Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a drawer with a padlock and a power distribution cabinet. Background Technology

[0002] Distribution cabinets with drawers (commonly known as withdrawable switchgear or drawer-type switchgear) are a type of cabinet widely used in low-voltage power distribution systems. Their main functional units (such as circuit breakers, contactors, fuse assemblies, and instrument units) are all installed in drawers that can be independently pulled out / inserted, facilitating maintenance, replacement, and testing, while also improving power supply reliability. When the drawer units of the distribution cabinet are used with the cabinet body, their connection status with the main circuit and control circuit of the cabinet is mainly defined by isolation positions, test positions, and connection positions. Figure 1 As shown, the drawer's outer door is equipped with a display instrument 1, a power indicator light 2, a circuit breaker indicator light 3, a circuit breaker handle 4, an observation window 5 for observing the drawer's position (isolation position, test position, and connection position), a rocker arm hole 6 for inserting a rocker arm, and a drawer handle 7. When using the drawer, first push the open drawer to the isolation position until it cannot be pushed any further. Then insert the rocker arm into the rocker arm hole 6 and rock the drawer to the test position and connection position respectively. Finally, use the circuit breaker handle 4 to open and close the drawer to complete the circuit breaker operation. The drawer does not have a padlock function, making it difficult to lock the drawer in the isolation position, test position, and connection position respectively. Therefore, when maintenance personnel go to the back of the cabinet or other parts for repairs, the drawer can be easily moved by others, potentially damaging the components inside and threatening the safety of the maintenance personnel. Therefore, such distribution cabinets often require the addition of a padlock structure to ensure the security of the distribution cabinet. Currently, the industry mainly replaces original drawers by purchasing drawers with padlocks. However, since drawers with padlocks cost more than twice as much as those without, and a single distribution cabinet often has multiple drawers, replacing the entire drawer would significantly increase the cost of the distribution cabinet. In addition, replacing drawers involves significant changes to the drawer structure, which is not conducive to standardized control of the distribution cabinet drawers. Utility Model Content

[0003] Therefore, it is necessary to address the above-mentioned shortcomings by providing a drawer and distribution cabinet with a padlock that can reduce costs and facilitate standardized control.

[0004] A drawer with a padlock includes a main body that is movably disposed inside a cabinet of a power distribution cabinet, and a connecting hole is provided on the front panel of the main body for inserting a drive rocker arm to drive the drawer to move inside the cabinet.

[0005] The panel has a first guide hole extending along the length of the panel next to the connecting hole; the drawer also includes a padlock assembly, which includes a support fixed to the back of the panel, a slider on the support facing away from the panel and slidable relative to the support along the length of the panel, and a padlock; the support has a first lug passing through the first guide hole, and a guide on the back of the support; the slider has a second guide hole that slides and limits with the guide, a through hole or notch corresponding to the connecting hole, a second lug passing through the first guide hole and located above the first lug on the upper part of the slider, a connector that cooperates with the structural components of the cabinet on the lower part of the slider, and the padlock passing through the first lug and the second lug and located on the front side of the panel.

[0006] In one embodiment, a handle is also fixed to the front of the panel.

[0007] In one embodiment, the padlock assembly further includes a connecting screw, a load-bearing member attached to the back of the panel and corresponding to the handle, the connecting screw passing sequentially through the load-bearing member, the panel and the handle to fix the load-bearing member and the handle to the panel; a limiting notch is provided on the load-bearing member, and the side of the slider away from the through hole or notch is slidably inserted into the limiting notch.

[0008] In one embodiment, the load-bearing member has an L-shaped cross-section and includes a vertical part fixedly connected to the panel and a horizontal part fixedly connected to the bottom end of the vertical part and perpendicular to the vertical part. The limiting notch is opened at the edge of the horizontal part.

[0009] In one embodiment, the padlock assembly further includes a positioning member fixed to the back of the panel and located below the load-bearing member, wherein the horizontal part of the load-bearing member has a positioning hole or positioning notch corresponding to the positioning member for the positioning member to pass through.

[0010] In one embodiment, the connector extends along the side of the slider facing away from the panel.

[0011] In one embodiment, the length of the second lug is greater than the length of the first lug.

