Description

Technical Field

[0001] This application relates to the technical field of power distribution cabinet locking, and in particular to a safety locking device for power distribution cabinets. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final stage equipment in the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits.

[0003] Chinese patent website discloses a safety locking device for a power distribution cabinet, publication number CN220487350U. It includes a power distribution cabinet body, a rotating cabinet door mounted on the cabinet body, limit claws mounted on the rotating cabinet door, limit buckles mounted on the power distribution cabinet body, a moving groove on the rotating cabinet door, a safety locking structure inside the moving groove, and a locking rod installed inside the power distribution cabinet body. The locking rod cooperates with the safety locking structure. This utility model, through the cooperation of the installed safety locking structure and the locking rod, allows for convenient locking and unlocking from the outside of the power distribution cabinet. The locking operation is performed through both rotation and pulling methods via the cooperation of the rotating locking component and the moving groove, simplifying the locking operation while improving locking safety and increasing the efficiency of the power distribution cabinet.

[0004] The solution also has the following problems: when opening the cabinet door, the two sets of locking mechanisms at the top and bottom of the cabinet door need to be rotated separately for control, which is cumbersome and inconvenient to operate and cannot be controlled quickly to open and close, thus having certain drawbacks.

[0005] Therefore, in order to solve the above problems, this application provides a safety locking device for a power distribution cabinet. Utility Model Content

[0006] The purpose of this utility model is to provide a safety locking device for power distribution cabinets to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a safety locking device for a power distribution cabinet, comprising a power distribution cabinet, a cabinet door installed on the wider side of the external side of the power distribution cabinet, fixing blocks symmetrically installed on the external side of the power distribution cabinet at the top and bottom edges of the cabinet door, limiting holes being formed on the external side of the fixing blocks, an equipment frame installed on the external side of the cabinet door at one end of the door opening, a cavity being formed inside the equipment frame, a rotating rod installed at the center of the inner sidewall of the cavity, a rotating block installed on the outer ring surface of the rotating rod inside the cavity, connecting blocks symmetrically installed at both ends of the external side of the rotating blocks, a limiting rod installed on the end of the connecting block away from the rotating block, and limiting blocks installed on the external side of the limiting rod on the inner sidewall of the cavity.

[0008] Preferably, one end of the rotating rod is rotatably connected to the inner wall of the cavity, and the end of the rotating rod away from the cavity extends through to the outside of the equipment frame and is equipped with a handle.

[0009] Preferably, both ends of the rotating block are rotatably connected to the two connecting blocks, and the ends of the two connecting blocks away from the rotating block are rotatably connected to the ends of the limiting rod.

[0010] Preferably, the outer ring size of the limiting rod is adapted to the inner wall size of the limiting hole, and one end of the limiting rod passes through the limiting block and then through the equipment frame to extend to its outside and into the inside of the limiting hole.

[0011] Preferably, a sleeve is installed on the outer side of the device frame and outside the rotating rod. A pin hole is opened at the top of the outer side of the sleeve. A pin rod is provided inside the pin hole. One end of the pin rod is connected to the inside of the pin hole and extends into the inside of the rotating rod. When the limiting rod is fully connected to the inside of the limiting hole, the pin hole coincides with the interface on the rotating rod.

[0012] Preferably, a handle is installed at one edge of the outer side of the device frame.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This safety locking device for a power distribution cabinet allows for the rotation of a rotating rod by turning a handle. The rotating rod's rotation causes a rotating block to rotate, which in turn moves a corresponding limit rod via two connecting blocks. This securely locks the cabinet door to the power distribution cabinet. A pin is inserted through a pin hole and extends into the rotating rod, thus limiting and fixing the rotating rod inside the sleeve. This prevents the handle from automatically reversing, which could cause the limit rod to disengage from the limit hole and prevent the cabinet door from locking. This device achieves quick and safe locking of the cabinet door and is easy to operate. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0022] A safety locking device for a power distribution cabinet, as described in the following example. Figure 1 , Figure 2 and Figure 3 The system includes a distribution cabinet 1, a cabinet door 2 installed on the wider side of the distribution cabinet 1, fixing blocks 3 symmetrically installed on the outside of the distribution cabinet 1 and at the top and bottom edges of the cabinet door 2, limiting holes 301 are opened on the outside of the fixing blocks 3, an equipment frame 4 is installed on the outside of the cabinet door 2 and at the opening end, a cavity 401 is opened inside the equipment frame 4, a rotating rod 5 is installed at the center of the inner side wall of the cavity 401, a rotating block 6 is installed on the outer ring surface of the rotating rod 5 and inside the cavity 401, connecting blocks 7 are symmetrically installed at both ends of the outside of the rotating block 6, a limiting rod 8 is installed at the end of the connecting block 7 away from the rotating block 6, and limiting blocks 9 are installed on the outside of the limiting rod 8 and on the inner side wall of the cavity 401.

