To ensure the performance stability of these devices in practical applications, rigorous testing of waveguide circulators is essential. This is especially critical in high-power, high-frequency operating environments. The covered waveguide dual-path circulator features a 2+0 structure with waveguide ring branch modules, used in multi-channel transmission and shared transmit / receive antenna systems. Due to the structural characteristics of waveguide devices, auxiliary test components must be frequently disassembled for operator use during testing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-2 As shown, a universal pneumatic testing fixture for a waveguide dual-path circulator with a cover includes a base plate 1, the top of which has a groove.

[0025] The top of the base plate 1 is provided with a block fixing plate 4 and a baffle 2 on both sides of the groove. The baffle 2 and the block fixing plate 4 are provided with an air tightness measuring block 5 on the opposite side. The top left and right sides of the base plate 1 are provided with a quick clamp base 6 at the front and rear. The quick clamp base 6 is provided with a vertical quick clamp 10. The top of the base plate 1 is provided with a cylinder fixing base 3. The top of the cylinder fixing base 3 is fixedly installed with a double rod cylinder 9 by a screw. The block fixing plate 4 is fixedly installed with the right end of the double rod cylinder 9 by a screw. The double rod cylinder 9 is provided with a hand lever valve 8. The baffle 2, the cylinder fixing base 3 and the quick clamp base 6 are all fixedly installed with the base plate 1 by a screw.

[0026] An airtightness test cover 7 is provided above the groove at the top of the base plate 1. A quick-connect air pipe connector 12 is fixedly installed at the front top of the airtightness test cover 7. A boss and a sealing ring are provided at the bottom of the airtightness test cover 7. During operation, the base plate 1 is first placed on a flat ground to ensure the stability of the testing fixture. After the testing fixture is stable, the product to be tested is placed in the groove at the top of the base plate 1. Then, the lever valve 8 is moved back and forth to ensure that the double-rod cylinder 9 is in the guide rod retracted state. Next, the lever valve 8 is moved to extend the double-rod cylinder 9. After the double-rod cylinder 9 extends, it drives the block fixing plate 4 to move, and the airtightness test blocks 5 on the left and right sides are pressed against the product. The product is then placed on the airtightness test cover plate 7, and the vertical quick clamp 10 is moved in a crisscross motion to press the product. After the product is positioned and clamped securely, the airtightness test can begin. This makes the test fixture easy to use. Therefore, this utility model uses a semi-automatic fixture-assisted testing scheme, which uses a double-rod cylinder 9 and a vertical quick clamp 10 to seal the four waveguide ports on two sides and the cover surface for airtightness testing. By replacing a small part of the fixture, it can be used for products of different frequency bands, saving material and labor costs. At the same time, it can improve product testing efficiency and product pass consistency, enhance product stability, and reduce the test failure rate.

[0027] The vertical quick clamp 10 includes a connecting plate 103 bolted to a quick clamp base 6. A wrench 101 is rotatably mounted on the connecting plate 103, and a rotating block 102 is fixedly mounted on the wrench 101. A connecting rod 104 is rotatably mounted between the rotating block 102 and the connecting plate 103. A threaded clamping rod 105 passes through the upper part of the connecting rod 104. Fixing bolts 107 are threadedly connected to the outer surface of the threaded clamping rod 105 on both the left and right sides of the connecting rod 104. A clamping block 106 is fixedly connected to one end of the threaded clamping rod 105. During operation, when the airtightness test cover 7 is placed on top of the product to be tested, it can be clamped and positioned by the vertical quick clamp 10. When using the vertical quick clamp 10, first turn the wrench 101 so that the wrench 101 drives the rotating block 102 and the connecting rod 104 to rotate on the connecting plate 103. Then, the rotation of the connecting rod 104 can drive the threaded clamp rod 105 and the clamping block 106 to rotate. The clamping block 106 rotates to the top of the airtightness test cover 7 to squeeze and clamp it. At the same time, the fixing bolt 107 facilitates the disassembly and installation of the threaded clamp rod 105 and the connecting rod 104.

[0028] The base plate 1, baffle 2, cylinder fixing base 3, block fixing plate 4, quick clamp base 6, and airtightness measuring cover plate 7 are all made of lightweight and oxidation-resistant aluminum material; during operation, the base plate 1, baffle 2, cylinder fixing base 3, block fixing plate 4, quick clamp base 6, and airtightness measuring cover plate 7 are relatively lightweight and have good oxidation resistance.

[0029] The baffle 2 and the blocking block fixing plate 4 are both provided with mounting grooves on opposite sides. The air tightness measuring blocking block 5 is magnetically connected to the inside of the mounting groove by a magnet. During operation, the air tightness measuring blocking block 5 can be easily disassembled and installed by magnetic attraction.

[0030] The air tightness measuring plug 5 is made of copper. A sealing ring groove is provided on the side of the air tightness measuring plug 5, and a second sealing ring is provided inside the sealing ring groove. During operation, the second sealing ring can make the air tightness measuring plug 5 have a better sealing effect during testing, and the copper material is not easy to damage the product to be tested. At the same time, different second sealing rings can be matched and replaced according to the waveguide port size of different frequency bands.

[0031] Handles 11 are fixedly installed at the top center of the airtight cover plate 7 and the left and right sides of the top of the base plate 1 by four screws; during operation, the handles 11 facilitate the taking and placing of the airtight cover plate 7, and facilitate the lifting and moving of the base plate 1.

[0032] Example 2

[0033] Please see Figure 3-4 As shown in the comparative embodiment one, as another implementation of this utility model, an L-shaped limiting plate 13 is fixedly connected to the outer surface of the connecting rod 104, and the other end of the threaded clamping rod 105 is in contact with the outer surface of the L-shaped limiting plate 13. During operation, the L-shaped limiting plate 13 limits the position of the threaded clamping rod 105, and ensures that the four threaded clamping rods 105 and the clamping block 106 can be kept at the same height during installation, and the four clamping blocks 106 can be at the same height when clamping, thereby facilitating the quick installation of the four threaded clamping rods 105 and the clamping block 106, and meeting the installation requirements.
