Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment, and further relates to a bearing assembly and a photovoltaic tracking bracket. Background Art

[0002] In the prior art, the rotating contact surface between the main shaft structure and the bearing of a photovoltaic tracking bracket is typically designed as an arc surface, with the centerline of the arc serving as the rotation centerline. Once the rotating connection structure is fixed, the main shaft's rotation centerline is also limited. When installed on a sloped surface, this limits the adjustable range of the main shaft, making it difficult to ensure the main shaft's stability during rotation. Furthermore, the rotating contact surface between the synchronous shaft and the bearing is also configured in the same manner in the prior art. In photovoltaic tracking brackets that utilize a multi-point synchronous drive system, the existing installation structure of the synchronous shaft is significantly restricted by the terrain slope. When the slope is steep, it is prone to jamming, causing the photovoltaic bracket to fail to operate normally, impacting the stability and power generation efficiency of the entire photovoltaic system.

[0029] Compared with the prior art, the bearing assembly and photovoltaic tracking bracket provided in this application have at least one of the following beneficial effects:

[0030] 1. In this application, the bearings for mounting the main shaft and the synchronous shaft are all spherical bearings. The spherical structure of the spherical bearings provides greater freedom and adjustment capabilities, so that the photovoltaic tracking bracket can automatically compensate for errors during the installation process and adapt to uneven ground. This not only simplifies the installation process and reduces the workload of the installers, but also improves the stability and reliability of the system.

[0031] 2.

The second split bearing seat is a common part for the main shaft installation and the synchronous shaft installation, thereby saving space and avoiding the increase in component height caused by having to raise the bearing seat of the main shaft part to install the synchronous shaft, which is beneficial to lowering the center of gravity of the photovoltaic tracking bracket and improving the stability and wind resistance of the system.

[0033] 4. In the present application, the positioning accuracy of the first spherical bearing in the first mounting portion is enhanced by the movable docking of the first guide portion and the second guide portion, thereby ensuring the stability and reliability of the bearing during operation; at the same time, the design effectively avoids the axial deviation or outward movement of the first spherical bearing during rotation, thereby reducing the possible wear and damage to the bearing and extending the service life of the bearing.

[0034] 5. In the column structure of the present application, the connecting portion can be movably connected to the column body, so that the height of the bearing assembly can be adjusted synchronously with the connecting portion, thereby adapting to different installation environments and needs, providing greater flexibility, especially in complex or slope-changing terrain, and can be quickly adjusted to adapt to changes in ground height.

DETAILED DESCRIPTION

[0051] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0053] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0054] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly.

Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0056] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0057] The design goal of photovoltaic tracking brackets is to maximize the amount of sunlight received by solar panels by adjusting the angle of the solar panels to track the movement of the sun. Although tracking bracket technology has made certain progress, existing designs are often difficult to adapt to terrain with large slope variations, such as mountainous areas. In traditional solutions, the rotating contact surface of the main beam structure is designed as an arc surface, and its centerline is the rotation centerline. Once the rotating connection structure is fixed, the rotation centerline of the main beam structure is also limited. This limits the adjustable range when installing on sloping surfaces and makes it difficult to ensure the stability of the main shaft during rotation.

[0058] Similarly, in photovoltaic trackers that utilize a multi-point synchronous drive system, the synchronous axis uses a similar mounting structure to the main axis, which is significantly limited by the slope of the terrain. When the slope is steep, it is prone to jamming, causing the photovoltaic tracker to malfunction, affecting the stability and power generation efficiency of the entire system.

[0059] In response to the problems in the prior art, the bearing assembly provided in this application can provide greater flexibility and adaptability, thereby improving the stability and reliability of the photovoltaic tracking bracket and making the application range of the photovoltaic tracking bracket wider.

