AI Technical Summary
In the existing technology, radar antenna brackets are prone to vibration under wind force, which can cause expansion bolts to loosen, affecting the positioning stability of the bracket and thus the stability of the radar antenna.
The reinforcement structure consists of four fixed rods and a reinforcing mechanism, including a round tube, a round rod, a fixed plate, a clamping rod, a counterweight, and a rubber ring. The round rod and the round tube are fixed with nuts, and the movement of the round rod and the round tube is restricted by the clamping rod, the counterweight, and the rubber ring, thereby enhancing the fixing stability of the expansion bolt.
This effectively prevents the expansion bolts from rotating horizontally and moving longitudinally during the fixing process, improving the installation stability of the radar antenna bracket and avoiding offset during use.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of radar antenna bracket positioning technology, and in particular to a radar antenna bracket positioning mechanism for preventing displacement. Background Technology
[0002] Radar is an electronic device that uses electromagnetic waves to detect targets. By emitting electromagnetic waves and receiving the echoes reflected from the targets, it can detect, locate, measure speed, and identify targets. The radar antenna is the core component of a radar system, responsible for emitting and receiving electromagnetic waves and determining the detection direction. The radar antenna bracket is a core component for installing radar equipment. To ensure the accuracy of signal reception and transmission during use, the radar antenna is mounted and secured using a bracket.
[0003] Currently, in existing technologies, rigid brackets are typically used to install radar antennas outdoors, and expansion bolts are used to fix the brackets to the ground. However, during the fixing process, the brackets are prone to vibration under the action of wind, and the force of the vibration is transmitted to the expansion bolts. The expansion bolts are prone to loosening under the action of vibration, which reduces the stability of the radar antenna bracket positioning and makes the radar antenna bracket prone to displacement, thus affecting the stability of the radar antenna during use. Utility Model Content
[0004] Therefore, it is necessary to provide a radar antenna bracket positioning mechanism to address the problem that expansion bolts are prone to loosening under vibration during the fixing process, which reduces the stability of the radar antenna bracket positioning and makes the radar antenna bracket prone to displacement, thus affecting the stability of the radar antenna during use.
[0005] Includes: four fixing rods respectively fixedly connected to the four corners of the bottom end of the bracket, the top of the fixing rod is provided with a groove, and the inner wall of the fixing rod is threaded with an expansion bolt;
[0006] The reinforcement mechanism includes a round tube, a round rod slidably connected to the inner wall of the round tube, a fixing plate fixedly connected to one end of the round rod and one end of the round tube, through holes being opened on the surface of the expansion bolt nut and the surface of the fixing rod, and the round rod and the round tube being fixedly installed by nuts.
[0007] In one embodiment, the reinforcement mechanism further includes two locking rods slidably connected to the inner wall of the fixed rod. A counterweight is fixedly connected to the top of each locking rod. Both the surface of the circular tube and the surface of the circular rod have circular holes that match the locking rods. The locking rods, circular holes, and counterweights help to further limit the movement of the circular rod and circular tube, preventing horizontal movement during reinforcement and thus enhancing the stability of the circular tube, circular rod, and fixed plate when reinforcing the expansion bolts.
[0008] In one embodiment, three rubber rings are embedded in the lower surface of the counterweight, and three slots are formed on the upper inner wall of the fixing rod, the slots communicating with the groove. This arrangement facilitates the engagement of the rubber rings with the slots, enhancing the stability of the counterweight and fixing rod installation.
[0009] In one embodiment, a limiting rod is fixedly connected to one side of each of the two fixing plates, and a limiting groove matching the limiting rod is formed on the upper surface of the fixing rod. This facilitates limiting the initial installation position of the round tube and the round rod, allowing for better alignment of the round hole on the round rod with the round hole on the round tube, and also facilitates better installation of the clamping rod with the round hole.
[0010] In one embodiment, a rubber pad is fixedly connected to the inner bottom wall of the groove, and the top of the rubber pad has multiple annularly distributed strip grooves. This helps to increase the resistance to the rotation of the nut after the expansion bolt is tightened.
[0011] In one embodiment, rubber sleeves are fixedly connected to the surfaces of both the circular tube and the circular rod. The surfaces of the rubber sleeves have multiple evenly distributed annular grooves. This increases the friction between the surface of the circular tube and the inner wall of the through hole, and between the surface of the circular rod and the inner wall of the cylinder, thereby increasing the resistance to lateral movement of the circular tube and circular rod after installation.
[0012] In one embodiment, one end surface of the round rod is threaded, and the nut is fixedly connected to the round rod by the thread. This facilitates the final locking and positioning of the nut and the round rod.
[0013] In one embodiment, both the surface of the rubber ring and the inner wall of the groove are curved into an arc shape. This facilitates better compression of the rubber ring during installation.
