The present disclosure relates to a dispensing drum for a sheet material dispenser, the dispensing drum comprising first and second part-cylindrical drum members that are coupled together to form a drum body defining a central axis. The first and second drum members are coupled together by an end piece located adjacent to a first end of the drum body. The end piece comprises a first mounting formation that is engaged with a corresponding first mounting formation provided at the first end of the drum body to form a first coupling, and a second mounting formation that is engaged with a corresponding second mounting formation provided at the first end of the drum body to form a second coupling. The first coupling is configured to be formed by bringing the first mounting formations together in a first direction aligned with the central axis of the drum body, and the second coupling is configured to be formed by bringing the second mounting formations together in a second direction perpendicular to the central axis of the drum body.

The utility model relates to the technical field of part spraying, and discloses a charging plug anti-misplug guide assembly, which comprises an insulating shell and a joint, the inside of the insulating shell is fixedly connected with a telescopic column I, the outer wall of the telescopic column I is sleeved with a compression spring I, the other end of the telescopic column I is fixedly connected with a fixed block, and the fixed block is fixedly connected with the joint. A plurality of fixing rods are fixedly connected to the top of the fixing block, the outer wall of the fixing block is slidably connected to the inner wall of the insulating shell, a plurality of pins are fixedly connected to the outer wall of the insulating shell, and a clamping assembly is arranged in the insulating shell. According to the utility model, when the plug is connected into a normal socket, the traction block is pulled to drive the extension tube to extrude the spring II to retract into the sleeve, because the socket has no clamping groove, when the plug approaches, the plane of the socket contacts the fixing rod, the fixing block extrudes the spring I to slide and extrudes the limiting column II to compress the spring II, and finally the spring II pushes the limiting column II to be clamped into the fixing block groove to realize stable connection.

This invention provides a method for constructing a cross-cluster active-active architecture, a data writing method, a device, a medium, and a product, applied in the field of cloud platform technology. The method uses a storage performance development kit (SDK) to register virtualized logical units created for two clusters as block device abstractions (BADs). Then, it establishes connections between the internal systems of two nodes in different clusters. Finally, it constructs redundant mirrored BADs for the two connected nodes in different BADs and sets them on the corresponding nodes. This allows data to be written to the corresponding BAD based on the data sent by the client and the default data writing path. Therefore, this invention, by leveraging the SSD, ensures compatibility and adaptation between heterogeneous storage resources and user-space input / output stacks. The construction of redundant mirrored BADs ensures real-time data consistency across clusters, achieving standardized, high-performance, and highly reliable cross-cluster active-active operation.

The utility model relates to interface technical field discloses a side -entry type fool -proof shielding interface, include: main part, the main part includes the connector socket of setting in the main part one end and sets up on the fool -proof slot of connector socket, wherein, the fool -proof slot is fixed with the locating lug in, and the locating lug is set up with the through slot, and the through slot is fixed with rubber plug. The utility model designs the fool -proof slot, and the stable connection is carried out with the plug, prevents the error of plug -in, avoids the situation of appearance to plug -in, protects the use safety of equipment, simultaneously, the interface plug -in process, the firm safety of connection, is not easy to loosen, after the interface and the plug connection, appear to be unable to pull out, through the dismantling rubber plug, the pull -out of plug is convenient, the interface modularization design, matches and installs on the circuit board, and the scope of application is wide.

The invention discloses a body-building chest expander adaptive to multi-part exercise and a using method thereof.The body-building chest expander comprises an elastic tension assembly, two fixed end assemblies are detachably connected to the two ends of the elastic tension assembly respectively, and a tension fine adjustment assembly is assembled in the fixed end assemblies; the fixing end assemblies are used for adjusting the assembling positions of the ends of the elastic tension assemblies in the fixing end assemblies, then fine adjustment of elastic tension is achieved, the outer end of each fixing end assembly is provided with the corresponding holding ring assembly, and the multi-part exercise assemblies are detachably assembled on the fixing end assemblies. Through detachable switching of the multi-part exercise assembly, the exercise requirements of the upper limbs, the lower limbs, the shoulders and the back and other parts are met, the tension fine adjustment assembly is arranged, the compression amount of a fine adjustment spring is adjusted through sliding of a connecting base, accurate fine adjustment of elastic tension is achieved, and the exercise effect is good. And requirements of different exercise intensities and different exercisers can be met.

This utility model relates to the field of gas pipeline technology. In particular, it relates to a leak-proof connection structure for urban gas pipelines, including a base pipeline. One end of the pipeline is fixedly installed with a flange ring one and a flange ring two. The surface of flange ring two has an installation port for connecting flange ring one and flange ring two. A locking block is fixedly installed on the surface of flange ring one. The protruding end of the locking block has a telescopic opening. A telescopic groove is formed on one side of the inside of the locking block. A locking assembly for locking flange ring one and flange ring two is installed inside the telescopic groove. Through the cooperation of the locking block on the surface of flange ring one with the locking assembly and limiting assembly in the telescopic groove, an efficient, stable, and safe connection is achieved. The tight cooperation between the locking block and the locking assembly significantly improves the connection stability, effectively preventing loosening or detachment, thereby greatly enhancing the leak-proof performance.
