Description

Technical Field

[0001] This invention relates to the field of antenna steering device technology, specifically to a pneumatic fully automatic EMC antenna steering device and its manufacturing method. Background Technology

[0002] EMC antennas, also known as electromagnetic compatibility antennas, are similar in appearance to traditional antennas. They transmit signals by radiating and receiving electromagnetic wave energy. They are used for electromagnetic interference measurement and electromagnetic susceptibility measurement in electromagnetic compatibility testing. In order to test or improve the signal transmission and reception effect, EMC antennas need to be able to rotate at a certain angle. Therefore, an EMC antenna turning device is required.

[0003] Existing EMC antenna turning devices typically use pneumatic or electric equipment to provide power, which, in conjunction with the internal transmission structure, enables the EMC antenna to turn. The continuous power supply allows the EMC antenna to continuously turn during operation to achieve the purpose of detection or signal transmission.

[0004] However, in actual use, the antenna turning process of the above-mentioned devices is mostly in the form of mechanical movement, which makes the antenna prone to shaking during turning, thus reducing the transmission efficiency of the antenna. In view of this, we propose a pneumatic fully automatic EMC antenna turning device and its manufacturing method. Summary of the Invention

The bottom inner wall of the movable sleeve is fixedly connected to the bottom end of a tension spring. The top end of the tension spring is fixedly connected to the lower surface of the connecting block. The top surface of the connecting block is fixedly installed with the bottom end of a connecting rod. The top end of the connecting rod is hinged to the bottom end of a pull rod. The top end of the pull rod is hinged to the inner wall of the support rod.

[0015] Preferably, the top outer wall of the movable sleeve has a through hole that matches the outer diameter of the connecting rod, and the connecting rod passes through the through hole and is slidably connected to the movable sleeve.

[0032] like Figure 1-5 As shown, the present invention provides a technical solution: a pneumatic fully automatic EMC antenna turning device and its manufacturing method, comprising a base 1, a placement cylinder 2 rotatably mounted on the bottom inner wall of the base 1, a placement cavity 3 formed in the inner wall of the placement cylinder 2, a stabilizing component 4 disposed inside the base 1, the stabilizing component 4 including a driving cylinder 41, a driving gear 42 fixedly mounted on the output end of the driving cylinder 41, a driven gear 43 passing through the placement cylinder 2 and fixedly connected to the placement cylinder 2, and a hinge seat 44 fixedly mounted on the upper surface of the base 1, with a support rod 4 hinged to the upper surface of the hinge seat 44. At the bottom of 5, a collar 46 is hinged to the top of the support rod 45. A slide rod 47 is slidably installed on the inner wall of the collar 46. A fixing plate 48 is fixedly installed on the right end of the slide rod 47. The left end of a telescopic rod 49 is fixedly connected to the inner wall of the collar 46. The right end of the telescopic rod 49 is fixedly connected to the left outer wall of the fixing plate 48. The left end of a retaining spring 410 is fixedly connected to the inner wall of the collar 46. The right end of the retaining spring 410 is fixedly connected to the left outer wall of the fixing plate 48. A mounting base 411 is fixedly installed on the left end of the slide rod 47. A contact ball 412 is provided on the left inner wall of the mounting base 411.

[0033] In one embodiment of the present invention, the placement cylinder 2 is located at the center of the base 1, and a limiting ring is provided on the arc-shaped outer wall of the placement cylinder 2. Specifically, the inner wall of the base 1 has a circular through hole that matches the arc-shaped outer wall of the placement cylinder 2, and a limiting groove that matches the limiting ring is provided on the arc-shaped inner surface of the circular through hole, thereby ensuring the stable rotation of the placement cylinder 2. At the same time, multiple sets of fastening bolts are provided on the arc-shaped outer wall of the placement cylinder 2, and the multiple sets of fastening bolts allow the EMC antenna to be inserted into the placement cavity 3 and fixed, thereby allowing the EMC antenna to be fixedly installed in the placement cylinder 2. Internally, the driven gear 43 meshes with the driving gear 42 to achieve transmission. When the drive cylinder 41 is started, it works with the driving gear 42 to make the driven gear 43 drive the placement cylinder 2 to rotate, which in turn causes the EMC antenna fixed in the placement cavity 3 to rotate. In addition, there are two sets of hinge seats 44, and the two sets of hinge seats 44 are symmetrically arranged about the central axis of the base 1. At the same time, a circular through hole adapted to the placement cavity 3 is opened at the center of the collar 46, so that the EMC antenna can be inserted into the placement cavity 3 after passing through the collar 46 during installation.

[0034] In an embodiment of the present invention, six sets of slide rods 47 are provided, and the six sets of slide rods 47 are evenly distributed in a circumferential array on the inner surface of the circular through hole of the collar 46. Meanwhile, the telescopic rod 49 is hollow inside, and the diameter of the internal cavity of the telescopic rod 49 is larger than the outer diameter of the slide rod 47. This prevents interference between the telescopic rod 49 and the slide rod 47, thereby ensuring the relative stability of the device during operation. Furthermore, a retaining spring 410 is sleeved on the outside of the telescopic rod 49, allowing the telescopic rod 49 to adjust to the deformation direction of the retaining spring 410. It serves to guide and restrict. Specifically, the clamping spring 410 always maintains the deformation direction in the horizontal direction when it is compressed or stretched, and will not bend in the vertical direction under its own weight or when it is compressed. This allows the clamping spring 410 to always provide a stable transmission effect for the fixed plate 48. Furthermore, the contact ball 412 is located at the center of the collar 46, so that the contact ball 412 corresponding to the six sets of slide bars 47 always keeps in contact with the surface of the EMC antenna, ensuring that it will not bend or tilt during rotation.

