This utility model discloses a resistive touchscreen pressure testing device, relating to the field of touchscreen technology. It includes a base with a sliding groove; a sliding block located within the sliding groove, a support seat fixed to the sliding block, a support block fixed to the bottom of the support seat, a positioning block fixed to the base, and an electric telescopic rod mounted on the positioning block, the distal end of which is fixed to the support block; and a testing component. This utility model, through its designed testing component, ensures that when the control motor starts, the output shaft of the control motor drives the rocker arm to rotate, causing the rotating rod to move with the rocker arm's rotation, thereby driving the guide post to perform linear reciprocating motion within the sliding hole. Unlike traditional pressure testing devices, this ensures that during the pressure testing process, regardless of the applied pressure or precise pressure adjustment, it can be monitored in real time by the pressure sensor, truly achieving accurate pressure testing of the resistive touchscreen and greatly improving the pressure testing effect.

The utility model discloses an elastic member suspension tension and compression testing device, which relates to the technical field of tension and compression testing devices and comprises a base, a fixed seat is fixedly connected to the left side of the top of the base, a central controller is fixedly connected to the rear side wall of the fixed seat, and fixed frames are fixedly connected to the tops of the fixed seat and a movable sliding seat. Pressure compensation clamping assemblies are arranged in the two fixing frames, and a testing assembly is arranged on the right side of the top of the base. According to the utility model, through the arranged pressure compensation clamping assembly, pressure adjustment can be carried out according to a pressure signal fed back by a pressure sensor, and the clamping force of the elastic member suspension is ensured to be within a proper range, so that the reliability of test data is improved; the device can accurately control and adjust the magnitude of the applied tension or pressure to meet different test requirements, so that the performance of the elastic part suspension under different tension and pressure conditions is accurately evaluated.
