Abstract

The invention discloses a damp-proof buffer for lifts. The damp-proof buffer comprises mufflers, a shaft lever, a pressure-accumulated sponge, a oil draining pipe, a straight bar, an oil bin, a protective jacket and a mount; the mufflers cover bump heads, the lower ends of the bump heads are connected with a supporting plate, the upper end of the shaft lever is fixedly connected with the supporting plate, the lower end of the shaft lever penetrates the top of a shell to be connected with a spring, the oil bin is arranged in the lower side of the shell and provided with an oil outlet at the lower side, the oil outlet is communicated with the oil draining pipe, the protective jacket covers the shell, the lower side of the protective sleeve is connected with a bearing seat, and the mount is fixedly connected to the lower side of the bearing seat. The damp-proof buffer for lifts can improve buffering capacity greatly; with a dustproof and spring protective structure, application safety ofthe buffer is improved and service life thereof is prolonged greatly.

Description

technical field [0001] The invention relates to the field of buffers, in particular to a buffer for elevators with a moisture-proof effect. Background technique [0002] The elevator buffer is an important safety component of the elevator. It is installed at the lower part of the elevator shaft. When the elevator is in an emergency, it can be used to reduce the impact of the elevator falling and minimize the injury of the people in the elevator. [0003] The current elevator buffers basically rely on a single strong spring with a telescopic rod to achieve buffering, so there are certain defects in the buffering capacity. In addition, since the elevator buffers are basically installed in the pit of the elevator shaft, good At the same time, the spring as an important part also needs to be protected. However, the elevator buffers on the market basically do not have these. Therefore, a kind of elevator with better buffering effect, moisture-proof and spring protection functions...