[0012] In one embodiment, the guide includes two limiting posts arranged side by side and spaced apart on the back of the support, the line connecting the two limiting posts being parallel to the length direction of the second guide hole.

[0013] In one embodiment, the padlock assembly further includes a limiting plate located on the side of the slider facing away from the panel. The limiting plate has through holes corresponding to the second guide hole, and both limiting posts pass through the through holes and are fixedly connected to the limiting plate.

[0014] This utility model also discloses a power distribution cabinet, which includes the aforementioned drawer with a padlock.

[0015] This utility model discloses a drawer and distribution cabinet with a padlock. A support and slider are installed on one side of the back of the panel, and a padlock is installed on one side of the front of the panel. When the slider slides to the point where the connecting hole aligns with the through hole or notch, a rocker arm can be inserted into the connecting hole to drive the drawer within the distribution cabinet. When the slider slides to the point where the first lug aligns with the second lug, the padlock's locking rod passes through the first and second lugs and locks the drawer, thus locking it. Simultaneously, the connecting hole is blocked by the slider to prevent the rocker arm from being accidentally inserted into the connecting hole, which could damage the padlock assembly. This prevents unauthorized opening of the drawer by maintenance personnel while they are inspecting the back of the cabinet or other areas, thus avoiding security issues. Since the padlock assembly is installed on the panel, when modifying the drawer, only the panel and the padlock assembly on it need to be replaced to provide the drawer with padlock functionality, significantly reducing the cost of updating the distribution cabinet's functionality. The overall structure of the drawer changes very little, which is beneficial for standardized control of the distribution cabinet's drawers. Attached Figure Description

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Example 1

[0024] Please combine Figure 2-6 This utility model discloses a drawer with a padlock that reduces costs and facilitates standardized control. The drawer is inserted into the cabinet of a power distribution cabinet to achieve encapsulation and electrical isolation of electrical functional units. In this embodiment, the drawer includes a main body 100 movably disposed within the cabinet, a panel 200 fixed to the front side of the main body 100 and forming a receiving cavity with the main body 100, and electrical components 300 housed within the receiving cavity. The panel 200 on the front side of the main body 100 has a connecting hole 210 for inserting a drive rocker arm to drive the drawer to move within the cabinet. During the movement of the drawer within the cabinet, the drawer successively moves to the isolation position, the experimental position, and the connecting position. When the drawer is at the isolation position, the experimental position, and the connecting position, its position is locked by locking holes on the cabinet or the drawer main body 100 to prevent accidental operation. The electrical components 300 within the enclosure include a main circuit and a control circuit. When the drawer is pulled out to the isolation position, both the main circuit and control circuit of the electrical components 300 are isolated from the circuitry within the cabinet, providing safe electrical isolation and allowing for safe maintenance, repair, and replacement of the electrical components 300 within the drawer. When the drawer is pushed into the test position within the cabinet (partially pushed in, not fully pushed in), the main circuit is isolated from the cabinet circuitry, while the control circuit is connected to the cabinet circuitry. At this point, the function of the control circuit and the operation of the operating mechanism can be tested without load on the main circuit. For example, the circuit breaker can be closed / opened, indicator lights and relay actions can be checked for correctness, protection settings can be verified, operating logic can be simulated, and relay calibration can be performed. The equipment is only put into operation after ensuring its control function is normal, avoiding closing circuits with faults. Typically, the drawer is pushed inward from the isolation position to the first clearly marked stop / lock position. The mechanical interlock ensures that the control circuit can only be connected to the cabinet circuitry when the main circuit is disconnected. Once the drawer is fully pushed into the cabinet, it moves to the connection position. At this point, both the main circuit and the control circuit are connected to the cabinet's circuitry, and the drawer is in normal operating condition. The distribution cabinet can then operate under load and function normally for monitoring. The drawer function of the distribution cabinet is common knowledge in the industry, and its function and working principle will not be elaborated upon here.

