Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Antenna rotating joints, including joint bases and joint cards that are movably connected. The joint seat and the joint card are provided with corresponding elastic arms and grooves; there are multiple grooves distributed on the circumference; the elastic arms are provided with ribs, and the ribs correspond to the shape of the grooves; When stationary, the convex ribs are stuck in the grooves, and when rotating, the convex ribs are on the protruding parts between the grooves. The groove is arranged on the joint seat, and the elastic arm is arranged on the joint card; or, the groove is arranged on the joint card, and the elastic arm is arranged on the joint seat. The plurality of grooves are evenly distributed on a circle, and the number corresponds to the number of elastic arms; there are one, two or three elastic arms, which are divide...

Abstract

The invention discloses an antenna revolute joint which comprises a joint support and a joint clamp which are movably connected with each other. Bodies on the joint support and the joint clamp are respectively a ferrule and a column inserted for matching; the matching surfaces of the ferrule and the column are respectively provided with a plurality of corresponding elastic arms and a plurality of grooves; the grooves are uniformly distributed on the ferrule or the periphery of the column; the number of the elastic arms is less than or equal to that of the grooves; moreover, the elastic arms are uniformly distributed on the ferrule or the periphery of the column; the top ends of the elastic arms are provided with parallel element rests of the ferrule or the periphery shaft of the column; the element rests correspond to the grooves in shapes; when being static, the element rests are clamped in the grooves; and when rotating, the elastic deformation of the elastic arms are used for leading the element rests between the extruding parts in the grooves and the grooves to carry out mutual alternating motion in different grooves.

Description

technical field [0001] The invention belongs to the technical field of communication electronic equipment structure, in particular, the satellite communication hand-held station antenna can be effectively combined with the main body of the device, so as to achieve a satellite communication hand-held station antenna rotation with small appearance, light weight, and fast and reliable use. joint structure. Background technique [0002] The satellite communication handheld station has been developed and improved in recent years. Its communication function is similar to that of a commonly used mobile phone, but the difference is that the handheld station must meet the conditions for field use due to its specific use environment and conditions: Waterproof, temperature, shockproof, anti-electromagnetic interference, etc., so the metal shell is generally used in the structural design, and the satellite communication antenna is installed separately from the main body of the communica...
