At the same time, it is convenient to support the flame-retardant protective pipe shell body 1 so that it can be applied to pipes 13 of different diameters, with stronger applicability. Moreover, it is convenient to move and rotate and adjust the flame-retardant protective pipe shell body 1, making the use more convenient and fast; it is convenient to connect and fix two adjacent flame-retardant protective pipe shell bodies 1, and the ends of the two flame-retardant protective pipe shell bodies 1 can be made to abut against each other, which can ensure the installation efficiency and quality.

[0034] The connecting mechanism includes semi-circular rings 204 fixedly sleeved on the side walls of the first half shell 101 and the second half shell 102. A through hole 201 is formed in the side wall of the semi-circular ring 204, and an internal thread 202 is provided in the through hole 201.

Then, the flame-retardant protective pipe shell body 1 is pushed to rotate. When the threaded rod 203 is aligned with the through hole 201, the rotating rod 1201 continues to rotate, so as to drive the threaded rod 203 to rotate through the moving mechanism, and the threaded rod 203 can be screwed into the internal thread 202, thereby pulling the end of the flame-retardant protective pipe shell body 1 to abut against the end of the previous flame-retardant protective pipe shell body 1, which is convenient to connect and fix two adjacent flame-retardant protective pipe shell bodies 1, and the ends of the two flame-retardant protective pipe shell bodies 1 can be made to abut against each other, which can ensure the installation efficiency and quality.

[0035] The support mechanism includes a plurality of moving columns 701 arranged on the inner side wall of the flame-retardant protective pipe shell body 1. The moving columns 701 are connected to the inner side wall of the flame-retardant protective pipe shell body 1 through a telescopic mechanism, and a first ball 702 is arranged at the end of the moving column 701. When the second half shell 102 rotates and closes with the first half shell 101, when the first ball 702 abuts against the side wall of the pipeline 13, the moving column 701 can perform telescopic movement, so as to facilitate the support of the flame-retardant protective pipe shell body 1, enabling it to be applicable to pipelines 13 with different diameter sizes, with stronger applicability.

The rotating rod 1201 is rotatably connected to the side wall of the fixed block 401, and a handwheel 402 is fixedly connected to one end of the rotating rod 1201. By rotating the handwheel 402, the rotation of the handwheel 402 drives the rotating rod 1201 to rotate.

A moving block 503 is connected to the side wall of the support plate 501 through a moving component. A moving rod 1206 is fixed to the side wall of the moving block 503. An external thread 502 is arranged on the outer side wall of the rotating rod 1201, and the moving block 503 is threadedly connected to the external thread 502. When the rotating rod 1201 rotates, it drives the external thread 502 to rotate.

[0038] The moving component includes a guide rail 601 fixedly connected to the side wall of the support plate 501. A guide groove 602 is formed in the side wall of the moving block 503, and the guide rail 601 is inserted into the guide groove 602 to play a guiding role in the movement of the moving block 503.

[0039] The second moving mechanism includes a plurality of slots 301 arranged in an array on the side wall of the rotating rod 1201. An insertion rod 302 is inserted into each slot 301. The other end of the insertion rod 302 is fixed to the end of the threaded rod 203. An elastic member is arranged between the threaded rod 203 and the rotating rod 1201. After the first half shell 101 and the second half shell 102 are closed, the flame-retardant protective pipe shell body 1 is pushed to move, so that the end of the threaded rod 203 abuts against the end of the semi-circular ring 204. Then, the flame-retardant protective pipe shell body 1 is pushed to rotate. When the threaded rod 203 is aligned with the through hole 201, the threaded rod 203 can be inserted into the through hole 201 under the action of the elastic member and abut against the internal thread 202. At the same time, the insertion rod 302 slides in the slot 301.

[0040] The elastic member includes a first spring 9 fixedly connected to the end of the rotating rod 1201, and the other end of the first spring 9 is fixedly connected to the end of the threaded rod 203, so that the end of the threaded rod 203 abuts against the end of the semi-circular ring 204, and the first spring 9 is compressed.

[0041] The telescopic mechanism includes a sleeve 801 fixedly connected to the inner side wall of the flame-retardant protective tube body 1. A moving column 701 is inserted into the sleeve 801, and a second spring 802 is fixedly connected between the moving column 701 and the sleeve 801. When the first ball 702 abuts against the side wall of the pipeline 13, the moving column 701 can slide into the sleeve 801, and at the same time, the second spring 802 is compressed.

[0042] The other end of the push pin 1203 is provided with a second ball 10, and the second ball 10 slides in the sliding groove, so that the push pin 1203 slides more smoothly in the sliding groove.

[0043] Working principle: When in use, when the flame-retardant protective tube body 1 needs to be installed, first, the first half shell 101 is sleeved on the side wall of the pipeline 13. Then, the rocker 402 is rotated. The rotation of the rocker 402 drives the rotating rod 1201 and the external thread 502 to rotate. At this time, the moving block 503 can be driven to move along the guide rail 601 in the direction close to the rotating block 1202, and the push pin 1203 is driven by the moving rod 1206 to slide along the spiral groove 1204 into the horizontal groove 1205. At this time, the rotating block 1202 can be pushed to flip 180 degrees, driving the second half shell 102 to flip and close with the first half shell 101, making the installation of the flame-retardant protective tube body 1 more convenient and fast;

[0044] At the same time, when the first ball 702 abuts against the side wall of the pipeline 13, the moving column 701 can slide into the sleeve 801, and at the same time, the second spring 802 is compressed, so as to facilitate the support of the flame-retardant protective tube body 1, enabling it to be applicable to pipelines 13 with different diameters, with stronger applicability. And, under the action of the first ball 702, it is convenient to move and rotate the flame-retardant protective tube body 1, making the use more convenient and fast;

[0045] After the first half shell 101 and the second half shell 102 are closed, the flame-retardant protective tube body 1 is pushed to move, so that the end of the threaded rod 203 abuts against the end of the semi-circular ring 204, and the first spring 9 is compressed. Then, the flame-retardant protective tube body 1 is pushed to rotate. When the threaded rod 203 is aligned with the through hole 201, the threaded rod 203 can be inserted into the through hole 201 under the action of the first spring 9 and abut against the internal thread 202;

[0046] Next, continue to rotate the crank wheel 402. The rotation of the crank wheel 402 drives the rotation of the rotating rod 1201. At this time, the push pin 1203 can continue to move along the horizontal groove 1205, so as to drive the threaded rod 203 to rotate through the moving mechanism, and the threaded rod 203 can be screwed tightly into the internal thread 202, thereby pulling the end of the flame-retardant protective tube body 1 to abut against the end of the previous flame-retardant protective tube body 1, which is convenient for connecting and fixing two adjacent flame-retardant protective tube bodies 1. Moreover, the ends of the two flame-retardant protective tube bodies 1 can be made to abut against each other, which can ensure the installation efficiency and quality.

[0047] Moreover, when installing the first flame-retardant protective tube body 1, the threaded tube 15 can be installed on the wall 14 first, and then the threaded rod 203 can be screwed into the threaded tube 15 so that the flame-retardant protective tube body 1 abuts against the wall 14.
