Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and in particular to a distribution box that is easy to maintain. Background Art

[0002] Distribution boxes, electrical equipment with their compact size, easy installation, and unique technical features, play a vital role in fixed locations. They serve as the central circuit distribution box for user electricity, effectively distributing power and facilitating circuit opening and closing. Their configuration and functionality are unrestricted by site, offering a wide range of applications, stable and reliable operation, high space utilization, minimal footprint, and environmental benefits.

[0003] In related technology, a distribution box consists of a box body and a door mounted on the box body. Several support plates are fixed horizontally inside the box body, and the relevant electrical components are fixed to the upper surfaces of the support plates with screws. To visually display the operating status of the electrical components, an indicator assembly is also added to the box body, including an indicator plate fixed inside the box body and several indicator lights. These indicators are connected to the electrical components via complex cables. When the status of the electrical components changes, the indicators change color, providing instant status feedback.

[0004] When using cables to connect indicator lights and corresponding electrical components, the installation process becomes cumbersome and time-consuming due to the numerous cables connected to the indicator panel. Especially when the space inside the box is relatively narrow, the installation efficiency is seriously affected. This not only increases the difficulty of construction, but may also cause safety hazards due to improper operation. There is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a distribution box that is easy to maintain, so as to solve the problem of low installation efficiency when using cables to connect indicator lights and electrical components in the above-mentioned related technologies.

[0006] The present application provides a distribution box that is easy to maintain and adopts the following technical solutions: A distribution box that is easy to maintain, includes a box body and a box door installed on the box body, a partition plate is fixedly provided in the middle of the box body in the vertical direction, and a plurality of heat dissipation openings are opened on the vertical side surfaces of the box body; a support plate is installed on the vertical inner wall of the box body, and a limit plate opposite to the support plate is fixedly provided on the side of the partition plate facing the support plate, an indicator plate is provided in the box body, and a plurality of indicator lights are fixed on the indicator plate; a rotating shaft that is rotatably connected to one side of the indicator plate is fixedly provided on the support plate in the vertical direction, and the other side of the support plate can be rotated around the rotating shaft to abut against the limit plate, and a locking member is provided in the box body for detachably mounting the end of the indicator plate away from the support plate on the limit plate.

[0007] By adopting this technical solution, when maintenance or cable connections are required, operators simply unlock the locking mechanism and easily rotate the indicator panel around its axis to a more spacious and accessible position, greatly simplifying the workflow and reducing operational difficulty. After completing maintenance or cable connections, operators can easily return the indicator panel to its original position, ensuring stable and reliable operation. This design not only improves work efficiency but also enhances operational safety, making distribution box maintenance and management easier and more efficient.

[0008] Optionally, the locking member includes a locking rod, a locking handle fixed to one end of the locking rod, and a locking folding plate fixed to the other end of the locking rod; the end of the indicator plate away from the support plate is provided with a locking through hole for the locking rod to pass through and rotate; the locking handle is located on the side of the indicator plate close to the box door, and the locking folding plate is located on the side of the indicator plate away from the box door; when the indicator plate and the limit plate are in abutment state, the locking folding plate can rotate with the locking rod to the side of the limit plate away from the box door.

[0009] By adopting the above technical solution, the locking rod passes through the locking hole of the indicator plate and is fixed by the locking handle and locking flap. This allows the operator to conveniently control the locking rod by turning the locking handle, thereby easily locking or unlocking the indicator plate in the desired position. The locking handle is located on the side of the indicator plate near the door, making it easy for the operator to operate from the outside, while the locking flap can rotate with the locking rod to the side of the limit plate away from the door to achieve a stable fixation. This design not only simplifies the operation steps and improves work efficiency, but also ensures the stability and reliability of the indicator plate in the fixed state, effectively avoiding safety hazards caused by improper operation or external interference.

[0010] Optionally, a protective plate for blocking several heat dissipation vents is fixedly provided on the inner wall of the box, and an air inlet hole overlapping with the heat dissipation vents is opened on the protective plate; a protective cover with an upward opening is fixedly provided on the opening edge of the air inlet hole away from the heat dissipation vents, and a drainage cover with a downward opening is fixedly provided on the opening edge of the heat dissipation vent away from the protective plate.

