Abstract
The utility model relates to a folding ruler which includes two rulers with equal length; the two rulers are connected at the location of the shafts at the end sides; wherein, the front surface of one ruler is processed with a semi-spherical salient; the surface of the other ruler is processed with a concave surface and the positions of the salient and the concave surface are corresponding; the back surfaces of the rulers are respectively fixed with a rubber cushion. When being deposited, the two rulers are folded together and the semi-spherical salient is inserted into the concave surface to lead the two rulers to be blocked together for increasing the firmness; when in use, the ruler after fold can be normally used; when the length is not enough, the folded ruler can be turned over and opened to increase the length. The utility model has a simple structure, is convenient and practical, has a beautiful appearance and a reasonable technique, etc.
Description
Technical field
The utility model relates to a kind of drawing, survey tool, especially a kind of new-type ruler of collapsible placement.
Background technology
At present, ruler is still topmost linear measure longimetry in people's study, the work, drawing tool.But present ruler structure is too single, measures, draws length and be subjected to the ruler length restriction, in case when ruler length is not enough, just occur error easily; Though some folding rulers are also arranged on the market, lack stability, very inconvenience during use.For this reason, we provide a kind of new-type folding ruler very necessary.
Summary of the invention
The purpose of this utility model provides a kind of folding ruler, is used to solve common ruler and can't folds, wait built on the sand problem.
For achieving the above object, the utility model folding ruler comprises that two rules mould the material ruler, and two rulers are isometric, and axle links together at place, end limit; A ruler front processes hemispherical projections therein, and at another ruler Surface Machining concave surface, and projection is corresponding with the position of concave surface; Paste fixedly rubber blanket respectively at two ruler back sides.
After adopting said structure, when depositing, two rulers are folded, hemispherical projections is inserted in the concave surface, make two rulers be stuck, increase fastness; In use, can normally use the ruler after folding, when length is not enough, turning folding ruler, the increase length opened; In addition, the rubber blanket at the ruler back side can increase frictional force, can avoid ruler to slide in use, improves drawing, certainty of measurement.
The utility model has the advantages that: simple in structure, convenient and practical, good looking appearance, technology are reasonable, easy to carry and store, and stability is strong during use.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model folding ruler.
The specific embodiment
As shown in Figure 1, the utility model folding ruler comprises that two rules mould the material ruler, and two rulers are isometric, and axle links together at place, end limit; In the positive processing of ruler 1-1 hemispherical projections 2, at ruler 1-2 Surface Machining concave surface 3, and projection 2 is corresponding with the position of concave surface 3; Paste fixedly rubber blanket 4 respectively at two ruler back sides.
Claims (1)
1, a kind of folding ruler, comprise that two rules mould the material ruler, is characterized in that: two rulers are isometric, and axle links together at place, end limit; In the positive processing of ruler (1-1) hemispherical projections (2), at ruler (1-2) Surface Machining concave surface (3), and projection (2) is corresponding with the position of concave surface (3); Paste fixedly rubber blanket (4) respectively at two ruler back sides.
