Description

Technical Field

[0001] This utility model relates to the field of aircraft fireproof material testing technology, and in particular to an aircraft fireproof material testing device. Background Technology

[0002] In the research and development and quality testing of aircraft fire-resistant materials, fire resistance testing is a crucial step. Typically, testers install the material under test in a test chamber and simulate a high-temperature flame environment using a burner to evaluate the material's fire resistance, heat insulation, and structural stability under extreme conditions.

[0003] However, in actual testing, because multiple materials need to be tested continuously or the same material needs to be tested repeatedly, the inside of the test chamber is often kept at a high temperature for a long time.

[0004] Currently, common fireproof material testing devices typically require operators to manually open the test chamber door or disassemble parts of the structure when changing test samples in order to put in new test materials or take out old samples. However, when the inside of the test chamber is still in a high-temperature environment, this operation method can easily cause burns to the operators, posing a significant safety hazard. Utility Model Content

[0005] This utility model provides an aircraft fireproof material testing device, including a test chamber. The front of the test chamber is provided with a sealed door, and a side outlet is opened on the side of the test chamber. The side outlet is sealed by a side plate. An electric push rod is installed on the top of the test chamber. The telescopic end of the electric push rod is connected to a sealing assembly, which is connected to the side plate. When the electric push rod extends outward, it drives the sealing assembly to move and pushes the side plate out of the side outlet, thereby opening the side outlet. When the electric push rod retracts inward, the sealing assembly drives the side plate to reset and insert into the side outlet, while applying a clamping force to the side plate to seal and fix the side outlet.

[0006] Preferably, the upper end of the side plate is provided with a long plate, and a sliding groove is opened on the upper side of the long plate, which is slidably connected to the slider at the top of the test box.

[0007] Preferably, a fixing plate is provided on the long plate, and a screw is threadedly connected to one side of the fixing plate, with one end of the screw being rotatably connected to the positioning plate.

[0008] Preferably, the sealing assembly includes a sealing plate, a crossbar is fixedly mounted on the sealing plate, an elastic band is connected to the crossbar, one end of the elastic band is connected to the outer side of the side plate, the sealing plate is a rectangular structure with a hollow center, and the sealing plate seals the connection between the side plate and the side outlet.

[0009] Preferably, the upper end of the sealing plate is hinged to a connecting rod, and the upper end of the connecting rod is hinged to the piston end of the electric push rod.

[0010] Preferably, a sliding rod is fixedly installed at each of the four corners of the sealing plate. The sliding rod slides inside a hollow cylinder set on the outside of the test box, and a spring connects the inner wall of the hollow cylinder to the sliding rod.

[0011] Preferably, the test box has guide rails symmetrically arranged on one side, and the lower side of the sealing plate has sliding holes that are slidably connected to the guide rails.

[0012] Preferably, the test chamber has a groove on its side, and the groove is located at the upper end of the side outlet.

[0013] Preferably, the test chamber has a smoke exhaust port on the rear side.

[0014] Preferably, the test chamber has a base inside, and an adjustment block is rotatably mounted inside the base via a rotating rod. A burner is installed on the adjustment block.

[0015] This utility model provides an aircraft fire-resistant material testing device, which, compared with the prior art, offers the following advantages:

[0016] 1. This utility model achieves automated control of the test chamber's side outlet by setting up an electric push rod to drive the sealing assembly to automatically open and close the side plate. During continuous testing, the interior of the test chamber remains at a high temperature due to high-temperature combustion testing. Traditional devices require testers to manually open the chamber door or disassemble parts to replace test samples, posing a high risk of burns. However, this utility model, through the movement of the electric push rod in conjunction with the sealing assembly and the side plate, allows for rapid replacement of test materials without opening the test chamber door, effectively preventing testers from directly contacting the high-temperature internal environment and significantly improving operational safety and testing efficiency.

[0017] 2. This utility model ensures stable guidance of the side plate during movement by setting a sliding rod, hollow cylinder and spring structure between the sealing component and the test chamber. At the same time, the side plate is connected by an elastic band to achieve flexible buffering and reliable sealing. This structure not only improves the overall sealing performance and service life of the device, but also ensures the smoothness and safety of the operation during frequent opening and closing.

