Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass technology, specifically to a glass plate impact resistance testing device. Background Technology
[0002] The falling ball impact test is a common experimental method for verifying the impact resistance of glass plates. In existing technology, the procedure for manually conducting the falling ball impact test is as follows: the glass plate is placed on a test chamber, and a person stands on an A-frame ladder, measuring the vertical distance to the glass plate with a measuring tape. A steel ball is then allowed to fall freely from a predetermined distance, impacting the glass plate directly below. If the glass plate does not break, its strength meets the requirements. The standard weight of the steel ball used in the test is 1040g, with a diameter of 63.5mm, and the drop height varies depending on the thickness of the glass plate.
[0003] In the experiment, the ball is required to land at the center of the glass plate. However, it is difficult to ensure that the steel ball is centered when conducting the drop ball impact test manually. Furthermore, measuring the height of the steel ball manually with a measuring tape is inconvenient and results in significant measurement errors, leading to substandard drop ball heights. Therefore, the current manual drop ball impact test suffers from significant human error, and the accuracy of the experimental results needs to be improved. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a glass plate impact resistance testing device to solve the technical problems of large experimental result errors and insufficient operation convenience in manual glass plate drop ball impact testing.
[0005] This utility model glass plate impact resistance testing device includes a horizontal base plate, a rectangular counting frame fixed on the horizontal base plate, a rectangular pressing frame for pressing down the glass plate, an inclined ladder fixed on the horizontal base plate, a horizontal base plate fixed on the inclined ladder frame and located above the rectangular counting frame, and a ball drop tube vertically arranged on the horizontal base plate. The center of the ball drop tube is directly opposite the center of the rectangular counting frame. The side of the ball drop tube is provided with a ball release hole, and the side of the ball drop tube is also provided with an elevation value marking the height of the ball release hole.
[0006] Furthermore, the rectangular counting frame is provided with a shock-absorbing rubber ring at its opening.
[0007] Furthermore, a positioning sleeve is vertically fixed in the middle of the horizontal base plate, and the ball drop tube is inserted into the positioning sleeve.
[0008] Furthermore, the distances from the ball release hole to the plane of the counting frame opening are 1200mm, 1500mm, 1900mm, 2400mm, 3000mm and 3800mm, respectively.
[0009] The beneficial effects of this utility model are:
[0010] 1. The glass plate impact resistance testing device of this utility model can ensure that the test ball falls freely from the standard measurement height to the middle of the glass plate being tested, which can reduce the operation error of the manual ball drop test and improve the accuracy of the results of the manual ball drop test.

The center of the ball drop tube is directly opposite the center of the rectangular counting frame. A ball release hole 7 is provided on the side of the ball drop tube, and an elevation value 8 marking the height of the ball release hole is also provided on the side of the ball drop tube.
[0015] The method for conducting the experiment using the glass plate impact resistance testing device in this embodiment is as follows:
[0016] The glass plate to be tested is placed on the opening of the rectangular counting frame 2, and then the rectangular pressing frame 3 is placed on the glass plate to hold it in place. The tester then climbs the inclined ladder and places the test ball into the drop tube from the ball release hole at a specified height. The test ball falls freely from the drop tube to the middle of the glass plate to be tested, and the tester checks whether the glass plate is broken by the falling ball and counts the glass fragments after breakage.
