Description

Technical Field

[0001] This utility model relates to the field of environmental testing technology, and in particular to an auxiliary device for radar electromagnetic environment testing. Background Technology

[0002] Electromagnetic environment testing equipment is typically used to evaluate the performance and reliability of radar systems under different electromagnetic environmental conditions, and is an important step before radar site selection. Therefore, the electromagnetic environment around the radar site is usually tested.

[0003] In the prior art, for example, Chinese Patent No. CN222338468U discloses a radar electromagnetic environment testing auxiliary device, belonging to the field of electromagnetic environment testing technology. A radar electromagnetic environment testing auxiliary device includes a fixed base with rotatably mounted legs and an antenna. It also includes a telescopic cylinder fixedly mounted on the fixed base, wherein a telescopic rod is slidably mounted inside the telescopic cylinder, a mounting base is fixedly mounted on the top of the telescopic rod, a connecting seat is rotatably mounted on the mounting base, and the antenna is detachably mounted on the connecting seat. The telescopic cylinder is provided with a limiting component to restrict the sliding of the telescopic rod. This invention, by having the telescopic rod slidably mounted inside the telescopic cylinder, facilitates adjustment of the antenna height, and by rotatably mounting the connecting seat on the mounting base, allows for rotational testing with the antenna, thus improving the testing range.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: although it can be slidably set inside the telescopic cylinder by the telescopic rod, making it easy to adjust the height of the antenna, and the connecting seat can be rotated and set on the mounting base, allowing for testing with the antenna in motion, which helps to improve the testing range, the device lacks a protective structure for the antenna during transportation. The antenna may be deformed or damaged due to collisions. When the antenna is disassembled and placed separately, a separate protective structure is required, which is quite troublesome, resulting in low ease of use of the device. Utility Model Content

[0005] The purpose of this invention is to solve the problem that while existing devices can be easily adjusted by sliding the telescopic rod inside the telescopic cylinder, and the connecting seat can be rotated on the mounting base to allow for testing with the antenna, thus improving the testing range, they lack antenna protection structures during transportation. This means the antenna may be deformed or damaged due to collisions, and separate protection structures are required when disassembling and storing the antenna separately, which is cumbersome and results in low ease of use.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a radar electromagnetic environment testing auxiliary device, comprising: a storage box, the top of which is movably connected to a protective cover via a hinge; the interior of the storage box is provided with an extension mechanism, a tilt angle adjustment mechanism, and a horizontal azimuth adjustment mechanism; the extension mechanism includes two round rods and a U-shaped plate; both round rods are fixedly connected to the storage box; a U-shaped strip is rotatably connected to the outer surface of the round rods; round rods are fixedly connected to opposite sides of the two arms of the U-shaped strip; an H-shaped strip is rotatably connected to the outer surface of the round rods; connecting rods are rotatably connected to opposite sides of the H-shaped strip; a slider is fixedly connected to one end of each connecting rod; two guide rods are symmetrically fixedly connected to opposite sides of the two arms of the U-shaped plate; both sliders are slidably connected to the guide rods; the bottom of the tilt angle adjustment mechanism is fixedly installed on the top of the extension mechanism; the bottom of the horizontal azimuth adjustment mechanism is fixedly installed on the top of the tilt angle adjustment mechanism; and the horizontal azimuth adjustment mechanism includes an antenna.

[0007] Preferably, a limiting hole is provided on the side of the U-shaped strip near the round rod, two insertion holes are symmetrically provided on one side of the storage box, and storage strips are fixedly connected to opposite sides of the inner wall of the storage box, with insertion rods engaged inside the storage strips.

[0008] Preferably, a screw is slidably connected to the side of the U-shaped strip away from the round rod, and a limit hole is provided on the side of the H-shaped strip close to the round rod.

[0009] Preferably, the tilt angle adjustment mechanism includes two fixed blocks, both of which are fixedly connected to a U-shaped plate. A square groove is provided on the top of the U-shaped plate, and a rotating rod is rotatably connected to the opposite side of the inner wall of the square groove. A worm wheel is fixedly connected to the outer surface of the rotating rod, and a worm is rotatably connected to the opposite side of the two fixed blocks. The worm meshes with the worm wheel, and a knob is fixedly connected to one end of the worm.

[0010] Preferably, the horizontal orientation adjustment mechanism further includes a hollow plate, which is fixedly connected to a rotating rod. A sliding plate is slidably connected inside the hollow plate, and a disc is fixedly connected to the top of the sliding plate. A movable rod is rotatably connected to the top of the disc, and the movable rod is fixedly connected to the antenna.

[0011] Preferably, a connecting strip is fixedly connected to the outer surface of the movable rod, and a screw rod is threadedly connected to the top of the connecting strip. The top of the disc has multiple circular holes arranged in a circumferential array, and one end of the screw rod is movably connected to the inside of the circular holes.

