The structure of the toilet lid damper to keep the pressure constant

Abstract

The invention discloses a structure for a toilet seat damper to maintain constant pressure, which includes a cover, a sealing ring, a valve core, a rotating ring, an oil chamber shell, and a blade; the cover is set in the oil chamber shell and the cover is The outer wall is welded to the inner wall of the oil chamber shell. The sealing ring is sleeved in the rubber ring groove of the valve core and is located between the cover and the valve core. The middle hole of the cover is sleeved on the upper end of the valve core. The cylindrical boss at the lower end of the valve core It is placed in the cylindrical groove on the inner bottom of the oil chamber shell. Since the present invention adds a rotating ring, the triangular groove on the rotating ring cooperates with the triangular convex hull in the middle of the valve core. Under the action of oil pressure, the rotating ring will climb up or down along the slope of the triangular convex hull, ensuring that the valve core The gap between the lower surface of the annular convex ring and the side of the blade is always 0mm. When the damping effect is ensured, the damping oil can only pass through the small oil groove, ensuring that the size of the oil passing area remains unchanged, thereby ensuring the stability of the toilet cover's slow-down time. .

Description

technical field [0001] The invention relates to a toilet lid, in particular to a structure for a toilet lid damper to keep pressure constant. Background technique [0002] Most toilet lid damping mechanisms realize the damping function simply by damping oil pressure. This type of structural damper mainly pushes the vane through damping oil pressure to realize the closing and opening of the oil chamber. At present, in order to reduce costs, simplify the production process, and achieve automatic production, the toilet lid damping mechanism has gradually been upgraded from bolted to welded. The welding of the mechanism can reduce the number of parts and affect the performance of the mechanism. The problem is that : Because the damping oil in the oil chamber will produce an outward pressure on the valve core, when the mechanism is due to welding accuracy problems, the valve core is directly affected by the oil pressure, so that there will be gaps in the lateral fit between the b...

Problems solved by technology

At present, in order to reduce costs, simplify the production process, and achieve automatic production, the toilet lid damping mechanism has gradually been upgraded from bolted to welded. The welding of the mechanism can reduce the number of parts and affect the performance of the mechanism. The problem is that : Because the damping oil in the oil chamber will produce an outward pressure on the valve core, when the mechanism is due to welding accuracy problems, the valve core is directly affected by the oil pressure, so that there will be gaps in the lateral fit between the blade and the valve core. During the process, the damping oil will pass through the gap and the small oil groove at the same time, but cannot only pass through the designated small oil groove, which will lead to poor batch stability, and the slow falling time of the toilet cover will fluctuate, which cannot meet the requirements of the industry standard
