Description

Technical Field

[0001] This utility model relates to the field of flat steel technology, and in particular to a high-hardness tensile flat steel. Background Technology

[0002] In fields such as machinery manufacturing, construction engineering, shipbuilding, and military equipment, high-hardness tensile flat steel has become a core structural component for bearing high loads and high stress conditions due to its excellent mechanical properties (such as high strength, high hardness, good tensile strength and wear resistance). This type of flat steel needs to be spliced ​​and connected to form a complete force-bearing system according to actual construction or assembly requirements. Its connection efficiency and stability directly affect the overall project progress and structural safety.

[0003] Currently, the industry still primarily uses traditional bolt and nut fixing for connecting high-hardness tensile flat steel. However, this traditional connection method has significant drawbacks in practical applications: low installation and disassembly efficiency; the high hardness of high-hardness tensile flat steel makes drilling difficult and time-consuming; and the assembly of bolts and nuts requires aligning each hole individually and repeatedly tightening with tools such as wrenches. Furthermore, disassembly for subsequent maintenance or structural adjustments is time-consuming and labor-intensive, especially in large-scale flat steel splicing scenarios (such as large building steel structures and ship deck assembly), where the disassembly and assembly of numerous bolts severely slows down construction progress, leading to a significant reduction in the installation efficiency of workers.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When workers install or disassemble the flat steel body, the traditional fixing method is mostly bolt and nut fixing, which makes the installation or disassembly time-consuming and laborious, resulting in low installation efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is that in the existing technology, when workers install or disassemble the flat steel body, the traditional fixing method is mostly bolt and nut fixing, which makes the installation or disassembly time-consuming and laborious, resulting in low installation efficiency. To this end, we propose a high-hardness tensile flat steel.

[0006] To achieve the above objectives, this application adopts the following technical solution: a high-hardness tensile-strength flat steel, comprising a flat steel body, a square block fixedly connected to the surface of the flat steel body, two slots opened on the surface of the square block, two irregular blocks fixedly connected to the surface of the flat steel body, a rod slidably inserted into the irregular block, the size of the rod matching the size of the slot, and an operating block fixedly connected to one end of the rod.

[0007] Preferably, the arc surface of the insertion rod is fitted with a spring, and the two ends of the spring are fixedly connected to the irregular block and the operating block, respectively.

[0008] Preferably, a limiting groove is formed on the surface of the operating block, and a rotating rod is rotatably connected to the surface of the irregular block, with the end of the rotating rod away from the irregular block fixedly connected to the limiting block.

[0009] Preferably, the limiting block has a groove on the side away from the rotating rod, and a handle is fixedly connected to the surface of the groove of the limiting block.

[0010] Preferably, the arc surface of the rotating rod is fitted with a torsion spring, and the two ends of the torsion spring are fixedly connected to the irregular block and the limiting block, respectively.

[0011] Preferably, the surface of the irregularly shaped block is provided with a blocking groove, and a blocking block is fixedly connected to the surface of the blocking groove of the irregularly shaped block.

