[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] See also Figure 1-4 A steel member fastening device comprises an I-beam 1, a first fastener 2 is sleeved on the outer wall of the I-beam 1, a fixing ear 7 is integrally formed at the edge of the first fastener 2, a fixing sleeve 3 is sleeved on the outer wall of the fixing ear 7, fixing bolts 4 are penetrated through the outer walls of the fixing ear 7 and the fastening sleeve 3, a loosening component 5 is arranged between the fixing bolt 4 and the outer surface of the fastening sleeve 3, the loosening component 5 comprises an upper washer 51 tightly fitted on the inner wall of the fixing bolt 4, a lower washer 52 is arranged on one side of the upper washer 51, a second bite tooth 57 is arranged on the side of the upper washer 51 close to the lower washer 52, a first bite tooth 56 is arranged on the side of the lower washer 52 close to the upper washer 51, and the first bite tooth 56 and the second bite tooth 57 are engaged with each other.

[0028] For further information, see Figure 3 A through slot 54 is provided in the middle of the outer wall of the upper washer 51 and the lower washer 52 . The through slot 54 allows the release assembly 5 to be smoothly sleeved between the fixing bolt 4 and the fastening sleeve 3 .

[0029] For further information, see Figure 3 An upper anti-slip tooth 53 is provided on the surface of the upper washer 51 away from the lower washer 52, and a lower anti-slip tooth 55 is provided on the surface of the lower washer 52 away from the upper washer 51. By arranging the upper anti-slip teeth 53 and the lower anti-slip teeth 55, the upper anti-slip teeth 53 and the lower anti-slip teeth 55 can be embedded in the interior of the contact surface after the release component 5 is completely fixed as a whole.

[0030] In addition, the specific number of the first fasteners 2 is two, and the two first fasteners 2 are tightly fitted on both sides of the I-beam 1 at the same time. It should be noted that the inclination angle of the first engaging tooth 56 and the second engaging tooth 57 is greater than the angle of the thread on the outer wall of the fixing bolt 4.

[0031] In specific implementation, after the two I-beams 1 are docked, the user can clamp the two first fasteners 2 on the outer wall of the I-beam 1, then cover the fastening sleeve 3 on the top surface of the two fixing ears 7, and then insert the fixing bolt 4 into the through groove 54 opened on the outer wall of the fastening sleeve 3 and the fixing ear 7. Before insertion, the loosening component 5 needs to be sleeved on the outer wall of the fixing bolt 4. After the loosening component 5 passes through the fastening sleeve 3 and the fixing ear 7, the fixing nut 6 is installed on the outer wall of the fixing bolt 4, and the fixing bolt 4 is tightened thoroughly.

[0032] After the conventional fastening device completes the initial fastening, the fixing bolts 4 used for fixing are prone to loosening during the subsequent long-term use, which not only creates a safety hazard but also affects the effect of the fastening device.

[0033] In the present invention, by sleeved the release component 5 on the outer wall of the fixing bolt 4 and tightening the fixing bolt 4, the lower anti-slip teeth 55 are embedded in the interior of the tightening sleeve 3 and the upper anti-slip teeth 53 are embedded in the interior of the fixing bolt 4, so that the upper and lower bottom surfaces of the release component 5 are fixed, and only relative movement between the first bite teeth 56 and the second bite teeth 57 is allowed. When the fixing bolt 4 is subjected to vibration or dynamic load, the angle between the first bite teeth 56 and the second bite teeth 57 is greater than the angle of the thread of the fixing bolt 4, and the first bite teeth 56 and the second bite teeth 57 will be displaced and lifted. This wedging effect prevents any loosening tendency of the fixing bolt 4 because the lifting distance between the upper washer 51 and the lower washer 52 is greater than the lifting distance of the fixing bolt 4 caused by thread sliding, thereby ensuring the long-term tightening of the bolt connection.

[0034] By setting up the loosening component 5, the fixing bolt 4 will not be easily loosened by utilizing the loosening component 5 after the fixing is completed, so that the two fixing ears 7 can provide effective fastening for the connection between the two I-beams 1 for a long time. At the same time, the user can complete the disassembly of the fixing bolt 4 and the loosening component 5 by direct reversal, which is convenient for recycling the fixing bolt 4 and the loosening component 5, thereby increasing the practicality of the device.

[0035] Embodiment 2

[0036] Based on Example 1, please refer to Figure 4 A steel component fastening device, optionally, a second fastener 8 is provided on one side of the first fastener 2, a sleeve rod 82 is fixedly connected to the bottom surface of the second fastener 8, a through groove 54 is opened inside the sleeve rod 82, a moving rod 83 is slidably provided in the through groove 54, and a retaining plate 81 is fixedly connected to the bottom surface of the moving rod 83.

[0037] For further information, see Figure 4A tension spring 84 is fixedly connected between the retaining plate 81 and the bottom surface of the second fastener 8. The tension spring 84 is sleeved on the periphery of the sleeve rod 82 and the movable rod 83. The number of the retaining plate 81, the sleeve rod 82, the movable rod 83 and the tension spring 84 are multiple and are evenly distributed on one side of the second fastener 8.

[0038] In specific implementation, the fastening device needs to fix a variety of steel components, among which, in addition to the I-beam 1, circular steel components are also common. When fastening the circular steel component, the second fastener 8 can be embedded in the first fastener 2, and then a longer fixing bolt 4 is used to connect the two fixing ears 7.

