Description

Science and education building blocks

Technical field

This utility model is related to a kind of assembled building blocks, is exactly a kind of science and education building blocks.

Background technology

In order to assemble variously-shaped model, such as toy car, robot etc. all must be made existing building blocks Make the different unit body component of sizes different shape.But, first, its processing cost of the part of Multiple Shape excessively is higher, And, erection method is excessively complicated loaded down with trivial details, not easy to get started, interesting not strong.Furthermore, have between variously-shaped different part Specific inserting mode, causes effectively splice between some parts.Above-mentioned factor can all limit the creative think of of assembled person Dimension, meanwhile, also it is unfavorable for the intelligent development of assembled person and the foundation of three dimensions sense.Finally, the volume of existing assembled building blocks It is larger, especially in terms of thickness so that lack installation power set and transmission in the model such as the dolly for assembling or robot The requisite space of device, so as to, it is difficult to assemble can automatic running dolly or robot, the creation for limiting assembled person is empty Between.

Utility model content

To solve the above problems, the purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of science and education product Wood, its building blocks species is less, and plug-to-plug compatibility is good, and, its whole building blocks are plate assembling structure, and thickness is less, spell Dress up and can reserve in model after model the space that be enough to install power set, drive mechanism and all kinds of control devices calmly, Be more beneficial for modelling into the model that can control its autonomous travel, such as it is remote-controlled or little by the cruise of programming autonomous travel Car or robot so as to be not only toy, or the building blocks with test and Teaching Value.Between any two unit body components Can be assembled fixed by connection-peg, and, erection method is easy to learn, can effectively excite the interest of assembled person and create desire, And assembled person can be made to obtain sense of accomplishment during assembled modeling, interest is denseer, so as to greatly improve assembled person's Spatial impression and creativity.

This utility model for achieving the above object, is achieved through the following technical solutions：Science and education building blocks, including at least one list First body, the structure of cell cube is as follows：Cell cube has two the first facings being parallel to each other, between two the first facings Corner at connect four facings of size identical second respectively, four the second facings are parallel two-by-two, and first is square The corner in shape face is connected respectively with the angle of four the second facings, one on the second facing that two of which is parallel to each other Vertically arranged connection-peg, another vertically arranged spliced eye, two unit physical abilitys are vertically coordinated by connection-peg and spliced eye inserts Connect；Two size identical isosceles trapezoid faces of setting between any two second adjacent facings in the cell cube, two The trapezoidal upper bottom in individual isosceles trapezoid face overlaps, and two the trapezoidal of isosceles trapezoid face are gone to the bottom respectively with two the first facings just Quad Sides overlap, and the waist in isosceles trapezoid face overlaps respectively with the square side of the second facing of both sides.

Further to realize the purpose of this utility model, can also employ the following technical solutions：At least two cell cubes according to Secondary being laterally fixedly connected constitutes single association, and connected cell cube is connected by the second facing, and all cell cubes are inserted The direction of joint is identical；The groove of two symmetrical V-arrangements is formed between any two adjacent cell cubes of association.It is arbitrary described The angle of two interior angles at the upper bottom in isosceles trapezoid face is 120 °.Insertion is longitudinally opened up between two described the first facings The fixing hole of two the first facings, fixing hole is communicated with spliced eye.Described fixing hole is circular hole.Described fixing hole Circumferentially direction uniformly longitudinally opens up several through grooves on hole wall.Several association's vertical arrays are several in same plane Association is connected by the first connector of strip, and the two ends homonymy of the first connector respectively arranges a convex section, convex section End first boss is set, the groove fit of two first boss and the association of outermost two, convex section and first The inner side of boss arranges along its length the fin profile and corresponding joint of the fin of middle part evagination, convex section and first boss The groove topography of body side V-arrangement is coincide.The parallel longitudinal arrangement of two associations, the first facing of two associations is put down OK, the second connector of tabular is set between longitudinally adjacent association, and the second connector two ends respectively arrange two claws, claw Tip inside arranges second boss, and claw is connected by second boss with the groove fit of the V-arrangement of longitudinally adjacent association, blocks Pawl and second boss inner side arrange along its length the convex edge of middle part evagination, the convex edge of claw and the convex edge profile of second boss with The profile of the groove of association's side V-arrangement is coincide.Described the second connector middle part opens up avoidance hole.Described claw is two Outward-dipping bar, constitutes V-arrangement draw-in groove between two bars.

The utility model has the advantage of：Both pluggable fixation between each unit body component, staggeredly can mutually sting in splicing again Close locking, model more firmly, be difficult to be scattered.Its design more hommization, joint body component can be connected by various connectors Connect, realize the various models of split and model skeleton, the spatial impression and creativity of assembled person exploitation earlier itself can be made.It is more important , the building-block-splicing into model in leave and facilitate the space for installing power set, drive mechanism and control device enough, and Installation site can be selected arbitrarily as needed, the robot being assembled into, cruise trolley or other automatic dynamic row models is more stepped up Gather, it is compact, operation is more stable, is particularly suitable for mechanical field scientific research and teaching.This utility model may be used also To be applied to machinery, building and field of furniture.For example, material of the present utility model can be each so as to fit being assembled into using metal The skeleton of kind of plant equipment or the skeleton of pavilions, terraces and open halls, may also be employed wooden so as to fit being assembled into various furniture.This practicality is new Type also has the convenient advantage of simple and compact for structure, cheap for manufacturing cost and grafting.
