[0002] Steel structures are developing rapidly in China with their characteristics of light weight, high strength, fast installation speed and short construction period. The installation of steel structures must not only meet the construction period requirements, but also the requirements of installation quality and accuracy. When connecting components, attention should be paid to the dimensions between components. It is necessary to ensure that the dimensional parameters between components meet the design requirements to ensure the structural safety and installation quality of the columns, so as to ensure that the connection between components is firm and reliable.

[0045] Embodiment 3:

[0046] See attached Figure 1 To Attachment Figure 6 In this embodiment, a driving switch 705 is added on the basis of the locking structure of the specific embodiment 2. A locking groove 701 is provided in the inner wall of the threaded hole 201 on the connecting body 200. The locking structure includes a sliding clamping block 702 slidably set in the locking groove 701, a telescopic spring 703 set between the bottom wall of the locking groove 701 and the sliding clamping block 702, and a driving switch 705 set on the connecting body 200. A partial thread 704 is provided at one end of the sliding clamping block 702 close to the threaded hole 201 of the connecting body 200. The partial thread 704 on the sliding clamping block 702 can be connected with the thread in the threaded hole 201 in the connecting body 200 to form a complete set of threads. The partial thread 704 of the sliding clamping block 702 can always be engaged with the external thread on the connecting screw 302 of the adjusting screw body 300 in the connecting body 200, and when the connecting screw 302 with the adjusting thread is locked by the sliding clamping block 702 containing the partial thread 704, the external thread of the connecting screw 302 will not be damaged, and the locking accuracy of the connecting body and the adjusting bolt 300 can also be improved.

[0047] The driving switch 705 is threadedly connected to the connecting body 200, and a portion of the driving switch 700 extends into the locking slot 701, and the end portion is rotationally connected to the sliding clamping block 702.

[0048] Example 4: See attached Figure 1 To Attachment Figure 4 A box-type column docking adjustable node includes a slot-type connector 100, one side of which is significantly higher than the middle part, the bottom surface is perpendicular to the side surface, and a plurality of bolts 102 are arranged through the surface of the bottom surface in the length direction, and a metal gasket 500 is arranged at the contact position between the bolts 102 and the surface. The A end of the slot-type connector 100 is a through-port or a connecting device body, and the B end is provided with an opening 101 recessed into the surface. The opening 101 and the outer edge of the B end are arranged to fit tightly with the connector 200, and the opening 101 forms a space to accommodate the passage of the connecting screw 302. Every two slot-type connectors 100 are fixedly connected to the connecting screw 302 through the space formed by the opening 101 and the connector 200, and the two connected connecting screws are fixedly connected by the bolt cap 301 sleeved thereon.

[0049] Due to the use of the metal gasket 500, the contact between the bolt and the connecting piece is more stable, thereby increasing the stability of the entire structure. In particular, this design can better ensure the reliability of the connection when facing vibration, temperature changes or long-term use. Through the space formed by the opening 101 and the connecting piece 200, the connecting screw 302 can be easily inserted and removed, greatly improving the assembly efficiency. At the same time, the addition of the bolt cap 301 further simplifies the fixing operation of the screw.

[0050] Each slot connector is independent and can be replaced or repaired individually. This modular design makes maintenance easier. Due to its flexible opening design, the connector can adapt to different specifications of connecting screws, making the connector have a wider range of applications. The metal gasket and bolt cap have good corrosion resistance, which can ensure that the connector can maintain its performance in various environments. Its compact design not only reduces space occupation, but also facilitates installation in small spaces. The overall structure and material selection take into account durability, allowing this connector to withstand long-term use.

[0051] The outer edge of the side wall of the groove-type connector 100 is evenly provided with side connectors 105, and the other side thereof near the width direction is evenly provided with main body connectors 104, and the height of the main body connectors 104 is higher than the side connectors 105. The nut 103 is sleeved outside the connection point between the bolt 102 and the bottom surface of the groove-type connector 100, and the pressure-bearing circular block 600 is laid at the contact position between the nut 103 and the bottom surface. The structure of the pressure-bearing circular block 600 specifically includes an integrated convex hollow structure, including a large-radius circular ring 2 602 and a small-radius circular ring 1 601, wherein the circular ring 2 and the circular ring 1 are an integrated structure, and their internal radii are equal, and the external radius of the circular ring 2 is larger than that of the circular ring 1.

