ABOUT QUICK RELEASE PINS YOU SHOULD TO KNOW  

Quick Release Pins

CHAPTER 1: QUICK RELEASE PINS, WHAT ARE QUICK RELEASE PINS?

Quick Release Pins also called as detent pins are hand operated and non-threaded cylindrical fasteners or tools that are quick and easy to operate. These pins are inserted into one or more holes for fixing a component’s position join components as well as keep the alignment between them in the assemblies that need frequent adjustment.

It is usually used for holding shear loads on plated steel and stainless steel apparatuses. This tool has different classifications. Typically, the quick release pins are used for fast assembling and disassembling. It often uses a method to offer a locking- action. It utilized a clearance-fit into the holes and was classified into two types:

Positive-locking pins

The positive-locking quick release pin comes with a locking action that is independent of the removing and insertion forces. Its main suite applications such as shear-load ones can have some loading tension that is tolerated without the need of distressing the function of the pin. The positive locking quick release pins have 3 classifications.

The positive locking pins are push-button devices that incorporate a solid stainless-steel spindle. It also has necked down waist area. On the at-rest position, the main diameter of the spindle can secure the ball on its extended position.

As the push button is activated, the spindle’s waist area can move under the balls. It allows the ball to retract inside of the shank. It enables the pins to be strong in tension. Example of this is when a 1/ 2” 17-4, 2 ball pin is rated at 1,160 pounds of pull out strength.

  • Double-acting pins – these types of quick release pin are a modification of single-action types and have a bidirectional, spring-located plunger. The movement of its plunger in different directions release the locking balls.
  • Heavy-duty cotter pins– this quick release pin uses a forged, high- carbon steel body for replacing the conventional split-cotter construction. It has a locking action that is offered by a tempered-steel snap ring that is mounted on the head of the pin.
  • Single-acting pins– comes with a locking action that is controlled by a plunger-actuated locking mechanism. In the lock position, its locking element projects beyond the pink shank surface to offer a positive lock. As the plunger was moved through lever assembly or button on one end of the pin, its locking element retracts. Moreover, the release mechanisms and head styles were made for these pins.

Push-pull pins

The push-pull quick release pins are usually crafted from the solid shank or hollow with a ball, locking lug as well as a button that is backed-up through a resilient core, plug or spring. These type of pins are 0.002 to 0.004 inches undersized in order to fit different hole-drilled to the normal diameter sizes.

The main use of the push-pull quick release pins is to fastening up the parts under a shear loading. It has a locking method that is especially made in such a manner to give safe retention from accidental disassembly. The load direction in this pin must be at right angles to the shank of the pin. Meanwhile, this type of quick release pin is not advisable to use on huge loads.

Aside from the types mentioned above, quick release pins can also be classified by its handle or head type. These types are the following:

  • T-Handle Quick Release Pins
