[0038] Example 1

[0039] This embodiment provides a universal three-station isolation grounding mechanism, as shown in the attached Figure 1-5 As shown, including:

[0040] The frame 11 is provided with a receiving cavity.

[0041] The first operating mechanism 12 is accommodated in the accommodating cavity and includes an isolation shaft 121, which is used to cooperate with an external operating rod or handle to form a driving effect.

[0042] The second operating mechanism 13 is accommodated in the accommodating cavity and includes a grounding shaft 131, which is used to cooperate with an external operating rod or handle to form a driving effect.

[0043] The output plate 14 is accommodated in the accommodating cavity and rotates relative to the accommodating cavity. The output plate 14 cooperates with the output end of the first operating mechanism 12 and the output end of the second operating mechanism 13, that is, the action of the output end of the first operating mechanism 12 will drive the output plate 14 to rotate; similarly, the action of the output end of the second operating mechanism 13 will drive the output plate 14 to rotate. The output plate 14 is provided with a first limiting groove 141, and the number of the first limiting grooves 141 is two, and the two first limiting grooves 141 are symmetrically arranged.

[0044] The output shaft 15 is linked with the output plate 14 , that is, when the output plate 14 rotates, the output shaft 15 also rotates synchronously, and the rotation angle of the output shaft 15 is consistent with the rotation angle of the output shaft 15 .

[0045] The first limiting structure includes a first limiting member 16. Here, the number of the first limiting members 16 is also two, and the two first limiting members 16 are arranged in a one-to-one correspondence with the two first limiting grooves 141. The first limiting member 16 is adjustably connected to the frame 11. The adjustable connection specifically means that the position of the first limiting member 16 on the frame 11 can be adjusted, so that the length of the first limiting member 16 from the corresponding first limiting groove 141 changes. Here, the first limiting member 16 is located on the rotation trajectory of the corresponding first limiting groove 141. With this structural setting, the length adjustment of the first limiting member 16 is achieved by adjusting the position of the first limiting member 16 relative to the frame 11, so that the rotation angle of the output plate 14 can be selected, so as to achieve the desired angle of the output shaft 15, meet the universal requirements, and are suitable for different types of three-station isolation grounding mechanisms.

[0046] Specifically, as attached Figure 1-3As shown, the frame 11 is provided with a connecting piece 17, and the connecting piece 17 is connected and fixed to the other parts of the frame 11. The connecting piece 17 is provided with a first through hole 171. The first limiting member 16 is provided with at least two second through holes 161, and the number of the second through holes 161 here can be adjusted according to actual needs, and the number of the second through holes 161 can also be more. When the first limiting member 16 is matched with the connecting piece 17, the first through hole 171 and one of the second through holes 161 are coaxially arranged, and the pin 18 passes through the first through hole 171 and is connected to the second through hole 161, forming a connection and fixing effect between the connecting piece 17 and the first limiting member 16. In this embodiment, the connecting piece 17 is located above the first limiting member 16, and the two form a fitting and fixing effect. The setting of the connecting piece 17 makes it more convenient to connect and fix the connecting piece 17 with the first limiter 16. The pin 18 forms a connection and fixing effect at different positions with the first through hole 171 and different second through holes 161, thereby adjusting the position of the first limiter 16 relative to the connecting piece 17, thereby adjusting the length of the first limiter 16 extending outside the connecting piece 17 to meet the requirements of different angles of the output shaft 15. Those skilled in the art can set the number of second through holes 161 according to actual needs to meet a wide range of needs. In addition, the pin 18 can also be replaced by a rivet or a self-tapping screw or a bolt in combination with a nut; or two adjacent second through holes 161 are connected to form a long hole, which can form a fixing effect at different positions. However, with this structure, the accuracy cannot be well controlled, and a scale can be printed on the first limiter 16 to improve the accuracy.

[0047] Specifically, as attached Figure 4 As shown, the frame 11 is provided with a connecting piece 17, and the connecting piece 17 is connected and fixed with the other parts of the frame 11. The connecting piece 17 is provided with a first through hole 171, and the first limiter 16 is provided with at least two fixing columns 162. The number of the fixing columns 162 can be adjusted according to actual needs, and the number of the first through holes 171 and the number of the fixing columns 162 are set correspondingly. The setting of the connecting piece 17 makes the connection and fixation between the connecting piece 17 and the first limiter 16 more convenient. By cooperating with different fixing columns 162 and the first through holes 171, the fixing effects at different positions are formed to meet the requirements of different angles of the output shaft 15. In addition, the fixing column 162 can also be set on the connecting piece 17, and the first through hole 171 is set on the first limiter 16, so as to realize the connection and fixation between the connecting piece 17 and the first limiter 16.

