Detailed description of the invention
In order to technical scheme is explained further, below by specific embodiment, the present invention will be described in detail.
As Figure 1-3 for a kind of compasses that can use on any smooth surface that the present invention relates to, mainly include compasses head 1 and the first supporting leg 2 and the second supporting leg 3 being hingedly bearing on compasses head 1, first supporting leg 2 is provided with drafting parts, providing these drafting parts 4 in embodiment is pencil, the chalk etc. being contained on installation portion, can be as purposes such as teaching, certainly, owing to compasses of the present invention can use on any smooth surface, thus shown drafting parts may be replaced by diamond knife, icking tool etc. can be with the cutter of the material such as glass-cutting or ceramic tile.
Described second supporting leg 3 is provided with adjustable positioning mechanism 5, and this adjustable positioning mechanism 5 mainly includes sucker 51 and a center pin 52；Seeing Fig. 3, the lower end of the second supporting leg 3 offers the regulating tank 31 that a groove depth extends and bottom is opening-like along the second supporting leg 3 length direction, and the groove depth value of this condition groove 31 can make relative set according to center pin 52；Center pin 52 is telescopically assembled in regulating tank 31, and sucker 51 is rotatably set at the underpart opening of regulating tank 31, and the center of sucker 51 offers the centre bore 511 passed for center pin 52.Combining accompanying drawing below for the assembling mode of sucker 51, center pin 52 and provide a concrete preferred embodiment, it is not limited only to given embodiment certainly, will not enumerate here.
Described sucker 51, use rubber plastic material, it is set in the opening part of regulating tank 31 by an adapter sleeve 53, and adapter sleeve 53 is a bearing holder (housing, cover) run through, and its medial wall offers a cannelure 531, the lateral wall of regulating tank 31 is correspondingly provided with convex grain 32, this convex grain 32 is appropriately embedded in cannelure 531, and rotation of can sliding in cannelure 531, thus under sucker 51 adsorbs positioning scenarios, second supporting leg 3 coordinates via convex grain 32 and cannelure 531, it is possible to spinning movement made by sucker 51 relatively.Further, sucker 51 could be arranged to disassembled form, offers breach 532 in the upside of the corresponding cannelure 531 of adapter sleeve 53, and its embedding being not only convenient for convex grain 32 is arranged, being also convenient for the disassembling section of convex grain 32, thus making adapter sleeve 53 and relative second supporting leg 3 of sucker 51 is disassembled assembling.
Described center pin 52, its lower end is formed as a needle point 521, and upper end side is provided with tooth bar 522；The circular in cross-section shape of center pin 52, corresponding regulating tank 31 is in suitable cylinder-like structure, and the corresponding adaptation of center pin 52 is plugged in regulating tank 31；On described second supporting leg 3, the side of corresponding regulating tank 31 offers a connected entrance, a gear 54 it is equiped with at this connected entrance, this gear 54 is suitable with the tooth bar 522 of center pin 52 engages setting, additionally, for the stability after making the smooth and easy of center pin 52 expanding-contracting action and guaranteeing its flexible location, the lock screw 55 for holding out against center pin 52 also can be provided with on position relative with gear 522 on the second supporting leg 3, when making expanding-contracting action, can correspondence outward winding lock screw 55, behind flexible location, then cycle lock screw 55 holds out against again.
nullThus，A kind of compasses that can use on any smooth surface of the present invention，It is provided with adjustable positioning mechanism 5 on the second supporting leg 3，Sucker 51 that this governor motion 5 includes can be adsorbed on any smooth surface and telescopically adjustable center pin 52，During operation，Operation gear 54，The needle point 521 making center pin 52 the most suitably stretches out outside sucker 51，The drafting center of circle is determined by this needle point 521，Operate gear 54 the most again and regulate center pin 52 retraction sucker 51，It is adsorbed in smooth flat by sucker 51 correspondence simultaneously，Relative second supporting leg 3 of first supporting leg 2 opens suitable angle，Rotate compasses head 1，Required circle or arc structure can be drawn out by drawing parts，Owing to using the absorption of sucker 51 precise positioning，Compasses of the present invention are highly stable in operating does not haves skidding，Can be in any form、Use on the smooth surface of any position，And replaced traditional round compass needle to position by sucker 51，Avoid and leave pin hole or hole vestige from the teeth outwards，Without destroying problem.
To sum up, compasses of the present invention overcome and there is practicality deficiency in prior art and have certain destructive defect, have the advantages such as accurate, stable, safe, and the multi-field application for compasses provides a kind of new approaches.Additionally, when required picture or draw the circle put or arc chord angle little time, can also be by changing the little sucker of circular diameter, when not drawing on smooth surface, sucker 51 can also be unloaded, use, when not in use as conventional compasses, center pin 52 can also be entirely retracted in regulating tank 31, to avoid damage center pin or to stab human body etc..
Above-described embodiment and the product form of the graphic and non-limiting present invention and style, suitably change that it is done by any person of an ordinary skill in the technical field or modify, all should be regarded as the patent category without departing from the present invention.
