Description

Technical Field

[0001] This utility model relates to the field of rigging technology, specifically to an anti-theft rigging. Background Technology

[0002] Chain locks are a common type of lock, often used for theft prevention of non-motorized vehicles such as bicycles and two-wheeled electric vehicles. They are used to secure bicycles and other non-motorized vehicles to railings, posts, or roadside trees.

[0003] Patent application number 201880080224.4 discloses a safety cable for securing a movable object, comprising three, four or more layers of fabric, braid, or woven material made of fibers or yarn, arranged in an overlapping manner, the safety cable having a chain as a core and a sheath, the chain being surrounded by composite filaments, yarns or twisted yarns, and a metal layer arranged between each layer of braid or woven material, the sheath comprising Teflon, acrylate and / or silicone.

[0004] The aforementioned safety ropes have the following drawbacks after being put into use: 1. They are not very theft-proof, as the core is a chain or anchor chain with large gaps between the links, making them relatively easy to break with a hacksaw or cable cutters; 2. They rely on multiple layers of high-strength textile materials to resist external shearing forces, such as Teflon, which are expensive, leading to a surge in production costs and a low cost-performance ratio. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an anti-theft rigging that improves the anti-theft rigging's resistance to damage, addressing the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-theft rigging, comprising an anti-theft rigging and a first rigging connector and a second rigging connector respectively disposed at both ends of the anti-theft rigging. The anti-theft rigging, from the outside to the inside, comprises a protective sleeve, a joint assembly, and a core component. The protective sleeve is fitted over the joint assembly, and the core component penetrates the joint assembly. The joint assembly comprises a plurality of alternately arranged first joint components and second joint components. Both the first joint components and the second joint components are hollow rotating bodies. Both axial ends of the first joint component are provided with arc-shaped concave surfaces, which form an arc-shaped cavity. Both axial ends of the second joint component are provided with bosses placed in the arc-shaped cavity. The outer peripheral surface of the boss is an outwardly protruding arc-shaped convex surface, and the boss can rotate omnidirectionally within the arc-shaped cavity.

[0007] The present invention, which has the above-mentioned features, uses a first joint and a second joint to replace the traditional chain. External cutting tools are difficult to get stuck between the arc-shaped convex and arc-shaped concave surfaces, eliminating the defect of excessive assembly gaps between chain links, improving the anti-theft rigging's resistance to damage while ensuring the rigging's flexible bending.

[0008] A further feature of this invention is that both axial ends of the joint assembly are first joint members, and one end of the first joint member located at the end cooperates with a second joint member, while the other end extends into the first cable connector or the second cable connector.

[0009] The present invention having the above features: the first joint member placed at the axial end of the joint assembly has one end inside the protective sleeve and the other end inside the cable connector. The first joint member passes through the connection between the cable connector and the protective sleeve, preventing the appearance of a gap that can be cut or sawed by external force due to accumulated tolerances at the connection, thereby improving the anti-theft rigging's shear and sawing resistance.

[0010] A further feature of this invention is that the first joint component is a cylindrical body, and the second joint component includes a cylindrical joint body and bosses disposed at both ends of the axial direction of the joint body. When the first joint component and the second joint component are engaged, the outer peripheral surface of the first joint component is flush with the outer peripheral surface of the joint body.

[0011] The present invention, which has the above-mentioned features, can ensure the accuracy of the shear force test data of the anti-theft rigging and improve the protection of the core component because the first joint is cylindrical; the outer diameter of the first joint component and the second joint component are the same, ensuring that the outer contour of the joint component is flat and fits evenly with the protective sleeve.

[0012] A further feature of this invention is that the first joint has arc-shaped lips at both ends, and an annular connecting line is formed where the arc-shaped concave surface meets the arc-shaped lip. The annular connecting line is always in contact with the arc-shaped convex surface, and a movable gap is left between the arc-shaped convex surface and the arc-shaped concave surface.

[0013] The present invention, which has the above-mentioned features, has the following characteristics: the annular connecting line is always in contact with the arc-shaped convex surface to ensure that the first joint and the second joint will not become loose; the arc-shaped convex surface and the arc-shaped concave surface adopt a point-to-surface contact method to reduce the contact area and improve the smoothness of the joint assembly's rotation; the movable gap between the arc-shaped convex surface and the arc-shaped concave surface can further improve the smoothness of the rotation of the first joint and the second joint, and ensure the flexibility of the rigging to bend at multiple angles.

