Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and more specifically, to a power distribution cabinet with cable management function. 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 suitable for situations where the load is relatively dispersed and there are few circuits. Furthermore, distribution cabinets are an important part of the power grid, and the power grid circuits can be controlled by installing electrical equipment for power distribution.

[0003] In the existing technology, power distribution cabinets with cable management functions require manual cable management one by one during the cable management process. For example, the patent with publication number CN118399208A, application date June 21, 2024, is entitled "A Cable Centralized Routing and Organizing Mechanism for Power Distribution Cabinets and Its Usage Method".

[0004] According to the aforementioned public documents, when organizing the cables, it is necessary to manually thread the cables one by one through the fixing plate, which is very inconvenient. Furthermore, when organizing the cables, it is necessary to rotate the fixing plate one by one to tighten the cables, which is also very inconvenient during the cable winding process. Summary of the Invention

[0005] This invention provides a power distribution cabinet with cable management function, which aims to solve the problem that existing power distribution cabinets with cable management function are inconvenient to use during the cable management process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This invention provides a power distribution cabinet with cable winding and management function, including a power box body, a support frame is provided at the bottom of the interior of the power box body, a cable winding shaft is rotatably mounted on the support frame, and a through groove corresponding to the cable winding shaft is provided at the bottom of the power box body.

[0008] The take-up shaft is provided with several take-up components along its length;

[0009] The take-up assembly includes a winding sleeve rotatably mounted on the take-up shaft. The outer wall of the winding sleeve is provided with a winding groove along its own circumference, and a clamping plate for clamping the wire is provided in the winding groove.

[0010] The inner wall of the winding sleeve is provided with a spring plunger, and the circumferential direction of the take-up shaft is provided with a number of plunger holes that cooperate with the spring plunger.

[0011] In one embodiment, a turntable is fixedly provided on the outer wall of the take-up shaft, the diameter of the turntable is D1, the diameter of the take-up shaft is D2, and D1>2D2.

[0012] In one embodiment, a locking sleeve is threaded onto the outer side of the take-up shaft, and a locking disc is provided circumferentially on the locking sleeve; when the locking disc is rotated, the locking sleeve moves axially along the take-up shaft, and the end of the locking sleeve abuts against the support frame, thereby restricting the rotation of the take-up shaft.

[0013] In one embodiment, the wire clamping plate is provided with an arc-shaped plate, one side of which is rotatably connected to the winding groove, and the other side of which is provided with a locking through hole. The winding groove is provided with a locking hole that mates with the locking through hole, and the bolt passes through the locking through hole and is threadedly connected to the locking hole.

[0014] In one embodiment, the arc-shaped plate is provided with a plurality of pressing edges arranged along the circumferential direction, and the plurality of pressing edges are arranged along the axial direction of the arc-shaped plate.

[0015] In one embodiment, the pressure rib is made of an elastic material.

[0016] In one embodiment, the two sides of the winding groove are inclined, so that the opening of the winding groove gradually increases in the direction away from the take-up shaft.

[0017] In one embodiment, the support frame is provided in two sets, and the two sets of support frames are respectively arranged on both sides of the electrical box in the width direction.

[0018] In one embodiment, a motor is provided at one end of the take-up shaft.

[0019] In one embodiment, the motor is a worm gear reducer motor.

[0020] The beneficial effects of this invention compared to the prior art are as follows: This application provides a take-up shaft at the bottom inside the electrical box body, with several take-up components on the shaft. These components allow for the take-up of electrical wires. In use, the clamping plate is opened, and the wire is then clamped around the winding groove. After multiple wires are clamped onto several winding sleeves in sequence, the take-up shaft is rotated. Initially, the wire is relatively long, and when the take-up shaft is rotated, the wire exerts almost no or minimal tension on the winding sleeves. At this point, the take-up shaft, through the cooperation of the spring plunger and plunger hole, drives the winding sleeves to rotate synchronously, allowing the wire to be tightly wound around the outside of the winding sleeves, thus effectively storing the wire. As the winding sleeve rotates more, the number of turns of the wire around it also gradually increases. When the wire is fully taut, the wire exerts tension on the winding sleeve, causing the spring plunger to disengage from the plunger hole when the take-up shaft rotates. This allows the winding sleeve and the take-up shaft to rotate relative to each other. At this point, no matter how the take-up shaft is rotated, the winding sleeve will not rotate. Because each winding sleeve is independent, when the wires are of different lengths, the winding sleeve holding the shorter wire rotates relative to the take-up shaft first, while the winding sleeve holding the longer wire continues to rotate synchronously with the take-up shaft. This allows for the simultaneous take-up and management of multiple wires of different lengths, making it very convenient and easy to use. When the internal structure of the electrical box needs to be inspected later, each winding sleeve can be rotated individually to allow the wire on the sleeve to be lengthened for easy rewiring.

