Vertical surface round slideway four-side adjustable styrene butadiene rubber pressure plate

Abstract

The invention relates to a fixed pressure plate for a fixed brittle thin plate. Each pressure plate of the provided styrene butadiene rubber pressure plate is composed of a clamping section and a slipping section. A round protruding groove is arranged in an inner side surface of a slideway vertical plate, and a centrosymmetric transition protruding strip is arranged between the round protruding groove and a slipping lower plane. A round recessed groove is arranged in a clamping outer vertical surface, and a centrosymmetric transition recessed groove is arranged between the round recess groove and the clamping outer vertical surface. The round recessed groove in the first clamping section is in sliding cooperation with the round protruding grove in the fourth slipping section. The round recessed groove in the fourth clamping section is in sliding cooperation with the round protruding groove in the third slipping section. The round protruding groove of each pressure plate is in sliding cooperation with the adjacent round recessed groove, continuous and free adjustment of tempered glass plates with different widths can be achieved, and through screw thread cooperation of protruding lug screw holes in the slipping horizontal plates and fastening screws, the satiation is ensured that all the slipping sections can be fixed on clamping upper planes of adjacent clamping sections.

Description

technical field [0001] The invention relates to a special fixing plate for fixing brittle thin plates, classification number: G01N3 / 04, especially relates to such a kind of styrene-butadiene rubber with four sides of the vertical circular slideway that can be enlarged or reduced and used for testing the strength of glass. platen. Background technique [0002] Since May 1, 2003, my country has implemented a mandatory inspection system for safety glass used in automobiles, trains, and buildings. Safety glass products that have not obtained a compulsory product certification certificate and have not applied a China Compulsory Product Certification mark are not allowed to leave the factory , import and sale. [0003] The existing tempered glass fragment test method is to place the tempered glass sample freely on the test bench, and use scotch tape paper or other methods to constrain the glass periphery, or cover the tempered glass with a film to prevent the glass fragments fro...

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

[0004] At the same time, the adhesive tape is also likely to be broken by the force of the tempered glass explosion, causing the operator to be injured. Therefore, it is very necessary to improve the tempered glass fragment test device

[0005] Chinese patent number: 201420795683X, a clamping fixture for ball head assembly processing, this fixture can clamp special parts such as ball heads, but it is not suitable for fixing brittle thin plate materials like glass

China Patent No.: 021226253, the glass substrate fixed seat, uses vacuum negative pressure to fix the glass plate, although it does not directly damage the glass plate, but when doing destructive strength testing, its vacuum negative pressure contact parts will seriously affect the unevenness of the test Therefore, it cannot be used in destructive strength testing of glass plates

Chinese patent application number: 201420595067.X, test device for tempered glass fragments, 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.
