Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, and in particular to an adjustable steel structure connection device. Background Technology

[0002] In modern architecture, bridge engineering, and the manufacturing of large machinery and equipment, steel structures have become a widely used structural form due to their advantages such as high strength, good toughness, and short construction period. As a key component ensuring the stability and integrity of steel structures, the performance of steel structure connection devices directly affects the safety and quality of the steel structure. Therefore, research and innovation in steel structure connection devices have always been a focus of the industry.

[0003] Currently, common steel structure connection methods include bolting and welding. Bolting uses high-strength bolts to tightly fix steel structural components together, utilizing the friction generated by the bolt preload to transfer loads. Welding, on the other hand, uses high-temperature melting of welding rods or wires to achieve a metallurgical bond at the connection point, forming a robust joint. These traditional connection methods can meet the connection requirements of steel structures to a certain extent and play an important role in various engineering projects.

[0004] However, traditional connection devices typically use bolts or welding, both of which involve cumbersome installation procedures. Bolt connections require precise alignment and individual bolt tightening, demanding a certain level of skill from the operators and resulting in low installation efficiency. Welding, on the other hand, requires specialized welding equipment and personnel, necessitating surface cleaning and positioning preparations before welding. Furthermore, welding parameters must be controlled during the welding process to prevent defects. The entire installation process is time-consuming, making it difficult to meet the needs of projects with tight construction schedules. The complex procedures also increase construction costs and management difficulties. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable steel structure connection device, which aims to improve the problem that traditional connection devices usually use bolt connections or welding, both of which have cumbersome operation procedures during installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable steel structure connection device, comprising a mounting plate, wherein a connecting rod is rotatably connected to the inner wall of the mounting plate, and an adjustment component is provided on the inner wall of the connecting rod.

[0007] The adjusting assembly includes a plug rod, the outer wall of which is slidably connected to the inner wall of a connecting rod. A limiting disc is slidably connected to the outer wall of the plug rod. A second connecting rod is rotatably connected inside the limiting disc. A gear is fixedly connected to the outer wall of the second connecting rod. A fixing plate is fixedly connected to the outer wall of the mounting plate. A guide rail is fixedly connected to the inner wall of the fixing plate. A rack is slidably connected to the outer wall of the guide rail. A push rod is fixedly connected to the outer wall of the rack. The rack meshes with the gear.

[0008] Furthermore, a connecting plate is fixedly connected to the outer wall of the mounting plate, a connector is attached to the outer wall of the connecting plate, a fixing block is fixedly connected to the outer wall of the connector, and an installation component is provided on the inner wall of the connecting plate.

[0009] Furthermore, the installation assembly includes a locking block, the outer wall of which is slidably connected to the inner wall of the connecting plate, a connecting rod three is fixedly connected to the outer wall of the locking block, a sliding plate is fixedly connected to one end of the connecting rod three, a sliding block is fixedly connected to the outer wall of the sliding plate, a guide rod is fixedly connected to the outer wall of the sliding plate, a spring is sleeved on the outer wall of the guide rod, and a fixing rod is slidably connected to the inner wall of the guide rod.

[0010] Furthermore, the outer wall of the sliding plate is slidably connected to the inner wall of the fixed block, and the outer wall of the sliding block is slidably connected to the inner wall of the fixed block.

[0011] Furthermore, one end of the spring is fixedly connected to the inner wall of the fixed block, and the other end of the spring is fixedly connected to one side of the outer wall of the sliding plate.

[0012] Furthermore, one end of the fixing rod is fixedly connected to the inner wall of the fixing block, and the outer wall of the locking block is slidably connected to the inner wall of the connector.

[0013] Furthermore, the outer wall of the limiting disc is fixedly connected to the inner wall of the connector, and the fixing plate is fixedly connected to the outer wall of the connecting plate.

