Abstract
The utility model relates to a sealing element, and particularly relates to an inverted-V-shaped locating asymmetric corrugated spacer bush. The inverted-V-shaped locating asymmetric corrugated spacer bush comprises a top circular hole and a hooping groove at the bottom, wherein the top circular hole and the hooping groove are in transition connection through corrugated rubber, the central axis of the top circular hole is the central axis of the corrugated spacer bush, an inverted-V-shaped locating asymmetrical bottom surface is formed on the bottom surface of the hooping groove, the hooping groove is asymmetrical relative to the central axis of the spacer bush, the corrugated rubber is also asymmetrical relative to the central axis of the spacer bush and can be compressed, and the inverted-V-shaped locating asymmetrical bottom surface is asymmetrical relative to the central axis of the spacer bush. The inverted-V-shaped locating asymmetric corrugated spacer bush is simple in structure and convenient to install and has a good sealing effect.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of asymmetric formula ripple spacer.
Background technique
Existing speed change lever gearshift position is dissymmetrical structure, the dirt-proof boot that is used for speed change lever gearshift position is generally common spacer, and as shown in Figure 1, common spacer mostly is symplex structure, cause common spacer to carry out Matching installation with snap-ring groove, do not reach effectively dustproof effect.
The model utility content
The purpose of this utility model is to have proposed a kind of inverted v-shaped bad seek and claims formula ripple spacer, and it is simple in structure, is convenient to install good sealing effect.
the utility model is to adopt following technological scheme to realize: a kind of inverted v-shaped bad seek claims formula ripple spacer, comprise top circular hole and the snap-ring groove that is positioned at bottom, connect by corrugated rubber transition between top circular hole and snap-ring groove, the central axis of top circular hole is the central axis of this ripple spacer, wherein, the bottom surface of snap-ring groove is provided with bottom surface, asymmetric inverted v-shaped location, snap-ring groove is asymmetric setting with respect to the central axis of spacer, corrugated rubber phase also is asymmetric setting for the central axis of spacer, and corrugated rubber is compressible, the formation of bottom surface, asymmetric inverted v-shaped location is inverted v-shaped, and the central axis with respect to spacer is asymmetric setting.
In the utility model, described snap-ring groove and bottom surface, asymmetric inverted v-shaped location are integral structure.
The beneficial effects of the utility model are: because snap-ring groove and corrugated rubber are asymmetric setting, so this spacer is convenient to be arranged on shifting shaft, and can swing with the action of shifting shaft, play seal action preferably.
Description of drawings
Fig. 1 is the sectional view of existing common spacer;
Fig. 2 is main sectional view of the present utility model;
Fig. 3 is sectional view of the present utility model.
In figure: 1 top circular hole; 2 corrugated rubber; 3 snap-ring grooves; 4 bottom surface, asymmetric inverted v-shaped location.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figures 2 and 3, this inverted v-shaped bad seek claims formula ripple spacer to comprise top circular hole 1 and is positioned at the snap-ring groove 3 of bottom, connects by corrugated rubber 2 transition between top circular hole 1 and snap-ring groove 3.Top circular hole 1 is used for gearshift axial region location, and and axle between be interference fit, the central axis of top circular hole 1 is the central axis of this ripple spacer.The bottom surface 3 of snap-ring groove is provided with bottom surface 4, asymmetric inverted v-shaped location, and the shape of bottom surface 4, asymmetric inverted v-shaped location is inverted v-shaped, and with respect to the central axis of spacer, is asymmetric setting.Accordingly, along the snap-ring groove 3 of this bottom surface moulding, with respect to the central axis of spacer, be asymmetric setting, while being used for installing, the clip location, quick and easy for installation.Simultaneously, the corrugated rubber 2 between top circular hole 1 and snap-ring groove 3 also is asymmetric setting with respect to the central axis of spacer, and corrugated rubber 2 is compressible.Therefore this spacer can swing with the action of shifting shaft, can play preferably seal action.
In the present embodiment; the relativeness that is described as to top circular hole 1 and bottom snap-ring groove 3 position relationships; be the two ends that top circular hole 1 and snap-ring groove 3 lay respectively at spacer; therefore the restriction of its position relationship is not limited to the described top of the present embodiment and bottom; same or analogous in all its position relative relations and the present embodiment, all drop in protection domain of the present utility model.