[0060] Reference Manual Figure 1 and Figure 2The present application provides a bearing assembly comprising a first spherical bearing assembly and a second spherical bearing assembly. The first spherical bearing assembly comprises a first spherical bearing 31 and a first bearing seat, and the second spherical bearing assembly comprises a second spherical bearing 32 and a second bearing seat. The first spherical bearing 31 and the second spherical bearing 32 respectively have a first installation space 310 and a second installation space 320 extending axially therethrough. The first installation space 310 is used to install the main shaft 1 of the photovoltaic tracking bracket, and the second installation space 320 is used to install the synchronous shaft 2 of the photovoltaic tracking bracket. The first bearing seat and the second bearing seat are respectively provided with a first installation portion 410 and a second installation portion 420 extending axially therethrough, for installing the first spherical bearing 31 and the second spherical bearing 32 respectively. It is understandable that the contours of the first installation space 310 and the second installation space 320 match the cross-sectional shapes of the main shaft 1 and the synchronous shaft 2 respectively.

[0061] In this embodiment, by using spherical bearings as the main shaft bearings and synchronous shaft bearings, the photovoltaic tracking bracket can better adapt to various terrains, improving its applicability and stability. It is understandable that spherical bearings have a certain degree of flexibility. In mountainous areas or other areas with a certain slope, traditional cylindrical bearings, due to their fixed rotation centerline, often have difficulty adapting to uneven ground, resulting in a complex installation process and poor bracket stability. In contrast, the spherical bearings in this embodiment can autonomously adjust their position to compensate for the tilt and unevenness of the ground, ensuring that the main shaft 1 and synchronous shaft 2 always maintain the correct relative position and angle.

[0062] At the same time, the ball bearing provides greater freedom, allowing the main shaft 1 and the synchronous shaft 2 to adjust their angles more flexibly to adapt to changes in the position of the sun, helping to maximize the amount of sunlight received by the photovoltaic panels and thus improve power generation efficiency.

[0063] Furthermore, the bearing seat is designed as a split structure, allowing at least one of the first mounting portion 410 and the second mounting portion 420 to be adjusted to an open structure, facilitating the rapid installation and removal of the first spherical bearing 31 and / or the second spherical bearing 32. As will be appreciated, in traditional one-piece bearing seat designs, once the bearing body is installed in the bearing seat, its position and angle are fixed, making it difficult to adjust or replace. However, the split design of the bearing seat in this embodiment allows for rapid adjustment or replacement of the bearing without disassembling the entire structure, greatly improving installation and maintenance efficiency.

[0064] In addition, the split design of the bearing seat in this embodiment not only improves installation and maintenance efficiency, but also greatly enhances adaptability to complex terrain. In mountainous or uneven areas, there are certain changes in ground slope. In this embodiment, the outer contours of the first and second spherical bearings are spherical structures. Similarly, the inner contours of the first and second mounting portions 410 and 420 are spherical structures that match the outer contours of the first and second spherical bearings, respectively. This allows the split-design bearing seat to quickly adapt to these changes by adjusting the installation form of the first and second mounting portions 410 and 420 relative to the main shaft 1 and synchronous shaft 2, or the specific form of the mounting portions, ensuring precise alignment and stable operation of the main shaft 1 and synchronous shaft 2.

[0065] Alternatively, the bearing seat in this embodiment can be made of high-strength steel, aluminum alloy, or other suitable materials to ensure structural strength and durability while reducing weight. This material selection not only improves the bearing seat's load-bearing capacity but also helps it withstand adverse weather conditions and environmental influences such as corrosion and sandstorms.

[0066] Based on the above, if Figure 3 and Figure 4 As shown, the first bearing seat includes a first split bearing seat 41 and a second split bearing seat 42. The first split bearing seat 41 and the second split bearing seat 42 are interconnected by a first connecting structure, and together form a first mounting portion 410 for mounting the first spherical bearing 31, that is, the main shaft bearing seat of the photovoltaic tracking bracket is formed by the above two split bearing seats.

[0067] As will be appreciated, the first and second split bearing seats 41, 42 can be manufactured and processed independently, then quickly assembled at the installation site. This reduces the volume and weight of the mounting bracket during transportation, a significant advantage when transporting the bracket to remote or hard-to-reach areas. Furthermore, the split design allows operators to fine-tune the bearing seats during installation to ensure precise installation of the first spherical bearing 31, thereby improving the tracking accuracy and stability of the entire photovoltaic tracking system.

[0068] The first connection structure in this embodiment can be implemented in a variety of ways, such as using adjustable bolts, pins or clamps, and these connection elements can be provided with quick release and locking components so that they can be quickly adjusted when needed.

