Description
Technical field
The utility model relates to a kind of Slow-falling device, particularly a kind of Slow-falling device that is used for lavatory lid.
Background technology
Traditional cover plate does not have Slow-falling device mostly, causes under external force, and cover plate falls suddenly, sends the huge sound even damages cover plate.Existing cover plate Slow-falling device complex structure and suitability are poor, as the disclosed turning gear that falls slowly of Japan Patent 4-282039, one movement of valve need be set, complex structure not only, and in the time need adjusting whereabouts torsion according to the difference of cover plate weight, must change movement of valve or change the damping oil of different viscosities, this more change jobs very loaded down with trivial details.
The utility model content
The utility model proposes compact conformation, and has good fit a kind of Slow-falling device at above problem.
Slow-falling device of the present utility model comprises axle sleeve, rotating shaft and rotating shaft fixture; Be provided with oil groove in the axle sleeve and isolated rib; Rotating shaft plugs together in axle sleeve and with the rib coupling axle sleeve internal cavity is divided into two; It is characterized in that: rotating shaft is provided with two blades that have oil-through hole of symmetry, and its length is identical with the isolation rib; Blade is provided with oil-through hole baffle plate and baffle plate fixture; The oil-through hole baffle plate can be done moving among a small circle in the gap of baffle plate fixture and blade.
Be ease of assembly, the utility model is crossed the oil groove place in the axle sleeve chamber bottom end face also is provided with oil outlet; Also be provided with end cap between rotating shaft and the rotating shaft fixture, end cap forms a surplus oily cavity volume that is communicated with oil outlet with the axle sleeve bottom; The utility model preferentially adopts oil outlet to be located in the oil groove.During assembling, air and unnecessary damping oil are expelled to surplus oily cavity volume from oil outlet, and no pressure in the axle sleeve chamber is convenient to assembling, and is prevented because of the too high leakage of oil of cavity pressure.
For make climb over the journey back segment on the cover plate and the starting stage resistance that falls littler, rotating shaft of the present utility model is inserted on the end face at the rotating shaft top in the axle sleeve and also was provided with the auxilliary groove of oil.
When the utility model on the cover board turned over just section, damping oil pushed away the oil-through hole baffle plate, and damping oil passes through from oil-through hole, and the torsion that the damping oil countershaft produces is little, and resistance is little when turning on therefore, and it is light to lift feel; When translating into back segment, damping oil can be from crossing oil groove, crossing the auxilliary groove of oil and oil-through hole passes through, and the torsion that the damping oil countershaft produces is littler, and the feel of lifting when turning on therefore is lighter, and prevents that cover plate from erecting the back bounce-back.On climb over that damping oil flows into another half chamber from one of them half chamber in the journey.When cover plate fell, the oil-through hole baffle plate was with oil-through hole sealing (the oil-through hole baffle plate is equivalent to an one-way cock), and damping oil can't pass through from oil-through hole.Cover plate falls the starting stage, damping oil can be from crossing oil groove and crossing the auxilliary groove of oil and pass through, under turn over very fast, cross oil groove then gradually by the vanes close of rotating shaft, cross the auxilliary groove of oil gradually by the sealing of the isolation rib of axle sleeve, damping oil only passes through from the gap between the gap between blade and axle sleeve bottom end face, isolation rib and roller end end face, and the torsion that the damping oil countershaft produces increases, the speed that cover plate falls is slack-off gradually, forms the process that falls slowly.
The utility model compact conformation, rotating shaft and blade construction symmetry, the course of work is stressed evenly, is difficult for breaking down.This device also can be by the tightness between adjusting rotating shaft fixture and the rotating shaft with the gap of adjusting blade and axle sleeve bottom end face, the gap that isolates rib and roller end end face, speed oil excessively when control cover plate falls, thereby make this device adjust whereabouts torsion, strengthen suitability of the present utility model according to the difference of cover plate weight.Oil outlet that this device is provided with and surplus oily cavity volume, air and unnecessary damping oil are expelled to surplus oily cavity volume from oil outlet when assembling, and no pressure in the axle sleeve chamber is convenient to assembling, and is prevented because of the too high leakage of oil of cavity pressure.
