The utility model provides an adjustable antenna mounting rack, and relates to the field of 5G equipment tools. The adjustable antenna mounting rack comprises two plate bodies used for mounting an antenna and a mounting structure, the mounting structure comprises a first adjusting assembly and a second adjusting assembly, the first adjusting assembly comprises a barrel shell, the two plate bodies are symmetrically arranged on the two sides of the barrel shell, and the top ends of the plate bodies are connected with the outer wall of the top end of the barrel shell through hinge seats. The first adjusting assembly and the second adjusting assembly are arranged in a matched mode, the rotating direction of the threaded rod is controlled through the first servo motor, the movable base is driven to move, the inclined rod can rotate along the hinge point of the inclined rod, then the plate body is driven to rotate along the hinge point of the plate body and the barrel shell, and the inclination angle of the plate body is adjusted; through cooperation of the arrangement of the second adjusting assembly, the first adjusting assembly and the plate body can be driven to rotate, so that the mounting angle of the antenna can be changed by adjusting the angle of the plate body, the signal receiving and releasing effect can be improved, and the practicability of the mounting rack is improved.

This utility model discloses a cable reel for communication maintenance, including a cable reel assembly with a rotatable shaft. The assembly also includes a power source to drive the shaft to rotate for cable reeling and unloading; a support symmetrically distributed on the assembly; a linear motion component mounted on the support; a first guide component that drives the linear motion component to reciprocate along the length of the shaft, guiding the cable to spirally wind onto the shaft during reeling; and a tension cylinder located at the moving end of the linear motion component. This utility model enables the cable to be wound evenly and neatly, preventing overlap and excessive friction during winding. Furthermore, the tension cylinder ensures effective tension during both reeling and unloading, further improving the efficiency of the process.

This utility model relates to the field of communication cable technology and discloses a communication cable winding and unwinding device, including a mounting base, a controller, a moving component, a rotating component, a winding drum, and a limiting component. The controller is connected to the side of the mounting base, the moving component is disposed inside the mounting base, the rotating component is disposed inside the mounting base, the winding drum is disposed on the surface of the rotating component, and the limiting component is disposed on the top of the mounting base. The moving component consists of a threaded rod, a guide rod, a first motor, a threaded sleeve, and a conductor seat. This communication cable winding and unwinding device uses the controller to cause the first motor to periodically rotate forward and backward, which in turn causes the threaded sleeve to drive the conductor seat to move horizontally back and forth. The controller also causes the second motor to rotate, which in turn drives the winding drum to rotate and wind the communication cable. During the winding process, the lower pressure plate remains in contact with the surface of the communication cable, resulting in a tighter winding and better cable winding and unwinding performance.
