Description
Technical field
The present invention relates to a kind of damper, particularly instigate to be used for the suspension of roller washing machine body, eliminate the damper that shakes, prevents to creep, reduce noise; Belong to the cushion technique field.
Background technology
Roller washing machine is the international new technology of the nineties.Its artificial hand washes by rubbing with the hands, and alternative impeller-type is washed by rubbing with the hands, and is domestic very popular.The damper that uses on the roller washing machine at present is of all kinds, can not be general.But major part is to adopt a kind of plunger type to reach the damper of damping effect by frictional damping.It mainly comprises guiding damping tube, drag ring, plunger combination, and wherein the plunger combination is made up of plunger tube and joint, and joint is fixed on the plunger tube upper end, and the plunger combination is inserted in the damping tube, and drag ring is contained between damping tube and the plunger tube.Also be provided with the damping back-up ring on the damping tube, in order to drag ring retaining in the damping tube, evenly have perforate on the damping back-up ring circumference, said perforate cooperates with equally distributed projection on the damping drum outer wall, is fixed on the damping back-up ring on the damping tube.Damping back-up ring fixing more stable, but demolition and maintenance are not too convenient, dismantle down the damping back-up ring and must destroy the damping back-up ring, bring the raising on the cost to maintenance.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: a kind of damper of damping back-up ring for convenience detach is provided for the deficiency that overcomes prior art, makes things convenient for the maintaining of damper.
Technical solution of the present invention is achieved in that a kind of damper; Comprise guiding damping tube, drag ring, plunger combination; Wherein the plunger combination is made up of plunger tube and joint; Joint is fixed on the plunger tube upper end, and the plunger combination is inserted in the damping tube, and drag ring is contained between damping tube and the plunger tube; Also be provided with the damping back-up ring on the said damping tube, in order to keep off drag ring in the damping tube, damping back-up ring and damping tube screw thread are fixed; Screw thread on the said damping back-up ring is internal thread or external screw thread.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Damper of the present invention because damping back-up ring and damping tube adopt screw thread to fix, makes things convenient for the damping back-up ring to dismantle from the damping tube, the maintaining of the damper of being more convenient for like this.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Shown in accompanying drawing 1; A kind of damper of prior art; It mainly comprises guiding damping tube 1, drag ring 4, plunger combination 2, and wherein plunger combination 2 is made up of plunger tube 5 and joint 6, and joint 6 is fixed on plunger tube 5 upper ends; Plunger combination 2 is inserted in the damping tube 1, and drag ring 4 is contained between damping tube 1 and the plunger tube 5; Also be provided with damping back-up ring 3 on the damping tube 1, in order to keep off drag ring 4 in damping tube 1; Evenly have perforate 7 on the damping back-up ring circumference, said perforate cooperates with equally distributed projection 8 on the damping drum outer wall, is fixed on the damping back-up ring on the damping tube.Also have air outlet 9 on the damping tube; When plunger combination 2 slidably reciprocates in damping tube 1; Air in the damper tube 1 can pass in and out from described air outlet 9, when the roller washing machine damper is worked like this, along with flowing of the air in the damper tube 1; Friction component that both can the chilling roll washing machine vibration absorber (damping tube, drag ring, plunger combination) can reduce the movable resistance of plunger combination 2 again.
Like accompanying drawing 2,3, the roller washing machine damper shown in 4 is a preferred embodiment of the present invention; It mainly comprises guiding damping tube 10, drag ring 40, plunger combination 20; Wherein plunger combination 20 is made up of plunger tube 50 and joint 60; Joint 60 is fixed on plunger tube 50 upper ends, and plunger combination 20 is inserted in the damping tube 10, and drag ring 40 is contained between damping tube 10 and the plunger tube 50.Also be provided with damping back-up ring 30 on the damping tube 10, in order to keep off drag ring 40 in damping tube 10; Internal thread 70 is arranged on the damping back-up ring 30; The part that cooperates with damping back-up ring 30 on the said damping tube 10 is provided with corresponding external screw thread 80, through internal thread on the damping back-up ring 30 70 and being fixed on the damping back-up ring on the damping tube cooperating of external screw thread 80 on the said damping tube 10.Said damping back-up ring 30 and said damping tube 10 are fixed through threaded engagement, and damping back-up ring 30 is disassembled from said damping tube 10 easily, so that to the maintaining of roller washing machine damper; Also have air outlet 90 on the damping tube; When plunger combination 20 slidably reciprocates in damping tube 10; Air in the damper tube 10 can pass in and out from described air outlet 90, when the roller washing machine damper is worked like this, along with flowing of the air in the damper tube 10; Friction component that both can the chilling roll washing machine vibration absorber (damping tube 10, drag ring 40, plunger combination 20) can reduce the movable resistance of plunger combination 20 again.
Damping back-up ring 30 in the foregoing description also can be provided with external screw thread, and damper tube with matching then adopts internal thread simultaneously.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Damper of the present invention because damping back-up ring and damping tube adopt screw thread to fix, makes things convenient for the damping back-up ring to dismantle from the damping tube, the maintaining of the damper of being more convenient for like this.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
