Abstract
The utility model provides an utricule formula blackboard eraser that prevents dust, package rubbing board wipes water storage chamber board (3) of cavity (1), bottom surface posting cavernosum (2), bottom surface tip that the top surface tip of water storage chamber board (3) passes through spring (4) to connect blackboard eraser cavitys (1), and the bottom surface of water storage chamber board (3) sets up apopore I (5) and its top surface and sets up inlet opening (6), inlet opening (6) intercommunication sets up bottom apopore II (10) of the rubber water storage bag (9) in the middle part of blackboard eraser cavity (1), and clamp plate (7) is connected at the top of rubber water storage bag (9), articulated fixed the setting in bracing piece (11) at blackboard eraser cavity (1) top in the tip of tip hinge joint linkage (8) of clamp plate (7) and the middle part of connecting rod (8), and the other end of connecting rod (8) articulates push rod (12) connected at water storage chamber board (3) tip. The utility model provides a dustproof blackboard eraser carries out moist contact through control blackboard eraser working face and the face that has the dust, and dry dust is no longer kicked up cleaning the in -process, and peripheral personnel no longer inhale the dust, consequently provide the teaching environment of a health.
Description
Technical field
The utility model relates to realia field, specifically a kind of envelope type dust-proof blackboard eraser.
Background technology
Blackboard eraser can produce a large amount of dust granules in wiping process, and the dust granules dancing in the air had both affected surrounding space environment, caused again the suction of periphery personnel dust granules, affected the healthy of environment and people.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the utility model improves existing blackboard eraser, a kind of envelope type dust-proof blackboard eraser is provided, carry out moistening contact by controlling blackboard eraser working face with the plate face with dust, dry dust is no longer kicked up in wiping process, periphery personnel no longer suck dust, and therefore a kind of teaching environment of health is provided.
For achieving the above object, the technical scheme that the utility model is taked is: comprise blackboard eraser cavity, the water storage cavity plate of cavernous body is posted in bottom surface, the top end of water storage cavity plate is wiped the bottom end of cavity by spring coupling plate, the bottom surface of water storage cavity plate sets out water hole I and its end face arranges inlet opening, described inlet opening is communicated with the bottom apopore II of the rubber water reservoir that is arranged on blackboard eraser cavity middle part, the top of rubber water reservoir connects pressing plate, the hinged support bar that is fixedly installed on blackboard eraser cavity top in the end of end articulated linkage of pressing plate and the middle part of connecting rod, the other end of connecting rod is articulated and connected at the push rod of water storage cavity plate end.
When blackboard wiping face, press the water storage cavity plate with sponge, water storage cavity plate can promote push rod and up move, up move with the other end of connecting rod by down moving with support bar fulcrum in one end of push rod drivening rod, down the pressing plate of motion will compressing rubber water reservoir, now the water in rubber water reservoir will be out squeezed by apopore II, enter by inlet opening in the cavity of water storage cavity plate from apopore II water out, water in cavity will be attached in cavernous body by apopore I, now moistening cavernous body and the plate face with dust carry out moisteningly contacting and dust being wiped out, owing to having designed rubber water reservoir, ensure that wiping process water can continue cavernous body to carry out moistening, ensure the continuity of moistening wiping process, therefore dry dust is no longer kicked up in wiping process, periphery personnel no longer suck dust.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is an embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, comprise blackboard eraser cavity 1, the water storage cavity plate 3 of cavernous body 2 is posted in bottom surface, the top end of water storage cavity plate 3 connects the bottom end of blackboard eraser cavity 1 by spring 4, the bottom surface of water storage cavity plate 3 sets out water hole I5 and its end face arranges inlet opening 6, described inlet opening 6 is communicated with the bottom apopore II10 of the rubber water reservoir 9 that is arranged on blackboard eraser cavity 1 middle part, the top of rubber water reservoir 9 connects pressing plate 7, the hinged support bar 11 that is fixedly installed on blackboard eraser cavity 1 top in the end of the end articulated linkage 8 of pressing plate 7 and the middle part of connecting rod 8, the other end of connecting rod 8 is articulated and connected at the push rod 12 of water storage cavity plate 3 ends.
Rubber water reservoir 9 is herein that elastic material is made, in the time not re-using this blackboard eraser, under the restoring force effect of spring 4, blackboard eraser cavity 1 will drive push rod 12 down to move, 8 leverages of connecting rod herein, connecting rod 8 will be with dynamic pressure plate 7 to be no longer pressed on rubber water reservoir 9, therefore rubber water reservoir 9 will produce elasticity recovery, apopore II10 herein makes by pinprick mode, under normal condition, if utricule is not compressed in the pinprick hole that this kind is arranged on rubber water reservoir 9, water can not flow out from utricule the inside, producing the rubber water reservoir 9 that elasticity recovers can produce toward the suction in utricule apopore II10 simultaneously, therefore water more can not flow out in utricule.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present utility model, also should belong to protection domain of the present utility model.
