[0033] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The following combination Figure 1-Figure 5 Description The cable fixing device in a bridge of the present invention is generally designed to be used inside a bridge to ensure the stability and safety of the cable 30.

[0035] In some embodiments, as Figures 1 to 4 As shown, the cable fixing device in a cable bridge includes a positioning mechanism 10 and an elastic adjustment mechanism 20. The positioning mechanism 10 is formed with a concave groove 100 for installation on an external structure; the elastic adjustment mechanism 20 is adapted to be detachably installed in the concave groove 100. When the elastic adjustment mechanism 20 is installed in the concave groove 100, the sidewall of the concave groove 100 squeezes the elastic adjustment mechanism 20, so that the elastic adjustment mechanism 20 forms an installation space for clamping the cable 30.

[0036] In this embodiment, the cable fixing device in a cable bridge primarily consists of a positioning mechanism 10 and an elastic adjustment mechanism 20. The positioning mechanism 10 is the foundation of the device, forming a concave groove 100. Through the design of the concave groove 100, the positioning mechanism 10 provides stable support for the elastic adjustment mechanism 20, ensuring that it can be securely fixed in its intended position.

[0037] The elastic adjustment mechanism 20 is designed to be removably mounted within the concave groove 100. This design provides significant convenience for the user, allowing the elastic adjustment mechanism 20 to be flexibly installed or removed as needed. More importantly, when the elastic adjustment mechanism 20 is mounted within the concave groove 100, the sidewalls of the concave groove 100 exert pressure on the elastic adjustment mechanism 20.

[0038] This squeezing action causes the elastic adjustment mechanism 20 to deform, thereby forming a mounting space specifically for clamping the cable 30. The size of this mounting space can be modified by adjusting the position or shape of the elastic adjustment mechanism 20 to accommodate cables 30 of different sizes and types. This design not only ensures a secure clamping of the cable 30, but also enables the device to adapt to various cable 30 installation requirements.

[0039] The cable fixing device in the bridge provided by the embodiment of the present invention, through the coordinated design of the concave groove 100 and the elastic adjustment mechanism 20, enables the elastic adjustment mechanism 20 to form an installation space that adapts to cables 30 of different diameters when squeezed by the side wall of the concave groove 100, thereby effectively enhancing the fixing effect of the cable 30 and preventing the cable 30 from shaking or falling off in the bridge. Since the elastic adjustment mechanism 20 is detachably arranged in the concave groove 100, the user can easily complete the fixing of the cable 30 during installation without complicated operating steps or professional tools, greatly improving the convenience of the installation operation. This design allows the user to easily disassemble the elastic adjustment mechanism 20 and maintain or replace the cable 30 without damaging the bridge or the cable 30. This reduces the difficulty and cost of subsequent maintenance and improves the overall convenience of use. Since the elastic adjustment mechanism 20 can be adaptively adjusted according to the diameter of the cable 30, the fixing device can be widely used to fix cables 30 of different specifications and types, and has strong versatility and adaptability.

[0040] It should be noted that if Figure 2 As shown, in general, there are multiple cable fixing devices in the bridge, and each cable fixing device in the bridge is used to fix a corresponding cable 30. In order to ensure the fixing effect, as shown in FIG. Figure 4 As shown, multiple cable fixing devices in the bridge can also be provided for each cable 30. This approach provides additional stability and support, especially when the cable 30 is long, heavy or the bridge environment is complex, and can better ensure the safety and reliability of the cable 30.

[0041] In some embodiments, as Figures 1 to 4 As shown, the positioning mechanism 10 is a positioning base, and the concave groove 100 includes a port portion 101, a clamping portion 102 and an end bottom portion 103; the edges of the port portion 101, the clamping portion 102 and the end bottom portion 103 are connected in sequence, and the diameter of the port portion 101 gradually decreases toward the bottom of the concave groove 100, and the diameter of the clamping portion 102 gradually increases toward the bottom of the concave groove 100.

