2results about How to "Achieve length" patented technology

This utility model relates to the field of landscape water decoration technology, and in particular to a non-splashing rainwater chain drainer, including a water guide cup, a support member at the top of the water guide cup, and a threaded rod at the top of the support member. The threaded rod passes through the support member and extends into the water guide cup, and is rotatably connected to the support member. The top of the threaded rod is threaded with a horn nut and a fixing nut, respectively. The horn nut is located at the top of the support member, and the fixing nut is located at the bottom of the support member. By using the threaded rod, horn nut, fixing nut, spherical structure, and connecting nut in combination, the distance between the drainer and the rainwater chain can be easily adjusted to reduce water splashing outward due to excessive distance between them and the influence of wind. The connecting nut is used to connect the rainwater chain structure, and its internal structure is threaded. The spherical structure is used to fix the connecting nut on the threaded rod. By adjusting the horn nut, the length of the entire rainwater chain can be adjusted, thereby achieving overall fixation of the rainwater chain.

The application discloses a roller shutter type filter and a use method, and relates to the technical field of air filtration. The filter comprises a rack, upper and lower winding boxes, upper and lower winding shafts, two driving modules, a flexible belt wound around the upper winding shaft and a filter core clamp head. The lower winding shaft is detachably arranged in the lower winding box. An electromagnetic clutch is arranged between each driving module and the corresponding winding shaft. When new material is added, the filter core clamp head clamps a filter core material head, and the upper winding shaft winds the flexible belt to pull the filter material upward to form a roll. When the material is replaced, the lower winding shaft actively winds, and the upper winding shaft follows to unwind. When the clutch is separated, the rigid connection between the driven end and the driving module is cut off, the unwinding resistance is greatly reduced, and the filter material is prevented from being deformed due to excessive tension. When the clutch is attracted, the inertia of the unwinding end is inhibited by using the structural resistance of the driving module, and the filter material is prevented from being excessively released to cause relaxation. The application concentrates all the material replacement operations at a low place, eliminates the climbing operation, avoids secondary dust pollution, and realizes stable and reliable material replacement.
