High-portability teaching experiment box for information technology

Abstract

The invention discloses a high-portability teaching experiment box for the information technology. The teaching experiment box comprises a box body; a tapered slot is reserved in the inner wall of thebottom of the box body; a screw hole is formed in the part, approaching the bottom of the tapered slot, of the bottom of the box body; and a choke plug is arranged in the screw hole in a screw jointmanner. A spacing plate is welded to the part, being close to the middle part, of the inner wall of the box body; hydraulic oil is reserved below the spacing plate; a supporting oil cylinder and a power oil cylinder are fixed at parts, being close to the inner walls of two opposite sides of the box body, of the bottom of the spacing plate by bolts; two plugging holes are formed in the bottom of each of the supporting oil cylinder and the power oil cylinder; and an outlet pipe and a conveying pipe are plugged into the two plugging holes at the bottom of the supporting oil cylinder respectivelyand a solenoid valve is arranged at the middle part of the outlet pipe. According to the invention, the flowing direction of the hydraulic oil can be observed obviously when the internal hydraulic oilcirculates internally; and the up-down movement of the tray at the top of the top rod is observed obviously, so that the hydraulic transmission principle is easy to understand. Therefore, the teaching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of teaching experiment boxes, in particular to a portable teaching experiment box for information technology. Background technique [0002] At present, the known hydraulic teaching system generally adopts hydraulic transmission, and the teaching experiment bench is bulky and expensive, requiring special personnel to perform demonstration operation experiments, and data collection mostly uses mechanical instruments combined with manual collection. For this kind of hydraulic teaching system, it has many shortcomings and deficiencies: oil transmission is used, oil resources are wasted, and the environment is polluted. It is inconvenient for students and teachers to do it in teaching experiments, which affects the enthusiasm and initiative of learning and teaching. sex.

Problems solved by technology

[0002] At present, the known hydraulic teaching system generally adopts hydraulic transmission, and the teaching experiment bench is bulky and expensive, requiring special personnel to conduct demonstration operation experiments, and the data collection mostly adopts mechanical instruments, combined with manual collection.

For this kind of hydraulic teaching system, it has many shortcomings and deficiencies: oil transmission is used, oil resources are wasted, and the environment is polluted. It is inconvenient for students and teachers to do it in teaching experiments, which affects the enthusiasm and initiative of learning and teaching. sex

[0003] Moreover, the existing hydraulic test benches are not easy to carry, so there is a need for a teaching experiment box for hydraulic transmission devices that can simply and clearly demonstrate the principle of hydraulic transmission and facilitate adjustment of correlation coefficients
