Technical Field

The utility model relates to the technical field of weak current boxes, in particular to a weak current box which is easy to fix.

Background Art

As the name suggests, the weak-current box is a centralized box for weaker voltage lines, which is generally used in modern home decoration. Network cables, telephone lines, computer monitors, USB cables, TV antennas, etc. can be placed in it. In 2002, the country began to implement the policy of separating strong and weak electricity, and thus the weak-current box came into being. It is mainly used for unified management and distribution of household weak-current signals, including network, telephone, television, security and other weak-current wiring. It mainly avoids weak-current signals from being interfered with by strong electricity and improves the quality of family life. The weak-current box is directly embedded in the wall and fixed with cement or concrete.

There is an intelligent weak-current box with Chinese patent publication number CN213753659U, which includes a weak-current box body and a motor box fixedly installed on the inner wall of the weak-current box body, a micro forward and reverse motor is fixedly arranged in the motor box, and the output of the micro forward and reverse motor in the motor box is transmission-connected with a threaded rod, and the threaded rod is rotatably passed through the threaded hole. The utility model is provided with a mounting plate for mounting components inside the weak-current box, which is fixedly sleeved on a movable block, and a threaded rod is rotatably passed through the through hole on the movable block, and one end of the threaded rod is transmission-connected with the output end of the micro forward and reverse motor in the motor box; however, most of the existing weak-current boxes are installed by embedding them inside the wall and fixing them by cement. The existing weak-current box installation method not only needs to wait for the cement to be completely solidified before fixing it, but also has low efficiency and cumbersome operation. At the same time, if the weak-current cable is damaged in the future, maintenance is difficult.

Therefore, we propose a low-voltage box that is easy to fix in order to solve the above-mentioned problems.
