Embodiment Construction

[0029] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1 to Figure 4 As shown, a flexible tripping structure of the present invention includes a manual operating mechanism, an electric operating mechanism, a closing semi-axis mechanism and an interlocking mechanism. The closing half-shaft mechanism includes a closing half-shaft 10 and a flexible trip plate 8 installed on the closing half-shaft 10 , and the closing half-shaft 10 is also connected with a closing half-shaft rotation reset device.

[0031] In this embodiment, the flexible tripping plate 8 is made of 1mm 65Mn spring steel plate, which can drive the closing half shaft 10 before elastic deformation, so as to reliably close. After closing and interlocking, the push plate is driven again, and the flexible trip plate deforms elastically, effectively realizing the closing and interlocking function.

Abstract

The invention discloses a flexible tripping structure, which includes a manual operating mechanism, an electric operating mechanism and a closing half shaft mechanism. The closing half shaft mechanism includes a closing half shaft and a flexible trip plate installed on the closing half shaft. The operating mechanism is located on one side of the closing half shaft, which is mainly composed of a handle, a splitting shaft and a push plate. The handle is installed on the splitting shaft, and a pushing plate protruding outward is connected to the splitting shaft; Located on the other side of the closing semi-axis, it is mainly composed of a push rod and a pushing device that pushes the push rod out; the flexible trip plate includes a manual closing action part that protrudes radially to one side of the push plate and a radially The electric closing action part protruding to the side of the push rod. The invention not only ensures the effective stroke, but also the overall force is even and does not cause twisting to affect the action, etc., and effectively solves the problems of short life, unreliability, and breakage in the process of driving opening, closing and tripping.

Description

technical field [0001] The invention relates to the technical field of electrical switchgear, in particular to a flexible tripping structure. Background technique [0002] The flexible tripping structure of manual opening and closing in the power switch mechanism often adopts a torsion spring structure. The torsion spring structure is prone to overall torsion due to one-sided force, and the action is unreliable. At the same time, the number of actions increases, and it is easy to be fatigued and deformed, resulting in driving distance. Insufficient, resulting in failure to close, affecting switch performance. At the same time, the original mechanism of the electric trip baffle adopts a baffle with a screw rod, which is easy to break at the threaded buckle after frequent movements. [0003] For example, the invention patent of the notification number CN106373822B provides a circuit breaker spring operating mechanism, including a mechanism box, a camshaft is arranged in the m...