[0052] By evenly laying the side connectors 105 on the outer edge of the side wall and evenly setting the main connector 104 near the other side in the width direction, the stability of the entire connector is significantly improved. This design can better withstand external loads and reduce the possibility of deformation or displacement of the connector. The setting of the nut 103 makes the connection between the bolt and the grooved connector more secure, and is also conducive to adjusting the tightness of the bolt. The design of the pressure-bearing round block 600 at the contact position between the nut and the bottom surface further enhances the stability of the bolt and the connector and reduces the risk of the bolt loosening or falling off.

[0053] The integrated convex hollow structure makes the pressure bearing round block 600 easier to manufacture and reduces the production cost. This design also reduces the friction between the various components and improves the smoothness and service life of the connector. The height of the main connector 104 is higher than the side connector 105, which improves the overall load-bearing capacity of the connector. This design is particularly suitable for mechanical devices or structures that need to bear large loads.

[0054] The improved design reduces stress concentration points and improves the fatigue resistance of the connector. This allows the connector to maintain its performance during long-term use and reduces the frequency of maintenance and replacement. The overall compact design not only reduces the size of the connector itself, but also facilitates efficient assembly in a limited space. This is particularly important for applications with limited space. The matching design of the nut 103 and the pressure-bearing round block 600 effectively prevents the bolt from loosening and ensures the reliability of the connection.

[0055] In addition, the slotted connector 100 is embedded in the connector 200 at the slot, and a threaded hole 201 is hollowed out in the surface of the connector 200. This improved design further enhances the functionality and practicality of the slotted connector. By embedding the connector at the slot and providing a threaded hole on the connector, the connection between the connector and the connector is more secure and can withstand greater external loads. The hollow threaded hole design eliminates the need for additional processing of the connector during installation, simplifies the installation process, and improves work efficiency.

[0056] The tight fit between the connector and the grooved connector makes the overall structure more compact and reduces problems caused by loose connections. Due to the design of the connector and the connector, when a connector needs to be repaired or replaced, it can be easily operated without affecting the stability of the overall structure. The design of the threaded hole and the fit of the bolt effectively prevent the connector from loosening and ensure long-term stability.

[0057] Embodiment 5: As attached Figure 5 As shown, a box-type column docking adjustable node has a locking structure in which a locking groove 701 is arranged in the direction perpendicular to the threaded hole on the connector 200, and a telescopic spring 703 is arranged in contact with the end of the locking groove 701. One end of the telescopic spring 703 is tightly against the locking groove 701, and the other end is tightly connected to the sliding clamping block 702. A partial thread 704 is also arranged at the other end of the sliding clamping block. This improved design introduces a unique locking structure in the groove-type connector. The design of the locking groove 701 is combined with the telescopic spring 703 and the sliding clamping block 702 to provide an adaptive locking mechanism. This mechanism can automatically adjust its locking force as the external load changes to ensure that the connector always remains tightly connected.

[0058] Compared with the traditional bolt and nut connection, this locking structure can achieve quick locking or loosening without the use of additional tools, which greatly simplifies the operation process. Due to its quick locking feature, this structure is particularly suitable for scenarios that require quick assembly or maintenance, significantly improving work efficiency. The tight connection between the telescopic spring 703 and the sliding clamping block 702 ensures the anti-loosening performance of the connector. Even in the case of long-term use or vibration, this structure can effectively prevent the connector from loosening. Due to its adaptive locking mechanism, this structure can adapt to a variety of external loads and connection requirements and has high adaptability.

[0059] The unique material and structural design make this locking structure have a long service life and reduce the frequency of maintenance and replacement. Due to its simple structure and excellent performance, the maintenance cost of this locking structure is relatively low, which helps to reduce long-term operating costs. In summary, this improved design of the grooved connector improves the stability, working efficiency, anti-loosening performance, adaptability and durability of the connector by introducing a unique locking structure, simplifies the operation process and reduces maintenance costs. This design has broad application prospects and advantages in various mechanical and structural applications.

