[0032] Example 1

[0033] A dual power conversion switch includes a housing, a driving mechanism, a conversion mechanism, and a wiring device. The driving mechanism drives the conversion mechanism to conduct different circuits on the wiring device. Figure 1-7 The switch control assembly shown.

[0034] The switch control assembly includes a control cover 1 and a switch assembly. The control cover 1 has a switch portion 11, and the switch portion 11 has a control port 12. The switch assembly includes a micro switch 5, a lock plate 2 slidably connected to the switch portion 11, and the two ends of the lock plate 2 are respectively a contact end close to the micro switch 5 and a control end extending out of the control port 12. When the control end is subjected to an external force, the lock plate 2 has a first position in which the contact end slides relative to the switch portion 11 so as to contact the micro switch 5 to open the micro switch 5, and the lock plate 2 has a second position in which the contact end slides relative to the switch portion 11 so as to separate from the micro switch 5 to close the micro switch 5. When the lock plate 2 is in the second position, it is locked with the positioning structure. The control cover 1 is located on the housing, and the micro switch 5 is connected to and controls the start and close of the drive motor in the drive mechanism. When the micro switch 5 is turned on, the drive motor circuit is turned on, so that the drive motor is controlled by an electrical signal; when the micro switch 5 is turned off, the drive motor is powered off, so that the dual power conversion switch cannot be controlled by the circuit.

[0035] The control end has a lock slot 25. When the lock plate 2 is in the first position, the lock slot 25 is located on the surface of the control surface cover 1. When the lock plate 2 is in the second position, the control end drives the lock slot 25 to move so that the lock slot 25 extends out of the edge of the control surface cover 1 and then locks with the positioning structure. After the lock slot 25 extends out of the edge of the control surface cover 1, it is convenient for the staff to padlock or insert a positioning pin to lock the position of the lock plate 2, thereby preventing the micro switch 5 from being opened.

[0036] The inner wall of the control surface cover 1 is provided with a first card slot 111, a second card slot 112, and a third card slot 113 in pairs, and two pairs of card protrusions 23 are provided on both sides of the lock plate 2; when the lock plate 2 is in the first position, the two pairs of card protrusions 23 are respectively inserted into the first card slot 111 and the second card slot 112, and when the lock plate 2 is in the second position, the two pairs of card protrusions 23 are respectively inserted into the second card slot 112 and the third card slot 113.

[0037] The control surface cover 1 is provided with a sliding groove on the inner wall, and the locking groove protrudes outward from the side of the sliding groove. The lock plate 2 is provided with a deformation groove 24 at the inner side corresponding to the locking protrusion 23; in this embodiment, the locking protrusion 23 has a guiding inclined surface to facilitate its sliding out of the locking groove. After the locking protrusion 23 moves out of one locking slot, it is squeezed by the inner wall of the sliding groove to compress the deformation groove 24, so that the lock plate 2 slides smoothly until it enters another locking slot.

[0038] Furthermore, the control surface cover 1 is provided with a first operating hole 13, and the lock plate 2 is provided with a second operating hole 21. When the lock plate 2 is in the first position, the first operating hole 13 and the second operating hole 21 correspond to each other. When the lock plate 2 is in the second position, the second operating hole 21 is away from the first operating hole 13 and the lock plate 2 covers at least part of the first operating hole 13. A positioning plate 3 and a base 4 are provided below the lock plate 2, and the positions of the positioning plate 3 and the base 4 and the control surface cover 1 are relatively fixed, and the lock plate 2 is clamped between the control surface cover 1 and the positioning plate 3. The third operating hole 31 is arranged on the positioning plate 3; a mounting seat 42 is protrudingly arranged on the base 4, and a fourth operating hole 41 is provided on the mounting seat 42. The positioning plate 3 is sleeved on the mounting seat 42 through the third operating hole 31, and the fourth operating hole 41 corresponds to the first operating hole 13; the driving mechanism includes a driving shaft matched with the driving motor, one end of the driving shaft is adapted to the operating handle, and the operating handle passes through the first operating hole 13, the second operating hole 21, and the third operating hole 31 at the same time to match the driving shaft.

[0039] At this time, the dual power conversion switch has two operating modes: motor control conversion and manual operation conversion. When the lock plate 2 is in the second position, the micro switch 5 is closed, and the drive motor is powered off, so that the dual power conversion switch cannot be operated through circuit control. At the same time, the lock plate 2 blocks at least part of the first operating hole 13, and the operating handle cannot pass through the first operating hole 13, the second operating hole 21, and the third operating hole 31 at the same time to cooperate with the drive shaft, so that the dual power conversion switch cannot be operated through manual control.

[0040] A guide block 32 is disposed on the positioning plate 3 , and the guide block 32 extends into the travel groove 22 on the lock plate 2 . The guide block 32 limits the sliding travel of the lock plate 2 relative to the control surface cover 1 and the positioning plate 3 .

[0041] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
