Utility model content

The purpose of the utility model is to provide a multimedia teaching device for information technology courses that is convenient, easy to carry, and takes up less space to address the shortcomings of the existing technology.

The purpose of this utility model is to provide a multimedia teaching device for information technology courses, which includes an upper base plate, a lower base plate and an “X”-shaped connector; the lower base plate is provided with a track, and the A slider is provided in the track; the upper end of the "X"-shaped connector is fixed on the upper base plate, and the lower end is fixed on the slider; the upper base plate is also provided with a supporting plate, and the supporting plate is hinged with a curtain plate. A curtain is arranged on the curtain plate, and a groove is arranged in the middle of the supporting plate, and a telescopic rod is arranged in the groove, and a projector is hinged to the head of the telescopic rod.

Preferably, top blocks are further provided on the upper and lower bottom plates, and springs are also provided between the top blocks of the upper and lower bottom plates. The springs provided on the upper and lower base plates of the utility model can ensure the stability of the upper and lower base plates during use, and buffer the destructive force of accidents.

Preferably, the upper and lower bottom plates are further provided with matching blocks and slots. The card slot and the card block can be used in conjunction, and the utility model can be closed as a box when not in use, and the card slot block puts the whole device together, making it easier to carry.

Preferably, there are two sets of the "X"-shaped connectors. Setting two sets of "X" shaped connectors increases the stability of the overall structure.

Beneficial effects: the utility model has a simple structure and is easy to use. The "X"-shaped connector can adjust the height of the upper and lower base plates and can combine the upper and lower base plates together to reduce the occupied space and volume. A projector is installed in the support plate to connect Other multimedia equipment can be used in conjunction with the curtain on the curtain board for teaching, and the curtain board and the supporting board are hinged and can be covered on the supporting board, and the projector can also be placed in the groove under the action of the telescopic rod. The structure of the whole machine is small and exquisite. Simple and practical, it is very easy to carry after merging, and it is convenient for teachers to teach.