[0069] In one embodiment, based on the above embodiments, as Figure 3As shown, the second bearing seat includes a third split bearing seat 43 and a limiting portion 421 arranged on the second split bearing seat 42. The third split bearing seat 43 and the limiting portion 421 arranged on the second split bearing seat 42 are connected, and the two together form a second mounting portion 420 to install the second spherical bearing 32, thereby forming a bearing seat for installing the synchronization shaft 2 of the photovoltaic tracking bracket.

[0070] like Figure 6 As shown, the second split bearing seat 42 has two mounting ends in opposite directions, one end is used to connect with the first split bearing seat 41 to install the main shaft 1, and the other end is used to connect with the third split bearing seat 43 to install the synchronous shaft 2, so that the second split bearing seat 42 can support the installation of two bearing bodies in space at the same time without increasing the height.

[0071] As can be understood, the second split bearing seat 42 serves as a common mounting element for the main shaft 1 and the synchronous shaft 2. This eliminates the need to raise the main shaft 1 to accommodate the synchronous shaft 2, thus avoiding an increase in component height and reducing the required space, making the entire photovoltaic tracking system more compact. Furthermore, the reduced overall height of the photovoltaic tracking system not only reduces material usage but also lowers the center of gravity of the entire structure, thereby improving the system's stability and wind resistance.

[0072] In addition, the second connection structure in this embodiment can be designed to be similar to the first connection structure, that is, a detachable and adjustable connection is achieved through tools such as bolts or clamps.

[0073] More specifically, Figure 12 and Figure 14 As shown, the second connection structure adopts the combination of bolts and nuts. At the same time, through holes 80 are provided on the limiting portion 421 of the second split bearing seat 42 and the third split bearing seat 43 for the bolts to pass through, so as to relatively fix the second split bearing seat 42 and the third split bearing seat 43; moreover, a number of protrusions 4211 are provided on the limiting portion 421. After the bolts and nuts are fixed, the protrusions 4211 rest against part of the edge of the nut, making the nut unable to rotate, preventing the nut from loosening due to vibration or impact, ensuring the long-term stability of the connection structure, and reducing maintenance costs and potential safety risks.

[0074] In one embodiment, Figure 4 As shown, the first connection structure includes a hinge part 51 and a locking structure. The corresponding one side ends of the first split bearing seat 41 and the second split bearing seat 42 are connected by the hinge part 51, and the corresponding other side ends of the first split bearing seat 41 and the second split bearing seat 42 are provided with a locking structure, so that the two split bearing seats can generate relative rotation under the action of the hinge part 51, and after rotating into place, the relative fixation of the two is completed by the locking structure.

[0075] Among them, the design of the hinge part 51 allows the first split bearing seat 41 and the second split bearing seat 42 to still maintain a certain degree of mobility after being connected, so that they can adapt to different installation angles and positions; and the locking structure can ensure that after the hinge part 51 is rotated into place, the two split bearing seats can be accurately fixed to prevent displacement or loosening during operation, thereby improving the stability and reliability of the entire photovoltaic tracking system.

[0076] In this embodiment, the locking structure can be designed as a bolt, a clamping device or other mechanical locking devices, which can quickly lock the positions of the two split bearing seats after the hinge portion 51 is rotated into place.

[0077] Specifically, such as Figure 5 As shown, the locking structure includes a swing bolt 52 and a locking nut 53. One end of the swing bolt 52 is connected to one end of one of the split bearing seats via a rotating shaft, and the other end is screwed into the locking nut 53. A recess is provided at the corresponding end of the other split bearing seat. When the swing bolt 52 is rotated into place and locked, it embeds into the recess. At the same time, abutment is formed between the locking nut 53 and the end of the corresponding split bearing seat to prevent loosening due to vibration or wind, thereby improving the stability and reliability of the entire photovoltaic tracking bracket.

[0078] In addition, by adjusting the position of the locking nut 53 on the movable bolt 52, the gap between the two split bearing seats can be adjusted, which greatly facilitates installation and maintenance, especially when fine-tuning is required to adapt to different terrains or installation conditions.

