Abstract
The utility model relates to a damper, which comprises a cylinder body, a plug, a sealing guide sleeve, a spring, a movable isolating plug, a sealing piece, hydraulic fluid, a piston provided with a damping channel, a piston rod and a connecting piece. The damper is characterized in that the plug is arranged at one end of the cylinder body; the sealing guide sleeve is arranged at the other end of the cylinder body; a spring air cavity formed by the spring, the movable isolating plug and the sealing piece is arranged on one side in the inner chamber of the cylinder body; a hydraulic fluid cavity filled with the hydraulic fluid is arranged on the other side of the inner chamber; the movable piston provided with the damping channel is arranged in the hydraulic fluid cavity; and the piston rod passes through the sealing guide sleeve, wherein one end of the piston rod is connected with the movable piston provided with the damping channel, and the other end is connected with the connecting piece. The utility model has the benefits that the problems of mixing of oil and gas, unsteady operation and noise making after long-term use do not exist, and has the advantages of simple and reasonable structure, impact resistance, good buffering effect, long service life and the like.
Description
Technical field
The utility model relates to a kind of damper, is a kind of damper that is used on the furniture specifically.
Background technique
The present normal a kind of damper that uses on the top-grade furniture, its structure are that the end at cylinder body is provided with a shutoff, at the other end of cylinder body a sealing guide sleeve are set; The mobile piston and the energy-absorbing sponges cover of a band damp channel are set in being full of the cylinder body chamber of hydraulic fluid, and a piston rod passes the sealing guide sleeve, an end connecting band damp channel mobile piston, the other end connecting piece.The damper of this structure, its working principle is: when the piston rod of band damp channel is made back and forth movement in chamber, spatial volume in the chamber changes, hydraulic fluid, absorbs because of piston rod by air compression in the energy-absorbing sponges cover and to enter the volume that cylinder body has more to opposite side from mobile piston one effluent of band damp channel.Exist deficiency in using for a long time, the air in the energy-absorbing sponges cover is very easily gone in the hydraulic fluid, causes the oil gas mixing, moves steady and sends sound.
Summary of the invention
The technical problems to be solved in the utility model is to provide the damper of a kind of simple and reasonable, shock-resistant, good buffer effect, long service life, to overcome deficiency of the prior art.
The technical solution adopted in the utility model is: a kind of damper, comprise cylinder body, shutoff, sealing guide sleeve, spring, move and isolate stifled, Sealing, hydraulic fluid, band damp channel piston, piston rod and link, described shutoff comprises end cap, seal ring, baffle ring, described sealing guide sleeve comprises guiding end cap, Sealing, baffle ring, described band damp channel piston comprises band oil-through hole chock plug and stuffing box gland, it is characterized in that: the end at cylinder body is provided with a shutoff, at the other end of cylinder body a sealing guide sleeve is set; Side setting in inner chamber of cylinder block by spring, move to isolate spring air cavity stifled, that Sealing constitutes, the opposite side inner chamber is full of hydraulic fluid and constitutes hydraulic fluid chambers; A band damp channel mobile piston is set in hydraulic fluid chambers, passes the sealing guide sleeve by a piston rod, an end connecting band damp channel mobile piston, the other end connects link.
The beneficial effects of the utility model are: be with the damper of energy-absorbing sponges cover to compare with normal use at present, the utility model can not take place in long-term the use that oil gas mixes, operation not steadily and send the problem of sound, but also have advantages such as simple and reasonable, shock-resistant, good buffer effect, long service life.
