Description

Technical Field

[0001] This utility model relates to the field of computer teaching technology, specifically to a wall-mounted retractable computer teaching terminal. Background Technology

[0002] A computer is a modern electronic computing machine used for high-speed calculations. The application of computers in China is becoming increasingly widespread. Since the reform and opening up, the number of computer users in China has continued to rise, and the level of application has continued to improve, especially in the fields of the Internet, communications, and multimedia, where remarkable achievements have been made.

[0003] For example, CN214467323U discloses a computer teaching display screen, including a mounting base and a display screen. The display screen consists of a main screen, a secondary screen, and a frame, with the frame fixedly connected to the main screen and the secondary screen. A partition is provided between the main screen and the secondary screen. A fan is fixedly connected to the top outer wall of the display screen. Multiple heat dissipation vents are provided on both sides of the outer wall of the display screen, and dustproof mesh is provided on the inner wall of the heat dissipation vents. Multiple control buttons are installed on one side of the outer wall of the display screen near the top. Fixing grooves are provided at both ends of one side of the outer wall of the display screen, and connecting brackets are fixedly connected to the inner walls of the two fixing grooves. This design prevents dust from adhering to the surface of the display screen and interfering with the user's vision, facilitates the disassembly and installation of the display screen, improves the convenience of use, and prevents the edge of the display screen from colliding with hard objects due to external forces, thereby preventing wear and tear on the edge of the display screen.

[0004] However, in implementing the relevant technology, the above-mentioned computer teaching display screen has the following problems: it is difficult to install and extend, which makes it impossible to provide space for the use of the interface and heat dissipation behind it; it is also difficult to rotate and tilt, which makes it inconvenient for teachers to display content to students at different angles in the classroom; it is difficult to temporarily adjust the touch screen to a flat position, which makes it inconvenient for group interaction, thus reducing the efficiency of use. Therefore, a wall-mounted extendable computer teaching terminal is proposed.

[0005] This represents a restructuring of the traditional teaching structure and model, aiming to create a more efficient, interactive, and people-oriented future classroom ecosystem through technological means. Wall-mounted installation: directly fixed to the wall or a dedicated column, completely freeing up the podium and floor space, making the classroom layout neater and safer. Utility Model Content

[0006] This utility model proposes a wall-mounted retractable computer teaching terminal, which solves the problems in related technologies, such as difficulty in wall-mounting and retractable adjustment, resulting in insufficient space for the use of rear interfaces and heat dissipation, difficulty in adjusting rotation and tilt angles, inconvenience for teachers to display content to students at different angles in the classroom, difficulty in temporarily adjusting to a flat position for touch, and inconvenience for group interaction, thus reducing the efficiency of use.

[0007] The technical solution of this utility model is as follows: A wall-mounted retractable computer teaching terminal, comprising: a teaching terminal unit;

[0008] A rotating mechanism is located at the rear of the teaching terminal and is used to adjust the horizontal rotation of the teaching terminal.

[0009] A pitch mechanism, located at the rear of the rotating mechanism, is used to adjust the pitch angle of the teaching terminal.

[0010] The telescopic mechanism, located behind the telescopic pitch mechanism, is used to adjust the telescopic reach of the teaching terminal.

[0011] A fixed buffer mechanism is located on the rear side of the telescopic mechanism and is used to fix and buffer the teaching terminal.

[0012] The telescopic mechanism includes a fixed plate, two gears rotatably connected to one side of the fixed plate, the two gears meshing with each other, and a telescopic frame movably connected to the top of the two gears. A motor is fixedly installed on the other side of the fixed plate, and the output end of the motor is fixedly connected to one of the two gears.

[0013] Preferably, the rotating mechanism includes a fixed frame, a motor fixedly installed inside the fixed frame, a turntable fixedly connected to the output end of the motor, a circular slide plate fixedly installed on the top of the fixed frame, and multiple sliders slidably connected inside the circular slide plate, with the tops of the multiple sliders fixedly connected to the bottom of the turntable.

[0014] An L-shaped plate is fixedly installed on the top of the turntable, and one side of the L-shaped plate is fixedly connected to the end of the telescopic frame at the rear of the teaching terminal.

[0015] Preferably, the pitching mechanism includes a U-shaped plate fixedly connected to the telescopic frame, a rotating rod rotatably connected inside the U-shaped plate, and a movable block fixedly installed on the outer wall of the rotating rod, wherein the movable block is fixedly connected to the fixed frame.

[0016] Preferably, one end of the rotating rod is rotatably connected to a gear two through the U-shaped plate, a motor two is fixedly installed on one side of the U-shaped plate, and a gear three is fixedly connected to the output end of the motor two, with the gear three meshing with the gear two.

[0017] Preferably, the fixed buffer mechanism includes a mounting plate, support columns fixedly mounted at the four corners of the front side of the mounting plate, and a sliding plate slidably connected to the four support columns. The sliding plate is fixedly connected to the fixed plate.

[0018] Preferably, each of the four support columns is fitted with two springs, the two springs are located on both sides of the slide plate, and the two ends of the springs are fixedly connected to the slide plate and the mounting plate, respectively.

[0019] A damper is fixedly installed between the sliding plate and the mounting plate, and mounting ears are fixedly installed at the four corners of the mounting plate.

[0020] The working principle and beneficial effects of this utility model are as follows:

[0021] A motor drives one gear to rotate clockwise, which in turn rotates another gear, causing the telescopic frame to extend forward via a hinge. This allows the teaching terminal to extend approximately 40-60cm beyond the wall, providing access to the interface on the back.

[0022] The system provides space for heat dissipation. Motor 1 drives the turntable to rotate, which in turn drives multiple sliders to rotate together inside the circular slide plate. This allows the teaching terminal to rotate 180°, making it convenient for teachers to display content to students at different angles in the classroom. Motor 2 drives gear 3 to rotate, which in turn drives the rotating rod to rotate on the U-shaped plate. This allows the movable block to hinge inside the U-shaped plate, which is used to adjust the tilt angle of the teaching terminal from -5° to 90° for teaching. In the vertical state, it can be used for teaching. In the 90° flat state, it can be transformed into a temporary "touch table" to facilitate group interaction, thereby improving the efficiency of use. Attached Figure Description
