Description

Technical Field

[0001] This utility model relates to the technical field of wire rope accessories, and in particular to an anti-loosening fish-eye manganese steel structure. Background Technology

[0002] Fisheye manganese steel is a type of terminal connector used for steel wire ropes. It is mainly used to lock and tighten the steel wire rope and is a common type of hardware.

[0003] Most existing fisheye manganese steel cables use bottom limiting holes and threads to lock and tighten the wire rope. After long-term use, the wire rope deforms in the limiting hole, making it difficult to separate the wire rope from the fisheye manganese steel. Furthermore, when subjected to high pressure, the connection strength between the wire rope and the fisheye manganese steel is insufficient, which can easily lead to breakage and separation. There is room for improvement. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-loosening fisheye manganese steel structure to solve the problems mentioned in the background art, such as the difficulty in separating existing fisheye manganese steel connected to steel wire rope by thread and the insufficient connection strength when bearing large pressure, which easily leads to breakage and separation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-loosening fisheye manganese steel structure, including a positioning post and a wire rope assembly, wherein a fisheye hook is fixedly connected to the top of the positioning post, a slot is provided at the bottom of the positioning post, a strip-shaped hole is provided on the surface of the positioning post, and a limit component is fixedly connected to the surface of the positioning post. The wire rope assembly is used to insert into the positioning post, and the limiting assembly is used to fix the wire rope assembly inside the positioning post.

[0006] Preferably, the wire rope assembly includes a wire rope body, an insertion rod is fixedly connected to the top of the wire rope body, two guide rods are fixedly connected to the surface of the insertion rod, and two guide grooves adapted to the guide rods are opened on the inner wall of the slot.

[0007] Preferably, the surface of the insertion rod has two limiting grooves, the size of the two limiting grooves is the same as the size of the strip hole, and the positions of the two limiting grooves correspond to the positions of the strip hole.

[0008] Preferably, the limiting component includes a positioning ring, the top end of which is rotatably connected to a limiting sleeve, the inner wall of the limiting sleeve is rotatably connected to the surface of the positioning post, and the surface of the limiting sleeve is provided with two sets of positioning threaded grooves.

[0009] Preferably, the limiting sleeve has two arc-shaped cavities inside, and the front and rear inner walls of the two arc-shaped cavities are provided with sliding grooves. The inner walls of the sliding grooves are fixedly connected to positioning rods, and the surfaces of the positioning rods are fitted with springs. The inner walls of the two sliding grooves are slidably connected to sliders, and the opposite surfaces of the two sliders are fixedly connected to arc-shaped plates.

[0010] Preferably, the slider and the positioning rod are slidably connected, and one end of the spring overlaps with the inner wall of the groove, while the end of the spring away from the inner wall of the groove overlaps with the slider.

[0011] Preferably, limiting blocks are fixedly connected to the opposite faces of the two arc-shaped plates. The limiting blocks are adapted to the limiting groove and the strip hole respectively. Pull rods are fixedly connected to the opposite back faces of the two arc-shaped plates. The end of the pull rod away from the arc-shaped plate extends to the outside of the limiting sleeve and is fixedly connected to a circular plate. Two positioning bolts are threadedly connected to the side of the circular plate, and the positioning bolts are adapted to the positioning thread groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-loosening fisheye manganese steel structure, through the cooperation of the wire rope assembly and the limiting assembly, allows the insertion rod to be inserted into the slot inside the positioning post during use. Then, by rotating the limiting sleeve to align the limiting block with the strip hole, the spring loses its restraint and generates a reaction force to drive the limiting block through the strip hole and into the limiting groove on the surface of the insertion rod, thereby locking the wire rope body to the fisheye hook. The two limiting blocks ensure that the insertion rod cannot be dislodged from the slot, resulting in higher connection strength. Furthermore, during disassembly, only the two sets of positioning bolts need to be removed, and the limiting blocks can be dislodged from the limiting groove by the circular plate, pull rod, and arc plate, making the insertion rod and positioning post more convenient and quick to separate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an anti-loosening fisheye manganese steel structure, including a positioning post 1 and a steel wire rope assembly 2. The top of the positioning post 1 is fixedly connected to a fisheye hook 3, the bottom of the positioning post 1 is provided with a slot, the surface of the positioning post 1 is provided with a strip hole 4, and the surface of the positioning post 1 is fixedly connected to a limit assembly 5. The wire rope assembly 2 is used to insert into the positioning post 1, and the limiting assembly 5 is used to fix the wire rope assembly 2 inside the positioning post 1.

[0017] Furthermore, the wire rope assembly 2 includes a wire rope body 201, with an insertion rod 202 fixedly connected to the top of the wire rope body 201. Two guide rods 203 are fixedly connected to the surface of the insertion rod 202. Two guide grooves 204 adapted to the guide rods 203 are opened on the inner wall of the slot. Two limiting grooves 205 are opened on the surface of the insertion rod 202. The size of the two limiting grooves 205 is the same as the size of the strip hole 4, and the position of the two limiting grooves 205 corresponds to the position of the strip hole 4. After aligning the guide rods 203 with the guide grooves 204, the insertion rod 202 can be inserted into the slot. Due to the cooperation of the guide grooves 204 and the guide rods 203, it can be ensured that the position of the two limiting grooves 205 corresponds to the position of the strip hole 4.

