Detailed Description of the Preferred Embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution: a bidirectional seismic support applicable to different cable trays, including: a carrier rod 1, a clamping piece 2, a limiting plate 3, a turning handle 4, a threaded rod 5, a stop block 6, a spring 7, a moving groove 8, a cable tray body 9, a connecting column 10, a sleeve 11, an extension column 12, a shock absorption mechanism 13, a mounting hole 14, a plug rod 15 and a limiting rod 16;

[0029] When using the bidirectional seismic support applicable to different cable trays, as Figure 1 and Figure 5As shown in the figure, first adjust the distance between the two clamping pieces 2 on the carrier rod 1 to facilitate placing cable tray bodies 9 of different sizes. Then fixedly connect the shock-absorbing mechanism 13 above the shock-absorbing mechanism 13. Next, rotate the insertion rod 15 from the side of the sleeve 11 so that the upper and lower surfaces of the insertion rod 15 are reversed. Rotate the limit rod 16 so that the limit rod 16 is engaged on the upper side of the insertion rod 15. Then the insertion rod 15 can be taken out from the inside of the sleeve 11. The insertion rod 15 on the other side is taken out in the same way. Since the lower side of the shock-absorbing mechanism 13 is fixedly connected to the extension column 12, the extension column 12 is slidably connected to the sleeve 11, and the extension column 12 is slidably connected to the connecting column 10. After the insertion rods 15 on both sides are taken out from the corresponding sleeves 11, push the carrier rod 1 upward so that the upper side of the carrier rod 1 is closely attached to the lower side of the cable tray body 9;

[0030] As Figure 1 , Figure 3 and Figure 5 shown in the figure, a plurality of mounting holes 14 are provided on the side of the extension column 12 for facilitating the insertion of the insertion rod 15 after adjusting the height. Insert the insertion rod 15 from the side of the sleeve 11 and then rotate the insertion rod 15. Since the limit rod 16 is rotatably connected to the insertion rod 15, the limit rod 16 will fall under the action of gravity at this time. When the cable tray body 9 vibrates, the insertion rod 15 will not fall off from the inside of the sleeve 11, enhancing the safety of the connection. When replacing this device and using it elsewhere, when the height is relatively high, the distance between the shock-absorbing mechanism 13 and the connecting column 10 can be shortened in the same way and then it can be put into use;

[0031] As Figure 2 , Figure 3 and Figure 4 shown in the figure, after the height is adjusted, it is also necessary to adjust the distance between the two clamping pieces 2 to facilitate clamping the cable tray body 9. Rotate the turning handle 4. The two sides of the turning handle 4 are fixedly connected with threaded rods 5. The threads on the threaded rods 5 on both sides of the turning handle 4 are arranged in the opposite direction, and the threaded rods 5 are also rotatably connected to the limit plates 3 on the lower side of the carrier rod 1. The two limit plates 3 on the lower side of the carrier rod 1 also play a role in limiting the threaded rods 5 to prevent the turning handle 4 from driving the threaded rods 5 to shift when the turning handle 4 is rotated. Since the threaded rods 5 are threadedly connected to the clamping pieces 2, and the clamping pieces 2 are slidably connected to the carrier rod 1 through the moving grooves 8 opened in the carrier rod 1, when the threaded rods 5 rotate, the clamping pieces 2 will move in the moving grooves 8. At this time, the clamping piece 2 on the other side will move the same distance, so that the two clamping pieces 2 clamp the cable tray body 9. In addition, when the clamping pieces 2 move to both sides in the initial state, the spring 7 between the clamping pieces 2 and the stop blocks 6 will undergo elastic deformation. When the cable tray body 9 is relatively large, the clamping pieces 2 play a role in clamping the cable tray body 9 under the combined action of the threaded rods 5 and the cable tray body 9, making the fixation more firm. When vibrating, the shock-absorbing mechanism 13 can play a buffering role.