[0012] Preferably, a screw three is threadedly connected to one side of the hollow plate, and one end of the screw three extends into the interior of the hollow plate.

[0013] Preferably, the storage box and the protective cover are connected by snap-fit, an elastic sponge pad is fixedly connected to the top of the inner wall of the protective cover, a handle is fixedly connected to the top of the protective cover, and two handles are symmetrically fixedly connected to the top of the U-shaped plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model, through the cooperation of the extension mechanism, the tilt angle adjustment mechanism and the horizontal azimuth adjustment mechanism, can move the antenna out of the storage box and arrange it to test the electromagnetic environment of the nearby radar. Similarly, the antenna can be stored inside the storage box and protected by the elastic sponge pad. This can prevent the antenna from being damaged by collision, thereby improving the protection effect of the antenna.

[0016] 2. In this utility model, by setting up an extension mechanism, when the U-shaped strip and the H-shaped strip are in a vertical state, the screw is turned by hand to insert it into the limiting hole, so that the U-shaped strip and the H-shaped strip are in a relatively fixed state. Then, the insertion rod is inserted into the insertion hole and the limiting hole, so that the U-shaped strip and the storage box are in a relatively fixed state. This allows the antenna to be moved out of the storage box and moved to a suitable height, which facilitates subsequent testing of the electromagnetic environment of the nearby radar.

[0017] 3. In this utility model, by setting up a tilt angle adjustment mechanism, when the screw is turned by hand, it drives the worm gear to rotate, which in turn drives the rotating rod to rotate, and simultaneously drives the horizontal azimuth adjustment mechanism to rotate, so that the antenna is tilted at an appropriate angle. Under the interaction of the worm gear and the worm wheel, self-locking is achieved, thus making it easy to keep the antenna at a certain tilt angle.

[0018] 4. In this utility model, by setting up a horizontal orientation adjustment mechanism, when the screw two is rotated by hand to move it out of the inside of one of the round holes, the antenna is released from its position. At this time, the antenna can be adjusted horizontally with the help of the movable rod. Then, by rotating the screw two in the opposite direction by hand to insert it into the inside of the other round hole, the antenna is restricted, thus facilitating the adjustment of the antenna's orientation.

Detailed Implementation

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Examples, such as Figures 1-5As shown, this utility model provides a radar electromagnetic environment testing auxiliary device, including: a storage box 1, the top of which is movably connected to a protective cover 101 via a hinge; the interior of the storage box 1 is provided with an extension mechanism, a tilt angle adjustment mechanism, and a horizontal orientation adjustment mechanism; the extension mechanism includes two round rods 2 and a U-shaped plate 203; both round rods 2 are fixedly connected to the storage box 1; a U-shaped strip 201 is rotatably connected to the outer surface of the round rods 2; round rods 211 are fixedly connected to opposite sides of the two arms of the U-shaped strip 201; and round rods 211 are... The outer surface of 11 is rotatably connected to an H-shaped strip 210. Each opposite side of the H-shaped strip 210 is rotatably connected to a connecting rod 209. One end of the connecting rod 209 is fixedly connected to a slider 208. Two guide rods 207 are symmetrically fixedly connected to opposite sides of the two arms of the U-shaped plate 203. Both sliders 208 are slidably connected to the guide rods 207. The bottom of the tilt angle adjustment mechanism is fixedly installed on the top of the extension mechanism. The bottom of the horizontal azimuth adjustment mechanism is fixedly installed on the top of the tilt angle adjustment mechanism. The horizontal azimuth adjustment mechanism includes an antenna 3.

[0029] Furthermore, such as Figures 1-5 As shown, a limiting hole 202 is provided on the side of the U-shaped strip 201 near the round rod 2. Two insertion holes 102 are symmetrically provided on one side of the storage box 1. Storage strips 104 are fixedly connected to opposite sides of the inner wall of the storage box 1. Insert rods 105 are engaged inside the storage strips 104. The storage strips 104 facilitate the placement of the insert rods 105. By passing the insert rods 105 through the insertion holes 102 and the limiting hole 202, the U-shaped strip 201 and the storage box 1 can be kept in a relatively fixed state. At this time, the U-shaped strip 201 is in a vertical state.

[0030] Furthermore, such as Figures 1-5 As shown, a screw 205 is slidably connected to the side of the U-shaped strip 201 away from the round rod 2. A limiting hole 212 is provided on the side of the H-shaped strip 210 near the round rod 211. By rotating the screw 205 by hand, it can be inserted into the limiting hole 212, so that the H-shaped strip 210 and the U-shaped strip 201 can be kept in a relatively fixed state.

