[0002] The petroleum cracking tube is a long steel bar with a hollow cross-section and no seams around. The petroleum cracking tube is an economical cross-section steel. The petroleum cracking tube is also an indispensable material for various conventional weapons. Barrels of guns, artillery barrels, etc. are all made of petroleum cracking tubes. Most of the petroleum cracking tubes are tube bodies with high temperature resistance and corrosion resistance. During transportation, the petroleum cracking tubes will collide with each other, resulting in easy damage to their surfaces. Therefore, it is necessary to solve this problem. The utility model provides a high-temperature resistant cracking furnace tube provided with a stable connection structure. Content of the Utility Model

[0003] The purpose of the utility model is to provide a high-temperature resistant cracking furnace tube provided with a stable connection structure to solve the problems raised in the above background art.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: A high-temperature resistant cracking furnace tube provided with a stable connection structure includes a tube body. A plurality of positioning sleeves are arranged on the tube body. Arc-shaped positioning grooves adapted to the arc-shaped surfaces thereof are arranged on adjacent sides of the positioning sleeves. The tube body is limitedly installed through the cooperation between the arc-shaped surface of the positioning sleeve and the arc-shaped positioning groove.

[0005] A plurality of arc-shaped elastic blocks are arranged at intervals along the circumference on the inner side surface of the positioning sleeve.

[0006] Clamping grooves are arranged in the arc-shaped positioning grooves on adjacent sides of the positioning sleeve, and clamping blocks matched with the clamping grooves are arranged on the other two adjacent sides.

[0007] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: A plurality of positioning sleeves are arranged on the tube body of the utility model. Arc-shaped positioning grooves adapted to the arc-shaped surfaces thereof are arranged on adjacent sides of the positioning sleeves. The tube body is limitedly installed through the cooperation between the arc-shaped surface of the positioning sleeve and the arc-shaped positioning groove. Through the adaptation of the arc-shaped surface of the positioning sleeve itself and the arranged arc-shaped positioning groove, the installation and connection stability between adjacent tube bodies is improved. Clamping grooves are arranged in the arc-shaped positioning grooves on adjacent sides of the positioning sleeve, and clamping blocks matched with the clamping grooves are arranged on the other two adjacent sides. The clamping blocks are directly clamped in the clamping grooves, which further improves the installation and connection stability between adjacent tube bodies. Description of the Drawings
