[0023] In order to make the purpose, technical solution and advantages of the technical solution of the present disclosure clearer, the technical solution of the embodiment of the present disclosure will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present disclosure. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] Compared to the embodiments shown in the drawings, feasible implementations within the scope of the present disclosure may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0025] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the present disclosure belongs. The words "first", "second" and similar words used in the patent application specification and claims of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. When the number of components is not specified, the number of components may be one or more; similarly, words such as "one", "the", "said" and the like do not necessarily indicate a quantitative limitation. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Up", "down", "left", "right" and the like are only used to indicate the relative orientation relationship when the device is in use or the orientation relationship shown in the drawings. When the absolute position of the described object changes, the relative position relationship may also change accordingly.

[0026] Combine the following Figures 1 to 8 The transmission system including the rotating shaft structure according to the present application is described as follows. The rotating shaft structure includes a rotating shaft 1, which is rotatably mounted on a housing 2 and can be rotated in a first rotation position (such as Figure 5 and 6 as shown) and a second rotational position (as shown Figure 1 and Figure 2 In addition, the rotating shaft 1 is also configured to be able to translate between a first translation position and a second translation position in a direction along its rotation axis L. That is, in addition to rotating, the rotating shaft can also translate.

[0027] The blocking assembly 3 is pivotally connected to the rotating shaft 1 and can be in a first posture (eg Figure 1 and Figure 2 as shown) and the second posture (as shown Figure 7 and Figure 8 As shown), it can also be in an intermediate posture between the first posture and the second posture, such as Figure 5 and 6 As shown. The matching blocking member 4 is fixed to the housing, and can be a component separated from the housing, or can be formed integrally with the housing. When the blocking assembly 1 is in the first posture, the matching blocking member is outside the translation path of the rotating shaft from the first translation position to the second position, thereby allowing the rotating shaft to translate to the second translation position. When the blocking assembly is in the second posture, the matching blocking member is in the translation path of the rotating shaft from the first translation position to the second position, thereby blocking the rotating shaft from translating to the second translation position.

[0028] The blocking assembly 3 includes a housing 31 , a protrusion 32 protruding inward from the inner wall of the housing, and an elastic member 33 . The housing is sleeved on the rotating shaft 1 , and the elastic member 33 is arranged between the insertion portion 11 of the rotating shaft 1 inserted into the housing and one side of the protrusion 32 .

[0029] like Figure 1 and 2 As shown, the rotating shaft 1 is in the second rotation position and the first translation position, the blocking assembly is in the first posture, and the elastic member 33 is compressed between the insertion portion 11 of the rotating shaft and the protrusion 32 in the first compression state. Figure 1 As shown, the mating stopper 4 is outside the translation path of the rotating shaft from the first translation position to the second translation position, thereby allowing the rotating shaft 1 to translate from the first translation position to the second translation position.

[0030] like Figure 3 and 4 As shown, the rotating shaft 1 has been translated from the first translation position to the second translation position, but is still in the second rotation position, and the blocking assembly is still in the first posture. The mating blocking member 4 is in the form of a wall, including a first wall 41 and a second wall 42, the first wall and the second wall are spaced apart from each other in a direction perpendicular to the rotation axis of the rotating shaft, so that when the rotating shaft is translated from the first translation position to the second translation position, the gap between the first wall and the second wall accommodates the blocking assembly in the first posture.

[0031] When the rotating shaft 1 is translated to the second translation position, the rotating shaft 1 is rotated from the second rotation position toward the first rotation position along a predetermined direction, and the rotating shaft rotates by a predetermined angle, so that the housing of the blocking assembly abuts against the matching blocking member 4. As the rotating shaft further rotates, the inserted portion of the rotating shaft rotates relative to the protrusion, so that the elastic member is further compressed. After the rotating shaft rotates to the first rotation position, the elastic member is in a second compressed state, such as Figure 5 and 6 shown.

[0032] When the rotating shaft rotates to the first rotating position, the rotating shaft can translate from the second translation position back to the first translation position, so that the housing of the blocking component 3 is disengaged from the abutment with the matching blocking member 4, so that the elastic member 33 is released from the second compressed state to the first compressed state, so that the blocking component is in the second posture, such as Figure 7 and 8 In addition, the matching blocking member 4 is in the translation path of the blocking assembly 3 from the first translation position to the second translation position, in particular from Figure 7 It can be seen in.

[0033] The transmission system of the present application includes the above-mentioned rotating shaft structure and the driven member, the second rotating member is rotatably arranged on the housing 2, and the active member (i.e., the rotating shaft 1) is operably connected to the driven member (not shown), so that when the active member moves, it can drive the driven member to move.

[0034] The present application also provides an operating mechanism for a switchgear, such as Fig. 9 The operating mechanism comprises a transmission system as described above; an operating handle rotatably mounted to the housing, capable of rotating between a closing position and an opening position, and indicating the closing position and the opening position; an active member fixedly connected to the operating handle, capable of rotating together with the operating handle; a driven member operably connected to the active member on one hand, and operably connected to the switch device on the other hand, wherein a first rotation position of the active member corresponds to a closing state of the switch device, and a second rotation position of the active member corresponds to an opening state of the switch device.

[0035] The present application also proposes a switch device assembly, which includes the above-mentioned operating mechanism and a switch device. The switch device can be any type of switch. The second rotating member of the operating mechanism is connected to the switch device by any suitable transmission mechanism, so that the switch device performs a closing and opening operation. For such a transmission mechanism, those skilled in the art can specifically design it as needed, and it is not the focus of this article, so it is not described in this article.

[0036] Through the rotating shaft structure of the present application, it is possible to simply realize that the rotating shaft can only translate to the second translation position in the second rotation position, but cannot translate to the second translation position in the first rotation position. When this is applied to a switch device assembly, it is possible to better realize the operation of the operating mechanism of the switch device assembly and prevent misoperation.

[0037] Although the present invention has been described in the specification and illustrated in the drawings with reference to various embodiments, those skilled in the art will appreciate that the above embodiments are merely preferred implementations, and certain technical features in the embodiments may not be necessary for solving specific technical problems, so that these technical features may be absent or omitted without affecting the solution of the technical problems or the formation of technical solutions; moreover, the features, elements and / or functions of one embodiment may be appropriately combined, coupled or coordinated with the features, elements and / or functions of one or more other embodiments, unless the combination, coupling or coordination is obviously not feasible.
