Description

Hand-clamping-prevention paperless conference terminal

Technical Field

The utility model relates to a conference system technical field especially relates to a prevent paperless conference terminal of tong.

Background

The paperless conference was originally proposed by the non-government organization committee of the united nations in 2003, which is one of the means for trying to improve the working efficiency and working method of the committee by operating the non-government organization committee in a full electronic mode; compared with the traditional conference structure, the use of a large amount of disposable materials such as paper, plastics and the like not only causes resource waste, but also makes the conference preparation work more complicated and time-consuming due to the use of excessive solid materials; the paperless conference system is an intelligent conference interaction system based on a local area network, a private network or a mobile internet, and realizes paperless conference by electronic exchange of files by applying a communication technology, an audio technology, a video technology and a software technology, and is characterized in that: the intelligent conference system has the advantages of networked file transmission, electronic file display, intelligent file editing and controllable file input and output, and is more efficient in conference efficiency and more environment-friendly in resource use, and the paperless conference is also more attractive and concise.

When a traditional conference is in a meeting, a large number of paper files are needed, and when the number of participants is large, the paper files with the large number are prepared, so that time and labor are wasted, the conference efficiency is influenced, resources are wasted, and the method is contradictory to the current requirement of environmental protection and greening of the society; part of the conferences are improved, a projector is used for being matched with a large screen to share files, and even in the case of a small conference place, part of people cannot obtain a good view due to the angle problem; therefore, at present, paperless conferences tend to install independent displays on each desktop, and each participant can synchronously watch the conference content through the screen in front under the control of a conference host computer, and furthermore, the used displays are mostly touch screens, so that each conference unit can not only receive data signals of the conference host computer, but also integrate conference functions on an intelligent display terminal to the greatest extent by taking a liquid crystal touch display terminal as a center, thereby forming an 'people-oriented' intelligent conference experience and providing the most natural human-computer interaction interface and the optimal use experience for users; the most common paperless conference system in the market today can be divided into a table top type, a turnover type, a flat plate type and a lifting type, wherein the table top type cannot hide a screen when the screen is not needed, the appearance is influenced, the size of the flat plate type is limited, the integrated conference unit module is also limited, the turnover type can damage the screen when the desktop is accidentally pressed, the opening is large, the appearance is influenced, and therefore the lifting type paperless conference unit is the optimal choice at present.

Patent application No. CN201820070577.3 provides a conference table with LCD screen raising and lowering functions, including the conference table body, inlay on the desktop of conference table body and be provided with the case, lead screw through the fixed setting on the motor output shaft in the case, when making the motor rotatory, slider on the drive lead screw rises or descends, and then the LCD screen in the drive case accomplishes the work that rises and descends, the raising and lowering functions of display screen has been accomplished through motor drive lead screw structure to this scheme, but be used for perpendicular driven ordinary trapezoidal screw mechanism on the one hand manufacturing cost is higher, on the other hand, ordinary trapezoidal screw mechanism transmission efficiency is underneath, when frequently coming and going to use, the return stroke precision is poor, the transmission clearance is big, influence user experience.
