Description

Technical Field

[0001] This utility model belongs to the field of power distribution equipment technology, and in particular relates to a low-voltage integrated distribution box that is easy to maintain. Background Technology

[0002] Low-voltage integrated distribution boxes are important power distribution equipment in power systems and are widely used in various power consumption scenarios. They typically contain electrical components such as circuit breakers, contactors, and relays, and the stable operation of these components directly affects the reliability of the power supply system.

[0003] However, in existing low-voltage integrated distribution boxes, electrical components are mostly directly fixed to the inner wall of the box or to fixed brackets. When maintenance is required, workers must open the box door and reach their hands or tools inside. Due to the limited space inside the box, and the fact that electrical components are often located deep within, maintenance is not only limited in terms of operating space but also prone to inefficiency due to obstructed vision.

[0004] Although some distribution boxes attempt to set up push-out component mounting structures, they lack effective cushioning measures during the push-out process. The mounting plate is prone to generating a large impact when it pops out, which may cause electrical components to loosen or be damaged. At the same time, most of these structures can only be pushed out once, and cannot further adjust the distance of the component extending out of the box according to maintenance needs. When it is necessary to maintain the back of the electrical component or the wiring part, it is still necessary to disassemble the component or operate in a narrow space, which increases the difficulty of maintenance and prolongs the maintenance time. Utility Model Content

[0005] The purpose of this utility model is to provide a low-voltage integrated distribution box that is easy to maintain. In this utility model, the electrical components inside the distribution box can automatically pop out when the door is opened, effectively expanding the operating space and improving the convenience of maintenance; a buffer mechanism is provided during the movement to prevent impact damage; it also supports manual adjustment of the extension distance to adapt to different maintenance needs; key transmission parts are equipped with protective structures to prevent accidental contact and ensure convenient operation; the overall movement is stable, ensuring accurate positioning of electrical components, reducing maintenance interference, and solving existing technical problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A low-voltage integrated distribution box that is easy to maintain includes: The box body has a hinged door on one of its open sides; A movable plate and a mounting plate, wherein the mounting plate is fixedly installed on one side of the movable plate and is used to install electrical components; The pop-out assembly includes a base plate and multiple guide rods. The base plate is disposed inside the housing. The guide rods are fixedly installed on the side of the base plate facing the movable plate. The movable plate is slidably sleeved on the guide rods. A spring I is sleeved on the guide rods. The two ends of the spring I are respectively connected to the base plate and the movable plate. An arc-shaped abutment plate is fixedly installed on the inner side of the movable door. When the movable door is closed, the arc-shaped abutment plate abuts against the moving plate and compresses the spring I. When the movable door is opened, the spring I pushes the moving plate and moves the mounting plate toward the opening of the box.

[0007] Optionally, an abutment block is fixedly installed at the end of the guide rod away from the base plate. A movable ring is also slidably sleeved on the guide rod and a spring II is sleeved thereon. The spring II is located between the movable ring and the abutment block. The same rubber plate is slidably sleeved on two horizontally adjacent guide rods. The rubber plate abuts against the corresponding movable ring and provides cushioning when the movable plate pops out.

[0008] Optionally, one end of the spring II is connected to the abutment block, and the other end is connected to the moving ring.

[0009] Optionally, it also includes a moving component, which includes a screw that is rotatably mounted on the inner wall of the housing, with one end extending out of the housing and fixedly mounted with a gear; the base plate is provided with a limiting protrusion, and the screw is threadedly connected to the limiting protrusion, so that rotating the gear can drive the base plate to move.

[0010] Optionally, a protective shell is fixedly installed on the outside of the housing, the actuating gear is located inside the protective shell, and the protective shell has an opening on its side.

[0011] Optionally, a support rod is fixedly installed inside the box, and the limiting protrusion is slidably disposed on the support rod.

[0012] Optionally, there are two arc-shaped abutment plates, which are respectively located near the top and bottom of the movable door.

[0013] Optionally, the number of guide rods is four, located at the four corners of the substrate.

