[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] A manual operating mechanism for a transfer switch, such as Figure 1-Figure 9 As shown, it includes a switch body 1, a handle 2 is clamped on one side of the switch body 1, an insertion hole 3 is penetrated through one side of the switch body 1, an insert block 19 is rotatably connected inside the switch body 1, the insert block 19 and the insertion hole 3 are corresponding in position, and the insert block 19 and the insertion hole 3 are both plugged and matched with one end of the handle 2;

[0030] The plug block 19 is rotatably connected to the conversion block 6 at one end away from the insertion hole 3, and an iron core assembly is fixedly connected to the bottom of the conversion block 6. A square shaft 8 is rotatably connected in the switch body 1, and a driving seat 7 is fixedly connected to the side wall of the square shaft 8. One side of the conversion block 6 is rotatably connected to one side of the driving seat 7, and one side of the bottom of the driving seat 7 is rotatably connected to a rotating arm 9. A rotating plate 12 is sleeved on the end of the rotating arm 9, and a driving shaft 11 for driving the switch body 1 to operate is fixedly connected to one side of the rotating plate 12.

[0031] When the conversion switch is in manual state, remove the handle 2, insert the end of the handle 2 into the bayonet of the plug block 19 through the insertion hole 3, and press down the handle 2 to control the rotation of the plug block 19. The drive seat 7 and the square shaft 8 are pulled by the conversion block 6 to rotate at the same time, so that the rotating arm 9 at the bottom of the driving seat 7 drives the rotating plate 12 to rotate, and the driving shaft 11 rotates, thereby controlling the opening and closing state of the switch device. When the handle 2 is separated from the plug block 19, the core assembly will pull the conversion block 6 to reset and change the opening and closing state of the switch device. The conversion switch drives the internal parts of the switch device to operate by inserting and pressing down the handle 2, increases the distance between the switch device and the operator, improves safety performance, and uses the lever arm principle for transmission, so the force required for manual operation is reduced, the space required for operation is smaller, and it is more convenient for users to operate.

[0032] The driving seat 7 is shaped as a triangle, the square shaft 8 is located in the middle of the driving seat 7, the rotating arm 9 and the conversion block 6 are respectively connected to the two ends of the driving seat 7, and the iron core assembly includes a double-headed screw 5, the top of the double-headed screw 5 is fixed to the bottom of the conversion block 6, and the side wall of the double-headed screw 5 is fixed with a power iron core 4.

[0033] like Figure 5-Figure 9 As shown, the rotating arm 9 and the conversion block 6 are respectively located on the two corners of the driving seat 7. When the conversion block 6 pulls the driving seat 7 to rotate, the other corner of the driving seat 7 will drive the rotating arm 9 to operate, forming a linkage structure. The power iron core 4 and the double-headed screw 5 serve as the force-bearing parties driven by the handle 2, which can convert the up and down movement of the iron core into the rotational movement of the driving seat 7, which is convenient for driving.

[0034] A fixing plate 21 is vertically fixed in the switch body 1 , one end of the square shaft 8 is rotatably connected to the fixing plate 21 , and the rotating arm 9 and the rotating plate 12 are respectively located on both sides of the fixing plate 21 .

[0035] like Figure 3 As shown, the fixed plate 21 separates the rotating arm 9 and the rotating plate 12 , and a cavity of a certain area is provided on the fixed plate 21 , which will not affect the rotation of the rotating arm 9 driving the rotating plate 12 to rotate.

[0036] The fixing plate 21 is fixedly connected to a round shaft 20 near one side of the insertion hole 3 , the insert block 19 is rotatably connected to the side wall of the round shaft 20 , the end of the rotating arm 9 is fixedly connected to the connecting shaft 10 , and the rotating plate 12 is sleeved on the connecting shaft 10 .

[0037] like Figure 2-Figure 8 As shown, the plug block 19 rotates on the circular shaft 20, and the connecting shaft 10 is connected to the rotating plate 12. When the rotating arm 9 is driven by the driving seat 7, the rotating arm 9 will push the rotating plate 12 to rotate. A cavity is opened on the rotating plate 12, and the connecting shaft 10 can move to a certain extent in the cavity, so that the rotating arm 9 can push the rotating plate 12 to rotate.

[0038] A protrusion 13 is fixedly connected to one side of the rotating plate 12, and a micro switch 14 is fixedly connected to one side of the fixed plate 21 close to the rotating plate 12, and the protrusion 13 and the contact point of the micro switch 14 are in contact and fit.

[0039] like Figure 6 , Figure 8 As shown, when the rotating plate 12 is driven to rotate, the protrusion 13 will contact the contact point of the micro switch 14, so that the opening and closing state of the switching switch can be determined.

[0040] The fixing plate 21 is fixedly connected to a shaft 16 on one side close to the driving seat 7 , and a clamping plate 17 is rotatably connected to the side wall of the shaft 16 . An arc groove 18 is formed at the end of the clamping plate 17 , and the bottom of the driving seat 7 is clamped and matched with the arc groove 18 .

[0041] like Figure 8 , Fig. 9 As shown, when the drive seat 7 rotates a certain amplitude, the end of the card plate 17 will be squeezed until the card slot and the bottom of the drive seat 7 are engaged, applying a certain reset resistance to the drive seat 7 to prevent the conversion block 6 from resetting and pushing the handle 2 to disengage. When the handle 2 is inserted into the plug block 19, the handle 2 can be engaged to prevent the handle 2 from being pushed out.

[0042] The working principle of a manual operating mechanism of a transfer switch provided by the utility model is as follows:

[0043] By inserting the handle 2 into the plug block 19, the plug block 19 and the conversion block 6 drive seat 7 are controlled to rotate, so that the rotating arm 9 drives the rotating plate 12 and the driving shaft 11 to rotate, thereby controlling the state of the switch device. The handle 2 is inserted and pressed down to drive the internal parts of the switch device to operate, thereby increasing the distance between the switch device and the operator and improving the safety performance. In addition, the lever arm principle is used for transmission, so the force required for manual operation is reduced, the space required for operation is smaller, and it is more convenient for users to operate.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
