[0008] Preferably, the width of the strip rod B matches the slot A, and a through hole is provided on the top of the box body, through which the rotating cylinder and the strip rod A move.

[0009] Preferably, the outer wall of the connecting plate is provided with a receiving groove, the outer wall of the rotating shaft is fixedly fitted with a connecting rod A, the end of the connecting rod A away from the rotating shaft is fixedly connected to an installation block, the lower side of the installation block is fitted with a roller, the side of the box is provided with a T-shaped groove, the inner wall of the T-shaped groove is slidably connected to a T-shaped block, the outer side of the T-shaped block is fixedly connected to a connecting rod B, and the other end of the connecting rod B is fixedly connected to a triangular block.

[0010] Preferably, the end of the connecting rod A that is connected to the rotating shaft is located inside the receiving groove, and the triangular block is located in the rotation path of the roller.

[0011] Preferably, a spring B is fixedly connected to the bottom of the T-shaped groove, and the upper end of the spring B is fixedly connected to the T-shaped block.

[0012] Preferably, a fixing rod B is fixedly connected to the inner wall of the box, a movable plate is slidably connected to the outer wall of the fixing rod B, an assembly plate is fixedly connected to the front side of the movable plate, a connecting rod A is fixedly sleeved on the outer wall of the mounting rod, a connecting rod B is hinged to the other end of the connecting rod A, and the other end of the connecting rod B is hinged to the bottom of the movable plate.

[0014] The advantages of this application are: (1) This application realizes the switching between maintenance mode and observation mode of protective glass: When maintenance is required, only the height of the L-shaped plate needs to be adjusted so that the rotating drum and the strip rod B are engaged. The door can be rotated by the transmission chain of the toothed ring, toothed plate and rotating drum to drive the mounting rod to rotate, automatically flipping open the protective glass to expose the internal electrical components. When only regular observation is required, the L-shaped plate is kept at the initial height so that the rotating drum and the strip rod B are separated. Rotating the door will not touch the protective glass. Maintenance personnel can safely observe the equipment status through the glass, which not only improves the convenience of maintenance, but also ensures the safety of daily inspection.

[0015] (2) When the door of this application is opened to a certain angle, after the roller passes over the inclined surface of the triangular block, the triangular block is reset under the action of the spring. Its vertical surface and the roller form a one-way block to prevent the door from accidentally returning to its original position, so that maintenance personnel can free their hands and focus on internal operations. When it is necessary to close, the restriction can be released by simply pressing the triangular block. This effectively solves the problem that the door of the traditional branch box is easily blown by the wind or accidentally closed during maintenance, and significantly improves the convenience and safety of maintenance operations.

[0016] (3) The rotation of the mounting rod of this application simultaneously drives the connecting rod A and the connecting rod B to drive the moving plate to slide forward along the fixed rod B, so that the electrical components installed on the mounting plate automatically move towards the box door, shortening the operating distance between the maintenance personnel and the components, reducing the extent of the body probing into the box, providing more operating space for the use of tools, and reducing the difficulty of maintenance.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0020] Example 1, as Figures 1-8 As shown, a high-safety high-voltage cable branch box that is easy to maintain includes a box body 1. A rotating shaft 2 is rotatably connected to the front side of the inside of the box body 1. A connecting plate 3 is fixedly sleeved on the outer wall of the rotating shaft 2. A box door 4 is fixedly connected to the inner side of the connecting plate 3. The top of the rotating shaft 2 rotates through the upper end of the housing 1 and is fixedly fitted with a movable rod 51. A groove 52 is provided in the middle of the movable rod 51. A fixed rod A53 is fixedly connected to the top of the housing 1. An L-shaped plate 54 is slidably connected to the outer wall of the fixed rod A53. A rotating cylinder 55 is rotatably connected to the inner side of the L-shaped plate 54. A toothed ring 56 is rotatably connected to the upper end of the housing 1. A toothed plate 57 meshes with the side of the toothed ring 56. A round shaft 58 is rotatably connected to the upper end of the toothed plate 57. The toothed plate 57 is slidably connected to the top of the housing 1 via a slide rail. Shaft 58 is slidably connected to the inner wall of slide groove 52. The inner wall of rotating cylinder 55 is provided with slot A59. The inner wall of toothed ring 56 is provided with slot B. The outer wall of rotating cylinder 55 is fixedly connected with strip rod A510. Strip rod A510 is slidably connected inside slot B. The inner wall of box 1 is rotatably connected with mounting rod 511. Mounting frame 512 is fixedly sleeved on the outer wall of mounting rod 511. Protective glass 513 is fixedly connected to the inner side of mounting frame 512. Strip rod B521 is fixedly connected to the upper outer wall of mounting rod 511. The outer wall of the L-shaped plate 54 is equipped with an adjusting member for adjusting the height of the L-shaped plate 54, and the outer wall of the mounting rod 511 is equipped with a limiting member for limiting the position of the mounting rod 511.

