Abstract
The utility model discloses a folding blackboard eraser. The folding blackboard eraser comprises a blackboard eraser body and an erasing body. The blackboard eraser body comprises a first body (1) and a second body (6), wherein the first body (1) and the second body (6) are connected through a rotation shaft (2), and the included angle between the first body (1) and the second body (6) is 0 degree or 180 degrees through rotation of the rotation shaft (2). The length of the blackboard eraser is adjusted by opening the first body and the second body and can be twice the original length, and therefore the erasing area is doubled, the erasing efficiency is improved, and the problem that it wastes time and labor in the process of large-area erasing is effectively solved.
Description
Technical field:
The utility model relates to clipboard blackboard eraser, relates in particular to a kind of blackboard eraser that can be folding.
Background technology:
Be generally used for the blackboard eraser of blackboard or blank, only possess fixing form, the disposable area of wiping is certain, possesses the feature of flexibility in the time that small size is wiped, but wastes time and energy in the time that whole plate large area is all wiped.Particularly, for the larger lecture theater of some areas, the area of blackboard or blank is very large, and in the time writing completely whole plate and need to wipe, common blackboard eraser is wiped more difficult.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of blackboard eraser that can regulate blackboard eraser length, by regulating length to make the disposable area change of wiping, make blackboard eraser in actual use, both can wipe flexibly indivedual small sizes region, can rapidly and efficiently wipe again large area region, thereby make a blackboard eraser meet the multiple needs of wiping.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is:
A kind of folding blackboard eraser, comprises blackboard eraser main body, and described blackboard eraser main body is divided into the first main body and the second main body, and the first main body is connected by rotating shaft with the second main body; The first main body and the second main body rotate by rotating shaft that to make their angle be 0 degree (blackboard eraser state A) or 180 degree (blackboard eraser state B);
The first described main body and the second main body are respectively equipped with the first rub body and the second rub body.
The first described main body outside is provided with buckle stiff end near one end of rotating shaft, the second main body outside is provided with buckle rotating shaft near one end of rotating shaft, buckle rotating shaft is flexibly connected with buckle round end, be 180 while spending at the first main body and the second main body angle, buckle round end rotates with buckle stiff end and is connected and fixed centered by buckle rotating shaft, makes blackboard eraser state B Stability Analysis of Structures.
The utility model regulates the length of blackboard eraser by blackboard eraser the first main body and the two-part folding of the second main body, make blackboard eraser length become original twice, thereby make disposable one times of the enlarged areas of wiping, improve efficiency of erasing, efficiently solve the problem wasting time and energy in the time that large area is wiped, make a blackboard eraser possess small size simultaneously and wipe flexibly the feature of wiping fast with large area.
Brief description of the drawings:
Fig. 1 is the structural representation (overlooking) of the utility model state A.
Fig. 2 is the structural representation (overlooking) of the utility model state B.
Fig. 3 is the structural representation (main looking) of the utility model state B.
In figure: 1-the first main body, 2-rotating shaft, 3-buckle stiff end, 4-buckle round end, the rotating shaft of 5-buckle, 6-the second main body, 7-the first rub body, 8-the second rub body.
Detailed description of the invention:
In order to understand more clearly the utility model, set forth a kind of detailed description of the invention of the present utility model below in conjunction with accompanying drawing.
The folding blackboard eraser of one as shown in Figure 1, a kind of folding blackboard eraser, comprises blackboard eraser main body, described blackboard eraser main body is divided into the first main body 1 and the second main body 6, the first main bodys 1 are connected by rotating shaft 2 with the second main body 6; It is 0 degree (blackboard eraser state A) or 180 degree (blackboard eraser state B) that the first main body 1 and the second main body 6 make their angle by rotating shaft 2 rotations; In the first main body 1 and the second main body 6, be respectively equipped with the first rub body 7 and the second rub body 8.Described for rub body felt, silk floss fabric or water-absorbing sponge etc. make.
The first described main body 1 outside is provided with buckle stiff end 3 near one end of rotating shaft 2, the second main body 6 outsides are provided with buckle rotating shaft 5 near one end of rotating shaft 2, buckle rotating shaft 5 is flexibly connected with buckle round end 4, be 180 while spending at the first main body 1 and the second main body 6 angles, buckle round end 4 rotates with buckle stiff end 3 and is connected and fixed centered by buckle rotating shaft 5, makes blackboard eraser state B Stability Analysis of Structures.
Make the constitutionally stable implementation of blackboard eraser state B can be also: in the rotating shaft 2 that connects the first main body 1 and the second main body 6, to be provided with screw thread and nut, to screw nut and can make blackboard eraser state B Stability Analysis of Structures.
Blackboard eraser, in the time of state A, is wiped angle flexible, and the needs of wiping with small size are wiped in the amendment that can meet indivedual words; In the time of state B, blackboard eraser length increases greatly, can meet the needs that whole board wiper removes and large area is wiped.
The utility model has effectively solved the problem of wiping fast large-area writing plate, in the case of not increasing other blackboard eraser, only the simple structure that changes traditional blackboard eraser has just met needs, a blackboard eraser has been had simultaneously and wipe flexibly and wipe fast two kinds of features.
