Description

Technical Field

[0001] This utility model relates to the field of antenna testing auxiliary equipment technology, and in particular to a fixed device based on antenna testing and its dedicated vehicle. Background Technology

[0002] The purpose of antenna testing is a crucial step to ensure excellent antenna performance and reliable signal transmission. This involves measuring key indicators such as antenna radiation efficiency, frequency response, gain, polarization characteristics, and VSWR. Currently, antenna testing utilizes specialized vehicles to transport the antenna to a specific location for testing; therefore, the antenna needs to be placed on these specialized vehicles.

[0003] Currently, the antenna is placed horizontally on the special vehicle. However, due to the lack of effective fixation, the antenna may become misaligned or loose relative to the special vehicle when the vehicle encounters road conditions such as gravel roads or non-grade highways, resulting in collisions and damage. Utility Model Content

[0004] The technical problem this invention aims to solve is: to address the issue that existing horizontal antenna placement methods easily lead to antenna misalignment or loosening relative to the vehicle, resulting in collisions and damage. This invention provides a fixing device and its corresponding vehicle for antenna testing. By improving the antenna placement method, the antenna is fixed in place, ensuring that it will not misalign or loosen relative to the rotating vehicle, thereby improving the stability of the antenna during placement and reducing the risk of antenna damage.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a fixing device based on antenna testing, the fixing device is installed on a special vehicle body, the fixing device includes: a fixing part, a driving part and a first clamping part, the fixing part is installed on one side of the special vehicle body, the antenna to be tested is located in the special vehicle body, the driving part passes through the fixing part and is threadedly connected to the fixing part, the driving end of the driving part is rotatably connected to the first clamping part, the first clamping part is located on the side closer to the antenna; wherein: when the driving part drives the first clamping part to move towards the side closer to the antenna and the first clamping part abuts against the antenna, the first clamping part is used to clamp and fix the antenna.

[0006] Therefore, by driving the first clamping part through the driving part to achieve the clamping fixation of the antenna, compared with the existing method of simply placing the antenna, the clamping fixation method can ensure that during the antenna transportation process, the antenna will not be misaligned or loosened relative to the special vehicle body due to encountering gravel roads, non-grade roads, etc., which would cause the antenna to collide with the special vehicle body, thereby improving the stability of the antenna during placement and reducing the risk of the antenna being damaged by collision.

[0007] As a further improvement to the above technical solution: the fixing part includes a first fixing frame and a second fixing frame, the first fixing frame being connected to the second fixing frame, and the first fixing frame being located on the side of the second fixing frame away from the first pressing part. Both the first fixing frame and the second fixing frame are connected to the special vehicle body; the driving part passes through the first fixing frame and is threadedly connected to the first fixing frame. Thus, since both the first fixing frame and the second fixing frame are connected to the special vehicle body, the stability of the entire fixing device installation can be improved, further enhancing the firmness of the antenna pressing-type fixing.

[0008] As a further improvement to the above technical solution: the first fixing frame is provided with a first fixing block, and the driving part passes through the first fixing block and is threadedly connected to the first fixing block.

[0009] As a further improvement to the above technical solution, it also includes: a second clamping part, which is located between the first fixing frame and the second fixing frame and connected to the second fixing frame; the driving part passes through one end of the second clamping part and is threadedly connected to the second clamping part; the other ends of the first clamping part and the second clamping part are slidably connected. Thus, by using the second clamping part located between the first fixing frame and the second fixing frame, and in cooperation with the first clamping part, a double-clamping fixation of the antenna can be achieved, further improving the antenna's fixing effect.

[0010] As a further improvement to the above technical solution: the second clamping part includes a second fixing block and a clamping rod. The driving part passes through the second fixing block and is connected to the second fixing block. One end of the clamping rod is connected to the second fixing block, and the other end of the clamping rod is slidably connected to the first clamping part. The clamping rod is also connected to the second fixing frame. Therefore, by using the design of the other end of the clamping rod being slidably connected to the first clamping part and the clamping rod being connected to the second fixing frame, when the second fixing frame is connected to the special vehicle body, when the driving part rotates, it will drive the second fixing block, the clamping rod, and the first clamping part to move towards or away from the antenna. This achieves a double clamping fixation of the first and second clamping parts. Furthermore, this method ensures that during the rotation of the driving part, the clamping rod ensures that the first clamping part only moves towards or away from the antenna and does not rotate with the rotation of the driving part. This avoids damage to the antenna caused by the clamping fixation due to the rotation of the first clamping part.

