AI Technical Summary

Technical Problem

In existing photographic equipment, the QD connector is prone to mis-locking due to accidental single-button touch, causing the camera to fall off the camera strap, resulting in equipment damage and high repair costs.

Method used

Design a connector to prevent accidental disassembly. It adopts an independent main unlocking mechanism and a safety lock mechanism to form a double-key unlocking mechanism. The movement is prevented from moving the inner shaft in the normal locked state by the movement limiting structure. Unlocking can only be achieved by allowing the inner shaft to move after the release mechanism is pressed.

Benefits of technology

It effectively avoids mis-locking of connectors, improves the connection security and stability of photographic equipment, reduces the risk of equipment damage and maintenance costs, and maintains ease of operation.

Abstract

The utility model discloses an anti-mistaken touch dismounting joint and a joint assembly, the anti-mistaken touch dismounting joint is used for connecting and locking photographic equipment, the anti-mistaken touch dismounting joint comprises a housing, a sliding cavity is arranged in the housing, one end of the housing along the axial direction is provided with a plugging part plugged with the photographic equipment, and the side wall of the plugging part is provided with a spring bolt structure in a penetrating manner; the inner shaft is arranged in the sliding cavity in a sliding mode, and the inner shaft can abut against or loosen the spring bolt structure through movement; the main unlocking mechanism is movably arranged on the side wall of the shell in a penetrating mode and used for extruding the inner shaft to move so as to loosen the spring bolt structure; the safety lock mechanism comprises an unlocking mechanism which is movably arranged on the side wall of the shell in a penetrating mode, and the unlocking mechanism and the main unlocking mechanism are arranged in a spaced mode. The limiting structure is configured to prevent the inner shaft from moving when not driven by the delimiting mechanism; when driven by the delimiting mechanism, the inner shaft is allowed to move. According to the mistaken touch prevention disassembly connector, the independent main unlocking mechanism is arranged, the safety lock mechanism is arranged, a double-key unlocking mechanism is formed, and the mistaken unlocking risk is reduced.
