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.

[0031] Referring to Figures 1 to 2 As shown, an embodiment provided by the present utility model: an adjustable cable tray includes a ladder rack 1, and an installation component for supporting the ladder rack 1 is fixedly connected to the outside of the ladder rack 1. The installation component includes two trays 2, the outside of the trays 2 is fixedly connected to the bottom of the ladder rack 1, two mounting plates 3 are fixedly connected to the top of the trays 2, a ladder rack 2 5 is slidably connected to the inside of the ladder rack 1, and a sliding component for limiting the ladder rack 2 5 is arranged inside the ladder rack 1. The ladder rack 1 and the ladder rack 2 5 are made of high-strength metal materials, having good load-bearing capacity and stability. The sliding component includes a chute 4, the outside of the chute 4 is opened inside the ladder rack 1, a slide block 6 is slidably connected to the inside of the chute 4, with high matching precision to ensure smooth sliding without jamming, so as to ensure the reliability of long-term use. The top of the slide block 6 is fixedly connected to the bottom of the ladder rack 2 5, and the outside of the slide block 6 is slidably connected to the inside of the ladder rack 1. A stopper 7 is fixedly connected to the inside of the ladder rack 1 to provide an effective limiting function without affecting normal telescoping.

[0032] Referring to Figures 3 to 4As shown, a plurality of card slots 8 are provided at the top of the ladder frame 1. The card slots 8 are for engaging with the card blocks 13. An installation groove 9 is provided inside the ladder frame 2 5. The installation groove 9 is for installing the sleeve 10. Two sleeves 10 are fixedly connected inside the installation groove 9. The sleeves 10 and the cylindrical sleeve 12 are for preventing the first spring 11 from deforming. A first spring 11 is arranged inside the sleeve 10. The first spring 11 is for cooperating with the cylindrical sleeve 12 to eject the card block 13, so that the card block 13 engages with the card slot 8. One side of the first spring 11 is fixedly connected inside the sleeve 10, and the other side of the first spring 11 is fixedly connected inside the cylindrical sleeve 12. The cylindrical sleeve 12 is slidably connected inside the sleeve 10. The tops of the two cylindrical sleeves 12 are fixedly connected with the card blocks 13. The outside of the card block 13 is slidably connected inside the installation groove 9, and the outside of the card block 13 is engaged with the inside of the card slot 8.

[0033] Referring to Figures 4 to 5 As shown, two mounting blocks 14 are fixedly connected inside the ladder frame 2 5. The mounting blocks 14 are for connecting the fixing plate 15. The tops of the two mounting blocks 14 are fixedly connected with the fixing plate 15. A limiting groove 16 is provided outside the mounting block 14. A limiting block 17 is slidably connected inside the limiting groove 16, which can ensure that unnecessary displacement does not occur to each component during the working process. The outside of the limiting block 17 is slidably connected inside the mounting block 14. The bottom of the telescopic rod 21 is fixedly connected inside the ladder frame 2 5. The adjacent sides of the two limiting blocks 17 are fixedly connected with a connecting plate 18. The connecting plate 18 is for cooperating with the second protective pad 20 to push against the outside of the cable;

[0034] A plurality of first protective pads 19 are fixedly connected to the bottom of the fixing plate 15. A plurality of second protective pads 20 are fixedly connected to the top of the connecting plate 18. Two telescopic rods 21 are fixedly connected to the bottom of the connecting plate 18. A second spring 22 is sleeved outside the telescopic rod 21. The telescopic rod 21 is for cooperating with the second spring 22 to push against the connecting plate 18, so that the connecting plate 18 fits more closely to the outside of the cable.

[0035] Working principle: First of all, the ladder frame 1 and the ladder frame 2 5 are the main components of the cable tray. When it is necessary to adjust the length of the cable tray, the ladder frame 1 and the ladder frame 2 5 can be telescoped. The slider 6 on the ladder frame 2 5 slides in the chute 4 of the ladder frame 1 to realize the relative movement between the two, and at the same time, the limiting is carried out. The stop block 7 can prevent the slider 6 from sliding excessively and play a preliminary limiting role.

[0036] When the ladder frame 1 and the ladder frame 5 are adjusted to the appropriate positions, the limiting mechanism composed of the sleeve 10, the first spring 11, the cylindrical sleeve 12 and the clamping block 13 starts to function. The first spring 11 is in a compressed state, pushing the cylindrical sleeve 12 and the clamping block 13 to move upward. The clamping block 13 is engaged with the clamping groove 8 on the ladder frame 1, thereby realizing the limiting and fixing between the ladder frame 1 and the ladder frame 5, and ensuring that no accidental sliding occurs during use.

[0037] When installing and placing the cable, the tray 2 can play a role in supporting the cable. The mounting plate 3 can mount the tray 2, and then the mounting groove 9 on the mounting block 14 can mount some separating components to classify and organize the cables, so as to avoid the entanglement of different types of cables and improve the orderliness of the cable layout.

[0038] At the same time, the telescopic rod 21 and the second spring 22 can push the connecting plate 18, so that the first protective pad 19 and the second protective pad 20 can protect the outside of the cable placed inside the ladder frame 1 and the ladder frame 5. The first protective pad 19 and the second protective pad 20 can buffer the external impact force and reduce the damage to the cable.

[0039] The cooperation of the limiting groove 16 and the limiting block 17 can further ensure the stability of each component during operation, prevent unnecessary displacement, and the connecting plate 18 plays a role in connection and reinforcement, making the entire bridge structure more firm. At the same time, it also provides a certain elastic support for the bridge, and at the same time provides good protection for the outside of the cable, providing a reliable guarantee for the safe laying of the cable.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
