Description

Technical Field

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

[0002] Distribution boxes, as electrical equipment, play a crucial role in fixed locations due to their compact size, simple installation, and unique technical performance. They serve as the main circuit distribution box for users, rationally distributing electrical energy and facilitating circuit opening and closing operations. Distribution boxes are versatile, adaptable to various locations, and offer stable and reliable operation. They also boast high space utilization, require minimal floor space, and contribute to environmental friendliness.

[0003] In related technologies, a distribution box includes a box body and a door mounted on the box body. Several support plates are fixed horizontally inside the box body, and related electrical components are fixed to the upper surface of the support plates with screws. To visually display the operating status of the electrical components, an indicator assembly is added inside the box, including an indicator plate fixed inside the box body and several indicator lights. These indicator lights are connected to the electrical components via complex cables. When the status of the electrical components changes, the indicator lights display different colors to provide immediate 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. This is especially true when the internal space of the enclosure is relatively narrow, which severely affects the installation efficiency. This not only increases the difficulty of construction but may also cause safety hazards due to improper operation, indicating room for improvement. Summary of the Invention

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

[0006] The present application provides a convenient maintenance distribution box using the following technical solution:

[0007] A power distribution box for easy maintenance includes a box body and a door installed on the box body. A partition plate is fixedly installed in the middle of the box body along the vertical direction, and several heat dissipation vents are opened on the vertical side of the box body. A support plate is installed on the vertical inner wall of the box body. A limiting plate opposite to the support plate is fixedly installed on the side of the partition plate facing the support plate. An indicator plate is provided inside the box body, and several indicator lights are fixedly installed on the indicator plate. A rotating shaft is fixedly installed in the vertical direction on the support plate and rotatably connected to one side of the indicator plate. The other side of the support plate can rotate around the rotating shaft to abut against the limiting plate. A locking member is provided inside the box body to detachably install the end of the indicator plate away from the support plate onto the limiting plate.

[0008] By adopting the above technical solution, when maintenance or cable connection is required, operators can easily rotate the indicator panel around the pivot to a more spacious and easily accessible position simply by unlocking the locking mechanism. This greatly simplifies the workflow and reduces operational difficulty. After maintenance or cable connection is completed, operators can easily lock the indicator panel back into place to ensure stable and reliable operation. This design not only improves work efficiency but also enhances operational safety, making the maintenance and management of the distribution box easier and more efficient.

[0009] Optionally, the locking component includes a locking rod, a locking handle fixed to one end of the locking rod, and a locking baffle fixed to the other end of the locking rod. The end of the indicator plate away from the support plate has 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 near the door, and the locking baffle is located on the side of the indicator plate away from the door. When the indicator plate and the limiting plate are in contact, the locking baffle can rotate with the locking rod to the side of the limiting plate away from the door.

[0010] By adopting the above technical solution, the locking rod passes through the locking through-hole of the indicator plate and is fixed by the locking handle and locking baffle. This allows the operator to easily control the locking rod by rotating the locking handle, thus 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, facilitating operation from the outside, while the locking baffle rotates with the locking rod to the side of the limit plate away from the door, achieving a stable fixing effect. 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.

[0011] Optionally, a protective plate for blocking several heat dissipation vents is fixed on the inner wall of the box, and an air inlet hole overlapping the heat dissipation vent is opened on the protective plate; an upward-opening protective cover is fixed on the opening edge of the air inlet hole away from the heat dissipation vent, and a downward-opening drain cover is fixed on the opening edge of the heat dissipation vent away from the protective plate.

[0012] By adopting the above technical solution, the protective plate and its air intake design not only ensure air circulation and achieve heat dissipation, but also effectively prevent external debris or small animals from entering the distribution box, thus improving the safety and stability of the distribution box. At the same time, the protective cover and the drainage cover further enhance the protective effect. The protective cover opens upwards to prevent rainwater or other liquids from splashing into the air intake from above, while the drainage cover opens downwards to guide the airflow into the distribution box, while preventing debris or small animals from entering through the ventilation opening.

