Abstract
Description
Technical Field
[0001] This application relates to the technical field of distribution boxes, and in particular to a comprehensive distribution box with a safety baffle. Background Technology
[0002] A distribution box is an electrical device used to distribute electrical energy and facilitate the opening and closing of circuits.
[0003] In related technologies, the distribution box includes a box body and a door. A receiving groove is provided on the side of the box body, and the boxes are rotatably connected. The door can cover the receiving groove. Copper busbars and electrical components are housed within the receiving groove. The copper busbars are exposed to the external environment and are energized with switches. A safety baffle is fixedly installed inside the box to block the copper busbars and switches, improving the safety of operators.
[0004] When the switch needs maintenance, the safety barrier is fixed to the cabinet, so the staff cannot immediately access the switch. The staff must first remove the safety barrier, which increases the maintenance time. Summary of the Invention
[0005] To improve the efficiency of maintenance work, this application provides an integrated distribution box with a safety baffle.
[0006] This application provides a comprehensive distribution box with a safety baffle, which adopts the following technical solution: A comprehensive distribution box with safety baffles includes a box body. A receiving groove is provided on one side of the box body, and a copper busbar is disposed within the receiving groove. A switch is electrically connected to the end face of the copper busbar facing the opening of the receiving groove. The box body is provided with a first safety baffle for partially blocking the copper busbar and a second safety baffle for blocking the switch. The receiving groove includes two parallel fixing surfaces, and a second locking structure connecting the fixing surfaces and the second safety baffle is provided between them. The second locking structure includes a fixing plate disposed on the fixing surface, located between the second safety baffle and a mounting bracket. A first fixing block is disposed on the end face of the fixing plate away from the mounting bracket, and a second fixing block is disposed above the first fixing block. The second safety baffle has insertion holes for the first and second fixing blocks. When the second safety baffle blocks the switch, the upper end face of the first fixing block abuts against the inner wall of the insertion hole.
[0007] By adopting the above technical solution, a first safety baffle is set to shield the copper busbar, reducing the risk of workers accidentally touching the copper busbar and improving the safety of workers when performing maintenance inside the enclosure; a second safety baffle is set to shield the switch, preventing workers from accidentally touching the switch; when the switch needs to be repaired, the second safety baffle is driven to move upward so that the inner wall of the socket no longer contacts the upper surface of the first fixing block, and then the second safety baffle is driven to move away from the operating frame so that both the first and second fixing blocks pass through the socket, separating the second safety baffle from the fixing seat. When the second safety baffle no longer shields the switch, workers can perform maintenance work on the switch, improving the efficiency of worker maintenance.
[0008] Optionally, a fixed chamfer is provided on the second fixing block, and the fixed chamfer is located at the junction of the side of the second fixing block facing the operating frame and the upper end surface of the second fixing block.
[0009] By adopting the above technical solution, a fixed chamfer is set. When the inner wall of the socket contacts the inclined surface of the fixed chamfer, the second safety baffle slides downward and is supported on the first fixed block.
[0010] Optionally, the second safety barrier is made transparent.
[0011] By adopting the above technical solution, staff can directly observe the switch through the second safety barrier to determine whether the switch is damaged.
[0012] Optionally, an operating component connecting the first safety baffle and the second safety baffle is provided. The operating component includes an operating plate disposed below the first safety baffle. Two operating seats are disposed on the end face of the operating plate away from the mounting frame. The two operating seats are horizontally distributed. Each of the end faces of the two operating seats that are close to each other has an operating hole in the shape of a vertical waist. An operating rod passes through the operating hole. The operating rod is slidably disposed in the operating hole in the vertical direction. An operating strip is sleeved on the operating rod. The lower end face of the operating strip is fixedly connected to the upper end face of the second safety baffle.
[0013] By adopting the above technical solution, the second safety baffle is driven to rotate, causing it to rotate along the axis of the operating rod, so that the second safety baffle no longer obstructs the switch, allowing the operator to maintain the switch; the first safety baffle and the second safety baffle are connected as one unit, and the first safety baffle is installed into the box, thus realizing the installation of the second safety baffle without the need for additional manual operation, eliminating the need for the installation of the second installation baffle and saving installation time.
