Description

Trapezoidal piece is examined to granite length

Technical Field

The utility model belongs to the technical field of the measuring tool is rectified, especially, relate to a trapezoidal piece is examined to granite length check.

Background

With the development of granite industry, people have higher and higher requirements on precision, how to improve the accuracy of detection, reduce measurement errors and improve the precision of products, and detection tools are continuously improved in practice.

The existing measuring ruler has low precision and high error, and after the error of a measuring tool used for a long time is increased, the requirement of processing cannot be met and a new measuring tool needs to be replaced in time.

Therefore, the invention is very necessary to invent the trapezoidal block for checking the length of the granite.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a trapezoidal piece is examined in granite length school to it is low to solve current granite and detect the precision, and the error is high, and the measuring tool error grow of long-term use can not satisfy the problem that the measuring tool that the processing demand will in time be renewed. A trapezoidal block for checking the length of granite comprises a scale body, lightening holes, a first boss, a first groove, a second boss, a second groove, a third boss, a third groove and a fourth boss, wherein the scale body is a cuboid; a plurality of lightening holes are adopted; the first boss, the first groove, the second boss, the second groove, the third boss, the third groove and the fourth boss are sequentially arranged at the top of the scale body from left to right.

The sizes of the first boss, the second boss, the third boss and the fourth boss are respectively 200mm, 300mm, 400mm and 500mm, and the device can be used for checking accuracy errors of the external card.

The sizes of the first groove, the second groove and the third groove are respectively 100mm, 200mm and 300mm, and the inner card precision error checking device can be used for checking the inner card precision error.

The lightening holes are round through holes and are sequentially arranged on the scale body from left to right, so that the whole weight of the scale body is reduced, and the scale is light in size and easy to take and hang.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses, the standard of first recess, second recess and third recess can be used to the check inside callipers precision error.

2. The utility model discloses, the standard of first boss, second boss, third boss and fourth boss can be used to the outer card precision error of length measuring tools such as school inspection slide caliper rule, steel tape measure, compares out the measuring error of corresponding measuring tool and with the attached measuring tool of label, compensate when using and go into and draw the true value.

3. The utility model discloses, the lightening hole has alleviateed the whole weight of scale body for the scale volume is slim and graceful, easily takes and hangs and put.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure:

1-scale body, 2-lightening hole, 3-first boss, 4-first groove, 5-second boss, 6-second groove, 7-third boss, 8-third groove, and 9-fourth boss.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

example (b):

as shown in figure 1

The utility model provides a trapezoidal piece is examined to granite length, including scale body 1, lightening hole 2, first boss 3, first recess 4, second boss 5, second recess 6, third boss 7, third recess 8 and fourth boss 9, scale body 1 set up to the cuboid; a plurality of lightening holes 2 are adopted; the scale comprises a scale body 1 and is characterized in that a first boss 3, a first groove 4, a second boss 5, a second groove 6, a third boss 7, a third groove 8 and a fourth boss 9 are sequentially arranged at the top of the scale body from left to right.

The sizes of the first boss 3, the second boss 5, the third boss 7 and the fourth boss 9 are respectively 200mm, 300mm, 400mm and 500mm, and the device can be used for checking the accuracy errors of the outer card.

The sizes of the first groove 4, the second groove 6 and the third groove 8 are respectively 100mm, 200mm and 300mm, and the inner card precision error checking device can be used for checking the inner card precision error.

The lightening holes 2 are arranged as circular through holes and are sequentially arranged on the scale body 1 from left to right, so that the whole weight of the scale body 1 is reduced, and the scale is light in size and easy to take and hang.

Principle of operation

The utility model discloses in, first recess 4, the standard of second recess 6 and third recess 8 can be used to the school and examine inside callipers precision error, first boss 3, second boss 5, the standard of third boss 7 and fourth boss 9 can be used to the school and examine slide caliper rule, the outer card precision error of length measuring tools such as steel tape measure, the measuring error of comparing out corresponding measuring tool is attached to the measuring tool with the label on, the compensation is gone into when using and is reachd the truth value, the lightening hole has alleviateed scale body 1's whole weight, make the scale volume merrily and lightheartedly, easily take and hang and put.

Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
