[0020] Example

[0021] See also Figure 1-4 The utility model provides an MPP cable protection tube which is easy to maintain, including an upper protection tube 1 and a lower protection tube 2. The lower protection tube 2 and the upper protection tube 1 are both arranged as semicircular arc structures. Both ends of the upper protection tube 1 and the lower protection tube 2 are connected by a connecting component. Auxiliary heat dissipation components are arranged on the inner sides of the upper protection tube 1 and the lower protection tube 2.

[0022] There are multiple groups of auxiliary heat dissipation components, each group of auxiliary heat dissipation components includes a heat-conducting elastic bellows 3 with one end fixedly connected to the inner side of the upper protection tube 1 and the lower protection tube 2, and the other end of the heat-conducting elastic bellows 3 is fixedly connected to the heat dissipation clamping plate 4, and a heat dissipation gasket 5 is fixedly arranged on the upper end of the heat dissipation clamping plate 4. The heat-conducting elastic bellows 3, the heat dissipation clamping plate 4 and the heat dissipation gasket 5 are all made of materials with good heat dissipation performance, which dissipate the heat generated by the cable and extend the life of the cable.

[0023] The connection assembly includes a connection rod 6 symmetrically arranged at the upper end of the upper protection tube 1. Six connection rods 6 are arranged and symmetrically distributed at the top ends of both sides of the upper protection tube 1, with three on each side and equidistantly distributed. A mounting groove 7 is provided on the upper part of the connection rod 6. A stopper 8 is fixedly connected at the middle position of the mounting groove 7. A slide bar 9 is fixedly arranged at both ends of the stopper 8. A slider 10 is slidably connected to the slide bar 9. The slider 10 is fixedly connected to the U-shaped plate 11. Both ends of the U-shaped plate 11 are fixedly connected to the mounting groove 7 through a compression spring 12. During the installation process, when the connection rod 6 enters the connecting groove 16, the U-shaped plate 11 is retracted into the mounting groove 7 and contacts the stopper 8 under the extrusion of the side wall of the connecting groove 16. When the top of the connection rod 6 enters the bottom of the connecting groove 16, a U-shaped groove matching the U-shaped plate 11 is arranged at the bottom of the connecting groove 16. At this time, the compression spring 12 pushes the U-shaped plate 11 into the U-shaped groove for engagement. When the upper protection tube 1 and the lower protection tube 2 are separated, the U-shaped plate 11 is again retracted into the installation groove 7 under the squeezing action of the side wall of the connecting groove 16 and contacts the stopper 8, and the connecting rod 6 smoothly escapes from the connecting groove 16.

[0024] A plug-in board 13 is fixedly arranged on the outer side of the connecting rod 6, and two plug-in boards 13 are arranged symmetrically on the top of both sides of the upper protection tube 1. The plug-in board 13 is fixedly connected to the upper end of the upper protection tube 1, and a clamping plate 14 is fixedly connected to the upper end of the plug-in board 13.

[0025] The upper end of the lower protective tube 2 is provided with a plug slot 15 and a connecting slot 16. The connecting slot 16 and the connecting rod 6 have the same shape and number. The plug slot 15 and the plug board 13 have the same shape and number. The connecting slot 16 is arranged on the inner side of the plug slot 15. A snap-fitting slot 17 is provided below the plug slot 15. The snap-fitting slot 17 is connected to the plug slot 15. The snap-fitting slot 17 and the snap board 14 have the same shape and number. The upper protective tube 1 and the lower protective tube 2 are connected together by the mortise and tenon structure, which is not easy to fall off and protects the cable.

[0026] Mounting plates 18 are fixedly provided at both ends of the upper protection tube 1 and the lower protection tube 2, and a long through hole 19 is provided in the middle of the mounting plate 18. The operator can place his fingers in the long through hole 19 and hold the mounting plate 18 to carry the upper protection tube 1 and the lower protection tube 2 and remove the upper protection tube 1 from the lower protection tube 2.

[0027] When in use, place the lower protection tube 2 at the installation site, and then place the cable to be protected on the heat dissipation pad 5 of the heat dissipation clamp 4. After placement, the operator lifts the upper protection tube 1 through the mounting plate 18 and places it above the lower protection tube 2, aligns the plug-in plate 13 with the plug-in slot 15, aligns the connecting rod 6 with the connecting slot 16, and slowly moves the upper protection tube 1 downward, so that the snap plate 14 enters the snap slot 17, and the connecting rod 6 enters the connecting slot 16. In this process, the U-shaped plate 11 enters the U-shaped slot at the bottom of the connecting slot 16 under the push of the compression spring 12, and the installation is now complete. When disassembly is required for maintenance, the operator can separate the upper and lower protection tubes by holding the mounting plates 18 at both ends.

[0028] Therefore, the utility model adopts the above-mentioned structure to provide an MPP cable protection tube that is easy to maintain. By setting a connecting component, the upper protection tube and the lower protection tube can be quickly installed and disassembled. During maintenance, it is only necessary to remove the upper protection tube from the lower protection tube, which is more convenient, easy to operate, and improves work efficiency.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
