Description

Technical Field

[0001] The utility model relates to the field of channel steel fasteners, in particular to a firmly fastened channel steel fastener. Background Art

[0002] Channel steel fasteners are a type of metal parts connected to channel steels. There are many types of channel steel fasteners: connecting different parts of channel steels, connecting channel steels to walls, or connecting other parts to channel steels through fasteners.

[0003] In the existing technology, when channel steel is connected to other components through fasteners, it is generally necessary to drill holes in the channel steel. This method will destroy the overall strength of the channel steel. Therefore, the use of fasteners can avoid the problem of reduced strength. However, after the external fasteners are connected to the channel steel, the connection force will decrease as the use time increases. Utility Model Content

[0004] The purpose of the present invention is to provide a firmly fastened channel steel fastener in order to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a firmly fastened channel steel fastener, comprising a fastener sleeved on the outer wall of the channel steel, a rotating stud being threadedly connected to the lower transverse plate portion of the fastener, a top block being integrally formed on the top of the rotating stud, a fastening assembly being rotatably connected to the outer periphery of the top block and penetrating to the lower side of the lower transverse plate portion of the fastener, and a ring member being rotatably connected to the bottom end of the rotating stud via a rotating assembly;

[0006] The rotating assembly is used to prevent the annular member from transmitting torque to the rotating stud;

[0007] The fastening assembly is used to improve the anti-loosening capability of the rotating stud. A hexagonal block is integrally formed below the outer periphery of the rotating stud. The hexagonal block is used to transmit torque to the rotating stud.

[0008] As a further solution of the present invention: the rotating assembly includes a rotating groove which is opened at the center of the bottom end of the rotating stud and is recessed upward, and the inner wall of the rotating groove is rotatably connected to a rotating ring, and the rotating ring is integrally formed at the top of the annular member.

[0009] As a further solution of the present invention, the fastening assembly includes an annular groove formed on the outer periphery of the top block, an annular block is rotatably connected to the inner wall of the annular groove, and two symmetrically arranged connecting ears are integrally formed on the outer periphery of the annular block;

[0010] The bottom end of the connecting ear is fixedly connected with a limiting stud which passes through the lower side of the lower horizontal plate portion of the fastener.

[0011] As a further solution of the present invention: the outer periphery of the limiting stud is located below the lower transverse plate portion of the fastener and is threadedly connected with a locking nut.

[0012] As a further solution of the present invention, the inner wall of the annular groove is consistent with the outer wall of the annular block, and the cross section of the annular groove and the annular block is a "convex" structure rotated ninety degrees.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By setting up a fastening component and a rotating component, the rotation of the rotating stud can be limited. If the rotating stud cannot rotate, the firmness of its connection can be improved. At the same time, the rotating component can effectively prevent the torque from being transmitted to the rotating stud, thereby ensuring the stability of the fastener connection.

[0019] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 3In an embodiment of the present invention, a firmly fastened channel steel fastener includes a fastener 1 sleeved on the outer wall of the channel steel, a rotating stud 2 is threadedly connected to the lower horizontal plate portion of the fastener 1, a top block 3 is integrally formed on the top of the rotating stud 2, the outer periphery of the top block 3 is rotatably connected to a fastening component that passes through the lower portion of the lower horizontal plate portion of the fastener 1, and the bottom end of the rotating stud 2 is rotatably connected to a ring member 5 through a rotating component; the rotating component is used to prevent the ring member 5 from transmitting torque to the rotating stud 2; the fastening component is used to improve the anti-loosening ability of the rotating stud 2, and a hexagonal block 4 is integrally formed below the outer periphery of the rotating stud 2, and the hexagonal block 4 is used to transmit torque to the rotating stud 2.

[0021] In this embodiment, the fastener 1 is first clamped on the fixed channel steel, and then a wrench is used to connect the hexagonal block 4. The hexagonal block 4 is rotated by the wrench. The hexagonal block 4 is driven by the force to rotate the rotating stud 2. Since the rotating stud 2 is threadedly connected to the lower horizontal plate of the fastener 1 and the fastener 1 cannot move, the rotating stud 2 is moved upward during the rotation process until the top block 3 is tightly pressed against the outer wall of the channel steel.

[0022] After the top block 3 is tightly pressed against the outer wall of the channel steel, the fastening assembly is fixed. The fastening assembly limits the up and down displacement of the rotating stud 2, thereby limiting the rotation of the rotating stud 2 and preventing it from loosening.

[0023] After the fastener 1 is fixed, when the ring member 5 is subjected to force, the force applied to the ring member 5 will not cause the rotating stud 2 to loosen because the force applied to the ring member 5 will not transmit torque to the rotating stud 2.

[0024] Please refer to Figure 2 The rotating assembly includes a rotating groove 9 which is opened at the center of the bottom end of the rotating stud 2 and is recessed upward. The inner wall of the rotating groove 9 is rotatably connected to a rotating ring 10 which is integrally formed at the top of the annular member 5.

[0025] In this embodiment, after the fastener 1 is fixed to the channel steel, the annular member 5 is rotated by force, and the annular member 5 drives the rotating ring 10 to rotate in the rotating groove 9, and the torque is not transmitted to the rotating stud 2.

[0026] Please refer to Figure 1 and Figure 2 The fastening assembly includes an annular groove 11 opened on the outer periphery of the top block 3, and the inner wall of the annular groove 11 is rotatably connected to the annular block 12. The outer periphery of the annular block 12 is integrally formed with two symmetrically arranged connecting ears 6; the bottom end of the connecting ear 6 is fixedly connected to a limiting stud 7 that passes through the lower horizontal plate portion of the fastener 1, and the outer periphery of the limiting stud 7 is located below the lower horizontal plate portion of the fastener 1 and is threadedly connected to a locking nut 8.

[0027] In this embodiment: when the hexagonal block 4 drives the rotating stud 2 to rotate, the rotating stud 2 moves upward synchronously. At this time, the limiting stud 7 moves upward accordingly without rotating, until the top block 3 is tightly pressed against the outer wall of the channel steel. At this time, a locking nut 8 is used to be threadedly connected to the limiting stud 7. The top of the effectively tightened locking nut 8 is tightly fitted with the bottom end of the lower horizontal plate of the fastener 1. At this time, the two limiting studs 7 cannot move up and down, thereby limiting the up and down movement of the rotating stud 2. The rotating stud 2 cannot move up and down, and therefore cannot rotate, thereby reinforcing the rotating stud 2 and preventing it from loosening.

[0028] Please refer to Figure 3 The inner wall of the annular groove 11 is consistent with the outer wall of the annular block 12, and the cross-section of the annular groove 11 and the annular block 12 is a "convex" structure rotated ninety degrees.

[0029] In this embodiment: as the top block 3 rotates along with the rotating stud 2, the top block 3 drives the annular groove 11 to rotate, and the annular groove 11 and the annular block 12 rotate relative to each other. The annular groove 11 moves upward synchronously during the rotation process, and the upward moving annular groove 11 drives the annular block 12 to move upward, thereby achieving the purpose of synchronous movement but non-synchronous rotation.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
