Abstract

The utility model provides a combined bevel protractor, comprising a protractor. The utility model is characterized in that the outer ring of the protractor is provided with scales of 0-180 DEG from left to right, and the inner ring of the protractor is provided with scales of 180-0 DEG from right to left; two hinges are disposed at the middle of a ruler, thereby the ruler can be half-and-half folded; the upper end of the ruler is provided with a hollow peach shape, with the peach tip being in the middle of the ruler, and the lower half part of the ruler is provided with a hollow in the width of 2-3 millimeter; the protractor is connected to the ruler through a movable shaft. The combined bevel protractor can be used as a protractor and also a ruler. When being used as a protractor, the bevel protractor can measure an angle larger than 180 DEG. When the combined bevel protractor is not in use, it is only required to fold the ruler and rotate the ruler in a manner that the bottom of the ruler and that of the protractor overlap, making the protractor and the ruler be integrated into one piece.

Description

A kind of combination bevel protractor

One, technical field:

The utility model relates to measurer, specifically, relates to a kind of combination bevel protractor.

Two, background technology:

Current student's study article is a lot, stationery aspect especially, and pen, pencil, angle square, pipe, set square etc., often a writing case all fails to lay down.

Three, summary of the invention:

The utility model is at the problems referred to above, and a kind of combination bevel protractor is provided, and effectively places thereby reach stationery.

For realizing described purpose, the utility model is taked angle square and ruler are combined.

The utility model provides a kind of combination bevel protractor, and comprise that angle square, ruler is characterized in that: the outer ring has 0 ° to 180 ° scale from left to right on the angle square, and inner ring has 180 ° to 0 ° scale from right to left on the angle square; There is two hinge centre in the length of ruler, and it makes that this ruler can folded in half, and there is the peach shape of individual hollow out the ruler upper end, and the peach point of peach shape is in the centre of ruler, and ruler the latter half has the hollow out of one 2～3 mm wide; Angle square is to be connected by mobilizable movable axis with ruler.

The beneficial effects of the utility model are can make angle square to use, and also can make ruler and use, and do can measure greater than 180 ° angle angle when angle square uses.As long as folding ruler overlaps the bottom of ruler and angle square the ruler rotation, two kinds of measurers are integrated when not using.

Four, description of drawings:

Fig. 1 is the schematic diagram that the utility model launches

Fig. 2 is the folding schematic diagram of the utility model

1. movable axis among Fig. 1,2. hinge, 3. peach point, 4. hollow out 5. is rulers, 6 angle squares.

Five, the specific embodiment:

Describe the utility model in detail below in conjunction with accompanying drawing 1-2.

Shown in Fig. 1-2, a kind of combination bevel protractor, combine through movable axis 1 by angle square 6, ruler 5, there is two hinge 2 centre in the length of ruler 5, it makes that this ruler can folded in half, there is the peach shape of individual hollow out the ruler upper end, and the peach point 3 of peach shape is in the centre of ruler, and ruler the latter half has the hollow out 4 of one 2～3 mm wide; Angle square 6 is to be connected by mobilizable movable axis 1 with ruler 5.

Claims

1. one kind is made up bevel protractor, and comprise that angle square, ruler is characterized in that: the outer ring has 0 ° to 180 ° scale from left to right on the angle square, and inner ring has 180 ° to 0 ° scale from right to left on the angle square; There is two hinge centre in the length of ruler, and it makes that this ruler can folded in half, and there is the peach shape of individual hollow out the ruler upper end, and the peach point of peach shape is in the centre of ruler, and ruler the latter half has the hollow out of one 2～3 mm wide; Angle square is to be connected by mobilizable movable axis with ruler.