[0013] Optionally, the partition plate has a wiring port, and two clamping plates are slidably mounted on the partition plate in the vertical direction towards the support plate. The two clamping plates are located above and below the wiring port, respectively. An arc-shaped notch is provided on the side of the two clamping plates that are close to each other. An elastic pad is fixed on the inner wall of the arc-shaped notch. An elastic extrusion member is fixed on the partition plate to make the two clamping plates slide towards each other.

[0014] By adopting the above technical solution, the connection port on the separator plate facilitates cable insertion, while the upper and lower clamping plates securely hold the cable, preventing it from loosening or falling off. The arc-shaped notches on the clamping plates, in conjunction with the elastic pads, can accommodate cables of different diameters and provide effective cushioning and protection to prevent cable damage. Simultaneously, the elastic compression element allows the two clamping plates to automatically slide towards each other and tightly clamp the cable, eliminating the need for manual operation and greatly improving wiring efficiency and stability.

[0015] Optionally, a positioning rod is fixed on the side of the two clamping plates that are far apart from each other. The elastic compression member includes a first spring and a limiting block fixed on the partition plate. The limiting block has a limiting hole for the positioning rod to pass through. The two ends of the first spring are fixedly connected to the limiting block and the side of the clamping plate that are close to each other.

[0016] By adopting the above technical solution, the first spring, as the core component of the elastic extrusion member, not only provides continuous extrusion force to the clamping plate, ensuring stable clamping of the cable, but also absorbs and mitigates external impact forces on the cable to a certain extent through its elastic properties, protecting the cable from damage. Simultaneously, the two ends of the first spring are fixedly connected to the limiting block and the clamping plate respectively, ensuring stable transmission of spring force and improving the reliability and durability of the clamping mechanism.

[0017] Optionally, a locking plate is slidably mounted on the partition plate, located on the side of the clamping plate near the door. The locking plate has a locking notch on its side 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 to the upper edge of the indicator plate, and an adjusting member is provided for adjusting the rotation of the control plate. The control plate can be rotated to a horizontal state and fixed. In this state, when the indicator plate is fixed on the limiting plate, the control plate can press against the abutment plate, so that the edges of the two clamping plates near the door are engaged together into the locking notch.

[0018] By adopting the above technical solution, the design of the locking plate and locking notch allows the two clamping plates to automatically engage with the locking notch through the squeezing action of the control plate when the indicator plate is fixed, thus achieving a secure lock on the cable. This automatic locking mechanism not only simplifies the operation steps and improves work efficiency, but also effectively prevents the cable from loosening or falling off due to human negligence or external interference. Simultaneously, the cooperation between the control plate and the adjusting components allows operators to flexibly adjust the position and state of the control plate according to actual needs, further enhancing the flexibility and convenience of operation.

[0019] Optionally, a diagonal brace is hinged to the extension rod, and a conical block is fixed to the end of the diagonal brace away from the extension rod. An abutment groove is provided on the side of the abutment plate near the locking plate for the conical block to rotate and engage.

[0020] By adopting the above technical solution, the connection stability between the extension rod and the abutment plate is enhanced when the conical block is interference-fitted into the abutment groove.

[0021] Optionally, the conical block can be inserted between the two clamping plates when the diagonal brace rotates away from the abutment plate.

[0022] By adopting the above technical solution, when laying out cables and needing to pass through the connection port, the locking plate is slid away from the clamping plate in advance to release the locking of the clamping plate. Then, the diagonal brace is rotated away from the abutting 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, which makes it easy for the cable to pass through the connection port.

[0023] Optionally, the support plate is rotatably connected to the inner wall of the box, and the support plate is provided with an elastic snap-fit ​​component. The inner wall of the box is evenly provided with a plurality of positioning grooves for the elastic snap-fit ​​component to snap into. The indicator plate can rotate downward to a vertical state and be fixed after the support plate rotates. When the indicator plate is in a vertical downward state, the control plate can rotate to a state parallel to the vertical inner wall of the box and be fixed.

