Description

Technical Field

[0001] The present application relates to the technical field of antenna bases, and in particular to an antenna base that is easy to adjust its orientation. Background Art

[0002] The satellite receiving antenna is usually installed on a base. The azimuth, pitch angle and other parameters are adjusted according to the position of the signal satellite. After the received signal is clear and stable, the satellite receiving antenna is fixed. A fixed satellite receiving antenna can only receive signals sent by a specific satellite. If you want to receive signals from other satellites, you need to readjust the azimuth, pitch angle and other parameters of the satellite antenna.

[0003] Currently, most antenna bases use a steel ball plate design. In actual use, since the antenna head is heavy, the center offset of the antenna head after pitching to a certain angle will increase the friction at the steel ball plate and cause interference, resulting in difficulty in rotating the antenna in azimuth. Utility Model Content

[0004] In order to facilitate the rotation of the antenna azimuth, the present application provides an antenna base that is easy to adjust the azimuth.

[0005] The present application provides an antenna base that is easy to adjust the orientation and adopts the following technical solution:

[0006] An antenna base that is convenient for adjusting the orientation, comprising:

[0007] A fixed seat, a fixed cylinder is fixedly connected to the fixed seat, a fixed shaft is fixedly connected to the fixed cylinder, and a first limiting piece is fixedly connected to the fixed seat;

[0008] A rotating seat, a first bearing is installed between the rotating seat and the fixed cylinder, a second bearing is installed between the rotating seat and the fixed shaft, an avoidance hole for the fixed shaft to pass through is opened on the rotating seat, and a second limit plate is fixedly connected to the rotating seat;

[0009] The retaining assembly is used to fix the first limiting piece and the second limiting piece.

[0010] By adopting the above technical solution, the antenna head is rotated to the desired position through the rotating seat, and the fixed seat and the rotating seat are fixed by the retaining assembly, so that the antenna head is fixed in the desired orientation. The cooperation between the first bearing and the second bearing can improve the rigidity and strength of the structure, and at the same time improve the coaxiality of the antenna head during the rotation process; when the antenna is at a large pitch angle, the interference caused by the center offset of the antenna head is reduced, thereby facilitating the rotation of the antenna orientation.

[0011] Optionally, the outer wall of the fixing seat is fixedly connected to the limiting seat, a sliding groove is provided on the surface of the limiting seat facing the fixing seat, and the retaining component is arranged in the sliding groove;

[0012] The retaining assembly includes a pressing plate and a bidirectional screw. Two pressing plates are provided. One end of each of the two pressing plates extends into the slide groove. The other ends of the two pressing plates are used to fix the first limiting plate and the second limiting plate. The bidirectional screw is rotatably connected in the slide groove of the limiting seat. The bidirectional screw passes through the two pressing plates. The bidirectional screw is threadedly connected to the pressing plates.

[0013] The limiting seat is fixedly connected with a guide rod in the slide groove, and the guide rod penetrates the pressing plate and the two are slidably fitted.

[0014] With the above technical solution, the two-way screw rotates to bring the two pressure plates closer to each other until the two pressure plates press against the first limit plate and the second limit plate, thereby fixing the first limit plate and the second limit plate; the two-way screw rotates in the opposite direction to move the two pressure plates away from each other, thereby releasing the first limit plate and the second limit plate. The pressure plate slides along the guide rod during the movement, and the guide rod guides and limits the pressure plate.

[0015] Optionally, one end of the bidirectional lead screw passes through the limit seat and extends to the outside, the end of the bidirectional lead screw extending from the limit seat is fixedly connected to a driven gear, a drive motor is installed on the outer wall of the fixed seat, and the output shaft of the drive motor is fixedly connected to a driving gear meshing with the driven gear.

[0016] By adopting the above technical solution, after the driving motor is started, the bidirectional lead screw is rotated through the driving gear and the driven gear, so that the pressing plate is moved by electronic control, thereby reducing the labor intensity of manual labor.

[0017] Optionally, a fixed plate is fixedly connected to the limit seat, and a threaded sleeve is rotatably connected to the side of the fixed plate facing away from the rotating seat. A one-way screw is slidably connected in the fixed plate, the one-way screw passes through the threaded sleeve and the two are threadedly connected, and a support plate is fixedly connected to the end of the one-way screw away from the threaded sleeve, and the support plate is used to tighten the rotating seat.

[0018] With the above technical solution, the threaded sleeve rotates to make the one-way screw approach the rotating seat until the support plate presses against the rotating seat; the threaded sleeve rotates in the opposite direction to make the one-way screw carry the rotating seat, thereby moving the support plate away from the rotating seat. When the pressure plate fixes the first limiting plate and the second limiting plate, the support plate presses against the rotating seat, thereby improving the stability of the rotating seat.

[0019] Optionally, one end of the bidirectional lead screw close to the unidirectional lead screw passes through the limit seat and extends to the outside, and one end of the bidirectional lead screw extending from the limit seat is fixedly connected to a driving bevel gear, and a driven bevel gear meshing with the driving bevel gear is fixedly connected to the threaded sleeve.

[0020] By adopting the above technical solution, when the bidirectional lead screw rotates, the bidirectional lead screw rotates through the active bevel gear and the driven bevel gear, thereby achieving the effect that the bidirectional lead screw drives the unidirectional lead screw to rotate.

[0021] Optionally, a through hole is formed in the fixing plate for the one-way screw to pass through, the fixing plate is fixedly connected to a limiting block in the through hole, and a limiting groove is formed on the outer wall of the one-way screw to slideably match the limiting block.

[0022] By adopting the above technical solution, when the one-way screw is moving, the limit block slides in the limit groove, so that the limit block makes it difficult for the one-way screw to rotate with the one-way screw, thereby achieving the effect of guiding and limiting the one-way screw.

[0023] Optionally, anti-slip pads are fixedly connected to the opposite side surfaces of the two pressing plates.

[0024] By adopting the above technical solution, when the pressure plate clamps the first limiting plate and the second limiting plate, the anti-slip pad increases the friction between the pressure plate and the first limiting plate, and between the pressure plate and the second limiting plate, thereby improving the stability of the rotating seat.

[0025] Optionally, a surface of the first limiting plate facing the second limiting plate is spherically hinged with a ball, and a surface of the second limiting plate facing the first limiting plate is provided with a rolling groove adapted for rolling of the ball.

[0026] By adopting the above technical solution, during the rotation of the rotating seat, the ball reduces the friction between the first limiting plate and the second limiting plate, thereby improving the smoothness of the rotation of the rotating seat.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The cooperation between the first bearing and the second bearing can improve the rigidity and strength of the structure, and at the same time improve the coaxiality of the antenna head during rotation; when the antenna is at a large pitch angle, the interference caused by the center offset of the antenna head is reduced, thereby facilitating the rotation of the antenna azimuth.

[0029] 2. After the rotating seat rotates the antenna head to the desired position, the drive motor is started to rotate the bidirectional screw, so that the two pressure plates clamp the first limit plate and the second limit plate. When the bidirectional screw rotates, the threaded sleeve is rotated through the active bevel gear and the driven bevel gear, thereby causing the support plate to press the rotating seat tightly, thereby fixing the antenna head in the desired position.
