Projection device for elevator room and use method of projection device

Abstract

The invention discloses a projection device for an elevator room and a use method of the projection device. The projection device comprises a device shell, wherein a heat dissipating panel is fixedlyconnected to the outer surface of the front end of the device shell, a projection lens is fixedly connected to the outer surface of the upper end of the device shell, a sliding baffle plate is movablyconnected at the position, behind the projection lens, of the outer surface of the upper end of the device shell, a connecting block is fixedly connected to the outer surface of one side of the device shell, a fixing bracket is arranged on one side below the connecting block, and a sliding track and an infrared sensing lamp are fixedly connected to the outer surface of one side of the device shell. For the projection device for the elevator room and the use method of the projection device provided by the invention, a rotation shaft, the infrared sensing lamp and the sliding baffle plate are arranged, the projection direction of the projection device can be adjusted, meanwhile, the projection device is automatically closed when no people are in the elevator room, thus energy is saved, in addition, dust on the surface of the projection lens can be resisted, so that the projection effect of the projection device is good, and good use prospect is brought.

Description

technical field [0001] The invention relates to the field of projection equipment, in particular to a projection equipment in an elevator room and a method for using it. Background technique [0002] Projection equipment is an optical instrument that uses optical elements to enlarge the outline of a workpiece and projects it onto a video screen. With the development of society, people give full play to the functions of projection equipment and use projection equipment in all aspects of life. Among them, there is projection equipment in elevator rooms. With the continuous development of science and technology, people's requirements for projection equipment are getting higher and higher. Existing projection equipment can no longer meet people's needs; Disadvantages, firstly, it is inconvenient for people to adjust the angle of the projection device, which greatly reduces the practicability of the projection device; secondly, the existing projection device continues to project ...

[0002] Projection equipment is an optical instrument that uses optical elements to enlarge the outline of a workpiece and projects it onto a video screen. With the development of society, people give full play to the functions of projection equipment and use projection equipment in all aspects of life. Among them, there is projection equipment in elevator rooms. With the continuous development of science and technology, people's requirements for projection equipment are getting higher and higher. Existing projection equipment can no longer meet people's needs; Disadvantages, firstly, it is inconvenient for people to adjust the angle of the projection device, which greatly reduces the practicability of the projection device; secondly, the existing projection device continues to project when the elevator stops, which consumes more energy; There is dust on the lens, which will affect the effect of projection and bring a certain impact on people's use process. Therefore, we propose an elevator projection equipment and its use method
