Ladder sliding channel four-side sliding bead coplanar aluminum alloy fixing device

Abstract

The invention relates to a glass testing fixing device, in particular to a ladder sliding channel four-side sliding bead coplanar aluminum alloy fixing device. As an improvement, the lower surface of a step of a sliding plate part serves as a lower plane of the sliding plate, a step groove is formed in the lower plane of the sliding plate, and a centrosymmetric transitional groove is formed between the step groove and the lower plane of the sliding plate. The upper surface of a fixed part serves as a fixed upper plane, a step convex rail is arranged on the fixed upper plane, and a centrosymmetric transitional convex strip is arranged between the step convex rail and the fixed upper plane. The lower plane of the sliding plate and the fixed upper plane are located at the same height. A fixed slope is arranged on the inner side of the fixed upper plane, and a rubber pressing sheet is attached to the fixed slope. A sliding ball is fixed in a ball seat step hole in the upper plane of a pressing plate. The outward protruding spherical face of the sliding ball is in contact with the lower plane of the sliding plate, so that the lower plane of the sliding plate in one fixing device slides more smoothly and easily relative to the upper plane of the pressing plate in another fixing device, and it is ensured that the periphery of tested armor plate glass is stressed unevenly.

Description

technical field [0001] The invention relates to a glass testing fixture, classification number: G01N3 / 04, in particular to such an aluminum alloy fixture with sliding balls on four sides and the same plane on the ladder slideway, 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 glass objects, 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 buil...

Problems solved by technology

This method is not only inconvenient to operate, but takes a long time, and the tape is a disposable product, which is easy to cause waste and pollution, and the tape residue on the test bench must be removed after each test to remove 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 fixation 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 on the same plane superior

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.
