Description

Technical Field

[0001] The utility model relates to the field of mechanical connection performance testing, in particular to a mechanical connection performance testing device for a mechanical connector. Background Art

[0002] Building mechanical connectors refer to structures installed on buildings by mechanical connection, such as door frames, window frames, and guardrails. These connectors are installed on buildings by mechanical connection after the construction is completed. In order to improve the safety characteristics of buildings, it is usually necessary to test the mechanical connection performance of building mechanical connectors, that is, to test whether the connectors have reasonable connection strength on the building through mechanical connection.

[0003] After searching the patent document with the publication number CN218725256U, the patent document discloses "a mechanical connection performance test device for building mechanical connectors, which first contacts the connector to be tested through the contact head, and then starts the motor, which drives the rotating disk to rotate through the output shaft. The rotating disk drives the eccentric shaft to rotate during the rotation process, and the eccentric shaft then drives the inner cylinder to rotate together. At this time, the elastic member installed on the inner cylinder contacts the slide seat. The rotating disk drives the eccentric shaft to make eccentric movement, so the distance between the eccentric shaft and the hole body is variable. At this time, the slide seat can be driven to slide through the elastic member, and then the slide seat drives the contact head to apply a force to the connector to be tested. The reset elasticity can drive the contact head to move in the opposite direction, so that the contact head can automatically restore to the state when it is not under force";

[0004] When the above device is in use, the installation position of the window frame will be determined according to the design requirements of the building, so that the height of the window frames in each building is different. Although the above device has a raised frame, the height of the raised frame is fixed, so that the device can only perform test operations on window frames of appropriate heights, resulting in poor applicability of the device.
