Abstract
The utility model discloses a magnetic environmentally-friendly board eraser, which structurally comprises a board eraser support and a board eraser surface, wherein the board eraser support is movably connected with the board eraser surface; and a magnet is additionally arranged on the board eraser. The magnetic environmentally-friendly board eraser has the advantages that the board eraser surface can be conveniently replaced, so economy is realized and the environment is protected; and meanwhile, the magnetic environmentally-friendly board eraser can be directly absorbed on a blackboard surface and is very convenient to use.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of blackboard eraser.
Background technology
Existing blackboard eraser is after using a period of time, because board wiper plane wearing and tearing, aging, at this moment scrub effect must abandon whole blackboard eraser worse and worse, causes waste.On the other hand,, the blackboard eraser groove need be set below blackboard, use very inconvenient for the ease of placing blackboard eraser.
The utility model content
The technical problem that the utility model will solve provides a kind of magnetic Environmentally friendly blackboard eraser, can replace board wiper plane easily, and saving, environmental protection can directly be adsorbed on the blackboard panel simultaneously, and be very convenient to use.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is following.
A kind of magnetic Environmentally friendly blackboard eraser comprises blackboard eraser holder and board wiper plane in the structure, said board wiper plane and blackboard eraser holder flexibly connect, and also are provided with magnet on the blackboard eraser.
As a kind of optimal technical scheme of the utility model, said magnet is magnet piece, magnet strip or the flat thin magnet that is arranged in the blackboard eraser holder.
As a kind of optimal technical scheme of the utility model, said magnet is magnet piece, magnet strip or the flat thin magnet that is arranged on the board wiper plane.
As a kind of optimal technical scheme of the utility model, said magnet is magnet piece, magnet strip or the flat thin magnet that is arranged between blackboard eraser holder and the board wiper plane.
As a kind of optimal technical scheme of the utility model, said magnet is the neodymium iron boron strong magnet.
As a kind of optimal technical scheme of the utility model, said board wiper plane and blackboard eraser holder flexibly connect through magic tape, are the hook face/matte of magic tape in the blackboard eraser holder, should be the matte/hook face of magic tape on the board wiper plane mutually.
As a kind of optimal technical scheme of the utility model, said board wiper plane is connected with blackboard eraser holder snapping, in the blackboard eraser holder pin thread/box is set, relative set box/pin thread on the board wiper plane.
As a kind of optimal technical scheme of the utility model, said board wiper plane and blackboard eraser holder socket connection are provided with plug/slot in the blackboard eraser holder, relative set slot/plug on the board wiper plane.
As a kind of optimal technical scheme of the utility model, said board wiper plane and blackboard eraser holder flexibly connect through slide fastener.
Adopt the beneficial effect that technique scheme produced to be: the utility model after board wiper plane weares and teares gradually, wears out, can be changed board wiper plane easily, thereby reach the purpose of economical environment-protective in use; In addition, owing on the blackboard eraser of the utility model magnet is set, cooperate the irony blackboard, the time spent can directly not be adsorbed on blackboard eraser on the blackboard panel, and is very convenient.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the utility model.
Among the figure: 1, blackboard eraser holder; 2, board wiper plane; 3, magnet.
The specific embodiment
Referring to accompanying drawing, comprise blackboard eraser holder 1 and board wiper plane 2 in the structure of a specific embodiment of the utility model, said board wiper plane 2 flexibly connects through magic tape with blackboard eraser holder 1, is the hook face of magic tape in the blackboard eraser holder 1, should be the hook face of magic tape on the board wiper plane 2 mutually; Board wiper plane 2 flexibly connects with blackboard eraser holder 1, also is provided with neodymium iron boron strong magnet piece 3 between blackboard eraser holder 1 and the board wiper plane 2.
In addition, can also movable connection method such as be connected for snapping, grafting, slide fastener between the blackboard eraser holder 1 of the utility model and the board wiper plane 2; Magnet can also be arranged in the blackboard eraser holder 1 or board wiper plane 2 on, the magnet profile specifically can also be magnet strip or flat thin magnet.
The operation principle of the utility model is: after board wiper plane 2 weares and teares gradually, wears out, can change board wiper plane 2 easily, thereby reach the purpose of economical environment-protective; Owing on the blackboard eraser of the utility model magnet 3 is set, cooperate the irony blackboard, the time spent can directly not be adsorbed on blackboard eraser on the blackboard panel, and is very convenient.
Foregoing description only proposes as the enforceable technical scheme of the utility model, not as the single restrictive condition to its technical scheme itself.
