Product Description

The Open Mouth Pin: An Essential Mechanical Component!

Basic Definition

Open mouth pins, often referred to in the industry as spring pins or safety pins, are indispensable mechanical components belonging to the realm of metal hardware. Crafted from top-tier steel or other elastic materials, these pins boast one or more openings, combined with remarkable elasticity.

Main Features

1. Shape and Structure: Typically cylindrical, open mouth pins feature openings at either one or both ends. This ingenious design ensures that the split pin can be effortlessly inserted into a hole and folded to secure or connect multiple components with precision.

2. Elasticity and Toughness: Renowned for their excellent elasticity and toughness, open mouth pins can endure repeated bending without succumbing to breakage or cracks, ensuring a steadfast holding force when securing components. Their design also simplifies disassembly and reconnection.

Action and Use

1. Fixed Function: The split pin's primary role is to securely fix and connect components, preventing them from moving or loosening. In bolted connections, for instance, split pins are used to secure the bolt tail hole and nut groove, effectively preventing nut loosening.

2. Wide Application: Thanks to their distinct shape and performance, open-end pins find applications across diverse sectors including machinery, automotive, aviation, maritime, furniture, and electronics. In these realms, they excel in securing, connecting, and preventing component loosening.

Specifications and Standards

1. Nominal Specifications: The range for open-end sales typically spans 0.6~20mm, allowing for specific selections based on actual requirements.

2. Standard Specifications: Manufacturing and utilizing open-end pins necessitate adherence to specific standards such as the Chinese national standard GB/T 91-2000. These guidelines meticulously detail the basic dimensions, technical stipulations, and acceptance criteria for open-end pins.

Installation and Precautions

1. Installation Method: During installation, ensure the split pin's nominal specifications align with the pin hole diameter, avoiding substitutes like wire. Insert gently using hands or pliers; refrain from using hammers that might damage the pin or hole. To open, use tools like screwdrivers, keeping the angle at 60°. If it touches the workpiece, adjust the opening accordingly.

2. Precautions: Before usage, inspect the split pin for burrs, cracks, or rust, and avoid defective pins. Confirm its correct installation and firm fixation to maximize its fixing and connecting potential.

In summary, open-end pins are vital mechanical components with an unmatched role in connections. By grasping their features, functions, specifications, and installation techniques, one can adeptly choose split pins to ensure mechanical reliability and safety.
