Slide grooves 6 are provided through both ends of the guide rod 4. A screw hole 7 is provided through the center of the lower end of the guide rod 4. A stud 8 is threaded into the screw hole 7. A push block 9 is fixed to the upper end of the stud 8. Two symmetrical sliders 11 are slidably arranged on the inner wall of the slide grooves 6. The upper part of the sliders 11... A threaded hole 12 is provided through the center of the end, and a bolt 13 is installed in the threaded hole 12. The lower end of the bolt 13 fits against the lower inner wall of the slide groove 6. The upper end of the slider 11 is fixedly connected to a symmetrical slide rod 14. A sleeve 16 is fitted on the outer wall of the slide rod 14. A threaded hole 18 is provided through the upper end of the sleeve 16, and a bolt 19 is installed in the threaded hole 18. The lower end of the bolt 19 fits against the upper end of the slide rod 14. A clamp 5 is fixedly connected to the end of the sleeve 16 on the left and right sides that are close to each other.

[0023] By moving slider 11 left and right along the inner wall of slide groove 6, the distance between sliders 11 can be adjusted. Bolt 13 can fix slider 11. By moving sleeve 16 back and forth along slide rod 14, the distance and relative position of sleeve 16 can be adjusted. Rotating bolt 19 can fix the position of sleeve 16, thereby adjusting the distance between clamps 5, clamping the four corners of the cotton-padded garment, avoiding compression of the cotton-padded garment and resulting in compression of the thickness of the cotton-padded garment. Rotating stud 8 can drive push block 9 to move up and down, which can make the cotton-padded garment bulge. By adjusting the position of clamp 5 and the height of push block 9, the bulge of the cotton-padded garment can be better simulated, reducing measurement errors.

[0024] Please see Figures 2-6In this embodiment, a temperature control device 21 is fixedly connected to the inner edge of the rear end of the constant temperature chamber 1, a data acquisition device 20 is fixedly connected to the front end of the constant temperature chamber 1, and a lid 2 is hinged to the upper opening of the constant temperature chamber 1. In use, the temperature control device 21 can simulate the external environment, the data acquisition device 20 can collect the measured data, and the lid 2 can ensure the sealing of the constant temperature chamber 1. A radiation device 17 is fixedly connected to the lower end of the lid 2, and a sealing ring is fixedly connected to the contact point between the lid 2 and the constant temperature chamber 1. An annular guide rail 3 is fixedly connected to the lower inner wall of the constant temperature chamber 1. In use, the radiation device 17 can simulate the thermal radiation of cotton clothing, and the sealing ring can further improve the sealing of the constant temperature chamber 1.

[0025] Please see Figures 6-7 In this embodiment, the outer wall of the annular guide rail 3 is provided with a limiting groove 15 that surrounds the annular guide rail 3. The upper end of the annular guide rail 3 is provided with a movable plate 22. In use, the movement of the movable plate 22 can be limited by the limiting groove 15, and the stability of the movement of the movable plate 22 can be improved. The end of the movable plate 22 away from the annular guide rail 3 is fixedly connected to a support plate 24. The upper end of the support plate 24 and the lower end of the movable plate 22 are rotatably mounted with a drive wheel 26. The outer wall of the drive wheel 26 is in contact with the inner wall of the limiting groove 15. In use, the drive wheel 26 can rub against the limiting groove 15 to drive the movable plate 22 to move along the annular guide rail 3.

[0026] Please see Figure 7 In this embodiment, a motor 25 and a sensor 27 are installed on the upper end of the movable plate 22. The output end of the motor 25 passes through the upper end of the movable plate 22 and is connected to the shaft of the drive wheel 26. In use, the sensor 27 can collect thermal radiation data, and the motor 25 can drive the drive wheel 26 to rotate, thereby driving the sensor 27 to move at the lower end of the cotton garment, improving the accuracy of the measurement. A limit wheel 23 is rotatably installed at the lower edge of the movable plate 22. The outer wall of the limit wheel 23 is in contact with the inner wall of the annular guide rail 3. In use, the limit wheel 23 slides in contact with the annular guide rail 3, which can further improve the stability of the movable plate 22 when it moves.

[0027] During operation, firstly, according to the size of the cotton-padded garment, move slider 11 left and right along the slide groove 6 to adjust the spacing of slider 11. Then, turn bolt 13 to fix slider 11. Next, move sleeve 16 to adjust the spacing and relative position of the four sleeves 16. Then, turn bolt 2 19 to fix sleeve 16. Then, place the cotton-padded garment on the upper end of guide rod 4. Use clamps 5 to clamp the four corners of the cotton-padded garment. Finally, fine-tune slider 11 and sleeve 16 to ensure the cotton-padded garment is fixed. Then, rotate the stud 8 to make the push block 9 contact the lower end of the cotton-padded garment, causing the garment to bulge. Then, close the box cover 2, start the temperature control device 21 to adjust the temperature, and start the acquisition device 20 and the motor 25. The output end of the motor 25 drives the drive wheel 26 to rotate. After the movable plate 22 drives the sensor 27 to rotate along the annular guide rail 3, start the radiation device 17. Finally, wait for the radiation device 17 to radiate the cotton-padded garment. After the acquisition device 20 collects and analyzes the radiation, the measurement of the cotton-padded garment can be completed.

[0028] Through the above steps, the slider 11 can be moved left and right along the inner wall of the slide groove 6 to adjust the distance between the sliders 11. Bolt 13 can fix the slider 11. The sleeve 16 can be moved back and forth along the slide rod 14 to adjust the distance and relative position of the sleeve 16. The position of the sleeve 16 can be fixed by rotating bolt 19, thereby adjusting the distance between the clamps 5 and clamping the four corners of the cotton-padded garment to avoid compressing the cotton-padded garment and causing the thickness of the cotton-padded garment to be compressed. Rotating the stud 8 can drive the push block 9 to move up and down, which can make the cotton-padded garment bulge. This solves the problem that the clamps may compress the cotton-padded garment when the cotton-padded garment heat reflection test device is used, and it is difficult to simulate the bulge of the cotton-padded garment.
