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 (usually made of stainless steel) and plastic cable ties (usually 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 snap-fit of teeth and slots. The force after the snap-fix of teeth and slots is in the opposite direction to the force exerted by the materials to prevent the cable tie from falling apart. However, the cable tie with this structure is prone to the problem that the wire loosens, resulting in the connection failure between the teeth and the slots, causing the bundling to be not tight and affecting the transportation and storage of materials. Content of the Utility Model

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

[0005] A self-locking cable tie includes a body. A buckle part and a connection part that can be inserted into the buckle part for fixed connection are provided at the end of the body. A first tooth group that is snap-connected to the buckle part is provided on the connection part. A second tooth group is provided on the other side of the connection part. A strengthening structure that is snap-connected to the second tooth group is provided on the buckle part. The strengthening structure includes an installation cavity arranged in the buckle part. A spring plate is installed in the installation cavity. One end of the spring plate extends out of the installation cavity and is snap-connected to any tooth in the second tooth group. By setting the snap-connection between the second tooth group and the spring plate in the strengthening structure, on the basis of the snap-connection between the first tooth group and the buckle part, the snap-connection firmness of the cable tie can be strengthened, preventing the materials from falling apart, improving the transfer reliability of the materials, and avoiding the influence of the failure of the snap-connection of the cable tie on the production efficiency.

[0006] Further, one end of the spring plate extending out of the installation cavity is in a hook shape, and the other end is provided with a bent fixed end. Setting one end of the spring plate extending out of the installation cavity in a hook shape can be snap-connected to the second tooth group to assist in strengthening the snap-connection between the first tooth group and the buckle part.

[0007] Preferably, a positioning pin is fixed on the inner wall of the installation cavity, and the positioning pin extends into the bending gap of the fixed end and is snap-connected thereto. The positioning pin can be snap-connected to the bending gap of the fixed end to help fix the position of the positioning pin in the installation cavity without moving, preventing the problem of the failure of the strengthening structure.

[0008] Further, the bending gap is in a conical shape or a trapezoidal shape. Setting it in a conical shape or a trapezoidal shape can increase the contact area between the positioning pin and the fixed end, ensuring the stable installation of the spring plate.

[0009] Further, a limit pin is provided on the side of the fixed end opposite to the positioning pin. A limit groove is provided in the installation cavity. A spring is sleeved outside the limit pin. One end of the spring is fixed on the fixed end, and the other end is fixed at the bottom of the limit groove. With the cooperation of the limit pin and the spring, the spring plate can have a certain flexibility, enabling the connecting portion to be smoothly inserted into the buckle portion and then clamped.

[0010] Further, the installation cavity communicates with a clamping channel. A clamping hole for the connecting portion to penetrate is provided on the buckle portion. One end of the spring plate extends into the clamping hole through the clamping channel for clamping with the second tooth group.

[0011] Preferably, a bent buckle for clamping with the second tooth group is provided in the clamping hole. The spring plate and the bent buckle are arranged oppositely. The bent buckle and the spring plate cooperate to clamp the upper and lower sides of the connecting portion, making the fixing effect of the cable tie better, the tightening effect more firm, and improving the use effect and service life of the cable tie.

[0012] The beneficial effects of the present utility model are as follows: By setting the second tooth group and clamping the spring plate in the strengthening structure, on the basis of the clamping connection between the first tooth group and the buckle portion, the clamping firmness of the cable tie can be strengthened, preventing the material from scattering, improving the transfer reliability of the material, and avoiding the failure of the clamping connection of the cable tie from affecting the production efficiency.