[0014] Beneficial effects
[0015] 1. In the above-mentioned reinforcement mechanism, the round tube passes through the through hole of the fixing rod and the through hole of the expansion bolt nut, connecting the round rod and the round tube. Simultaneously, the nut is tightened onto the round rod, which helps to form a whole with the round rod and the round tube. Under the action of the two fixing plates, the horizontal movement of the round rod and the round tube is limited. The interaction between the round rod, the round tube, and the fixing plates prevents the expansion bolt from rotating horizontally or moving longitudinally during the fixing process, thus ensuring the stability of the expansion bolt when fixing the bracket. At the same time, the clamping rod, the round hole, and the counterweight further limit the movement of the round rod and the round tube after installation, preventing horizontal movement during reinforcement. This strengthens the stability of the round tube, the round rod, and the fixing plates when reinforcing the expansion bolt, ensuring the fixing effect of the expansion bolt and preventing displacement during use after bracket installation. This enhances the stability of the bracket when supporting and fixing the radar antenna.
[0016] 2. Under the action of the rubber ring and the slot, it is beneficial for the counterweight block and the fixing rod to form a snap-fit between the rubber ring and the slot, which enhances the stability of the installation of the counterweight block and the fixing rod, thereby enhancing the stability of the reinforcement mechanism when reinforcing the expansion bolts.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] The following is combined Figures 1-5 This invention describes a radar antenna support positioning mechanism to prevent offset.
[0027] In one embodiment, a radar antenna bracket positioning mechanism for preventing offset includes: four fixing rods 100 respectively fixedly connected to the four corners of the bottom end of the bracket, the top of the fixing rod 100 is provided with a groove 110, and the inner wall of the fixing rod 100 is threaded with an expansion bolt 200.
[0028] The reinforcement mechanism 300 includes a round tube 310, a round rod 320 slidably connected to the inner wall of the round tube 310, a fixing plate 330 fixedly connected to one end of the round rod 320 and one end of the round tube 310, and through holes 340 are opened on the surface of the nut of the expansion bolt 200 and the surface of the fixing rod 100. The round rod 320 and the round tube 310 are fixedly installed by a nut 350.
[0029] In this embodiment, the four fixing rods 100 are arranged in a rectangular shape, and the bottom end of the fixing rods 100 is flush with the bottom end of the radar antenna bracket.
[0030] One of the fixing plates 330 that is installed with the round tube 310 has a mounting hole that matches the round rod 320. When the round rod 320 is inserted into the round tube 310 and the other fixing plate 330 is pressed against the other end of the round tube 310, the other end of the round rod 320 will pass through the other fixing plate 330. At this time, the nut 350 is tightened with the round rod 320, and the nut 350 is pressed against one of the fixing plates 330, thereby installing and fixing the round rod 320 and the round tube 310 to form a whole.
[0031] When the device is installed, after the expansion bolt 200 is tightened into place using the installation tool, the through hole 340 of the expansion bolt 200 nut is aligned with the through hole 340 of the fixing rod 100. Therefore, the round tube 310 can pass horizontally through the through hole 340 of the fixing rod 100 and the through hole 340 of the expansion bolt 200 nut.
[0032] The round tube 310 is passed through the through hole 340 by a horizontal line, and the round rod 320 is installed with the round tube 310. After the round tube 310 and the round rod 320 are further fixed with the nut 350, the opposite sides of the two fixing plates 330 are pressed against the surface of the fixing rod 100.
[0033] It should be noted that a gasket is provided between one side of the nut 350 and the side of one of the fixing plates 330 away from the round tube 310. The gasket is a rubber component. After the nut 350 is tightened, the gasket abuts against the side of one of the fixing plates 330 away from the round tube 310.
[0034] The installation of the bracket with expansion bolts 200 is a well-known technology, therefore, the specific installation of expansion bolts 200 will not be described in detail.
[0035] like Figure 2 and Figure 3 As shown, the reinforcement mechanism 300 also includes two locking rods 360 that are slidably connected to the inner wall of the fixed rod 100. A counterweight 370 is fixedly connected to the top of the locking rod 360. The surface of the round tube 310 and the surface of the round rod 320 are both provided with round holes 380 that match the locking rods 360.
[0036] In this embodiment, the inner wall of the fixing rod 100 is provided with an installation groove that matches the locking rod 360, and the installation groove is connected to the through hole 340 opened in the fixing rod 100. Therefore, when the locking rod 360 is inserted into the installation groove, the locking rod 360 will penetrate the through hole 340. The number of round holes 380 opened on the surface of the round tube 310 and the number of round holes 380 opened on the surface of the round rod 320 are both two.
[0037] The counterweight 370 is a solid cast iron component, and the diameter of the upper surface of the counterweight 370 matches the diameter of the fixing rod 100, and the diameter of the lower surface of the counterweight 370 matches the diameter of the groove 110. When the counterweight 370 is installed with the fixing rod 100, the lower surface of the counterweight 370 will enter the groove 110 and fit against the inner wall of the groove 110.
