Description

Technical Field

[0001] This utility model relates to the field of antenna assembly technology, specifically to a square antenna clamping mechanism. Background Technology

[0002] Square antennas are a common type of antenna, typically used in wireless communication, radar, and satellite communication. They are simple in structure, easy to design and manufacture, and exhibit good radiation characteristics in certain frequency bands. Square antennas can take the form of microstrip antennas, patch antennas, or array antennas, and are widely used in mobile communication, Wi-Fi, Bluetooth, and other devices.

[0003] Square antennas need to remain stable during operation to avoid positional shifts caused by vibration or external forces, which would affect signal transmission quality. Utility Model Content

[0004] The purpose of this invention is to provide a square antenna clamping mechanism that can fix square antennas of different sizes to ensure signal transmission quality.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A square antenna clamping mechanism includes a base with a guide rail on the base. At least two sliding plates are slidably connected along the length of the guide rail. Each sliding plate has a clamping mechanism for clamping the upper and lower ends of the square antenna, and a pressing mechanism for preventing the square antenna from moving back and forth. Its functions are as follows: the clamping mechanism fixes the upper and lower ends of the square antenna, preventing it from wobbling up and down; the pressing mechanism prevents it from wobbling back and forth; and the guide rail and sliding plates allow the distance between the sliding plates to be adjusted according to the length of the square antenna, thereby adjusting the clamping position of the sliding plates along the antenna's length.

[0007] Furthermore, the clamping mechanism includes a fixed plate and a movable plate distributed along the width direction of the guide rail. The fixed plate is mounted on the sliding plate, and the movable plate and the sliding plate are connected by clamping bolts, which are arranged parallel to the width direction of the guide rail. The fixed plate and the sliding plate are integrally formed. Its function is that, by setting the clamping bolts, the distance between the movable plate and the fixed plate can be adjusted according to the width of the square antenna, thereby enabling the movable plate and the fixed plate to securely clamp the upper and lower ends of the square antenna.

[0008] Furthermore, the movable plate is provided with a movable rod that penetrates the sliding plate, the movable plate has a through hole for the clamping bolt to pass through, and the sliding plate has a threaded hole for threaded connection with the clamping bolt. Its function is to prevent the movable plate from rotating around the clamping bolt by means of the movable rod.

[0009] Furthermore, the movable rod is prism-shaped, and its extension direction is parallel to the width direction of the guide rail. Its function is to facilitate movement of the movable rod along its extension direction on the sliding plate through its shape design.

[0010] Furthermore, the movable plate and the fixed plate each have an extension plate extending towards each other at their ends away from the guide rail. The purpose of these extension plates is to prevent the square antenna from rotating about an axis parallel to the width direction of the guide rail.

[0011] Furthermore, the clamping mechanism includes a clamping bolt that passes through the extension plate and is threadedly connected to the extension plate. The clamping bolt is perpendicular to the end face of the sliding plate away from the guide rail. Its function is to prevent the square antenna from moving back and forth by means of the clamping bolt.

[0012] Furthermore, both the movable plate and the fixed plate are provided with parallel plates arranged parallel to the extension plate. The clamping mechanism also includes parallel bolts that pass through the parallel plates and are threadedly connected to them. The parallel bolts are arranged parallel to the clamping bolts. Their function is that, through the arrangement of the parallel bolts, they can be used in combination with the clamping bolts to clamp the directional antenna between the clamping bolts and the parallel bolts.

[0013] Furthermore, the distance between the extension plate and the parallel plate is greater than the thickness of the square antenna. This allows the square antenna to be placed between the extension plate and the parallel plate.

[0014] Furthermore, the clamping bolts and parallel bolts are staggered. That is, the clamping bolts and parallel bolts are not coaxial; specifically, they are parallel but not coaxial from a top-view perspective of the base. This design allows for the generation of a small torque at the stress points at both ends of the square antenna, improving its fixation and preventing movement along the guide rail. Simultaneously, fine-tuning the clamping bolts and parallel bolts ensures that the front of the square antenna is perpendicular to the test end during testing.

[0015] Furthermore, the sliding plate has a through hole for the guide rail to pass through, and the guide rail is bolted to the base. The sliding plate also has threaded holes for fixing the sliding plate to the guide rail using fixing bolts. The cross-section of the guide rail is the same as the cross-section of the through hole. Gaskets are provided at both ends and the middle of the guide rail and base to prevent the sliding plate from colliding with the base. The base is L-shaped and includes a support plate for supporting itself on a flat surface and a mounting plate for mounting the guide rail; the support plate and mounting plate are perpendicular to each other.

[0016] The beneficial effects of this utility model are:

[0017] 1. The clamping mechanism can fix the top and bottom ends of the square antenna to prevent it from swaying up and down; the pressing mechanism can prevent it from swaying back and forth; the guide rail and sliding plate can adjust the distance between the sliding plates according to the length of the square antenna, thereby adjusting the clamping position of the sliding plate in the direction of the antenna length.

[0018] 2. By designing the spatial relationship between the clamping bolts and the parallel bolts, a small torque can be generated between the stress points at the front and rear ends of the square antenna, improving the fixing effect of the square antenna and preventing the square antenna from moving along the length of the guide rail.

