The invention discloses a sealing compensation vibration buffering type elevator buffer, and relates to the technical field of elevators. The hydraulic cylinder comprises a cylinder body, an outer cylinder body and a plunger, the outer cylinder body is fixed to the top of the cylinder body, the plunger penetrates through and is slidably installed at the top of the outer cylinder body, a sealing buffer device is arranged outside the cylinder body, and the sealing buffer device comprises a U-shaped fixed lantern ring, a U-shaped sliding lantern ring, a pressing ring, a rubber block and a rubber ring. The U-shaped fixing lantern ring is fixed to the top of the cylinder body. Through the arrangement of the sealing buffer device, under the action of the elastic force of a spring of a U-shaped sliding lantern ring, the U-shaped sliding lantern ring conducts secondary buffering on the impact force borne by the buffer, meanwhile, a rubber block, the U-shaped sliding lantern ring and an outer barrel are matched to drive an inclined face of a pressing ring to extrude the rubber block, and therefore when the buffer is impacted, the rubber block is prevented from falling off. And the rubber block seals a gap between the outer cylinder and the plunger, so that the problem that hydraulic oil in the outer cylinder is easy to leak is avoided.
本发明公开了一种密封补偿缓振式电梯缓冲器,涉及电梯技术领域。本发明包括缸体、外筒体和柱塞,所述外筒体固定在缸体的顶部,所述柱塞贯穿且滑动安装在外筒体的顶部,所述缸体的外部设置有密封缓冲装置,所述密封缓冲装置包括U形固定套环、U形滑动套环、压环、橡胶块和橡胶环,所述U形固定套环固定在缸体的顶部。本发明通过密封缓冲装置的设置,在U形滑动套环的弹簧弹力作用下,使得U形滑动套环对缓冲器受到的冲击力二级缓冲,同时橡胶块、U形滑动套环和外筒体配合带动压环的斜面对橡胶块进行挤压,从而使得缓冲器在受到冲击时,橡胶块对外筒体和柱塞之间的缝隙进行密封,从而避免了外筒体内的液压油容易发生泄漏的问题。
