Natural rubber press plate with four edges capable of being adjusted to one plane through skewed slots

Abstract

The invention relates to a press plate for glass testing, and especially relates to a natural rubber press plate with four edges capable of being adjusted to one plane through skewed slots. The press plate is composed of a clamping part and a sliding part. The improvements of the press plate are as follows: the sliding part is arranged on one end of the clamping part and is overlapped on the upper surface of the clamping part; the lower surface of the sliding part is taken as the sliding lower plane, the sliding lower plane is provided with a trapezoidal emboss, the upper surface of the clamping part is the clamping upper plane, and the clamping upper plane is provided with a trapezoidal groove. The sliding lower plane and the clamping upper plane are in the same height. The inner side of the clamping part is provided with a clamping slope, and a rubber press sheet is adhered on the clamping slope. The angle between clamping slope (15) and the clamping upper plane (16) is 51 to 53 degrees. A layer of rubber press sheet (51) is adhered on the clamping slope (15), and the thickness of the rubber press sheet (51) is 2.1 to 2.3 millimeters. When the width is adjusted to limit a tempered glass sheet (100) in the horizontal direction, and a downward force can be generated at the same time, so the tempered glass sheet (100) can be pressed against the flat plate (50) of a test platform so as to avoid the explosion of the tempered glass sheet (100) due to the uneven stress on the tempered glass sheet (100).

Description

technical field [0001] The invention relates to a glass testing press plate, classification number: G01N3 / 04, in particular to such a natural rubber press plate with four sides of a chute that can be enlarged or reduced 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 goo...

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, tempered glass shard state test device, proposed some new methods and measures to deal with the clamping of brittle glass, but it still cannot be done It cannot be adjusted to any size, and it is impossible to make the four side pressure plates on the same plane

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.
