Plate wheel nickel-based platen thread lock pin step clamping plate glass verifying device

Abstract

The invention relates to a toughened glass test and examination apparatus, which discloses a plate wheel nickel-based platen thread lock pin step clamping plate glass verifying device. For improvement: a step slideway clamping plate assembly is fixed on a plane of a test platen, platen rotating shafts are arranged at two sides of the test platen, a hand-operated plate wheel is fixed on the platen rotating shaft at one side, a plate wheel crank handle is arranged on a lateral surface of the hand-operated plate wheel; an outside thread of a thread lock pin is cooperated to a bore screw thread of a lock pin bearer, the lock pin bearer is fixed on the plane on plate-type frames, cylinder ball ends at ends of the thread lock pin can penetrate into lockholes of a spiral cone column at two sides of the test platen; the hand-operated plate wheel drives the test platen for arrangement in a reversible structure, broken glass pieces can be conveniently removed, a recovery container for broken glass pieces is prepared, broken glass pieces cannot be scattered; the thread lock pin is cooperated to the bore screw thread of the lock pin bearer, self-locking defect of the hand-operated plate wheel can be overcome, so that steadiness and firmness of the toughened glass plate during a whole test plate can be kept.

Description

technical field [0001] The invention relates to a test and inspection device for tempered glass, in particular to a disc-wheel nickel-based platform thread lock pin stepped plywood glass inspection device which can be enlarged or reduced around the splint and uses a reversible workbench to test the performance index of the glass. device. 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 degrees. If one...

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.
