TECHNICAL FIELD

[0001] The utility model relates to the technical field of educational equipment, more particularly to an educational demonstration device. BACKGROUND

[0002] In the current educational environment, physical experiments, chemical experiments, and biological experiments, etc. are indispensable teaching links. These experiments not only help students to understand theoretical knowledge in depth, but also cultivate their practical ability and scientific spirit. However, in the traditional experimental teaching mode, students often need to gather near the podium so that they can clearly observe the experimental equipment, the experimental process, and the experimental phenomena. This gathering type of viewing not only limits the students' learning space, but also may affect the students' learning effect due to limited vision or insufficient light, etc.

[0003] Based on the above problems, we provide an educational demonstration device. UTILITY MODEL CONTENT

[0007] Preferably, the shooting assembly comprises a camera rotatably assembled on the side of the L-shaped plate.

[0008] Preferably, the side end of the camera is equipped with an LED lamp.

[0009] Preferably, the side end of the camera is equipped with a microphone.

[0010] Preferably, a gear is arranged on the rotating shaft of the camera, a movable rod is slidably connected to the side of the L-shaped plate through a cushion block, a conical block is fixedly connected to the side end of the movable rod, the conical block is arranged in the gear slot of the gear, a cushion disc is fixedly connected to the middle part of the movable rod, and a spring is arranged between the movable rod and the cushion block.

[0011] Preferably, the lifting piece is an electric push rod.

[0012] Preferably, the crossbar is rotatably mounted at the output end of the electric push rod via a rotating sleeve.

[0013] Preferably, the bottom of the base is fitted with a magnet.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] 1. By placing the base on the podium, the teacher can adjust the position, height, and angle of the camera component according to the placement of the equipment for physics (chemistry, biology, etc.) experiments, so that the camera component can be aimed at the equipment. Then, the camera component is connected to the display screen in the blackboard, so that the experimental process and experimental phenomena can be transmitted to the display screen for students to watch. Through this structural design, students in the classroom can easily watch physics experiments, thus eliminating the need for students to gather near the podium to watch.

[0016] 2. When the camera is rotated, the gear on the camera shaft will rotate, thereby pushing the conical block to move. The moving rod will drive the spring to contract, which has elastic potential energy. When the conical block is aligned with another tooth groove of the gear, the spring will extend, so that the conical block is placed in the tooth groove of the gear again. Through this structural design, the stability of the camera's position after rotation can be guaranteed.
