[0002] In modern buildings, industrial plants, and various infrastructure constructions, the laying and protection of cables are crucial. Metal cable trays, as key equipment for supporting and protecting cables, are widely used in various fields. However, traditional metal cable trays are usually only connected and fixed with connecting plates during installation. This connection method has poor stability. When the cable tray is subjected to factors such as vibration, pressure, and temperature changes over a long period of time, the connection is prone to loosening. For example, in the production workshops of some large factories, the problem of loosening at the connection of traditional cable trays is particularly prominent due to the continuous vibration generated by the frequent operation of machinery and equipment. This may not only cause the cables to shift within the cable tray, affecting their normal operation, but may also cause safety hazards. At the same time, unstable connections will also reduce the overall stability of the metal cable tray, shorten its service life, and increase the later maintenance costs. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1:

[0032] Please see Figures 1-8As shown, this utility model provides an assembled metal cable tray, including: a U-shaped channel frame 1, a cover plate 2, and a connecting piece 3;

[0033] The U-shaped trough frame 1 has first mounting holes 4 at both ends on both sides, and trough frame plates 13 are fixedly connected to both ends of the top of the U-shaped trough frame 1. The surface of the trough frame plate 13 has a first groove 14, and a bending plate 17 is provided on the surface of the trough frame plate 13 away from the first groove 14.

[0034] The bending plate 17 has a second slot 10 at the middle end, a positioning block 18 is movably inserted on the surface of the second slot 10, a receiving cavity 21 is opened at the upper end of the positioning block 18, a locking block 19 is slidably connected to the surface of the receiving cavity 21, and a pressure spring 22 is fixedly connected between the surface of the locking block 19 and the surface of the receiving cavity 21.

[0035] Both sides of the cover plate 2 are provided with side plates 11, and the surface of the side plates 11 is provided with limit holes 12;

[0036] The surface of the connecting piece 3 is provided with a second mounting hole 5, and a first bolt 6 is movably inserted into the surface of the second mounting hole 5. A locking nut 8 is threaded onto the surface of the first bolt 6.

[0037] In this technical solution, when assembling two sets of U-shaped slot frames 1, by pushing the locking block 19 along the surface of the receiving cavity 21, the pressure spring 22 is compressed until the locking block 19 can be fully inserted into the receiving cavity 21. Then, the positioning block 18 can be removed downwards from the second slot 10 on the bending plate 17. The two sets of U-shaped slot frames 1 are then joined end-to-end, ensuring that the first slot 14 on one side of the slot frame plate 13 is perpendicularly aligned with the second slot 10 on the other side of the bending plate 17. Simultaneously, by inserting the positioning block 18 from bottom to top into the second slot 10 and the first slot 14, when the locking block 19 is above the first slot 14, the tension of the pressure spring 22 causes the locking block 19 to extend to one side of the positioning block 18 and contact the top of the slot frame plate 13. This allows for positioning and initial fixation of the two sets of U-shaped slot frames 1 during assembly, ensuring the two sets of U-shaped slot frames 1 are properly positioned. There will be no relative displacement between them. Then, the personnel can use the first bolt 6 and the locking nut 8 to lock and fix the connecting piece 3 to the connection of the two sets of U-shaped channel frames 1 through the first mounting hole 4 and the second mounting hole 5. This can further install and fix the U-shaped channel frame 1, ensuring the stability of the U-shaped channel frame 1 assembly. At the same time, the personnel can place the cover plate 2 above the U-shaped channel frame 1 and the channel frame plate 13, and push the cover plate 2 to drive the side plate 11 to move. When the side plate 11 moves, it can contact the inclined surface of the locking block 19 and push the locking block 19 to compress the pressure spring 22 until the cover plate 2 and the top of the channel frame plate 13 are in contact. At the same time, the limiting insertion hole 12 on the side plate 11 can be on one side of the locking block 19. Under the push of the tension of the pressure spring 22, the locking block 19 can be inserted into the limiting insertion hole 12, thereby limiting the side plate 11 and the cover plate 2 and enhancing the stability of the connection between the cover plate 2 and the U-shaped channel frame 1.

[0038] It should be noted that the initial state of the pressure spring 22 is the compressed state, which means that the pressure spring 22 can exert a large force on the locking block 19, ensuring that the locking block 19 can always be inserted into the limiting socket 12 when the whole is subjected to vibration.

[0039] Example 2:

[0040] Based on Embodiment 1, this utility model is as follows: Figures 1-8As shown, the U-shaped trough frame 1 has heat dissipation holes 15 on both sides, and there are multiple heat dissipation holes 15, which are evenly distributed on the surface of the U-shaped trough frame 1. The bottom of the receiving cavity 21 has a guide groove 23. The bottom of the locking block 19 is fixedly connected to a guide block 25. The surface of the guide block 25 is slidably connected to the surface of the guide groove 23. The bottom of the positioning block 18 is fixedly connected to a contact plate 24. The top of the contact plate 24 contacts the bottom of the bending plate 17. The top of the positioning block 18 has a second threaded hole 20. The middle of the trough frame plate 13 has a first threaded hole 16. The two ends of the cover plate 2 are movably inserted with second bolts 9.

[0041] In this technical solution, the heat dissipation through hole 15 facilitates the dissipation of heat generated by the cable in the U-shaped trough 1 during use to the outside, effectively reducing the working temperature of the cable. The guide groove 23 and guide block 25 guide the locking block 19, preventing the locking block 19 from coming loose from the inside of the receiving cavity 21. The contact plate 24 limits the positioning between the bottom of the positioning block 18 and the bending plate 17. The first threaded hole 16, the second threaded hole 20, and the second bolt 9 facilitate the installation and fixation of the cover plate 2, the trough plate 13, and the positioning block 18 after the connection between the cover plate 2 and the U-shaped trough 1 is completed.

[0042] Example 3:

[0043] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the two side plates 11 are provided with abutting ribs 26 on the side that are close to each other. The limiting insertion hole 12, the first slot 14 and the second slot 10 are all rectangular in shape. There are four connecting pieces 3. The lower end of the connecting piece 3 is provided with a bent part 7.

[0044] In this technical solution, by setting the tightening rib 26, during the connection between the cover plate 2 and the U-shaped channel frame 1, the tightening rib 26 can be located on one side of the side plate 11 to tighten and press against the U-shaped channel frame 1, thereby improving the tightness of the connection between the cover plate 2 and the side plate 11 and the U-shaped channel frame 1. By setting the bending part 7, the strength of the connecting piece 3 is effectively improved. At the same time, during the installation between the connecting piece 3 and the U-shaped channel frame 1, the bending part 7 can provide corresponding support to the bottom of the U-shaped channel frame 1.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
