Abstract
Description
Technical Field
[0001] This invention relates to the field of binding tools, specifically to a cable tie and a sealing strip. Background Technology
[0002] Cable ties, as a common bundling tool, are widely used in scenarios such as wire harness organization, item securing, and packaging sealing. Currently, the most widely used cable ties are disposable self-locking plastic ties. Their typical structure includes a ties body and a locking head at one end. The locking head usually contains a locking tongue, and the ties body has evenly spaced teeth along its length. In use, the ties are passed through the locking head and pulled tight. The locking tongue and the teeth of the ties engage in a one-way engagement, ensuring the ties can only tighten and cannot loosen. While this one-way locking characteristic ensures the reliability and convenience of bundling, it also directly results in the ties not being able to unlock actively; that is, the ties must be forcibly broken to be released, causing them to be discarded after a single use. When it is necessary to disassemble or adjust the bundled items, such as in data center cabling, engineering installation and commissioning, or temporary bundling, each operation requires cutting the old ties and replacing them with new ones. This is not only cumbersome and inefficient but also generates a large amount of plastic waste, causing material waste and environmental burden. Summary of the Invention
[0003] The purpose of this invention is to provide a cable tie that can be unlocked without damaging the fixing strap body, thus enabling recycling.
[0004] Another objective of this invention is to provide a seal that satisfies theft prevention while also being recyclable.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] A cable tie has a through lock hole in the lock head for inserting a cable tie. One end of the cable tie is connected to the lock head. Teeth are spaced along the length of one side of the cable tie. A latch is provided on the first wall of the lock hole, engaging with a groove between adjacent teeth. An insert plate is provided between the opposite side of the teeth on the cable tie and the second wall of the lock hole. The first and second walls are opposite to each other. The sum of the thickness H1 of the cable tie at the tooth tip and the thickness H2 of the insert plate is greater than the distance H between the latch tip and the second wall. The thickness H1 of the cable tie at the tooth tip is less than the distance H between the latch tip and the second wall. A handle plate for easy gripping is connected to the plate surface or edge outside the lock hole.
[0007] A seal includes the aforementioned cable tie, wherein the handle and the handle plate of the cable tie are provided with a sealing strip that wraps the two together.
[0008] The cable tie of this invention mainly uses an insert plate between the back of the fixing band and the first hole wall of the lock hole. The sum of the thickness of the fixing band at the top of the locking teeth and the thickness of the insert plate is greater than the distance between the tongue end of the lock tongue and the second hole wall, so that the locking teeth and the lock tongue form a one-way engagement, allowing the cable tie to tighten only in one direction. When unlocking is required, the insert plate can be removed from the lock hole by using the handle plate to release the engagement between the locking teeth and the lock tongue, thus loosening the cable tie without cutting the fixing band.
[0009] The seal of this invention mainly uses a sealing tape to wrap the handle and the plate of the cable tie together, so that when the operator unlocks the seal, the integrity of the sealing tape will be destroyed, thus satisfying the basic function of anti-theft. When sealing the next item, only a new sealing tape needs to be wrapped to reuse the seal. The cable tie itself can still be recycled, saving material costs. Attached Figure Description

[0015] Figure 8 This is a schematic diagram of the seal. Detailed Implementation
[0016] See Figures 1-7The cable tie shown has a through lock hole 11 in the lock head 10 for inserting the fixing strap 20. One end of the fixing strap 20 is connected to the lock head 10. On one side of the fixing strap 20, there are spaced teeth 21 along its length. The first hole wall 111 of the lock hole 11 has a locking tongue 12 that engages with the grooves 22 between adjacent teeth 21. An insert plate 30 is provided between the opposite side of the fixing strap 20 with the teeth 21 and the second hole wall 112 of the lock hole 11. Wall 111 and second hole wall 112 are opposite hole walls. The sum of the thickness H1 of the fixing band 20 at the tooth tip of the locking tooth 21 and the thickness H2 of the insert plate 30 is greater than the distance H between the tongue tip of the locking tongue 12 and the second hole wall 112. The thickness H1 of the fixing band 20 at the tooth tip of the locking tooth 21 is less than the distance H between the tongue tip of the locking tongue 12 and the second hole wall 112. The insert plate 30 has a handle plate 31 for easy gripping on the plate surface or edge outside the lock hole 11.
[0017] In the above scheme, the cable ties are typically made of plastic. Before binding the materials, the fixing strap 20 is located outside the locking hole 11, with its body in a flat position. When binding the materials, the overhanging end of the fixing strap 20 is inserted into the locking hole 11 so that the locking tongue 12 is embedded in the slot 22. The binding part of the materials is located within the closed loop formed by the body of the fixing strap 20. Figure 3 , Figure 4 Taking the position of the cable tie shown as an example, for ease of description, the overhanging end of the fixing band 20 is defined as the front end. The tooth surface of the locking tooth 21 that meshes with the locking tongue 12 is inclined upward from front to back. Since the sum of the thickness H1 of the fixing band 20 at the tooth tip position of the locking tooth 21 and the thickness H2 of the insert plate 30 is greater than the distance H between the tongue tip of the locking tongue 12 and the second hole wall 112, the tongue tip here refers to the closest end of the locking tongue 12 to the second hole wall 112. When the locking tongue 12 is embedded in the slot 22 and the fixing band 20 has a tendency to move backward out of the lock hole 11, the front end of the locking tongue 12 abuts against the rear groove wall of the slot 22, so that the cable tie can only be tightened and cannot be loosened. When it is necessary to release the binding state, the insert plate 30 can be removed from the lock hole 11 by using the handle plate 31 to unlock. Since the thickness H1 of the fixing band 20 at the tooth tip of the locking tooth 21 is less than the distance H between the tongue end of the locking tongue 12 and the second hole wall 112, the fixing band 20 can be easily pulled out from the lock hole 11.
