Abstract
The utility model relates to an over -and -under type blackboard eraser, including support, shell and sponge strip, the support is for fixing the slide rail in two opposition sides on the blackboard, the shell is for the inside cube that undercuts and just be equipped with the notch to the one side of blackboard, and the both ends of shell are equipped with with slide rail complex slider and are used for taking out the opening of sponge strip, the sponge strip is inside some is located the shell, and another part is stretched out through the notch and is contacted with the blackboard. The blackboard is cleaned to sponge strip through long, and efficiency is fast, and cooperation through slider and slide rail makes when blacking the board more laborsavingly, and the sponge strip can be convenient pulls down and wash or clear up the dust, and drenches the sponge can reduce the dust when blacking the board.
Description
Technical field
The utility model relates to a kind of blackboard eraser and particularly relates to the wiping of a kind of lifting blackboard.
Background technology
Traditional blackboard eraser area is little, and when monoblock blackboard all needs to wipe, labour intensity is large, and effect is undesirable, and dust is many, is unfavorable for that teachers and students are healthy, and we need a kind ofly not only can improve the efficiency erased the board but also the blackboard eraser that can reduce dust.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lifting blackboard and wipes, and by increasing the area of blackboard eraser blackboard eraser being provided with strip, thus improves the efficiency erased the board, and solves traditional blackboard and to erase the board the problem that efficiency is low, dust is many.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of lifting blackboard is wiped, and it is characterized in that: comprise support, shell and sponge strip; Described support is the slide rail being fixed on blackboard two opposite side; Described shell is the cube emptied of inside and is just provided with notch to the one side of blackboard, and the two ends of described shell are provided with the slide block that coordinates with described slide rail and the opening for extracting described sponge strip out; A described sponge strip part is positioned at enclosure, and another part is stretched out by notch and contacts with blackboard.
Further, described shell, sponge strip respectively have two, and each shell and a sponge strip form a rub piece; Two described rub pieces be arranged in parallel.
The beneficial effect of above-mentioned further scheme is: two rub pieces be arranged in parallel, can improve the efficiency erased the board further, and if the sponge strip in one of them rub piece is got wet, then can reduce dust.
Further, the two ends of described shell are respectively equipped with a catch, and opening is blocked in one end of described catch, and the other end is connected with shell by rotating shaft.
The beneficial effect of above-mentioned further scheme is: block opening by catch and can prevent sponge strip from running out of from opening part.
The beneficial effects of the utility model are: by long sponge strip blackboard wiping, efficiency is fast, more laborsaving when making to erase the board by the cooperation of slide block and slide rail, and sponge strip can pull down cleaning or cleaning dust easily, and drench sponge and can reduce dust when erasing the board.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is a kind of structural representation implemented under state of the utility model.
Fig. 2 is the structural representation of housing parts of the present utility model.
1. supports in figure; 2. shell; 3. sponge strip; 4. slide block; 5. catch; 6. blackboard.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining utility model, is not intended to limit the scope of utility model.
Lifting blackboard is as shown in Figure 1 and Figure 2 wiped, and comprises support, shell and sponge strip; Described support is the slide rail being fixed on blackboard two opposite side; Described shell is the cube emptied of inside and is just provided with notch to the one side of blackboard, and the two ends of described shell are provided with the slide block that coordinates with described slide rail and the opening for extracting described sponge strip out; A described sponge strip part is positioned at enclosure, and another part is stretched out by notch and contacts with blackboard.Described shell, sponge strip respectively have two, and each shell and a sponge strip form a rub piece; Two described rub pieces be arranged in parallel.The two ends of described shell are respectively equipped with a catch, and opening is blocked in one end of described catch, and the other end is connected with shell by rotating shaft.
Two rub pieces be arranged in parallel, can improve the efficiency erased the board further, and if the sponge strip in one of them rub piece is got wet, then can reduce dust.Blocking opening by catch can prevent sponge strip from running out of from opening part.By long sponge strip blackboard wiping, efficiency is fast, more laborsaving when making to erase the board by the cooperation of slide block and slide rail, and sponge strip can pull down cleaning or cleaning dust easily, and drenches sponge and can reduce dust when erasing the board.And two rub pieces can mutually away from setting, such as one upper, another under, or one left another on the right side, the efficiency erased the board like this is higher, can obey nearby principle, and which rub piece is which rub piece just use close to the place of required wiping.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
