An integrated sealed handwheel

Abstract

The invention discloses an integrated sealed hand wheel and a manufacturing method thereof. The integrated sealed hand wheel comprises a positioning ring, a counterweight and a body, wherein the positioning ring is formed in an injection molding mode the first time. The counterweight is installed on the positioning ring, then the positioning ring is put into a mold, and injection molding is carried out the second time, so that the counterweight and he positioning ring are fused and connected into the body as a whole. In this way, the counterweight is wrapped in a sealed containing cavity formed after fused connection of the positioning ring and the body, thereby being isolated from the external steam and air. According to the integrated sealed hand wheel and the manufacturing method thereof, the counterweight is effectively prevented from being rusted, integrated forming is adopted, a subsequent adaptation process is omitted, the production efficiency is improved, the strength is improved, and the service life of the integrated sealed hand wheel is longer.

Description

technical field [0001] The invention relates to the sanitary ware industry, in particular to the field of handwheels. Background technique [0002] In today's increasingly scarce resources, the use of plastics instead of alloys to manufacture handwheels or handles has been accepted by the majority of manufacturers and consumers. Due to the light texture of the plastic handwheel and handle, the feel is not as good as the handwheel and handle made of alloy. People often add iron weights to the handwheel to increase the texture and make it feel close to the alloy handwheel and handle. handle. The traditional method of adding a counterweight block is generally to insert the counterweight block into the main body and then insert the fixed block, and fix the counterweight block in the main body through the interference fit between the fixed block and the main body. The fixed block is generally stamped from a galvanized sheet, or made of a thin-walled plastic part. When there is ...

AI Technical Summary

Problems solved by technology

The fixed block is generally stamped from galvanized sheet, or made of thin-walled plastic parts. When the interference fit between the bodies, the deformation at each matching point is not consistent, and it cannot be completely sealed with the body. The wheel handles are used in high humidity working conditions. The counterweight is easy to rust and form rust water in long-term contact with the outside air and humid water vapor. The rust water seeps from the bottom of the hand wheel and affects the appearance of the angle valve. It needs to be wiped frequently. It brings a lot of inconvenience, and the rusty water may seep into the waterway of the angle valve and flow out along the angle valve, which is not conducive to people's health; secondly, the parts of the handwheel need to be installed manually after production, the production efficiency is low, and the assembly quality is uneven. together
