Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna adapter technology, and in particular to a durable antenna adapter. Background Technology
[0002] Antenna adapters (especially rotary adapters) are key components in modern wireless communication systems, widely used in satellite communications, radar systems, mobile base stations, test and measurement equipment, IoT terminals, and various other applications requiring antenna pointing adjustment or where space is limited. Their core function is to allow relative rotation between the antenna and the feed line or between equipment ports while maintaining continuous and stable RF signal transmission, enabling flexible antenna pointing adjustment or equipment layout.
[0003] A typical rotary antenna adapter usually consists of two main parts: a rotating shaft (usually connected to the antenna or movable end) and a rotating base (usually fixed to the device or fixed end). Rotary antenna adapters are an indispensable key component in modern wireless communication systems such as satellite communications, radar, mobile base stations, test equipment, and drones.
[0004] In previous antenna adapter designs, the connection structure between the rotating base and the rotating shaft had significant flaws. On the one hand, the connection was not stable enough. Conventional connection methods relied solely on simple sockets or threaded connections. In actual use scenarios, antenna adapters are frequently subjected to vibration, external pulling forces, and long-term repeated rotation, which can cause the connection between the rotating base and the rotating shaft to gradually loosen, leading to unstable signal transmission or even interruption. On the other hand, traditional designs were extremely weak in their mechanisms to prevent the two from separating. When subjected to large axial tensile forces, the rotating shaft could easily detach from the rotating base, not only damaging the antenna adapter but also seriously affecting the normal operation of communication equipment, greatly limiting its application in complex working conditions. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing a durable antenna adapter that improves connection stability and anti-separation capability through optimized snap-fit structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A durable antenna adapter includes a rotating base and a rotating shaft. The rotating base and the rotating shaft are rotatably connected. The rotating shaft is provided with a deformable fastener. The rotating base is provided with a locking part adapted to the fastener. The fastener forms a locking engagement with the locking part through its own deformation, thereby restricting the separation of the rotating shaft and the rotating base and allowing the two to rotate relative to each other.
[0007] Preferably, the rotating base is provided with a connecting groove, the rotating shaft is provided with a connecting end adapted to the connecting groove, the connecting end can be rotatably inserted into the connecting groove, and the engaging part is a snap-fit groove provided on the inner wall of the connecting groove. Rotation is achieved by inserting the connecting end into the connecting groove, and the snap-fit groove provides a mating position for the fastener, thereby improving the reliability and assembly convenience of the overall structure.
[0008] Preferably, the fastener is an open annular structure that surrounds the rotating shaft. The rotating shaft has a mounting groove, and the fastener is disposed in the mounting groove. The annular structure achieves engagement with the engaging part through its own elastic deformation. The open annular structure facilitates elastic deformation, and the mounting groove provides positioning and constraint for the fastener.
[0009] Preferably, the rotating shaft is provided with a locking end, and the locking end is provided with a guide surface three for guiding the installation of the locking device. During the installation of the locking device, the guide surface three guides the locking device to deform, so that it can smoothly pass through the locking end and enter the mounting slot, reducing the installation difficulty of the locking device and making it easier to install the locking device onto the rotating shaft.
[0010] Preferably, the locking end is provided with an inverted inclined surface, which is inclined outward towards the locking component. When the rotating shaft is pulled outward relative to the rotating base, the inverted inclined surface can directly apply a radial expansion force to the locking component, forcing the locking component to fit more tightly with the locking groove of the rotating base. This structurally ensures the directionality and effectiveness of the anti-separation function and avoids force transmission failure caused by incorrect tilt direction.
[0011] Preferably, the effective working diameter of the inclined surface is not less than the diameter of the inner sidewall of the annular fastener, and the inclined surface does not cross the center line of the cross-section of the annular fastener, ensuring that there is a radial overlap area between the inclined surface and the inner sidewall of the fastener, avoiding the inclined surface from sliding directly out of the inner ring of the fastener, and ensuring that the inclined surface can reliably contact the fastener when it is pulled out.
[0012] Preferably, the connecting end of the rotating shaft is provided with a second guide surface for guiding the connecting end into the connecting groove, and the rotating base is provided with a first guide surface for guiding the deformation of the fastener. The second guide surface guides the connecting end to be smoothly inserted into the connecting groove, and the first guide surface guides the fastener to deform over the relevant parts during the insertion process, which reduces the assembly difficulty of the rotating shaft and the rotating base, reduces the wear of parts during the assembly process, and improves the assembly efficiency.
[0013] Preferably, a gap is provided between the fastener and the mounting slot. This gap provides space for the deformation of the fastener, preventing interference between the fastener and the inner wall of the mounting slot during deformation, and ensuring the effective fit between the fastener and the locking part.
[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model achieves a stable connection between the rotating base and the rotating shaft through the elastic engagement of the deformable fastener and the locking part, effectively preventing separation between the two. The inclined surface of the locking end is tilted towards the outside of the fastener, and the effective working diameter is not less than the inner wall diameter of the fastener, ensuring that an expansion force can be reliably applied when pulled by external force, enhancing the anti-separation effect. The equipment with multiple guide surfaces can reduce assembly difficulty and avoid damage to components. The gap between the fastener and the mounting groove is a deformation reserve space to reduce wear. Overall, it improves the connection stability, resistance to external forces and service life of the adapter, and is suitable for complex working conditions such as vibration and frequent operation.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example
[0022] Please see Figure 1-4 A durable antenna adapter includes a rotating base 1 and a rotating shaft 2. The rotating base 1 and the rotating shaft 2 are rotatably connected. The rotating shaft 2 is provided with a deformable fastener 3. The rotating base 1 is provided with a locking part adapted to the fastener 3. The fastener 3 forms a locking engagement with the locking part through its own deformation, so as to restrict the separation of the rotating shaft 2 and the rotating base 1 and allow the two to rotate relative to each other.
