Description

Technical Field

[0001] This utility model relates to the field of building decoration connection technology, and in particular to a self-locking universal connector for light steel keel. Background Technology

[0002] Dry-process decorative wall panels and light steel keel are inseparable and interdependent core components of modern building partition and ceiling systems. The light steel keel is the core supporting structure, forming the skeleton of the wall or ceiling, while the dry-process decorative wall panels are the finishing layer, the surface material covering the light steel keel skeleton. In actual construction, various connectors are needed to connect light steel keels of different specifications and shapes to build a stable keel frame. Existing light steel keel connectors typically use bolts, screws, and other additional fasteners for fixing. This connection method not only increases installation steps, making on-site operations complex and time-consuming, but also, after connection, the relative position and angle between the keels are usually fixed or can only be adjusted to a limited extent. This makes it difficult to make fine adjustments to the keel position during on-site installation, especially when dealing with irregular structures or achieving specific spatial layouts. This lack of multi-directional adjustment freedom is particularly inconvenient, affecting construction efficiency and accuracy. To address these problems, existing technologies urgently need improvement. Utility Model Content

[0003] This utility model discloses a self-locking universal connector for light steel keel, which aims to solve the problems of existing dry-process decorative wall panel light steel keel connectors requiring additional fasteners, complicated operation, and lack of multi-directional adjustment freedom.

[0004] The self-locking universal connector for light steel keel includes a base and a socket. A rotating connection component is installed on one side of the base, a mounting seat is installed on one side of the rotating connection component, and a plug slot component is provided on one side of the mounting seat. A plug connector component is provided on one side of the socket for inserting the plug connector component into the plug slot component, and the socket can rotate after insertion. Both the base and the socket have an installation port on one side for installing the keel in the installation port.

[0005] Furthermore, the rotating connection assembly includes a first connecting rod disposed on one side of the base, a rotating seat disposed at one end of the first connecting rod, a rotating block rotatably disposed within the rotating seat, and a second connecting rod disposed on one side of the rotating block, the other end of which is connected to one side of the mounting base.

[0007] Furthermore, the plug slot assembly includes a plug slot disposed on one side of the mounting base and two insertion holes disposed on the inner walls of the plug slot on both sides for connecting to the plug connector assembly, the insertion holes extending from the plug slot to the outer side of the mounting base.

[0008] Furthermore, the connector assembly includes two pads disposed on one side of the socket and two plugs disposed on the respective pads, the plugs being adapted to the socket for inserting the plugs into the socket.

[0009] Furthermore, guide grooves are provided on the inner walls of both sides of the insertion slot. These guide grooves are adapted to the insertion block and are used to guide the insertion block into the insertion hole. The guide grooves extend from one side of the insertion hole to the outside of the insertion slot.

[0010] Furthermore, one side of the insert block is provided with an inclined surface to cooperate with the guide groove to guide the insert block.

[0011] Furthermore, one side of the plug is provided with a snap-down part, which is used to limit the plug after it is inserted into the socket.

By connecting the socket and the mounting base with a self-locking connector, it achieves quick insertion and separation between the socket and the mounting base without the need for additional fasteners, simplifying the installation operation and improving construction efficiency. Simultaneously, by connecting the base and the mounting base with the universal connector, the mounting base can freely rotate and adjust relative to the base in multiple directions (such as horizontal, vertical, and angular), thereby enabling fine-tuning of the keel connected to the base and socket.

[0022] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] 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.

[0024] In the construction industry, light steel keel is widely used due to its excellent performance. However, when using existing connectors to build keel frames, additional bolts, screws, and other fasteners are often required. This not only increases the complexity and labor intensity of installation, but also means that the relative positions and angles between the keels are often fixed or can only be adjusted to a limited extent after connection. This limitation is particularly pronounced when fine-tuning of the keel positions is needed to adapt to actual site conditions, affecting the overall construction efficiency and accuracy. To overcome these shortcomings of existing technologies, this application proposes a self-locking universal connector for light steel keels. This connector cleverly combines a self-locking connection mechanism and a universal adjustment mechanism, achieving quick and convenient keel connection and multi-directional free adjustment of the keel position after connection, thereby greatly improving the installation efficiency and flexibility of light steel keel frames.