[0021] The adjusting component includes a positioning rod 514, a round block 515, a spring A516, and two positioning holes 517. The positioning rod 514 slides through the lower side of the L-shaped plate 54. The round block 515 is fixedly connected to the end of the positioning rod 514 away from the housing 1. The spring A516 is fixedly connected between the round block 515 and the L-shaped plate 54. The two positioning holes 517 are opened on the outer wall of the housing 1. The adjusting component allows the operator to easily adjust the height of the L-shaped plate 54 according to actual maintenance needs. When it is necessary to inspect the inside of the housing 1, press the round block 515 to disengage the positioning rod 514 from the current positioning hole 517. After moving the L-shaped plate 54 up and down to the appropriate position, release the round block 515. The spring A516 returns to its original position and pushes the positioning rod 514 into the corresponding positioning hole 517, thereby fixing the L-shaped plate 54.

[0022] The limiting component includes a fixing block 518, a torsion spring 519, and a limiting rod 520. The fixing block 518 is fixedly sleeved on the outer wall of the mounting rod 511. The torsion spring 519 is fixedly connected between the inner wall of the housing 1 and the fixing block 518. The limiting rod 520 is fixedly connected to the inner wall of the housing 1, and the end of the limiting rod 520 away from the inner wall of the housing 1 is in contact with the inner side of the fixing block 518.

[0023] The width of the bar B521 matches the slot A59, so that after the bar B521 descends to a certain height, it can slide into the interior of the slot A59. The top of the housing 1 is provided with a through hole, through which the rotating cylinder 55 and the bar A510 move.

[0024] When the above equipment is used and maintenance is required inside the branch box, first operate the adjusting component, pull the round block 515, drive the positioning rod 514 to slide away from the box 1, stretch the spring A516, and make the positioning rod 514 disengage from the current positioning hole 517; then slide the L-shaped plate 54 along the fixed rod A53 to a lower height, release the round block 515, the spring A516 resets and pushes the positioning rod 514 into the corresponding positioning hole 517, thus completing the height fixation of the L-shaped plate 54; Meanwhile, the rotating cylinder 55 inside the L-shaped plate 54 will move downwards, so that the slot A59 on the inner wall of the rotating cylinder 55 is engaged with the strip rod B521 on the mounting rod 511. At this time, the box door 4 is rotated, and the box door 4 drives the rotating shaft 2 to rotate. The movable rod 51 at the top of the rotating shaft 2 rotates synchronously. The sliding groove 52 on the movable rod 51 drives the toothed plate 57 to slide horizontally through the round shaft 58. The toothed plate 57 meshes with the toothed ring 56 to make it rotate. The toothed ring 56 cooperates with the strip rod A510 on the outer wall of the rotating cylinder 55 through the slot B on the inner wall, driving the rotating cylinder 55 to rotate. The rotating cylinder 55 then drives the strip rod B521 to rotate through the slot A59, thereby driving the mounting rod 511 to rotate around its own axis. When the mounting rod 511 rotates, the fixing block 518 compresses the torsion spring 519, causing the mounting frame 512 and the protective glass 513 to flip away from the maintenance area. The protective glass 513 is fully opened, exposing the electrical components inside the branch box, which facilitates the inspection and maintenance operations of maintenance personnel. After maintenance, rotate the door 4 in the reverse direction. The rotating shaft 2 drives the movable rod 51 to rotate in the reverse direction. The toothed plate 57 pushes the toothed ring 56 to rotate in the reverse direction. The rotating cylinder 55 rotates in the reverse direction accordingly. Under the reset action of the torsion spring 519, the mounting rod 511 drives the protective glass 513 to rotate back to its original position. The fixing block 518 re-fits with the limit rod 520, limiting the position of the mounting rod 511. Finally, operate the adjusting component, pull the round block 515 to make the positioning rod 514 disengage from the positioning hole 517. Slide the L-shaped plate 54 upward along the fixing rod A53 to the initial height. Release the round block 515. The spring A516 resets and pushes the positioning rod 514 into the corresponding positioning hole 517, completing the position fixation of the rotating cylinder 55. At the same time, when no maintenance is required and only the door 4 is opened for observation, as long as the L-shaped plate 54 is kept at its initial height, the slot A59 on the inner wall of the rotating drum 55 is separated from the strip rod B521 on the mounting rod 511. When the door 4 is rotated, the rotating shaft 2 drives the movable rod 51 to rotate. Although the toothed plate 57 drives the toothed ring 56 and the rotating drum 55 to rotate, the mounting rod 511 will not rotate because the rotating drum 55 and the strip rod B521 are not engaged. The protective glass 513 remains closed, and maintenance personnel can observe the operating status of the internal electrical components through the protective glass 513. Routine inspections can be completed without opening the protective glass 513.

