Drawer guide rail system

A guide rail system for slidably opening and closing a drawer within an enclosure is disclosed. The system comprises a mounting bracket for fixing the system to the enclosure, the mounting bracket having a fixed rail for receiving an intermediate rail capable of sliding back and forth on the fixed rail, and a pull out rail operatively attached to the drawer and capable of sliding back and forth on the intermediate rail. A resiliently compressible damping device, channel guide with sliding member and a closing device are disposed along the mounting bracket. The pull out rail has a guiding pin on its bottom surface. The sliding member is adapted to travel along the channel guide and locate an end of the damping device that can be pushed inwardly to provide damping. The closing device comprises a housing, a resilient means, and a driver pivotally mounted with the housing and operatively connected to the resilient means. The driver is pivotable between a first locked position and a second linearly moveable position, and includes an angular slot for receiving the guiding pin and an abutment projection contactable with the sliding member. During a closing action, the pull out rail is caused to slide in a drawer-closing direction. When the guiding pin reaches and engages with the angular slot, the action of the guiding pin within the angular slot causes the driver to be pivoted from its first position to its second position where the abutment projection engages with the sliding member. Thereafter, linear movement of the driver urges the sliding member to correspondingly travel along the channel guide against the resilience of the damping device, resulting in deceleration of the closing motion.

Elevator self-diagnosis and pre-diagnosis system and method based on time-frequency transformation algorithm

ActiveCN106219342ALow costRealize self-diagnosis functionElevatorsControl systemTransformation algorithm
The invention discloses an elevator self-diagnosis and pre-diagnosis system and method based on a time-frequency transformation algorithm. The elevator self-diagnosis and pre-diagnosis system comprises a sensor and an elevator control system or comprises a frequency converter and an elevator control system. The sensor is connected with the elevator control system. The frequency converter is connected with the elevator control system. The elevator control system comprises a data conversion module, a data fusion module, a judgment module, an anomaly analysis module, an anomaly / fault clearance module and an anomaly / fault information sending module. According to the elevator self-diagnosis and pre-diagnosis system and method, labor cost of a company is reduced greatly, the number of times of elevator stopping is reduced, and the experience of passengers and elevator usage efficiency are improved. Meanwhile, due to the fact that the problem of an anomaly or a fault is solved through pre-diagnosis, the technical content of products of the company is increased greatly, industrial competitiveness is promoted, and the condition that the company conducts popularization and brand establishment on the elevator products is facilitated.
