Abstract
The utility model relates to a kind of Multi-layer blackboard, it is characterized in that: this Multi-layer blackboard comprises the first plate body, the second plate body, slide block and the first guide rail be embedded in body of wall and the second guide rail; Described first guide rail is vertically arranged, and described slide block also can be slided up and down along this first guide rail by described first guide supporting, and described first plate body is two-sided is equipped with writing surface, and its upper end is articulated with on described slide block by rotating shaft; Described second guide rail is horizontally placed on above described first guide rail, described second plate body is by described second guide supporting and can along this second guide rail horizontal slip, and this second plate body can cover described first plate body surface respectively at two extreme positions of the second slide on rails or the first plate body is exposed completely.Compared with prior art, the beneficial effects of the utility model are: improving by establishing the structure of existing blackboard, increasing the usable floor area of blackboard.This Multi-layer blackboard structure is simple, and easy to operate, write area is three times of the conventional blackboard of identical length and width.
Description
Technical field
The utility model relates to teaching aid technical field, particularly relates to a kind of Multi-layer blackboard.
Background technology
At present, along with country is to the continuous attention of educational undertaking, and drop into continue to increase, the quality of education is greatly improved, the content of courses also more variation.In order to make the content of courses more easy-to-understand, the content of teacher's writing on the blackboard also constantly increases, and this just makes teachers be faced with a problem, has a large amount of writing on the blackboard contents to need to be retained on blackboard, common blackboard area is inadequate, brings a lot of problem to classroom instruction.
Utility model content
The object of the utility model embodiment is for the structural shortcoming of prior art, a kind of Multi-layer blackboard is proposed, this Multi-layer blackboard arranges respectively along the first plate body and second plate body of guide rail movement, and the second plate body can cover described first plate body surface respectively at two extreme positions of its slide on rails or make the first plate body expose completely, first plate body is then two-sided arranges writing surface, realizes two-sided writing function by rotating shaft.Compare with normal blackboard, increase write area.
In order to reach above-mentioned utility model object, a kind of Multi-layer blackboard that the utility model embodiment proposes is achieved through the following technical solutions:
A kind of Multi-layer blackboard, is characterized in that: this Multi-layer blackboard comprises the first plate body, the second plate body, slide block and the first guide rail be embedded in body of wall and the second guide rail; Described first guide rail is vertically arranged, and described slide block also can be slided up and down along this first guide rail by described first guide supporting, and described first plate body is two-sided is equipped with writing surface, and its upper end is articulated with on described slide block by rotating shaft; Described second guide rail is horizontally placed on above described first guide rail, described second plate body is by described second guide supporting and can along this second guide rail horizontal slip, and this second plate body can cover described first plate body surface respectively at two extreme positions of the second slide on rails or the first plate body is exposed completely.
Described rotating shaft is Damping rotation shaft.
Compared with prior art, the beneficial effects of the utility model are: improving by establishing the structure of existing blackboard, increasing the usable floor area of blackboard.This Multi-layer blackboard structure is simple, and easy to operate, write area is three times of the conventional blackboard of identical length and width.
Accompanying drawing explanation
By the description carried out its exemplary embodiment below in conjunction with accompanying drawing, the above-mentioned feature and advantage of the utility model will become apparent and easy understand.
Fig. 1 is the utility model embodiment overall structure schematic diagram;
Fig. 2 is the utility model embodiment principle schematic.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, so that the understanding of technical staff of the same trade:
As shown in Figure 1-2, label represents respectively:
First guide rail 1, slide block 2, first plate body 3, Damping rotation shaft 4, second guide rail 5, second plate body 6, body of wall 7.
There is provided a kind of Multi-layer blackboard in the present embodiment, shown in Figure 1, this Multi-layer blackboard comprises:
First guide rail 1, the sub-track combination be embedded in body of wall 7 by a pair is formed.This antithetical phrase guide rail is all vertically arranged.
Slide block 2, is arranged on the first guide rail 1, is supported and can slide up and down along this first guide rail 1 by the first guide rail 1.
First plate body 3, is two-sidedly equipped with writing surface.Its upper end is articulated with on slide block 3 by Damping rotation shaft 4.First plate body 3 can spin upside down around Damping rotation shaft 4, to demonstrate one of them writing surface.
Second guide rail 5, being embedded in body of wall 7 and being horizontally placed on above the first guide rail 1, the second guide rail 5 exceeds the first guide rail 1 and arranges.
Second plate body 6, one side arranges writing surface.The upper end of the second plate body 6 is slideable to be assemblied on the second guide rail 6, thus to be supported and can along this second guide rail 6 horizontal slip by the second guide rail 6.
Shown in Figure 2, two visible Fig. 2 of extreme position that the second plate body 6 slides on the second guide rail 5, one of them extreme position can cover the surface of the first plate body 3, and now whole Multi-layer blackboard only can write writing on the blackboard in the second plate body 6 surface; Another extreme position can make the first plate body 3 expose completely, and now the first plate body 3 can spin upside down, and two-sidedly all can write.
By embodiment, invention intention of the present utility model and embodiment are described in detail above; but the utility model one of ordinary skill in the art be appreciated that; the above embodiment of the utility model is only one of preferred embodiment of the present utility model; for length restriction; here can not all embodiments of particularize; any enforcement that can embody the utility model claim technical scheme, all in protection domain of the present utility model.
It should be noted that; above content is in conjunction with concrete embodiment further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; under the guidance of above-described embodiment; those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improve or distortion drops in protection domain of the present utility model.
