Detailed Description

In order to make the technical problems, technical solutions and technical effects achieved by the present invention more clear, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

In the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "fixed" are to be understood broadly, e.g. as a fixed connection, a detachable connection or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. "beneath," "under" and "beneath" a first feature includes the first feature being directly beneath and obliquely beneath the second feature, or simply indicating that the first feature is at a lesser elevation than the second feature.

In the correlation technique, some combination screens and wisdom blackboard, including the polylith screen body, install the location through location structure earlier between the screen body, rethread adaptor and screw are fixed with two screen bodies lock to realize assembling between the screen body and connect. However, such a combined screen is inefficient to assemble.

In the related art, some combined screens and intelligent blackboards include a main screen body and auxiliary screen bodies arranged on the left and right sides of the main screen body, the auxiliary screen body arranged on the left side of the main screen body is a left auxiliary screen body, and the auxiliary screen body arranged on the right side of the main screen body is a right auxiliary screen body. And the right side of the left auxiliary screen body and the left side of the right auxiliary screen body are respectively provided with a connecting structure so as to install the auxiliary screen body to the main screen body. During assembly, due to the limitation of a connection structure between the auxiliary screen body and the main screen body, if the right auxiliary screen body is mistakenly turned over by 180 degrees and arranged on the left side of the main screen body in a vertically-turned manner, the installation of the auxiliary screen body cannot be completed. That is, the left and right sub-screens of the intelligent blackboard in the related art cannot be used in a mixed manner. So, the material variety that leads to combination screen and wisdom blackboard is many, the wrong vice screen body's of dress problem when appearing the packing easily.

Based on this, this application provides a combination screen, still provides an wisdom blackboard. Connection structure between the screen body has been optimized to combination screen and wisdom blackboard, realizes assembling the connection through the mode that articulates between the screen body, need not to use the screw lock to attach, and the equipment of being convenient for, the packaging efficiency is high. And the same screen body can be used as the left auxiliary screen body and the right auxiliary screen body, so that the material types of the combined screen can be reduced, the problem of wrong material loading during packaging of the combined screen can be avoided, and the packaging is more convenient.
