Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a radio interference testing device. Background Technology

[0002] In recent years, with the expanding applications of walkie-talkies, the use scenarios for walkie-talkies and monitors have also increased. However, when a walkie-talkie is placed near a monitor, the monitor may experience screen flickering, resulting in unclear display and inconvenience. Currently, there have been numerous customer complaints regarding screen flickering or even complete blackouts when using industrial monitors and industrial tablets in conjunction with walkie-talkies, affecting normal customer use. Therefore, to reduce the occurrence of blackouts and flickering screens when customers use various industrial monitors with walkie-talkies, we conduct pre-shipment testing for walkie-talkie interference to allow for optimization and improvement measures for monitors with poor walkie-talkie interference performance.

[0003] However, there are currently no relevant industry standards specifying the testing methods for walkie-talkie interference. The testing methods for walkie-talkie interference are usually conducted manually, which can easily lead to problems such as missed angles, inaccurate test distances, and even different measurement results from different testers, which can easily result in misjudgments of test results. Utility Model Content

[0015] In one embodiment, the mounting bracket has a first groove and a second groove recessed on one end face facing the movable seat, and the first groove and the second groove are intersecting.

[0016] The connecting part slides in conjunction with one of the first slide groove and the second slide groove.

[0017] In one embodiment, one of the first slide groove and the second slide groove is configured as a mating groove, and the other is configured as an idle groove. When the connecting part is movably installed in the mating groove, the size of the connecting part is larger than the size of the idle groove in the width direction of the idle groove.

The plurality of abutment portions are respectively used to abut against a plurality of side ends of the product to be tested in the second direction and / or the third direction, so as to jointly clamp the product to be tested in the second direction and / or the third direction.

[0021] In one embodiment, the second mounting portion is movably adjustable in the first direction, the second direction, and the third direction, with the first direction, the second direction, and the third direction intersecting each other.

[0022] In one embodiment, the second position adjustment structure includes:

[0023] A support rod extends along the third direction and is rotatably configured along the axis extending along the third direction;

[0024] A first adjusting rod extends along the second direction and is connected to the support rod via a first mating part. The first mating part is movablely engaged with the support rod in the third direction and with the first adjusting rod in the second direction.

[0025] The second adjusting rod extends along the first direction and is connected to the first adjusting rod through a second mating part.

At this time, the user can adjust the position of the second mounting part to adjust the position of the radio transmitter and determine the distance and angle at which the radio transmitter emits radio waves. Then, the user can control the radio transmitter to emit radio waves in the testing chamber. At this time, the testing chamber can confine the radio waves emitted by the radio transmitter to the testing chamber and shield external interference, so that the product under test is only interfered with by the radio waves emitted by the radio transmitter. During the continuous emission of radio waves by the radio transmitter, the user can manipulate the first mounting part to move the product under test, thereby adjusting the relative position between the product under test and the radio transmitter.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0044] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0046] This invention proposes a radio interference testing device. It aims to improve upon existing testing methods, which typically rely on manual simulation and are prone to problems such as missed angles, inaccurate testing distances, and inconsistent measurement results from different testers, leading to misinterpretations of test results.

[0047] Please see Figure 1-4 In one embodiment of the present invention, the radio interference testing device 100 includes a testing chamber 1, a first position adjustment structure 2, a second position adjustment structure 3, and a radio transmitter 4. The first position adjustment structure 2 has a first mounting part whose position is adjustable. The first mounting part is located in the testing chamber 1 and is used for mounting the product 5 to be tested. The second position adjustment structure 3 has a second mounting part located in the testing chamber 1 and whose position is adjustable. The second mounting part is located on one side of the first mounting part in a first direction, and the position of the second mounting part relative to the first mounting part is adjustable. The radio transmitter 4 is located in the testing chamber 1 and is mounted on the second mounting part. The radio transmitter 4 is used to transmit radio waves.

