Abstract
The invention relates to a blackboard with an eraser. The blackboard comprises a blackboard body and the eraser, guide rails are arranged on the two sides of the blackboard body respectively, the guide rails on the two sides are connected with an eraser cross rod through sliding blocks, the eraser is installed on the eraser cross rod, and reset springs are connected between the eraser cross rod and the upper ends of the guide rails on the two sides respectively. The width of the eraser is equal to the width of the blackboard body. The upper ends of the guide rails are connected with spring adjusting bases, and the guide rails are in adjustable connection with the reset springs through the spring adjusting bases. The guide rails are in the shape of a T. The eraser and the eraser cross rod are connected detachably. According to the blackboard, the eraser cross rod and the eraser are moved upwards and downwards, then all characters on the blackboard body can be cleared away completely, and the problem that when an eraser in the prior art is used for wiping chalk characters, the hands, clothes and the face are polluted due to the fact that chalk dust flies everywhere is solved. The technical problem that effort is wasted due to the fact that the arms move back and forth when the blackboard is wiped is solved, and the blackboard with the eraser has the advantages of being convenient to use, high in elimination efficiency, simple in structure and the like.
Description
Technical field
The present invention relates to a kind of blackboard, especially relate to a kind of blackboard with wiping board.
Background technology
Existing blackboard eraser is to be made by the material of loading onto felt one class above plank and easily wipe letter written with chalk.When erasing the board, although letter written with chalk has been wiped, chalk dust flies upward everywhere, the hand of making dirty, clothes and face.Arm moves in turn back and forth owing to erasing the board, also sweat very, in addition, when moving in turn back and forth, also strengthen Air Flow, made the farther of diffusion that dust wafts, contaminated environment, long-term suction dust is very unfavorable to student and teacher's physical and mental health, and dust from flying is very unhygienic simultaneously, and the existing blackboard eraser life-span is short, waste of material is serious, does not meet the theory of national energy-saving environmental protection.
Summary of the invention
The present invention will provide a kind of blackboard with wiping board, and this blackboard has easy to use, can remove cleanly the font on blackboard, and elimination efficiency is high, simple in structure.
For achieving the above object, technical scheme of the present invention is: a kind of blackboard with wiping board, comprise blackboard body, blackboard eraser, blackboard body both sides are respectively equipped with guide rail, two side rails connect blackboard eraser cross bar by slide block, above blackboard eraser cross bar, blackboard eraser is housed, between blackboard eraser cross bar and two side rails upper ends, is connected with respectively back-moving spring.
The width of blackboard eraser equals the width of blackboard body.Guide rail upper end is connected with spring adjustment seat, and by the adjustable connection back-moving spring of spring adjustment seat.Guide rail is T shape guide rail.Releasable connection between blackboard eraser and blackboard eraser cross bar.
The beneficial effect that the present invention compared with prior art has is: the present invention is by moving up and down blackboard eraser cross bar and blackboard eraser, just the font on blackboard body all can be disposed cleanly, solved the blackboard eraser of prior art when wiping chalk word, chalk dust but flies upward everywhere, the hand of making dirty, clothes and face.And the arm technical problem of sweat that moves in turn back and forth while erasing the board, and have easy to use, the feature such as elimination efficiency is high, simple in structure.

Fig. 1 is structural upright schematic diagram of the present invention;
Fig. 2 is structural front view of the present invention;
Fig. 3 is the left cutaway view of Fig. 2;
Fig. 4 is the top view of Fig. 2;
Fig. 5 is use view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figures 1 to 4, a kind of blackboard with wiping board, comprises blackboard body 1, blackboard eraser 2, guide rail 3, blackboard eraser cross bar 4, back-moving spring 5, spring adjustment seat 6, slide block 7.
Blackboard body 1 both sides fixedly mount respectively a guide rail 3, sliding connection slide block 7 in two side rails 3, on two slide blocks 7, be fixedly connected with blackboard eraser cross bar 4, blackboard eraser cross bar 4 is equipped with blackboard eraser 2 above, the width of blackboard eraser 2 equals the width of blackboard body 1, and contact with 1 of blackboard body, between blackboard eraser cross bar 4 and two side rails 3 upper ends, be connected with respectively back-moving spring 5.Its middle guide 3 upper ends are connected with spring adjustment seat 6, and by the adjustable connection back-moving spring 5 of spring adjustment seat 6.Guide rail 3 is T shape guide rail.Releasable connection between blackboard eraser 2 and blackboard eraser cross bar 4.
As shown in Figure 5, during use, firmly blackboard eraser cross bar 4 is moved down, make font on 1 of blackboard eraser 2 erasing blackboard body etc.When blackboard eraser 2 moves to behind blackboard body 1 bottom, remove firmly (letting go), blackboard eraser cross bar 4 is moved upward to blackboard body 1 top under back-moving spring 5 effects, again 1 of blackboard body has been wiped one time.
