Tempered glass fragment number detecting and fixing device

Abstract

The invention relates to a tempered glass testing and inspecting device, in particular to a tempered glass fragment number detecting and fixing device. As improved, a bearing slide press plate assembly is fixed on the upper plane of a testing platform, a rolling bearing of a press plate on each side is in sliding fit with a bearing slide on the adjacent side, so that tempered glass plates in different specifications and dimensions can be adjusted continuously and freely; a driving gear is also fixed on a platform rotary shaft on one side and cooperates with a manual gear, the manual gear is rotationally fixed on a manual axle, an axle flange is arranged at the inner end of the manual axle and fixed on the outer side surface of each corresponding plate rack, a shaft snap spring is arranged at the outer end of the manual axle and blocks on the outer side surface of the manual axle, a hand wheel cross bar is fixedly connected onto the hand wheel step circle of the manual gear, and a hand wheel crank handle is also arranged at the outer end of the hand wheel step circle. By the aid of cooperation of stud lock pins and inner hole threads of lock pin supports, tempered glass plates are kept firm in the whole test process.

Description

technical field [0001] The invention relates to a test and inspection device for tempered glass, classification number: G01N3 / 32, in particular to such a device for detecting and fixing the number of tempered glass fragments that can be enlarged or reduced around the pressure plate and uses a reversible workbench to test glass performance indicators . Background technique [0002] Fragmentation test is a main way to detect the quality of tempered glass. According to the requirements of national standards, after the 3mm thick tempered glass is broken, the fragments in any 50*50mm should be more than 30 pieces, and the 4mm~12mm thick tempered glass is broken. Fragments within any 50*50mm should be larger than 40 pieces, and a small amount of long fragments are allowed, the length of which should not exceed 75mm. The direction of the strip-shaped fragments should be roughly parallel to the edge of the glass. If they are not parallel, the included angle should not exceed 45 deg...

Problems solved by technology

This method is not only inconvenient to operate, it 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

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

[0004] Chinese patent application number: 2009203050079, tempered glass falling ball test bench, in order to solve the problem of glass fragments splashing everywhere when tempered glass is used for experiments, the method of supporting frame box is adopted, although it can effectively remove glass fragments, it is inconvenient to read glass fragments , and the installation efficiency of continuous multi-piece tempered glass is low

[0005] China's other patent application number: 201420595067.X, tempered glass shard state test device, proposed some new methods and measures to deal with brittle glass splints, but it is still impossible to adjust any size, and it is impossible to make the four sides of the splints 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.
