Description
Technical field
The utility model relates to a kind of blackboard eraser dust and dispels device, particularly relates to the dedusting in the box-like enclosed environment of a kind of blackboard eraser, convenient again environmental protection, and the hand-rail type blackboard clean dust of favourable teachers and students' health is dispelled device.
Background technology
School's chalk on class commonly used and blackboard.When being stained with the chalk powder eraser blackboard, dust pollution can be very serious.Therefore, often take blackboard eraser on hard thing, to pat to dispel chalk dust, but produce the problem of two degree dust pollutions.
The utility model content
For the problems referred to above, main purpose of the present utility model is to provide the dedusting in the box-like enclosed environment of a kind of blackboard eraser, convenient again environmental protection, and the hand-rail type blackboard clean dust of favourable teachers and students' health is dispelled device.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of hand-rail type blackboard clean dust is dispelled device, described hand-rail type blackboard clean dust is dispelled device and is comprised box body, described box body the inside is fixed with the anchor clamps of fixed black blackboard eraser, also be provided with the box door with transparency window on the described box body on the one side, on the side of the box body relative with the box door hole is set, there is rotating shaft to pass through in the hole, described rotating shaft is connected with ratchet and crank, described ratchet is arranged in the box body, described crank is arranged on outside the box body, be connected with wind on the described crank, anchor clamps one side in the described box body is provided with metal and pats sheet, described beating sheet one end is connected with spring leaf, and that end away from patting sheet of described spring leaf is fixed on the described box body.
In an implementation example of the present utility model, the one side size that metal is patted the surface area that faces toward the blackboard eraser part of sheet and the felt that blackboard eraser need to be dispelled dust is identical.
In an implementation example of the present utility model, the one side of the felt of described blackboard eraser is 10-30mm with the distance range of patting sheet, and distance range also can carry out suitable modification according to the actual needs.
It is box body that the hand-rail type blackboard clean dust is dispelled device, and front have transparency window to open.Side blackboard eraser anchor clamps in the box; The metal that preposition length and width are suitable is patted sheet, and its root is fixed in rear wall by spring leaf; Spring leaf has ratchet by blackboard eraser one side, and its axle center is passed rear wall and linked to each other with crank handle, pats sheet when spring leaf discharges and is close to blackboard eraser felt place.Thereby ratchet backs down spring leaf regularly or discharges and finishes stroke during swinging handle.
Open front window during use, clamp clamps blackboard eraser back.Swinging handle behind the window of pass is patted the i.e. frequent blackboard eraser felt of patting of sheet, and owing to the effect of gravity and inertia, the chalk dust on the blackboard eraser just can easily be dispelled.
Positive progressive effect of the present utility model is: the hand-rail type blackboard clean dust that the utility model provides is dispelled utensil and had the following advantages: the hand-rail type blackboard clean dust that the utility model provides is dispelled device, with low cost, make easily, operate light, blackboard eraser is dedusting in enclosed environment, can effectively reduce the classroom dust pollution, be conducive to the healthy of the teachers and students of school.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Fig. 1 is structural representation of the present utility model.As shown in Figure 1: the hand-rail type blackboard clean dust that the utility model provides is dispelled device, the utility model comprises box body 1, box body 1 the inside is fixed with the anchor clamps 3 of fixed black blackboard eraser 2, also be provided with the box door 4 with transparency window 5 on the box body 1 on the one side, on the side of the box body 1 relative with box door 4 hole is set, there is rotating shaft 7 to pass through in the hole, rotating shaft 7 is connected with ratchet 6 and crank 9, ratchet 6 is arranged in the box body 1, crank 9 is arranged on outside the box body 1, is connected with wind 8 on the crank 9, and anchor clamps 3 one sides in the box body 1 are provided with metal and pat sheet 11, pat sheet 11 1 ends and be connected with spring leaf 10, that end away from patting sheet 11 of spring leaf 10 is fixed on the box body 1.In an implementation example of the present utility model, metal pat sheet 11 need to dispel the one side of felt of dust facing to the surface area of blackboard eraser 2 parts and blackboard eraser 2 big or small identical or need to dispel the surface area of one side of the felt of dust greater than blackboard eraser 2.In an implementation example of the present utility model, the one side of the felt of blackboard eraser 2 is 10-30mm with the distance range of patting sheet 11, and distance range also can carry out suitable modification according to the actual needs.
In use, open transparency window 5, shake wind 8 behind the window of pass, pat the i.e. frequent felt of patting blackboard eraser 2 of sheet 11, owing to the effect of gravity and inertia, the chalk dust on the blackboard eraser 2 just can easily be dispelled.Open the transparency window 5 on the box door 4 after the use, pour chalk dust into dustbin and get final product.
