Description

Technical Field

[0001] The utility model belongs to the technical field of antenna testing, and in particular relates to a device for supporting a horn antenna during the horn antenna testing process. Background Art

[0002] Horn antennas are widely used, high-performance microwave antennas. They feature a simple structure, wide bandwidth, high gain, high power handling, and ease of adjustment and use. They play a vital role in radar, satellite communications, and radio communications. Horn antenna operating parameters, including frequency, gain, beamwidth, standing wave ratio (SWR), phase congruence, and amplitude congruence, directly determine antenna performance. Therefore, these parameters are often determined through testing during the antenna design and production process to ensure performance meets specifications.

[0003] For horn antennas, the general testing method is to place the horn antenna in a microwave darkroom environment and install it on a specific test fixture for testing. For example, CN201320613030.0 discloses a test horn antenna bracket, which has a base, left and right sides, and first and second brackets located at the top of the left and right sides, respectively. It can support the horn antenna at a height of 1m from the ground. The bracket cannot change the support height or angle; CN202123220392.7 discloses a test bracket for laboratory horn antennas, which includes a base, a support rod, a fixing mechanism, and a rotating mechanism. The bracket position can be adjusted by the universal wheels provided on the base, and the height can be adjusted by the length of the base legs. The rotating mechanism can change the orientation of the horn antenna to adapt to different laboratory spaces, but the test bracket cannot change the support angle.

[0004] It can be seen that there are some supporting devices in the prior art that can fix the horn antenna at a specific height or within an adjustable height range during testing, but these supporting devices cannot change the supporting angle, making it difficult to achieve a good match with horn antennas of various models and sizes.

DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is described below with reference to the accompanying drawings and embodiments.

[0025] <Example>

[0026] Figure 1 It is a structural schematic diagram of the support device for testing a horn antenna according to an embodiment of the utility model when supporting a horn antenna to be tested.

[0027] like Figure 1 As shown, a support device for testing a horn antenna (hereinafter referred to as the support device) 100 can be installed on a conventional horn antenna testing platform 200 and is used to support the horn antenna 300 under test during testing. The support device 100 includes a connection end support mechanism 10 and a main body support mechanism 20. The connection end support mechanism 10 corresponds to the connection end (the narrow end in the figure) of the horn antenna 300 under test and is used to support this end. The main body support mechanism 20 corresponds to the main body (i.e., the horn mouth) of the horn antenna 300 under test and is used to support the main body and bear the majority of the weight of the horn antenna 300 under test. For ease of explanation, the direction from the center of the connection end to the center of the horn mouth of the horn antenna 300 under test is referred to as the front-to-back direction, with the horn mouth side being the front and the connection end side being the rear.

[0028] The connection end support mechanism 10 includes a support platform base 11 and a lifting support platform 12 installed on the support platform base 11 .

[0029] Figure 2 It is a structural schematic diagram of the support platform base of an embodiment of the present utility model.

[0030] like Figure 1-2As shown, the support platform base 11 includes a support platform bottom plate 111 , two support platform side plates 112 , a plurality of reinforcing ribs 113 and a plurality of scales 114 .

[0031] The support platform bottom plate 111 is in the shape of a flat plate and is provided with connection holes that match the horn antenna test platform 200 . When in use, it is installed on the test platform through the connection holes, thereby supporting the entire connection end support mechanism 10 .

[0032] The two support platform side panels 112 are respectively provided at the two ends of the support platform bottom panel 111, and extend vertically upward from the ends of the support platform bottom panel 111. Each support platform side panel 112 is also provided with at least two vertically extending elongated holes, which serve as base connection holes 1121 for mounting the lifting support platform 12.

[0033] The reinforcing ribs 113 are arranged on the outside of the support platform side plate 112, with their bottom ends fixedly connected to the support platform bottom plate 111, and their sides fixedly connected to the outer side surfaces of the support platform side plates 112, thereby supporting and increasing the strength of the support platform side plates 112.

[0034] Figure 3 It is a structural schematic diagram of the lifting support platform of an embodiment of the utility model.

[0035] like Figure 1 、 3 As shown, the lifting support platform 12 includes a lifting support plate 121 and a supporting assembly 122 .

[0036] There are two lifting support plates 121 , and each lifting support plate 121 is composed of a side plate portion 1211 and a flat plate portion 1212 .

[0037] The side panels 1211 extend generally in the vertical direction and are provided with a plurality of side panel connection holes 1213 extending therethrough. These side panel connection holes 1213 are used to connect to the base connection holes 1121 via fasteners such as bolts, thereby mounting the lift support platform 12 on the support platform base 11. Because the base connection holes 1121 are elongated, the height of the lift support platform 12 on the support platform side panels 111 can be adjusted.