[0014] Furthermore, the mounting plate is attached to the outer wall of the connector.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, during installation, it is only necessary to pull the sliding block to compress the spring. After the parts fit together, release the spring, and the spring force will push the locking block to automatically engage, which simplifies the installation process, eliminates the need for complicated tools and cumbersome operations, and significantly improves installation efficiency. At the same time, the connection method in which the locking block penetrates deep into the connecting plate and the connecting parts enhances the stability and reliability of the connection and ensures the firmness of the steel structure connection.

[0017] 2. In this utility model, the angle of the connecting rod is flexibly adjusted by the meshing transmission of the rack and gear driven by the push rod. The user can push the push rod as needed, causing the rack to slide along the guide rail, thereby driving the gear to rotate and precisely adjusting the connecting rod to the required angle to meet the angle requirements under different working conditions. Furthermore, when the angle is adjusted to the correct position, the fixing method of the insert rod into the limiting plate and the connecting rod can firmly lock the connecting rod, ensuring that the angle is stable during use and will not shift, effectively improving the practicality and applicability of the steel structure connecting device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5An embodiment of this utility model is provided: an adjustable steel structure connection device, including a mounting plate 2, the mounting plate 2 provides a mounting base for components such as sliding block 20 and spring 17, a connecting rod 3 is rotatably connected to the inner wall of the mounting plate 2, and an adjustment component is provided on the inner wall of the connecting rod 3;

[0027] The adjustment assembly includes a rod 11. After adjustment to the target angle, the rod 11 is inserted into the corresponding hole of the limiting plate 10 and the connecting rod 3. Mechanical interlocking prevents rotation. The outer wall of the rod 11 is slidably connected to the inner wall of the connecting rod 3. The outer wall of the rod 11 is slidably connected to the limiting plate 10. The limiting plate 10 is rotatably connected to the connecting rod 9. The outer wall of the connecting rod 9 is fixedly connected to the gear 8. The rotation of the gear 8 is transmitted to the connecting rod 3 through the connecting rod 9 to achieve angle adjustment. The outer wall of the mounting plate 2 is fixedly connected to the fixing plate 4. The inner wall of the fixing plate 4 is fixedly connected to the guide rail 5, which provides a high-precision sliding track for the rack 6 to ensure smooth transmission. The outer wall of the guide rail 5 is slidably connected to the rack 6. The outer wall of the rack 6 is fixedly connected to the push rod 7. The rack 6 meshes with the gear 8. The outer wall of the limiting plate 10 is fixedly connected to the inner wall of the connecting piece 1. The fixing plate 4 is fixedly connected to the outer wall of the connecting plate 12. The mounting plate 2 is attached to the outer wall of the connecting piece 1.

[0028] Specifically, the mounting plate 2 is securely connected to the connector 1. The mounting plate 2 has a groove structure adapted to the sliding block 20, allowing the sliding block 20 to slide flexibly within the groove. A spring 17 is connected to its side, and the other end of the spring 17 is fixed at a specific position inside the mounting plate 2, forming an elastic connection mechanism. During installation, the operator manually pulls the sliding block 20, causing it to move along the groove, thereby compressing the spring 17. Simultaneously, the sliding block 20 is connected to the locking block 14 via the connecting rod 15. When the sliding block 20 moves, it drives the connecting rod 15 to move together. The step is moved, causing the locking block 14 to disengage from its initial position. At this point, the connecting plate 12 is placed against the inner wall of the connector 1, ensuring that the two are accurately aligned. Subsequently, the operator releases the sliding block 20, and the compressed spring 17 releases its stored elastic potential energy. The resulting elastic force pushes the sliding block 20 back to its original position, thereby causing the connecting rod 15 to move together with the locking block 14, so that the locking block 14 is precisely engaged in the pre-set slots of the connecting plate 12 and the connector 1, completing the tight installation of the connecting plate 12 and the connector 1. This structural design makes the installation process both simple and reliable, effectively ensuring the stability of the connection.

