Description

A kind of novel magnetic blackboard
The utility model relates to a kind of novel magnetic blackboard.(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 is write or drawing article, and the assistant product group of writing or draw can repeat blackboard technical group field in the plate of writing or drawing of usefulness or the tablet.Be numbered B43L 1/04.
At present, the right demand of the black power of technology about blackboard in the plate of writing or drawing that can repeat usefulness or the tablet existing and that once had was all done very fruitful effort, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1994 by sieve Wang Shi, Granted publication number is CN2152618Y, the transfer patent No. (ZL) is: No. 93233421.0 utility model title is the utility model patent of swinging blackboard, the technical scheme that is adopted, be a routine of great value invention aspect the blackboard in plate of writing or drawing that can repeat usefulness or tablet, it has solved blackboard effectively can rotating problem.But still have some deficits, it also is difficult to solve simple in structure, and system is convenient, the problem that usability is strong.
The purpose of this utility model is to provide a kind of novel magnetic blackboard.Simple in structure to solve, system is convenient, the problem that usability is strong.
The purpose of this utility model is achieved in that a kind of novel magnetic blackboard of this utility model.Mainly constitute by chute, slide track bar, plate body, lettering pen, bracing frame, back shaft, little flap.Its major part slide track bar, lettering pen are made with magnetic material machining.Plate body is made of a plurality of little flaps, and little flap N is extremely outer under the normality returns, and returns in little flap plate, and little flap is supported by the back shaft on the bracing frame, the lettering pen lower end N utmost point, the upper end S utmost point, the upward bottom of blackboard body is a chute, slide track bar is housed in chute, and the slide track bar inner face S utmost point returns the N utmost point outward.So just realized the purpose of this utility model.
The technology of blackboard has been compared an advantage and improvement in the plate of writing or drawing of the utility model and original repeated usefulness or the tablet;
The first, because the utility model has designed the magnet flap in technical scheme, there are not dust, health in the use.Thereby just can more effectively solve simple in structurely, system is convenient, the problem that usability is strong.
Accompanying drawing provides structural representation of the present utility model:
