[0021] Embodiment 1:

[0022] See also Figure 1 -Five-protection lock body 3, a protection mechanism for a five-protection lock in the present embodiment, comprises a magnetic adsorption ring 1, the middle part of the magnetic adsorption ring 1 is rotatably connected with a connecting bracket 11, two fixing components 2 are arranged inside the magnetic adsorption ring 1, a five-protection lock body 3 is arranged between the two fixing components 2, and the two fixing components 2 are used to fix the five-protection lock body 3; by providing the fixing components 2, it is convenient for the staff to install it with the five-protection lock body 3 during use, which effectively ensures its convenience during use; by providing the magnetic adsorption ring 1, it is convenient to connect it with the distribution cabinet or other power system outer box, and the staff can directly adsorb the magnetic adsorption ring 1 on the distribution cabinet during use, which effectively facilitates the staff to install it.

[0023] In order to achieve the effect of waterproofing and dustproofing the five-protection lock body 3, a protective cover 12 is arranged between the connecting bracket 11 and the magnetic adsorption ring 1 in this embodiment, and the protective cover 12 is used to protect the five-protection lock body 3; in actual use, the protective cover 12 is provided to enable the five-protection lock body 3 to have good protection during use, and can effectively prevent the five-protection lock body 3 from rusting inside due to water ingress during outdoor use, and at the same time, can prevent dust and other debris from entering the lock hole and causing it to malfunction.

[0024] By providing a mounting sleeve 21 on the fixing assembly 2, a connecting slide bar 22 is slidably connected in the mounting sleeve 21, one end of the connecting slide bar 22 located in the mounting sleeve 21 is fixedly connected to the connecting spring 2 and the five-proof lock body 3, the other end of the connecting spring 2 and the five-proof lock body 3 is fixedly connected to the inside of the mounting sleeve 21, and the other end of the connecting slide bar 22 is fixedly connected to the clamping plate 24, and a support platform 25 is provided on the clamping plate 24. This connection method can effectively facilitate the staff to connect it with the five-proof lock body 3, ensure its installation effect, and at the same time, can fix the five-proof lock body 3, and can ensure its stability after installation.

[0025] Embodiment 2:

[0026] See also Figure 1-Five-proof lock body 3, in order to achieve a good protective effect on the five-proof lock body 3, a plurality of support bones 1 five-proof lock bodies 3 are provided on the protective cover 12 in this embodiment, and the material of the support bones 1 five-proof lock body 3 is elastic steel. By providing a plurality of support bones 1 five-proof lock bodies 3 on the protective cover 12, it can provide a good supporting effect on the protective cover 12 during use. In the actual use process, the support bones 1 five-proof lock body 3 can prop up the protective cover 12 into an arc, and when rain falls on the protective cover 12, it can slide down. A control handle 14 is provided on the connecting bracket 11. It is convenient for the staff to pull the connecting bracket 11, which increases its convenience during use. By providing a first magnetic suction piece 15 on the connecting bracket 11 and a second magnetic suction piece 16 on the magnetic adsorption ring 1. During use, the connection effect between the connecting bracket 11 and the magnetic adsorption ring 1 can be achieved, ensuring that it can have better sealing during use and can facilitate the staff to control it. The material of the protective cover 12 is polyethylene polypropylene. By setting the protective cover 12 to be polyethylene polypropylene, it can have a good dustproof effect.

[0027] The working principle of the above embodiment is:

[0028] 1. During use, the staff can first adsorb the magnetic adsorption ring 1 on the distribution cabinet, and then pull the control handle 14 to drive the connecting bracket 11 to rotate on the magnetic adsorption ring 1. During the rotation of the connecting bracket 11, the protective cover 12 can be contracted, thereby leaking the internal five-proof lock body 3. Then the staff can push the two clamping plates 24 to both sides so that the five-proof lock body 3 can be located between the two clamping plates 24. At this time, the two clamping plates 24 can fix the five-proof lock body 3 under the action of the connecting spring 2 and the five-proof lock body 3, thereby achieving the installation effect between the whole and the five-proof lock body 3.

[0029] 2. When the five-protection lock body 3 needs to be protected, the staff can pull the control handle 14 again to make the connection bracket 11 rotate on the magnetic adsorption ring 1. During the rotation of the connection bracket 11, the protective cover 12 can be unfolded, and the support bone 1 and the five-protection lock body 3 can support the protective cover 12. When the connection bracket 11 continues to rotate until it fits with the magnetic adsorption ring 1, the first magnetic suction piece 15 and the second magnetic suction piece 16 will be attracted to each other, thereby achieving the effect of fixing the connection bracket 11. At this time, the protective cover 12 just completely covers the five-protection lock body 3, achieving a good sealing effect.