[0025] The self-locking universal connector for light steel keel disclosed in this application is mainly used to connect light steel keels, enabling convenient and quick installation and position adjustment. The connector includes a base 1, a socket 2, and a mounting base 3. The base 1 and socket 2 are the main components for installing the light steel keel, each with a mounting opening 4 on one side, allowing the light steel keel to be installed within the opening. The mounting base 3 is the intermediate component connecting the base 1 and socket 2; one side is connected to the base 1 via a universal connector, and the other side is connected to the socket 2 via a self-locking connector. The universal connector is a mechanism capable of multi-directional rotation and adjustment, while the self-locking connector is a mechanism that allows for quick connection and locking without additional fasteners.

[0026] Specifically, see Figures 1 to 5 The self-locking universal connector for light steel keel of this application includes a base 1, a socket 2, and a mounting base 3. Both the base 1 and the socket 2 are provided with mounting openings 4 for accommodating the light steel keel. The universal connector connects the base 1 and the mounting base 3, and includes a first connecting rod 5, a rotating seat 6, a rotating block 7, and a second connecting rod 8. The rotating seat 6 is provided with a ball groove 9. The first connecting rod 5 connects to the base 1, and the rotating seat 6 connects to the mounting base 3. The rotating block 7 is disposed within the ball groove 9, and the second connecting rod 8 connects the rotating block 7 and the first connecting rod 5. Through this universal connector, the mounting base 3 can achieve multi-directional rotation and angle adjustment relative to the base 1. For example, the first connecting rod 5 can be rotatably connected to the base 1 via a pin, the rotating seat 6 can be rotatably connected to the mounting base 3 via a pin, the second connecting rod 8 can be rotatably connected to the first connecting rod 5 via a pin, and the rotating block 7 can be fixedly connected to the second connecting rod 8. The cooperation between the ball groove 9 and the rotating block 7 allows the rotating block 7 to rotate freely within the ball groove 9, thereby achieving the universal adjustment function.

[0027] A self-locking connector connects the socket 2 and the mounting base 3. The self-locking connector includes a insertion groove 10, a socket 11, a gasket 12, a plug 13, a guide groove 14, an inclined surface 15, a snap-fit ​​portion 16, and a pressing portion 17. The insertion groove 10 and socket 11 are provided on the mounting base 3. The gasket 12, plug 13, inclined surface 15, snap-fit ​​portion 16, and pressing portion 17 are provided on the socket 2. The guide groove 14 is provided on the mounting base 3. The gasket 12 is inserted into the insertion groove 10. The plug 13 is guided by the guide groove 14 and engages with the inclined surface 15 to be inserted into the socket 11. The snap-fit ​​portion 16 prevents the plug 13 from disengaging from the socket 11, thus achieving a self-locking connection. The pressing portion 17 is used to press the gasket 12 to deform it when separation is required, thereby removing the plug 13 from the socket 11. For example, the gasket 12 can be made of a material with a certain degree of elasticity. The insert 13 is disposed on the gasket 12. When the gasket 12 is inserted into the insertion slot 10, the insert 13 enters the insertion hole 11 under the guidance of the guide slot 14 and the inclined surface 15. The undercut part 16 is locked at the edge of the insertion hole 11. Pressing the pressing part 17 can bend the gasket 12 inward, causing the insert 13 to disengage from the undercut part 16 of the insertion hole 11, thereby unlocking and separating.

[0028] Compared with existing technologies, the self-locking universal connector for light steel keel in this application has significant advantages. Existing connectors typically require additional bolts or screws for fastening, making the installation process cumbersome and time-consuming. This application, by incorporating a self-locking connector, achieves quick insertion and locking between the socket 2 and the mounting base 3 without any additional fasteners, greatly simplifying the installation operation and improving installation efficiency. Furthermore, existing connectors often only allow for limited adjustment or even complete fixation, making it difficult to precisely adjust the keel position during on-site installation. This application, by incorporating a universal connector, allows the mounting base 3 to rotate freely in multiple directions and adjust its angle relative to the base 1, thus allowing for flexible fine-tuning of the keel connected to the base 1 and socket 2. This solves the problem of insufficient adjustment freedom in existing technologies, improving construction flexibility and precision. Therefore, the dry-process decorative wall panel connector of this application is superior to existing technologies in terms of ease of installation, ease of operation, and flexibility of position adjustment.

