[0007] By adopting the above technical solution, the precise alignment of the sleeve can be achieved through the cooperation of the positioning groove and the positioning block, and the locking block and locking hole facilitate bolt fixing, thereby improving the stability of the overall structure and the installation efficiency.

[0008] Preferably, the heights of the two sets of locking blocks on the sleeve body differ by the height of one locking block.

[0009] By adopting the above technical solution, the design allows the locking blocks to form a stable stacked structure after stacking, which facilitates the use of bolts to pass through the locking holes for fastening, avoids loosening in a vibration environment, and improves the convenience and reliability of installation.

[0010] Preferably, an alignment hole is provided at the bottom of one side of the sleeve, and a positioning post is fixedly provided on one side of the sleeve and below the alignment hole. An alignment hole and a positioning post in opposite positions are provided on the other side of the sleeve.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] A plastic heat insulation sleeve includes a sleeve body 1, which is made of heat-insulating plastic and is semi-tubular. By splicing two sets of sleeve bodies 1 together, it can be well connected to the pipeline, thereby achieving a good heat insulation effect. A connecting part 2 is fixedly connected to the top of the sleeve body 1, and a connecting ring 3 is fixedly connected to the top of the connecting part 2, which can connect multiple spliced ​​sleeve bodies 1 and thus be fitted onto a longer pipeline. A positioning groove 4 is provided on one side of the sleeve body 1, and a positioning block 5 that matches the positioning groove 4 is provided on the other side of the sleeve body 1, which can improve the interlocking effect between two sleeve bodies 1. Locking blocks 6 are fixedly connected to both sides of the outer wall of the sleeve body 1, and locking holes 7 are provided inside the locking blocks 6, which can be well interlocked between two sleeve bodies 1 by inserting bolts or other means.

[0029] Furthermore, the height difference between the two sets of locking blocks 6 on the sleeve 1 is the height of one locking block 6, so that when the two sets of sleeves 1 are spliced, the two locking blocks 6 can be stacked in a staggered manner, and then the two sets of locking blocks 6 can be locked and fixed through the locking hole 7.

[0030] Furthermore, an alignment hole 8 is provided at the bottom of one side of the sleeve 1, and a positioning post 9 is fixedly provided on one side of the sleeve 1 and below the alignment hole 8. On the other side of the sleeve 1, an alignment hole 8 and a positioning post 9 are provided in opposite positions, thereby making the splicing effect between the two sets of sleeves 1 better.

[0031] Furthermore, a pre-connection groove 10 is provided on one side of the sleeve ring 3, and a fractal block 11 is fixedly connected to one side of the sleeve ring 3 and inside the pre-connection groove 10. A snap-fit ​​block 12 is fixedly connected to the other side of the sleeve ring 3, and an insertion groove 13 is provided in the middle of the snap-fit ​​block 12. When the two sets of sleeve rings 3 are spliced ​​together, the snap-fit ​​block 12 is inserted into the pre-connection groove 10, and then the fractal block 11 enters into the insertion groove 13, pushing the two sides of the snap-fit ​​block 12 outwards respectively, thereby improving the connection strength between the snap-fit ​​block 12 and the pre-connection groove 10.

[0032] Furthermore, wedge-shaped portions 15 are provided on both sides of the fractal block 11, which can better separate the two sides of the snap-fit ​​block 12 and improve the snap-fit ​​effect.

[0033] Furthermore, locking parts 14 are fixedly connected to both sides of the snap-fit ​​block 12, and a locking groove 16 is provided on one side of the sleeve ring 3 and inside the pre-connection groove 10. After the snap-fit ​​block 12 is fully inserted into the pre-connection groove 10, the locking part 14 can enter the locking groove 16 to achieve stable pre-fixation.

[0034] The implementation principle of this embodiment is as follows: When in use, the two semi-tubular sleeves 1 are first engaged with each other through the positioning groove 4 and the positioning block 5, and the positioning post 9 is inserted into the alignment hole 8 to achieve initial alignment; then, the locking blocks 6 are stacked in a staggered manner and fixed by bolts inserted into the locking hole 7 to form a complete heat insulation sleeve. For long pipes, the bottom of the sleeve 1 is inserted into the sleeve ring 3 on the other sleeve 1 to achieve mutual connection. The snap-fit ​​block 12 is inserted into the pre-connection groove 10, and the wedge-shaped part 15 of the fractal block 11 expands the snap-fit ​​block 12 to make it tightly snap-fit. At the same time, the locking part 14 enters the locking groove 16 to achieve pre-fixation and ensure a stable connection. The whole process is simple to operate, the modular design adapts to different pipe lengths, and the heat insulation plastic effectively reduces heat conduction and improves energy efficiency.
