Abstract
The utility model discloses an adsorption magnetic blackboard eraser which comprises a blackboard eraser, a torsion spring, a movable absorption block and a magnet; one end of the eraser board of the blackboard eraser is connected with the movable absorption block through the torsion spring; and the magnet is arranged in the movable absorption block. The blackboard eraser can rotate around the torsion spring through the movable magnetic absorption block on one end of the blackboard eraser, so that the movable absorption block is kept level with the blackboard eraser and can be absorbed on a blackboard when not in use, and the movable absorption block only needs to rotate for a certain angle and the normal use of the blackboard eraser is not affected when in use; and the product has the advantages of simple structure, convenient operation, and very high practicality and marketing value.
Description
Technical field
The utility model relates to a kind of blackboard eraser, more particularly relates to a kind of blackboard eraser that has magnetic that is adsorbed on the blackboard surface.
Background technology
Blackboard eraser is the learning tool that we use always, we are tending to run into the situation that can not find blackboard eraser in the usefulness at ordinary times, because blackboard eraser can not be placed on the blackboard, and existing blackboard generally all contains one deck sheet iron or iron plate edge, if in without blackboard eraser, blackboard eraser can be adsorbed on the surface of blackboard so we imagine us, just can avoid blackboard eraser be placed on other places need with in and situation about can not find has taken place.
Summary of the invention
In order to address the above problem, the utility model provides a kind of absorption type magnetism eraser, the movable absorption type piece that has magnetic by blackboard eraser one end can rotate around torsion spring, make movable absorption type can be adsorbed on the blackboard in not time spent and blackboard eraser maintenance level, the time spent only need rotate to an angle and just can not influence blackboard eraser and normally use.
A kind of absorption type magnetism eraser comprises blackboard eraser, torsion spring, movable Attraction block and magnet, and the end on the wiping board of described blackboard eraser connects a movable Attraction block by torsion spring, and magnet is installed in the described movable Attraction block.
The two ends of described torsion spring angle under normal conditions are 90 °, and described torsion spring one end and blackboard eraser wiping board surface vertical fixing are installed, and the other end and movable Attraction block surface secured in parallel are installed.
The beneficial effects of the utility model are: simple in structure, easy to operate, have very big practicality and market popularization value.
Description of drawings
Structural representation when Fig. 1 normally places for the utility model;
Structural representation when Fig. 2 uses for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Structural representation when being illustrated in figure 1 as the utility model and normally placing, a kind of absorption type magnetism eraser, comprise blackboard eraser 1, torsion spring 3, movable Attraction block 2 and magnet 4, end on the wiping board of described blackboard eraser 1 connects a movable Attraction block 2 by torsion spring 3, in the described movable Attraction block 2 magnet 4 is installed.
The two ends of torsion spring 3 angle under normal conditions are 90 °, and described torsion spring 3 one ends and blackboard eraser 1 wiping board surface vertical fixing are installed, and the other end and movable Attraction block 2 surperficial secured in parallel are installed.State as shown in Figure 2 when using blackboard eraser of the present utility model, only need catch on finger movable Attraction block 2, makes it keep case of bending, just can not occur movable Attraction block 2 when blackboard eraser erases the board like this and rub with blackboard.After having wiped blackboard, unclamp the movable Attraction block 2 of finger because the natural twisting force of torsion spring 3 is returned to blackboard eraser 1 and keep horizontal state simultaneously, can be adsorbed on the blackboard surface.
Claims (2)
1. an absorption type magnetism eraser comprises blackboard eraser, it is characterized in that, also comprises torsion spring, movable Attraction block and magnet, and the end on the wiping board of described blackboard eraser connects a movable Attraction block by torsion spring, and magnet is installed in the described movable Attraction block.
2. absorption type magnetism eraser as claimed in claim 1 is characterized in that, the two ends of described torsion spring angle under normal conditions are 90 °, and described torsion spring one end and blackboard eraser wiping board surface vertical fixing are installed, and the other end and movable Attraction block surface secured in parallel are installed.
