The invention provides terminal static mechanical load test equipment for a 12kV isolating switch, which comprises a mobile platform, a worm-gear lifting mechanism and a stress test unit, wherein themobile platform is used for fixing the worm-gear lifting mechanism, the stress test unit and an isolating switch test sample; the worm-gear lifting mechanism includes a first worm-gear lifting unit, asecond worm-gear lifting unit and a third worm-gear lifting unit which respectively move along a straight line and are connected with a terminal of the isolating switch test sample through the stresstest unit; and the stress test unit is used for obtaining a load value of the terminal. The terminal static mechanical load test equipment realizes flexible loading of six kinds of loads in three different directions for various types of 12kV isolating switch terminals through setting the worm-gear lifting units moving towards different directions on the mobile platform. In addition, the equipment is small in size, easy to operate and high in precision, and can greatly improve the test efficiency and save the labor cost when conducting 12kV isolating switch tests and spot check tests.
