Description

Technical Field

[0001] This utility model relates to the technical field of power distribution cabinets, and more particularly to a power distribution cabinet. Background Technology

[0002] As a key piece of equipment in power distribution systems, distribution cabinets are widely used in industrial, commercial, and residential fields. Their main function is to safely house and protect various electrical components, such as circuit breakers, switches, contactors, relays, electricity meters, and other control and monitoring devices. With the continuous growth of electricity demand and the increasing complexity of the power environment, distribution cabinets not only undertake the basic tasks of power distribution and control, but also play a crucial role in ensuring power supply reliability, improving system security, and realizing intelligent management. In modern buildings and industrial facilities, the design and configuration of distribution cabinets directly affect the operating efficiency and maintenance convenience of the entire power system; therefore, their structural rationality, protection level, and compatibility have become important considerations in engineering design.

[0003] Currently, most distribution cabinets on the market use a one-way door design during maintenance, which has obvious drawbacks. This design makes maintenance operations on the back of the electrical equipment inside the cabinet extremely cumbersome. Furthermore, during adjustment or maintenance, the cabinet door often shakes repeatedly due to wind or other external factors, which can easily interfere with the normal work of the user and reduce the overall effectiveness of the distribution cabinet.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a power distribution cabinet is proposed. Summary of the Invention

[0005] This utility model overcomes the shortcomings of the prior art and provides a power distribution cabinet.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a power distribution cabinet, comprising: a base, a cabinet body disposed on the top of the base, and a locking component disposed within the base;

[0007] The cabinet body is fixedly connected to the top of the base, and cabinet doors are rotatably connected to both sides of the cabinet body;

[0008] The locking assembly includes: a plurality of fixed rods, the tops of which are fixedly connected to the top inner wall of the base; a fixed plate fixedly connected to the bottom of which are fixed rods; a sleeve slidably connected to the outer circumference of which are fixed rods; an elastic unit provided at the bottom of the sleeve and the upper surface of the fixed plate; sliding grooves provided on both sides of the inner wall of the base; a locking plate slidably connected in the sliding groove; a locking slot provided at the bottom of the cabinet door; the locking plate engaging with the locking slot; and a first connecting rod fixedly connected between the outer circumference of the sleeve and the locking plate.

[0009] One of the sleeves has a transmission rod fixedly connected to its outer circumference. The inner wall of one side of the base has a through groove. One end of the transmission rod is located in the groove and is slidably connected. The transmission rod is fixedly connected to a transmission block.

[0010] Several mounting components are provided between the inner walls of both sides of the cabinet.

[0011] In a preferred embodiment of this utility model, one side of the transmission block is slidably connected to one side of the outer wall of the base.

[0012] In a preferred embodiment of this utility model, the transmission block covers the slide groove.

[0013] In a preferred embodiment of this utility model, the elastic unit is a spring, and the spring is located between the sleeve and the fixed plate.

[0014] In a preferred embodiment of this utility model, one end of the spring is fixedly connected to the bottom of the sleeve, and the bottom of the spring is fixedly connected to the upper surface of the fixing plate.

[0015] In a preferred embodiment of this utility model, the spring is sleeved on the outside of the fixed rod.

[0016] In a preferred embodiment of the present invention, the installation component includes: an installation plate and two clips disposed on the inner walls of both sides of the cabinet.

[0017] In a preferred embodiment of this utility model, the two locking blocks are fixedly connected to the inner walls of both sides of the cabinet, and the two ends of the mounting plate are respectively engaged with the two locking blocks.

[0018] In a preferred embodiment of this utility model, a plurality of through slots are provided on one side of the mounting plate.

[0019] In a preferred embodiment of this utility model, a second connecting rod is fixedly connected between the outer circumferential walls of two adjacent sleeves.

