Description
Technical field
The utility model designs a kind of ruler, relates in particular to a kind of ruler of adjustable in length.
Background technology
In learning process, as drawing, when going out radio message receiption by hand or blackboard newspaper, need using the ruler of different length.Existing ruler roughly is divided into two kinds, and a kind of is that length is that chi is used in the study of 20cm, but this ruler is shorter, is not suitable for using at big plane space; Another kind is the long teaching gauge of length, but this ruler carries inconvenience owing to longer, in addition, can not adjust length during use.
Summary of the invention
The technical problem that the utility model will solve provides a kind of ruler of adjustable in length, and it also is easy to carry.
In order to solve the problems of the technologies described above, the technical scheme of the utility model is:
A kind of ruler of adjustable in length comprises the straight section of some serial connections, and adjacent straight section connects through the cross connector, and the medial recess of adjacent straight section opposite end is to admit relative two articulated jibs of cross connector respectively, and straight section and articulated jib are rotationally connected.
Said straight section comprises first section, two interludes and tail end, the first section concave end with tail end.
Said every section straight section is long to be 8cm.
The utility model is through some straight sections serial connection, and adjacent two straight sections connect through the cross connector, makes the utility model integral body to fold or to stretch, and obtains obstructed length, and is easy to carry and use.
Description of drawings
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 first section, 2 cross connectors, 3 interludes, 4 ears, 5 rears, 6 articulated columns.
The specific embodiment
Fig. 1 shows the structural representation of the utility model, and as can be seen from the figure, a kind of ruler of adjustable in length comprises first section 1, two interlude 3 and tail end 5.Connect through cross connector 2 between first section 1 and adjacent interlude, two interludes and interlude and the adjacent rear end 5.First section 1 relative section medial recess with relative section of relative section, two interlude of adjacent interlude and interlude and adjacent rear end 5 is to admit relative two articulated jibs of cross connector 2 respectively.Form ear 4 respectively with relative section of relative section, two interlude of adjacent interlude and relative section medial recess both sides of interlude and adjacent rear end 5 for first section 1; Ear 4 is provided with axis hole, to rotate the articulated column 6 on the articulated jib of admitting cross connector 2.First section 1, two interlude 3 of the utility model and tail end 5 every section length are 8cm.
First section 1 is the normal mounting state with adjacent interlude 3 among Fig. 1, and two interludes and interlude and adjacent rear end 5 are disassembled form.
