Abstract

The present invention relates to an automatic cleaning blackboard, the plane which can turn upwards and downwards one circle. The transmission element is arranged on the frame of a rectangle combined cabinet unit. A power roll shaft is arranged above the frame, and one end of the power roll shaft is connected with an electromotor. A movable roll shaft which is squared and fastened by the lower guide is arranged inside the scrubbing groove which is positioned at the lowest part of the frame. The scrubbing groove is internally provided with two fur brushes and is filled with cleaning liquid. The groove body is assembled with the frame by the adjusting threaded spindle of the two ends of the grove body and the slide way of the cabinet rack. The plane of the blackboard is made to a lantern ring shape by pitting surface black cloth insertion sheet with a front end and a tail end connected with each other. A metal cushion plate is arranged at the inner side clinging to the front side plane between the upper roll shaft and the lower roller shaft inside the plane lantern ring. A manual rope wheel is arranged on the other end of the upper power roll shaft to ensure normal operation under power-on or power-off. The electric blackboard ensures that the teacher no longer stands a-tiptoe or bend waist for writing, ensures that the students in each corner can see the blackboard plane clearly and the dust harm to the teachers and students can also be completely eliminated.

Description

Driven blackboard

Affiliated technical field

The present invention relates to the used a kind of driven blackboard of teaching, training, its plate face can move up and down, as turns over the plate face that circles and just can scrub automatically, as at non-Electric region or its also available manual rope sheave use as usual when having a power failure.

Background technology

The used all types of blackboards of current each universities, middle and primary schools of each town and country, state-of-the-art still is what manufacture with pitted skin glass, this pitted skin Glass blackboard is because the size restrictions plate face that grows tall is not enough, every class is the wipping board face repeatedly, so not only influence teaching and classmate take notes, and more seriously chalk dust is endangering teachers and students' health.

Summary of the invention

For the invention provides, the above-mentioned drawback that overcomes existing blackboard a kind ofly makes assembly with rectangular metal frame, use pitted skin black. the end to end collar shape plate face of making of cloth insertion sheet, its top is that an end is connected with motor, the power roll shaft that the other end is equipped with manual rope sheave is done transmission, the servo-actuated roll shaft of its below levelling guiding tension is to be contained in the below to scrub in the groove, twice hairbrush and cleaning fluid are housed in the groove, scrub groove and framework and be with the adjusting leading screw assembling of slideway on the framework and groove end.Be close to metal liner backing plate of inboard peace of front side board face in the collar of texolite face, driving motor is contained in the driven blackboard on this piece liner plate.

The technical solution adopted for the present invention to solve the technical problems is: run into the method that all can adopt the gluing pressing when fabric width reaches end to end technology inadequately when making collar shape plate face with adhesive plaster, pitted skin can be made in the roller surface in order to increase power roll shaft frictional force; In order to solve at non-Electric region or to use when having a power failure, adopt the other end that manual rope sheave is housed at the power roll shaft; The gentle hard appropriateness of plate face adopts and adorns a liner plate in texolite face collar inner close fitting front panel inboard when guaranteeing writing on the blackboard; In order to make plate face levelling tension, adopt servo-actuated roll shaft to be installed in scrubbing in the groove of below with the below, scrub groove and adopt the leading screw at frame sliding way and cell body two ends to assemble mutually with framework; Install with unlubricated bearing at the two ends of two roll shafts in order to reduce maintenance; Also in cleaning fluid, participate in proper amount of glycol in order in the environment of no heating system, to use; In order to reduce appearance and size motor is contained on the liner plate.The invention has the beneficial effects as follows that can make and be sitting in both sides and classmate far away and all see content on the plate face clearly because the plate face can upwards move to a high position, because the plate face can return, the teacher can repeat to explain lecture contents downwards, the classmate also can perform notes.Also owing to do not need to erase the board, this not only can guarantee teacher's the hours of instruction and the continuity of content, has also thoroughly removed the harm of dust to teachers and students' health again.

Accompanying drawing is the side cutaway view of driven blackboard, among the figure:

1, the servo-actuated roll shaft 5 of rectangle group frame 2, motor 3, pitted skin power roll shaft 4, guiding tension, dress servo-actuated roll shaft, hairbrush and cleaning fluid scrubs groove 6, hairbrush 7, pitted skin black texolite face 8, metal gasket liner plate 9, unlubricated bearing

Embodiment:

By long 2.4 meters, high 1.7 meters (gold ratio) makes group frame 1 with metal bar section; By 0.1 meter of long 2.2 meters (not including axial length) diameter, an end links to each other with motor 2 again, and other end spindle nose lengthening is adorned manual rope sheave, and the surface is the power roll shaft 3 of pitted skin; By 3 specification two end axles the no pitted skin in surface that do not extend, the guiding of fabrication and installation in scrubbing groove strained servo-actuated roll shaft 4 again; By long 2.3 meters, high 0.2 meter, wide 0.12 meter again, scrub groove 5 with the stainless steel material making; In scrubbing groove, be provided with hairbrush 6; Trench bottom stays blowoff valve, and interior dress cleaning fluid, cell body and framework are the adjusting leading screw allotments with slideway on the frame and cell body two ends.Use 2.2 meters of fabric widths again, length be outside two roll shaft gardens the distance 2 times, the pitted skin black cloth insertion sheet that thickness is 2 millimeters is with its end to end collar shape plate face 7 of making; With long identical with plate face fabric width, wide is 1.3 meters again, and thick is 3 millimeters metallic plate, it is propped up filled up 0.1 meter high, is contained in the inboard of being close to the front side board face and makes lining plank 8; Motor is contained on this piece lining plank.Also in order to reduce maintenance at the termination of two roll shafts unlubricated bearing 9; Also to make the bag frame at last with decorative metal.

Claims (2)

1. a plate face can move up and down the driven blackboard that can clean automatically, the plate face that it is characterized in that it is made collar shape with pitted skin black cloth insertion sheet, its driving member is contained on the rectangle group frame, the framework top is the power roll shaft that an end is connected with motor, the servo-actuated roll shaft of below guiding tension, be contained in scrubbing in the groove of below, scrubbing has the twice hairbrush to fill cleaning fluid in the groove, and scrubbing groove and framework is to assemble with the slideway that the cell body two ends are regulated on leading screw and the framework.

2. its feature of driven blackboard as claimed in claim 1 is that also the other end of the power roll shaft of its top is equipped with manual rope sheave, and there is a lining plank inboard of also being close to the front side board face in the collar of texolite face.
