Abstract
The utility model discloses a blackboard eraser device which comprises two opposite slide rails arranged at two opposite sides of a blackboard and slide plates with two ends capable of being buckled on slide plates on the slide rails in a sliding mode, wherein a wiping lint layer is arranged on each slide plate, and the blackboard is closely attached on the inner side of the wiping lint layer. When the blackboard is installed on the blackboard eraser device and the blackboard is wiped, the blackboard eraser device is capable of achieving wiping of the blackboard eraser by people sliding the slide plates along the slide rails, convenient and fast, time-saving and labor-saving and capable of improving wiping speed.
Description
Technical field
The utility model relates to a kind of educational aid, especially a kind of device for blackboard eraser.
Background technology
Existing teacher generally still adopts chalk-writing when teaching, the mode of blackboard eraser wiping is imparted knowledge to students.Existing blackboard eraser is the little eraser of a rectangle, wastes time and energy during wiping, uses comparatively inconvenience.
The utility model content
For above-mentioned deficiency, technical problem to be solved in the utility model is: how to provide a kind of simple in structure, facilitate blackboard wiping, and wiping speed is high, time saving and energy saving device for blackboard eraser.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model.
A kind of device for blackboard eraser comprises two relative slide rails that are set in parallel in the relative dual-side of blackboard, comprises that also two ends are connected to the slide plate on slide rail slidably, and the slide plate inboard is provided with the wiping flannelette napped fabric layer, and the blackboard setting is close in wiping flannelette napped fabric layer inboard.
After on blackboard, device for blackboard eraser of the present utility model being installed, during blackboard wiping, only need along slide rail direction moving slide board, can complete blackboard-cleaning, very convenient quick, time saving and energy saving, improved wiping speed.
As optimization, also comprise the compression governor motion, described compression governor motion comprises the fixed head that is arranged at the slide plate outside, and fixed head two ends and slide plate are fixed, on fixed head along its length the compartment of terrain be provided with a plurality of hold-down bolts, described hold-down bolt is screwed on fixed head and front end and slide plate offset.After optimizing like this, can rotatably compress bolt by adjusting, hope blackboard place direction hold out against fixed head, make wiping flannelette napped fabric layer and blackboard surface be affixed tighter, the raising wiping effect.Like this, in the time of can or fluffing two kinds of situations because of wearing and tearing at wiping flannelette napped fabric layer and blackboard applying tension, all can regulate by hold-down bolt, make its pressure be in moderate position, be beneficial to blackboard-cleaning.
As further optimization, the two ends of slide plate are connected on slide rail by sliding matching structure slidably, described sliding matching structure comprises described slide rail and is positioned at the slide at fixed head two ends, described slide rail comprises two steel pipes that interval arranged side by side arranges, and has two through holes on described slide and is slidably fitted on two steel pipes of slide rail.Like this, have simple in structure, it is convenient to implement, advantage with low cost adopts steel pipe to make slide rail simultaneously, forms coordinating of 360 degree by whole periphery between slide rail and slide spacing, guaranteed the accuracy that coordinates, adopt simultaneously two steel pipes arranged side by side to guarantee the stationarity that coordinates, therefore can greatly improve the steady degree of reliability of wiping, prevent that common rail structure can be because of the excessive blackboard-cleaning that affects of beating.
In sum, the utlity model has simple in structurely, facilitate blackboard wiping, and wiping speed is high, time saving and energy saving advantage.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During concrete enforcement, as shown in Figure 1, a kind of device for blackboard eraser, comprise two relative slide rails 1 that are set in parallel in the relative dual-side of blackboard, comprise that also two ends are connected to the slide plate 2 on slide rail 1 slidably, slide plate 2 inboards are provided with wiping flannelette napped fabric layer 3, and wiping flannelette napped fabric layer 3 inboards are close to blackboard 4 and are arranged.Also comprise the compression governor motion, described compression governor motion comprises the fixed head 5 that is arranged at the slide plate outside, fixed head 5 two ends and slide plate 2 is fixing, on fixed head 5 along its length the compartment of terrain be provided with a plurality of hold-down bolts 6, described hold-down bolt 6 is screwed on fixed head 5 and front end and slide plate 2 offset.During concrete enforcement, the two ends of slide plate 2 are connected on slide rail 1 slidably by sliding matching structure, described sliding matching structure comprises described slide rail 1 and is positioned at the slide 7 at fixed head two ends, described slide rail 1 comprises two steel pipes that interval arranged side by side arranges, and has two through holes on described slide 7 and is slidably fitted on two steel pipes of slide rail 1.
