Description

Technical Field

[0001] The utility model relates to the technical field of vacuum coating accessories, in particular to a counterweight ring mechanism. Background Art

[0002] Vacuum coating involves heating a metal or non-metallic material under high vacuum conditions, causing it to evaporate and condense onto the surface of the object (metal, semiconductor, or insulator), forming a thin film. Examples include vacuum aluminum and vacuum chromium coating. It's well known that coating certain materials with a thin film can impart numerous new and advantageous physical and chemical properties. Vacuum coating requires the use of counterweight rings to maintain the weight of the coated product.

[0003] In the prior art, a manual glass coated wiper with application number 201820441600.5 includes a receiving plate seat, a wiper blade, a handle and silicone. Silicone is embedded inside the wiper blade and the silicone is pluggable and removable. The handle is connected to the receiving plate seat by snap-fitting, and the wiper blade is fixedly mounted on the receiving plate seat. A counterweight block is provided at the rear end of the handle, and the counterweight block is fixedly mounted in the handle. A steel ball is provided on the side of the handle close to the counterweight block. This manual glass coating wiper is equipped with silicone. When the silicone contacts the glass, a coating and a nano-film are produced, which can effectively make rainwater form water droplets, avoiding the noise problem caused by friction, so that no rain marks are formed on the glass. The coating produced by the silicone on the wiper rubs against the glass, releasing unique lotus leaf water-draining ions. When rainwater hits the lotus leaf water-draining glass, the rainwater gathers into water droplets and slides down smoothly, effectively brushing off rainwater and dust on the glass surface. However, it is not convenient to install and fix the counterweight ring along the radial direction, and the installation stability is low, making it inconvenient to disassemble and assemble.
