A multifunctional experimental instrument for university physics and electromagnetism

Abstract

The invention belongs to the technical field of experimental instruments, in particular to a multifunctional experimental instrument for university physics and electromagnetism, comprising a cabinet and a casing, a mounting plate is installed inside the cabinet, and a lifting column with a synchronizing plate is installed on the four corners of the top surface of the mounting plate; The bottom surface of the outer casing is provided with a connecting column with a limiting slot, and a clamping assembly is installed between the outer casing and the synchronizing plate; the clamping assembly includes a limit block and a two-way screw, and the two-way screw is pierced with two limiters for fixing the connecting column. Position block; a lifting column with a synchronizing plate and a spring is installed inside the device cabinet. The spring assists the synchronizing plate to adjust the movement direction, which is convenient for the lifting column to adjust the height of the instrument and achieve the best viewing angle; when idle, the lifting column will store the instrument into the cabinet. The oscilloscope can be easily fixed by the clamping components, and the suction cups on the synchronization board play the role of pre-fixation and support buffer, which is convenient for installation and disassembly, improves the applicable scope of the instrument, and realizes the multi-scenario and multi-functional use of the instrument.

Description

technical field [0001] The invention belongs to the technical field of experimental instruments, and in particular relates to a multifunctional experimental instrument for university physics and electromagnetism. Background technique [0002] With the continuous development of natural science, experimental instruments are very important. In electrical professional experiments, oscilloscopes are electromagnetic experiments. Oscilloscopes are electronic measuring instruments with a wide range of uses. It can transform electrical signals invisible to the naked eye. To form a visible image, the oscilloscope uses a narrow electron beam composed of high-speed electrons to hit the screen coated with fluorescent substances to produce tiny light spots. Under the action of the measured signal, the electron beam draws the change curve of the instantaneous value of the measured signal on the screen.

Problems solved by technology

[0003] However, the electromagnetic experiment instruments are complicated and vary in size. When teaching the experimental instruments in the laboratory, the experimental teachers mostly hold the experimental instruments with their hands so that the students can see the experimental equipment clearly, or put large experimental instruments on the table to explain , there are certain disadvantages in both cases

In the former method, the teacher is very tired and can’t do other things with one hand occupied; in the latter method, it is difficult to realize multi-angle display of the instrument, it is inconvenient to adjust the angle, and it is easy to fall dust when the oscilloscope is not used, which is not easy to clean