[0027] Example 1

[0028] A square antenna clamping mechanism, such as Figure 1 As shown, the device includes a base 1, on which a guide rail 2 is mounted. At least two sliding plates 3 are slidably connected along the length of the guide rail 2. Each sliding plate 3 has a clamping mechanism for holding the upper and lower ends of a square antenna, and a pressing mechanism for preventing the square antenna from moving back and forth. Its functions are as follows: the clamping mechanism fixes the upper and lower ends of the square antenna, preventing it from wobbling up and down; the pressing mechanism prevents it from wobbling back and forth; and the guide rail 2 and sliding plates 3 allow the distance between the sliding plates 3 to be adjusted according to the length of the square antenna, thereby adjusting the clamping position of the sliding plates 3 along the antenna's length.

[0029] Specifically, such as Figure 1 As shown, the clamping mechanism includes a fixed plate 4 and a movable plate 5 distributed along the width direction of the guide rail 2. The fixed plate 4 is mounted on the sliding plate 3, and the movable plate 5 is connected to the sliding plate 3 by clamping bolts 6, which are parallel to the width direction of the guide rail 2. The fixed plate 4 and the sliding plate 3 are integrally formed. Their function is to allow the distance between the movable plate 5 and the fixed plate 4 to be adjusted according to the width of the square antenna by using the clamping bolts 6, thereby enabling the movable plate 5 and the fixed plate 4 to securely clamp the upper and lower ends of the square antenna.

[0030] Specifically, such as Figure 1 As shown, the movable plate 5 is provided with a movable rod 7 that penetrates the sliding plate 3, such as... Figure 2 As shown, the movable plate 5 has a through hole 8 for the clamping bolt 6 to pass through, and the sliding plate 3 has a threaded hole 9 for threaded connection with the clamping bolt 6. Its function is to prevent the movable plate 5 from rotating around the clamping bolt 6 by means of the movable rod 7.

[0031] Specifically, such as Figure 1 As shown, the movable rod 7 is prismatic in shape, and its extension direction is parallel to the width direction of the guide rail 2. Its function is to facilitate the movement of the movable rod 7 along its own extension direction on the sliding plate 3 through its shape design.

[0032] Specifically, such as Figure 1 As shown, the movable plate 5 and the fixed plate 4 each have an extension plate 10 extending towards each other from the end away from the guide rail 2. The function of the extension plate 10 is to prevent the square antenna from rotating around an axis parallel to the width direction of the guide rail 2.

[0033] Specifically, such as Figure 1 As shown, the clamping mechanism includes a clamping bolt 11 that passes through and is threadedly connected to the extension plate 10. The clamping bolt 11 is perpendicular to the end face of the sliding plate 3 away from the guide rail 2. Its function is to prevent the square antenna from moving back and forth by setting the clamping bolt 11.

[0034] Specifically, such as Figure 1 As shown, both the movable plate 5 and the fixed plate 4 are provided with parallel plates 12 arranged parallel to the extension plate 10. The clamping mechanism also includes a parallel bolt 13 that passes through the parallel plate 12 and is threadedly connected to the parallel plate 12. The parallel bolt 13 is arranged parallel to the clamping bolt 11. Its function is that, through the arrangement of the parallel bolt 13, it can be used in combination with the clamping bolt 11 to clamp the directional antenna between the clamping bolt 11 and the parallel bolt 13.

[0035] Specifically, such as Figure 1 As shown, the distance between the extension plate 10 and the parallel plate 12 is greater than the thickness of the square antenna. Its function is to allow the square antenna to be placed between the extension plate 10 and the parallel plate 12.

[0036] Specifically, such as Figure 3 As shown, the clamping bolt 11 and the parallel bolt 13 are offset. That is, the clamping bolt 11 and the parallel bolt 13 are not coaxial. This design allows for the generation of a small torque at the stress points at both ends of the square antenna, improving the fixation of the square antenna and preventing it from moving along the length of the guide rail 2. Simultaneously, fine-tuning the clamping bolt 11 and the parallel bolt 13 ensures that the front of the square antenna is perpendicular to the test end during testing.

[0037] Specifically, such as Figure 1 As shown, the sliding plate 3 has a through hole 14 for the guide rail 2 to pass through, and the guide rail 2 is connected to the base 1 by bolts. The sliding plate 3 has threaded holes for fixing the sliding plate 3 to the guide rail 2 by fixing bolts. The cross-section of the guide rail 2 is the same as the cross-section of the through hole 14.

[0038] The working principle of this embodiment is explained as follows: First, the guide rail 2 is passed through the through hole 14, so that two sliding plates 3 are mounted on the guide rail 2. The bottom of the square antenna is placed on the fixed plate 4. Then, the movable rod 7 is passed through the sliding plate 3, and the clamping bolt 6 is passed through the movable plate 5 and threaded into the threaded hole 9, so that the movable plate 5 presses against the top of the square antenna. Finally, the clamping bolts 11 and parallel bolts 13 are tightened, so that all the clamping bolts 11 press against the front end face of the square antenna, and all the parallel bolts 13 press against the rear end face of the square antenna. Figure 4 As shown, this completes the fixing of the square bolts.

[0039] 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 way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
