Description

Technical Field

[0001] The utility model relates to the technical field of weak current wiring racks, in particular to a weak current wiring rack device between buildings. Background Art

[0002] The inter-building weak-current wiring rack refers to the equipment used for wiring and connecting weak-current cables in various parts of the building. It is usually used for the construction and wiring of weak-current systems such as telecommunications, networks, security, audio and video. It plays an important role in the wiring of weak-current systems in buildings. It is not only related to the normal operation and service life extension of the weak-current system, but also has important significance for the safety management and information construction of the building.

[0003] After searching, it was found that the technical solution provided by the utility model with application number CN202320985430.8 is fixed to the pole of the cable rack by rivets through two sets of fixed plates. After the rotating block is inserted into the circular hole of the snap plate, the rotating block is rotated to separate the insulating ball from the inner side of the snap plate so that the snap plate and the rotating block are in contact to realize circuit connection. The through hole at the end of the rotating block is connected to the sliding connecting rod. After the end is connected to the adjustment slot in the fixed plate, angle conversion adjustment and multi-line connection can be realized. However, this connection method has certain disadvantages. Since no limiting structure is set in the adjustment slot, the fixed plate and the sliding connecting rod will shake once they are subjected to slight external force, resulting in an unstable connection. When the connection shakes, the cable will bend, affecting the circuit transmission efficiency of the cable and even causing safety hazards. Utility Model Content
