Description

Technical Field

[0001] The utility model relates to the technical field of elevator full load control, in particular to an elevator weighing switch installation structure. Background Art

[0002] When the elevator is fully loaded or overweight, the elevator will sound an alarm or suspend operation. During the assembly and installation of the elevator, whether the weighing switch is installed in the right position affects the accuracy of the full load and overweight detection. In addition, during the elevator operation test, the rapid descent and emergency stop of the elevator will be simulated. The current full load and overweight switch is easily damaged by the inertial impact of the car during the emergency stop.

[0018] The utility model designs an elevator weighing switch installation structure. The weighing switch assembly comprises a first bending plate, a second bending plate, a buffer spring, a guide rod and a micro switch installed on the second bending plate. The buffer spring is located between the first bending plate and the second bending plate.
