Radio communication major teaching experiment shielded box

Abstract

The invention relates to the radio communication major teaching experiment auxiliary equipment technical field, and specially relates to a radio communication major teaching experiment shielded box; the radio communication device can be conveniently placed in the box body, so teachers can easily carry out radio communication major teaching experiments, thus improving practical values. After long term usage, a dirty transparent observation board can be easily wiped, thus allowing teachers to observe the radio communication device in the work chamber, and improving the usage reliability; the shielded box comprises a box body, a storage plate, a base plate, a left electric telescoping cylinder, a right electric telescoping cylinder, a left stay rope, a right stay rope, a left first guide wheel, a left second guide wheel, a left guide ring, a right guide ring, a right first guide wheel, a right second guide wheel, four sets of reset springs, a driving shaft, a front driving rod, a rear driving rod, and a slide column; a rotary through hole penetrating back and forth is arranged in middle of the front end of the box body, and arranged in the lower middle portion of the transparent observation board; a mechanical seal is arranged in the rotary through hole.

Description

technical field [0001] The invention relates to the technical field of attachment devices for teaching experiments of wireless communication specialty, in particular to an isolation box for teaching experiment of wireless communication specialty. Background technique [0002] As we all know, the isolation box for the teaching experiment of wireless communication is an auxiliary device used to isolate and place the wireless communication equipment during the teaching experiment of wireless communication, so as to better test the signal of the wireless communication equipment. It has been widely used in the field of professional teaching experiments; the existing isolating box for teaching experiments of wireless communication majors includes a box body, the inside of the box body is provided with a working chamber, and the top of the box body is provided with a pick-and-place opening. There is a cover plate, the front end of the box is provided with an observation port, and t...

[0002] As we all know, the isolation box for the teaching experiment of wireless communication is an auxiliary device used to isolate and place the wireless communication equipment during the teaching experiment of wireless communication, so as to better test the signal of the wireless communication equipment. It has been widely used in the field of professional teaching experiments; the existing isolating box for teaching experiments of wireless communication majors includes a box body, the inside of the box body is provided with a working chamber, and the top of the box body is provided with a pick-and-place opening. There is a cover plate, the front end of the box is provided with an observation port, and the observation port communicates with the inside of the working chamber, and a transparent observation plate is arranged on the observation port; when the existing isolation box for teaching experiments of wireless communication is used, the isolation box is first placed At the position required by the user, put the wireless communication device into the working cavity, close the cover, issue a signal command to the wireless communication device through the external computer, and then observe the reaction of the wireless communication device through the transparent observation board It is enough to record; in the use of the existing isolation box for teaching experiments of wireless communication, it is found that the wireless communication equipment is inconvenient to take and place inside the box, and it is inconvenient for teachers to carry out teaching experiments of wireless communication, resulting in poor practicability; and transparent After the observation board is used for a long time, it is easy to be dirty and inconvenient to wipe, which affects the teaching staff's observation of the wireless communication equipment inside the working chamber, resulting in low reliability in use
