[0030] Please refer to Figures 1-4 As shown, this embodiment is a fatigue test device for a fire and smoke prevention safety household door, including:

[0031] A test component, which includes a test frame 11 and a mounting plate 14. The mounting plate 14 is fixed on one side of the outer surface of the test frame 11. A limit groove 111 is opened on one side of the outer surface of the test frame 11. A door frame 12 is installed inside the test frame 11, and a door panel 13 is installed on one side of the outer surface of the door frame 12;

[0032] The test frame 11 is the framework of the entire test component, providing the basic structure and support of the test device. It needs to have sufficient strength and stiffness to ensure stability and reliability during long-term repeated fatigue tests. The mounting plate 14 provides a stable mounting platform for the door frame 12.

[0033] An adjustment component, which includes a motor 21, a lead screw 22, a lead screw nut 23, a movable plate 24, a limit block 241, and a connecting block 25. The motor 21 is fixed on the upper surface of the mounting plate 14. The lead screw 22 is fixedly connected to the output end of the motor 21. The lead screw nut 23 is threadedly penetrated on the outer surface of the lead screw 22. The movable plate 24 is fixedly connected to the outer surface of the lead screw nut 23. The limit block 241 is fixedly connected to one side of the outer surface of the movable plate 24. The connecting block 25 is fixed on one side of the outer surface of the movable plate 24;

[0034] The motor 21 is the power source of the entire adjustment component and is fixed on the upper surface of the mounting plate 14. The lead screw nut 23 is threaded through the outer surface of the lead screw 22. When the lead screw 22 rotates, the lead screw nut 23 moves linearly along the direction of the lead screw 22 to adjust the position of the movable plate 24, facilitating the adaptation to different door panels 13.

[0035] One side of the outer surface of the connecting block 25 is rotatably installed with an electric push rod 26. One side of the outer surface of the electric push rod 26 is installed with a first connecting frame 261. The output end of the electric push rod 26 is connected to a second connecting frame 27. One side of the second connecting frame 27 is rotatably installed with an adsorption frame 28. One side of the outer surface of the adsorption frame 28 is installed with a vacuum suction cup 29;

[0036] The vacuum suction cup 29 is connected to the second connecting frame 27 through the adsorption frame 28 and is mainly used to firmly adsorb and fix the door panel 13 to ensure the stability of the door panel 13 and the accuracy of the test during the test, and the vacuum suction cup 29 does not damage the outer surface of the door panel 13.

[0037] Working principle:

[0038] During the fatigue test, the staff starts the motor 21 through an external controller. The motor 21 drives the lead screw 22 to rotate. At this time, the lead screw nut 23 moves vertically up and down on the outer surface of the lead screw 22, and the limit block 241 moves in the limit groove 111 to limit the movable plate 24. At this time, the electric push rod 26 reaches the appropriate position. Then, the staff installs the door frame 12 inside the test frame 11. Then, the staff adsorbs the vacuum suction cup 29 on one side of the outer surface of the door panel 13, and then through the external controller, the controller starts the electric push rod 26 to extend and retract. When the electric push rod 26 extends, it synchronously drives the second connecting frame 27 to move to one side, closing the door panel 13 inside the door frame 12. When the electric push rod 26 shortens, the second connecting frame 27 shortens and synchronously drives the other side of the outer surface of the vacuum suction cup 29 to move, synchronously opening the door panel 13. And the first connecting frame 261 and the second connecting frame 27 rotate during the extension and retraction of the electric push rod 26, and the vacuum suction cup 29 adsorbs at different positions of the door panel 13;

[0039] In this step, through the precise cooperation of the adjustment component, the fatigue test device for fire and smoke prevention safety doors can efficiently and accurately simulate the opening and closing conditions of the door panel 13 during actual use, which not only improves the reliability of the test results but also improves the applicability of the test.

The fixed rod 31 is installed on one side of the outer surface of the test frame 11. The chute 311 is opened in the middle of one side of the outer surface of the fixed rod 31. The fixed plate 32 is fixedly installed on one side inside the chute 311. The first threaded rod 33 is threadedly penetrated through the center of the outer surface of the fixed plate 32.

Through the chute 311, the precise movement of components such as the fixed plate 32 in a specific direction can be ensured. The first threaded rod 33 is threadedly penetrated through the center of the outer surface of the fixed plate 32 and is rotatably connected to the first pressing plate 34. By rotating the first threaded rod 33, the position of the first pressing plate 34 can be adjusted to tightly press on the door panel, thereby realizing the fixation of the door panel 13. The second pressing plate 38 is connected to one side of the outer surface of the second threaded rod 37 and works in cooperation with the first pressing plate 34 to jointly achieve the precise fixation of the door panel 13.

[0044] Working principle:

[0045] When installing the door frame 12, the staff places the door frame 12 into the test frame 11. Then the staff holds the first threaded rod 33 and rotates the first threaded rod 33. The first threaded rod 33 synchronously drives the first pressing plate 34 to press the door frame 12 tightly inside the test frame 11. Then rotate the second threaded rod 37. The second threaded rod 37 drives the second pressing plate 38 to be tightly fixed inside the test frame 11. The door frame 12 is fixedly installed inside the test frame 11, and different door frames 12 can be installed;

[0046] This step can be used for testing door panels of various specifications. The flexibility enables manufacturers and testing institutions to use the same equipment to test various door panels, thereby reducing the dependence on dedicated equipment and also improving the versatility and testing efficiency of the testing device.
