Description

Technical Field

[0001] The utility model belongs to the technical field of communication disassembly tools, and in particular relates to a high-reliability and convenient disassembly tool suitable for a multi-channel antenna subarray. Background Art

[0002] Multi-channel phased array radar antennas are often integrated using antenna subarrays, each consisting of multiple channels. Furthermore, to achieve miniaturization and high integration of radar antennas, each channel of the antenna subarray is connected to the RF module using vertical blind-plug connectors. These SMP-KK connectors are push-on, snap-on connectors with a certain insertion and removal force. Furthermore, to ensure that the spacing between antenna channel elements remains approximately half a wavelength, the antenna subarrays must be installed tightly together. The gaps between the antenna subarrays are very small, and the combined insertion and removal force of the KK connectors on each channel is very high, making it difficult to disassemble the antenna subarray using conventional tools. Furthermore, antenna subarrays typically have dozens of independent channels, each with its own KK connector insertion and removal force. During disassembly, if the antenna subarray is subjected to uneven force, it can not only damage the connector housing but can also deform the entire antenna subarray structure, seriously affecting antenna performance. Furthermore, since the size and structure of antenna subarrays often vary depending on the array layout requirements, disassembly and replacement of antenna subarrays present certain difficulties and challenges. Therefore, it is necessary to improve the disassembly device of the multi-channel antenna subarray in the prior art and provide a disassembly tool with strong adaptability so that one disassembly tool can complete the disassembly and replacement of antenna subarrays of different forms. Utility Model Content

[0003] The utility model is aimed at the above-mentioned problems and provides a high-reliability and convenient disassembly tool for multi-channel antenna subarrays, which can ensure that the structure of the antenna subarrays is uniformly stressed and avoid affecting the performance of the antenna subarrays. The utility model is suitable for disassembling antenna subarrays with different structural forms, is easy to use, and has strong practicality. It is suitable for disassembly of multi-channel antenna subarrays with high reliability.

[0004] The technical solution adopted by the present invention is: the high-reliability and convenient disassembly tooling suitable for multi-channel antenna subarrays includes a fixed chassis, which is characterized in that: an antenna subarray pick-up and placement opening is provided on the fixed chassis, a supporting beam is provided in the middle of the antenna subarray pick-up and placement opening, and a movable bracket arranged in the longitudinal direction is provided above the supporting beam, and the two ends of the movable bracket are movably connected to the edges of the fixed chassis on both sides of the antenna subarray pick-up and placement opening, and a vertically arranged bracket lifting screw is rotatably provided in the middle of the movable bracket, the upper end of the bracket lifting screw is provided with a rotating lever, and the lower end of the bracket lifting screw is in contact with the upper side of the supporting beam; antenna subarray locking screws with adjustable positions are also vertically provided on both sides of the upper and middle bracket lifting screws of the movable bracket.

[0005] The movable bracket is provided with bracket connection legs at both ends of the bracket body. Positioning latch connection holes are provided at the lower ends of the bracket connection legs. Each of the positioning latch connection holes contains a bracket shift positioning latch. The bracket shift positioning latches position and insert both ends of the movable bracket into a plurality of bracket shift positioning holes provided on either side of the antenna subarray access opening and on the edge of the fixed chassis. The position of the movable bracket can be flexibly changed according to the position of the antenna subarray to be removed at the antenna subarray access opening of the fixed chassis. The bracket shift positioning latches at both ends position and insert the movable bracket into the bracket shift positioning holes at the corresponding positions on the edge of the fixed chassis, thereby facilitating subsequent removal of the antenna subarray.

[0006] The threaded section at the lower end of the bracket lifting screw is rotatably mounted in the lifting screw mounting internal threaded hole in the middle of the mobile bracket, and a lifting screw limiting contact pad is provided at the lower end of the bracket lifting screw passing through the mobile bracket. The lifting screw limiting contact pad is movably mounted in the bracket displacement slide groove on the upper side of the support beam. The upper end of the bracket lifting screw is provided with a twist lever insertion hole, and the rotatable twist lever is inserted into the twist lever insertion hole. The support beam is used to support the lower end of the bracket lifting screw, facilitating the rotation of the bracket lifting screw in the lifting screw mounting internal threaded hole in the middle of the mobile bracket, thereby changing the vertical height of the mobile bracket and the antenna subarray locking screw thereon, thereby achieving disassembly of the antenna subarray. Moreover, when the position of the mobile bracket needs to be changed according to the position of the antenna subarray to be disassembled, the lifting screw limiting contact pad provided at the lower end of the bracket lifting screw cooperates with the bracket displacement slide groove on the upper side of the support beam to guide the repositioning of the mobile bracket.

