Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain The utility model, is not used to limit the utility model.
A kind of novel blackboard eraser structure as depicted in figs. 1 and 2, including guide rail 1, connecting rod 2, roller 3 and blackboard eraser master Body 4, the guide rail 1 is installed on the both sides up and down of blackboard main body 5, and the two ends of connecting rod 2 pass through a contiguous block 6 and roller 3 respectively Connection, the inlay card of roller 3 is in the guide rail 1 and can be along the central slot of guide rail 1 slidably, and the blackboard eraser main body 4 is fixed In on connecting rod 2 and can around connecting rod 2 it is axially free rotation 180 °.
Wherein, the blackboard eraser main body 4 is rectangular parallelepiped structure, and the height of its upper top to bottom is more than its left and right sides Width;The bottom of the blackboard eraser main body 4 is provided with a groove 41, and the both sides of groove 41 are provided with VELCRO and hook face 42, described VELCRO hooks the stickup of face 42 and is fixed with cleaning wiping cloth 43;The contiguous block 6 is being provided with some circular grooves with the junction of connecting rod 2 61, head and the tail overlapping is connected the circular groove about 61 and the connecting rod 2 can be moved up and down in circular groove 61;The company Block 6 is connect to form using rubber is made.
A kind of novel blackboard eraser structure that the utility model is mentioned, it is when specifically used, according to above attachment structure, will Blackboard eraser main body 4 is installed in place, not high according to the apparent height of blackboard main body 5, the height of blackboard eraser main body 4 is adjusted, specifically Adjustment connecting rod 2 is adjusted in the upper-lower position on contiguous block 6 in circular groove 61, until blackboard eraser main body 4 is away from the table of blackboard main body 5 Face is highly suitable, convenient to wipe, during blackboard wiping, holds blackboard eraser main body 4, carries out left and right dragging, and the bottom of blackboard eraser main body 4 is glued Connecing fixed cleaning wiping cloth 43 can wipe to the chalk dust on the surface of blackboard main body 5, and the chalk dust after wiping lodges in blackboard In the groove 41 for wiping the bottom of main body 4, the bottom sides of blackboard main body 5 are then fallen to along upper, are wiped quickly, it is simple to operate.
When needing to change cleaning wiping cloth 43, rotating blackboard eraser main body 4 is rotated by 90 ° it so that the bottom surface of blackboard eraser main body 4 Turn up, cleaning wiping cloth 43 is hooked from VELCRO and extractd on face 42, is changed, it is easy to operate.
Some left and right Combined blackboards of correspondence, the utility model is equally applicable, the sub- blackboard that Combined blackboard is accordingly connected Junction occurs uneven, and when wiping at connection side, turnover blackboard wipes main body 4, and flip angle is 90 °, now blackboard Wipe the side of main body 4 and become bottom surface, gap becomes big between blackboard eraser main body 4 and blackboard, can directly slide to next sub- blackboard table Face, then 90 ° of reverse flip, can proceed to wipe, the process, if feeling blackboard eraser main body 4 and the surface of blackboard main body 5 Press close to too tight or too loose, again may be by regulation connecting rod 2 in the upper-lower position of the circular groove 61 on contiguous block 6 to be adjusted It is whole, it is easy to operate
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New spirit and scope are defined.On the premise of the utility model design concept is not departed from, this area ordinary person couple The all variations and modifications that the technical solution of the utility model is made, all should drop into protection domain of the present utility model, this reality With new claimed technology contents, all record in detail in the claims.
