Abstract
The utility model discloses a kind of spring rotary damper for pulsator washing machine top cover, comprise there is host cavity main body, be arranged in host cavity sliding cam, the rotating cam coordinated with sliding cam, inner spring, outer spring; Drive sliding cam to move in host cavity by rotating cam rotation and compress inside and outside spring; After rotatory force disappears, inside and outside spring promotion sliding cam outwards moves and makes rotating cam rotate playback and form damping action.And the diameter of inner spring is less than the diameter of outer spring and inner spring is contained in outer spring, thus improve space service efficiency and be conducive to integrally-built miniaturization.
Description
Technical field
The utility model 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.
Utility model content
For the problem and shortage existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of spring rotary damper of the miniaturization be useful on top cover.
For achieving the above object, the utility model can adopt following technical scheme for the spring rotary damper of pulsator washing machine top cover:
For a spring rotary damper for pulsator washing machine top cover, comprise there is host cavity main body, be arranged in host cavity sliding cam, the rotating cam coordinated with sliding cam, one end are resisted against sliding cam and the other end is resisted against outer spring bottom host cavity, one end is resisted against sliding cam and the other end is resisted against inner spring bottom host cavity; Wherein rotating cam rotates and drives sliding cam to move in host cavity; Sliding cam outer surface is provided with some guiding blocks, and the inner surface of main body is provided with and coordinates and the guide channel extended along host cavity depth direction with guiding block; The diameter of described inner spring is less than the diameter of outer spring and inner spring to be contained in outer spring and coaxial with outer spring.
The utility model is compared with prior art: rotated by rotating cam and drive sliding cam to move in host cavity and compress inside and outside spring; After rotatory force disappears, inside and outside spring promotion sliding cam outwards moves and makes rotating cam rotate playback and form damping action.And the diameter of inner spring is less than the diameter of outer spring and inner spring is contained in outer spring, thus improve space service efficiency and be conducive to integrally-built miniaturization, make the utility model be applicable to be arranged on the outside of rotary drum washing machine fold.
Accompanying drawing explanation
Fig. 1 is the stereogram of pulsator washing machine top cover, and illustrates state when fold is opened.
Fig. 2 is the stereogram of the utility model spring rotary damper.
Fig. 3 is the three-dimensional exploded view of the rotary damper of spring shown in Fig. 2.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
Shown in Fig. 1 and Fig. 2, the utility model discloses a kind of spring rotary damper 1 for pulsator washing machine top cover.When on the top cover 2 being arranged on rotary drum washing machine, this spring 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 spring rotary damper 1 can give the effect that fold 21 automatic buffer is closed.
In order to be applicable to the both sides being arranged on fold 21, this spring rotary damper 1 adopts following design.
This spring rotary damper 1 comprise there is host cavity main body 11, be arranged in host cavity sliding cam 12, the rotating cam 13 coordinated with sliding cam 12, one end are resisted against sliding cam 12 and the other end is resisted against outer spring 14 bottom host cavity, one end is resisted against sliding cam 12 and the other end is resisted against inner spring 15 bottom host cavity; Rotating cam 13 is coordinated by mutual cam surface with sliding cam 12, and be set to rotating cam 13 rotate drive sliding cam 12 move in host cavity and compress inside and outside spring; Therefore inside and outside spring promotes outside movement of sliding cam 12 and makes rotating cam 13 rotate playback and form damping action after rotatory force disappears.Rotate to make rotating cam 13 and sliding cam 12 and then can not be rotated and can only slide at depth direction, sliding cam 12 outer surface is provided with some guiding blocks 121, and the inner surface of main body 11 is provided with and coordinates and the guide channel 111 extended along host cavity depth direction with guiding block 121, formed spacing to sliding cam 12 like this and can only slide to compress inside and outside spring or playback at depth direction.When fold 21 is freely closed from open position, this spring rotary damper 1 can produce the effect that damping gives the closedown of fold 21 free buffer like this.And the moment of torsion that this spring rotary damper 1 produced in the starting stage is less, it is initially very fast when the starting stage that fold 21 is closed makes less moment of torsion that fold 21 can be made to rotate, save fold 21 shut-in time, fold 21 closes the moment of torsion that the later stage provides larger, fold 21 closing velocity is slowed down, thus avoids excessive velocities to pound being pressed onto the hidden danger of the hand of client.Described spring rotary damper 1 is also provided with and connects and be fixed on rotating cam 13 front end and extend the plat shaft 16 of main body 11, this plat shaft 16 can form fold 21 with the shaft hole matching that the support in framework 22 is arranged with the axle of framework 22 and be connected, thus fold 21 has damping while can spinning upside down.Described spring rotary damper 1 is also provided with the lid 17 being covered in host cavity opening part, and described plat shaft 16 extends from lid 17, and lid 17 is provided with the axle sleeve 18 of parcel plat shaft 16.The diameter of described inner spring 15 is less than the diameter of outer spring 14 and inner spring 15 to be contained in outer spring 14 and coaxial with outer spring 14, thus improves space service efficiency and be conducive to integrally-built miniaturization.
Please composition graphs 2 again, main body 11 side of described spring rotary damper 1 is provided with and stretches out and bearing of trend second stator 112 vertical with plat shaft 16, and this second stator 112 is bolted on fold 21 side.
