Abstract

A digital media display and projection device that is convenient for adjusting the inclination angle, including a box with an open top surface, two sides of the top surface of the box are respectively hinged with switch doors through torsion springs, and a cylinder with an open bottom is arranged in the box. The body runs through the bottom of the box and is fixedly connected with it. The two sides of the front of the inner wall of the box are respectively connected to the front end of the first rotating shaft. One of the first rotating shafts runs through the front of the box. There is a pressure regulating device in the box. Equipped with angle adjustment device. This device fixes the device by pumping air to cause air pressure difference. This fixing method does not require operations such as drilling, and will not cause damage to the placement surface. Secondly, the installation and adjustment of the device are simple. By rotating one of the The first rotating shaft can realize the fixing of the device, the height adjustment of the projector and the control of opening and closing the door. Compared with the fixed bracket, the device can suck the placement surface tightly, has better firmness, and can prevent the projector from moving.

Description

technical field [0001] The invention belongs to the field of projection equipment, in particular to a digital media display projection device which is convenient for adjusting the tilt angle. Background technique [0002] Projector equipment manufacturers need to display the functions of the projector at different exhibitions when promoting new products. When manufacturers carry projectors to promote at various exhibitions, they need to fix and adjust the angle of the projector. Projectors are mostly fixed by fixing brackets, but there are many pedestrians in the exhibition, so if the projector moves and deflects, the projected image cannot be aligned with the projection screen, and the manufacturer needs to re-adjust the position of the projector, which is extremely inconvenient to use. Contents of the invention [0003] The invention provides a digital media display projection device which is convenient to adjust the inclination angle, so as to solve the defects in the p...
