Although various elements of the present invention may be described using expressions such as "first" and "second," they are not intended to limit the respective elements. The above expressions are not intended to limit the order or importance of the corresponding elements. The above description is intended to distinguish one element from another, and "a first element" may be written as "a second element", and similarly "a second element" may be written as "a first element", without departing from the scope of the present invention. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In addition, the directional terms such as "upper", "lower", "left", "right", and the like mentioned herein are used only for showing relative positional relationships with respect to the drawings, and when the absolute position of the object to be described is changed, the relative positional relationships may be changed accordingly.

The specific structure and operation principle of the supporting structure for the operating mechanism of the vacuum circuit breaker according to the present invention will be described with reference to fig. 1 to 3. The supporting structure of the operating mechanism of the vacuum circuit breaker is used for installing the operating mechanism of the vacuum circuit breaker on the surface of a gas box body of a switch cabinet, and the vacuum circuit breaker is arranged in the gas box and is connected with the operating mechanism of the vacuum circuit breaker outside the gas box through a corrugated pipe.

Preferably, the support structure is integrally formed by die-casting, in contrast to conventional actuator supports consisting of a plurality of parts. The utility model provides a supporting mechanism will strengthen annex such as panel beating steel sheet, mechanism's support, spring bracket, interlocking support and all integrate into a die-casting aluminium part, reduce the part cost effectively, improve assembly efficiency. And also. The die-casting process has flexible 3D modeling, can add parts according to requirements, and has lower cost.

As shown in fig. 1, the support structure includes a first mounting surface 100 facing the case and a second mounting surface 200 facing the user opposite to the first mounting surface 100, and first and

second side walls

300 and 400 arranged oppositely, thereby enclosing a box-like structure as shown in the drawing.

The support structure includes a first chamber C1 and a second chamber C2. A first cavity C1 is located between the two

side walls

300, 400 and opens toward the second mounting face 200 for receiving the operating mechanism spindle. A second chamber C2 is located between the two side walls and adjacent to the first chamber C1 for receiving the oil cushioning components of the vacuum interrupter, the second chamber C2 being open to the first mounting face 100.

Referring to fig. 3, the first mounting face 100 is provided with a first opening 101 for receiving a bellows of a vacuum interrupter, the first opening 101 leading to the first chamber C1. The first mounting surface 100 is further provided with a plurality of first mounting portions 102 for fastening the support structure to the cabinet; and a plurality of second mounting portions 103 surrounding the first opening 101 for securely connecting the bellows to the support structure, avoiding deformation of the mounting surface. Alternatively, the first and second mounting

portions

102 and 103 may be threaded holes of the same or different specifications. The position of the threaded hole can be determined according to actual conditions.

At least one reinforcement post 10 is disposed about the first opening 101 and extends between the first mounting surface 100 and the second mounting surface 200. The illustrated first opening 101 is provided with a cylindrical reinforcing column on each of the left and right sides thereof to increase strength. The cylindrical reinforcing part beside the corrugated pipe hole is a unique shape of a die-cast aluminum part and cannot be made by a sheet metal part.
