Description
The utility model is a kind of dust-free black board eraser, and it mainly comprises housing, and the blackboard eraser body that is loaded in the housing is formed.
Present widely used blackboard eraser in use, dust from flying pollutes room air, has had a strong impact on teachers and students' physical and mental health.For addressing this problem, also have many inventors for this reason and Development and design some electric dust absorption blackboard erasers, but because of its complex structure, cost is higher and all be not used widely.
The purpose of this utility model just is to overcome above-mentioned weak point of the prior art, and provides a kind of simple and reasonable for structure, the dust-free black board eraser of low cost of manufacture.
The purpose of this utility model can adopt following measure to realize:
Dust-free black board eraser of the present utility model mainly comprises housing, is loaded on the compositions such as blackboard eraser body in the housing; Be provided with dust collecting trough around the blackboard eraser body, in the both sides of blackboard eraser body one control of dust baffle plate be installed respectively, the two ends of control of dust baffle plate all are connected with roller by connecting rod.
Connecting rod in the utility model is installed in housing up and down in two end slots by hinge, and an end of connecting rod is installed in the draw-in groove of control of dust baffle plate end, and the other end combines by bearing pin and roller; The upper edge of the cell wall of dust collecting trough and control of dust baffle plate all is bonded with the strip of paper used for sealing of being made by soft material.
Dust-free black board eraser of the present utility model in use, dependence is installed in the blackboard eraser up and down roller at two ends and the frictional force between the blackboard, drive the control of dust baffle plate by connecting rod, make of the change of control of dust baffle plate along with the blackboard eraser direction of motion, do the upper and lower displacement campaign in the both sides of blackboard eraser body, remain back control of dust baffle plate and be close to blackboard panel, with dust collection in dust collecting trough, reach the elimination dust, the purpose that purifies air.Because it is simple and reasonable for structure, low cost of manufacture is promoted the use of so more be suitable in educational circles.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The utility model is done with detailed description below with reference to embodiment (accompanying drawing):
Dust-free black board eraser of the present utility model mainly comprises housing (1), and the blackboard eraser body parts such as (2) that are loaded in the housing are formed; Be provided with dust collecting trough around the blackboard eraser body (2), in the dust collecting trough of the both sides of blackboard eraser body a control of dust baffle plate (3) be installed respectively, the two ends of control of dust baffle plate (3) all are connected with roller (5) by connecting rod (4); Connecting rod (4) is installed in housing up and down in the groove at two ends by hinge (6), one end of connecting rod (4) is installed in the draw-in groove of control of dust baffle plate (3) end, the other end is processed with a bar shaped groove, and the bearing pin that is installed on the roller (5) is inserted in the bar shaped groove of control of dust baffle plate (3).When roller rotates under the blackboard panel effect, can drive control of dust baffle plate (3) and do upper and lower displacement, the dust collection is placed in the dust collecting trough; For the assurance dust can successfully be collected in the dust collecting trough, and prevent the leakage of dust, all be bonded with the strip of paper used for sealing of making by soft material (7) at the cell wall of dust collecting trough and the upper edge of control of dust baffle plate (3).
