Description

Technical Field

[0001] The present application relates to the technical field of antenna bases, and in particular to an adjustable antenna base. Background Art

[0002] An antenna is a converter that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or performs the opposite conversion. It is a component used to transmit or receive electromagnetic waves in radio equipment. Engineering systems such as broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, all of which use electromagnetic waves to transmit information, rely on antennas to work. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna.

[0003] The antenna needs to be installed on a base, and the elevation angle of the antenna needs to be adjusted during use. Currently, most existing bases are fixed, which has the defect of being inconvenient to adjust the elevation angle of the antenna. Utility Model Content

[0004] In order to facilitate the adjustment of the pitch angle of the antenna, the present application provides an adjustable antenna base.

[0005] The present application provides an adjustable antenna base adopting the following technical solution:

[0006] An adjustable antenna base, comprising:

[0007] The column includes a fixed part and an adjusting part, the fixed part is fixed to the ground, the adjusting part is ball-hinged with the fixed part, both sides of the fixed part are connected with fixed plates, an adjusting rod is slidably connected in the fixed plate, and one end of the adjusting rod is used to squeeze the adjusting part;

[0008] The positioning assembly comprises a moving unit and a rotating unit. The moving unit is used to drive the adjusting rod to slide in the fixed plate, and the rotating unit is used to drive the fixed plate to rotate around the column.

[0009] By adopting the above technical solution, the position of the adjustment rod in the fixed plate is changed by the moving unit, thereby changing the degree of compression of the adjustment rod on the adjustment part, thereby changing the pitch angle of the antenna in a straight line, and the position of the adjustment rod in the plane is changed by the rotating unit, thereby changing the pitch angle of the antenna in the entire plane; after the adjustment is completed, the two adjustment rods are pressed against the adjustment part, so that the adjustment part remains stable. The above operation method is simple and fast, and achieves the effect of facilitating the adjustment of the antenna pitch angle.

[0010] Optionally, the moving unit includes a sleeve and a first motor, the sleeve is threadedly connected to the adjusting rod, the sleeve is rotatably connected to the fixed plate, a driven bevel gear is fixedly connected to the sleeve, the first motor is installed on the fixed plate, the two first motors have opposite directions, and an active bevel gear meshing with the driven bevel gear is fixedly connected to the output shaft of the first motor.

[0011] With the above technical solution, the first motor is started to rotate the screw sleeve through the active bevel gear and the driven bevel gear, so that the adjustment rod slides in the fixed plate. The position of the adjustment rod in the fixed plate is controlled by the first motor to improve the control accuracy; the two first motors are started at the same time to rotate the two screw sleeves at the same time, so as to adjust the positions of the two adjustment rods at the same time.

[0012] Optionally, the fixing plate is provided with a through hole for the adjusting rod to pass through, a limiting block is fixedly provided in the through hole of the fixing plate, and a limiting groove which is slidably matched with the limiting block is provided on the outer wall of the adjusting rod.

[0013] By adopting the above technical solution, when the screw sleeve rotates, the adjusting rod moves to make the limit block slide in the limit groove, so that the adjusting rod is not easy to rotate with the screw sleeve, thereby achieving the effect of guiding the adjusting rod.

[0014] Optionally, the rotating unit includes a turntable and a second motor, the turntable is sleeved on the fixed part and the two are rotatably connected, the turntable is fixedly provided with a driving ring gear, the second motor is mounted on the fixed part, and the output shaft of the second motor is fixedly connected with a driving gear that meshes with the driving ring gear.

[0015] By adopting the above technical solution, the second motor is started to rotate the turntable through the driving gear and the driving ring gear, so that the turntable causes the fixed plate to rotate around the central axis of the column, thereby changing the position of the adjustment rod in the plane.

[0016] Optionally, one end of the adjusting rod close to the adjusting portion is rotatably connected to a ball, and the ball is tightly pressed against the adjusting portion.

[0017] By adopting the above technical solution, when the rotating unit changes the position of the adjusting rod in a plane, the friction between the adjusting rod and the fixed part is replaced by rolling friction from sliding friction, thereby reducing the friction between the adjusting rod and the adjusting part, thereby making the adjusting rod rotate smoothly around the column.

[0018] Optionally, the outer wall of the fixing portion is detachably connected to a support rod, a plurality of support rods are provided, and the plurality of support rods are spaced apart around a central axis of the fixing portion, and a diagonal brace is detachably connected between the support rod and the fixing portion.

[0019] By adopting the above technical solution, the fixing part is stabilized by the support rods and the diagonal braces, thereby improving the stability of the fixing part. At the same time, the support rods and the diagonal braces are arranged to be detachably connected, thereby reducing the occupied area during transportation.

[0020] Optionally, a stabilizing block is fixedly disposed at one end of the support rod away from the fixing portion, and a stabilizing screw is threadedly connected to the inner thread of the stabilizing block.

[0021] By adopting the above technical solution, the stability of the support rod is further enhanced by connecting the stabilizing screw rod and the stabilizing block to the ground, thereby further enhancing the stability of the fixing part.

[0022] Optionally, one end of the stabilizing screw is fixedly connected to a handwheel.

[0023] By adopting the above technical solution, it is convenient for workers to rotate the stabilizing screw rod through the hand wheel.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The screw sleeve rotates to make the adjustment rod slide in the through hole, thereby changing the position of the adjustment rod in the fixed plate, thereby changing the degree of compression of the adjustment rod on the adjustment part, and changing the position of the adjustment rod in the plane by the turntable, thereby being able to adjust the degree of compression of a circle around the adjustment part, thereby changing the pitch angle of the antenna in the entire plane, achieving the effect of facilitating the adjustment of the antenna pitch angle.

[0026] 2. The fixed part is stabilized by the support rod and the diagonal brace, and the stability of the support rod is further enhanced by connecting the stabilizing screw and the stabilizing block to the ground. In the above manner, the stability of the fixed part is improved, thereby improving the stability of the antenna. BRIEF DESCRIPTION OF THE DRAWINGS
