AI Technical Summary

Technical Problem

The existing umbrella steering knuckle mechanism requires squeezing the handle to release the locking mechanism, which results in the handle taking up a lot of space, affecting the aesthetics and reducing the strength of the ear.

Method used

Design a steering knuckle including a first connecting part, a second connecting part, a clamping part and a button assembly. The button assembly releases the clamping part from locking the protrusion, making operation more convenient and eliminating the need to provide finger accommodation space below the handle when pinching inward.

Benefits of technology

It achieves more convenient operation, a more stable and aesthetically pleasing structure, and avoids the problem of the handle taking up space and affecting the appearance.

Abstract

This utility model relates to a steering knuckle, including a first connecting part, a second connecting part, a clamping part, a first spring, and a button assembly. The clamping part includes a first clamping part and a second clamping part that cooperate with each other. A bearing is provided in the middle of the first clamping part and the second clamping part. An arc-shaped groove penetrating the width of the first clamping part and the second clamping part is provided between the bearing and the engaging part. The arc-shaped groove includes a first groove with a gradually decreasing radius and a second groove connected to the smaller radius of the first groove. When the first clamping part and the second clamping part are engaged, the two arc-shaped grooves cooperate to form a receiving hole. The button assembly includes a conical platform. When the conical platform moves inward along the axis of the receiving hole, the conical platform applies a force to both sides of the receiving hole, so that the first clamping part and the second clamping part can rotate relative to the axis of the bearing.
