Adjustable tungsten alloy pressing plate with slide balls on four edges of chute slide ways on same plane

Abstract

The invention relates to a glass test pressing plate, in particular to an adjustable tungsten alloy pressing plate with slide balls on four edges of chute slide ways on the same plane. As an improvement, the lower surface of a slide plate is a slide plate lower plane. Inclined-face protruding rails are arranged on the slide plate lower plane. The upper surface of a clamping part is a pressing plate upper plane. Inclined-face grooves are formed in the pressing plate upper plane. The slide plate lower plane and the pressing plate upper plane are located at the same height. Fixed slopes are arranged on the inner side of the pressing plate upper plane. Rubber pressing pieces are attached to the fixed slopes. The bottom faces of the inclined-face grooves are groove bottom planes. The lower faces of the inclined-face protruding rails are protruding rail top planes and groove bottom planes. The depth between the pressing plate upper plane and the groove bottom planes is larger than the height between the slide plate lower plane and the protruding rail top planes. Particularly, sliding balls are fixed in ball base step holes in the pressing plate upper plane. The outwards-protruding ball faces of the sliding balls make contact with the sliding plate lower plane so that slippage of the sliding plate lower plane on each fixing device relative to the pressing plate upper plane in another fixing device can be smoother and easier.

Description

technical field [0001] The present invention relates to a glass test pressure plate, classification number: G01N3 / 04, in particular to such a tungsten alloy adjustable pressure plate with sliding balls on four sides of a chute slideway and the same plane for testing the strength of glass, which can be enlarged or reduced in all directions. . 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 ...

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.