[0029] When using the self-locking universal connector for light steel keel of this application, firstly, install the two light steel keels to be connected into the mounting openings 4 of the base 1 and the socket 2, respectively. Then, align the plug assembly on the socket 2 with the plug slot assembly on the mounting base 3, and push the socket 2 towards the mounting base 3. Specifically, insert the washer 12 on one side of the socket 2 into the plug slot 10 of the mounting base 3. At the same time, the plug 13 on the socket 2 will smoothly enter the socket hole 11 on the mounting base 3 under the guidance of the guide groove 14 of the mounting base 3 and the inclined surface 15 on the socket 2. Once the plug 13 is fully inserted into the socket hole 11, the buckle 16 on the plug 13 will lock into the edge of the socket hole 11, thereby preventing the plug 13 from accidentally disengaging and achieving a self-locking connection between the socket 2 and the mounting base 3. At this time, the two keels are connected together by the connector. If it is necessary to adjust the position or angle of the keel, it can be achieved through the universal connector. The universal connector connects the base 1 and the mounting base 3. When it is necessary to adjust the position of the mounting base 3 (and the socket 2 and keel connected to it) relative to the base 1 (and the keel connected to it), the base 1 or the mounting base 3 can be rotated. This rotation will drive the rotating block 7 to rotate within the ball groove 9 of the rotating seat 6 via the first connecting rod 5 and the second connecting rod 8, thereby achieving free adjustment of the mounting base 3 relative to the base 1 in multiple directions such as horizontal, vertical, and angular. This universal adjustment function makes it very convenient to fine-tune the position of the keel during on-site installation. When it is necessary to separate the socket 2 from the mounting base 3, simply press the pressing part 17 on the socket 2. The pressing part 17 will deform the gasket 12, causing the plug 13 to move out of the socket 11, thereby releasing the self-locking state and separating the socket 2 from the mounting base 3. During this connection process, the mounting holes 4 on the base 1 and the socket 2 are used to securely install the keel, ensuring the reliability of the connection. The first connecting rod 5, rotating seat 6, rotating block 7, second connecting rod 8, and ball groove 9 in the universal connector work together to provide multi-directional rotational freedom. The insertion slot 10, insertion hole 11, gasket 12, insertion block 13, guide groove 14, inclined surface 15, buckle part 16, and pressing part 17 in the self-locking connector together realize quick connection and separation without additional tools.

[0030] Furthermore, this application also proposes that the mounting opening is provided with mounting holes.

[0031] Specifically, see Figure 2Within the mounting openings 4 provided on the base 1 and the socket 2, mounting holes 18 are further provided. These mounting holes 18 communicate with the mounting openings 4 and are used to fix the light steel keel within the mounting openings 4. In a preferred embodiment, the mounting holes 18 can be designed to allow bolts to pass through for threaded connection with the light steel keel located within the mounting openings 4. The number and position of the mounting holes 18 can be configured as needed; for example, one or more mounting holes 18 can be provided on each of the opposite sidewalls of the mounting openings 4 to provide a more secure connection.

[0032] The mounting hole 18 provides a concrete way to reliably fix the light steel keel within the mounting opening 4 of the connector. By connecting the keel with bolts through the mounting hole 18, a strong mechanical connection can be formed, effectively preventing the keel from loosening or falling off within the mounting opening 4.

[0033] Therefore, by providing mounting holes 18 within the mounting opening 4, this application further provides a means for reliably fixing the keel to the connector, based on the original technical solution. This method of connecting with bolts through mounting holes 18 enhances the connection strength and stability between the keel and the connector, ensuring the overall structural safety and reliability of the keel frame, and is an effective supplement and optimization to the basic technical solution.

[0034] Furthermore, this application also proposes that a ball groove is provided on one side of the rotating seat, the rotating block is spherical, and the rotating block is adapted to the ball groove.

[0035] Specifically, see Figure 5 In the universal joint, a ball groove 9 is provided on one side of the rotating seat 6. The ball groove 9 is configured to accommodate and fit a spherical rotating block 7. The rotating block 7 is formed in the shape of a sphere or a near-sphere. The ball groove 9 and the spherical rotating block 7 are designed to fit together so that the rotating block 7 can rotate freely in multiple directions within the ball groove 9.