[0038] like Figure 3 and Figure 4As shown, three rubber rings 371 are embedded in the lower end of the surface of the counterweight 370, and three slots 120 are formed on the upper end of the inner wall of the fixing rod 100. The slots 120 are connected to the groove 110. The surface of the rubber rings 371 and the inner wall of the slots 120 are both curved into an arc shape.
[0039] In this embodiment, the lower end of the surface of the counterweight 370 has three annular grooves. Three rubber rings 371 are respectively embedded in the corresponding annular grooves. When the counterweight 370 is installed with the fixing rod 100, the rubber rings 371 are squeezed and contracted into the annular grooves. When the rubber rings 371 are flush with the slots 120, the rubber rings 371 will reset and enter the slots 120 due to their own elastic deformation. During the installation process, when the lower rubber ring 371 enters the upper slot 120, the force continues to push the counterweight 370 downward. At this time, the arc of the slot 120 will squeeze the corresponding rubber ring 371 to contract. After the counterweight 370 and the fixing rod 100 are installed, the three rubber rings 371 correspond one-to-one with the three slots 120 and are engaged with the corresponding slots 120.
[0040] like Figure 4 and Figure 5 As shown, a limiting rod 331 is fixedly connected to one side of each of the two fixing plates 330, and a limiting groove matching the limiting rod 331 is provided on the upper surface of the fixing rod 100.
[0041] In this embodiment, when the round tube 310 is installed with the through hole 340 of the fixing rod 100, the limiting rod 331 on the side of the corresponding fixing plate 330 enters the corresponding limiting groove. After installation, when the round rod 320 is installed with the round tube 310, the limiting rod 331 on the side of the other fixing plate 330 enters the corresponding limiting groove. At this time, the round hole 380 on the surface of the round tube 310 and the round hole 380 on the surface of the round rod 320 are on the same axis and perpendicular to the horizontal plane.
[0042] When the opposite sides of the two fixing plates 330 are pressed against the surface of the fixing rod 100, the two round holes 380 on the round tube 310 are aligned with the two round holes 380 on the round rod 320, and the center of the aligned round holes 380 coincides with the center of the corresponding mounting groove of the clamp rod 360.
[0043] like Figure 4 As shown, a rubber pad 130 is fixedly connected to the inner bottom wall of the groove 110, and the top of the rubber pad 130 has multiple strip grooves distributed in a ring.
[0044] In this embodiment, when the expansion bolt 200 is tightened in place, the bottom end of the expansion bolt 200 abuts against the top end of the rubber pad 130, thereby increasing the friction of the nut after the expansion bolt 200 is fixed.
[0045] like Figure 5 As shown, rubber sleeves 390 are fixedly connected to the surface of the round tube 310 and the surface of the round rod 320. The surface of the rubber sleeves 390 has multiple evenly distributed annular grooves.
[0046] In this embodiment, after the round tube 310 and the through hole 340 are installed, the surface of the rubber sleeve 390 installed on the surface of the round tube 310 is tightly fitted and abutted against the inner wall of the through hole 340. After the round rod 320 and the round tube 310 are installed, the surface of the rubber sleeve 390 installed on the surface of the round rod 320 is tightly fitted and abutted against the inner wall of the round tube 310.
[0047] like Figure 5 As shown, one end of the round rod 320 is threaded, and the nut 350 is fixedly connected to the round rod 320 by the thread. The final connection and locking are completed by rotating the nut 350 using the thread.
[0048] Working principle: When using this device to position the radar antenna bracket, the bracket is placed in the designated position and fixed using the expansion bolts 200 at the four corners of the bracket's bottom. During the fixing process, the operator first tightens one of the expansion bolts 200. After tightening the expansion bolt 200, the round tube 310 in the corresponding reinforcement mechanism 300 is horizontally inserted through the through hole 340 of the fixing rod 100 and the through hole 340 of the expansion bolt 200 nut. After insertion, the corresponding round rod 320 is inserted into the round tube 310, and the nut 350 is tightened to the round rod 320. At this point, the installation of the round rod 320 and the round tube 310 is completed, and the two fixing plates 330 are aligned. The opposite side abuts against the surface of the fixing rod 100, and during the installation process, the limiting rods 331 on the two fixing plates 330 enter the corresponding limiting grooves. After this operation is completed, the counterweight 370 is installed with the fixing rod 100. During installation, the two locking rods 360 will respectively penetrate longitudinally through the round hole 380 that coincides with the round rod 320 and the round tube 310, and at the same time press the counterweight 370 down into the groove 110 so that the rubber ring 371 is engaged with the locking groove 120. When the counterweight 370 can no longer move down, the reinforcement operation of the reinforcement mechanism 300 on the expansion bolt 200 is completed. The installation and reinforcement operation of multiple expansion bolts 200 can be completed in the same way.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