[0012] Preferably, a buffer pad is fixedly connected to the surface of the blocking block, and the size of the buffer pad is adapted to the size of the blocking block.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention achieves the effect of facilitating workers to quickly connect two flat steel bodies, avoiding the time-consuming and laborious process of traditional fixing methods, which often involve bolts and nuts, resulting in low installation efficiency. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figures 1-6As shown, this utility model provides a technical solution: a high-hardness tensile-strength flat steel, including a flat steel body 1, a square block 2 fixedly connected to the surface of the flat steel body 1, two slots 3 formed on the surface of the square block 2, and two irregularly shaped blocks 4 fixedly connected to the surface of the flat steel body 1. Insert rods 5 are slidably inserted into the irregularly shaped blocks 4, the size of the insert rods 5 being adapted to the size of the slots 3. An operating block 6 is fixedly connected to one end of the insert rods 5, achieving the effect of facilitating quick connection of two flat steel bodies 1 by workers, avoiding the difficulties encountered by workers when installing or disassembling the flat steel bodies 1, as traditional fixing methods often involve bolts and nuts. This results in time-consuming and laborious installation or disassembly for workers, leading to low installation efficiency. A spring 7 is fitted onto the arc surface of the insertion rod 5. The two ends of the spring 7 are fixedly connected to the irregular block 4 and the operating block 6, respectively. The rebound force of the spring 7 achieves the effect of automatically inserting the insertion rod 5 into the slot 3, while also restricting the movement of the insertion rod 5, thus improving the stability of the insertion rod 5 when fixing the flat steel body 1. A limit groove is formed on the surface of the operating block 6. A rotating rod 8 is rotatably connected to the surface of the irregular block 4. A limit block 9 is fixedly connected to the end of the rotating rod 8 away from the irregular block 4, thus restricting the movement of the operating block 6. As a result, the movement of the insertion rod 5 is indirectly restricted, which improves the stability of the insertion rod 5 when fixing the flat steel body 1. The limiting block 9 has a groove on the side away from the rotating rod 8, and a handle 10 is fixedly connected to the surface of the groove of the limiting block 9. The handle 10 facilitates the rotation of the limiting block 9 by the operator, avoiding the situation where the operator cannot easily rotate the limiting block 9 due to the lack of a suitable force point on the surface of the limiting block 9. A torsion spring 11 is sleeved on the arc surface of the rotating rod 8. The two ends of the torsion spring 11 are fixedly connected to the irregular block 4 and the limiting block 9, respectively. The torque of the torsion spring 11 automatically drives the limiting block 9. The rotation effect reduces the number of steps for operators and facilitates the next step of the operation. The surface of the irregular block 4 is provided with a blocking groove, and a blocking block 12 is fixedly connected to the surface of the blocking groove of the irregular block 4. The blocking block 12 can restrict the rotation of the limiting block 9, allowing the limiting block 9 to rotate to a suitable position. A buffer pad 13 is fixedly connected to the surface of the blocking block 12. The size of the buffer pad 13 is adapted to the size of the blocking block 12, and the buffer pad 13 can achieve a buffering effect, preventing the limiting block 9 from directly colliding with the surface of the blocking block 12, which could easily damage the limiting block 9 or the blocking block 12.

[0025] Working principle: When the operator needs to install two flat steel bodies 1 together, the square block 2 is moved between the two irregular blocks 4. As the square block 2 continues to move, when its surface contacts the insertion rod 5, it presses the rod 5 to both sides. At this time, the spring 7 is stretched, and the insertion rod 5 drives the operating block 6 to move. When the square block 2 moves to the appropriate position, the insertion rod 5 and the slot 3 are on the same horizontal plane. The operating block 6 then moves to the appropriate position, and the limiting block 9 completely disengages from the surface of the limiting groove of the operating block 6. The torque of the torsion spring 11 drives the limiting block 9 to rotate. When the limiting block 9 contacts the surface of the buffer pad 13, it stops rotating. The rebound force of the spring 7 drives the operating block 6 to move, and the operating block 6 drives the insertion rod... Move the rod 5 until it is inserted into the surface of the slot 3. At this point, the two flat steel bodies 1 are installed. When the operator needs to remove the two flat steel bodies 1, move the operating block 6. The spring 7 is stretched, and the operating block 6 moves the rod 5. When the rod 5 is completely removed from the surface of the slot 3, the rod 5 releases the fixation of the opposite square block 2. At this point, the operator can remove the two flat steel bodies 1. Turn the handle 10. The handle 10 drives the limit block 9 to rotate. The limit block 9 drives the rotating rod 8 to rotate. When the limit block 9 rotates to the appropriate position, move the operating block 6 until the limit block 9 moves to the surface of the limit groove of the operating block 6. At this point, the limit block 9 can restrict the movement of the operating block 6, thus facilitating the operator's next use.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
