Description

Technical Field

[0001] The utility model belongs to the technical field of pin structures, and more specifically, particularly relates to a wear-resistant pin with a reinforcement structure at the node. Background Art

[0002] A pin is a type of standardized fastener that can be used for static fixed connection or relative movement with the connected parts. It is mainly used at the hinge of two parts to form a hinge connection. The pin is usually locked with an open pin, which is reliable in work and convenient for disassembly. The function of the pin is to position and fasten components. It has two types: cylindrical and conical. The installation of the pin generally adopts two methods: press-fitting method or knocking in with soft metal.

[0003] Based on the above, at present, the strength of most pin nodes is relatively low. After long-term use of the pin, the welding at the pin node is prone to breakage and falling off. At the same time, most pins are only provided with a single support column. When the pin rotates due to the outside force, the support column is prone to wear, affecting the subsequent disassembly and assembly of the pin. Summary of the Utility Model
