Description

Technical Field

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

[0002] Tempered glass is a type of prestressed glass, meaning that compressive stress is formed on the glass surface through chemical or physical methods. When the glass is subjected to external force, the surface stress is first offset, and then the force is applied to the glass body. The load-bearing capacity, wind pressure resistance, and impact resistance of the glass are effectively improved. Due to the strength characteristics of tempered glass, it is often used in places with high safety protection requirements. In these places, if the strength quality of the tempered glass is substandard, it can easily cause serious consequences. Therefore, after the tempered glass is produced, samples are taken to conduct impact resistance tests.

[0003] When tempered glass is subjected to impact resistance tests, if the strength of the tempered glass is not suitable, it will break. The broken tempered glass needs to be cleaned up manually, which can easily injure workers. In addition, the tempered glass fragments from the impact test are large and will take up too much space in the collection frame. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a tempered glass production impact resistance testing device, including a test chamber 1 and an impact mechanism 2 set on the top of the test chamber 1. Support plates 3 are fixedly connected to both sides of the inner cavity of the test chamber 1. A protective frame 4 is fixedly connected to the lower front of the test chamber 1. A motor 6, a servo motor, is fixedly connected to one side of the inner cavity of the protective frame 4 and is electrically connected to an external power source. It is controlled by a control switch. The output shaft of the motor 6 is fixedly connected to a threaded rod 7 via a coupling. One end of the threaded rod 7 is rotatably connected to the other side of the inner cavity of the protective frame 4 via a bearing. A threaded sleeve 8 is threadedly connected to the surface of the threaded rod 7. A sliding door is provided at the upper front of the test chamber 1. The sliding port 9 has a sliding rod 10 slidably connected inside it. One end of the sliding rod 10 is fixedly connected to the threaded sleeve 8, and the other end of the sliding rod 10 is fixedly connected to the moving rod 11. One end of the moving rod 11 is fixedly connected to the push plate 12. The lower rear part of the inner cavity of the test chamber 1 is rotatably connected to the rotating rod 13 through the bearing. One end of the rotating rod 13 passes through the test chamber 1 and extends into the interior of the protective frame 4. The front part of the test chamber 1 has a rotating opening that matches the rotating rod 13. The surface of the rotating rod 13 and the interior of the test chamber 1 are fixedly connected to the crushing roller 14. The ends of the threaded rod 7 and the rotating rod 13 are both fixedly connected to the bevel gears 15, and the two bevel gears 15 mesh with each other.

[0021] It should be noted that a passage adapted to the crushing roller 14 is provided on the lower side of one side of the test chamber 1 to facilitate the discharge of broken tempered glass; the crushing roller 14 rotates inward (i.e., rotates in the direction of the motor 6), so that the crushing roller 14 impacts the push plate 12 in opposite directions, which can better impact and break the tempered glass.

[0022] Furthermore, in order to automatically open the movable door 16, the front of the test chamber 1 and above the sliding opening 9 is slidably connected to the movable door 16 through an opening, and a connecting rod 5 is fixedly connected to the sliding rod 10, with one end of the connecting rod 5 fixedly connected to the movable door 16.

[0023] Furthermore, to facilitate adjusting the steel ball to different heights for impact testing, the impact mechanism 2 includes an electric telescopic rod 21. The electric telescopic rod 21 is electrically connected to an external power source and controlled by a control switch. The top of the test chamber 1 is fixedly connected to the electric telescopic rod 21 through an opening. A sliding frame 22 is fixedly connected to the telescopic end of the electric telescopic rod 21. A limiting frame 24 is fixedly connected to the top of the test chamber 1 through an opening. The sliding frame 22 extends into the interior of the limiting frame 24. A sliding plate 23 is slidably connected inside the sliding frame 22. The steel ball for the impact test is placed on the sliding plate 23. The weight of the steel ball can be selected according to the specific circumstances of the impact test. A blocking plate 25 is fixedly connected to the top of the sliding frame 22.

[0024] In use, by controlling the extension of the electric telescopic rod 21, the sliding frame 22 is moved. The sliding frame 22 will move the sliding plate 23 upward, moving the steel ball on the sliding plate 23 to a suitable height. By pulling the sliding plate 23 outward, the sliding plate 23 will move out of the limiting frame 24, and the steel ball on the sliding plate 23 will fall downward into the test chamber 1 to conduct an impact test on the tempered glass on the two support plates 3.

[0025] By controlling the motor 6 to drive the threaded rod 7 to rotate, the threaded rod 7 will drive the threaded sleeve 8 to move. The threaded sleeve 8 will drive the moving rod 11 to move through the sliding rod 10. The moving rod 11 will drive the push plate 12 to move. If the steel ball impacts and breaks the tempered glass, the push plate 12 will push the broken tempered glass to the right. At the same time, the rotation of the threaded rod 7 will drive the left bevel gear 15 to rotate. The left bevel gear 15 will drive the rotating rod 13 to rotate through the right bevel gear 15. The rotating rod 13 will drive the crushing roller 14 to rotate. The crushing roller 14 will break the tempered glass that is about to be pushed out. The broken tempered glass will be discharged and collected from the discharge port.

[0026] As the sliding rod 10 moves, it will drive the sliding door 16 to move to the right through the connecting rod 5. The sliding door 16 will no longer block the placement opening. If the tempered glass is not broken, the tempered glass can be removed, the steel ball can be removed, and a new tempered glass can be placed for an impact test.
