Description

Technical Field

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

[0002] Tempered glass, also known as reinforced glass, is a type of safety glass that is made by heat-treating or chemically treating ordinary annealed glass to form a compressive stress layer on the glass surface and a tensile stress layer inside.

[0003] During the impact resistance test of tempered glass, although the clamping device can fix the glass plate, the open design of the test environment and the reserved entry point for the impact ball under protective conditions prevent the entire test system from being completely sealed.

[0004] While this semi-open structure meets the basic testing requirements, it introduces significant safety hazards. When tempered glass shatters upon impact, high-speed flying glass shards will scatter outwards from these open areas, creating dangerous splash zones. These shards not only pose a risk of injury to on-site personnel, but their irregular trajectories also increase the difficulty of protection. Furthermore, due to the wide and random distribution of the shards, subsequent cleanup becomes extremely tedious, requiring personnel to meticulously collect debris over a large area, which is both time-consuming and carries the risk of secondary injuries.

[0005] This situation is particularly prominent in laboratory environments where frequent testing is conducted, and the long-term accumulation of glass shards can also affect the accuracy and lifespan of testing equipment. Furthermore, if splattered fragments are not cleaned up promptly, they may interfere with subsequent tests and even lead to deviations in test data. Utility Model Content

[0006] The purpose of this invention is to provide a tempered glass impact resistance testing device. This device facilitates the clamping and restraint of tempered glass sheets, enabling impact resistance testing. It also prevents the tempered glass from shattering and flying debris, thus avoiding injury to workers. This invention solves the problem that in traditional impact resistance testing, tempered glass is typically clamped before an impact ball is launched. However, the clamped tempered glass is usually open, and even in some protected conditions, an inlet is provided to allow the impact ball to pass through, preventing complete sealing and still causing shattered glass fragments to fly, potentially injuring workers and making collection and cleaning of the fragments inconvenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tempered glass impact resistance testing device, comprising a transparent box 1, a bolt 1, a bolt 2, and a signal output line. A groove 1 is formed on the upper surface of the transparent box 1, and a bracket 1 is fixed to the inner wall of the groove 1. A tempered glass plate is placed inside the bracket 1. A bracket 2 is installed on the upper surface of the bracket 1. A transparent box 2 is installed on the upper surface of the transparent box 1. A groove 2 is formed on the lower surface of the transparent box 2. A rotating shaft is rotatably connected to the top of the inner wall of the groove 2. A rotating plate is fixed to the bottom of the rotating shaft. A disc is fixed to one side of the rotating plate. A pipe 1 is fixed to the upper surface of the transparent box 2. A pipe 2 is fixed to one side of the outer wall of the pipe 1. A plug ring is inserted into the pipe 2. A mounting plate is fixed to one side of the plug ring. A testing device is installed on one side of the mounting plate.

[0008] Preferably, a fixing plate is fixed to the front and rear ends of one side of the transparent box, and a fixing plate is fixed to the front and rear ends of the other side of the transparent box. A support column is fixed to the lower surface of the fixing plate. The fixing plate and the support column can support the transparent box, making the whole device stable and convenient for use.

[0009] Preferably, limit frames are fixed on both sides of the lower surface of the transparent box, and slots are provided at the front ends of the limit frames. A baffle is inserted into the slot, and a handle is fixed to the front end of the baffle. By inserting the baffle into the slot, the baffle can cover the bottom of the transparent box.

[0010] Preferably, the upper surface of the first bracket has a through groove two, and the bottom of the inner wall of the through groove two has a through groove three. Threaded holes three are respectively formed on both sides of the upper surface of the first bracket. A tempered glass plate is placed inside the through groove two. The upper surface of the second bracket has a through groove one, and threaded holes two are respectively formed on both sides of the upper surface of the second bracket. The bottom end of the first bolt passes through threaded holes two and three and is threaded. By having the bottom end of the first bolt pass through threaded holes two and three and is threaded, the second bracket can be constrained, and the tempered glass plate can be clamped and constrained, facilitating impact resistance testing of the tempered glass plate.

[0011] Preferably, a connecting plate is fixed to both the front and rear ends of the first transparent box, and a connecting plate is fixed to both sides of the first transparent box. A threaded hole is formed on the upper surface of the connecting plate. Similarly, a connecting plate is fixed to both the front and rear ends of the second transparent box, and a connecting plate is fixed to both sides of the second transparent box. A threaded hole is formed on the upper surface of the connecting plate. The bottom end of a bolt passes through both the threaded hole and the threaded hole, and is threadedly connected. By having the bottom end of the bolt pass through the threaded hole and the threaded hole, the first and second transparent boxes can be connected, and the second transparent box can be easily disassembled.