[0020] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0021] (1) This utility model provides a power distribution cabinet. By setting the locking component, the cabinet door can be automatically locked and limited. When the cabinet door is closed, the spring force pushes the sleeve to reset along the fixed rod. The first connecting rod drives the card plate to horizontally engage with the slot at the bottom of the cabinet door, forming a mechanical lock. When opening, you only need to step on the transmission block. The transmission rod drives the sleeve to compress the spring, which can make the card plate disengage from the slot. The linear motion can be converted into the horizontal displacement of the card plate, realizing the synchronous unlocking and locking of the two cabinet doors. A further effect is that it effectively prevents the cabinet door from accidentally shaking or closing during maintenance, which not only ensures operational safety but also extends the service life of the cabinet structure.

[0022] (2) This utility model provides a power distribution cabinet. The mounting plate is detachably connected to the inner wall of the cabinet by the two ends of the mounting plate. The through groove provides a regular channel for cable laying and can adjust the installation position according to the size of the equipment. This not only provides a foundation for the installation of electrical equipment, but also realizes the management of cables through the through groove. The direct effect is to optimize the utilization rate of the cabinet space and make the installation and maintenance of equipment more convenient. Compared with the rigid layout problem caused by the fixed mounting plate in the traditional power distribution cabinet, the device body is more adaptable. It further reduces the risk of failure caused by messy lines. At the same time, the heat dissipation design of the through groove indirectly improves the stability of equipment operation.

[0023] (3) This utility model provides a power distribution cabinet. The stability of the cabinet door ensured by the locking component provides an ideal environment for the function of the installation component. The layout of the installation component, in turn, supports efficient maintenance after the double cabinet doors are opened. When maintenance personnel unlock both cabinet doors simultaneously by stepping on the transmission block, they can quickly approach the equipment from both directions with the help of the adjustability of the mounting plate. At the same time, the through groove ensures the standardization of cable management. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] like Figure 1 As shown, a power distribution cabinet includes: a base 1, a cabinet 2 disposed on top of the base 1, and a locking component 5 disposed inside the base 1;

[0032] like Figures 1-3 As shown, the cabinet body 2 is fixedly connected to the top of the base 1, and cabinet doors 3 are rotatably connected to both sides of the cabinet body 2.

[0033] like Figures 3-4 As shown, the locking assembly 5 includes: a plurality of fixing rods 501, the top of each fixing rod 501 being fixedly connected to the top inner wall of the base 1, the bottom of each fixing rod 501 being fixedly connected to a fixing plate 511, the outer circumferential walls of each fixing rod 501 being slidably connected to a sleeve 502, the bottom of the sleeve 502 and the upper surface of the fixing plate 511 being provided with elastic units, the inner walls of both sides of the base 1 being provided with sliding grooves 507, the sliding grooves 507 being slidably connected to a locking plate 506, the bottom of the cabinet door 3 being provided with a locking groove 8, the locking plate 506 engaging with the locking groove 8, the outer circumferential walls of the sleeve 502 and the locking plate 506 being fixedly connected to a first connecting rod 504, and the outer circumferential walls of two adjacent sleeves 502 being fixedly connected to a second connecting rod 505.

[0034] One of the sleeves 502 has a transmission rod 510 fixedly connected to its outer circumference. A through groove 508 is provided on one side of the inner wall of the base 1. One end of the transmission rod 510 is located in the groove 508 and is slidably connected. A transmission block 509 is fixedly connected to the transmission rod 510. One side of the transmission block 509 is slidably connected to one side of the outer wall of the base 1. The transmission block 509 covers the groove 508.

[0035] The elastic unit is a spring 503, which is located between the sleeve 502 and the fixing plate 511. One end of the spring 503 is fixedly connected to the bottom of the sleeve 502, and the bottom of the spring 503 is fixedly connected to the upper surface of the fixing plate 511. The spring 503 is sleeved on the outside of the fixing rod 501.

[0036] It should be noted that in the locking assembly 5 of the distribution cabinet, the coordinated action of each component achieves an efficient door locking mechanism. The fixed rod 501 serves as the supporting base for the device body, and the sleeve 502 slides along the outer wall of the fixed rod 501 in conjunction with the spring 503 at the bottom to form an elastic unit.

