Abstract
The utility model discloses a tertiary buffering damper, including base, telescoping cylinder, telescopic link, expanding spring and connecting seat, the telescoping cylinder is located on the base, the telescopic link is corresponding with the cavity of telescoping cylinder, the expanding spring cover is located on the telescopic link, connecting seat and telescopic link upper end is connected, its characterized in that, and it still including flexible packing ring, should be the elastic rubber component by flexible packing ring, and its cover is located between telescopic link and the expanding spring on locating the telescopic link, and telescopic link and expanding spring slide from top to bottom relatively, third to the half of expanding spring length when the thickness of flexible packing ring is non - compression state. The utility model discloses a tertiary shock -absorbing structure science closely combines together, plays the formula cushioning effect for the shock attenuation effect reaches the best.
Description
Technical field
The utility model relates to damping device, particularly a kind of three grades of buffer damping mechanisms.
Background technology
Traditional damping device, generally adopts spring or shell fragment damping, the damping dress of for example bicyclePut general employing spring loop bar structure, the damping of lorry or main equipment is the stacked of multi-disc shell fragmentFormula damping. At present, many other damping devices yet, but following 2 deficiencies of ubiquity:The one, precise structure complexity, though damping effect is good, cost is high, inconvenient maintenance; The 2nd,, knotStructure is very simple, although this damping device cost is low, it is simple to safeguard, damping effect is inadequateDesirable. Therefore, need to research and develop a structure mustn't be too complicated, and cost is moderate, and dampingEffect is damping device preferably.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, a kind of three grades of bumper and absorbing shock machines are providedStructure, closely combines by three grades of shock-damping structure science, plays formula cushioning effect,Make damping effect reach best.
The technical solution adopted in the utility model is: a kind of three grades of buffer damping mechanisms, comprise pedestal,Telescoping cylinder, expansion link, coil tension spring and Connection Block, described telescoping cylinder is located on pedestal, described in stretchContracting bar is corresponding with the cavity of telescoping cylinder, and described coil tension spring is sheathed on expansion link, described connectionSeat is connected with expansion link upper end, it is characterized in that, it also comprises expansion bead, this expansion beadFor elastic rubber member, it is sheathed on expansion link, between expansion link and coil tension spring, andExpansion link and coil tension spring slide up and down relatively; The thickness of described expansion bead is non-compressed stateTime coil tension spring length 1/3rd to 1/2nd.
Further, match with the cavity of telescoping cylinder by piston in described expansion link lower end, described in stretchThe bottom of contracting cylinder cavity is provided with some passages, and those passages are uniformly distributed, and its gross area accounts for to be stretched/ 5th to 1/2nd of a cavity cross-sectional area of contracting cylinder.
Further, the upper end of described telescoping cylinder is provided with stepped flange, described coil tension spring lower end coverBe located on flange, withstand ladder position.
Further, the upper end of described expansion link is fixed and is connected by screw rod bolt arrangement and Connection BlockConnect, the bottom surface of Connection Block is withstood in the upper end of described coil tension spring.
Further, the lateral surface of described expansion bead is concavo-convex wave knot alternate and transition graduallyStructure or concavo-convex screw-type structure alternate and transition gradually. The outside of expansion bead is wave or spiral shellLine formula, can increase elastic compression and the return performance of packing ring to greatest extent, makes expansion padCircle there is preferably effect and life-span. Because pure columned packing ring, it is in continuous compressionAfter, easily lost efficacy.
The utlity model has following advantage: be closely combined in one by three grades of shock-damping structure scienceRise, play formula cushioning effect, make damping effect reach best. At three grades of bumper and absorbing shock machinesWhen structure is suddenly stressed, telescoping cylinder matches with expansion link, plays the effect of one-level damping, buffering,If power is larger, spring-compressed is to certain state, play secondary damping telescoping cylinder, expansion link,Effect, if dynamics is very large, expansion bead compression, plays the effect of three grades of damping, bufferings.Expansion bead is movable to be arranged, and both can overcome the stiff sense of that unexpected pause and transition in rhythm or melody of retaining washer, andSeparate the direct friction between coil tension spring and expansion link, in addition, the length of expansion bead is set toWhen non-compressed state 1/3rd of coil tension spring length to 1/2nd, after tested, can playBest damping, buffering effect, and be life-span of whole three grades of buffer damping mechanisms to reach best.Test discovery, if the length of expansion bead is too short, the decrement of coil tension spring is just large so, warpAfter crossing repeatedly compression, coil tension spring easily lost efficacy. If the length of expansion bead is long, canThe damping, buffering effect of expansion link, telescoping cylinder and coil tension spring is had a greatly reduced quality, expansion beadThe proportion of goods damageds larger, need often to change packing ring. These three grades of buffer damping mechanisms can be applied to manyIndividual aspect, as the wheel damping of bicycle, motorcycle, damping of process equipment workbench etc.
Below in conjunction with brief description of the drawings and detailed description of the invention, the utility model is described in further detail.
