Description

Portable multi-functional teaching display device

Technical Field

The invention relates to a teaching display device.

Background

First, teaching board status quo

The teaching board which is large in area and convenient to carry is often needed in the mobile or outdoor teaching activities, the board area of the teaching board is usually greatly reduced, but the writing area is limited in the teaching activities; although the non-foldable large-area teaching board can meet the writing area, the board is inconvenient to carry and transport; although the foldable large-area teaching board is convenient to carry and transport, the foldable large-area teaching board depends on facilities of a teaching field, the foldable part of the board surface cannot be fixed after being unfolded, the foldable large-area teaching board needs to be hung and used by depending on a building vertical surface with the same area and stability, and the field is not flexible to use; in addition, the bracket for supporting the teaching board is usually combined by adopting a single tubular material, and the bracket is light in weight, not only easy to damage, but also easy to topple over when encountering wind; teaching boards are not used or when moving, the support is dismantled complicatedly, and inconvenient accomodating, teaching aids such as the chalk that matches, blackboard eraser, ruler are dispersed and are placed, easily lose the damage.

Second, publicizing the present situation of the display board

The electronic display frequency of the propaganda display board is a necessary device for enterprises, merchants and the like to conduct activities such as propaganda marketing, image display, brand promotion, product recommendation and the like, the commonly used propaganda display board with a large area is a non-detachable structure, a pipe is directly used as a frame, the display board is installed, and the propaganda display board has the defects of inconvenient carrying and moving and space occupation when not used; one is a foldable and portable structure, but has poor stability, weak wind resistance and complex disassembly and assembly when used outdoors; the utility model discloses a take advantage of the stand that sets up, adopt truss or other tubular product to build, though carry the transportation convenience, the equipment is complicated, consumes manpower and materials, above-mentioned several kinds prevent empting for anti-wind when using in the open air, adopts pressurization sand bag or other counter weight materials mostly to strengthen its steadiness, but the counter weight thing is mostly exposed outside, and the influence is pleasing to the eye, and propaganda show function is single.

For solving above-mentioned technical problem, CN207233348U discloses a portable multi-functional collapsible teaching display device, wherein the last hinge of frame crossbeam has the spliced pole, the spliced pole lower extreme suit is in the telescopic link in the telescopic bracket, the last hinge of telescopic bracket has the support couple, support couple front end and frame articulate, the bottom of telescopic bracket articulates with the base of assembling in the containing box, the containing box sets up two upper covers, one of them upper cover and the corresponding department of telescopic bracket set up the breach that has the positioning action to the telescopic bracket. This kind of teaching display device can make teaching show board and flexible folding support accomodate in the containing box completely after folding, has realized by bulky, irregular to little volume, modular folding conversion, has satisfied the teaching activity and has write by a large scale and publicize the basic demand of show activity. But because telescopic bracket sets up in the middle part of containing box, and the containing box upper cover has to set up corresponding breach with it, this kind of unreasonable project organization causes the containing box case lid intensity of seting up the breach to descend simultaneously, yielding damage, teaching show board steadiness is not high, in addition because the support is suit telescopic structure, there is great flexible clearance, and telescopic bracket only case lid and support top suit propaganda show board's spliced pole as horizontal support, lead to hanging behind the dress teaching show board, whole range of rocking is great, stability and wind resistance when having reduced the outdoor use, telescopic structure makes the teaching show board be single fixed orientation simultaneously, be not convenient for installation and specific occasion use.

Disclosure of Invention
