Detailed Implementation

[0022] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] It should be noted that the terms "comprising" and "having," and any variations thereof, in the embodiments and drawings of this specification are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0024] This specification discloses a horn antenna angle adjustment device, which will be described in detail below.

[0025] Figure 1 This is a schematic diagram of a horn antenna angle adjustment device provided in one embodiment of this specification. Figure 1 As shown, a horn antenna angle adjustment device includes a horn antenna 1, a rotating shaft 2, a support plate 3, an antenna fixing plate 4, a rotating sliding sleeve 5, a locking screw 6, a base 7, and a sliding assembly 8. Figure 2 This is a top view of a horn antenna angle adjustment device provided in one embodiment of this specification.

[0026] Support plates 3 are vertically fixed to the base 7. There are two support plates 3, arranged opposite each other. In a specific embodiment, the support plates are fixed to the base with screws. The support plates, fixed to the base, provide support and fixation for the rotating shaft.

[0027] The rotating shaft 2 is fixedly connected to two support plates 3 and is located between the two support plates 3 at one end away from the base 7.

[0028] Antenna fixing plate 4 is set between two support plates 3. A sleeve structure is provided at one end of antenna fixing plate 4 near the rotating shaft 2. The size of the sleeve is adapted to the size of the rotating shaft 2. Antenna fixing plate 4 is sleeved on the rotating shaft 2.

[0029] The horn antenna 1 is fixed to the antenna mounting plate 4. In practice, the horn antenna is fixed to the antenna mounting plate with screws.

[0030] Figure 3 This is a schematic diagram of the structure of a rotating sliding sleeve of a horn antenna angle adjustment device provided in one embodiment of this specification. Figure 3 As shown, the rotary sleeve 5 includes a slide rod 501 and a sleeve 502.

[0031] One end of the slide rod 501 is fixed to the antenna mounting plate 4, and the other end of the slide rod 501 is connected to the sliding sleeve 502. The sliding sleeve 502 has a groove inside, and the slide rod 501 slides along the groove of the sliding sleeve 502. The end of the sliding sleeve 502 away from the slide rod 501 has a shaft hole, and the opening direction of the shaft hole is parallel to the axis of the rotating shaft 2. The slide rod is fixed to the antenna mounting plate by screws.

[0032] The rotary sliding sleeve consists of a sliding rod and a sliding sleeve. One end of the sliding sleeve has a shaft hole that allows it to rotate around the shaft. The groove at the other end of the sliding sleeve and the sliding rod form a sliding pair. The sliding rod can move along the groove of the sliding sleeve. The sliding pair of the rotary sliding sleeve can compensate for the change in distance between the slider and the antenna fixing plate during antenna adjustment.

[0033] The sliding assembly 8, fixed to the base 7, includes a lead screw and a slider. The slider slides along the lead screw, and the sliding direction of the slider is perpendicular to the axis of the rotating shaft 2. The slider is connected to the shaft hole of the rotary sleeve 5. The lead screw of the sliding assembly is a trapezoidal lead screw with a self-locking function. The slider of the sliding assembly has a pre-drilled shaft structure that can pass through the shaft hole of the rotary sleeve.

[0034] The slider on the sliding assembly is connected to the antenna mounting plate via a rotary sleeve. The rotary sleeve has rotation and length compensation functions, which can convert the linear motion of the slider into the rotational motion of the antenna mounting plate. Driven by the lead screw, the slider pushes the antenna mounting plate to rotate, thereby realizing the adjustment of the antenna pitch angle.

[0035] The locking screw 6 is located at one end of the sliding assembly 8 and is used to lock the lead screw of the sliding assembly 8.

[0036] Because the lead screw on the sliding assembly has a self-locking function, the antenna position is very stable after adjustment, and there will be no shaking or instability. In addition, the locking screw can lock the lead screw to prevent human error from causing the antenna position to change.

[0037] The lead screw of the sliding component 8 drives the slider to move, and the slider moves to rotate the antenna fixing plate 4 through the rotary sliding sleeve 5, thereby changing the elevation angle of the horn antenna 1.

