Technical Field

[0001] The utility model relates to the technical field of bolt fasteners, and particularly relates to a bolt fastener with a limiting mechanism. Background Technique

[0002] Bolt fasteners are a type of mechanical parts, mainly used for firmly connecting two parts with through holes. This connection form is called bolt connection, which belongs to detachable connection. Bolts usually consist of two parts: a head and a screw rod (a cylinder with external threads), and need to be used in conjunction with nuts to firmly connect two parts with through holes. Bolt connection allows the two parts to be separated by unscrewing the nut. Therefore, it is a detachable connection method. An anchor bolt is a type of bolt connection form. After assembly, only the nut part is detachable, while the screw rod part is fixed to the concrete base material in a certain form and cannot be separated.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , a bolt fastener with a limiting mechanism, including a fastening nut 2, a fastening bolt 1 is threadedly installed inside the fastening nut 2, a limit threaded hole 3 is opened inside the fastening bolt 1, and a limit threaded rod 7 is threadedly installed inside the limit threaded hole 3; the threading direction of the fastening bolt 1 is opposite to the threading direction of the limit threaded rod 7, a hexagonal plate 4 is fixedly installed on the right side of the limit threaded rod 7, six limit moving holes 10 are installed inside the hexagonal plate 4, and a limit rod 8 is passed through the limit moving holes 10; the diameter size of the limit rod 8 matches the diameter size of the limit moving holes 10, and the limit rod 8 realizes moving inside the limit moving holes 10, an operating circular plate 6 is fixedly installed on the right side of the limit rod 8, a connecting bearing 5 is installed inside the hexagonal plate 4, and an adjusting bolt 11 is passed through the operating circular plate 6; the hexagonal plate 4 is movably connected to the adjusting bolt 11 through the connecting bearing 5, and the adjusting bolt 11 is threadedly connected to the operating circular plate 6; a limit groove 9 is opened on the right surface of the fastening nut 2; there are six limit grooves 9, and the limit grooves 9 correspond to the limit rods 8 one by one, and the inner diameter size of the limit grooves 9 matches the diameter size of the limit rods 8; by providing six limit rods 8 and limit grooves 9, the fastening nut 2 and the hexagonal plate 4 are connected together, so that the fastening nut 2 and the limit threaded rod 7 cannot rotate simultaneously, thereby realizing the limitation of the fastening nut 2 at any position, facilitating the fastening of objects with different thicknesses, and achieving an anti-loosening effect.

[0020] Working principle: When using the bolt fastener with a limiting mechanism, first use the fastening bolt 1 and the fastening nut 2 to fasten two objects that need to be fastened together. Then, screw the limiting threaded rod 7 into the internal limiting threaded hole 3, and at the same time adjust the position of the limiting rod 8 so that the limiting rod 8 is aligned with the limiting groove 9. Secondly, turn the adjusting bolt 11, and through the thread, push the operating circular plate 6 to approach the hexagonal plate 4, thereby pushing the limiting rod 8 to move inside the limiting moving hole 10, so that the limiting rod 8 is inserted into the internal limiting groove 9 to connect the hexagonal plate 4 and the fastening nut 2. Since the thread directions of the fastening bolt 1 and the limiting threaded rod 7 are opposite, when the hexagonal plate 4 and the fastening nut 2 rotate in the same direction, they approach or move away from each other, realizing that the objects to be fastened on both sides of the fastening nut 2 and the hexagonal plate 4 are blocked and cannot move, playing a limiting role. This is the working principle of the bolt fastener with a limiting mechanism.
