Abstract
The utility model discloses a metal air pressure type buffer damper which comprises a piston rod, a guide device, a piston, an air exhaust hole, a deep-drawing metal pipe, and a nitrile butadiene rubber sleeve, wherein the piston rod is connected with the piston; a guide sleeve is fixedly arranged on the deep-drawing metal pipe; the piston is connected and fastened with the nitrile butadiene rubber sleeve; the air exhaust hole is arranged under one side of the deep-drawing metal pipe; the nitrile butadiene rubber sleeve is fixedly arranged on the piston. The metal air pressure type buffer damper has the advantages that by adopting a metal pipe as a cylinder tube, the nitrile butadiene rubber is made into the sealing sleeve to seal the cylinder tube, the piston moves to form pressure, and the air is exhausted through an air saving hole in the cylinder tube to generate the damping buffer, so the noise in use is small; the structure is simple, the service life is long, the production cost is low, and the buffer damper is convenient for popularizing.
Description
Technical field
The utility model relates to damping buffering damper technique field, is specially a kind of metal air pressure type buffering damper.
Background technique
The case lid of modern furniture, bung, drawer is opened while closing in order to reduce noise, life-saving, is made furniture, household articles is more humane while using, and often adopts buffer damping shock-absorbing.But it is poor that present isolation damper on the market all exists shock-proof effect, the shortcoming that working life is short.For this reason, the utility model proposes a kind of shock-proof effect good, the metal air pressure type buffering damper of long service life.
Model utility content
The purpose of this utility model is to provide a kind of long service life, and the metal air pressure type buffering damper that shock-proof effect is good, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme: a kind of metal air pressure type buffering damper, comprise piston rod, guider, piston, exhaust port, pull and stretch metal tube, nitrile rubber cover, and described piston rod is connected with piston; Described guide sleeve is fixed on pull and stretch metal tube; Described piston is connected with nitrile rubber cover; Described exhaust port is positioned at a side-lower of pull and stretch metal tube; Described nitrile rubber cover is fixed on piston.
In the utility model, described piston rod can be freely movable in guider.
In the utility model, when described piston and nitrile rubber cover are engaged in the interior freely activity of cylinder barrel and are pressed into, exhaust port leaks gas at leisure, nitrile rubber cover and tube wall friction fit sealing generation resistance.When piston rod is pulled out, power is little.
Compared with prior art, the beneficial effects of the utility model are: this metal air pressure type buffering damper, adopt metal tube to do cylinder barrel, nitrile rubber is done stuffing box gland sealing cylinder barrel mineralization pressure by the exhaust port exhaust generation damping buffering of cylinder barrel, can well reach the noise producing while using very little, and simple in structure, long service life, low being convenient to of cost of production promoted.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of metal air pressure type buffering damper, comprises piston rod 1, guider 2, piston 3, exhaust port 4, pull and stretch metal tube 5, nitrile rubber cover 6, and described piston rod 1 is connected with piston 3; Described guider 2 is fixed on pull and stretch metal tube 5; Described piston 3 is connected with nitrile rubber cover 6; Described exhaust port 4 is positioned at a side-lower of pull and stretch metal tube 5; Described nitrile rubber cover 6 is fixed on pull and stretch metal tube 5 inside.
In the utility model, described piston rod 1 can be interior freely movable at guider 2.
In the utility model, when described piston 3 and nitrile rubber cover 6 are engaged in the interior freely activity of cylinder barrel and are pressed into, exhaust port leaks gas at leisure, nitrile rubber cover 6 and tube wall friction fit sealing generation resistance.When piston rod 1 is pulled out, power is little.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any reference character in claim should be considered as limiting related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme in each embodiment also can, through appropriately combined, form other mode of executions that it will be appreciated by those skilled in the art that.
