Abstract
The utility model relates to an electric blackboard eraser, which belongs to the technical field of the group of blackboard or stone board cleaning devices with chalk dust absorbing devices of the subclass of writing or drawing articles and auxiliary writing or drawing articles in the class of writing or drawing instruments and office articles under the subsection of printing in the section of operation and transportation according to the International Patent Classification (IPC). The serial number is B43L21/02. The electric blackboard eraser is composed of conducting wires, a control button, a blackboard, a spare device, a blackboard eraser, a rod-changing mechanism, a telescopic mechanism, a spring, a control box, a speed changer and a motor. The electric blackboard eraser is characterized in that the eraser is connected with the rod-changing mechanism which is connected with the telescopic mechanism; the telescopic mechanism is connected with the speed changer. The utility model is an electric blackboard eraser with practical value.
Description
The utility model relates to electric blackboard eraser.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, the big class of office appliance, write or drawing article, the assistant product group of writing or draw has the blackboard of sucking chalk powder device or the cleaning device technical group field of slabstone.Be numbered B43L 21/02.
At present, the technology about the cleaning device of blackboard that the sucking chalk powder device is arranged or slabstone existing and that once had was all done very fruitful effort to the demand of electric blackboard eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Gu Zhengwu, Granted publication number is CN2243398Y, China Patent No. (ZL) is: No. 95221145.9 utility model title is the utility model patent of " drum-type dust-absorbing blackboard brush ", the technical scheme that is adopted.Cleaning device technical elements at blackboard that the sucking chalk powder device is arranged or slabstone is a routine of great value invention, and it has solved problem how to use the drum-type dust-absorbing blackboard brush effectively.But still have some deficits, it also is difficult to solution and how utilizes cheap motor to solve the problem that manually erases the board.
The purpose of this utility model is to provide a kind of electric blackboard eraser.How to utilize cheap motor to solve the problem that manually erases the board to solve.
The purpose of this utility model is achieved in that this utility model electric blackboard eraser.Mainly constitute by lead, control button, blackboard, stand-by provision, blackboard eraser, change linkage, telescoping mechanism, spring, control cabinet, speed changer, motor.Its major part motor, lead, control button are by selecting for use on the market.Become linkage, telescoping mechanism aluminum alloy materials fine finishining manufacturing.Speed changer is made with No. 45 steels.The utility model main body is made of blackboard and device for blackboard eraser, blackboard eraser is connected with the change linkage, become linkage and be connected with telescoping mechanism, the telescoping mechanism end is connected with spring, and spring is connected on the speed changer, speed changer is connected on the motor by motor shaft, motor, speed changer all are encapsulated in the control cabinet, and blackboard eraser has stand-by provision, the same blackboard eraser of its structure, there is control button in the blackboard lower left corner, and control button is linked control cabinet by lead.So just realized the purpose of this utility model.
The utility model has been compared three advantages and improvement with the original blackboard that the sucking chalk powder device is arranged or the cleaning device technology of slabstone;
The first, because the utility model has designed the change linkage in technical scheme, solved a vertical problem of wiping of blackboard eraser all over full blackboard surface;
The second, because the utility model has designed telescoping mechanism in technical scheme, solved the problem that blackboard eraser is laterally wiped time blackboard surface;
The 3rd, because the utility model has designed standby mechanism in technical scheme, solved a mechanism and gone bad the problem that another mechanism uses immediately.How to utilize cheap motor to solve the problem that manually erases the board thereby just can more effectively solve.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the sectional structure schematic diagram of the utility model electric blackboard eraser;
Fig. 2 is the stand-by provision structural representation of the utility model electric blackboard eraser;
The numbering of parts explanation in the schematic diagram: 1 lead, 2 control buttons, 3 blackboards, 4 stand-by provisions, 5 blackboard erasers 6 become linkage 7 telescoping mechanisms 8 springs 9 control cabinets 10 speed changers 11 motors
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, the utility model electric blackboard eraser.Mainly constitute by lead (1), control button (2), blackboard (3), stand-by provision (4), blackboard eraser (5), change linkage (6), telescoping mechanism (7), spring (8), control cabinet (9), speed changer (10), motor (11).Its major part motor (11), lead (1), control button (2) are by selecting for use on the market.Become linkage (6), telescoping mechanism (7) aluminum alloy materials fine finishining manufacturing.Speed changer (10) is made with No. 45 steels.The utility model main body is made of blackboard (3) and device for blackboard eraser, blackboard eraser (6) is connected with and becomes linkage (6), become linkage (6) and be connected with telescoping mechanism (7), telescoping mechanism (7) end is connected with spring (8), spring (8) is connected on the speed changer (10), and speed changer (10) is connected on the motor (11) by motor shaft, and motor (11), speed changer (10) all are encapsulated in control cabinet (9) lining, blackboard eraser (5) has stand-by provision (4), the same blackboard eraser of its structure (5); There is control button (2) in blackboard (3) lower left corner, and control button (2) is linked control cabinet (9) by lead (1).So just realized the purpose of this utility model.How to utilize cheap motor to solve the problem that manually erases the board thereby just can solve.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in use, if press control button (2), motor (10) rotates, drive telescoping mechanism (7) by speed changer (10), telescoping mechanism (7) drive to become linkage (6), becomes linkage (6) and drives blackboard eraser (6) and just realized the problem of powered brush blackboard, and stand-by provision (4) is in order to prevent a device and to break down and adding.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with the aluminium alloy, utilize the basic equipment of machined factory, take assembling to produce by batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