[0023] Reference Figure 4 and Figure 5 One end of the rotating rod 5 is rotatably connected to the inner wall of the cavity 401, and the end of the rotating rod 5 away from the cavity 401 extends through to the outside of the equipment frame 4 and is equipped with a handle 10, thereby ensuring that the rotating rod 5 can be driven to rotate by rotating the handle 10.

[0024] Reference Figure 1 - Figure 5 Both ends of the rotating block 6 are rotatably connected to the two connecting blocks 7, and the ends of the two connecting blocks 7 away from the rotating block 6 are rotatably connected to the ends of the limiting rods 8. When the rotating rod 5 rotates, it drives the rotating block 6 to rotate. When the rotating block 6 rotates, it can drive the corresponding limiting rods 8 to move through the two connecting blocks 7.

[0025] Reference Figure 1 , Figure 2 and Figure 3The outer ring size of the limiting rod 8 is adapted to the inner wall size of the limiting hole 301. One end of the limiting rod 8 passes through the limiting block 9 and then through the equipment frame 4 to extend to its outside and into the inside of the limiting hole 301. The sliding of the limiting rod 8 inside the limiting block 9 increases the stability of the movement of the limiting rod 8. When the limiting rod 8 moves, one end is simultaneously connected to the inside of the limiting hole 301, thereby fixing the cabinet door 2 on the power distribution cabinet 1 and safely locking the cabinet door 2.

[0026] Reference Figure 4 and Figure 5 A sleeve 11 is installed on the outer side of the equipment frame 4 and outside the rotating rod 5. A pin hole 1101 is opened at the top of the sleeve 11. A pin rod 12 is provided inside the pin hole 1101. The bottom end of the pin rod 12 is inserted into the pin hole 1101 and extends into the rotating rod 5. When the limiting rod 8 is fully inserted into the limiting hole 301, the pin hole 1101 coincides with the interface on the rotating rod 5. Then the pin rod 12 is inserted along the pin hole 1101 and extends into the rotating rod 5, thereby limiting and fixing the rotating rod 5 inside the sleeve 11, preventing the handle 10 from automatically reversing and causing the limiting rod 8 to disengage from the limiting hole 301, thus preventing the cabinet door 2 from being locked.

[0027] Reference Figure 2 and Figure 4 A handle 13 is installed on one edge of the outer side of the equipment frame 4, which facilitates the opening and closing of the cabinet door 2.

[0028] The implementation principle of the safety locking device for a power distribution cabinet in this embodiment is as follows: When using the power distribution cabinet, the cabinet door 2 can be opened and closed easily by gripping the handle 13. By rotating the handle 10, the rotating rod 5 can be driven to rotate. When the rotating rod 5 rotates, it drives the rotating block 6 to rotate. When the rotating block 6 rotates, it can drive the corresponding limiting rod 8 to move through the two connecting blocks 7. The sliding of the limiting rod 8 inside the limiting block 9 increases the stability of the movement of the limiting rod 8. When the limiting rod 8 moves, one end is simultaneously connected to the inner end of the limiting hole 301. The cabinet door 2 is fixed to the distribution cabinet 1 and locked securely. When the limit rod 8 is fully inserted into the limit hole 301, the pin hole 1101 coincides with the interface on the rotating rod 5. Then, the pin rod 12 is inserted along the pin hole 1101 and extends into the rotating rod 5, thereby limiting and fixing the rotating rod 5 inside the sleeve 11. This prevents the handle 10 from automatically reversing, causing the limit rod 8 to disengage from the limit hole 301 and thus preventing the cabinet door 2 from being locked. This achieves quick and safe locking of the cabinet door 2 and is easy to operate.
