Description

Technical Field

[0001] The present invention relates to model building in intellectual development education, and particularly to an inline traditional hole bamboo and wood building model and method for model building, belonging to the technical field of science and education teaching aids. Background Art

[0002] Model building is an important way for teenagers' intellectual development, interest cultivation and thinking expansion. Parents and society also recognize and attach great importance to this method. Various industries related to model building education have also developed rapidly, forming different model building systems. The applicant has conducted in-depth research in this field and formed a set of bamboo (wood) stick, wooden board and building element-based bamboo and wood model building system. This system contains a variety of building elements and develops simultaneously in market promotion and application, attracting the active participation of a large number of teenagers. In this bamboo and wood model building system, the stick is connected to the element through a plug-in hole, and the board is connected to the building element through an open plug-in slot. In order to achieve compatibility between the stick and the board, this model building system adopts an open slot form that can be used to plug in both the stick and the board. For example, in Chinese Patent Application No. 2020222244790 (a wooden board beam member in a play teaching aid building), there are two rows of connection slots on both sides and one row of connection holes in the middle. The connection slots are successively composed of an inner flat slot, an arc-shaped groove and an outer flat slot from the inside to the outside. The arc-shaped groove can be used to plug in the stick member, and the flat slot can be used to plug in the board member. Similar structures are designed in the same or similar way on many elements in this system. For example, in the attached drawings of Chinese Patent Application No. 201105280953 (a play teaching aid building system and building method) Figure 1 , Figure 3 , Figure 6 , Figure 7The components shown; such as Chinese Patent Application No. 2020222244786 (a building connector for play and teaching aids); such as Chinese Patent Application No. 201607072274 (a double-groove clip play and teaching aid connector); such as Chinese Patent Application No. 2016207072081 (a five-hole connector), etc. The above bamboo and wood model building system takes into account the compatibility of rods and boards during research and development. The connectable boards and rod connection grooves (holes) at the edges of the components are in an open form, and the connection of the board components uses an external connection type. The insertion holes (for rod connection) in the middle of the components are in a closed form. In long-term building practice, it is found that the above building system still has the following problems that need to be optimized: When producing this model building system, there is a designed fit between the rods, boards, and connecting components. Usually, the boards and rods are made of wood, and the building components are made of plastic. Both of these materials will expand and contract due to heat, so the quality of their cooperation is affected by temperature, resulting in different connection effects when inserted at different temperatures, and the model building system is significantly affected by seasons and regions with different temperatures. Moreover, the wooden rods and boards are not only affected by temperature, but their external dimensions are also affected by humidity, and the external dimensions cannot be accurately maintained. Before building, it will lead to poor building matching. For example, if the matching is good during building, with the change of temperature and humidity, the built model is likely to be too tight or too loose, or first tight and then loose, affecting the final use effect. The closed holes in the connecting components also have the above problems. Even if the fitting accuracy is good, wear will occur during long-term building applications, and the wear will cause the instability of the built model. The fault tolerance of the existing model building system needs to be solved. This phenomenon also leads to a very cumbersome problem that when selling products, the climatic characteristics of the region need to be considered. Products required in regions with large differences in regional climatic characteristics cannot be produced using a single set of molds, which results in high mold costs and difficult and cumbersome production order management. If the product is used in regions with large climatic differences as the user migrates, the above problems will also occur, causing customer complaints. Therefore, the above problems affect the quality of the entire building system itself and the development of the external market. There is also insufficient clamping force in the connection between the connection groove in the existing model building system and the external connection of the wooden board, especially in the case of using a wooden board with a large area (length).
