Description
Technical field
This utility model relates to a kind of automatic dust-reducing blackboard, belongs to teaching aid technical field.
Background technology
In teaching process, blackboard is the Important Platform that student is lectured knowledge by teacher, particularly in the middle and primary schools that ability to accept is poor, blackboard is particularly important, at present, existing blackboard for teaching, the old-fashioned blackboard being all integrally fixed on wall, needing the chalk writing write on manual wipping blackboard after writing, one is that labor intensity is big;Two is to fly dust from flying, pollutes environment, easily causes pneumoconiosis；And as, in middle and primary schools, owing to student's stature is the shortest and the smallest, it is impossible to wipe the chalk writing of higher position on blackboard, it has to by foreign objects such as stooles, add danger, make blackboard in use, bringing more trouble to teacher, student.
Utility model content
For solving the technical problem that prior art exists, this utility model provides a kind of simple in construction, easy to use, effectively reduces dust pollution, the automatic dust-reducing blackboard that labor intensity is low.
nullFor achieving the above object，The technical scheme that this utility model is used is automatic dust-reducing blackboard，Including housing，The both sides of described housing are provided with U-type groove，The top of described housing is provided with upper cover body，Bottom is provided with lower cover，The both sides of described upper cover body and lower cover are provided with bearing block，Support on described bearing block and rotating shaft is installed，Described rotating shaft is positioned at U-type groove，One end of rotating shaft is provided with driving means，And annulus rubber cincture is installed in rotating shaft，Support backing plate it is provided with between described upper cover body and lower cover，Described support backing plate is positioned at the back of annulus rubber cincture writing surface，The opening of described U-type groove is provided with baffle plate，Described U-type groove and baffle plate constitute dust-collecting cavity，It is provided with wiping block in described dust-collecting cavity，Described wiping block is fixed in U-type groove by elastic device，The bottom of described dust-collecting cavity is provided with sweep-up pipe，Connect on sweep-up pipe and have dust exhaust apparatus.
Preferably, described elastic device includes that locating dowel and holddown spring, described locating dowel are fixed on the cell wall of U-type groove, and described holddown spring one end is sleeved in locating dowel, and the other end is fixed on wiping block.
Preferably, described upper cover body is provided with fixed ear base.
Preferably, described driving means includes motor and decelerator.
Compared with prior art, this utility model has following technical effect that this utility model simple in construction, easy to use, use the dust-collecting cavity at opposing seal to carry out wiping person's handwriting, carry out dust removal process in time, effectively reduce dust pollution, and it is substantially reduced the labor intensity of teacher or student, and free from environmental pollution, reduce the sickness rate of pneumoconiosis, thus improve teaching environment, improve the quality of teaching.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
nullSuch as Fig. 1、Shown in Fig. 2，Automatic dust-reducing blackboard，Including housing 1，The both sides of housing 1 are provided with U-type groove 2，The top of housing 1 is provided with upper cover body 3，Bottom is provided with lower cover 4，The both sides of upper cover body 3 and lower cover 4 are provided with bearing block 5，Support on bearing block 5 and rotating shaft 6 is installed，Rotating shaft 6 is positioned at U-type groove 2，One end of rotating shaft 6 is provided with driving means，And annulus rubber cincture 7 is installed in rotating shaft 6，Driving means uses motor 16 and decelerator 17，Support backing plate 8 it is provided with between upper cover body 3 and lower cover 4，Support backing plate 8 and be positioned at the back of annulus rubber cincture 7 writing surface，The opening of U-type groove 2 is provided with baffle plate 9，U-type groove 2 and baffle plate 9 constitute dust-collecting cavity 10，Wiping block 11 it is provided with in dust-collecting cavity 10，Wiping block 11 is fixed in U-type groove 2 by elastic device，The bottom of dust-collecting cavity 10 is provided with sweep-up pipe 12，Connect on sweep-up pipe 12 and have dust exhaust apparatus.
Wherein, elastic device includes locating dowel 13 and holddown spring 14, and locating dowel 13 is fixed on the cell wall of U-type groove 2, and holddown spring 14 one end is sleeved in locating dowel 13, and the other end is fixed on wiping block 11, and upper cover body 3 is provided with fixed ear base 15.
In use, being fixed on the wall by blackboard by fixed ear base, the writing surface back of annulus rubber cincture arranges support backing plate, is used for supporting annulus rubber cincture and conveniently writes.When needs wiping, starting motor, motor-driven rotatable shaft rotates, thus drive annulus rubber cincture to rotate, in rotation process, due to wiping block under the action of the elastic means, pressure is applied to the writing surface of annulus rubber cincture, wiping person's handwriting, the most whole wiping work is all carried out in dust-collecting cavity, opposing seal, the dust that wiping is got off falls, siphoned away in time by sweep-up pipe, good dedusting effect, effectively reduce dust pollution.Blackboard entirety is disassembled and used demountable structure, conveniently removes and installs, and can change wiping block at any time, uses convenient.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, in the range of all should wrapping in this utility model.
