A slow-down device for a toilet cover

Abstract

The invention discloses a closestool cover plate descent control device which comprises a rotating shaft, a blade and a shaft sleeve. A radial end face is formed at one end of the rotating shaft and provided with an oil groove, an oil inlet of the oil groove is large, the tail end of the oil groove is small, and a rib is convexly arranged on the rotating shaft in the axial direction. A shaft cavity is formed in the blade in the axial direction, an insertion groove is integrally convexly formed in the side wall of the shaft cavity, the shaft cavity of the blade is in sleeved connection with the rotating shaft, the rib of the rotating shaft is inserted in the insertion groove of the blade, and a plurality of oil grooves are formed in the side walls of the two sides of the insertion grooves at intervals. The shaft sleeve is in sleeved connection with the rotating shaft, and a sealed cavity is formed between the shaft sleeve and the rotating shaft and filled with damping oil. When the shaft sleeve rotates, the damping oil drives the blade to rotate relative to the rotating shaft, the rib of the rotating shaft seals the oil holes, and the damping oil flows towards the oil grooves; when the shaft sleeve rotates in the opposite direction, the damping oil drives the blade to rotate n the reverse direction relative to the rotating shaft, the rib of the rotating shaft opens the oil holes, and the damping oil passes the oil holes. The closestool cover plate descent control device has reliability in opening and closing and is simple to assemble and simple in manufacturing process.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a slow lowering device for a toilet cover. Background technique [0002] During the use of the toilet, the cover plate is turned up or down frequently, and the toilet cover and the toilet body are usually connected by rotation of a mechanical shaft. When putting down the toilet cover, due to the effect of the gravity of the toilet cover itself, it falls freely, and the toilet cover collides with the toilet body, which makes the toilet cover easy to break and shortens the service life. [0003] In order to slow down the falling speed of the toilet cover, a slow-down device is usually applied on the toilet cover. Rib, the blade installed on the protruding rib; the blade is installed on the protruding rib to form a one-way rotation, the sleeve rotates in one direction, the blade rotates away from the oil hole, and when the sleeve rotates in the opposite direction, the blade t...

AI Technical Summary

Problems solved by technology

[0004] The oil passage hole of the toilet cover slow down device is small, so that the oil passage is small, and the resistance is relatively large when the toilet cover is turned up; at the same time, the blade is divided into a leaf bar and a leaf surface; The installation groove, the shaft hole of the blade shaft for the insertion of the blade rod is opened on the installation groove body, and the shaft hole goes deep into the inside of the protruding rib. The manufacturing process of the blade structure is relatively complicated, and the assembly is relatively complicated
