The invention discloses an anti-misoperation locking mechanism for a cab. The anti-misoperation locking mechanism comprises a lock body assembly and a bracket welding assembly matched with the lock body assembly. The lock body assembly comprises a mounting plate assembly, a hook assembly, a lock column assembly and a rocker arm assembly; the mounting plate assembly comprises two side mounting plates which are symmetrically arranged, a middle pin which is lined in the middle parts of the two side mounting plates, and a bottom pin shaft which is lined at the bottoms of the two side mounting plates; the rocker arm assembly is rotatably connected with the mounting plate assembly through a middle pin, and the lock column assembly is rotatably connected with the rocker arm assembly through a column plate pin shaft; the hook assembly comprises a hook shaft sleeve rotationally arranged on the bottom pin shaft in a sleeving mode, a hanging plate arranged on the hook shaft sleeve in a sleeving mode and a hook spring arranged on the hook shaft sleeve in a sleeving mode, and one end of the hook spring is connected to the hanging plate in a hanging mode. And a top groove of the hanging plate ismatched with a bottom pin of the rocker arm assembly to form an anti-misoperation locking mechanism. Normal locking is not affected, the lock body can be efficiently prevented from being mistakenly locked, and the safety of vehicle driving is greatly improved.