[0025] A first guide hole 220 extending along the length of the panel 200 is provided on the side of the connecting hole 210. In this embodiment, it is agreed that... Figure 2 The left and right directions shown are the length directions of panel 200. Figure 2 The front-to-back direction shown is the thickness direction of panel 200. Figure 2The vertical direction shown is the height direction of panel 200. After the drawer is inserted into the cabinet, the side of panel 200 facing outwards is the front of panel 200, and the side of panel 200 located in the receiving cavity is the back of panel 200. The drawer also includes a padlock assembly 400, which includes a support member 410 fixed to the back of panel 200, a slider 420 disposed on the support member 410 facing away from panel 200 and slidable relative to support member 410 along the length of panel 200, and a padlock 430. The padlock 430 can be any commercially available padlock that can be installed on a drawer of a distribution cabinet. When in use, the padlock 430 is located on the front side of panel 200. In this embodiment, panel 200 and padlock assembly 400 together constitute a panel assembly.

[0026] The support member 410 is provided with a first lug 440 passing through the first guide hole 220. The first lug 440 has a first hanging hole 441. Since the support member 410 is fixed to the back of the panel 200, the position of the first lug 440 within the first guide hole 220 remains unchanged after the support member 410 is installed. A guide member 450 is provided on the back of the support member 410, which provides a limiting engagement portion between the support member 410 and the slider 420. The slider 420 has a second guide hole 421 that slides and engages with the guide member 450, and a through hole or notch 422 corresponding to the connecting hole 210. The second guide hole 421 passes through the guide member 450 and extends along the length of the panel 200. Through the sliding engagement between the second guide hole 421 and the guide member 450, the sliding path of the slider 420 relative to the support member 410 can be limited to prevent the slider 420 from wobbling relative to the support member 410. The upper part of the slider 420 is provided with a second lug 460 that passes through the first guide hole 220 and is located above the first lug 440. The second lug 460 has a second hanging hole 461. In this embodiment, both the first lug 440 and the second lug 460 extend in a direction perpendicular to the front of the panel 200, so as to reduce the difficulty of the first lug 440 and the second lug 460 passing through the first guide hole 220, while facilitating the hanging of the padlock 430 on the first lug 440 and the second lug 460. When the drawer is locked, the padlock 430 passes through the first lug 440 and the second lug 460 and is located on one side of the front of the panel. The lower part of the slider 420 is provided with a connector 470 that cooperates with the structural components of the cabinet. The connector 470 has three slots 471 that are sequentially distributed along the thickness direction of the panel 200. The three slots 471 can be selectively engaged with the structural components of the cabinet when the drawer is in the isolation position, the experimental position, and the connection position. Preferably, the connector 470 extends along the side of the slider 420 facing away from the panel 200.

[0027] In this embodiment, the first guide hole has a first position adjacent to the connecting hole 210 and a second position away from the connecting hole 210. The first lug 440 is always located in the second position within the first guide hole 220. When the second lug 460 moves to the first position within the first guide hole 220, the connecting hole 210 is connected to the through hole or notch 422. At this time, the three slots 471 on the connector 470 are separated from the cabinet of the distribution cabinet, the drawer is in an unlocked state, the connecting hole 210 is not blocked, and a rocker arm can be inserted to move the drawer, so that the drawer can be normally rocked into or out of the cabinet. When the second lug 460 moves to the second position within the first guide hole 220, the projections of the first lug 440 and the second lug 460 in the height direction of the panel 200 coincide. At this time, the first hanging hole 441 and the second hanging hole 461 correspond and connect. The locking bar of the padlock 430 passes through the first hanging hole 441 and the second hanging hole 461 in sequence, and one of the three slots 471 engages with the structural component on the power distribution cabinet, connecting the movable drawer to the cabinet. Thus, after locking the padlock 430, the drawer can no longer be moved, achieving the locking of the drawer to prevent it from being accidentally opened. Furthermore, the slider 420 at least covers a portion of the connecting hole 210. This prevents the external rocker arm from being accidentally inserted into the connecting hole 210, achieving the interlock between the padlock 430 and the rocker arm. This prevents the drawer from being rocked in or out without a key, and also protects the padlock assembly 400 from being damaged by the rocker arm. In this solution, since the padlock components 400 are all installed on the panel 200, and the size and cost of each part are small, only the panel components of the drawer need to be updated to enable the drawer to have a padlock function. There is no need to replace the other parts on the drawer (lockable push mechanism), which can reduce the functional update cost of the drawer and the power distribution cabinet. It can be used as an optional accessory for the drawer and is only configured for drawers that require padlocks in the market. The solution is flexible and has good compatibility.

