It has solved the long -pending little problem that can't remain the writing on the blackboard of blackboard face, and convenient to use provides convenience for the teaching.
Description
Technical field
The utility model relates to a kind of blackboard, especially a kind of rotatable blackboard.
Background technology
Since two a century, blackboard from the earliest with blacking spread upon the hard objects such as plank, cement surface, to water mill glass, color coated steel sheet, composite panel etc., the development step by step of educational undertaking of blackboard witness, for the mankind convey knowledge, spread education and made distinctions won on the battlefield.In teaching, the reservation of writing on the blackboard content is a very actual problem, because the space of a whole page size of blackboard itself is limited, and time teacher's writing on the blackboard content is more usually, a blackboard is difficult to all the elements to record, and therefore at this time original writing on the blackboard content blackboard eraser can only be wiped, cannot by reservation complete for writing on the blackboard, cannot consult when needs are inquired about previous contents or explain time like this, cause the inconvenience of teaching.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rotatable blackboard, and it rotates use by Multiface blackboard being formed polygonal prism cylinder, thus solves the little problem that cannot retain writing on the blackboard of blackboard area.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of rotatable blackboard, it is characterized in that: comprise rotating shaft, spoke frame, blackboard frame, blackboard, both sides rotary shaft rack, decelerator, motor, worm gear and worm screw, described rotating shaft is horizontally disposed with and two ends rotation is arranged on the rotary shaft rack of both sides, spoke frame to be fixed in rotating shaft perpendicular to rotating shaft and some spoke framves along the equidistantly distribution of rotating shaft circumference, some blackboard frame are fixed on two adjacent groups spoke frame, blackboard to be fixed in blackboard frame and some blackboards composition polygonal prism cylinder, described worm gear is fixed on rotating shaft one end, worm screw is arranged on and engages each other with worm gear on the downside of worm gear and worm screw one end is connected with decelerator and is driven by decelerator, decelerator is driven by motor.
Further, described motor adopts stepper motor.
Further, described rotatable blackboard also comprises switch and control cabinet, and switch to be fixed on the body of wall of classroom and to be connected with control cabinet, and be provided with time-delay relay in control cabinet, time-delay relay normal open switch is connected with motor.
Further, described rotatable blackboard is also provided with electromagnet, electromagnet is fixed on body of wall by electromagnet stent, when a blackboard of the polygonal prism cylinder that blackboard is formed turns to body of wall overlapping positions time, electromagnet is just positioned at a spoke frame side, and electromagnet is connected with the normally closed switch of time-delay relay.
Further, described polygonal prism cylinder is six prisms.
The utility model compared with prior art, have the following advantages and effect: Multiface blackboard is formed polygonal prism cylinder by blackboard frame, spoke frame and rotating shaft by rotatable blackboard, thus rotate use, solve the little problem that cannot retain writing on the blackboard of blackboard area, for teaching provides conveniently, drive worm and worm wheel to control blackboard additionally by motor to rotate, easy to operate, easy to use.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of rotatable blackboard of the present utility model.
Fig. 2 is the side view of rotatable blackboard of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
As shown in the figures 1 and 2, rotatable blackboard of the present utility model comprises rotating shaft 1, spoke frame 2, blackboard frame 3, blackboard 4, both sides rotary shaft rack 5, decelerator 6, motor 7, worm gear 8 and worm screw 9, rotating shaft 1 is horizontally disposed with and two ends rotation is arranged on both sides rotary shaft rack 5, spoke frame 2 to be fixed in rotating shaft 1 perpendicular to rotating shaft 1 and some spoke framves 2 along the equidistantly distribution of rotating shaft 1 circumference, some blackboard frame 3 are fixed on two adjacent groups spoke frame 2, blackboard 4 is fixed in blackboard frame 3 and some blackboards 4 form polygonal prism cylinder, worm gear 8 is fixed on rotating shaft 1 one end, worm screw 9 is arranged on and engages each other with worm gear 8 on the downside of worm gear 8 and worm screw 9 one end is connected with decelerator 6 and is driven by decelerator 6, decelerator 6 is driven by motor 7.Wherein, motor 7 adopts stepper motor, and like this when motor 7 drives blackboard 4 to turn to assigned address time, motor can stop at once at assigned address.
Rotatable blackboard also comprises switch 10 and control cabinet 11, and switch 10 to be fixed on the body of wall of classroom and to be connected with control cabinet 11, and be provided with time-delay relay in control cabinet 11, time-delay relay normal open switch is connected with motor 7.Rotatable blackboard is also provided with electromagnet 12, electromagnet 12 is fixed on body of wall by electromagnet stent 13, when a blackboard of the polygonal prism cylinder that blackboard 4 is formed turns to body of wall overlapping positions time, electromagnet 12 is just positioned at spoke frame 2 side, and electromagnet 12 is connected with the normally closed switch of time-delay relay.Like this when a blackboard writing on the blackboard is write full time, teacher only needs Push switch 10, time-delay relay energising work, normally closed switch disconnects and controls electromagnet 12 power-off, simultaneously normal open switch closes motor 7 and starts working and drive blackboard to start to rotate and change next block blackboard, it is that motor 7 just drives next block blackboard to turn to the time overlapped with body of wall that time-delay relay arranges delay time, when rotateing in place, time-delay relay normal open switch is replied and is disconnected, motor 7 quits work, simultaneously time-delay relay normally closed switch is closed makes electromagnet 12 be energized to carry out absorption to spoke frame 2 to locate, place blackboard in use to rock.Wherein, polygonal prism cylinder adopts six prisms, and such integrated cost and actual service condition are considered, six prisms of six blackboard compositions are the most suitable.
Above content described in this description is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of the utility model description or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