[0037] When the cabinet door 3 is closed, the elastic force of the spring 503 pushes the sleeve 502 to reset, and the first connecting rod 504 drives the locking plate 506 to horizontally engage with the slot 8 at the bottom of the cabinet door 3, forming a mechanical lock. This ensures the firmness of the cabinet door 3 in the closed state. Its automatic reset feature effectively prevents accidental opening caused by vibration or external force. At the same time, the buffer setting of the spring 503 reduces the impact loss between components, further improving the synchronization and safety of operation.

[0038] The transmission rod 510 is fixedly connected to the sleeve 502, and forms an external operation interface with the transmission block 509 through the slide groove 508; when the transmission block 509 is stepped on, the transmission drives the sleeve 502 to compress the spring 503, and its movement is synchronously transmitted to the adjacent sleeve 502 through the second connecting rod 505 to realize multi-point coordinated action.

[0039] Under the guidance of the sliding groove 507, the card plate 506 disengages from the slot 8, completing the synchronous unlocking of the double cabinet doors 3, which simplifies the operation process. The combination of components significantly optimizes the practical efficiency of the power distribution cabinet. The spring 503 is sleeved on the outside of the fixed rod 501 to ensure the directional stability of the elastic movement, while the transmission block 509 covering the sliding groove 508 plays a dustproof protection role. The unmarked transmission block 509 is integrated with the outer shell of the base 1 and is not easily noticed by the uninformed person. It is a functional switch, which to a certain extent avoids the misoperation of non-professionals.

[0040] The locking mechanism complements the functionality of the installation components. When cabinet door 3 is unlocked by foot pedal, the double-opening structure allows personnel to approach the equipment from both the front and back.

[0041] like Figures 1-3 As shown, several installation components are provided between the inner walls of both sides of the cabinet 22. The installation components include: a mounting plate 66 and two locking blocks 44 provided on the inner walls of both sides of the cabinet 22. The two locking blocks 44 are fixedly connected to the inner walls of both sides of the cabinet 22 respectively. The two ends of the mounting plate 66 are respectively engaged with the two locking blocks 44. Several through slots 77 are provided on one side of the mounting plate 66.

[0042] It should be noted that the mounting plate 66 is connected to the clips 44 on the inner wall of the cabinet 22 at both ends, forming a stable support platform. This allows electrical equipment to be positioned according to actual needs, directly optimizing the utilization of the cabinet space. It can also provide a modular installation base for components of different sizes, avoiding the rigid layout problem caused by traditional fixed mounting plates 6.

[0043] The through-slot 7 can form a neat cable management channel, ensuring that the wire bundles are laid out and fixed in an orderly manner, fundamentally eliminating the risk of short circuits, overheating or signal interference caused by messy wiring.

[0044] When this utility model is in use, when the cabinet door 3 is opened, the operator steps on the transmission block 509, and the transmission block 509 drives the transmission rod 510 to move along the track of the slide groove 508. At this time, the transmission rod 510 drives the adjacent sleeve 502 to slide along the axial direction of the fixed rod 501 through a rigid connection. When the sleeve 502 moves, it synchronously compresses the bottom spring 503, and converts the linear motion into the horizontal displacement of the locking plate 506 through the first connecting rod 504, so that the locking plate 506 disengages from the locking groove 8 structure at the bottom of the cabinet door 3, and completes the synchronous release of the two cabinet doors 3.

[0045] When the cabinet door 3 is opened, the compressed spring 503 immediately pushes the sleeve 502 to reset, causing the locking plate 506 to re-enter the locking position. During this process, the sliding groove 507 guides the movement trajectory of the locking plate 506, ensuring that the locking plate 506 and the locking groove 8 remain separated.

[0046] During maintenance, the double-door structure 3 allows personnel to approach the equipment from both the front and back. The mounting plate 6 uses a through groove 7 on one side to neatly lay cables, while the cooperation between the clip 4 and the inner wall of the cabinet 2 provides a stable support foundation for the mounting plate 6.

[0047] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
