Test device

Abstract

The application provides a testing device, and relates to the field of detection devices; the testing device comprises a pulling assembly, a counterweight assembly, a detection assembly and a transfer clamp; the transfer clamp is used for transferring a syringe; the pulling assembly comprises a pulling clamp jaw; the pulling clamp jaw and the transfer clamp are arranged at intervals; the pulling clamp jaw is used for clamping a needle tube; the counterweight assembly comprises a carrier, a connecting piece, a counterweight and a lifting platform; the carrier and the counterweight are connected to the connecting piece; the carrier is provided with a supporting groove; and the two side walls of the supporting groove are provided with limiting protrusions; the counterweight assembly can be translated relative to the transfer clamp, so that the bottom flange part of the syringe is located between the limiting protrusions and the bottom wall of the supporting groove; the lifting platform is used for lifting the counterweight; and the detection assembly is used for detecting the position change of the connecting piece in the test. The testing device provided by the application solves the technical problems that fingers are easily damaged in the finger clamp test of the clamped and conveyed syringe, the moving mechanism is easily damaged, and constant pulling force detection cannot be realized in the prior art.
