[0020] Please refer to the attached Figure 1-Figure 3 A partially detachable cable bridge comprises a bridge body 1, a plurality of rectangular grooves are provided on the upper surface of the bridge body 1, the bridge body 1 is provided with a first vertical groove 2 on both the front and rear sides of the rectangular groove, a slider 12 with a U-shaped cross section is slidably connected in the first vertical groove 2, the slider 12 faces the mounting ring 11, the ring 11 is installed on one side of the slider 12 in the bridge body, a round rod 8 is inserted in the ring 11, conical grooves 9 are provided on the annular surfaces at both ends of the round rod 8, and the ends with larger cross sections of the two conical grooves 9 are arranged oppositely, a U-shaped frame 4 is inserted in the rectangular groove, a second vertical groove 7 is provided on both the front and rear sides of both ends of the U-shaped frame 4, and the bottom position of the second vertical groove 7 is slightly lower than the bottom position of the first vertical groove 2.

[0021] A moving plate 13 with an L-shaped cross-section is slidably connected in the second vertical groove 7, and a rotating groove is provided on the upper surface of the moving plate 13. A rotating block is rotatably connected in the rotating groove. A lifting plate 15 is installed at one end of the rotating block outside the rotating groove. An arc groove 14 is provided on the side of the lifting plate 15 facing the round rod 8. The arc groove 14 contacts the lower side of the annular surface of the conical groove 9. A screw rod 3 is installed on the upper surface of the moving plate 13, and circular holes are provided on the front and rear sides of the upper surface of the frame body. The end of the screw rod 3 away from the lifting plate 15 is inserted into the circular hole and threadedly connected to the nut 5, and the nut 5 is arranged on the upper surface of the circular hole.

[0022] When the round rod 8 is inserted into the circular ring 11 and the conical groove 9 on the round rod 8 contacts the arc groove 14 , the lifting plate 15 can limit the position of the round rod 8 , thereby preventing the round rod 8 from being taken out of the circular ring 11 .

[0023] In order to facilitate observation of the cables in the bridge body and to dissipate heat from the cables, a plurality of ventilation grooves 6 are provided on the upper surfaces of the bridge body 1 and the U-shaped frame 4 .

[0024] In order to allow the cables to pass through the round rod 8 and avoid intertwining and entanglement, a plurality of separation grooves 10 are provided on the annular surface of the round rod 8 .

[0025] The specific operation process of the present invention is as follows: the initial positions of the ring 11 and the slider 12 are set at the bottom of the first vertical groove 2, and then the round rod 8 is inserted into the ring 11, and then the cables are moved in sequence from the dividing grooves 10 on the round rod 8 using multiple rectangular grooves. After the cable is laid, the U-shaped frame 4 is inserted into the rectangular groove. Since the bottom position of the second vertical groove 7 is slightly lower than the bottom position of the first vertical groove 2, the lifting plate 15 is rotated after the U-shaped frame 4 is inserted into the rectangular groove so that the lifting plate 15 is located below the round rod 8, and then the screw 3 is pulled to raise the position of the movable plate 13, thereby driving the position of the lifting plate 15 to rise, so that the arc groove 14 contacts with the conical groove 9 on the round rod 8, and finally the practical nut 5 is used to limit the height of the movable plate 13 in the U-shaped frame 4.

[0026] When the cable is pulled, the round rod 8 rotates with the cable, thereby reducing the friction of the cable and making it easier for the cable to pass. When the cable passes through the round rod 8, the pressure of the cable can make the conical groove 9 and the arc groove 14 fit tightly, making it impossible for the round rod 8 to be removed from the ring 11.

[0027] Since the lifting plate 15 is fixed in position, the round rod 8 cannot be separated from the arc groove 14 under the pressure of the cable, thereby limiting the front and rear positions of the U-shaped frame 4 in the bridge body 1. Since the cable presses the round rod 8, the upward movement of the round rod 8 is restricted. At this time, the upward movement of the U-shaped frame 4 can be restricted, thereby fixing the U-shaped frame 4 in the bridge body 1.

[0028] Then, according to the requirements of the use environment, the movable plate 13 is raised in the second vertical groove 7, and the connecting rod and the ring 11 are also raised. When the required position is reached, the height of the screw rod 3 is limited by the nut 5 to fix the position of the lifting plate 15 in the bridge frame body 1.

[0029] When the U-shaped frame 4 needs to be opened, first support the slider 12 to keep the position of the slider 12 unchanged, loosen the nut 5 to lower the position of the screw rod 3, and then rotate the lifting plate 15 to separate the lifting plate 15 from the round rod 8. At this time, the U-shaped frame 4 can be taken out from the bridge body 1.

[0030] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
