Description

Dust-free black board eraser

Technical field:

The utility model is divided by International Patent Classification (IPC) (IPC) and is belonged to operation, Department of Transportation, and printing branch is write or drawing appliance; 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; In particular, relate to a kind of improvement of wiping blackboard structure.

Background technology:

At present, the technology about the cleaning device of blackboard or slabstone existing and that once had has been made very fruitful effort to dust-free black board eraser, also once designs many outstanding technical schemes.As being declared by the ringgit fine jade of the Decree of Patent Office of China in 2008, Granted publication number is CN201086560Y, and China Patent No. (ZL) is: No. 200720072009.9 utility model, title are the utility model patents of " blackboard eraser ", the technical scheme that is adopted.Technical elements at the cleaning device of blackboard or slabstone, be of great value innovation and creation, the technological means that it adopts can be adsorbed in blackboard eraser on the blackboard with magnetic, has effectively solved the technical problem that blackboard eraser easily drops, but, also have many deficiencies:

It can't solve dusty problem when erasing the board.

Summary of the invention:

The utility model is exactly at the problems referred to above, and a kind of simple in structure, easy to use, dust-free black board eraser of not having dust when erasing the board is provided.

For reaching above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises gripper shoe, the both sides of its structural feature gripper shoe link to each other with housing, be with wiper on the gripper shoe, be provided with active roller between wiper and the gripper shoe in the housing, the handle of active roller is arranged on outside the housing; Be provided with water injection hole and positioning spiro pit corresponding to wiper on the housing; Bolt is arranged in the positioning spiro pit.

As a kind of preferred version, housing is outer to be provided with handle by connecting rod.

As another kind of preferred version, the two ends of gripper shoe are provided with pole, and pole is provided with auxiliary wheel.

The beneficial effects of the utility model:

1, simple in structure:

The both sides of gripper shoe of the present utility model link to each other with housing, are with wiper on the gripper shoe, are provided with active roller between wiper and the gripper shoe in the housing, and the handle of active roller is arranged on outside the housing; Be provided with water injection hole and positioning spiro pit corresponding to wiper on the housing; Bolt is arranged in the positioning spiro pit; Its member is few, and the utility model is simple in structure thus.

2, easy to use:

Because design feature of the present utility model is injected water by water injection hole, by handle rotation active roller, wiper rotates with active roller then, when going to wetting wiper outside the housing, can erase the board; Method of operating is simple, and is easy to use; In addition, housing of the present utility model is outer is provided with handle by connecting rod; By easier hand control the utility model.

There is not dust when 3, erasing the board:

Because the utility model is when erasing the board, use be wetting wiper, so blackboard wiping does not have dust fully; After wiper is dirty, can pass through active roller, wiper is rotated to clean position, can continue to erase the board; There is not dust when the utility model erases the board thus.

4, wiper rotates easily:

Because the two ends of gripper shoe of the present utility model are provided with pole, pole is provided with auxiliary wheel; So when rotating active roller, auxiliary wheel rotates, and wiper is rotated easily thereupon.
