The utility model relates to an anti-theft mechanism of Guli wellhead cover, which comprises a vertical bolt at the edge of the cover body and a transverse lock block at the lower end of the cover body through which the bolt passes. The feature of the mechanism is that a conical through hole is left on the inner cover body of the bolt, and a lock block hole coinciding with the axis of the conical through hole is left on the inner end of the lock block, and a conical pin is installed in the conical through hole, and the lower end of the conical pin is placed in the lock block hole. It solves the problem of metal cap of Guli well in underground pipeline, locking by simple bolts and lock blocks, and unsafe cap body. It is widely used in various underground pipeline inspection wells, such as sewage pipe.
【技术实现步骤摘要】
古力井口盖防盗机构
本专利技术涉及排污管道等检查维修设施领域，具体地说是一种污水管等地下管道检查井口盖保护装置。
技术介绍
目前地下管道古力井的金属制口盖，大多是在盖体侧边留有螺栓孔，在将盖体安装到外座上后，再在螺栓孔内装上螺栓，靠螺栓下端的锁块卡住外座围沿，锁紧螺栓便可锁定盖体，这种结构简单，但很不安全，只要用专用扳手就可轻易取下盖体。
技术实现思路
本专利技术为解决地下管道古力井的金属口盖，靠简单的螺栓、锁块锁定盖体不安全的问题，提供一种加装锥销的古力井口盖防盗机构。本专利技术的技术方案是，一种古力井口盖防盗机构，包括在盖体边沿处有竖向的螺栓，螺栓穿过盖体下端有横向的锁块，其特殊之处是，在螺栓内侧的盖体上留有锥形通孔，锁块的内端上留有与锥形通孔轴线重合的锁块小孔，锥形通孔内装有锥销，锥销的下端置于锁块小孔内。使用时，先将盖体装到外座围沿上，使锁块的外端卡到外座围沿的下面，锁紧螺栓，再将锥销装入锥形通孔，使锥销的下端沉入锁块小孔内即可。本专利技术的技术效果是，采用上述技术方案，可以实现一种安全可靠的古力井口盖防盗装置。它通过防盗锥销下端沉入锁块小孔阻止锁块转动，使锁...