[0038] The working principle of the embodiments in this specification is as follows: In this device, the support plate 3 is fixed on the base 7 to support and fix the rotating shaft 2. The horn antenna 1 is directly fixed on the antenna fixing plate 4, which can rotate around the rotating shaft 2. The rotating shaft 2, support plate 3, and antenna fixing plate 4 realize the basic function of rotating the horn antenna. The sliding component 8 includes a lead screw and a slider, the bottom of which is fixed on the base 7. The slider can slide back and forth in a straight line under the drive of the lead screw. Since the trapezoidal lead screw has a self-locking function, the slider can stop steadily at the current position after the lead screw stops driving. Based on this characteristic of the lead screw, the positional stability of the sliding component is very good. The rotating sleeve 5 is composed of a sliding rod 501 and a sleeve 502. One end of the sleeve has a shaft hole that can rotate around the shaft. The groove at the other end of the sleeve and the sliding rod form a sliding pair. The rod can move along the groove of the sliding sleeve, and the moving joint of the rotary sliding sleeve 5 can compensate for the distance change between the slider and the antenna fixing plate during antenna adjustment. The rotary sliding sleeve 5 is used to connect the sliding assembly 8 and the antenna fixing plate 4. The sliding sleeve 502 is directly connected to the slider in the sliding assembly, and the sliding rod 501 is fixed to the antenna fixing plate 4. The slider drives the antenna fixing plate 4 to rotate through the rotary sliding sleeve 5 to adjust the pitch angle of the horn antenna 1. During the antenna adjustment process, the straight distance between the slider and the antenna fixing plate 4 is constantly changing. The sliding rod 501 in the rotary sliding sleeve 5 can move along the sliding sleeve 502 to compensate for the distance change. In order to avoid human error after the antenna pitch angle is adjusted, the locking screw 6 is used to lock the lead screw in the sliding assembly 8, which further improves the stability of the entire device.

[0039] Based on the technical solutions described above, some more specific technical solutions are provided below, which will be elaborated on separately.

[0040] In an optional embodiment, the groove inside the rotary sleeve can be a dovetail groove, and the end of the slide rod is a dovetail block adapted to the dovetail groove; a ring-shaped lubrication groove can be provided on the inner wall of the shaft hole of the sleeve, and the lubrication groove is filled with grease.

[0041] In this embodiment, the rotary sleeve has a groove inside, which adopts a dovetail groove structure. Correspondingly, the end of the slide rod is machined into a dovetail block that matches the dovetail groove. The slide rod achieves a sliding connection with the slide sleeve by means of the dovetail block fitting into the dovetail groove inside the sleeve. This dovetail fit structure not only provides precise guidance for the sliding direction of the slide rod but also effectively limits the relative displacement between the slide rod and the sleeve in the direction perpendicular to the sliding direction, ensuring the stability of the connection and the accuracy of the movement. Furthermore, an annular lubrication groove is machined on the inner wall of the shaft hole of the sleeve. This lubrication groove is filled with grease, so that when the slide rod moves relative to the shaft hole of the sleeve, the grease in the lubrication groove continuously provides lubrication to the mating surfaces of the slide rod and the shaft hole, reducing frictional resistance and wear, thereby improving the smoothness of the overall movement of the rotary sleeve and the service life of the components.

[0042] In an optional embodiment, the sliding assembly further includes two optical axis guide rails parallel to the lead screw. The two ends of the optical axis guide rails are fixed to the base by L-shaped brackets. The horizontal section of the L-shaped brackets is connected to the base by bolts, and the vertical section of the L-shaped brackets is interference-fitted with the end of the optical axis guide rails. The slider has guide holes adapted to the optical axis guide rails, and the slider is sleeved on the two optical axis guide rails through the guide holes.