[0036] The ball groove 9 and the spherical rotating block 7 are the core structures that enable the universal joint to achieve multi-directional adjustment. The ball groove 9 provides a smooth inner surface that can accommodate the sphere, while the spherical rotating block 7 provides a contact surface that can roll freely on this inner surface. This ball-and-socket joint structure allows the second connecting rod 8 connected to the rotating block 7 to rotate at any angle around the center of the sphere relative to the rotating seat 6 with the ball groove 9.

[0037] Therefore, by specifying that the rotating seat 6 is provided with a ball groove 9 and that the rotating block 7 is spherical and adapted to the ball groove 9, this application further defines the key structural details for realizing the universal adjustment function based on the original universal connector assembly. This rotational engagement of the spherical rotating block 7 within the ball groove 9 provides greater rotational freedom than a simple hinge connection, enabling the mounting seat 3 to be adjusted horizontally, vertically, and at any angle relative to the base 1. This greatly improves the flexibility and range of position adjustment of the connector, representing a significant technological contribution to achieving multi-directional fine-tuning of the keel.

[0038] Furthermore, this application also proposes that the plug slot assembly includes a plug slot disposed on one side of the mounting base and two insertion holes disposed on the inner walls of the plug slot on both sides for connecting to the plug connector assembly, the insertion holes extending from the plug slot to the outer side of the mounting base.

[0039] Specifically, see Figure 4 A plug-in slot assembly is provided on one side of the mounting base 3. This plug-in slot assembly is part of a self-locking connector and is used to mate with the plug assembly on the socket 2 to achieve a connection. The plug-in slot assembly includes a plug slot 10 and two sockets 11. The plug slot 10 is formed into an open slot and is located on one side of the mounting base 3. The two sockets 11 are respectively located on the inner walls on both sides of the plug slot 10 and extend from the inside of the plug slot 10 to the outside of the mounting base 3. The plug slot 10 and the sockets 11 are configured to accommodate and adapt to the plug assembly on the socket 2, thereby achieving a plug-in connection.

[0040] The socket 10 provides an insertion channel for guiding the connector assembly on the socket 2 into place. The socket 11 is a structure for receiving and locking the plug 13 on the connector assembly. The design of the socket 11 extending outward from the inner wall of the socket 10 provides the necessary space and structure for the insertion and locking of the plug 13. The shape and size of the socket 10 and the socket 11 are designed to precisely mate with the gasket 12 and the plug 13 on the connector assembly to ensure a smooth and reliable connection.

[0041] Therefore, by clarifying the specific structure of the plug slot assembly in the self-locking connector, namely the plug slot 10 and socket 11 provided on the mounting base 3, this application further refines the basic physical interface of the self-locking connection function based on the original technical solution. The setting of the plug slot 10 and socket 11 provides a precise alignment and insertion structure for the plug assembly on the socket 2, which is an important component for realizing the self-locking connection function quickly and without additional fasteners, and provides a prerequisite for the subsequent locking mechanism.

[0042] Furthermore, this application also proposes that the connector assembly includes two gaskets disposed on one side of the socket and two plugs respectively disposed on the corresponding gaskets, the plugs being adapted to the socket for inserting the plugs into the socket.

[0043] Specifically, see Figure 3 A connector assembly is provided on one side of the socket 2. This connector assembly is another part of the self-locking connector and is used to mate with the plug slot assembly on the mounting base 3 to achieve connection. The connector assembly includes two washers 12 and two plugs 13. The two washers 12 are provided on one side of the socket 2 and are configured to be inserted into the plug slot 10 of the mounting base 3. The two plugs 13 are respectively provided on the corresponding washers 12 and are configured to be adapted to the sockets 11 on the mounting base 3 so as to be inserted into the sockets 11 during the connection process.

[0044] The gasket 12 is the main structure inserted into the insertion slot 10, providing support and positioning for the plug 13. The plug 13 is a key component for achieving the self-locking function; it is inserted into the socket 11 and structurally engages with the socket 11 to achieve a locking connection between the socket 2 and the mounting base 3. The shape, size, and relative position of the gasket 12 and the plug 13 are designed to precisely match the insertion slot 10 and the socket 11 to ensure smooth insertion and reliable connection. In a preferred embodiment, the gasket 12 can be made of a material with a certain degree of elasticity, allowing it to deform under the pressure of the pressing part 17, thereby achieving the unlocking function.