[0014] Optionally, the first safety baffle is provided with a third locking structure for connecting the first safety baffle and the second safety baffle. The third locking structure includes a first operating block disposed on the side of the first safety baffle away from the mounting bracket, and a second operating block disposed on the upper end surface of the first operating block. When the second safety baffle rotates, the first operating block and the second operating block can pass through the insertion hole.
[0015] By adopting the above technical solution, after the second safety baffle is rotated, both the first and second operating blocks pass through the socket, so that the second safety baffle is supported on the first operating block and fixed, thereby facilitating the maintenance of the switch by the staff.
[0016] Optionally, the operating hole includes an arc surface, the operating rod is fitted with a roller, the outer circumference of the roller is provided with an operating ring groove, the inner diameter of the operating ring groove is the same as the diameter of the arc surface, and the roller can move vertically within the operating hole.
[0017] By adopting the above technical solution and setting rollers, the operating rod and the inner wall of the operating hole are protected; when the operating rod moves in the vertical direction, the wear of the inner wall of the operating hole can be reduced.
[0018] Optionally, the operating lever includes a first operating shaft, and a second operating shaft is provided on both ends of the first operating shaft. An operating ring groove is formed on the outer circumferential surface of the second operating shaft, and a retaining spring is provided in the operating ring groove. When one end of the roller is in contact with the first operating shaft, the other end of the roller is coplanar with the inner wall of the operating ring groove near the first operating shaft.
[0019] By adopting the above technical solution, the roller is limited by the first operating shaft and the retaining ring, so that the roller cannot move along the axial direction of the first operating shaft, thus limiting the roller.
[0020] Optionally, a limiting groove is formed on the outer circumferential surface of the second operating shaft, the limiting groove passing through the second operating shaft in a direction away from the first operating shaft, and a limiting block is provided on the roller that is inserted into the limiting groove, the limiting block being slidably disposed in the limiting groove.
[0021] By adopting the above technical solution, the limiting block is embedded in the limiting groove. When the operating lever rotates, it can drive the roller to rotate together, so that the operating lever and the roller will not rotate together, thus reducing the wear of the operating lever.
[0022] Optionally, the operating seat has a punch hole on the end face facing the operating bar for the roller to pass through. The upper end of the operating hole is connected to the punch hole. The diameter of the punch hole is the same as the inner diameter of the operating ring groove. A rubber block is provided in the punch hole, and a slot for the roller to enter is provided on the rubber block.
[0023] By adopting the above technical solution, the rubber block is installed into the punch hole, so that the rubber block partially blocks the punch hole and prevents the roller from detaching from the punch hole.
[0024] Optionally, the inner wall of the punch is provided with a groove, and the outer surface of the rubber block is provided with a protrusion embedded in the groove.
[0025] By adopting the above technical solution, the protrusion is embedded in the groove to fix the rubber block, making it difficult for the rubber block to fall out of the punch hole.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. A first safety baffle is installed to shield the copper busbar, reducing the risk of accidental contact by workers and improving safety during internal maintenance. A second safety baffle is installed to shield the switch, preventing accidental contact. When the switch needs maintenance, the second safety baffle is moved upwards so that the inner wall of the socket no longer contacts the upper surface of the first fixing block. Then, the second safety baffle is moved away from the operating frame so that both the first and second fixing blocks pass through the socket, separating the second safety baffle from the fixing base. Once the second safety baffle no longer shields the switch, workers can perform maintenance, improving maintenance efficiency. 2. The first safety baffle and the second safety baffle are integrated into one unit. During installation, only the first safety baffle needs to be fixed to complete the installation of the second safety baffle. There is no need to install the first safety baffle and the second safety baffle separately, which reduces the installation steps. Attached Figure Description

Furthermore, both the first safety baffle 4 and the second safety baffle 5 are transparent, thereby facilitating the observation of the copper busbar 2 or the switch 3 by personnel.