Detailed Implementation

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please refer to Figures 1-8 This utility model provides an aircraft fireproof material testing device, including a test box 1. The front of the test box 1 is provided with an openable and closable sealed door 2 for loading and unloading test samples. The rear of the test box 1 is provided with a smoke exhaust port 22 for discharging the smoke generated during the test and keeping the test environment clean.

[0031] The test chamber 1 is equipped with a base 19 inside. Inside the base 19, an adjustment block 20 is rotatably mounted via a rotating rod. A burner 21 is installed on the adjustment block 20 to simulate a high-temperature flame environment for burning tests on fireproof materials. The angle of the burner 21 can be adjusted via the adjustment block 20 to meet different testing requirements.

[0032] The test chamber 1 has a side outlet 3 on its side for replacing test materials. The side outlet 3 is sealed by a side plate 4 to ensure the airtightness of the test chamber 1 and the stability of the test environment during the test. A long plate 14 is fixedly connected to the upper end of the side plate 4. A sliding groove is provided on the upper side of the long plate 14. The sliding groove slides in cooperation with a slider set at the top of the test chamber 1, so that the side plate 4 remains stable during movement.

[0033] Furthermore, a fixing plate 15 is provided on the long plate 14, and a screw 16 is threadedly connected to one side of the fixing plate 15. One end of the screw 16 is rotatably connected to the positioning plate 17. By rotating the screw 16, the position of the positioning plate 17 can be adjusted, thereby realizing the limiting and guiding function of the side plate 4 during the sliding process and improving the structural stability.

[0034] like Figure 7 As shown, a fixing plate 15 is provided on the long plate 14. A screw 16 is threadedly connected to one side of the fixing plate 15. One end of the screw 16 is rotatably connected to the positioning plate 17. By rotating the screw 16, the position of the positioning plate 17 can be adjusted, thereby fixing the material to be tested.

[0035] like Figure 1 and Figure 2 As shown, an electric push rod 12 is installed on the top of the test box 1. The telescopic end of the electric push rod 12 is hinged to a sealing assembly. The sealing assembly is linked to the side plate 4. The sealing assembly includes a sealing plate 5, which is a rectangular structure with a hollow center. Its upper end is hinged to the piston end of the electric push rod 12 through a connecting rod 9. The sealing plate 5 seals the connection between the side plate 4 and the side outlet 3.

[0036] Slide rods 10 are fixedly installed at the four corners of the sealing plate 5. The slide rods 10 are slidably installed inside the hollow cylinder 11 set on the outside of the test box 1. A spring 13 is connected between the inner wall of the hollow cylinder 11 and the slide rod 10. The spring 13 provides buffering force during the reset process of the sealing assembly, while ensuring the smooth operation and sealing of the sealing assembly.

[0037] A sliding hole 8 is provided on the lower side of the sealing plate 5. The sliding hole 8 slides in cooperation with the guide rail 18 symmetrically arranged on one side of the test box 1 to ensure that the sealing plate 5 has good guidance during movement and avoids displacement that could lead to sealing failure.

[0038] A crossbar 6 is also fixedly installed on the sealing plate 5. An elastic band 7 is connected to the crossbar 6. One end of the elastic band 7 is connected to the outside of the side plate 4. Through the extension and retraction of the electric push rod 12, the sealing assembly can drive the elastic band 7 to pull the side plate 4 to move.

[0039] The specific operation process is as follows:

[0040] When the electric push rod 12 extends outward, the sealing plate 5 moves outward with the connecting rod 9. The sealing plate 5 drives the elastic band 7 to pull the side plate 4, so that the side plate 4 moves out of the side outlet 3, thereby opening the side outlet 3. At the same time, the side plate 4 drives the fixing plate 15 to move out together, which facilitates the replacement of test materials.

[0041] When the electric push rod 12 retracts inward, the sealing plate 5 moves inward, causing the side plate 4 to reset and insert into the side outlet 3. At this time, the upper end of the sealing plate 5 enters the groove on the side of the test chamber 1. The groove is located at the upper end of the side outlet 3, making the sealing plate 5 fit the structure of the test chamber 1 more closely, which can enhance the fixing and sealing effect of the side plate 4. At the same time, the spring 13 and the elastic band 7 work together to apply a pressing force to the side plate 4, ensuring that the sealing connection between it and the test chamber 1 is stable and reliable, and preventing high-temperature flue gas leakage.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
