DETAILED DESCRIPTION
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1-3 As shown, an emergency tripping mechanism padlock device for preventing misoperation includes a fixed frame 5, a panel 16, a rotary directional gate 18, a center key 19, and a guide rod 11. The panel 16 is mounted on the fixed frame 5, and a mounting platform 4 is provided on the panel 16. A mounting sleeve 26 is provided on the fixed frame 5, and the mounting sleeve 26 is located inside the mounting platform 4. The rotary directional gate 18 is rotatably mounted inside the mounting sleeve 26. The center key 19 is slidably mounted inside the rotary directional gate 18, and one end of the center key 19 passes through the rotary directional gate 18. A swing frame 12 is rotatably mounted on the fixed frame 5, and the guide rod 11 slides on the swing frame 12. A swing reset component is provided between the swing frame 12 and the rotary directional gate 18. The swing reset component applies a non-coaxial force to the guide rod 11, which is different from that of the center key 19. A gate cover 2 is rotatably mounted on the mounting platform 4. Both the gate cover 2 and the mounting platform 4 are provided with lugs 1. The lugs 1 are provided with padlock holes 15 and lead seal holes 17.
[0018] The swing reset component includes a rotating shaft 24, a torsion spring 23, a fixing block 20, a mounting bracket 7, a hinge rod 6, and a positioning pin 13. The lower end of the rotary directional brake 18 passes through the fixing block 20, and the two are fixed together by a positioning pin 21. The mounting bracket 7 is fixed to the swing frame 12 with bolts, and the positioning pin 13 is fixed to the fixing block 20. One end of the hinge rod 6 has a through hole for the positioning pin 13 to pass through, and the other end is rotatably connected to the mounting bracket 7. The torsion spring 23 is sleeved on the rotating shaft 24 and applies torque to the rotating shaft 24. Both ends of 24 are rotatably connected to the fixed frame 5, and the rotating shaft 24 is fixedly connected to the swing frame 12. Before rotating the knob to open the directional control 18, the guide rod 11 and the center key 19 are not coaxial. When emergency opening is required, rotating the knob to open the directional control 18 causes the fixed block 20 to rotate synchronously, and the hinge rod 6 pulls the mounting frame 7 and the swing frame 12. When the swing frame 12 is under tension, it will drive the rotating shaft 24 to rotate, causing the torsion spring 23 to continue to store force. When the guide rod 11 rotates to the coaxial state with the center key 19, as... Figure 1 As shown, at this time, the center key 19 can be pressed, causing the center key 19 to push the guide rod 11 to slide and contact the circuit breaker trip button, thereby achieving the effect of tripping.
[0019] The swing frame 12 is provided with two limiting blocks 10, and a first spring 22 is arranged between the two limiting blocks 10, the first spring 22 is sleeved on the guide rod 11, the guide rod 11 is provided with a first stop ring 9, the first spring 22 exerts a force on the guide rod 11 to approach the fixed block 20, when the guide rod 11 is pushed by the center key 19, the first spring 22 is compressed, so that the guide rod 11 is in contact with the circuit breaker tripping button, thereby achieving the tripping effect.
[0020] The rotating shaft 24 is provided with a second stop ring 25 at both ends penetrating through the fixed frame 5 and the swing frame 12, and the second stop ring 25 can limit the rotating shaft 24 from falling off the fixed frame 5.
[0021] The knob tripping device 18 is provided with a second spring 8 for resetting the center key 19, when the center key 19 is pressed, the center key 19 pushes the guide rod 11 to compress the first spring 22, so that one end of the guide rod 11 is in contact with the circuit breaker tripping button, thereby achieving the tripping effect, and after the tripping is completed, the second spring 8 can reset the center key 19.
[0022] The panel 16 is provided with an identification arrow 14 indicating the rotation of the knob tripping device 18, which can inform the operator of the rotation direction of the knob tripping device 18, and the knob tripping device 18 is provided with a protrusion 3, which can facilitate the operator to rotate the knob tripping device 18.
[0023] Working principle: when the cover 2 is rotated and covered on the mounting table 4, the padlock and the lead seal pass through the padlock hole 15 and the lead seal hole 17, which can ensure that the knob tripping device 18 is not exposed to the outside, which not only achieves the dustproof effect, but also plays a first layer of protection, when the padlock is opened and the lead seal is damaged, the cover 2 is opened, the knob tripping device 18 is rotated along the identification arrow 14, the swing frame 12 drives the guide rod 11 to rotate, and the guide rod 11 is coaxial with the center key 19 and the circuit breaker tripping button, then the center key 19 is pressed in this state, thereby achieving the tripping effect, which can achieve the second layer of protection, and the double-layer protection can effectively avoid the misoperation.
