DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0022] See also Figures 1 to 4 A cable tray for drainage and moisture prevention, comprising an inner bridge 1 and an outer bridge 2, the inner bridge 1 and the outer bridge 2 being arranged at intervals and rotatably connected, the inner bridge 1 and the outer bridge 2 being fixedly connected with a hose 3 for waterproofing, the inner bridge 1 and the outer bridge 2 being rotatably connected by a limiting mechanism 6 so that the inner bridge 1 and the outer bridge 2 can be bent according to the usage scenario, the inner bridge 1 and the outer bridge 2 are respectively provided with a bottom plate 9 for placing cables and a support rod 8, and the support rod 8 and the bottom plate 9 are both provided with a cable clamp 7 for fixing the cables;

[0023] The limiting mechanism 6 includes a swivel seat 61 fixed on the outer bridge frame 2 and a round cover 62 detachably mounted on the swivel seat 61. The interior of the swivel seat 61 is fixedly connected to a base 65, the interior of the base 65 is movably connected to a card wheel 64, and the interior of the base 65 is rotatably connected to two blocks 66 for limiting the rotation of the card wheel 64. A limiting component is provided at the rotation connection between the base 65 and the block 66. One end of the card wheel 64 passes through the swivel seat 61 and the base 65 is fixedly connected to a rotating shaft 63, and the other end of the rotating shaft 63 is fixedly connected to the inner bridge frame 1. The disassembly connection method of the swivel seat 61 and the round cover 62 can be replaced by a threaded and threaded groove meshing connection, so that the device can be reset by toggling the blocks 66 on both sides of the card wheel 64. The base 65 and the block 66 are The limiting component between them can be specifically a torsion spring. First, the required bending angle of the inner bridge frame 1 and the outer bridge frame 2 is determined according to the specific usage scenario and needs. Since the inner bridge frame 1 and the outer bridge frame 2 are rotatably connected through the limiting mechanism 6, the inner bridge frame 1 or the outer bridge frame 2 can be directly rotated to adjust the angle. During the rotation process, the card wheel 64 will rotate accordingly, and the rotating shaft 63 will drive the inner bridge frame 1 to rotate relative to the outer bridge frame 2, thereby realizing the change of the bending angle. When it is rotated to the expected angle, the card block 66 will limit the rotation of the card wheel 64 under the action of the limiting component at the rotation connection between the base 65 and the card block 66, thereby fixing the relative position of the inner bridge frame 1 and the outer bridge frame 2, and ensuring the stability of the cable tray during use. Example

[0024] See also Figures 1 to 4 , this embodiment provides a technical solution based on the first embodiment: both ends of the inner bridge 1 and the outer bridge 2 are provided with a circular groove 4 and a circular hole 5 fixedly connected to the limit mechanism 6, and the bottom of the bottom plate 9 is provided with a heat dissipation hole 10 for heat dissipation, the cable clamp 7 includes a cable seat 71 fixedly connected to the bottom plate 9 and the support rod 8, and the cable seat 71 is movably connected to a threaded U-tube 72 for clamping the cable, and both ends of the threaded U-tube 72 are also provided with threads so that the threaded U-tube 72 passes through the support rod 8 and the bottom plate 9 and fixes the cable through a nut 73. Multiple cable clamps 7 can be set on the support rod 8 and the bottom plate 9 to protect and fix multiple cables at the same time. The cable is placed on the bottom plate 9 or at a suitable position between the support rods 8, and then use the cable clamp 7 to fix the cable. The specific operation is to clamp the cable through the threaded U tube 72 of the cable clamp 7 and tighten it with the nut 73, so as to ensure that the cable can be stably placed in the bridge. At the same time, the heat dissipation holes 10 opened at the bottom of the base plate 9 can effectively promote the heat dissipation of the cable, reduce the risk of damage to the cable due to overheating, and extend the service life of the cable. The hose 3 fixedly connected on the inner bridge 1 and the outer bridge 2 has good waterproof performance, which can effectively prevent moisture from entering the inside of the bridge, provide reliable moisture-proof protection for the cable, and avoid the cable from affecting its normal work due to moisture. The inner bridge 1 and the outer bridge 2 are arranged at intervals and are rotatably connected.

[0025] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0026] Working principle: When working, first determine the required bending angle of the inner bridge frame 1 and the outer bridge frame 2 according to the specific usage scenario and needs. Since the inner bridge frame 1 and the outer bridge frame 2 are rotatably connected by the limit mechanism 6, the inner bridge frame 1 or the outer bridge frame 2 can be directly rotated to adjust the angle. In the process of rotating the inner bridge frame 1 and the outer bridge frame 2, the rotating shaft 63 will drive the clamping wheel 64 to rotate accordingly. Since the rotating seat 61 is fixedly connected to the outer bridge frame 2, and the rotating shaft 63 is fixedly connected to the inner bridge frame 1, the clamping wheel 64 on the base 65 will be restricted from rotating by the clamping block 66, thereby completing the bending. After bending, the fixing is realized, thereby realizing the change of the bending angle. When it is rotated to the expected angle, the clamping block 66 will limit the rotation of the clamping wheel 64 under the action of the limit component at the rotation connection between the base 65 and the clamping block 66, thereby fixing the relative position of the inner bridge frame 1 and the outer bridge frame 2, ensuring the stability of the cable bridge during use. When laying the cable, place the cable on the base plate 9 or in a suitable position between the support rods 8, and then use the cable clamp 7 to fix the cable. The specific operation is to clamp the cable through the threaded U tube 72 of the cable clamp 7 and tighten it with the nut 73 , thereby ensuring that the cable can be stably placed in the bridge. At the same time, the heat dissipation holes 10 opened at the bottom of the bottom plate 9 can effectively promote the heat dissipation of the cable, reduce the risk of damage to the cable due to overheating, and extend the service life of the cable. The hose 3 fixedly connected to the inner bridge 1 and the outer bridge 2 has good waterproof performance, which can effectively prevent moisture from entering the interior of the bridge, providing reliable moisture-proof protection for the cable, and avoiding the cable from being affected by moisture and affecting its normal operation. The design of the inner bridge 1 and the outer bridge 2 being arranged at intervals and rotatably connected, as well as the ingenious setting of the limiting mechanism 6, makes the cable bridge able It is flexible enough to adapt to various different spatial shapes and sizes. It can not only facilitate the smooth passage of cables through various complex spatial environments, but also successfully bypass obstacles such as equipment and pipelines, fully meeting the diverse needs of practical applications. When the bridge needs to be reset, the blocks 66 on both sides of the card wheel 64 are moved to release the restriction on the card wheel 64, and then the inner bridge 1 and the outer bridge 2 are rotated to the initial position, and finally the block 66 is released. The block 66 will automatically return to its original position under the action of the limit assembly, and the rotation of the card wheel 64 is restricted again, thereby completing the reset operation.
