Description

Technical Field

[0001] The utility model belongs to the technical field of switch cabinets and relates to a switch cabinet movable door interlocking device. Background Art

[0002] Switch cabinets have been used in my country's power industry for many years, and their application scope is becoming more and more extensive. The valve interlocking mechanism device is a component of the removable AC metal-enclosed switchgear and control equipment. It has two convertible positions. In order to avoid the incoming and outgoing static contacts in the circuit breaker room being energized during maintenance and endangering the personal safety of maintenance personnel, when the moving contact of the trolley is pushed in, the valve opens, and when the moving contact of the trolley is pulled out, the valve closes, thereby shielding the incoming and outgoing static contacts and isolating the energized contact box to ensure the safety of maintenance personnel entering the cabinet for maintenance work.

[0003] When the existing switch cabinet door interlocking device is in use, the movable rod has poor stability during movement and is prone to deviation. Summary of the Invention

[0004] The purpose of the utility model is to provide a switch cabinet door interlocking device to solve the above problems.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A switch cabinet door interlocking device is characterized in that it includes an upper door and a lower door, and a sliding shell is formed on both sides of the upper door and the lower door. A first movable rod and a second movable rod are arranged in the sliding shell, the first movable rod is located on the same side of the upper door and the lower door, and the second movable rod is located on the same side of the upper door and the lower door. A sliding groove is provided in the sliding shell, and the setting direction of the sliding groove is consistent with the setting direction of the first movable rod and the second movable rod. An embedded groove is provided in the sliding groove, and a ball is provided in the embedded groove. The ball is arranged in the embedded groove through a connecting rod, and a plurality of balls are provided and distributed in the embedded groove.

[0007] The utility model is further provided that the balls are evenly distributed in the embedded groove.

[0008] The present invention is further provided with a bracket plate on the first movable rod and the second movable rod, and the bracket plate is arranged on the non-moving side of the upper valve and the lower valve.

[0009] The utility model is further provided with a limit pin on one side of the bracket plate close to the upper valve.

[0010] The beneficial effects of the present invention are as follows: the present invention provides sliding shells on both sides of the upper valve and the lower valve to realize the movement of the upper and lower valves, thereby improving the stability during sliding; in addition, balls are provided in the sliding grooves in the sliding shells, which can ensure that the upper and lower valves slide more smoothly.

[0020] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0021] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system.