[0046] The implementation principle of Example 1 is as follows: When switch 3 needs maintenance, the second safety baffle 5 is driven to move, so that the first fixing block 72 and the second fixing block 73 are disengaged from the socket 51, so that the second safety baffle 5 is separated from the second locking structure 7, so that the second safety baffle 5 no longer blocks switch 3, making it easier for staff to carry out maintenance work.
[0047] Example 2 Reference Figure 6 The difference between this embodiment and Embodiment 1 is that two operating components 8 are provided between the first safety baffle 4 and the second safety baffle 5 to connect the two.

[0053] Reference Figure 6 and Figure 7 When switch 3 needs to be repaired, first drive the second safety baffle 5 to rise, then drive the second safety baffle 5 to rotate, so that the first fixing block 72 and the second fixing block 73 are disengaged from the socket 51. Then, insert the first operating block 91 and the second operating block 92 into the socket 51. Finally, drive the second safety baffle 5 to fall, so that the upper end face of the first operating block 91 abuts against the inner wall of the socket 51.
[0054] The implementation principle of Example 2 is as follows: by adjusting the position of the operating rod 83 in the operating hole 821, the second safety baffle 5 and the operating bar 84 are rotated together along the axis of the operating rod 83, so that the first operating block 91 and the second operating block 92 are inserted into the insertion hole 51, and then the operating rod 83 is driven to descend so that the second safety baffle 5 is supported on the first operating block 91 and the second safety baffle 5 is fixed.
[0055] Example 3 Reference Figure 8 and Figure 9 The difference between this embodiment and Embodiment 2 is that the operating lever 83 includes a first operating shaft 831 and a second operating shaft 832. A positioning groove 8311 is formed on the circumferential surface of the first operating shaft 831, extending through the first operating shaft 831 along its axial direction. A through hole 841 is formed on the operating bar 84, through which the first operating shaft 831 and the second operating shaft 832 can pass. A positioning bar 842, which can be inserted into the positioning groove 8311, is fixedly connected to the inner wall of the through hole 841. When the positioning bar 842 is inserted into the positioning groove 8311, the operating bar 84 and the operating lever 83 can rotate synchronously.

The first operating shaft 831 and the second operating shaft 832 are arranged coaxially.
[0057] Reference Figure 8 and Figure 9 The second operating shaft 832 has a limiting groove 8321 on its outer circumferential surface, which extends through the first operating shaft 831 in a direction away from it. The second operating shaft 832 also has a mounting ring groove 8322 on its outer circumferential surface, and a retaining ring 8323 is installed in the mounting ring groove 8322.
[0058] Reference Figure 8 and Figure 9 Both operating seats 82 have punched holes 822 on their adjacent end faces, and the upper end of the operating hole 821 communicates with the punched hole 822. The operating hole 821 includes an arc surface 823, and the inner diameter of the punched hole 822 is larger than the diameter of the arc surface 823. The inner wall of the punched hole 822 has a groove 824.

The limiting block 102 can be embedded into a limiting groove 8321 and can slide within the limiting groove 8321 along the axis of the second operating shaft 832. When one end face of the roller 10 abuts against the end face of the first operating shaft 831, the end face of the roller 10 away from the first operating shaft 831 is coplanar with the inner wall of the mounting ring groove 8322 near the first operating shaft 831.
[0060] Reference Figure 8 and Figure 9 An operating ring groove 103 is provided on the outer circumference of the roller 10. The outer diameter of the roller 10 is the same as the inner diameter of the punch 822, and the inner diameter of the operating ring groove 103 is the same as the diameter of the arc surface 823.
[0061] Reference Figure 8 and Figure 9 A rubber block 825 is disposed within the punch hole 822, and a protrusion 826 is fixedly connected to the outer surface of the rubber block 825, which can be embedded into the punch hole 822. A slot 827 is provided at one end of the rubber block 825 facing the arc surface 823, through which the roller 10 can enter. The minimum distance from the axis of the punch hole 822 to the rubber block 825 is the same as the radius of the arc surface 823.
[0062] The implementation principle of Example 3 is as follows: When driving the second safety baffle 5 to rotate or driving the operating rod 83 to move in the operating hole 821, the roller 10 contacts the inner wall of the operating hole 821, making the second operating shaft 832 less prone to wear.
