A torsional damper device

Abstract

A torsional damper device HOUSING COMPRISING DAMPER, a piston assembly and seal enclosed within the damper housing, A damper housing includes a first housing and a second housing, A fan-shaped lumen is symmetrically arranged in the first housing and the second housing, A piston assembly is disposed within the sector cavity, A piston assembly includes a piston shaft and a piston, A piston shaft extends through the first housing or the second housing to an end outside the housing and is connected with a crank connecting rod, A seal is sleeved between the piston shaft and the joint of the first housing or the second housing, The sealing member is a shaft sealing ring, the piston is sleeved into the piston rotating shaft, and the arc surface of the piston is respectively rotatably matched withthe arc surface corresponding to the sector cavity, so that the sector cavity is divided into a first cavity and a second cavity, and the first cavity and the second cavity are filled with damping fluid. The torsional damper device of the invention has the advantages of simple and reasonable structure, reliable and flexible performance, long service life, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to the field of household hinges or door brace accessories, in particular to a twistable damper device. Background technique [0002] Torsional dampers have a wide range of applications in controlling the motion of various structures, and are commonly used in furniture hinges, furniture supports, glove box doors, auxiliary handles, and the like. However, in existing furniture used in the damping hinge technology, the damper is generally arranged at the midsection of the connecting arm, that is, the cavity between the connecting arm and the adjusting base fitting. For the convenience of damper movement and function adjustment, the cavity should be sufficient The size of the main body of the hinge is large, which increases the manufacturing cost of the hinge and reduces the use space of the cabinet, and the existing damper is generally a pull-out type damper, that is, when the piston rod is pulled out, the damper only With damping ...

AI Technical Summary

Problems solved by technology

In the above-mentioned structure, both the damper and the inner shell are arranged in the middle abdomen of the outer shell, which will also cause the main body of the hinge to have a larger appearance and volume, and only when the piston rod is pulled out, the damper has a damping function, which has a problem, namely The service life of the damper will change according to its damping characteristics, because when the piston rod is pulled out, the seal in the damper housing will bear a large load and cause greater friction between the seal and the piston rod. Parts are susceptible to wear so that oil leaks
