Figure 3 The fixing sleeve 11 has a rectangular cross section, and is provided with a groove body 111, which penetrates through the outer wall of one side of the fixing sleeve 11 so that the fixing sleeve 11 forms an opening on one side, and a moving block 13 is slidably connected in the groove body 111, and the moving block 13 can move axially along the fixing sleeve 11. The moving block 13 is provided with a groove body 2 131, which penetrates through the outer wall of one side of the moving block 13 so that the moving block 13 forms an opening on one side, and the opening direction is the same as that of the opening of the fixing sleeve 11. An elastic pad 5 is installed in the second groove body 131. The elastic pad 5 is a rubber pad.

The tube body 2 is at least partially inserted into the moving block 13. The tube body 2 is a cylindrical tubular part with an opening at the top. After the tube body 2 is inserted into the second groove body 131 from the opening of the moving block 13 and installed, the elastic pad 5 clamps the two sides of the tube body 2, so that the tube body 2 is fixed to the moving block 13.

The fixed plate 14 is located above the pipe body 2. A driving component 15 is installed on the upper end of the fixed plate 14. The driving component 15 is a cylinder. The output end of the driving component 15 passes downward through the fixed plate 14 and is connected to the moving plate 3. The moving plate 3 is located below the fixed plate 14. The moving plate 3 can move up and down under the drive of the moving component 15.

[0025] like Figure 1 , Figure 2As shown, a plug sleeve 31 is fixedly installed at the bottom of the movable plate 3, and the plug sleeve 31 can be inserted into the tube body 2, and the outer diameter of the plug sleeve 31 is smaller than the tube body 2. An extension platform 312 is provided at the bottom of the plug sleeve 31, and the outer diameter of the extension platform 312 matches the inner diameter of the tube body 2. Through holes 3121 are provided on both sides of the axis of the extension platform 312, and the through holes 3121 pass through the extension platform 312 from top to bottom. A resistor element 21 is provided at the bottom of the inner side of the tube body 2, and wires 22 are connected on both sides of the resistor element 21. The wires 22 are metal wires. After magnesium oxide powder is filled in the tube body 2 and the powder is compacted, the resistor element 21 is fixed to the inner side of the bottom of the tube body 2, and the wires 22 on both sides of the resistor element 21 extend upward from the tube body 2.

[0026] like Figure 1 , Figure 2 As shown, a motor 16 is installed on the upper end of the fixed plate 14, and a screw 4 is connected to the output end of the motor 16. The screw 4 is inserted into the sleeve 31, and a channel portion 313 for the flow of filler is formed between the inner wall of the sleeve 31 and the outer wall of the screw 4. The sleeve 31 is provided with a feed port 311, and the feed port 311 is used to introduce magnesium oxide powder. The feed port 311 is located at the upper part of the sleeve 31, and the feed port 311 is connected to the channel portion 313.

[0027] like Figure 2 As shown, the screw rod 4 includes a second boss 41 located at the bottom, a countersunk hole 3122 is provided at the bottom of the extension platform 312, the bottom of the channel portion 313 is connected to the top of the countersunk hole 3122, the second boss 41 can be inserted into the countersunk hole 3122 to close the bottom of the extension platform 312, the countersunk hole 3122 and the channel portion 313 are coaxially arranged, the aperture of the countersunk hole 3122 is larger than the inner diameter of the channel portion 313, and the aperture of the countersunk hole 3122 matches the outer diameter of the second boss 41.

[0028] like Figure 2 As shown, when the extension platform 312 is at the lower limit position, the second boss 41 is completely inserted into the counterbore 3122 , the upper bottom surface of the counterbore 3122 abuts against the upper end surface of the second boss 41 , and the lower end surface of the second boss 41 is flush with the lower end surface of the extension platform 312 .

[0029] like Figure 4 As shown, when the insert sleeve 31 moves upward and makes the extension platform 312 at the upper limit position, the countersunk hole 3122 and the boss 2 41 are separated up and down, so that the bottom of the extension platform 312 is opened, and the magnesium oxide powder introduced from the feed port 311 passes through the channel portion 313 and the countersunk hole 3122 into the tube body 2. In addition, due to the setting of the screw 4, when the magnesium oxide powder is transported downward along the outer periphery of the screw 4, the screw 4 plays a role in pushing the magnesium oxide powder to flow downward, so as to increase the feeding rate.

[0030] The specific usage is:

[0031] ①Install pipe body main body 2:

[0032] A resistor element 21 is placed at the bottom of the tube body 2 , and wires 22 on both sides of the resistor element 21 extend upward and hang on the upper end of the tube body 2 .

[0033] The output end of the driving component 12 retracts downward and drives the moving block 13 to move downward, so that the moving block 13 is at the lower limit position, and the elastic pad 5 is inserted into the tube body 2. At this time, the tube body 2 is located below the plug sleeve 31 and the screw rod 4.

[0034] Pass the two conducting wires 22 through the through holes 3121 on both sides respectively.

[0035] The output end of the driving component 12 moves upward to insert the extension platform 312 into the tube body 2. After the extension platform 312 is inserted, the distance between the extension platform 312 and the bottom of the tube body 2 is about two-fifths of the overall height of the tube body 2. At this time, the boss 2 41 is inserted into the countersunk hole 3122, and the bottom of the extension platform 312 is closed.

[0036] ②Feeding:

[0037] like Figure 4 As shown, the extension platform 312 moves upward to separate the boss 2 41 from the counterbore 3122 , the screw 4 rotates under the action of the motor 16 , the feed is fed at the feed port 311 , and the magnesium oxide powder raw material enters the tube body 2 from the channel portion 313 .

[0038] ③Compaction:

[0039] The extension platform 312 moves downward to allow the second boss 41 to be inserted into the counterbore 3122 , and the bottom of the extension platform 312 is closed, and the feeding is terminated. At this time, the lower end surface of the second boss 41 is flush with the lower end surface of the extension platform 312 .

[0040] The driving component 12 drives the moving block 13 to move upward, so that the tube body 2 rises, so that the lower end surface of the boss 2 41 and the lower end surface of the extension platform 312 cooperate with the inner wall of the tube body 2 to compact the magnesium oxide powder in the tube body 2.

[0041] like Figure 5 As shown, after completing a compaction operation, the moving block 13 moves downward so that the distance between the extension platform 312 and the bottom of the tube body 2 is about four-fifths of the overall height of the tube body 2, and then the above-mentioned operations ②③ are performed.

[0042] By feeding and compacting the magnesium oxide powder layer by layer, the distance between the magnesium oxide powders is reduced, the compaction effect is better, and it is not easy to loosen. In addition, when the pipe body 2 is in use, the external temperature is transmitted to the resistor element 21 through the pipe wall of the pipe body 2 and the magnesium oxide powder. The tighter magnesium oxide powder filling is beneficial to the temperature conduction rate and improves the temperature detection response time.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
