Description

Technical Field

[0001] The present invention relates to the technical field of shortwave broadband antennas, in particular to a foldable three-wire shortwave broadband antenna. Background Art

[0002] A three-wire shortwave antenna is a multi-conductor antenna designed specifically for shortwave communications (3-30 MHz). It is renowned for its broadband characteristics and structural flexibility. In the shortwave communications field, three-wire antennas are widely used for their excellent communication performance, ease of installation, and high cost-effectiveness. They are currently one of the main shortwave antenna types both domestically and internationally.

[0003] Patent number CN205680789U discloses an integrated shortwave three-wire antenna, comprising a sealed strip box and a matching magnetic ring coil and a non-inductive absorption resistor installed in the sealed strip box. Six oscillator cables extend from the four corners and the middle of the sealed strip box, and three supporting insulating rods are provided between the three parallel oscillator wires on both sides of the box. The entire antenna of the present invention is no longer composed of separate components but is integrated into a whole, avoiding the entanglement, knotting, and damage of the oscillator wires and other components that are prone to occur during the installation and collection of three-wire antennas with conventional structures. The sealed box and the oscillator wires wrapped in a protective outer sheath are moisture-proof, rain-proof, and salt spray-resistant, meeting the requirements of use in various harsh environments in the field, both on land and at sea. In addition to the only flat-pull installation method of ordinary three-wire antennas, an inverted triangle installation method is added to increase its scope of application and facilitate the diversification of communication applications.

[0004] The above patent has the following problems: In the prior art, since the insulating rod does not have a folding function, it occupies a large space and is inconvenient to store and transport the insulating rod. Therefore, we have introduced a foldable three-wire shortwave broadband antenna. Summary of the Invention

[0005] The object of the present invention is to provide a foldable three-wire shortwave broadband antenna, which can be easily folded, has high folding efficiency, reduces the labor intensity of the staff, occupies less space when stored and transported, and improves the convenience of transportation, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: A foldable three-wire shortwave broadband antenna includes a pull wire, an insulating rod, an antenna vibrator and a matching box. Multiple insulating rods are evenly arranged on the pull wire, the matching box is arranged below the pull wire, the antenna vibrator is arranged between the matching box and the pull wire, and a radio frequency cable is provided at the bottom of the matching box. The number of pull wires is set to three. The insulating rod includes a middle rod and two folding rods. The two ends of the middle rod are rotatably connected to the ends of the folding rods by hinges. The lower rod wall of the middle rod and the ends of the two folding rods are fixed with positioning rings. The three pull wires pass through the three positioning rings respectively. The interior of the middle rod is hollow, and a first locking mechanism is provided between the inner side of the middle rod and the two folding rods.

[0007] As a further solution of the present invention, the locking mechanism includes two locking rods, two push rods and a spring. The two locking rods are respectively slidably arranged on both sides of the middle rod, and the opposite ends of the two locking rods extend to the outside of the middle rod. The end of the folding rod is provided with a locking groove that cooperates with the locking rod. A spring is fixed between the two folding rods. The rod wall of the folding rod is provided with a push rod. The side wall of the middle rod is provided with a first strip hole that cooperates with the push rod. A second locking mechanism is provided between the upper rod wall of the folding rod and the middle rod.

[0008] As a further solution of the present invention, the second locking mechanism includes a slider, which is fixedly arranged on the upper rod wall of the push rod, and a second strip hole that cooperates with the slider is provided on the upper side of the middle rod. The upper end of the slider extends to the outside of the middle rod, and the upper end side wall of the slider is provided with a card hole. A card rod is provided for sliding in the card hole, and the two opposite sides of the card rods extend to the outside of the external sliding hole and are fixedly connected to the folding rod.

[0009] As a further solution of the present invention, a push plate is fixedly provided at one end of the push rod located outside the middle rod.

[0010] As a further solution of the present invention, the spring is always in a compressed state.

[0011] As a further solution of the present invention, the clamping rod is configured to be L-shaped.

[0012] As a further solution of the present invention, the ends of the two locking rods facing away from each other are both chamfered.

[0013] As a further solution of the present invention, the chamfer angle is set to 45°.

[0014] As a further solution of the present invention, one end of the clamping rod is configured as a round head.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When the folding rod is rotated 180 degrees around the hinge, the two folding rods are located on the upper side of the middle rod. At this time, the push plate is pushed, and the push plate drives the locking rod to squeeze the spring through the push rod, and the locking rod drives the slider to move. When the position of the clamping rod corresponds to the clamping hole, the push plate is released, the spring pushes the locking rod to move, and the locking rod drives the slider to move, and the clamping rod is clamped into the inside of the clamping hole. The locking rod locks the folding rod through the slider and the clamping rod. At this time, the folding is completed, and the broadband antenna can be conveniently folded. The folding efficiency is high, the labor intensity of the staff is reduced, the space occupied during storage and transportation is small, and the convenience of transportation is improved.