[0011] As a further improvement to the above technical solution: multiple clamping rods are provided, and the multiple clamping rods are distributed in a ring shape with equal spacing. Therefore, the multiple clamping rods distributed in a ring shape with equal spacing can apply pressure evenly to the first clamping part, ensuring that the clamping force at each position of the first clamping part is consistent, resulting in a better antenna clamping and fixing effect and a more secure antenna fixation.

[0012] As a further improvement to the above technical solution: a turntable is provided on the side of the driving unit away from the first clamping unit. Therefore, rotation of the driving unit facilitates rotation operation, thereby facilitating the clamping fixation of the antenna.

[0013] As a further improvement to the above technical solution, a rubber pad is provided on the side of the first clamping part away from the fixing part. This rubber pad ensures that the first clamping part does not directly contact the antenna, thus preventing damage to the antenna from the first clamping part.

[0014] A special vehicle includes: an antenna-based testing fixing device, a special vehicle body, and a support block. The antenna-based testing fixing device is installed on one side of the special vehicle body and is used to press-fit an antenna. The support block is connected to the special vehicle body and is used to support the antenna.

[0015] As a further improvement to the above technical solution: the special vehicle body has an installation slot, the support block is located on the special vehicle body, and the antenna is placed in the installation slot.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves antenna clamping fixation by driving the first clamping part through the driving part. Compared with the existing method of simply placing the antenna, the clamping method of fixing the antenna can ensure that during the antenna transportation process, the antenna will not be misaligned or loosened relative to the special vehicle body due to encountering gravel roads, non-grade roads, etc., which would cause the antenna to collide with the special vehicle body. This improves the stability of the antenna during placement and reduces the risk of antenna damage due to collision.

[0017] 2. This utility model, by providing a second clamping part between the first fixing frame and the second fixing frame, and in cooperation with the first clamping part, can achieve double clamping fixation of the antenna, thereby further improving the antenna fixing effect.

[0018] 3. This utility model uses a design where the other end of the clamping rod is slidably connected to the first clamping part, and the clamping rod is connected to the second fixing frame. When the second fixing frame is connected to the special vehicle body, the rotation of the drive unit will drive the second fixing block, the clamping rod, and the first clamping part to move towards or away from the antenna. In this way, a double clamping fixation of the first clamping part and the second clamping part can be achieved. In addition, during the rotation of the drive unit, the clamping rod can ensure that the first clamping part will only move towards or away from the antenna and will not rotate with the rotation of the drive unit. Thus, damage to the antenna caused by the clamping fixation due to the rotation of the first clamping part can be avoided.

[0019] 4. The multiple clamping rods of this utility model are distributed in a ring at equal intervals, which can apply pressure evenly to the first clamping part to ensure that the clamping force at each position of the first clamping part is consistent, resulting in a better antenna clamping and fixing effect and a more secure antenna fixation.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1 to 2As shown, a fixing device for antenna testing is installed on a special vehicle body 1. The fixing device includes a fixing part 2, a driving part 3, and a first clamping part 4. The fixing part 2 is installed on one side of the special vehicle body 1, and the antenna to be tested is located inside the special vehicle body 1. The driving part 3 passes through the fixing part 2 and is threadedly connected to the fixing part 2. The driving end of the driving part 3 is rotatably connected to the first clamping part 4, which is located on the side closer to the antenna. When the driving part 3 drives the first clamping part 4 to move towards the side closer to the antenna and the first clamping part 4 abuts against the antenna, the first clamping part 4 is used to clamp the antenna. Thus, by driving the first clamping part 4 through the driving part 3, the antenna is clamped and fixed. Compared with the existing method of simply placing the antenna, the clamping method of fixing the antenna can ensure that during the antenna transportation process, it will not be misaligned or loosened relative to the special vehicle body 1 due to encountering gravel roads, non-grade roads, etc., which would cause the antenna to collide with the special vehicle body 1. This improves the stability of the antenna during placement and reduces the risk of damage to the antenna due to collision.

[0027] For example, drive unit 3 uses a threaded rod.

