Description

Technical Field

[0001] The utility model relates to a self-locking cable tie, belonging to the field of cable ties. Background Art

[0002] Cable ties are divided into metal cable ties (generally made of stainless steel) and plastic cable ties (generally made of nylon), and are commonly used for cables of electromechanical products, computer, electronic products and automotive wire harnesses, etc.

[0003] The existing cable ties complete the step of packaging materials after being locked. The structure of this kind of cable tie is generally the engagement of a tooth and a slot. The force after the engagement and fixation of the tooth and the slot is in the opposite direction to the force applied by the material to prevent the cable tie from scattering. However, the cable tie with this structure is prone to the problem that the wire loosens, resulting in the disconnection of the connection between the tooth and the slot, and the phenomenon of loose engagement, which is likely to cause the scattering of materials. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the disadvantages and deficiencies existing in the prior art, and provide a self-locking cable tie.

[0005] A self-locking cable tie includes a locking part and a connecting part used for engaging and locking the cable tie with the locking part. First and second slot groups composed of teeth are arranged on both sides of the connecting part. A clamping slot is arranged on the locking part. The locking part is also provided with a self-locking structure. The self-locking structure includes a sliding slot arranged on the locking part. A locking piece and a button sleeved on the end of the locking piece are slidably arranged in the sliding slot. A locking block used for locking with the second slot group is arranged at the bottom of the locking piece. A limiting ring is arranged on the locking piece. A first spring and a limiting plate are sleeved outside the locking piece. One end of the first spring abuts against the limiting ring, and the other end abuts against the limiting plate. A groove is arranged on the outer wall of the locking piece. A ball matching the groove is arranged on the other side of the limiting plate. The locking piece makes the locking block engage and lock with the second slot group under the action of the first spring. The locking part is provided with a self-locking structure, so that the cable tie can be automatically locked after installation, avoiding accidental loosening during use and ensuring the fixing effect of the cable tie. Through the design of the button and the sliding slot, the operation process is intuitive and simple, and the user can easily apply or release the lock. The matching design of the ball and the groove limits the movement of the locking piece, avoiding unlocking caused by misoperation and enhancing the safety.

[0006] Preferably, an adjustment groove is provided inside the button. Installation grooves located inside the adjustment groove are provided on both sides of the top of the locking member.
