Abstract
The utility model relates to a portable ruler and belongs to the ministry of operation transport, the brushing printing subsection, the writing or drawing implement, the office appliance broad categories, the writing or drawing appliance, the writing or drawing assistant appliance subclass, the round curve plotter or similar instrument jumpbogroup, and the compasses group technical field. The class number is B 4 3 L 9 / 0 2. The utility model comprises an angle gauge, scale marks, nails, and holes, and is characterized in that the scale marks are nicked on the bottom edge position of the angle gauge, the nails are equipped on the left lower position of the angle gauge, and the holes are equipped on the lower side position of the angle gauge. The utility model is a portable ruler with practical value.
Description
The utility model relates to Convenient rule.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance, the big class of office appliance is write or drawing article, the assistant product group of writing or draw, big group of circular curve plotter or analogous instrument, the compasses technical group field.Classification number is B43L9/02.
At present, existing and once had about big group of circular curve plotter or analogous instrument, the technology of compasses was all done very fruitful effort to the demand of Convenient rule, also once designed many outstanding technical schemes.As being declared by Mai Shiyong of the Decree of Patent Office of China in 1996, Granted publication number is CN2242797Y, and China Patent No. (ZL) is: No. 95246265.6 utility model title is the utility model patent of " Pencil compasses on desk ", the technical scheme that is adopted.Big group of circular curve plotter or analogous instrument, the compasses technical elements is a routine of great value invention, and it has solved the problem of Pencil compasses on desk effectively.But still have some deficits, it also is difficult to solve protractor function problem very little.
The purpose of this utility model is to provide a kind of Convenient rule.To solve protractor function problem very little.
The purpose of this utility model is achieved in that this utility model Convenient rule.Mainly constitute by protractor, scale, wire nail, hole.Its protractor is a semi-circular shape, uses plastic material, through the thermoforming processing and manufacturing.Its wire nail is a cylindrical shape, uses plastic material, through the thermoforming processing and manufacturing.Scale adopts the groove method to be engraved in the position, base of protractor, constitutes shallow slot shape reticle structure, and function has been to survey the length effect.Wire nail adopts the interference fit method to be installed in the position, lower-left of protractor, constitutes the outstanding structure of cylindrical shape, and function has been the centering effect.The hole adopts drilling method to be installed in the lower position of protractor, constitutes the toroidal pore structure, and function has been the effect of picture circle.So just realized the purpose of this utility model.
The advantage of utility model: big group of the utility model and original circular curve plotter or analogous instrument, the compasses technology has been compared three advantages and improvement;
The first, because the utility model has designed wire nail in technical scheme, so can be used for the picture circle;
The second, because the utility model has designed protractor in technical scheme, so can take measurement of an angle;
The 3rd, because the utility model has designed scale in technical scheme, so can survey length; Thereby just can more effectively solve protractor function problem very little.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the agent structure schematic diagram of the utility model Convenient rule;
Fig. 2 is the A-A cross-sectional view of the utility model Convenient rule;
The numbering of parts explanation in the schematic diagram: 1 protractor, 2 scales, 3 wire nails, 4 holes
In the optimum implementation of the utility model Convenient rule, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:
Its static structure: as shown in the figure, the utility model Convenient rule.Mainly constitute by protractor 1, scale 2, wire nail 3, hole 4.Scale 2 adopts the groove method to be engraved in the position, base of protractor 1, constitutes shallow slot shape reticle structure, and function has been to survey the length effect.Wire nail 3 adopts the interference fit method to be installed in the position, lower-left of protractor 1, constitutes the outstanding structure of cylindrical shape, and function has been the centering effect.Hole 4 adopts drilling method to be installed in the lower position of protractor 1, constitutes the toroidal pore structure, and function has been the effect of picture circle.
Its dynamic structure: in force:
Its wire nail 3 acts on protractor 1 by interference, thereby finishes the task in the center of circle, location.So just realized the purpose of this utility model.Thereby just can solve protractor function problem very little.
Below by using method, the utility model is done more detailed description:
This utility model Convenient rule is work like this:
In use, when doing one's assignment, except can taking measurement of an angle as common protractor, scale 2 on the base makes and can measure length with it, with wire nail 3 location, around wire nail 3, can draw by hole 4 and to specify the circle or the circular arc of radius, not only convenient but also accurate.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of stationery factory, take thermoforming to produce in batch, the demand with supply student circle so just can realize practical value of the present utility model and economic worth better.