[0007] The antenna subarray locking screws are rotatably mounted within a plurality of locking screw mounting internal threaded holes arranged on both sides of the central portion of the mobile bracket. A locking screw rotating cap is provided at the upper end of the antenna subarray locking screw, and an antenna subarray mounting hole connecting portion is provided at the lower end of the antenna subarray locking screw. Based on the different sizes of antenna subarrays at the opening for receiving and placing the antenna subarrays on the fixed chassis, the antenna subarray locking screws on both sides are installed within the locking screw mounting internal threaded holes at corresponding width positions on both sides of the lifting screw mounting internal threaded hole in the central portion of the mobile bracket. The antenna subarray mounting hole connecting portions at the lower ends of the antenna subarray locking screws are connected to the existing mounting holes at both ends of the antenna subarray, thereby facilitating the upward lifting and removal of the antenna subarrays during the mobile bracket's ascent.

[0008] The antenna subarray locking screw is also equipped with a locking screw lock nut on the underside of the movable bracket. After the antenna subarray mounting hole connection portion at the lower end of the antenna subarray locking screw is connected to the mounting holes at both ends of the antenna subarray, the locking screw lock nut located below the locking screw's internally threaded mounting hole secures the vertical position of the antenna subarray locking screw, thereby improving the stability of the device.

[0009] The antenna subarray access opening of the fixed chassis is surrounded by several raised steps. Antenna subarray access spaces of varying widths are formed between adjacent raised steps at the same location. This facilitates the alignment of antenna subarrays of varying sizes within the spaces formed between the raised steps. Furthermore, the raised steps effectively enhance the overall strength of the fixed chassis frame structure.

[0010] The underside of the fixed chassis is equipped with chassis stabilizing legs. These legs, located at corresponding positions on the underside of the fixed chassis, adjust the parallelism between the fixed chassis and the antenna subarray to be removed, based on the undulating structure of the antenna supporting structure. This facilitates normal use of the device.

[0011] The beneficial effects of the present invention are as follows: since the present invention adopts a fixed chassis on which an antenna subarray access opening is provided, a supporting beam is provided in the middle of the antenna subarray access opening, and a movable bracket arranged in the longitudinal direction is provided above the supporting beam, and both ends of the movable bracket are movably connected to the edges of the fixed chassis on both sides of the antenna subarray access opening, a bracket lifting screw is rotatably provided in the middle of the movable bracket, a rotating hinge is provided at the upper end of the bracket lifting screw, and the lower end of the bracket lifting screw is in contact with the upper side of the supporting beam, and a position-adjustable antenna subarray locking screw structure is provided on both sides of the upper and middle bracket lifting screws of the movable bracket, so the design is reasonable and the structure is compact, and the mounting hole of the antenna subarray itself can be used as a disassembly locking point, and the required disassembly space is small, and it can be used for compactly installed antenna array surfaces, effectively solving the problem of high-reliability disassembly of compactly installed multi-channel antenna subarrays. During disassembly, the disassembly tool lifts the multi-channel antenna subarray as a whole, ensuring it rises upward. This uniformly distributes force across the antenna subarray structure, preventing deformation and component damage, thus ensuring its electrical performance. Furthermore, the tool is adaptable to antenna subarrays of varying sizes, allowing for the removal of antenna subarrays of varying sizes with a single tool, demonstrating its high adaptability. Furthermore, the tool is compact and portable, making it easy to use, reliable, and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] according to Figures 1 to 8The specific structure of the present invention is described in detail. The high-reliability and convenient disassembly tool suitable for multi-channel antenna subarrays includes a fixed chassis 1 of a frame structure, and an antenna subarray access opening 2 is provided in the middle of the fixed chassis 1. A number of raised steps 10 are provided around the antenna subarray access opening 2; and antenna subarray access spaces of different widths are formed between two adjacent raised steps 10 at the same position; and then antenna subarrays 23 of different sizes are aligned to the antenna subarray access spaces of different widths formed between the raised steps 10, which facilitates the alignment and placement of antenna subarrays 23 of different sizes; at the same time, the provision of the raised steps 10 also effectively improves the overall strength of the fixed chassis 1 of the frame structure. A chassis stabilizing foot 11 is also provided on the lower side of the edge of the fixed chassis 1, so that the parallel posture between the fixed chassis 1 and the antenna subarray to be disassembled can be adjusted according to the high and low undulating structure of the upper side of the antenna supporting structure 22 for supporting the antenna subarray, through the chassis stabilizing foot 11 provided at the corresponding position on the lower side of the fixed chassis 1, so as to facilitate the normal use of the device.

