Abstract

The utility model relates to a novel square gauge which belongs to the technical field of the subgroup of compasses of the group of circular curve drawing instruments or similar instruments of the subclass of writing or drawing appliances; writing or drawing auxiliary appliances of the class of office appliances; writing or drawing apparatuses under the subsection of printing in the section of performing operations and transporting according to the International Patent Classification (IPC). The utility model aims to solve the technical problem that only a compass exists and a square gauge does not exist at the past time. The utility model is mainly composed of a handle, a pointer, a transverse beam, a gauge leg, a clip sheet, a screw nail and a pen core. The utility model is characterized in that the gauge leg is clamped at both surfaces of the transverse beam in a connection mode, and the pen core is connected with the middle of the clip sheet in an insertion mode. The utility model has the optimal scheme that stainless steel is used as materials, and the novel square gauge is in large scale production by making use of basal equipment in stationery factories to meet the requirements of students. Thus, the practicability and the economic value of the novel square gauge of the utility model can be better realized.

Description

A kind of novel square gauge

(1) technical field:

The utility model relates to a kind of novel square gauge, divides by International Patent Classification (IPC) (IPC) to belong to operation Department of Transportation, and 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, compasses group

Technical field.

(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 a kind of demand of novel square gauge, also once designed many outstanding technical schemes.As being declared by Sun Li of the Decree of Patent Office of China in 1996, Granted publication number is CN 2224095Y, and China Patent No. (ZL) is: No. 95211950.1 utility model title is the utility model patent of " sucked type educational compasses ", the technical scheme that is adopted.Big group of circular curve plotter or analogous instrument, compasses group technical elements is a routine of great value invention, and it has solved the technical problem of compasses suckers effectively.But still have some deficits, only do not have the technical problem of square gauge before it also is difficult to solve at compasses.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of novel square gauge.Only there not to be the technical problem of square gauge before solving at compasses.

A kind of novel square gauge that the technical scheme that the technical problems to be solved in the utility model adopted is achieved in that this utility model mainly by: handle, pointer, crossbeam, rule pin, intermediate plate, screw, pen core constitute.Its handle, crossbeam, screw, pen core are by selecting for use on the market.Its pointer is the faller gill shape, is material with the iron wire, stretched processing and manufacturing.Its rule pin is a rectangular shape, is material with the stainless steel, through the casting processing and manufacturing.Its intermediate plate is a plate shape, is material with the stainless steel substrates, through the casting processing and manufacturing.

In shape, textural, the total essential features of a kind of novel square gauge of the present utility model and immediate prior art is: handle is threaded in the centre position of crossbeam, constitutes

Fixed in shape structure, function have been that hand is taken effect.Screw thread is connected the centre position of intermediate plate, constitute " Shape bascule, function have been squeezing actions.In shape, textural, a kind of novel square gauge of the utility model technical characterictic different with immediate prior art is: the rule pin is clamped and connected in two face positions of crossbeam, constitutes the flat shape bascule, and function is to play a supportive role.Pen core inserts the centre position that is connected intermediate plate, constitutes the strip bascule, and function has been the setting-out effect.So just realized the former purpose that did not only have the technical problem of square gauge of solution of a kind of novel square gauge of the present utility model at compasses.

The beneficial effect of a kind of novel square gauge of utility model be the utility model be solution in the past only compasses do not have technical scheme that the square gauge technical problem adopted and existing and once had about big group of circular curve plotter or analogous instrument, the technology of compasses group has been compared two place's advantage and improvement:

The first, owing to designed the rule pin in the technical scheme of a kind of novel square gauge of the present utility model, so the technical problem that easier solution is supported.

The second, owing to designed pen core in the technical scheme of a kind of novel square gauge of the present utility model, so easier solution setting-out technical problem.

The label declaration of parts in the schematic diagram:

1 handle, 2 pointers, 3 crossbeams, 4 rule pin

5 intermediate plates, 6 screws, 7 pen cores

(5) specific embodiment:

Below in conjunction with accompanying drawing, be only not have the optimal way of the technical scheme that the technical problem of square gauge takes to be described further before realization solves at compasses to a kind of novel square gauge of the present utility model:

Its static structure: please join accompanying drawing: as shown in the figure, a kind of novel square gauge of the present utility model mainly is made of handle 1, pointer 2, crossbeam 3, rule pin 4, intermediate plate 5, screw 6, pen core 7.Its handle 1, crossbeam 3, screw 6, pen core 7 are by selecting for use on the market.Its pointer 2 is faller gill shapes, is material with the iron wire, stretched processing and manufacturing.Its rule pin 4 is rectangular shapes, is material with the stainless steel, through the casting processing and manufacturing.Its intermediate plate 5 is plate shapes, is material with the stainless steel substrates, through the casting processing and manufacturing.

In shape, textural, the total essential features of a kind of novel square gauge of the present utility model and immediate prior art is: handle 1 is threaded in the centre position of crossbeam 3, constitutes

Fixed in shape structure, function have been that hand is taken effect.Screw 6 is threaded in the centre position of intermediate plate 5, constitutes Shape bascule, function have been squeezing actions.In shape, textural, a kind of novel square gauge of the present utility model technical characterictic different with immediate prior art is: rule pin 4 is clamped and connected in two face positions of crossbeam 3, constitutes the flat shape bascule, and function is to play a supportive role.Pen core 7 inserts the centre position that is connected intermediate plate 5, constitutes the strip bascule, and function has been the setting-out effect.

Its dynamic structure: in the optimal way of implementing, in use, when determining linear distance, regulates two distances of advising 4 on pin, according to physics principle, its rule pin 4 acts on crossbeam 3 by pointer 2, thus finish roll adjustment from task.

Its dynamic structure: in the optimal way of implementing, in use, in the time of setting-out, the adept handle 1 of hand allows two pen cores 7 move simultaneously, the lines that draw, and according to geometrical principle, its rule pin 4 acts on pen core 7 by intermediate plate 5, thereby finishes the task of setting-out.So just realized the former technical problem purpose that did not only have square gauge of solution tradition of a kind of novel square gauge of the present utility model at compasses.

Realize that preferred plan of the present utility model is is material with the stainless steel, utilize the basic equipment of stationery factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of a kind of novel square gauge of the present utility model better with the demand of supply student circle.
