Abstract

The invention discloses carrying-facilitating projection equipment comprising a miniature projector, a display screen and a flat mirror. The miniature projector comprises a miniature projector body and a base, wherein the base is "<"-shaped and the inclined angle of the horizontal segment of the base and the inclination segment of the base is an acute angle. The miniature projector body is arranged at the internal side of the base. The display screen is fixed on the inclination segment of the base. The top part of the flat mirror is hinged on the upper end of the display screen. The front surface of the flat mirror is a mirror surface. The upper end of the display screen is provided with a downwardly inclined slope. The problems in the prior art that space required for installation of a split type projection display assembly is large and installation is difficult, carrying is inconvenient and use occasions are limited can be overcome.

Description

technical field [0001] The invention relates to a projection device, in particular to a portable projection device. Background technique [0002] In the field of graphics and image magnification display technology, projectors undoubtedly occupy a pivotal position. The projector and its display structure in the prior art are all independent and separated, that is, the display screen and the projector are two independent instruments, and a relatively large space is required to accommodate the display screen and the projector during installation and use, and the installation is also difficult. More labor-intensive and time-consuming. In today's society where efficiency is increasingly pursued, this projection display structure is powerless for some small-scale communication activities or other similar communication activities. Therefore, there is an urgent need for a projection display assembly that is easy to carry, simple in structure, small in size and capable of meeting c...
