Description

Technical Field

[0001] This utility model relates to the field of nylon cable ties, specifically a self-locking nylon cable tie. Background Technology

[0002] Self-locking nylon cable ties are primarily made of nylon. Nylon is a polyamide synthetic fiber with excellent abrasion resistance, toughness, and chemical resistance. This allows the cable ties to be used in various environmental conditions without easily being damaged. They are typically long and narrow, with a movable locking mechanism at one end; this locking mechanism is the key component of the self-locking nylon cable tie. The main body of the cable tie contains numerous equidistant serrated structures; these serrations engage with the locking mechanism to achieve the self-locking function.

[0003] The announcement number is CN220905911U, specifically regarding a wear-resistant bidirectional self-locking nylon cable tie. It includes a pull strap body, a fixing seat fixedly mounted on the base surface of the pull strap body, a limit hole at the top of the fixing seat, and a bolt connected to the base surface of the fixing seat via an internal threaded groove. One end of the bolt is connected to a push-pull plate via a bearing. In existing self-locking nylon cable ties, under normal use, when the cable tie passes through the object to be bundled and is tightened, the elastic block tightly engages with the threaded rod within the limit groove, effectively preventing the cable tie from loosening, thus achieving the self-locking function. However, in practical applications, the cable tie often needs to be fixed in areas prone to shaking. In devices such as the wiring systems of vehicles, vibrations during vehicle operation can cause the cable ties securing the wire harness to sway continuously. When the rotational force and the lateral movement force are close together, the elastic clip may move out of the limiting groove. Subsequently, under the rotational force generated by the swaying, the threaded rod will rotate. This rotation will directly destroy the originally stable self-locking structure, causing the clip to loosen. The loosening of the clip greatly increases the risk of self-locking failure, making it impossible for the cable tie to reliably maintain its bundled state. This may lead to a series of problems, such as circuit failures caused by loose wire harnesses, and loose cable ties may snag on other components, affecting the normal operation of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a self-locking nylon cable tie. When this device is used, it solves the problem that when the distance between the rotational force and the lateral movement force is short, the elastic block may move out of the limiting groove. Subsequently, under the rotational force generated by shaking, the threaded rod will rotate. This rotation will directly destroy the originally stable self-locking structure, causing the buckle to loosen. The loosening of the buckle greatly increases the risk of self-locking failure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a self-locking nylon cable tie, comprising a cable tie body, a fixing block fixedly connected to one end of the cable tie body, a first hole disposed inside one side of the fixing block, a rotating component disposed inside the other side of the fixing block, and an elastic mechanism disposed on one side of the rotating component.

[0006] The first hole has a first groove connected to one side of its interior. The rotating component includes a locking block disposed inside the first groove. The end of the locking block away from the cable tie body is rotatably connected to a threaded rod. The threaded rod is connected to the fixing block by a threaded connection. The middle of the side of the fixing block away from the cable tie body is connected to a second groove. A sliding block is disposed inside the second groove. A torsion spring is fixedly connected to the side of the sliding block away from the cable tie body. A rotating disk is fixedly connected to the side of the torsion spring away from the cable tie body. The sliding block has a second hole inside its interior.

[0007] Preferably, the outer side of the sliding block fits against the inner side of the second groove, and the sliding block has a rectangular shape.

[0008] Preferably, the width of the second hole is greater than the width of the threaded rod, and the threaded rod is nested inside the threaded rod.

[0009] Preferably, the elastic mechanism includes a fixed rod fixedly connected to the outside of the rotating disk, a third groove is provided inside the threaded rod, a spring is fixedly connected inside the third groove, a rotating rod is fixedly connected to one end of the spring, and a limit rod is fixedly connected to the other end of the rotating rod.

[0010] Preferably, the inner side of the third groove fits the outer side of the rotating rod, and the external structural shape of the rotating rod is cylindrical.

[0011] Preferably, one side of the limiting rod is an inclined surface, and the length of the limiting rod is greater than the depth of the limiting groove.

