Description

Technical Field

[0001] This utility model relates to the field of antenna turntable technology, and in particular to an antenna turntable with a limiting device. Background Technology

[0002] In modern communications, radar detection, aerospace, and other fields, antennas are core components for signal transmission and reception. The precise control of their operating angle and position directly determines signal transmission quality and detection efficiency. To achieve multi-directional adjustment and stable operation of the antenna, the antenna turntable becomes a key supporting device. It needs to use limiting devices to ensure that the antenna remains fixed at a specific angle or position, preventing antenna displacement due to external interference or equipment operation deviations, which would affect the overall system performance.

[0003] Chinese patent CN222763170U discloses a radar antenna turntable with a limiting device. The device controls the movement of the two fixed plates by rotating a bidirectional lead screw to clamp the rubber plate. The contact of the sliding plate and the sliding column confirms that the clamping is in place. The device has a simple structure and is easy to operate. However, the device can only clamp square objects and cannot adapt to objects of different shapes. In addition, the bidirectional lead screw is easily corroded when exposed to the outside for a long time, which will lead to incorrect accuracy during movement in the long run. Therefore, an antenna turntable with a limiting device is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an antenna turntable with a limiting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An antenna turntable with a limiting device includes a device plate, an intermediate frame mounted on the device plate, a lead screw mounted inside the device plate, an adjusting block connected to the outside of the lead screw, a side arm block provided on the outside of the adjusting block, a slide block movably connected to the side arm block, a limiting rod movably connected to the slide block, and a tensioning rod also provided on the slide block.

A first motor is mounted on the bottom surface of the device plate, and a bevel gear disk is provided on the output end of the first motor. The bevel gear disk and the multiple bevel gears mesh with each other.

[0007] Preferably, the outer surface of the lead screw is threaded with adjusting blocks, the adjusting blocks are movably connected in the adjusting groove, and an intermediate frame is fixedly installed at the middle position of the top surface of the device plate.

[0008] Preferably, side arm blocks are symmetrically installed on both sides of the adjusting block, and a sliding rod is installed on the top surface of each side arm block. Multiple limiting holes are arranged on the outer side surface of the side arm block.

[0009] Preferably, each slide rod is slidably connected to a slide block, each slide block is mounted with a horizontal rod, each horizontal rod has a base block movably connected to its outer surface, each base block has a limit rod mounted on its top, the base block and the slide block are connected by a spring, a contact plate is horizontally mounted on one side of the base block, an inner groove is formed in the tail end of the slide block, the contact plate is movably connected in the inner groove, an indicator light is mounted on the outer side of the tail end of the slide block, a push switch is installed in the inner groove, and the contact plate is connected to one side of the push switch.

[0010] Preferably, a tension lever is spring-connected to the bottom side of the slide block, and one end of the tension lever is connected to a limiting hole.

[0011] The beneficial effects of this utility model are: This solution allows for convenient placement of the base via a central support platform, synchronous rotation of the lead screw via a bevel gear disc, easy adjustment of the slide position via a tension clamp, clamping and limiting of the base via a limit rod, protection of the lead screw via a contact plate, and control of indicator lights.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example: Refer to Figure 1-6 An antenna turntable with a limiting device includes a device plate 1, an intermediate frame 2 mounted on the device plate 1, a lead screw 4 mounted inside the device plate 1, an adjusting block 3 connected to the outside of the lead screw 4, a side arm block 6 provided on the outside of the adjusting block 3, a slide block 7 movably connected to the side arm block 6, a limiting rod 8 movably connected to the slide block 7, and a tensioning rod 14 provided on the slide block 7. Multiple adjusting slots are provided on the device plate 1, each of which is rotatably connected to a lead screw 4. A bevel gear 17 is mounted on one end of each lead screw 4. A first motor 15 is mounted on the bottom surface of the device plate 1, and a bevel gear disk 16 is provided on the output end of the first motor 15. The bevel gear disk 16 and the multiple bevel gears 17 mesh with each other to control the lead screw 4 to rotate synchronously, thereby causing the adjusting block 3 to move synchronously.

[0017] Specifically, adjusting blocks 3 are threadedly connected to the outer surface of the lead screw 4. The adjusting blocks 3 are movably connected in the adjusting groove. An intermediate support 2 is fixedly installed in the middle of the top surface of the device plate 1 to facilitate the placement of the base.

[0018] Furthermore, side arm blocks 6 are symmetrically installed on both sides of the adjusting block 3. Slide rods 5 are installed on the top surface of each side arm block 6. Multiple limiting holes 9 are arranged on the outer side surface of the side arm block 6 to adjust the left and right positions of the limiting rod 8, which is convenient to adapt to bases of different shapes. Rubber clamping rings are provided on the limiting rod 8 to reduce clamping slippage.

[0019] Furthermore, each slide rod 5 is slidably connected to a slide seat 7, and a horizontal rod is installed on the slide seat 7. A base block 10 is movably connected to the outer surface of each horizontal rod. A limit rod 8 is installed on the top of each base block 10. The base block 10 and the slide seat 7 are connected by a spring. A contact plate 11 is also horizontally installed on one side of the base block 10. An inner groove 13 is opened in the tail end of the slide seat 7. The contact plate 11 is movably connected in the inner groove 13. An indicator light 12 is also installed on the outer side of the tail end of the slide seat 7. A push switch is installed in the inner groove 13. The contact plate 11 is connected to one side of the push switch and is used for pressing to trigger the limit rod 8 after it is clamped in place for a prompting function.

[0020] In this embodiment, a tension lever 14 is spring-connected to the bottom side of the slide block 7. One end of the tension lever 14 is connected to the limiting hole 9 for convenient and quick adjustment of the position of the slide block 7.

[0021] Working principle: When in use, place the base on the intermediate frame 2, adjust the position of the limiting rod 8 according to the shape of the base, and pull the tension rod 14 outward during the adjustment process. After adjusting to the appropriate position, release it, and the tension rod 14 will be locked into the limiting hole 9 to complete the positioning. Then, control the first motor 15 to rotate, and the bevel gear 16 will start to rotate. During the rotation, it will drive the bevel gear 17 to rotate, the lead screw 4 will start to rotate, and the adjusting block 3 will start to move forward until the limiting rod 8 contacts the base. At this time, the lead screw 4 will continue to rotate, and the contact force between the limiting rod 8 and the base will become larger and larger. The limiting rod 8 and the bottom block 10 will move backward until the rear side of the contact plate 11 contacts the push switch of the indicator light 12. At this time, the first motor 15 stops rotating.
