Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to a connection device for a 5G base station AAU. Background Technology

[0002] With the rapid development of fifth-generation mobile communication technology (5G), the construction of 5G base stations is unfolding on a large scale globally. Active antenna units (AAU) are a crucial component of 5G base stations. Compared to AAUs in fourth-generation (4G) base stations, 5G AAUs are significantly heavier, posing new challenges to 5G base station construction. Particularly during the installation and subsequent angle adjustment of the AAUs, their large size and weight make traditional installation and adjustment methods extremely difficult and time-consuming. Current technologies often require significant manpower for precise angle adjustment of installed heavy AAUs, involving complex operations and sometimes requiring partial disassembly or reinstallation. This not only increases the labor intensity and safety risks for construction workers but also severely impacts base station construction efficiency and subsequent maintenance.

[0003] Therefore, how to conveniently and efficiently achieve precise angle adjustment of heavy-duty 5G base station AAU equipment after installation is a pressing technical problem that needs to be solved in the current construction of 5G base stations. Existing technologies urgently need improvement to address this issue. Utility Model Content

The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] With the continuous evolution of communication technology, the deployment of 5G networks has placed new demands on the installation of base station equipment. Compared to 4G base stations, the weight of AAU equipment in 5G base stations has increased significantly, posing a significant challenge to traditional installation and angle adjustment methods. In actual engineering projects, accurately installing heavy AAU equipment onto the bracket and making fine angle adjustments often requires a large amount of manpower and resources, and the operation process is complex and inefficient, especially in high-altitude working environments, where safety risks also increase. In existing technologies, adjusting the angle of installed heavy AAU equipment usually requires the cooperation of multiple people, and may even require the use of lifting equipment or partial disassembly of the installation structure, which seriously restricts the construction speed and maintenance efficiency of 5G base stations. To overcome these limitations in existing technologies, this utility model proposes a novel connecting device for 5G base station AAU. This device, through its unique design, allows for convenient and precise angle adjustment of the AAU equipment after installation. Specifically, the connection device of this utility model includes an upper connection component 30 and a lower connection component 40 for connecting the base station 20 to the bracket 10. The lower connection component 40 is provided with an adjustment component 50, which realizes convenient adjustment of the angle of the base station 20 through the cooperation of the adjustment bolt 511, the adjuster 52 and the connector 53.

[0024] To better understand the technical solution of this utility model, some key terms and implementation environments involved are explained below. The "base station" referred to in this utility model typically refers to the AAU equipment in a 5G base station, which is relatively heavy and needs to be stably mounted on a bracket. This "bracket" can be a communication tower, pole, or other similar support structure. The connecting device of this utility model is used to reliably fix the base station 20 to the bracket 10 and allows for angle adjustment after installation.

[0025] Specifically, the connection device of this utility model includes an upper connection component 30 and a lower connection component 40, which are used to connect the upper and lower parts of the base station 20, respectively, and are connected to the bracket 10. See also Figure 1 and Figure 2 The upper connecting component 30 and the lower connecting component 40 are fixed on the vertical bracket 10 by clamping and support the base station 20.

[0026] Further, see Figure 3The upper connecting assembly 30 includes a first fixing clip for holding the bracket 10, an upper connecting member 32 connected to the first fixing clip, and a first mounting block 33 hinged to the upper connecting member 32. The first mounting block 33 is used to connect the base station 20. As one possible implementation, the first fixing clip can be composed of a first sub-clamp 311 and a first female clamp 312 connected by bolts, thereby forming an adjustable-size clamping structure to accommodate brackets 10 of different diameters. One end of the upper connecting member 32 can be fixedly connected to the first female clamp 312 of the first fixing clip, and the two are integrally formed. The other end of the upper connecting member 32 is hinged to the first mounting block 33, and this hinge structure allows the upper connecting member 32 to rotate within a certain range relative to the first mounting block 33. The first mounting block 33 can be fixed to the back of the base station 20 by bolts or other means.

[0027] Further, see Figure 4 The lower connecting assembly 40 includes a second fixing clip for holding the bracket 10, a lower connecting member 42 connected to the second fixing clip, and a second mounting block 43 connected to the lower connecting member 42 via an adjusting assembly 50. The second mounting block 43 is used to connect the base station 20. As one possible implementation, the second fixing clip can be composed of a second sub-clamp 411 and a second female clamp 412 connected by bolts, and its function is similar to that of the first fixing clip, used to hold the lower part of the bracket 10. One end of the lower connecting member 42 can be fixedly connected to the second female clamp 412 of the second fixing clip, and the two are integrally formed. The other end of the lower connecting member 42 is connected to the second mounting block 43 via the adjusting assembly 50. The second mounting block 43 can be fixed to the back of the base station 20 by bolts or other means.