[0048] Specifically, as attached Figure 1-4As shown, the frame 11 also includes a connecting column 19, an upper plate and a lower plate 20. The upper plate and the lower plate 20 are arranged in parallel up and down, the upper plate is located at the top, and the lower plate 20 is located at the bottom. A accommodating cavity is formed between the upper plate and the lower plate 20. The two ends of the connecting column 19 are respectively connected to the upper plate and the lower plate 20. The connecting piece 17 is sleeved on the connecting column 19 and connected and fixed to the connecting column 19. Through the cooperation between the connecting column 19 and the connecting piece 17, the overall strength is improved to prevent the first limit member 16 from malfunctioning during use. At the same time, the connecting column 19 also plays the role of supporting and fixing the upper plate and the lower plate 20. In addition, it should be noted that the isolation shaft 121 and the grounding shaft 131 both extend upward through the upper plate. In this embodiment, the upper plate and the lower plate 20 have similar structures, so they are not reflected in the accompanying drawings.

[0049] Specifically, as attached Figure 1-4 As shown, the first operating mechanism 12 and the second operating mechanism 13 are symmetrically arranged. The first operating mechanism 12 and the second operating mechanism 13 are symmetrically arranged, and the lower ends of both are matched with the output plate 14, so the output plate 14 is also symmetrically arranged, and the number of the same first limit members 16 is also two, and the two first limit members 16 are also symmetrically arranged. In this embodiment, only the first operating mechanism 12 is described as an example, and the second operating mechanism 13 is not described in detail.

[0050] Specifically, as attached Figure 1-5 As shown, it also includes a main spring 21 and a second limiting structure. The first operating mechanism 12 includes a push plate 22, a spring seat 23, a striker 24 and a dial 25. The isolation shaft 121 is linked with the push plate 22. One end of the spring seat 23 is located on the motion track of the push plate 22. The lower end of the spring seat 23 cooperates with the striker 24. The striker 24 is linked with the dial 25. The dial 25 drives the output plate 14 to rotate. One end of the main spring 21 abuts against the spring seat 23, and the other end of the main spring 21 abuts against the spring seat 23 of the second operating mechanism 13. The second limiting structure includes a second limiting member 26. The second limiting member 26 is adjustably connected to the frame 11. The second limiting member 26 is located on the motion track of the striker 24. The second limiter 26 has the same function as the first limiter 16, both of which are to limit the rotation angle of the output shaft 15, that is, when the output shaft 15 rotates to a certain angle, the first limiter 16 abuts against the first limiter groove 141, and the second limiter 26 abuts against the collision plate 24. Here, the connection structure between the second limiter 26 and the frame 11 is similar to the connection structure between the first limiter 16 and the frame 11. The setting of the second limiter 26 also forms an angle limitation to meet the use requirements in different situations. In this embodiment, the output end of the first operating mechanism 12 and the output end of the second operating mechanism 13 are the dials 25 correspondingly set between the two.

[0051] Specifically, as attached Figure 1-5As shown, the detachable connection between the second stopper 26 and the frame 11 can be a bolt connection or a pin 18 connection. Here, the second stopper 26 also cooperates with the corresponding connecting column 19 to form a connection and fixation effect. In this embodiment, the number of connecting columns 19 is three, two of which are correspondingly fixed with different second stoppers 26, and one of the connecting columns 19 is fixed with the first stopper 16.

[0052] Specifically, as attached Figure 5 As shown, the first operating mechanism 12 further includes a pin 27, and the striker 24 is provided with a waist-shaped groove 241, and the pin 27 slides in the waist-shaped groove 241. The cooperation between the pin 27 and the waist-shaped groove 241 can better achieve the control effect of the rotation stroke, and a driving effect is formed by the pin 27 and the side wall of the waist-shaped groove 241 abutting against each other.

[0053] Specifically, the output plate 14 is fixed with a shaft sleeve 28, and the dial 25 is provided with a U-shaped groove 251 that cooperates with the shaft sleeve 28. The cooperation between the shaft sleeve 28 and the U-shaped groove 251 can better achieve a driving effect.

[0054] Specifically, the entire transmission process is that the isolation shaft 121 is rotated by the operating handle to drive the push plate 22 to rotate. At this time, the push plate 22 drives the spring seat 23, and the spring seat 23 compresses the main spring 21. After the main spring 21 passes the center, the kinetic energy of the compressed main spring 21 is used to drive the pin 27. The pin 27 slides in the waist-shaped groove 241 until the pin 27 abuts against the side wall of the waist-shaped groove 241, driving the impact plate 24 to rotate. At the same time, the impact plate 24 drives the dial 25 to rotate. The U-shaped groove 251 on the dial 25 cooperates with the shaft sleeve 28 to form the rotation of the output plate 14, and also drives the output shaft 15 to rotate. When the first limit member 16 abuts against the first limit groove 141, the second limit member 26 and the impact plate 24 also abut at the same time, forming a limiting and fixing effect of the output shaft 15. By adjusting the length from the first limit member 16 to the output plate 14 and the length from the second limit member 26 to the impact plate 24, the rotation angle of the output shaft 15 can be controlled, which can adapt to three-position isolating and grounding switches with multiple angle changes, make production serialized, and thus meet the needs of different three-position isolating and grounding switches.

[0055] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
