Description

A new type of projector frame used in art design teaching

technical field

The utility model relates to the technical field of projector racks, in particular to a novel projector rack used in art design teaching.

Background technique

In the long-term teaching practice, the projector is either placed on the table or hung on the ceiling. The single method of use cannot meet the use in modern teaching classrooms. When adjusting the angle of the projector, the angle or height of the projector itself is limited. The best angle is often not adjusted. Students cannot clear and watch the projector image, and most of the projector racks cannot be adjusted in height and angle during use, or the adjustment method is more complicated, which makes it difficult for users to teach during the teaching process. Good, which in turn makes the students' acceptance level not high, resulting in a series of consequences.

Preferably, the fixing plate is installed on the wall through a fixing piece.

Preferably, the telescopic structure is composed of a sleeve and a support rod, and the support rod is inserted into the sleeve, and the locking device is located on the sleeve.

Preferably, the bracket and the placement board are integrally formed.

In the utility model, when the user uses the device, the projection device can be placed on the placement board, and the projection device can be made more stable through the bracket, and the telescopic structure can be extended or shortened by the locking device to realize the height of the entire device. Adjustment, when the projection angle effect is not good, you can turn the connecting plate to a suitable position with the rotating shaft as the axis, and then close the fixing device, and then realize the angle adjustment of the whole device. The device is easy to operate, and the telescopic structure makes the projection The height of the projection can be adjusted, and the fixing device and the rotating shaft can make corresponding adjustments in the angle of the projection to achieve two-way adjustment of height and angle to meet the needs of users and achieve efficient and fast adjustment.
