Shown in figure: 1, base plate 2, support frame 3, lead 4, adjustable shelf 5, stage clip 6, web plate 7, blackboard eraser holder 8, rotating shaft 9, shake the hand 10, driving wheel 101, point 102, arc convex 11, stressed plate 12, hole 13, blackboard eraser 14, limited block 15, dust cover 16, powder accommodating groove.
Detailed description of the invention
Below by drawings and Examples, the utility model is further elaborated.
As shown in Figure 1: a kind of blackboard eraser dedusting beater, comprises base plate 1. Support frame 2 is installed on base plate 1, and the inside that is positioned at support frame 2 on base plate 1 is provided with lead 3. Adjustable shelf 4 is installed on lead 3, and adjustable shelf 4 can be up and down along lead 3. Stage clip 5 is installed on lead 3 between adjustable shelf 4 and bottom. The top of adjustable shelf 4 is provided with web plate 6, and the top of support frame 2 is provided with blackboard eraser holder 7, and blackboard eraser holder 7 is oppositely arranged up and down with web plate 6. Blackboard eraser dedusting beater also comprises that also at a time moment pops up so that the energy storage and energy release mechanism that web plate 6 contacted with 13 moments of blackboard eraser for pressing adjustable shelf 4 downwards. The below that is positioned at web plate 6 on base plate 1 is provided with powder accommodating groove 16, and the arranged outside of support frame 2 has dust cover 15.
Energy storage and energy release mechanism comprises the rotating shaft 8 being supported on support frame 2, one end of rotating shaft 8 is stretched out support frame 2 and is provided with and shakes the hand 9, driving wheel 10 is installed in rotating shaft 8, driving wheel 10 has two points 101 that relatively arrange outwardly, the below of driving wheel 10 has the stressed plate 11 being connected with adjustable shelf 4, a side that is positioned at rotating shaft 8 on stressed plate 11 on vertical direction is provided with the hole 12 that screws in, screws out for the point 101 on driving wheel 10, and the radius of turn of driving wheel 10 is greater than rotating shaft 8 to the vertical range between stressed plate 11.
The protrusion direction respectively between the middle part to two of driving wheel 10 point 101 with 102, two arc convex 102 of arc convex is contrary. So design, can reduce the frictional force of driving wheel 10 in the time pressing down adjustable shelf 4 and between adjustable shelf 4 greatly, guarantees that driving wheel 10 rotates stably, thereby greatly reduces and rotate the 9 o'clock required power of shaking the hand, and operates more laborsaving. Driving wheel 10 and stressed plate 11 have two groups, lay respectively at the both sides of adjustable shelf 4. So design, adjustable shelf 4 both sides stress balances, thus guarantee that adjustable shelf 4 declines after stressed stably.
In addition, blackboard eraser holder 7 is made up of clamping plate and tightening knob two parts, and clamping plate and tightening knob are oppositely arranged. When use, blackboard eraser 13 is pressed on clamping plate, then rotates tightening knob, make the head end of tightening knob withstand blackboard eraser 13, fix blackboard eraser 13 with this. The top of guide post 3 is provided with limited block 14, with this, adjustable shelf is limited on guide post 3 up and down.
The utility model blackboard eraser 13 processor operation principles:
When use, first blackboard eraser for clearance 13 is fixed in blackboard eraser holder 7, then rotate and shake the hand 9, rotate by the 9 drive driving wheels 10 of shaking the hand, driving wheel 10 withstands stressed plate 11 by the point 101 on it and presses adjustable shelf 4 downwards in rotation, makes adjustable shelf 4 movable along guide post downwards, in this process, stage clip is gradually reduced, and is a thermal energy storage process, specifically refers to accompanying drawing 2; When driving wheel 10 turns to a certain position, when namely point 101 is screwed in the hole 12 on stressed plate 11, because stressed plate 11 is subject to coming from the pressure pop-off of driving wheel 10, adjustable shelf 4 can be under the resilience of stage clip pops up along guide post moment, realize an exoergic process, specifically refer to accompanying drawing 2. In the process that adjustable shelf 4 popped up in moment, web plate 6 can fiercely be patted blackboard eraser 13. The 9 constantly shakes of shaking the hand, adjustable shelf 4 will be constantly up and down, simultaneously web plate 6 is patted blackboard eraser 13 repeatedly, with this to the blackboard eraser 13 cleaning effect of getting up. After being patted, most powder can drop in powder accommodating groove 16 through the hole 12 of web plate 6, and another fraction can be diffused in air, is finally attached on dust cover 15.
The utility model blackboard eraser dedusting beater is exclusively used in the dust that cleaning stays on blackboard eraser 13, easy to use and can be to environment.
The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff can, not departing from the scope of this utility model thought, carry out various change and amendment completely. The technical scope of this utility model is not limited to the content on description, must determine according to claim scope the scope of its protection.