[0018] Furthermore, the limiting component 5 includes a positioning ring 501, the top end of which is rotatably connected to a limiting sleeve 502. The inner wall of the limiting sleeve 502 is rotatably connected to the surface of the positioning post 1. The surface of the limiting sleeve 502 has two sets of positioning threaded grooves. The interior of the limiting sleeve 502 has two arc-shaped cavities. The front and rear inner walls of the two arc-shaped cavities are provided with sliding grooves. The inner walls of the sliding grooves are fixedly connected to positioning rods 503. The surface of the positioning rods 503 is fitted with springs 504. The inner walls of the two sliding grooves are slidably connected to sliders 505. The opposing surfaces of the two sliders 505 are fixedly connected to arc-shaped plates 506. The sliders 505 are slidably connected to the surface of the positioning rods 503, and the springs 504 are also slidably connected to the surface of the positioning rods 503. One end of the spring 504 overlaps with the inner wall of the chute, and the end of the spring 504 away from the inner wall of the chute overlaps with the slider 505. Limiting blocks 507 are fixedly connected to the opposite faces of the two arc-shaped plates 506. The limiting blocks 507 are respectively adapted to the limiting groove 205 and the strip hole 4. Pull rods 508 are fixedly connected to the opposite back faces of the two arc-shaped plates 506. The end of the pull rod 508 away from the arc-shaped plate 506 extends to the outside of the limiting sleeve 502 and is fixedly connected to a circular plate 509. Two positioning bolts 510 are threadedly connected to the side of the circular plate 509, and the positioning bolts 510 are adapted to the positioning thread groove. After inserting the insertion rod 202 into the slot, the limiting sleeve 502 is rotated, and the limiting sleeve 505... 2. The internal arc-shaped cavity can be rotated. During the rotation, the limiting insert 507 always presses against the surface of the positioning post 1, and the arc plate 506 and the slider 505 compress the spring 504 on the surface of the positioning rod 503. When the limiting insert 507 rotates to the position of the strip hole 4, the spring 504 loses its restraint and generates a reaction force. Through the slider 505 and the arc plate 506, the limiting insert 507 passes through the strip hole 4 and inserts into the limiting groove 205 on the surface of the insertion rod 202, thereby locking the position of the insertion rod 202 in the slot. At the same time, after the arc plate 506 moves inward, it can drive the circular plate 509 to approach the limiting sleeve 502 through the pull rod 508. When contact is made, the circular plate 509 is locked by screwing two sets of positioning bolts 510 into the positioning thread groove. This ensures that the circular plate 509 and the pull rod 508 cannot move the arc plate 506 outward, thus ensuring the stability of the limiting insert 507 within the limiting groove 205. During disassembly, simply remove the positioning bolts 510, and then move the arc plate 506 outward using the circular plate 509 and the pull rod 508 to disengage the limiting insert 507 from the limiting groove 205. This quickly separates the insertion rod 202 from the positioning post 1, improving the connection strength between the wire rope body 201 and the fisheye hook 3, and making separation more convenient and faster.

[0019] Working principle: First, align the two guide rods 203 on the surface of the insertion rod 202 with the guide groove 204, and insert it through the slot at the bottom of the positioning post 1. At this time, rotate the limiting sleeve 502, which can drive the two arc-shaped cavities inside to rotate. The limiting block 507 always presses against the surface of the positioning post 1 and drives the slider 505 to squeeze the spring 504 on the surface of the positioning rod 503. When the limiting block 507 moves to the position of the strip hole 4, the two springs 504 are no longer restricted. Through the slider 505 and the arc plate 506, the limiting block 507 is driven to pass through the strip hole 4 and insert into the limiting groove 205 on the surface of the insertion rod 202, thereby locking the position of the insertion rod 202 in the slot and ensuring that the wire rope body 201 cannot be positioned. When column 1 is disengaged, the two arc-shaped plates 506 move inward. The arc-shaped plates 506 can drive the circular plate 509 to contact the surface of the limiting sleeve 502 through the pull rod 508. After the two positioning bolts 510 are screwed into the positioning thread groove, the circular plate 509 cannot drive the arc-shaped plate 506 to move outward through the pull rod 508. Therefore, it can be ensured that the limiting insert 507 is stable in the limiting groove 205 and will not disengage. When it is necessary to separate the wire rope body 201 from the positioning column 1, simply remove the two sets of positioning bolts 510 and drive the arc-shaped plate 506 to move outward through the circular plate 509 and the pull rod 508 to separate the limiting insert 507 from the limiting groove 205, so that the insertion rod 202 can be quickly removed from the slot.
