Description
Technical field
The present invention relates to machine design field, particularly a kind of damper on pulsator washing machine top cover.
Background technology
Washing machine cover lid assembly of the prior art, comprises top cover body and to be installed on top cover body and top cover body is opened or closed fold relatively.Existing this washing machine cover lid assembly, when user needs to close fold in use, owing to not having the means cushioned, fold can naturally fall, and so just exists and closes because misoperation falls when fold and damage user.The damping adopting damper to realize fold upset can solve the problem preferably, but due to the thickness of top cover less, need to design the miniaturized damper being applicable to top cover and can be useful in rotary drum washing machine.
Therefore, need a kind of new technical scheme to solve the problem.
Summary of the invention
For the problem and shortage existing for above-mentioned prior art, the object of this invention is to provide a kind of fluid pressure type rotary damper of the miniaturization be useful on top cover.
For achieving the above object, the present invention can adopt following technical scheme for the fluid pressure type rotary damper of pulsator washing machine top cover:
For a fluid pressure type rotary damper for pulsator washing machine top cover, the lid comprise sleeve, inserting the rotating shaft in sleeve and cover outside sleeve; Described rotating shaft is provided with the first blade and the second blade that relatively extend; First blade is provided with the first sealing strip, the second blade is provided with the second sealing strip; Described first sealing strip and the second sealing strip are all resisted against the inner surface of sleeve; Seal in described sleeve and be filled with hydraulic oil; Sleeve bottom is provided with the circulation groove for hydraulic oil circulation.
The present invention is compared with prior art: the hydraulic oil receiving space formed by first, second sealing strip, and is filled with hydraulic oil in receiving space, and hydraulic oil is circulated by circulation groove, because the viscosity of hydraulic oil is large, circulation groove is less, hydraulic oil circulation difficulty, thus produces damping.This integrally-built miniaturization, make the present invention be applicable to be arranged on the outside of rotary drum washing machine fold, and hydraulic oil takies the width spaces of sleeve and does not need sleeve extra hand hydraulic oil be squeezed in sleeve bottom and take length space, is also conducive to miniaturization.This damping all works in fold opens and closes.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, following detailed description of the invention should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
Shown in Fig. 1 and Fig. 2, the present invention discloses a kind of fluid pressure type rotary damper 1 for pulsator washing machine top cover.When on the top cover 2 being arranged on rotary drum washing machine, this fluid pressure type rotary damper 1 is contained in the both sides (in Fig. 1 A position) bottom fold 21 and forms axle with the support (not shown) that the framework 22 of top cover 2 is arranged and is connected, like this when fold 21 will be returned to closed position from open position, namely fluid pressure type rotary damper 1 can give the effect that fold 21 automatic buffer is closed.
Refer to shown in Fig. 2 to Fig. 4, in order to be applicable to the both sides being arranged on fold 21, this fluid pressure type rotary damper 1 adopts following design.
This fluid pressure type rotary damper 1, the lid 12 comprise sleeve 11, inserting the rotating shaft 13 in sleeve 11 and cover outside sleeve.Described rotating shaft 13 is provided with the first blade 15 and the second blade 16 relatively extended; First blade 15 is provided with the first sealing strip 151, second blade 16 and is provided with the second sealing strip 161.Described first sealing strip 151 and the second sealing strip 161 are all resisted against the inner surface of sleeve 11.Seal in described sleeve 11 and be filled with hydraulic oil (not shown).The circulation groove 111 for hydraulic oil circulation is provided with bottom sleeve 11.By the hydraulic oil receiving space that first, second sealing strip 151,161 is formed, and be filled with hydraulic oil in receiving space, hydraulic oil is circulated by circulation groove 111, because the viscosity of hydraulic oil is large, circulation groove 111 width is less, hydraulic oil circulation difficulty, thus make the first blade 15 and the second blade 16 rotate fast and can only slowly to rotate under the resistance of hydraulic oil, thus produce damping.This damping all works in fold 21 opens and closes.
Further, in order to better provide damping, described sleeve 11 inwall is also provided with the interior flank 112 extended internally for a pair, and this is respectively the first sealing strip 151 and the second sealing strip 161 in both sides of flank 112 in two, has gap between described interior flank 112 and rotating shaft 13.So not only between two sealing strips 151, there is receiving space, more complicated circulation environment is formed between flank 112 and two sealing strips 151 in two, hydraulic oil is not only circulated by circulation groove 111 simultaneously, also can be circulated by the gap had between interior flank 112 and rotating shaft 13.Further improve the currency of hydraulic oil and produce larger damping.
This fluid pressure type rotary damper 1 is used in after in fold 21, the damping releasing effect of hydraulic oil is slowly steady, when fold 21 is repositioned to closed downwards, fold 21 is made comparatively slowly and stably to improve Consumer's Experience, can be comparatively applicable to the use of rotary drum washing machine by return.This fluid pressure type rotary damper 1 total is miniaturized, and especially more helpful to reducing of sleeve 11 internal diameter, when fold 21 thickness is less, the sleeve 11 of less internal diameter is conducive to collecting and is arranged on fold 21 side.In the present embodiment, the head of described rotating shaft 13 is provided with the axocoel 17 inserted for abutment shaft (not shown), therefore when the fluid pressure type rotary damper of this embodiment is arranged on the top cover 2 of rotary drum washing machine, support can be set in framework 22 and stretches out abutment shaft and insert in axocoel 17 and form fold 21 and to be connected with the axle of framework 22 thus fold 21 has damping while can spinning upside down.Certainly, in other embodiments, also coaxially can connect at the head of rotating shaft 13 and stretch out installation shaft, such support only needs correspondence to arrange axis hole also can realize axle connection, identical with present embodiment effect, does not repeat them here.Sleeve 11 side is also provided with and stretches out and bearing of trend first stator 14 vertical with fixed axis 13, and this first stator 14 is bolted on fold 21 side.
As shown in Figure 3, owing to there being hydraulic oil wherein, therefore the part of sealing comprises, and described sleeve 11 is fixed by the bolt 18 inserted after sleeve 31 in sleeve 31 with rotating shaft 13, and the part that bolt 18 inserts is provided with sealing ring 181.The outside projection in front end of described fixed axis 13 has sealing ring 19, jointly forms the hydraulic oil memory space sealed bottom described sealing ring 19, first sealing strip 151, second sealing strip 161 and sleeve 11.Outside described sealing ring 19, cover has sealing ring 191 further, accompanies some lining pads 192 between sealing ring 191 and lid 12.
