Abstract

The invention relates to multifunctional radius-adjustable compasses with scales. The multifunctional radius-adjustable compasses with the scales are characterized by comprising a first scale positioning bolt, a second scale positioning bolt, a pen, a pen holder, a radius rod, a fixing tube and a circle center fixing needle, wherein the pen is connected with the radius rod through the pen holder and the first scale positioning bolt; the circle center fixing needle is connected with the radius rod through a fixing tube; and the fixing tube is also provided with the second scale positioning bolt. The circle center fixing needle can move along the radius rod with length scale values, so that the radius can be accurately adjusted; circles and arcs can be conveniently scratched on surfaces of parts made of different materials; and the parts can be trimmed along the circles or the arcs.

Description

A kind of multi-functional diameter-adjustable band Graduated compasses
Technical field
The invention discloses a kind of multi-functional diameter-adjustable band Graduated compasses, belong to cultural goods design field.
Background technology
When existing compasses are used in the market, the adjusting of radius is inconvenient, and can not regulate comparatively accurately, in Practical Project, sometimes need to be at upper drawing circle camber lines such as harder metal, metal sheet or glass, even need to carry out cutting by certain radius, in the market the single needs that cannot meet Practical Project of existing calipers function.
Summary of the invention
Some shortcomings for the said goods, the present invention is by carrying out along the radius rod of a strip length scale value mobile center of circle locking pin, realizing pair radius regulates comparatively accurately, change the pen of different pen cores simultaneously, can conveniently realize at the piece surface with unlike material and draw circle and circular arc, also can realize the function that cuts along circle or circular arc.
The technical solution adopted in the present invention is:
A multi-functional diameter-adjustable band Graduated compasses, comprises the first scale bolt, the second scale bolt, pen, penholder, radius rod, stationary pipes, center of circle locking pin; Described pen is connected by penholder and the first scale bolt and radius rod; Described center of circle locking pin is connected by stationary pipes and radius rod, and the second scale bolt is also set in described stationary pipes.
Above-mentioned radius rod upside is a plane, in plane with length scale value.
Above-mentioned Graduated compasses also comprises handle tube and handle cap; Described center of circle locking pin is comprised of upper locking pin and lower locking pin; Fixed pin and lower locking pin are fixedly mounted on respectively in two holes up and down of stationary pipes, the peripheral suit of fixed pin handle tube, described handle cap is arranged on the top of locking pin and handle tube, fixed pin matches with handle tube and handle cap, can in handle tube and handle cap, freely rotate.。
Above-mentioned stationary pipes can be along moving freely on the length direction of radius rod, a definite position that also can stationary pipes be fixedly connected on radius rod by a scale bolt wherein.
The beneficial effect of the relative prior art of the present invention:
The present invention is by carrying out along the radius rod of a strip length scale value mobile center of circle locking pin, realizing pair radius regulates comparatively accurately, change the pen of different pen cores simultaneously, can conveniently realize at the piece surface with unlike material and draw circle and circular arc, also can realize the function that cuts along circle or circular arc direction, radius regulates easily and is more accurate, and the scope of application is wider.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the multi-functional diameter-adjustable band of the present invention Graduated compasses.
Fig. 2 is the blast schematic perspective view of the multi-functional diameter-adjustable band of the present invention Graduated compasses.
Fig. 3 is that the present invention uses state diagram.
The specific embodiment
For further setting forth the present invention, reach technological means and the effect that predetermined object is taked, below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment, structure, feature and effect thereof to proposing according to the present invention, be described in detail as follows.
As shown in Figure 1, a kind of multi-functional diameter-adjustable band Graduated compasses, comprises the first scale bolt 1, the second scale bolt 11, pen 2, penholder 3, radius rod 4, stationary pipes 7, center of circle locking pin 8; Pen 2 is connected with radius rod 4 by penholder 3 and the first scale bolt 1; Center of circle locking pin 8 is connected by stationary pipes 7 and radius rod 4, and the second scale bolt 11 is also set in stationary pipes 7.
As shown in Figure 2, radius rod 4 upsides are planes, in plane with length scale value.
As shown in Figure 2, compasses also comprise handle tube 5 and handle cap 6, and center of circle locking pin 8 is comprised of upper locking pin 9 and lower locking pin 10; Upper locking pin 9 and lower locking pin 10 are fixedly mounted on respectively in two holes up and down of stationary pipes 7, the peripheral suit handle tube 5 of upper locking pin 9, handle cap 6 is arranged on the top of locking pin 9 and handle tube 5, upper locking pin 9 matches with handle tube 5 and handle cap 6, can in handle tube 5 and handle cap 6, freely rotate.
Stationary pipes 7 can be along moving freely on the length direction of radius rod 4, a definite position that also can stationary pipes 7 be fixedly connected on radius rod 4 by a scale bolt 1 wherein.
Pen 2 is a kind of removable seriation pens with multiple use function, nib can be the harder alloy tool steel of the softer lead in a pencil of material, material etc., change different pens and can, at upper drawing circle or circular arcs such as paper products, metal, glass, also can realize thin-wall part along the cutting in circle or circular arc direction.
The operation principle of multi-functional diameter-adjustable band Graduated compasses:
According to above composition, the operation principle of multi-functional diameter-adjustable band Graduated compasses is as follows: when each part is positioned at position as shown in Figure 3, the air line distance between nib center and locking pin center, the center of circle is the round least radius of painting, as shown in Figure 1, during use, take this radius as basis, according to paint circle or large young pathbreaker's stationary pipes 7 of arc radius, along the length direction of radius rod 4, move to needed radius value, mobile distance is determined by the scale value on radius rod 4, this value adds that least radius value is exactly needed drawing radius, determine after drawing radius, the second scale bolt 11 on rotation right side fixes stationary pipes 7, with finger, pin handle cap 6 downwards and fix center of circle locking pin 8, pen is clamped by penholder 3, and fixed by the first scale bolt 1 in left side, along circumferentially moving pen, just can draw the circle of required radius, if when to the cutting or rule of thinner sheet metal component etc., only need to change the pen with unlike material nib and just can realize the function that cuts or rule.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, utilize the technology contents of above-mentioned announcement to make a little change or modify and can become equivalent embodiment, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
