Description

Technical Field

[0001] This invention belongs to the field of antenna locking technology, specifically, it relates to an azimuth locking mechanism for a portable antenna. Background Technology

[0002] Microwave communication is an important means of communication in national communication networks. Microwave communication offers advantages such as large capacity, high quality, and the ability to transmit over long distances, making it widely applicable to various dedicated communication networks. Microwaves are a type of electromagnetic wave with a wavelength shorter than that of a typical television screen. Due to their strong penetrating power, they are not reflected by the ionosphere but are easily absorbed by the ground, thus they can only propagate in a straight line, with a propagation distance of only tens to over a hundred kilometers. Therefore, communications such as mobile phone communication rely on base stations.

[0003] In microwave communication, antennas are used to transmit information, and the adjustment of the antenna azimuth angle is crucial to the network quality of mobile communication. On the one hand, an accurate azimuth angle ensures that the actual coverage of the base station matches the expected coverage, guaranteeing the overall network operation quality. On the other hand, appropriate adjustments to the azimuth angle based on traffic volume or specific network conditions can better optimize the existing mobile communication network.

[0004] After manually adjusting the azimuth and elevation angles of a portable antenna to align with a target, a locking mechanism is required to maintain the working angle. Existing azimuth locking mechanisms mainly include the following types:

[0005] 1. Locking is achieved through mechanical self-locking of the transmission mechanism; for example, azimuth transmission uses a worm gear mechanism, which utilizes the self-locking principle of the worm gear. This type of structure is used in an antenna azimuth angle rotation device disclosed in application number 2011202038148.0. Another method is to use a trapezoidal screw and nut mechanism, which utilizes the self-locking principle of the trapezoidal screw and nut. The disadvantage of this type of mechanism is that the transmission mechanism is complex, large in size, and heavy.

[0006] 2. Locking is achieved using a fixed frictional torque; for example, an O-ring is placed between the azimuth moving shaft and the fixed shaft. The O-ring provides a fixed frictional torque, and the azimuth working angle is locked when the external load does not exceed this frictional torque. The disadvantages of this type of locking mechanism are: poor reliability, it will fail under large loads or impact vibrations; inconvenient operation, because the frictional torque is always present, and this frictional torque must be overcome when rotating the azimuth structure. Furthermore, it generally suffers from complex structure, large size, heavy weight, or low reliability. Summary of the Invention

[0007] The purpose of this invention is to provide an azimuth locking mechanism for a portable antenna, which mainly solves the problems of existing locking mechanisms being complex in structure, large in size, heavy in weight, and low in reliability.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0009] An azimuth locking mechanism for a portable antenna includes a locking housing fixed to the back of an azimuth movable plate of the portable antenna by screws, a baffle fixed to the locking housing by screws, an elastic pad disposed inside the locking housing and supported by the baffle, a locking tongue abutting against the elastic pad and extending from one end of the locking housing, an insertion hole formed on the azimuth movable plate and facing the locking tongue, and a locking piece for being movably inserted into the insertion hole and pressing the locking tongue after insertion; wherein the gap between the locking tongue and the azimuth stationary plate of the portable antenna is less than the thickness of the locking piece.

[0010] Furthermore, in this invention, the front end of the locking housing is provided with an insertion notch, and the portion of the locking tongue that protrudes from the locking housing is located within the insertion notch.

[0011] Furthermore, in this invention, the width of the insertion notch is the same as the width of the locking piece.

[0012] Furthermore, in this invention, the baffle is provided with two uprights, and the elastic gasket is two annular gaskets, which are sleeved on the uprights.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The locking mechanism of this invention is installed on the azimuth moving plate of a portable antenna. A gap exists between the locking tongue of the locking mechanism and the azimuth stationary plate of the portable antenna. This gap is slightly smaller than the thickness of the locking plate. When the locking plate is inserted between the locking tongue and the azimuth stationary plate, the insertion of the locking plate causes a lateral displacement of the locking tongue. This displacement causes pressure to be applied to the elastic washer. Under this pressure, the locking plate and the azimuth stationary plate are pressed together, thereby achieving locking between the azimuth moving plate and the azimuth stationary plate. Compared with existing mechanisms, this mechanism is characterized by its small size, light weight, and simple operation. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0021] Example

[0022] This invention discloses an azimuth locking mechanism for a portable antenna, which is applied to a manually operated portable antenna structure, such as... Figure 3 As shown, the azimuth structure mainly consists of a stationary azimuth disk and a moving azimuth disk, wherein the stationary azimuth disk is fixed and the moving azimuth disk rotates in a circular motion around the center of rotation of the stationary disk.

[0023] like Figure 1 , 2 As shown, the locking mechanism of the present invention is fixed on the azimuth disk and includes a locking housing 1 fixed to the back of the azimuth disk of the portable antenna by screws, a baffle 2 fixed to the locking housing 1 by screws, an elastic pad 3 disposed inside the locking housing 1 and supported by the baffle 2, a locking tongue 4 abutting against the elastic pad 3 and protruding from one end of the locking housing 1, an insertion hole 5 opened on the azimuth disk and facing the locking tongue 4, and a locking piece 6 for being movably inserted into the insertion hole 5 and pressing the locking tongue 4 after insertion; wherein, the gap between the locking tongue 4 and the azimuth disk of the portable antenna facing it is less than the thickness of the locking piece 6.

[0024] In this embodiment, the locking housing 1 has an insertion notch 7 at its front end, and the portion of the locking tongue protruding from the locking housing 1 is located within the insertion notch 7. Furthermore, the width of the insertion notch 7 is the same as the width of the locking piece 6. After the locking piece is inserted into the insertion hole 5 on the directional moving plate, it fits precisely into the insertion notch 7.

[0025] In this embodiment, two pillars 8 are provided inside the baffle 2, and the elastic gasket 3 consists of two annular gaskets that are sleeved on the pillars 8. These elastic gaskets feature "small deformation and large elasticity," facilitating the extension, retraction, and repositioning of the locking tongue 4, thereby achieving the locking of the directional locking mechanism.

[0026] Specifically, the locking mechanism is mounted on the azimuth moving plate and rotates with it. There is a gap m between the locking tongue and the azimuth stationary plate, which is slightly smaller than the thickness d of the locking plate. When the locking plate is pulled out, the locking mechanism is not in contact with the azimuth stationary plate, and the azimuth is in motion. When the locking plate is inserted between the locking tongue and the azimuth stationary plate, because the gap m is smaller than d, the insertion of the locking plate causes the locking tongue to have a lateral displacement s. This displacement s causes the elastic washer to generate pressure F. n ; Under pressure F n Under these conditions, the locking plate and the locating plate are pressed together, the coefficient of friction between the locking plate and the locating plate is f, and the locking force is F = F n ·f, the radius r of the azimuth stationary locking surface, generates a locking torque M = F n ·f·r, this torque achieves directional locking.

[0027] Through the above design, the locking mechanism of the present invention has the characteristics of small size, light weight and simple operation.

[0028] The above embodiments are merely one of the preferred embodiments of the present invention and should not be used to limit the scope of protection of the present invention. Any modifications or refinements made to the main design concept and spirit of the present invention that are not of substantial significance, but solve the same technical problem as the present invention, should be included within the scope of protection of the present invention.
