Description

Synchronized Door Open Multimedia Podium

technical field

The utility model belongs to the field of teaching equipment, relates to the improvement of the cover structure of a multimedia lectern, and in particular relates to a synchronously door-opening multimedia lectern.

Background technique

Multimedia platform (English: Multimediaplatform) is widely used in school teaching, training and other places. It is a product that integrates the platform with electronic products such as computers, multimedia control systems, video booths, audio equipment, and audio converters.

The multimedia podium completely requires the standard design of the daily podium, and adopts the principle of ergonomics, which meets the needs of teachers' teaching. In addition to the role of a common lectern, it also integrates a computer inside and a monitor on its desktop. Due to the new integrated design, the appearance is neat and beautiful, and it is free from the constraints of various connecting lines behind the PC. Its unique safety and stability make it easy and safe for teachers to operate in the application process.

Most of the multimedia podiums on the market are usually opened or closed manually. If the opening and closing of the door is heavy, it will be more laborious for teachers to open the door, which is more troublesome to use. In addition, the existing multimedia podium lacks identification of users, which is not conducive to management and maintenance.

For example, "an improved multimedia platform for computer education" disclosed in a Chinese patent (authorized publication number CN 209474005 U) includes a table top, the upper surface of which is embedded with a display screen, and the upper surface of the table top is close to the display screen A protective cover is connected by hinge rotation at one side of the countertop, a control box is fixedly installed on one side of the upper surface of the countertop close to the protective cover, a cabinet is fixedly installed on the lower surface of the countertop, and a lower surface of the countertop is fixedly installed with a cabinet. A locker is fixedly installed on one side of the surface close to the cabinet, and a stable base is fixedly connected to the lower surface of the cabinet; through the plane mirror, the number of times teachers look down at the display screen when using the multimedia platform can be reduced, and the use of the multimedia platform by teachers can be improved. The rubber protective pad can greatly reduce the force, so as to protect the display screen; at the same time, the setting of the protective cover can avoid the problem that the display screen is exposed for a long time and easy to accumulate dust.

Another example is "a left and right horizontal push-type multimedia platform" disclosed in the Chinese patent (authorized announcement number 209185880U), which includes a platform body, a turntable is installed inside the groove, and the left push-pull table and the right push-pull table are far away from the outer side of the touch display screen. Fans are installed on both the left push-pull table and the right push-pull table along the axial outer surface of the sliding rail. A number of cooling fins are installed on the top of the rotating shaft. The utility model can easily adjust the angle and height of the microphone on the basis of increasing the area of the workbench, and is convenient for teachers to use. It not only maintains good ventilation and heat dissipation effects for the electrical components inside the platform body, but also prevents a large amount of dust in the air from passing through. The gaps at the heat dissipation fins enter the interior of the left push-pull table and the right push-pull table, which is convenient for teachers to clean the podium.

The above disclosed multimedia platform still has shortcomings, and it is laborious and inconvenient to use when opening the door.