[0011] By adopting the above technical solution, the protective plate and its air inlet design not only ensure air circulation and achieve heat dissipation, but also effectively prevent external debris or small animals from entering the distribution box, thereby improving the safety and stability of the distribution box. Furthermore, the provision of a protective cover and a drainage hood further enhances the protective effect. The upward opening of the protective cover prevents rainwater or other liquids from splashing into the air inlet from above, while the downward opening of the drainage hood guides air entering the heat dissipation vents into the distribution box, while preventing debris or small animals from entering through the heat dissipation vents.

[0012] Optionally, a wiring port is provided on the partition plate, and two clamping plates are slidably provided on the partition plate in a vertical direction toward the support plate, and the two clamping plates are respectively located above and below the wiring port. An arc-shaped notch is provided on the side surfaces of the two clamping plates close to each other, and an elastic pad is fixed on the inner wall of the arc-shaped notch. An elastic extrusion part is fixed on the partition plate to enable the two clamping plates to slide toward each other.

[0013] By adopting this technical solution, the wiring port on the partition plate facilitates cable access, while the upper and lower clamping plates securely hold the cables, preventing them from loosening or falling out. The curved notches in the clamping plates, combined with the elastic pads, accommodate cables of varying diameters while providing effective cushioning and protection against damage. Furthermore, the elastic extrusion element enables the two clamping plates to automatically slide toward each other and tightly clamp the cables, eliminating manual operation and significantly improving wiring efficiency and stability.

[0014] Optionally, a positioning rod is fixed on the sides of the two clamping plates that are away from each other, and the elastic extrusion member includes a first spring and a limit block fixed on the partition plate, and the limit block is provided with a limit hole for the positioning rod to pass through, and the two ends of the first spring are respectively fixedly connected to the sides of the limit block and the clamping plates that are close to each other.

[0015] By adopting this technical solution, the first spring, as the core component of the elastic extrusion element, not only provides continuous extrusion force to the clamping plate, ensuring stable cable clamping, but also, through its elastic properties, absorbs and mitigates external impact forces on the cable to a certain extent, protecting the cable from damage. Furthermore, the first spring's ends are fixedly connected to the limit block and the clamping plate, respectively, ensuring stable transmission of the spring force and improving the reliability and durability of the clamping mechanism.

[0016] Optionally, a locking plate is slidably provided on the partition plate and is located on the side of the clamping plate close to the box door. A locking notch is provided on the side of the locking plate facing the clamping plate. An extension rod is fixed on the side of the locking plate away from the clamping plate, and an abutment plate is vertically fixed on the end of the extension rod; a control plate is hinged on the upper edge of the indicator plate and an adjusting member for adjusting the rotation of the control plate is provided; the control plate can be rotated to a horizontal state and fixed, and the control plate in this state can squeeze the abutment plate when the indicator plate is fixed on the limit plate, so that the edges of the two clamping plates close to the box door are jointly stuck in the locking notch.

[0017] By adopting this technical solution, the coordinated design of the locking plate and the locking notch enables the two clamping plates to automatically snap into the locking notch through the squeezing action of the control panel when the indicator panel is fixed, thus firmly locking the cable. This automatic locking mechanism not only simplifies operation and improves work efficiency, but also effectively prevents the cable from loosening or falling due to human negligence or external interference. Furthermore, the coordination between the control panel and the adjustment member allows the operator to flexibly adjust the position and status of the control panel according to actual needs, further enhancing operational flexibility and convenience.

[0018] Optionally, an oblique support rod is hinged on the extension rod, and a conical block is fixed to the end of the oblique support rod away from the extension rod. An abutment groove for the conical block to be rotatably engaged is provided on the side of the abutment plate close to the locking plate.

[0019] By adopting the above technical solution, when the conical block is interference-fitted into the abutment groove, the connection stability between the extension rod and the abutment plate is enhanced.

[0020] Optionally, the conical block can be inserted between the two clamping plates when the diagonal support rod rotates away from the abutment plate.

[0021] By adopting the above technical solution, when the cables are laid out and the cables need to be passed through the wiring port, the locking plate is slid away from the clamping plate in advance to release the lock on the clamping plate, and then the diagonal support rod is rotated away from the abutment plate so that the conical block can be inserted between the two clamping plates. In this state, the two clamping plates slide back to back under the action of the conical block, making it easier for the cables to pass through the wiring port.

