A closet flange plug for sealing an opening of a closet flange and for being cut away by operation of a hole saw. The closet flange plug has an annular body portion for sealing the closet flange opening and a drill guide post concentrically disposed within the body portion. The drill guide post has a solid base portion of a material, such as polyvinyl chloride (PVC) thermoplastic, operative to bind in the hole saw drill bit. The annular body portion is adapted to be cut through by the hole saw. The drill guide post has an upper portion projecting above the annular body portion while the base portion projects below the annular body portion. A borehole concentrically disposed within the upper portion of the guide post has a portion sized to interfere with and be drilled into by the hole saw drill bit.

This utility model relates to the field of valve closets, and more particularly to a valve closet with a protective device. The valve closet body has valve flanges fixedly installed on both sides, and both ends of the valve closet flanges are fixedly connected to pipe flanges on the connecting pipe by bolts. A fixing cover is fixedly installed on the top of each valve closet flange, and a limiting cavity is formed at the bottom of each fixing cover. The limiting cavity is adapted to the pipe flange, and a locking plate for locking the bolts is vertically movable on each fixing cover. In this utility model, by setting a fixing cover and a vertically movable locking plate on the top of the valve closet flange, combined with the continuous downward pressure provided by a spring, the three top bolts can be constantly locked. This effectively prevents them from loosening due to vibration, improves connection stability, and achieves connection protection for the valve closet body.

The present invention provides an expandable anchor bolt system for securing a toilet to a closet flange. The system includes an anchor bolt with an expandable lower end designed to securely engage with a groove of the closet flange, and an upper end configured to accommodate fastening means. The expansion mechanism is activated by inserting an expansion pin that does not require tools and can lock to maintain the expanded state of the anchor bolt. The system further comprises a bolt cap for covering the upper end of the assembled components, offering an aesthetically pleasing finish and protection. The system is adaptable to various flange conditions, particularly suitable for installations involving damaged or compromised closet flanges. This invention simplifies the installation process while ensuring the stability and safety of the toilet installation, providing an improved method for toilet installation in both new construction and repair scenarios.
