Rotary buffer

Abstract

The invention discloses a rotary buffer, comprising a cylinder body and an axle core, wherein raised shims are arranged on the inner wall of the cylinder body; a seal cavity is formed between one end of the axle core and the cylinder body after the end of the axle core is arranged in the inner cavity of the cylinder body; the other end of the axle core extends out of the cylinder body; fins with outer walls being tangent to the inner wall of the cylinder body are arranged on the axle core; vanes are arranged between the axle core and the shims; the shims, the vanes and the fins separate the inner cavity of the cylinder body into non-compressed cavities and compressed cavities; damping oil is filled in the non-compressed cavities and the compressed cavities; each vane comprises an arc-shaped main plate and an oil sealing rib plate and an oil unloading rib plate; the oil sealing rib plate and the oil unloading rib plate are respectively arranged in front of and at the back of the arc-shaped main plate; the back of the arc-shaped main plate pushes against the axle core; movement space which is used for the shims to insert and is thicker than the shims is formed between the oil sealing rib plate and the oil unloading rib plate; and a plurality of oil unloading nicks are arranged on the oil unloading rib plate and the arc-shaped main plate. The rotary buffer has good buffering effect, durable vanes, good quality, small machining tolerance and simple structure and is convenient to machine.

Description

[technical field] [0001] The present invention relates to a swivel damper, in particular to a swivel damper used on a toilet cover and a seat to prolong its falling time. [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 patent, there are toothed ...

AI Technical Summary

Problems solved by technology

In this patent, there are toothed openings for unloading oil on the ribs at the end of the blades. The ribs are very thin, so the ribs with toothed openings are easily damaged after long-term use, making the blades lose cutting or conduction The role of the oil channel ensures stable product quality; moreover, there is a step on the separator of the shaft core. When the step is stuck to the inside of the blade, an oil guide channel is formed between the separator and the blade. It is related to the size of the toothed mouth. In this way, the size error of any one of the steps and the toothed mouth will affect the size of the oil guide channel during processing, so the processing error is large and the processing is inconvenient.