[0022] A support beam 3 is fixedly mounted in the middle of the antenna subarray access opening 2 of the fixed chassis 1. A longitudinally arranged mobile bracket 5 is positioned above the support beam 3, extending perpendicularly to the direction of extension of the support beam 3 in the horizontal plane. Furthermore, each end of the mobile bracket 5 is provided with bracket connection legs 16. Positioning pin holes 17 are provided at the lower ends of the bracket connection legs 16, and bracket shift positioning pins 13 are disposed within each positioning pin hole 17. The two ends of the mobile bracket 5 are positioned and plugged into a plurality of bracket shift positioning holes 9 provided on either side of the antenna subarray access opening 2 and along the edge of the fixed chassis 1 via the bracket shift positioning pins 13. Thus, the position of the mobile bracket 5 can be flexibly changed according to the different positions of the antenna subarray to be disassembled at the antenna subarray access opening 2 of the fixed chassis 1, and the bracket shift positioning pins 13 at both ends are used to position the mobile bracket 5 and insert it into the bracket shift positioning hole 9 at the corresponding position at the edge of the fixed chassis 1, so as to facilitate the subsequent disassembly of the antenna subarray.

[0023] A vertically arranged support lifting screw 7 is rotatably mounted within the internal threaded hole 14 for mounting the lifting screw in the middle of the mobile support 5. The threaded section at the bottom of the support lifting screw 7 is rotatably connected to the internal threaded hole 14 for mounting the lifting screw in the middle of the mobile support 5. The support lifting screw 7 passes through the lower end of the mobile support 5 and is provided with a lifting screw limiting contact pad 12. The lifting screw limiting contact pad 12 is movably mounted within the support shifting slot 4 on the upper side of the support beam 3. A twist lever insertion hole 18 is provided at the upper end of the support lifting screw 7, into which a rotating twist lever 8 is inserted. The support beam 3 then supports the lower end of the support lifting screw 7, facilitating the rotation of the support lifting screw 7 within the internal threaded hole 14 for mounting the lifting screw in the middle of the mobile support 5, thereby changing the vertical height of the mobile support 5 and the antenna subarray locking screw 6 thereon, thereby enabling disassembly of the antenna subarray. Moreover, when the position of the mobile bracket 5 needs to be changed according to the position of the antenna sub-array to be disassembled, the lifting screw limit contact pad 12 set at the lower end of the bracket lifting screw 7 cooperates with the bracket shifting slide groove 4 on the upper side of the supporting beam 3 to guide the repositioning of the mobile bracket 5.

