Description

Technical Field

[0001] This utility model relates to the field of tempered glass drop ball testing technology, specifically a tempered glass drop ball testing device. Background Technology

[0002] The main purpose of the tempered glass drop ball test is to evaluate its strength and impact resistance. The test involves dropping a steel ball of a specified mass from a certain height to impact the tempered glass surface. The degree of damage to the glass is used to determine its impact resistance and whether its quality is up to standard.

[0003] For example, the Chinese authorized patent with publication number CN220708874U (Drop Ball Test Device for Glass Impact Resistance Testing) includes a glass fixing assembly, which comprises a housing structure, a moving structure, and a glass fixing structure. The moving structure is movably disposed within the housing structure, and the glass fixing structure is fixed to the moving structure. The test ball fixing assembly includes a support structure and a fixing structure, with the fixing structure having a test ball mounting portion. The technical solution of this application effectively solves the problem in the prior art where the drop ball test device needs to be changed according to the different sizes of the test glass during the drop ball test.

[0004] However, when performing ball drop tests on existing tempered glass, the landing point and height are unstable when the ball is dropped by hand, and the landing point is limited when using a ball-fixing structure, resulting in a small and incomplete testing range and inaccurate test results. Therefore, it does not meet the current requirements. To address this, we propose a ball drop test device for tempered glass. Utility Model Content

[0005] The purpose of this invention is to provide a ball-dropping test device for tempered glass, in order to solve the problems mentioned in the background art, where, when the ball is dropped by hand, the landing point and height are unstable, and when a ball-fixing structure is used for dropping, the landing point is limited, the test range is small and incomplete, resulting in inaccurate test results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tempered glass ball drop test device, comprising: a support leg, wherein multiple support legs are provided; side frames are welded to both sides of the support leg; a drop assembly is provided above the side frame; an adjustment column is provided at one end of the drop assembly; an adjustment hole is provided on one side surface of the adjustment column, wherein multiple adjustment holes are provided; a first support frame is welded to one side surface of the side frame; and an anti-slip pad is provided on the upper surface of the first support frame.

[0007] Preferably, the falling assembly includes a second support frame and a falling ball part. The upper surface of the second support frame is provided with a vertically penetrating moving groove, and the falling ball part moves along the moving groove. One end of the moving groove is provided with an installation opening, and a fixing plate is provided inside the installation opening. The corner of the fixing plate is fixed to the second support frame by an external screw.

[0008] Preferably, the other end of the second support frame is provided with a rotating sleeve, the rotating sleeve is provided with an adjusting seat inside, and the rotating sleeve is rotatably connected to the adjusting seat through an external bearing.

[0009] Preferably, the center of the adjusting seat is provided with a slot, and the adjusting seat moves up and down along the adjusting column through the slot. A knob hole is provided on one side of the inner wall of the slot, and the knob hole passes through the adjusting seat. A fixing knob is threaded to one end of the knob hole.

[0010] Preferably, the ball-dropping part includes a ball-dropping sleeve and a limiting seat, with the limiting seat located on both sides of the ball-dropping sleeve. The ball-dropping sleeve has a ball-dropping groove that runs vertically through it. The inner walls of both sides of the moving groove are provided with limiting grooves, and the limiting seat moves along the limiting grooves.

[0011] Preferably, the lower surface of the limiting seat is provided with a roller groove, and a roller is provided inside the roller groove, and the roller is rotatably connected to the roller groove through a wheel axle.

[0012] Preferably, mounting plates are welded to both sides of the bottom end of the adjusting column, and the external bolts of the mounting plates are threadedly connected to the side frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets a falling component at one end of the adjusting column. The falling component mainly consists of a falling ball part, a first support frame, an adjusting seat and a rotating sleeve. The adjusting seat is fitted onto the outside of the adjusting column through a slot and moves up and down along the adjusting column to adjust the height. It is fixed by a fixing knob. The tempered glass to be tested is placed on the side frame and the first support frame. The second support frame is rotated to adjust its position. After adjusting the position, the falling ball part is moved so that the falling ball groove is directly above the test position. The steel ball is placed into the falling ball groove and falls from the falling ball groove onto the tempered glass to perform the falling ball test on the tempered glass. Through the bidirectional adjustment of the second support frame and the falling ball part, the test range is improved. This solves the problem that when the existing tempered glass is tested by falling ball, the landing point and height are unstable when the ball is dropped by hand. When the ball is dropped using a ball fixing structure, the landing point position is limited, the test range is small and incomplete, and the test results are inaccurate.

[0015] (2) By setting limiting grooves on both sides of the inner wall of the moving groove, the ball drop part is inserted along the installation opening, the ball drop sleeve moves along the moving groove, and the limiting seat moves along the limiting groove. When the limiting seat moves, the roller rotates due to friction, which improves the smoothness of the ball drop part movement. Then, the installation opening is blocked and protected by the fixing plate to prevent the ball drop part from slipping. At the same time, the ball drop part can be separated from the second support frame for replacement, which improves the flexibility of replacement. Attached Figure Description

A knob hole 17 is provided on one side of the inner wall of the slot 15. The knob hole 17 passes through the adjusting seat 14. One end of the knob hole 17 is threadedly connected to a fixing knob 16. The adjusting seat 14 is sleeved on the outside of the adjusting column 5 through the slot 15 and moves up and down along the adjusting column 5 to adjust the height. After adjusting the height according to the requirements of the tempered glass drop ball test, one end of the fixing knob 16 passes through the knob hole 17 and the adjusting hole 6 and is threadedly connected to the knob hole 17 to fix the adjusting seat 14 to the adjusting column 5.

[0023] The ball drop section 11 includes a ball drop sleeve 19 and a limiting seat 20. The limiting seat 20 is located on both sides of the ball drop sleeve 19. The ball drop section 11 is inserted along the installation opening 12. The ball drop sleeve 19 moves along the moving groove 9, and the limiting seat 20 moves along the limiting groove 10.
