Description

Technical Field

[0001] This utility model belongs to the technical field of daily necessities and auxiliary tools, specifically an adjustable rubber lanyard. Background Technology

[0002] In daily life, lanyards are a common accessory used for carrying and securing items such as keys, name tags, and outdoor gear. Most lanyards on the market currently use a fixed length design or a simple adjustment mechanism, such as using a slip clip or knot to adjust the length. However, these methods have certain limitations in practical use, such as insufficient flexibility in adjustment, susceptibility to loosening or damage, and potential wear and tear leading to malfunction after prolonged use. Furthermore, traditional lanyards are mostly made of fiber or plastic, whose durability and comfort are insufficient in certain situations.

[0003] For example, existing lanyards are typically made of woven fibers and equipped with metal or plastic adjusting parts. Their specifications disclose that they include a rope body with connectors fixed to both ends. Each connector has an adjusting buckle, which uses friction to fix the rope's position, thus adjusting the length. However, this design is prone to failure due to weakened friction during frequent use, and its adjustment precision is low, making it difficult to meet users' personalized length needs. The above demonstrates the shortcomings of existing technology.

[0004] Therefore, we made improvements by proposing an adjustable rubber lanyard. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing hanging ropes being inflexible in adjustment, prone to loosening or damage, and potentially malfunctioning due to wear and tear after prolonged use.

[0006] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides an adjustable rubber lanyard, comprising a lanyard body and an adjusting device. The lanyard body is made of flexible rubber material, with fixed ends at both ends, which are fixedly connected to the two ends of the lanyard body via an embedded connection. The adjusting device is located in the middle region of the lanyard body and engages with the lanyard body via a sliding component to achieve length adjustment. The adjusting device includes an adjusting block and a locking mechanism. The adjusting block has a through-channel inside, and the inner wall of the through-channel has several protruding structures for engaging with grooves on the surface of the lanyard body, thereby restricting the sliding of the lanyard body. The locking mechanism is located on one side of the adjusting block and is used to lock the position of the lanyard body after adjustment.

[0007] The outer surface of the lanyard body is provided with evenly distributed grooves, which extend along the length of the lanyard body to form a continuous toothed structure. The inner wall of the through-channel of the adjusting block is provided with a protruding structure that matches the grooves. The protruding structure is semi-circular in shape and has an elastic pad at its top to increase the friction between it and the lanyard body. When the lanyard body passes through the adjusting block, the protruding structure engages with the grooves, thereby restricting the free sliding of the lanyard body.

[0008] As a preferred technical solution of this application, the adjusting block includes an outer shell and an inner core. The outer shell has a rectangular structure with an opening at its top communicating with a through channel for the insertion and exit of the hanging rope body. The inner core is located inside the outer shell and is fixedly connected to the outer shell by a threaded connection. The outer surface of the inner core has several protruding structures, the spacing of which is equal to the spacing of the grooves on the surface of the hanging rope body to ensure a tight fit between the two.

[0009] As a preferred technical solution of this application, the locking mechanism includes a pressure plate and a spring assembly. The pressure plate is located on one side of the adjusting block and is connected to the adjusting block by a hinge. A pressure block is provided at the bottom of the pressure plate. The shape of the pressure block matches the outer surface of the hanging rope body and is used to apply pressure to the hanging rope body in the locked state. The spring assembly is located on the back of the pressure plate and is fixedly connected to the adjusting block by bolts. When the pressure plate is in the open state, the hanging rope body can slide freely; when the pressure plate is in the closed state, the pressure block contacts the surface of the hanging rope body and the elastic force provided by the spring assembly fixes the hanging rope body in the current position.

[0010] As a preferred technical solution of this application, the fixed end includes a connecting ring and a fixing seat, wherein the connecting ring is connected to the fixing seat by a snap-fit ​​method. The fixing seat has an internal cavity, the shape of which matches the end of the hanging rope body to accommodate the end of the hanging rope body. The end of the hanging rope body is fixedly connected to the inner wall of the cavity of the fixing seat by a hot-melt process, thereby forming a firm connection.

