Description

Technical Field

[0001] The utility model relates to the technical field of counting tooling, in particular to a tempered glass fragment counting frame. Background Art

[0002] At present, wind spots can be qualitatively judged by polarized light to determine whether the glass is tempered. Experienced people can also identify whether it is tempered glass by flatness plus side light, but this often has limitations. In addition, you can break the tempered glass and check the broken particles to confirm whether it is tempered glass, but this is destructive and is the only standard that can accurately judge tempered glass so far. As a type of architectural safety glass, tempered glass has become a widely used building material and raw material. Therefore, the state of the fragments is an important performance of tempered glass and a basis for judging the safety performance of the product. It is widely valued by manufacturers and users, and is included in the mandatory product certification of architectural tempered glass.

[0003] According to the national standard test method, 4 glass samples are taken for testing. The minimum number of fragments in any 50mm×50mm area of ​​each sample must meet the test requirements. At a position about 20mm away from the periphery on the center line of the longest side of the sample, use a small hammer or punch with a tip curvature radius of 0.2mm+0.05mm to impact and break the sample. Measures to retain the fragment pattern should start 10s after the impact and end within 3min after the impact. When counting the fragments, the part within 80mm radius from the impact point and 25mm from the edge of the glass or the edge of the drill hole should be removed. Within the range of 50mm×50mm, the number of fragments at the maximum position should not be less than a certain value, and there should be no long strip fragments with a length of more than 75mm without through cracks at any position of the glass.

[0004] At present, the counting frame of tempered glass fragment status can only draw a 50mm*50mm counting area. The part within the 80mm radius of the impact point and the 25mm range from the edge of the glass or the edge of the drill hole required by the standard is not used as the counting area and cannot be measured in the counting frame. It can only be measured with a steel ruler or steel tape measure alone. When selecting the maximum position of the fragment, multiple ranges need to be confirmed. If a steel ruler or steel tape measure is used alone for multiple measurements, the detection time will be prolonged, which will affect the detection efficiency. As time goes by, the fragment will split from one into two or more, which will affect the detection results. Utility Model Content

Figure 2 ), or it can be flipped to the right to dock with the data frame (as shown Figure 3 The counting frame body 1 is fan-shaped, the counting frame body 1 is a quarter-circle fan-shaped, and the lengths of the two straight sides of the counting frame body 1 are both 80 mm. The counting frame body 1 adopts a 1 / 4 circle shape with a radius of 80 mm, and can quickly determine the range with the impact point as the center and a radius of 80 mm.

[0024] A first counting frame 5 is provided inside the counting frame body 1. The first counting frame 5 is a square with a side length of 50 mm. It can reflect a counting area of ​​50 mm*50 mm on the tempered glass. The thickness of the folding ruler 4, the thickness of the counting frame body 1, and the thickness of the first counting frame 5 are consistent.

[0025] The width of the folding ruler 4 is 20mm, and the adjacent two sides of the first counting frame 5 are 5mm away from the two straight sides of the fan-shaped counting frame body 1. One end of the folding ruler 4 in the extension direction is a straight side, and the other end is an arc-shaped side overlapping the fan-shaped side of the counting frame. The length of the folding ruler 4 is 80mm. The straight sides of the counting frame and the straight sides of the folding ruler 4 are both provided with length scales, and the minimum scale is 1mm. The distance between the edge of the 50mm*50mm range and the outermost edge is 25mm. When used to measure the distance between a 50mm*50mm square and an edge, the folding ruler 4 is flipped downward to open a 50mm*50mm square side parallel to it to form a ruler with a width of 25mm. The counting frame body 1 is placed on the sample, and the folding ruler 4 part (such as Figure 2 If there are long strips of fragments with a length greater than 75 mm and no through cracks on the sample, the folding ruler 4 can be turned right (as shown). Figure 3 As shown in the figure, a ruler with a length of 160 mm is assembled with the counting frame to measure the length of the long strip fragments.

[0026] A circular hole 7 is provided at one end of the counting frame body 1 close to the sector edge, 3 mm away from the sector edge and the right-angled side.
