Description

Technical Field

[0001] The present application relates to the technical field of antennas, and in particular to a portable antenna device. Background Art

[0002] An antenna is a transducer that converts guided waves propagating along a transmission line into electromagnetic waves propagating through an unbounded medium. Antennas are generally reversible, meaning the same antenna can function as both a transmitting and receiving antenna. Wireless devices in everyday life, such as communications, radar, navigation, broadcasting, and television, all rely on radio waves to transmit information. These devices are required to both radiate and receive these waves, and therefore, antennas are widely used in various applications.

[0003] As people's requirements for antenna performance become higher and higher, the application of antenna testing is becoming more and more extensive. Traditional antenna testing is to manually adjust the perpendicularity of the two axes of the antenna body and the detection device. Due to the large size of the antenna device, manual movement will cause a large error in the perpendicularity of the two axes, making detection difficult, resulting in low accuracy of antenna radiation index testing and distortion of the antenna pattern. Summary of the Invention

[0004] In order to improve the accuracy of antenna detection, the present application provides a portable antenna device.

[0005] This application provides a portable antenna device, which adopts the following technical solution:

[0006] A portable antenna device includes a back frame, a plurality of clamping members are provided in the middle of the back frame, and the plurality of clamping members are used to fix the antenna body. An adjustment support frame is installed on one side of the back frame, and a detection mechanism is provided between the adjustment support frame and the back frame. The detection mechanism includes a detection member, which is slidably installed between the opposite sides of two adjacent clamping members, and the detection end of the detection member abuts against the side wall of the antenna body. A moving mechanism is provided in the middle of the adjustment support frame, and the moving mechanism is used to move and position the detection member.

[0007] By adopting the above technical solution, the antenna body can be fixed under the action of several clamping parts, reducing the steps of manually adjusting the position of the antenna body and the central axis of the back frame, thereby improving the positioning accuracy of the antenna body, and adjusting the support frame to provide support for the moving mechanism. The moving mechanism can move and position the detection part as a power source, so that the detection part can easily detect various sections of the antenna body, effectively improving the efficiency and accuracy of antenna detection.

[0008] Preferably, the moving mechanism includes: movable slide rails respectively installed on the two long sides of the adjustment support frame; a movable seat slidably connected to the movable slide rails; a transmission shaft rotatably connected to the bottom wall of the movable seat; a transmission gear fixed in the middle of the transmission shaft; a rack fixed between the two movable slide rails; a driving member assembled at one end of the transmission shaft; and a positioning assembly arranged on the top of the movable seat, wherein the transmission gear is meshed with the rack, and the extension direction of the movable slide rail is consistent with the extension direction of the central axis of the antenna body.

[0009] By adopting the above technical solution, under the action of the driving member, the transmission gear can rotate, that is, the transmission gear can roll along the direction of the rack. At the same time, the movable seat can move along the movable slide rail, thereby achieving progressive advancement along the extension direction of the central axis of the antenna body, which is beneficial to control the position of the positioning component, thereby improving the detection efficiency and accuracy of the detection member on the antenna body.

[0010] Preferably, the positioning assembly includes: a second slide rail respectively installed on the two long sides of the movable seat; a first slide rail opened on both sides opposite to the two adjacent clamping members; a mounting seat slidably connected to the second slide rail; a first cylinder arranged on the movable seat and assembled with the mounting seat; and a detection drive assembly arranged on the mounting seat, wherein the first slide rail and the second slide rail are arranged opposite to each other.

[0011] By adopting the above technical solution, under the action of the first cylinder, the mounting seat can move along the second slide rail. By arranging the first slide rail and the second slide rail opposite each other, the mounting seat can be easily transitioned from the second slide rail to the first slide rail, thereby improving the positioning accuracy of the detection drive assembly and enabling the detection piece to easily abut against the antenna body.

[0012] Preferably, the detection drive assembly includes: movable guide rails respectively installed on the two long sides of the mounting seat; and a second cylinder installed on the mounting seat and assembled with the detection member, wherein the detection member is slidably connected to the movable guide rails.

When the detection end of the detection piece is in a non-contact state with the antenna body, the second cylinder stops moving, and the detection piece stays at a specific abnormal point position on the movable guide rail, allowing staff to easily track the corresponding position of the antenna body, thereby improving the accuracy of antenna detection.

[0018] Preferably, the clamping assembly includes a sliding portion, which is arranged in the middle position of the adjusting rod, and a moving block is slidably connected to the sliding portion. A reset spring is connected between the moving block and the pressing block, and the side of the moving block close to the antenna body is in contact with the side wall of the antenna body.

[0019] By adopting the above technical solution, the return spring is connected between the moving block and the pressing block. By rotating the adjusting rod, the two abutting blocks move closer to each other. Under the action of the return spring, the moving block can move on the sliding part. The return spring is compressed, and one side of the moving block presses against the side wall of the antenna body, so that the antenna body can be stably locked between the two moving blocks, which can improve the positioning accuracy of the antenna body. In addition, the setting of the return spring can form a soft connection between the moving block and the pressing block, which helps to extend the service life of the clamping assembly.

