Description

Technical Field

[0001] This utility model relates to the field of antenna adapter technology, and in particular to a rotating structure for an 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). Regarding the smoothness of shaft rotation, most adapter rotating structures lack proper stress relief and buffering designs, leading to jamming at the connection end during rotation due to stress concentration. Taking handheld walkie-talkie antenna adapters as an example, the jamming problem is particularly noticeable when users frequently adjust the antenna angle. This not only reduces the user experience but also shortens the adapter's lifespan due to excessive localized wear. Furthermore, in traditional rotating structures, improper gap treatment between the connection end and the rotating base's connecting groove results in either excessively large gaps leading to loose connections and affecting signal transmission stability, or excessively small gaps exacerbating friction between components, further hindering smooth shaft rotation. In addition, existing rotating structures struggle to balance smooth rotation and connection stability under various operating conditions, failing to meet the diverse usage requirements of communication equipment. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an antenna adapter rotation structure that achieves smooth rotation through deformation compensation and elastic adjustment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An antenna adapter rotating structure includes a rotating base and a rotating shaft. The rotating base is provided with a connecting groove, and the rotating shaft is provided with a connecting end adapted to the connecting groove. The connecting end is rotatably disposed in the connecting groove. The mating part between the connecting end and the connecting groove is provided with an elastic adjustment structure for improving the smoothness of rotation. The elastic adjustment structure can compensate for the mating gap and adapt to relative rotation through its own deformation.

[0006] Preferably, the elastic adjustment structure is a deformation structure located at the connection end. The deformation structure includes a hollow groove inside the connection end and a deformation groove communicating with the hollow groove. The deformation groove enables the connection end to have deformation adaptation function. The deformation groove enables the connection end to have deformation adaptation force, so that it can adapt to stress changes when the shaft rotates, ensuring that the shaft is stable and smooth during rotation and improving rotation flexibility.

[0007] Preferably, the deformation groove is formed by connecting a horizontal groove segment and a vertical groove segment, forming a T-shape. Through this T-shaped deformation groove design, when the connecting end is subjected to rotational stress or assembly force, the horizontal and vertical groove segments work together to provide deformation space, enabling the connecting end to have a more reasonable elastic deformation capability. By setting the hollow groove and the deformation groove, the connecting end is endowed with elastic deformation capability, so that it can adapt to stress changes when the shaft rotates, ensuring that the shaft is stable and smooth during rotation and improving rotational flexibility.

[0008] Preferably, the elastic adjustment structure is an elastic compensation component disposed between the connecting end and the connecting groove. The elastic compensation component has parts that respectively abut against the connecting end and the connecting groove. Through its specific abutting parts, effective compensation and interference fit of the gap can be achieved.

[0009] Preferably, the elastic compensator includes an upper end, a lower end, and an abutting portion located between the two. The abutting portion is curved in an arc shape toward the connecting end, and the abutting portion is provided with multiple slots. Through the multiple slots, the material deformation is smooth during the bending process of the elastic compensator, which can reduce the additional stress caused by forced bending. The slots can help adjust the strain distribution during bending. The abutting portion forms an arc shape that bends toward the connecting end. This arc-shaped structure gives the abutting portion good elastic deformation capability. When subjected to external force, it can produce elastic deformation. When the elasticity is within the gap between the connecting end and the connecting groove, the upper end and the lower end abut against the connecting groove, and the abutting portion abuts against the connecting end.

[0010] Preferably, the elastic compensation member is an elastic ring structure with an opening that is not connected end to end, and the open elastic ring structure gives it better deformation force.

[0011] Preferably, a gap is provided between the connecting end and the connecting groove, and the elastic compensation member is used to compensate for the gap and form an interference fit. The elastic compensation member is used to compensate for the gap between the connecting end and the connecting groove to form an interference fit, which ensures a stable connection without affecting rotation.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention improves the smoothness of adapter rotation through an elastic adjustment structure. It can be given deformation adaptability through the hollow groove and deformation groove at the connection end, thereby absorbing rotational stress. Alternatively, it can compensate for gaps through an elastic compensation component. The elastic compensation component compensates for gaps through an arc-shaped contact part and a slot, forming an interference fit. Both solutions can balance connection stability and rotational flexibility, reduce jamming and wear, and solve the problem of improper gap handling in traditional structures. This can effectively improve the rotation feel and service life, and adapt to the rotational performance requirements of various communication devices. Attached Figure Description

The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0019] 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.

[0020] Example 1: Please see Figures 1-4 An antenna adapter rotating structure includes a rotating base 1 and a rotating shaft 2. The rotating base 1 is provided with a connecting groove 11, and the rotating shaft 2 is provided with a connecting end 21 adapted to the connecting groove 11. The connecting end 21 is rotatably disposed in the connecting groove 11. The mating part of the connecting end 21 and the connecting groove 11 is provided with an elastic adjustment structure for improving the smoothness of rotation. The elastic adjustment structure can compensate for the mating gap and adapt to relative rotation through its own deformation.

[0021] The elastic adjustment structure is a deformation structure located at the connecting end 21. The deformation structure includes a hollow groove 22 inside the connecting end 21 and a deformation groove 23 communicating with the hollow groove 22. The deformation groove 23 enables the connecting end 21 to have deformation adaptation function. Through the deformation groove 23, the connecting end 21 has deformation adaptation force, so that it can adapt to stress changes when the rotating shaft 2 rotates, ensuring that the rotating shaft 2 is stable and smooth during rotation and improving rotation flexibility.

