Gating hardware knowledge

Gating hardware is a kind of important metal products for daily use in daily life, mainly in spring andspring is generally used in shopping malls, office buildings, residential buildings, exhibition halls and other public places personnel frequently, its main function is to ensure the door is open, keep thenormally open state or in time accurate close to the initial position. Generally have the function of automatic closing door closers, which can automatically close the door is open. Spring general situation is completely open, not closed automatically when not fully open, it will automatically shut down.

The core design idea is closer to achieve the control of the process of closing the door, make all kinds of function of closing process can be adjusted according to the needs of the people. Closersignificance lies not only in the door closed automatically, but also to protect the door frame and the door body, more important is the closed door has become a can not be ignored in theimplementation of modern intelligent building management section.

The key problem is the quality of door closers is leaking, because relying on its internal hydraulic system to control the process of closing the door, leakage means failure of the hydraulic system,the hydraulic system is the only standard to determine the service life of the door closer. The main reason is the oil bearing transmission due to wear cracks so that the sealing effect is reduced. So,the key bearing transmission material, heat treatment and machining quality and precision is the problem. In fact, the quality of hardware and building hardware are related to the level of industrialproduction base. A door closer is cast aluminum and cast iron two, size, number and post treatment of trachoma is blank Housing one of the key factors affecting the quality of the door closer.

The basic configuration of the spring is overhead and axis (or anchor). Is the upper part of the connecting shaft door and door frame parts, by a fixed on the door can be regulated by bolt boltshaft and a shaft sleeve is fixed on the door. The shaft can be applied to almost all of wood, steel,aluminium alloy door and glass door clamp frameless glass door.

The installation precision spring has great influence on its service life. Because the end of the service life of the spring is leaking, if the connection shaft and the spring spindle axis is not strictlyperpendicular to the ground motion will bring great torque of leaf spring, increase the wear betweenthe main shaft and the bearing, eventually leading to oil spills.
