[0035] like Figures 1-6 As shown, it illustrates a specific embodiment of this utility model:

[0036] Example 1

[0037] A modular cable tray connection protection device includes a first connecting part 1, a second connecting part 2, and a buckle plate 3. The first connecting part 1 has a U-shaped structure. The lower end of the first connecting part 1 has four fixing plates 11 with fixing holes 12. The four fixing plates 11 are connected to the end face of the first connecting part 1 in an arc-shaped connection 13. The second connecting part 2 is connected to the upper end of the first connecting part 1. The second connecting part 2 has a U-shaped structure. The two sides of the second connecting part 2 have snap-fit ​​edges 28. The buckle plate 3 snaps onto the snap-fit ​​edges 28 on both sides of the second connecting part 2.

[0038] In this embodiment, as Figure 1 As shown, this modular cable tray connection protection device includes a first connecting part 1, a second connecting part 2, and a buckle plate 3. The first connecting part 1, the second connecting part 2, and the buckle plate 3 enable the connection between the distribution cabinet or distribution panel and the cable tray. Figure 2 As shown, the four-sided fixing plate 11 at the lower end of the first connecting part 1 adopts an arc-shaped connection 13 to avoid cable damage caused by problems such as rough edges and burrs on the opening of the distribution panel or distribution box. The design of the snap-fit ​​edge 28 makes it easy to connect the buckle plate 3 to the front of the second connecting part 2. After the cable tray is connected, the buckle plate 3 is used to cover the front of the second connecting part 2, which improves the overall aesthetics of the cable tray connection and facilitates maintenance.

[0039] Example 2

[0040] Furthermore, mounting holes 14 are provided on the upper left side, right side, and back side of the first connecting part 1;

[0041] The second connecting part 2 is an adjustable design, including a back plate 21, a left fixed plate 22, a right fixed plate 23, a sliding assembly 24, a fixing screw 25, a left telescopic cover 26, and a right telescopic cover 27. The back plate 21 is fixedly connected to the upper back of the first connecting part 1 by bolts. There are four sets of sliding assemblies 24. The left fixed plate 22 and the right fixed plate 23 are each fixed using two sets of sliding assemblies 24. The fixing methods of the left fixed plate 22 and the right fixed plate 23 are the same. One set of sliding assemblies 24 is fixedly installed above the back plate 21, and the other set of sliding assemblies 24 is fixedly installed below the back plate 21. A snap-fit ​​edge 28 is provided on one side of the left fixed plate 22 and the right fixed plate 23. The other side is fixedly connected to the sliding assembly 24. There are four fixing screws 25. Two of the fixing screws 25 pass through the mounting holes 14 on the upper left side of the first connecting part 1 and are fixedly connected to the left fixing plate 22. The other two fixing screws 25 pass through the mounting holes 14 on the upper right side of the first connecting part 1 and are fixedly connected to the right fixing plate 23. The left telescopic cover 26 is located above the two left fixing screws 25. The left telescopic cover 26 is fixedly connected to the left fixing plate 22 on one side and fixedly connected to the left side of the first connecting part 1 on the other side. The right telescopic cover 27 is located above the two right fixing screws 25. The right telescopic cover 27 is fixedly connected to the right fixing plate 23 on one side and fixedly connected to the right side of the first connecting part 1 on the other side.

[0042] In this embodiment, as Figure 3 As shown, the adjustable design of the second connecting part 2 achieves the width adjustment of the second connecting part 2 by moving the left fixed plate 22 and the right fixed plate 23 on the sliding assembly 24. The lower part is supported by the fixing screw 25 to fix the left telescopic cover 26 and the right telescopic cover 27, thus making it suitable for cable trays of different lengths and sizes, with a wide range of applications.

[0043] Furthermore, the sliding component 24 includes a slide rail 241 and a slider 242. The slide rail 241 is fixedly connected to the back plate 21, and the slider 242 is slidably connected inside the slide rail 241. The upper end face of the slider 242 is connected to the left fixed plate 22 or the right fixed plate 23.

[0044] In this embodiment, as Figure 3 , Figure 5As shown, when the width of the second connecting part 2 needs to be adjusted, the slider 242 of the sliding component 24 is first moved within the slide rail 241. This causes the left fixing plate 22 and the right fixing plate 23 connected to the upper surface of the slider 242 to move left and right. With the movement of the left fixing plate 22 and the right fixing plate 23, the left telescopic cover 26 connected to the left side of the left fixing plate 22 and the left side of the first connecting part 1 is compressed or expanded, and the right telescopic cover 27 connected to the right side of the right fixing plate 23 and the right side of the first connecting part 1 is compressed or expanded. Finally, after the position is adjusted, the left fixing plate 22 and the right fixing plate 23 are fixed in position using the fixing screw 25. The operation is simple, easy to apply in practice, and improves work efficiency.

[0045] Furthermore, the buckle 3 is an adjustable buckle, including a left connecting plate 31, a telescopic cover 32, and a right connecting plate 33. The left connecting plate 31 and the right connecting plate 33 are respectively fixedly connected to both sides of the telescopic cover 32. The left connecting plate 31 and the right connecting plate 33 have the same structure, and their ends away from the telescopic cover 32 are provided with snap-fit ​​grooves 34 that are adapted to the snap-fit ​​edges 28 on both sides of the second connecting part 2.

[0046] In this embodiment, as Figure 4 As shown, the connection design between the left connecting plate 31 and the right connecting plate 33 and the telescopic cover 32 allows the buckle plate 3 to be adjusted in length, thereby corresponding to the width of the adjusted second connecting part 2.

[0047] Furthermore, magnets are provided on both sides of the left telescopic cover 26 and the right telescopic cover 27, which are attracted between the first connecting part 1 and the left fixing plate 22 and the right fixing plate 23.

[0048] In this embodiment, the left telescopic cover 26 and the right telescopic cover 27 are connected by magnetic adsorption, making them easy to handle.

[0049] Example 3

[0050] Furthermore, the first connecting part 1 and the second connecting part 2 are integrally formed.

[0051] In this embodiment, as Figure 6 As shown, the first connecting part 1 and the second connecting part 2 are integrally formed. This modular cable tray connection protection device can adopt an integrated design or a segmented connection design for the first connecting part 1 and the second connecting part 2, which supports quick splicing and disassembly and improves work efficiency.

[0052] Example 4

[0053] Furthermore, the first connecting part 1, the second connecting part 2, and the buckle plate 3 are coated with flame-retardant material on both the inner and outer surfaces to improve the fire resistance rating.

[0054] Furthermore, the protective device also includes fire-retardant putty.

[0055] In this embodiment, after connecting the cable tray using the protective device, you can choose to directly seal it with fireproof putty without sealing it, depending on the actual usage scenario, to facilitate heat dissipation, or you can use the buckle plate 3 to seal it and maintain its aesthetics. The buckle plate 3 is an optional design, which is flexible in application and suitable for different scenarios.

[0056] In this embodiment, the measures of coating the material surface with flame-retardant material and sealing it with fireproof putty after connection can improve the fire resistance rating, ensure on-site safety, and reduce the occurrence of safety accidents.

[0057] Example 5

[0058] Furthermore, the width of the second connecting part 2 is smaller than the width of the first connecting part 1, and the thickness of the buckle plate 3 is equal to the thickness of the first connecting part 1.

[0059] In this embodiment, the thickness of the buckle plate 3 is the same as the thickness of the first connecting part 1. This ensures that the buckle plate 3 rests on the ground and the upper surface of the first connecting part 1 after being fastened, thus ensuring reliable and effective use.
