AI Technical Summary
Technical Problem
The clamping structure of traditional prestressed steel structure testing equipment is prone to loosening due to loose bolts or external vibration, resulting in insecure clamping.
Method used
The drive motor drives the rotating plate to swing the pull rod synchronously. The connecting rod pushes the slider to move linearly along the slide rail. The spring pushes the clamping plate to form an elastic clamping surface, which adaptively adjusts the clamping force. Combined with the high-precision sliding pair of the T-shaped slide rail and the slider, the clamping stability is ensured.
Benefits of technology
It effectively avoids clamping failure caused by loosening of traditional screw clamps, and achieves high-precision and stable prestress detection of steel structures.

Abstract
This utility model relates to the technical field of prestressed steel structure testing equipment, and solves the problem that after using a simple screw structure to rotate downwards and complete the compression and fixing operation of the steel structure, the clamping may become unstable due to loose bolts or external vibration. Specifically, it is a prestressed steel structure testing equipment, including an operating table. A testing structure is fixedly connected to the top surface of the operating table, and a clamping structure is fixedly connected to the surface of the operating table in an axisymmetric manner. The side of the clamping structure is provided with a fitting structure. The clamping structure includes a slide rail fixedly connected to the top surface of the operating table, a drive motor fixedly connected to the back of the slide rail, the output end of the drive motor passing through the slide rail and a rotating plate fixedly connected to one end, and pull rods rotatably connected to both ends of the rotating plate. A connecting rod is rotatably connected to one end of the pull rod, and a slider is fixedly connected to the top of the connecting rod. The slider is slidably connected to the surface of the slide rail.