[0048] In the technical solution of this utility model, when the user needs to conduct a radio interference test on the product 5 to be tested, the product 5 to be tested is first installed on the first mounting part, and the radio transmitter 4 is installed on the second mounting part. At this time, the user can adjust the position of the second mounting part to adjust the position of the radio transmitter 4, and determine the distance and angle at which the radio transmitter 4 emits radio waves. Then, the user can control the radio transmitter 4 to emit radio waves in the test chamber 1. At this time, the test chamber 1 can confine the radio waves emitted by the radio transmitter 4 to the test chamber 1 and can shield external interference, so that the product 5 to be tested is only interfered with by the radio waves emitted by the radio transmitter 4. During the continuous emission of radio waves by the radio transmitter 4, the user can manipulate the first mounting part to move the product 5 to be tested, so as to adjust the relative position between the product 5 to be tested and the radio transmitter 4. In this way, the anti-interference ability of the product 5 to be tested against the radio waves emitted by the radio transmitter 4 in multiple directions and distances can be tested. With this setup, the radio interference testing device 100 can flexibly simulate different usage scenarios according to the different anti-interference requirements of the products under test 5 for radio waves, thereby realizing the detection of multiple interference angles and directions, reducing the risk of misjudgment due to human differences caused by purely manual testing, and ensuring the accuracy of the test results.

[0049] It should be noted that in this utility model, the product to be tested 5 is set as a display.

[0050] It is understood that in this invention, before performing radio interference testing on the product 5 to be tested, the position of the second mounting part needs to be adjusted to adjust the position and distance of the radio transmitter 4 relative to the product 5 to be tested. This invention does not limit the specific position and distance of the radio transmitter 4 relative to the product 5 to be tested. Before each radio interference test on the product 5 to be tested, the user needs to adjust the specific position and distance of the radio transmitter 4 relative to the product 5 to be tested according to the requirements of the corresponding product 5 to be tested, so as to meet the different requirements of the product 5 to be tested for radio wave interference resistance testing.

[0051] It should be noted that this utility model does not limit the specific direction of movement of the first mounting part. In one embodiment of this utility model, the first mounting part is movably adjustable in the second direction, and the second direction intersects with the first direction. In this way, the relative position and relative angle of the product under test 5 and the radio transmitter 4 in the second direction can be adjusted, so as to realize the detection of radio wave anti-interference capability at multiple angles when the product under test 5 moves in the second direction.

[0052] In another embodiment of this utility model, the first mounting part is movably adjustable in the third direction, and the first direction, the second direction and the third direction are arranged to intersect each other. In this way, the relative position and relative angle of the product under test 5 and the radio transmitter 4 in the third direction can be adjusted, thereby realizing the detection of radio wave anti-interference capability at multiple angles when the product under test 5 moves in the third direction.

[0053] In one specific embodiment of this utility model, the first mounting part is movably adjustable in the second direction or in the third direction, and the first direction, the second direction, and the third direction are arranged in pairs. With this arrangement, the user can adjust the position of the first mounting part in the second direction or in the third direction according to their own needs and the requirements for testing the anti-interference capability of the product 5 under test, thereby adjusting the position of the product 5 under test in the second direction and the third direction, thus achieving the testing of the radio wave anti-interference capability of the product 5 under test from multiple angles.

[0054] It should be further explained that in this utility model, the first direction and the second direction are arranged at an angle in the horizontal direction, and the third direction extends in the vertical direction.

[0055] Of course, this utility model does not limit the specific structural form of the first position adjustment structure 2. For example, in one embodiment of this utility model, the first position adjustment structure 2 can be set as a gantry crane, and the hook of the gantry crane forms a first mounting part. In this way, the gantry crane can drive the product to be tested 5 to move in the second direction, thereby realizing the position adjustment of the product to be tested 5 in the second direction. The hook of the gantry crane can drive the product to be tested 5 to move in the third direction, thereby realizing the position adjustment of the product to be tested 5 in the third direction.

[0056] In another embodiment of this utility model, the first position adjustment structure 2 may further include a mounting bracket 21 and a movable seat 22. The mounting bracket 21 is disposed in the testing chamber 1. The movable seat 22 is connected to the mounting bracket 21 through a connecting part 23 and is used for mounting the product 5 to be tested. The connecting part 23 is movably connected to one end of the mounting bracket 21 facing the second mounting part in the first direction. The movable seat 22 and the connecting part 23 together form the first mounting part. With this configuration, when it is necessary to adjust the position of the product 5 to be tested in the second direction, the connecting part 23 drives the movable seat 22 to move in the second direction, thereby driving the product 5 to move in the second direction, thus realizing the position adjustment of the product 5 to be tested in the second direction. When it is necessary to adjust the position of the product 5 to be tested in the third direction, the connecting part 23 drives the movable seat 22 to move in the third direction, thereby driving the product 5 to move in the third direction, thus realizing the position adjustment of the product 5 to be tested in the third direction.

