Description

Portable five-element array antenna mechanism Technical Field The invention relates to the technical field of radio communication navigation devices, in particular to a portable five-element array antenna mechanism. Background Portable five-element array antennas are used as important electronic reconnaissance and communication devices, and generally cover a wide frequency range. To optimize performance and portability, it is often structurally divided into two frequency band elements, a G1 band antenna (1 GHz-2 GHz) and a G2 band antenna (0.3 GHz-1 GHz). The two have obvious differences in physical structure that the G1 antenna has a compact structure, the diameter is not more than 300mm, the height is not more than 100mm, and the unfolding size of the G2 antenna is far larger than that of the G1 antenna due to longer working wavelength, the diameter can reach 1500-2000mm, and the height is 400-500 mm. This large size, while providing performance advantages, also presents serious challenges for its transportation, storage, and rapid deployment in the field, making foldable designs a necessary choice for such antenna structures. However, the existing portable antenna folding structure has the following disadvantages: The tool is strong in dependence, complex in operation and prone to losing parts, and the prior art mainly relies on conventional screws or hand-screwed screws not falling off to lock and fix parts. The conventional screw is required to be provided with a special tool (such as a screwdriver), so that the tool is inconvenient to carry in field operation, and the screw is easy to lose after being detached, so that the equipment cannot be assembled again. The hand screw avoids the need for tools, but the operation of screwing in and out is inefficient, and there is also a small part management problem. Secondly, the contradiction between the structural space and the operation convenience is outstanding, and when the scheme of screwing the screw by hand is adopted, a larger vacant area is reserved around the screw to ensure enough operation space for screwing by hand. This directly conflicts with the design objective of antennas, especially small-sized devices such as G1, for which compact size is sought. For the huge folding mechanism of the G2 antenna, the unfolding and storage time is greatly prolonged by the inefficient thread locking mode, and the requirement of quick deployment cannot be met. The existing technical scheme can not integrate folding action and locking or unlocking mechanism, and is in linkage design. The folding process is often separated from the locking process, resulting in a complicated process, which requires step-by-step operations by the user. More importantly, the locking force of the existing locking structure is fixed, the requirement of the different locking force caused by different application scenes, different size specifications and different weights of the G2 frequency band antenna cannot be flexibly adapted, and the universality and the compatibility are poor. Disclosure of Invention The invention aims to solve the technical problem of overcoming the defects of the prior art and providing the portable five-element array antenna mechanism which has a simple and compact structure and can realize the linkage of rapid unfolding or folding and folding locking processes without using tools. In order to solve the technical problems, the invention adopts the following technical scheme: the portable five-element array antenna mechanism comprises an oscillator arm installation seat for installing a G2 five-element array antenna and a five-element installation seat for installing a G1 five-element array antenna, wherein the top of the oscillator arm installation seat is connected with the five-element installation seat through a connecting part, the G2 five-element array antenna comprises a plurality of first folding locking components which are sequentially arranged on the periphery of the oscillator arm installation seat, each first folding locking component is hinged with a connecting rod for enabling the connecting rod to fold towards the five-element installation seat or outwards expand and lock during operation during storage, a second folding locking component is arranged at the outer end part of each connecting rod, and each second folding locking component is hinged with two oscillator arms for enabling the two oscillator arms to fold towards the connecting rod during storage or outwards expand and lock during operation. As a further improvement of the above technical scheme: The second folding locking assembly comprises wall boxes fixed at the end parts of the connecting rods, the upper end and the lower end of each wall box are respectively provided with a connecting seat, each connecting seat is rotatably connected with a rotating seat used for fixing the vibrator arm through a rotating shaft, each connecting seat is provided with a limiting groove, each rotat