[0031] Furthermore, such as Figures 1-5As shown, the tilt angle adjustment mechanism includes two fixed blocks 402, both of which are fixedly connected to a U-shaped plate 203. A square groove 204 is provided on the top of the U-shaped plate 203. A rotating rod 4 is rotatably connected to the opposite side of the inner wall of the square groove 204. A worm gear 401 is fixedly connected to the outer surface of the rotating rod 4. A worm 403 is rotatably connected to the opposite side of the two fixed blocks 402. The worm 403 is meshed with the worm gear 401. A knob 404 is fixedly connected to one end of the worm 403. By manually rotating the screw 304, the worm 403 is driven to rotate. Then, under the action of the meshing of the worm 403 and the worm gear 401, the worm gear 401 can drive the rotating rod 4 to rotate, which simultaneously drives the horizontal azimuth adjustment mechanism to rotate, so that the antenna 3 tilts at an appropriate angle.

[0032] Furthermore, such as Figures 1-5 As shown, the horizontal azimuth adjustment mechanism also includes a hollow plate 305, which is fixedly connected to the rotating rod 4. A sliding plate 307 is slidably connected inside the hollow plate 305. A disc 301 is fixedly connected to the top of the sliding plate 307. A movable rod is rotatably connected to the top of the disc 301. The movable rod is fixedly connected to the antenna 3. With the above arrangement, the sliding plate 307 can slide upward along the inside of the hollow plate 305 to adjust the distance between the antenna 3 and the U-shaped plate 203, which facilitates the subsequent tilting of the antenna 3. With the cooperation of the movable rod, the horizontal azimuth of the antenna 3 can be adjusted.

[0033] Furthermore, such as Figures 1-5 As shown, a connecting strip 303 is fixedly connected to the outer surface of the movable rod, and a screw 304 is threadedly connected to the top of the connecting strip 303. The top of the disc 301 has multiple circular holes 302 arranged in a circumferential array. One end of the screw 304 is movably connected to the inside of the circular hole 302. By rotating the screw 304 by hand, it can be inserted into the circular hole 302, which can limit the connecting strip 303, thereby keeping the antenna 3 in a relatively fixed state.

[0034] Furthermore, such as Figures 1-5 As shown, a screw 306 is threadedly connected to one side of the hollow plate 305. One end of the screw 306 extends into the interior of the hollow plate 305. The screw 306 facilitates the locking of the slide plate 307.

[0035] Furthermore, such as Figures 1-5 As shown, the storage box 1 and the protective cover 101 are connected by a snap-fit. An elastic sponge pad 103 is fixedly connected to the top of the inner wall of the protective cover 101. A handle 1 is fixedly connected to the top of the protective cover 101. Two handles 2 are symmetrically fixedly connected to the top of the U-shaped plate 203. The elastic sponge pad 103 is designed to protect the antenna 3. The handle 1 makes it easy to carry the device. The handles 2 make it easy to pull the U-shaped plate 203 upward.

[0036] Working principle: In use, bring the device to the location where radar electromagnetic environment testing is required by taking handle one, place the device on the ground, open the protective cover 101, and then grasp handle two and pull the U-shaped plate 203 upwards. This causes the guide rod 207, slider 208, and connecting rod 209 to move upwards, applying an upward force to the guide rod 207. This causes the two ends of the guide rod 207 to rotate at appropriate angles around the connecting rod 209 and the round rod 211, respectively, increasing the angle between the H-shaped strip 210 and the U-shaped strip 201. An upward force is applied to the U-shaped strip 201 by the round rod 211, causing the U-shaped strip 201 to rotate upward around the round rod 211 by an appropriate angle. Simultaneously, the slider 208 slides a suitable distance to one side along the outer surface of the guide rod 207 until the U-shaped strip 201 and the H-shaped strip 210 are kept vertical. At this point, the screw 205 is manually rotated to insert it into the limiting hole 212, keeping the U-shaped strip 201 and the H-shaped strip 210 in a relatively fixed state. Then, the insertion rod 105 is removed from the storage strip 104 and inserted into the insertion hole 102 and the limiting hole 202. In the process, keep the U-shaped strip 201 and the storage box 1 relatively fixed, and position the antenna 3 at a suitable height. Then, pull the disc 301 upward by hand, causing the sliding plate 307 to slide upward a suitable distance along the inside of the hollow plate 305. Next, rotate the screw 306 by hand to move it inward into the hollow plate 305, thus securing the sliding plate 307 and increasing the distance between the antenna 3 and the U-shaped plate 203. Finally, rotate the screw 304 by hand to move it out from inside one of the round holes 302, releasing the restriction on the antenna 3. At this point, it can be... The antenna 3 is adjusted horizontally with the help of the movable rod. Then, by manually rotating the screw 304 in the opposite direction, it is inserted into the other round hole 302 to limit the antenna 3. Then, by manually rotating the screw 304, the worm gear 403 is rotated. Then, under the action of the meshing of the worm gear 403 and the worm wheel 401, the worm wheel 401 can drive the rotating rod 4 to rotate, which simultaneously drives the horizontal azimuth adjustment mechanism to rotate, so that the antenna 3 is tilted at an appropriate angle. This allows the device to test the electromagnetic environment of the nearby radar with the help of the antenna 3.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