[0057] In another embodiment of this utility model, the first position adjustment structure 2 can also be configured as a cylinder structure. The cylinder structure extends along a third direction and is movably disposed in the detection chamber 1 in a second direction. The cylinder rod of the cylinder structure forms a first mounting part. Thus, when it is necessary to adjust the position of the product to be tested 5 in the second direction, the cylinder structure moves along the second direction to achieve the position adjustment of the product to be tested 5 in the second direction. When it is necessary to adjust the position of the product to be tested 5 in a third direction, the cylinder rod of the cylinder structure extends or retracts along the third direction to achieve the position adjustment of the product to be tested 5 in the third direction.

[0058] Of course, in other embodiments of this utility model, the first position adjustment structure 2 can also be set to other structural forms. In actual setting, it can be selected according to the needs, and this utility model does not limit it.

[0059] Specifically, in this embodiment, the first position adjustment structure 2 includes a mounting bracket 21 and a movable seat 22.

[0060] To facilitate the smooth movement of the connecting part 23 on the mounting bracket 21, in one embodiment of this invention, the mounting bracket 21 has a first sliding groove 211 and a second sliding groove 212 recessed on one end face facing the movable seat 22. The first sliding groove 211 and the second sliding groove 212 intersect each other, and the connecting part 23 slides in cooperation with one of the first sliding groove 211 and the second sliding groove 212. It is understood that this invention does not limit the specific extension direction of the first sliding groove 211 and the second sliding groove 212. In some embodiments of this invention, the first sliding groove 211 extends along a second direction, and the second sliding groove 212 extends along a third direction. Thus, when it is necessary to adjust the position of the product 5 to be tested in the second direction, the connecting part 23 slides in cooperation with the first sliding groove 211; when it is necessary to adjust the position of the product 5 to be tested in the third direction, the connecting part 23 slides in cooperation with the second sliding groove 212.

[0061] In some other embodiments of this utility model, the first slide groove 211 extends along a third direction, and the second slide groove 212 extends along a second direction. Thus, when it is necessary to adjust the position of the product to be tested 5 in the second direction, the connecting part 23 slides with the second slide groove 212, and when it is necessary to adjust the position of the product to be tested 5 in the third direction, the connecting part 23 slides with the first slide groove 211.

[0062] In other embodiments of this utility model, the first slide groove 211 and the second slide groove 212 can also be inclined upward in the second direction and the third direction. It is only necessary to ensure that the first slide groove 211 and the second slide groove 212 are set at an angle. In this way, when the connecting part 23 slides and one of the first slide groove 211 and the second slide groove 212, the position adjustment of the product 5 to be tested can also be realized.

[0063] Specifically, in this embodiment, the first slide groove 211 extends along the second direction, and the second slide groove 212 extends along the third direction.

[0064] It should be noted that in this utility model, the first slide groove 211 and the second slide groove 212 are intersecting. In this way, when the connecting part 23 slides into one of the first slide groove 211 and the second slide groove 212, the connecting part 23 can switch from one slide groove to the other more conveniently, thereby reducing the preparation time and difficulty between two adjacent radio interference tests and improving the test efficiency.

[0065] It can be further understood that, in order to ensure the accuracy of the movement direction of the product 5 under test when it moves along the second or third direction, in one embodiment of this utility model, one of the first slide groove 211 and the second slide groove 212 is set as a mating groove, and the other is set as an idle groove. When the connecting part 23 is movably installed in the mating groove, the size of the connecting part 23 is larger than the size of the idle groove in the width direction. With this setting, for example, when the first slide groove 211 is set as the mating groove and the second slide groove 212 is set as the idle groove, the connecting part 23 slides with the first slide groove 211. At this time, the connecting part 23 slides along the extension direction of the first slide groove 211, so that the position of the product 5 under test in the second direction can be adjusted. And since the size of the connecting part 23 in the width of the second slide groove 212 is larger than the width of the second slide groove 212, the connecting part 23 can slide stably in the first slide groove 211 and will not accidentally enter the second slide groove 212 from the first slide groove 211, thereby causing a change in the movement direction of the product 5 under test.

