The invention relates to the technical field of anti-pirate grids, and discloses a folding type anti-pirate grid design which comprises a rear-end grid, a rear-end shaft seat is arranged on the upper surface of the rear-end grid, a rear-end rotating shaft is rotationally connected into the rear-end shaft seat, a connecting seat is connected to the surface of the rear-end rotating shaft in a sleeving mode, and the rear-end rotating shaft is connected with the connecting seat in a sleeving mode. And a front-end rotating shaft, a front-end grating, a limiting seat and a fixing seat are inserted into the connecting seat. Compared with the prior art, the invention provides a folding type pirate-preventing grille design, and the situation that under the condition that no upper-layer inclined ladder is used for hanging, the storage gravity center of the pirate-preventing grille is too high, and consequently the ship vibrates obviously under the normal working condition is avoided; the overall length is too long, profile deformation can be caused by overall manufacturing, correction work is added, self-locking operation is completed through ejection of butt joint bolts in a fixing bolt set after movement is conducted through a sliding rail, and after a hand crank is rotated, a spring is pushed to eject a front end grille, and a single person in a ship rapidly completes closing operation of multiple folding type anti-pirate grilles.

    本发明涉及防海盗格栅技术领域,且公开了一种折叠型式的防海盗格栅设计,包括后端格栅,所述后端格栅的上表面设有后端轴座,所述后端轴座的内部转动连接有后端转轴,所述后端转轴的表面套接有连接座,所述连接座的内部插接有前端转轴和前端格栅、限位座、固定座。与现有技术相比,本发明提供了一种折叠型式的防海盗格栅设计,具备避免在无上层斜梯挂靠的情况下,其存放的重心偏高,导致船舶正常工况下,振动明显;总体长度过长,整体制作会导致型材变形,增加矫正工作,通过滑轨进行移动后通过固定栓组内部对接栓的弹出完成自锁操作,转动手摇把后,推动弹簧将前端格栅弹出后,使船内人员单人快速的完成多个折叠形式防海盗格栅的闭合操作。