[0024] By adopting the above technical solution, the rotating connection between the support plate and the inner wall of the box, as well as the cooperative design of the elastic snap-fit ​​and the positioning groove, allows the support plate and the indicator plate to rotate flexibly and be 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 with the support plate to a vertically downward position, the control plate can also rotate accordingly to a position parallel to the vertical inner wall of the box and be fixed. This not only facilitates cable connection and maintenance work for operators, but also effectively utilizes the internal space of the distribution box, improving space utilization.

[0025] Optionally, the housing is provided with a sealing plate located above the protective cover. Vertical rods that can slide up and down are slidably arranged on both sides of the protective plate on the inner wall of the housing. The two sides of the sealing plate are fixedly connected to the sides of the two vertical rods that are close to each other. The housing is provided with an elastic reset member that drives the vertical rods to slide upward. A bent rod facing the partition plate is vertically fixed at the lower end of the vertical rod. When the indicator plate is in the vertically downward state, the control plate can rotate to the state where the upper side of the bent rod abuts after the bent rod moves down with the vertical rod. In this state, the sealing plate moves down to seal the opening of the protective cover.

[0026] By adopting the above technical solution, in rainy or humid weather, operators can pre-adjust the indicator plate to a vertically downward position and press the sealing plate down against the elastic force of the spring-loaded reset component. Then, the control plate is rotated above the bending rod, causing the lower side of the locking plate to tightly abut against the upper side of the bending rod. At this point, the sealing plate moves down and completely seals the opening of the protective cover. This design effectively prevents rainwater and moisture from entering the distribution box from the protective cover, avoiding problems such as short circuits or equipment damage caused by a humid environment, and ensuring the safe and stable operation of the distribution box and its internal equipment.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When maintenance or cable connection is required, operators can easily rotate the indicator panel around the pivot to a more spacious and easily accessible position by simply unlocking the locking mechanism, greatly simplifying the workflow and reducing operational difficulty. After maintenance or cable connection is completed, operators can easily lock the indicator panel back into place to ensure stable and reliable operation. This design not only improves work efficiency but also enhances operational safety, making the maintenance and management of the distribution box easier and more efficient.

[0029] 2. In rainy or humid weather, the operator can pre-adjust the indicator plate to a vertically downward position and press the sealing plate down against the elastic force of the spring-loaded reset component. Then, rotate the control plate above the bending rod, ensuring the lower side of the locking plate is firmly against the upper side of the bending rod. At this point, the sealing plate will move down and completely seal the opening of the protective cover. This design effectively prevents rainwater and moisture from entering the distribution box from the protective cover, avoiding short circuits or equipment damage caused by a humid environment, and ensuring the safe and stable operation of the distribution box and its internal equipment.

Detailed Implementation

[0045] The present application will be further described in detail below with reference to all the accompanying drawings.

[0046] Example 1:

[0047] Reference Figure 1 , Figure 2 and Figure 3 A power distribution box that is easy to maintain includes a box body 1 and a door 2 installed on the box body 1. One side edge of the door 2 is hinged to the edge of the box body 1, and the other side of the door 2 is detachably connected to the box body 1 by a conventional lock structure. A partition plate 11 is fixed in the middle of the box body 1 along the vertical direction.

[0048] A heat dissipation vent 12 is provided on the vertical side of the housing 1. A protective plate 3 is fixed to the inner wall of the housing 1 by screws, covering the outside of several heat dissipation vents 12. An air inlet 31 overlapping with the heat dissipation vents 12 is provided on the protective plate 3. An upward-opening protective cover 32 is fixed on the opening edge of the air inlet 31 away from the heat dissipation vent 12. A downward-opening drain cover 13 is fixed on the opening edge of the heat dissipation vent 12 away from the protective plate 3.

[0049] Refer to 3 and Figure 4 A support plate 14 is fixed to the vertical inner wall of the box 1 by screws. A limiting 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. An indicator assembly 4 is provided inside the box 1. The indicator assembly 4 includes an indicator plate 41 installed in the box 1 in the horizontal direction, and several indicator lights 411 are fixed on the indicator plate 41.

