AI Technical Summary

Technical Problem

During use, traditional viscous dampers are prone to excessive gap between the damper and the connecting device, which leads to jitter during buffering, affecting the buffering effect. After use for a period of time, wear will occur at the connection, affecting performance stability and service life.

Method used

A long-life gap-free viscous damper is designed. By opening oil storage holes and connection channels on the inner wall of the concave flange, the lubricating oil is used to keep the ball head lubricated for a long time, reducing wear, and reducing connection gaps through the cooperation of the ball head, concave flange and convex flange, quickly installing and disassembling components to improve installation efficiency.

Benefits of technology

It effectively avoids wear, extends the service life of the device, reduces connection gap, improves buffering effect, and improves installation efficiency.

Abstract

The utility model relates to the field of dampers, and discloses a long-service-life gapless viscous damper which comprises a damper body, a damping rod is arranged on the left surface of the damper body, a connecting rod is fixedly connected to the left surface of the damping rod, and a ball head is fixedly connected to the left surface of the connecting rod. A lubricating assembly is arranged on the left surface of the ball head and comprises a connecting base, a concave flange is fixedly connected to the right surface of the connecting base, a round pipe penetrates through and is fixedly connected to the upper surface of the concave flange, a one-way valve is arranged in the middle section of the round pipe, and a quick release assembly is arranged on the right surface of the concave flange. Due to the fact that the oil storage hole is formed in the inner wall of the concave flange, when the damper works, lubricating oil in the oil storage hole can keep the ball head lubricated for a long time, abrasion is avoided, the service life of the device is prolonged, the lubricating oil can be supplemented in time from the round pipe, and practicability of the device is guaranteed.
