Description

Technical Field

[0001] The invention relates to the technical field of interlocking devices, and in particular to a multifunctional cabinet door interlock. Background Art

[0002] In order to meet the "five protection" requirements, interlocks are usually set between the cable room door and the fuse room door, between the grounding switch and the cable room door, and between the grounding switch, cable room door and fuse room door to prevent accidental entry into the energized interval, protect personnel safety, and improve power reliability.

[0003] At present, the switch cabinets in the industry include central trolley cabinets, ring network cabinets and solid cabinets, etc., with great differences in structure, so the forms of interlocking are also very different, which results in uneven reliability. Since the interlocking must run through the interval or be directly set outside the cabinet, it is easy to cause the protection level to fail to meet the requirements, which poses a great safety hazard. Especially in some special solutions (such as load switch + fuse combination electrical solution, etc.), there is currently no technical solution that can simultaneously achieve interlocking between the grounding switch, cable compartment and fuse compartment.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the application and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Example

[0019] A multifunctional cabinet door interlock, such as Figures 1 to 3 As shown, it is installed between the cabinet door, cabinet body and door panel, and includes a lock body 1, a sliding structure, a pin shaft 3, a slider connecting plate 4 and a driving structure. The lock body 1 is installed on the cabinet body, and a sliding structure is arranged on the lock body 1. The sliding structure is connected to one end of the slider connecting plate 4, and the other end of the slider connecting plate 4 is detachably connected with a driving structure. The driving structure is connected to the door panel, and a connecting structure is detachably connected to the upper surface of the sliding structure. A limiting structure is arranged between the door panel and the sliding structure. When the door panel is installed, the door panel is pushed, and the driving structure is pushed to drive the slider connecting plate 4, the sliding structure, the connecting structure and the limiting structure to move upward. When the limiting structure is successfully engaged, the door panels and the door panels are interlocked. When the connecting structure moves up to block the grounding switch, the door panel and the grounding switch are interlocked.

[0020] The sliding structure includes a slide groove, which is installed on the lock body 1. A first slider 2 is arranged inside the slide groove. The first slider 2 is connected to the slider connecting plate 4. When the slider connecting plate 4 is pushed, the first slider 2 is also pushed to move inside the slide groove. The first slider 2 drives the connecting structure and the limiting structure to move for interlocking.

[0021] The inside of the slide slot is connected to the first slider 2 via a spring sheet 6, so that after the limiting structure is in place, the spring sheet 6 drives the first slider 2 to pop out and drive the limiting structure to engage.

[0022] The limiting structure includes a pin 3 and a limiting block. The limiting block is fixedly installed on the door panel. A limiting groove is arranged inside the limiting block. One end of the pin 3 is fixedly connected to the first slider 2. The other end of the pin 3 is arranged in the limiting groove. When the pin 3 is driven into the limiting groove, the spring sheet 6 pushes the first slider 2, driving the pin 3 to engage into the limiting groove of the limiting block, so that the door panel cannot be opened, and the two door panels are interlocked.

[0023] The driving structure is a slider adjustment rod 10, the upper end of the slider adjustment rod 10 is connected to the first slider 2, the lower end of the slider adjustment rod 10 is connected to the second slider 5, the second slider 5 is slidably connected to the cabinet, and the driving structure also includes a clamping plate 11, which is fixedly connected to the door panel. When the door panel is installed, it is pushed upward, and the clamping plate 11 is clamped on the second slider 5, so that the second slider 5 slides upward, driving the slider adjustment rod 10 and the first slider 2 to slide upward, thereby playing a driving role. Example

[0024] Based on the first embodiment, a multifunctional cabinet door interlocking implementation is provided: The connecting structure includes an upper interlocking plate 7 of the grounding switch and a lower interlocking plate 8 of the grounding switch. The lower interlocking plate 8 of the grounding switch is fixedly connected to the sliding structure. The lower interlocking plate 8 of the grounding switch is fixedly connected to the upper interlocking plate 7 of the grounding switch. The upper interlocking plate 7 of the grounding switch is connected to the grounding switch. A bushing 9 is arranged between the upper interlocking plate 7 of the grounding switch and the lower interlocking plate 8 of the grounding switch.

[0025] What is different from the first embodiment is that when the lower door panel is closed, the driving structure on the lower door panel will drive the pin shaft 3, the first slider 2, the lower interlock plate 8 of the grounding switch, the bushing 9 and the upper interlock plate 7 of the grounding switch to slide upward along the direction of the slide groove in the lock body 1. At this time, the grounding switch baffle connected to the grounding switch moves upward to block the grounding switch, and the operation of the grounding switch is not allowed, thereby realizing interlocking.

[0026] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only used to explain the relative position relationship, movement, etc. between the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0028] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
