Description

Napier's compasses

The utility model relates to Napier's compasses.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), printing branch, and writing maybe can the figure utensil, and the big class of office appliance is write or drawing article, the assistant product group of writing or draw, the compasses technical group field in circular curve drawing instrument or the analogous instrument.Be numbered B4 3L9/02.

At present, the technology about the compasses in circular curve drawing instrument or the analogous instrument existing and that once had was all done very fruitful effort to the demand of multifunctional compass, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1994 by Deng Guoxing, Granted publication number is CN2179272Y, China Patent No. (ZL) is: 92237953.X number 2 New Names are utility model patents of vernier type multipurpose compasses, the technical scheme that is adopted, compasses technical elements in circular curve drawing instrument or analogous instrument is a routine of great value invention, and it has solved the problem of the accuracy in the compasses drawing effectively.But still have some deficits, it also is difficult to solve the multifunction of compasses and the diversified problem of drawing pen.

The purpose of this utility model is to provide one and Napier's compasses.With the multifunction of solution compasses and the diversified problem of drawing pen.

The purpose of this utility model is achieved in that this utility model Napier's compasses.Mainly constitute by rubber, compass, arc rule, general-purpose pen clip device, back shaft, stroke leg, bundle leg, pen clip pin, spring, trip bolt.Its major part rubber, arc rule, compass, spring, trip bolt are by selecting for use on the market.General-purpose pen clip device steel is material machined manufacturing.The rotary head portion of compasses is a rubber, the attached compass of rotating clip, be fitted with on prick leg on the arc rule and can directly read two bundle leg spacings from the curved scale chi, be connected with two back shafts in stroke midleg processing, general-purpose pen clip device is fixed with back shaft, roller bearing rotates, four following holes are arranged on the general-purpose pen clip device, can put different pens, use the bottom hollow hole of pen clip pin and spring, stroke leg, different pens can be put into the hole, with the fixing figure that draws of trip bolt.So just realized the purpose of this utility model.

The utility model has been compared two advantages and improvement with the original circular curve drawing instrument or the technology of the compasses in the analogous instrument;

The first, because the utility model has designed general-purpose pen clip device in technical scheme, can exchange a plurality of nibs easily for and use as required;

The second, because the utility model has designed the arc rule, the right-hand rule spacing of just directly reading in technical scheme.Thereby the multifunction of compasses and the diversified problem of drawing pen just can have more effectively been solved.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1: be side structure schematic diagram of the present utility model:

Fig. 2: be to want craftsman's general-purpose pen clip device to look up structural representation:

Fig. 3: be of the present utility model stroke of shank separation structure schematic diagram:

The numbering of parts explanation in the schematic diagram: (1) rubber (2) compass (3) arc rule (4) general-purpose pen clip device (5) back shaft (6) is drawn leg (7) and is pricked leg (8) pen clip pin (9) spring (10) trip bolt

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, the utility model Napier's compasses. Mainly by rubber (1), compass (2), Arc rule (3), Universal pen binder (4), back shaft (5), draw leg (6), prick leg (7), Pen clip pin (8), spring (9), trip bolt (10) consist of. Its major part rubber (1), Arc rule (3), compass (2), spring (9), trip bolt (10) are by selecting on the market With. Universal pen binder (4) is material machined manufacturing with steel. The rotary head section of compasses be a rubber ( 1), the attached compass of rotating clip (2), on prick leg (7), be fitted with an arc rule ( 3) can from arc rule (3), directly read two bundle leg (7) spacings, draw leg (6) middle part Processing is connected with two back shafts (5), and Universal pen binder (4) is fixing with back shaft (5), rolls Axle rotates, and four lower holes are arranged on the Universal pen binder (4), can put different pens, usefulness pen clip pin ( 8) and spring (9), draw the bottom hollow hole of leg (6), different pens can be put into the hole, with tight Gu the fixing figure that draws of screw (10). So just realized the purpose of this utility model. Thereby just can solve The multifunction of compasses and the diversified problem of drawing pen.

Below by embodiment, the utility model is done more detailed description:

Embodiment 1, in use, if trip bolt (10) is unclamped in change-fountain pen, compasses turned around, draw back pen clip pin (8), pen clip is kept well, rotate general-purpose pen clip device (4), according to required, compasses are just come, unclamp pen clip pin (8), pen clip is put down, fix with trip bolt (10) and get final product.

Embodiment 2, according to the scale of arc rule (3) directly read two rule between distance.Thereby just can realize the purpose of this utility model.

Realize that preferred plan of the present utility model is is material with the steel, utilize the basic equipment of machining factory, take to assemble in batch to produce by batch, the demand with supply student learning life so just can realize practical value of the present utility model and economic worth better.