[0021] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention, it can be implemented according to the contents of the specification. In order to make the above and other objects, features and advantages of the present invention more obvious and understandable, preferred embodiments are described in detail below.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0042] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0043] Please see Figure 1-9 This invention provides a power distribution cabinet with cable winding and management function, including: a power box body 1, a support frame 2 is provided at the bottom inside the power box body 1, a cable winding shaft 3 is rotatably provided on the support frame 2, and a through groove 11 corresponding to the cable winding shaft 3 is provided at the bottom of the power box body 1;

[0044] The take-up shaft 3 is provided with a plurality of take-up components 4 along its length direction;

[0045] The take-up assembly 4 includes a winding sleeve 41 rotatably mounted on the take-up shaft 3. The outer side wall of the winding sleeve 41 is provided with a winding groove 411 along its own circumferential direction. A clamping plate 42 for clamping the wire is provided in the winding groove 411.

[0046] The inner wall of the winding sleeve 41 is provided with a spring plunger 43, and the take-up shaft 3 is provided with a plurality of plunger holes 31 that cooperate with the spring plunger 43 evenly distributed in the circumferential direction.

[0047] In this embodiment, a take-up shaft 3 is provided at the bottom inside the electrical box body 1. Several take-up components 4 are provided on the take-up shaft 3, which can take up the wires. In use, the clamping plate 42 is opened, and then the wires are clamped around the winding groove 411 by the clamping plate 42. After multiple wires are clamped onto several winding sleeves 41 in sequence, the take-up shaft 3 is rotated. Initially, the length of the wire is relatively long. At this time, when the take-up shaft 3 is rotated, the wires exert almost no or little tension on the winding sleeves 41. At this time, the take-up shaft 3 can drive the winding sleeves 41 to rotate synchronously through the cooperation of the spring plunger 43 and the plunger hole 31, so that the wires can be tightly wound around the outside of the winding sleeves 41, which plays a role in storing the wires. As the winding sleeve 41 rotates more, the number of turns of the wire around it also gradually increases. When the wire is fully taut, it exerts tension on the winding sleeve 41. This causes the spring plunger 43 to disengage from the plunger hole 31 when the take-up shaft 3 rotates, resulting in relative rotation between the winding sleeve 41 and the take-up shaft 3. At this point, the winding sleeve 41 will not rotate regardless of how the take-up shaft 3 is rotated. Since each winding sleeve 41 is independent, when the wires are of different lengths, the winding sleeve 41 holding the shorter wire rotates relative to the take-up shaft 3 first, while the winding sleeve 41 holding the longer wire continues to rotate synchronously with the take-up shaft 3. This allows for the simultaneous take-up and arrangement of multiple wires of different lengths, making it very convenient and easy to use.

[0048] In addition, when the internal structure of the electrical box 1 needs to be inspected later, each winding sleeve 41 can be rotated individually to extend the wires on the winding sleeve 41 for easy rewiring.

[0049] In this embodiment, a mounting hole 412 is provided at the center of the winding sleeve 41, and the take-up shaft 3 is rotatably disposed within the mounting hole 412. An inner wall hole 413 is provided on the inner sidewall of the mounting hole 412, and the axis of the inner wall hole 413 is perpendicular to the axis of the mounting hole 412. A spring plunger 43 is disposed within the inner wall hole 413. In this embodiment, multiple plunger holes 31 are provided, and the multiple plunger holes 31 are evenly distributed in the circumferential direction of the take-up shaft 3. In this embodiment, the included angle between the centers of two adjacent plunger holes 31 is 5°. The number of spring plungers 43 determines the ease with which the winding sleeve 41 and the take-up shaft 3 can rotate relative to each other. The number of spring plungers 43 is configured according to the actual situation. In this embodiment, four spring plungers 43 are provided, and the four spring plungers 43 are evenly distributed on the inner sidewall of the mounting hole 412.

