The invention relates to the technical field of anti-theft fuel tanks, in particular to an anti-violent-detachment filter cartridge for fuel tank locking caps. The anti-violent-detachment filter cartridge comprises a lock cover, an upper flange, a lower flange, a filter cartridge and an arch part, the upper flange and the lower flange can be connected with a fuel tank locking cap and a fuel tank oil inlet, and an oil filter hole is formed in the side wall or the bottom wall of the filter cartridge; the arch body part comprises an upper arch body, a lower arch body and a supporting block; the surfaces of the upper arch body and the lower arch body are spherical crowns, the whole arch body is a part of a spherical shell which is intercepted by a plane and is smaller than a hemisphere, the section is parallel to the ground, and the edges are internally tangent and fixed on the side wall of the filter cartridge; the upper arch body is provided with upper oil filtering holes, the lower archbody is provided with lower oil filtering holes, and the upper oil filtering holes and the lower oil filtering holes are distributed in an up-down staggered mode. The supporting block is a column ora cylinder, the upper end of the supporting block is connected with the lower end of the upper arch body, the lower end of the supporting block is connected with the upper end of the lower arch body,and the arch body structure is of an arch-bridge-like structure formed by the upper arch body, the lower arch body and the supporting block and can effectively prevent the lock cover and the filter cartridge from being violently detached.

    本发明涉及防盗油箱技术领域,尤其涉及一种用于油箱锁盖的防暴拆滤筒,包括锁盖、上凸缘、下凸缘、滤筒、拱体部件,上、下凸缘可连接油箱锁盖和油箱进油口,所述滤筒侧壁或底壁设有滤油孔;所述拱体部件包括上拱体、下拱体和支撑块;所述上、下拱体表面为球冠,整体为一球形壳体被一平面所截取的小于半球的那一部分壳体,截面平行于地面,且边缘内切并固定在滤筒侧壁;所述上拱体设有上滤油孔,下拱体设有下滤油孔,上、下滤油孔呈上下错位分布;所述支撑块为圆柱或圆筒任意一种,支撑块上端连接上拱体下端,下端连接下拱体上端,拱体结构上、下拱体和支撑块形成的类拱桥结构,能有效地防止锁盖和滤筒被暴力拆除。
