The air tightness test can effectively detect the sealing performance of the radome and ensure that it can work normally under various environmental conditions. The mold is customized according to the shape of the radome, and the mold is used to assist in completing the normal temperature air tightness test of the radome. In the mold, an airtight cover on the mold is provided with an air nozzle, which is used to connect to the air tightness tester, and then the air tightness tester is used to complete the mold-assisted detection of the sealing of the radome through the air nozzle.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1 、 2And 4, an airtight cover plate for performing a room-temperature airtightness test on a radome mold, comprising an airtight cover plate 1, a first sealing ring 2 being fixed to the airtight cover plate 1, an air nozzle 3 being provided through the airtight cover plate 1 inside the first sealing ring 2, an airtightness detector 6 being sealed and fixed to the air nozzle 3, and the airtightness detector 6 being used in conjunction with the air nozzle 3 to complete the room-temperature airtightness test on the radome mold;

[0020] Sealing components are symmetrically fixed on the air nozzle 3. The two sealing components are respectively arranged on both sides of the airtight cover 1. The sealing components include a circular ring 4, which is fixed on the air nozzle 3. A second sealing ring 5 is coaxially fixed on the circular ring 4. The second sealing ring 5 is embedded and fixed on the airtight cover 1. The two circular rings 4 and the two second sealing rings 5 ​​cooperate with the airtight cover 1 to seal and lock the air nozzle 3 on the airtight cover 1. When the radar cover mold is subjected to a room temperature airtightness test, there is no need to assist in pressing the air nozzle 3. The operation is simple and can ensure the accuracy of the room temperature airtightness test.

[0021] Example 2: In Example 1, the airtight cover plate 1 is used in conjunction with the lower mold in the mold. The setting of the first sealing ring 2 ensures the seal between the airtight cover plate 1 and the lower mold. However, it is necessary to fix the position between the airtight cover plate 1 and the lower mold to avoid the airtight cover plate 1 from separating from the lower mold during the airtightness test at room temperature. Figure 1 、 3 and 4, as another preferred embodiment of the present invention, which differs from embodiment 1 in that an adjustment mechanism is provided on the airtightness tester 6, the adjustment mechanism is provided on the airtight cover plate 1, and the first sealing ring 2 and the adjustment mechanism are respectively provided on both sides of the airtight cover plate 1, and the adjustment mechanism is used to adjust the position of the airtight cover plate 1, so that during the airtightness test at room temperature, the airtight cover plate 1 will not fall off the lower mold due to the restriction on the airtight cover plate 1;

[0022] The adjustment mechanism includes a connecting rod 10, which is a C-shaped structure. The connecting rod 10 is mounted on the air tightness tester 6. The C-shaped connecting rod 10 does not obstruct the air tightness tester 6, thereby ensuring the separation between the airtight cover 1 and the connecting rod 10.

[0023] Two fixing components are symmetrically fixed on the connecting rod 10, and the fixing component includes a fixing rod 9, which is fixed on the connecting rod 10, and an electric telescopic rod 11 is fixed on one of the fixing rods 9, and an electromagnet 8 is fixed on the fixing rod 9. The two electromagnets 8 are connected in series through wires, and the two electromagnets 8 are energized or de-energized synchronously. An iron plate 7 is provided on the electromagnet 8, and the iron plate 7 is fixed on the airtight cover 1. When in use, the electric telescopic rod 11 is fixed at a specified position, and the electric telescopic rod 11 is used to synchronously adjust the height of the two fixing rods 9. When the two electromagnets 8 are energized, the two electromagnets 8 are used to adjust the height of the airtight cover 1 together by adsorption and fixation with the two iron plates 7. When the airtight cover 1 is engaged on the lower mold, the position of the airtight cover 1 is locked on the lower mold, thereby ensuring the sealing between the airtight cover 1 and the lower mold during the normal temperature airtightness test.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
