[0002] As modern buildings have increasingly stringent fire safety requirements, fire doors and windows, as important passive fire protection facilities in buildings, play a role in fires that cannot be underestimated. Good sealing performance is the key to ensuring that fire doors and windows can effectively prevent the spread of fire and isolate smoke and harmful gases. It is crucial to ensure the safety of personnel evacuation and reduce fire losses. Relevant fire regulations and standards at home and abroad (such as China's GB 12955 "Fire Door" standard, Europe's EN standard, etc.) have put forward clear requirements for the fire resistance limit, thermal insulation performance and sealing performance of fire doors and windows. These standards have promoted the development of fire door and window sealing detection technology to ensure that products meet safety specifications.

[0003] A Chinese patent with authorization announcement number CN112304505A discloses a sealing test device for detecting fireproof doors and windows, including a connecting mechanism, a base, a flow conversion mechanism for importing and exporting smoke, and a universal wheel. The connecting mechanism is located above the base, the flow conversion mechanism is arranged on the inner side of the base, and the universal wheel is installed at the bottom of the base. It also includes a fixing mechanism and a detection mechanism. The fixing mechanism includes an isolation cover, a fixing rod, a fixing seat, and a leather cup. The fixing rod is arranged at the center of the isolation cover, and the fixing seat is installed at the end of the fixing rod. During actual use of the device, the isolation cover cannot completely seal the fireproof doors and windows when sealing the doors and windows, and the contact between the door panel and the isolation cover cannot be completely sealed, so that the detection result may be affected, resulting in a slight deviation between the detection result and the actual detection result. Utility Model Content

[0004] In view of this, the utility model provides a sealing test device for fireproof doors and windows, which can not only provide a closed testing environment for door panel testing through a sealing box to improve the accuracy of the test, but also make it possible to pull the tested door panel out of the sealing box through a sample vehicle, thereby reducing the time for changing samples and improving the test efficiency, but also can drive the motor to drive the bidirectional screw rod to clamp the tested sample so as to test the sample.

[0005] In order to solve the above technical problems, the utility model provides a sealing test device for detecting fireproof doors and windows, including a smoke making machine, a smoke inlet channel is provided on the smoke making machine, a diffusion port is provided on the smoke inlet channel, and a detection device for testing the sealing of fireproof doors and windows is connected to the diffusion port.

[0006] Through the above technical scheme, when the sealing of doors and windows is tested, the sealing box is a closed environment for the door and window bodies, and accurate test results are obtained in sequence. At the same time, the first expansion frame and the second expansion frame arranged inside the sealing box provide installation positions for the first induced draft fan and the second induced draft fan, and the first induced draft fan and the second induced draft fan are arranged in staggered positions up and down to guide the smoke in the sealing box, so that the smoke circulates in the sealing box and flows around the doors and windows.

[0007] The sealing door panel is arranged on the front side base surface of the sealing box through hinges, the first expansion frame is arranged on the inner top wall of the sealing box, and the first exhaust fans are arranged in sequence on the lower base surface of the first expansion frame.

[0008] Through the above technical solution, the sealed door panel seals the sealed box, so that when the smoke making machine provides smoke into the sealed box, the smoke is prevented from flowing out of the sealed box from the gap or the unclosed box body. The first induced draft fan is installed through the first expansion frame, so that the smoke at the top of the sealed box flows downward through the first induced draft fan.

[0009] The second expansion frame is arranged on the upper part of the bottom plate of the sealing box, and the second induced draft fans are arranged in sequence on the upper base surface of the second expansion frame.

[0014] Through the above technical solution, the function of the through hole is to prevent the closed sample car from flowing toward the surface of the sample when the first and second induced draft fans guide the smoke. By arranging a slide groove and a drive motor on the sample car, a device that can clamp doors and windows is obtained.

[0015] One end of the bidirectional lead screw is arranged at the output end of the driving motor, and the other end passes through the side base surface of the slide groove and is connected to the inner wall of the slide groove. The slider is slidably arranged in the slide groove through the bidirectional lead screw. The side base surfaces on both sides of the support beam are connected to the side base surfaces of the slider, and the fixed suction cups are arranged in sequence on the side base surfaces of the support beam.

[0016] Through the above technical scheme, by connecting one end of the bidirectional screw rod to the driving motor, the driving motor drives the bidirectional screw rod to rotate, and one end is arranged inside the slide groove, so that the bidirectional screw rod drives the slider to slide in the slide groove, so that the support beams on the two sliders are close to each other. When they are close to each other, the fixed suction cups on the support beams fix the doors and windows, so that the doors and windows are placed vertically on the model car.

[0017] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0018] 1. When the utility model is used, the support beam and the fixed suction cup can be used to quickly replace the door and window samples through the slide groove and the slider on the sample vehicle, so that the detection efficiency is improved.

[0019] 2. When the utility model is used, the smoke generated by the smoke making machine is guided in the sealed box by the first induced draft fan and the second induced draft fan on the first expansion frame and the second expansion frame, so that the smoke circulates in the sealed box and flows around the doors and windows, which is convenient for all-round detection of the doors and windows.

[0020] 3. When the utility model is used, the sample cart can be pushed into and pulled out of the sealing box by the handle. On the one hand, it is possible to better observe whether the sample has a poor sealing problem, and on the other hand, the sample can be quickly replaced. BRIEF DESCRIPTION OF THE DRAWINGS
