The bottom trough 20 is detachably connected to the top plate 10, and the bottom trough 20 is movably pressed against the plug-in plate 40. The wire threading hole is formed by using the door-shaped plate 30 and the plug-in plate 40 to facilitate cable installation and maintenance. The bottom trough 20 is pressed against the plug-in plate 40 to further reduce the wire threading hole and improve the sealing performance. The size of the wire threading hole can be changed by selecting plug-in plates 40 of different specifications, which has good versatility.

[0031] See also Figures 1-4 A hanger 50 is provided on the top plate 10, and the hanger 50 corresponds to the position of the door-shaped plate 30. The hanger 50 is used to hang the entire bridge on the ceiling. The position of the door-shaped plate 30 is the main connection position with the cable. Therefore, the gravity of the cable can be transferred to the hanger 50 as directly as possible.

[0032] See also Figures 1-4 , a cushion 60 is provided on both the door plate 30 and the plug plate 40. The cushion 60 is made of fireproof material and is used to improve the sealing performance between the door plate 30 and the plug plate 40 and the cable. It should be noted that the cushion 60 can be freely cut according to the size of the threading hole.

[0033] See also Figures 1-4 , a pre-cut slit 70 is provided on the plugboard 40. According to the actual number and diameter of the cables, the plugboard 40 can be broken off to change the size of the threading hole between the plugboard 40 and the door-shaped plate 30 to adapt to the actual cables and improve the sealing performance. In another embodiment, multiple plugboards 40 are provided, and the size of the threading hole is adjusted by the number of plugboards 40. It should be noted that both of the above embodiments require that the plugboard 40 and the door-shaped plate 30 have a certain friction damping so that the plugboard 40 will not fall off the door-shaped plate 30 before the bottom groove 20 is installed.

[0034] See also Figures 1-4 A screw rod 80 is fixedly connected to the top plate 10, and a cross bar 90 is provided on the screw rod 80. A nut 100 is screwed on the screw rod 80 and tightened against the cross bar 90. Before inserting the plugboard 40, the cables are first restrained in the door-shaped plate 30 by adjusting the cross bar 90. This makes the bottom of the wire harness flat and easy to fit with the upper end of the plugboard 40, and then the plugboard 40 is inserted.

[0035] See also Figures 1-4 , the screw 80 passes through the bottom groove 20, and another nut 100 is pressed against the bottom groove 20.

During maintenance, you only need to unscrew the two nuts 100 to open the bottom groove 20. In this embodiment, adjacent cover plates are connected by connecting plates and screws, and adjacent bottom grooves 20 are sealed with fireproof tape.

[0036] See also Figures 1-4A smoke sensor 120 and an electromagnetic nozzle 130 are provided on the top plate 10. The smoke sensor 120 is used to sense smoke, and the external dry powder fire extinguishing system extinguishes the fire inside the bridge by connecting to the electromagnetic nozzle 130, which is controlled by a solenoid valve.

[0037] The working principle of this fireproof trough bridge that is easy to disassemble and assemble is as follows: the hanger 50 is used to hang the entire bridge on the ceiling, first pass the cable through, then pass the crossbar 90 on the screw 80, use the nut 100 to constrain the wire harness to the door-shaped plate 30 and make the bottom surface flat, then insert the plug plate 40 into the door-shaped plate 30, use the soft pad 60 to ensure the sealing, and finally insert the bottom trough 20 upward into the screw 80, and insert the positioning pin 110 into the positioning hole to ensure that the bottom trough 20 and the top plate 10 fit firmly. Then tighten the nuts 100. During maintenance, you only need to unscrew the two nuts 100 to open the bottom groove 20, and then remove the cross bar 90 to completely expose the cables. It is easy to disassemble and easy to maintain. In summary, the door-shaped plate 30 and the plug-in plate 40 are used to form a threading hole, which is convenient for cable installation and maintenance. The bottom groove 20 is used to press the plug-in plate 40 to further reduce the threading hole and improve the sealing. The size of the threading hole can be changed by selecting plug-in plates 40 of different specifications, which has good versatility.
