Description

Technical Field

[0001] The utility model relates to a switch cabinet movable door interlocking device, in particular to a three-axis adjustable lower door interlocking structure and a switch cabinet. Background Art

[0002] The existing interlocking mechanism of switchgear is as follows: the cable compartment door can only be opened when the grounding switch is closed; it cannot be opened when the grounding switch is open. Furthermore, the grounding switch can only be operated when the cable compartment door is closed. If the door is not closed properly, the grounding switch cannot be operated. This creates an interlocking relationship between the grounding switch and the cable compartment door.

[0003] There are currently two ways to control (interlock) the grounding switch with the lower door. One is a hidden type, with an L-plate welded to the back of the lower door. The up and down movement of the grounding switch is interlocked with this L-plate. The disadvantage of this interlock is that the interlock is inside the lower door, making adjustment, assembly, and observation inconvenient. The other is an exposed type, with a square hole directly above the lower door. A round or square rod extends directly from the grounding switch to mate with this hole. However, due to various cumulative manufacturing errors, this fit is always unsatisfactory and misaligned, resulting in the need for adjustment based on actual conditions. Utility Model Content

[0037] refer to Figure 1 This embodiment provides a three-axis adjustable lower door interlock structure, primarily used to ensure the safety and reliability of switchgear 8. The structure comprises a mechanism body 1 and a lower door interlock 2. The lower door interlock 2 is assembled with a lower door interlock hole 4 to achieve door locking and unlocking functions. An interlock transition plate 3 is disposed between the mechanism body 1 and the lower door interlock 2. This interlock transition plate 3 not only serves as a connection but also enables three-axis adjustment via a first connecting structure 31 and a second connecting structure 32 disposed thereon.

[0038] The first connecting structure 31 and the second connecting structure 32 are connected to the mechanism body 1 and the lower door interlocking member 2 respectively (as shown in FIG. Figure 5 ), they have left and right and up and down adjustment space, so that the position of the interlocking transition plate 3 can be fine-tuned according to actual needs. This design greatly improves the adaptability and flexibility of the structure and can adapt to switch cabinet doors 8 of different sizes and shapes.

[0039] Furthermore, by providing a plurality of spacers 5 between the interlocking transition plate 3 and the mechanism body 1, the front-to-back distance between the two can be adjusted, further enhancing the structure's adjustability. This design allows the interlocking structure to be quickly adjusted to suit different installation environments and requirements without replacing any components.

[0040] The specific structural design is that in the first connecting structure 31, a transverse waist-shaped hole 33 is used (such as Figure 3 ), and securely fastened to the mechanism body 1 by means of a transverse waist-shaped hole 33, which engages with the first bolt. This transverse waist-shaped hole 33 is a transverse, elongated slot. This design allows the first bolt to move left and right within the slot, enabling left-right adjustment. This design not only provides flexible adjustment space but also enhances the stability and durability of the structure.

[0041] To further enhance adjustment flexibility, at least two transverse waist-shaped holes 33 are provided in the first connection structure 31. These transverse waist-shaped holes 33 are vertically spaced apart, making the connection between the interlocking transition plate 3 and the mechanism body 1 more stable while also providing more adjustment options. In this embodiment, there are two transverse waist-shaped holes 33.

[0042] The gasket 5 is placed between the first connecting structure 31 and the mechanism body 1. The gasket 5 is provided with a bolt hole 51 (such as Figure 4 ), assembled behind the transverse waist hole 33, and locked together with the mechanism body 1 by the first bolt. This design makes the gasket 5 not only play the role of adjusting the front and rear spacing distance, but also enhances the stability of the entire interlocking structure

[0043] In the second connection structure 32, a vertical waist-shaped hole 34 is provided (eg Figure 3 ), and the second bolt engages with the lower door interlock 2 through a vertical waist-shaped hole 34. The vertical waist-shaped hole 34 is a vertically elongated slot, allowing the second bolt to move up and down within the slot, thus enabling vertical adjustment. The vertical waist-shaped hole 34 also provides flexible adjustment space and, in conjunction with the horizontal waist-shaped hole 33 and the gasket 5, achieves three-axis adjustability.

[0044] To enhance adjustment flexibility, at least two vertical waist-shaped holes 34 are provided in the second connecting structure 32. These vertical waist-shaped holes 34 are vertically spaced and cooperate with the transverse waist-shaped holes 33 in the first connecting structure 31 to provide more adjustment options. In this embodiment, there are three vertical waist-shaped holes 34.

[0045] In this embodiment, the gasket 5 is 1.5 mm thick and is made of aluminum-zinc-coated sheet material, which offers excellent corrosion resistance and strength. The interlocking transition plate 3 is 3.0 mm thick galvanized sheet metal, ensuring structural strength and durability. The lower door interlock 2 is constructed of square steel with a cross-section of 10 mm x 8 mm, a size and shape that provides sufficient strength and stability.

[0046] In this embodiment, the mechanism body 1 involved is a grounding switch 6 (such as Figure 2 This design seamlessly integrates the lower door interlock structure with the functions of grounding switch 6. When grounding switch 6 is open, lower door interlock 2 moves downward, pressing cable compartment door 7 to secure it closed. When grounding switch 6 is closed, lower door interlock 2 moves upward, lifting cable compartment door 7 and allowing it to open. This design enhances operational convenience and safety. Furthermore, thanks to the adjustable structure, the square steel always fits perfectly within the square hole of the lower door, ensuring the IP4X rating of the entire cabinet, regardless of whether grounding switch 6 is closed or open.

[0047] The linkage structure of the lower door interlocking member 2 and the cable room door 7 is that the cable room door 7 includes a notch 71 (such as Figure 6-7 ), the lower door interlocking member 2 is provided with a slot 21 at one end away from the interlocking transition plate 3, and the slot 21 is inserted into the notch 71 (such as Figure 8 This design makes the connection between the lower door interlock 2 and the cable compartment door 7 more stable, and also simplifies the installation and removal process.

[0048] The lower door interlock structure provided in this embodiment can be assembled in the switch cabinet 8, thereby improving the safety and reliability of the switch cabinet 8. With this structure, the door of the switch cabinet 8 can be locked and unlocked more accurately and safely, reducing potential safety hazards during operation.

[0049] The lower door interlock structure provided in this embodiment uses a square steel with a cross-section of 10mm×8mm for the lower door interlock of the mechanism body 1. An interlocking transition plate 3 is added between the square steel and the mechanism body 1. The connection between this interlocking transition plate 3 and the mechanism body 1 is a left and right horizontal waist-shaped hole. A gasket 5 or a pad (to be adjusted front and back) can be added between the two. The connection with the square steel is a vertical waist-shaped hole up and down. In this way, during the actual assembly process, if the square steel and the lower door interlocking hole 4 are misaligned, whether left or right, front or back, or up and down, it will not affect the interlocking assembly, ensuring reliable interlocking and the IP4X rating of the entire cabinet. By adding an interlocking transition plate 3, this embodiment can achieve three-axis adjustable interlocking, ensuring interlocking reliability, and easily eliminating the IP4X rating of the entire cabinet.

[0050] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