[0024] Adjustable antenna subarray locking screws 6 are vertically mounted on the left and right sides of the upper and middle bracket lifting screws 7 of the mobile bracket 5. The two antenna subarray locking screws 6 are rotatably mounted within a plurality of sets of internally threaded locking screw mounting holes 15 symmetrically arranged on either side of the middle portion of the mobile bracket 5. The upper ends of the antenna subarray locking screws 6 are provided with locking screw rotating caps 19 for tightening the locking screws, while the lower ends of the antenna subarray locking screws 6 are provided with antenna subarray mounting hole connectors 21 for connecting to the mounting holes at either end of the antenna subarray. Furthermore, locking screw lock nuts 20 are located on the rods of the antenna subarray locking screws 6, located below the mobile bracket 5. Furthermore, based on the different sizes of the antenna subarrays at the antenna subarray access opening 2 of the fixed chassis 1, the antenna subarray locking screws 6 on both sides are installed in the locking screw mounting internal threaded holes 15 at corresponding width positions on both sides of the lifting screw mounting internal threaded hole 14 in the middle of the mobile bracket 5. The antenna subarray mounting hole connecting portion 21 at the lower end of the antenna subarray locking screw 6 is connected to the existing mounting holes at both ends of the antenna subarray, so that the antenna subarray can be lifted and disassembled upward during the ascending process of the mobile bracket 5. In addition, after the antenna subarray mounting hole connecting portion 21 at the lower end of the antenna subarray locking screw 6 is connected to the mounting holes at both ends of the antenna subarray, the vertical position of the antenna subarray locking screw 6 is fixed by the locking screw locking nut 20 located on the lower side of the locking screw mounting internal threaded hole 15, thereby improving the stability of the lifting device.

[0025] To use this highly reliable and convenient disassembly tool for multi-channel antenna subarrays, first place the fixed chassis 1 on the antenna supporting structure 22 where the antenna subarrays are located. The disassembly tool is then secured in place by engaging the chassis stabilizing feet 11 on the underside of the fixed chassis 1 with the edges of the antenna supporting structure 22. Next, the bracket lifting screw 7 is rotated and installed within the lifting screw mounting internal threaded hole 14 in the middle of the movable bracket 5. The lifting screw limit contact pad 12 at the lower end of the bracket lifting screw 7 contacts the bracket shifting slot 4 on the upper side of the supporting crossbeam 3, serving as a support point for the subsequent pulling of the antenna subarray by the movable bracket 5. Subsequently, according to the position of the antenna sub-array to be disassembled, the bracket shift positioning holes 9 at appropriate positions on both sides of the fixed chassis 1 are selected, and the bracket shift positioning pins 13 on the lower side of the bracket connecting legs 16 at both ends of the mobile bracket 5 are plugged into the bracket shift positioning holes 9 at corresponding positions to fix the position of the mobile bracket 5 in the plane of the fixed chassis 1 (the bracket can also be freely lifted and lowered in the axial direction of the vertically arranged bracket lifting screw 7).

[0026] Then, based on the lengths of antenna subarrays 23 of different sizes on the antenna supporting structure 22, the locking screw mounting internal threaded holes 15 at appropriate positions on the mobile bracket 5 are selected, and the two antenna subarray locking screws 6 are passed through the selected locking screw mounting internal threaded holes 15. The antenna subarray locking screws 6 are then rotated to adjust their heights so that the antenna subarray mounting hole connecting portions 21 at the lower ends of the antenna subarray locking screws 6 are respectively locked and connected with the mounting holes at both ends of the antenna subarray to be removed. At the same time, the locking screw locking nuts 20 on the antenna subarray locking screws 6 located on the lower side of the mobile bracket 5 (locking screw mounting internal threaded holes 15) enhance the locking effect, thereby preventing the mobile bracket 5 from pulling out the antenna subarray due to thread damage, thereby improving the stability of the device. Afterwards, the rotating lever 8 is inserted into the lever insertion hole 18 at the upper end of the bracket lifting screw 7, and power is input by rotating the rotating lever 8, so that the bracket lifting screw 7 rotates in the lifting screw mounting internal threaded hole 14 in the middle of the mobile bracket 5, so as to realize the smooth rise of the mobile bracket 5 relative to the fixed chassis 1 and the antenna supporting structure 22 below it. In the process of the mobile bracket 5 moving upward, the antenna subarray locked and connected to the lower ends of the two antenna subarray locking screws 6 will also rise synchronously until the antenna subarray is separated from the connector, thereby realizing the reliable disassembly of the antenna subarray; the overall force of the antenna subarray assembly is uniform and the structure is not deformed, ensuring that the electrical performance of the antenna subarray is not affected by the disassembly process.
