[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0026] Combine Figure 1 The utility model is a tray-type cable tray with a shield, comprising a built-in tray rack 1, an external extension tray rack 2 is sleeved on the side of the built-in tray rack 1, a straight plate shield 3 is clamped between the built-in tray rack 1 and the external extension tray rack 2, the built-in tray rack 1 comprises a built-in U-shaped rack 11, and threaded connectors 13 are threaded on both sides of the built-in U-shaped rack 11, the external extension tray rack 2 comprises an external U-shaped rack 21 slidably arranged between the built-in U-shaped rack 11 and the threaded connector 13, the external U-shaped rack 21 and the built-in U-shaped rack 11 are sleeved on each other, and the straight plate shield 3 is inserted between the built-in U-shaped rack 11 and the external U-shaped rack 21.

[0027] Specifically, the built-in U-shaped frame 11 and the external U-shaped frame 21 are slidably engaged and limited by a threaded connector 13, and the insertion setting of the straight plate shield 3 is used to squeeze and fix the built-in U-shaped frame 11 and the external U-shaped frame 21. At the same time, the straight plate shield 3 is also used to protect the internal cables of the built-in U-shaped frame 11 and the external U-shaped frame 21. The built-in U-shaped frame 11 and the external U-shaped frame 21 in this structure cooperate with each other, the structure is simple, and the built-in U-shaped frame 11 and the external U-shaped frame 21 can be infinitely staggered and connected, and the connection length is adjustable to meet the support requirements of cables of different lengths.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Combine Figure 2-Figure 5 The built-in tray rack 1 also includes multiple groups of heat dissipation slots 12 opened on the bottom surface of the built-in U-shaped rack 11. The multiple groups of heat dissipation slots 12 are opened side by side. The multiple groups of heat dissipation slots 12 are opened on the bottom surface of the built-in U-shaped rack 11 to achieve cable heat dissipation.

[0031] The built-in pallet rack 1 also includes a threaded connector 13 threadedly connected to the lower end of the built-in U-shaped frame 11. One side of the threaded connector 13 is provided with a threaded rod 131. The threaded rod 131 is inserted into the built-in U-shaped frame 11 and rotated for connection. The diameter of the threaded connector 13 is larger than the opening diameter of the slide groove 22, which limits the socketing of the external U-shaped frame 21 and the built-in U-shaped frame 11.

[0032] Side guide rails 111 are fixedly provided on both sides of the built-in U-shaped frame 11, and first side panels 112 are fixedly provided on both sides of the upper end of the built-in U-shaped frame 11. The side guide rails 111 are slidably engaged with the external U-shaped frame 21, and the first side panel 112 is provided at the upper end and fits with the lower end of the straight plate shield 3.

[0033] Connecting rings 113 are fixedly provided on both sides of the lower end of the built-in U-shaped frame 11. A threaded opening 1131 is provided in the connecting ring 113, and the threaded opening 1131 is threadedly connected to the threaded rod 131. The diameter of the connecting ring 113 matches the width of the slide groove 22. The threaded connection between the threaded rod 131 and the threaded opening 1131 enables the external extension tray rack 2 to be slidably connected between the built-in U-shaped frame 11 and the threaded connector 13.

[0034] Example 2:

[0035] Combine Figure 2-Figure 6 A slide groove 22 is provided at the bottom center of the external U-shaped frame 21, and heat dissipation long grooves 23 are provided on both sides of the bottom. The slide groove 22 provides sliding limit for the external U-shaped frame 21. At the same time, the slide groove 22 and the heat dissipation long groove 23 can overlap with the heat dissipation groove 12 up and down to ensure the heat dissipation effect.

[0036] Guide rail grooves 211 are provided on both sides of the interior of the external U-shaped frame 21, and second side panels 212 are fixedly provided on both sides of the upper end of the external U-shaped frame 21. The side guide rails 111 slide and engage in the guide rail grooves 211 to horizontally limit the sliding of the external U-shaped frame 21. The upper end of the straight plate shield 3 is arranged in contact with the second side panel 212. The second side panel 212 and the first side panel 112 are matched to reserve insertion space for the straight plate shield 3. At the same time, the insertion of the straight plate shield 3 can further lock the internal U-shaped frame 11 and the external U-shaped frame 21.

[0037] The side guide rails 111 are not of the same length as the internal U-shaped frame 11, and the starting position of the side guide rails 111 is staggered with the connecting ring 113. The shorter setting of the side guide rails 111 allows the side guide rails 111 to be inserted into the guide rail groove 211 for guidance only after the connecting ring 113 is sleeved in the sliding groove 22, so that the external U-shaped frame 21 and the internal U-shaped frame 11 can be smoothly sleeved.
