[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0025] Directional terms mentioned in this invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "side", "top" and "bottom", are only used with reference to the directions of the drawings. The directional terms used are used to illustrate and understand the invention, and are not intended to limit the invention.

[0026] The terms "first" and "second" in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor as limiting the order of precedence.

[0027] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] Referring to Figures 1, 2, 3, and 4, the present invention provides a double-sided toothed cable tie, comprising a connected head 1 and a strap body 2. The strap body 2 includes opposing first and second sides 22 and 24, each of which is provided with first serrations 21. The head 1 is provided with a cavity 11, within which are disposed two opposing connecting portions 12. Opposite surfaces of the two connecting portions 12 are provided with second serrations 121. The strap body 2 can be selectively positioned between the two connecting portions 12. When the strap body 2 is positioned between the two connecting portions 12, the first serrations 21 engage with the second serrations 121. The combination of the two sets of first and second serrations 21 and 121 allows the cable tie to withstand greater tensile forces, doubling its tensile strength and making it less susceptible to breakage. Furthermore, the tensile forces applied to the cable tie are borne by the two first serrations 21, distributing the forces and reducing the force applied to each first serration 21 by half. This makes the first serrations 21 less susceptible to breakage and enhances the durability of the cable tie. When the cable tie is pulled hard, the strap body 2 is not easily dislodged from the cavity 11 under the restriction of the double-sided first serrations 21 , so that the cable tie is not easily unhooked and slipped off.

[0029] 5 , the first serrations 21 on the first side 22 and the first serrations 21 on the second side 24 are staggered. Correspondingly, the two rows of second serrations 121 are staggered. The portion between the two rows of first serrations 21 can be made thicker, making the structure more robust and preventing the belt 2 from breaking.

[0030] There are multiple gaps 211 between the first serrations 21 on the first side 22. The multiple gaps 211 are respectively arranged opposite to the first serrations 21 on the second side 24. In the length direction of the belt body 2, the minimum size L1 of the gaps 211 is less than or equal to the size L2 of the first serrations 21 on the second side 24. The first serrations 21 are arranged larger than the gaps 211, further strengthening the structural strength of the belt body 2.

[0031] In this embodiment, in the length direction of the belt body 2, the size L2 of the first serration 21 is greater than or equal to the offset distance L3 between the first serration 21 on the first side 22 and the first serration 21 on the second side 24. The first serrations 21 on both sides are arranged more densely, further strengthening the clamping strength between the belt body 2 and the head 1.

[0032] A first groove 25 is provided on the surface of the belt body 2 located on the first side 22 and the surface located on the second side 24. The first serration 21 is located in the first groove 25. The first groove 25 includes an inner wall 251, and the first serration 21 is connected to the inner wall 251. The inner wall 251 can provide support for the first serration 21 and can enhance the structural strength of the belt body 2.

[0033] The top 26 of the first serration 21 located on the first side 22 is flush with the surface of the belt body 2 located on the first side 22, and the top 26 of the first serration 21 located on the second side 24 is flush with the surface of the belt body 2 located on the second side 24. The top 26 is the tip of the first serration 21, which greatly reduces the possibility of bending and damage of the first serration 21 and improves the reliability of the first serration 21.

[0034] A guide belt 23 is provided at the end of the belt body 2 opposite to the head 1. The thickness of the guide belt 23 is less than that of the belt body 2, which facilitates the placement of the guide belt 23 into the cavity 11. The end of the guide belt 23 opposite to the belt body 2 is set to a pointed end. The guide belt 23 is more pointed, which facilitates its flexible placement into the cavity 11 and is convenient for use.

[0035] The two ends of the cavity 11 are respectively an inlet end 111 and an outlet end 112. The inlet end 111 includes an end face 114. The head 1 includes an outer wall 13. The belt body 2 is connected to the connection between the end face 114 and the outer wall 13. The belt body 2 is closer to the inlet end 111, which facilitates the insertion of the belt body 2 from the inlet end 111.

[0036] The cavity 11 includes a cavity wall 115, and the two connecting parts 12 are both strip-shaped, one end of which is connected to the cavity wall 115, and the other end is suspended in the cavity 11. In the arrangement direction of the inlet end 111 and the outlet end 112, and toward the outlet end 112, the gap between the two connecting parts 12 gradually becomes smaller, so that the closer to the outlet end 112, the tighter the connection between the two connecting parts 12 and the belt body 2, further preventing the belt body 2 from escaping from the cavity 11.

[0037] Two notches 113 are arranged opposite to each other in the cavity 11 . The arrangement direction of the two notches 113 is parallel to the width direction of the belt body 2 . In the width direction of the belt body 2 , the size of the cavity 11 is larger, which further facilitates the placement of the belt body 2 into the cavity 11 .

[0038] The belt body 2 and the head 1 are integrally formed, and the connection between the two is more solid, which prevents the belt body 2 and the head 1 from being separated due to excessive tension, making the cable tie stronger and more durable.

[0039] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
