The utility model discloses a robot connecting line protecting and reinforcing device, which relates to the technical field of robot connecting lines, comprises a fixed base, a connecting bent piece and an outer protecting tube, and is characterized in that a first rotating bearing is fixedly connected to the outer side of one end of the connecting bent piece, and a base threaded connecting piece is rotatably connected to the outer side of the first rotating bearing; the base threaded connecting piece and the fixed base are in threaded connection with each other, second rotating bearings are fixedly connected to the outer sides of the two ends of the outer protection pipe correspondingly, and threaded rings are rotationally connected to the outer sides of the two second rotating bearings correspondingly. The fixing bases are installed at the two ends of a robot outgoing line in a threaded mode, then one ends of the two sets of connecting bent pieces are installed on the two sets of base threaded connecting pieces respectively and connected to the fixing bases in a threaded mode, and a robot connecting line penetrates through the inner threading protection pipe on the inner side of the outer protection pipe.

Embodiments of the present disclosure disclose an adaptive memory conversion method and device for a distributed file system. A specific implementation of the method comprises: dividing a metadata set in a target directory to obtain a metadata subset group; setting a corresponding memory data structure form for each metadata subset; determining a target metadata subset; executing a corresponding access processing flow on the target metadata subset to obtain and output a final access result; obtaining access feature sets and system resource states of each metadata subset in the metadata subset group in real time to obtain a directory index set; determining memory data structure form conversion instructions corresponding to metadata subsets to be converted in the metadata subset group to obtain a conversion instruction set and a to-be-converted metadata subset group; and performing data reconstruction on the to-be-converted metadata subset group to obtain a converted metadata subset group. The implementation can improve memory utilization, reduce redundant memory occupation, and reduce unnecessary data access overhead.

The utility model relates to a magnetic attraction battery technical field, and disclose a kind of magnetic attraction battery pack power supply structure, comprising: main body connection structure, set in the bottom of conference machine, including battery installation site, multiple first permanent magnets and power supply contact point, wherein first permanent magnet forms fixed adsorption point, and power supply contact point is metal spring contact point, for providing power interface;Magnetic attraction type battery pack, including shell, multiple second permanent magnets and elastic conductive sheet, wherein second permanent magnet is correspondingly set with the first permanent magnet of main body connection structure. The utility model, magnetic attraction type battery pack is connected and separated with the quick connection of conference machine main body by magnetic force adsorption, and battery pack can be replaced in extremely short time by single hand operation, without accurate alignment and exerting larger mechanical force, effectively solve the problem of interruption due to insufficient power in long time meeting, realize seamless endurance switching in meeting process, simultaneously avoid cable bondage.
