The invention discloses a manufacturing method of a storage chair. The method comprises the following steps that A, a reverse trapezoidal square body structure wood block is selected, a chiseling and planning
machine is used for hollowing the middle of the reverse trapezoidal square body wood block, a reverse trapezoidal
pipe cavity structure is formed, the bottom surface is of a 40cm*40cm opening structure, an upper opening is an opening being 50cm*50cm, in addition, the upper opening is communicated at a lower opening, one wood plate with the length being 60cm, the width being 50cm and the thickness being 5cm is selected, the chiseling and planning
machine is used on one end of the wood plate, a hole being 40cm*40cm is chiseled, the other end of the wood plate is polished by a
polishing machine, a chair surface is manufactured, the hole formed in one end of the wood plate is matched with a bottom opening of the reverse trapezoidal
pipe cavity structure, the reverse trapezoidal
pipe cavity structure is reversely buckled on the wood plate so that the bottom opening of the reverse trapezoid is matched with the opening formed in one end of the wood plate, in addition, a 120-degree included angle is formed between the reverse trapezoidal pipe cavity structure and the wood plate, and screws are used for fixed connection. The manufacturing method has the advantages that the manufacturing method is simple, the structure of the manufactured product is simple, the intensity is high, articles can be conveniently placed and taken, and the storage volume is increased.
