Abstract
The utility model relates to a fast cleaning blackboard eraser, which consists of a slide bar, a handrail, a separating plate, a main plate, a handle, a roller and a hairbrush. Because the separating plate is designed in the technical proposal, the utility model can erase the blackboard in large area; and the roller is designed in the technical proposal, the utility model saves labor in erasing the blackboard. The blackboard eraser is characterized in that: one end of the right angular surface of the separating plate is embedded and arranged on the side of the two ends of the main plate; the bearing of the roller is arranged fixedly at the front end of the slide bar; the handrail is welded to the upper end of the slide bar. Therefore, the utility model has an application value very much.
Description
(1) technical field:
The utility model relates to fast clean blackboard eraser.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance, and the big class of office appliance is write or drawing article, the assistant product group of writing or draw, the cleaning device technical group field of blackboard or slabstone.
(2) background technology:
At present, the technology about the cleaning device of blackboard or slabstone existing and that once had was all done very fruitful effort to the demand of fast clean blackboard eraser, also once designed many outstanding technical schemes.As being declared by Chen Hao of the Decree of Patent Office of China on May 15th, 1998, China Patent No. (ZL) is: No. 98237615.4 utility model title is the utility model patent of " no dust blackboard eraser ", the technical scheme that is adopted.Aspect the clear great device technique of blackboard or slabstone be a routine of great value invention, the problem that it has solved effectively.But still have some deficits, the blackboard eraser area was little before its also be difficult to solve, problem that can not very fast wiping word.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of fast great blackboard eraser.Little with blackboard eraser area before solving, problem that can not very fast wiping word.
The purpose of this utility model is achieved in that the fast clean blackboard eraser of this utility model.Mainly constitute by slide bar, handrail, branch plate, mainboard, handle, roller, hairbrush.Its roller, hairbrush are by selecting for use on the market.Its slide bar is " " shape, uses the steel material, through rolling processing and manufacturing.Its handrail is a shape, uses the steel material, through rolling processing and manufacturing.Its branch plate, mainboard are shapes, use wooden material, through the planing operation manufacturing.Its handle is " " shape, uses the steel material, through rolling processing and manufacturing.Handrail adopts welding method to be installed in the upper end position of slide bar, constitutes integrative-structure, and function has been supporting role.Handle adopts the screw fixing means to be installed in the surperficial middle position of mainboard, constitutes fixed structure, and function has been the whole red blackboard eraser effect of control.Roller adopts the bearing fixing method to be installed in the front position of slide bar, constitutes integrative-structure, and function has been to roll to reduce rubbing action.The hair one side of not having hairbrush adopts adhering method to be installed in the lower surface position of mainboard, constitutes the shape integrative-structure, and function has been the effect of brush chalk dust.Roller-less one end of slide bar adopts the screw fixing means to be installed in the upper surface position, two ends of branch plate, constitutes integrative-structure, and function has been the support roller effect.Divide right angle face one end of plate to adopt embedding grammar to be installed in the two ends lateral location of mainboard, function has been total support effect.So just realized the purpose of this utility model.
The advantage of utility model: the utility model has been compared two advantages and improvement with the original blackboard or the cleaning device technology of slabstone;
The first, because the utility model has designed the branch plate in technical scheme, so can large tracts of land erase the board;
The second, because the utility model has designed roller in technical scheme, so it is laborsaving to erase the board; Thereby it is little just more effectively to have solved former blackboard eraser area, problem that can not very fast wiping word.
(4) description of drawings:
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is total side structure schematic diagram of fast clean blackboard eraser of the present utility model;
The numbering of parts explanation in the schematic diagram: 3 fens plate 4 mainboards of 1 slide bar, 2 handrails, 5 handles, 6 rollers, 7 hairbrush
(5) specific embodiment:
In the optimum implementation of fast great blackboard eraser of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:
Its static structure: see also Fig. 1: as shown in the figure, fast clean blackboard eraser of the present utility model.Mainly constitute by slide bar 1, handrail 2, branch plate 3, mainboard 4, handle 5, roller 6, hairbrush 7.Handrail 2 adopts welding method to be installed in the upper end position of slide bar 1, constitutes integrative-structure, and function has been supporting role.Handle 5 adopts the screw fixing means to be installed in the upper face center position of mainboard 4, constitutes fixed structure, and function has been the whole blackboard eraser effect of control.Roller 6 adopts the bearing fixing method to be installed in the front position of slide bar 1, constitutes integrative-structure, and function has been to roll to reduce rubbing action.The no hair of hairbrush 7 simultaneously adopts adhering method to be installed in the lower surface position of mainboard 4, constitutes integrative-structure, and function has been the effect of brush chalk dust.Roller-less one end of slide bar 1 adopts the screw fixing means to be installed in the upper surface position, two ends of branch plate 3, constitutes integrative-structure, and function has been to support roller 6 effects.Divide right angle face one end of plate 3 to adopt embedding grammar to be installed in the two ends lateral location of mainboard 4, function has been total support effect.
Its dynamic structure: in force:
According to mechanics principle, its handle 5 acts on hairbrush 7 by mainboard 4, thereby finishes erasing the board of task.So just realized the purpose of this utility model.Thereby it is little just to have solved former blackboard eraser area, problem that can not very fast wiping word.
Below by using method, the utility model is done more detailed description:
The fast clean blackboard eraser of this utility model is work like this:
In use, when erasing the board, grasp the handrail 4 of handle 5.According to mechanics principle, its handle 5 acts on hairbrush 7 by mainboard 4, thereby finishes erasing the board of task.
Realize that preferred plan of the present utility model is is material with timber, utilize the basic equipment of blackboard eraser factory, take to produce by batch in a large number, the demand with the supply daily life so just can realize practical value of the present utility model and economic worth better.