[0014] The embodiments of this utility model have the following beneficial effects: In this utility model, after the maintenance personnel open the movable door of the enclosure, they can push the mounting plate on which the electrical components are installed towards the opening of the enclosure without any additional manual operation, so that the electrical components are close to the opening of the enclosure. At this time, the maintenance personnel can access the electrical components without going deep into the enclosure, reducing the problem of limited operating space during maintenance and improving the convenience of maintenance operations. In this utility model, during the pop-out process of the mounting plate along with the moving plate, the spring II, in conjunction with the moving ring and the rubber plate, can form a buffer effect, reducing the impact force when the moving plate pops out, preventing the electrical components from becoming loose or damaged due to the impact, ensuring the stability of the electrical components during the movement process, and reducing the probability of electrical component failure after maintenance. In this utility model, when it is necessary to push the electrical components further out, the screw can be driven to rotate by turning the gear through the opening on the side of the protective shell, thereby pushing the base plate and the entire pop-out assembly to move outward, so that the mounting plate and electrical components can extend further out of the housing, meet the requirements of the extension distance of electrical components in different maintenance scenarios, improve the flexibility of maintenance, and reduce the operational difficulties caused by the inability to fully expose the maintenance parts. In this utility model, the protective shell can shield the gear, preventing external dust and debris from entering or personnel from accidentally touching the gear, thus ensuring the normal use of the adjustment structure; at the same time, the opening design on the side of the protective shell does not affect the normal operation of the gear by the staff, taking into account both protection and ease of operation. In this invention, the substrate slides on the support rod via limiting protrusions on both sides, which ensures the stability of the substrate during movement, avoids substrate displacement causing positional deviation of electrical components, further ensures the stability of electrical components during movement and maintenance, and reduces interference to maintenance operations caused by displacement deviation.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0022] In one embodiment: Please refer to Figures 1-5 As shown, this embodiment provides a power distribution box, including a box body 1, a movable plate 4, a mounting plate 5, a pop-out component, and a movable component.

[0023] In this embodiment, a movable door 2 is hinged to one side of the opening of the enclosure 1. The movable door 2 is used to close the opening of the enclosure 1. When the movable door 2 is in the closed state, it can protect the electrical components inside the enclosure 1 from external environmental interference; when the movable door 2 is opened, maintenance operations can be performed on the electrical components inside the enclosure 1.

[0024] In this embodiment, both the movable plate 4 and the mounting plate 5 are disposed inside the housing 1. The mounting plate 5 is fixedly installed on one side of the movable plate 4, and the electrical components are mounted and fixed on the mounting plate 5. By centrally installing the electrical components on the mounting plate 5, it is convenient to perform overall maintenance and replacement of the electrical components in the future.

[0025] In this embodiment, the pop-out assembly includes a base plate 6, which is located inside the housing 1 and provides support for the movable plate 4 and the mounting plate 5. The pop-out assembly also includes four guide rods 8, all of which are fixedly installed on one side of the base plate 6 near the four corners. The movable plate 4 is slidably fitted onto the outer walls of the four guide rods 8. Each of the four guide rods 8 has a spring I9 fitted onto its outer wall. One end of the spring I9 is ​​fixedly connected to one side of the base plate 6 via a spring seat, and the other end is fixedly connected to one side of the movable plate 4 via a spring seat. Two arc-shaped abutment plates 3 are fixedly installed on one side of the movable door 2, located near the top and bottom of the movable door 2 respectively. One side of each arc-shaped abutment plate 3 has an arc surface. When the movable door 2 is closed, the arc surface of the arc-shaped abutment plate 3 abuts against the movable plate 4, compressing the spring I9 and causing the movable plate 4 to be housed inside the housing 1. When the movable door 2 is opened, the spring force of the spring I9 pushes the movable plate 4, automatically ejecting it.

[0026] In this embodiment, to provide cushioning when the movable plate 4 pops out, an abutment block 10 is fixedly installed at one end of each guide rod 8. A movable ring 11 is slidably sleeved on the outer wall of the guide rod 8, and a spring II 12 is also sleeved on the outer wall of the guide rod 8. The spring II 12 is located between the movable ring 11 and the adjacent abutment block 10. One end of the spring II 12 is fixedly connected to one side of the abutment block 10 through a spring seat, and the other end is fixedly connected to one side of the movable ring 11 through a spring seat. The same rubber plate 13 is slidably sleeved on the outer walls of two horizontally adjacent guide rods 8, and the rubber plate 13 abuts against the two adjacent movable rings 11. When the movable plate 4 pops out, the rubber plate 13, under the action of the spring II 12, cushions the movable plate 4, preventing the movable plate 4 from causing a violent impact and damaging other internal components of the housing 1.

