Technical Field

[0001] This utility model relates to the field of optical fiber distribution box technology, specifically to a box structure for an optical fiber distribution box. Background Technology

[0002] Fiber optic distribution boxes are important equipment in fiber optic communication networks. They have functions such as connecting main optical cables and branch optical cables, distributing fiber optic signals, and protecting optical fibers. They are often wall-mounted or embedded, have a certain level of protection, and are equipped with accessories such as fiber optic splice trays and adapters. They are widely used in residential communities, commercial buildings, and urban communication network construction to realize the distribution and transmission of fiber optic signals and provide fiber optic access services for user terminal equipment.

[0003] When using traditional fiber optic distribution boxes, the cable insertion holes at the bottom of the box are not sealed when the cables are inserted. This leaves a gap between the box and the outside, allowing external debris and moisture to enter the box through the insertion holes and cables, thus affecting the stable operation of the internal electronic components. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a box structure for an optical fiber distribution box, which has the advantages of good sealing effect and convenient use, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a box structure for an optical cable distribution box, comprising a box, a side door rotatably connected to the outer wall of the box, a fixed seat fixedly mounted on the inner wall of the box, a movable plate movably sleeved on the outer wall of the fixed seat, a sealing plug fixedly mounted on the outer wall of the movable plate, a fixed cylinder fixedly mounted on the outer wall of the fixed seat, a drive screw threadedly connected to the inner wall of the fixed cylinder, a cable fixedly mounted on the bottom of the box, a fixed rod fixedly mounted on the outer wall of the side door, a connecting seat fixedly mounted on the outer wall of the box, a rotating frame rotatably connected to the outer wall of the connecting seat, a tension spring installed in the inner cavity of the rotating frame, a movable rod movably sleeved in the inner cavity of the rotating frame, and a locking seat fixedly mounted on the outer wall of the movable rod.

[0006] As a preferred technical solution of this utility model: the outer wall shape of the movable plate matches the outer wall shape of the fixed seat, and the outer wall diameter of the sealing plug matches the outer wall diameter of the connecting cylinder.

[0007] As a preferred technical solution of this utility model: there are two sealing plugs, and the two sealing plugs are respectively installed on both sides of the inner cavity of the box.

[0008] As a preferred technical solution of this utility model: the outer wall shape of the moving rod matches the inner wall shape of the rotating frame, and the outer wall shape of the locking seat matches the outer wall shape of the fixed rod.

[0009] As a preferred technical solution of this utility model: the two ends of the outer wall of the tension spring are respectively connected to the outer wall of the moving rod and the inner wall of the rotating frame, and the tension spring is made of high carbon steel.

[0010] As a preferred technical solution of this utility model: the sealing plug is made of natural rubber, and the bottom of the driving screw is in contact with the top of the moving plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The optical fiber distribution box has a box structure with a fixing seat on the inner wall of the box and a sealing plug on the outer wall of the fixing seat. After the cable passes through the connecting tube, the position of the sealing plug is adjusted so that the sealing plug enters the inner cavity of the connecting tube. The outer and inner walls of the sealing plug contact the inner wall of the connecting tube and the outer wall of the cable, respectively, thereby sealing the connection tube and the cable and ensuring the stable use of the box.

[0012] 2. The optical cable distribution box's structure, through a rotating frame installed on the outer wall of the box, allows the locking seat to be pulled when the side door needs to be fitted to the box. This causes the locking seat to align with the fixing rod, and the moving rod is pulled by the tension spring, thereby moving the locking seat. This results in the side door fitting more tightly to the outer wall of the box, and the tension spring provides better continuous traction and fixation of the side door, achieving a better sealing effect.
