Description
Technical field
The utility model is related to blackboard more particularly to it is a kind of can auto-erasing dust-free blackboard.
Background technology
In recent years, many researchs have been carried out to dust-free blackboard both at home and abroad.In some developed countries, more clean and multi-functional
Electronic whiteboard gradually replacing the blackboard that traditional chalk dust is flown upward, become the teaching equipment of school's first choice.But it is existing
Having intelligent blackboard, there is install inconvenient, price costly, it is difficult to popularize, as electronic whiteboard a complete set of equipment needs
Wan Yuan, many places do not have the economic condition for being equipped with this blank.
Invention content
In view of this, the purpose of this utility model be to provide it is a kind of can auto-erasing dust-free blackboard, it is not only of low cost
And it is easy to operate.
The utility model solves above-mentioned technical problem by following technological means：
It is a kind of can auto-erasing dust-free blackboard, include the installing frame of flexible writing panel and the left and right sides, feature exists
In：The flexibility writing panel back side, which is from top to bottom arranged in order, is equipped with support chip, and the support chip cross section is triangle,
So that continuous support chip forms a saw tooth belt, it is square that the opposite side of the installing frame of the left and right sides, which is respectively arranged with path,
The slot of ring shape, the flexibility writing panel head and the tail are in conjunction with the rectangle or annular that are formed and slot path matches, support
The both ends of piece, which are inserted in the slot, allows flexible writing panel to move back and forth in slot；
Top and bottom in the installing frame are separately installed with motor-driven first gear and second gear, and described
The saw tooth belt that the support chip of one gear and second gear respectively at top and bottom is formed is engaged to form gear drive, the installation
Packed wiping case is set below frame, and the flexibility writing panel its writing surface in rotation process is passed through from wiping case, institute
State the blackboard eraser for being equipped in wiping case and being abutted against with flexible writing panel writing surface.
As being further improved for this programme, the flexibility writing panel back side is vertically-mounted to have what is abutted with support chip to erect
Bar, the montant are fixed on installing frame.
As being further improved for this programme, the angle that the inclined-plane of adjacent two support chip is formed is more than 90 °.
As being further improved for this programme, the wiping case is provided with renovating for cleaning chalk dust.
The beneficial effects of the utility model：This programme is the support chip phase of triangle using soft writing panel and cross section
The hardness write can be not only crimped but also met in conjunction with so that writing panel, simultaneously support piece formed each other dentalation with
Gear coordinates the rotation for just realizing writing panel by motor driven gear again, in the wiping of rotation process writing surface and sealing
Blackboard eraser in case rubs, and to realize the purpose of cleaning blackboard, and whole process carries out in seal box,
Chalk dust will not be caused to fly upward, while this programme simple in structure and low in cost, be suitable for each place to operate schools.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described in detail below with reference to attached drawing：
As shown in Figure 1：
It is a kind of can auto-erasing dust-free blackboard, include the installing frame 3 of flexible writing panel 5 and the left and right sides, it is described
5 back side of flexible writing panel, which is from top to bottom arranged in order, is equipped with support chip 4, and 4 cross section of the support chip is triangle so that
Continuous support chip 4 forms a saw tooth belt, and it is rectangle that the opposite side of the installing frame 3 of the left and right sides, which is respectively arranged with path,
Or the slot of annular, the flexibility writing panel (5) is from beginning to end in conjunction with the rectangle or annular formed and slot path matches, support
The both ends of piece 4, which are inserted in the slot, allows flexible writing panel 5 to move back and forth in slot.In the installing frame 3
Top and bottom are separately installed with motor-driven first gear 8 and second gear 6, and the first gear 8 and second gear 6 are divided
The saw tooth belt not formed in the support chip of top and bottom 4 is engaged to form gear drive, and 3 lower section of the installing frame is provided with sealing
Wiping case 2, the flexibility writing panel 5 its writing surface in rotation process passes through from wiping case 2, pacifies in the wiping case 2
Equipped with the blackboard eraser 7 abutted against with 5 writing surface of flexible writing panel.
Preferably, in order to enable motor is more effortless, support chip 4 is provided at both ends with idler wheel, is mounted in slot by idler wheel,
To mitigate the frictional force of support chip 4.
In order to keep the rotation of flexible writing panel 5 convenient, 4 both ends of above-mentioned support chip are designed to that cylinder, cylindrical part are complete
Portion is inserted in slot.
In order to facilitate control, the switch of motor can use wireless remote control or cable switch, press switching motor and start to turn
Dynamic, release then stops, and instructor can arbitrarily adjust the path length that flexible writing panel 5 rotates according to the demand of oneself.
As being further improved for this programme, flexibility writing panel 5 back side is vertically-mounted to be had and is abutted with support chip 4
