Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of antenna equipment and relates to a portable antenna equipment. BACKGROUND

[0002] The Yagi antenna is an end-fire antenna formed by parallel arrangement of an active oscillator, a passive reflector and a plurality of passive directors, and has the advantages of high gain, light structure and convenient erection. However, due to the structural reasons, the Yagi antenna needs to be matched with the active oscillator by a plurality of directors to work, and thus the length of the Yagi antenna is relatively long, which is inconvenient for carrying out. In addition, the directors and the active oscillator are prone to be bent during transportation, thereby affecting the signal transmission effect.

[0003] A portable high-gain antenna is disclosed in a patent document with the publication number CN116111365A, which includes a main rod, a director connected with the main rod, and a reflector installed at the tail of the main rod. The main rod is fixed with a parallel active oscillator between the reflector and the director. A first limiting slot is formed at the connection between the top shell of the active oscillator and the signal part. The first limiting slot is clamped with the director and the reflector. The first limiting slot of the top shell and the second limiting slot of the signal part form a cavity to accommodate the director and the reflector. After accommodation, the rotatable oscillator shell is rotated to make the three parts and the main rod uniformly oriented, so that the accommodation is more convenient. The director, the reflector and the oscillator are not prone to be damaged during transportation. The folding main rod is smaller in size than the traditional integrated antenna and is more portable.

[0004] However, when the antenna is accommodated, the director and the reflector need to be extracted, then the top shell is opened, the director and the reflector are installed in the slot body, and then the top shell is buckled. Then, the signal part is separated from the embedded column at the top of the seat body through the installation slot at the bottom of the oscillator, and the direction of the oscillator and the rod body is changed. Then, the rod body is folded. The accommodation box has many installation operation steps and low efficiency.

[0045] Working principle:

[0046] As Figure 1The folding storage state of the device is shown. The linkage mechanism is between the first housing 2 and the second housing 4, and the telescopic mechanism is in the shortened state. On the second side of the I-shaped frame 3, in the same linkage mechanism, the first rotating rod 18, the second rotating rod 19, the first guide 15 and the second guide 16 are parallel to each other, the two first rotating rods 18 are in the same straight line, the two second rotating rods 19 are in the same straight line, and the first guide 15 and the second guide 16 are between the corresponding first rotating rod 18 and the second rotating rod 19 and between the corresponding two U-shaped frames 25. The first guide 15 is in a protected state to prevent the first guide 15 from being bent. On the first side of the I-shaped frame 3, the two third rotating rods 20 are in the same straight line, the two fourth rotating rods 21 are in the same straight line, the third rotating rod 20, the fourth rotating rod 21 and the reflector 22 are parallel to each other, and the reflector 22 is between the third rotating rod 20 and the fourth rotating rod 21. The third rotating rod 20 and the fourth rotating rod 21 have a protective effect on the reflector 22. In the storage state, it is convenient to carry, and during transportation, the first guide 15, the second guide 16 and the reflector 22 are all in a protected state to prevent the first guide 15, the second guide 16 and the reflector 22 from being deformed.

[0047] When it is needed to be unfolded for use, the first threaded rod 7 is screwed to make the stop rod 8 move downward to release the limiting of the rear connecting frame 29.

[0048] The front connecting frame 28 is pulled to move the front connecting frame 28 forward. In the first linkage mechanism, the front connecting frame 28 pulls one end of the second rotating rod 19 to move forward, the second rotating rod 19 rotates outward of the U-shaped frame 25, the two U-shaped frames 25 approach each other and move forward at the same time, the U-shaped frame 25 drives one end of the first rotating rod 18 to move forward, the first rotating rod 18 rotates outward of the U-shaped frame 25, the first rotating rod 18 and the second rotating rod 19 gradually change to the direction perpendicular to the first guide 15, the two second rotating rods 19 gradually overlap together, and the two first rotating rods 18 gradually fold together.

[0049] As Figure 5As shown, the first rotating rod 18 in the first linkage mechanism drives the first gear 23 to rotate clockwise, and the first gear 23 drives the second gear 24 in the second linkage mechanism to rotate counterclockwise. In the second linkage mechanism, the second gear 24 drives the second rotating rod 19 to rotate counterclockwise around the axis of the second gear 24, thereby moving the middle connecting frame 27 between the first linkage mechanism and the second linkage mechanism forward, and correspondingly moving the second guide 16 forward. The middle connecting frame 27 between the first linkage mechanism and the second linkage mechanism drives the second linkage mechanism to move, and the first rotating rod 18 and the second rotating rod 19 in the second linkage mechanism are both rotated outward of the U-shaped frame 25. When the first rotating rod 18 in the second linkage mechanism rotates, it drives the corresponding first gear 23 to rotate clockwise, and the corresponding second gear 24 to rotate counterclockwise, thereby driving the corresponding second rotating rod 19 in the third linkage mechanism to rotate counterclockwise, and moving the middle connecting frame 27 between the second linkage mechanism and the third linkage mechanism forward, and correspondingly moving the second guide 16 forward. The first rotating rod 18 and the second rotating rod 19 in the third linkage mechanism are both rotated outward of the corresponding U-shaped frame 25, and gradually change to the direction perpendicular to the first guide 15.