[0029] Reference Figures 1-5A connecting plate 12 is fixedly connected to the outer wall of the mounting plate 2. A connector 1 is attached to the outer wall of the connecting plate 12. A fixing block 13 is fixedly connected to the outer wall of the connector 1. An installation assembly, including a locking block 14, is provided on the inner wall of the connecting plate 12. The outer wall of the locking block 14 is slidably connected to the inner wall of the connecting plate 12. A connecting rod 15 is fixedly connected to the outer wall of the locking block 14. A sliding plate 16 is fixedly connected to one end of the connecting rod 15. A sliding block 20 is fixedly connected to the outer wall of the sliding plate 16. Quick assembly and disassembly with the connector 1 are achieved through the elastic locking of the sliding block 20. A guide is fixedly connected to the outer wall of the sliding plate 16. Rod 19 ensures the linear movement trajectory of sliding plate 16 and sliding block 20, prevents deflection, and improves operational stability. Spring 17 is sleeved on the outer wall of guide rod 19. Fixed rod 18 is slidably connected to the inner wall of guide rod 19. The outer wall of sliding plate 16 is slidably connected to the inner wall of fixed block 13. The outer wall of sliding block 20 is slidably connected to the inner wall of fixed block 13. One end of spring 17 is fixedly connected to the inner wall of fixed block 13. The other end of spring 17 is fixedly connected to one side of the outer wall of sliding plate 16. One end of fixed rod 18 is fixedly connected to the inner wall of fixed block 13. The outer wall of locking block 14 is slidably connected to the inner wall of connector 1.

[0030] Specifically, when the angle of connecting rod 3 needs to be adjusted, the unique design of this device enables precise and convenient operation. In the device, the guide rail 5 is fixedly mounted on a specific base, its outer wall is smooth and has a guide groove. The rack 6 is tightly fitted against the outer wall of the guide rail 5 and can slide stably along the guide groove. The push rod 7 is fixedly connected to the rack 6. By pushing the push rod 7, the operator can drive the rack 6 to slide linearly along the outer wall of the guide rail 5. Since the rack 6 and gear 8 are meshed, when the rack 6 slides, its teeth interact with the teeth of the gear 8, causing the gear 8 to rotate. The gear 8 is connected to the connecting rod 3 via a rotating shaft. Since the connecting rod 2 is connected to 9, the rotation of the gear 8 will be transmitted to the connecting rod 2, which in turn will drive the connecting rod 1 3, which is hinged to the connecting rod 2, to rotate. This allows for flexible adjustment of the angle of the connecting rod 1 3. When the connecting rod 1 3 rotates to a suitable position that meets the actual needs, the limiting plate 10 has multiple limiting holes that are compatible with the insert rod 11, and the connecting rod 1 3 also has a corresponding insertion hole. At this time, inserting the insert rod 11 into the insertion hole of the limiting plate 10 and the connecting rod 1 3 will firmly fix the connecting rod 1 3, preventing it from shifting its angle during subsequent use and ensuring that the entire steel structure connection device works stably at a specific angle.

[0031] Working principle: When the adjustable steel structure connection device is required, the mounting plate 2 and the connector 1 need to be connected together for installation. Pulling the sliding block 20 compresses the spring 17. The sliding block 20 drives the connecting rod 15 and the locking block 14 to move. Then, the connecting plate 12 and the inner wall of the connector 1 are pressed together. At this time, the sliding block 20 is released, the spring 17 releases its elastic force, and pushes the connecting rod 15 and the locking block 14 to be inserted into the connecting plate 12 and the connector 1, thus realizing the installation of the connecting plate 12 and the connector 1.

[0032] Furthermore, when it is necessary to adjust the angle of connecting rod 3, push the push rod 7 to drive the rack 6 to slide along the outer wall of the guide rail 5. Because the rack 6 and the gear 8 are meshed, the rack 6 will drive the gear 8 to rotate while sliding, which in turn will drive the connecting rod 9 and connecting rod 3 to rotate, thereby achieving the effect of adjusting the angle of connecting rod 3. When the connecting rod 3 rotates to the appropriate position, insert the insert rod 11 into the limiting plate 10 and the connecting rod 3 to fix the connecting rod 3.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