[0066] In another embodiment of this utility model, when the second slide groove 212 is set as a mating groove and the first slide groove 211 is set as an idle groove, the connecting part 23 slides in conjunction with the second slide groove 212. At this time, the connecting part 23 slides along the extension direction of the second slide groove 212 so as to adjust the position of the product to be tested 5 in the third direction. Since the dimension of the connecting part 23 in the width direction of the first slide groove 211 is larger than the groove width of the first slide groove 211, the connecting part 23 can slide stably in the second slide groove 212 and will not accidentally enter the first slide groove 211 from the second slide groove 212, thereby causing a change in the movement direction of the product to be tested 5.

[0067] Of course, this utility model does not limit the specific intersection position of the first slide groove 211 and the second slide groove 212. In one embodiment of this utility model, the two ends of the two slide grooves 211 and 212 intersect each other; in another embodiment of this utility model, one end of one slide groove intersects the middle of the other slide groove; in yet another embodiment of this utility model, the middle of the two slide grooves intersect each other. Specifically, in actual installation, the appropriate position can be selected according to requirements.

[0068] In this embodiment, the middle part of the first slide groove 211 intersects with the middle part of the second slide groove 212, so that the first slide groove 211 and the second slide groove 212 form a "+" structure.

[0069] Furthermore, to prevent the movable seat 22 from causing the product under test 5 to rotate along the axis extending in the first direction when it is installed on the connecting part 23, thereby affecting the radio interference test results of the product under test 5, a limiting groove 221 is recessed on the end of the movable seat 22 facing the mounting bracket 21 corresponding to the connecting part 23. The limiting groove 221 is interference-fitted with the connecting part 23, and the connecting part 23 is used to restrict the rotation of the movable seat 22 along the axis extending in the first direction. In this way, by setting the limiting groove 221, the relative rotation between the connecting part 23 and the movable seat 22 is restricted, thereby ensuring the angle of the product under test 5 during the radio interference test, so that the product under test 5 can always be placed in the same position, and the direction of movement can be switched simply by adjusting the angle of the connecting part.

[0070] It is understood that this utility model does not limit the specific structural form of the limiting groove 221. In one embodiment of this utility model, the limiting groove 221 can be set as a rectangular groove, that is, the opening of the limiting groove 221 is rectangular. With this setting, when the limiting groove 221 and the connecting part 23 are in an interference fit, the groove wall of the limiting groove 221 can restrict the relative rotation of the connecting part 23 and the movable seat 22. In another embodiment of this utility model, the limiting groove 221 can be set as a circular groove, that is, the opening of the limiting groove 221 is circular. In this case, through the interference fit between the limiting groove 221 and the connecting part 23, the relative rotation of the connecting part 23 and the movable seat 22 can also be restricted by friction limiting and compression limiting.

[0071] In another embodiment of this utility model, the shape of the limiting groove 221 corresponds to the combined shape of the first sliding groove 211 and the second sliding groove 212 to form the first limiting groove 221 and the second limiting groove 221. Thus, when the connecting part 23 needs to slide with the first sliding groove 211, the other end of the connecting part 23 is press-fitted with the first limiting groove 221. When the connecting part 23 needs to slide with the second sliding groove 212, the other end of the connecting part 23 is press-fitted with the second limiting groove 221. This arrangement corresponds one-to-one, thereby restricting the relative rotation of the connecting part 23 and the movable seat 22.

[0072] It should also be noted that the present invention does not limit the specific structural form of the connecting part 23. In one embodiment of the present invention, the connecting part 23 can be configured as a connecting plate. The connecting plate has two oppositely arranged ends in the first direction. One end is interference-fitted with the limiting groove 221 to realize the connection between the connecting plate and the movable seat 22. The other end is slidably fitted with one of the first sliding groove 211 and the second sliding groove 212 to realize the movable connection between the connecting plate and the mounting bracket 21, and to realize the position adjustment of the product 5 to be tested in the second direction and the third direction.

[0073] In another embodiment of this utility model, the connecting part 23 includes a first plate segment 231 and a second plate segment 232 spaced apart along a first direction. The first plate segment 231 and the second plate segment 232 are connected by a transition post 233. With this configuration, the first plate segment 231 is interference-fitted with the limiting groove 221 to achieve a mating connection between the connecting part 23 and the movable seat 22. The second plate segment 232 is slidably fitted with one of the first sliding groove 211 and the second sliding groove 212 to achieve a movable connection between the connecting part 23 and the mounting bracket 21. Thus, the provision of the transition post 233 can increase the structural strength of the connecting part 23, thereby improving the structural stability of the connecting part 23 and ensuring the installation stability of the product to be tested 5 on the movable seat 22.