[0023] The rotating base 1 is provided with a connecting groove 11, and the rotating shaft 2 is provided with a connecting end 21 that is adapted to the connecting groove 11. The connecting end 21 can be rotatably inserted into the connecting groove 11. The engaging part is a snap-fit groove 12 provided on the inner wall of the connecting groove 11. Rotation is achieved by inserting the connecting end 21 into the connecting groove 11. At the same time, the snap-fit groove 12 provides a mating position for the fastener 3, which improves the reliability of the overall structure and the ease of assembly.
[0024] The fastener 3 is an open annular structure that surrounds the rotating shaft 2. The rotating shaft 2 has a mounting groove 23, and the fastener 3 is located in the mounting groove 23. The annular structure achieves engagement with the engaging part through its own elastic deformation. The open annular structure facilitates elastic deformation. The mounting groove 23 plays a role in positioning and constraining the fastener 3. There is a gap between the fastener 3 and the mounting groove 23. This gap provides space for the deformation of the fastener 3, avoids interference between the fastener 3 and the inner wall of the mounting groove 23 during deformation, and ensures the engagement effect between the fastener and the engaging part.
[0025] The rotating shaft 2 is provided with a locking end 24, and the locking end 24 is provided with a guide surface 3 242 for guiding the installation of the locking device 3. During the installation of the locking device 3, the guide surface 3 242 guides the locking device 3 to deform, so that it can smoothly pass through the locking end 24 and enter the mounting slot 23, reducing the installation difficulty of the locking device 3 and making it easier to install the locking device 3 onto the rotating shaft 2.
[0026] The locking end 24 is provided with an inverted inclined surface 241, which is inclined outward towards the locking fastener 3. When the rotating shaft 2 is pulled outward relative to the rotating base 1, the inverted inclined surface 241 can directly apply a radial expansion force to the locking fastener 3, forcing the locking fastener 3 to fit more tightly with the locking groove 12 of the rotating base 1. Structurally, this ensures the directionality and effectiveness of the anti-separation function and avoids the failure of force transmission due to incorrect tilt direction.
[0027] The effective working diameter of the inclined surface 241 is not less than the diameter of the inner wall of the annular fastener 3. The inclined surface does not cross the center line of the cross section of the annular fastener 3, ensuring that there is a radial overlap area between the inclined surface 241 and the inner wall of the fastener 3. This prevents the inclined surface 241 from sliding directly out of the inner ring of the fastener 3, ensuring that the inclined surface 241 can reliably contact the fastener 3 when pulled out. When the fastener 3 is installed in the mounting slot 23, the inclined surface of the inclined surface 241 is opposite to the inner wall of the fastener 3, and there is an overlap area between the two in the radial direction. When the rotating shaft 2 is pulled outward relative to the rotating base 1, the inclined surface 241 moves upward with the mounting end 24, accurately contacting the inner wall of the fastener 3, rather than passing directly through the inner ring of the fastener 3. This reliably applies an outward expansion force to the fastener 3, ensuring its tight engagement with the mounting slot 12 and preventing the anti-separation function from failing due to insufficient size of the inclined surface 241.
[0028] The connecting end 21 of the rotating shaft 2 is provided with a guide surface 22 for guiding the connecting end 21 into the connecting groove 11. The rotating base 1 is provided with a guide surface 13 for guiding the deformation of the fastener 3. The guide surface 22 guides the connecting end 21 to smoothly insert into the connecting groove 11. The guide surface 13 guides the fastener 3 to deform and pass over the relevant parts during the insertion process, which reduces the assembly difficulty of the rotating shaft 2 and the rotating base 1, reduces the wear of parts during the assembly process, and improves the assembly efficiency.
[0029] During assembly, the fastener 3 is installed into the mounting slot 23 of the rotating shaft 2. During the installation process, the fastener 3 contacts the guide surface 242 of the mounting end 24. The guide surface 242 guides the fastener 3 to deform, so that the fastener 3 can smoothly pass over the mounting end 24 and complete the installation of the fastener 3.
[0030] Then, the connecting end 21 of the rotating shaft 2 is aligned with the connecting groove 11 of the rotating base 1. During the process of inserting the connecting end 21 into the connecting groove 11, the guide surface 22 on the connecting end 21 guides the connecting end 21 to be inserted smoothly. At the same time, the guide surface 13 on the rotating base 1 contacts the fastener 3, guiding the fastener 3 to deform and pass over the guide surface 13. When the fastener 3 reaches the position of the locking groove 12 on the inner wall of the connecting groove 11, the fastener 3 deforms under its own elasticity and engages with the locking groove 12 to realize the connection between the rotating shaft 2 and the rotating base 1 and prevent the two from separating. When the rotating shaft 2 is pulled outward relative to the rotating base 1, the locking end 24 moves upward accordingly. The chamfered surface 241 on the locking end 24 contacts the fastener 3 and applies a radially outward expansion force to the fastener 3, so that the fastener 3 remains engaged with the locking groove 12, which can effectively prevent the rotating shaft 2 from separating from the rotating base 1, so that the rotating shaft 2 and the rotating base 1 can be stably rotated.
[0031] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
