[0025] The fire resistance performance testing device for fire doors involved in this technical solution is formed by assembling the upright frame 1, the cross bar 2, the upright pole 3 and the fixed frame 5. The cross bar 2 can be used to connect two sets of upright frames 1, and the fixed frame 5 is welded to the side surfaces of the upright frame 1 and the upright pole 3 respectively, so that the protective door can be fixed between the two fixed frames 5.

[0026] Preferably, the fixing frame 5 and the guide rail 7 are an integrated structure, and the sliding sleeve 8 and the guide rail 7 are in sliding connection.

[0027] During specific use, the sleeve 8 can slide longitudinally along the surface of the guide rail 7 when subjected to tension. The longitudinal sliding of the sleeve 8 can drive the side panel 9 to move longitudinally, so that the expected connected threaded tube 10, the first threaded rod 11 and the fixed block 12 can be adjusted to move longitudinally, which can facilitate the positioning of fire doors of different heights, thereby improving the applicability of the device.

[0028] Preferably, the first threaded rod 11 and the threaded tube 10 are threadedly connected.

[0029] During specific use, the first threaded rod 11 can move laterally when rotating inside the threaded tube 10. The lateral movement of the first threaded rod 11 can drive the fixing block 12 to move laterally. When the first threaded rod 11 drives the fixing block 12 to move to the surface of the fire door, the fire door can be positioned by squeezing the fixing block 12, thereby fixing the fire door.

[0030] Preferably: both ends of the vertical pole 3 are connected to a slide 4, the slide 4 is sleeved on the surface of the cross bar 2, the side surface of the vertical frame 1 is installed with a drive motor 13, the output end of the drive motor 13 is connected to a second threaded rod 14, a bearing seat 15 is installed between the second threaded rod 14 and the other vertical frame 1, the side surface of the vertical pole 3 is connected with a drive block 16, and the second threaded rod 14 runs through the interior of the drive block 16.

When the driving motor 13 is running, it can drive the first threaded rod 11 to rotate inside the bearing seat 15. When the first threaded rod 11 rotates, it can generate a force on the driving block 16 through the threaded connection relationship. When the driving block 16 is subjected to the force, it can generate a force on the vertical rod 3. When the vertical rod 3 is subjected to the force, it can drive the slide 4 to slide on the surface of the cross bar 2. At the same time, the vertical rod 3 can move laterally with the sliding of the slide 4, so that the position of the vertical rod 3 can be adjusted, and when the vertical rod 3 moves, it can drive its side surface fixing frame 5 to move laterally, so that the distance between the two fixing frames 5 can be adjusted, so that the device can adapt to fire doors of different widths and fix them;

[0036] Then place the fire door on the upper surface of the mounting plate 6, and then pull the sleeve 8 upward. The sleeve 8 can slide on the surface of the guide rail 7 under the tension, and the upward sliding of the sleeve 8 can drive the side panel 9 to move upward, and then the first threaded rod 11 can be rotated. When the first threaded rod 11 rotates inside the threaded tube 10, it can move laterally through the threaded connection relationship. The lateral movement of the first threaded rod 11 can drive the fixed block 12 to move laterally. The fixed block 12 moves laterally to the surface of the fire door to squeeze it, and then the remaining positioning mechanisms can be used to fix the fire door in turn, so that the fire door can be quickly fixed. After the fire door is fixed, flame and high temperature simulation can be carried out by a testing mechanism, so that fire resistance test can be carried out by flame and high temperature. By installing a sensor on the fire door, it can be used to test the temperature change of the fire door under flame and high temperature, and the combustion process and burning time of the fire door can be observed.

[0037] The design of this device fully considers ease of use and applicability, allowing operators to quickly secure fire doors as needed, greatly improving work efficiency.