[0011] As a preferred technical solution of this application, a reinforcing rib is provided in the middle region of the main body of the hanging rope. The reinforcing rib extends along the length of the main body of the hanging rope to improve the tensile strength of the main body of the hanging rope. The cross-sectional shape of the reinforcing rib is elliptical, and its thickness is less than the thickness of the main body of the hanging rope to avoid affecting the flexibility of the main body of the hanging rope.

[0012] As a preferred technical solution of this application, the top of the outer shell of the adjusting block is provided with anti-slip texture, the anti-slip texture being wavy in shape to increase friction during user operation. Mounting holes are provided on both sides of the outer shell for connecting to external devices.

[0013] As a preferred embodiment of this application, the spring assembly includes a spring and a guide rod. The spring is sleeved on the outside of the guide rod and fixedly connected to the guide rod by a nut. One end of the guide rod is fixedly connected to a pressure plate, and the other end is fixedly connected to the outer shell of the adjusting block. The compression of the spring is adjustable, allowing for adjustment of the locking force of the locking mechanism according to user needs.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The adjustable block and locking mechanism allow for precise adjustment of the lanyard length. The protruding structure inside the adjusting block engages with the grooves on the surface of the lanyard, restricting its free sliding and ensuring the adjusted length remains unchanged despite external forces. The locking mechanism, through the cooperation of a pressure plate and spring assembly, applies pressure to the lanyard after adjustment, further enhancing its stability. Furthermore, the lanyard is made of flexible rubber, offering excellent durability and comfort, making it suitable for various usage scenarios.

[0016] The reinforcing ribs enhance the tensile strength of the rope while maintaining its flexibility, making it less prone to breakage during frequent use. The fixed end is securely connected to the rope body via a heat-fusion process, ensuring a strong connection and preventing loosening due to prolonged use.

[0017] The anti-slip texture and mounting holes enhance the ease of operation of the adjustment block and expand the application range of the lanyard, enabling quick connection to external devices. The spring assembly design allows the locking force of the locking mechanism to be adjusted according to user needs, meeting the requirements of different scenarios.

[0018] In summary, this utility model, through reasonable structural design and material selection, solves the problems of insufficient adjustment, easy loosening or damage of existing hanging ropes, while improving the durability and comfort of the hanging ropes, and has high practical value and promotion significance.

[0025] This utility model provides an adjustable rubber lanyard, the specific implementation of which is described in detail with reference to the accompanying drawings. Figure 1 As shown, the lanyard includes a lanyard body 1, an adjusting device 2, and a fixed end 3. The lanyard body 1 is made of flexible rubber material, and its two ends are fixedly connected to the fixed end 3 via an embedded connection. The adjusting device 2 is located in the middle area of ​​the lanyard body 1 and cooperates with the lanyard body 1 through a sliding component to achieve the length adjustment function. The specific structure of each component and its interrelationships are described in detail below with reference to the accompanying drawings.

[0026] The outer surface of the lanyard body 1 is provided with evenly distributed grooves 8, which extend along the length of the lanyard body 1 and form a continuous tooth-like structure. For example... Figure 4 As shown, the interior of the rope body 1 also has reinforcing ribs 11, which are arranged along the length of the rope body 1. The reinforcing ribs 11 have an elliptical cross-section and a thickness less than the thickness of the rope body 1. The function of the reinforcing ribs 11 is to increase the tensile strength of the rope body 1 while maintaining its flexibility. Both ends of the rope body 1 are connected to fixed ends 3, which include connecting rings and fixing seats. The fixing seats have internal cavities whose shape matches the ends of the rope body 1. The ends of the rope body 1 are fixedly connected to the inner wall of the fixing seats through a heat-fusion process, thereby ensuring the strength of the connection. The connecting rings are connected to the fixing seats via a snap-fit ​​mechanism, facilitating the connection of the rope to other equipment or objects.