[0027] In this embodiment, multiple limiting protrusions 7 are fixedly installed on both sides of the substrate 6, and multiple limiting protrusions 7 near the top and bottom of the substrate 6 are slidably disposed on the outer wall of multiple support rods fixedly installed inside the housing 1. Through the cooperation of the limiting protrusions 7 and the support rods, the substrate 6 can be supported and its direction of movement can be restricted, so that the substrate 6 can only move in a specific direction, ensuring the stability of the movement of the moving plate 4 and the mounting plate 5.

[0028] In this embodiment, the moving component is used to actively drive and adjust the substrate 6, thereby further pushing out the moving plate 4 and the mounting plate 5. The moving component includes a screw 14 rotatably mounted on the inner wall of one side of the housing 1. One end of the screw 14 rotatably passes through one side of the housing 1, and the screw 14 is threadedly connected to the outer wall of one of the limiting protrusions 7. A toggle gear 15 is fixedly mounted on one end of the screw 14. By actuating the toggle gear 15, the screw 14 can be driven to rotate. Since the screw 14 is threadedly connected to the limiting protrusion 7, when the screw 14 rotates, it will drive the substrate 6 to move, thereby further pushing out the moving plate 4 and the mounting plate 5, facilitating more detailed operation of electrical components by maintenance personnel.

[0029] This application can be used in the field of power distribution equipment technology, or in other fields applicable to this application.

[0030] In another embodiment: Reference Figure 1 , 2 5. A low-voltage integrated distribution box that is easy to maintain and is applied to the field of power distribution equipment technology. In this embodiment, to protect the actuating gear 15, a protective housing 16 is fixedly installed on one side of the housing 1. The actuating gear 15 is located inside the protective housing 16. The protective housing 16 acts as a shield for the actuating gear 15, preventing external objects from accidentally touching the actuating gear 15 and affecting its normal operation. An opening is provided on one side of the protective housing 16, allowing maintenance personnel to easily operate the actuating gear 15 through the opening.

[0031] In this embodiment, a positioning lock is built into the movable door 2 near one side. The positioning lock is used to lock the movable door 2 to the housing 1.

[0032] The usage process and working principle of this utility model technical solution are as follows: In use, when the movable door 2 is in the closed and locked state, the arc-shaped abutment plate 3 on the inner side of the movable door 2 presses against the moving plate 4, causing the moving plate 4 to slide along the guide rod 8 towards the base plate 6. At this time, the spring I9 is ​​in a compressed state. The electrical components are fixed on the mounting plate 5, which ensures that the electrical components can be stably installed inside the housing 1.

[0033] When the movable door 2 is opened, the arc-shaped abutment plate 3 releases pressure on the movable plate 4. Spring I 9 releases its elastic force, thereby pushing the movable plate 4 along the guide rod 8 towards the opening of the housing 1. At the same time, it can drive the mounting plate 5 and electrical components to a position close to the opening of the housing 1, realizing the automatic ejection of the electrical components, thus facilitating maintenance and repair of the electrical components. During the movement, the movable plate 4 pushes the rubber plate 13 to abut against the moving ring 11. Spring II 12 applies pressure to spring II 12 through the moving ring 11. Spring II 12 undergoes elastic deformation to buffer the movement of the movable plate 4, thereby preventing damage to the electrical components from the impact when the movable plate 4 automatically pops out.

[0034] If the movable plate 4 needs to be moved further, the operator can turn the shift gear 15 through the opening on the side of the protective housing 16, thereby driving the screw 14 to rotate. Since the screw 14 is threadedly engaged with the limiting protrusion 7, the rotational motion is converted into linear movement of the base plate 6, thereby pushing the entire ejection assembly outward, allowing the movable plate 4 and the mounting plate 5 to extend further outward.

[0035] When the movable door 2 is closed, the arc-shaped abutment plate 3 can abut against the movable plate 4 and apply pressure, which can cause the movable plate 4 to slide in the opposite direction along the guide rod 8, recompressing the spring I 9 until the movable plate 4 is completely retracted into the box 1.

[0036] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0037] It should be noted that in the description of this specification, descriptions such as "first" and "second" are only used to distinguish the features and do not have any actual order or directional meaning. This application is not limited to this.
