Embodiment Construction

[0008] Below with reference to accompanying drawing 1, accompanying drawing 2 the present invention is described in further detail:

[0009] This embodiment is a cylinder, and the steel ball 1 is installed at the end of the steel ball seat 2 . There are small air holes 12 around the steel ball 1, and an aperture is also arranged at the center of the steel ball seat 2, and the aperture communicates with the inner cavity of the respirator 4. The end portion of the respirator 4 is tightly pressed on the top of the inner oil cylinder 5 by the steel ball seat 2 with threads. In fact steel ball 1 like this, steel ball seat 2, respirator 4, inner oil cylinder 5 are connected together, can move up and down in outer oil cylinder 11 inner chambers. Back-moving spring 3 front ends are installed between steel ball seat 2 and cover 6, and cover 6 is connected with outer oil cylinder 11 with screw thread, has compressed the first rubber sealing ring 7 that is installed in outer oil cylinde...

Abstract

The invention disclose a widely applicable breathing hydraulic damper without oil seeping and leakage, combined of steel ball, steel ball seat, reset spring, breather, inner oil cylinder, sealing cover, rubber sealing rings, breather seat, stop ring, and outer cylinder, where the steel ball is arranged at the end of the steel bass seat, there are small air holes around the steel ball, there is a small hole in the center of the steel ball base, this small hole communicates with an inner cavity of the breather; the end of the breather is tightly pressed at the top end of the inner oil cylinder by the steel ball seat through screw thread; the front end of the reset spring is installed between the steel ball seat and the sealing cover; the sealing cover is screwed with the outer oil cylinder and simultaneously presses tightly the rubber sealing rings at the upper end of the outer oil cylinder; the rubber sealing rings are installed at the lower end of the breather seat; the upper end of the breather seat is tightly connected with the breather; the stop ring is installed at the lower end of the inner oil cylinder; the outer ring of the stop ring is provided with an oil groove; the center of the lower part of the inner oil cylinder is provided with a small hole.

Description

Technical field: [0001] The invention relates to a damper which is mainly used for reducing sound when doors and drawers of furniture are closed and dampers of various structures requiring slow opening. Background technique: [0002] There are various dampers on the market at present, and the most widely used one is a damper designed by utilizing the damping force of hydraulic small holes. But all have the phenomenon of oil leakage and oil leakage. The invention improves on this situation, and can thoroughly solve the oil leakage problem of the hydraulic damper. Invention content: [0003] The purpose of the breathing hydraulic damper of the present invention is to provide a practical breathing hydraulic damper with no oil leakage and oil leakage in various specifications. [0004] In order to achieve the above object, the technical solution provided by the present invention is: it consists of a steel ball, a steel ball seat, a return spring, a respirator, an inner oil c...