[0043] In this embodiment, the sliding assembly also includes two optical axis guide rails parallel to the lead screw, with both ends of the guide rails fixed to the base via L-shaped brackets. Specifically, the horizontal section of the L-shaped bracket can be firmly connected to the base with bolts, while its vertical section can be tightly fixed to the ends of the optical axis guide rails using an interference fit. The slider has guide holes precisely fitted to the optical axis guide rails, allowing the slider to be simultaneously fitted onto both optical axis guide rails. This dual-guide rail fit structure provides stable linear motion guidance for the slider, effectively preventing radial offset or torsion during lead screw drive. When the interference-fit L-shaped brackets firmly constrain the optical axis guide rails, the precise and constant guide rail spacing is ensured, thereby guaranteeing the straightness of the slider's trajectory. The dual constraint formed by the slider and the optical axis guide rails through the dual guide holes not only distributes the load but also improves the slider's resistance to off-center loads and stability during movement.

[0044] In an optional embodiment, the antenna fixing plate is provided with three reinforcing ribs arranged in a triangular pattern. One end of the three reinforcing ribs converges at the outer wall of the sleeve structure, and the other end extends to the three corners of the antenna fixing plate. The side of the antenna fixing plate used to fix the horn antenna is provided with a boss, and the boss is provided with multiple threaded holes for installing the horn antenna.

[0045] In this embodiment, the antenna mounting plate has three reinforcing ribs arranged in a triangular pattern. One end of each rib converges and connects to the outer wall of the sleeve structure, while the other end extends to the three corners of the antenna mounting plate. Specifically, this radial triangular rib arrangement forms a stable truss support structure, enabling the antenna mounting plate to effectively transfer the cantilever bending moment to the pivot support point when bearing the load of the horn antenna, thus enhancing its resistance to bending and torsional deformation. Furthermore, a boss is provided on the side of the antenna mounting plate used to fix the horn antenna. This boss protrudes from the surface of the antenna mounting plate and is precision-machined to ensure flatness. Multiple symmetrically distributed threaded holes are provided on the boss, which are used to securely fix the horn antenna with mounting screws. The boss design increases the effective connection depth of the threaded holes and, by separating the mounting base from the main body of the mounting plate, avoids the impact of uneven plate surface on antenna installation accuracy, thereby ensuring the stability and pointing accuracy of the antenna installation.

[0046] In an optional embodiment, the bottom of the base is provided with a plurality of waist-shaped mounting holes for connecting to an external mounting surface, the length direction of the waist-shaped mounting holes being consistent with the sliding direction of the slider; and the base is also provided with a protective shell for covering the sliding assembly, and one side of the protective shell is provided with a strip-shaped opening for the sliding sleeve of the rotary sliding sleeve to pass through.

[0047] In this embodiment, the base has multiple waist-shaped mounting holes at its bottom for connection to an external mounting surface. The length direction of these holes aligns with the sliding direction of the slider. This design allows for slight adjustments to the base's position along the length of the waist-shaped holes before bolting it to the external mounting surface. This ensures precise calibration and that the slider's sliding trajectory is parallel to the reference direction required by the external system, effectively eliminating the impact of accumulated installation errors on antenna angle adjustment accuracy. Simultaneously, a protective shell for the sliding assembly is provided on the base. This shell can be made of metal or engineering plastic and connected to the base with screws. This effectively prevents dust, moisture, and other foreign matter from entering the precision moving parts of the sliding assembly, such as the lead screw and optical axis guide, preventing jamming, wear, or corrosion caused by contamination. Furthermore, a strip-shaped opening is provided on one side of the protective shell for the sliding sleeve to pass through. The opening's direction aligns with the slider's sliding direction, and its length must ensure that the sliding sleeve can pass freely without interfering with the protective shell during the slider's full movement and rotation around the connecting shaft.

[0048] In an optional embodiment, the slide bar is provided with a scale along its length, and each scale is provided with a locking component for structural interference with the slide sleeve; wherein, the locking component is an elastic positioning pin or a set screw, and the slide sleeve is provided with a corresponding lock hole for the locking component to be inserted.