[0074] In another embodiment of this utility model, the connecting part 23 includes a first plate segment 231 and a second plate segment 232 spaced apart along a first direction. The first plate segment 231 and the second plate segment 232 are connected by a transition post 233. At this time, the first plate segment 231 is interference-fitted with the limiting groove 221 to realize the connection between the connecting part 23 and the movable seat 22. The second plate segment 232 and the transition post 233 are both slidably fitted with one of the first sliding groove 211 and the second sliding groove 212 to realize the movable connection between the connecting part 23 and the mounting bracket 21. In this way, the structural strength of the connecting part 23 can be enhanced, and the connection strength between the connecting part 23 and the mounting bracket 21 can be improved, so as to further improve the support capacity of the first position adjustment structure 2 for the product 5 to be tested, and thus improve the installation stability of the product 5 to be tested.

[0075] Accordingly, in order to enable both the second plate segment 232 and the transition post 233 to slide with either the first slide groove 211 or the second slide groove 212, in a further embodiment of this utility model, both the first slide groove 211 and the second slide groove 212 are countersunk grooves. The countersunk groove includes a first groove segment 213 and a second groove segment 214 arranged sequentially away from the connecting portion 23 along a first direction. The first groove segment 213 communicates with the second groove segment 214, and the width of the first groove segment 213 is greater than the width of the second groove segment 214. In this configuration, when the connecting part 23 is connected to the mounting bracket 21, the second plate segment 232 extends through the first groove segment 213 into the second groove segment 214 to slide with the second groove segment 214, and the adapter post 233 extends into the first groove segment 213 to slide with the first groove segment 213. In this way, the second plate segment 232 and the adapter post 233 can simultaneously slide with one of the first and second grooves 211 and 212, ensuring the stability of the connection between the connecting part 23 and the mounting bracket 21.

[0076] Please see Figure 5 To prevent the connecting part 23 from detaching from the first slide groove 211 or the second slide groove 212, which could cause the movable seat 22 carrying the product 5 to fall and damage the radio interference testing device 100 or even the product 5, in a further embodiment of this invention, the bottom of the second groove segment 214 is through-hole to form a hole 215, and the second plate segment 232 is at least partially exposed from the bottom of the second groove segment 214. In this case, the connecting part 23 also includes a fastener 234, which is provided on the mounting bracket 21 facing away from the movable seat 22 in the first direction. At one end, the fastener 234 is larger than the groove width of the second groove segment 214 in either the second direction or the third direction, and the fastener 234 is connected to the part of the second plate segment 232 exposed in the second groove segment 214. Thus, when the second plate segment 232 and the second groove segment 214 are in sliding engagement, the fastener 234 is simultaneously pressed against the mounting bracket 21. This fixes the second plate segment 232 and the adapter post 233 on the mounting bracket 21 to prevent the second plate segment 232 and the adapter post 233 from disengaging from the mounting bracket 21, which could cause the movable seat 22 and the product 5 to fall and be damaged.

[0077] It is understood that this utility model does not limit the specific cooperation form between the fastener 234 and the second plate segment 232. In one embodiment of the utility model, the fastener 234 and the second plate segment 232 can be detachably connected by bolts. In another embodiment of the utility model, the fastener 234 and the second plate segment 232 can be detachably connected by a first snap-fit. In other embodiments of the utility model, the fastener 234 and the second plate segment 232 can also be connected by other connection structures, as long as the connection form between the fastener 234 and the second plate segment 232 is detachable, so that the second plate segment 232 can switch between the first slide groove 211 and the second slide groove 212 after being disengaged from the fastener 234. In actual settings, the appropriate method can be selected according to requirements.

[0078] To ensure the ability of the movable seat 22 to fix the product 5 to be tested, in one embodiment of this utility model, the end of the movable seat 22 facing the second mounting part is provided with a plurality of abutment portions at intervals. The plurality of abutment portions are respectively used to abut against a plurality of side ends of the product 5 to be tested in the second direction and / or third direction, so as to jointly clamp the product 5 to be tested in the second direction and / or third direction. With this arrangement, the plurality of abutment portions abut against a plurality of side ends of the product 5 to be tested in the second direction and / or third direction, so as to achieve clamping and limiting of the product 5 to be tested, and to fix the movable seat 22 to the product 5 to be tested.