[0045] Therefore, by clarifying the specific structure of the plug assembly in the self-locking connector, namely the gasket 12 and plug 13 disposed on the socket 2, this application further refines another basic physical interface for the self-locking connection function based on the original technical solution. The gasket 12 and plug 13, together with the plug groove 10 and socket 11 on the mounting base 3, constitute the core structure for realizing the self-locking connection function quickly without additional fasteners, and are the direct execution components for realizing connection and locking.

[0046] Furthermore, this application also proposes that guide grooves are provided on the inner walls of both sides of the insertion slot. The guide grooves are adapted to the insertion block and are used to guide the insertion block into the insertion hole. The guide grooves extend from one side of the insertion hole to the outside of the insertion slot.

[0047] Specifically, see Figure 3 and Figure 4On the inner walls of both sides of the insertion slot 10 on the mounting base 3, guide grooves 14 are further provided. These guide grooves 14 are configured to fit the shape of the plug 13 on the socket 2, so as to guide the plug 13 during insertion. The guide groove 14 begins from one side of the socket 11 and extends outwards into the insertion slot 10. When the plug assembly on the socket 2 is pushed into the insertion slot 10 of the mounting base 3, the plug 13 first contacts the guide groove 14 and is guided along the direction of the guide groove 14, thus making it easier and more accurate to align and insert into the socket 11.

[0048] The main function of the guide groove 14 is to assist in the insertion process of the plug 13. Without the guide groove, the user may need to align the plug 13 and the socket 11 more precisely, increasing the difficulty of operation. By setting the guide groove 14, the plug 13 is automatically guided to the entrance of the socket 11 after entering the insertion slot 10, greatly improving the convenience and success rate of insertion. The shape of the guide groove 14 can match the side shape of the plug 13. For example, if the plug 13 has an inclined surface, the guide groove 14 can also be designed with a corresponding inclined structure to better guide the plug.

[0049] Therefore, by providing a guide groove 14 on the inner wall of the insertion slot 10 that matches the insertion block 13, this application further optimizes the insertion process of the self-locking connector based on the original technical solution. The design of the guide groove 14 allows the insertion block 13 to be effectively guided into the insertion hole 11, reducing alignment difficulty and improving the smoothness and reliability of the connection. This plays an important supporting role in achieving a fast and convenient self-locking connection function, further enhancing the user experience and installation efficiency of the connector.

[0050] Furthermore, this application also proposes that one side of the insert block is provided with an inclined surface for cooperating with the guide groove to guide the insert block.

[0051] Specifically, see Figure 3 On one side of the plug 13 on the socket 2, an inclined surface 15 is further provided. This inclined surface 15 is configured to mate with the guide groove 14 on the mounting base 3. When the plug 13 is guided along the guide groove 14, the inclined surface 15 contacts and slides against the inner wall of the guide groove 14, thereby further assisting the smooth insertion of the plug 13. The design of this inclined surface 15 makes it easier for the plug 13 to be guided and positioned before entering the socket 11.

[0052] The inclined surface 15 enhances the guiding effect of the guide groove 14. By providing the inclined surface 15 on the insert 13, the friction and jamming between the insert 13 and the guide groove 14 can be reduced, allowing the insert 13 to slide more smoothly along the guide groove 14 until it is aligned with the insertion hole 11. The angle and shape of the inclined surface 15 can be optimized according to the specific design of the insert 13 and the guide groove 14 to achieve the best guiding effect.

[0053] Therefore, by providing an inclined surface 15 on one side of the insert block 13 and having it cooperate with the guide groove 14, this application further optimizes the insertion process of the insert block 13 based on the original technical solution. The design of the inclined surface 15 makes the movement of the insert block 13 within the guide groove 14 smoother, improving the convenience and reliability of the insertion, and is another auxiliary technical feature for realizing the quick self-locking connection function.

[0054] Furthermore, this application also proposes that one side of the plug has an inverted part for limiting the plug after it is inserted into the socket.

[0055] Specifically, see Figure 3 On one side of the plug 13 on the socket 2, a retaining clip 16 is further provided. This retaining clip 16 is configured to engage or interfere with the edge or internal structure of the socket 11 after the plug 13 is fully inserted into the socket 11 of the mounting base 3. This engagement or interference effectively locks the plug 13 within the socket 11, preventing it from accidentally dislodging without external force, thus achieving a self-locking connection between the socket 2 and the mounting base 3.