[0022] Optionally, the support plate is rotatably connected to the inner wall of the box, an elastic clip is provided on the support plate, and a number of positioning grooves for the elastic clip to be snapped into are evenly opened on the inner wall of the box; the indicator plate can be rotated downward to a vertical state and fixed after the support plate rotates, and the control panel can be rotated to a state parallel to the vertical inner wall of the box and fixed when the indicator plate is in a vertical downward state.

[0023] By adopting the above-mentioned technical solution, the pivoting connection between the support plate and the inner wall of the box, and the coordinated design of the elastic clips and positioning grooves, the support plate and indicator plate can be flexibly rotated and fixed in different positions according to actual needs, providing operators with a more spacious and convenient operating space. In particular, when the indicator plate rotates to a vertical downward position with the support plate, the control panel can also be rotated and fixed parallel to the vertical inner wall of the box. This not only facilitates cable connection and maintenance operations for operators, but also effectively utilizes the internal space of the distribution box, improving space utilization.

[0024] Optionally, a blocking plate located above the protective cover is provided in the box body, and vertical rods located on both sides of the protective plate and capable of sliding up and down are slidably provided on the inner wall of the box body in a vertical direction, and both sides of the blocking plate are fixedly connected to the side surfaces of the two vertical rods close to each other; an elastic reset part is provided in the box body to drive the vertical rod to slide upward, and a bending rod facing the partition plate is vertically fixed to the lower end of the vertical rod; when the indicator plate is in a vertical downward state, the control plate can be rotated to a state where the upper side surface of the bending rod is abutted after the bending rod moves downward with the vertical rod. In this state, the blocking plate moves downward to block the opening of the protective cover.

[0025] By adopting this technical solution, when it's raining or humid outside, the operator can pre-position the indicator panel to a vertically downward position and, overcoming the elastic force of the return element, press the blocking plate downward. The operator then rotates the control panel above the bending rod, aligning the lower side of the locking plate with the upper side of the bending rod. The blocking plate then moves downward, completely sealing the opening in the protective cover. This design effectively prevents rainwater and moisture from entering the distribution box through the protective cover, avoiding problems such as short circuits and equipment damage caused by humid environments, and ensuring the safe and stable operation of the distribution box and its internal equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When maintenance or cable connections are required, operators simply unlock the locking mechanism and easily rotate the indicator panel around its axis to a more spacious and accessible position, greatly streamlining the workflow and reducing operational difficulty. After completing maintenance or cable connections, operators can easily return the indicator panel to its original position, ensuring stable and reliable operation. This design not only improves work efficiency but also enhances operational safety, making distribution box maintenance and management easier and more efficient.

[0027] 2. In rainy or humid weather, the operator can pre-position the indicator panel to a vertically downward position and depress the blocking plate downward, overcoming the force of the elastic reset element. The operator then rotates the control panel above the bending rod, aligning the lower side of the locking plate with the upper side of the bending rod. The blocking plate then moves downward, completely sealing the opening of the protective cover. This design effectively prevents rainwater and moisture from entering the distribution box through the protective cover, avoiding problems such as short circuits and equipment damage caused by humid environments, and ensuring the safe and stable operation of the distribution box and its internal equipment.

[0033] Refer to 3 and Figure 4 A support plate 14 is fixed to the vertical inner wall of the box body 1 by screws, wherein a limit plate 111 opposite to the support plate 14 is fixed to the side of the partition plate 11 facing the support plate 14 by screws, and an indicator assembly 4 is provided in the box body 1, wherein the indicator assembly 4 includes an indicator plate 41 installed in the box body 1 along the horizontal direction, and a plurality of indicator lights 411 are fixed on the indicator plate 41; A rotating shaft 141 is fixedly provided on the support plate 14 in the vertical direction and is rotatably connected to one side of the indicator plate 41. The other side of the support plate 14 can be rotated around the axis of the rotating shaft 141 until it abuts against the limit plate 111. A locking member 42 is provided in the box body 1 to detachably install the side of the indicator plate 41 away from the support plate 14 on the limit plate 111.

