Problems solved by technology

However, when the positioning pin is detached from the positioning gear, the operation demonstration table is in a state of free rotation. Since the operation test bench is heavy, the user must keep the positioning pin detached from the positioning gear during the adjustment process, and needs to hold the operation experiment all the time. Especially when the hand holding the operation test bench is suddenly separated from the operation test bench due to a mistake, since the operation demonstration bench is in a state of free rotation, the operation test bench will rotate freely at this time, which will bring great impact to the progress of the experiment. Inconvenience
When operating, you need to release the positioning pin while holding the demonstration table with your hands. It requires two hands to operate, which is inconvenient to operate, and it can only be turned up and down. Students on the side are still inconvenient to observe

Abstract

The invention provides a circuit numerical simulation experiment device. The device can easily flip the testing table panel up and down. Real-time positioning and self-locking during up-down flip canbe achieved, which makes the flip process safe. The testing table panel will not suddenly flipped over on a large scale due to operating errors, which makes it safe and reliable. The invention can flip the test table panel left and right so that students standing on the left and right sides can conveniently observe the experiment table panel. The up-down flip and the left-right flip can be realized by one operating handle and the operation is convenient. The device integrates the functions of transverse flip and up-down flip on an operating rod, so that the teacher is convenient to operate when the test table panel is adjusted. Real-time positioning and self-locking can be achieved during up-down flip and there is no sudden flip due to losing the force, which guarantees the safety of the testing process.

Description

technical field [0001] The invention relates to the field of numerical simulation experiments, in particular to a circuit numerical simulation experiment device. Background technique [0002] The analog and digital circuit experiment course is an essential practice link for college students majoring in electronics, which can cultivate students' ability to analyze and solve problems independently by using the knowledge they have learned. Enhance students' interest in experiments, give full play to students' subjective initiative, cultivate innovative consciousness, and enable students to better grasp the knowledge they have learned. [0003] Most of the convenient analog experiment devices for circuits in the prior art are fixed test benches. When the teacher is explaining and demonstrating, the students standing behind and the students on both sides can easily see the teacher's specific operation clearly. Therefore, in the actual teaching process In order for each student t...
