AI Technical Summary

Technical Problem

In a vibrating environment, contactors are prone to malfunction, and existing technologies are unable to effectively prevent this.

Method used

It adopts a combination structure of reaction mechanism, interlocking parts, drive assembly and fastening assembly. The interlocking parts cooperate with the limiting post and limiting hole of the connecting rod, combined with the positioning and fixing of the guide post and the protrusion, and use electromagnetic lock to achieve self-locking effect to prevent the bracket from being misoperated in the vibration environment.

Benefits of technology

It improves the stability of the contactor in vibration environments, avoids misoperation, has a simple structure, good locking effect, and is easy to operate, making it suitable for vibration environments such as ships.

Abstract

The utility model discloses a locking structure of a contactor for a ship, which comprises a counter-force mechanism and a locking mechanism, wherein the counter-force mechanism comprises a connecting rod which is connected with a bracket; the interlocking piece is matched with the connecting rod to form a first locking part and a second locking part, the interlocking piece is provided with an interlocking hole, and the first locking part and the second locking part form connection and fixation of the connecting rod and the interlocking piece; the driving assembly comprises a driving source and a spring bolt. The driving source drives the spring bolt to move. In an opening state, the spring bolt extends to the interlocking hole, and the spring bolt locks the interlocking piece; in a switching-on state, the spring bolt extends out of the interlocking hole, and the connecting rod drives the interlocking member to move. The structure is simple, the locking effect is good, misoperation of the contactor in a vibration environment is avoided, and the working stability of the contactor is improved.
