Embodiment Construction
[0017] Such as figure 1 with figure 2 As shown, an electrical experiment box provided by the present invention is characterized in that it includes a box body 1, which is composed of an instrument box 1a, a tool box 1b and a glove box 1c, which is an open structure. The adjustable transformer 4, the power supply 5 and the automatic winding reel 6 are respectively connected inside the instrument box 1a. The adjustable transformer 4, the power supply 5 and the automatic winding reel 6 are all connected on the side wall by screws, and the adjustment button 4a of the voltage regulating transformer 4, the switch 5a of the power supply 5 and the automatic winding reel are also provided at the corresponding positions on the side wall. The button 6a of the wire reel. After winding the power cord 7 on the button 6a of the automatic reel, it is connected on the adjustable transformer 4 and the power supply 5, and the power cord 7 runs through the side wall of the box body 1 and leads...

The invention relates to an electrics experimental box which is characterized by comprising a box body (1). The box body (1) is composed of a meter box (1a), a tool box (1b) and a clutter box (1c) and in a structure with an opening opened. An adjustable transformer (4), a power source (5) and an automatic wire spool (6) are arranged in the meter box (1a). A rear box cover (2) is connected with the box body (1). A testing board installation groove (2c) is formed in the box cover (2). A universal testing board (3) is connected in the testing board installation groove (2c) in a matched mode. A set of an ammeter and a loudspeaker (12) are arranged in the testing board installation groove (2c). The electrics experimental box has the advantages of being simple in structure, novel in design and capable of containing various electrics experimental devices. Due to arrangement of different containing boxes, articles can be placed in classification, so that the phenomenon that the various devices are placed disorderly is avoided. Due to arrangement of common used meters inside, usage in an experiment is convenient.
Description
technical field [0001] The invention relates to a physics teaching experiment device, in particular to an electrical experiment box for physics teaching. Background technique [0002] In physics teaching, electrical experiments are often done for demonstration. Most of the current experimental equipment is scattered, and there are many equipments that need to be carried when doing experiments. Often due to negligence, the experiments cannot be carried out as scheduled, which brings great difficulties to the experiment. It is inconvenient, and the storage of existing power cords is troublesome. After extensive searching, no relevant technical solutions have been found yet. Contents of the invention [0003] The purpose of the present invention is to solve the disadvantages such as scattered physical experiment equipment at the present stage, which brings inconvenience to the experiment, and proposes an electrical experiment box. [0004] In order to achieve the above obje...
