[0033] EMBODIMENT

[0034] Please refer to Figures 1-6 The present application provides a kind of low scattering carrier and the installation interface of antenna, including welding plate one 1, welding plate two 2, shielding assembly 3, positioning assembly 4, driving assembly 5, fixed assembly 6, via 7.

[0035] Further, welding plate one 1 and the mounting surface of low scattering carrier are welded and fixed together, welding plate two 2 and the mounting surface of antenna are welded and fixed together, welding plate one 1 and welding plate two 2 are used for the installation connection of low scattering carrier and antenna.

[0036] The welding plate one 1 and the welding plate two 2 are hollow inside, the welding plate one 1 and the welding plate two 2 are connected together, one end surface of the connection is slotted, so that the hollow interiors of the two welding plates form a closed space together, the closed space is provided with a positioning assembly 4, a driving assembly 5 and a fixing assembly 6.

[0037] Among them, the positioning assembly 4 makes the two separated welding plates position when connected, then the driving assembly 5 drives the fixed end in the fixing assembly 6 to displace, so as to fix and connect the two welding plates together, realize the installation and connection of the low scattering carrier and the antenna.

[0038] Preferably, the positioning assembly 4, the driving assembly 5 and the fixing assembly 6 are all located inside the welding plate, so that the scattering effect of each assembly located inside the welding plate is correspondingly reduced when the antenna is used and tested, thereby reducing the influence on the antenna.

[0039] Further, the welding plate one 1 and the welding plate two 2 are provided with a shielding assembly 3 outside, the shielding assembly 3 includes a shielding layer and a winding piece, the shielding layer has a shielding scattering effect, the shielding layer is a low scattering skin 301, the low scattering skin 301 is respectively slidably sleeved on the outer surfaces of the welding plate one 1 and the welding plate two 2, the winding piece is arranged in the closed space, one end of the low scattering skin 301 penetrates into the closed space and is woundly connected with the winding piece.

[0040] Preferably, the low scattering skin 301 outside the two welding plates is used to reduce the scattering of the welding plate and the inside thereof, and because the low scattering skin 301 is located outside the environment, the surface of the low scattering skin 301 will be damaged and cracked after a long time of use, which will affect the scattering shielding effect. At this time, the low scattering skin 301 can be rotated so that the damaged and cracked part of the low scattering skin 301 is slid into the winding piece. The winding piece stores a certain amount of low scattering skin 301 at this time. At this time, the new low scattering skin 301 will relatively slide out to the outside of the welding plate to replace the original damaged and cracked part, so that the scattering shielding effect of the device can be ensured without replacing the entire device.

[0041] In addition, the annular outermost surfaces of the welding plate one 1, the welding plate two 2 and the low scattering skin 301 are located on the same plane.

[0042] Preferably, one end surface of the welding plate one 1 and the welding plate two 2 is respectively welded with the low scattering carrier and the antenna, and the other end surface is connected with the corresponding welding plate. Therefore, only the annular outer surface of the welding plate is exposed to the external environment, which is the only reflection surface of the traveling wave scattering in the working or testing process of the antenna. The annular outer surface of the low scattering skin 301 outside the welding plate is also on the same plane with the outer surface of the welding plate, which reduces the generation of step structure, so that the entire device still has only one reflection surface, thereby reducing the reflection surface, ensuring the low scattering effect of the device and avoiding interference with the normal working or testing of the antenna.

[0043] Please refer toFigures 2-4 In the embodiment, the shielding assembly 3 comprises a low-scattering skin 301, a ring groove 302, a through hole 303, a roller 304, and a winding shaft set 305.

[0044] Specifically, the roller 304 is arranged outside the welding plate one 1 and the welding plate two 2 respectively, the ring groove 302 is arranged outside the welding plate one 1 and the welding plate two 2, the low-scattering skin 301 is sleeved and slid in the ring groove 302, so that the low-scattering skin 301 can rotate in the entire ring groove 302, and the roller 304 is vertically arranged at the ring groove 302 of the welding plate, the rotating surface of the roller 304 is located in the ring groove 302, and the rotating surface is in rolling abutment with the inner surface of the low-scattering skin 301. There is frictional resistance between the low-scattering skin 301 and the ring groove 302, so that the low-scattering skin 301 needs to be driven by external force to rotate in the ring groove 302, and when a person applies force at the roller 304, the frictional resistance between the low-scattering skin 301 and the ring groove 302 is reduced by the roller 304, and the low-scattering skin 301 is conveniently driven to rotate by the rolling of the roller 304.

[0045] In addition, the ring groove 302 is also provided with the through hole 303, the through hole 303 communicates the sealed space with the external environment, the winding shaft set 305 is fixedly arranged in the corresponding welding plate, one end of the low-scattering skin 301 is slid through the through hole 303 and wound on the winding shaft set 305. There is a gap between the low-scattering skin 301 slid into the inside and the low-scattering skin 301 slid out of the outside, so as to avoid contact, and the low-scattering skin 301 wound in the sliding gap between the two low-scattering skins 301 also shields the gap, so that the scattering shielding effect is not reduced.

