Description
Technical field
This utility model is a kind of cleanable cyclic blackboard, belongs to blackboard apparatus field.
Background technology
Blackboard not refers in particular to the plate face of black, traditional sense is said it be one can be with the plane of repeated writing, plate face is hard, be used for teaching.Make with plank or ground glass etc., can write above with specific writing materials such as chalks.It mostly is black, blackish green, white or ecru.Before word is invented, it has been found that Linesless charcoal can be drawn a picture, some in Europe in the ancient times in grotto it appeared that some mural paintings in ancient times, the crag drawing these mural paintings has been properly termed as blackboard from traditional sense.Ancient Chinese is imparted knowledge to students multiplex a kind of article being referred to as sand table, and with hardwood repeated writing on sandy soil, but because sandy soil are softness, it can not be interpreted as being a kind of blackboard.Middle Ages; it is found that Calx and water are mixed and made into block; write at dark hard article surface by the method being similar to charcoal pencil; to 19th century; people are coated in board surface with pitch-dark; not being etched with protection plank, the Main Function of blackboard is not teaching the most at that time, until mid-term in 19th century, just all over the world, school came into vogue.Blackboard from the earliest spread upon the hard objects surfaces such as plank, cement with blacking, to the water mill glass of the nineties, color coated steel sheet, composite panel .... witness the development step by step of world's educational undertaking, conveyed knowledge for the mankind, universal education, has made distinctions won on the battlefield.
Existing blackboard, use all-in-one-piece, inconvenient when in use, such as needs cleaning blackboard when, owing to being one piece of overall blackboard, for clearance the completing such as also need to just can reuse, having delayed the more time, wasted valuable time on classroom, the speed of labor cleaning's blackboard is slow simultaneously, need the muscle power expended many, and the weak effect of cleaning.
Utility model content
The deficiency existed for prior art, this utility model purpose is to provide a kind of cleanable cyclic blackboard, and to solve the awkward problem proposed in above-mentioned background technology, this utility model is easy to use, it is simple to operation, time-consuming, rapid operation.
To achieve these goals, this utility model is to realize by the following technical solutions: a kind of cleanable cyclic blackboard, including blackboard fixed frame, slide rail and sensor, described blackboard fixed frame be internally provided with blackboard, described blackboard be provided above pulley, described pulley be internally provided with pulley spindle, described blackboard be provided above pulley groove, described slide rail is arranged on the top of blackboard fixed frame, described slide rail be provided above support column, described support column be provided above fixed plate, the lower section of described fixed plate is provided with hydraulic telescopic device, the lower section of described hydraulic telescopic device is provided with cleaning device, described sensor is arranged on the lower section of fixed plate.
Further, described blackboard is provided with two pieces altogether, and two pieces of blackboards are separately mounted to the inside of blackboard fixed frame.
Further, described pulley is provided with eight altogether, and eight pulleys are separately mounted to four corners of two pieces of blackboards.
Further, described hydraulic telescopic device is provided with two altogether, and two hydraulic telescopic devices are separately mounted to the lower section of fixed plate.
Further, described slide rail is provided with two altogether, and two slide rails are separately mounted to above and below blackboard fixed frame.
Further, described hydraulic telescopic device is cylindrical structural.
The beneficial effects of the utility model: a kind of cleanable cyclic blackboard of the present utility model, blackboard is designed as two pieces, on the content record attended class one piece of blackboard wherein, right side only need to be pushed it against one piece of blackboard record is expired when, the blackboard on right side is won over use, sensor will sense the blackboard needing cleaning simultaneously, cleaning device will be withstood on blackboard by hydraulic telescopic device, directly cleared up by slide rail, do not waste any time, also without labor cleaning, cleaning effect is good, improves the service efficiency of time in classroom.
