Multifunctional sensor demonstration fixing device

Abstract

The invention discloses a multifunctional sensor demonstration fixing device which comprises a fixing base and a plurality of sensor fixing units. The sensor fixing units are connected to the upper side end of the fixing base through rotating shafts. The fixing base is provided with two fixing holes. The fixing base is arranged on an experiment table facet through the fixing holes by means of screws. The sensor fixing units are composed of supporting arms and lining plates. One end of each support arm is movably connected to the fixing base through the corresponding rotating shaft, and the other end of each supporting arm is provided with a hinge. The hinges are movably connected with the lining plates. According to the multifunctional sensor demonstration fixing device, the circuit connection of a sensor is demonstrated in a three-dimensional mode, visualization of teaching is achieved, more clear cognition is provided for students, and the working difficulty of teachers is lowered. According to the multifunctional sensor demonstration fixing device, most components are movably connected, the occupied space is less when the device is stored, and a good damping effect is achieved.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a multifunctional sensor teaching and fixing device. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements. The characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systemization, and networking. It is the first link to realize automatic detection and automatic control. The existence and development of sensors allow objects to have senses such as touch, taste, and smell, and make objects come alive slowly. [0003] The extensive application of sensors and other intelligent control devices in automobiles makes the structure of au...

AI Technical Summary

Problems solved by technology

[0003] The extensive application of sensors and other intelligent control devices in automobiles makes the structure of automobiles more complicated, and also increases the difficulty of automobile teaching and maintenance.

At present, in the process of sensor experiment teaching, most of the sensors are inserted into the teaching board and then connected with the power cord. This kind of teaching board can only be taught after installation, and cannot be viewed while installing, and cannot be given to students. A clearer understanding increases the difficulty of teachers' work
