Description
Technical field
The utility model relates to a kind of shock-proof front-fork assembly, and particularly a kind of shock-proof front-fork assembly for bicycle, belongs to bicycle accessories technical field.
Background technology
Along with improving constantly of people's living standard, Green Travel, recreation and body-building have become the one way of life mode of people's daily life, the important means that bicycle is this life style.For the cyclist of bicycle can comparatively cosily be travelled at broken terrain, a lot of bicycles have all adopted the front fork with incabloc function.
At present, the main attaching parts slide shaft of bicycle shock-proof front-fork assembly exists two shortcomings: 1, fixedly the area of contact of sliding sleeve and slide shaft is little, and more single, and the easy like this movement causing radially has a strong impact on the function of shock-proof front-fork assembly.2, endwisely slip single stressedly, easily produce potential safety hazard.
Summary of the invention
The utility model provides a kind of shock-proof front-fork assembly.
For achieving the above object, the technical solution adopted in the utility model is: a kind of shock-proof front-fork assembly, comprises fixedly fixedly sliding sleeve, slide shaft, damping spring spring fixed seat, damping spring spring retaining sleeve pipe and damping spring of sliding sleeve, second of outer tube, first; Described first fixedly sliding sleeve be fixed on the middle part of the inner chamber of described outer tube, one end of the inner chamber of described outer tube is provided with and the described second fixedly sliding sleeve installation portion that fixedly sliding sleeve profile is mated, described second fixedly sliding sleeve be located in described fixedly sliding sleeve installation portion, described damping spring spring fixed seat is sheathed on one end of the close described fixedly sliding sleeve installation portion of described outer tube, and by described second fixedly sliding sleeve be encapsulated between described fixedly sliding sleeve installation portion and damping spring spring fixed seat; Described first fixedly sliding sleeve and second fixedly sliding sleeve all offer the through hole that cross section is arch, described slide shaft is provided with the first shaft part and the second shaft part; The profile of described the first shaft part with described first fixedly the shape of through holes of sliding sleeve mate, the profile of described the second shaft part with described second fixedly the shape of through holes of sliding sleeve mate, described slide shaft slides on described first with the first shaft part, and fixedly sliding sleeve, the second shaft part slide on described second and fixedly in sliding sleeve, arrange; Described damping spring fixed sleeving and damping spring are all sheathed on described slide shaft, and one end of described damping spring and described damping spring spring fixed seat are conflicted and arranged, and the other end and described damping spring spring retaining sleeve pipe are conflicted and arranged.
Preferred technical scheme is: the end that described slide shaft is positioned at the inner chamber of described outer tube is fixed with lock screw.
Preferred technical scheme is: the described first string of arch that fixedly string and described second of the arch of the through hole of sliding sleeve is determined the through hole of sliding sleeve is oppositely arranged.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, because the utility model increases horizontal area and the longitudinal area that fixing sliding sleeve (comprise first fixedly sliding sleeve and the second fixing sliding sleeve) contacts with slide shaft, thereby avoided moving radially of slide shaft;
2,, because the utility model has increased slide shaft stress point in axial sliding, therefore improved the safety performance of shock-proof front-fork assembly.
