Description

Technical Field

[0001] The invention relates to the technical field of wiring bridges, and in particular to a wiring bridge structure used for intelligent building decoration. Background Art

[0002] Intelligent buildings are buildings that integrate advanced technologies in various aspects such as construction, communications, computer networks and monitoring into an optimized whole. Therefore, a large number of cables of various types need to be distributed in the building. These cables are densely distributed in every corner of the building. There are high-voltage cables for transmitting electricity, as well as low-voltage cables for building broadband networks. The cables need to be classified, arranged, and layered and managed in an orderly manner.

[0003] During renovation, it is necessary to plan the cables and separate and limit the cables in different directions so that the wires can be arranged along straight or curved lines. The cable layout is standardized and reasonable. When wiring or routing, the cables usually need to be fixed on the bridge, which causes the cable ends to be pulled during wiring or routing, inevitably causing fatigue damage to the cable surface and reducing the service life of the cable, especially when turning corners or changing directions. Therefore, the applicability of cables in the current complex environment still needs to be further optimized. Summary of the invention

[0004] The purpose of the present invention is to provide a wiring bridge structure for intelligent building decoration, which can avoid fatigue damage to the wire ends and skin of the cables due to being pulled, thereby improving the service life of the cables.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A wiring bridge structure for intelligent building decoration, comprising a bridge body, the upper top wall and the lower bottom wall of the bridge body are both provided with a first slide groove, the interiors of the upper and lower first slide grooves are simultaneously slidably connected with vertical plates, and the opposite sides of the bridge body and the vertical plate are provided with a clamping limit mechanism;

[0006] The outer side surface of the vertical plate is fixedly connected to a limit slot block, the interior of the limit slot block is slidably connected to a driving plate, and a pressure sensor is fixedly connected between the limit slot block and the driving plate;

[0007] An electric telescopic rod is fixedly connected to the upper surface of the bridge body, a first rectangular hole is opened on the top of the bridge body, a connecting plate is rotatably connected to the side wall of the first rectangular hole, and the extended end of the electric telescopic rod is movably connected to the outer end of the driving plate through the connecting plate;

[0008] A control device electrically connected to the electric telescopic rod and the pressure sensor is also arranged inside the bridge frame body.

[0009] By adopting the above technical solution, through the coordination between the bridge body, the electric telescopic rod, the connecting plate, the first rectangular hole, the control device, the first slide groove, the vertical plate, the limit slot block, the driving plate and the pressure sensor, when in use, the cable is passed through the clamping limit mechanism, when the cable is subjected to force, the cable drives the limit slot block to move horizontally relative to the driving plate, the pressure sensor is compressed by the limit slot block and the driving plate, the pressure of the cable can be sensed through the pressure sensor, the pressure sensor transmits the electrical signal to the input relay inside the control device, the input relay transmits the signal to the PLC control module, and the PLC control module After block recognition, the comparator compares the input signal with the set threshold, and then transmits the signal to the output relay. The output relay controls the extension and retraction of the electric telescopic rod. The electric telescopic rod drives the driving plate to move horizontally through the connecting plate, and the driving plate drives the vertical plate to move horizontally in the first slide groove, so as to realize automatic relaxation and clamping of the cable, and realize free adjustment of the pressure of the cable end. When routing and wiring, the cable end and skin are prevented from being pulled and fatigue damaged, thereby increasing the service life of the cable. When the cable end is pulled, the pressure can be freely adjusted to protect the cable end and skin.

[0020] The present invention is further configured as follows: the interior of the T-shaped tube is slidably connected to a T-shaped block, and the arc-shaped block is fixedly connected to the outer surface of the T-shaped block.

[0021] By adopting the above technical solution, when the cable is thinner, a T-shaped block is added between the arc block and the T-shaped tube, so that the thinner cable can fit into the arc block when clamped together with a thicker cable.
