Locking base and bolt corrosion prevention protecting device with locking base

The invention relates to a locking base and a bolt corrosion prevention protecting device with the locking base. The locking base is of a hollow structure; an inner hole of the locking base is consistent with the outer surface of the lower part of a corresponding bolt corrosion prevention cover in shape, and is tightly matched with the same; the bottom surface of the locking base is tightly contacted with a bolt mounting surface; one or more anti-falling rings matched with anti-falling ropes are formed in the outer surface of the locking base; and an annular groove for gluing is formed in thebottom surface of the locking base. The locking base can prevent falling of the bolt corrosion prevention cover to eliminate potential safety hazards of harming circuits so as to guarantee the operation safety of railways. 本发明涉及种防脱底座及带有防脱底座的螺栓防腐保护装置，其特征在于，所述防脱底座是中空结构，所述防脱底座的内孔与相对应螺栓防腐罩下部外表面形状致且紧密配合，所述防脱底座的底面与螺栓安装面紧密接触；所述防脱底座的外表面上还设置有与防掉绳配合的个或个以上的防掉环；所述防脱底座的底面上设置有用于涂胶的环形凹槽。本发明中可以防止螺栓防腐罩脱落，消除危害线路的安全隐患，保证了铁路的安全运行。
