Description

Technical Field

[0001] The utility model relates to the technical field of door and window detection, in particular to a detection device for the sealing and compression resistance performance of doors and windows. Background Art

[0002] Testing the sealing and compression resistance of doors and windows is an important part of ensuring the quality and use of doors and windows. During the production, installation and use of doors and windows, sealing and compression resistance are two key indicators for evaluating their quality. In order to accurately evaluate these properties, special testing equipment is required. Sealing tests are usually conducted to determine the sealing effect of doors and windows in the closed state to prevent the penetration of air, water or other external substances. Compression resistance tests evaluate the performance of doors and windows when subjected to external pressure, including wind pressure resistance, impact resistance and other capabilities.

[0003] After searching, the utility model patent with Chinese patent announcement number CN219736687U discloses a door and window watertight and airtight performance testing device, including a mounting plate, the upper end of the mounting plate is fixedly connected to a water tank, the upper end of the water tank is fixedly connected to a testing box, one side of the testing box is fixedly connected to a fixing plate, the surface of the fixing plate is provided with an opening, one side of the fixing plate is fixedly connected to a first electric push rod, the lower end of the first electric push rod is fixedly connected to an upper clamping block, one side of the fixing plate is symmetrically provided with a second electric push rod, one side of the second electric push rod is fixedly connected to a side clamping block, and one side of the fixing plate is fixedly connected to a lower clamping block.