[0028] In this embodiment, the fixing part 2 includes: a first fixing frame 201 and a second fixing frame 202. The first fixing frame 201 is connected to the second fixing frame 202, and the first fixing frame 201 is located on the side of the second fixing frame 202 away from the first pressing part 4. Both the first fixing frame 201 and the second fixing frame 202 are connected to the special vehicle body 1. The driving part 3 passes through the first fixing frame 201 and is threadedly connected to the first fixing frame 201. The first fixing frame 201 is provided with a first fixing block 203, and the driving part 3 passes through the first fixing block 203 and is threadedly connected to the first fixing block 203. Thus, since both the first fixing frame 201 and the second fixing frame 202 are connected to the special vehicle body 1, the stability of the entire fixing device installation can be improved, thereby further enhancing the firmness of the antenna pressing fixation.

[0029] In this embodiment, it further includes: a second pressing part 5, which is located between the first fixing frame 201 and the second fixing frame 202 and is connected to the second fixing frame 202; a driving part 3 passes through one end of the second pressing part 5 and is threadedly connected to the second pressing part 5; and a first pressing part 4 is slidably connected to the other end of the second pressing part 5. The second pressing part 5 includes: a second fixing block 501 and a pressing rod 502; the driving part 3 passes through the second fixing block 501 and is connected to the second fixing block 501; one end of the pressing rod 502 is connected to the second fixing block 501; the other end of the pressing rod 502 is slidably connected to the first pressing part 4; and the pressing rod 502 is connected to the second fixing frame 202. A plurality of pressing rods 502 are provided, and the plurality of pressing rods 502 are distributed in a ring shape with equal spacing. Therefore, by using the second clamping part 5 provided between the first fixing frame 201 and the second fixing frame 202, and in cooperation with the first clamping part 4, a double clamping fixation of the antenna can be achieved, thereby further improving the antenna's fixing effect. Through the design of the other end of the clamping rod 502 slidingly connected to the first clamping part 4 and the clamping rod 502 connected to the second fixing frame 202, when the second fixing frame 202 is connected to the special vehicle body 1, when the drive unit 3 rotates, it will drive the second fixing block 501, the clamping rod 502, and the first clamping part 4 to move towards or away from the antenna. This design achieves dual clamping fixation with the first clamping part 4 and the second clamping part 5. Furthermore, during the rotation of the drive part 3, the clamping rods 502 ensure that the first clamping part 4 only moves towards or away from the antenna, and does not rotate with the drive part 3. This prevents damage to the antenna caused by the clamping fixation due to the rotation of the first clamping part 4. The multiple clamping rods 502, which are distributed in an evenly spaced ring, can apply pressure evenly to the first clamping part 4, ensuring that the clamping force at each position of the first clamping part 4 is consistent. This results in a better clamping fixation effect and a more secure antenna fixation.

[0030] In this embodiment, a turntable 301 is provided on the side of the drive unit 3 away from the first clamping unit 4. Therefore, rotation of the drive unit 3 facilitates rotation operation, thereby enabling the antenna to be clamped and fixed.

[0031] In this embodiment, a rubber pad 401 is provided on the side of the first pressing part 4 away from the fixing part 2. Therefore, the rubber pad 401 ensures that the first pressing part 4 does not directly contact the antenna, thus preventing damage to the antenna from the first pressing part 4.

[0032] like Figure 3As shown, a special vehicle includes: an antenna-based testing fixing device, a special vehicle body 1, and a support block 6. The antenna-based testing fixing device is installed on one side of the special vehicle body 1 and is used to press and fix the antenna. The support block 6 is connected to the special vehicle body 1 and is used to support the antenna.

[0033] In this embodiment, the special vehicle body 1 has a mounting slot 101, the support block 6 is located in the special vehicle body 1, and the antenna is placed in the mounting slot 101.

[0034] The antenna fixing process of this utility model is as follows: First, the antenna to be fixed is placed in the mounting groove 101 and supported by the support block 6, so that the side of the antenna away from the fixing device abuts against the special vehicle body 1; finally, the drive unit 3 is rotated by the turntable 301 so that the first pressing part 4 and the pressing rod 502 move towards the side closer to the antenna so that the rubber pad 401 abuts against the antenna. The antenna is double-pressed and fixed by the first pressing part 4 and the pressing rod 502, so that the antenna can be fixed by pressing.

[0035] In summary, this utility model achieves antenna clamping fixation by driving the first clamping part 4 through the driving part 3. Compared with the existing method of simply placing the antenna, the clamping method of fixing the antenna can ensure that during the antenna transportation process, the antenna will not be misaligned or loosened relative to the special vehicle body 1 due to encountering gravel roads, non-grade roads, etc., which would cause the antenna to collide with the special vehicle body 1. This improves the stability of the antenna during placement and reduces the risk of damage to the antenna due to collision.

[0036] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
