Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.

Referring to the attached drawings 1-3 in the specification, the damper comprises an adjusting nut, an elastic cover, a shaft shell and a shaft core, wherein the shaft core is positioned in the shaft shell, blades are arranged on the side part of the shaft core, a shaft core fixing part is arranged in the shaft shell, the shaft core is fixed in the shaft shell by clamping the shaft core fixing part between the blades, and the adjusting nut is connected with the shaft shell; the elastic cover is positioned between the adjusting nut and the shaft core; through axle core mounting will separate into a plurality of damping chambeies between axle housing and the axle core, the damping intracavity has the damping oil that is used for the lubrication, damping oil in one of them damping intracavity through the elastic cover with flow into another damping chamber behind the clearance between the axle core, through adjusting nut adjusts the size in clearance. The shaft core fixing piece and the shaft shell are integrally formed.

Referring to the attached figure 2 of the specification, after the shaft core is fixed, the shaft shell rotates clockwise, the space volume of the first damping cavity is reduced, the pressure in the cavity is increased, therefore, damping oil in the first damping cavity flows to the second damping cavity through the oil way, and the slow falling time of the damper is controlled by controlling the oil passing area of the oil way and the concentration of the oil through the adjusting nut.

Referring to the attached drawing 3 of the specification, a shaft core protrusion matched with the elastic cover is arranged above the shaft core (the elastic cover just can completely cover the protrusion, but the edge of the protrusion is not pressed against the inner wall of the elastic cover, and a gap can be formed between the edge of the protrusion and the elastic cover after the elastic cover is deformed by pressure for oil passing); liquid in one damping cavity flows into the other damping cavity after passing through the gap between the elastic cover and the shaft core after the shaft core protrudes.

Referring to the description and the attached drawings 3-6, when the damper is overloaded, the pressure of the damping cavity is increased, and the periphery outside the elastic cover can expand outwards, so that the oil passing area is increased, and the pressure of the oil cavity is reduced. The size of the gap between the elastic cover and the shaft core can be adjusted by rotating the adjusting nut. The adjusting nut is connected with the shaft shell through threads, and the adjusting nut and the shaft shell can move relatively in the axial direction by rotating the adjusting nut.

Referring to the accompanying drawings 7-9 of the specification, the elastic cover is fixed below the adjusting nut, and moves along with the adjusting nut when relative movement occurs between the adjusting nut and the shaft housing. An oil storage cavity is formed among the elastic cover, the adjusting nut and the shaft core, and the oil storage cavity surrounds the central shaft of the shaft core. When the adjusting nut is rotated upwards, damping oil flows from the damping cavity to the oil storage cavity, working damping oil of the damping cavity is reduced, and the time for the damping oil to flow out of the damping cavity is reduced, so that the slow falling time of the damper is reduced; conversely, the slow-down time of the damper increases.

While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the utility model is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the utility model as defined by the appended claims.