[0079] In one specific embodiment of this utility model, the plurality of abutting parts include an upper abutting part 222 and a lower abutting part 223 disposed along a third direction. The upper abutting part 222 is used to abut the upper end of the product to be tested 5 in the third direction, and the lower abutting part 223 is used to abut the lower end of the product to be tested 5 in the third direction. In this way, the product to be tested 5 is fixed by the joint clamping and limiting of the upper abutting part 222 and the lower abutting part 223.

[0080] In addition, please see Figure 6-8 This utility model does not limit the specific direction of movement of the second mounting part. In one embodiment of this utility model, the second mounting part is movable and adjustable in the first direction. In this way, the user can adjust the distance between the radio transmitter 4 and the product to be tested 5 by adjusting the position of the second mounting part in the first direction.

[0081] In another embodiment of the present invention, the second mounting part is movably adjustable in the second direction, so that the user can adjust the relative position and relative angle of the radio transmitter 4 and the product under test 5 in the second direction by adjusting the position of the second mounting part in the second direction.

[0082] In another embodiment of this utility model, the second mounting part is movably adjustable in the third direction, so that the user can adjust the relative position and relative angle of the radio transmitter 4 and the product under test 5 in the third direction by adjusting the position of the second mounting part in the third direction.

[0083] In one specific embodiment of this utility model, the second mounting part is movably adjustable in the first direction, the second direction, and the third direction, with each of the three directions intersecting in pairs. This configuration allows the second mounting part to move in the first, second, and third directions, adjusting the distance between the radio transmitter 4 and the product under test 5, while simultaneously adjusting the relative angle between them. This ensures that the radio wave anti-interference capability of the product under test 5 can be tested from multiple angles.

[0084] Similarly, it is understood that this utility model does not limit the specific structure of the second position adjustment structure 3. For example, in one embodiment of this utility model, the second position adjustment structure 3 can be set as a three-axis displacement structure. The three-axis displacement structure includes a first slide rail extending along a first direction, a second slide rail extending along a second direction and slidably disposed on the first slide rail along the first direction, a third slide rail extending along a third direction and slidably disposed on the second slide rail along the second direction, and a slider slidably disposed on the third slide rail along the third direction. The slider is fixedly connected to the radio transmitter 4. Thus, when the second slide rail moves along the first direction, the second slide rail can drive the third slide rail and the slider to move together in the first direction to realize the position adjustment of the radio transmitter 4 in the first direction. When the third slide rail moves along the second direction, the third slide rail can drive the slider to move together in the second direction, that is, the position adjustment of the radio transmitter 4 in the second direction can be realized. When the slider moves in the third direction, the slider can drive the radio transmitter 4 to move in the third direction to realize the position adjustment of the radio transmitter 4 in the third direction.

[0085] In another embodiment of this utility model, the second position adjustment structure 3 includes a support rod 31, a first adjustment rod 32, and a second adjustment rod 33. The support rod 31 extends along a third direction, and the first adjustment rod 32 extends along a second direction. The first adjustment rod 32 is connected to the support rod 31 through a first mating part 34. The first mating part 34 is movablely engaged with the support rod 31 in the third direction and with the first adjustment rod 32 in the second direction. The second adjustment rod 33 extends along a first direction and is connected to the first adjustment rod 32 through a second mating part 35. The second mating part 35 is movablely engaged with the first adjustment rod 32 in the second direction and with the second adjustment rod 33 in the first direction. The second adjustment rod 33 forms a second mounting part. With this configuration, when the position of the radio transmitter 4 in the third direction needs to be adjusted, the first mating part 34 drives the first adjusting rod 32 to move along the third direction relative to the support rod 31, thereby adjusting the position of the radio transmitter 4 in the third direction; when the position of the radio transmitter 4 in the second direction needs to be adjusted, the first adjusting rod 32 moves relative to the first mating part 34 in the second direction, and / or, the second mating part 35 drives the second adjusting rod 33 to move relative to the first adjusting rod 32 in the second direction, thereby adjusting the position of the radio transmitter 4 in the second direction; when the position of the radio transmitter 4 in the first direction needs to be adjusted, the second adjusting rod 33 moves relative to the second mating part 35 in the first direction, thereby indicating the position adjustment of the radio transmitter 4 in the first direction.

