[0034] Example 1

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, this embodiment provides a manual operating mechanism of a dual power conversion switch. The dual power conversion switch is provided with a common manual operating rotating mechanism 1 connected to a common power source and a backup manual operating mechanism 2 connected to a backup power source. Both the common manual operating rotating mechanism 1 and the backup manual operating mechanism 2 are provided with a push plate 101.

[0036] The manual operating mechanism includes a rotating shaft 3 and a connecting rod 4. One end of the connecting rod 4 is provided with a connecting rod through hole 401 which cooperates with the rotating shaft 3 for rotation transmission. The push plate 101 is provided with a push plate through hole 102 which cooperates with the connecting rod 4. One end of the rotating shaft 3 is provided with a rotating groove 301, and the other end is connected to the connecting rod through hole 401. The end of the connecting rod 4 away from the rotating shaft 3 is located in the push plate through hole 102.

[0037] In this solution, an external handle is inserted into the rotating groove 301 of the rotating shaft 3 to drive the rotating shaft 3 to rotate, and the rotating shaft 3 will drive the connecting rod 4 to rotate. The end of the connecting rod 4 connected to the push plate 101 will drive the push plate 101 to move linearly, driving the corresponding normal power supply or backup power supply to close or open.

[0038] This structure can realize manual opening and closing of the power supply only through a rotating shaft 3 and a connecting rod 4. The overall structure is streamlined and easy to drive. During operation, the normal power supply or the backup power supply can be closed by rotating the manual operating mechanism by turning the handle. There is no mechanism for selecting the direction, and it can be operated with one hand, freeing both hands and preventing misoperation.

[0039] Preferably, Figure 4 As shown, the manual operating mechanism also includes a retaining spring 5, which is connected to the bottom of the rotating shaft 3 and is used to support the connecting rod 4. The retaining spring can elastically support the connecting rod 4 at the bottom of the rotating shaft 3 to reduce friction and improve the rotation efficiency of the connecting rod 4.

[0040] like Figure 3 As shown, the rotating shaft 3 and the connecting rod 4 are supported by the shell 6 of the dual power conversion switch. Preferably, the shell 6 is provided with a shell through hole 601, and the connecting rod 4 is provided with one end of the connecting rod through hole 401 and the bottom of the rotating shaft 3 is located in the shell through hole 601, the end of the connecting rod 4 is limited by one end of the shell through hole 601, and the bottom of the rotating shaft 3 is limited by the other end of the shell through hole 601; the movement of the connecting rod 4 and the bottom of the rotating shaft 3 is limited by the shell through hole 601.

[0041] Optionally, in order to support the rotating shaft 3 without hindering the self-rotation of the rotating shaft 3, the shell 6 is provided with a first U-shaped support plate 602 and a second U-shaped support plate 603 for supporting the rotating shaft 3, the first U-shaped support plate 602 is recessed toward a first direction, and the second U-shaped support plate 603 is recessed toward a second direction, and the first direction and the second direction are opposite.

[0042] In this embodiment, the first U-shaped support plate 602 and the second U-shaped support plate 603 both form semi-cylindrical recessed grooves and are respectively located on both sides of the upper and lower ends of the rotating shaft 3 to support the rotating shaft 3 at the upper and lower ends of the rotating shaft 3 without hindering the self-rotation of the rotating shaft 3.

[0043] The housing 6 is provided with a sliding through hole 604 for the push plate 101 to slide horizontally. One side of the push plate 101 is bent to form a bent portion passing through the sliding through hole 604. The push plate through hole 102 is located on the bent portion.

[0044] The setting of the push plate through hole 102 needs to be able to convert the circular motion of the end of the connecting rod 4 into the linear motion of the push plate 101, so the shape of the push plate through hole 102 can be selected as a rectangle, and the long axis direction of the push plate through hole 102 is perpendicular to the distribution direction of the sliding through hole 604.

[0045] The connecting rod through hole 401 needs to be connected to the rotating shaft 3 and rotate with the rotating shaft 3 at the same time. Therefore, the shape of the connecting rod through hole 401 cannot be set to be circular, and can be optionally polygonal, elliptical or irregular.

[0046] Optionally, in this embodiment, the connecting rod 4 is a rod-shaped structure bent at 90 degrees, one end of which is connected to the rotating shaft 3, and the other end is bent and inserted into the push plate through hole 102. It can be formed by flattening and bending round steel, and the bending can be performed by cold forging.

[0047] Preferably, the push plates 101 of the commonly used manual operating rotating mechanism 1 and the backup manual operating mechanism 2 are of split structure; that is, the push plates 101 of the two are not connected, and the push plates 101 of the two are respectively connected to the corresponding rotating shafts 3 and connecting rods 4, and the corresponding rotating shafts 3 and connecting rods 4 can be driven separately by the corresponding manual operating mechanisms to realize manual closing and opening, and the two manual operating mechanisms are independent and do not affect each other.

[0048] Optionally, the rotation groove 301 of the rotating shaft 3 is a hexagonal groove, which can be driven to rotate by a hexagonal wrench.

[0049] When using the structure of this solution, when the manual operating mechanism is needed, the hexagonal wrench is used to rotate the shaft in the common manual operating mechanism when the common power is turned on, and the shaft is rotated a certain angle according to the design direction to turn on the common power of the switch; similarly, when the backup power is turned on, the hexagonal wrench is used to rotate the shaft in the backup manual operating mechanism, and the shaft is rotated a certain angle according to the design direction to turn on the backup power of the switch. When manual operation is not required, the hexagonal wrench needs to be removed.

[0050] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
