[0002] Experimental teaching aids refer to various auxiliary tools and teaching materials used in the teaching process, especially in experimental teaching, which are designed to help teachers better implement teaching and promote students' learning and understanding. Experimental teaching aids can be physical objects, visual materials, auditory materials, electronic equipment, etc., and are widely used in physics, chemistry, biology and other disciplines.

[0008] The insulating support plate is provided with two symmetrically arranged transverse grooves and a plurality of vertical grooves which are arranged to pass through the transverse grooves. The bottom of the power supply, the switch and the lamp holder are all rotatably mounted with a support seat. The bottom of the support seat is provided with an elastic cavity. Two elastic rods are arranged oppositely in the elastic cavity and penetrate the outer wall of the support seat. The outer walls of the two elastic rods are provided with L-shaped blocks which penetrate the elastic cavity downward. A spring which is adapted to the elastic cavity is sleeved between the two blocks on the two elastic rods. In this way, when conducting a series-parallel experiment, according to the teaching knowledge guidance, the power supply, the switch and the lamp holder are placed at the transverse groove and the vertical groove positions required for the experiment, and then the two elastic rods are pushed in opposite directions. The two elastic rods squeeze the springs through the side walls of the blocks, so that the springs shrink in the elastic cavity, thereby clamping the blocks on the support seat into the transverse grooves and the vertical grooves to complete the fixation. Since the arrangement of the transverse grooves and the vertical grooves is modeled on the common series-parallel electrical teaching diagrams in textbook knowledge, it can enable students to intuitively understand and combine textbook knowledge to conduct in-depth learning of the series-parallel electrical course, effectively improving teaching and operability.

[0009] Preferably, in order to fix the block, the inner side walls of the horizontal groove and the vertical groove are provided with anti-slip grooves adapted to the block, thereby ensuring the experimental display effect and being safer and more stable.

[0010] Preferably, in order to install the wires, the power supply, the switch and the bottom of the lamp holder are all provided with a T-shaped rotating hole, and a rotating rod adapted to the rotating hole is fixedly mounted on the support seat, so as to facilitate the connection of the wires.

It is convenient to display according to needs and the operation is convenient and fast.

[0012] Preferably, in order to move the equipment, self-locking universal wheels are fixedly installed on the table legs, so that the operating table drives the equipment on the serial-parallel operation mechanism to move and lock on the ground, which is convenient for display anywhere.

[0013] Preferably, in order to store the device, a storage box for storing power supply, wires, switches, light bulbs and lamp holders is fixedly mounted on the outer side wall of the table, so as to facilitate storage and access of the device.

[0014] Preferably, in order to understand the voltage and current information, the operating device also includes a voltage and current display mechanism, which includes a controller fixedly installed in the table and a voltage sensor and a current sensor fixedly installed in the power supply, switch and lamp holder and electrically connected, a signal transmitting module electrically connected to the voltage sensor and the current sensor is fixedly installed in the power supply, switch and lamp holder, an information storage unit and a signal receiving module adapted to the signal transmitting module are integrated on the controller, and a display screen electrically connected to the controller is fixedly installed on the table. This allows students to intuitively understand the relationship between current and voltage when the different line connection methods are reflected on various electrical experimental equipment in the series and parallel experiments, further improving the teaching quality.

[0015] Preferably, in order to deepen the learning impression, a sound-speaking hole is opened on the table top, and a speaker electrically connected to the controller is fixedly installed in the sound-speaking hole to enhance the dissemination of teaching information.

[0016] When conducting a series-parallel experiment, the operating device places the power supply, switch, and lamp holder at the positions of the horizontal groove and the vertical groove required for the experiment according to the teaching knowledge guidance, and then pushes the two spring rods in opposite directions. The two spring rods squeeze the spring through the side wall of the card block, so that the spring contracts in the spring cavity, thereby clamping the card block on the support seat into the horizontal groove and the vertical groove to complete the fixation. Since the arrangement of the horizontal groove and the vertical groove imitates the common series-parallel electrical teaching diagrams in textbook knowledge, it can enable students to intuitively understand and combine textbook knowledge to conduct in-depth learning of the series-parallel electrical course, effectively improving teaching and operability.

[0017] When conducting a series-parallel experiment, the operating device connects the power supply, the switch and the light bulb on the lamp holder through wires. Whenever one of the power supply, the switch and the light bulb on the lamp holder is energized, the voltage sensor and the current sensor can transmit the current and voltage information of the power supply, the switch and the light bulb to the controller through the signal transmitting module. The controller receives the current and voltage information of each electrical experimental apparatus through the signal receiving module and transmits it to the information storage unit for storage. The current and voltage information is then processed by the controller and displayed on the display screen, so that students can intuitively understand the relationship between current and voltage when different line connection methods are reflected on each electrical experimental apparatus in the series-parallel experiment, thereby further improving the teaching quality.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Example 1

[0027] This embodiment provides an intelligent integrated physical experiment operation device, such as Figure 1-5 As shown, the operating device includes an operating table 1 and a serial-parallel operating mechanism 2 installed on the operating table 1:

[0028] The series-parallel practical operation mechanism 2 comprises an insulating support plate 21 rotatably mounted on the operating table 1, a power supply 22 for performing series-parallel electrical experiments, a wire 23, a switch 24, a bulb 25, and a lamp holder 26 for mounting the bulb 25;

[0029] The insulating support plate 21 is provided with two symmetrically arranged transverse grooves 27 and a plurality of vertical grooves 28 which are arranged to pass through the transverse grooves 27. The power supply 22, the switch 24 and the lamp holder 26 are all rotatably mounted with a support seat 29 at the bottom. A spring cavity 210 is provided at the bottom of the support seat 29. Two spring rods 211 which penetrate the outer wall of the support seat 29 are arranged opposite to each other in the spring cavity 210. On the outer side walls of the two spring rods 211, there are oppositely arranged L-shaped blocks 212 which penetrate downwardly through the spring cavity 210. A spring 213 which is adapted to the spring cavity 210 is sleeved between the two blocks 212 on the two spring rods 211.

