Description
Technical Field
[0001] This utility model relates to the technical field of door and window inspection, specifically a door and window structural strength testing platform. Background Technology
[0002] Modern doors and windows consist of three parts: the window frame, the glass, and the moving parts (hinges, handles, pulleys, etc.). They can generally be divided into casement windows, sliding windows, and louvered windows. With the development of building technology and the improvement of people's living standards, the structure of doors and windows has become increasingly complex. Therefore, in order to ensure that doors and windows meet design requirements, it is usually necessary to conduct quality inspections on the window frame and moving parts.
[0003] Existing door and window structural strength testing platforms mostly consist of a combination of a fixing structure and a pressure-applying structure. The fixing structure secures the door and window, while the pressure-applying structure applies pressure to the door and window. The critical point of pressure damage is then detected based on the applied pressure, thereby determining whether the structural strength of the door and window is up to standard. However, the pressure applied by hydraulics and machines can easily cause damage to doors and windows due to excessive and continuous pressure. In daily use, doors and windows are often damaged by impacts or collisions, and conventional pressure-applying structures are difficult to simulate the impact damage that doors and windows suffer during daily use. Therefore, those skilled in the art have proposed a door and window structural strength testing platform to solve the problems mentioned in the background. Utility Model Content

The third telescopic component 30 and the fourth telescopic component 31 are installed and fixed by a mounting sleeve.
[0024] Working principle: In use, the first driving component 6 drives the bidirectional threaded rod 4 to rotate, which in turn drives the first slider 5 to move, and then drives the clamping frame 9 to move, so that the two ends of the door and window are respectively placed on the fixed clamping plate 10 and the movable clamping plate 12 on the two clamping frames 9. The end of the door and window is placed on the fixed clamping plate 10, and the first telescopic component 11 drives the movable clamping plate 12 to move down to cooperate with the fixed clamping plate 10 to clamp the end of the door and window. First, adjust the horizontal Y-axis position of the take-up and release box 24. The second driving component 17 drives the first one-way threaded rod 16 to rotate, which in turn drives the second slider 14 to move, which in turn drives the second telescopic component 15 and the top plate 2 to move. Then, adjust the horizontal X-axis position of the take-up and release box 24. The third driving component 21 drives the second one-way threaded rod 20 to rotate, which in turn adjusts the horizontal position of the third slider 22. The second telescopic component 15 adjusts the take-up and release. The vertical position of box 24 places the impactor 27 directly above the detection point of the door and window. The fourth telescopic member 31 is moved down by the third telescopic member 30, so that the lifting rod 32 is placed below the lower roller 28. The lifting rod 32 passes through the second movable groove 33 and is inserted below the two lower rollers 28 by the fourth telescopic member 31. Then, the lifting rod 32 is moved up by the third telescopic member 30, and the lifting rod 32 lifts the suspension rope 26. The impactor 27 is lifted to a certain height. Then, the fourth telescopic member 31 drives the lifting rod 32 to retract quickly. The suspension rope 26 moves down without the action of the lifting rod 32, and the impactor 27 falls down onto the door and window. The gravitational potential energy of the impactor 27 is calculated by the weight of the impactor 27 and the height difference between it and the door and window, so as to determine the magnitude of the impact force. By changing the weight and height of the impactor 27, comparative impact tests are conducted on different parts of the door and window to test whether the structural strength of the door and window is qualified.
