Embodiment Construction

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

[0030] Such as Figure 1 to Figure 4 As shown, a novel 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 novel flexible tripping structure. The structure comprises a manual operating mechanism, an electric operating mechanism and a switching-on half-shaft mechanism, wherein theswitching-on half shaft mechanism comprises a switching-on half shaft and a flexible tripping plate installed on the switching-on half shaft; the manual operating mechanism is located at one side of the switching-on half shaft and is mainly composed of a handle, a switching-off and switching-on shaft and a push plate; the handle is installed on the switching-off and switching-on shaft, and the switching-off and switching-on shaft is connected with the push plate protruding outwards; the electric operating mechanism is positioned at the other side of the switching-on half shaft and mainly comprises a push rod and a push device for pushing the push rod to extend out; and the flexible tripping plate comprises a manual switching-on operation part extending to one side of the push plate along the radial direction and an electric switching-on operation part extending to one side of the push rod along the radial direction. According to the invention, the effective stroke is ensured, the overall stress is uniform, the situation that the operation is influenced by torsion and the like is avoided, and the problems of short service life, unreliability, fracture and the like in the process ofdriving switching-on and switching-off tripping are effectively solved.

Description

technical field [0001] The invention relates to the technical field of electrical switchgear, in particular to a novel 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...
