The horizontal wheel 16 on upper rail 1 in example is mainly the frictional force eliminating vertical wheel 17 and receiving, and vertical wheel primarily serves traction device or so
The mobile function of erasing the board, lower railway 18 are also such.The wheel on upper and lower both sides is ined succession main shaft 2, and main shaft is located at blackboard front,
Play the role of the sub- driving device of match wheel to each component is connected.
As shown in Figure 1,2 and 3, in the present embodiment, main shaft shell 3 has primarily served connection handle 20 and scrubbing brush frame 4
Effect.2 surrounding of main shaft is arranged in main shaft shell 3, and the both ends of main shaft shell 3 connect firmly main shaft 2, set between main shaft shell 3 and main shaft 2
Spacing is set, the handle shell 6 for handle 20 to be arranged is arranged in evagination in main shaft shell 3, passes through telescopic rod on handle shell 6
7 setting handle covers 11, one end of telescopic rod 7 connect firmly handle shell 6, and the other end of telescopic rod 7 connects firmly handle cover 11.
As shown in figure 3, handle 20 is in " U " font, handle 20 is inserted into handle shell 6 and the both ends of handle 20 connect one
Vertical pole 15, vertical pole 15 are arranged in the spacing between main shaft shell 3 and main shaft 2.
In the present embodiment, handle 20 is connected to vertical pole 15 in main shaft shell 3, and vertical pole 15 is connected in main shaft shell
Cross bar 13, cross bar 13 are connected to scrubbing brush frame 4, so three constitutes a system.When hand holds handle 20, handle is firmly squeezed
Handle cover 11 on hand, handle cover 11 will compress telescopic rod 7, and the shortening of telescopic rod 7 pulls vertical pole 15 to 20 direction of handle
To drive cross bar 13, because being connected with scrubbing brush frame 4, scrubbing brush frame 4 is also pulled to leave blackboard 12, plate cross bar 13
There are gaps between 12 plate face of brush holder 4 and blackboard, when encountering the blackboard writing on the blackboard that cannot be brushed off, can skip, therefore accomplish
The function that optional blackboard region erases the board；The function of this system is exactly that selectable region erases the board.
As shown in Figure 1, the section of scrubbing brush frame 4 is arc-shaped, scrubbing brush frame 4 is parallel to the intrados of the setting of main shaft 2 and scrubbing brush frame 4
It is directed toward main shaft 2, the length of scrubbing brush frame 4 is equal to the width of blackboard；Scrubbing brush frame 4 passes through at least one connection component 10 and main shaft shell
3 connections；The present embodiment is illustrated by taking three connection components 10 as an example.
As shown in Figures 2 and 3, connection component 10 includes 13, pressure springs 21 of a cross bar and a sleeve 22, and sleeve 22 hangs down
Directly it is arranged on the lateral surface of main shaft shell 3 and sleeve 22 is directed toward scrubbing brush frame 4, cross bar 13 is inserted into sleeve 22, and 13 one end of cross bar is solid
Join vertical pole 15,13 other end of cross bar connects firmly the intrados of scrubbing brush frame 4,21 sets of pressure spring on cross bar 13, one end of pressure spring 21 connects
The other end of scrubbing brush frame 4, pressure spring 21 connects sleeve 22；Sponge is set along 4 length direction of scrubbing brush frame on the extrados of scrubbing brush frame 4
Scrubbing brush.Sponge plate brush is by being fastened on the extrados of scrubbing brush frame 4.Sponge plate brush and scrubbing brush frame 4 can be with Simple detachables, clearly
It washes.
In the present embodiment, when handle cover 11 does not have applied force, pressure spring 21 is in tensional state, and scrubbing brush frame 4 is tightly attached to
12 surface of blackboard, when handle 20 is held with a firm grip, when 11 applied force of handle cover, handle cover 11 will compress telescopic rod 7, and telescopic rod 7 contracts
Short to pull to 20 direction of handle by vertical pole 15 to drive cross bar 13, cross bar 13 with scrubbing brush frame 4 because be connected, scrubbing brush
Frame 4 is also pulled to leave blackboard 12, and there are gaps between 12 plate face of scrubbing brush frame 4 and blackboard.But do not have when on handle cover 11
When applied force, pressure spring 21 is stretched, and scrubbing brush frame 4 is fitted in 12 surface of blackboard.
As illustrated in fig. 1 and 2, dust collecting box 9 be arranged main shaft 2 bottom end and dust collecting box 9 be located at scrubbing brush frame 4 just under
Side is for collecting powder ash.
Blackboard 12 is stretched out at the both ends of upper rail 1 and lower railway 18 in the present embodiment, and the two of upper rail 1 and lower railway 18
12 end 20cm of blackboard is stretched out at end.The present apparatus can be placed in blackboard both sides and is not take up by the design of this technical characteristic
The usable floor area of blackboard, maximally utilizes space.
Device for blackboard eraser further includes two dust baffles 5, and two dust baffles 5 are symmetrical along 4 length direction of scrubbing brush frame respectively
It is arranged on the two sides of scrubbing brush frame 4, the bottom end of two dust baffles 5 is all connected with dust collecting box 9.Dust baffle is transported in device
The dust for the generation that erases the board can be kept off in dust baffle completely when dynamic, baffle connects with dust collecting box.
Handle shell 6 need to only be held when needing to wipe monolith blackboard writing on the blackboard to draw its left and right, so that it may easily will be black
Blackboard eraser is good, can remove the sponge plate brush on scrubbing brush frame when needing to wash blackboard and be put on again with water-soaked, then by blackboard or so
It draws with regard to blackboard capable of washing.
When encountering the blackboard writing on the blackboard that cannot be brushed off, when hand holds handle 20, the firmly handle cover 11 in squeeze handles,
Hand lid 11 will compress telescopic rod 7, and telescopic rod 7 shortens to be pulled to drive cross bar 13 by vertical pole 15 to 20 direction of handle,
Because being connected with scrubbing brush frame 4, scrubbing brush frame 4 is also pulled to leave blackboard 12, scrubbing brush frame 4 and 12 plate face of blackboard cross bar 13
Between there are gaps, can skip, therefore accomplished the function that optional blackboard region erases the board.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not
It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define
Under the premise of, it can various changes can be made in the form and details to it.
