Description

Technical Field

[0001] The utility model relates to the technical field of elevator buffer equipment, in particular to an elevator safety buffer device. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. An elevator pit buffer is a device installed at the bottom of the elevator shaft that can reduce the impact force when the elevator is in a state of motion or stalls, protecting the elevator itself and personnel. During the installation of the elevator, in accordance with national standards and regulations, buffers must be used to ensure the safety of elevator passengers.

[0003] In this regard, the Chinese utility model patent with the authorization announcement number CN205328406U discloses an adjustment rod for an elevator buffer and an elevator buffer. The elevator buffer adjustment rod is used to penetrate the throttle nozzle of the plunger barrel of the elevator buffer, and the elevator buffer adjustment rod includes a gap forming part, and a gap for liquid to pass through is formed between the gap forming part and the throttle nozzle. Starting from the free end of the gap forming part to the fixed end of the gap forming part, the cross-sectional area of ​​the gap forming part changes in the length direction of the elevator buffer adjustment rod. In at least one longitudinal section that passes through the geometric center of the end face of the free end and is intercepted along the length direction of the elevator buffer adjustment rod, the side edge of the longitudinal section is not a single straight line shape. In this way, the utility model provides an elevator buffer adjustment rod that can more reasonably change the damping of the elevator buffer, thereby providing an elevator buffer that reasonably decelerates the elevator car or counterweight and improves the ride comfort of the elevator.

[0004] In rainy and snowy weather, water seepage may occur in the elevator shaft.
