Description

The anti-vibration structure of bicycle support body

The utility model relates to a kind of anti-vibration structure of bicycle support body.

Bicycle adopts the shock-absorbing design structure at present, mostly is to do structural variation in forward and backward breeches pipe body, makes it when running into Uneven road, then can utilize this forward and backward breeches pipe body to absorb the jarring forces that wheel touches, and plays the buffer action of appropriateness.Though this kind structure design truly has effect, but because and reckon without car load support body itself and also its damping capaicty need be arranged, could fully reach comfortable, security purpose, therefore, though then can find to utilize this forward and backward breeches pipe body to absorb the jarring forces that wheel touches virtually, when also causing whole desire own can't mediate human body when Uneven road in time to drive weight press on the strength of vehicle body relatively.Therefore also has a kind of oil hydraulic cylinder that to do flexible shape that in support body, installs, it is provided allays vibrations and reaches shock-proof effect, yet the action of this oil hydraulic cylinder is to keep straight line to shrink or elongated condition, though when support body is given a shock pressure again, can in time slows down or get rid of the strength of its suffered shake, but its oil hydraulic cylinder both sides institute pivot part absorbs this jarring forces on the contrary, so that cause its jarring forces to concentrate on this articulated section, formation also constitutes the prestige association to rider's safety virtually to the destruction danger of whole vehicle frame and oil hydraulic cylinder.

The purpose of this utility model provides a kind of shock-absorbing, shock-proof effect is good, and assembling and dismantling are the anti-vibration structure of bicycle support body easily.

The utility model is described in further detail below in conjunction with accompanying drawing.

Shown in Fig. 1,2,4, the utility model is at the structure of bicycle whole frame body shock-proof effect, union lever 11 at hack lever 1 end of going forward of vehicle frame 1A, be shaped on preceding thread section 111, smooth surface 112, rear thread section 113 and concave ring groove 114 respectively, make it install a limit screw cap 2, spring coil 3 and dustproof sleeve 4 and location resilient ring 5 and preceding reinforced sheet 6 respectively at preceding thread section, smooth surface, rear thread fragment position place, run through in the through hole 122 of the binding sleeve 121 by seat bar 12 (is preferable with slotted hole) by rear thread section and concave ring groove more afterwards; And this limit screw cap 2 is locked on the preceding thread section 111 of union lever 11 by negative thread 21, make it can be spacing by spring coil 3 snare clamping stagnations, and the rolling of unlikely generation pine is shaken, dustproof sleeve 4 is located at spring coil 3, behind the limit screw cap 2, and by two end interfaces 41,42 are placed on respectively between the terminal and union lever 11 preceding thread sections of the hack lever 1 of going forward and locate, on the location resilient ring 5 ring edge 51, so that dustproof effect to be arranged really, and location resilient ring 5 is hollow form, by encircling the type moulding that edge 51 and flange 52 are constituted, its ring edge 51 combines with dustproof sleeve 4 one end interfaces 42, hollow flange 52 then is inserted in combination mutually with a hollow flange tube 61 of preceding reinforced sheet 6, and hollow flange tube 61 is spacing with spring coil 3 formation clamping stagnations, the rolling of unlikely generation pine is shaken; Preceding reinforced sheet 6, the position is in through hole 122 1 external side ends of the binding sleeve 121 of seat bar 12, it is the hollow form moulding (is preferable with slotted hole) of holding concurrently of semicircle concave arc, forming the rolling of spacing, the unlikely generation pine of clamping stagnation by hollow flange tube 61 clamping stagnation spring coils 3 shakes, reinforced sheet 6 ｀ then, be position another external side end of through hole 122 (is preferable with slotted hole) in the binding sleeve 121 of seat bar 12, it is the hollow form moulding of holding concurrently of semicircle concave arc; Elastic ring 7 is hollow form, with the position between back reinforced sheet 6 ｀ and hold-doun nut 8, hold-doun nut 8, place between elastic ring 7 and the adjustment nut 9, what make its cooperation adjustment nut 9 supplies displacement and the force variation of adjustable spring coil 3, adjust nut 9, place between hold-doun nut 8 and the C shape latch closure 9A, the force variation of adjustable spring coil 3 with the confession displacement that cooperates hold-doun nut 8, C shape latch closure 9A places the concave ring groove 114 of union lever 11, can be union lever 11 after linking the through hole 122 of sleeve 121 through seat bar 12-, button stagnates spacing again, after the rear thread section 113 of union lever 11 penetrates into the through hole 122 of a bar 12 1 binding sleeves 121, pass again one be the elastic ring 7 of back reinforced sheet 6 ｀ of hollow form and a hollow circular ring after, a hold-doun nut 8 and adjustment nut 9 again are spirally connected, and stagnate in the concave ring groove 114 (as shown in Figure 3) of union lever 11 by C shape latch closure 9A button, and cooperate preceding binding hack lever 13 to be shaped on the pivot joint tube 131 of a hollow form, being placed on the back links in the hack lever 14-U shape pivot joint tube 141, and articulate the both sides circle perforation 142 that tube 131U shape articulates tube 141 by this hollow form of running through of a screw rod 1B, combine with nut 1C more spacing (as shown in Figure 4).

So, when running into Uneven road again, then articulating 131 in tube by preceding union lever 13 is incorporated into the back and links hack lever 14-U shape and articulate tube 141 and constitute and swing action, and cooperate a limit screw cap 2, spring coil 3 of 11 combinations of this preceding union lever, dustproof sleeve 4, location resilient ring 5, preceding reinforced sheet 6, link sleeve 121, back reinforced sheet 6 ｀, elastic ring 7, hold-doun nut 8, adjust nut 9, and be the projection shape in time, promptly as shown in Figure 5: make its whole frame body 1A thereby purely and simply allay the jarring forces that is touched.

For cooperating various car type framework to form, can change seat bar 15 into pressure-bearing type, it is provided with the through hole 152 (is preferable with slotted hole) of a binding sleeve 151 simultaneously, and union lever 11 similarly installs a limit screw cap 2 before making, spring coil 3, dustproof sleeve 4, location resilient ring 5, the hollow flange 52 of its location resilient ring 5 is placed on the hollow flange tube 6A1 of positioning convex ring 6A, clamping stagnation spring coil 3 spacing and unlikely generation pine rollings by hollow flange tube 6A1 are shaken, the seat bar 15 1 that the protruding barrel mast 6A3 of the other end hollow of positioning convex ring 6A then is inserted in pressure-bearing type links in sleeve 151 through holes 152, and be butted on through hole 152 outer rims by bulge loop 6A2 wherein and be the location, again by elastic ring 7, hold-doun nut 8, adjust nut 9 it is inserted in combination in binding sleeve 151 through holes 152, as Fig. 6,7, shown in 8, make its whole frame body 1A adopt structure like this and purely and simply allay the jarring forces that is touched.

Adopt the advantage of technical solutions of the utility model as follows, it can really reach rapid shock-proof effect, assembles or disassemble simple and convenient.