[0028] The adjustment component 50 is the key part for achieving angle adjustment. See also Figure 4 and Figure 5 The adjustment assembly 50 includes an adjusting bolt 511 vertically threaded into the lower connector 42, an adjuster 52, and a connector 53 hinged to the adjuster 52 and the second mounting block 43. The adjusting bolt 511 is vertically positioned and passes through a threaded hole on the lower connector 42 via a threaded connection. The adjuster 52 is connected to the adjusting bolt 511; specifically, the bottom of the adjuster 52 has a pre-set connecting tube 521 that rotatably engages with the adjusting bolt 511. The connecting tube 521 can be sleeved on the top of the adjusting bolt 511, allowing the adjusting bolt 511 to rotate within it. The connector 53 is plate-shaped, with one end hinged to the adjuster 52 and the other end hinged to the second mounting block 43. By rotating the adjusting bolt 511, the adjuster 52 and the connector 53 can be driven to move, thereby adjusting the angle of the base station 20 relative to the bracket 10.

[0029] Compared to existing technologies that require complex operations and multi-person collaboration to adjust the angle of heavy-duty AAU equipment, the connecting device of this invention provides a more convenient and efficient solution. Existing technologies typically rely on loosening fixing bolts and then using external force to push or pull the equipment to adjust the angle. This method is not only laborious and difficult to control precisely, but also poses safety hazards when the equipment is heavy. This invention, however, transforms angle adjustment into a simple bolt rotation operation through the adjustment component 50 integrated into the lower connecting assembly. This design allows for angle adjustment by a single person, with a smooth and controllable adjustment process, enabling more precise angle positioning. Therefore, this invention surpasses existing technologies in terms of ease of operation, adjustment accuracy, and safety.

[0030] The working principle of this utility model is as follows: First, the upper connecting component 30 and the lower connecting component 40 are fixed at the upper and lower ends of the bracket 10, respectively, and the fixing clamps are tightened by tightening bolts. Then, the base station 20 is connected to the upper connecting component 32 and the lower connecting component 42 through the first mounting block 33 and the second mounting block 43, respectively. At this time, the base station 20 is stably installed on the bracket 10. If it is necessary to adjust the pitch angle of the base station 20, simply rotate the adjusting bolt 511 in the adjusting component 50. When the adjusting bolt 511 is rotated, due to its threaded engagement with the lower connecting component 42, the adjusting bolt 511 will move upward or downward in the vertical direction. The vertical movement of the adjusting bolt 511 is driven by the rotational engagement of its top end with the connecting tube 521 at the bottom of the adjuster 52, which in turn drives the adjuster 52 to move in the vertical direction. The adjuster 52 is hinged to the connecting component 53, and the other end of the connecting component 53 is hinged to the second mounting block 43 fixed on the base station 20. Therefore, the vertical movement of the adjuster 52 drives the connector 53 to rotate around its hinge point with the second mounting block 43, thereby pushing or pulling the lower part of the base station 20 closer to or further away from the bracket 10, thus changing the pitch angle of the base station 20. For example, when the adjusting bolt 511 moves upward, the adjuster 52 moves upward, causing the connector 53 to swing upward, making the lower part of the base station 20 move away from the bracket 10, and the base station 20 tilts upward; conversely, when the adjusting bolt 511 moves downward, the adjuster 52 moves downward, causing the connector 53 to swing downward, making the lower part of the base station 20 closer to the bracket 10. During this process, the hinge structure between the upper connector 32 of the upper connecting assembly 30 and the first mounting block 33 allows the base station 20 to rotate around the upper connecting assembly 30. In this way, the operator can conveniently and accurately adjust the optimal angle of the base station 20 to obtain the best communication coverage effect. In this technical solution, the fixing clamps of the upper connecting component 30 and the lower connecting component 40 are responsible for firmly fixing the device on the bracket 10 and bearing the weight of the device; the upper connecting member 32 and the lower connecting member 42 serve as bridges connecting the fixing clamp and the mounting block; the first mounting block 33 and the second mounting block 43 are responsible for connecting the device to the base station 20; the adjustment component 50 is the core mechanism for realizing angle adjustment, wherein the adjusting bolt 511 provides driving force, and the adjuster 52 and the connector 53 convert the linear motion of the adjusting bolt 511 into the rotational motion of the base station 20.

