Embodiment Construction

[0032] The manual and electric conversion knob of the circuit breaker reclosing mechanism provided by the specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] like Figure 4 and 7 As shown, the manual and electric conversion knob provided by the specific embodiment of the present invention includes a handle 1 and a main body 2, wherein,

[0034] The handle 1 is used for the operator to grasp and apply external force. The handle 1 can be a cylinder directly. In order to facilitate the user to grasp, friction patterns are formed on the outer circumference of the cylinder to increase the distance between the user and the handle 1. friction between

[0035] The cylinder 2 is rotatably installed in the reclosing mechanism. The main body 2 is set in linkage with the handle 1 to rotate under the drive of the handle 1. The outer wall 3 of the cylinder 2 is formed with a spiral extending along its axial d...

Abstract

The invention discloses a manual and electric switching knob of a breaker reclosing mechanism. The manual and electric switching knob comprises a handle (1) and a cylinder (2), the handle (1) is used for allowing an operator to grip and apply external force, the cylinder (2) is in linkage with the handle (1) to be driven by the handle (1) to rotate, and a spiral rail (4) extending along an axial direction of the cylinder (2) is formed in an outer wall (3) of the cylinder (2). The spiral rail (4) can be matched with a double-rack plate of the reclosing mechanism to realize switching among different working modes of the double-rack plate, and accordingly the reclosing mechanism can conveniently switch electric opening and closing and manual opening and closing of a breaker. Meanwhile, the switching knob is simple in structure and easy to process.

Description

technical field [0001] The invention belongs to the technical field of molded case circuit breakers, and in particular relates to a manual and electric conversion knob of a reclosing mechanism of a circuit breaker. Background technique [0002] At present, the intelligent molded case circuit breakers sold on the market usually have a manual automatic (electric) integrated reclosing mechanism to realize manual opening and closing or electric opening and closing of the circuit breaker according to different needs. According to the reclosing mechanism of different structures, the manual and electric conversion parts used as manual and electric conversion devices are mainly the following two types, such as figure 1 denoted cam-type components, and figure 2 Represents a wedge-shaped button. [0003] In actual use, figure 1 The cam type parts shown are mostly suitable for applications such as image 3 The reclosing mechanism in which the gear and the rack are engaged is shown...
