Rotary buffer

Abstract

The invention discloses a rotary buffer, comprising a cylinder body and a shaft core, wherein the inner wall of the cylinder body is provided with protruding separation plates; one end of the shaft core is arranged in an inner cavity of the cylinder body and forms a seal cavity with the cylinder body, and the other end thereof extends out of the cylinder body; the shaft core is also provided withvanes; blades are arranged between the vanes and the cylinder body; the vanes, the blades and the separation plates partition the inner cavity of the cylinder body into non-compressed cavities and compressed cavities; damping oil is respectively filled in the non-compressed cavities and the compressed cavities; the vane is provided with a plurality of oil discharge gaps; a fixture block is arranged between the oil discharge gaps; the blade comprises an arc-shaped mainboard and an oil seal rib plate arranged at one side of the arc-shaped mainboard; a plurality of sliding holes for the fixture block to sequentially insert are arranged on the arc-shaped mainboard; and the sliding hole is larger than the fixture block so as to lead the fixture block to slide in the sliding hole. The inventionaims at providing a rotary buffer which has good buffering effect, difficult dropping of the blades, good product quality and simple structure.

Description

[technical field] [0001] The present invention relates to a rotary damper, in particular to a rotary damper which is used on a toilet cover and a seat ring and prolongs the falling time thereof. [Background technique] [0002] At present, the cover plate and the seat ring of the toilet are generally directly connected by a pin shaft, or a spring is used for buffering, and a pin shaft structure is used to make a loud knocking sound when the cover plate and seat ring are opened and put down, while the spring is used to , easy to corrode and rust and damage. [0003] In order to solve the above problems, some manufacturers adopt damping oil buffers, which generally include a cylinder body and a shaft core, and connect the cover plate of the toilet with the shaft core. The applicant submitted a patent application on March 25, 2002, the patent number is ZL02226427.2, and the name is "An Adjustable Buffer", and the authorization announcement date is February 26, 2003. In this pa...

Problems solved by technology

In this patent, the blades and the shaft core are separated, so that the blades are easy to fall off the shaft core during long-term use; in addition, there are tooth-shaped openings for unloading oil on the ribs at the end of the blades, and the ribs The plate is very thin, so the rib plate with toothed mouth is easy to be damaged after long-term use, so that the blade loses the function of cutting or conducting the oil passage, and the product quality is stable