[0079] In one embodiment, at least one discharge port 421 is provided on the second split bearing seat 42 . The discharge port 421 penetrates the lower end surface of the first mounting portion 410 and is used to discharge impurities between the first mounting portion 410 and the first spherical bearing 31 .

[0080] Understandably, dust and liquid impurities are common causes of bearing wear and failure in the operating environment of photovoltaic tracking mounts. Providing a discharge port 421 on the second split bearing seat 42 effectively removes these impurities, reducing damage to the bearing and thereby extending its service life. Furthermore, removing impurities helps keep the bearing clean, reduces friction, and improves its operating efficiency, ensuring optimal bearing operation and minimizing performance degradation caused by impurity accumulation.

[0081] In one embodiment, Figure 7 As shown, a continuous or discontinuous first guide portion 3101 is provided on the outer periphery of the first spherical bearing 31 .

[0082] At the same time, if Figure 4 As shown, the first mounting portion 410 has an annular profile, and a second guide portion 4101 is provided on its inner circumference. The second guide portion 4101 can match the first guide portion 3101. When the first spherical bearing 31 is installed in place, the two guide portions are movably docked to ensure the stability of the bearing body during operation, thereby improving the operation accuracy and reliability of the entire photovoltaic tracking bracket and preventing the bearing from jumping out.

[0083] In a specific implementation, the first guide portion 3101 can be designed as a protrusion or groove distributed along the outer circumference of the first spherical bearing 31, while the second guide portion 4101 is a corresponding structure on the inner circumference of the first mounting portion 410. During installation, the first guide portion 3101 on the first spherical bearing 31 and the second guide portion 4101 on the first mounting portion 410 can be aligned and connected relative to each other through simple manual or mechanical operations, achieving quick and stable installation.

[0084] Furthermore, the first guide portion 3101 is configured as a limiting protrusion, and the second guide portion 4101 is configured as a limiting groove, with the limiting protrusion and the limiting groove forming a movable joint. To ensure the flexibility of the ball bearing, in this embodiment, the width of the limiting groove is greater than the width of the limiting protrusion, allowing the ball bearing to have a certain amount of adjustment space during operation of the bracket to accommodate installation errors or changes.

[0085] Among them, there are at least two limiting protrusions, which are symmetrically distributed on the outer periphery of the first spherical bearing 31, and the limiting groove is set on part of the inner periphery of the first mounting portion 410, which can accurately limit the rotation range of the first spherical bearing 31 and prevent the bearing from being offset or over-rotated during operation, thereby improving the reliability of the bearing operation.

[0086] Specifically, in this embodiment, the limiting grooves are provided along a portion of the inner circumference of the first mounting portion 410. This means that limiting grooves are not provided along the entire inner circumference, but rather are provided in specific areas as needed. This design allows the necessary rotational restriction of the bearing body to be provided without sacrificing the overall strength of the mounting portion.

[0087] The specific location and number of the limiting grooves can be adjusted based on the size and rotation requirements of the first spherical bearing 31. For example, if the first spherical bearing 31 needs to rotate within a larger range, the limiting grooves can be placed within a wider area to provide sufficient restraint. Conversely, if the rotation range is smaller, the limiting grooves can be concentrated within a smaller area to achieve more precise control.

[0088] In one embodiment, two limiting protrusions are symmetrically distributed on the outer periphery of the first spherical bearing 31, and the two limiting protrusions are located on opposite sides of the bearing body, while two limiting grooves are also symmetrically distributed on the inner periphery of the first mounting portion 410, and the corresponding limiting grooves are also located on opposite sides of the first mounting portion 410, matching the positions of the limiting protrusions.

[0089] However, in other implementations, it may be necessary to restrict the rotation of the bearing body at multiple points to increase the stability and reliability of the system. In this case, multiple limiting protrusions can be provided on the outer periphery of the first spherical bearing 31, and a series of evenly distributed limiting grooves can be designed on the inner periphery of the first mounting portion 410.

[0090] In one embodiment, the reference Figure 7 The first spherical bearing 31 is a split type arrangement, and the first spherical bearing 31 includes a first bearing split 311 and a second bearing split 312. A first positioning structure 61 is provided between the first bearing split 311 and the second bearing split 312, which is used for the mutual docking of the two to form a first installation space 310 for installing the main shaft 1 of the photovoltaic tracking bracket.

