Embodiment 1

[0011] Such as figure 1 A wall chart device in the middle wheel, mainly composed of a center wheel 1, a steering wheel 2, a fixed seat 3, and a draw rope 4. It also includes a hanging plate 5 installed at one end of the draw rope 4, and a clip installed on one side of the hanging plate 5 6;

[0012] The clips 6 are a pair.

[0013] The wall chart device provided by the present invention adopts the above-mentioned structure. When in use, the teaching chart is clamped by the clip 6. If the teaching chart is large, a pair of clips can be used, and then the pull rope 4 can be pulled to achieve After the required position, the pull rope 4 can be fixed on the fixing seat 3. If the teaching diagram is put down, the pull rope 4 can be unfastened from the fixing seat 3.

Abstract

The invention belongs to the field of teaching appliances and relates to a picture hanging device to achieve the purpose of ensuring that various teaching pictures can be conveniently hung. According to the technical scheme, the picture hanging device is mainly composed of a central wheel, a steering wheel, a fixing seat and a pull rope, and further comprises a hanging plate installed at one end of the pull rope, and a pair of clamps are installed on one side of the hanging plate. When the picture hanging device is used, a teaching picture is clamped by one clamp, and the pair of clamps are used if the teaching picture is large; then the pull rope is pulled to enable the teaching picture to reach a needed position, and then the pull rope is fixed to the fixing seat. If the teaching picture needs to be put down, the pull rope simply needs to be untied from the fixing seat. The device is scientific, reasonable and simple in structural design, good in use effect and high in popularization value.