[0014] A further feature of this invention is that: a first mounting hole extending axially is passed through the first joint member, a second mounting hole extending axially is passed through the second joint member, the first mounting hole and the second mounting hole are coaxial, and the core member passes through the first mounting hole and the second mounting hole.

[0015] The present invention having the above features: the first mounting hole and the second mounting hole are coaxially arranged to ensure smooth rotation of the first joint and the second joint; the first joint and the second joint are sequentially strung on the core member for easy installation.

[0016] A further feature of this invention is that the end face of the boss is a plane, and there is a gap between the end face of the boss and the first mounting hole.

[0017] The present invention having the above features: a gap is left between the boss and the first mounting hole to ensure that the boss will not collide or interfere with the opening of the first mounting hole when the joint assembly rotates in all directions.

[0018] A further feature of this invention is that the protective sleeve includes a woven layer and a rubber layer. The rubber layer is fitted over the joint assembly, and the woven layer is fitted over the rubber layer. The rubber layer extends from the front end of the joint assembly to the rear end of the joint assembly, and the woven layer extends from the front end of the rubber layer to the rear end of the rubber layer.

[0019] The present invention, which has the above-mentioned features, has a rubber layer attached to the outside of the joint assembly to protect the joint assembly, prevent the joint parts from rusting and prevent impurities from entering, and at the same time play a role in cushioning and shock absorption. The woven layer serves as the outer layer of the protective sleeve, which is wear-resistant and scratch-resistant, and provides protection for the rubber layer. The double-layer simple protective sleeve structure reduces production costs.

[0020] A further feature of this invention is that the first cable connector and the second cable connector have the same structure, both including a connecting terminal, a connecting tube, and a first connecting member or a second connecting member. The connecting tube is sleeved outside the connecting terminal, and the two are fixedly connected. One end of the connecting terminal is fixedly connected to the end of the core component, and the other end abuts against the end face of the first connecting member or the second connecting member. One end of the first connecting member or the second connecting member extends into the connecting tube, and the other end is located outside the connecting tube. The first connecting member or the second connecting member is fixedly connected to the connecting tube.

[0021] The present invention, which has the above-mentioned features, has the following characteristics: the first cable connector and the second cable connector have the same structure and interchangeable parts, which reduces production costs; the connecting tube is sleeved outside the connecting terminal, which protects the connecting terminal and is not easily damaged when subjected to violent attacks, thereby improving the structural reliability of the cable connector.

[0022] A further feature of this invention is that the end of the first connector located outside the connecting tube is a buttonhole, a pin, or a lock, and the end of the second connector located outside the connecting tube is a buttonhole, a pin, or a lock.

[0023] The present invention, which has the above-mentioned features, provides multiple ways to connect the two ends of the anti-theft rigging, and different combinations can be selected according to the actual situation.

[0024] A further feature of this invention is that the core component is a steel cable.

[0025] The present invention, which has the above-mentioned features, uses steel cable as the core component, which has high strength and flexibility, and is suitable for universal bending of joint components.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0035] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0036] like Figures 1-8 The anti-theft rigging shown includes an anti-theft rigging 1 and a first cable connector 2 and a second cable connector 3 respectively disposed at both ends of the anti-theft rigging 1. The anti-theft rigging 1 includes, from the outside to the inside, a protective sleeve 11, a joint assembly 12, and a core member 13. The core member 13 is preferably a steel cable. The protective sleeve 11 is sleeved on the joint assembly 12. The core member 13 passes through the joint assembly 12. The joint assembly 12 includes a plurality of alternately arranged first joint members 121 and second joint members 122. Both axial ends of the joint assembly 12 are first joint members 121. One end of the first joint member 121 located at the end cooperates with the second joint member 122, and the other end extends into the first cable connector 2 or the second cable connector 3.

[0037] Both the first joint 121 and the second joint 122 are hollow rotating bodies. Both ends of the first joint 121 are provided with arc-shaped concave surfaces 1211, which form an arc-shaped cavity 1212. Both ends of the second joint 122 are provided with bosses 1221 placed in the arc-shaped cavity 1212. The outer peripheral surface of the bosses 1221 is an outwardly protruding arc-shaped convex surface 12211, which can rotate in all directions within the arc-shaped cavity 1212.