[0046] The winding shaft set 305 is a winding member.

[0047] Please refer to Figure 4 The winding shaft set 305 is composed of at least one winding shaft, the winding shaft is arranged in the welding plate and is used for winding the excess low-scattering skin 301, so that the length of the low-scattering skin 301 is longer than the circumference of the ring groove 302, so that the low-scattering skin 301 located on the ring groove 302 can be manually slid on the ring groove 302 and the winding shaft, the damaged low-scattering skin 301 is put into the sealed space, and the low-scattering skin 301 wound in the winding shaft set 305 is slid out to be replaced, so that the low-scattering skin 301 can be quickly replaced.

[0048] Please refer to Figure 3 In the embodiment, the positioning assembly 4 comprises a positioning sleeve 401 and a positioning column 402.

[0049] Specifically, the positioning sleeve 401 is vertically fixed to the inner top surface of the welding plate one 1, the positioning column 402 is vertically fixed to the inner bottom surface of the welding plate two 2, and the positioning column 402 is vertically sleeved with the positioning sleeve 401. When the welding plate one 1 is connected with the welding plate two 2, the positioning sleeve 401 and the positioning column 402 will be vertically sleeved and slid, so as to position the installation position of the two welding plates, avoid relative rotation of the two welding plates, and avoid change of the relative installation angle of the low-scattering carrier and the antenna, thereby affecting the work of the antenna.

[0050] In the embodiment, two groups of asymmetric positioning sleeves 401 and positioning columns 402 are arranged in the two welding plates, so as to limit the rotation and connection direction of the welding plates.

[0051] Please refer to Figures 2-4 In the embodiment, the driving assembly 5 includes a ring plate 501 and an arc-shaped groove 502.

[0052] The fixing assembly 6 includes a sliding column 601, a sliding block 602, a slot plate 603, a clamping block 604, a clamping plate 605, and a slot 606.

[0053] Specifically, the ring plate 501 is rotationally arranged on the connecting surface of the welding plate two 2 and the welding plate one 1, and the arc-shaped groove 502 is arranged on the plate surface of the ring plate 501. One end of the arc-shaped groove 502 is close to the axis of the ring plate 501, and the other end of the arc-shaped groove 502 is close to the edge of the ring plate 501.

[0054] The sliding column 601 is slidably arranged in the arc-shaped groove 502, and the sliding block 602 is fixedly connected to one end of the sliding column 601 close to the welding plate two 2. The slot plate 603 is fixedly arranged on the inner bottom surface of the welding plate two 2, the sliding block 602 is slidably arranged in the slot of the slot plate 603, and the sliding direction of the sliding block 602 is transverse.

[0055] The outermost edge of the ring plate 501 is located in the external environment and is in the same plane as the annular outer surface of the welding plate. When the ring plate 501 is manually rotated, the arc-shaped groove 502 on the ring plate 501 is rotated, and the sliding column 601 is located at one end of the arc-shaped groove 502 close to the axis of the ring plate 501. The rotation of the arc-shaped groove 502 causes the relative sliding of the sliding column 601 to the other end of the arc-shaped groove 502 close to the edge of the ring plate 501, and the sliding column 601 is transversely and linearly displaced from the center of the welding plate to the edge of the welding plate under the sliding limitation of the sliding block 602 and the slot plate 603.

[0056] The clamping block 604 is fixedly connected to one end of the sliding column 601 close to the welding plate one 1, the clamping plate 605 is fixedly arranged on the inner side surface of the welding plate one 1, and the clamping block 604 is slidably connected with the clamping plate 605.

[0057] Therefore, when the slide post 601 is displaced to the edge of the welding plate, the clamping block 604 is close to the clamping plate 605 at the side of the welding plate, and then the bottom surface of the clamping block 604 is in sliding connection with the top surface of the clamping plate 605, thereby limiting the relative vertical displacement of the two welding plates and avoiding the two welding plates from being separated, so as to realize the fixation. The clamping plate 605 is further provided with a notch 606 for avoiding the slide post 601, so that the slide block 602 connected with the slide post 601 can normally slide.

[0058] The positioning direction of the positioning assembly 4 is vertical, which is perpendicular to the sliding direction of the clamping block 604, thereby limiting and fixing the two welding plates, and realizing the installation and connection of the low-scattering carrier and the antenna.

[0059] Please refer to Figure 1 and Figure 2 In the embodiment, the center of the welding plate one 1 and the welding plate two 2 is vertically penetrated by a through hole 7, when the welding plate one 1 and the welding plate two 2 are welded to the low-scattering carrier and the antenna respectively, the through hole 7 is communicated with the low-scattering carrier and the antenna respectively, so that the antenna and the low-scattering carrier can be connected by signal lines or power lines in the closed space of the low-scattering welding plate.
