Description

Technical Field

[0001] The utility model relates to the field of communication chassis, in particular to a locking mechanism for fixing a communication chassis. Background Art

[0002] A communication chassis refers to a chassis cabinet used for communications. The components inside the chassis are connected through lines, and wiring is required inside the communication chassis. After the cables are laid out, they need to be locked and fixed by a locking mechanism to prevent them from moving.

[0003] According to a Chinese patent with publication number CN219145902U, a locking mechanism for fixing a communication chassis is disclosed. When the utility model is actually used, it is convenient to adjust the height of the line so that the line is in a vertical state and the lines can be arranged together in an orderly manner. It is not only convenient to install, but also when a component inside the communication chassis fails, the faulty line can be found in time for easy maintenance.

[0004] In response to the above-disclosed patent content, an upper arc pad and a lower arc pad are provided so that the upper arc pad moves downward to compress and limit the cable. Since the upper arc pad and the lower arc pad form a cylindrical shape, when it is necessary to lock and fix a cable with a diameter smaller than the diameter of the upper arc pad, the cable can only be initially positioned by relying on the lower arc pad. Since the cable diameter is small, the upper arc pad cannot contact the top of the cable when moving downward, which makes it difficult to lock and fix the cable. As a result, the cable may move when pulled externally, thereby reducing the applicability of the locking structure and reducing the locking and fixing efficiency of the locking structure for the cable. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a locking mechanism for fixing a communication chassis, so as to solve the technical problem that the locking mechanism has a small application range, resulting in difficulty in locking and fixing cables with smaller diameters.

[0011] By adopting the above technical solution, when the threaded rod rotates, it will drive the movable seat to move, and the sliding rod can guide the sliding seat so that the sliding seat can stably slide inside the sliding groove.

[0012] Furthermore, a movable plate is connected between the sliding seat and the movable seat, and the movable seat is threadedly connected to the threaded rod.

[0013] By adopting the above technical solution, when the movable seat moves downward, it will drive the movable plate to move, and the movable plate will then drive the sliding seat to move, so as to improve the stability of the movable plate when moving.

[0014] Furthermore, a plurality of sleeves are provided at the bottom of the movable plate, a spring is provided inside the sleeve, and the bottom end of the spring is connected to a movable rod extending to the outside of the sleeve.

[0016] Furthermore, a pressure plate is fixed to the bottom end of the movable rod, and a rubber pad is provided at the bottom of the pressure plate.

[0017] By adopting the above technical solution, when the movable rod moves, it will drive the pressure plate to move downward, so that the pressure plate can press the top of the cable to limit the top of the cable.

[0018] Furthermore, an air guide channel is provided at the lower part of the bottom plate, and an air vent is provided between the air guide channel and the arc groove.

[0019] By adopting the above technical solution, air can enter the vent hole through the air guide channel, and then enter the interior of the arc groove, so that the air in the arc groove can flow freely.
