DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] Example 1, with reference to Figure 1 and Figure 3-6 , a retractable aluminum alloy cable tray, comprising a U-shaped main board 1 and a cross fixing seat 2; In this embodiment, two U-shaped extended sub-plates 6 are connected to the U-shaped main plate 1 via a telescopic structure. The telescopic structure includes a fixed cover 3 fixedly connected to the side wall of the U-shaped main plate 1, a bidirectional screw 4 rotatably mounted within the fixed cover 3, and two sliding blocks 5 symmetrically screwed to the two opposite threaded ends of the bidirectional screw 4. Among them, the U-shaped main board 1 and the two U-shaped extended sub-boards 6 are all made of aluminum alloy, the two sliding blocks 5 are respectively fixedly connected to the two U-shaped extended sub-boards 6, a slide 10 is opened on one side of the U-shaped main board 1, the outer walls of the two sliding blocks 5 are slidably connected to the inner wall of the slide 10, a telescopic channel 11 is opened in the U-shaped main board 1, and the two U-shaped extended sub-boards 6 are slidably connected to the telescopic channel 11, so that the two sliding blocks 5 can drive the two U-shaped extended sub-boards 6 to slide smoothly in the telescopic channel 11; Among them, a threaded locking column 7 is coaxially welded to the outer wall of one end of the bidirectional screw 4, a rotating cap 8 is fixedly connected to the outer wall of one end of the threaded locking column 7, and a locking nut 9 is threadedly connected to the threaded locking column 7; The usage of this embodiment is as follows: first, the cross fixing seat 2 is fixed to the ceiling by bolt fasteners, and then the threaded locking column 7 is controlled to rotate by the turning cap 8, and then the threaded locking column 7 will drive the bidirectional screw 4 to rotate. Under the limit of the slide 10, the two sliding blocks 5 threadedly connected to the bidirectional screw 4 will move away from each other, and then the two U-shaped extended sub-plates 6 will slide in the telescopic channel 11 and extend outward, so that the entire cable tray can be telescopically adjusted, thereby facilitating the flexible adjustment of the length of the entire cable tray to adapt to the use requirements of cables of different lengths.
[0021] Example 2, reference Figure 1-2 and Figure 7 This embodiment is optimized based on the first embodiment. Specifically, an angle adjustment structure is provided above the U-shaped mainboard 1. The angle adjustment structure includes a connecting plate 16 fixedly connected to the top outer wall of the U-shaped mainboard 1, a hollow box 17 fixedly connected to the bottom outer wall of the cross fixing seat 2, an angle self-locking device, and a guide assembly. The angle self-locking device includes a rotating shaft 18 rotatably mounted in the hollow box 17, a ratchet 19 fixedly mounted on the top of the rotating shaft 18, a pawl 20 rotatably connected to the top inner wall of the hollow box 17 via a pin, a spring seat fixedly connected to the top inner wall of the hollow box 17, and a connecting spring 21 fixedly connected between the spring seat and the pawl 20. The ratchet 19 and the pawl 20 are engaged with each other. The bottom end of the rotating shaft 18 is coaxially welded to the top outer wall of the adapter plate 16. The guide assembly includes two reinforcing ribs 22 symmetrically welded to the outer circumferential wall of the adapter plate 16, two rolling members 23 symmetrically fixed to the top of the two reinforcing ribs 22, and an annular guide rail 24 fixedly connected to the outer wall of the cross fixing seat 2. The two rolling members 23 form a rolling fit with the annular guide rail 24. The guiding effect of the guide assembly facilitates the stability of the rotation of the adapter plate 16. The usage of this embodiment is: by pushing the U-shaped main board 1 to rotate the connecting plate 16, the rotation of the connecting plate 16 will cause the ratchet 19 on the rotating shaft 18 to rotate. Under the engagement relationship of the pawl 20, it can be self-locked during the rotation adjustment process, and when the connecting plate 16 rotates, the two rolling members 23 will roll along the annular guide rail 24 to ensure the stability of the rotation adjustment. This makes it easy to flexibly adjust the installation angle of the entire cable tray during installation, thereby meeting the installation and deployment requirements of cables in different orientations.
[0022] Example 3, reference Figure 4-6 and Figure 8This embodiment is optimized based on the first embodiment. Specifically, a shock-absorbing support structure is provided in the U-shaped mainboard 1. The shock-absorbing support structure includes a shock-absorbing seat 12 slidably arranged in the U-shaped mainboard 1, four cable supporting main seats 13 fixed to the top outer wall of the shock-absorbing seat 12 and distributed at equal distances, and two bidirectional shock-absorbing components 14 symmetrically arranged at the bottom of the shock-absorbing seat 12. Among them, the top outer walls of the two U-shaped extended sub-plates 6 are fixed with four equally distributed cable support sub-seats 15, and the tops of all the cable support sub-seats 15 and the cable support main seat 13 are provided with C-shaped grooves; The bidirectional shock absorbing assembly 14 includes a connecting frame 25 fixedly connected to the bottom outer wall of the shock absorbing seat 12, a guide rail frame 26 fixedly connected to the bottom outer wall of the U-shaped main board 1, two vertical dampers 27 symmetrically installed between the connecting frame 25 and the guide rail frame 26, two shock absorbing vertical springs 28 sequentially sleeved on the two vertical dampers 27, a sliding seat 29 slidably connected to the guide rail frame 26, two linkage oblique rods 30 symmetrically hinged to the tops of the two sliding seats 29, two transverse dampers 31 symmetrically fixed to the top outer wall of the guide rail frame 26, and two shock absorbing transverse springs 32 sequentially fixedly sleeved on the two transverse dampers 31, the top ends of the two linkage oblique rods 30 are both hinged to the bottom of the connecting frame 25, and the opposite ends of the two transverse dampers 31 are respectively fixed to the outer walls of the two sliding seats 29 on the sides away from each other; The usage of this embodiment is as follows: first, the two cable support sub-seats 15 at both ends and the middle cable support main seat 13 are used to support the cables; secondly, when subjected to vibration, the shock-absorbing seat 12 moves downward to enable the two bidirectional shock-absorbing assemblies 14 to work. At this time, the two shock-absorbing vertical springs 28 on the two vertical dampers 27 in the bidirectional shock-absorbing assembly 14 will undergo elastic deformation to reduce the vibration force vertically; finally, the two linked oblique rods 30 move and make the two sliding seats 29 move away from each other. At this time, the two shock-absorbing transverse springs 32 on the two transverse dampers 31 will undergo elastic deformation to reduce the vibration force again in the transverse direction. In this way, the shock absorption performance of the entire aluminum alloy cable tray is improved by the effect of bidirectional shock absorption, thereby ensuring the stability of the connection of the entire aluminum alloy cable tray.
