Description

Technical Field

[0001] The present invention relates to the technical field of whip antennas, and specifically to a foldable whip antenna. Background Art

[0002] Whip antennas are widely used in mobile communication, amateur radio, vehicle communication, emergency communication and other fields because of their simple structure, convenient installation and excellent signal receiving and transmitting performance in specific frequency bands. However, most traditional whip antennas are of rigid structure. Although they have certain advantages in terms of stable performance, with the increasing requirements for equipment portability and space utilization efficiency, their fixed shape and large size have become obvious limitations. In situations where the equipment needs to be frequently moved, stored or the installation space is limited, such as in field operation scenarios, traditional rigid whip antennas are not only inconvenient to carry, but also occupy too much space, affecting the operation efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a foldable whip antenna to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A foldable whip antenna, including a mounting base, on which a plurality of antenna rods are sequentially arranged, and a rotating mechanism for folding the antenna rods is arranged between every two adjacent antenna rods; A limiting mechanism for locking between two antenna rods is arranged on the rotating mechanism, and a clamping component for limiting the folded antenna rods is arranged on the antenna rods; The rotating mechanism includes a second mounting base at the lower end of the upper antenna rod and a first mounting base at the upper end of the lower antenna rod, and the first mounting base and the second mounting base are rotatably connected by a rotating member; the limiting mechanism can lock between the first mounting base and the second mounting base.

[0005] Preferably, the rotating member includes a connecting folding plate fixedly installed on the second mounting base and a fixing block fixedly installed on the first mounting base, and a rotating shaft is fixedly installed on the connecting folding plate and is rotatably connected to the fixing block.

[0006] Preferably, the limiting mechanism includes a limiting seat and a fixing support plate fixedly installed on the first mounting base, a groove is arranged in the middle of the limiting seat, and a limiting rod is fixedly connected to the lower end of the fixing support plate.

[0007] Preferably, a moving slide plate is slidably connected to the limiting rod, hinge connecting plates are hinged to both ends of the moving slide plate, and a limiting slide plate is hinged to the end of the hinge connecting plate far away from the moving slide plate.

[0008] Preferably, the limit slide plate is slidably connected to the limit seat, a connecting spring is sleeved on the limit rod, one end of the connecting spring is fixedly connected to the fixed support plate, and the other end of the connecting spring is fixedly connected to the moving slide plate.

[0009] Preferably, the limiting mechanism further includes a connecting fixed block fixedly installed on the second mounting seat, and a fixing plate is fixedly installed on the connecting fixed block.

[0010] Preferably, a limit insertion hole for the limit slide plate to extend into is formed on the fixing plate, and the fixing plate can be rotated into the groove.

[0011] Preferably, the clamping assembly includes a connecting block fixedly installed on the antenna rod, elastic clamping plates are symmetrically arranged on the connecting block, a buffer pad is fixedly connected to the connecting block, and the two elastic clamping plates are used for clamping and limiting the folded antenna rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the antenna needs to be folded, by pushing the moving slide plate upward, the moving slide plate slides on the limit rod and squeezes the connecting spring, so that the moving slide plate moves upward. During this process, the moving slide plate drives the two limit slide plates to move away from each other through the hinged connecting plate, and then drives the two limit slide plates to move out of the two limit insertion holes respectively, thereby releasing the restriction on the second mounting seat. The operation of unlocking the limiting mechanism is simple and convenient. Only by pushing the moving slide plate upward can the unlocking action be completed, reducing the operation difficulty and improving the efficiency of antenna folding, which provides convenience for users to quickly adjust the antenna form during actual use.