[0039] During the process, the first fastener 2 and the second fastener 8 are directly mounted on the outer wall of the circular steel component, and then the two fixing ears 7 are fixed by a longer fixing bolt 4 in conjunction with the loosening assembly 5 and the fixing nut 6. When fixing the connection of the circular steel component, the tension spring 84 arranged on one side of the two second fasteners 8 will first contact the surface of the steel component, and the shape of the surface of the steel component is not flat. In the process of the two fixing ears 7 approaching, the retaining plate 81 in the middle part will drive the moving rod 83 to move in the direction of the sleeve rod 82 until the moving rod 83 retracts to the inner retaining plate 81 of the sleeve rod 82 and fits tightly to the top of the sleeve rod 82. The closer it moves to the edge of the steel component, the smaller the resistance to the retaining plate 81 will be, and the presence of the tension spring 84 will support the retaining plate 81 to always be in the extreme position.

[0040] After the retaining plate 81 in the middle position hits the sleeve rod 82, the fixing bolt 4 and the fixing nut 6 can no longer be tightened. At this time, the retaining plate 81 in the middle position will directly tighten the circular steel component, and the other retaining plates 81 will assist the retaining plate 81 in the middle position, using its own position to limit the circular steel component, thereby further tightening the circular steel component.

[0041] By providing the second fastener 8, the device can not only fasten the I-beam 1, but also achieve a better fastening effect on circular steel members with special shapes, thereby increasing the application scope of the device.

[0042] Working principle: After the two I-beams 1 are connected, the user can clamp the two first fasteners 2 on the outer wall of the I-beam 1, then cover the fastening sleeve 3 on the top surface of the two fixing ears 7, and then insert the fixing bolt 4 into the through groove 54 opened on the outer wall of the fastening sleeve 3 and the fixing ear 7. Before insertion, the loosening component 5 needs to be sleeved on the outer wall of the fixing bolt 4. After the loosening component 5 passes through the fastening sleeve 3 and the fixing ear 7, the fixing nut 6 is installed on the outer wall of the fixing bolt 4, and the fixing bolt 4 is tightened thoroughly.

[0043] After the conventional fastening device completes the initial fastening, the fixing bolts 4 used for fixing are prone to loosening during the subsequent long-term use, which not only creates a safety hazard but also affects the effect of the fastening device.

[0044] In the present invention, by sleeved the release component 5 on the outer wall of the fixing bolt 4 and tightening the fixing bolt 4, the lower anti-slip teeth 55 are embedded in the interior of the tightening sleeve 3 and the upper anti-slip teeth 53 are embedded in the interior of the fixing bolt 4, so that the upper and lower bottom surfaces of the release component 5 are fixed, and only relative movement between the first bite teeth 56 and the second bite teeth 57 is allowed. When the fixing bolt 4 is subjected to vibration or dynamic load, the angle between the first bite teeth 56 and the second bite teeth 57 is greater than the angle of the thread of the fixing bolt 4, and the first bite teeth 56 and the second bite teeth 57 will be displaced and lifted. This wedging effect prevents any loosening tendency of the fixing bolt 4 because the lifting distance between the upper washer 51 and the lower washer 52 is greater than the lifting distance of the fixing bolt 4 caused by thread sliding, thereby ensuring the long-term tightening of the bolt connection.

[0045] The fastening device needs to fix a variety of steel components, among which, in addition to the I-beam 1, circular steel components are also common. When fastening the circular steel component, the second fastener 8 can be embedded in the first fastener 2, and then a longer fixing bolt 4 is used to connect the two fixing ears 7.

[0046] During the process, the first fastener 2 and the second fastener 8 are directly mounted on the outer wall of the circular steel component, and then the two fixing ears 7 are fixed by a longer fixing bolt 4 in conjunction with the loosening assembly 5 and the fixing nut 6. When fixing the connection of the circular steel component, the tension spring 84 arranged on one side of the two second fasteners 8 will first contact the surface of the steel component, and the shape of the surface of the steel component is not flat. In the process of the two fixing ears 7 approaching, the retaining plate 81 in the middle part will drive the moving rod 83 to move in the direction of the sleeve rod 82 until the moving rod 83 retracts to the inner retaining plate 81 of the sleeve rod 82 and fits tightly to the top of the sleeve rod 82. The closer it moves to the edge of the steel component, the smaller the resistance to the retaining plate 81 will be, and the presence of the tension spring 84 will support the retaining plate 81 to always be in the extreme position.

[0047] After the retaining plate 81 in the middle position hits the sleeve rod 82, the fixing bolt 4 and the fixing nut 6 can no longer be tightened. At this time, the retaining plate 81 in the middle position will directly tighten the circular steel component, and the other retaining plates 81 will assist the retaining plate 81 in the middle position, using its own position to limit the circular steel component, thereby further tightening the circular steel component.

[0048] By setting up the loosening component 5, the fixing bolt 4 will not be easily loosened by utilizing the loosening component 5 after the fixing is completed, so that the two fixing ears 7 can provide effective fastening for the connection between the two I-beams 1 for a long time. At the same time, the user can complete the disassembly of the fixing bolt 4 and the loosening component 5 by direct reversal, which is convenient for recycling the fixing bolt 4 and the loosening component 5, thereby increasing the practicality of the device.

[0049] By providing the second fastener 8, the device can not only fasten the I-beam 1, but also achieve a better fastening effect on circular steel members with special shapes, thereby increasing the application scope of the device.