[0030] During use, when conducting a series-parallel experiment, according to the teaching knowledge guidance, the power supply 22, the switch 24, and the lamp holder 26 are placed in the positions of the horizontal groove 27 and the vertical groove 28 required for the experiment, and then the two spring rods 211 are pushed in opposite directions. The two spring rods 211 squeeze the spring 213 through the side wall of the block 212, so that the spring 213 contracts in the spring cavity 210, thereby inserting the block 212 on the support seat 29 into the horizontal groove 27 and the vertical groove 28 to complete the fixation. Since the arrangement of the horizontal groove 27 and the vertical groove 28 imitates the common series-parallel electrical teaching diagrams in textbook knowledge, it can enable students to intuitively understand and combine textbook knowledge to conduct in-depth study of the series-parallel electrical courses, effectively improving teaching and operability.

[0031] Specifically, the inner side walls of the horizontal groove 27 and the vertical groove 28 are provided with anti-slip grooves 214 adapted to the clamping block 212. When in use, after the clamping block 212 is inserted into the horizontal groove 27 and the vertical groove 28, it is slidably connected with the anti-slip groove 214, thereby ensuring that the power supply 22, the switch 24, and the lamp holder 26 will not be separated from the insulating support plate 21, ensuring the experimental display effect, and being safer and more stable.

[0032] More specifically, the bottom of the power supply 22, the switch 24 and the lamp holder 26 are all provided with a T-shaped rotating hole 215, and a rotating rod 216 adapted to the rotating hole 215 is fixedly mounted on the support seat 29. When in use, when the power supply 22, the switch 24 and the lamp holder 26 are connected through the wire 23, due to the turning of the horizontal groove 27 and the vertical groove 28, the angle of the power supply 22, the switch 24 and the lamp holder 26 on the support seat 29 can be adjusted by rotating the power supply 22, the switch 24 and the lamp holder 26, so as to facilitate the connection of the wire 23.

[0033] Furthermore, the operating table 1 includes a table top 11 and a table leg 12 fixedly mounted at the bottom of the table top 11. A sunken groove 13 matching the insulating support plate 21 is provided on the table top 11. The insulating support plate 21 is hinged to one end of the sunken groove 13. Two sections of support bars 14 are hinged to the outer wall of the table top 11 and are connected end to end. The connection parts of the support bars 14 are all screwed with tightening knobs 15. When in use, loosen the tightening knob 15 so that the support bar 14 can rotate along the connection point, and then rotate the insulating support plate 21 along the hinge part of the insulating support plate 21 and the sunken groove 13. After rotating to a suitable height, tighten the tightening knob 15 to fix the insulating support plate 21 at a specific display angle, which is convenient for display according to needs, and the operation is convenient and quick.

[0034] Furthermore, self-locking universal wheels 16 are fixedly mounted on the table legs 12. When in use, the table top 11 is pushed, so that the operating table 1 drives each device on the serial-parallel practical operation mechanism 2 to move and lock on the ground, which is convenient for display anywhere.

[0035] Among them, a storage box 217 for storing a power source 22, a wire 23, a switch 24, a bulb 25 and a lamp holder 26 is fixedly installed on the outer wall of the table top 11. When in use, the power source 22, the wire 23, the switch 24, the bulb 25 and the lamp holder 26 are all placed in the storage box 217 for storage and use.

[0036] Example 2

[0037] Different from Example 1, in the series-parallel practical experiment teaching, the current and voltage relationship existing in the series-parallel electrical experiment is also an indispensable part of teaching. For this reason, the operating device also includes a voltage and current display mechanism 3, which includes a controller 31 fixedly installed in the table top 11 and a voltage sensor 32 and a current sensor 33 fixedly installed in the power supply 22, the switch 24 and the lamp holder 26 and electrically connected. A signal transmitting module 34 electrically connected to the voltage sensor 32 and the current sensor 33 is fixedly installed in the power supply 22, the switch 24 and the lamp holder 26. An information storage unit 35 and a signal receiving module 36 adapted to the signal transmitting module 34 are integrated on the controller 31, and a display screen 37 electrically connected to the controller 31 is fixedly installed on the table top 11.

[0038] During use, when conducting series-parallel experiments, the power supply 22, the switch 24 and the bulb 25 on the lamp holder 26 are connected through the wire 23. Whenever one of the power supply 22, the switch 24 and the bulb 25 on the lamp holder 26 is energized, the voltage sensor 32 and the current sensor 33 can transmit the current and voltage information of the power supply 22, the switch 24 and the bulb 25 to the controller 31 through the signal transmitting module 34. The controller 31 receives the current and voltage information of each electrical experimental apparatus through the signal receiving module 36, and transmits it to the information storage unit 35 for storage. Subsequently, the current and voltage information is processed by the controller 31 and displayed on the display screen 37, so that students can intuitively understand the relationship between current and voltage when the different line connection methods are reflected on each electrical experimental apparatus in the series-parallel experiment, thereby further improving the teaching quality.

[0039] Specifically, a speaker hole 38 is provided on the table 11, and a speaker 39 electrically connected to the controller 31 is fixedly installed in the speaker hole 38. When the current and voltage information are recorded through the display screen 37, the controller 31 can control the speaker 39 to broadcast the data information from the speaker hole 38 to enhance the dissemination of teaching information.

[0040] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