[0018] To facilitate positioning and maintain the position of the insert plate 30 within the lock hole 11, a handle 40 is fixedly connected to the lock head 10. A protruding claw 32 is provided on the surface of the handle plate 31, and the claw 32 engages with the locking interface 41 on the handle 40. When the claw 32 engages with the locking interface 41, the insert plate 30 is located within the lock hole 11 and abuts against the second hole wall 112; when the claw 32 disengages from the locking interface 41, the insert plate 30 simultaneously disengages from the lock hole 11.
[0019] A more specific design involves placing the handle 40 and the fixing strap 20 on opposite sides of the lock head 10. The end of the handle plate 31 furthest from the insert plate 30 is flexibly connected to the end of the handle 40 furthest from the lock head 10. The surface of the handle plate 31 is perpendicular to the insert plate 30, and the surface of the handle 40 is perpendicular to the insertion direction of the lock hole 11. The handle plate 31 and the handle 40 are integrated, mitigating the risk of the handle plate 31 being lost. When the handle plate 31 and the handle 40 are engaged, both surfaces are perpendicular to the insertion direction of the lock hole 11, making gripping more convenient.
[0020] Preferably, the locking interface 41 is arranged on the handle 40 near the lock head 10, so that the operator can release the locking state between the handle plate 31 and the handle 40 with one hand when holding the handle 40.
[0021] Preferably, the connection between the insert plate 30 and the handle plate 31 is located at the insertion end of the lock hole 11. When the cable tie is tightened, i.e., when the fixing strap 20 moves in the insertion direction within the lock hole 11, the sliding friction generated between the fixing strap 20 and the insert plate 30 drives the handle plate 31 to fit more tightly against the grip 40, avoiding the risk of the insert plate 30 dislodging from the lock hole 11. Conversely, when the fixing strap 20 tends to move backward out of the lock hole 11, the foremost tip of the latch 12 abuts against the rear groove wall of the slot 22, blocking the displacement of the fixing strap and preventing any impact on the engagement state between the handle plate 31 and the grip 40.
[0022] More specifically, the card interface 41 is a circular through hole, and the card claw 32 includes card claw units 321 arranged at intervals along the circumference of the card interface 41. When the card claw 32 engages with the card interface 41, the hook at the outer edge of the card claw unit 321 hooks onto the inner edge of the card interface 41. At least two card claw units 321 are provided, preferably four.
[0023] To ensure a tighter fit between the grip 40 and the handle plate 31 when they are engaged, the grip 40 is provided with an auxiliary locking hole 42 and a positioning hole 43 on the plate between the tail end of the handle plate 31 and the locking interface 41. The auxiliary locking hole 42 and the positioning hole 43 are arranged alternately along the length of the grip 40. The handle plate 31 is provided with an auxiliary locking claw 33 and a positioning protrusion 34 that cooperate with the auxiliary locking hole 42 and the positioning hole 43, respectively.
[0024] See Figure 8 The seal shown includes the aforementioned cable tie, with a sealing tape 50 integrally wrapped around the handle 40 and the handle plate 31 of the cable tie. In this design, because the sealing tape 50 integrally wraps the handle 40 and the handle plate 31, the operator will inevitably damage the integrity of the sealing tape 50 when unlocking the seal, thus fulfilling the basic anti-theft function of the seal. When sealing the next item, only a new sealing tape 50 needs to be wrapped, allowing the seal to be reused. The cable tie itself can still be recycled, saving material costs.
[0025] Furthermore, if the sealing tape 50 is wrapped around the grip 40 away from the lock head 10, the operator can use the elastic deformation capability of the handle plate 31 to pry the end of the handle plate 31 near the lock head 10 to disengage the insert plate 30 from the keyhole 11 without damaging the sealing tape 50. Therefore, to avoid the above situation, the sealing tape 50 is preferably arranged near the lock head 10, or both the grip 40 and the handle plate 31 are made of rigid materials.
[0026] To further ensure the anti-theft capability of the sealing strip 50, as a preferred embodiment, the strip surface of the sealing strip 50 simultaneously covers the interlocking card interface 41 and card claw 32. Another preferred embodiment is that the strip surface of the sealing strip 50 is located between the lock head 10 and the card interface 41.
[0027] Preferably, the sealing strip 50 is made of paper, which facilitates normal unlocking of the seal and is inexpensive.