[0086] It should be noted that, in a specific embodiment of this utility model, in order to realize the movable cooperation of the first mating part 34, the support rod 31, and the first adjusting rod 32, the first mating part 34 can be configured as a first buckle. The first buckle has two first retaining rings, which are set at an angle. One first retaining ring is detachably connected to the support rod 31, and the other first retaining ring is detachably connected to the first adjusting rod 32.

[0087] To achieve a detachable connection between the first retaining ring and the support rod 31 or the first adjusting rod 32, in this invention, the first retaining ring is formed by two opposing retaining arms. The two retaining arms are respectively provided with first threaded holes 341. A fixing screw passes through the two first threaded holes 341 in sequence to engage with the two first threaded holes 341, thereby securing the first retaining ring to the support rod 31 or the first adjusting rod 32. By releasing the fixing screw from the threaded engagement of the two first threaded holes 341, the first retaining ring can be released from the support rod 31 or the first adjusting rod 32. At this time, the relative position of the first retaining ring and the support rod 31 or the first adjusting rod 32 can be adjusted.

[0088] Similarly, in a specific embodiment of this utility model, in order to realize the movable cooperation between the second mating part 35 and the first adjusting rod 32 and the second adjusting rod 33, the second mating part 35 can be configured as a second buckle. The second buckle has two second retaining rings, which are arranged at an angle. One second retaining ring is detachably connected to the first adjusting rod 32, and the other second retaining ring is detachably connected to the second adjusting rod 33.

[0089] To achieve a detachable connection between the second retaining ring and the first adjusting rod 32 or the second adjusting rod 33, in this invention, the second retaining ring is formed by two opposing retaining arms. Each retaining arm has a corresponding second threaded hole 351. A fixing screw passes through the two second threaded holes 351 in sequence to engage with them, thereby securing the second retaining ring to the first adjusting rod 32 or the second adjusting rod 33. By releasing the fixing screw from the threaded engagement of the two second threaded holes 351, the second retaining ring can be released from the first adjusting rod 32 or the second adjusting rod 33. At this point, the relative position of the second retaining ring and the first adjusting rod 32 or the second adjusting rod 33 can be adjusted.

[0090] Understandably, to further improve the position adjustment capability of the second position adjustment structure 3 for the radio transmitter 4, in another embodiment of this utility model, the support rod 31 is rotatably arranged along a third-direction axis. With this arrangement, the user can also drive the support rod 31 to rotate along the third-direction axis, thereby causing the first adjustment rod 32, the second adjustment rod 33, and the radio transmitter 4 to rotate along the third-direction axis, ultimately achieving adjustment of the distance and relative angle between the radio transmitter 4 and the product under test 5.

[0091] It should also be noted that since the second adjusting rod 33 is installed on the first adjusting rod 32 and is located on one side of the support rod 31, the support rod 31 is subjected to greater force on one side. In order to prevent the support rod 31 from tipping over, in a further embodiment of this utility model, the second position adjusting structure 3 also includes a first counterweight 321. The first counterweight 321 is disposed on the first adjusting rod 32 and is located on the side of the support rod 31 away from the second adjusting rod 33. In this way, the force on the support rod 31 on the opposite sides is balanced, so that the force on the support rod 31 is even and the support rod 31 is prevented from tipping over.

[0092] It should also be noted that the radio transmitter 4 is mounted on the second adjusting rod 33 and located on one side of the first adjusting rod 32. At this time, the first adjusting rod 32 is subjected to greater force on one side, which can also cause the support rod 31 to tip over. Therefore, in a further embodiment of this utility model, the second position adjustment structure 3 also includes a second counterweight 331. The second counterweight 331 is disposed on the second adjusting rod 33 and located on the side of the first adjusting rod 32 away from the radio transmitter 4. In this way, the setting of the second counterweight 331 can balance the force on the second adjusting rod 33 on the opposite sides, so that the second adjusting rod 33 is subjected to uniform force, thereby making the support rod 31 subjected to uniform force, and further preventing the support rod 31 from tipping over.

[0093] Meanwhile, the arrangement of the first counterweight 321 and the second counterweight 331 can also reduce the torsional stress on the first mating part 34 and the second mating part 35, thereby extending the service life of the second position adjustment structure 3.

