Portable magnetic absorption Internet-of-things multifunctional teaching device

Abstract

The invention provides a portable magnetic absorption Internet-of-things multifunctional teaching device, relates to the technical field of teaching equipment, and solves problems that on one hand, dust prevention of a jack in a non-use state cannot be realized, on the other hand, a dustproof structure cannot realize auxiliary fixation of a plug at the same time, and vibration type dust removal of the plate body cannot be realized while suspension is realized through structural improvement. The portable magnetic adsorption Internet of Things multifunctional teaching device comprises a demonstration board main body, wherein the demonstration board main body is provided with two suspension seats, wherein a plug is inserted into the demonstration board main body. When an elastic telescopic box stretches, a jack is in a shielding state, and the elastic telescopic box forms a dustproof structure of the jack; the plug is matched with the jack, the plug is provided with a clamping groove A, and the clamping groove A is matched with a head end of the elastic telescopic box; and when the plug is inserted into the jack, the head end of the elastic telescopic box and the clamping groove A are in an inserted state, so auxiliary fixation of the plug can be realized.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, and more particularly, particularly relates to a portable magnetic adsorption Internet of Things multifunctional teaching device. Background technique [0002] With the rapid development of Internet of Things technology, various colleges and vocational schools have successively opened Internet of Things-related majors, and electronic teaching boards need to be used for teaching. [0003] For example, application number: CN201920812077.7, a portable magnetic adsorption IoT multi-functional teaching device, including a portable base, a magnetic adsorption bottom plate, a touch screen, a sensor acquisition module, an actuator control module, a central intelligent gateway and a power supply module, the magnetic adsorption The bottom plate is arranged on the portable base, the touch screen, the sensor acquisition module, the actuator control module and the central intelligent gateway are ar...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a portable magnetically-adsorbed Internet of Things multifunctional teaching device to solve the existing problem that the existing devices generally need to be plugged into a USB when in use, but the existing devices always need to be plugged in when in use. On the one hand, the dustproof of the jack cannot be realized in the non-use state; on the other hand, its dustproof structure cannot realize the auxiliary fixing of the plug at the same time; moreover, the suspension structure of the existing device is single, and it cannot be installed in the socket through structural improvement. The problem of realizing the vibrating dust cleaning of the plate body while realizing the suspension
