Projection device for computer education and teaching

Abstract

The invention discloses a projection device for computer education and teaching. The projection device comprises a projection machine body, wherein the lower surface of the inner portion of the projection machine body is provided with a high-definition projection head, the high-definition projection head is fixedly connected with the projection machine body, a heat dissipation box is located at the bottom end of the projection machine body and fixedly connected with the projection machine body, and the upper surface of the inner portion of the heat dissipation box is provided with a heat dissipation fan. The projection device for computer education and teaching has the advantages that in a storage state, a user can rotate a second telescopic bracket to a gap between two first telescopic brackets, a bottom plate is in lap joint with the upper surfaces of the first telescopic brackets, so that space is reduced and the appearance is not affected. If the height of a projector needs to be adjusted, the second telescopic bracket can be unfolded through a rotating shaft, a cardan shaft drives the first telescopic brackets to rotate, thereby being capable of adjusting the height of the projector, the projection device can be fixed conveniently through the bottom plate to prevent toppling, the projection device can be placed on an appropriate position of a classroom according to practical situations, the height adjustment is convenient, the placement is stable, and carrying is convenient.

Description

technical field [0001] The invention belongs to the technical field of projection equipment, and in particular relates to a projection device for computer education and teaching.