[0094] To further improve the support stability of the second position adjustment structure 3, in another embodiment of this utility model, the second position adjustment structure 3 further includes a base 36, and a support rod 31 is disposed on the base 36. The base 36 can increase the contact area between the second position adjustment structure 3 and the support surface, thereby further improving the support stability of the position adjustment structure.

[0095] Similarly, the support stability of the second position adjustment structure 3 can be improved by lowering the center of gravity of the second position adjustment structure 3. For example, in another embodiment of this utility model, the second position adjustment structure 3 further includes a third counterweight 361. The peripheral side of the third counterweight 361 is threaded. Thus, the third counterweight 361 can be connected to the base 36 through the adjusting nut 362. The setting of the third counterweight 361 can increase the weight of the base 36, thereby lowering the center of gravity of the second position adjustment structure 3 and enhancing the support stability of the second position adjustment structure 3.

[0096] In a further embodiment of this utility model, the base 36 is provided with a through hole along a third direction, the lower end of the support rod 31 is provided with an internal thread groove, and the third counterweight 361 passes through the through hole to extend into the internal thread groove so as to be threadedly engaged with the internal thread groove. In this way, the setting of the third counterweight 361 can not only improve the support stability of the second position adjustment structure 3, but also further improve the connection stability between the support rod 31 and the base 36.

[0097] Furthermore, in one embodiment of this invention, the radio transmitter 4 includes an adapter 41 and a transmitter 42. The adapter 41 is mounted on a second mounting portion and is rotatably disposed at least partially along an axis extending in a first direction. The transmitter 42 is disposed on the rotatably disposed portion of the adapter 41 and is used to transmit radio waves to the product 5 under test. Thus, by rotating the transmitter 42, a portion of the adapter 41 can further adjust the angle of the radio waves transmitted by the transmitter 42 to the product 5 under test, thereby further improving the detection range of the radio wave resistance capability of the product 5 under test.

[0098] It is understood that the present invention does not limit the specific structural form of the adapter 41. In one embodiment of the present invention, the adapter 41 can be configured as a ball bearing, with one of the inner ring and the outer ring of the ball bearing connected to the second mounting part and the other connected to the launching part 42.

[0099] In another embodiment of this utility model, the adapter 41 includes a fixing member 411 and a rotating member 412. The fixing member 411 is fixedly connected to the second displacement structure, and a mating groove is recessed at one end facing the first position adjustment structure 2. The rotating member 412 has two opposing ends, one end of which extends into the mating groove from the groove opening and is rotatably engaged with the mating groove, and the other end is connected to the transmitting part 42. With this configuration, the interference fit between the rotating member 412 and the mating groove of the fixing member 411 ensures the installation stability of the transmitting part 42. At the same time, due to the rotatable engagement between the rotating member 412 and the mating groove, the ability of the transmitting part 42 to rotate along the axis extending in the first direction can be ensured, thereby ensuring the ability to adjust the angle of the radio waves emitted by the transmitting part 42.

[0100] In other embodiments of this utility model, the adapter 41 can also be configured in other structural forms, which can be selected according to the actual requirements.

[0101] Similarly, this utility model does not limit the specific form of the transmitter 42. In one embodiment of this utility model, the transmitter 42 can be configured as a wireless telegraph machine; in another embodiment of this utility model, the transmitter 42 can also be configured as a walkie-talkie.

[0102] Specifically, in this embodiment, the rotating member 412 is provided with a fixed box 43, the transmitting part 42 is configured as a walkie-talkie, the walkie-talkie is located in the fixed box 43, a talk switch 421 is provided on one side of the walkie-talkie, and the fixed box 43 is provided with a pressure block 431 corresponding to the talk switch 421. The pressure block 431 is movable in the direction of approaching or away from the talk switch 421. The user can operate the pressure block 431 to move the pressure block 431 closer to the talk switch 421 and press the talk switch 421 to start the walkie-talkie and enable the walkie-talkie to transmit radio waves.

[0103] Furthermore, in this embodiment, the fixing box 43 is provided with a threaded hole corresponding to the pressure block 431, and the fixing box 43 is also provided with a switch screw 432 corresponding to the threaded hole. The switch screw 432 is threadedly engaged with the threaded hole. When the switch screw 432 moves toward the inside of the fixing box 43, it can drive the pressure block 431 to move closer to the intercom switch 421. When the switch screw 432 moves toward the outside of the fixing box 43, it can drive the pressure block 431 to move away from the intercom switch 421.

[0104] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
