Description
Technical field
The utility model relates to the blackboard in teaching aid, especially a kind of included wiping function blackboard movable up and down.
Background technique
Blackboard movable up and down is a kind of common teaching aid, and traditional blackboard movable up and down wipes chalk using traditional blackboard eraser
Word, can generate a large amount of dust, and wiping speed is slow and can generate injury to the teachers and students close to blackboard, low efficiency, not environmentally.
A kind of blackboard is disclosed in Chinese utility model patent CN201621339256.6, the blackboard is by frame, first
Blackboard surface, the second blackboard surface, controller and wiping arrangement composition, frame are rectangular configuration, and frame is installed on the metope in classroom, the
The both ends of one blackboard surface and the second blackboard surface are slidably connected on the inside of rectangular configuration, and the first blackboard surface and the feel of the second blackboard surface can
To move up and down along rectangular configuration inner wall two sides, the first blackboard surface is located at the front of the second blackboard and the first blackboard surface and second black
Plate face is parallel, is respectively equipped with two days described in two chains in the two sides on the top of the first blackboard surface and fixes respectively across lifting device
In the second blackboard surface top end face two sides, the blackboard is equipped with rack gear in the outside at frame both ends, and rack gear has two to set vertically respectively
It sets and mentions the lateral wall at both ends in frame, wiping arrangement is installed on the rack gear.The patent the problem is that: the patented technology
The lifting device of blackboard is used as execution unit using chain in scheme, and noise is big when work, and the mechanism is open architecture, without opening
Tight device can generate two sides unbalance stress when encountering uneven power and acting on blackboard surface and cause chain tripping, so it is stuck
In sliding slot, the Wiping mechanism is attached on frame by rack gear, and by climbing device, electric hydaulic telescopic rod and wiping arrangement
Composition, by the biggish shearing force of electric hydaulic telescopic rod receiving known to the structure and positional relationship, and electric hydaulic telescopic rod
It is mainly subject to the component of axial compressive force, therefore the structure will greatly shorten electric hydaulic telescopic rod service life, climb simultaneously
Rise device and wiping arrangement structure be more complex, routinely material calculate its weight will be larger, and the wiping arrangement need to complete two
The wiping of blackboard surface, therefore it has biggish length that can thus generate torque effect to frame in the direction perpendicular to blackboard surface,
Because the traditional approach on the fixed wall of frame is swell fixture, if there is biggish power acts on frame, it is likely that by frame
It is pulled out from metope, causes security risk.
Utility model content
To overcome above-mentioned prior art defect, the utility model provides a kind of included wiping function blackboard movable up and down.
Used by the utility model the specific technical proposal is:
A kind of blackboard movable up and down of included wiping function, the blackboard of the included wiping function includes frame, outer blackboard, interior black
Plate, automatic cleaner and the controller for being fixed on frame side-lower, a kind of blackboard movable up and down frame of included wiping function
For rectangular configuration, frame is installed on the metope in classroom, and the both ends of outer blackboard and interior blackboard are slidably connected on the inside of rectangular configuration,
Outer blackboard and interior blackboard can be moved up and down along rectangular configuration inner wall two sides, outer blackboard be located at the front of interior blackboard and outer blackboard with
Interior blackboard is parallel, and synchronous belt is respectively equipped on the inside of the frame two, and two inside top of frame and bottom are respectively fixed with together
Belt wheel and synchronous belt tension device are walked, the top and bottom in two outside of the outer blackboard and interior blackboard are respectively fixed with guiding dress
It sets, the guiding device is fixed together with the synchronous belt, and the wiping arrangement includes interior wiping arrangement and outer wiping arrangement,
The interior wiping arrangement is fixed at the top of outer blackboard inner face, and the outer wiping arrangement is fixed on the outer Middle face of frame, the wiping
Device includes four-bar mechanism, the wiping module being fixed on four-bar mechanism and power unit.
Synchronous belt has the advantages that as execution unit
(1) transmission is accurate, and when work is fricton-tight, has constant transmission ratio；
(2) stable drive, has buffering, damping capacity, and noise is low；
(3) transmission efficiency is high, and up to 0.98, energy-saving effect is obvious；
(4) maintenance is convenient, is not required to lubricate, maintenance cost is low；
(5) it is transmitted relative to V-type band, pretightning force is smaller, and institute is loaded small on axis and bearing；
It can be seen that using synchronous belt as execution unit in terms of the maintenance of teaching environment and teaching aid for classroom
It is more suitable, simultaneously because using tensioning apparatus, the phenomenon that the certain pretightning force of synchronous belt can be given, tripping will not be generated.
The synchronous belt tension device is made of screw rod and swivel nut, and the screw rod is actively connected on the fixing axle of belt pulley
On, the swivel nut is fixed on inside frame two sides.This maintenance cost simple and practical in structure is low.
The guiding device by be vertically directed in the front-back direction wheel, left and right directions be vertically directed wheel and U-shaped pedestal, it is described
U-shaped pedestal is separately fixed at the top and bottom in two outside of outer blackboard and interior blackboard, and the wheel that is vertically directed in the front-back direction is lived
The side plate of U-shaped pedestal is arranged the bottom of close in the dynamic bottom edge that U-shaped pedestal is arranged in, the wheel activity that is vertically directed of the left and right directions
The edge of plate.
Using guiding device, blackboard can be made smoothly to slide in frame.
The wiping arrangement is made of outrigger, wiping module, four-bar mechanism and power unit, the four-bar mechanism successively by
Strut C, bracket, strut A and strut B composition, strut B are movably fixed on the inside of outrigger or on the inside of outer blackboard, the wiping module
It is fixed on bracket, inside or outer blackboard inside, the electrical source of power are fixed on the inside of outrigger outside for the bracket slide setting
Or it is rigidly connected on the inside of outer blackboard and with strut B.
This structure within 10 millimeters, can greatly reduce wiping arrangement perpendicular to the control of the operating range of blackboard surface
For wiping arrangement in the length perpendicular to blackboard surface direction, structure is more compact, while four-bar mechanism is traditional reliable execution
Structure, therefore the mechanism is relatively reliable.
The Wiping mechanism is made of scraper plate, collodion head and sink, and the scraper plate and sink are fixed on the bracket, institute
Collodion head is stated to be wrapped on sink.
The faying face of the sink and collodion head, which is equipped with above micropore and end, is equipped with water injection hole.
Preferably, the collodion head is polyvinyl alcohol collodion head.
Using the wiping of moist environment, dustless, while collodion can be achieved the purpose that under the premise of not increasing dust exhaust apparatus
Head is disassembly, when need it is clear in collodion head when, can be removed to install after flushing can use in the original location, easy to operate.
The good effect of the utility model is: realizing Automatic erasing blackboard, blackboard is gone up and down without sideslip stuck phenomenon, blackboard
Lifting wiping low noise is dustless, and structure is simpler, and wiping effect is more preferable.
