Cis-polybutadiene rubber clamper with adjustable round sliding channel periphery

Abstract

The present invention relates to a glass test clamper, particularly to a cis-polybutadiene rubber clamper with the adjustable round sliding channel periphery, wherein each clamping rule comprises a clamping portion and a sliding portion, and the following improvements are adopted: the sliding portion is positioned at one end of the clamping portion and is overlapped on the upper plane of the clamping portion, the lower surface of the sliding portion is a sliding lower plane, the sliding lower plane is provided with a circular concave groove, a transition concave groove with a symmetrical center is arranged between the circular concave groove and the sliding lower plane, the upper surface of the clamping portion is a clamping upper plane, the clamping upper plane is provided with a circular convex groove, a transition convex strip with a symmetrical center is arranged between the circular convex groove and the clamping upper plane, the sliding lower plane and the clamping upper plane are positioned at the same height, the inner side of the clamping portion is provided with a clamping slope, a rubber pressing sheet is attached on the clamping slope and adopts a synthetic cis-polybutadiene rubber, and the circular concave groove of each edge of the pressing plate and the adjacent circular convex groove form the sliding matching so as to continuously and randomly adjust the tempered glass plates with different widths.

Description

technical field [0001] The invention relates to a glass testing jig, classification number: G01N3 / 04, in particular to such a butadiene rubber jig which can be enlarged or reduced around and used for testing the strength of glass. Background technique [0002] Glass is one of the oldest materials discovered and utilized by man. As early as 3,500 years ago, ancient Egypt had the technology of making simple glassware, and in the tombs of the Western Zhou Dynasty in my country, man-made glass ornaments were also unearthed. With the development of science and technology, glass has developed particularly rapidly in the past one hundred years, and glass has become an indispensable material in human daily life. With the development of economy, the application of glass in all walks of life is more and more extensive. Glass can be used as glass curtain walls, glass doors and windows, etc. in buildings, as teacups, wine bottles, lamps, etc. in consumer goods, and as transparen...

AI Technical Summary

Problems solved by technology

This method is not only inconvenient to operate, but takes a long time, and the adhesive tape is a disposable product, which is easy to cause waste and pollution, and after each test, the adhesive tape residue on the test bench plate 50 must be removed to clean up the broken glass. Otherwise, the remaining glass fragments will affect the next experimental test operation

[0006]At the same time, the adhesive tape may also be broken by the force of the tempered glass explosion, causing the operator to be injured. Therefore, it is necessary to improve the tempered glass fragment test device

[0007] Chinese patent application number: 201420595067.X, test device for tempered glass shards, proposed some new methods and measures to deal with the clamping of brittle glass, but it is still impossible to adjust the size at will, and it is impossible to make the four sides of the platen all in the same on flat surface

At least one side of the patent must not be in contact with the test bench surface

What is referred to as the suspended retaining wall 5 in the embodiment cannot be in contact with the base 1 simultaneously with other three-sided retaining walls, so the retaining piece 4 has to be used to make up the gap between the suspended retaining wall 5 and the base 1, resulting in four Uneven surrounding force

In addition, the width of the baffle 4 itself is fixed, and only multi-piece splicing can be used, and continuous changes of different widths cannot be achieved.