[0060] Embodiment 6: As attached Figure 6As shown, a box-type column docking adjustable node, whose locking structure is arranged on the connecting body 200 in the direction of the vertical threaded hole, and the end of the locking slot 701 is connected with the connecting body 200, and a through hole is provided to pass the driving switch 705. The driving switch 705 is provided with a telescopic spring 703 in contact with the end of the locking slot 701, one end of the telescopic spring 703 is tightly against the locking slot 701, and the other end is tightly connected with the sliding clamping block 702. The driving switch 705 passes through the internal gap of the telescopic spring 703 and is in close contact with one end of the sliding clamping block 702. The other end of the sliding clamping block is also provided with a partial thread 704.

[0061] The combination of the locking slot 701, the telescopic spring 703 and the sliding clamping block 702 provides an adaptive locking mechanism. This mechanism can automatically adjust its locking force as the external load changes to ensure that the connector always remains tightly connected. By introducing the drive switch 705, the user can remotely or automatically control the opening and closing of the locking structure. This greatly simplifies the operating process and reduces the need for manual operation. Due to the setting of the drive switch, the user can operate at a distance from the connector. This is very useful in certain specific applications, such as working at height or in a small space.

[0062] Through remote control, users can avoid direct contact with the connector, thus reducing safety risks during operation. The design of the drive switch allows the locking structure of the connector to be integrated with various automation systems. This enables the connector to adapt to the requirements of modern factories and automated production lines. Combined with the design of the telescopic spring and the sliding clamping block, the locking structure has excellent anti-loosening performance. This structure can effectively prevent the connector from loosening even under long-term use or vibration. The unique material and structural design make this locking structure have a long service life and reliability. This helps to reduce the frequency of maintenance and replacement and reduce long-term operating costs.

[0063] Embodiment 7: A box-type column docking adjustable node, with a locking structure technically expanded, and the rest is the same as other embodiments.

[0064] Solution 1: Introduce sensors and microcontrollers to achieve real-time monitoring and automatic adjustment of the locking structure. For example, when insufficient locking force is detected, the microcontroller can automatically adjust the drive switch. In the locking structure of the slotted connector, add a pressure sensor and a microcontroller. The pressure sensor is used to detect the locking force, and the microcontroller makes real-time adjustments based on the sensor signal. For example, when insufficient locking force is detected, the microcontroller can automatically adjust the drive switch to increase the locking force. This technical expansion can ensure the stability and safety of engine connection components under various working conditions.

[0065] The benefit is that the introduction of sensors and microcontrollers can monitor the status of the locking structure in real time, and detect and solve potential problems in a timely manner. The microcontroller can automatically adjust the state of the locking structure based on the feedback from the sensor to ensure the stability and security of the connection.

[0066] Solution 2: Multiple locking methods, such as nuts and latches, can be integrated on one connector to meet different locking requirements and adapt to different application scenarios. Multiple locking methods, such as nuts and latches, are integrated on the slot connector. According to actual needs, select the appropriate locking method for connection. For example, nuts are used in areas that require high-strength locking, while latches are used in areas that require quick installation. This technical expansion can improve the stability and safety of building structures while meeting different locking requirements and adapting to different application scenarios.

[0067] The advantage is that the integration of multiple locking methods can meet different application requirements, making the connector more adaptable and flexible. Selecting the appropriate locking method according to actual needs can quickly complete the connection and improve work efficiency.

[0068] Solution 3: Integrate the locking structure with other functional modules, such as unlocking module, release module, etc., to achieve more functional integration and optimization. Integrate the locking structure of the slotted connector with the unlocking module, release module, etc. By integrating these functional modules, the flexible movement and rapid response of the robot arm can be achieved. For example, when the posture of the robot arm needs to be adjusted, it is unlocked through the unlocking module, and then the locking structure is adjusted through the drive switch, and finally fixed through the release module. This technical expansion can improve the operating efficiency and accuracy of the robot arm.

[0069] The benefit is that integrating the locking structure with other functional modules can optimize the entire system, reduce unnecessary components and lines, and reduce costs and maintenance difficulties. Integrating multiple functional modules can improve the stability and reliability of the entire system and reduce the possibility of failure.

[0070] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