[0050] The spring plunger 43 structure in this embodiment includes a plunger spring and a plunger ball disposed in the inner wall hole 413. The plunger spring pushes the plunger ball so that the plunger ball abuts against the plunger hole 31. The plunger hole 31 is arc-shaped, and the arc profile of the cross-section of the plunger hole 31 is a minor arc.

[0051] In a further embodiment, such as Figure 6 As shown, in this embodiment, two sets of support frames 2 are provided, respectively located at both ends of the through slot 11 along its length. The support frames 2 provide support at both ends of the take-up shaft 3 along its length, allowing the take-up shaft 3 to be mounted above the through slot 11. The through slot 11 facilitates the entry of the wire into the interior of the electrical box body 1 from the bottom.

[0052] In one embodiment, such as Figure 6 As shown, a turntable 5 is fixedly installed on the outer wall of the take-up shaft 3. The diameter of the turntable 5 is D1, and the diameter of the take-up shaft 3 is D2, where D1>2D2.

[0053] In this embodiment, a turntable 5 is fixedly installed on the outer wall of the take-up shaft 3. The diameter of the turntable 5 is larger than the diameter of the take-up shaft 3. By rotating the turntable 5, the take-up shaft 3 is driven to rotate, enabling manual rotation of the take-up shaft 3 and making its rotation easier. In this embodiment, the diameter of the turntable 5 is more than twice that of the take-up shaft 3, which facilitates the rotation of the take-up shaft 3.

[0054] In addition, several anti-slip ridges 51 are provided on the end faces of both sides of the turntable 5, arranged radially. The anti-slip ridges 51 can increase the friction of the end faces of both sides of the turntable 5, thereby facilitating the rotation of the turntable 5.

[0055] In a further embodiment, such as Figure 4 or Figure 6 As shown, a locking sleeve 6 is threaded onto the outer side of the take-up shaft 3, and a locking disc 61 is fixedly provided on the circumference of the locking sleeve 6; rotating the locking disc 61 causes the locking sleeve 6 to move along the axial direction of the take-up shaft 3, and the end of the locking sleeve 6 abuts against the support frame 2 to restrict the rotation of the take-up shaft 3.

[0056] In this embodiment, by rotating the locking disc 61, the locking sleeve 6 can be driven to rotate synchronously, so that the locking sleeve 6 can abut against the support frame 2, thereby locking the take-up shaft 3, so that the take-up shaft 3 can be kept in a fixed state after tightening multiple wires.

[0057] In a further embodiment, such as Figure 7 and Figure 8 As shown, the wire clamping plate 42 is provided with an arc plate 421. One side of the arc plate 421 is rotatably connected to the winding groove 411. The other side of the arc plate 421 is provided with a locking through hole. The winding groove 411 is provided with a locking hole that cooperates with the locking through hole. The bolt 422 passes through the locking through hole and is threadedly connected to the locking hole.

[0058] In this embodiment, an arc-shaped plate 421 is provided on the clamping plate 42, which can mate with the outer surface of the wire. One side of the arc-shaped plate 421 is hinged to the winding groove 411, allowing the arc-shaped plate 421 to rotate relative to the winding groove 411. A locking hole is provided on the other side of the arc-shaped plate 421. A bolt 422 passes through the locking hole and is threaded into the locking hole, thereby fixing the clamping plate 42 and clamping the wire, thus fixing the wire within the winding groove 411.

[0059] In a further embodiment, such as Figure 7 and Figure 8 As shown, the arc-shaped plate 421 is provided with a plurality of pressing ridges 423 arranged along the circumferential direction, and the plurality of pressing ridges 423 are arranged along the axial direction of the arc-shaped plate 421.

[0060] In this embodiment, a pressing ridge 423 is provided on the arc plate 421. The pressing ridge 423 can press firmly on the surface of the wire, thereby increasing the clamping force on the wire.

[0061] In a further embodiment, the pressure rib 423 is made of an elastic material.

