Abstract
The utility model discloses an improved steel rule, comprising a rectangle ruler body made of steel. The two long edges of the ruler body present horizontal planes. A concave groove whose length is the same with the ruler body is rolled on a vertical ruler body which is between the two long edges. The section of the concave groove is in an arc shape; the central angle of the concave groove in an arc shape is 10 degrees-35 degrees. The ruler body can be bended can deformed when being pressed by hand due to the concave groove is in an arc shape rolling on the vertical ruler body. The improved steel rule which is easy to carry about and use can extend when the ruler body is pulled by hand, like the steel tape.
Description
Technical field
The utility model belongs to the improvement of steel ruler, particularly improved steel ruler.
Background technology
Though existing steel ruler with or need not, all be straight, carry very inconvenience, to worry also that sometimes it has not been bent or is fractureed.
Summary of the invention
The purpose of this utility model is to provide a kind of improved steel ruler, and the time spent can launch to stretch, and the time spent can not enclose and, and is easy to carry, can be because of being bent or having been fractureed and influence normal use.
The purpose of this utility model is achieved in that a kind of improved steel ruler, the rectangle blade that comprises steel, the edge, two long limits of blade is horizontal plane, longitudinal ruler roll extrusion on one's body between the edge, two long limits has the groove isometric with blade, the cross section of groove is an arc, and the central angle of arc groove is 10 °-35 °.
Because roll extrusion has arc groove on one's body longitudinal ruler, pushes blade with hand, arc groove deforms, and the blade cross section of pushing the position with hand becomes the plane, and that whole blade is taken place is Texturized, as steel tape, is easy to carry; With hand the blade two ends are outwards drawn back, blade can stretch, and is easy to use.The utility model is simple in structure, and is easy to manufacture, is easy to promote.
Description of drawings
Fig. 1 is a vertical view of the present utility model, the side view that Fig. 2 amplifies for the utility model, and Fig. 3 is the front view of the utility model rolled state, Fig. 4 is the side view of the utility model rolled state.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, a kind of improved steel ruler, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the rectangle blade that comprises steel, the edge, two long limits of blade is horizontal plane, mark has size scale respectively on the upper surface of two horizontal plane blades, longitudinal ruler roll extrusion on one's body between the edge, two long limits has the groove isometric with blade, the cross section of groove is an arc, the central angle of arc groove is 10 °-35 °, to guarantee blade bending freely and to stretch.Because roll extrusion has arc groove on one's body longitudinal ruler, pushes blade with hand, arc groove deforms, and the blade cross section of pushing the position with hand becomes the plane, and that whole blade is taken place is Texturized, as steel tape, is easy to carry; With hand the blade two ends are outwards drawn back, blade can stretch, and is easy to use.
Claims (2)
