Oscilloscope protection device for electric automation teaching experiment

Abstract

The invention discloses an oscilloscope protection device for an electric automation teaching experiment, comprising a main body. A front end surface of the main body is provided with a display screenand an operation panel, the operation panel is located at a lower end of the display screen, the lower end surface of the main body is electric telescoping supports at four corners, rear ends of leftand right sides of the main body are provided with grooves, the bottoms of the grooves are provided with venting holes, a U-shaped groove is internally provided with a handle, the handle is composedof a connecting rod and a portable rod, the rear side of the main body is provided with a wiring hole 1 and a wiring hole 2, and the front end surface of the main body is provided with an electrical jack. The oscilloscope protection device has the advantages of simple structure and convenient use, greatly improves the heat dissipation function of the oscilloscope, and prevents the internal workingparts of the oscilloscope from being damaged due to improper heat dissipation, thereby effectively ensuring the safety of the internal working parts of the oscilloscope and ensuring the service lifeof the oscilloscope. The oscilloscope protection device can adjust the height of the oscilloscope, and the function is more comprehensive and convenient for the user to use.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an oscilloscope protection device for electrical automation teaching experiments. Background technique [0002] The oscilloscope is mainly used to display the change of the track of the measured instantaneous value. It can transform the invisible electrical signal into a visible image, which is convenient for people to study the changing process of various electrical phenomena. In the process of electrical automation teaching, it is necessary to Students carry out object teaching, but ordinary oscilloscopes do not have protective devices, and after long-term use, they are easy to wear the surface and reduce the service life. There are certain defects in the use of the patent. On the one hand, there must be a corresponding heat dissipation function. During the use of the oscilloscope, the internal components of the oscilloscope may be damaged due to poor heat dissipatio...

[0002] The oscilloscope is mainly used to display the change of the track of the measured instantaneous value. It can transform the invisible electrical signal into a visible image, which is convenient for people to study the changing process of various electrical phenomena. In the process of electrical automation teaching, it is necessary to Students carry out object teaching, but ordinary oscilloscopes do not have protective devices, and after long-term use, they are easy to wear the surface and reduce the service life. There are certain defects in the use of the patent. On the one hand, there must be a corresponding heat dissipation function. During the use of the oscilloscope, the internal components of the oscilloscope may be damaged due to poor heat dissipation during its own work. On the other hand, the traditional oscilloscope uses an X-shaped The stand is fixed and the height of the display cannot be adjusted