The end of the indicator plate 41 away from the support plate 14 is provided with a locking through hole 412 for the locking rod 421 to pass through and rotate. The locking handle 422 is located on the side of the indicator plate 41 close to the box door 2, and the locking folded plate 423 is located on the side of the indicator plate 41 away from the box door 2. When it is necessary to fix the indicator plate 41, rotate the indicator plate 41 around the rotating shaft 141 in the direction away from the box door 2, so that the end of the indicator plate 41 away from the support plate 14 abuts against the limit plate 111, and then rotate the locking handle 422 to rotate the locking folding plate 423 along the locking rod 421 to the side of the limit plate 111 away from the box door 2; when it is necessary to connect the cable to the indicator plate 41, first rotate the locking handle 422 in the opposite direction to release the lock of the indicator plate 41, and then rotate the indicator plate 41 in the direction close to the box door 2, and then the cable can be connected.

[0035] The implementation principle of the embodiment of this application is: The enclosure 1 effectively divides the interior space through partitions 11. The heat dissipation vents 12, combined with the protective plate 3, ensure the enclosure 1's heat dissipation performance while preventing the ingress of foreign matter through the design of the protective cover 32 and the drainage cover 13. Furthermore, the innovative indicator plate 41 within the enclosure 1, coordinated through the support plate 14, the stop plate 111, and the locking member 42, allows for flexible rotation and fixation. When maintenance or cable connections are required, the operator can easily unlock the indicator plate 41, rotate it to a convenient position, and then secure it back in place.

[0036] Example 2: Reference Figure 6 and Figure 7The difference between the embodiment of the present application and embodiment 1 is that a wiring port 112 is provided on the partition plate 11, and a clamping assembly 5 is provided in the box body 1, wherein the clamping assembly 5 includes two clamping plates 51 slidably arranged along the vertical direction on the side of the partition plate 11 facing the support plate 14, and the two clamping plates 51 are respectively located above and below the wiring port 112, and an arc-shaped notch 511 is provided on the side surfaces of the two clamping plates 51 close to each other, and an elastic pad 52 made of rubber material is fixed to the inner wall of the arc-shaped notch 511 by glue, and an elastic extrusion member 53 is fixed on the partition plate 11 to make the two clamping plates 51 slide toward each other.

[0037] Reference Figure 7 A positioning rod 512 is fixed on the sides of the two clamping plates 51 that are away from each other. The elastic extrusion member 53 includes a first spring 531 in a compressed state and a limiting block 532 fixed on the partition plate 11. The limiting block 532 is provided with a limiting hole for the positioning rod 512 to pass through. The two ends of the first spring 531 are respectively fixedly connected to the limiting block 532 and the sides of the clamping plate 51 that are close to each other.

[0038] Reference Figure 8 and Figure 9 A locking plate 54 is slidably provided on the partition plate 11 and is located on the side of the clamping plate 51 close to the door 2, wherein a locking notch 541 is provided on the side of the locking plate 54 facing the clamping plate 51, and an extension rod 55 is fixed on the side of the locking plate 54 away from the clamping plate 51, and an abutment plate 56 is fixed on the end of the extension rod 55; A control panel 43 is hingedly connected to the upper edge of the indicator panel 41. An adjusting member 44 is provided for adjusting the rotation of the control panel 43. The adjusting member 44 is a butterfly bolt 441. The state of the control panel 43 can be adjusted by tightening or loosening the hinge between the control panel 43 and the indicator panel 41. The control panel 43 can be rotated to a horizontal state and fixed. When the indicator plate 41 is fixed on the limit plate 111, the control plate 43 in a horizontal state can squeeze the abutment plate 56, so that the two clamping plates 51 close to the edge of the box door 2 are jointly clamped into the locking notch 541, thereby enhancing the clamping stability of the two clamping plates 51 on the wiring harness passing through the wiring port 112; there is a gap between the indicator plate 41 and the partition plate 11, which is in a parallel state with the side wall of the partition plate 11, that is, when the indicator plate 41 is rotated in or out, the control plate 43 will not collide or knock against the side wall of the partition plate 11, and the two will not interfere with each other.

