Description

External buffering hydraulic hinge Technical Field The utility model belongs to the technical field of hinges, and particularly relates to an external buffer hydraulic hinge. Background The hinge is a common mechanical connection member in opening and closing devices such as doors and windows, and has a function of enabling smooth opening and closing of a door body or a window body. As the frequency of use increases, the structural and performance requirements of the hinge also gradually increase. Conventional hinge structures generally rely on friction and elastic elements of the hinge components to control the opening and closing speed of the door body, however, these conventional designs often have some drawbacks, especially during long-term use, which can easily lead to wear of the individual components, thereby affecting cushioning performance and even causing cushioning failure. In the prior art, most hydraulic buffering hinges employ built-in hydraulic systems, and the buffering function is achieved through hydraulic devices arranged inside the hinge. Although this design provides some cushioning, wear of the hydraulic components after prolonged use may result in leakage of hydraulic oil or system failure due to the close combination of the hydraulic system and the hinge structure. In addition, because the design of the built-in hydraulic structure is complex, maintenance and replacement are difficult, once a failure occurs, the whole hinge is usually required to be replaced or the complex internal structure is repaired, thereby increasing maintenance cost and maintenance difficulty. The traditional hydraulic hinge is less in consideration of replacement and maintenance of components in design, and a plurality of hinge structures cannot be used for replacing damaged buffer components independently, so that the whole hinge needs to be replaced or maintained, and the use cost and the maintenance cost are increased.
