Abstract
A folding ruler comprises a plurality of straight ruler sections. Adjacent straight ruler sections are connected through pin rolls in an end-to-end mode. Matched grooves are formed in the end portions of the connection position of every two straight ruler sections to enable the thickness of the connection positions to be identical with that of the straight ruler sections. Scales are arranged on the long side of each straight ruler section, and the other long side is in the shape of a wave line. Round and polygonal through holes are further formed in the straight ruler sections to facilitate drawing. The pin rolls are adopted to connect the adjacent straight ruler sections, and the two straight ruler sections can be folded and shortened and are convenient to carry. The folding ruler solves the problem that the ruler cannot be placed with other stationary due to the fact that the straight ruler sections are too long. In addition, teachers can help students to know and understand polygons deeply by bending the straight ruler sections into different shapes and are not required to carry more teaching appliances.
Description
Technical field
The utility model relates to a kind of stationery or teaching aid, a kind of can folding particularly, the folding chi that is convenient for carrying.
Background technology
Existing ruler is generally much longer than other stationery length, is inconvenient to carry.
Summary of the invention
The purpose of this utility model provides a kind of folding chi, can folds shorten, be convenient for carrying; Also can be bent into different figures by folding chi in addition, the convenient picture or teaching.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of folding chi, comprise the polylith ruler, and join end to end by bearing pin between adjacent two rulers, the end, junction of two rulers is provided with the groove that cooperatively interacts, and makes junction thickness identical with the thickness of ruler.
One long limit of described ruler is provided with scale, and another long limit is the wave wire; Also be provided with circle and polygon through hole on the described ruler, the convenient picture.
The utility model adopts bearing pin that adjacent ruler is connected, and two rulers can folds shorten, is convenient for carrying, and having solved can not be with its difficult problem of placing with other stationery because ruler is long; In addition, the teacher can also strengthen the student to polygonal understanding and understanding by ruler being bent into different shapes, and difference is carried more teaching aid.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the side view of the utility model two ruler junctions.
Fig. 2 is use state diagram of the present utility model.
The specific embodiment
As Fig. 1-shown in Figure 2, the utility model comprises polylith ruler 1, joins end to end by bearing pin 2 between adjacent two rulers, is characterised in that: the end, junction of two rulers 1 is provided with the groove 3 that cooperatively interacts, and makes junction thickness identical with the thickness of ruler.
One long limit of described ruler 1 is provided with scale, and another long limit is the wave wire.
Also be provided with circle and polygon through hole on the described ruler 1.
As required ruler is folded or launches to be combined into different shapes, the convenient use.
Claims (3)
