[0030] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0031] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0032] Reference Figures 1-5 This embodiment provides a protective mechanism, including,

[0033] The protective component 1 includes a protective box 11, a switch 12 installed inside the protective box 11, and a rotating assembly 13 installed outside the switch 12.

[0034] Auxiliary component 2 includes an indicator component 21 installed on the outside of the rotating assembly 13 and a locking component 22 installed inside the protective box 11;

[0035] The rotating assembly 13 is used to control the on / off state of the switch 12, the indicating assembly 21 is used to display the on / off state of the switch 12, and the locking assembly 22 is used to lock the rotating assembly 13. The protective box 11 and the rotating assembly 13 should be made of insulating material.

[0036] In use, the switch 12 is located inside the protective box 11. The operator can control the switch 12 to open or close by driving the rotating component 13 from the outside of the protective box 11. Thus, even if leakage occurs when the switch 12 is switched on or off, the operator will not be electrocuted because the protective box 11 and the rotating component 13 are made of insulating materials, thereby protecting the operator.

[0037] As one embodiment provided in this application, such as Figures 1-3 The protective box 11 includes a box body 111 and a protective door 112 that is rotatably connected to the outside of the box body 111.

[0038] The switch 12 includes a switch body 121 installed inside the protective box 11, and an operating handle 122 adapted to be installed inside the switch body 121.

[0039] The rotating assembly 13 includes a collar 131 sleeved on the outside of the operating handle 122, a first connecting rod 132 fixedly connected to the outside of the collar 131, a second connecting rod 133 fixedly connected to the outside of the first connecting rod 132, and a rotating rod 134 fixedly connected to the outside of the second connecting rod 133.

[0040] Rotating rod 134 is rotatably connected to the outside of protective box 11.

[0041] As attached Figure 3 As shown, during use, the operator can rotate the rotating rod 134 on the outer side of the box 111, which will cause the rotating rod 134 to drive the first connecting rod 132 to rotate via the second connecting rod 133. The first connecting rod 132 will then drive the operating handle 122 to rotate via the collar 131, thereby controlling the power supply to and from the switch body 121.

[0042] By controlling the lever 134 to control the power on and off of the switch body 121, it is possible to prevent personnel from directly contacting the switch body 121 and the operating handle 122, effectively preventing personnel from being electrocuted when switching power on and off.

[0043] As one embodiment provided in this application, such as Figures 1-4The indicator component 21 includes an anti-slip handle 211 fixedly connected to the outside of the rotating rod 134, a pointer 212 fixedly connected to the outside of the anti-slip handle 211, and an on indicator area 213 and an off indicator area 214 disposed on the outside of the housing 111. The on indicator area 213 and the off indicator area 214 can be distinguished by spraying different colored pigments, for example, green pigment is sprayed on the on indicator area 213 and red pigment is sprayed on the off indicator area 214.

[0044] Staff can rotate the lever 134 by turning the anti-slip handle 211, which can improve the staff's grip.

[0045] When the anti-slip handle 211 is rotated, the pointer 212 will also rotate synchronously. Thus, the operator can observe the position of the pointer 212 to determine whether the lever 134 has rotated to the on or off position of the switch body 121. That is, when the pointer 212 rotates to the on indicator area 213, it means that the switch body 121 is in the on state, and when the pointer 212 rotates to the off indicator area 214, it means that the switch body 121 is in the off state.

[0046] As one embodiment provided in this application, such as Figures 1-5 The locking assembly 22 includes a first circular groove 221, a first vertical groove 222, a second circular groove 223 and a second vertical groove 224 formed inside the housing 111, a large gear 225 fixedly connected to the outside of the rotating rod 134, a first rack 226 slidably connected inside the first vertical groove 222, a spring 227 slidably connected to the outside of the first rack 226, a small gear 228 rotatably connected inside the second circular groove 223, and a second rack 229 slidably connected inside the second vertical groove 224.

[0047] The large gear 225 is disposed inside the first circular groove 221, the first rack 226 meshes with the small gear 228, and the second rack 229 meshes with the small gear 228;

[0048] One end of the spring 227 is fixedly connected to the outside of the first rack 226, and the other end of the spring 227 is fixedly connected to the inside of the first vertical groove 222.

[0049] As attached Figure 5 As shown, when it is necessary to rotate the lever 134, the operator can press down the second rack 229, causing it to slide downwards inside the second vertical groove 224, which in turn drives the pinion 228 to rotate. The rotation of the pinion 228 causes the first rack 226 to slide upwards inside the first vertical groove 222, compressing the spring 227. When the first rack 226 slides upwards, its bottom end can disengage from the teeth of the large gear 225, allowing the large gear 225 to rotate. At this time, the locking assembly 22 is in the unlocked state, and the operator can rotate the lever 134.

[0050] When the lever 134 rotates to the open or closed position of the switch body 121, and the operator stops pressing the second rack 229, the first rack 226 will slide downwards under the restoring force of the spring 227. The bottom end of the first rack 226 will re-insert into the teeth of the large gear 225, causing the first rack 226 to drive the small gear 228 to rotate, thereby causing the small gear 228 to drive the second rack 229 to rise. At this time, the locking component 22 is in a locked state. The large gear 225 cannot rotate because it is jammed by the bottom end of the first rack 226. That is, the lever 134 cannot rotate, and the switch body 121 cannot switch between on and off states, preventing the operator from accidentally switching the power on or off.

[0051] In summary, through the cooperation of various components, the operator can switch the power supply of the switch body 121 without directly touching the operating handle 122, reducing the risk of electric shock. In addition, by setting the locking component 22, it can effectively prevent the operator from accidentally touching the switch body 121 and causing incorrect power supply switching, which could lead to abnormal power supply operation.

[0052] Reference Figure 1 This embodiment provides a power distribution cabinet, including a protective mechanism, and also includes,

[0053] The main structure 3 includes a distribution box 31 located outside the protection box 11, and a core component 32 installed inside the distribution box 31.

[0054] The distribution box 31 includes a distribution box body 311 and a door 312 rotatably connected to the outside of the distribution box body 311;

[0055] The box 111 is installed inside the main body 311 of the distribution box.

[0056] The core component 32 includes a mounting bracket 321 installed inside the distribution box body 311, and an air switch 322 installed outside the mounting bracket 321.

[0057] The air switch 322 is electrically connected to the switch body 121.

[0058] The mounting bracket 321 can be made of metal, possessing good strength and stability. It is fixed to the inner wall of the distribution box body 311 by bolts or other fasteners, providing stable support for the air switch 322. The number of air switches 322 can be configured according to actual power consumption needs. They are arranged and installed on the mounting bracket 321 for easy circuit switching control and overload / short circuit protection.

[0059] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways, as long as they do not depart from the scope of this utility model.
