Description
Technical Field
The utility model relates to a model is built the equipment, in particular to play connecting piece in the teaching aid model is built, belongs to science and education equipment technical field.
Background
The development of the series of products built by the teaching aid is a scientific and educational product aiming at intelligence development of children, and models of different products, equipment, buildings and other articles are produced by different coordination among elements in the building system, so that creativity of the children can be effectively stimulated, thinking space of the children can be expanded, and multi-dimensional cognition and imagination of the children can be enhanced. The existing plastic teaching toy building blocks are mainly divided into pixel particles and special particles, the pixel particles need a large amount of pixel particles to build a certain teaching toy, and the particles increase the difficulty in building the teaching toy when in use; the operation difficulty of a user is increased in the process of building a certain teaching aid; the special particles build a certain toy teaching aid, and the similarity is higher when the appearance is seen; because of its well-defined design purpose, the expansibility is rather low. Especially when playing the teaching aid large-span and connecting, the defect that teaching aid granule part was played to above-mentioned two kinds of defects is more obvious. In order to overcome the defects, the applicant also invests great efforts and funds in the aspect of system research and development, develops a plurality of functional connecting pieces, and can build different system models by adopting the functional connecting pieces, and obtains good effects in practice, the Chinese patent No. 2016105280953 is an example of a teaching and playing building system independently developed by the applicant, in recent years, along with the development of the depth and the breadth of the course, the applicant also develops a plurality of building elements and building systems which can be matched with the system in succession, along with the great increase of the participators, various thought clouds are collected on the building system, various building modes and demands are generated, even some building modes are not thought at all at the beginning of the development of the developers of the set of models, and the demands prompt the developers to develop more functional pieces to match with the thinking requirements of the building participants, among them, although the existing building systems have rich building elements and many connection styles, the circular surface connection and built model have poor sealing and isolation.
Disclosure of Invention
The utility model aims to provide a play teaching aid arc connecting piece in further richening and expanding to present build connecting piece, component system.
In order to realize the purpose of the utility model, the following technical proposal is adopted: the utility model provides a play teaching aid arc connecting piece, includes a plate, the plate be the arc, seted up a plurality of open slots on the arc is global, still seted up confined compound hole on the arc, compound hole circular arc hole and elongated hole have, the circular arc hole communicates with each other with the elongated hole, the both sides end connection in the elongated hole is at the tip in circular arc hole, the circular arc in circular arc hole be greater than 180 degrees.
Further, the method comprises the following steps of; the arc-shaped plate is provided with an arc-shaped bottom surface, the arc-shaped bottom surface is provided with a plurality of open grooves, the number of the open grooves is even, the two open grooves are in one group, and the distance between the two open grooves in each group is equal.
Further, the method comprises the following steps of; the two sides of the elongated hole are parallel to the direction of the connecting line of the middle point of the circular arc and the center of the circular arc.
The utility model discloses an actively beneficial technological effect lies in: the connecting piece is provided with the open slot and the composite hole, the positions can form a connecting structure with the tenon in model building, the arc-shaped plate is adopted, the connecting structure distributed in an arc shape can be formed, the built model is good in isolation, a relatively closed space can be formed, and the arc-shaped plate can also enable the connecting structure to be connected in an expanded mode on the arc surface.

Detailed Description
In order to explain the utility model more fully, the utility model provides an implementation example. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.
The invention is explained in further detail with reference to the drawings, in which the reference symbols are: 1: an arc-shaped plate; 2: an open slot; 3: a composite hole; 4: a circular arc hole; 5: a long hole; 6: a group of open slots; 7: b group of open slots; 8: c group of open slots; 9: and D group of open slots.
As shown in the attached drawing, the arc-shaped plate connecting piece for the teaching aid comprises a plate, wherein the plate is an arc-shaped plate 1, and a plurality of open grooves 2 are formed in the circumferential surface of the arc-shaped plate.
The arc-shaped plate is provided with an arc-shaped bottom surface, the arc-shaped bottom surface is provided with a plurality of open grooves, the number of the open grooves is even, the two open grooves are in one group, and the distance between the two open grooves in each group is equal. The figure shows 8 open slots, namely an A group open slot 6, a B group open slot 7, a C group open slot 8 and a D group open slot 9, wherein the A group open slot 6, the B group open slot 7 and the C group open slot 8 are positioned on the cambered surface, and the D group open slot 9 is positioned on the bottom surface.
The arc-shaped plate is further provided with a closed composite hole 3, the composite hole is provided with an arc hole 4 and an elongated hole 5, the arc hole is communicated with the elongated hole, the end parts of the two sides of the elongated hole are connected with the end part of the arc hole, and the arc of the arc hole is larger than 180 degrees. The two sides of the elongated hole are parallel to the direction of the connecting line of the middle point of the circular arc and the center of the circular arc.
