Description

Technical Field

[0001] This utility model relates to the field of low-voltage distribution cabinet technology, specifically a withdrawable low-voltage distribution cabinet. Background Technology

[0002] Low-voltage distribution cabinets play a crucial role in the operation and maintenance of power systems, responsible for the rational distribution and control of electrical energy. Traditional low-voltage distribution cabinets are mostly fixed structures with internal electrical components installed in a fixed position. When performing maintenance, replacing parts, or troubleshooting, workers need to operate in the narrow space inside the cabinet. This is not only difficult to operate, but also prone to safety accidents such as electric shock, and takes a long time, affecting the stability of the power supply.

[0003] While some early pull-out low-voltage switchgear improved maintenance convenience to some extent, they lacked smoothness in drawer operation. Jamming and wobbling during drawer removal can loosen internal electrical connections, affecting normal equipment operation and potentially damaging electrical components, increasing maintenance costs. Furthermore, the locking mechanism of traditional pull-out low-voltage switchgear often lacks effective safety measures. Non-professionals or unauthorized personnel may misoperate the locking mechanism, causing the drawer to be accidentally pulled out, disrupting the normal operation of the power system and creating safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a withdrawable low-voltage distribution cabinet, which solves the technical problem that the locking structure of traditional withdrawable low-voltage distribution cabinets usually lacks effective protective measures, and achieves the purpose of preventing non-professionals from operating it by means of a protective structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a withdrawable low-voltage distribution cabinet, comprising a distribution cabinet body, a cabinet door hinged to the front of the distribution cabinet body, a protective shell fixedly installed on the back of the distribution cabinet body, and locking holes equidistantly provided on both sides of the distribution cabinet body, and a withdrawable assembly provided inside the distribution cabinet body.

[0006] Preferably, the extraction assembly includes: telescopic components, equidistantly arranged inside the power distribution cabinet body; and locking components, arranged on both sides of the power distribution cabinet body.

[0007] Preferably, the telescopic component includes: a slide rail, symmetrically and equidistantly installed on both sides of the inner wall of the distribution cabinet body; a connecting outer cylinder, symmetrically and equidistantly installed on the back of the inner wall of the protective shell; and a wire outer cylinder, symmetrically and equidistantly installed on the back of the outer wall of the distribution cabinet body.

[0008] Preferably, the slide rail is internally slidably connected to a slide rod, and a power distribution drawer is fixedly installed between the slide rods. The power distribution drawer is internally provided with a functional module. A guide rod is fixedly installed internally in the connecting outer cylinder. A limiting ring is slidably sleeved on the outer wall of the guide rod. A connecting inner cylinder is fixedly installed on one side of the limiting ring.

[0009] The slide rail has a sliding rod inside. When it is necessary to inspect or replace the functional modules inside the power distribution drawer, the sliding rod can slide smoothly in the slide rail, providing stable track support for the movement of the power distribution drawer.

[0010] Preferably, a spring is sleeved on the outer wall of the guide rod, one end of the spring is fixedly connected to the connecting outer cylinder, and the other end of the spring is fixedly connected to the limiting ring. A limiting ring is slidably sleeved inside the outer cylinder of the conductor, and an inner cylinder of the conductor is fixedly installed on one side of the limiting ring. The other end of the inner cylinder of the conductor moves through one side of the inner wall of the outer cylinder of the conductor, the back of the outer wall of the distribution cabinet body, and extends to the back of the inner wall of the distribution cabinet body, and is connected to the distribution drawer.

[0011] The spring connects the outer cylinder and the limiting ring, and during the process of pulling out or pushing the drawer, it can maintain a tight connection and a relatively stable positional relationship between the various components.

[0012] Preferably, the engaging components include: engaging plates, symmetrically fixedly installed on both sides of the outer wall of the power distribution drawer; protective frames, symmetrically fixedly installed on both sides of the outer wall of the power distribution cabinet body; and U-shaped connecting plates, symmetrically and equidistantly installed on both sides of the outer wall of the power distribution cabinet body.

[0013] Preferably, the outer side of the locking plate is symmetrically provided with locking grooves, which are connected to locking holes. The U-shaped connecting plate is disposed inside the protective frame. A movable rod is slidably sleeved inside the U-shaped connecting plate. A pull plate is fixedly installed at one end of the movable rod, and a locking block is fixedly installed at the other end of the movable rod.

[0016] The connecting top frame, protective frame and other components form a stable protective frame structure, providing a reliable installation base for components such as electric guide rails and locking rods.

