One end of the four driven blocks 8 is respectively plugged into the four fixed grooves 19, and the bottom end of the fixing ring 4 is fixed to the top of the high-temperature felt body 11, and the outer surface of the high-temperature felt body 11 is plugged into the inner part of the outer sleeve 1, wherein, by providing the push block 6, the driven block 8 can be pushed into the fixing groove 19 under the drive of the adjusting ring 5, so as to fix the high-temperature felt body 11.

[0022] like Figure 3 and Figure 4 As shown, the top of the adjusting ring 5 is fixedly connected to an adjusting rod 14, and a fixing bolt 15 is slidably provided on the outer surface of the adjusting rod 14. Two positioning grooves 18 are provided on the top of the fixing ring 4, and the fixed end of the fixing bolt 15 is plugged into any one of the positioning grooves 18. By providing the fixing bolt 15, the fixing ring 4 can be fixed by cooperating with the positioning groove 18, and the rotation of the adjusting ring 5 can be achieved by providing the adjusting rod 14.

[0023] like Figure 4 As shown, a pressure spring 17 is sleeved on the outer surface of the adjusting rod 14, and the two ends of the pressure spring 17 respectively contact the top of the fixing bolt 15 and the outer surface of the adjusting rod 14. By setting the pressure spring 17, a continuous force can be provided to the fixing bolt 15, so that it can be stably located in the positioning groove 18, thereby improving the stability of the fixing of the adjusting ring 5.

[0024] like Figure 4 As shown, a limiting groove 16 is provided on the outer surface of the adjusting rod 14, and the interior of the fixing bolt 15 is slidably connected to the inner surface of the limiting groove 16. By providing the limiting groove 16, the fixing bolt 15 can be effectively prevented from rotating, thereby improving stability.

[0025] like Figure 2 As shown, the bottom end of the fixing ring 4 is fixedly connected with a mounting ring 12, and the high-temperature felt body 11 is fixedly connected to the bottom end of the fixing ring 4 through the mounting ring 12.

[0028] The utility model provides a high-temperature felt that is easy to disassemble. The specific working principle is as follows:

[0029] When the high-temperature felt body 11 is installed, the adjusting rod 14 is rotated to drive the adjusting ring 5 to rotate, so that the pushing block 6 contacts the driven block 8 during the rotation and pushes the driven block 8 to slide inside the square through hole 7, so that the driven block 8 enters the fixing groove 19 to fix the fixing ring 4, and then loosens the fixing bolt 15. The fixing bolt 15 enters the positioning groove 18 under the action of the thrust of the pressure spring 17 to fix the adjusting ring 5. When disassembling, the staff pulls out the fixing bolt 15 from the positioning groove 18, and then resets the adjusting ring 5, so that the pushing block 6 is separated from the driven block 8. After separation, the driven block 8 is reset and retracted into the square through hole 7 under the action of the reset spring 10. Then the fixing ring 4 is connected to the high-temperature felt body 11 and pulled out from the inside of the outer sleeve 1 for disassembly.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
