Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a complete set of power equipment cabinets and cabinet door interlocking devices. Background Technology

[0002] Complete sets of power equipment cabinets, including switch cabinets, outgoing line cabinets, ring main units, etc., are conventionally designed with inspection doors on the back. To prevent operators from accidentally touching live parts, the live parts and switch parts are often set up in two cabinets, one above the other. The two cabinet doors are designed so that the lower cabinet door covers part of the upper cabinet door. This achieves the purpose of preventing the upper cabinet door from being opened and the live parts from being opened without opening the lower cabinet door and turning off the switch, thus preventing operators from directly touching live parts when the power is on.

[0003] However, in the above design, when the cabinet door is closed, the lower cabinet door presses against part of the upper cabinet door. Since the cabinet door has a certain thickness, when both the upper and lower cabinet doors are open, the two cabinet doors are in a space-crossing state, which makes them prone to collisions / bumps. In addition, the upper cabinet door cannot be fully opened, which is also inconvenient for operators to inspect the inside of the cabinet. Utility Model Content

[0004] To solve the above problems, the purpose of this utility model is to provide a complete set of power equipment cabinets and cabinet door interlocking devices. While ensuring that the upper and lower cabinet doors do not press against each other, the cabinet door interlocking device ensures that the upper cabinet door can only be opened after the lower cabinet door is opened. This prevents operators from accidentally touching live parts and also prevents cross collisions when both cabinet doors are opened at the same time, making it convenient for operators to carry out maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] In the first aspect, this novel experimental invention provides a complete set of power equipment cabinets, including a cabinet body. The back of the cabinet body is provided with an upper cabinet door and a lower cabinet door, which are located in the same plane. The cabinet body is provided with a cabinet door interlocking device, which includes a connecting rod, a first latching member, and a second latching member. The connecting rod includes a first connecting rod and a second connecting rod. The upper and lower ends of the first connecting rod and the second connecting rod are connected by a first roller shaft and a second roller shaft, respectively, and the first connecting rod and the second connecting rod slide up and down relative to the cabinet body. The first latching member is located on the inner side of the upper cabinet door, and the second latching member is located on the inner side of the lower cabinet door. The first latching member is used to latch with the first roller shaft, and the second latching member is used to latch with the second roller shaft.

[0007] In conjunction with the first aspect, optionally, one side of both the upper cabinet door and the lower cabinet door is hinged to the cabinet body.

[0008] In conjunction with the first aspect, optionally, the surfaces of the first roller and the second roller are provided with anti-slip threads.

[0011] Secondly, this utility model provides a cabinet door interlocking device, including a connecting rod, a first locking member, and a second locking member. The connecting rod includes a first connecting rod and a second connecting rod. The upper and lower ends of the first connecting rod and the second connecting rod are connected by a first roller shaft and a second roller shaft, respectively. The first connecting rod and the second connecting rod slide up and down relative to the cabinet body. The first locking member is disposed on the inner side of the upper cabinet door, and the second locking member is disposed on the inner side of the lower cabinet door. The first locking member is used to engage with the first roller shaft, and the second locking member is used to engage with the second roller shaft.

[0012] In conjunction with the second aspect, optionally, the surfaces of the first roller and the second roller are provided with anti-slip threads.

[0013] In conjunction with the second aspect, optionally, a first connector and a second connector are provided on the inner side of the cabinet, the first link and the second link are slidably connected to the first connector and the second connector, and a connecting shaft is also provided between the first link and the second link, and the first connector and the connecting shaft are connected by a spring.

[0014] In conjunction with the second aspect, optionally, the cabinet is provided with a first opening and a second opening, the first snap-fit ​​component is snapped into the first roller shaft after passing through the first opening, and the second snap-fit ​​component is snapped into the second roller shaft after passing through the second opening.

[0015] In conjunction with the second aspect, optionally, the first snap-fit ​​component has a first snap-fit ​​opening, which is zigzag-shaped, and the second snap-fit ​​component has a second snap-fit ​​opening, which is diagonal-shaped.

[0016] The beneficial effects of this utility model are as follows: While ensuring that the upper and lower cabinet doors do not press against each other, a cabinet door interlocking device is installed. When the lower cabinet door gradually closes, the second locking member engages with the second roller shaft, pulling the first and second connecting rods downward relative to the cabinet body, causing the first locking member to engage with the first roller shaft. When the lower cabinet door gradually opens, the first and second connecting rods slide upward relative to the cabinet body, and the first roller shaft ejects the first locking member, allowing the upper cabinet door to open. This achieves the goal of allowing the upper cabinet door to open only after the lower cabinet door is opened. This prevents operators from accidentally touching live parts and also prevents cross-collision when both cabinet doors are opened simultaneously, facilitating maintenance by operators.
