Gate tilting-prevention locking device

The utility model discloses a gate tilting-prevention locking device, which comprises a locking beam and locking mechanisms, wherein the locking mechanism are symmetrically arranged at the two sides of a gate, and respectively consist of a support rod, a connecting pair A and a rotary pair B, each connecting pair A and the corresponding rotary pair B are respectively arranged at the two ends of the corresponding support rod, one end of each support rod is fixedly connected with the gate through the corresponding connecting pair A, the other end of each support rod is connected with the locking beam through the corresponding rotary pair A, the two ends of the locking beam are symmetrically provided with press plates, one end of each press plate is fixedly connected with the locking beam through a connecting pair B, and the other end of each press plate is provided with a rotary pair B. The gate tilting-prevention locking device has the advantages that the stable constraints along the horizontal and vertical directions are provided for the gate, the locking beam is effectively and fixedly arranged on the ground, the gate tilting danger is reduced, the better economic benefits and social benefits are realized, and the gate tilting-prevention locking device can be widely applied and popularized to the technical field of plane gate locking.