[0012] Preferably, a circular hole is formed on one side of the upper surface of the second transparent box. A motor is fixed to one side of the upper surface of the second transparent box, and the bottom end of the drive shaft of the motor extends into the circular hole. A rotating shaft is fixed to the bottom end of the drive shaft of the motor. The rotating shaft is fixed by the drive shaft of the motor, providing power for the rotation of the rotating shaft, the rotating plate, and the disc. This allows the circular hole to be covered or opened as needed. When the circular hole is open, it facilitates impact resistance testing. When the circular hole is covered, the first and second transparent boxes form a sealed space, preventing the tempered glass plate from breaking and scattering fragments during impact resistance testing.

[0013] Preferably, the upper surface of the second transparent box has a third circular hole, a first pipe is fixed to the upper surface of the second transparent box, a first pipe hole is opened on the upper surface of the first pipe, a second circular hole is opened on one side of the outer wall of the first pipe, a second pipe is fixed to one side of the outer wall of the first pipe, a second pipe hole is opened on one side of the second pipe, and an annular groove is opened on one side of the second pipe. The first pipe facilitates impact resistance testing of the tempered glass plate.

[0014] Preferably, the insertion ring is inserted into the annular groove, and a circular hole four is provided on the other side of the mounting plate. One side of the signal output line extends into the circular hole four and connects to the detection device. Handles two are fixed at the front and rear ends of the other side of the mounting plate, respectively. The detection device can detect the test object passing through the tube hole one. When the test object is detected, the detection device transmits a signal, causing the motor to start and the disc to rotate. The object passes through the circular hole three and enters the groove one to perform an impact resistance test on the tempered glass plate. After the object passes through the circular hole three, the motor starts again, causing the disc to block the circular hole three, thus preventing the tempered glass plate fragments from flying.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 The present invention provides two embodiments:

[0027] Example 1: A tempered glass impact resistance testing device includes a transparent box 12, bolt 13, bolt 24, and signal output line 41. A groove 8 is formed on the upper surface of the transparent box 12. A bracket 11 is fixed to the inner wall of the groove 18. A tempered glass plate 15 is placed inside the bracket 11. A bracket 22 is installed on the upper surface of the bracket 11. A transparent box 24 is installed on the upper surface of the transparent box 12. A groove 26 is formed on the lower surface of the transparent box 24. A rotating shaft 33 is rotatably connected to the top of the inner wall of the groove 26.

[0028] A fixing plate 3 is fixed to the front and rear ends of one side of the transparent box 2, and a fixing plate 3 is fixed to the front and rear ends of the other side of the transparent box 2. A support column 1 is fixed to the lower surface of the fixing plate 3.

[0029] A limit frame 20 is fixed on both sides of the lower surface of the transparent box 2. A slot 21 is opened at the front end of the limit frame 20, and a baffle 22 is inserted into the slot 21. A handle 23 is fixed at the front end of the baffle 22.

[0030] The upper surface of bracket 11 is provided with a through groove 2 18, and the bottom of the inner wall of through groove 2 18 is provided with a through groove 3 19. Threaded holes 3 17 are provided on both sides of the upper surface of bracket 11. A tempered glass plate 15 is placed in through groove 2 18. The upper surface of bracket 2 12 is provided with a through groove 14, and threaded holes 2 16 are provided on both sides of the upper surface of bracket 2 12. The bottom end of bolt 13 passes through threaded holes 2 16 and threaded holes 3 17 and is threadedly connected.

[0031] Bolt 13 has its bottom end passing through threaded hole 2 16 and threaded hole 3 17 and being threaded together, which allows the bracket 2 12 to be limited, making it easier to clamp and limit the tempered glass plate 15 and to conduct impact resistance tests on the tempered glass plate 15.

[0032] In this embodiment, when it is necessary to conduct an impact test on the tempered glass plate 15, the tempered glass plate 15 is placed in the through groove 2 18, and the bracket 2 12 is placed on the upper surface of the bracket 1 11. At the same time, the threaded hole 2 16 and the threaded hole 3 17 are vertically aligned. Then, the bottom end of the bolt 13 passes through the threaded hole 2 16 and the threaded hole 3 17 and is threaded together. This achieves the effect of facilitating the clamping and limiting of the tempered glass plate 15 and facilitating the impact test on the tempered glass plate 15.

[0033] Example 2:

[0034] A connecting plate 10 is fixed to the front and rear ends of a transparent box 2, and a connecting plate 10 is fixed to both sides of the transparent box 2. A threaded hole 9 is opened on the upper surface of the connecting plate 10. A connecting plate 25 is fixed to the front and rear ends of a transparent box 4, and a connecting plate 25 is fixed to both sides of the transparent box 4. A threaded hole 4 29 is opened on the upper surface of the connecting plate 25. The bottom end of the bolt 24 passes through the threaded hole 9 and the threaded hole 4 29 and is threadedly connected.

