Abstract
The utility model relates to a foldable triangular ruler. A triangular ruler with a larger size is divided into two or more than two ruler bodies; a hinge is arranged between two or more than two foldable ruler bodies; a central shaft of the hinge is a movable shaft; and the central shaft on the hinge is taken out to decompose the ruler into a plurality of rulers with small specifications. The ruler bodies are foldable so that the foldable triangular ruler is more convenient and flexible to carry and use, and the phenomena that the ruler is broken off and the like are reduced.
Description
Technical field
The folding set square of the utility model belongs to the metering device field, and chi is used in particularly a kind of metering.
Background technology
In the existing chi class, especially for the set square of picture purpose, the size of blade has different specifications as required, and is when using the triangle of large-size, often not too convenient when carrying.When the student far away that particularly leaves school carries ruler at a distance, do not notice slightly that the ruler of putting into school bag just might fracture, moreover a kind of ruler scope of application of specification is often narrow.
Summary of the invention
The purpose of the utility model is the problem of carrying to the set square inconvenience of existing large-size, proposes a kind of technical scheme of the folding set square that is convenient for carrying.
The technical scheme of the folding set square of the utility model is such.The set square of a large-size is divided into two or more than two blade, between folding two or more than two blade, hinge is housed.Central shaft on the hinge is a movable axis, takes out the central shaft on the hinge, can ruler be resolved into the ruler of several small dimensions.
The folding set square of the utility model has following advantage:
1. because blade is collapsible, carry, easy to use.Particularly to active students in middle and primary schools, folding set square can directly be put into writing case, thereby can reduce that ruler fractures etc. and damage the generation of phenomenon.
2. because the central shaft on the folding set square burst hinge can be taken out, large scale triangle ruler can resolve into several small size triangle rulers, also can at any time several little triangle rulers be assembled into big triangle ruler, uses more extensive and flexible.
Description of drawings
Accompanying drawing is the structural representation of the folding set square of the utility model.
The specific embodiment
As shown in the figure, drawing square is divided into four blades.Hinge (2) is housed between folding four blades (1), like this, just can the triangle blade of three small dimensions be folded into above the rectangle blade.Ruler is in the state of being convenient for carrying; During use, three triangle blades are opened get final product, the movable axis of the center uranium (4) on the hinge (2) for twitching taken out central shaft (4), once having become four to a big set square little ruler.(3) be the blade clearance gap.
Claims (2)
1. folding set square comprises blade (1) and hinge (2), it is characterized in that between folding two or more than two blade (1), hinge (2) being housed.
2. a kind of folding set square according to claim 1 is characterized in that the movable axis of center (4) for twitching on the hinge (2).
