High-precision instrument storage box for physics teaching experiment

Abstract

The invention belongs to the technical field of storage boxes, and particularly relates to a physics teaching experiment high-precision instrument storage box which comprises a rotary disc type resistance box storage box. The rotary disc type resistance box storage box comprises a box body, and a partition plate is installed in the box body. A box cover is mounted at one end of the box body; the interior of the box body is divided into a plurality of spaces by the partition plates; according to the storage box, the partition plates are arranged, so that every two adjacent rotary disc type resistance boxes are separated, and therefore in the process of carrying the storage box, every two adjacent rotary disc type resistance boxes do not collide due to shaking; by arranging the buffering air bag and the supplementing air bag, when the rotating disc type resistance box is stored in the storage box, the inflated buffering air bag can abut against the rotating disc type resistance box, and shaking of the rotating disc type resistance box in the carrying process is reduced; when the box cover is opened, air in the buffer air bag enters the supplement air bag, so that a user can conveniently insert a hand between the side wall of the rotary disc type resistance box and the buffer air bag to take out the rotary disc type resistance box.

Description

technical field [0001] The invention belongs to the technical field of storage boxes, and in particular relates to a high-precision instrument storage box for physics teaching experiments. Background technique [0002] Precision instruments refer to equipment and devices used to generate and measure precision quantities, including observation, monitoring, measurement, verification, recording, transmission, transformation, display, analysis, processing and control of precision quantities; the precision of physical experiments commonly used by middle school students today Instruments include balance, screw micrometer (micrometer), vernier caliper, thermometer, standard resistance, rotary resistance box, Coulomb torsion balance, etc. Among them, the rotary resistance box can be used for adjustable resistance in DC circuits. With low zero resistance, it is a commonly used instrument in all laboratories, suitable for electrical measurement and other experiments in schools, factor...

Problems solved by technology

[0003] As the most commonly used precision instrument in electrical measurement and electrical experiments, the rotary resistance box is suitable for use when the ambient air temperature is +10°C to +35°C and the relative humidity is 30 to 80%, so multiple resistance boxes are often stored in storage box, and place the storage box storing the resistance box in a cool place in the laboratory equipment room, and before using the resistance box, the teacher will lead the students to move the storage box storing the resistance box from the equipment room to the laboratory. In the experiment, when moving and storing the storage box of the rotary resistance box, it is inevitable that the rotary resistance box in the storage box will shake, and it is easy to cause collisions between multiple rotary resistance boxes in the storage box, thereby As a result, the components inside the rotary resistance box are vibrated and mechanically damaged, causing the adjustment failure of the rotary resistance box, and the disconnection of individual gears of the rotary resistance box; making the rotary resistance box unable to be used normally, resulting in Students cannot perform normal experimental operations, which reduces the effect of students' experimental learning

[0004] In view of this, the present invention proposes a high-precision instrument storage box for physics teaching experiments, which solves the problem of mechanical damage caused by collisions between multiple resistance boxes in the storage box
