Centrally-mounted handcart switch contact baffle locking device

The invention discloses a centrally-mounted handcart switch contact baffle locking device, relates to a locking device, and aims to solve the problem that an outer baffle of a static contact in a cabinet can automatically fall down after a 10kV centrally-mounted handcart switch of a transformer substation is pulled out of a switch cabin, so that an electrified static contact can be shielded, and an accidental electric shock accident of a human body can be effectively prevented. In order to solve the problems that a static contact baffle locking assembly is arranged on a centrally installed switchgear, a sliding baffle is arranged on two guide rods from top to bottom in a sliding mode, a first baffle driving connecting rod, a second baffle driving connecting rod and a torsion spring are installed on a fixed shaft in a rotating connection mode, and the fixed contact baffle locking assembly is arranged on the centrally installed switchgear. The two contact fixing blocks are installed at the front end of the slid
