Abstract
The present invention discloses a respiration type hydraulic damper without oil seepage and oil leakage, which can be widely used. The present invention is formed by combining a steel ball, a steel ball seat, a offsetting spring reset spring, an inner oil cylinder, a sealing cover, a rubber sealing ring, a rubber sealing ring, a respirator seat, a retainer ring and an outer oil cylinder, wherein the steel ball is arranged on the end of the steel ball seat, and the circumference of the steel ball is provided with small air holes; the center of the steel ball seat is provided with a small hole, and the small hole is communicated with an inner cavity of a respirator; the end of the respirator is tightly pressed on the top end of the inner oil cylinder by screw threads through the steel ball; the front end of the offsetting spring is arranged between the steel ball seat and the sealing cover; the sealing cover is connected with the outer oil cylinder by screw threads, and simultaneously, the sealing cover tightly presses the rubber sealing rings arranged on the upper end of the outer oil cylinder; the rubber sealing rings are arranged on the lower ends of the respirator seat, and the upper end of the respirator seat is connected with the respirator in a tight fit mode. The retainer ring is arranged on the lower end of the inner oil cylinder, and the outer circle of the retainer ring is provided with an oil groove through which oil can flow. The center of the lower part of the inner oil cylinder is provided with a small hole.
Description
Technical field:
The present invention relates to a kind of be mainly used in furniture the door and drawer close the minimizing sound damper and various needs open the damper of structure slowly.
Background technique:
Various dampers on sale in the market, using more is to utilize hydraulic pressure small damping power and a kind of damper of designing.But all there is the phenomenon of leakage of oil and oil impregnate to take place.The present invention is directed to this situation and improve, can thoroughly solve the seepage oil problem of hydraulic damper.
Summary of the invention:
Respiration type hydraulic damper purpose of the present invention provides a kind of respiration type hydraulic damper of all practical oil-tight, leakage of oil on all size.
For achieving the above object, technological scheme provided by the invention is: it is combined by steel ball, steel ball seat, Returnning spring, resuscitation apparatus, inner cylinder, capping, first rubber seal, second rubber seal, resuscitation apparatus seat, back-up ring, outer oil cylinder, steel ball is installed in the end of steel ball seat, little pore is arranged around the steel ball, also there is an aperture at the steel ball seat center, and the share a common fate inner chamber of device of aperture communicates; The end of resuscitation apparatus is pressed on the inner cylinder top by steel ball seat with screw thread; The Returnning spring front end is installed between steel ball seat and the capping; Capping connects with outer oil cylinder with screw thread, has compressed first rubber seal that is installed in outer oil cylinder upper end simultaneously; Second rubber seal is installed in the lower end of resuscitation apparatus seat; The upper end drive fit of resuscitation apparatus seat has connected resuscitation apparatus; Back-up ring is installed in the lower end of inner cylinder; There is the oil groove that can flow through the back-up ring outer ring; The inner cylinder lower central has an aperture.
The present invention can reach oil-tight, oil tight effect by above technological scheme, and application area is wider, can be applied in the middle of the civilian military industries such as any smart instrumentation table and space flight, aviation, navigation, automobile, steamer, lathe.
Description of drawings:
Accompanying drawing 1 is structure sectional view of the present invention;
Accompanying drawing 2 is that the A of accompanying drawing 1 is to structural representation.
Embodiment:
With reference to the accompanying drawings 1,2 couples of the present invention of accompanying drawing are described in further detail:
Present embodiment is a cylindrical body, and steel ball 1 is installed in the end of steel ball seat 2.Around the steel ball 1 little pore 12 is arranged, also there is an aperture at steel ball seat 2 centers, and the share a common fate inner chamber of device 4 of aperture communicates.The end of resuscitation apparatus 4 is pressed on inner cylinder 5 tops by steel ball seat 2 usefulness screw threads.So in fact, steel ball 1, steel ball seat 2, and resuscitation apparatus 4, inner cylinder 5 has linked together, and oil cylinder 11 inner chambers move up and down outside.Returnning spring 3 front ends are installed between steel ball seat 2 and the capping 6, and capping 6 usefulness screw threads connect with outer oil cylinder 11, have compressed first rubber seal 7 that is installed in outer oil cylinder 11 upper ends simultaneously.Second rubber seal 8 is installed in the lower end of resuscitation apparatus seat 9.The upper end drive fit of resuscitation apparatus seat 9 has connected resuscitation apparatus 4.Resuscitation apparatus seat 9 can be up and down at the inner chamber of inner cylinder 5.Back-up ring 10 is installed in the lower end of inner cylinder 5, and there is the oil groove 13 that can flow through back-up ring 10 outer rings.It is keys that damping force produces that inner cylinder 5 lower central have an aperture 14, and the big damping force in hole is little, and the little damping force in hole is big.Can make the damper of various resistances as requested.
In actual applications, when damper was not hit with pressure, Returnning spring 3 was stretched out, and when being subjected to external impacts and pressure, steel ball 1 promotion steel ball seat 2 drives resuscitation apparatus 4 simultaneously and inner cylinder 5 moves down.The oil of at this moment outer oil cylinder 11 flow in the cavity of inner cylinder 5 by aperture.The oil that enters inner cylinder 5 promotes resuscitation apparatus seat 9 and moves up, and has compressed resuscitation apparatus 4, and the air of resuscitation apparatus 4 inner chambers is drained with the aperture 12 on steel ball 1 limit.When damper resetted, air entered resuscitation apparatus 4 from aperture 12 again.Because the sealing of sealing second rubber seal 8 of first rubber seal 7, hydraulic oil can only flow to outer oil cylinder 11 by aperture at inner cylinder 5, and the hydraulic oil of outer oil cylinder 11 flows to or flows out at inner cylinder 5 by aperture except flowing at the oil groove of back-up ring 10 exactly.Wherein resuscitation apparatus 4 tops be pressed on the upper end portion of inner cylinder 5 can't seepage.Capping 6 is pressed on rubber seal 7 on the interior ring of outer oil cylinder 11, and fabulous encapsulation is also arranged.Utilize the respiration of resuscitation apparatus 4 effectively to solve like this and cause oily leakage problems because of the damper action produces vacuum.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
