Abstract

The utility model discloses a novel movable blackboard which relates to an educational affiliation. A first blackboard and a second blackboard are arranged in an upper frame; a third blackboard and a fourth blackboard are arranged in the lower frame; and after wire cable passes through a dead pulley, both ends of the wire cable are respectively connected with the upper frame and the lower frame. The novel movable blackboard provided by the utility model realizes the free movement of each small blackboard in the frames through the combination of a plurality of small blackboards, and students in any part of the classroom can see the contents on the blackboards through moving the novel movable blackboard. In addition, teachers can pull the blackboard at a far place or a high place to an appropriate position or height for writing, so the work intensity of the teachers can be lightened.

Description

The novel movable blackboard

Technical field

The utility model relates to a kind of teaching aid, particularly a kind ofly is made of the novel movable blackboard that each part can move arbitrarily the polylith blackboard in framework.

Background technology

As the student, the number of times that looks at the blackboard many times because the difficulty that looks at the blackboard and run into makes me produce the hope of creating this utility model.The difficulty that I run into mainly is that the classroom is too wide, just cannot see the content on the blackboard other end when sitting on the limit, even at school the time, also unavoidably to stand up sometimes or the shift-in blackboard some, this has brought too many inconvenience to study.Also some teacher gets used to using one side of blackboard, so saying of " off-centre " arranged.

Summary of the invention

The purpose of this utility model is that a kind of novel movable blackboard will be provided, and a kind ofly is made of the novel movable blackboard that each part can move arbitrarily the polylith small blackboard in framework.

The purpose of this utility model is achieved in that a kind of novel movable blackboard, and first blackboard and second blackboard are installed in the upper ledge, and third blackboard and fourth blackboard are installed in the lower frame, and two ends connect upper ledge and lower frame respectively behind the steel wire penetrating fixed pulley.Upper ledge is respectively equipped with vertical padded coaming with lower frame upper and lower side two.First blackboard, second blackboard, third blackboard and two ends, the fourth blackboard left and right sides are respectively equipped with horizontal padded coaming.First blackboard, second blackboard, third blackboard and fourth blackboard lower end are provided with roller.The horizontal fixed pulley of horizontal steel wire penetrating two ends connect first blackboard and second blackboard or third blackboard and fourth blackboard respectively.

The novel movable blackboard that the utility model provides by the combination by the polylith small blackboard, has realized that the small blackboard of each part can be in framework moves arbitrarily, and mobile blackboard makes the student who is sitting in each corner, classroom can see content on the blackboard.In addition, teacher can move the blackboard of distant place or eminence to most suitable height and write the position, so also can alleviate teacher's working strength.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

The specific embodiment

A kind of novel movable blackboard, first blackboard 1 and second blackboard 2 are installed in the upper ledge 5, and third blackboard 3 and fourth blackboard 4 are installed in the lower frame 6, and steel wire rope 8 passes two ends, fixed pulley 7 back and connects upper ledge 5 and lower frame 6 respectively.Upper ledge 5 two ends is respectively equipped with vertical padded coaming 10 with lower frame about in the of 6.First blackboard 1, second blackboard 2, third blackboard 3 and two ends, fourth blackboard 4 left and right sides are respectively equipped with horizontal padded coaming 11.First blackboard 1, second blackboard 2, third blackboard 3 and fourth blackboard 4 lower ends are provided with roller 9.Horizontal steel wire rope 12 passes horizontal fixed pulley 13 two ends and connects first blackboard 1 and second blackboard 2 or third blackboard 3 and fourth blackboard 4 respectively.

During use, spur upper ledge 5 downwards, under steel wire rope 8 drove, lower frame 6 moved upward.After arriving the appropriate location, under the cushioning effect of vertical padded coaming 10, motion stops.The first that horizontally slips blackboard 1 is because of it has roller 9, so resistance to sliding is very little, under the drive of horizontal steel wire rope 12, second blackboard 2 does relative motion, behind the arrival appropriate location, under the cushioning effect of horizontal padded coaming 11, motion stops, and third blackboard 3 is identical with the motion mode of fourth blackboard 4.The novel movable blackboard that the utility model provides allows teacher blackboard can be placed on optional position in the framework, makes things convenient for the student in each corner in the classroom to know and sees blackboard, also makes things convenient for teacher to write on blackboard.