[0056] The inverted locking part 16 is the key structure for achieving the self-locking function. It utilizes the elasticity of the material and a clever structural design to automatically lock into place after the insert 13 is inserted. The shape of the inverted locking part 16 can vary; for example, it can be a hook, a protrusion, or a bevel, as long as it can effectively limit movement within the insertion hole 11. The structure of the insertion hole 11 also needs to cooperate with the inverted locking part 16; for example, a corresponding slot or bevel can be provided at the entrance of the insertion hole 11.

[0057] Therefore, by providing a retaining clip 16 on the insert 13 and having it engage with the socket 11 to achieve a limiting position, this application further improves the self-locking connection function based on the original technical solution. The design of the retaining clip 16 ensures that the insert 13 can be reliably locked after being inserted into the socket 11, preventing accidental separation of the connector during use, thereby improving the stability and safety of the connection. This is one of the core technical features for achieving a self-locking connection without the need for additional fasteners.

[0058] Furthermore, this application also proposes that each of the two gaskets has a pressing part on one side for pressing the gasket to move the insert block out of the insertion hole, and the gasket is made of one piece of steel.

[0059] Specifically, see Figure 3 On one side of the two pads 12 on the socket 2, a pressing part 17 is further provided. This pressing part 17 is configured to facilitate pressing by the user; for example, it can be a protrusion, a groove, or a surface with an anti-slip texture. The function of this pressing part 17 is that when the self-locking connection needs to be released, the user can press the pressing part 17 to deform the pad 12, thereby causing the insert 13 provided on the pad 12 to move out of the socket hole 11 of the mounting base 3, releasing the locking state of the snap-lock part 16, and separating the socket 2 from the mounting base 3. As a preferred embodiment, the pad 12 can be integrally formed from steel to ensure sufficient strength and elasticity while simplifying the manufacturing process.

[0060] The pressing part 17 is an important operating interface for realizing the quick separation function of the self-locking connector. By setting the pressing part 17, the user can easily release the lock by simply pressing with their finger without the need for any tools, thus achieving quick disassembly of the connector. The gasket 12 is made of one-piece steel, which ensures that the gasket 12 can maintain its function and structural integrity even after repeated pressing and deformation, thereby improving the service life and reliability of the connector.

[0061] Therefore, by providing a pressing part 17 on the gasket 12 and using a one-piece steel molding process, this application further improves the separation function and structural strength of the self-locking connector based on the original technical solution. The design of the pressing part 17 makes the unlocking operation of the connector simple and convenient, improving the user experience. The material and molding method of the gasket 12 ensure the durability and reliability of the self-locking connector, which is an important technical feature for achieving quick and convenient connection and separation functions.

[0062] Furthermore, this application also proposes that both the base and the socket have two mounting holes, both of which are connected to the mounting opening, for passing bolts through which the keel is installed on one side of the base and the socket.

[0063] Specifically, see Figure 2 Two mounting holes 18 are further provided on the base 1 and the socket 2. Both mounting holes 18 communicate with corresponding mounting openings 4, meaning the opening of the mounting hole 18 is located on the inner wall of the mounting opening 4. The mounting hole 18 is configured to allow bolts to pass through. By placing the light steel keel inside the mounting opening 4, and then passing the bolt through the mounting hole 18 and screwing it into the threaded hole or nut provided on the keel, the keel can be securely fixed to one side of the base 1 or the socket 2.

[0064] The mounting holes 18 provide a concrete and reliable way to fix the light steel keel to the connector. The bolted connection creates a high-strength mechanical fixation, effectively preventing axial or radial movement of the keel within the mounting opening 4 and ensuring a stable connection. The design of two mounting holes 18 provides a more balanced stress distribution, further enhancing the reliability of the fixation.

[0065] Therefore, by providing two mounting holes 18 on both the base 1 and the socket 2, which communicate with the mounting port 4, and using them to install the keel with bolts, this application further clarifies the specific fixing method between the keel and the connector based on the original technical solution. This design, which uses bolts to pass through the mounting holes 18 for connection, provides a simple and effective fixing method, ensuring the stable installation of the keel within the connector, and is an important technical feature for improving the overall reliability of the connection.

[0066] 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.