[0091] Similarly, in some implementations, reference is made to the appended Figure 8 The second spherical bearing 32 includes a third bearing body 321 and a fourth bearing body 322, which are connected to each other via a second positioning structure 62 to form a second installation space 320. The split arrangement of the bearing body in this embodiment makes installation and removal of the bearing body relative to the main shaft 1 or synchronous shaft 2 easier and more flexible.

[0092] The bearing parts are docked with each other through the first positioning structure 61 or the second positioning structure 62, so that the docking between the bearing parts is more precise, thereby ensuring the stability of the bearing during operation.

[0093] Specifically, the first positioning structure 61 includes a first positioning column 611 and a first positioning hole 610. Figure 7 At least one first positioning column 611 is provided on the first bearing body 311, and at least one first positioning hole 610 matching the first positioning column 611 is provided on the second bearing body 312. When the two bearing bodies are docked, the first positioning column 611 is inserted into the first positioning hole 610 to ensure the correct alignment of the two bearing bodies, thereby improving the accuracy and efficiency of assembly; the second positioning structure 62 is also similar. Figure 8 As shown, corresponding second positioning columns 621 and second positioning holes 620 are respectively provided on the two bearing parts, which will not be described again here.

[0094] Furthermore, the bearing assembly also includes a limiting structure. For the first spherical bearing 31, the limiting structure is provided on the first bearing body 311 or the second bearing body 312 to prevent the two bearing bodies from separating in the radial direction.

[0095] Similarly, for the second spherical bearing 32 , a limiting structure is also provided on the corresponding third bearing sub-body 321 or fourth bearing sub-body 322 to ensure that the two bearing sub-bodies will not separate in the radial direction.

[0096] As can be understood, the positioning structure effectively reduces the gap between the first spherical bearing 31 and the main shaft 1, thereby reducing the possibility of main shaft 1 not rotating smoothly during operation of the photovoltaic tracking bracket. The positioning structure also reduces the gap between the second spherical bearing 32 and the synchronous shaft 2, ensuring coordinated movement between the main shaft 1 and the synchronous shaft 2.

[0097] Here, the limiting structure provided on the first ball bearing 31 is used as an example. Figure 7 As shown, the limiting structure may include a limiting bolt 631 and a limiting nut 632. The limiting bolt 631 passes through the assembly holes 630 set on the first bearing split 311 and the second bearing split 312 at the same time, and is locked with the limiting nut 632, thereby realizing the connection and limitation of the two bearing splits. At the same time, the contour of the assembly hole 630 that cooperates with the limiting nut 632 can be set to a non-circular contour that is compatible with the outer contour of the limiting nut 632, thereby preventing the limiting nut 632 from loosening during the operation of the photovoltaic tracking bracket, which can improve safety and reliability.

[0098] In another embodiment, the retaining structure may include buckles and slots. Specifically, one or more buckles are provided on the end or outer edge of the first bearing body 311. The buckles can be made of plastic or metal and have elasticity. The second bearing body 312 is designed with corresponding slots for receiving the buckles. When the two bearing bodies are aligned and pressed together, the buckles engage the slots, thereby achieving position retention.

[0099] In one embodiment, the reference Figure 9 According to another aspect of the present application, the present application further provides a photovoltaic tracking bracket, including a main shaft 1, a synchronization shaft 2, the above-mentioned bearing assembly and a column structure 7.

[0100] Among them, the main shaft 1 and the synchronous shaft 2 are installed in the bearing assembly, and the bearing assembly is installed on the top of the column structure 7. It can be understood that it has been explained above that the reliability and adaptability of the photovoltaic tracking bracket can be improved by the first spherical bearing 31 and the second spherical bearing 32 in the bearing assembly, which will not be repeated here.

[0101] Based on the above, if Figure 10As shown, the column structure 7 includes a column body 71 and a connecting portion 72. The connecting portion 72 can be movably connected to the column body 71, so that the height of the connecting portion 72 is adjustable. The bottom of the bearing assembly is connected to the top of the connecting portion 72. Therefore, when the height of the connecting portion 72 is adjusted, the height of the bearing assembly can also be adjusted synchronously.