[0012] This utility model proposes a self-locking nylon cable tie, which, by setting a rotating component and an elastic mechanism, allows the elastic mechanism to reset when the rotating component resets due to vibration forces in the rotational direction and lateral movement. Compared with the prior art, it can reset again after the limit fails, thereby reducing the risk of self-locking failure. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 The present invention provides a technical solution: a self-locking nylon cable tie, comprising a cable tie body 1, a fixing block 2 fixedly connected to one end of the cable tie body 1, a first hole 3 disposed inside one side of the fixing block 2, a rotating component 4 disposed inside the other side of the fixing block 2, and an elastic mechanism 5 disposed on one side of the rotating component 4.

[0020] The first hole 3 has a first groove 6 inside one side. The rotating component 4 includes a locking block 401 disposed inside the first groove 6. The end of the locking block 401 away from the cable tie body 1 is rotatably connected to a threaded rod 402. The threaded rod 402 is connected to the fixing block 2 by a threaded connection. The middle of the side of the fixing block 2 away from the cable tie body 1 has a second groove 403. A sliding block 404 is disposed inside the second groove 403. The outer side of the sliding block 404 fits against the inner side of the second groove 403, and the sliding block 404 has a rectangular shape. The shape is such that the sliding block 404 will not rotate when it moves inside the second groove 403. A torsion spring 405 is fixedly connected to the side of the sliding block 404 away from the cable tie body 1. A rotating disk 406 is fixedly connected to the side of the torsion spring 405 away from the cable tie body 1. A second hole 407 is provided inside the sliding block 404. The width of the second hole 407 is greater than the width of the threaded rod 402, and the threaded rod 402 is nested inside the threaded rod 402, so that the sliding block 404 will not slide laterally when the threaded rod 402 rotates.

[0021] The elastic mechanism 5 includes a fixed rod 501 fixedly connected to the outside of the rotating disk 406. A third groove 502 is provided inside the threaded rod 402. A spring 503 is fixedly connected inside the third groove 502. A rotating rod 504 is fixedly connected to one end of the spring 503. A limiting rod 505 is fixedly connected to the other end of the rotating rod 504. The inner side of the third groove 502 is in contact with the outer side of the rotating rod 504. The rotating rod 504 has a cylindrical shape, which allows it to rotate inside the third groove 502. One side of the limiting rod 505 is an inclined surface, and the length of the limiting rod 505 is greater than the depth of the limiting groove 506, which allows the fixed rod 501 to push the limiting rod 505 along the inclined side of the limiting rod 505 to reset it.

[0022] When a vibration force occurs in the direction of rotation, it causes the rotating disk 406 and the fixed rod 501 to rotate, causing the threaded rod 402 to rotate, which in turn causes the locking block 401 to move laterally. Because one side of the limiting rod 505 is an inclined surface and the length of the limiting rod 505 is greater than the depth of the limiting groove 506, the fixed rod 501 is blocked by the limiting rod 505, the threaded rod 402 cannot continue to rotate, and the locking block 401 cannot continue to move laterally out of the buckle of the cable tie body 1. At this time, the stored force of the torsion spring 405 will drive the rotating disk 406 and the fixed rod 501 to reset.

[0023] When a lateral vibration occurs, the threaded rod 402 is difficult to move laterally because the connection between the threaded rod 402 and the fixed block 2 is a threaded connection.

[0024] When the vibration force in the rotational direction and the vibration force in the lateral movement occur at a short interval, and the spring 503, rotating rod 504, and limiting rod 505 are ejected from the inner side of the limiting groove 506, the rotational force causes the rotating disk 406 and the fixed rod 501 to rotate. Since the fixed rod 501 is not limited by the limiting rod 505, it will rotate at a larger angle, causing the threaded rod 402 to rotate and drive the locking block 401 to move laterally out of the buckle of the cable tie body 1. When the vibration force disappears, the fixing rod 501 resets under the action of the torsion spring 405. At this time, the limiting rod 505 also resets. Since one side of the limiting rod 505 is an inclined surface and the length of the limiting rod 505 is greater than the depth of the limiting groove 506, when the fixing rod 501 resets, it moves along the inclined side of the limiting rod 505 to the other side of the limiting rod 505, so that the locking block 401 moves laterally again into the buckle of the cable tie body 1 to fix the cable tie body 1 and reduce the risk of self-locking failure.
