Description

Technical Field

[0001] This utility model relates to the field of disconnector switchgear, specifically to an electromagnetic lock device for the door of a DC manual disconnector switchgear. Background Technology

[0002] An electromagnetic lock for cabinet doors is a device that uses electromagnetic principles to lock and unlock doors. It is widely used in electrical distribution cabinets, communication cabinets, smart homes, office spaces, and medical equipment. Its core function is to generate magnetic force to attract doors when energized and release them when de-energized, thus achieving safe and convenient access control.

[0003] In summary, the existing door locks of disconnector switchgear have many drawbacks, which are summarized as follows:

[0004] Currently, the door lock uses an electromagnetic lock pull-driven baffle on one side to prevent accidental manual operation. However, because the baffle needs to move up and down, it cannot be fixed and must be connected to the electromagnetic lock for fixation. The baffle is directly attached to the inner door panel. Furthermore, the play generated during connection and movement can easily cause the baffle to abut against the inner ring of the operating hole and be pushed forward, resulting in baffle deformation and jamming. In case of accidental operation, if the baffle is not opened, the handle directly contacts and pushes against the baffle, causing the pushing force to be directly transmitted to the latch through the force on the baffle, which can easily cause latch deformation and damage to the electromagnetic lock. Figure 6 As shown. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electromagnetic lock device for the door of a DC manual disconnect switch cabinet, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0007] An electromagnetic lock device for a DC manual disconnect switch cabinet door includes a door body, a baffle body, a connecting rod, a pad, an electromagnetic lock, and a fixing structure. The baffle body and the pad are rotatably mounted on the fixing structure, with the pad positioned between the baffle body and the door body. The fixing structure is connected to the door body. The baffle body has a limiting groove. One end of the connecting rod is rotatably connected to the latch of the electromagnetic lock, and the other end is rotatably connected to the baffle body. The pad ensures that the baffle body maintains a gap with the door body when fixed. The baffle body also adopts a 45° limiting rotation structure instead of the original form of directly extending from the latch, which prevents it from being jammed or deformed by impact with the operating hole during operation. Even if the operator operates it incorrectly, the thrust generated by the handle directly contacting the baffle body that blocks the operating hole will be first buffered by the fixing structure, reducing the impact on the electromagnetic lock body structure.

[0008] Preferably, the fixing structure is a bolt.

[0009] Preferably, the connection between the fixing structure and the cabinet door body is a threaded connection.

[0010] Preferably, the cabinet door body is provided with a limiting post.

[0011] Preferably, the limiting post is inserted into the limiting groove.

[0012] Preferably, the cabinet door body is provided with an operating hole.

[0013] Preferably, the position of the operating hole is adapted to the baffle body.

[0014] Preferably, the electromagnetic lock is fixed to the cabinet door body.

[0015] Preferably, one end of the connecting rod is rotatably connected to the latch of the electromagnetic lock via a stop bolt, and the other end is also rotatably connected to the baffle body via a stop bolt.

[0016] Preferably, the cabinet door body is an inner door.

[0017] Compared with the prior art, this utility model discloses an electromagnetic lock device for the door of a DC manual disconnect switch cabinet, including a door body, a baffle body, a connecting rod, a pad, an electromagnetic lock, and a fixing structure. The six components work together to achieve their function. The pad ensures that the baffle body maintains a gap with the door body when it is fixed. The baffle body also adopts a 45° limited rotation structure instead of the original form that extends directly from the lock tongue. During operation, it will not be jammed or deformed by impact with the operating hole. Even if the operator operates it by mistake, the thrust generated by the handle directly contacting the baffle body that blocks the operating hole will be first absorbed and buffered by the fixing structure, reducing the impact on the electromagnetic lock body structure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] An electromagnetic lock device for the door of a DC manual disconnect switch cabinet includes a door body 1, a baffle body 2, a connecting rod 3, a pad 4, an electromagnetic lock 5, and a fixing structure 6. The baffle body 2 and the pad 4 are rotatably mounted on the fixing structure 6, and the pad 4 is positioned between the baffle body 2 and the door body 1. The fixing structure 6 is connected to the door body 1. The baffle body 2 is provided with a limiting groove 21. One end of the connecting rod 3 is rotatably connected to the locking tongue of the electromagnetic lock 5, and the other end is rotatably connected to the baffle body 2.

[0026] The fixing structure 6 is a bolt, and the fixing structure 6 is connected to the cabinet door body 1 by a threaded connection. The cabinet door body 1 is provided with a limiting post 11, which passes through the limiting groove 21. The cabinet door body 1 is provided with an operating hole 12, and the position of the operating hole 12 is adapted to the baffle body 2. The electromagnetic lock 5 is fixed on the cabinet door body 1. One end of the connecting rod 3 is rotatably connected to the locking tongue of the electromagnetic lock 5 through a stop bolt, and the other end is also rotatably connected to the baffle body 2 through a stop bolt. The cabinet door body 1 is the inner door of the manual disconnect switch cabinet, which completely isolates the manual disconnect switch cabinet and the live parts of the busbar from the outside of the cabinet. The cabinet door body 1 is provided with an operation hole 12. When the operation hole 12 is opened, the operation handle can be inserted through the operation hole 12. The limiting groove 21 makes the baffle body 2 rotate only 45° on the limiting post 11. Working mode: using the attraction force generated by the electromagnetic lock 5 when it is powered on, the locking tongue of the electromagnetic lock 5 pulls the connecting rod 3, thereby driving the baffle body 2 to rotate counterclockwise by 45°, exposing the operation hole 12 on the cabinet door body 1; when the electromagnetic lock 5 is de-powered, the locking tongue of the electromagnetic lock 5 pushes the connecting rod 3, thereby driving the baffle body 2 to rotate clockwise by 45°, blocking the operation hole 12 on the cabinet door body 1.