[0039] Reference Figure 10The extension rod 55 is hinged with an oblique support rod 57, wherein the end of the oblique support rod 57 away from the extension rod 55 is fixed with a tapered block 571, which can be fastened by bolts to adjust and fix the rotation angle of the oblique support rod 57; an abutment groove 561 for the tapered block 571 to rotate and snap into is opened on the side of the abutment plate 56 close to the locking plate 54; when the tapered block 571 is interference fit into the abutment groove 561, the connection stability of the extension rod 55 and the abutment plate 56 is enhanced; When laying out the cables and needing to pass the cables through the wiring port 112, the locking plate 54 is slid away from the clamping plate 51 in advance to release the lock on the clamping plate 51, and then the diagonal support rod 57 is rotated away from the abutment plate 56 so that the conical block 571 can be inserted between the two clamping plates 51. In this state, the two clamping plates 51 slide back to back under the action of the conical block 571, which facilitates cable layout.

[0040] Reference Figure 11 and Figure 12 The support plate 14 is rotatably connected to the inner wall of the box body 1. An elastic clip 15 is provided on the support plate 14. The elastic clip 15 includes a compression spring 151 and an arc-shaped protrusion 152. A placement groove 142 for the compression spring 151 and the arc-shaped protrusion 152 is provided on the support plate 14. The compression spring 151 presses one side of the arc-shaped protrusion 152 so that a part of the arc-shaped protrusion 152 protrudes from the opening of the placement groove 142. The protruding part of the arc-shaped protrusion 152 is an arc surface, and the arc length corresponding to the arc surface is a minor arc. Four positioning grooves 16 for the elastic clip 15 to be clamped into are evenly provided on the inner wall of the box body 1. When the support plate 14 is rotated to a horizontal or vertical state, it can be snapped into the corresponding positioning groove 16 to limit the rotation of the support plate 14; and the indicator plate 41 can be rotated downward to a vertical state after the support plate 14 rotates (and fixed by a structure similar to the limit plate 111 installed on the inner wall of the box body 1), and the control plate 43 can be rotated to a state parallel to the vertical inner wall of the box body 1 and fixed when the indicator plate 41 is in the vertical downward state.

[0041] Reference Figure 11 and Figure 13 A blocking assembly 6 is provided in the box body 1, wherein the blocking assembly 6 includes a blocking plate 61 located above the protective cover 32, and vertical rods 62 that can slide up and down are slidably provided on the inner wall of the box body 1 along the vertical direction and are located on both sides of the protective plate 3. The two sides of the blocking plate 61 are respectively fixedly connected to the side surfaces of the two vertical rods 62 that are close to each other; an elastic reset member 64 that drives the vertical rod 62 to slide upward is provided in the box body 1, and a bending rod 63 facing the partition plate 11 is vertically fixed to the lower end of the vertical rod 62; The elastic return member 64 includes a second spring 641, a fixed block 643 fixed to the inner wall of the box body 1, and a protruding block 642 fixed to the outer periphery of the vertical rod 62. The fixed block 643 has a fixing hole for the vertical rod 62 to pass through and slide. The protruding block 642 is located above the fixed block 643. The two ends of the second spring 641 are respectively on the side surfaces of the protruding block 642 and the fixed block 643 that are close to each other. When it is rainy and humid outside, the indicator plate 41 is adjusted to a vertical downward position in advance, and the staff then overcomes the elastic force of the second spring 641 to press the blocking plate 61 downward, and then rotates the control plate 43 to the top of the bending rod 63, so that the lower side of the locking plate 54 can be pressed against the upper side of the bending rod 63. In this state, the blocking plate 61 moves downward and blocks the opening of the protective cover 32.

[0042] The implementation principle of the embodiment of this application is: Inside the distribution box, the wiring port 112 on the partition plate 11 facilitates the layout of the cables, and the clamping plate 51 and the elastic extrusion member 53 cooperate to stably clamp the wiring harness passing through the wiring port 112. The design of the clamping plate 51 not only ensures the fixation of the cables, but also enhances the tightness and protection of the clamping through the elastic pad 52 made of rubber. In addition, the linkage mechanism between the locking plate 54 and the control plate 43 further enhances the clamping stability and facilitates the layout operation of the cables. The design of the elastic clip 15 of the support plate 14 enables the support plate 14 to stably switch between horizontal and vertical states, providing a basis for the flexible rotation and fixation of the indicator plate 41. Under special weather conditions, the opening of the protective cover 32 is effectively blocked by the cooperation of the blocking plate 61, the vertical rod 62 and the elastic reset member 64, preventing the humid air from invading the equipment inside the distribution box.
