Abstract
The utility model provides a kind of magnetism eraser, comprises blackboard rubbing head, and described blackboard rubbing head is provided with expansion link, and the both sides, the back side of described blackboard rubbing head are provided with magnet.By added an expansion link to blackboard eraser after, short person student erases the board on the ground even if also may stand in, and had expansion link also need not press close to blackboard closely to have wiped, can be stood away wiping, also avoid the phenomenon of the dust adsorption that closely erases the board, because blackboard is magnetic, wiping rear blackboard eraser can also directly be adsorbed on blackboard, gets, takes, with all very convenient.
Description
Technical field
The utility model relates to a kind of convenient and practical magnetism eraser.
Background technology
Erasing the board is the responsibility of each Young Pioneer, is also a kind of behavior embodying pupil's work.Whenever pupil is on duty for the day time, particularly erase the board all very difficult, because pupil's head is short, the letter written with chalk above blackboard can't reach, and step on chair and just can reach wiping, but steps on chair and erase the board and easily step on partially, abnormally dangerous.
Summary of the invention
The purpose of this utility model is to solve the out of reach problem of top letter written with chalk that to erase the board because pupil's head is short, provides a kind of magnetism eraser, by arranging expansion link, facilitating short person student and erasing the board, ensured the personal safety of student.
In order to solve the problems of the technologies described above, the technical solution of the utility model is,
A kind of magnetism eraser, comprise blackboard rubbing head, described blackboard rubbing head is provided with expansion link.Pupil can according to the length of the height adjustable telescopic rod of oneself height and letter written with chalk, and expansion link can be fixed by pull, and operation is very easy.
Further, the both sides, the back side of described blackboard rubbing head are provided with magnet.
Further, the both sides, the back side of described blackboard rubbing head are provided with fixed block, and described magnet is bonded on the outer surface of fixed block.After fixed block is set, magnet is bonded in after on fixed block outer surface, magnet place plane higher than described expansion link so that by whole blackboard eraser by magnet adsorption on blackboard, usual blackboard is that tool is magnetic.
Further, one end of described expansion link is provided with U-shaped fixed mount, the dual-side of U-shaped fixed mount is provided with fixing hole, is bolted after described U-shaped fixed mount wraps up described expansion link end with described expansion link, and described U-shaped fixed mount and described blackboard rubbing head are adhesively fixed.
Or, one end of described expansion link is provided with U-shaped fixed mount, the dual-side of U-shaped fixed mount is provided with fixing hole, and be bolted with described expansion link after described U-shaped fixed mount wraps up described expansion link end, described U-shaped fixed mount is fixedly connected with by screw with described blackboard rubbing head.
By added an expansion link to blackboard eraser after, erase the board on the ground even if short person student also may stand in.During embody rule, the place that on blackboard, letter written with chalk is high is expansion link pull outward, and high place both can have been wiped easily, and short place shrinks back wiping expansion link.And had this expansion link also need not press close to blackboard closely to have wiped, can stand away wiping, also avoid the phenomenon of the dust adsorption that closely erases the board.Because blackboard is magnetic, wiping rear blackboard eraser can also directly be adsorbed on blackboard, gets, takes, with all very convenient.
Accompanying drawing explanation
Fig. 1 is the front view of magnetism eraser specific embodiment described in the utility model;
Fig. 2 is the rear view of magnetism eraser specific embodiment described in the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to shown in Fig. 1-2, this embodiment is a kind of magnetism eraser, comprises blackboard rubbing head 1, is connected and fixed expansion link 2 in the middle part of the back side of blackboard rubbing head 1, and expansion link 2 can pull secured adjusted length, and locked by snap close 21.
One end of expansion link 2 is provided with U-shaped fixed mount 3, and the dual-side of U-shaped fixed mount 3 is provided with fixing hole, and U-shaped fixed mount 3 is connected by bolt 4 with expansion link after wrapping up expansion link 2 end, and U-shaped fixed mount 3 is adhesively fixed with blackboard rubbing head 1.
For the ease of placing blackboard eraser, fixed block 5 is respectively equipped with in the both sides, the back side of blackboard rubbing head 1, the outer surface of each fixed block 5 is adhesively fixed and is provided with magnet 6, after fixed block 5 is set, magnet 6 is bonded in after on fixed block 5 outer surface, magnet 6 place plane is higher than expansion link 2, so that be adsorbed on blackboard by whole blackboard eraser by magnet 6, usual blackboard is that tool is magnetic.
During embody rule, pupil can fix the length of expansion link 2 according to the height pull of oneself height and letter written with chalk, operation is very easy, and the place that on blackboard, letter written with chalk is high is expansion link 2 pull outward, and short place shrinks back wiping expansion link 2.Because blackboard is magnetic, wiping rear blackboard eraser can also directly be adsorbed on blackboard, gets, takes, with all very convenient.
Certainly, in above-described embodiment, in order to gain in strength, U-shaped fixed mount 3 can also be fixedly connected with by screw with blackboard rubbing head 1.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