[0020] Preferably, one end of the adjusting rod extends out of the clamping member, and an adjusting handle is installed on the portion of the adjusting rod extending out of the clamping member.

[0021] By adopting the above technical solution and setting the adjustment handle, the staff can easily rotate the adjustment rod.

[0022] Preferably, a positioning groove is provided on the bottom wall of the back frame, a stopping groove is provided on the top wall of the back frame, and the antenna body is movably engaged between the positioning groove and the stopping groove.

[0027] The antenna body can be fixed under the action of several clamping parts, reducing the steps of manually adjusting the position of the antenna body and the central axis of the back frame, thereby improving the positioning accuracy of the antenna body. The adjustment support frame provides support for the moving mechanism. The moving mechanism acts as a power source to move and position the detection part, allowing the detection part to easily detect various sections of the antenna body, effectively improving the efficiency and accuracy of antenna detection.

[0028] The return spring is connected between the moving block and the pressing block. By rotating the adjusting rod, the two abutting blocks move closer to each other. Under the action of the return spring, the moving block can move on the sliding part. The return spring is compressed, and one side of the moving block presses against the side wall of the antenna body, so that the antenna body can be stably locked between the two moving blocks, which can improve the positioning accuracy of the antenna body. In addition, the setting of the return spring can form a soft connection between the moving block and the pressing block, which helps to extend the service life of the clamping assembly.

[0037] More specifically, refer to Figure 1 and Figure 4A positive thread portion 2311 is provided at one end of the adjusting rod 231, and a reverse thread portion 2312 is provided at the other end. A pressing block 2314 is provided on both the positive thread portion 2311 and the reverse thread portion 2312 of the adjusting rod 231. In the embodiment of the present application, there are two pressing blocks 2314 on a clamping member 23, one pressing block 2314 is threadedly connected to the positive thread portion 2311, and the other pressing block 2314 is threadedly connected to the reverse thread portion 2312.

[0040] Reference Figure 2 An adjustment support frame 31 is installed on one side of the back frame 2. In the embodiment of the present application, movable slide rails 312 are installed on the two long sides of the adjustment support frame 31. The extension direction of the movable slide rail 312 is consistent with the extension direction of the central axis of the antenna body 1. A movable seat 311 is slidably connected to the movable slide rail 312, and a transmission shaft (not shown in the figure) is rotatably connected to the bottom wall of the movable seat 311. A transmission gear (not shown in the figure) is fixed to the middle of the transmission shaft. In addition, a rack 313 is fixed between the two movable slide rails 312. The extension direction of the rack 313 is consistent with the extension direction of the movable slide rail 312. The transmission gear is meshed with the rack 313, and a drive motor (not shown in the figure) is assembled at one end of the movable seat 311 close to the transmission shaft.

[0041] Under the action of the driving motor, the transmission shaft can rotate, so that the transmission gear can roll along the rack 313 , so that the moving seat 311 can move along the two moving slide rails 312 .

[0042] Reference Figure 1 and Figure 3 , second slide rails 322 are installed on the two long sides of the movable seat 311, and correspondingly, first slide rails 321 are opened on both sides facing the two adjacent clamping members 23, the first slide rails 321 and the second slide rails 322 are arranged opposite each other, and the extension direction of the second slide rail 322 is perpendicular to the extension direction of the movable slide rail 312, and the second slide rail 322 is slidably connected to the mounting seat 324, and the first cylinder 323 is fixed on the movable seat 311, and the output end of the first cylinder 323 is assembled with the side wall of the mounting seat 324.

[0043] In addition, movable guide rails 3251 are respectively installed on the two long sides of the mounting seat 324. The extension direction of the movable guide rails 3251 is consistent with the extension direction of the movable slide rail 312.

[0044] Under the action of the first cylinder 323, the mounting seat 324 can move along the second slide rail 322, so that the mounting seat 324 can move closer to the antenna body 1, so that the detection end of the detection member 42 is in contact with the side wall of the antenna body 1, that is, the lateral position of the phase center of the antenna body 1 is projected onto the detection end of the detection member 42.

The two moving blocks 2316 are pressed against the side wall of the antenna body 1 at the same time, which can fix and align the antenna body 1.

[0048] Under the action of the first cylinder 323, the mounting seat 324 body moves along the second slide rail 322 toward the antenna body 1, and the detection end of the detection piece 42 can abut against the side wall of the antenna body 1. Under the action of the second cylinder 3252, the detection piece 42 moves along the movable guide rail 3251. When the detection end of the detection piece 42 is in a non-contact state with the antenna body 1, the detection piece 42 feeds back information to the alarm 43 and sounds an alarm. The second cylinder 3252 stops moving and records the distance moved by the detection piece 42 on the movable guide rail 3251.

[0049] After completing the inspection of a section of the antenna body 1, under the action of the second cylinder 3252, the detection part 42 returns to the zero scale position of the measuring part 41 along the movable guide rail 3251. Under the action of the first cylinder 323, the mounting seat 324 moves away from the antenna body 1 along the second slide rail 322.