[0031] See Figure 1 and Figure 3In one specific embodiment of this utility model, the first fixing clip in the upper connecting assembly 30 is configured to consist of a first sub-clamp 311 and a first female clamp 312 connected by bolts. This structure allows the first fixing clip to adjust the size of its clamping opening by tightening or loosening the bolts, thereby accommodating brackets 10 of different diameters. The upper connecting member 32 is configured to be fixedly connected at one end to the first female clamp 312 of the first fixing clip, for example, by welding, riveting, or bolting, or the upper connecting member 32 and the first female clamp 312 are integrally formed. In this embodiment, the two are fixedly connected by integral forming. The other end of the upper connecting member 32 is hingedly connected to the first mounting block 33. This hinged connection is achieved by a pin, allowing the upper connecting member 32 to rotate freely relative to the first mounting block 33 within a certain angle range.

[0032] The first fixing clamp uses a combination of a first female clamp 311 and a first female clamp 312 connected by bolts. This is a common and reliable clamping structure. Its main technical feature is that it achieves a stable fixation of the bracket 10 through adjustable clamping force and is compatible with brackets of different specifications. The fixed connection between the upper connecting member 32 and the first female clamp 312 of the first fixing clamp ensures a rigid connection between the two, allowing the clamping force to be effectively transmitted. The hinged connection between the upper connecting member 32 and the first mounting block 33 provides a degree of rotational freedom, allowing the upper connecting member 32 to rotate around the hinge point.

[0033] By designing the first fixing clip as an adjustable clamping structure, the connecting device of this invention can be easily and quickly installed on brackets 10 of different diameters, improving the versatility and ease of installation of the device. Simultaneously, the hinged connection between the upper connecting member 32 and the first mounting block 33 provides a certain degree of flexibility to the upper connecting assembly 30. This flexibility is the basis for realizing the angle adjustment of the base station 20, as it allows the base station 20 to rotate around the hinge point of the upper connecting assembly 30, thereby cooperating with the adjustment mechanism in the lower connecting assembly 40 to achieve pitch angle adjustment. Therefore, this embodiment, through the optimized design of the connection structure between the first fixing clip and the upper connecting member 32 in the upper connecting assembly 30, enhances the adaptability and ease of installation of the device, and provides the necessary structural support for the realization of the overall angle adjustment function. Compared to technical solutions that only limit the upper connecting assembly to clamping the bracket and connecting it to the base station, this embodiment provides more specific and easier-to-implement structural details, improving the operability and reliability of the solution.

[0034] See Figure 1 and Figure 4In another specific embodiment of this utility model, the second fixing clip in the lower connecting assembly 40 is configured to consist of a second sub-clamp 411 and a second female clamp 412 connected by bolts. This structure allows the second fixing clip to adjust the size of its clamping opening by tightening or loosening the bolts, thereby accommodating the lower part of the bracket 10 with different diameters. The lower connecting member 42 is configured to be fixedly connected at one end to the second female clamp 412 of the second fixing clip, for example, by welding, riveting, or bolting, or the lower connecting member 42 and the second female clamp 412 are integrally formed. In this embodiment, the two are fixedly connected by integral forming. The other end of the lower connecting member 42 is connected to the second mounting block 43 through an adjusting assembly 50. This connection method is different from simple fixing or hinge, but is achieved through the adjusting assembly 50 as an intermediary, which allows an adjustable relative positional relationship between the lower connecting member 42 and the second mounting block 43.

[0035] The second fixing clamp uses a combination of a second sub-clamp 411 and a second female clamp 412 connected by bolts. Its technical feature is that it provides an adjustable clamping structure for securely fixing the lower connecting assembly 40 to the lower part of the bracket 10, and is compatible with brackets of different specifications. The fixed connection between the lower connecting member 42 and the second female clamp 412 of the second fixing clamp ensures a rigid connection between the two, allowing for effective transmission of clamping force. The other end of the lower connecting member 42 is connected to the second mounting block 43 via an adjusting component 50. Its technical feature is that this connection integrates an angle adjustment function. Specifically, the adjusting component 50 is positioned between the lower connecting member 42 and the second mounting block 43. By adjusting the movement of the adjusting component 50, the relative position between the lower connecting member 42 and the second mounting block 43 is changed, thereby achieving angle adjustment of the base station 20 connected to the second mounting block 43.