[0035] A circular hole 27 is provided on one side of the upper surface of the transparent box 24. A motor 5 is fixed on one side of the upper surface of the transparent box 24. The bottom end of the drive shaft of the motor 5 extends into the circular hole 27. A rotating shaft 33 is fixed on the bottom end of the drive shaft of the motor 5.

[0036] The motor 5 is equipped with a drive shaft fixed to the rotating shaft 33, which provides power for the rotation of the rotating shaft 33, the rotating plate 32 and the disc 31, so that the disc 31 can cover or open the circular hole 30 as needed.

[0037] Motor 5 is a servo motor. Structurally, a servo motor mainly consists of three parts: the stator, the rotor, and the position detector. The stator is similar to that of a regular AC motor, employing a laminated iron core structure with three-phase windings. It generates a rotating magnetic field by inputting three-phase AC power. The rotor varies depending on the type, with two common forms: permanent magnet rotors and squirrel-cage rotors. Permanent magnet rotors are mostly used in high-performance applications and are made of rare-earth permanent magnet materials with high magnetic energy product. A high-precision encoder or rotary transformer is usually installed at the tail of the motor as a position detector to provide real-time feedback of rotor position information.

[0038] Its working principle is essentially a closed-loop control system. When the controller issues a motion command, the drive circuit converts the control signal into three-phase alternating current to supply the stator windings, and the resulting rotating magnetic field drives the rotor to rotate. During this process, the encoder continuously monitors the actual position and speed of the rotor and feeds this information back to the controller. The controller compares the feedback signal with the command signal, calculates the error value, and then adjusts the output through control algorithms such as PID to ensure that the motor always follows the command requirements.

[0039] The upper surface of the transparent box 2 4 has a circular hole 30. The upper surface of the transparent box 2 4 is fixed with a pipe 1 6. The upper surface of the pipe 1 6 has a pipe hole 1 7. The outer wall of the pipe 1 6 has a circular hole 28. The outer wall of the pipe 1 6 is fixed with a pipe 2 34. The pipe 2 34 has a pipe hole 2 36 on one side. The pipe 2 34 has an annular groove 37 on one side.

[0040] The insertion ring 38 is inserted into the annular groove 37. A circular hole 42 is opened on the other side of the mounting plate 39. One side of the signal output line 41 extends into the circular hole 42 and is connected to the detection device 35. A handle 40 is fixed at the front and rear ends of the other side of the mounting plate 39.

[0041] The detection device 35 is used to detect the impact ball entering the tube hole 7, so as to control the motor 5 and simultaneously control the rotation of the disc 31.

[0042] The detection device 35 uses an infrared photoelectric sensor to detect the impact ball entering the tube hole 7. The infrared photoelectric sensor typically consists of an infrared emitting tube and a receiving tube. When the impact ball enters the tube hole 7 and passes through the detection area, it blocks the infrared light, causing a change in the signal at the receiving end, thereby triggering the control logic.

[0043] When the impact ball enters the first orifice 7 and blocks the infrared sensor, the sensor's output signal changes, and this signal is transmitted to the motor 5 controller. Upon receiving the signal, the controller immediately drives the motor 5, causing the disc 31 to rotate, opening the outlet of the first orifice 7 and allowing the impact ball to pass through. After the impact ball has completely passed through, the infrared sensor returns to its unobstructed state, and the output signal returns to its initial value. At this time, the controller restarts the motor 5, causing the disc 31 to rotate back to its original position and re-close the outlet of the first orifice 7. This achieves the goal of creating a sealed space between the transparent enclosure 2 and the transparent enclosure 4, preventing the broken tempered glass plate 15 from splashing and injuring personnel, while also making it inconvenient to collect and clean up the fragments.

[0044] In this embodiment, when it is necessary to conduct an impact resistance test on the tempered glass plate 15, an impact ball is launched into the tube hole 7. When the impact ball moves in the tube hole 7, the detection device 35 detects the impact ball, causing the motor 5 to start. The rotating shaft 33, rotating plate 32, and disc 31 can rotate as needed, so that the impact ball passes through the circular hole 30 and enters the groove 8 to conduct an impact resistance test on the tempered glass plate 15. After the impact ball enters the groove 26, the motor 5 starts again, causing the disc 31 to rotate and block the circular hole 30. This achieves the effect of facilitating the impact resistance test on the tempered glass plate 15, while preventing the tempered glass plate 15 from breaking and splashing after the impact test, thus preventing injury to the staff.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
