Abstract
The utility model belongs to the technical field of automobile spare parts and particularly relates to a rotation damper casing. The rotation damper casing comprises a casing body, a through shaft hole is arranged at the center of the casing body, a ring-shaped damping cavity which is coaxial with the shaft hole is arranged on the casing body, the lower end of the damping cavity is sealed, and an open seal step is arranged at the upper end of the damping cavity. The damping cavity is used for injecting damping oil and matched with a rotation core to exert a damping effect, so that by means of the way, damping effects are good and long; and the seal step can be matched with a seal ring to seal the damping oil, so that service life of a damper is further prolonged.
Description
Technical field
The utility model belongs to the auto-parts technical field, relates in particular to a kind of rotation damper shell.
Background technique
The rotation damper that is used for handle of automobile roof or position like that of prior art, generally be installed on the running shaft of handle, the general structure of this class damper by with cavity housing and the rotor that is arranged in the shell cavity consist of, and be marked with damp liquid in the cavity.The rotor structure of this type of damper has varied, the rotor of a plurality of axial tooths is set such as outer wall, damping is fine when just bringing into use, but after repeatedly using, engender the space between epitrochanterian axial tooth and the damp liquid, cause weakening near the damp liquid tension force of rotor axial tooth corresponding rotor deattenuation when housing rotates, use a period of time rear damper just to lose its damping function, caused using effect very undesirable.
The model utility content
The utility model provides a kind of novel structure and can make lasting, the uniform rotation damper shell of damper damping.In order to realize the foregoing invention purpose, the utility model has adopted following technological means:
A kind of rotation damper shell comprises housing; The axis hole of described housing center for connecting; The damping cavity that an annular be set coaxial with axis hole on the described housing; The sealing of described damping cavity lower end, the upper end arranges the sealed step of an opening.
One circle draw-in groove is set on the outer wall waist of described housing;
Positioning block vertically is set one on the outer wall of described housing.
The beneficial effects of the utility model are: utilize damping cavity to inject damping oil and cooperate the generation damping function with rotary core, such mode damping is well lasting; The setting of sealed step can with seal ring fitted seal damping oil, further prolong working life of damper.
Description of drawings
Fig. 1 is the structural representation of a kind of rotation damper shell of the utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the preferred implementation of a kind of rotation damper shell of the utility model is made detailed description:
As depicted in figs. 1 and 2, this rotation damper housing main body is housing 6, and housing 6 is substantially cylindrical, and its center has the axis hole 3 of a up/down perforation, in order to adapt to the external shaft rotation.Also offer a circular damping cavity 2 on the housing 6, damping cavity 2 and axis hole 3 coaxial arrangement.The sealed bottom of damping cavity 2, the upper end portion is opened wide.
Be positioned at the position at damping cavity 2 tops on the housing 6, be provided with a sealed step 1 coaxial with axis hole 3, sealed step 1 establish seal ring in order to card, prevent that damping oil from leaking outside.
Waist location on the outer wall of housing 6 is provided with one and encloses the draw-in groove 5 of indent, in order to the axial position of stationary housing 6.Be provided with vertically the positioning block 4 of one section evagination on the outer wall of housing 6, in order to prevent housing 6 rotations.The combination of draw-in groove 5 and positioning block 4 can be with the mounting point of being fixed in of shell stability.
Utilize damping cavity 2 to inject damping oil and cooperate the generation damping function with the rotary core of damper, such mode damping is well lasting; The setting of sealed step 1 can with the seal ring fitted seal damping oil of rotary core, further prolong working life of damper.
Claims (3)