[0062] In this embodiment, the pressure rib 423 is made of an elastic material, which prevents the pressure rib 423 from damaging the surface of the wire and causing breakage. Furthermore, when the pressure rib 423 is pressed against the surface of the wire, a greater force can be used to pull the wire, allowing it to slide within the arc-shaped plate 421, facilitating adjustment of the wire's pressed position. In this embodiment, the pressure rib 423 is made of sponge or rubber material.

[0063] In a further embodiment, such as Figure 6 As shown, the two sides of the winding groove 411 are inclined, so that the opening of the winding groove 411 gradually increases in the direction away from the take-up shaft 3.

[0064] In this embodiment, the openings on both sides of the winding groove 411 gradually widen, so that the wire can be tightened inside the winding groove 411 when the wire is wound up.

[0065] In another embodiment, such as Figure 9 As shown, a motor 7 is provided at one end of the take-up shaft 3.

[0066] In this embodiment, a motor 7 is provided at the end of the take-up shaft 3, which can directly drive the take-up shaft 3 to rotate, thus eliminating the trouble of manually rotating the take-up shaft 3. In this embodiment, the motor 7 is an integrated geared motor with a built-in reducer.

[0067] In a further embodiment, the motor 7 is a worm gear reducer motor.

[0068] In this embodiment, the motor 7 is configured as a worm gear reducer motor. When the worm gear reducer motor stops working, it has a positioning function to prevent the take-up shaft 3 from rotating.

[0069] This application achieves the functions of simultaneous wire take-up and independent wire management for multiple wires of different lengths through the above structure, specifically including the following processes:

[0070] (1) Synchronous winding: Open the clamp plate 42 and fix multiple wires onto multiple independent winding sleeves 41 respectively.

[0071] Rotate the take-up shaft 3. Since the wire is not taut, the spring plunger 43 is engaged in the plunger hole 31, causing all the winding sleeves 41 to rotate synchronously, and the wire is wound in the winding groove 411 for storage.

[0072] (2) Automatic release: When a shorter wire is fully tightened, the corresponding winding sleeve 41 of the wire is subjected to a reverse pull.

[0073] When the pulling force exceeds the elastic force of the spring plunger 43, the plunger disengages from the plunger hole 31, causing the winding sleeve 41 to slide relative to the shaft, thus stopping the winding process.

[0074] Meanwhile, the winding sleeve 41 corresponding to the longer wires continues to rotate with the shaft to wind up the wires until all wires are taut and the rotation stops. This achieves synchronous and automatic winding of wires of different lengths.

[0075] (3) Inspection and laying: During later inspections, any one of the winding sleeves 41 can be manually rotated independently to lay out the corresponding wires separately without interfering with other lines.

[0076] (4) Locking and driving: The shaft can be locked by the locking sleeve 6 against the support frame 2 to prevent the wire from loosening.

[0077] An optional motor 7 (especially a worm gear motor) can be used to achieve electric winding, and the self-locking function of the motor 7 can be used to maintain positioning.

[0078] Compared with the prior art, this application has the following advantages:

[0079] (1) Strong compatibility: It solves the problem that traditional cable management mechanisms cannot handle multiple cables of different lengths. Through the independent spring plunger 43 clutch structure, cables of different lengths can be automatically stopped during the winding process.

[0080] (2) Convenient maintenance: Each winding sleeve 41 can rotate independently, which makes it convenient to lay out the wire separately when repairing or replacing a specific line in the later stage, without disassembling the entire line, which greatly improves maintenance efficiency.

[0081] (3) Damage protection design: The clamping edge 423 of the wire clamping plate 42 is made of elastic materials such as sponge or rubber, which can provide sufficient clamping force and prevent the wire sheath from being crushed or worn.

[0082] (4) The opening of the winding groove 411 is expanded outward to guide the wires to be smoothly gathered and avoid the wires getting stuck.

[0083] (5) Effortless and stable operation: Equipped with a large diameter turntable 5, which conforms to the lever principle, making manual line winding easier.

[0084] The locking sleeve 6 design can fix the winding after the cable is wound up, preventing the cable from coming loose due to vibration or gravity.

[0085] (6) Diverse drive: It can be operated manually or automated by adding a motor 7. In particular, the application of the worm gear motor utilizes its self-locking characteristics to maintain the position lock even after power failure, which increases the reliability and safety of use.

[0086] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
