DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] Reference Figures 1 to 3 The portable antenna provided in this embodiment includes two antenna units, a tripod, a base plate, a metal cloth and four retractable rods.

[0041] In this embodiment, the metal cloth is rectangular with a central rectangular defect. The baseplate is mounted at the location of the rectangular defect and bonded to the inner edge of the metal cloth. Four retractable rods correspond to the four corners of the metal cloth. One end of each rod rests against the corner of the metal cloth, and the other end connects to the edge of the baseplate, supporting the metal cloth. Both antenna units are mounted on the baseplate, and the metal cloth and baseplate together serve as the antenna reflector base for the antenna units.

[0042] The back of the base plate has a fixing bracket connected to the base plate via quick-lock fixing screws. The top of the tripod is connected to the fixing bracket for better support. The tripod of this embodiment was purchased directly and is not the focus of this patent, so the structure of the tripod will not be described in detail.

[0043] Reference Figure 10 and Figure 11 The bottom plate of this embodiment is divided into a left bottom plate and a right bottom plate. The left bottom plate and the right bottom plate are located in the same plane and are spliced together. The left bottom plate and the right bottom plate are each divided into two parts, one of which is a metal flat plate for mounting the corresponding antenna unit, and the other part is a fence structure for splicing; the fence structure of the left bottom plate is plugged into the fence structure of the right bottom plate, or the fence structure of the right bottom plate is plugged into the fence structure of the left bottom plate. The fence structure of this embodiment is a plurality of parallel fence bars arranged on one side of the metal flat plate, and there is a spacing between adjacent fence bars.

[0044] In this embodiment, a locking structure is provided at the end of the fence structure of the left bottom plate; the locking structure includes a locking bolt, an upper support bar and a lower support bar; the upper support bar and the lower support bar are respectively installed at the top and bottom of the left bottom plate fence structure, and are both perpendicular to the fence bars of the fence structure; the locking bolt is installed on the upper support bar and is threadedly connected to the upper support bar; the inner end of the locking bolt passes through the upper support bar and rests on the top of the fence bar of the right bottom plate fence structure.

[0045] In this embodiment, there is another method for fixing the two bottom plates: connecting through a fixing bracket on the back; connecting the fixing bracket through a quick-lock fixing screw at the corresponding position of each fence bar.

[0046] Reference Figure 9 and Figure 4 , the two antenna units of this embodiment include a matching plate, a connecting plate, a vibrator, a vertical pole, a supporting pole and a bead hinge;

[0047] The matching disk is located above the connecting disk, and the central axes of the two coincide with each other; the support rod is located between the matching disk and the connecting disk to connect the two; the vertical rod is located at the bottom of the connecting disk, and the bottom end of the vertical rod is fixed to the base plate. The four vibrators and the connecting disk are located in the same plane, and the four vibrators are arrayed along the circumference of the connecting disk. The four vibrators are divided into two parts, one part of which is installed on the connecting disk. The two parts of the vibrator are connected by a ball-bump hinge. When the ball-bump hinge is closed, the vibrator is electrically connected to the connecting disk. The ball-bump hinge in this embodiment was purchased directly and was not designed for this embodiment, so this patent will no longer describe the structure of the ball-bump hinge.

[0048] Reference Figures 5 to 9 The telescopic support rod used in this embodiment includes an operating rod, a fixed tube, and a positioning collar, with their central axes coinciding. One end of the positioning collar is a fixed tube connector for insertion into the open end of the fixed tube, while the other end is an operating rod connector. The operating rod is inserted into the connector and prevents it from falling out. One end of the rod passes through the positioning collar and is located in the fixed tube, allowing it to slide freely along the fixed tube.

[0049] The bottom of the positioning collar is provided with an open window; the U-shaped lock frame is located in the open window and passes through the positioning collar and is hinged to the eccentric column above the positioning collar. A pull block is provided on the side wall of the eccentric column.

[0050] When the length of the action rod needs to be adjusted, rotate the pull block upward to reduce the friction between the U-shaped lock frame and the action rod and adjust the length; rotate the pull block downward, and the U-shaped lock frame and the action rod are pressed tightly in the open window to achieve positioning locking.

[0051] In this embodiment, the portable antenna is composed of two antenna units. The antenna element of each antenna unit is foldable. In the deployed state, the antenna element is unfolded, and in the stored state, the antenna element is folded.

[0052] The metal base in the center area is divided into two parts, left and right. The two parts can be embedded in and separated from each other in the plane to realize the expansion and storage of the metal base;

[0053] The metal cloth is fixed to the metal base plate through a retractable support rod, and together with the metal base plate, it acts as an antenna reflection base plate.

[0054] The design principle of the portable antenna is:

[0055] (1) Fold down the antenna unit's vibrator, separate the bumper that fixes the vibrator, and rotate the vibrator along the bumper hinge, changing from a horizontally unfolded state to a vertically stored state;

[0056] (2) Adjust the telescopic support rod to the stowed state, and the metal cloth is folded along with the telescopic support rod;

[0057] (3) Remove the entire antenna from the tripod;

[0058] (4) Loosen the locking screws on the left and right bottom plates, and insert the two bottom plates into each other horizontally. The antenna units and retractable rods on the two bottom plates are close to each other, and the antenna is stored.

[0059] (5) Similarly, the antenna can be deployed by completing the deployment action in the reverse order.

[0060] It should be noted that the above description is only an example of a preferred application of the present invention and is not intended to limit the scope of protection of the present invention. Any technical solution that adopts equivalent replacement or equivalent transformation is within the scope of protection of the present invention.