[0050] A rotating shaft 141 is fixed on the support plate 14 along the vertical direction and is rotatably connected to one side of the indicator plate 41. The other side of the support plate 14 can rotate around the axis of the rotating shaft 141 to abut against the limiting plate 111. The housing 1 is provided with a locking member 42 that can be detachably installed on the limiting plate 111 on the side of the indicator plate 41 away from the support plate 14.

[0051] Reference Figure 4 and Figure 5 The locking component 42 includes a locking rod 421, a locking handle 422 fixed to one end of the locking rod 421, and a locking baffle 423 fixed to the other end of the locking rod 421. 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 near the door 2, and the locking baffle 423 is located on the side of the indicator plate 41 away from the door 2.

[0052] When it is necessary to fix the indicator plate 41, rotate the indicator plate 41 around the pivot 141 in a direction away from the door 2, so that the end of the indicator plate 41 away from the support plate 14 abuts against the limiting plate 111. Then rotate the locking handle 422 to rotate the locking folding plate 423 with the locking rod 421 to the side of the limiting plate 111 away from the 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 on the indicator plate 41, and then rotate the indicator plate 41 towards the door 2. Then the cable can be connected.

[0053] The implementation principle of this application embodiment is as follows:

[0054] The enclosure 1 effectively divides the internal space using partition plates 11. It also incorporates a structure combining heat dissipation vents 12 and a protective plate 3, ensuring heat dissipation while preventing the entry of foreign objects through the design of the protective cover 32 and the drainage cover 13. Furthermore, the innovative indicator plate 41 design within the enclosure 1, through the cooperation of the support plate 14, the limiting plate 111, and the locking element 42, allows for flexible rotation and fixation of the indicator plate 41. When maintenance or cable connection is required, the operator can easily unlock the indicator plate 41, rotate it to a convenient position, and then fix it back in its original position after the operation is complete.

[0055] Example 2:

[0056] Reference Figure 6 and Figure 7The difference between this embodiment and Embodiment 1 is that the partition plate 11 has a wiring port 112, and the housing 1 has a clamping assembly 5. The clamping assembly 5 includes two clamping plates 51 that slide vertically on the side of the partition plate 11 facing the support plate 14. The two clamping plates 51 are located above and below the wiring port 112, respectively. The sides of the two clamping plates 51 that are close to each other have an arc-shaped notch 511. The inner wall of the arc-shaped notch 511 is fixed with an elastic pad 52 made of rubber by glue. The partition plate 11 is fixed with an elastic extrusion member 53 that makes the two clamping plates 51 slide towards each other.

[0057] Reference Figure 7 Positioning rods 512 are fixed on the sides of the two clamping plates 51 that are far apart 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 has a limiting hole for the positioning rod 512 to pass through. The two ends of the first spring 531 are fixedly connected to the limiting block 532 and the sides of the clamping plates 51 that are close to each other.

[0058] Reference Figure 8 and Figure 9 The partition plate 11 is slidably provided with a locking plate 54 located on the side of the clamping plate 51 near the door 2. The locking plate 54 has a locking notch 541 on the side facing the clamping plate 51. An extension rod 55 is fixed on the side of the locking plate 54 away from the clamping plate 51. An abutment plate 56 is fixed at the end of the extension rod 55.

[0059] A control plate 43 is hinged to the upper edge of the indicator plate 41, and an adjusting member 44 is provided for adjusting the rotation of the control plate 43. The adjusting member 44 is a butterfly bolt 441. Tightening or loosening the hinge between the control plate 43 and the indicator plate 41 can adjust the state of the control plate 43. The control plate 43 can be rotated to a horizontal state and fixed.

[0060] When the indicator plate 41 is fixed on the limiting plate 111, the horizontal control plate 43 can press against the abutment plate 56, so that the two clamping plates 51 near the edge of the door 2 are inserted into the locking notch 541, thereby enhancing the clamping stability of the two clamping plates 51 on the wire harness passing through the terminal 112; there is a gap between the indicator plate 41 and the partition plate 11, which are parallel to the side wall of the partition plate 11, that is, when the indicator plate 41 is turned in or out, the control plate 43 will not collide or bump against the side wall of the partition plate 11, and the two will not interfere with each other.