[0036] By designing the second fixing clip as an adjustable clamping structure, the connecting device of this utility model can be easily and quickly installed on the lower part of brackets 10 of different diameters, improving the versatility and ease of installation of the device. More importantly, this embodiment clarifies that the lower connecting member 42 and the second mounting block 43 are connected through the adjusting component 50, which provides a specific structural basis for realizing the angle adjustment function of the base station 20. As a bridge connecting the second fixing clip and the adjusting component 50, the lower connecting member 42's fixed connection with the second female clip 412 ensures the effective transmission of clamping force, while its connection with the adjusting component 50 makes it possible to change the angle of the base station 20 through the adjusting component 50. Therefore, this embodiment enhances the adaptability and ease of installation of the device through the optimized design of the connection structure between the second fixing clip and the lower connecting member 42 in the lower connecting component 40, and provides key structural support for the realization of the overall angle adjustment function. Compared with the technical solution that only limits the lower connecting component to clamping the bracket and connecting it to the base station, this embodiment provides more specific and easier-to-implement structural details, especially highlighting the connecting role of the adjusting component between the lower connecting member and the second mounting block, improving the operability and reliability of the solution.

[0037] See Figure 3 and Figure 4 In one specific embodiment of this utility model, the first sub-clamp 311 and the first female clamp 312 of the first fixing clamp in the upper connecting assembly 30, and the second sub-clamp 411 and the second female clamp 412 of the second fixing clamp in the lower connecting assembly 40, all have C-shaped grooves on their inner surfaces that contact the bracket 10. The curvature of these C-shaped grooves matches the shape of the bracket 10. For example, in this embodiment, the bracket 10 is cylindrical, and the C-shaped grooves are designed to have corresponding arc shapes. When the first sub-clamp 311 and the first female clamp 312 clamp the bracket 10 with bolts, the outer surface of the bracket 10 can fit tightly into the C-shaped grooves formed by the two. Similarly, when the second sub-clamp 411 and the second female clamp 412 clamp the bracket 10 with bolts, the outer surface of the bracket 10 can also fit tightly into the C-shaped grooves formed by the two.

[0038] The C-groove is a specific shape feature on the clamping surface of the retaining clamp, characterized by its curved surface's ability to closely conform to the outer surface of the cylindrical or similarly shaped support 10. The primary purpose of this design is to increase the contact area between the retaining clamp and the support 10, and to improve the shape matching of the contact surfaces. By employing the C-groove, the retaining clamp can distribute clamping force more evenly and provide better coverage. This shape matching enhances clamping stability and reduces the likelihood of relative slippage under stress or vibration. As one possible implementation, the depth and curvature of the C-groove can be designed according to the expected diameter range of the support 10 to ensure a good fit.

[0039] By providing C-shaped grooves on the clamping surfaces of the first and second clamps, the connection device of this invention can better adapt to cylindrical or other brackets 10 with similar cross-sectional shapes, significantly improving the connection stability and adaptability between the AAU device and the bracket 10. The C-shaped grooves increase the contact area between the clamps and the bracket 10, thereby increasing the clamping force and making the clamping more secure and reliable. This is crucial for 5G AAU devices that bear a weight of approximately 40kg, effectively preventing displacement or loosening of the device under the influence of external factors such as wind load and vibration, ensuring the long-term stable operation of the base station. Simultaneously, this design also increases the applicability of the device to brackets of different shapes, improving the product's versatility. Therefore, this embodiment, through optimized design of the clamping surface shape, enhances the clamping performance and stability of the device, providing a strong guarantee for the reliability of the overall connection device. Compared to the cited claims, this embodiment provides more specific and effective clamping structure details, improving the practicality and reliability of the solution.

[0040] See Figure 1 , Figure 3 and Figure 4 In one specific embodiment of this utility model, the connection between the connecting device and the base station 20 is achieved through a first mounting block 33 and a second mounting block 43. Both the first mounting block 33 and the second mounting block 43 are configured to include a connecting plate and a hinge seat. The connecting plate is designed to fit against the back of the base station 20 and is fixedly connected to the base station 20 by fasteners such as bolts. The hinge seat is disposed on the connecting plate and is used for hinged connection with other components of the connecting device. Specifically, the hinge seat of the first mounting block 33 is used for hinged connection with the upper connecting member 32 of the upper connecting assembly 30, while the hinge seat of the second mounting block 43 is used for hinged connection with the connecting member 53 in the adjusting assembly 50 of the lower connecting assembly 40. These hinged connections allow the upper connecting member 32 and the connecting member 53 to rotate within a certain range relative to the mounting blocks 33 and 43.

