Self-locking fluid joint structure with function of uniformly distributing locking force and unlocking force

By designing a self-locking fluid connector structure and employing a combination of locking rings, return springs, and unlocking sleeves, uniform locking and unlocking of male and female plugs are achieved. This solves the problems of single-point failure, uneven locking force, and inconvenient operation in existing fluid connector structures, thereby improving the reliability and convenience of the fluid connector.

AI Technical Summary

Technical Problem

Existing fluid connector structures suffer from single-point failure risks, uneven locking force, inconvenient operation, and easy loosening after prolonged use. They are particularly difficult to meet the requirements of high reliability and convenience when used in server cooling and new energy equipment.

Method used

A self-locking fluid connector structure was designed, which adopts a combination mechanism of locking ring, return spring, unlocking sleeve and locking and unlocking roller to achieve uniform locking and unlocking of male plug and female plug. It can achieve smooth insertion and separation by hand operation and ensure uniform distribution of locking force and unlocking force.

Benefits of technology

It achieves reliable insertion and convenient separation of male and female plug mechanisms, avoids loosening and vibration caused by uneven force, improves the rationality of the structure and the convenience of operation, and meets the requirements of high reliability and convenience.

Abstract

The utility model discloses a self-locking fluid connector structure with a function of uniformly distributing locking force and unlocking force, and belongs to the technical field of fluid pipeline connecting pieces. Which comprises a male plug mechanism, a female plug mechanism, a male and female plug locking and unlocking mechanism and a fluid pipeline connector, and is characterized in that the male and female plug locking and unlocking mechanism comprises a lock ring, a reset spring, an unlocking sliding sleeve, an unlocking sliding sleeve limiting piece and a set of locking and unlocking pin rollers, the lock ring is arranged on the female plug mechanism, the reset spring is arranged outside the female plug mechanism in a sleeving mode, and the unlocking sliding sleeve limiting piece is arranged on the unlocking sliding sleeve limiting piece. The unlocking sliding sleeve is arranged outside the female plug mechanism through the unlocking sliding sleeve cavity, the left end of the unlocking sliding sleeve cavity is provided with an unlocking sliding sleeve left-right displacement stroke limiting rib, the unlocking sliding sleeve limiting piece is embedded in the female plug mechanism, and the number of the locking and unlocking pin rollers in one set is three. The method has the advantages that the operation balance and convenience are embodied; the problems of looseness, vibration and deflection in a locking state due to inconsistent stress and loss of rapidness and convenience in unlocking are avoided; and the rationality of the structure is well reflected.