[0061] Reference Figure 10An extension rod 55 is hinged with a diagonal brace 57, wherein a conical block 571 is fixed at the end of the diagonal brace 57 away from the extension rod 55, which can be fastened with bolts to adjust and fix the rotation angle of the diagonal brace 57; an abutment plate 56 has an abutment groove 561 on its side near the locking plate 54 for the conical block 571 to rotate and engage; when the conical block 571 is interference-fitted into the abutment groove 561, the connection stability between the extension rod 55 and the abutment plate 56 is enhanced.

[0062] When laying out cables and needing to pass through the connector 112, the locking plate 54 is slid away from the clamping plate 51 to release the locking of the clamping plate 51. Then, the diagonal brace 57 is rotated away from the abutting 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 in opposite directions under the action of the conical block 571, which facilitates the cable laying out.

[0063] Reference Figure 11 and Figure 12 The support plate 14 is rotatably connected to the inner wall of the box 1. The support plate 14 is provided with an elastic snap-fit ​​component 15, which includes a compression spring 151 and an arc-shaped protrusion 152. The support plate 14 is provided with a placement groove 142 for the compression spring 151 and the arc-shaped protrusion 152 to be placed. The compression spring 151 presses one side of the arc-shaped protrusion 152, causing a part of the arc-shaped protrusion 152 to protrude out of 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 are evenly provided on the inner wall of the box 1 for the elastic snap-fit ​​component 15 to be snapped into.

[0064] When the support plate 14 rotates to a horizontal or vertical position, it can be engaged in the corresponding positioning groove 16 to limit the rotation of the support plate 14; and the indicator plate 41 can rotate downward to a vertical position after the support plate 14 rotates (and is fixed by a structure similar to the limiting plate 111 installed on the inner wall of the box 1). When the indicator plate 41 is in a vertical downward position, the control plate 43 can rotate to a position parallel to the vertical inner wall of the box 1 and be fixed.

[0065] Reference Figure 11 and Figure 13 The housing 1 is equipped with a sealing assembly 6, which includes a sealing plate 61 located above the protective cover 32. Vertical rods 62, which are located on both sides of the protective cover 3 and can slide up and down, are slidably arranged on the inner wall of the housing 1. The two sides of the sealing plate 61 are fixedly connected to the sides of the two vertical rods 62 that are close to each other. The housing 1 is equipped with an elastic reset member 64 that drives the vertical rods 62 to slide upward. The lower end of the vertical rods 62 is vertically fixed with a bent rod 63 facing the partition plate 11.

[0066] The elastic reset component 64 includes a second spring 641, a fixing block 643 fixed on the inner wall of the housing 1, and a protruding block 642 fixed on the outer periphery of the vertical rod 62. The fixing block 643 has a fixing hole through which the vertical rod 62 passes and slides. The protruding block 642 is located above the fixing block 643. The two ends of the second spring 641 are respectively close to the sides of the protruding block 642 and the fixing block 643.

[0067] When it is rainy and humid outside, the indicator plate 41 is adjusted to a vertical downward position in advance. Then, the staff overcomes the elastic force of the second spring 641 to press down the sealing plate 61. Then, the control plate 43 is rotated 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 sealing plate 61 moves down and seals the opening of the protective cover 32.

[0068] The implementation principle of this application embodiment is as follows:

[0069] Inside the distribution box, the wiring port 112 on the partition plate 11 facilitates cable layout. The clamping plate 51 and the elastic pressing member 53 work together to stably clamp the wires passing through the wiring port 112. The clamping plate 51 not only ensures cable fixation but also enhances the tightness and protection of the clamping through the elastic rubber pad 52. Furthermore, the linkage mechanism between the locking plate 54 and the control plate 43 further enhances clamping stability and facilitates cable layout. The elastic snap-fit ​​member 15 of the support plate 14 allows it to stably switch between horizontal and vertical positions, providing a basis for the flexible rotation and fixation of the indicator plate 41. Under special weather conditions, the sealing plate 61, in conjunction with the vertical rod 62 and the elastic reset member 64, effectively seals the opening of the protective cover 32, preventing humid air from damaging the equipment inside the distribution box.
