Outward opening door lock for elevator

Abstract

The invention provides an outward opening door lock for an elevator, and belongs to the technical field of the elevator. The outward opening door lock for the elevator comprises a bottom shell, a lock bolt, a lock rod arranged in the bottom shell, a moving point connecting piece, a quiescent point seat, a backward spinning piece, a rotating sleeve, a lifting piece, a driver and a detecting switch. The moving point connecting piece and the backward spinning piece are sleeved on the lock rod respectively, the two ends of the lock rod stretch out from the wall of the bottom shell to be connected with an unlocking piece and the lock bolt respectively, the moving point connecting piece is close to the outward opening lock piece end, a first elastic piece is arranged between the moving point connecting piece and the wall of the bottom shell, a moving point is arranged at one end of the moving point connecting piece, the detecting switch is fixed on the bottom shell, one end of the lifting piece is connected with the driver, and the other end of the lifting piece is matched with the backward spinning piece for moving. In a locking state, the moving point is connected with a quiescent point in a matched mode, wherein the quiescent point is fixed on the quiescent point seat, and the lifting piece makes contact with the detecting switch, and in an unlocking state, one end of the rotating sleeve makes contact with the backward spinning piece, and the power line of the detecting switch, the power line of the driver and the power line of the quiescent point seat are connected with an outer control cabinet. The structure which is linked by components and a two-way electromagnet are used for driving the outward opening door lock, therefore, unlocking and locking are achieved, the unlocking state and the locking state can be detected through the detecting switch, and the outward opening door lock for the elevator is simple in structure, convenient to assemble and low in cost.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to an outer door lock for elevators. Background technique [0002] In the existing elevator, when the door lock is locked, the door handle is not allowed to be pressed down, the door lock is easily damaged, it is not easy to assemble, the processing is difficult to complete, and the assembly is inconvenient. In the locked state, the accuracy is poor. Contents of the invention [0003] In view of the above-mentioned existing technical problems, the present invention provides an outer door lock for an elevator. By changing the overall structure, the door handle cannot be pressed down to damage the door lock. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The invention includes a bottom case, a lock tongue and a locking rod placed in the bottom case, a moving point connector, a static point seat, a lower screw, a rot...
