Description

Technical Field

[0001] This utility model belongs to the field of cable tie technology, specifically relating to a high-strength plastic cable tie. Background Technology

[0002] Plastic cable ties are a convenient tool widely used for bundling, securing, and organizing cables or items. They mainly consist of two parts: the cable tie head and the cable tie strip. The cable tie head has a threading hole, through which the cable tie strip is securely locked to prevent loosening. They are characterized by their simple structure, ease of use, and low cost, and are typically made of high-strength nylon, offering good corrosion resistance and anti-aging properties. In some plastic cable tie designs, metal clips are used to lock the cable tie strip. These metal clips usually have a rectangular thin-plate structure, with one end inserted into the threading hole and the other end fixedly connected to the plastic cable tie head. However, this design has certain drawbacks in practical applications. The connection between the metal clip and the plastic cable tie head is relatively weak, resulting in poor securing. Under significant external force, the metal clip risks being pulled off the plastic cable tie head, thus affecting the lifespan and reliability of the plastic cable tie. Utility Model Content

[0003] In this regard, the present invention provides a high-strength plastic cable tie, which enhances its tensile strength and durability by optimizing the connection method between the card and the cable tie head.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides a high-strength plastic cable tie, including a cable tie head and a cable tie strip; the cable tie head is provided with a through hole for threading the cable tie strip and a locking piece for locking the cable tie strip; the locking piece is made of metal sheet, and the locking piece includes a fixing frame with a through hole and a card integrally connected to the fixing frame. The card is formed of the sheet at the through hole and is set at an angle to the fixing frame. The fixing frame is fixedly connected to the cable tie head, and the through hole allows the cable tie strip to pass through.

[0006] Preferably, a reinforcing rib is formed at the junction of the fixing frame and the card.

[0007] Preferably, the fixing frame is provided with a stamped protrusion, which is fixed inside the cable tie head.

[0008] Preferably, the end edge of the card is arranged along the width direction of the thread hole, and has protruding teeth spaced apart along its width direction.

[0009] Preferably, the cable tie has a reinforcing strip inside, and the reinforcing strip extends along the length of the cable tie.

[0010] Preferably, the cable tie head is provided with two threading holes, and the card and the threading hole are provided on the same locking piece at positions corresponding to the two threading holes.

[0011] Preferably, a support platform is provided inside the threading hole at the base of the card, and the support platform and the cable tie head are integrally formed.

[0012] Preferably, the surface of the cable tie head is provided with a locking hole at the position corresponding to the threading hole.

[0013] Preferably, the cable tie head has a protruding fixing head on its side, and the fixing head is provided with a fixing hole.

[0014] Preferably, the fixing head is provided around the cable tie head.

[0015] The positive effects of this invention are as follows: The plastic cable tie in this invention enhances its tensile strength and durability by optimizing the connection between the metal clip and the cable tie head. During use, after the cable tie passes through the threading hole and through-hole, it is more securely locked by the clip on the locking plate, effectively preventing the cable tie from slipping back or loosening, and significantly improving the reliability of the locking mechanism. Simultaneously, the fixed connection between the fixing frame and the cable tie head further enhances the overall structural strength and durability, fundamentally avoiding the problem of easy loosening of the metal locking plate in traditional designs, making it suitable for various high-intensity and frequently stressed applications.

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0024] The high-strength plastic cable tie structure of this utility model embodiment is as follows: Figures 1 to 4 As shown, it includes a cable tie head 1 and a cable tie strip 2; the cable tie head 1 is provided with a through hole 11 for threading the cable tie strip 2 and a locking piece 3 for locking the cable tie strip 2; the locking piece 3 is made of metal sheet, and the locking piece 3 includes a fixing frame 32 with a through hole 31 and a card 33 integrally connected to the fixing frame 32. The card 33 is formed from the sheet at the through hole 31 and is set at an angle with the fixing frame 32. The card 33 can be formed by stamping process; the fixing frame 32 is fixedly connected to the cable tie head 1 (injection molded integrally or...). (Assembly connection), the through hole 31 allows the cable tie 2 to pass through; during use, after the cable tie 2 passes through the through hole 11 and through hole 31, it is more firmly locked by the card 33 on the locking piece 3, effectively preventing the cable tie 2 from retracting or loosening, and significantly improving the reliability of locking; at the same time, the fixed connection between the fixing frame 32 and the cable tie head 1 further enhances the strength and durability of the overall structure, fundamentally avoiding the problem of easy loosening of metal locking pieces in traditional designs, and is suitable for various high-intensity and frequent stress occasions. Figure 1 The cable tie head 1 shown has two threading holes 11. In this example, the cable tie head 1 and the cable tie strip 2 are usually separate. The two ends of the cable tie strip 2 pass through the two threading holes 11 respectively for locking. Figure 4 The cable tie head 1 shown has only one threading hole 11. In this example, the cable tie head and the cable tie strip 2 are usually a single unit. Figure 1 and Figure 4 The middle arrow indicates the direction in which the cable tie 2 passes through the cable hole 11.