[0050] When the first rotating rod 18 in the third linkage mechanism is rotated outward of the U-shaped frame 25, it drives the first gear 23 on the work-shaped frame 3 to rotate clockwise, and the second gear 24 on the work-shaped frame 3 to rotate counterclockwise, thereby driving the corresponding third rotating rod 20 to rotate counterclockwise around the axis of the second gear 24. Due to the limiting of the work-shaped frame 3, the two U-shaped frames 25 move backward while approaching each other, and the rear connecting frame 29 moves backward. The third rotating rod 20 and the fourth rotating rod 21 gradually change to the direction perpendicular to the reflector 22. The U-shaped frame 25 moves backward to drive the reflector 22 to move backward, and the reflector 22 gradually moves away from the second shell 4. The reflector 22 pulls the sliding block 31 through the slide rod 32, and the sliding block 31 slides along the sliding groove 30.

[0051] In the first linkage mechanism, the second linkage mechanism and the third linkage mechanism, when the corresponding two U-shaped frames 25 approach each other, the U-shaped frame 25 slides along the first guide 15 through the through hole 33, while the U-shaped frame 25 drives the first guide 15 to move forward, and the distance between the first guide 15 and the second guide 16 gradually increases, until the two U-shaped frames 25 abut against each other, the corresponding two first rotating rods 18 are superimposed together, and the corresponding two second rotating rods 19 are superimposed together, and the first rotating rod 18 and the second rotating rod 19 have a supporting effect on the first guide 15 and the second guide 16. In the fourth linkage mechanism, when the two U-shaped frames 25 approach each other, the U-shaped frame 25 slides along the reflector 22 through the through hole 33, until the two U-shaped frames 25 abut against each other, the two third rotating rods 20 are superimposed together, and the two fourth rotating rods 21 are superimposed together, and the third rotating rod 20 and the fourth rotating rod 21 have a supporting effect on the reflector 22. The device is in an unfolded state, as shown inFigure 7 As shown, then twist the second threaded rod 36, make one end of the second threaded rod 36 into the second fixed block 35, the two U-shaped frame 25 in the first connecting rod mechanism is fixed together, and then the device in the unfolded state is locked,

[0052] Four connecting rod mechanisms move simultaneously, and the device can be quickly unfolded.

[0053] When it needs to be stored, twist the second threaded rod 36, make the second threaded rod 36 from the second fixed block 35 out. Then, push the front connecting frame 28 to the direction of the second shell 4. On the second side of the I-shaped frame 3, the two second rotating rods 19 in the same connecting rod structure are gradually unfolded, the two first rotating rods 18 are gradually unfolded, and the first rotating rod 18 and the second rotating rod 19 are gradually changed to the state parallel to the first guide 15. At the same time, the two U-shaped frames 25 gradually move away, and the U-shaped frame 25 slides outward along the first guide 15. The U-shaped frame 25 and the middle connecting frame 27 gradually move to the direction of the second shell 4, the telescopic mechanism gradually contracts, the first guide 15 and the second guide 16 gradually move to the direction of the second shell 4, and the distance between the first guide 15 and the second guide 16 gradually decreases.

[0054] At the same time, when the two first rotating rods 18 in the third connecting rod mechanism rotate, the first gear 23 on the I-shaped frame 3 rotates, the second gear 24 on the I-shaped frame 3 rotates, the fourth connecting rod mechanism moves, the two third rotating rods 20 gradually unfold and change to the state parallel to the reflector 22, the two fourth rotating rods 21 gradually unfold and change to the direction parallel to the reflector 22, the two U-shaped frames 25 gradually move away, and the U-shaped frame 25 and the reflector 22 move to the direction of the second shell 4 until the device returns to the storage state.

[0055] Then twist the first threaded rod 7, move the stop rod 8 upward, and the stop rod 8 limits the rear connecting frame 29 to prevent the device from being opened accidentally.

[0056] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
