Abstract

The utility model discloses a magnetic ruler, which comprises a ruler body and is characterized in that: a permanent magnetic strip and/or permanent magnetic block are arranged on the ruler body. As the permanent magnetic strip and/or permanent magnetic block are arranged on the ruler body, the magnetic ruler can be absorbed on the blackboard made from iron magnetic material or drawing board, which is not easy to slide and will not fall to the ground; when the operator leaves the blackboard or drawing board, the ruler is not required to move. The utility model is of an easy application and an accurate chart drawing, which can save the time and can effectively improve the teaching effect and the working efficiency.

Description

The magnetic ruler
Technical field
The utility model relates to the drawing assistant product, specifically, relates to a kind of magnetic ruler.
Background technology
Teacher and engineers and technicians are when drawing a diagram, tend to because ruler slides on blackboard or drawing board even drops to the ground, perhaps because when leaving blackboard or drawing board, ruler must be removed, and it is inaccurate to cause chart to be drawn, not only bother but also lose time, influence teaching efficiency and operating efficiency.
Summary of the invention
The purpose of this utility model provides a kind of magnetic ruler that can be adsorbed on ferromagnetics (metal and alloys thereof such as iron, cobalt, nickel) blackboard or the drawing board.The technical scheme that adopts is as follows:
A kind of magnetic ruler comprises the chi body, it is characterized in that: described chi body is provided with permanent magnetic strip and/or permanent magnets.
Described chi body can be ruler, set square, T-square etc.
Contact-making surface one side of preferred described chi body and blackboard or drawing board is provided with groove, and permanent magnetic strip and/or permanent magnets are embedded in the corresponding grooves.Also permanent magnetic strip and/or permanent magnets can be wrapped in the chi body.
The quantity of described permanent magnetic strip and/or permanent magnets and position should rationally be provided with according to concrete chi body, make the magnetic force of generation that the magnetic ruler is adsorbed on blackboard or the drawing board and be difficult for sliding, do not hinder operating personnel that the magnetic ruler is taken off from blackboard or drawing board again.For example,, a permanent magnetic strip can be set along its length on the chi body, also can on the chi body, be arranged to few two permanent magnets along its length for ruler; For set square, can on the both sides at least of chi body, each a permanent magnetic strip be set along its length, also can be on the chi body at least two (preferred three) permanent magnets of diverse location setting, also can permanent magnetic strip and permanent magnets combine (such as a permanent magnetic strip is set along its length, and one permanent magnets being set on one side of chi body) at the position, diagonal angle on this limit; For T-square, can be on the both sides of chi body each a permanent magnetic strip is set along its length, also can be on the chi body at least two permanent magnets of diverse location setting, also can on one side of chi body, a permanent magnetic strip be set and at least one permanent magnets is set on another side.Below just for some preferred examples, the adoptable concrete scheme of the utility model more than these.
The utility model is owing to be provided with permanent magnetic strip and/or permanent magnets on the chi body, therefore the magnetic ruler can be adsorbed on the blackboard of being made by ferromagnetics or drawing board, be difficult for sliding, can not fall on the ground yet, needn't remove ruler when operating personnel leave blackboard or drawing board, easy to use, graph making is accurate, save time, effectively improve teaching efficiency and operating efficiency.