[0038] The first joint member 121 is a cylindrical body, and the second joint member 122 includes a cylindrical joint body 1223 and bosses 1221 disposed at both ends of the joint body 1223 in the axial direction. When the first joint member 121 and the second joint member 122 are engaged, the outer peripheral surface of the first joint member 121 is flush with the outer peripheral surface of the joint body 1223. A first mounting hole 1215 extending in the axial direction passes through the first joint member 121, and a second mounting hole 1222 extending in the axial direction passes through the second joint member 122. The first mounting hole 1215 and the second mounting hole 1222 are coaxial. The core member 13 passes through the first mounting hole 1215 and the second mounting hole 1222. The first joint member 121 and the second joint member 122 are alternately strung on the core member 13.

[0039] The two ends of the joint assembly are placed in the first joint because: the first joint is cylindrical, preventing the shearing tool from slipping under shear force; the second joint, however, has protrusions at both ends with curved outer surfaces, causing the shearing tool to slip under shear force. This arrangement has two effects: 1. Facilitates shear force testing: the shearing tool used for testing can stably hold the first joint, improving testing accuracy; 2. Protects the steel cable: with one end of the first joint inside the protective sleeve and the other end inside the cable connector, the first joint passes through the connection between the cable connector and the protective sleeve, preventing gaps at the connection point from appearing due to accumulated tolerances, allowing for external shearing or sawing. If a thief forcibly cuts between the protective sleeve and the first / second cable connector, the shearing tool can only act outside the first joint. If the second joint were located at the end, the shearing tool would slip, sliding along the curved surface into the gap and cutting the steel cable, causing the joint assembly's protective function to fail. Therefore, both ends of the second joint need to be placed within the curved cavity of the first joint to improve the protective effect of the joint assembly.

[0040] like Figure 6 As shown, the first joint member 121 has arc-shaped lips 1213 at both ends. An annular connecting line 1214 is formed at the junction of the arc-shaped concave surface 1211 and the arc-shaped lip 1213. The annular connecting line 1214 is always in contact with the arc-shaped convex surface 12211. An movable gap 123 is left between the arc-shaped convex surface 12211 and the arc-shaped concave surface 1211. The end face of the boss 1221 is flat, and there is a gap between the end face of the boss 1221 and the first mounting hole 1215.

[0041] The protective sleeve 11 includes a braided layer 111 and a rubber layer 112. The rubber layer 112 is fitted over the joint assembly 12, and the braided layer 111 is fitted over the rubber layer 112. The rubber layer 112 extends from the first end of the joint assembly 12 to the last end of the joint assembly 12, and the braided layer 111 extends from the first end of the rubber layer 112 to the last end of the rubber layer 112. The rubber layer is preferably an NBR rubber tube.

[0042] The first cable connector 2 and the second cable connector 3 have the same structure, both including a connecting terminal 21, a connecting tube 22, and a first connector 23 or a second connector 24. The connecting tube 22 is sleeved outside the connecting terminal 21, and the two are fixedly connected. One end of the connecting terminal 21 is fixedly connected to the end of the core 13 by pressing, and the other end abuts against the end face of the first connector 23 or the second connector 24. One end of the first connector 23 or the second connector 24 extends into the connecting tube 22, and the other end is located outside the connecting tube 22. The first connector 23 or the second connector 24 is fixedly connected to the connecting tube 22. The connecting terminal 21 is fixedly connected to the core 13 by a pin 25. The first connector 23 is fixedly connected to the connecting tube 22 by a pin 25. The second connector 24 is also fixedly connected to the connecting tube 22 by a pin 25.

[0043] The first connector 23 has a buttonhole, pin, or lock at one end outside the connecting tube 22, and the second connector 24 has a buttonhole, pin, or lock at one end outside the connecting tube 22. The connector has the following implementation methods: Example 1: When the end of the first connector placed outside the connecting tube is set as a buttonhole and the end of the second connector placed outside the connecting tube is also set as a buttonhole, one buttonhole is a large buttonhole and the other is a small buttonhole. After passing the small buttonhole through the large buttonhole, it needs to be used with a lock.

[0044] Example 2: When the end of the first connector outside the connecting tube is set as a pin, the end of the second connector outside the connecting tube is set as a lock, and the pin is directly inserted into the lock. Alternatively, the end of the first connector outside the connecting tube can be set as a lock, and the end of the second connector outside the connecting tube can be set as a pin.

[0045] Example 3: When the end of the first connector outside the connecting tube is set as a pin, and the end of the second connector outside the connecting tube is set as a buttonhole, the pin needs to be used with a lock after passing through the buttonhole. Alternatively, the end of the first connector outside the connecting tube can be set as a buttonhole, and the end of the second connector outside the connecting tube can be set as a pin. Only Example 1 is shown in the accompanying drawings; Examples 2 and 3 are not shown.
