Compared with the prior art, the automatic cleaning spliced blackboard has the beneficial effects that manual blackboard scribbling and wiping can be replaced, and the automatic blackboard cleaning action is finished; the device is simple and can be obtained through refitting on an existing blackboard; and cleaning and using can be conducted at the same time, and normal usage of users is not affected.
Description
Technical field
The invention belongs to realia field, relate to a kind of blackboard, be related specifically to the automatic cleaning in a kind of pair of use face
Assembled blackboard.
Background technology
Blackboard is the realia of a kind of classics, and teacher can write in the above and learn for student viewing.At present in school
The Painting and writing tool that the blackboard of 90 percent uses is chalk, and remaining major part uses free ink pen.For chalk, teacher is being coated with
When erasing the board, easily cause dust, and for it is frequently necessary to be in the teacher of this dust operated within range, can make healthy
Become the biggest impact.For some dust-free chalks or free ink pen, even without the problem of dust, but it is more also to take teacher
Time goes to clear up monoblock blackboard, and particularly in university, usual blackboard is upper and lower two pieces and is used alternatingly, and embrocates workload bigger.
Therefore, it is necessary to provide the technical scheme improved, to solve technical problem present in prior art.
Summary of the invention
It is an object of the invention to, it is provided that a kind of assembled blackboard that can clean simultaneously and use, there is simple in construction, make
Use convenient advantage.
In order to achieve the above object, the invention provides a kind of pair of use face cleans assembled blackboard automatically, including:
Main board face, including a plurality of lath, parallel between described each lath, seamless touch between adjacent described parallel strip
Touch;Wherein said lath includes use face, and the tow sides of lath are provided with described use face;
Driving means, including drive link, driving handle and the connecting rod equal with described lath quantity;Described connecting rod
Including driving gear and connecting the swingle of described driving gear and corresponding lath;Described each driving gear all with described drive link
Occlusion, described driving handle is connected with drive link;
Outer frame body, including operating room with embrocate room, described driving handle, drive link and drive gear to be arranged at described behaviour
Make indoor;The described room of embrocating one side offers plate face and installs window, and described main board face is fixedly mounted on described plate face and installs window
On mouth, be positioned at described in embrocate chamber interior and be additionally provided with cleaning shower nozzle, described cleaning shower nozzle installs window top towards plate face.
During use, user can carry out picture on the use face towards outside and write action, when needs are embrocated, and Ke Yizhuan
Dynamic driving handle, driving handle drives drive link, and due to drive link and each driving engaged gears, the motion of drive link will drive
Drive pinion rotation, drive gear thus drive and rotate with himself fixing swingle, and swingle and lath fix, this
Time the upset entrance of this use face embrocate chamber interior, and be originally positioned at and embrocate the use face of chamber interior and produce, user enters the most altogether
Action write by row picture.
When the use face needing cleaning rotates into and embrocates chamber interior, open and clean shower nozzle, clean shower nozzle by clean water
Body is sprayed at lath and uses top, face, and prolongation in time, clean water body to flow through each lath from top to bottom, thus reaches to clean
The purpose in use face, whole main board face.
Preferably, the shape size of described each lath is the most identical.It is further preferable that the quantity of described lath is 10, wide
Degree is 20 centimetres.Same it is further preferable that the quantity of described lath is 20, width is 10 centimetres.The whole height of blackboard is 2
Rice is more suitable, the wide or flat discomfort the most easily affecting user and beholder of mistake.
Preferably, one end of described lath is installed with described swingle, and the other end is installed with location abutment extending, position
Window edge is installed in described plate face and is provided with the fixed card slot for described location abutment extending overlap joint.Such scheme is in order to ensure plate
Bar life-time service will not rotate the situation of axle offset.The two ends being positioned at lath are provided with hard point, one end therein by
Swingle load, the other end is coordinated load from positioning abutment extending with fixed card slot.During installation, location abutment extending is goed deep into inside fixed card slot
To obtain location, owing to fixed card slot will not apply grip force to location abutment extending, the most do not affect lath normally rotates use.
Preferably, described swingle length is longer than lath, and described lath is fixed on the middle part of swingle, is positioned at described plate face
Window edge is installed and is provided with the fixed card slot overlapped for described swingle.The design concept of this programme is to include two for lath
Hold at interior overall offer hard point.Lath is longer, and generally between 2~5 meters, therefore unilateral fixing easily causes lath to rotate
Axle offset or bend, make lath be integrally attached on swingle to make each point stress equal, and middle part will not be occurred to cave in
Phenomenon.
Preferably, the quantity of described cleaning shower nozzle is 2~10, may be contained within described in embrocate ceiling portion.Due to main board
Face is longer, and less cleaning shower nozzle is difficult to clean comprehensively.Cleaning shower nozzle is installed on and embrocates ceiling portion simultaneously, can be the most logical
Cross gravity and increase water body pressure.
Preferably, described lath includes long front, long reverse side, the first long side surface and the second long side surface, and described use face is divided
It is not arranged on described long front and long reverse side, is positioned on described first long side surface and the second long side surface and is provided with elastic packing
Bar.When being positioned at the use face embrocating chamber interior and cleaning, water body easily gap leakage between lath and lath, on using
When stating scheme, it is ensured that the normal use in outside use face, make inside and outside be relatively isolated, be independent of each other.
Compared with prior art, the beneficial effects of the present invention is:
Can replace manually being coated with and erase the board, complete the automatic cleaning action of blackboard;Device is simple, can be entered by existing blackboard
Row repacking obtains;Clean and use and can carry out simultaneously, do not affect the normal use of user.
