[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Reference Figures 1-4 A ring mains enclosure for easy maintenance includes a enclosure body 1 and an enclosure door 2. The enclosure door 2 is rotatably connected to the enclosure body 1 via a pivot 5. The enclosure also includes:

[0029] The limiting sleeve 3 is fixedly connected to the side wall of the box 1;

[0030] The slide bar 303 is fixedly connected in the limiting cylinder 3;

[0031] The skateboard 302 is slidably connected to the slide bar 303;

[0032] Push rod 305 is fixedly connected to slide plate 302;

[0033] The first magnet 3051 is fixedly connected to the push rod 305, and the box door 2 is an iron door, so the first magnet 3051 and the box door 2 are attracted to each other.

[0034] A winding drum 501 is fixedly connected to the rotating shaft 5, and a pull rope 5011 is connected to the winding drum 501. The pull rope 5011 is fixedly connected to the slide plate 302.

[0035] When the staff performs maintenance work, they manually open the box door 2. The rotation of the box door 2 will drive the rotating shaft 5 to rotate synchronously. The rotation of the rotating shaft 5 will drive the winding drum 501 to rotate. At this time, the winding drum 501 will rewind and pull the pull rope 5011. The pull rope 5011 will then pull the sliding plate 302 to slide. The sliding plate 302 will push the push rod 305 to move. After the push rod 305 moves a certain distance, the second magnet 3021 will be attracted by the third magnet 304. When the box door 2 is fully opened, it will be 180° open. At this time, after the second magnet 3021 is attracted by the third magnet 304, the sliding plate 302 will slide again. When the second magnet 3021 and the third magnet 304 are attracted, the first magnet 3051 will be attracted to the box door 2. At this time, the box door 2 will be fixed under the attraction of the first magnet 3051, and the staff can then carry out maintenance.

[0036] This application opens the box door 2 and pulls the sliding plate 302 to slide, thereby pushing out the push rod 305 and the first magnet 3051. When the box door 2 is fully opened, the first magnet 3051 and the box door 2 are attracted to each other, and the box door 2 is fixed by the attraction of the first magnet 3051. This prevents the box door 2 from opening and closing back and forth during the maintenance process, thus solving the problem that the box door 2 is easily blown back and forth by the wind in the prior art. This also makes the box door 2 no longer affect the maintenance work of the staff and improves the maintenance efficiency.

[0037] In practical implementation, the pull rope 5011 uses a commercially available high abrasion-resistant elastic rope.

[0038] A second magnet 3021 is fixedly connected to the slide plate 302, and a third magnet 304 is fixedly connected to the limiting cylinder 3. The second magnet 3021 and the third magnet 304 attract each other.

[0039] A pull rod 3022 is fixedly connected to the skateboard 302, and a pull ring 4 is fixedly connected to the end of the pull rod 3022 away from the skateboard 302.

[0040] Reference Figure 3 After the maintenance is completed, the staff holds the door 2 with one hand and pulls the pull ring 4 outward with the other. When the staff pulls the pull ring 4, the second magnet 3021 will separate from the third magnet 304. At this time, the pull rod 3022 will pull the slide plate 302 to slide back to its original position. After the slide plate 302 slides a certain distance, the second magnet 3021 will be out of the attraction range of the third magnet 304. At this time, the slide plate 302 will automatically slide back to its original position under the reset pull of the tension spring 301.

[0041] Reference Figure 3 In practice, a tension spring 301 is fixedly connected to the slide plate 302, and the end of the tension spring 301 away from the slide plate 302 is fixedly connected to the inner wall of the limiting cylinder 3.

[0042] By means of the tension spring 301 installed on the slide plate 302, when the operator pulls the lever 3022 to reset the slide plate 302, the tension spring 301 can make the slide plate 302 slide back to its original position quickly.

[0043] Reference Figure 4 In specific implementation, a rubber ring 3052 is fixedly connected to the first magnet 3051.

[0044] Reference Figure 4 By using the rubber ring 3052 set on the first magnet 3051, the impact force when the door 2 attracts the first magnet 3051 can be effectively absorbed, thereby effectively preventing the door 2 from being easily damaged by repeated attraction between the door 2 and the first magnet 3051.

[0045] A guide wheel 6 is rotatably connected inside the housing 1, and the pull rope 5011 is attached to the side wall of the guide wheel 6.

[0046] Reference Figure 3 The guide wheel 6 set in the housing 1 makes the pull rope 5011 easier to pull and release smoothly.

[0047] The limiting cylinder 3 has an arc-shaped hole 306, the inner diameter of which is larger than the outer diameter of the pull rope 5011.

[0048] By setting the arc-shaped hole 306 on the limiting cylinder 3, the external corner friction of the limiting cylinder 3 on the pull rope 5011 can be effectively reduced, thereby improving the service life of the pull rope 5011.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
