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.

[0027] A reclosing switch opening and closing indication mechanism, such as Figure 1-Figure 7 As shown, it comprises a housing 1, an indicating port 2 is formed through the upper end of the housing 1, a fixing plate 3 is fixedly connected inside the housing 1, a fixing column 6 is fixedly connected to the fixing plate 3, a sliding cavity 4 is formed through the fixing column 6, and a lifting mechanism for cooperating with a reclosing handle is slidably connected in the sliding cavity 4;

[0028] The upper end of the fixed plate 3 is fixedly connected to a rotating seat 15 at a position on one side of the fixed column 6, and a rotating shaft 16 is fixed in the rotating seat 15. The side wall of the rotating shaft 16 is rotatably connected to a driving arm 17 and a rotating arm 19. One end of the driving arm 17 is squeezed and fitted with the upper end of the jacking mechanism, and the other end is squeezed and fitted with the side wall of the rotating arm 19. An indicating end 20 is fixedly connected to the end of the rotating arm 19 away from the rotating shaft 16, and the indicating end 20 corresponds to the indicating port 2. A reset component for pulling the driving arm 17 to reset is fixedly connected between the middle part of the driving arm 17 and the fixed plate 3.

[0029] The indicating port 2 of the shell 1 is convenient for observing the opening and closing indicating status of the shell 1. It is linked with the closing mechanism inside the reclosing switch through the lifting mechanism. When opening and closing the switch, the lifting mechanism will be driven to rise and fall, so that the upper end of the lifting mechanism lifts the end of the driving arm 17, so that the driving arm 17 rotates, and one end of the driving arm 17 is squeezed and matched with one side of the rotating arm 19, driving the rotating arm 19 to rotate, so that the indicating end 20 rotates at the lower end of the indicating port 2, and the relative position of the indicating end 20 and the indicating port 2 is switched, and the indicating state changes; when the lifting mechanism descends, the reset component pulls the driving arm 17 to rotate, so that one end of the driving arm 17 squeezes the rotating arm 19, rotates the rotating arm 19, and the relative position of the indicating end 20 and the indicating port 2 changes, and the indicating state changes. The opening and closing indicating mechanism of the reclosing switch is well designed, the opening and closing indicating mechanism is clear and accurate, and occupies little space.

[0030] The lifting mechanism includes a driving rod 10, which passes through and is slidably connected to the sliding cavity 4. An extrusion head 14 is fixedly connected to one end of the driving rod 10 close to the driving arm 17. The extrusion head 14 is extruded and matched with one end of the driving arm 17. A spring 13 is sleeved on the side wall of the driving rod 10. One end of the spring 13 is fixedly connected to the side wall of the driving rod 10, and the other end is clamped to the inner wall of the fixed column 6.

[0031] like Figure 1-Figure 7 As shown, the lower end of the driving rod 10 is linked with the opening and closing mechanism inside the reclosing switch. When the driving rod 10 is lifted, the spring 13 is compressed, and the extrusion head 14 squeezes the end of the driving arm 17, so that the driving arm 17 rotates on the rotating shaft 16. When the driving arm 17 rotates, one end presses against the rotating arm 19 below to rotate the rotating arm 19. When the driving rod 10 is not lifted, the spring 13 pushes the driving rod 10 to reset the driving rod 10, and the driving arm 17 is pulled to reset by the reset assembly.

[0032] The reset assembly includes a fixed frame 8 , which is fixed to the fixed plate 3 and located between the fixed column 6 and the rotating seat 15 . A second spring 18 is clamped on the upper end of the fixed frame 8 , and an end of the second spring 18 is clamped on the driving arm 17 .

[0033] like Figure 5-Figure 7 As shown, the main structure of the reset assembly is the second spring 18 and the fixed frame 8. The second spring 18 is in a compressed state and always pulls the drive arm 17. When the lifting mechanism does not press the drive arm 17, the second spring 18 pulls the drive arm 17 to rotate.

[0034] A rectangular plate 11 is fixedly connected to the side wall of the driving rod 10 , a rectangular groove 5 is penetrated through the fixed plate 3 , the rectangular groove 5 is communicated with the sliding cavity 4 , and the rectangular groove 5 is located on the side of the fixed column 6 away from the rotating seat 15 , and the rectangular plate 11 is slidably connected in the rectangular groove 5 .

[0035] like Figure 2 , Figure 5 , Figure 7As shown, the driving rod 10 slides in a straight path through the rectangular plate 11 and the rectangular groove 5 to prevent the driving rod 10 from rotating in the sliding cavity 4.

[0036] The side wall of the driving rod 10 is fixedly connected with a fixing strip 12 , which is located inside the spring 13 , and the fixing strip 12 is slidably connected with the inner wall of the fixing column 6 .

[0037] like Figure 5-Figure 7 As shown, the fixing strip 12 is slidably connected to the inner wall of the fixing column 6 , so that the driving rod 10 slides linearly inside the fixing column 6 .

[0038] An abutment plate 21 is fixedly connected to one end of the driving arm 17 away from the lifting mechanism, and the abutment plate 21 is drivingly engaged with a lower side of the rotating arm 19 away from the lifting mechanism.

[0039] like Figure 5-Figure 7 As shown, the abutment plate 21 is in the same horizontal state as the rotating shaft 16. When the driving arm 17 rotates, the abutment plate 21 will rotate at a certain angle, and the upper end or the lower end of the abutment plate 21 will abut and squeeze one side of the rotating arm 19, driving the rotating arm 19 to rotate.

[0040] The working principle of a reclosing switch opening and closing indication mechanism provided by the utility model is as follows:

[0041] The indicating port 2 of the shell 1 is convenient for observing the opening and closing indicating status of the shell 1. It is linked with the closing mechanism inside the reclosing switch through the lifting mechanism. When opening and closing the switch, the lifting mechanism will be driven to rise and fall, so that the upper end of the lifting mechanism lifts the end of the driving arm 17, so that the driving arm 17 rotates, and one end of the driving arm 17 is squeezed and matched with one side of the rotating arm 19, driving the rotating arm 19 to rotate, so that the indicating end 20 rotates at the lower end of the indicating port 2, and the relative position of the indicating end 20 and the indicating port 2 is switched, and the indicating state changes; when the lifting mechanism descends, the reset component pulls the driving arm 17 to rotate, so that one end of the driving arm 17 squeezes the rotating arm 19, rotates the rotating arm 19, and the relative position of the indicating end 20 and the indicating port 2 changes, and the indicating state changes. The opening and closing indicating mechanism of the reclosing switch is well designed, the opening and closing indicating mechanism is clear and accurate, and occupies little space.

[0042] 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.
