Description
Technical field
The utility model relates to a kind of motorcycle accessories, and especially a kind of chain for Chain conveyer motor bike is anti-touches cushion rubber and mounting structure thereof.
Background technology
Chain conveyer motor bike is a kind of motor bike by chain transmission campaign and power, is often applied to men car and beam bending bicycle; Wear and tear when relaxing for preventing chain reel cage, causes rocking arm corrosion or damage and then have influence on the safety performance of vehicle, usually reel cage arm corresponding below chain can be installed that chain is anti-touches cushion rubber.Traditional chain prevents that tactile cushion rubber respectively arranges 2 mushroom head card convexs 5 ' at upper and lower semi-body, with reference to Fig. 7, the upper and lower surface of reel cage arm 12 ' then respectively correspondence through hole is set, during installation, 4 of upper and lower semi-body card convexs 5 ' are buckled in upper and lower through hole corresponding to reel cage arm respectively, being fixedly connected with of cushion rubber and reel cage can be realized.The installation of this structure is convenient not, and requires high to mushroom head card convex 5 ' with the quality of fit of corresponding through hole in processing, needs between the two to adopt interference fit, if but the magnitude of interference is little, then more easily come off, and the magnitude of interference is large, needs again to beat just can snap in; Even so, in use procedure, also easily get loose phenomenon because of clamping inefficacy or wear and aging, cause cushion rubber bottom to come off and be involved in chain, produce potential safety hazard.
Utility model content
In order to solve the problem, the utility model provides the anti-tactile cushion rubber of a kind of improved chain and mounting structure thereof.
The utility model solves the technical scheme that its technical matters adopts:
A kind of improved chain is anti-touches cushion rubber, it comprise be set in reel cage shaft cover shaft part, protect in the stage casing of reel cage arm outside face and the rear that is fixed on reel cage arm, described cushion rubber is an annular closed lasso, its rear extends closure to reel cage arm side, described closure is provided with the through hole I for wearing fastener.
Preferably, described cushion rubber is the annular closed lasso of global formation; Described die head is that head and the tail engage the annular closed lasso formed; Described cover shaft part is provided with the positive stop end extended inside reel cage.
The upper and lower both sides of described cushion rubber extend encircle reel cage arm buckle arm.
A mounting structure for tactile cushion rubber prevented by chain, comprises cushion rubber and reel cage, and the reel cage arm of described reel cage is provided with through hole II, and cushion rubber, through the through hole I on described through hole II and cushion rubber, is fixed on reel cage arm by fastener.
The beneficial effects of the utility model are: the anti-cushion rubber that touches of chain of the present utility model adopts annular closed ferrule arrangement, tail end is closed together, first cover shaft part is sleeved on the shaft of reel cage during assembling, with fastener, the closure of rear is fixed on reel cage arm side again, once fix and can complete, low to requirement on machining accuracy, and assemble solid and reliable, the cushion rubber bottom that conventional mounting structure can be avoided to cause because fixedly getting loose inefficacy comes off and is involved in the danger of chain, reduces potential safety hazard.

Detailed description of the invention
Referring to figs. 1 through Fig. 6, a kind of improved chain is anti-touches cushion rubber, it comprise be set in reel cage 1 shaft 11 cover shaft part 21, protect in the stage casing 22 of reel cage arm 12 outside face and the rear 23 that is fixed on reel cage arm 12, described cushion rubber 2 is an annular closed lasso, its rear 23 extends closure 24 to reel cage arm 12 side, described closure 24 is provided with the through hole I 3 for wearing fastener 4.
Chain prevents that the mounting structure of tactile cushion rubber is: the reel cage arm 12 of reel cage 1 is provided with through hole II 13, and cushion rubber 2, through the through hole I 3 on described through hole II 13 and cushion rubber 2, is fixed on reel cage arm 12 by fastener 4.
Cushion rubber 2 of the present utility model adopts annular closed ferrule arrangement, tail end is closed together, first cover shaft part 21 is sleeved on the shaft 11 of reel cage 1 during assembling, with fastener 4, the closure 24 of rear 23 is fixed on the side of reel cage arm 12 again, once fix and can complete, low to requirement on machining accuracy, and assemble solid and reliable, the cushion rubber bottom that conventional mounting structure can be avoided to cause because fixedly getting loose inefficacy comes off and is involved in the danger of chain, reduces potential safety hazard.And the annular closed ferrule arrangement of cushion rubber 2, can be global formation, also can be engaged by cushion rubber head and the tail shown in Fig. 8 to be formed, and loads fastener 4 at joint overlapping, is fixed on reel cage arm 12 by cushion rubber 2.
In the present embodiment, for making cushion rubber 2 more firm on reel cage wall, the both sides up and down of cushion rubber 1 all extend encircle reel cage arm 12 buckle arm 25, preferably, described button arm 25 is arranged at front end, stage casing 22 near cover shaft part 21 place, prevents cover shaft part 21 from moving outside reel cage 1, simultaneously, button arm 25 and closure 24 lay respectively at the both ends in stage casing 22, form double locking mechanism, avoid getting loose of cushion rubber further.
The shaft 11 of reel cage 1 is provided with the collar 14, and cushion rubber 2 overlaps shaft part 21 and is provided with the positive stop end 26 extended inside reel cage 1, and positive stop end 26 is connected on the collar 14, prevents cover shaft part 21 to reel cage 1 medial movement.
As preferred embodiment of the present utility model, fastener 4 can adopt expansion anchor, like this, without the need to bolt, fastening nuts when cushion rubber is installed, is convenient to assembling, implements low cost of manufacture.
The utility model structure is simple, and be easy to processing and manufacturing, convenience quick for installation, firmly not easily gets loose, and good reliability is suitable for large range promotion use.
