Abstract
A safe compass ruler comprises a ruler body, round holes and a positioning device. The round holes are formed in the ruler body and correspond to scales on the ruler body, the positioning device is arranged over the round hole corresponding to the 'zero' scale and fixedly connected with the ruler body, the positioning device is composed of a cylindrical outer shell, a spring and a solid cylinder, an opening in one end of the cylindrical outer shell is a cylindrical outer shell round hole, the diameter of the opening in the end of the cylindrical outer shell is smaller than that of an inner circle of the cylindrical outer shell, and the other end of the cylindrical outer shell is a normal end with a round hole. The spring is clamped in the cylindrical outer shell, one end of the spring is clamped into the round hole corresponding to the 'zero' scale, and the spring is slightly lower than the cylindrical outer shell. The surface of the solid cylinder is smooth, one end of the solid cylinder is an upward plane, the other end of the solid cylinder is in a downward pyramid type, and the solid cylinder is inserted into the cylindrical outer shell. The safe compass ruler is simple in structure, convenient to carry, safe and easy to operate, and improves plotting efficiency.
Description
Technical field
The utility model belongs to the study article field, relates to a kind of a kind of safety compasses ruler that can doublely do compasses and ruler.
Background technology
When daily study is drawn, draw straight line at present, need to use ruler during measurement, draw bowlder and need to use compasses, if a kind of instrument that can not only regard compasses but also can regard ruler is arranged, will make picture more convenient, carry more convenient.
Summary of the invention
The utility model is in the middle of the picture process, compasses only are used for picture circle, ruler only is used for measuring and drawing the limitation of straight line and the situation that the compasses prong is hurted sb.'s feelings easily, the drawing tools of a kind of safety that not only can regard the compasses use but also can be used for measuring that provides.
The technical scheme that the utility model technical solution problem is taked is: this device comprises the ruler body, circular hole, positioner, on the described ruler body with circular hole; Described circular hole is corresponding with scale on the ruler body; Described positioner is fixedly connected with the ruler body directly over the corresponding circular hole of " 0 " scale; Described positioner is by cylindrical shell, spring, and solid cylinder forms; Described cylindrical shell one end opening is the cylindrical shell circular hole, and its diameter is less than circular diameter in the cylindrical shell, and an end is normal circular hole end, and slightly larger in diameter is circular hole on the ruler body, and normal circular hole end is fixed in the corresponding circular hole of ruler body " 0 " scale place; Described spring one end snaps in the cylindrical shell, and an end snaps into the corresponding circular hole of " 0 " scale place, and height is a little less than cylindrical shell; Described solid cylinder smooth surface, an end be the plane up, an end be pyramid type down; It is inner that described solid cylinder inserts cylindrical shell, highly is higher than cylindrical shell, and with the cylindrical shell equal-height position circular protrusion arranged, and is stuck between the cylindrical shell circular hole place and spring in the cylindrical shell.
The utility model has following beneficial effect with respect to prior art: simple in structure, safety is easy to operate, and a chi is dual-purpose, and mapping efficient is high.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the profile of A place among Fig. 1 (positioner and ruler body).
1. ruler body, 2. circular hole, 3. positioner, 31. cylindrical shells, 311. cylindrical shell circular holes, 32. springs, 33. solid cylinders, 331. circular protrusions, 332. conical end.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing: please referring to accompanying drawing 1, Fig. 2, this device comprise ruler body 1, circular hole 2, positioner 3, on the described ruler body 1 with circular hole 2; Described circular hole 2 is corresponding with scale on the ruler body 1; Described positioner 3 is fixedly connected with ruler body 1 directly over the corresponding circular hole 2 of " 0 " scale; Described positioner 3 is by cylindrical shell 31, spring 32, and solid cylinder 33 forms; Described cylindrical shell 31 1 end openings are cylindrical shell circular hole 311, and its diameter is less than cylindrical shell 31 interior circular diameters, and an end is normal circular hole end, and slightly larger in diameter is circular hole 2 on ruler body 1, and normal circular hole end is fixed in the corresponding circular hole of ruler body 1 " 0 " scale 2 places; Described spring 32 1 ends snap in the cylindrical shell 31, and an end snaps into the corresponding circular hole of " 0 " scale 2 places, and height is a little less than cylindrical shell 31; Described solid cylinder 33 smooth surfaces, an end be the plane up, an end is pyramid type down 332; Described solid cylinder 33 inserts cylindrical shell 31 inside, highly is higher than cylindrical shell 31, and with cylindrical shell 31 equal-height positions circular protrusion 331 is arranged, and is stuck between cylindrical shell circular hole 311 places and spring 32 in the cylindrical shell 31.
When a kind of safety compasses ruler of the present utility model uses, ruler body 1 is set level on paper, under normal circumstances, spring 32 is in diastole state, and the conical end 332 of solid cylinder 33 does not contact paper, and ruler body 1 itself can be used for measuring and drawing straight line at this moment.
When using as compasses, take draw a radius as 20 millimeters circle as example, hand is clutched solid cylinder 33 and is pressed down, spring 32 is compressed, until conical end 332 is pricked paper, reaches the fixed position effect, put as the center of circle take this, enter on 20 millimeters scales corresponding circular hole 2 with penholder, take this distance of putting the corresponding circular hole 2 of " 0 " scale as radius, can draw radius with a drive ruler body 1 rotation is 20 millimeters circle.Should be appreciated that preferred embodiment discussed above, only be used for description and interpretation the utility model, be not limited to the utility model.
A kind of safety compasses ruler of the utility model, simple in structure, easy to carry, safety is easy to operate, and a chi is dual-purpose, has improved mapping efficient.