[0027] The adjusting device 2 includes an adjusting block 4 and a locking mechanism 5. For example... Figure 2 As shown, the adjusting block 4 has a through channel 6 inside, through which the hanging rope body 1 passes. The inner wall of the through channel 6 has several protruding structures 7, which are semi-circular in shape and have elastic pads at their tops. The protruding structures 7 match the grooves 8 on the surface of the hanging rope body 1. When the hanging rope body 1 passes through the adjusting block 4, the protruding structures 7 and the grooves 8 engage with each other, restricting the free sliding of the hanging rope body 1. The adjusting block 4 includes an outer shell and an inner core. The outer shell has a rectangular structure with an opening at its top communicating with the through channel 6 for the hanging rope body 1 to pass through and exit. The inner core is located inside the outer shell and is fixedly connected to the outer shell by a threaded connection. The outer surface of the inner core also has several protruding structures 7, the spacing of which is equal to the spacing of the grooves 8 on the surface of the hanging rope body 1, to ensure a tight fit.

[0028] The locking mechanism 5 is located on one side of the adjusting block 4, such as... Figure 3 As shown, the locking mechanism 5 includes a pressure plate 9 and a spring assembly 10. The pressure plate 9 is connected to the adjusting block 4 by a hinge, and a pressure block is provided at the bottom of the pressure plate 9. The shape of the pressure block matches the outer surface of the hanging rope body 1. The spring assembly 10 is located on the back of the pressure plate 9 and is fixedly connected to the adjusting block 4 by bolts. The spring assembly 10 includes a spring and a guide rod. The spring is sleeved on the outside of the guide rod and fixedly connected to the guide rod by a nut. One end of the guide rod is fixedly connected to the pressure plate 9, and the other end is fixedly connected to the outer shell of the adjusting block 4. The compression of the spring can be changed by adjusting the nut, thereby adjusting the locking force of the locking mechanism 5 according to the user's needs. When the pressure plate 9 is in the open state, the hanging rope body 1 can slide freely; when the pressure plate 9 is closed, the pressure block contacts the surface of the hanging rope body 1, and the elastic force provided by the spring assembly 10 fixes the hanging rope body 1 in the current position.

[0029] The top of the housing of the adjusting block 4 is provided with anti-slip texture 12, which is wavy in shape to increase friction during user operation. Mounting holes 13 are provided on both sides of the housing for connecting to external devices. By providing mounting holes 13, the lanyard can be quickly connected to external devices, expanding its application range.

[0030] In actual use, the user first passes the lanyard body 1 through the through-channel 6 of the adjusting block 4, so that the groove 8 on the surface of the lanyard body 1 engages with the protruding structure 7 on the inner wall of the through-channel 6. At this time, the length of the lanyard body 1 can be initially adjusted by manually pulling. After the lanyard length is adjusted to the appropriate position, the user closes the pressure plate 9 of the locking mechanism 5. The pressure block at the bottom of the pressure plate 9 contacts the surface of the lanyard body 1, and the elastic force provided by the spring assembly 10 fixes the lanyard body 1 in the current position. The compression of the spring assembly 10 can be adjusted according to the user's needs to meet the locking force requirements in different scenarios. When it is necessary to adjust the lanyard length again, the user only needs to open the pressure plate 9, and the lanyard body 1 will return to its free sliding state.

[0031] The reinforcing ribs 11 of the lanyard body 1 provide support when the lanyard is under tension, preventing it from breaking due to excessive stretching. The fixed end 3 is fixedly connected to the end of the lanyard body 1 via a heat-fusion process, ensuring a firm connection and preventing loosening due to prolonged use. The connecting ring of the fixed end 3 is connected to the fixing base via a snap-fit ​​mechanism, facilitating the connection of the lanyard to other equipment or objects. The anti-slip texture 12 on the top of the adjusting block 4's outer shell and the mounting holes 13 on both sides further enhance operational convenience and versatility in application scenarios.