[0022] The deformation groove 23 is formed by connecting the transverse groove section 231 and the vertical groove section 232, forming a T-shape. Through this T-shaped deformation groove 23 design, when the connecting end 21 is subjected to rotational stress or assembly force, the transverse and vertical groove sections 232 work together to provide deformation space, enabling the connecting end 21 to have a more reasonable elastic deformation capability. Through the setting of the hollow groove 22 and the deformation groove 23, the connecting end 21 is endowed with elastic deformation capability, so that it can adapt to stress changes when the rotating shaft 2 rotates, ensuring that the rotating shaft 2 is stable and smooth during rotation, and improving rotational flexibility.

[0023] During production, the transverse groove 231 is opened along the radial direction of the connecting end 21, perpendicular to the axis of the rotating shaft 2. The groove penetrates the outer wall of the connecting end 21 and communicates with the hollow groove 22 inside. The vertical groove 232 is opened along the axial direction of the connecting end 21, parallel to the axis of the rotating shaft 2. One end of the vertical groove 232 is connected to the middle position of the transverse groove 231, and the other end extends towards the end of the connecting end 21 and penetrates the end face of the connecting end 21. The transverse groove 231 and the vertical groove 232 together form a deformation space connected with the hollow groove 22, which rotates and engages the rotating shaft 2 with the rotating base 1. When the rotating shaft 2 is rotated, since the connecting end 21 is provided with the hollow groove 22 and the deformation groove 23, the connecting end 21 has elastic deformation capability. This allows the connecting end 21 to adapt to the stress changes caused by the rotation through elastic deformation during the rotation of the rotating shaft 2, ensuring that the rotating shaft 2 rotates stably and smoothly relative to the rotating base 1.

[0024] Example 2: Please see Figures 5-7 The elastic adjustment structure is an elastic compensation member 3 located between the connecting end 21 and the connecting groove 11. The elastic compensation member 3 has portions that abut against the connecting end 21 and the connecting groove 11 respectively. Through its specific abutting portion 32, it achieves effective compensation and interference fit for the gap. The elastic compensation member 3 includes an upper end 31, a lower end 33, and an abutting portion 32 located between the two. The abutting portion 32 is curved in an arc shape towards the connecting end 21, and has multiple slots. Through the multiple slots, the elastic compensation is achieved. During the bending process, the groove allows the material to deform smoothly, reducing the additional stress caused by forced bending. The groove can help adjust the strain distribution during bending. The contact part 32 forms an arc shape that bends towards the connecting end 21. This arc structure gives the contact part 32 good elastic deformation capability. When subjected to external force, it can produce elastic deformation. When the elasticity is within the gap between the connecting end 21 and the connecting groove 11, the upper end 31 and the lower end 33 abut against the connecting groove 11, and the contact part 32 abuts against the connecting end 21.

[0025] Its elastic compensator 3 is an open elastic ring structure with no connection at the ends. The open elastic ring structure gives it good deformation force. The opening allows the elastic compensator 3 to shrink radially under external pressure, making it easier to insert into the connecting groove 11, reducing assembly difficulty and avoiding damage to components caused by forced installation. It is especially suitable for scenarios where the space of the connecting groove 11 is narrow. The open structure also gives the elastic compensator 3 a larger elastic deformation space, which can ensure that the contact part 32 and the connecting end 21, and the upper and lower ends 33 and the connecting groove 11 are tightly fitted. This ensures the stability of the interference fit and allows for flexible deformation during rotation to adapt to the rotation and reduce jamming.

[0026] A gap is provided between the connecting end 21 and the connecting groove 11. The elastic compensation member 3 is used to compensate for the gap and form an interference fit. The elastic compensation member 3 is used to compensate for the gap between the connecting end 21 and the connecting groove 11 to form an interference fit, which ensures a stable connection without affecting the rotation.

[0027] Before rotatably connecting the connecting end 21 of the rotating shaft 2 to the rotating base 1, the elastic compensating member 3 is first placed into the connecting groove 11 on the rotating base 1. Since the elastic compensating member 3 is an open elastic ring structure with its ends not connected, its two sides can be slightly squeezed along the opening direction by external force before assembly. The diameter of the ring structure is temporarily reduced by utilizing the deformation allowance of the opening, making it easier to be placed into the preset position in the connecting groove 11. After the elastic compensating member 3 is placed in, the applied external force is released. The compensating member returns to its original position due to its own elasticity, and its diameter slightly expands, so that the upper end 31 and the lower end 33 tightly abut against the connecting groove 11. The inner wall is then inserted, and the connecting end 21 on the rotating shaft 2 is inserted into the rotating base 1 for rotational connection. After the connecting end 21 is inserted, the arc-shaped contact part 32 can fit against the outer wall of the connecting end 21 to form an interference fit. When the rotating shaft 2 is rotated, the elastic sheet of the elastic compensation part 3 has good elasticity. The upper end 31 and the lower end 33 can move slightly adaptably in the connecting groove 11. The contact part 32 deforms flexibly with the rotation of the connecting end 21. While ensuring a stable fit between the connecting end 21 and the connecting groove 11, the rotating shaft 2 is allowed to rotate smoothly relative to the rotating base 1, so as to realize the flexible adjustment of the antenna angle.

[0028] 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.
