Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to a steel structure connection anti-detachment self-locking component. Background Art

[0002] In the fields of construction and engineering, especially in applications using steel structures, the importance of connection technology is self-evident. Traditional steel structure connection methods mostly rely on welding, bolting or other traditional fixing methods. However, these traditional methods often have many limitations, such as complex installation, high maintenance costs, sensitivity to stress concentration, and difficulty in quick disassembly. For example, although welding can provide a stable connection, it does not have the adjustability and flexibility of disassembly, and is prone to fatigue cracks in high-stress environments. Although bolted connections can be disassembled and adjusted in some cases, they usually need to be regularly inspected and tightened to prevent loosening and failure. These problems are particularly prominent in environments with frequent vibrations or load changes.

[0003] In addition, as modern architecture and engineering design develop towards a more efficient and flexible direction, the requirements for connection technology are also increasing. Especially in modular buildings and fast-assembly structures, traditional steel structure connection methods often face many challenges, such as connection reliability, maintenance costs, construction efficiency, and dealing with fatigue and loosening problems in long-term use.

[0007] Preferably, a first connecting plate is fixedly connected to one side of the outer wall of the second connecting member, a second connecting plate is fixedly connected to one side of the outer wall of the third connecting member, a first connecting member is provided on the outer wall of the second connecting member, a first side plate is fixedly connected to the upper surface of the second connecting plate, and a fixing plate is fixedly connected to the upper surface of the first side plate.

[0008] Preferably, the lower surface of the first connecting plate is fixedly connected with a fixing piece, the lower surface of the fixing piece is fixedly connected with the second side plate, one side of the outer wall of the second side plate is fixedly connected with a limiting block, the lower surface of the limiting block is fixedly connected with a first pressing block, and the outer wall of the limiting block is fixedly connected with a second clamping block.

[0009] Preferably, a mounting groove is provided inside the fixing plate, a limit spring is fixedly connected inside the mounting groove, one end of the limit spring is fixedly connected to a circular plate, and the lower surface of the first pressing block fits with the lower surface of the circular plate.

[0010] Preferably, a fixing plate is fixedly connected to the interior of the first side plate, and a mounting plate is fixedly connected to one side of the outer wall of the fixing plate.

[0011] Preferably, a movable groove is provided inside the mounting plate and the first side plate, and a first movable block is slidably connected inside the movable groove.

[0012] Preferably, a connecting rod is fixedly connected to one side of the outer wall of the first movable block, one end of the connecting rod is rotatably connected to a cross bar, the inside of the cross bar is rotatably connected to a rotating rod, the outer wall of the rotating rod is rotatably connected to the first clamping block, and the inner wall of the first clamping block is in contact with the outer wall of the second clamping block.

[0014] Preferably, threaded holes are provided inside the second side plate, the limiting block and the third connecting member, and screws are connected to the internal threads of the threaded holes.

[0015] Working principle: The first connector and the second connector need to be connected together. The threaded rod does not rotate, and the distance between the second pressing block and the fixed ring and the plug block is large. The first clamping block and the second clamping block are separated, and the staff rotates the threaded rod to stretch it, compressing the second spring to move the second pressing block downward. The movement of the second pressing block will cause the distance between the fixed ring and the plug block to decrease, and the plug block will move upward, pushing the rotating ring to rotate. The rotation of the rotating ring will enhance the meshing between the built-in gear and the rotating gear, increasing the firmness of the connection. Once the connection is completed, the upper end of the threaded rod is fixedly connected to the fixed ring and no longer rotates. The force of the second spring will maintain the downward position of the second pressing block and maintain the connection state. At the same time, the first clamping block and the second clamping block fit each other, increasing the stability of the connection. Even if it is subjected to external vibration or impact, the connector is not easy to loosen, achieving the effect of self-locking and anti-slipping. To release the connection, the user only needs to rotate the threaded rod in a counterclockwise direction to reduce the length of the threaded rod. This will reduce the downward pressure of the second pressing block, causing the second spring to push the plug block and the rotating ring to rotate, weakening the meshing between the built-in gear and the rotating gear. Finally, the connector can be easily separated.

[0016] The present invention provides a steel structure connection anti-detachment self-locking component. It has the following beneficial effects:

[0017] 1. In the present invention, when the threaded rod stretches and compresses the second spring, the second pressing block moves downward, which can cause the connecting piece to be locked. This self-locking function increases the convenience and safety of operation and reduces the potential risks caused by loose connection.

[0018] 2. Due to the reliability of the self-locking function and the durable design of the components of the present invention, the maintenance requirements of the device are relatively low, and the long-term stable connection reduces the need for frequent inspection and tightening of the connectors, thereby reducing maintenance costs.

