Description

TECHNICAL FIELD

[0001] The utility model relates to cable distribution box technical field, especially a kind of cable distribution box sealing structure and cable distribution box. BACKGROUND

[0002] With the development of the process of cable distribution network, when the independent load with small capacity is distributed relatively concentrated, cable branch box can be used to connect cable multi-branching. The main function of cable branch box is to distribute or relay cable. The existing cable terminal box is usually wired at the bottom, so an opening is formed at the bottom. A bottom plate is arranged at the opening to block the opening. Mounting holes are formed on the plate to extend the cable into the box. When in use, the bottom plate is installed at the bottom of the cable terminal box. Since the bottom plate is a whole piece and the distance between the side of the bottom plate and the side wall of the cable terminal box is small, the rotation or movement of the bottom plate in the box is limited by the space in the box, making it difficult to adjust the relative position of the bottom plate and inconvenient to assemble and disassemble the bottom plate. If the bottom plate is divided into two pieces, the length or width of each bottom plate is reduced. When installing, the two pieces of bottom plate are installed side by side in the cable distribution box. However, since there is a gap between the plates, the sealing performance is reduced. Therefore, a new technical solution is needed to solve this problem. SUMMARY

[0003] The main purpose of the utility model is to provide a kind of cable distribution box sealing structure and cable distribution box, it aims at guaranteeing the premise of sealing, reduce the influence of the rotation or movement of the bottom plate in the box to solve the problem of inconvenient assembly and disassembly of the bottom plate in the prior art.
