Low-noise lifting electronic screen

Abstract

The invention discloses a low-noise lifting electronic screen which comprises a protection device, a lifting device and a control switch. The Low-noise lifting electronic screen is characterized in that the protection device comprises a shell, a first control circuit board, a second control circuit board, a pulley cover, a data access port and a power supply connector, the shell further comprisesa pulley cover, a first pulley, a second pulley and a third pulley, a lifting device is arranged in the shell, the lifting device comprises an electronic screen body, a lifting table, slide rods, sliders, a supporting frame and a motor, the slide rods are arranged on the left side and the right side of the inner surface of the shell respectively, the sliders sleeve the surfaces of the slide rods,the top end of the lifting table is electrically connected with the electronic screen body, the lifting table comprises a fixed base and a fourth pulley, and a control switch is arranged at the top end of the shell. A rope is wound through a driving motor, and therefore the lifting table is driven to stably rise or fall; no noise is produced in the lifting process, and the low-noise comfortable working environment is created.

Description

Technical field [0001] The invention relates to the field of electronic screens, in particular to a low-noise lifting electronic screen. Background technique [0002] Simply speaking, the electronic screen is composed of several display units (unit display boards or unit display boxes) that can be combined and spliced ​​to form the screen body, plus a set of appropriate controllers (main control boards or control systems). Therefore, a variety of display boards (or unit boxes) with different control technology controllers can form many kinds of LED displays to meet the needs of different environments and different display requirements. [0003] With the continuous popularization of electronic screens, electronic screens are also used in some speech activities to provide text assistance to speakers. However, existing electronic screens are fixed on the podium. When electronic screens are not needed for assistance and use, The whole machine needs to be dismantled, which not only red...

Problems solved by technology

[0003] With the continuous popularization of electronic screens, electronic screens are also used in some speech activities to provide text assistance for speakers. However, the existing electronic screens are fixed on the podium. When the electronic screen is not needed for assistance and use, it is The whole machine needs to be dismantled, which not only reduces the use space of the podium, but also requires too much labor to operate the whole machine during the disassembly process. Therefore, a low-noise lifting electronic screen is proposed
