[0019] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0020] Refer to Figs. 1-2A grounding switch locking mechanism to prevent misoperation includes a connecting strap 4, a protective base 5 (installed on the operation panel of the incoming line cabinet, not shown in the figure), and a protective cover 3 sleeved on the protective base 5. The protective cover 3 can rotate horizontally along the protective base 5. One end of the connecting strap 4 is set on the outer wall of the protective base 5, and the other end is set with an installation ring 1 sleeved on the protective cover 3. A connecting strap 4 is provided between the protective cover 3 and the protective base 5 to connect the two together. When the protective cover 3 is opened for operation, the protective cover 3 can be pulled out. There is no need to place the protective cover 3 separately, which makes the operation more convenient and also prevents the problem of the protective cover 3 from being lost.

[0021] The protective base 5 and the protective cover 3 are preferably made of aluminum alloy, which ensures overall strength and has good corrosion resistance and waterproof performance, but this is not a limitation.

[0022] Furthermore, the protective cover 3 can rotate horizontally along the mounting ring 1. The outer circumference of the protective cover 3 is recessed inward to form an annular groove 31. The mounting ring 1 is embedded in the annular groove 31. Through the cooperation of the annular groove 31 and the mounting ring 1, the protective cover 3 can rotate along the direction of the mounting ring 1 while realizing the combined operation between the protective cover 3 and the mounting ring 1. This can better mitigate the damage from external forces, improve its protective performance, and make it less likely to be pried open or damaged.

[0023] Furthermore, the connecting strap 4 is made of a flexible material, which can connect the protective cover 3 and the protective base 5 without affecting the normal installation and removal of the protective cover 3. The specific material is not specified here, but can be plastic, metal, etc.

[0024] Furthermore, the protective cover 3 is provided with a lock cylinder 2 that can realize the functions of unlocking and locking. The protective cover 3 is detachably connected to the protective base 5 through the lock cylinder 2. The lock cylinder 2 is provided with a retractable limiting block 21. The inner wall of the protective base 5 is provided with a limiting groove 51 that cooperates with the limiting block 21. The protective cover 3 is engaged with the limiting groove 51 through the limiting block 21. The protective cover 3 has a circular cross-section and a groove with the same outer diameter as the protective base 5. The limiting groove 51 has an annular structure. In practice, the protective cover 3, with the lock cylinder 2 already installed, is inserted into the protective base 5 in the insertion / removal direction. When the limiting block 21 on the lock cylinder 2 engages with the limiting groove 51 of the protective base 5, the padlock function is completed. After the padlock function is completed, the protective cover 3 cannot move in the insertion / removal direction due to the mutual engagement between the limiting block 21 and the limiting groove 51, ensuring that the padlock function is always maintained and achieving the protective purpose. Furthermore, since the limiting groove 51 is a ring structure, when an external force is applied, the protective cover 3 will rotate around the protective base 5 to mitigate the damage. When it is necessary to open the protective cover 2, the key is inserted into the lock cylinder 2 to unlock it. At this time, the limiting block 21 retracts, and the engagement between the limiting block 21 and the limiting groove 51 is released, allowing the protective cover 2 to be pulled out from the protective base 5 in the insertion / removal direction, thus releasing the padlock function.

[0025] It should be mentioned that the extension and retraction of the limit block 21 (which can be understood as the lock tongue) driven by the lock cylinder 2 and the key is a technology that has already been implemented in existing lock bodies. The specific implementation method will not be elaborated here.

[0026] Furthermore, the connecting strip 4 is fixed to the outer wall of the protective base 5 by a riveting process. Of course, the connecting strip 4 can also be fixed by means such as screws or adhesive, which is not limited here.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
