[0002] With the continuous development of power systems, switchgear is being used more and more widely, which puts forward higher requirements for the installation efficiency of its cabinet doors. At the same time, in order to ensure the safety of workers, it is necessary to avoid dangerous situations such as working at heights and tools falling during the installation process. Therefore, there is a need for a switchgear cabinet door that is easy to install, which can reduce installation time and workload and reduce safety risks.

[0003] Switchgear requires regular maintenance and inspection during use. Easy installation and removal of the cabinet door allows staff to quickly enter the cabinet to inspect, repair, and replace parts.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments. Example 1:

[0018] Reference Figure 1-5This first embodiment of the present invention discloses a switch cabinet door structure that is easy to install and maintain, comprising: a switch cabinet 1 and a switch door 2, the switch door 2 being rotatably connected to the switch cabinet 1, a U-shaped fixing sleeve 3 being provided on the vertical surface of the switch cabinet 1, a plug-in device 4 being rotatably connected to the U-shaped fixing sleeve 3, the plug-in device 4 being fixedly connected to the switch door 2, a rectangular docking groove being provided on the vertical surface of the switch cabinet 1, a pair of L-shaped mounting plates being fixedly connected to the vertical surface of the U-shaped fixing sleeve 3, both of the pair of L-shaped mounting plates being fixedly mounted with the same arc-shaped outer shell 5, a rectangular limiting rod 6 being slidably connected to the upper and lower surfaces of the arc-shaped outer shell 5, and a pair of plug-in structures 7 being provided on the inner ring of the arc-shaped outer shell 5.

[0019] The rectangular limiting rod 6 on the lower surface has a rectangular piece running through it on the rod body of the arc-shaped outer shell 5. A tension spring is also provided on the upper surface of the rectangular piece, and the end of the tension spring away from the rectangular piece is connected to the lower surface of the arc-shaped outer shell 5.

[0020] The plug-in structure 7 includes: a circular tube 8, an arc-shaped block 9 fixedly connected to the cross section of the circular tube 8, an arc-shaped sleeve 10 fixedly connected to the outer ring of the arc-shaped block 9, an arc-shaped guide groove 11 opened on the outer ring of each pair of arc-shaped sleeves 10, a rectangular lifting groove opened on the vertical surface of each arc-shaped block 9, a pair of rectangular mating holes opened on the inner ring of the rectangular lifting groove, a rubber layer provided on the inner ring of the rectangular mating holes, a rectangular plate 12 slidably connected to the rectangular mating holes, and a spring piece 13 fixedly installed on the upper surface of the rectangular plate 12.

[0021] The rectangular lifting slot has a pair of T-shaped slots inside, and the inner rings of the pair of T-shaped slots are slidably connected to the rectangular lifting plate 14. The pair of arc-shaped guide slots 11 are connected to the same limiting ring 15. The upper surface of the rectangular lifting plate 14 is fixedly connected to the same conical push rod 16.

[0022] When the device is in use, because a rectangular docking groove is provided on the vertical surface of the switch cabinet 1, and a pair of L-shaped mounting plates are fixedly connected to the vertical surface of the U-shaped fixing sleeve 3, and the same arc-shaped outer shell 5 is fixedly installed on both of the L-shaped mounting plates, the cross section of the arc-shaped outer shell 5 is aligned with the rectangular docking groove and then inserted. Because a pair of guide rods are also provided on the vertical surface of the switch cabinet 1 (the guide rods align the U-shaped fixing sleeve 3), after the insertion is completed, it can be twisted directly. This is because the insertion structure 7 includes: a circular tube 8, an arc-shaped block 9 is fixedly connected to the cross section of the circular tube 8, an arc-shaped sleeve 10 is fixedly connected to the outer ring of the arc-shaped block 9, and an arc-shaped guide groove 11 is provided on the outer ring of both arc-shaped sleeves 10, and the rectangular limiting rod 6 is located in the inner ring of the guide groove 11.

[0023] When the torsion bar is rotated, the elliptical arc sleeve 10 will rotate, thereby pushing out the rectangular limiting rod 6 and finally inserting it into the insertion holes opened on the top and bottom surfaces inside the rectangular mating groove. After rotating 90 degrees (during the rotation process, because a rubber layer is provided at the intersection of the annular tube 8 and the U-shaped fixing sleeve 3, the manual rotation is kept within a certain range), the rectangular limiting rod 6 on the upper surface will descend a section under gravity, while the rectangular limiting rod 6 below will rebound under the action of the tension spring, thereby contacting the limiting ring 15 and temporarily locking the insertion structure 7. Example 2:

[0024] Reference Figure 4-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a sliding groove 17 is provided through the outer ring of the annular tube 8, and a T-shaped moving block 18 is slidably connected to the inner ring of a pair of sliding grooves 17. A pair of T-shaped moving blocks 18 are fixedly connected to the same moving plate, and a U-shaped plate 19 is fixedly installed on the upper surface of the T-shaped moving block 18.

[0025] A round rod is rotatably connected to the inner ring of the U-shaped plate 19. A lifting rod 20 is fitted onto the rod. A U-shaped sleeve 21 is rotatably connected to the end of the lifting rod 20 away from the U-shaped plate 19. The U-shaped sleeve 21 is connected through the rectangular lifting plate 14.

[0026] When using the device, first follow the steps in Example 1. When disassembly is required, first push the push rod that is fixedly connected to the same moving plate as the pair of T-shaped moving blocks 18. When the moving plate moves, the U-shaped plate 19 and the U-shaped sleeve 21 will move closer and closer, thereby changing the angle of the lifting rod 20. Finally, the rectangular lifting plate 14 will rise, thereby causing the conical push rod 16 to push out the rectangular limiting rod 6. Finally, the torsion rod can be rotated back to its original position.

[0027] The remaining structure is the same as that in Example 1.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
