密封结构铰链

By designing a sealed hinge structure, the upper and lower limits are used to restrict the rotation range of the transition section and the moving end. Combined with ball bearings and guide grooves, a tight fit between the sealing box lid and the sealing box is achieved, solving the problem of poor sealing and improving sealing performance and stability.

AI Technical Summary

Technical Problem

In existing sealing structures, ordinary hinges cannot adjust the gap between the sealing box and the lid, resulting in poor sealing, material leakage, and the entry of external substances.

Method used

Design a sealing structure hinge including a fixed end, a movable end, a transition section, an upper limit position, a lower limit position, and a connecting piece. The upper and lower limits limit the rotation range of the transition section and the movable end. Combined with ball bearings and guide grooves, it can achieve precise adjustment of the gap between the sealing box cover and the sealing box.

Benefits of technology

It effectively prevents material leakage from the sealed structure, prevents external air, dust and moisture from entering, improves sealing reliability, and enhances the stability of the hinge structure.
