[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Specific embodiments are given below.

[0021] Please refer to Figures 1-3The utility model discloses a charging cabinet with anti -mistouch function switch -on and switch -off button, including the cabinet body 1, be provided with operating mechanism in the cabinet body 1, and operating mechanism includes switch -on button 2 and switch -off button 3, switch -on button 2 and switch -off button 3 all are provided with anti -mistouch mechanism 4, anti -mistouch mechanism 4 includes the fixed setting in the one side of cabinet body 1 and be located switch -on button 2 and switch -off button 3 periphery's limit sleeve 401, the movable through slot 402 is set up on limit sleeve 401, anti -mistouch mechanism 4 still includes the limit cover 403 of bearing rotation setting on switch -on button 2 and switch -off button 3, the limit cover 403 is fixedly provided with the limit rod 404 of movable through slot 402 cooperation on, the limit cover 403 and cabinet body 1 between terminal have spring 405, when, in initial non -operating state, spring 405 relies on the elastic recovery force of itself to pull outwards limit cover 403, limit rod 404 is not in movable through slot 402 at this moment, and limit cover 403 covers switch -on button 2 and switch -off button 3 comprehensively, and limit rod 404 and movable through slot 402 stagger, effectively prevent any direct button accidental touch or press, when needing normal switch -on and switch -off operation, operating personnel first rotate limit cover 403, and limit cover 403 drives limit rod 404 synchronous rotation, when limit rod 404 rotates to movable through slot 402, operating personnel need to exert a downward pressure on limit cover 403, and this pressure is in overcoming the resistance of spring 405 while making spring 405 compression energy storage, and limit cover 403 starts to move down, and the limit rod 404 connected with it also moves in movable through slot 402 synchronously in this moving process, limit cover 403 can trigger switch -on button 2 or switch -off button 3, thereby performing switch -on or switch -off operation, after operation, operating personnel release, and the elastic potential energy of spring 405 can be released, drives limit cover 403 to rebound backstroke, and limit rod 404 also leaves movable through slot 402, because in the rotation operation before pressing limit cover 403, makes spring 405 axial rotation, and spring 405 has the characteristics of torsional spring and stores energy at this time, when limit cover 403 drives limit rod 404 backstroke, once limit rod 404 leaves movable through slot 402, the axial torsional potential energy of spring 405 before accumulation promotes limit cover 403 to reverse, and then makes limit rod 404 angle and movable through slot 402 angle stagger, effectively prevent limit cover 403 from being misoperated and pressing, restore to the initial safe protection state, from the safety point of view, this mechanical structure constructs the protection barrier of multistep, multilevel and has self -recovery function, in the complex and changeable electric power operating environment, whether it is personnel's unintentional collision, the misoperation attempt of unfamiliar equipment personnel, can be intercepted accurately before operating button, greatly reduces the charging cabinet misoperation probability caused by mistouch, guarantees the safety of electric power system operation, indirectly improves the overall reliability and economy of electric power system.

[0022] Further, the limiting sleeve 401 is fixedly provided with protrusions 5 on both sides of the entrance of the movable through slot 402, and the end of the protrusion 5 in contact with the limiting rod 404 is provided with an arc chamfer; in operation, when the anti-misoperation mechanism 4 is unlocked during the opening and closing operation, the operator rotates the limiting cover 403, and since the limiting cover 403 is fixedly connected with the limiting rod 404, the limiting rod 404 rotates and moves towards the movable through slot 402, and when the limiting rod 404 gradually approaches the entrance of the movable through slot 402, it will first come into contact with the protrusion 5, which can give the operator a clear tactile feedback, prompting the operator to reach the key operation area near the movable through slot 402, then the operator continues to rotate the limiting cover 403, so that the limiting rod 404 moves along the edge of the protrusion 5 and passes through the first protrusion 5 to enter between the two protrusions 5, in this process, the arc chamfer at one end of the protrusion 5 plays a key role, its smooth curved surface can guide the limiting rod 404 to smoothly slide into the gap between the protrusions 5, effectively avoiding the situation that the operation is blocked due to a straight collision or jam, ensuring that the limiting rod 404 can accurately enter the movable through slot 402 under the action of a small external force, thereby smoothly completing the subsequent pressing operation to trigger the button action, the setting of the protrusion 5 significantly improves the accuracy and reliability of the anti-misoperation mechanism, the tactile prompt given by the protrusion 5 can improve the operator's perception accuracy of the operation position, further reducing the possibility of misoperation, making the operation process safer and more efficient, which helps the operator to quickly and accurately complete the opening and closing operation of the gas-filled cabinet, improving the operation efficiency and safety of the power system,

[0023] Further, the limiting cover 403 is provided with an indication 6; in operation, the indication 6 interacts with the operator in the form of intuitive text, when the operator faces the equipment and prepares to operate, the eyes will first capture the "closing" and "opening" indications on the limiting cover 403, and this clear text indication can effectively penetrate the interference of various complex operation environments, such as insufficient light, too many surrounding equipment, or high mental pressure of the operator, etc., so that the operator can still quickly focus on the correct operation process, avoiding the error operation caused by the confusion or uncertainty of the operation direction, and promoting the efficient and orderly development of power production and operation.

[0024] Further, the circumferential side of the limiting cover 403 is provided with a plurality of grooves 7; when the operator needs to rotate the limiting cover 403 during operation, the fingers contact the circumferential side of the limiting cover 403, and the grooves 7 change the contact friction force distribution and size between the fingers and the limiting cover 403; during the rotation operation, the fingers rotate along the profile of the grooves 7 to apply force, the grooves 7 make the rotation process more stable and accurate, reduce the rotation angle deviation or operation error caused by uneven force application or finger sliding, promote the efficient and safe development of power production and operation and maintenance, and provide strong support for the stable development of the power industry.