[0041] The first mounting block 33 and the second mounting block 43 consist of a connecting plate and a hinge seat. Their technical feature is that they provide a standardized interface for reliably securing the connecting device to the base station 20 and provide hinge points for the upper connecting assembly 30 and the lower connecting assembly 40. The connecting plate is bolted to the back of the base station 20, ensuring a stable connection capable of withstanding the weight of the AAU equipment and external loads. The hinge seat design provides a rotation axis for the upper connecting member 32 and the connecting member 53, allowing the base station 20 to be angularly adjusted around these hinge points.

[0042] By designing the first mounting block 33 and the second mounting block 43 to include a connecting plate and a hinge seat, the connection device of this utility model can be conveniently and reliably installed on the back of the base station 20, and provides a stable hinge point for the upper connecting component 30 and the lower connecting component 40. The connecting plate allows the device to be fixed to the base station 20 through a standardized bolt connection, improving the convenience and compatibility of installation. The hinge seat ensures that the upper connecting member 32 and the connecting member 53 can rotate flexibly, which is crucial for realizing the angle adjustment function of the base station 20. This structural design enables the device to stably support heavy AAU equipment and provides a reliable mechanical foundation for subsequent angle adjustment. Therefore, this embodiment, through the optimized design of the composition and function of the mounting blocks, enhances the connection stability between the device and the base station and the flexibility of angle adjustment, providing strong support for the practicality of the overall connection device. Compared with the cited claims, this embodiment provides more specific and effective structural details of the mounting blocks, improving the operability and reliability of the solution.

[0043] See Figure 4 In one specific embodiment of this utility model, a handle 512 is pre-installed at the bottom of the adjusting bolt 511 in the adjusting assembly 50. The handle 512 is fixedly connected to or integrally formed with the bottom of the adjusting bolt 511, and its shape and size are designed to facilitate direct gripping and rotation by the operator. For example, in this embodiment, the handle 512 is a laterally extending rod-like structure. By rotating the handle 512, the adjusting bolt 511 can be rotated, thereby adjusting the angle of the base station 20.

[0044] The handle 512 is an additional structure located at the bottom of the adjusting bolt 511. Its technical feature is that it provides an interface for directly operating the adjusting bolt 511 without the need for additional tools. Traditionally, turning bolts usually requires tools such as wrenches and screwdrivers. With the pre-installed handle 512, the operator can adjust it directly by hand, greatly simplifying the operation process. The shape and material of the handle 512 can be optimized according to actual needs to provide a better grip and turning efficiency. For example, it can be made of non-slip materials or have an ergonomic design.

[0045] By pre-setting a handle 512 at the bottom of the adjusting bolt 511, the connecting device of this utility model significantly improves the convenience and efficiency of angle adjustment operation. Installation or maintenance personnel can fine-tune the angle of the AAU equipment anytime, anywhere without carrying additional tools. This is especially important for operations at heights or in confined spaces, greatly reducing operational difficulty and safety risks, and saving valuable time. This tool-free adjustment design makes on-site operation more flexible and convenient, improving work efficiency. Therefore, this embodiment, by adding a handle to the bottom of the adjusting bolt, greatly optimizes the user experience and enhances the practicality of the device. Compared to the cited claims, this embodiment provides a more convenient and user-friendly operating method, improving the ease of use of the solution.

[0046] See Figure 4 and Figure 5 In one specific embodiment of this utility model, a support tube 421 is fixedly connected to the lower connecting member 42 of the lower connecting assembly 40. The support tube 421 is a hollow cylindrical shape, forming a cavity 422 inside. The adjusting bolt 511 in the adjusting assembly 50 and the connecting tube 521 of the adjuster 52 are both fitted into the cavity 422 of the support tube 421. Specifically, the threaded portion of the adjusting bolt 511 passes through the threaded hole on the lower connecting member 42, and its top extends into the cavity 422 of the support tube 421. The connecting tube 521 at the bottom of the adjuster 52 is also fitted into the cavity 422 and rotatably engages with the top of the adjusting bolt 511. The support tube 421 can be fixed to the lower connecting member 42 by welding or integral molding, and its position and length are designed to accommodate the adjusting bolt 511 and the connecting tube 521, providing support and guidance for them.