[0019] 3. The present invention achieves this through the cooperation between the above structures. The design can reduce material fatigue. Its self-locking mechanism ensures a continuous and stable connection, reducing fatigue problems caused by stress concentration or loosening. At the same time, for modular or prefabricated buildings, the quick connection and disassembly function of the component can significantly improve construction speed and flexibility.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example:

[0032] Please refer to the attached Figure 1 - Attachment Fig. 9The embodiment of the present invention provides a steel structure connection anti-slip self-locking component, including a second connecting member 2, a third connecting member 3 is arranged on the lower surface of the second connecting member 2, a fixing groove 19 is provided inside the second connecting member 2, a connecting mechanism is arranged inside the third connecting member 3, and the connecting mechanism includes a rotating ring 20, a first limiting ring 21 is fixedly connected to the upper surface of the rotating ring 20, a built-in gear 22 is provided inside the first limiting ring 21, a second limiting ring 32 is arranged on the upper surface of the built-in gear 22, an insert block 31 is fixedly connected to the inside of the second limiting ring 32, a groove is provided inside the insert block 31, a fixed shaft 28 is fixedly connected to the inside of the insert block 31, a second spring 30 is fixedly connected to the outer wall of the fixed shaft 28, one end of the second spring 30 is fixedly connected to the third clamping block 29, a second moving block 27 is fixedly connected to the lower surface of the third clamping block 29, a second moving block 27 is slidably connected to the lower surface of the second pressing block 26, and a rotating component is fixedly connected to the lower surface of the second pressing block 26.

[0033] In one embodiment, the second connecting member 2 is connected to one of the steel structure components and ensures that the groove on its lower surface is aligned with the connecting mechanism of the third connecting member 3. The third connecting member 3 is inserted into the groove of the second connecting member 2, and the connecting mechanism is started. By rotating the rotating ring 20, the built-in gear 22 is embedded in the corresponding gear to increase the stability of the connection. The fixed connection between the groove of the plug block 31 and the lower surface of the second pressing block 26 ensures an anti-slip self-locking effect. The presence of the spring 30 provides a certain flexibility to adapt to changes under load.

[0034] Specifically, the design of the component ensures the firmness of the connection and prevents accidental detachment of the steel structure components under vibration or load. By adjusting the rotating ring 20, the tightness of the connection can be adjusted as needed to adapt to different application scenarios. The design of the multi-layer connection mechanism improves the stability and safety of the connection and reduces the risk of accidents. The multiple parts and complex structures of the component may have a long service life and high durability.

[0035] The rotating assembly includes a fixing ring 25, the upper surface of the fixing ring 25 is fixedly connected to the lower surface of the plug block 31, the lower surface of the second pressing block 26 is fixedly connected to the threaded rod 24, the outer wall of the threaded rod 24 is fixedly connected to the rotating gear 23, the rotating gear 23 is meshed with the built-in gear 22, and the lower surface of the second pressing block 26 is fixedly connected to the upper end of the threaded rod 24.

[0036] In one embodiment, when you apply force or torque to the rotating gear 23, the threaded rod 24 will be subjected to the effect of rotation. Since there are threads on the threaded rod, the rotating gear 23 will cause the threaded rod 24 to rotate. Since the lower surface of the second pressing block 26 is fixedly connected to the upper end of the threaded rod 24, when the threaded rod rotates, the second pressing block will also rotate. The plug block 31 is connected to the fixing ring 25, so the fixing ring will also rotate with the second pressing block. The built-in gear 22 is meshed with the rotating gear 23, so when the rotating gear rotates, it will transmit power to the built-in gear, thereby realizing the rotation of the built-in gear.

[0037] Specifically, through the linkage of the threaded rod 24, the rotating gear 23 and the built-in gear 22, it can effectively transmit the input rotational motion to other components or systems to achieve certain mechanical functions. The connection design of the fixing ring 25 and the second pressing block 26 is stable to prevent them from accidentally separating or loosening during operation. It has certain adjustment performance and the rotation speed or direction of the rotating gear 23 can be controlled by rotating the threaded rod 24.

[0038] A first connecting plate 4 is fixedly connected to one side of the outer wall of the second connecting member 2, a second connecting plate 5 is fixedly connected to one side of the outer wall of the third connecting member 3, a first connecting member 1 is provided on the outer wall of the second connecting member 2, a first side plate 6 is fixedly connected to the upper surface of the second connecting plate 5, and a fixing plate 7 is fixedly connected to the upper surface of the first side plate 6.

[0039] In one embodiment, this connector provides strong structural support and connection, thereby ensuring that the connected components will not loosen or move during use, increasing the reliability and stability of the system. By connecting the first connector 1 to the second connector 2 and then connecting the third connector 3 to the second connector 2, a multi-layer connection structure can be achieved.