[0028] The front of panel 200 also features a display instrument, power indicator light and circuit breaker indicator light, circuit breaker handle, and an observation window for viewing the drawer positions (isolation position, test position, and connection position). Furthermore, a handle 230 is fixed to the front of panel 200, providing a grip for maintenance personnel when pushing or pulling the drawer. Preferably, a handle 230 is located on each of the lower sides of the front of panel 200, allowing maintenance personnel to hold one handle 230 with each hand for smooth pushing or pulling of the drawer.

[0029] In one embodiment, the padlock assembly 400 further includes connecting screws and a load-bearing member 480 that is attached to the back of the panel 200 and corresponds to the handle 230. The connecting screws pass sequentially through the load-bearing member 480, the panel 200, and the handle 230 to fix the load-bearing member 480 and the handle 230 to the panel 200. In this embodiment, the handle 230 has a U-shaped structure. Each end of the handle 230 is fixedly connected to the load-bearing member 480 by a connecting screw that passes through the panel 200 and is inserted into the load-bearing member 480. Thus, while fixing the handle 230 and the load-bearing member 480 to the panel 200, it also indirectly achieves the mutual connection between the handle 230 and the load-bearing member 480. A limiting notch 481 is provided on the load-bearing member 480, and the side of the slider 420 away from the through hole or notch 422 is slidably inserted into the limiting notch 481. In this way, the first guidance of the slider 420 relative to the support member 410 is achieved by the cooperation between the second lug 460 and the first guide hole 220, the second guidance of the slider 420 relative to the support member 410 is achieved by the cooperation between the guide member 450 and the second guide hole 421, and the third guidance of the slider 420 relative to the support member 410 is achieved by the cooperation between the limiting notch 481 and the slider 420, thereby improving the smoothness and reliability of the slider 420 sliding. In addition, by setting a limiting notch 481, when the drawer is in the isolation position, experimental position, or connection position, the slider 420 is moved so that the slot 471 on the slider 420 engages with the structural component inside the cabinet. The side of the slider 420 away from the connection hole 210 is inserted into the limiting notch 481. When the operator pulls the drawer handle 230 by hand, the force exerted by the slider 420 on the inner wall of the limiting notch 481 can be transmitted to the load-bearing component 480. Since the load-bearing component 480 is fixedly connected to the handle 230, this force is transmitted to the handle 230, which allows the entire drawer to withstand a relatively large pulling force, ensuring the reliability of the drawer with the padlock.

[0030] Furthermore, in this embodiment, the cross-section of the load-bearing member 480 is L-shaped. The load-bearing member 480 includes a vertical part fixedly connected to the panel 200 and a horizontal part fixedly connected to the bottom end of the vertical part and perpendicular to the vertical part. A limiting notch 481 is formed at the edge of the horizontal part. The padlock assembly 400 also includes a positioning member 490 fixed to the back of the panel 200 and located below the load-bearing member 480. The horizontal part of the load-bearing member 480 has a positioning hole or positioning notch 482 corresponding to the positioning member 490 for the positioning member 490 to pass through. In this way, by setting the positioning member 490, the load-bearing member 480 can be quickly positioned when installed on the panel 200, so that the holes on the load-bearing member 480 are aligned with the holes on the panel 200 and the handle 230, thereby reducing the installation difficulty of the load-bearing member 480.

[0031] In one embodiment, the length of the second lug 460 is greater than the length of the first lug 440, meaning that the end of the second lug 460 protrudes beyond the end of the first lug 440. Thus, when the position of the slider 420 needs to be adjusted, the end of the second lug 460 can be pulled to move the entire slider 420 along the length of the panel 200, reducing the difficulty of adjusting the position of the slider 420. In this embodiment, the guide member 450 includes two limiting posts arranged side-by-side and spaced apart on the back of the support member 410. The line connecting the two limiting posts is parallel to the length direction of the second guide hole 421. By setting the two limiting posts side-by-side, the slider 420 is supported by the contact between the two limiting posts and the upper inner wall of the second guide hole 421, achieving stable support for the slider 420 and preventing the slider 420 from swaying or shaking due to uneven force.

