[0021] Reference Figure 1-5 A testing device for the frost resistance of building materials includes a testing box 1.

A closing block 4 is fixedly installed on one side of the sealing door 2, and a closing base 5 is fixedly installed on one side of the testing box 1. A limit groove is opened on one side of the closing base 5, and the closing block 4 is adapted to the limit groove. Two closing sliders 6 are slidably installed on the inner side of the limit groove, and closing springs 7 are fixedly installed on the inner walls of both sides of the limit groove. One end of each of the two closing springs 7 is connected to one side of the corresponding closing slider 6.

[0022] In this embodiment, a hot air blower 10 is fixedly installed on the top of the test box 1, a cold air blower 9 is fixedly installed on the bottom of the test box 1, and a protective net 8 is fixedly installed on the inner side of the test box 1 to protect the cold air blower 9 and prevent debris from building materials 11 from damaging the cold air blower 9.

[0023] In this embodiment, a flip base 12 is rotatably installed on both inner walls of the test box 1. Two extrusion sliders 13 are slidably installed on the inner side of each flip base 12. A clamp 15 is fixedly installed on one side of each of the multiple extrusion sliders 13. An anti-slip pad 16 is fixedly installed on one side of each of the multiple clamps 15. Each of the multiple clamps 15 clamps the same building material 11 on one side, which facilitates clamping and limiting the building material 11.

[0024] In this embodiment, extrusion metal blocks 17 are slidably installed on the inner sides of the two flip bases 12, and linkage grooves 14 are opened on one side of the multiple extrusion sliders 13. Linkage metal strips 18 are fixedly installed on both sides of the two extrusion metal blocks 17, and the multiple linkage metal strips 18 are respectively adapted to the corresponding linkage grooves 14.

[0025] In this embodiment, traction metal blocks 25 are fixedly installed on both sides of the plurality of extrusion sliders 13, and corresponding traction springs 28 are fixedly installed on one side of the plurality of traction metal blocks 25.

[0026] In this embodiment, a fixing post 19 is fixedly installed on one side of each of the two flip bases 12. A fixing ratchet 24 is fixedly sleeved on each of the two fixing posts 19. A limiting ratchet 23 is slidably sleeved on each of the two fixing posts 19. The two limiting ratchet 23 are respectively adapted to the corresponding fixing ratchet 24. An eccentric block 21 is slidably sleeved on each of the two fixing posts 19. One side of each of the two eccentric blocks 21 is connected to the corresponding limiting ratchet 23. A rotating disk 22 is fixedly installed on one side of each of the two eccentric blocks 21. A return spring 20 is sleeved on each of the two fixing posts 19. One end of each of the two return springs 20 is connected to the corresponding eccentric block 21.

[0027] In this embodiment, a protective shell 27 is fixedly installed on one side of the detection box 1, and a rotary servo motor 26 is fixedly installed on the inner side of the protective shell 27. One side of the right flip base 12 of the two flip bases 12 is connected to the output shaft of the rotary servo motor 26, so that the rotary servo motor 26 can drive the corresponding flip base 12 to rotate.

[0028] Working principle: During testing, the operator places the building material 11 on two clamps 15 located on the bottom side. Then, the operator manually rotates two rotating discs 22. The rotation of the two discs 22 causes the corresponding eccentric blocks 21 to rotate, releasing the pressure on the corresponding extrusion metal blocks 17. At this time, the two extrusion metal blocks 17 are no longer under pressure. The two extrusion sliders 13 corresponding to the two extrusion metal blocks 17 are affected by the corresponding traction springs 28. The two extrusion sliders 13 on the same flip base 12 move closer together, causing the corresponding clamps 15 to move closer together to clamp the building material 11. After the two clamping mechanisms clamp the building material 11, the operator closes the clamps. The sealing door 2 is closed, and the closing block 4 on one side of the sealing door 2 is inserted into the closing base 5. The two closing sliders 6 are affected by the rebound force of the corresponding closing springs 7, and squeeze and limit the same closing block 4. Then, the staff starts the rotating servo motor 26 through the control panel. The rotating servo motor 26 drives the corresponding flip base 12 to rotate. Since both flip bases 12 are rotatably installed on the inner wall of the test box 1, the rotation of a single flip base 12 drives the building material 11 to rotate, which can drive the other flip base 12 to rotate. At this time, the cold air blower 9 or the hot air blower 10 can be started through the control panel. The cold air blower 9 or the hot air blower 10 are started alternately to carry out the freeze-thaw cycle test.

[0029] The technological advancements of this invention compared to existing technologies are as follows: the mechanism allows the building material 11 to be flipped during testing, ensuring that its surface is evenly exposed to cold air, thus increasing the device's practicality. Furthermore, the use of a freeze-thaw cycle test simulates the freeze-thaw cycle in the natural environment, increasing the accuracy of the test and making it more closely reflect real-world conditions.
