Description
Affiliated technical field
The utility model is used blackboard eraser for teaching, particularly adopts mechanical system not have the blackboard eraser of electric dust suction.
Background technology
Existing dust-free black board eraser is made of brush body, housing, bonnet and dust collecting system, dust collecting system drives the series of gears transmission by a wheel that rolls on blackboard, the blast fan that drives the brush body rear portion at last rotates, absorb dust, this device needs the series of gears transmission, and structure is complicated, and this device adopts the fan dust suction, absorb not thoroughly, also dust is dispelled sometimes.
Summary of the invention
Of the present utility modelly be to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, can absorb the nothing electricity dust-sucking eraser of dust preferably.
Solution of the present utility model is: do not have electric dust-sucking eraser housing and be provided with cylinder brush body, housing, bonnet and dust storage groove, be provided with two fixed heads by the biside plate place in the housing, have oval axis hole on the fixed head, the rotating shaft of cylinder brush body is inserted in the oval axis hole, in the rotating shaft of cylinder brush body, be with ratchet near fixed head, be fixed with the ratchet that cooperates with ratchet on the fixed head, connecting one on the housing puts in housing, the scraper plate that the end contacts with the brush body face forms dust storage groove between corresponding scraper plate and housing, the bonnet.When erasing the board, the cylinder brush body contacts with blackboard, and cylinder brush body rotation direction makes ratchet and pawl teeth fashionable, and the cylinder brush body can't be rotated further, and the brush finish of cylinder brush body contacts with blackboard and makes chalk dust be adsorbed on the rotary broom surface; Mobile blackboard brush round about again then, at this moment ratchet and ratchet break away from, and the cylinder brush body rotates, and cylinder brush body rotation process middle scraper scrapes the chalk dust of brush finish absorption in the dust storage groove, and moving so repeatedly can be clean with blackboard eraser, and no chalk dust flies upward.In the purpose that is provided with oval axis hole on the fixed head is when ratchet and ratchet break away from, stayed the space that the rotating shaft that makes the cylinder brush body when ratchet leaves ratchet can be rotated, the brush finish of solution intermediate roll brush body of the present utility model can be sponge, felt, cloth, pig palm fibre, wooden monofilament or fine and closely woven plastics silk.
The utility model advantage compared with prior art: because the utility model is provided with the fixed head of band slotted eye in housing, be fixed with ratchet on the fixed head, ratchet with click-fit is arranged on the cylinder brush body, and on housing, be provided with scraper plate, when cylinder brush body absorption dust when the meshing direction of ratchet and ratchet is rotated in brush finish, scraper plate blows into the dust in the brush finish in the dust storage groove when mobile round about, the motion blackboard brush can be wiped dust and store repeatedly back and forth, corresponding the utility model is simple in structure, can gather dust preferably, prevent that chalk dust from flying upward.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model embodiment side sectional view.
The specific embodiment
The utility model embodiment such as Fig. 1, shown in Figure 2: as not have electric dust-sucking eraser and comprise cylinder brush body (1), housing (2), bonnet (3), be located at the fixed head (4) that leans on side plate in the housing, insert fixed head (4) and go up the rotating shaft (6) of the cylinder brush body (1) in the slotted eye (5), fixing ratchet (7) is gone up in rotating shaft (6), be fixed on fixed head (4) and go up the ratchet (8) that cooperates with ratchet (7), housing (2) is gone up and connect the scraper plate (9) that puts in and contact with the brush finish of cylinder brush body (1) in housing (2), be fixed near bonnet (3) by fixed head (4) and locate, and contact with the brush finish of cylinder brush body (1) scrape lath (10), the other end housing (2) that scraper plate (9) is corresponding is gone up and connect the dust block board (12) that puts in housing (2), by scraper plate (9), dust block board (12) and housing (2), the dust storage groove that forms between the bonnet (3) is wherein scraped lath (10) and is in the strip hole (11) of inserting the oblique top of opening on the fixed head (4) and is fixed on the fixed head (4).The purpose that lath (10) is scraped in setting is to carry out secondary to scrape ash, make the chalk dust that is adsorbed in the brush finish obtain cleaning more completely, brush finish on cylinder brush body (1) simultaneously is because too much with the blackboard friction, after being worn, the effect of scraper plate (9) may weaken relatively, at this moment scrape lath (10) owing to can move in strip hole (11), the corresponding below that moves on to automatically still can be cleaned preferably to the chalk in the brush finish after the wearing and tearing.On the corresponding other end housing of scraper plate (9), connect dust block board (12), can prevent that chalk dust from outwards flying upward in dust storage groove, scraper plate (9) also plays this effect simultaneously, the major axis of the slotted eye (5) on the present embodiment fixed head (4) is a horizontal direction, opens bonnet (3) and can outwell the dust of storage.
Claims (3)
1, a kind of no electric dust-sucking eraser, housing (2) is provided with cylinder brush body (1), bonnet (3) and dust storage groove, it is characterized in that: be provided with two fixed heads (4) by the biside plate place in the housing (2), have oval axis hole (5) on the fixed head (4), the rotating shaft (6) of cylinder brush body (1) is inserted in the oval axis hole (5), in the rotating shaft (6) of cylinder brush body (1), be with ratchet (7) near fixed head, be fixed with the ratchet (8) that cooperates with ratchet (7) on the fixed head (4), housing (2) is gone up connection one and put in the scraper plate (9) that the end contacts with the brush body face in housing (2).