[0038] The flat plate portion 1212 is arranged at the top end of the side plate portion 1211 and extends roughly in the horizontal direction. The flat plate portion 1212 is provided with a long waist hole with a length direction in the front-to-back direction. The long waist hole serves as a support mounting hole 1214 for mounting the support assembly 122.

[0039] The scales 114 are respectively provided on the two support platform side plates 112 for marking the height of the lifting support platform 12 (ie, the height of the flat plate portion 1212 in the lifting support plate 121 relative to the bottom end of the support platform 112 side plate).

[0040] The supporting assembly 122 is mounted on the support base 122. In this embodiment, there are two groups of supporting assemblies 122, and each group of supporting assemblies 122 includes a supporting plate 1221, a pressing plate 1222 and a fixing member 1223.

[0041] The support plate 1221 is used to support the connection end of the horn antenna 300 under test. It is in the shape of an elongated plate, with its length generally perpendicular to the front-to-back direction. Support connection holes 1224 are provided at both ends of the support plate 1221. By connecting these holes to the support mounting holes 1214 using fasteners such as bolts, the support assembly 122 is securely mounted on the lifting support plate 121.

[0042] In addition, multiple pairs of support plate positioning holes 1225 are provided on the support plate 1221. The two support plate positioning holes 1225 of each pair are symmetrically distributed on the two ends of the support plate 1221, and the distances between different pairs of support hole positioning plates 1225 and the center of the length direction of the support plate 1221 are different.

[0043] The pressure plate 1222 is located above the support plate 1221 and is shaped like a long strip, with its length generally perpendicular to the front-to-back direction. The pressure plate 1222 is provided with multiple pairs of pressure plate positioning holes 1226 . The distribution pattern of these pressure plate positioning holes 1226 is the same as the distribution pattern of the support plate positioning holes 1225 on the support plate 1221, and each pressure plate positioning hole 1226 corresponds one-to-one with each support plate positioning hole 1225.

[0044] In each supporting assembly 122, there are two fixing members 1223 for connecting the supporting plate positioning hole 1225 and the pressing plate positioning hole 1226. In this embodiment, the fixing members 1223 are disc bolts (including nuts, which are not shown in the figure).

[0045] When the horn antenna 300 to be tested is installed, its connection end is clamped between the two sets of supporting components 122 . Specifically, during installation, by adjusting the positions of the support plates 1221 of the two groups of support assemblies 122 installed in the support mounting holes 1214, the spacing between the support plates 1221 of the two groups of support assemblies 122 is adjusted to match the length of the connecting end of the horn antenna 300 to be tested; at the same time, a pair of support plate positioning holes 1225 with appropriate spacing are selected (the spacing between the pair of support plate positioning holes 1225 is approximately the same as the width of the connecting end of the horn antenna 300 to be tested, or the spacing is slightly larger than the width of the connecting end), the connecting end of the horn antenna 300 to be tested is placed on the two support plates 1221, and the selected support plate positioning holes 1225 are connected to the corresponding pressure plate positioning holes 1226 with the fixing members 1223, so that the pressure plates 1222 of the two groups of support assemblies 122 simultaneously press the connecting end of the horn antenna 300 to be tested on the support plate 121, thereby completing the fixation of the connecting end.

[0046] Figure 4 This is a schematic structural diagram of the support mechanism of an embodiment of the utility model. Figure 5 It is a side structural schematic diagram of the support mechanism of an embodiment of the utility model.

[0047] like Figure 1 、 4 As shown in FIG. 5 , the main body support mechanism 20 includes a bracket 21 , a support plate 22 , a support plate 23 and an adjustment assembly 24 .

[0048] The bracket 21 is placed on the test platform, and the support plate 22 is fixedly mounted on the top of the bracket 21 and extends generally horizontally. In this embodiment, the support plate 22 is provided with two circular holes 221 and two elongated holes 222, which serve as adjustment mounting holes. The two circular holes 221 are located relatively forward, one on each side of the support plate 22; the two elongated holes 222 are located relatively rearward, one on each side of the support plate 22, and the longitudinal direction of the elongated holes 222 is the front-to-back direction. Furthermore, the center of each circular hole 221 is located on the extension of the longitudinal midline of the elongated holes 222 on the same side.

[0049] The support plate 23 is located above the support plate 22 and is used to support the main body of the horn antenna 300 to be tested. A rubber pad is laid on the upper surface of the support plate 23 to increase friction and protect the outer surface of the main body of the horn antenna 300 to be tested.

[0050] The adjustment assembly 24 is used to connect the support plate 22 and the supporting plate 23 and simultaneously realize height and angle adjustment of the supporting plate 23 .

