Description

Technical Field

[0001] The utility model relates to an anti-retraction cable tie and belongs 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). They are commonly used in cables of electromechanical products, computers, electronic products and automotive wiring harnesses, etc.

[0003] The existing cable ties complete the step of packaging materials after being locked. The structure of such cable ties is generally a clamping fit of a clamping tooth and a clamping slot. The force after the clamping and fixing of the clamping tooth and the clamping slot is in the opposite direction to the force applied by the material to prevent the cable tie from falling off. However, the cable ties with such a structure are prone to loose wires, resulting in failure of the connection between the clamping tooth and the clamping slot, resulting in a loose clamping phenomenon, which makes the connection between the clamping tooth and the clamping slot fail, resulting in a poor bundling effect of the cable tie, hindering the improvement of production efficiency and production rhythm. Utility Model Content

The bottom of the anti-backward rod can be extended and retracted. After the cable tie is tied, the bottom of the anti-backward rod is pressed to a state of being engaged with the second tooth group, and the limiting gear is rotated so that the end face of the anti-backward rod abuts against the bottom face of the limiting gear to form a limit, thereby keeping the anti-backward rod in an extended state, thereby improving the stability and practicality of the cable tie.

[0006] Furthermore, a clamping groove is provided on the limiting gear, and the anti-backward rod includes a moving part. The moving part is tightly matched with the clamping groove when the cable tie is not in use. When the cable tie is in use, the moving part is pressed into the limiting cavity and then the limiting gear is rotated so that the clamping groove and the moving part form a vertical position setting with each other. The anti-backward rod is limited by the limiting gear, and the limiting gear is installed on the buckle part by rotating and clamping through a slider. The structure is simple, easy to process, and flexible.

[0007] Preferably, the anti-retraction rod also includes a connecting rod arranged at the top of the movable part, and the top of the connecting rod is connected to a rotating rod extending from a clamping groove, and the rotating rod abuts against the end face of the limiting gear when the cable tie is in use.

[0010] Furthermore, a limiting channel is provided at the bottom of the limiting cavity, and the limiting channel extends from the bottom of the anti-backward rod for engaging with the second locking tooth group.

[0011] Preferably, the buckle portion is provided with an insertion hole, a bent clamping portion is fixed in the insertion hole, and docking clamping teeth for clamping with the first clamping tooth group are evenly distributed on the clamping portion.

[0012] The beneficial effects of the utility model are as follows: by setting up the anti-backward structure, the anti-backward rod and the second clamping tooth group can be clamped together with the first clamping tooth group to form a double-sided clamping limit when the cable tie is used, so that the cable tie can be better and tighter in bundling materials, and the bottom of the anti-backward rod can be extended and retracted. After the cable tie is tied, the bottom of the anti-backward rod is pressed to a state of being clamped with the second clamping tooth group, and the limit gear is rotated so that the end face of the anti-backward rod abuts against the bottom face of the limit gear to form a limit, thereby keeping the anti-backward rod in an extended state, thereby improving the stability and practicality of the cable tie.
