Description

Technical Field

[0001] This utility model relates to the field of antenna assembly technology, specifically to a horn antenna clamping device. Background Technology

[0002] Antenna assembly, as a core component of wireless communication and sensing systems, hinges on achieving efficient signal transmission and reception and precise pointing. With the introduction of laser ranging technology, the system can dynamically adjust the antenna attitude by measuring the target distance and azimuth in real time, thereby maintaining a stable communication link in complex environments (such as mobile platforms or obstacle-blocked scenarios). The scanning frame, as a mechanical carrier, must possess multi-degree-of-freedom motion capabilities (such as azimuth-pitch dual-axis rotation) and a high-rigidity structure to support the antenna's rapid response to positional deviations from laser ranging feedback. Against this backdrop, horn antennas, due to their unique electromagnetic characteristics, become a key component: their gradient waveguide structure effectively suppresses sidelobe interference and provides high-gain, narrow-beam directional radiation capabilities, making them particularly suitable for microwave and millimeter-wave bands (such as 5G base stations, satellite communications, and radar systems).

[0003] However, the strong directivity of horn antennas also places stringent requirements on their pointing accuracy, necessitating integration onto a scanning frame and combining it with the dynamic calibration function of laser ranging to achieve automated target tracking. Existing horn antennas or probes have flat panel structures or connecting flanges. Flat panel structures are difficult to install; connecting flanges come in two types, round and square, and their installation is cumbersome and inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a horn antenna clamping device that can stably clamp horn antennas or probes of different shapes and sizes, and is easy to use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A horn antenna clamping device includes a scanning frame and a mounting plate. The mounting plate has two parallel guide grooves and two parallel sliding members. Each sliding member is slidably connected to the two guide grooves. Each sliding member has a locking structure for fixing it at any position within the guide groove. Each sliding member also has a mounting groove perpendicular to the guide grooves. All mounting grooves are located in the same plane. Its function is to allow the left and right ends of a connecting plate or connecting flange on the horn antenna to be inserted into the mounting grooves on the two sliding members, and to secure the sliding members in their position on the guide grooves using the locking structure after clamping the horn antenna.

[0007] Furthermore, the sliding component includes a straight plate and a U-shaped plate, which, when combined, form a mounting groove. The straight plate and the U-shaped plate are fixedly connected by bolts. Its function is to allow the sliding component to move through the straight plate and the U-shaped plate...

[0008] The design of the sliding component, which is assembled by bolts, allows the height of the mounting groove to be adjusted by changing the distance between the straight plate and the U-shaped plate, thus enabling the mounting groove to adapt to plates or connecting flanges of different thicknesses.

[0009] Furthermore, the U-shaped plate and the straight plate are arranged sequentially along the laser emission direction. The straight plate has multiple mounting holes evenly spaced along its length, each communicating with a mounting groove. The purpose of these mounting holes is to align them with the through holes on the connecting flange, allowing mounting bolts to pass through the corresponding mounting holes and through holes, and mounting nuts to be tightened onto the mounting bolts, thus completing the installation of the horn antenna with the connecting flange.

[0010] Furthermore, it also includes a connecting plate for simultaneous connection with two straight plates. The connecting plate has at least one slot and is perpendicular to both straight plates. Each straight plate has at least one mounting hole located within a slot. Its function is to allow the connecting plate to be fixed to the two straight plates by passing mounting bolts through the mounting holes and slots, enabling the connecting plate to move along the length of the slots on the straight plates. When at least one through hole on the circular connecting flange corresponds to a slot, the rotation angle of the circular connecting flange can be fixed by passing connecting bolts through the slot and the through hole on the circular connecting flange.

[0011] Furthermore, the locking structure includes a locking bolt that passes through the guide groove and is threadedly connected to the sliding member. The outer diameter of the locking bolt's shank is smaller than the width of the guide groove, and the outer diameter of the inscribed circle of the locking bolt's head is larger than the width of the guide groove. The mounting plate has fixing holes evenly distributed along the extension direction of the guide groove, and the straight plate has threaded holes corresponding to the fixing holes. Through the fixing holes and threaded holes, bolts can be threaded through the fixing holes to connect with the threaded holes, further securing the sliding member. Its function is to lock the position of the sliding member by using the locking bolt.

[0012] Furthermore, a washer is provided between the head of the locking bolt and the top surface of the mounting plate, and the outer diameter of the washer is larger than the outer diameter of the circumscribed circle of the head of the locking bolt.

[0013] Furthermore, the scanning frame includes a fixed base plate and a support column, with the support column connecting the fixed base plate and the mounting plate, and the fixed base plate and the mounting plate being arranged parallel to each other. The fixed base plate is in the shape of a circular flange.

[0014] Furthermore, there are multiple support columns, and the support columns are evenly distributed in a ring around the space formed by the guide groove outside the guide groove, and multiple connection holes are provided on the fixed base plate.

[0015] Furthermore, the scanning frame is equipped with a laser rangefinder, which has a laser channel for the laser to pass through. All mounting slots are located in the same plane perpendicular to the laser channel. The scanning frame is equipped with a laser rangefinder bracket for connecting the laser rangefinder. The laser rangefinder bracket includes a support surface and a mounting surface that are perpendicular to each other. The support surface is parallel to the fixed base plate, and the laser rangefinder is connected to the mounting surface. Its function is...

[0016] Therefore, by setting up a laser rangefinder bracket, the laser rangefinder can be installed on the scanning frame.

[0017] Furthermore, at least one support column is provided through the support surface, and at least two through holes corresponding to the connection holes are provided on the support surface.

[0018] The beneficial effects of this utility model are:

[0019] 1. By setting up guide grooves, sliding parts and mounting grooves, the left and right ends of the connecting plate or connecting flange on the horn antenna can be respectively installed into the mounting grooves on the two sliding parts, and the two sliding parts clamp the horn antenna and then the locking structure fixes the position of the sliding parts on the guide groove.

[0020] 2. By setting the mounting holes, the mounting holes can be aligned with the through holes on the connecting flange. Then, the mounting bolts are passed through the corresponding mounting holes and through holes, and the mounting nuts are tightened on the mounting bolts to complete the installation of the horn antenna with the connecting flange.
