The component is composed of multiple key parts, and each part cooperates closely to achieve the stable suspension of the bell jar. Publication No. CN217972266U discloses a bell jar hanger, including a hood for placing the anode guide rod and a circular chain for lifting the hood. A mounting frame is fixed on the top of the hood, and one end of the circular chain is fixedly connected to the mounting frame; a vertical pressure shaft is movably installed on the mounting frame, and the pressure shaft passes through the mounting frame and then extends into the hood; a pressure plate is fixed on the top of the pressure shaft, and a symmetrically arranged connecting rod 2 is fixed on the bottom of the pressure shaft, and the connecting rod 2 passes through the hood; a clamping block for locking the anode guide rod is symmetrically installed on the hood, and the clamping block is located below the connecting rod 2 and corresponds to the position of the connecting rod 2. It is connected to connecting rod one; a pull rod is also fixed on the clamping block; this solution increases the force-bearing area of ​​the pressure shaft by arranging a pressure plate, so that the movement of the pressure shaft is more stable; by arranging a pull rod on the clamping block, when the anode guide rod is stuck in the cover body, it can be manually opened by the staff; by arranging a counterweight block 15, the overall weight of the cover body is increased, and it is more stable during the lifting process. Although the product moves the center of gravity downward when suspended to maintain stability, it is inconvenient when the connection components need to be disassembled and maintained. Workers need to use tools or even multiple workers need to cooperate in disassembly, which reduces the convenience of disassembly and assembly, and has poor practicality, and needs to be improved.
