Drawing measuring scale storage device utilizing adsorption principle

Abstract

The invention discloses a drawing measuring scale storage device utilizing the adsorption principle. The drawing measuring scale storage device comprises a storage box and a bottom column, a layeringplate is transversely and fixedly connected to the middle of the interior of the storage box, the interior of the storage box is divided into an upper part and a lower part by the layering plate, a plurality of movable holes are formed in the surface of the layering plate, a position, located inside the storage box, on the lower end of the layering plate is slidably connected with a push plate, and the push plate divides a lower layer area of the layering plate into two isolated different areas. According to the drawing measuring scale storage device utilizing the adsorption principle, by arranging the layering plate, the adsorption column and other structures, the density of gas above the layering plate is increased, the pressure above the layering plate is increased, and therefore the air pressure difference is formed between the upper end and the lower end of the layering plate, a measuring scale placed at the upper ends of the movable holes is subjected to pressure from air pressure, and the measuring scale is fixed on the layering plate, so that disappearance of scales of the measuring scale due to friction caused by shaking of the measuring scale in the storage box is prevented.

Description

technical field [0001] The invention relates to the storage field of drawing rulers, in particular to a drawing measuring ruler storage device utilizing the principle of adsorption. Background technique [0002] Rulers, also known as measuring rulers and scales, are tools used to draw line segments (especially straight ones) and measure length. There are usually scales on the ruler to measure length. Some rulers have special shapes such as letters or circles in the middle. Holes are convenient for users to draw pictures. They are usually used to measure and calculate lengths. They are generally divided into tape measure, vernier caliper, square ruler, and ruler. . [0003] At present, when protecting some drawing rulers, the measuring rulers are generally put into some tool boxes to store and protect the measuring rulers to prevent the measuring rulers from being scratched, but most of the drawing measuring rulers are generally made of plastic material, so when the user pu...

[0003] At present, when protecting some drawing rulers, the measuring rulers are generally put into some tool boxes to store and protect the measuring rulers to prevent the measuring rulers from being scratched, but most of the drawing measuring rulers are generally made of plastic material, so when the user puts multiple plastic measuring rulers of different specifications into the tool box, since the measurement scale lines on the plastic measuring ruler are all made of spray paint, when the user picks up the tool box, The scale line on the surface of the plastic measuring scale inside will be in contact with the surface wall of the toolbox, causing the painted scale line to continuously destroy its integrity during friction, eventually causing the scale line of the measuring scale to disappear, making it impossible to use the measuring scale or measuring stick normally The accuracy of
