Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, specifically a cable branch box. Background Technology

[0002] A cable branch box, also known as a cable junction box, is a junction box that branches a single cable into one or more cables. With the development of cable-based power distribution networks, cable branch boxes can be used to connect multiple branches of cables when independent loads of small capacity are concentrated in one area. Because branch boxes cannot directly operate on each individual cable, they are only used for branching cables. The main function of a cable branch box is to split or transfer cables.

[0003] Existing cable distribution boxes are widely used outdoors. Due to the diverse and complex outdoor environment, timely drainage is necessary during thunderstorms to prevent water from entering the box, corroding the circuits, and causing danger. Currently, flip-top designs are often used to facilitate a clearer view of the internal wiring distribution during maintenance. However, when the door is flipped up for maintenance, it is supported by a telescopic rod. Since the door is made of metal, the weight is applied to the telescopic rod itself. Over time, the support capacity of the telescopic rod decreases, making it easy for the door to fall during maintenance, potentially injuring maintenance personnel. Summary of the Invention

[0004] The purpose of this utility model is to provide a cable distribution box to solve the problem mentioned in the background art. Existing cable distribution boxes are widely used outdoors. Because the outdoor environment is diverse and complex, in the event of thunderstorms, it is necessary to ensure timely water drainage to prevent water from entering the box, corroding the circuits, and causing danger. Currently, a flip-top design is often used to facilitate a clearer view of the internal wiring distribution during maintenance. However, when the door is flipped up during maintenance, it is supported by a telescopic rod. Since the door is made of metal, the weight is applied to the telescopic rod itself. Under long-term support, the support capacity of the telescopic rod is reduced, which makes the door easy to fall during maintenance, potentially injuring maintenance personnel.

[0006] Preferably, the limiting assembly includes a fixed base, a universal joint, and a limiting plate. The fixed base is fixedly connected to the inner wall surface of the door, and the fixed base and the limiting plate are connected by a universal joint.

[0007] Preferably, the limiting plate has multiple limiting holes on its surface, and the limiting plate is sleeved onto the limiting post through the limiting holes.

[0008] Preferably, the two ends of the housing are provided with locking positions below the maintenance openings, and a locking block is fixedly connected to the center of the surface of the locking position, and a locking hole is provided on the surface of the locking block.

[0009] Preferably, a locking plate is fixedly connected to the bottom surface of the door body at a position opposite to the locking position, and an avoidance opening is provided on the surface of the locking plate at a position opposite to the locking block, and a locking block is movably connected in the avoidance opening.

[0010] Preferably, a downwardly curved connecting plate is fixedly connected to the top surface of the locking plate, and the connecting plate and the locking plate adopt an integral structural design.

[0011] Preferably, a storage clip for storing the limiting plate is fixedly connected to the inner wall of the door.

[0012] Beneficial effects

[0025] like Figure 1-4 This is a schematic diagram of a preferred embodiment of the present invention for a cable branch box. In this embodiment, the cable branch box includes a box body 1, with maintenance openings 3 on both sides of the box body 1. A door body 2 is movably connected to the maintenance openings 3. Telescopic rods 4 are symmetrically fixedly connected to the inner wall of the box body 1 at the maintenance openings 3, and the output end of the telescopic rods 4 is fixedly connected to the inner wall of the door body 2. A limiting post 5 is fixedly connected to the inner wall of the box body 1 on one side of the telescopic rod 4. A limiting component 8 is movably connected to the inner wall of the door body 2, and the limiting component 8 is movably connected to the surface of the limiting post 5. In combination with the structural design of the present invention, by setting the limiting component 8 and the limiting post 5, the door body 2 can play an auxiliary support role when opened during maintenance through the action of the limiting component 8 and the limiting post 5, effectively avoiding the concentration of gravity on the telescopic rods 4, and further ensuring the safety of maintenance personnel.

[0026] In this embodiment, the limiting component 8 includes a fixed base 81, a universal joint 82, and a limiting plate 83. The fixed base 81 is fixedly connected to the inner wall surface of the door body 2. The fixed base 81 and the limiting plate 83 are connected through the universal joint 82. The universal joint 82 enables the limiting plate 83 to rotate at multiple angles. Multiple limiting holes 84 are provided on the surface of the limiting plate 83. The limiting plate 83 is sleeved on the limiting post 5 through the limiting holes 84. With this structural design, when the maintenance personnel flip the door body 2 upward, the telescopic rod 4 extends, and the maintenance personnel can take the limiting plate 83 out of the storage clip 6 and sleeve the limiting plate 83 on the surface of the limiting post 5 through the limiting holes 84, which plays an auxiliary support role and effectively avoids the concentration of gravity on the telescopic rod 4, further ensuring the safety of maintenance personnel.

[0027] In this embodiment, locking positions 11 are provided at both ends of the housing 1 below the maintenance opening 3. A locking block 12 is fixedly connected to the middle of the surface of the locking position 11, and a locking hole 13 is provided on the surface of the locking block 12. A locking plate 7 is fixedly connected to the bottom surface of the door 2 at the opposite position of the locking position 11. An avoidance opening 72 is provided on the surface of the locking plate 7 at the opposite position of the locking block 12, and the locking block 12 is movably connected in the avoidance opening 72. In actual use, the locking plate 7 is movably connected in the locking position 11 as the door 2 flips up and closes down. At the same time, the avoidance opening 72 mainly cooperates with the locking block 12. When the door 2 closes down, the locking plate 7 is located in the locking position 11, and the locking block 12 is located in the avoidance opening 72. At the same time, the front end of the locking block 12 passes through the avoidance opening 72 so that the locking hole 13 is located outside the locking plate 7. The locking of the door 2 is achieved by the lock passing through the locking hole 13.

[0028] In this embodiment, a downwardly curved connecting plate 71 is fixedly connected to the top surface of the locking plate 7. The connecting plate 71 and the locking plate 7 adopt an integrated structural design. With this structural design, maintenance personnel can open the door 2 by lifting the connecting plate 71 when performing maintenance work, which facilitates the maintenance work of maintenance personnel.

[0029] In this embodiment, a storage clip 6 for storing the limiting plate 83 is fixedly connected to the inner wall of the door 2. This structural design prevents the limiting plate 83 from shaking inside the box 1 when the door 2 is closed, thereby affecting the use of the components inside the box 1.

[0030] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