[0032] In the above embodiments, the flexible rubber material of the lanyard body 1 has good durability and comfort, suitable for use in various scenarios. The adjustment device 2 achieves precise adjustment of the lanyard length through the cooperation of the adjustment block 4 and the locking mechanism 5, ensuring that the adjusted length will not change due to external forces. The groove 8 on the surface of the lanyard body 1 and the protruding structure 7 on the inner wall of the adjustment block 4 engage with each other, restricting the free sliding of the lanyard body 1 and further enhancing the stability of the lanyard. The design of the spring assembly 10 allows the locking force of the locking mechanism 5 to be adjusted according to user needs, meeting the usage requirements in different scenarios.

[0033] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principles of this utility model are further explained below in conjunction with specific application scenarios.

[0034] When using this adjustable rubber lanyard, the user first fixes both ends of the lanyard body 1 to the equipment or object to be connected. The fixing end 3 is heat-fused to the end of the lanyard body 1 through its internal cavity, ensuring a secure connection. The connecting ring is connected to the fixing base via a snap-fit ​​mechanism, facilitating quick disassembly and replacement of the lanyard body 1. This design makes the lanyard suitable for various scenarios, such as carrying outdoor equipment and hanging name tags.

[0035] Next, when the length of the lanyard needs to be adjusted, the user manually pulls the lanyard body 1, allowing it to pass through the through-channel 6 of the adjusting block 4. At this time, the groove 8 on the surface of the lanyard body 1 engages with the protruding structure 7 on the inner wall of the through-channel 6. Because the top of the protruding structure 7 has an elastic pad and its shape is semi-circular, the friction between the protruding structure 7 and the groove 8 effectively restricts the free sliding of the lanyard body 1 during its sliding process, thus achieving the initial length adjustment function. This toothed engagement design avoids the loosening problem caused by insufficient friction in traditional lanyards, while also improving the adjustment accuracy.

[0036] After the lanyard length is adjusted to the appropriate position, the user operates the locking mechanism 5 to lock the position of the lanyard body 1. Specifically, the user closes the pressure plate 9, and the pressure block at the bottom of the pressure plate 9 makes tight contact with the surface of the lanyard body 1. The spring assembly 10 provides elastic force through the cooperation of the guide rod and the nut, so that the pressure block applies stable pressure to the lanyard body 1. During this process, the compression of the spring can be changed by adjusting the nut, thereby flexibly adjusting the locking force according to actual needs. For example, when a stronger fixing effect is required, the user can increase the compression of the spring; while in scenarios where the length is frequently adjusted, the compression can be appropriately reduced to improve the ease of operation. This design ensures the adaptability and stability of the lanyard in different usage scenarios.

[0037] The presence of reinforcing ribs 11 further enhances the tensile strength of the main body 1 of the hanging rope. When the hanging rope is subjected to significant tension, the reinforcing ribs 11, distributed along the length of the main body 1, effectively disperse stress and prevent the hanging rope from breaking due to excessive stretching. In addition, the elliptical cross-section design of the reinforcing ribs 11 ensures sufficient support performance without significantly affecting the flexibility of the main body 1 of the hanging rope, maintaining a good user experience even when bent or twisted.

[0038] The anti-slip texture 12 on the top of the adjusting block 4 provides additional friction support during user operation. The wavy anti-slip texture 12 design not only enhances the feel but also reduces slippage during operation, especially in wet or oily environments. Meanwhile, the mounting holes 13 on both sides of the casing allow for quick connection of the lanyard to other external devices, expanding its application range. For example, users can secure the lanyard to backpacks, belts, or other load-bearing devices through the mounting holes 13, meeting diverse needs.

[0039] In summary, through the above steps and the synergistic effect between the components, this invention achieves precise adjustment of the lanyard length and a stable fixing effect. The flexible rubber material of the lanyard body 1 provides it with excellent durability and comfort, suitable for use in various complex environments. The interlocking design of the protrusion structure 7 and the groove 8 in the adjustment device 2, and the adjustable characteristics of the spring assembly 10 in the locking mechanism 5, together ensure that the length of the lanyard after adjustment will not change due to external forces. These features make this invention more reliable and practical than existing technologies.
