Abstract

A pulley-type compass belongs to the printing branch department, operation and transportation department, writing or plotting instrument of writing or plotting assistant appliance under the office appliance, compass group under the circular curve plotter or the similar instrument group technical field according to the international patent classification scheme. The purpose is to resolve the technical problem that the needlepoint of the compass is easy to break the paper and is uneasy to rotate. The pulley-type compass mainly comprises a plastic board, a base seat, a nib slot, scale ruler, a sliding groove, a needlepoint, wherein, the upper portion of the needlepoint is welded on the middle portion of the sliding groove, and the lower portion of the needlepoint is inserted into the middle portion of the base seat. The pulley-type compass is applicable for practical new technical scheme in the compass group under the circular curve plotter or the similar instrument group technical field with wide application, simple manufacture, low cost, convenient use and easy popularization.

Description

The pulley-type compasses
(1) technical field:
The utility model relates to the pulley-type compasses, belong to operation, Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch, write or drawing appliance, the big class of office appliance is write drawing article, the assistant product group of writing or draw, big group of circular curve plotter or analogous instrument, the technical field of compasses group.
(2) background technology:
At present, existing and once had about big group of circular curve plotter or analogous instrument, the technology of compasses group was all done very fruitful effort to the demand of pulley-type compasses, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Zhao Zhengping, Granted publication number is CN2224097Y, China Patent No. (ZL) is: 95214560.X number utility model patent title is the utility model patent of " from rectilinear compasses ", the technical scheme that is adopted.Big group of circular curve plotter or analogous instrument, the technical elements of compasses group are routine of great value inventions, and it has solved compasses effectively from rectilinear technical problem.But still have some deficits, it also is difficult to solve the compasses needle point and easily punctures paper, is difficult for the technical problem of rotating.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of pulley-type compasses.Easily puncture paper to solve the compasses needle point, be difficult for the technical problem of rotating.
The pulley-type compasses that the new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that this utility model mainly by: plastic plate, base, nib slot, rule, chute, needle point constitute.Its major part plastic plate, rule, needle point are selected for use by market.Its nib slot is a drum, is material with the steel, through polishing, and the boring processing and manufacturing.Its base is the pyrometric cone shape, is material with rubber, through cutting, perforation processing manufacturing.
In shape, structure and combination thereof, the total essential features of pulley-type compasses of the present utility model and immediate prior art is: the location about clamping of nib slot is connected the centre position of chute, the sticking card of the lower position of chute is connected the top point midway of plastic plate, be combined into the external and internal compositions of four word shapes, function has been to load nib, determines the effect of radius length.The sticking card of the lower position of rule is connected the upper position of plastic plate, is combined into OBL up-down structure, and function has been the effect of definite radius length.In shape, structure and combination thereof, the pulley-type compasses of the present utility model technical characterictic different with immediate prior art is: the upper position of needle point is welded to connect the centre position at chute, the lower position of needle point inserts the centre position that is connected base, be combined into up-down structure, function has been the effect of definite home position.The solution compasses needle point of so just having realized pulley-type compasses of the present utility model easily punctures paper, is difficult for the purpose of the technical problem of rotation.
The beneficial effect of the pulley-type compasses of utility model is: the utility model easily punctures paper for solving the compasses needle point, the technical scheme that technical problem adopted of be difficult for rotating and existing and once had about big group of circular curve plotter or analogous instrument, the technology of compasses group has been compared an advantage and improvement:
First, be welded to connect centre position owing to designed the upper position of needle point in the technical scheme of pulley-type compasses of the present utility model at chute, the lower position of needle point inserts the centre position that is connected base, be combined into up-down structure, so can easier solution determine the technical problem of home position.
(4) description of drawings:
Accompanying drawing provides the structural representation of pulley-type compasses of the present utility model:
Fig. 1: the Facad structure schematic diagram that is pulley-type compasses of the present utility model:
Fig. 2: the plan structure schematic diagram that is pulley-type compasses of the present utility model:
The label declaration of parts in the schematic diagram:
1 plastic plate, 2 bases, 3 nib slots, 4 rules, 5 chutes, 6 needle points
(5) specific embodiment:
Below in conjunction with accompanying drawing, for realizing that solving the compasses needle point easily punctures paper, the optimal way of the technical scheme that the technical problem that is difficult for rotating is taked is described further to pulley-type compasses of the present utility model:
Its static structure: please join accompanying drawing: as shown in the figure, pulley-type compasses of the present utility model mainly are made of plastic plate 1, base 2, nib slot 3, rule 4, chute 5, needle point 6.Its major part plastic plate 1, rule 4, needle point 6 are selected for use by market.Its nib slot 3 is drums, is material with the steel, through polishing, and the boring processing and manufacturing.Its base 2 is pyrometric cone shapes, is material with rubber, through cutting, perforation processing manufacturing.
In shape, structure and combination thereof, the total essential features of pulley-type compasses of the present utility model and immediate prior art is: the location about clamping of nib slot 3 is connected the centre position of chute 5, the sticking card of the lower position of chute 5 is connected the top point midway of plastic plate 1, be combined into the external and internal compositions of four word shapes, function has been to load nib, determines the effect of radius length.The sticking card of the lower position of rule 4 is connected the upper position of plastic plate 1, is combined into OBL up-down structure, and function has been the effect of definite radius length.In shape, structure and combination thereof, the pulley-type compasses of the present utility model technical characterictic different with immediate prior art is: the upper position of needle point 6 is welded to connect the centre position at chute 5, the lower position of needle point 6 inserts the centre position that is connected base 2, be combined into up-down structure, function has been the effect of definite home position.
Below by using method, further set forth the dynamic structure relation of these practical pulley-type compasses: in use, in the time of needs picture circle, at first determining home position with needle point 6 bases 2, determine radius paddling nib slot 3 then, rotate plastic plate 1 more then, thereby finish the task of picture circle.The solution compasses needle point of so just having realized pulley-type compasses of the present utility model easily punctures paper, is difficult for the purpose of the technical problem of rotation.
Realize that preferred plan of the present utility model is is material to draw circle, utilize the basic equipment of plastic processing factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of pulley-type compasses of the present utility model better with the demand of supply educational circles.
