Description
The utility model relates to the bicycle supporting device, especially bicycle damper.
In the prior art, to the bumper of bicycle use, comparatively advanced is that the disclosed name of Patent Office of the People's Republic of China is called: bicycle shock absorption device, the patented technology of the patent No.: 91219877.X.This technical scheme is to insert a slip pole in a cylindrical shell, and what the elastic material of a cushioning effect adopted is metal spring.So it is simple in structure, can play cushioning effect preferably under certain impulsive force.The multiple elastic force after but spring is compressed does not have shock damping action, so under bigger impulsive force, shock absorption device the top shake will occur and cause the stable inadequately problem of damping.In addition, its volume is also bigger, and leak tightness is also poor.
The purpose of this utility model is at the existing in prior technology problem, and provides a kind of elastic material to adopt gas, still can keep stable cushioning effect under large impact power, the vapour-pressure type bicycle use bumper of the little and good seal of a kind of like this volume.
The utility model realizes that by following measure at the bicycle damper that mainly is made of cylindrical shell and moving pole, its characteristics are that described moving pole is a piston rod 2, and an end captive joint of this piston rod 2 piston 7; And piston 7 is contained in the inner chamber of cylindrical shell 5, and the seal ring 6 with cylindrical shell 5 inner wall sealings is housed on piston 7 again; Blanking cover 3 on fixedly be equipped with on the top on the cylindrical shell 5, described piston rod 2 pass then that blanking cover 3 stretches out outside the cylindrical shell 5 on this, on last blanking cover 3, be equipped with the seal ring 4 of cylindrical shell 5 inner wall sealings and with piston rod 2 leak free seal rings 17; Lower plug cover 11 fixedly is equipped with on following top at cylindrical shell 5, inflation valve rod 8 is equipped with at place, axle center at lower plug cover 11, and between inflation valve rod 8 and lower plug cover 11, have valve port 9 to captive joint with lower plug cover 11, seal ring 10 with cylindrical shell 5 inner wall sealings is housed on lower plug cover 11, again with valve port 9 that lower plug cover 11 is captiveed joint on valve rod 8 leak free seal rings 14 are equipped with and inflate; Also have a tubular mounting rod 12 to captive joint in the lower end of lower plug cover 11 in addition with cylindrical shell 5; Fill nitrogen by lower plug cover 11 and last blanking cover 3 osed top cylindrical shells 5 inner chambers; And cylindrical shell 5 osed top inner chambers are separated into pressure-bearing chamber 15 and surge chamber 16 by piston 7.In addition, this programme also has following concrete characteristics, and captiveing joint between promptly described piston rod 2 and the piston 7 is riveted joint.Between described upward blanking cover 3 and the cylindrical shell 5 fixedly is that curved riveting is connected and fixed.Described valve port 9 is riveted joint with captiveing joint of 11 of lower plug covers.Between described lower plug cover 11 and mounting rod 12 and the cylindrical shell 5 fixedly is that curved riveting is connected and fixed.Described seal ring 4 and 17, the seal ring 6 on the piston 7, the seal ring 10 on the lower plug cover 11 and the seal ring of going up on the blanking cover 3 14 on the valve port 9 is the O RunddichtringO.Also be processed with mounting hole 1 on the described piston rod 2.Also be processed with mounting hole 13 on the described mounting rod 12.
The technical program that adopts above-mentioned technical characterictic to constitute is owing to be to adopt gas as elastic material, so can do volume less; And between upper and lower blanking cover and the cylindrical shell except that adopting curved riveting, also have the seal ring sealing, and between piston rod and the inflation valve rod seal ring sealing arranged also, therefore, bumper can be made sealing and non-removable integral body.In the osed top cylindrical shell, fill and to reduce oxidation, increase its service life the O RunddichtringO with nitrogen.Piston is divided into pressure-bearing chamber and surge chamber with the osed top cylinder lumen again, and when being subjected to impulsive force, piston is exerted pressure to the pressure-bearing chamber, and after impulsive force disappeared, the speed that surge chamber then slows down piston reset made that the effect of damping is stable.This shows that this programme has a significant effect than prior art.
Description of drawings:
Fig. 1 partly cuts open scheme drawing for the utility model embodiment's.
Below by a specific embodiment, and the utility model is described in further detail in conjunction with its accompanying drawing.Top on the cylindrical shell 5 with curved rivet clasp fixed one be installed with piston rod 2 on blanking cover 3.This is gone up on the blanking cover 3 and the seal ring 4 of using the O RunddichtringO is housed between the cylindrical shell 5; And the seal ring 17 of 2 useful O RunddichtringOs of piston rod.There are lower plug cover 11 and tubular mounting rod 12 fixed with cylindrical shell 5 curved rivet clasps simultaneously on the following top of cylindrical shell 5.And inflation valve rod 8 is housed at place, the axle center of lower plug cover 11, again and inflation valve rod 8 between riveting adorn one and have the valve port 9 and 8 sealings of inflation valve rod of making seal ring 14 of the O RunddichtringO, and on the lower plug cover 11 and 5 of cylindrical shells the seal ring 10 of using the O RunddichtringO is housed.By last blanking cover 3 and lower plug cover 11 osed top cylindrical shells 5 inner chambers, be divided into pressure-bearing chamber 15 and surge chamber 16 by the piston 7 that is riveted on the piston rod 2, and charge into nitrogen by inflation valve rod 8 therein, and on the piston 7 and the seal ring 6 of 5 useful O RunddichtringOs of cylindrical shell.Needs for using are processed with mounting hole 13 on mounting rod 12 in addition; On piston rod 2, also be processed with mounting hole 1.Thus, constitute the little and complete leak free bicycle use of volume bumper.The bumper of this structure is through 200,000 times compression experiment, and its work done curve does not reduce.Implement this programme except that above-mentioned disclosed technical characterictic, required other technology contents is the known content of those skilled in the art, so do not give unnecessary details.
