Abstract

The utility model discloses a blackboard convenient to wipe, and relates to the blackboard which comprises a blackboard body. The upper part and the lower part of the blackboard body are respectively provided with an upper orbit and a lower orbit. A blackboard wiper is arranged between the upper orbit and the lower orbit. One end of the blackboard wiper is connected with the upper orbit. The other end of the blackboard is connected with the lower orbit. The utility model has the beneficial effects as follows: the blackboard can be wiped once by holding the handle of the blackboard wiper to move the blackboard wiper from one side to the other along the orbits; the blackboard not only saves the schooltime of students, but also saves the physical force of teachers, reduces the burden to give a class, has simple structure, is convenient to make, and is easy to generalize.

Description

A kind of blackboard that makes things convenient for wiping

Technical field

The utility model relates to a kind of blackboard, particularly relates to a kind of blackboard that makes things convenient for the wiping writing.

Background technology

Blackboard is requisite a kind of instrument in the modern teaching, and teacher need write teaching point and be convenient to student's more intuitive understanding knowledge point on blackboard.But present blackboard also exists a lot of defectives, after using, when being write full writing by chalk on the blackboard, need remove the chalk writing on the wiped clean blackboard manually, can reuse, so not only expend very much muscle power and holding time.Increase burden not only for teacher's last teaching, also taken the learning time of the preciousness of students simultaneously.Shortcoming very obviously.

Past and also all have now many about being rich in the innovation and creation of new meaning on the blackboard, for example the patent No. of Patent Office of the People's Republic of China's bulletin on March 8th, 2009 is 200820301085.7 utility model patent blackboard, the design of this patent is to increase a cuboid box in the lower left corner of blackboard to be used to adorn blackboard eraser, solved the problem that blackboard eraser distributes dust because of not having the place to put to a certain extent, do not solved the shortcoming that the manual wipping blackboard is wasted time and energy but throw away.

The utility model content

The utility model is exactly in order to address the above problem, and overcomes the problem that the manual wipping blackboard is wasted time and energy, and provides a kind of blackboard of wiping that makes things convenient for to address the aforementioned drawbacks and problem.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of blackboard that makes things convenient for wiping, comprise the blackboard body, it is characterized in that: the above and below of described blackboard body is respectively arranged with gets on the right track and lower railway, described get on the right track and lower railway between be provided with blackboard eraser, the one end connection of described blackboard eraser is got on the right track, and the other end of described blackboard eraser connects lower railway.

In an embodiment of the present utility model, an end of described blackboard eraser is connected with getting on the right track by the pulley that snaps in getting on the right track, and the other end of described blackboard eraser is connected with lower railway by the pulley that snaps in the lower railway.

In an embodiment of the present utility model, described blackboard eraser is provided with bristle, and described bristle contacts with blackboard.

In an embodiment of the present utility model, described blackboard eraser is provided with handle.

The beneficial effects of the utility model are: only need the handle of hand-held blackboard eraser to get final product for one time to the wiping of another one direction along track, promptly saved the time that the student gives a lesson, saved muscle power to teacher again, reduced burden on class, and simple in structure, easy to make, be easy to promote the use of.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is a schematic diagram of the present utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

A kind of blackboard that makes things convenient for wiping, comprise blackboard body 100, the above and below of blackboard body 100 is respectively arranged with gets on the right track 200 and lower railway 300, get on the right track 200 and lower railway 300 between be provided with blackboard eraser 400, the one end connection of blackboard eraser 400 gets on the right track 200, and the other end of blackboard eraser 400 connects lower railway 300.Thereby with blackboard eraser 400 be fixed on get on the right track 200 and lower railway 300 between.

One end of blackboard eraser 400 200 is connected with getting on the right track by snapping in the pulley 430 that gets on the right track in 200, and the other end of blackboard eraser 400 is connected with lower railway 300 by the pulley 440 that snaps in the lower railway.Be more convenient for the user when using blackboard eraser 400, not need to use very big strength just blackboard eraser 400 can be slid along the track like this.

Blackboard eraser 400 is provided with bristle 420, and bristle 420 contacts with blackboard 100, wipes in 400 at Sliding blackboard, and bristle 420 just can be with the chalk writing wiped clean on the blackboard body 100.

Blackboard eraser 400 is provided with handle 410, and being provided with of handle made things convenient for the user to use blackboard eraser 400, and hand-held when in use handle 410 wipes 400 along the track Sliding blackboard then, and blackboard eraser 400 just can be with the chalk writing wiped clean on the blackboard body 100.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
