Description
Technical field
The utility model relates to a kind of Slow-falling devices.
Background technique
The many occasions of Slow-falling device application in daily life, such as toilet lid.Traditional Slow-falling device generallys use
Blade shape is realized by the way that oil-gap was arranged in blade or shaft or shell inner cavity and falls process slowly.Traditional blade
Formula is fallen slowly, and when using certain number, with the abrasion of part, crossing oil-gap can be become larger, and crosses oil-gap to the resistance of oil
Become smaller, fall slowly the time can shorten in addition Slow-falling device failure.
Summary of the invention
The utility model is in order to solve the above technical problems, provide a kind of Slow-falling device, including shell, shaft, two leaves
Piece and end cap.
Wherein, the shell is equipped with inner cavity, interior intracavitary filling damping oil, and the wall surface of inner cavity is equipped with the limit of rotational symmetry
Plate.The shaft is equipped with the oil baffle and positive stop lug boss of rotational symmetry, and positive stop lug boss outer diameter is equal to housing cavity internal diameter, described
Oil baffle in the middle part of be equipped with oil scupper.The blade, which is equipped with limiting slot corresponding with oil baffle and oil extraction face, limiting slot, to be had
Two sides, the oil extraction face are arranged on the one side of limiting slot, on the corresponding oil baffle in the position in oil extraction face
Oil scupper, the area in oil extraction face are greater than the area of oil scupper and are covered.The end cap is equipped with shaft installation through-hole, shaft peace
The diameter of through-hole is filled between the positive stop lug boss and shaft diameter.
When installation, blade is mounted on the oil baffle of shaft, and blade and shaft install vaned one end and be built in shell
Inner cavity in, the other end of shaft extends the inner cavity of shell, and end cap connected with outer casing is set in shaft by shaft installation through-hole
On, and limited shaft in the housing by positive stop lug boss.The blade includes binding face, and binding face is curved surface, outer diameter
Equal to the internal diameter of housing cavity, after installation, binding face abuts the wall surface of housing cavity；Oil was offered on the binding face
Slot can fall speed requirement according to customer requirement slowly, design the oil groove excessively of different number and size, and corresponding mold is changed
Small, relatively other change modes are at low cost.
The use of the Slow-falling device is divided into closing course and opening procedure.When the Slow-falling device is mounted in toilet lid,
Its closing course is exactly the closing course of toilet lid, needs to fall slowly, and opening procedure is exactly the opening procedure of toilet lid, needs to hinder
Power very little realizes Rapid opening.
When closure, shaft rotation, damping oil impacts oil extraction face, and oil extraction face is fitted on oil scupper, closes oil scupper, slows down
Damping oil is realized and is fallen slowly in the flowing on blade both sides.
When opening, shaft rotation, damping oil impacts oil extraction face by oil scupper, and oil extraction face generates Light deformation, formed oil
Gap accelerates damping oil in the flowing on blade both sides, realizes Rapid opening.
Further, in two sides of the limiting slot of the blade, the side opposite with the oil extraction face opened up oil
Channel, the position of the oil passage correspond to the oil scupper of the oil baffle.By controlling the size of oil passage, can design
The Slow-falling device of different slow terminal-velocity degree out.

The amplitude of fluctuation in oil extraction face is bigger.
Further, the blade includes extension edge, face where the extension edge vertical row pasta, and extends oil extraction face
Place face forms frame, and when damping oil impact oil extraction face place face place face and the frame, frame deformation is expanded outwardly,
Frame is bonded closer abrasion between automatic compensation blade and shell with the inner wall of shell, extends the service life fallen slowly.
Further, the face in the shaft between two oil baffles is working face, and working face is connected two blades, point
For oil extraction curved surface and oily curved surface is kept off, when the blade is mounted on oil baffle, the work of the one end in oil extraction face is equipped with close to blade
Face is to keep off oily curved surface.The end of the limit plate is curved surface, rotating shaft, the end abutment for keeping off oily curved surface and limit plate,
There is gap in the end of the oil extraction curved surface and limit plate.When closing, it is closed early period, the end of limit plate corresponds to oil extraction curved surface,
It is closed the later period, the end of limit plate is corresponding to keep off oily curved surface, so the oil extraction speed for being closed early period is greater than the oil extraction speed in closure later period
Degree realizes that Slow-falling device is fallen slowly and hurtles down early period, slow to fall behind the slow drop of phase realization.When open, early period, the end of limit plate are opened
Portion is corresponding to keep off oily curved surface, opens the later period, and the end of limit plate corresponds to oil extraction curved surface, beats so the oil extraction speed for opening early period is less than
Open the oil extraction speed in later period.
Further, the axle center of the shaft is equipped with and draws glue hole, draws glue hole and is conducive to avoid shaft shrink bring knot
Structure size changes.
Further, the thickness of the oil baffle is less than the width of the limiting slot.
Further, the positive stop lug boss is equipped with a seal groove, and it is sliding with housing cavity wall surface that one is equipped in the seal groove
The sealing ring of dynamic cooperation.
From the above description of the utility model, it can be seen, compared to the prior art, the utility model has the advantages that
By the cooperation of the oil scupper on oil extraction face on blade and shaft, in opening procedure, damping oil by oil scupper,
The oil extraction face of impact, oil extraction face generate Light deformation, form oil-gap, realize and quickly open.When to be closed, damping oil impact row
Pasta, oil extraction face cover oil scupper, and realization is fallen slowly, and the utility model structure is simple, easy to process, while utilizing oil extraction mask
The performance of flexible deformation compensates for the abrasion at traditional blades edge and shell relative motion generation, overcomes the prior art
Defect.