[0035] In addition, to ensure the stability of the collar 46 and prevent the collar 46 from tilting or shaking, a tensioning component 5 is provided on the upper surface of the base 1. The tensioning component 5 includes a fixed sleeve 51. The fixed sleeve 51 is fixedly installed on the upper surface of the base 1. A telescopic cylinder 52 is fixedly installed on the bottom inner wall of the fixed sleeve 51. The output end of the telescopic cylinder 52 is fixedly connected to the bottom end of the movable sleeve 53. The bottom inner wall of the movable sleeve 53 is fixedly connected to the bottom end of the telescopic rod 54. The top end of the telescopic rod 54 is fixedly connected to the lower surface of the connecting block 55. The bottom inner wall of the movable sleeve 53 is fixedly connected to the bottom end of the tension spring 56. The top end of the tension spring 56 is fixedly connected to the lower surface of the connecting block 55. The bottom end of the connecting rod 57 is fixedly installed on the upper surface of the connecting block 55. The top end of the connecting rod 57 is hinged to the bottom end of the pull rod 58. The top end of the pull rod 58 is hinged to the inner wall of the support rod 45.

[0036] In an embodiment of the present invention, two sets of tensioning components 5 are provided, and the two sets of tensioning components 5 are symmetrically arranged with the central axis of the base 1 as the axis of symmetry. In addition, the top outer wall of the movable sleeve 53 is provided with a through hole that matches the outer diameter of the connecting rod 57, and the connecting rod 57 slides through the through hole and is slidably connected to the movable sleeve 53. At the same time, the tension spring 56 is sleeved on the outside of the telescopic rod 54, so that the telescopic rod 54 can guide and restrict the deformation direction of the tension spring 56. Furthermore, the outer surface of the connecting block 55 is square, and the inner wall of the fixed sleeve 51 is provided with a square shape that matches the outer surface of the connecting block 55, so that the connecting block 55 always maintains the vertical deformation direction in the inner wall of the fixed sleeve 51.

[0037] In addition, in order to improve the stability of the EMC antenna in the placement cavity 3 and avoid vertical shaking and deviation, a fastening component 6 is provided inside the placement cylinder 2. The fastening component 6 includes a receiving cavity 61. The receiving cavity 61 is opened on the inner surface of the placement cavity 3. The left end of the transmission rod 62 is hinged to the bottom inner wall of the receiving cavity 61, and the right end of the transmission rod 62 is hinged to the contact block 63. The end of the hinge rod 64 is hinged to the inner wall of the transmission rod 62, and the other end of the hinge rod 64 is fixedly connected to the end of the elastic member 65.

[0038] In embodiments of the present invention, multiple sets of the bonding components 6 are arranged in a circular array on the arc-shaped inner wall of the placement cavity 3. Simultaneously, the outer wall of the contact block 63 near the center of the placement cavity 3 is formed into an arc surface, allowing the contact block 63 to fit more tightly against the outer wall of the EMC antenna. Furthermore, two sets of the transmission rods 62 are arranged symmetrically about the central axis of the accommodating cavity 61, ensuring that the contact blocks 63 corresponding to the two sets of transmission rods 62 can better align with the EMC antenna in the vertical direction. To limit the vertical movement of the line, two sets of hinge rods 64 are provided, and the two sets of hinge rods 64 are respectively fixedly installed at both ends of the elastic member 65. The elastic member 65 is hinged to the two sets of transmission rods 62 through the hinge rods 64 fixedly connected at both ends, so that the elastic member 65 can better transmit the two sets of transmission rods 62. At the same time, the elastic member 65 is composed of a telescopic member with freely extendable length and a spring, so that the elastic member 65 can always maintain good restoring ability when stretched or compressed.

[0039] In this invention, during use, the EMC antenna is inserted into the placement cavity 3 through the circular through hole at the center of the collar 46. At this time, the fastening bolts on the arc-shaped outer wall of the placement cylinder 2 are tightened, thus fixing the EMC antenna inside the placement cylinder 2. Simultaneously, the drive cylinder 41 is activated, cooperating with the drive gear 42 and the driven gear 43, so that the placement cylinder 2 can rotate on the bottom inner wall of the base 1, thereby driving the EMC antenna to rotate, thus improving the signal transmission and reception efficiency of the EMC antenna. Furthermore, to prevent instability during the rotation of the EMC antenna, a stabilizing component 4 is provided, cooperating with the support rod 45 and the collar 46, so that the retaining spring 410 and the contact ball 412 are tightly fitted against the outer wall of the EMC, ensuring that the EMC antenna does not wobble without affecting its rotation, thus improving its operational stability. In addition, to ensure the stability of the collar 46 and prevent it from tilting or wobbling, a tensioning component 5 is provided. This, in conjunction with the telescopic cylinder 52, allows the connecting rod 57 inside the movable sleeve 53 to pull the pull rod 58 downwards, thereby causing the support rod 45 to move downwards. Since the length of the support rod 45 is fixed, the pull rod 58 can firmly hold the support rod 45, preventing it from wobbling when the EMC antenna rotates. Simultaneously, to improve the stability of the EMC antenna within the placement cavity 3 and prevent vertical shaking or offset, a clamping component 6 is provided. This, in conjunction with the elastic element 65, ensures that the two sets of transmission rods 62 and contact blocks 63 are tightly fitted to the outer wall of the EMC antenna, thus preventing vertical shaking after installation and ensuring the operational stability of the EMC antenna.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