[0017] This utility model provides a withdrawable low-voltage distribution cabinet. It has the following advantages:

[0018] (1) This utility model is started by an electric guide rail, which drives the slide to slide on its outer wall. The movable plate at the bottom of the slide moves accordingly. The movable plate drives the baffle to move through the connecting vertical plate. The limiting plate on the baffle is disengaged from the locking rod, so as to protect the locking structure and prevent people other than the operator from using the locking structure.

[0019] (2) By pulling the pull plate outward, the movable rod slides in the U-shaped connecting plate, compressing the second spring, causing the locking block to exit from the locking hole and locking groove. The first spring rebounds, pushing the inner connecting cylinder to slide in the outer connecting cylinder. The first limiting ring slides on the guide rod, and at the same time the inner wire cylinder slides in the outer wire cylinder, realizing the smooth extraction of the power distribution drawer. At the same time, it drives the sliding rod to slide in the slide rail, achieving the effect of facilitating the extraction of the power distribution drawer from the power distribution cabinet.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0030] Based on the problem that the locking structure of traditional withdrawable low-voltage distribution cabinets often lacks effective protective measures, this utility model provides a preferred embodiment of a withdrawable low-voltage distribution cabinet, for example... Figure 1-5The diagram shows a pull-out low-voltage distribution cabinet, comprising a cabinet body 1, a cabinet door 2 hinged to the front of the cabinet body 1, a protective shell 3 fixedly installed on the back of the cabinet body 1, and equidistant locking holes on both sides of the cabinet body 1. A pull-out assembly 4 is provided inside the cabinet body 1, comprising: telescopic components 41 equidistantly arranged inside the cabinet body 1; locking components 42 arranged on both sides of the cabinet body 1; the telescopic components 41 comprising: slide rails 411 symmetrically and equidistantly installed on both sides of the inner wall of the cabinet body 1; connecting outer cylinders 416 symmetrically and equidistantly installed on the back of the inner wall of the protective shell 3; and wire outer cylinders 4112 symmetrically and equidistantly installed on the back of the outer wall of the cabinet body 1; slide rods 412 slidably connected inside the slide rails 411, and a distribution drawer 413 fixedly installed between the slide rods 412; a functional module 414 is provided inside the distribution drawer 413; and a guide rod 417 is fixedly installed inside the connecting outer cylinder 416. A limiting ring 418 is slidably sleeved on the outer wall of the guide rod 417. A connecting inner cylinder 415 is fixedly installed on one side of the limiting ring 418. The connecting inner cylinder 415 is slidably sleeved with the connecting outer cylinder 416. The other end of the connecting inner cylinder 415 movably passes through one side of the inner wall of the connecting outer cylinder 416, the back of the outer wall of the distribution cabinet body 1, and extends to the back of the inner wall of the distribution cabinet body 1, and is fixedly connected to the distribution drawer 413. A spring 419 is sleeved on the outer wall of the guide rod 417. One end of the wire outer cylinder 416 is fixedly connected to the connecting outer cylinder 416, and the other end of the spring 419 is fixedly connected to the limiting ring 418. The inner side of the wire outer cylinder 4112 is slidably fitted with the limiting ring 4113. The inner side of the limiting ring 4113 is fixedly installed with the wire inner cylinder 4111. The other end of the wire inner cylinder 4111 moves through one side of the inner wall of the wire outer cylinder 4112, the back of the outer wall of the distribution cabinet body 1, and extends to the back of the inner wall of the distribution cabinet body 1, and is connected to the distribution drawer 413.

[0031] Furthermore, in this embodiment, the spring 419 rebounds, pushing the inner connecting cylinder 415 to slide within the outer connecting cylinder 416, and the limiting ring 418 to slide on the guide rod 417. At the same time, the inner conductor cylinder 4111 slides within the outer conductor cylinder 4112, thus achieving the smooth extraction of the power distribution drawer 413 and simultaneously driving the slide rod 412 to slide within the slide rail 411. Example

