Step 1: Take out the arrangement displayed in the longest part.
Step 2: Take another longest component and cross it with the previous one.
Step 3: Combine the last long part and the cross structure into a vertical three-dimensional structure as shown in the above figure. If you don't understand how the third part is stuck.
Step 4: When the three-dimensional structure of the center is completed, take one piece according to the length specifications of the remaining part and prepare to put it into the three-dimensional structure.
Step 5: Assemble three parts with different lengths from short to long from the bottom of the three-dimensional structure.
Step 6: At this point, all components have been successfully assembled into the central structure, and then fine-tuning is needed for assembly.
Lubansuo, also known as Kongmingsuo, Zilianfang and Nanmu, etc. Legend has it that in the Spring and Autumn Period, in order to test his son's intelligence, Lu Ban made a detachable toy with six sticks and told his son to open it. After a busy night, my son finally opened it. Later generations called this toy Luban Lock. There is also a legend that "Lu Ban Suo" was produced by Zhuge Liang in the Three Kingdoms period according to the principle of Eight Diagrams Metaphysics.
Therefore, Lubansuo is also called Kongmingsuo. Luban lock is composed of six rectangular wooden strips with grooves, two of which bite in three directions, forming a structure in which mortises and tenons are embedded inside. The tenon-mortise structure is the first of its kind in ancient architecture in China. Luban lock is made according to the principle of mortise and tenon combination.