[0049] In this embodiment, the slide rod has graduations along its length, and each graduation is equipped with a locking component to create structural interference with the sliding sleeve. Specifically, the slide rod surface can be precision-machined to form graduations representing specific telescopic lengths and corresponding values. When the sliding component drives the slider to move and adjusts the antenna elevation angle to a desired fixed position by rotating the sliding sleeve, the operator can slide the sliding sleeve along the slide rod until the locking hole on the sliding sleeve aligns with the mounting hole of the locking component at the desired graduation on the slide rod. If an elastic positioning pin is used, its pin can automatically spring into the aligned locking hole under the action of an internal spring, achieving a quick "click" lock and providing tactile and audible confirmation feedback. This method facilitates frequent and rapid positioning and unlocking. If a set screw is used, the end can be manually rotated to firmly press into the locking hole or against the graduation plane of the slide rod, utilizing the preload generated by the thread to achieve a more secure mechanical lock, effectively resisting accidental displacement caused by vibration.

[0050] In this embodiment, the design of the scale and locking component allows the length of the rotating sleeve to be precisely fixed at multiple discrete preset positions, thereby indirectly limiting the adjustment range of the antenna elevation angle and providing a reliable reference for the repeated positioning of the antenna.

[0051] In an optional embodiment, the antenna mounting plate is provided with an angle indicator disk, and the support plate is provided with a pointer that cooperates with the angle indicator disk.

[0052] In this embodiment, an angle indicator disk is provided on the antenna mounting plate, and a pointer that cooperates with the angle indicator disk is provided on the support plate. The angle indicator disk can be precisely marked with angle scales directly on the side of the antenna mounting plate's rotation center using etching or printing processes. This scale range can cover the effective pitch adjustment range of the horn antenna. The pointer can be made of rigid metal wire or a thin sheet, and its base is securely mounted to the adjacent support plate sidewall with screws, pointing towards the angle indicator disk. Therefore, when the antenna mounting plate rotates around its axis to adjust the antenna pitch angle, the position of the pointer relative to the angle indicator disk changes accordingly. The operator can directly read the scale value pointed to by the pointer tip to obtain the accurate pitch angle of the current antenna in real time and intuitively, improving the intuitiveness and operational efficiency of angle adjustment and effectively avoiding errors caused by visual estimation.

[0053] In an optional embodiment, a sliding bearing or lubricating bushing is provided between the rotating shaft and the sleeve structure of the antenna fixing plate.

[0054] In this embodiment, a sliding bearing or a lubricating bushing is provided between the rotating shaft and the sleeve structure of the antenna fixing plate. If a sliding bearing is used, it can be made of a low-friction material such as copper-based or plastic composite material, nested between the inner wall of the sleeve structure and the outer surface of the rotating shaft. Its self-lubricating properties reduce frictional resistance during rotation, ensuring smooth and accurate rotation of the antenna fixing plate around the shaft, while extending the service life of both the shaft and the sleeve. Alternatively, if a lubricating bushing is used, it is made of oil-impregnated metal or polymer material, press-fitted into the sleeve structure. The lubricant pre-impregnated in its internal microporous structure is continuously released during rotation, forming a uniform oil film, effectively reducing wear and preventing jamming due to long-term use.

[0055] In an optional embodiment, one end of the lead screw of the sliding assembly is connected to a handwheel or an adjustment knob.

[0056] In this embodiment, a handwheel or adjustment knob is connected to one end of the lead screw of the sliding assembly. The handwheel can be made of metal or engineering plastic and is fixedly connected to the end of the lead screw via a keyway. Its outer rim can have anti-slip textures to increase friction during operation, thus facilitating manual rotation to drive the lead screw. Alternatively, an adjustment knob can be directly fixed to the extended end of the lead screw with a set screw. Its outer circumferential surface can be machined with multiple evenly distributed grooves or knurling to facilitate force application. The operator can directly drive the lead screw to rotate by rotating the handwheel or adjustment knob clockwise or counterclockwise, thereby precisely controlling the linear displacement of the slider along the lead screw axis. This linear motion is then converted into the rotational motion of the antenna mounting plate via a rotary sleeve, achieving stepless and precise adjustment of the horn antenna's elevation angle.

[0057] In summary, the embodiments of this specification provide a horn antenna angle adjustment device that achieves stepless adjustment of the antenna elevation angle, reduces the difficulty of angle adjustment, and improves the overall stability of the device.