[0025] Furthermore, a reinforcing rib (not shown in the figure) is formed at the connection between the fixing frame 32 and the card 33; the reinforcing rib can be formed by stamping. The design of the reinforcing rib optimizes the structural stability of the locking piece 3, ensuring that the card 33 can always maintain a stable included angle, thereby improving the locking effect on the cable tie strip 2 and preventing the cable tie strip 2 from loosening or retracting due to external force.

[0026] like Figure 1 and Figure 4As shown, the fixing frame 32 is provided with a stamped protrusion 34, which is fixed inside the cable tie head 1. After assembly or injection molding, the protrusion 34 is fixed inside the cable tie head 1 along with the fixing frame 32. The protrusion 34 can strengthen the connection between the fixing frame 32 and the cable tie head 1, thereby improving the connection stability and ensuring that the locking piece 3 can remain firmly fixed when subjected to pulling or other external forces.

[0027] See Figure 3 The card 33 has an end edge along the width direction of the thread hole 11, and has protruding teeth 35 spaced apart along its width direction. When locking the cable tie 2, the protruding teeth 35 can efficiently penetrate into the cable tie 2 and form a firm engagement, which significantly improves the locking effect and prevents the cable tie 2 from sliding or coming off when subjected to force. The protruding teeth 35 can be designed into various shapes such as triangular teeth, trapezoidal teeth or semi-circular teeth according to actual needs.

[0028] See Figure 2 The cable tie 2 is provided with a reinforcing strip 21 inside, which extends along the length of the cable tie 2. The addition of the reinforcing strip 21 can effectively improve the structural strength of the cable tie 2, enabling it to withstand higher tensile forces and more complex external forces. It is particularly suitable for heavy-duty, high-strength or long-term use scenarios. The reinforcing strip 21 can be designed as a high-strength material such as metal wire (e.g., stainless steel wire) or high-strength glass fiber wire.

[0029] See Figure 1 As shown, when the cable tie head 1 is provided with two threading holes 11, the card 33 and the through hole 31 are provided on the same locking piece 3 at the positions corresponding to the two threading holes 11. This allows a single locking piece 3 to serve two threading holes 11 at the same time, reducing the number of locking pieces 3 and improving production efficiency and cost optimization.

[0030] Furthermore, a support platform 14 is provided inside the threading hole 11 at the root of the card 33. The support platform 14 is integrally formed with the cable tie head 1. The support platform 14 provides effective support for the card 33, enhances its resistance to deformation, thereby improving the locking effect of the cable tie strip 2, preventing the cable tie strip 2 from loosening or falling off, and making the overall structure more stable and reliable.

[0031] To enhance the mechanical properties of the locking plate 3, it is preferable that the locking plate 3 is made of stainless steel or iron sheet with a thickness of not less than 1.5mm; this further enhances its structural strength, enabling it to withstand high tensile forces and complex environmental conditions, preventing the locking plate 3 from deforming or breaking under stress, and ensuring the long-term reliability and safety of the cable tie.

[0032] Preferably, a locking hole 12 is provided on the surface of the cable tie head 1 at a position corresponding to the threading hole 11, specifically, the central axis of the locking hole 12 passes through the threading hole 11; the setting of the locking hole 12 can further expand the function of the cable tie. For example, in one usage scenario, after the cable tie is tightened, a self-tapping screw can be screwed into the locking hole 12 and inserted into the threading hole 11 to lock the cable tie strip 2, thereby strengthening the locking effect on the cable tie strip 2. In this application scenario, attention should be paid to selecting a self-tapping screw of appropriate specification to avoid excessive damage to the cable tie strip 2 by the self-tapping screw, which would affect the strength of the cable tie strip 2; in addition, in another usage scenario, a self-tapping screw can also be screwed into the locking hole 12 to fix a label, further improving the practicality of the cable tie.

[0033] In the preferred solution, see Figure 1 As shown, by designing a protruding fixing head 13 on the side of the cable tie head 1 and setting a fixing hole 131 on the fixing head 13, the user can use a screw to pass through the fixing hole 131 to firmly fix the cable tie to the target position, ensuring installation stability and reliability. Preferably, fixing heads 13 are set on all four sides of the cable tie head 1. This design greatly improves the flexibility and adaptability of installation. The user can select the most suitable fixing head 13 according to actual needs. Excess fixing heads 13 can be cut off when interference occurs, avoiding affecting the overall structure and use effect.

[0034] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this utility model.
