[0027] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below combined with the drawings of the specification.

[0028] In the following description, a lot of specific details are set forth in order to facilitate a full understanding of the utility model, but the utility model can also be implemented in other ways different from the description herein, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0029] Secondly, the "one embodiment" or "embodiment" referred to herein can contain specific features, structures or characteristics in at least one implementation of the utility model. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0030] Embodiment 1, refer to Figures 1-4For the first embodiment of the utility model, this embodiment provides an operating mechanism, including operating piece 100, including first fixed disc 101, action piece 200, including second fixed disc 201, second fixed disc 201 and first fixed disc 101 coaxial and there is interval space S in the middle, second fixed disc 201 is fixedly connected with mutually parallel transmission rod 202 and action rod 203, transmission rod 202 is coaxial with second fixed disc 201, action rod 203 is not coaxial with second fixed disc 201.

[0031] For the miniature circuit breaker inside the plug-in box, there are two ways to operate the on-off of the miniature circuit breaker, specifically, disassembling the plug-in box door or exposing the miniature circuit breaker switch outside the plug-in box, which will affect the protection level of the plug-in box.

[0032] Therefore, the operating piece is moved to the outside of the plug-in box as a whole, and the opening and closing of the miniature circuit breaker is operated through the transmission of the action piece without disassembling the plug-in box door.

[0033] Because the miniature circuit breaker needs a certain rotation area for opening and closing, the activity area or stress area of the action rod is nonlinear, so the action rod 203 is not coaxial with the second fixed disc 201.

[0034] Embodiment 2, refer to Figures 1-4 For the second embodiment of the utility model, it is different from the first embodiment that: the side, away from the second fixed disc 201, of the first fixed disc 101 is symmetrically provided with L-shaped fin 102.

[0035] The axis of the second fixed disc 201 and the first fixed disc 101 is fixedly connected, and the two non-axis positions are detachably connected.

[0036] Among them, the axis of the second fixed disc 201 and the first fixed disc 101 can be connected by bolts, or can be integrally fixedly connected, but finally presents an I-shaped structure, that is, passes through the plug-in box body in the middle, and can rotate on the plug-in box body, to ensure that the fin 102 can rotate the second fixed disc 201 and the first fixed disc 101.

[0037] Further, when the miniature circuit breaker as a whole needs to be locked and the second fixed disc 201 and the first fixed disc 101 are not allowed, at this time, the two non-axis positions of the second fixed disc 201 and the first fixed disc 101 are reinserted with bolts, at this time, the second fixed disc 201 and the first fixed disc 101 are fixed on the plug-in box body, and the fin 102 cannot rotate to operate the second fixed disc 201 and the first fixed disc 101.

[0038] Embodiment 3, refer to Figures 1-4For the third embodiment of the utility model, it is different from the second embodiment that: the action rod 203 includes two parallel push rods 203a, the two ends of the push rod 203a are fixedly connected with the third fixed disc 204 and the fourth fixed disc 205, and the connecting positions of the third fixed disc 204 and the fourth fixed disc 205 with the two ends of the push rod 203a are not located at the shaft centers of the third fixed disc 204 and the fourth fixed disc 205.

[0039] The third fixed disc 204 and the fourth fixed disc 205 are parallel to and coaxial with the second fixed disc 201.

[0040] The action piece 200 further includes a mounting plate 206, the mounting plate 206 is in the shape of a hollow three-prism, and the rotating area surrounded by the push rod 203a, the third fixed disc 204 and the fourth fixed disc 205 is close to one prism of the mounting plate 206.

[0041] The third fixed disc 204 is fixedly connected with the transmission rod 202 and is located on both sides of one bottom surface of the three-prism of the mounting plate 206; and the fourth fixed disc 205 is fixedly connected with another bottom surface of the three-prism of the mounting plate 206.

[0042] Similarly to the second fixed disc 201 and the first fixed disc 101 being located on both sides of the side wall of the plug-in box body, the transmission rod 202 and the third fixed disc 204 are also located on both sides of one bottom surface of the three-prism of the mounting plate 206, which is beneficial to the stability of the transmission rod 202 and ensures the stable rotation of the third fixed disc 204, thereby ensuring the stable and accurate rotation of the rotating area of the two parallel push rods 203a, and avoiding the accidental opening and closing of the miniature circuit breaker.

[0043] Since the miniature circuit breaker is located in the mounting plate, at this time, the opening and closing push piece of the miniature circuit breaker is just inserted into the gap of the two parallel push rods 203a, so that the first fixed disc 101 outside the plug-in box body can drive the second fixed disc 201, the transmission rod 202 and the action rod 203 inside the plug-in box body, and finally make the two parallel push rods 203a play a role respectively, and complete the opening and closing of the miniature circuit breaker.

[0044] Embodiment 4, refer to Figures 5-7 For the fourth embodiment of the utility model, it is different from the previous three embodiments that the embodiment provides a plug-in box, which comprises the operation mechanism described above; further comprising a main body piece 300, comprising a box door 301 and a box body 302, one side wall of the box body 302 is located in the spacing space S; a locking piece 400, comprising a first buckle 401 and a second buckle 402, one end of the first buckle 401 is fixed on the transmission rod 202, the other end is mutually buckled with the second buckle 402, and the second buckle 402 is fixedly connected with the box door 301.

[0045] The first fixing disc 101 is located on the outer wall of the box 302, and the second fixing disc 201 is located on the inner wall of the box 302; the first buckle 401 extends in parallel with the second fixing disc 201.

[0046] The box 302 internally has a mounting plate 206.

[0047] Overall, the first buckle 401 extends in the direction of the rotating area surrounded by the third fixing disc 204, the fourth fixing disc 205 and the push rod 203a, and the micro circuit breaker switching position is closer to the box door of the plug-in box.

[0048] Similarly, the first buckle 401 and the second buckle are also close to the box door of the plug-in box.

[0049] For the plug-in box and the micro circuit breaker inside, in addition to the strict guarantee of the accurate action of the micro circuit breaker itself, the micro circuit breaker in the off state can only allow the opening of the box door of the plug-in box, so it is necessary to consider the interlocking of the micro circuit breaker off state and the box door.

[0050] Specifically, when the first fixing disc 101 is operated outside the box body of the plug-in box, the transmission rod 202 and the action rod 203 can complete the switching of the micro circuit breaker, and the first buckle 401 on the transmission rod 202 can be separated from the second buckle 402, so that the box door 301 fixedly connected with the second buckle 402 is freely disassembled, thereby realizing the interlocking of the micro circuit breaker off and the opening of the plug-in box door.

[0051] On the contrary, when the micro circuit breaker is closed, the plug-in box door is opened and cannot be opened, thereby improving the safety level of the micro circuit breaker, the overall protection level of the plug-in box and the safety level of the personnel.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