[0047] The support pipe 421 and its cavity 422 provide support and guidance for the adjusting bolt 511 and the connecting pipe 521. Its technical feature lies in enhancing the overall stability of the adjusting mechanism through a sleeve connection. The support pipe 421 is fixed to the lower connector 42, providing external constraint and support for the adjusting bolt 511 and the connecting pipe 521. The adjusting bolt 511 and the connecting pipe 521 are sleeved within the cavity 422, making their vertical movement and rotation more stable and less prone to swaying or deflection. This sleeve structure effectively reduces the bending or deformation of the adjusting bolt 511 under stress (such as the weight of the AAU equipment or external wind load), improving the rigidity and load-bearing capacity of the adjusting mechanism.

[0048] By providing a support tube 421 on the lower connector 42 and fitting the adjusting bolt 511 and the connecting tube 521 into the cavity 422 of the support tube 421, the connection device of this utility model significantly improves the structural stability of the adjustment mechanism. This sleeved support structure provides additional support and guidance for the adjusting bolt 511 and the connecting tube 521, effectively preventing them from deforming or becoming unstable under heavy loads or harsh environments, thereby ensuring the smoothness and accuracy of the angle adjustment process. Especially when facing AAU equipment weighing approximately 40 kg and external loads such as strong winds, this enhanced structural stability is crucial for ensuring the reliability and service life of the device. Therefore, this embodiment, by adding a support tube and adopting a sleeved structure, enhances the deformation resistance and stability of the adjustment mechanism, providing a strong guarantee for the reliability of the overall connection device. Compared with the cited claims, this embodiment provides a more robust and reliable adjustment mechanism support structure, improving the durability and reliability of the solution.

[0049] See Figure 5 In one specific embodiment of this utility model, the bottom end of the connecting pipe 521 of the regulator 52 is designed to have a mounting hole 522. The size and shape of the mounting hole 522 are designed to fit with the top end of the adjusting bolt 511, allowing the top end of the adjusting bolt 511 to be embedded in the mounting hole 522. Within the mounting hole 522, the top end of the adjusting bolt 511 is allowed to rotate freely, while simultaneously, the top end of the adjusting bolt 511 abuts against the bottom of the connecting pipe 521 within the mounting hole 522. This abutting relationship ensures that the vertical movement of the adjusting bolt 511 can be effectively transmitted to the connecting pipe 521, thereby driving the regulator 52 and the connector 53 to move. The specific depth and diameter of the mounting hole 522 are designed to match the size of the top end of the adjusting bolt 511.

[0050] The mounting hole 522 is a structure located at the bottom end of the connecting pipe 521 for engaging with the top of the adjusting bolt 511. Its technical feature is that it provides a stable rotational support point and force transmission interface. The top of the adjusting bolt 511 is embedded in the mounting hole 522 and can rotate within it, ensuring that the adjusting bolt 511 maintains a stable axis during rotation and reducing radial wobble. Simultaneously, the design of the top of the adjusting bolt 511 abutting against the connecting pipe 521 provides a reliable axial force transmission path, allowing the vertical thrust or tension of the adjusting bolt 511 to directly act on the connecting pipe 521, thereby driving the entire adjusting mechanism. This embedded, rotating engagement, and abutting connection method helps improve the motion accuracy and stability of the adjusting mechanism.

[0051] By providing a mounting hole 522 at the bottom of the connecting pipe 521 of the adjuster 52, and embedding the top of the adjusting bolt 511 into the hole and pressing against the connecting pipe 521, the connection device of this utility model significantly improves the stability and accuracy of the adjusting mechanism. The stable rotational engagement of the top of the adjusting bolt 511 within the mounting hole 522 effectively reduces shaking and deviation during the adjustment process, making angle adjustment smoother and more precise. Simultaneously, the design of the top of the adjusting bolt 511 pressing against the connecting pipe 521 ensures direct and effective force transmission, improving the responsiveness and controllability of the adjustment action. This precise connection method, combined with the external support provided by the support pipe, further enhances the overall rigidity and deformation resistance of the adjusting mechanism. Especially for heavy-duty AAU equipment, this stability is crucial for achieving precise angle adjustment and ensuring the long-term reliable operation of the equipment. Therefore, this embodiment, through optimized design of the connection method between the adjusting bolt and the connecting pipe, improves the motion accuracy and stability of the adjusting mechanism, providing a strong guarantee for the reliability of the overall connection device. Compared with the cited claims, this embodiment provides a more precise and reliable connection structure between the adjusting bolt and the connecting pipe, improving the adjustment performance and durability of the solution.

[0052] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
