A type of bamboo-shaped screw with a cap

ActiveCN224433069UPipe wrenchBolt cutter
A capped bamboo-joint screw includes a screw body with a set of threaded grooves and a set of unthreaded areas on its outer surface. An adapter post is connected to the left side of the screw body, and a nut is connected to the left side of the adapter post. This device utilizes the alternating distribution of threaded grooves and unthreaded areas. When adjusting the screw length, the user can use pipe wrenches or wire cutters to clamp the unthreaded area and precisely cut it off along a preset break point. The threaded grooves remain intact after cutting, not affecting subsequent threaded connections with nuts or installation components, greatly expanding the length adaptability range and reducing the need for stock specifications. Simultaneously, the Phillips head groove on the left side of the nut, in conjunction with the adapter post, ensures that torque is effectively transmitted to the threaded section when tightening the screw with tools, enhancing installation stability. Furthermore, the integrated metal cap design makes this product aesthetically pleasing and provides excellent protection.

A wire breakage protection alarm device for a stranding machine and its usage method

This invention discloses a wire breakage protection alarm device for a stranding machine and its usage method, belonging to the technical field of stranding machines. The device includes a rotating shaft, with a pay-off reel disposed outside the rotating shaft, and a second roller at the front end of the pay-off reel. This invention addresses the significant limitations of existing technologies. The detection point is typically located on a fixed path between the pay-off roller and the take-up end, rather than at the wire exit point of the rotating pay-off reel. This means that when a single filament breaks near the pay-off reel, there is no early warning. This invention, by setting a detection structure consisting of a first roller and a second roller on the rotating pay-off reel, can capture the sudden change in tension characteristics at the moment of wire breakage, achieving rapid response and accurate positioning, and effectively suppressing interference signals caused by equipment vibration or start-stop operation. It also has a preventative function of monitoring remaining wire quantity.