[0013] 2. After releasing the restriction on the second mounting seat, the second mounting seat can be rotated, so that the rotating shaft rotates on the first mounting seat. When the antenna rod on the second mounting seat rotates to the lower elastic clamping plate, the two elastic clamping plates limit and fix the antenna rod. The design of the elastic clamping plate can make full use of its own elastic deformation ability to tightly clamp the antenna rod, ensuring the stability of the folded antenna rod, avoiding damage to the antenna caused by shaking or other reasons in the folded state, effectively improving the service life and reliability of the antenna, and at the same time enabling the antenna to maintain a compact form after folding, which is convenient for storage and carrying.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 6, the present invention provides a technical solution: a foldable whip antenna, which includes a mounting base 1. A plurality of antenna rods 2 are sequentially arranged on the mounting base 1. A rotating mechanism for folding the antenna rods 2 is arranged between every two adjacent antenna rods 2; a limiting mechanism 5 for locking between the two antenna rods 2 is arranged on the rotating mechanism, and a clamping component 6 for limiting the folded antenna rods 2 is arranged on the antenna rods 2; the rotating mechanism includes a second mounting base 4 at the lower end of the upper antenna rod 2 and a first mounting base 3 at the upper end of the lower antenna rod 2, and the first mounting base 3 and the second mounting base 4 are rotatably connected through a rotating member; the limiting mechanism 5 can lock between the first mounting base 3 and the second mounting base 4. The rotating member includes a connecting folding plate 7 fixedly installed on the second mounting base 4 and a fixing block 9 fixedly installed on the first mounting base 3. A rotating shaft 8 is fixedly installed on the connecting folding plate 7, and the rotating shaft 8 is rotatably connected to the fixing block 9. When the antenna needs to be folded, by pushing the moving slide plate 56 upward, the moving slide plate 56 slides on the limiting rod 57 and squeezes the connecting spring 58, so that the moving slide plate 56 moves upward. During this process, the moving slide plate 56 drives the two limiting slide plates 54 to move away from each other through the hinged connecting plate 59, and then drives the two limiting slide plates 54 to move out of the two limiting jacks 510 respectively, thereby releasing the restriction on the second mounting base 4. The operation of unlocking the limiting mechanism 5 is simple and convenient. Only by pushing the moving slide plate 56 upward can the unlocking action be completed, which reduces the operation difficulty and improves the efficiency of antenna folding, providing convenience for users to quickly adjust the antenna form during actual use; after releasing the restriction on the second mounting base 4, the second mounting base 4 can be rotated, so that the rotating shaft 8 rotates on the first mounting base 3. When the antenna rod 2 on the second mounting base 4 rotates to the elastic clamping plates 63 below, the two elastic clamping plates 63 limit and fix the antenna rod 2. The design of the elastic clamping plates 63 can make full use of its own elastic deformation ability to tightly clamp the antenna rod 2, ensuring the stability of the folded antenna rod 2, avoiding damage to the antenna caused by shaking or other reasons in the folded state, effectively improving the service life and reliability of the antenna, and at the same time enabling the antenna to maintain a compact form after folding, which is convenient for storage and carrying.

[0023] As Figure 4As shown in the figure, the limiting mechanism 5 includes a limiting seat 53 fixedly installed on the first mounting seat 3 and a fixed support plate 55. A groove is provided in the middle of the limiting seat 53. The lower end of the fixed support plate 55 is fixedly connected with a limiting rod 57. A moving slide plate 56 is slidably connected to the limiting rod 57. Hinged connecting plates 59 are hinged at both ends of the moving slide plate 56. One end of the hinged connecting plate 59 away from the moving slide plate 56 is hinged with a limiting slide plate 54. The limiting slide plate 54 is slidably connected to the limiting seat 53. A connecting spring 58 is sleeved on the limiting rod 57. One end of the connecting spring 58 is fixedly connected with the fixed support plate 55, and the other end of the connecting spring 58 is fixedly connected with the moving slide plate 56. By pushing the moving slide plate 56 upward, the moving slide plate 56 slides on the limiting rod 57 and compresses the connecting spring 58. The moving slide plate 56 moves upward. Through the hinged connecting plate 59, the two limiting slide plates 54 are driven to move away from each other, and then the two limiting slide plates 54 are respectively moved out of the two limiting insertion holes 510, releasing the restriction on the fixed plate 52.

[0024] As Figure 4 shown, the limiting mechanism 5 further includes a connecting fixed block 51 fixedly installed on the second mounting seat 4. A fixed plate 52 is fixedly installed on the connecting fixed block 51. A limiting insertion hole 510 for the limiting slide plate 54 to extend into is provided on the fixed plate 52. The fixed plate 52 can be rotated into the groove.

[0025] As Figure 5 shown, the clamping assembly 6 includes a connecting block 61 fixedly installed on the antenna rod 2. Elastic clamping plates 63 are symmetrically arranged on the connecting block 61. A buffer pad 62 is fixedly connected to the connecting block 61. The two elastic clamping plates 63 are used to clamp and limit the folded antenna rod 2. By rotating the second mounting seat 4, when the antenna rod 2 on the second mounting seat 4 rotates to the lower elastic clamping plate 63, the two elastic clamping plates 63 limit and fix the antenna rod 2, ensuring the stability of the folded antenna rod 2.

[0026] The state of the antenna in the unfolded state is as Figure 1 shown. When the antenna needs to be folded, refer to Figure 2 , by pushing the moving slide plate 56 upward, the moving slide plate 56 slides on the limiting rod 57 and compresses the connecting spring 58. The moving slide plate 56 moves upward. Through the hinged connecting plate 59, the two limiting slide plates 54 are driven to move away from each other, and then the two limiting slide plates 54 are respectively moved out of the two limiting insertion holes 510, releasing the restriction on the fixed plate 52. At this time, by rotating the second mounting seat 4, when the rotation shaft 8 rotates on the first mounting seat 3 and the antenna rod 2 on the second mounting seat 4 rotates to the lower elastic clamping plate 63, the two elastic clamping plates 63 limit and fix the antenna rod 2, ensuring the stability of the folded antenna rod 2.