[0051] In this embodiment, there are four groups of adjustment assemblies 24, each group of adjustment assemblies 24 corresponding to the circular hole 221 or the long waist hole 222, and each adjustment assembly 24 includes a lead screw 241 and a flange nut 242. During assembly, the flange nut 242 is set on the support plate 22 at the circular hole 221 or the long waist hole 222. The top of the lead screw 241 is hinged to the lower surface of the support plate 23, and the lower end is screwed with the flange nut 242 and then passes through the circular hole 221 or the long waist hole 222. By rotating the flange nut 242, the length of the lead screw 241 passing through the circular hole 221 or the long waist hole 222 can be adjusted, thereby changing the exposed height of the lead screw 241 (i.e., the height exposed above the support plate 22), thereby adjusting the angle and overall height of the support plate 23.

[0052] Figure 6 This is a schematic diagram of the structure of the support device for testing a horn antenna according to an embodiment of the utility model when testing a horn antenna of a certain model and specification. Figure 7It is a structural schematic diagram of the support device for testing a horn antenna according to an embodiment of the utility model when testing a horn antenna of another model and specification.

[0053] Figure 6-7 In the figure, horn antennas 300 and 500 to be tested are both test objects, and horn antennas 400 and 600 are corresponding standard horn antennas, which are used to transmit test signals to horn antennas 300 and 500 to be tested during the test. Horn antennas 400 and 600 are fixedly mounted using other conventional mounting structures (not shown in the figure), and their positions do not change during the test. However, horn antennas 300 and 500 to be tested must be aligned with horn antennas 400 and 600, respectively, during the test to receive the test signals.

[0054] like Figure 6-7 As shown, when it is necessary to test the horn antenna 300 to be tested or the horn antenna 500 to be tested with different specifications and sizes (such as different horn opening angles, different overall lengths and heights of the horn antenna, etc.), the exposed height of each screw 241 in the adjustment assembly 24 can be adjusted by the flange nut 242, and the angle and overall height of the support plate 23 can be adjusted to adapt to the lower surface of the main part of the horn antenna 300 to be tested or the horn antenna 500 to be tested, so that the support plate 23 can support the main part. In addition, the height of the lifting support platform 12 can also be adjusted so that the overall height of the supporting assembly 122 can match the height position of the connection end of the horn antenna to be tested 300 or the horn antenna to be tested 500. At the same time, the spacing between the supporting plates 1221 of the two groups of supporting assemblies 122 can also be adjusted to match the length of the connection end of the horn antenna to be tested 300 or the horn antenna to be tested 500, and by selecting a suitable pair of supporting plate positioning holes 1225 and corresponding pressure plate positioning holes 1226, the spacing between the fixing parts 1223 can be adjusted to match the width of the connection end of the horn antenna to be tested 300 or the horn antenna to be tested 500.

[0055] According to the support device 100 for testing the horn antenna provided in this embodiment, since the connection end support structure 10 can support the connection end of the horn antenna, the main body support mechanism 20 can support the main body of the horn antenna, and the main body support mechanism 20 has a support plate 23 and multiple groups of adjustment components 24 that can adjust the height and angle of the support plate, the horn antenna support device 100 can support the main body and the connection end of the horn antenna respectively, and can change the support angle and height of the main body during this support process, so that it can form a good match with horn antennas of different specifications and sizes, and realize the support of different horn antennas.

[0056] In the embodiment, since the adjustment assembly includes a flange nut 242 and a lead screw 241, and the upper end of the lead screw 241 is hinged to the support plate 23 and the lower end is screwed to the flange nut 242 and passes through the adjustment mounting hole provided on the support plate 22, it is only necessary to rotate the flange nut 242 to change the length of the lead screw 241 exposed above the support plate 22, so that the angle and height of the support plate 23 can be adjusted through simple operations.

[0057] The connection end support mechanism 10 of the embodiment has a support platform base 11 and a lifting support platform 12. The lifting support platform 12 has a liftable lifting support plate 121, and its overall height can be raised and lowered, so it can adapt to the height position of the connection end of horn antennas of different models and specifications.

[0058] Because the lifting support platform 12 also includes a support assembly 122, which includes a support plate 1221 and a pressure plate 1222, the pressure plate 1222 can press the connection end of the horn antenna against the support plate 1221 to provide stable support for the connection end. Furthermore, because there are two sets of support assemblies 122 and the lifting support plates 121 are provided with long waist holes that serve as support mounting holes 1214, the lengths of the horn antenna connection ends can be adjusted by adjusting the spacing between the support plates 1221 in the two sets of support assemblies 122. Furthermore, because the support plates 1221 are provided with multiple pairs of support plate positioning holes 1225 and the pressure plate 1222 are provided with multiple pairs of corresponding pressure plate positioning holes 1226, the widths of the horn antenna connection ends can be adjusted by selecting different combinations of support plate positioning holes 1225 and pressure plate positioning holes 1226.