[0102] In this embodiment, the photovoltaic tracking bracket can adapt to installation requirements of different heights through the height-adjustable connection portion 72, especially in areas where the ground height varies greatly. The installer can quickly adjust the installation of the photovoltaic tracking bracket according to the actual ground height.

[0103] In practice, the connection portion 72 can be movably connected to the column body 71 in a variety of ways, such as using threads, hinges, sliding rails, or other mechanical adjustment devices, allowing the connection portion 72 to move up and down on the column body 71 to achieve height adjustment. The bottom of the bearing assembly can be designed with an interface that adapts to the top of the connection portion 72 to ensure that the bearing assembly can move smoothly with the connection portion 72 during height adjustment.

[0104] More specifically, the column body 71 is provided with at least two or more first adjustment holes 710 , which are arranged along the height direction of the column body 71 and are used to form a connection with the connecting portion 72 .

[0105] During installation, the height of the bearing assembly relative to the column body 71 can be adjusted by adjusting the connection holes between the connecting portion 72 and the column body 71, allowing the photovoltaic tracking bracket to adapt to different terrains and installation requirements. Correspondingly, height adjustment holes can also be provided on the connecting portion 72 to achieve this hole position adjustment. Furthermore, the first adjustment holes 710 can be evenly or unevenly distributed on the column body 71 to provide different height adjustment options.

[0106] like Figure 10 As shown, there are two connecting parts 72, which are symmetrically arranged on the opposite side walls of the column body 71, and the bottom of the bearing assembly is connected to the two connecting parts 72 at the same time, forming a symmetrical design, which is beneficial to improving the stability and balance of the structure and reducing the tilt or distortion caused by wind or gravity.

[0107] In one embodiment, Figure 11 As shown, a second adjustment hole 720 is provided on the upper surface of the connecting portion 72 , and the second adjustment hole 720 is used to form a connection with the bearing assembly.

[0108] In one case, at least two or more second adjustment holes 720 are provided on the upper surface of the connecting portion 72, which are similar to the common circular hole structure. By adjusting the connection hole position between the connecting portion 72 and the bearing assembly, the horizontal position of the bearing assembly relative to the connecting portion 72 can be synchronously adjusted. The installer can select the appropriate hole position for adjustment according to the actual installation conditions and terrain, thereby improving the flexibility and adaptability of the installation process.

[0109] In another case, the second adjustment hole 720 provided on the upper surface of each connecting portion 72 is a waist-shaped hole. When the bearing assembly is not locked, the bearing assembly can slide along the track of the waist-shaped hole and be locked by bolts after being in place, which simplifies the operation to a certain extent.

[0110] Of course, in the above content, when the height of the bearing assembly is adjusted through the first adjustment hole 710, the waist-shaped hole design is also applicable, and the operator can fine-tune the position of the bearing assembly to a certain extent through the waist-shaped hole.

[0111] In addition, the first adjustment hole 710 and the second adjustment hole 720 can also be used in combination so that the height and horizontal position of the bearing assembly can be adjusted to ensure that the photovoltaic tracking bracket can remain stable under different terrain and environmental conditions, reducing the system load caused by installation errors or terrain changes.

[0112] In one embodiment, based on the above content, the connecting portion 72 is connected to the second split bearing seat 42 in the bearing assembly, specifically, as Figure 13 and Figure 14 As shown, the second adjustment hole 720 is connected to the through hole 80 on the limiting portion 421 by a combination of bolts and nuts. The raised portion 4211 provided on the limiting portion 421 can limit the rotation of the nut to prevent the bolt connection structure from loosening after installation, which is beneficial to improving the safety and stability of the photovoltaic tracking bracket.

[0113] It should also be noted that, in the present application, the protrusion 4211 provided on the stopper 421 can be discontinuous (similar to that shown in the accompanying drawings) or continuous. The discontinuous protrusion 4211 can abut against two opposite edges of the nut, while the continuous protrusion forms a continuous ridge. Both designs can effectively prevent the nut from accidentally loosening due to external forces, thereby improving the safety of the structure.

[0114] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be noted that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be considered as the scope of protection of the present application.
