Abstract
The utility model relates to a compasses ruler, which comprises a ruler with scales, wherein a slide way and a strip-shaped slot are arranged in the length direction of the ruler; a slide block is arranged on the slide way; a through hole is formed in the slide block; and an elastic supporting part is arranged in the through hole. A positioning needle for fixing the center of a circle is inserted on the elastic supporting part in a penetrating manner; when the compasses ruler is used, the positioning needle is pressed, so that the needle tip of the positioning needle extends out of the undermost surface of the ruler for fixing the center of the circle. The positioning needle and the slide block freely move in the strip-shaped slot, and are matched with the scales to determine the radius of the circle; a pencil lead for drawing is arranged at one end of the strip-shaped slot, and used for driving the compasses ruler to rotate, so that a needed circle is drawn out. By virtue of the compasses ruler, the function of the ruler and the function of the compasses are combined; the pencil lead for drawing is convenient to place; and meanwhile, the needle tip of the positioning needle is prevented from forming unnecessary printing dots on the paper surface.
Description
Technical field
The utility model relates to the stationery field, particularly a kind of compasses chi.
Background technology
Common compasses are independent drawing tools, and common ruler only is suitable for the picture straight line, if ruler and compasses are combined formation compasses chi, just can realize the combination of both functions, reach purpose easy to use, that save material.Chinese patent CN209295248Y goes up a kind of compasses chi of record, at the slide block of common ruler central authorities' installation slideway and band pencil-lead, metal or nonmetallic pin mark are installed by side's fixed point place, are the center of circle with the pin mark place when using, record radius according to the scale sliding slider, can the picture circle.Yet there is following problem in this compasses chi: when using as ruler, pin mark and pencil-lead can touch paper, stay the seal point, and comparatively bother in adjustment and replacing pencil-lead.
The utility model content
The utility model aims to provide a kind of unnecessary seal point, the replacing of pen core and compasses chi easy to adjust of can not producing.
In order to achieve the above object, the utility model is in the following way:
A kind of compasses chi, comprise the ruler with scale, along being respectively equipped with slideway and bar-shaped trough on the length direction of ruler, slide block is installed on the slideway, the compasses chi also comprises for the fixing pilot pin in the center of circle, has for described pilot pin at slide block and is inserted in through hole in it, and the one side that slide block is set with ruler is upper bottom surface, corresponding another side is bottom surface, is provided with in described through hole in order to the needle point holder of the described pilot pin elastic support member from the ruler bottom surface.
Above-mentioned elastic support member comprises circular supporting seat and elastomeric element, described pilot pin is arranged in the described circular supporting seat and upper and lower end passes respectively outside the described circular supporting seat, and described elastomeric element is located between the upper end of described circular supporting seat and described pilot pin.
Above-mentioned elastomeric element is spring or rubber washer.
Above-mentioned pilot pin upper end can be provided with button, and elastomeric element one end is fixed on the button bottom, and the other end is fixed on the top of described circular supporting seat.
Above-mentioned pilot pin is outer can be with stop collar, and described stop collar is positioned at described circular supporting seat below.
Adopt said structure, pilot pin is installed on the slide block by elastic support member, and when using as ruler, elastic support member can not produce unnecessary seal point with the needle point holder of the pilot pin bottom surface from ruler.When using as compasses, according to required radius, slide block is moved to corresponding position along slideway, press the bottom surface that needle point that pilot pin makes pilot pin exposes ruler, be used for the fixedly center of circle, the nib of pen, gel ink pen, pencil etc. is placed an end of bar-shaped trough, drive just rotatable picture circle of ruler by nib.After painting, pen packed up get final product, do not have the problem of changing pen core, very convenient.
Description of drawings
Accompanying drawing 1 is these compasses chi overall structure schematic diagram.
Accompanying drawing 2 and accompanying drawing 3 are these compasses chi slide block and pilot pin structural representation.
Accompanying drawing 4 is that these compasses chi uses view.

The specific embodiment
Specify the specific embodiment of the present utility model below in conjunction with accompanying drawing:
Shown in accompanying drawing 1 to 3, these compasses chi comprises the ruler 1 that has scale 2, has bar-shaped trough 5 and slideway 3 on ruler 1 along its length, and respective slide 4 is installed on the slideway 3, and slide block 4 can be free movable on slideway 3.Have through hole 7 on the slide block 4, pilot pin 6 can be inserted in the through hole 7.The one side that slide block 4 is set with ruler 2 is upper bottom surface, corresponding another side is bottom surface. in through hole 7, be provided with elastic support member 9, elastic support member 9 is supporting pilot pin 6, when not doing the compasses use, elastic support member 9 from ruler 2 bottom surfaces, makes pilot pin needle point 62 not stretch out ruler 2 bottom surfaces 62 holders of pilot pin needle point.
Above-mentioned elastic support member 9 can adopt such structure: elastic support member 9 comprises circular supporting seat 91 and elastomeric element 92.Elastomeric element 92 can be selected spring or rubber washer for use.Circular supporting seat 91 is fixed among the through hole 7 of slide block 4, and pilot pin 6 is arranged in the circular supporting seat 91, and the upper and lower end of pilot pin 6 passes respectively outside the circular supporting seat 91.Elastomeric element 92 is set in outside the pilot pin 6 and between circular supporting seat 91 and pilot pin 6 upper ends, and the external diameter of elastomeric element 92 is greater than the internal diameter of circular supporting seat 91.
Further, the button of Gong pressing 61 can be installed in the upper end of pilot pin 6, elastomeric element 92 1 ends are fixed on the bottom of button 61, the other end is fixed on the top of circular supporting seat 91.By this structure pilot pin 6 is limited within certain scope of activities, pilot pin 6 can not come off easily.Also can stop collar 8 be arranged at pilot pin 6 overcoats, the external diameter of stop collar 8 is greater than the internal diameter of circular supporting seat 91, and stop collar 8 is positioned at circular supporting seat 91 belows, will be subjected to certain restriction, difficult drop-off when pilot pin 6 moves upward like this.
Accompanying drawing 4 is that these compasses chi uses state diagram, and as shown in the figure, pilot pin 6 moves along bar-shaped trough 5 during use, cooperate ruler scale 2, to determine the radius of required compasses, press pilot pin 6 and make pilot pin needle point 62 (Fig. 4 does not draw) move downward contact paper, the fixedly center of circle.Nib is put into bar-shaped trough 5 one ends, pin pilot pin 6 during use on the other hand, drive the compasses chi by nib on the other hand and rotate, make needed circle.Adopt this compasses chi can not stay unnecessary seal point on paper, do not have the problem of changing pen core simultaneously, use very convenient.
The above embodiments and diagram and non-limiting product form of the present utility model, any affiliated technical field personnel carry out suitable variation or modification to it, all should be considered as not breaking away from category of the present utility model.