[0025] Example 2, as Figures 1-8 As shown, based on Embodiment 1, the outer wall of the connecting plate 3 is provided with a receiving groove 61, the outer wall of the rotating shaft 2 is fixedly fitted with a connecting rod A62, the end of the connecting rod A62 away from the rotating shaft 2 is fixedly connected to a mounting block 63, the lower side of the mounting block 63 is fitted with a roller 64, the side of the box 1 is provided with a T-shaped groove 65, the inner wall of the T-shaped groove 65 is slidably connected to a T-shaped block 66, the outer side of the T-shaped block 66 is fixedly connected to a connecting rod B67, and the other end of the connecting rod B67 is fixedly connected to a triangular block 68.

[0026] One end of the connecting rod A62 connected to the rotating shaft 2 is located inside the receiving groove 61, and the triangular block 68 is in the rotation path of the roller 64. When the roller 64 rotates with the connecting rod A62 to the inclined surface that contacts the triangular block 68, it will generate a pushing force on the triangular block 68 along the inclined surface, forcing the triangular block 68 to drive the T-shaped block 66 to slide along the T-shaped groove 65 in a direction away from the box 1.

[0027] A spring B69 is fixedly connected to the bottom of the T-slot 65. The upper end of the spring B69 is fixedly connected to the T-block 66. The spring B69 is designed so that after the roller 64 rotates away from the inclined surface of the triangular block 68 with the connecting rod A62, it can pull the T-block 66 along the T-slot 65 towards the housing 1 by its own elastic restoring force, thereby driving the triangular block 68 to return to its initial position so that it can make contact with the roller 64 again in the future.

[0028] When the above-mentioned equipment is used, when the door 4 is rotated outward, the rotating shaft 2 synchronously drives the connecting rod A62 to rotate around the center of the rotating shaft 2. After the roller 64 on the lower side of the mounting block 63 rotates at a certain angle, it will contact the inclined surface of the triangular block 68. At this time, the roller 64 continues to rotate, which will force the triangular block 68 to drive the T-shaped block 66 to slide downward along the T-shaped groove 65, and the spring B69 will be compressed. After the roller 64 completely passes the triangular block 68, the spring B69 elastically returns to its original position, pushing the T-shaped block 66 and the triangular block 68 to move upward to the initial position. At this time, if the door 4 is rotated in the opposite direction, the roller 64 will abut against the vertical surface of the triangular block 68, restricting the return of the door 4 and temporarily fixing the door 4. This makes it easier for maintenance personnel to operate the internal components with both hands, improving the convenience of maintenance. When the maintenance is completed and the door 4 needs to be closed, simply press down on the triangular block 68 to compress the spring B69, which will release the restriction on the roller 64 and allow the door 4 to be turned smoothly to the closed position.

[0029] Example 3, as Figures 1-8 As shown, based on Embodiment 2, a fixed rod B71 is fixedly connected to the inner wall of the box 1, a movable plate 72 is slidably connected to the outer wall of the fixed rod B71, an assembly plate 73 is fixedly connected to the front side of the movable plate 72, a connecting rod A74 is fixedly sleeved on the outer wall of the mounting rod 511, a connecting rod B75 is hinged to the other end of the connecting rod A74, and the other end of the connecting rod B75 is hinged to the bottom of the movable plate 72.

[0030] The height of the mounting plate 73 matches the height of the protective glass 513, and the mounting plate 73 is located at the rear end of the protective glass 513.

[0031] When the above equipment is used, when the cabinet door 4 is rotated outward, the mounting rod 511 rotates synchronously with the cabinet door 4, causing the connecting rod A74 to swing around the center of the mounting rod 511. The connecting rod A74 pulls the moving plate 72 along the fixed rod B71 to slide forward through the connecting rod B75, so that the assembly plate 73 moves forward. This allows the electronic components mounted on the front side of the assembly plate 73 to move forward, so that maintenance personnel can perform inspection, replacement or maintenance operations on faulty components. With the assembly plate 73 moved forward, maintenance personnel do not need to extend their bodies too far into the housing 1, providing more operating space for the use of tools and further improving the efficiency and safety of maintenance operations.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
