Description

Technical Field

[0001] This utility model relates to the field of modern law enforcement technology, and in particular to a reusable multi-ring plastic shackle. Background Technology

[0002] Plastic handcuffs have become a common choice in law enforcement equipment due to their low cost, ease of large-scale procurement and deployment, and significant advantages such as small size, light weight, and easy portability. They have been widely used in many law enforcement processes, including grassroots law enforcement, patrol and prevention, and emergency response.

[0003] However, traditional plastic handcuffs mostly use a single-ring structure, which has many drawbacks. On the one hand, single-ring plastic handcuffs have low tensile strength. When faced with a strong suspect, the suspect can break free of the handcuffs with external force, leading to escape incidents and posing a great safety hazard to law enforcement work, seriously affecting the effectiveness and safety of law enforcement. On the other hand, traditional plastic handcuffs are disposable products that need to be cut with scissors after use. This usage not only causes a lot of waste of resources, but also the discarded plastic handcuffs are difficult to degrade, causing serious environmental pollution, which is inconsistent with the concept of sustainable development. Therefore, we need to upgrade and transform existing technologies to overcome existing problems and shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a reusable multi-ring plastic binding tool to solve the problems mentioned in the background art.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown in Figure 4, this embodiment provides a reusable multi-ring plastic shackle, including a plastic toothed band 1, a lock chamber 2, a pull ring 3, and a key 4. The plastic toothed band 1 is bent into a ring by multiple outer teeth 11 on the band body. The upper ends of the two sets of plastic toothed bands 1 are connected to the pull rings 3. The lower end of the key 4 is provided with a key tongue 41. The key 4 and the key tongue 41 are inserted into the lock chamber 2.

[0026] In this embodiment, the lock chamber 2 is provided with a strap hole 21 and a keyhole 22. An inner locking plate 23 is slidably disposed inside the lock chamber 2. A return spring 26 is provided on the outer side of the inner locking plate 23, and the other end of the return spring 26 is connected to the inner wall of the lock chamber 2. An upper protrusion 24 is fixed on the upper end of the inner locking plate 23. One end of the plastic toothed band 1 passes through the strap hole 21 and meshes with the teeth of the inner locking plate 23. Two sets of positioning shafts 25 are fixed inside the lock chamber 2. The positioning shafts 25 pass through the lower end of the inner locking plate 23 and are connected to the return spring 26. The shape of the keyhole 22 is adapted to the shape of the key 4, and the inner wall of the keyhole 22 is provided with anti-slip texture. The outer teeth 11 on the surface of the plastic toothed band 1 and the teeth on the inner locking plate 23 are all... The handcuff is designed with an inclined structure and the outer locking teeth 11 and the inner locking plate 23 facing each other. The ends of the outer locking teeth 11 are designed with rounded chamfers. The plastic toothed band 1 is driven by the pull ring 3 to pass through the through hole 21 of the lock chamber 2, so that the outer locking teeth 11 and the teeth of the inner locking plate 23 are engaged. Under the action of the return spring 26, the teeth of the inner locking plate 23 tightly lock the outer locking teeth 11, which can achieve efficient and reliable binding and unlocking functions. It is convenient to quickly and smoothly engage the plastic toothed band 1, while preventing accidental loosening during use, enhancing the stability and safety of the binding. It can control the movement of the inner locking plate 23 precisely and stably during tightening and unlocking, and can automatically reset, ensuring the reusability of the handcuffs.

[0027] In this embodiment, a connecting rod 31 is fixed at the lower end of the pull ring 3, and limit buckles 32 are provided at both ends of the connecting rod 31. The upper end of the plastic toothed belt 1 is provided with a mounting hole 12, and the limit buckle 32 is inserted into the mounting hole 12. The pull ring 3 can be disassembled and assembled by the cooperation of the limit buckle 32 and the mounting hole 12. The pull ring 3 can pull the two sets of plastic toothed belts 1 synchronously, which makes it convenient for users to directly perform synchronous contraction and locking operations on both sides of the toothed belt, saving time and effort.

[0028] In this embodiment, the key tongue 41 is inserted into the lock chamber 2. The key tongue 41 can rotate and fit against the inner side of the upper protrusion 24. The handle surface of the key 4 is provided with anti-slip texture, and the anti-slip texture adopts a wave-shaped design with alternating concave and convex shapes. By rotating the key tongue 41, the upper protrusion 24 and the inner locking plate 23 are pushed to move on the positioning shaft 25. The inner locking plate 23 compresses the reset spring 26 to contract and the inner locking teeth disengage from the outer locking teeth 11. This enables movement control of the inner locking plate 23, which facilitates quick unlocking operations. It allows law enforcement officers to move the inner locking plate 23 smoothly with less force during emergency unlocking operations, avoiding delays in unlocking due to inconvenient operation.

[0029] The working principle and process of this utility model are as follows: When the plastic handcuffs are needed, pull the pull ring 3 to drive the plastic toothed band 1 through the through hole 21 of the lock chamber 2. Since the outer teeth 11 on the surface of the plastic toothed band 1 and the teeth on the inner locking plate 23 are both inclined structures and facing each other, the rounded chamfer structure at the end of the outer teeth 11 allows the toothed band to smoothly engage with the teeth on the inner locking plate 23 when passing through the through hole 21. As the toothed band is continuously pulled, the inner locking plate 23, pushed by the toothed band, overcomes the elastic force of the return spring 26 and slides along the positioning shaft 25 inside the lock chamber 2. The upper protrusion 24 moves accordingly. When the appropriate binding tightness is reached, stop pulling, and the return spring 26... Under the action of the mechanism, the inner locking plate 23 resets, and the teeth on the inner locking plate 23 tightly lock the outer locking teeth 11 of the plastic toothed band 1, thereby tightening and fixing the handcuffs and restraining the object. When it is necessary to unlock the handcuffs, the key 4 is inserted into the matching keyhole 22. The anti-slip texture on the inner wall of the keyhole 22 ensures that the key 4 is stable and does not slip when inserted. After insertion, by rotating the key 4, the key tongue 41 moves the upper protrusion 24 on the inner locking plate 23, causing the inner locking plate 23 to slide again against the elastic force of the reset spring 26, releasing the engagement of the teeth of the inner locking plate 23 with the outer locking teeth 11 of the plastic toothed band 1. At this time, the pull ring 3 can be easily pulled to pull the plastic toothed band 1 out of the lock chamber 2, completing the unlocking.
