Description

Technical Field

[0001] This invention relates to the field of anti-theft and anti-tamper fastener technology, specifically to a flexible connection anti-tamper component and its dedicated housing and assembly method, applicable to various application scenarios that use rope-like or strip-like flexible connectors, such as logistics seals, security equipment, bag locks, and anti-theft binding of goods, and need to achieve anti-illegal disassembly, anti-replacement and anti-process circumvention. Background Technology

[0002] Currently, the anti-tamper locking structures for flexible connectors 6 on the market generally adopt simple combination methods, with only three mainstream solutions: the first is a combination structure of flexible connector 6 alone with locking and fixing parts 3; the second is a combination structure of flexible connector 6, anti-pry pads, and locking and fixing parts 3; and the third is a combination structure of flexible connector 6 with both ends directly glued together.

[0003] All three types of existing structures have core defects, poor overall protection performance, and cannot effectively prevent theft and tampering. Existing technologies can only achieve basic locking and fixing functions, and do not have a dedicated protective structure for the locking area formed by the flexible connector 6 and the locking fixing part 3. The locking area is mostly directly exposed to the external environment, and fixation is achieved solely by the interlocking and bonding of the parts, without any isolation or anti-pry protection design.

[0004] Malicious disassembly can be achieved by using external equipment such as adhesive removers, small pry tools, and pulling tools to directly insert into the locking area, disrupting the interlocking relationship between the flexible connector 6 and the locking and fixing part 3, thus achieving non-destructive disassembly. Furthermore, the structure can be quickly restored after disassembly, and the disassembly marks are concealed, making it difficult for ordinary goods sellers to identify whether their goods have been tampered with or disassembled, easily leading to economic losses.

[0005] Meanwhile, simple disassembly methods for this type of traditional structure have been widely disseminated on online platforms such as Douyin, Xiaohongshu, WeChat groups, and Bilibili, further weakening the protective effect of traditional anti-tampering solutions and making the pain points of industry use increasingly apparent. Summary of the Invention

[0006] Purpose of the invention To address the shortcomings of existing technologies, such as lack of protection, ease of disassembly, reversibility, low cost of circumvention, and concealed protective traces, this invention provides a flexible connection anti-tamper component, its housing, and assembly method. Utilizing the deformable nature of the flexible connector 6, combined with a rear-mounted fully enclosed limiting zone 2 protective structure, a mid-section ejector component 4 bending and circuit-breaking structure, and a front-section size-limiting opening design, multiple physical anti-tamper barriers are constructed. Simultaneously, a dedicated standardized assembly process solidifies the irregularly shaped bending protective structure, eliminating issues of process avoidance and structural replication, significantly improving the anti-tamper level, completely blocking the disassembly path of external tools, eliminating the problems of non-destructive disassembly and concealed restoration, and protecting the safety of goods. Technical solution

[0007] To achieve the above objectives, the present invention adopts the following technical solution: 1. A flexible connection anti-tampering component, comprising: a first body 1, a limiting area 2, a locking and fixing part 3, an ejection part 4, a second body 5, and a flexible connector 6; The first body 1 and the second body 5 are rigid shell structures that can be interlocked. The shell has at least one front opening. The outline size of the front opening is smaller than the outline size of the locking and fixing part 3 and larger than the outline size of the flexible connector 6. The limiting area 2 is located at the rear assembly end inside the first body 1 and the second body 5. The internal gap of the limiting area 2 is smaller than the outline size of the locking and fixing part 3. The internal outline of the limiting area 2 is precisely matched with the external outline of the locking and fixing part 3, which can limit the radial and axial displacement of the locking and fixing part 3. It is used to place and completely cover the locking area formed by the flexible connector 6 and the locking and fixing part 3, and to limit the displacement and disengagement of the locking and fixing part 3. The locking and fixing part 3 is an anti-loosening snap-fit ​​part, used to assemble and fix the rope-shaped or strip-shaped deformable flexible connector 6. The flexible connector 6 body has at least one assembly hole so that the locking and fixing part 3 can be snapped and fixed to form a locking area. The ejector component 4 is a fixed solid structure, located inside the first main body 1 and the second main body 5 and in front of the opening of the limiting area 2. The overall outline of the ejector component 4 does not exceed the internal space of the shell, completely blocking the straight path from the front opening of the shell to the rear opening of the limiting area 2. After the first main body 1 and the second main body 5 are engaged to form a closed shell, the push-out component 4 pushes the extension of the flexible connector 6 outside the locking area, causing the flexible connector 6 to bend irregularly and break the straight layout. The bent extension of the flexible connector 6 extends out from the opening at the front of the shell. Through the structural cooperation, the straight path of external objects extending into the locking area from the opening is completely blocked, protecting the weak connection between the flexible connector 6 and the locking and fixing part 3, and preventing illegal prying and disassembly.

[0008] 2. A housing structure for the flexible connection anti-disassembly assembly of claim 1, characterized in that it includes a first main body 1 and a second main body 5 that engage with each other, wherein the first main body 1 and the second main body 5 are rigid semi-enclosed housing structures, and the two are closed together to form a complete closed housing; The housing defines a rear limiting area 2 and a middle ejection component 4 assembly space, which can completely cover the limiting area 2, the locking and fixing part 3, the ejection component 4, and the locking area formed by the flexible connector 6 and the locking and fixing part 3. The housing has a front opening through which the flexible connector 6 passes. The outline size of the front opening is smaller than that of the locking and fixing part 3 and larger than that of the flexible connector 6. The ejector part 4 is fixed in the middle of the housing and can press the flexible connector 6 to form an irregular bending structure, blocking the straight path of external objects extending into the locking area through the housing opening, thereby achieving anti-disassembly protection of the locking connection position.

[0009] 3. An assembly method for the flexible connection anti-tamper assembly of claim 1, characterized in that it includes the following steps: Step 1: Secure the locking and fixing part 3 to the flexible connector 6 with the assembly hole so that the two cooperate to form a stable locking area; Step 2: Place the formed locking area into the rear limiting area 2 inside the first main body 1 or the second main body 5 for precise positioning, and use the adapting structure of the limiting area 2 to restrict the displacement of the locking and fixing parts 3. Step 3: Relying on the ejector component 4 in the middle section of the shell, push the extension of the flexible connector 6 on the outside of the locking area, forcing the flexible connector 6 to bend and deform irregularly inside the shell, completely blocking the straight connection channel from the front opening of the shell to the rear limiting area 2. Step 4: Extend the flexible connector 6, which has been bent and positioned, outward from the front opening of the shell. Step 5: Align and snap together the first main body 1 and the second main body 5 to form a complete closed shell, so that the internal structure of the shell completely covers the locking area, the ejector component 4 and the limiting area 2, and complete the assembly of the overall anti-disassembly component.

[0010] 4. The shell structure of the flexible connection anti-tampering component according to claim 2, characterized in that a disposable anti-restore component with a unique anti-counterfeiting mark is affixed to the splicing gap between the first main body 1 and the second main body 5. The anti-restore component cannot be restored after being damaged, and the shell can be directly identified as to whether it has been illegally opened. Beneficial effects

[0011] Compared with the prior art, the present invention has the following beneficial effects: First, this invention abandons the traditional exposed locking structure and adopts a split rigid shell with a rear-mounted fully enclosed limiting area 2. The limiting area 2 is precisely matched with the contour of the locking and fixing part 3, which can restrict the multi-directional displacement of the part and completely seal and isolate the core locking area. This completely solves the defects of the existing technology where the locking area is exposed and easily pried and disassembled by tools. It structurally protects the weak locking position of the flexible connector 6, and greatly improves the basic anti-theft protection performance.

[0012] Secondly, the present invention provides an ejector component 4 in the middle section of the shell, and uses the deformable characteristics of the flexible connector 6 to force the flexible connector 6 to form an irregular bend, completely destroying the straight insertion channel from the opening to the locking area, eliminating the tool-free force path, and preventing conventional prying and glue removal disassembly methods. The physical anti-disassembly barrier is tight, and conventional disassembly methods are ineffective.

[0013] Third, the present invention adopts a front opening design with differentiated size, which not only meets the normal installation requirements of the flexible connector 6, but also prevents the locking and fixing parts 3 from coming out, while isolating large-sized disassembly tools from entering, forming a multi-layer physical protection structure with strict protection logic and strong structural stability.

[0014] Fourth, this invention features a one-time anti-counterfeiting and anti-replica component. Illegal opening and disassembly will cause irreversible damage, making it impossible to restore the disguise. This allows for quick verification of signs of disassembly and substitution of goods, effectively avoiding economic losses and making traceability and verification convenient and efficient.

[0015] Fifth, this invention features a unique and exclusive fixed-shape assembly process that strictly follows the exclusive process logic of "first locking and forming, then limiting and positioning, then bending and breaking the circuit, and finally sealing and covering". This can stably solidify the core anti-disassembly structure of irregularly shaped bends, completely solving the industry pain point that traditional structures can easily circumvent the protective effect by changing the assembly process and adjusting the penetration path. It constructs a protective system from the dual dimensions of product structure and assembly process, with extremely strong anti-evasion capabilities.

[0016] Sixth, the process sequence of this invention is deeply integrated with the anti-tampering effect. The exclusive bending process can permanently fix the bending shape of the flexible connector 6, making the structure more stable. It will not lose its anti-tampering ability due to loosening or repositioning, which greatly improves the product's durability and protective stability. Compared with the traditional structure of random insertion and assembly, the protection level is significantly improved.

[0017] Seventh, the present invention has a simple structure and is highly adaptable. It can be adapted to various structural forms such as through-wear, single-wear, and wrap-around according to the usage scenario. It does not require modification of the core anti-disassembly principle and assembly logic of the first main body 1, the second main body 5, the limiting area 2, the locking and fixing parts 3, the ejection part 4, and the flexible connector 6. It is suitable for mass production and anti-theft binding needs in multiple scenarios and has a wide range of applications. Attached Figure Description

The components in the drawings are uniformly labeled as follows: 1-first main body, 2-limiting area, 3-locking and fixing part, 4-ejection part, 5-second main body, 6-flexible connector.

[0019] Figures 1 to 4 : Schematic diagrams of the through-type structure from various perspectives and exploded structural diagrams of the parts; Figures 5 to 8 : Schematic diagrams of the single-through structure from various perspectives and exploded structural diagrams of the parts; Figures 9 to 12 : These are schematic diagrams and structural assembly drawings of the wrap-around structure from various perspectives. Detailed Implementation

[0020] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention. Based on the embodiments of the present invention, all embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship of each component under the attitude of the attached drawings. If the actual attitude of the attached drawings changes, the directional indications will be adjusted accordingly.

[0022] In this invention, unless otherwise explicitly specified and limited, the terms "connection" and "fixation" should be interpreted broadly. For those skilled in the art, their conventional meanings can be understood according to the actual scenario, and are not limited to a single fixing method.

[0023] In this invention, the irregular bend is a multi-segment zigzag bend structure that is not right-angled and is an irregular arc. After bending, the extended section of the flexible connector 6 has an angle of 15°-75° with the central axis of the shell. Figures 1 to 4 As shown, this is the first embodiment of the present invention, which discloses a through-type flexible connection anti-tampering component.

[0024] In this embodiment, the flexible connector 6 is a deformable strip structure with pre-set mounting holes for assembling and fixing with the locking and fixing part 3. The locking and fixing part 3 is an anti-loosening snap-fit ​​structure with an interlocking structure on its inner side that adapts to the flexible strip connector 6, which can stably snap into the hole position of the flexible connector 6. The two work together to form a locking area that cannot be loosened on its own.

[0025] The first body 1 and the second body 5 are mutually matching, half-rigid shell structures that, when snapped together, form a complete closed cavity. The rear section of the cavity has a limiting area 2. The gap in the limiting area 2 is smaller than the contour of the locking and fixing part 3 and precisely fits it, fully covering the locking area and strictly limiting the radial and axial displacement and disengagement of the locking and fixing part 3, ensuring the stability of the locking structure. Symmetrical front openings are provided on both sides of the shell. The opening size is smaller than the contour of the locking and fixing part 3 but larger than the contour of the flexible connector 6, allowing the extension section of the flexible connector 6 to pass through while simultaneously preventing the locking and fixing part 3 from disengaging and large tools from entering.

[0026] The ejector component 4 is a fixed solid protrusion structure, integrally formed in the middle section of the shell, in front of the opening of the limiting area 2, and does not extend beyond the internal space of the shell. After the shell is closed, the ejector component 4 presses against the outer wall of the flexible connector 6, causing the flexible connector 6 on the outside of the locking area to form a stable irregular bend, completely cutting off the straight channel from the front opening of the shell to the rear limiting area 2, forming a physical barrier.

[0027] This embodiment employs a proprietary assembly process: First, the locking and fixing parts 3 and the flexible connectors 6 are snapped together and locked to form a stable locking area; then, the locking area is precisely positioned within the rear limiting area 2, using the limiting area 2 to restrict the displacement of the locking and fixing parts 3; subsequently, the internal ejector parts 4 push the flexible connectors 6 to form an irregular bend, permanently blocking the straight channel; then, the bent flexible connectors 6 are pushed out from the front openings on both sides; finally, the first main body 1 and the second main body 5 are snapped together and closed to solidify the overall anti-disassembly structure.

[0028] The anti-tampering principle of this embodiment is as follows: the locking area is completely enclosed by the rear limiting area 2, the locking and fixing parts 3 have no room for displacement or loosening, and the core engagement position cannot be touched from the outside; the flexible connecting part 6 with its bend in the middle completely blocks the path of tools, and small disassembly tools and adhesive removal equipment cannot access the internal locking structure, making it impossible to pry open and disassemble. At the same time, the exclusive and fixed assembly process solidifies the bending and breaking structure, and the protective effect cannot be circumvented by changing the assembly method or adjusting the wiring path. The disposable anti-restore parts in the shell gaps can intuitively identify traces of illegal opening, preventing concealed restoration.

[0029] like Figures 5 to 8 As shown, this is the second embodiment of the present invention, disclosing a single-through flexible connection anti-tampering component. The overall structure and core protection principle of this embodiment are consistent with the through-through structure, the only difference being that a front opening is provided on one side of the housing to adapt to narrow assembly scenarios with only one-sided wiring. The ejector component 4 in the middle section inside the housing is correspondingly and matched, stably pushing the single-sided flexible connector 6 to form an irregular bend, blocking the straight path from the single-sided opening to the rear limiting area 2. The protection effect is exactly the same as the through-through structure, and the assembly process and anti-tampering logic are completely identical.

[0030] like Figures 9 to 12 As shown, this is the third embodiment of the present invention, disclosing a wrap-around flexible connection anti-tampering component. The core structure of this embodiment is consistent with the previous embodiments, with the optimization being a larger full-coverage area of ​​the housing limiting region 2, which can comprehensively wrap the outer contour of the locking area, resulting in a higher level of protection. After the internal ejector component 4 pushes the flexible connector 6, the flexible connector 6 forms a winding irregular bend, further extending the tool insertion path and completely eliminating the possibility of the tool touching the locking area. This is suitable for usage scenarios with frequent vibrations and high protection requirements. The assembly process and anti-counterfeiting protection structure remain consistent with the previous embodiments.

[0031] This invention can flexibly adjust the shape of the first main body 1 and the second main body 5, the form of the ejector component 4, the type of the flexible connector 6 and the insertion method according to the actual use scenario and assembly space requirements, resulting in a variety of adaptable structural forms. The core anti-disassembly structure and assembly principle remain consistent, and the adaptability range is wide.

[0032] This invention utilizes a triple-structure synergy—a rear-mounted fully enclosed limiting zone 2, a mid-section ejector component 4 forcibly bending and breaking the circuit, and a front-section size-limiting opening—combined with a proprietary assembly process, to form a dual closed-loop anti-tamper system encompassing both structure and process. This completely cuts off paths to external disassembly, structural circumvention, and process replication. The proprietary assembly process permanently shapes the bending protective structure, significantly enhancing its protective stability and making it difficult to replicate or circumvent. Forced disassembly results in irreversible damage to both the shell structure and the anti-counterfeiting and anti-replication components, making it impossible to masquerade and restore. This effectively protects the safety of goods, demonstrating exceptional practicality, stability, and anti-circumvention capabilities.

[0033] The above description is merely a typical embodiment of the present invention and is not intended to limit the technical scope of the present invention. Any equivalent modifications or simple improvements made based on the technical solutions of the present invention shall fall within the protection scope of the present invention.