[0032] Furthermore, the padlock assembly 400 also includes a limiting plate 401, which is located on the side of the slider 420 facing away from the panel 200. The limiting plate 401 has a through hole 402 corresponding to the second guide hole 421. Both limiting posts pass through the through hole 402 and are fixedly connected to the limiting plate 401. That is, the limiting plate 401 is fixedly connected to the support member 410 through the two limiting posts. The slider 420 is located in the area between the limiting plate 401 and the support member 410, and the slider 420 slides in the area between the limiting plate 401 and the support member 410 through the cooperation of the second guide hole 421 and the limiting post, which can prevent the slider 420 from falling off the limiting post. In this way, the position of the slider 420 along the thickness direction of the panel 200 can be limited, so that the slider 420 can only move along the length direction of the panel 200 under the action of external traction force. When the second lug 460 of the slider 420 moves to the second position, depending on the different positions of the drawer in the cabinet (isolation position, test position, and connection position), one of the three slots 471 engages with the structural components on the cabinet to limit the position of the drawer in the isolation position, test position, and connection position. In other words, through the padlock assembly 400 of this solution, the drawer can still be locked in the corresponding position by the connection between the slider 420 and the padlock and the engagement between the slider 420 and the cabinet structural components when it is in the isolation position, test position, or connection position. This prevents the drawer from moving in the isolation, test, and connection states. In this way, maintenance personnel can leave to the back of the cabinet or other places for maintenance after locking the drawer without worrying about others moving the drawer, thus ensuring the safety of maintenance personnel.

[0033] Example 2

[0034] This utility model also discloses a power distribution cabinet, which includes the aforementioned drawer with a padlock. The cabinet also includes a cabinet body, a main busbar system, vertical busbars, and a secondary wiring system. The cabinet body is internally divided into several vertical functional compartments by metal partitions. Each functional compartment includes a busbar compartment located at the upper rear or rear side of the cabinet to accommodate the horizontally arranged main and vertical busbars; a functional unit compartment located in the middle of the cabinet to accommodate each drawer; and a cable compartment located at the lower rear or bottom of the cabinet for connecting and inserting outgoing cables. Each functional unit compartment is further divided into multiple drawer unit compartments. The main busbar system is connected to adjacent cabinets via busbar connectors. Vertical busbars are led down from the main busbars and distributed at the rear of each drawer unit compartment, with fixed sockets installed at the ends of the vertical busbars for inserting the drawer's main circuit. The secondary wiring system includes fixed secondary sockets on the cabinet body (corresponding to each drawer unit compartment), terminal blocks, control busbars, connecting wires, etc., for connecting the drawer control circuits to external systems (such as PLCs, DCS, and instrument panels). In this embodiment, the cabinet, main busbar system, vertical busbar, and secondary wiring system of the distribution cabinet are the same as those commonly found in commercially available distribution cabinets. Their structure and working principle are common knowledge and will not be described in detail here. In this embodiment, the structure of the drawers installed inside the distribution cabinet is the same as that of the drawers in Embodiment 1. For details, please refer to the description of the drawers in Embodiment 1, which will not be repeated here.

[0035] The present invention relates to a drawer and distribution cabinet with a padlock. A support member 410 and a slider 420 are provided on the back side of the panel 200, and a padlock is provided on the front side of the panel 200. When the slider 420 slides to the first position where the second lug 460 is located, the slot 471 on the connector 470 disconnects from the cabinet body, and the connecting hole 210 communicates with the through hole or notch 422, allowing a rocker arm to be inserted into the connecting hole 210 and driving the drawer to move within the cabinet. When the slider 420 slides to the second position where the second lug 460 is located, the padlock's locking rod passes through the first hanging hole 441 and the second hanging hole 461 and locks the padlock. The slot 471 engages with the cabinet body to lock the drawer. Simultaneously, the connecting hole 210 is blocked by the slider 420 to prevent the rocker arm from being accidentally inserted into the connecting hole 210, thus avoiding damage to the padlock assembly 400. This prevents unauthorized opening of the drawer by maintenance personnel while they are inspecting the rear of the cabinet or other areas, thus preventing security issues. All padlock assemblies 400 are installed on the panel 200. When modifying the drawer, only the panel 200 and the padlock assemblies 400 on it need to be replaced to provide padlock functionality, significantly reducing the cost of updating the cabinet's functionality. The overall structure of the drawer changes very little, facilitating standardized control of the cabinet's drawers.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
