[0017] The utility model is further described below in connection with the drawings:

[0018] Example 1:

[0019] Please refer to Figures 1-4 : in the embodiment, a kind of MPP cable protection pipe convenient to combine extension, including first straight pipe 1 and second straight pipe 4, the inner wall of first straight pipe 1 and the outer wall of second straight pipe 4 are fixedly connected, the material quality of first straight pipe 1 and second straight pipe 4 is all modified polypropylene, the outer wall front of first straight pipe 1 is connected with butt joint structure 2, the inner wall of second straight pipe 4 is connected with support structure 3.

[0020] Butt joint structure 2 includes sleeve ring 201 and slot 202, the inner wall rear of sleeve ring 201 and the outer wall front of first straight pipe 1 are fixedly connected, the material quality of sleeve ring 201 is modified polypropylene, sleeve ring 201 inner wall top front is processed with slot 202, the inner wall top of slot 202 is fixedly connected with round bar 203;

[0021] When the first straight pipe 1 is rotated to the left, the round rod 203 enters the bending part of the sliding groove 6, and the butted MPP cable pipe forms a clamping connection, which realizes the convenient combination and extension of multiple MPP cable protection pipes and eliminates the use limitations of multiple MPP cable protection pipes.

[0022] The top rear of the first straight pipe 1 is fixedly connected with the bent plate 5, and the top of the bent plate 5 is processed with the sliding groove 6. The support structure 3 includes the first circular ring 301 and the straight plate 302. The outer wall of the first circular ring 301 is fixedly connected with the inner wall of the second straight pipe 4, and the inner wall of the first circular ring 301 is fixedly connected with the outer side of the multiple straight plates 302. The inner side of the straight plate 302 is fixedly connected with the second circular ring 303. The first circular ring 301, the straight plate 302 and the second circular ring 303 form multiple support spaces, which can separate and place the cables.

[0023] Working principle:
