[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] See attached document Figure 1 - Appendix Figure 4 The present invention provides a quick maintenance window structure for a high and low voltage switchgear, including an outer cabinet panel 1 of the switchgear, an outer shell 2 of the maintenance window embedded inside the outer cabinet panel 1, a body 3 of the maintenance window embedded inside the outer shell 2, and the body 3 of the maintenance window and the outer shell 2 of the maintenance window being connected by a hinge.

[0028] The installation mechanism is located inside the outer cabinet panel 1 of the switch cabinet. The installation mechanism is used to install and remove the outer shell 2 of the inspection window.

[0029] The installation mechanism includes multiple movable blocks 4, which are respectively fixedly sleeved on the outside of the inspection window housing 2, and each of the multiple movable blocks 4 has a threaded groove inside.

[0030] The mounting mechanism also includes multiple threaded rods 5, which are all embedded inside the outer cabinet plate 1 of the switch cabinet. The front ends of the multiple threaded rods 5 extend to the outside of the outer cabinet plate 1 of the switch cabinet and are movably connected to the outer cabinet plate 1 of the switch cabinet through rolling bearings. The multiple threaded rods 5 are respectively connected to multiple moving blocks 4 through threads.

[0031] In this embodiment, by having the user place multiple movable blocks 4 on the outside of multiple threaded rods 5 and then pull two lifting rods 14 in the opposite direction, the multiple threaded rods 5 can be rotated, thereby making the inspection window housing 2 tightly embedded into the switch cabinet outer panel 1.

[0032] To facilitate installation and disassembly, this device employs the following technical solution: A movable groove 6 is provided inside the outer panel 1 of the switchgear. The movable groove 6 is fitted onto the outside of multiple threaded rods 5. Multiple transmission gears 7 are embedded inside the movable groove 6, and are respectively fixedly fitted onto the outside of the multiple threaded rods 5. A connecting ring 8 is embedded inside the movable groove 6, and limit rings 9 are fixedly connected to both the front and rear sides of the connecting ring 8. The two limit rings 9 are respectively embedded inside the outer panel 1 of the switchgear and slide against the outer panel 1. A transmission gear ring 10 is embedded inside the movable groove 6, and the transmission gear ring 10 is fitted onto the multiple transmission gears 7. The outer side is connected to multiple transmission gears 7. Two connecting pipes 11 are embedded inside the movable groove 6. Both connecting pipes 11 are movably connected to the connecting ring 8 through hinges. Connecting rods 12 are provided on the outer side of both connecting pipes 11. The connecting pipes 11 and connecting rods 12 are slidably connected. Two positioning rods 13 are fixedly embedded inside the movable groove 6. The two positioning rods 13 are respectively embedded in the two connecting rods 12 and slide against the connecting rods 12. Lifting rods 14 are fixedly connected to the front side of both connecting rods 12. Two lifting grooves 15 are opened on the front side of the switch cabinet outer panel 1. The front ends of the two lifting rods 14 respectively pass through to the outer side of the two lifting grooves 15.

[0033] When the inspection window housing 2 needs to be disassembled, the user pulls the two lifting rods 14 in the opposite direction, causing multiple connecting rods 12 and connecting pipes 11 to move. The movement of connecting pipes 11 drives the connecting ring 8 to rotate, which in turn drives the transmission gear ring 10 to rotate. The rotation of the transmission gear ring 10 drives the transmission gear 7 and threaded rod 5 to rotate, and the rotation of multiple threaded rods 5 drives multiple moving blocks 4 to move, thereby causing the inspection window housing 2 to detach from the switch cabinet outer panel 1, achieving the effect of disassembly. Similarly, when a new inspection window housing 2 needs to be installed, the user pulls the two lifting rods 14 in the opposite direction again, causing the moving blocks 4 to be fitted onto the outside of the threaded rods 5, achieving the effect of installation.

[0034] In order to achieve the purpose of preventing loosening, the device adopts the following technical solution: movable blocks 16 are sleeved on the outer side of both lifting rods 14, and snap-fit ​​rods 17 are fixedly connected to the outer side of both movable blocks 16. Multiple snap-fit ​​grooves 18 are opened on the front side of the switch cabinet outer panel 1, and the snap-fit ​​rods 17 match the snap-fit ​​grooves 18.

[0035] When it is necessary to fix the position of the lifting rod 14, the user pushes the two movable blocks 16 backward, so that the locking rod 17 is embedded into the corresponding locking groove 18, thereby fixing the position of the movable block 16 and the lifting rod 14 and preventing the inspection window housing 2 from becoming loose.

[0036] The usage process of this utility model is as follows: The user places multiple movable blocks 4 around the outside of multiple threaded rods 5, and then pulls two lifting rods 14 in the opposite direction, causing the multiple threaded rods 5 to rotate. This allows the inspection window housing 2 to be tightly embedded inside the switch cabinet outer panel 1. When the inspection window housing 2 needs to be disassembled, the user pulls the two lifting rods 14 in the opposite direction, causing multiple connecting rods 12 and connecting pipes 11 to move. The movement of the connecting pipes 11 drives the connecting ring 8 to rotate, which in turn drives the transmission gear ring 10 to rotate. The rotation of the transmission gear ring 10 then drives the transmission gear 7 and the threaded rods 5 to rotate. Multiple threaded rods 5 rotate, causing multiple movable blocks 4 to move, thereby detaching the inspection window housing 2 from the switch cabinet outer panel 1, achieving the effect of disassembly. Similarly, when a new inspection window housing 2 needs to be installed, the user pulls the two lifting rods 14 in the opposite direction again, so that the movable blocks 4 are fitted onto the outside of the threaded rods 5, achieving the effect of installation. When the position of the lifting rods 14 needs to be fixed, the user pushes the two movable blocks 16 backward, so that the locking rods 17 are embedded into the corresponding locking grooves 18, thereby fixing the position of the movable blocks 16 and the lifting rods 14 and preventing the inspection window housing 2 from becoming loose.

[0037] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