[0040] The lower surface of the first connecting plate 4 is fixedly connected with a fixing piece 14, the lower surface of the fixing piece 14 is fixedly connected with a second side plate 15, one side of the outer wall of the second side plate 15 is fixedly connected with a limiting block 18, the lower surface of the limiting block 18 is fixedly connected with a first pressing block 17, and the outer wall of the limiting block 18 is fixedly connected with a second clamping block 16.

[0041] In one embodiment, by connecting the fixing member 14 and the second side panel 15, the stability of the device is enhanced, and it can better withstand external forces and vibrations. This design ensures the stability and reliability of the connection, and it is not easy to loosen or detach even under load and stress. The fixed connection between these components makes it suitable for modular buildings and engineering, and can be quickly assembled and disassembled, thereby improving construction efficiency.

[0042] A mounting groove is provided inside the fixing plate 7, a limit spring is fixedly connected inside the mounting groove, one end of the limit spring is fixedly connected to a circular plate, and the lower surface of the first pressing block 17 fits with the lower surface of the circular plate.

[0043] In one embodiment, when the connector needs to be kept in a tight state, the limit spring applies force within the limit elastic range to push the circular plate toward the first pressing block 17, and the pressure of the circular plate is transmitted to the first pressing block 17, so that it fits with the circular plate. This fitting process ensures the tight state of the connector, and the elastic characteristics of the limit spring allow the tightness of the connection to be fine-tuned when necessary to adapt to different application scenarios. When the connection needs to be released, the user can rotate the threaded rod 24 counterclockwise to reduce the length of the threaded rod 24. This will reduce the force applied by the limit spring, so that the connector can be easily separated.

[0044] A fixing plate 7 is fixedly connected to the interior of the first side plate 6 , and a mounting plate 8 is fixedly connected to one side of an outer wall of the fixing plate 7 .

[0045] In one embodiment, the connection between the first side plate 6 and the fixing plate 7 enhances the stability of the overall structure. This is very important for applications that are subject to loads and stresses, and the connection of the fixing plate 7 to the mounting plate 8 provides additional support and stability, especially when a larger support area is required, which can reduce stress concentration.

[0046] Both the mounting plate 8 and the first side plate 6 are provided with movable grooves, and the first movable blocks 9 are slidably connected to the movable grooves.

[0047] In one embodiment, the provision of the movable groove and the first movable block 9 allows the relative position of the connection parts to be fine-tuned when necessary. This is very useful for meeting different application scenarios and requirements. This design is very suitable for modular construction and engineering because it allows position adjustment during assembly and disassembly while maintaining a firm connection. Adjustability and position flexibility reduce the difficulty of maintaining the connection because it can be easily adjusted and adapted to changing conditions. The presence of the movable groove and the first movable block 9 can help alleviate stress concentration and increase the stability of the connection.

[0048] A connecting rod 10 is fixedly connected to one side of the outer wall of the first movable block 9, one end of the connecting rod 10 is rotatably connected to a cross bar, the interior of the cross bar is rotatably connected to a rotating rod 11, the outer wall of the rotating rod 11 is rotatably connected to a first clamping block 12, and the inner wall of the first clamping block 12 is in contact with the outer wall of the second clamping block 16.

[0049] In one embodiment, this structure allows the relative position between the connecting rod 10 and the first movable block 9 to be controlled by rotating the cross bar, thereby adjusting the shape and size of the connection. Through the connection of the cross bar, the rotating rod 11 and the first clamping block 12, the rotational force can be effectively transmitted to the connecting parts to ensure the firmness of the connection. The fit between the first clamping block 12 and the second clamping block 16 ensures the stability of the connection, and it is not easy to loosen even under external vibration or impact. This design reduces the number of parts that require maintenance because their connection is relatively simple and reliable.

[0050] A first spring 13 is fixedly connected to one side of the outer wall of the mounting plate 8 , and one end of the first spring 13 is fixedly connected to one side of the outer wall of the first clamping block 12 .

[0051] In one embodiment, the presence of the first spring 13 increases the self-locking property. When the connecting parts are tightened, the spring will apply pressure to increase the stability and safety of the connection. The force of the spring keeps the first clamping block 12 in the connected state. Even in the case of external vibration or impact, the connection is not easy to loosen. This design reduces the need for frequent inspection and maintenance of the connection and reduces maintenance costs. The user can easily rotate the threaded rod to change the state of the connection, quickly connect and release the connection, and improve the convenience of operation.

[0052] The second side plate 15 , the limiting block 18 and the third connecting member 3 are all provided with threaded holes inside, and screws are threadedly connected inside the threaded holes.

[0053] In one embodiment, the screw connection method provides flexibility because the screws can be tightened or loosened as needed to meet different requirements and conditions. The threaded connection of the screws ensures the firmness of the connection, and the connection is not easy to loosen even under external vibration or impact. The screw connection method is relatively fast and easy, and is suitable for applications that require quick assembly.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