[0032] Based on Embodiment 1, a preferred embodiment of the withdrawable low-voltage distribution cabinet provided by this utility model is as follows: Figure 1-5As shown: The engaging component 42 includes: engaging plates 421, symmetrically fixedly installed on both sides of the outer wall of the distribution drawer 413; protective frames 422, symmetrically fixedly installed on both sides of the outer wall of the distribution cabinet body 1; and U-shaped connecting plates 423, symmetrically and equidistantly installed on both sides of the outer wall of the distribution cabinet body 1. Engaging grooves are symmetrically opened on the outer side of the engaging plates 421, and the engaging grooves communicate with engaging holes. The U-shaped connecting plates 423 are located inside the protective frames 422. A movable rod 424 is slidably sleeved inside the U-shaped connecting plates 423. A pull plate 427 is fixedly installed at one end of the movable rod 424, and an engaging block 425 is fixedly installed at the other end of the movable rod 424. The engaging blocks 425 are respectively adapted to the engaging holes and engaging grooves. A second spring 426 is sleeved on the outer wall of the movable rod 424. One end of the second spring 426 is fixedly connected to the engaging block 425, and the other end of the second spring 426 is fixedly connected to the U-shaped connecting plate 423. A connecting top frame 4210 is fixedly installed on the top of the protective frame 422. An electric guide rail 428 is fixedly installed on the top of the inner wall of the connecting top frame 4210. A slide block 429 is slidably connected to the outer wall of the electric guide rail 428. A movable plate 4215 is fixedly installed at the bottom of the slide block 429. One side of the movable plate 4215 moves through one side of the inner wall of the connecting top frame 4210 and extends to one side of the outer wall of the connecting top frame 4210. A locking rod 4211 is fixedly installed on one side of the inner wall of the protective frame 422. A limit plate 4212 is locked to the outer wall of the locking rod 4211. A baffle 4213 is fixedly installed on the other side of the limit plate 4212. The other side of the baffle 4213 moves through the other side of the inner wall of the protective frame 422 and extends to the other side of the outer wall of the protective frame 422. A connecting vertical plate 4214 is fixedly installed on the other side. The top of the connecting vertical plate 4214 is fixedly connected to the bottom of the movable plate 4215.

[0033] Furthermore, in this embodiment, the electric guide rail 428 is activated, causing the slide block 429 to slide on its outer wall. The movable plate 4215 at the bottom of the slide block 429 moves accordingly. The movable plate 4215 drives the baffle 4213 to move through the connecting vertical plate 4214. The limiting plate 4212 on the baffle 4213 disengages from the locking rod 4211. At the same time, the pull plate 427 is pulled outward, and the movable rod 424 slides in the U-shaped connecting plate 423, compressing the second spring 426, causing the locking block 425 to exit from the locking hole and locking groove.

[0034] When the power distribution drawer 413 needs to be pulled out, the electric guide rail 428 is activated, causing the slide block 429 to slide on its outer wall. The movable plate 4215 at the bottom of the slide block 429 moves accordingly. The movable plate 4215 moves the baffle 4213 through the connecting vertical plate 4214. The limiting plate 4212 on the baffle 4213 disengages from the locking rod 4211. At the same time, the pull plate 427 is pulled outward, and the movable rod 424 slides in the U-shaped connecting plate 423, compressing the second spring 426, causing the locking block 425 to disengage from the locking hole and locking groove, thus releasing the engagement. The locking mechanism of the electrical drawer 413 is as follows: When the drawer 413 is not extended, spring 419 is in a compressed state. After the resistance is removed, spring 419 rebounds, pushing the inner connecting cylinder 415 to slide within the outer connecting cylinder 416. The limiting ring 418 slides on the guide rod 417, and simultaneously the inner wire cylinder 4111 slides within the outer wire cylinder 4112, achieving a smooth withdrawal of the electrical drawer 413. This also causes the slide rod 412 to slide within the slide rail 411. After use, the electrical drawer 413 is pushed back into the electrical cabinet body 1. Rod 412 slides in the reverse direction within slide rail 411, connecting inner cylinder 415 slides in the reverse direction within connecting outer cylinder 416, spring 419 gradually returns to its original state, and wire inner cylinder 4111 slides in the reverse direction within wire outer cylinder 4112. When the engaging groove on engaging plate 421 aligns with the engaging hole on the distribution cabinet body 1, pull plate 427 is released, spring 426 returns to its original state, pushing engaging block 425 through engaging hole and engaging groove, thus fixing distribution drawer 413. At the same time, electric guide rail 428 drives slide block 429 to move in the reverse direction, causing limit plate 4212 to move. The module is re-engaged on the locking rod 4211 to enhance the fixing effect. The power distribution drawer 413 is equipped with a functional module 414. When the power distribution drawer 413 is in the normal working position, the inner tube of the wire 4111 is connected to the power distribution drawer 413, which can realize the electrical connection between the functional module 414 and the external circuit, thereby completing the corresponding power distribution function. When the power distribution drawer 413 is pulled out, the inner tube of the wire 4111 slides in the outer tube of the wire 4112, still maintaining a certain connection with the external circuit, which facilitates the maintenance or replacement of the functional module 414.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
