[0002] The ventilated waveguide window is a cutoff waveguide bundle composed of many small cutoff waveguides, and its cross-sectional shape is hexagonal. The cross-sectional forms of the ventilated waveguide window are usually the following: circular, square and hexagonal. Since the square and hexagonal waveguides allow less propagation of wave modes than the circular waveguides, they are more beneficial to the isolation of electromagnetic waves. Under the condition of the same insertion attenuation capability, the channel area of ​​the hexagonal waveguide is larger than that of the square waveguide window.

[0003] Ventilation waveguide windows are usually assembled by bolt crimping, but the waveguide windows need to be manually adjusted during assembly so that the mounting holes on the window are aligned with the mounting holes on the wall. However, the waveguide windows are installed at a high position, making manual adjustment difficult and making it impossible to keep the window stable during installation.

[0004] Therefore, there is an urgent need for an improved structure of a fast-assembled anechoic chamber ventilation waveguide window to solve the above-mentioned problems. Utility Model Content

By setting the supporting mechanism 4, the waveguide window form 1 can be automatically and stably supported on the wall. After the waveguide window form 1 is placed on the wall, the staff operates the remote control device to start the multiple electric telescopic rods 5 in the supporting mechanism 4. The electric telescopic rods 5 are started so that their output ends drive the supporting plates 6 to extend, so that the multiple supporting plates 6 are all fitted with the inner wall of the wall. Then, when the assembly holes 3 on the waveguide window form 1 are aligned with the mounting holes on the wall, the extension lengths of the electric telescopic rods 5 are adjusted one by one to drive the assembly holes 3 of the waveguide window form 1 to be aligned with the mounting holes of the wall during adjustment. The installation of the waveguide window form 1 is relatively quick and convenient, and no manual adjustment is required.

[0026] Two fixing blocks 7 are symmetrically installed on the electric telescopic rod 5, and two grooves 8 are symmetrically provided on the fixing block 7. A first spring 9 is fixedly installed inside the groove 8, and a clamping block 10 is fixedly installed at one end of the first spring 9.

Since the clamping block 10 is supported by the first spring 9, the clamping block 10 has a certain contractility. When the electric telescopic rod 5 or the support plate 6 is damaged, the electric telescopic rod 5 can be directly pulled upward to be removed from the waveguide window body 1, thereby facilitating the replacement of the electric telescopic rod 5 and the support plate 6. At the same time, one end of the clamping block 10 is arranged in an arc shape, so that the clamping block 10 is easier to engage with and separate from the clamping slot 11.

Through the arrangement of the fixing plates 13, the second spring 14, the plug rod 15 and the slot 16, one end of the plug rod 15 is inserted into the slot 16 and supported by the second spring 14, so that the filter screen 12 can be fixed to prevent the filter screen 12 from falling off, and the plug rod 15 can be pulled outward to disengage one end of the plug rod 15 from the slot 16, so that the filter screen 12 can be disassembled, and the anti-skid patterns provided on one end of the plug rod 15 can increase the friction force on its surface, so that the plug rod 15 can be pulled more easily.

[0028] In this embodiment, if Figure 1-Figure 5 As shown, the working process of a fast-assembled anechoic chamber ventilation waveguide window structure provided in this embodiment is as follows:

[0029] After the waveguide window body 1 is placed on the wall, the staff operates the remote control device to start the multiple electric telescopic rods 5 in the supporting mechanism 4. The electric telescopic rods 5 are started so that their output ends drive the supporting plates 6 to extend, so that the multiple supporting plates 6 are all fitted with the inner wall of the wall. Then, when the assembly holes 3 on the waveguide window body 1 are aligned with the mounting holes on the wall, the extension lengths of the electric telescopic rods 5 are adjusted one by one to drive the assembly holes 3 of the waveguide window body 1 to be aligned with the mounting holes on the wall. The filter 12 is set to filter the air. One end of the plug rod 15 is inserted into the slot 16 and supported by the second spring 14, which can fix the filter 12 and prevent it from falling off. The plug rod 15 can be pulled outward to disengage one end of it from the slot 16, thereby disassembling the filter 12.

Since the clamping block 10 is supported by the first spring 9, the clamping block 10 has a certain contractility. When the electric telescopic rod 5 or the support plate 6 is damaged, the electric telescopic rod 5 can be directly pulled upward to be removed from the waveguide window form 1, thereby facilitating the replacement of the electric telescopic rod 5 and the support plate 6. At the same time, one end of the clamping block 10 is set The arc shape makes it easier for the card block 10 to engage with and separate from the card slot 11. The filter screen 12 can be filtered by the setting of the fixing plate 13, the second spring 14, the plug rod 15 and the slot 16. One end of the plug rod 15 is inserted into the slot 16 and supported by the second spring 14. The filter screen 12 can be fixed to prevent the filter screen 12 from falling off. The plug rod 15 can be pulled outward to disengage one end of the plug rod 15 from the slot 16, thereby disassembling the filter screen 12. At the same time, anti-slip grooves are provided at one end of the plug rod 15 to increase the friction on its surface, so that the plug rod 15 is easier to pull.
