Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency rotary joints, and particularly relates to an installation structure of a broadband coaxial radio frequency rotary joint. Background Technique

[0002] In many applications, such as radar systems, wireless communication devices, and antenna scanning systems, high-frequency signals need to be transmitted. The broadband coaxial radio frequency rotary joint can support a wider frequency range to meet the requirements of modern communication systems for high-speed data transmission. The materials of the main housing and the flange should have good electrical conductivity, mechanical strength, and corrosion resistance to adapt to the special requirements of the radio frequency microwave transmission system. The existing threaded connection between the main housing and the flange is prone to loosening when used for a long time or under the action of vibration and impact external forces. This loosening leads to connection failure and even causes equipment failures or safety accidents. Under strong vibration or impact, the threaded connection without a locking and anti-detachment structure may completely fall off, causing equipment damage. Content of the Utility Model

[0003] The purpose of the utility model is to provide an installation structure of a broadband coaxial radio frequency rotary joint. By using this device for work, the problem of poor locking and anti-detachment effect of the existing installation structure of the broadband coaxial radio frequency rotary joint is solved.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An installation structure of a broadband coaxial radio frequency rotary joint, including a main housing and a flange, an internal thread opened on the inner surface of the main housing, and an external thread opened on the outer surface of the flange. An extension ring is arranged on the outer side of the flange, and a pressing structure is arranged on one side of the extension ring.

[0005] The pressing structure includes a groove opened on the surface of the extension ring, a rotating rod rotatably connected inside the groove, a first gear arranged on the surface of the rotating rod, a first rack meshed with one side of the first gear, a pressing ring arranged at one end of the first rack extending out of the extension ring, a second gear is also arranged on the surface of the rotating rod, and a second rack is meshed with one side of the second gear.

[0006] A toothed plate is arranged at one end of the second rack close to the external thread, and a locking structure for engaging with the toothed plate is arranged on the outer side of the main housing.

[0007] Furthermore, a sliding groove is embedded inside the groove, two groups of sliding grooves are symmetrically embedded, and each of the two groups of sliding grooves is slidably connected with a slider. The two sliders are respectively connected with the first rack and the second rack.

[0008] One ends of the sliders are respectively provided with springs, and the springs are respectively connected with the corresponding sliding grooves.

[0009] Furthermore, the locking structure includes an extension block provided on the outer surface of the main housing. A storage groove is formed on the surface of the extension block. A pressing plate is slidably connected inside the extension block. Clamping blocks are provided on both sides of the pressing plate, and clamping grooves are correspondingly formed on the surface of the extension block.

[0010] Furthermore, a channel is formed inside the extension block. A convex block is slidably connected inside the channel. A driven block is provided at one end of the convex block.

[0011] Furthermore, a tension spring is provided at one end of the convex block, and the tension spring is connected to the channel.

[0024] The present invention will be further described below in conjunction with the embodiments.

[0025] Embodiment 1:

[0026] Please refer to Figures 1 - 4 , the pressing structure 6 includes a groove 61 opened on the surface of the extension ring 5, a rotating rod 62 rotatably connected inside the groove 61, a first gear 63 arranged on the surface of the rotating rod 62, a first rack 64 meshing with one side of the first gear 63, a pressing ring 65 arranged at one end of the first rack 64 extending out of the extension ring 5, a second gear 69 also arranged on the surface of the rotating rod 62, a second rack 610 meshing with one side of the second gear 69, a toothed plate 7 arranged at one end of the second rack 610 close to the external thread 4, a chute 68 embedded inside the groove 61, two groups of chutes 68 are symmetrically embedded, and two sliders 66 are respectively slidably connected inside the two groups of chutes 68. The two sliders 66 are respectively connected to the first rack 64 and the second rack 610, and springs 67 are respectively arranged at one ends of the sliders 66, and the springs 67 are respectively connected to the corresponding chutes 68, so as to prevent the main housing 1 from loosening when shaking with the flange 3 by external force during use.

[0027] A locking structure 8 for engaging with the toothed plate 7 is provided on the outer side of the main housing 1. The locking structure 8 includes an extension block 81 provided on the outer surface of the main housing 1. A receiving groove 82 is formed on the surface of the extension block 81. A pressing plate 88 is slidably connected inside the extension block 81. Clamping blocks 89 are provided on both sides of the pressing plate 88. Corresponding card slots 810 are formed on the surface of the extension block 81. A channel 87 is formed inside the extension block 81. A convex block 85 is slidably connected inside the channel 87. One end of the convex block 85 is provided with a driven block 84. A tension spring 86 is provided at one end of the convex block 85. The tension spring 86 is connected to the channel 87. One side of the pressing plate 88 is inclined. One side of the driven block 84 close to the pressing plate 88 is inclined. The inclined surface of the pressing plate 88 is fitted with the inclined surface of the driven block 84. A clamping plate 83 is provided on one side of the driven block 84. The teeth of the clamping plate 83 are arranged in the opposite direction to the teeth of the toothed plate 7, improving the installation stability.

[0028] Specifically, first, the internal thread 2 of the main housing 1 is rotationally thread-connected with the external thread 4 of the flange 3, so that the main housing 1 squeezes and pushes the pressure ring 65. The pressure ring 65 pushes the first rack 64 into the inside of the groove 61. The first rack 64 meshes with the first gear 63. The first gear 63 drives the rotating rod 62 to rotate. The rotating rod 62 is rotatably connected to the groove 61. The rotating rod 62 drives the second gear 69 to rotate and mesh with the second rack 610. The second rack 610 drives the toothed plate 7 at the extended end to move into the receiving groove 82 formed on the surface of the extension block 81. Moreover, the first rack 64 and the second rack 610 drive the slider 66 on one side to slide in the sliding groove 68. The slider 66 drives the spring 67 to stretch and store energy. After the toothed plate 7 enters the receiving groove 82 formed on the surface of the extension block 81, by pressing the pressing plate 88 to move into the extension block 81, the clamping blocks 89 at both ends of the pressing plate 88 are engaged with the corresponding card slots 810 formed on the surface of the extension block 81, so that the inclined surface at one end of the pressing plate 88 pushes the inclined surface of the engaged driven block 84. Thus, the driven block 84 drives the clamping plate 83 to move towards the toothed plate 7. The driven block 84 drives the convex block 85 to move inside the channel 87. The convex block 85 drives the tension spring 86 to stretch and store energy. Further, the driven block 84 drives the teeth of the clamping plate 83 to engage with the teeth of the toothed plate 7, thereby preventing the main housing 1 from loosening when shaken by an external force during use with the flange 3, preventing detachment, and improving the installation stability.
