Description

Technical Field

[0001] This utility model relates to the field of sealing test technology, specifically to an inflation mechanism for testing the sealing performance of a satellite communication antenna. Background Technology

[0002] In the manufacturing process of satellite communication antennas, in order to ensure the airtightness of the satellite communication antennas, it is usually necessary to conduct an airtightness test. During the airtightness test, the satellite communication antenna is placed in a sealed component for testing, and gas is injected into the sealed component through an inflation mechanism. The change in air pressure is detected to determine whether the satellite communication antenna is airtight.

[0003] Existing gas filling mechanisms for testing the sealing performance of satellite communication antennas inject gas into the seal through a gas tube. In the existing technology, the gas tube is generally connected to the seal by a thread. However, under long-term and high-pressure use, the thread sealing effect between the gas tube and the seal will deteriorate, affecting the accuracy of the sealing performance test. At the same time, relative rotation will occur between the gas tube and the seal, which will further affect the sealing effect. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 3 As shown in this embodiment, an inflation mechanism for testing the sealing performance of a satellite communication antenna includes a sealing test component 1. A connecting pipe 2 is installed on the sealing test component 1, and an air pipe 3 is fixedly installed at one end of the connecting pipe 2. A protruding ring 4 is integrally provided at the end of the connecting pipe 2 away from the air pipe 3. The protruding ring 4 is disposed inside the sealing test component 1. A sealing rubber gasket 5 is sleeved on the outer side of the end of the connecting pipe 2 away from the air pipe 3. The protruding ring 4 and the sealing rubber gasket 5 are pressed together. Positioning holes 6 are symmetrically opened on the outer side of the end of the connecting pipe 2 away from the protruding ring 4. A positioning rod 7 is installed on the sealing test component 1 at the position corresponding to the positioning hole 6. The positioning rod 7 is slidably inserted into the positioning hole 6. The sealing rubber gasket 5 is placed on the outside of the connecting pipe 2 near the convex ring 4. The connecting pipe 2 passes through the sealing test piece 1 from the inside to the outside. The convex ring 4 is controlled to squeeze the sealing rubber gasket 5. The sealing rubber gasket 5 squeezes the hole on the sealing test piece 1 and the outside of the connecting pipe 2 to seal the connecting pipe 2 and the hole on the sealing test piece 1. At this time, the positioning rod 7 corresponds to the position of the positioning hole 6, and the positioning rod 7 is moved. The end of the positioning rod 7 is inserted into the positioning hole 6 to fix the position of the connecting pipe 2, prevent the connecting pipe 2 from rotating, and improve the sealing effect of the connecting pipe 2.

[0022] like Figures 1 to 3 As shown, the sealing test piece 1 has a first external thread 8 at the position corresponding to the connecting pipe 2, and the connecting pipe 2 has a first internal thread 9. The first external thread 8 and the first internal thread 9 are threaded together, and a sealant is provided between the first external thread 8 and the first internal thread 9. A nut 10 is threadedly installed on the connecting pipe 2 at the position corresponding to the first internal thread 9.

[0023] The connecting tube 2 is passed from inside the sealing test piece 1 to the outside of the sealing test piece 1. During this process, the first internal thread 9 on the connecting tube 2 is threadedly connected to the first external thread 8 on the sealing test piece 1. The control ring 4 is squeezed against the sealing rubber gasket 5. The nut 10 is threadedly installed on the outside of the connecting tube 2 at the outer position of the sealing test piece 1. The position of the connecting tube 2 is fixed and the nut 10 is rotated. The connection between the first internal thread 9 on the connecting tube 2 and the nut 10 will cause one side of the nut 10 to squeeze the outside of the sealing test piece 1, which is used to fix the position of the connecting tube 2.

[0024] like Figures 1 to 3 As shown, the convex ring 4 has a compression receiving groove 11 at one end near the sealing test piece 1, and the sealing rubber gasket 5 is located inside the compression receiving groove 11.

[0025] When the convex ring 4 compresses the sealing rubber gasket 5, the sealing rubber gasket 5 will be controlled inside the compression receiving groove 11, which can limit the position of the sealing rubber gasket 5 and further improve the compression sealing effect of the sealing rubber gasket 5 on the hole at the first external thread 8 on the compression sealing test piece 1 and the outside of the connecting pipe 2.

[0026] like Figures 1 to 3 As shown, the convex ring 4 has an angled section 12 at one end near the sealing test piece 1.

[0027] The angled design 12 allows the sealing rubber gasket 5 to slide into the inside of the compression storage groove 11.

[0028] like Figures 1 to 3 As shown, a fixing block 13 is symmetrically fixed on one side of the sealing test piece 1, corresponding to the outer position of the connecting pipe 2. A second external thread 14 is provided in the middle of the fixing block 13, and a second internal thread 15 is provided on the positioning rod 7. The second external thread 14 and the second internal thread 15 are threadedly engaged.

[0029] Rotating the positioning rod 7 will cause the positioning rod 7 to move through the connection between the second external thread 14 on the fixing block 13 and the second internal thread 15 on the positioning rod 7, thereby causing the end of the positioning rod 7 to be inserted into the positioning hole 6.

[0030] like Figures 1 to 3 As shown, the end of the positioning rod 7 is chamfered 16.

[0031] It allows for easy control of the end of the positioning rod 7 being inserted into the positioning hole 6.

[0032] This utility model provides an inflation mechanism for testing the sealing performance of satellite communication antennas, and its specific working principle is as follows:

[0033] In use, the sealing rubber gasket 5 is placed on the outside of the connecting pipe 2 near the convex ring 4. The connecting pipe 2 is then passed from inside to outside the sealing test piece 1. During this process, the first internal thread 9 on the connecting pipe 2 is threadedly connected to the first external thread 8 on the sealing test piece 1. The convex ring 4 is controlled to compress the sealing rubber gasket 5, which in turn compresses the hole at the first external thread 8 on the sealing test piece 1 and the outside of the connecting pipe 2, thus sealing the hole between the connecting pipe 2 and the sealing test piece 1. The nut 10 is then threaded onto the outside of the connecting pipe 2 at the position outside the sealing test piece 1, fixing the position of the connecting pipe 2 and controlling the rotation of the nut 10. The corresponding thread on the connecting pipe 2... The connection between the first internal thread 9 and the nut 10 will cause one side of the nut 10 to press against the outside of the sealing test piece 1, which is used to fix the position of the connecting pipe 2. At this time, the positioning rod 7 corresponds to the position of the positioning hole 6. Rotating the positioning rod 7 will cause the positioning rod 7 to move through the connection between the second external thread 14 on the fixing block 13 and the second internal thread 15 on the positioning rod 7, which will cause the end of the positioning rod 7 to be inserted into the positioning hole 6, which is used to fix the position of the connecting pipe 2, prevent the connecting pipe 2 from rotating, and improve the sealing effect of the connecting pipe 2. Then, the air pipe 3 is connected to the end of the connecting pipe 2. Through the operation of the inflation mechanism, air can be injected into the air pipe 3 and the sealing test piece 1 for the sealing test of the satellite communication antenna.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
