommodation section receive cuboid constructional pieces 172 respectively.At the middle part of Fig. 4, first accommodation section of another first building blocks connector combines triangle constructional pieces 174, and its second accommodation section is connecting two cuboid constructional pieces 172.
[0043] Fig. 5 shows modular system 300, and it has also used multiple according to building blocks connector of the present utility model (as: 110,120,130). Building blocks connector 130A, 130B, 130C, 130D, 130E, 110A, 110B, 110C, 120A, 120B can interconnect fixing by accommodation section separately as can see from Figure 5, perhaps can interconnect by projection on the parallel side plate outer surface of each building blocks connector and the pit on the horizontal connecting plate both side surface fixing, thereby be independent of constructional pieces and build together.It will be understood by those skilled in the art that according to modular system of the present utility model and can only comprise according to building blocks connector of the present utility model.
[0044] Fig. 6 shows modular system 400, and except that according to building blocks connector of the present utility model and the constructional pieces, it has used extra ornament again, for example miniature desk, and person of low position etc., this has more strengthened the interest of modular system.
[0045] further, as shown in Figure 7, aforesaid modular system can comprise rectangle sheet connector 150, two surfaces of this connector all have projection 151, and its width is more than or equal to the distance between two parallel side plates of above-mentioned building blocks connector, thereby can utilize recessed on the horizontal connecting plate of the projection coupling building blocks connector of this sheet connector by brace, and/or the groove that mates by this sheet connector on the parallel side plate of this above-mentioned building blocks connector is connected and fixed a plurality of above-mentioned building blocks connectors.
[0046] those skilled in the art are to be understood that, above-mentioned modular system 200,300 and 400 building method are schematic, the building blocks connector can suitable dimension and the accommodation section of shape receive constructional pieces or building blocks connector, and/or a plurality of building blocks connectors itself can utilize its lip-deep projection and pit and interconnect, and/or can rely on groove on the parallel side plate of building blocks connector, thereby can build and assemble out a large amount of, two dimension miscellaneous or three-dimensional body moulding, for example house etc.Should be noted that in plural constructional pieces can be independent of the building blocks connector and be built together according to modular system of the present utility model.
[0047] though the utility model is illustrated in conjunction with the foregoing description with reference to accompanying drawing, the person of ordinary skill in the field should be appreciated that, under the prerequisite that does not depart from scope and spirit of the present utility model, can carry out various conversion or alternative.Therefore, of the present utility model, be intended to summarize these variations and alternative protection domain is as the criterion with appended claims.
