Abstract
The utility model relates to a silent damper which comprises a cylinder body, a plugging device, a sealed guide sleeve, compressed air bags, hydraulic fluid, a piston with a damping passage, a piston rod and a connecting piece. The silent damper is characterized in that the plugging device is arranged at one end of the cylinder body, and the sealed guide sleeve is arranged at the other end thereof; the movable piston with the damping passage is arranged in the cylinder body chamber; the piston rod penetrates the sealed guide sleeve, one end of the piston rod is connected with the movable piston with the damping passage, and the other end thereof is connected with the connecting piece so as to divide the chamber of the cylinder body into a front chamber and a back chamber; one or N compressed air bags are arranged in the front chamber or the back chamber; the hydraulic fluid is filled in the chambers; and the compressed air bags adopt sealed rubber and plastic cavities filled with gas. The utility model has the beneficial effects that the problems of oil gas mixture, unsmooth operation and noise cannot be generated during long-term use.
Description
Technical field
The utility model relates to a kind of damper, is a kind of quiet 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 quiet damper, comprise cylinder body, shutoff, sealing guide sleeve, compressing gasbag, hydraulic fluid, band damp channel piston, piston rod and link, described shutoff comprises end cap, seal ring, shelves ring, described sealing guide sleeve comprises guiding end cap, Sealing, shelves 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; A band damp channel mobile piston is set in the cylinder body chamber, and a piston rod passes the sealing guide sleeve, an end connecting band damp channel mobile piston, and the other end connects link, and the cylinder body chamber is divided into forward and backward two chambers; In preceding chamber or back chamber, one or N compressing gasbag are set, and in chamber, are full of hydraulic fluid.
Described compressing gasbag is a kind of gassiness sealing rubber and plastic cavity.
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.