[0042] Specifically, the concave groove 100 includes three main areas: a port portion 101, a clamping portion 102, and a bottom portion 103. The edges of the port portion 101, the clamping portion 102, and the bottom portion 103 are smoothly connected in sequence to form a continuous groove structure. The design feature of the port portion 101 is that its diameter gradually decreases toward the bottom of the concave groove 100. This design facilitates the smooth insertion of the cable 30 and guides the cable 30 toward the clamping portion 102. The clamping portion 102 is the area in the concave groove 100 used to actually clamp the cable 30. Unlike the port portion 101, the diameter of the clamping portion 102 gradually increases toward the bottom of the concave groove 100. This structure enables the elastic adjustment mechanism 20 to gradually increase the clamping force on the cable 30 when it enters the clamping portion 102, ensuring stable fixation of the cable 30. The bottom portion 103 is located at the deepest part of the concave groove 100, and its structure helps to enhance the stability and load-bearing capacity of the entire positioning base. At the same time, the existence of the end bottom portion 103 also provides a stable supporting surface for the elastic adjustment mechanism 20 .

[0043] The end bottom portion 103 is U-shaped to cooperate with the clamping portion 102 to squeeze the elastic adjustment mechanism 20. The U-shaped configuration of the end bottom portion 103 actually creates a space that can accommodate and support the elastic adjustment mechanism 20. When the elastic adjustment mechanism 20 is placed in the concave groove 100, the U-shaped structure of the end bottom portion 103 can provide stable support for it. At the same time, because the end bottom portion 103 is tightly matched with the clamping portion 102, when the cable 30 is placed in the elastic adjustment mechanism 20, the clamping portion 102 will apply pressure to the elastic adjustment mechanism 20, and the U-shaped structure of the end bottom portion 103 can effectively disperse this pressure and feedback it to the elastic adjustment mechanism 20, thereby ensuring that the cable 30 is evenly and firmly clamped.

[0044] In addition, the U-shaped end bottom 103 also helps to improve the flexibility and adaptability of the entire device. Due to its open design, it can accommodate elastic adjustment mechanisms 20 of different shapes and sizes, making the device applicable to a wider range of scenarios and needs.

[0045] In some embodiments, as Figures 1 to 4 As shown, a mounting hole is provided in the concave groove 100 of the positioning mechanism 10; the cable fixing device in the bridge frame also includes a first fixing member 40, which is passed through the mounting hole and the external structure to connect the positioning mechanism 10 and the external structure.

[0046] In this embodiment, a mounting hole is specifically provided within the concave groove 100 of the positioning mechanism 10. This design allows the positioning mechanism 10 to be more securely connected to the external structure. To further strengthen this connection, the cable fixture within the bridge also includes a first fixing member 40. The first fixing member 40 is inserted through the mounting hole and the external structure, effectively connecting the positioning mechanism 10 to the external structure. This connection method not only ensures the stability of the positioning mechanism 10, but also ensures that the entire cable 30 fixture can be securely fixed in the predetermined position and will not move or loosen due to external factors (such as vibration, wind, etc.).

[0047] Generally, the first fixing member 40 is usually a bolt or a screw. Bolts and screws are common fasteners that are easy to install and have a stable structure, and are very suitable for connecting the positioning mechanism 10 and the external structure.

[0048] Using bolts or screws as the first fixing member 40 can ensure a firm and reliable connection between the positioning mechanism 10 and the external structure. During the installation process, the bolts or screws pass through the mounting holes and are screwed into the corresponding holes of the external structure to achieve a tight connection between the two.

[0049] In some examples, such as Figures 1 to 3 As shown, the elastic adjustment mechanism 20 includes a sleeve portion 210 and two flared portions 220. The two ends of the sleeve portion 210 are respectively connected to the flared portions 220. When the elastic adjustment mechanism 20 is installed in the concave groove 100, the sidewall of the concave groove 100 squeezes the sleeve portion 210 and the two flared portions 220 to form an installation space.

[0050] When the elastic adjustment mechanism 20 is placed in the concave groove 100, the sidewalls of the concave groove 100 exert an extrusion effect on the clamping portion 210 and the two flared portions 220. This extrusion not only makes the elastic adjustment mechanism 20 more firmly fixed in the concave groove 100, but more importantly, it causes the clamping portion 210 and the flared portions 220 to deform, thereby forming a space for installing the cable 30.

[0051] Specifically, the ferrule portion 210 contracts inward when squeezed, while the two flared portions 220 expand inward, thereby forming a mounting space that can tightly clamp the cable 30. This design not only ensures a secure installation of the cable 30, but also effectively prevents the cable 30 from sliding or falling off during installation.

[0052] In general, the design of the elastic adjustment mechanism 20 cleverly utilizes the squeezing effect of the concave groove 100 to achieve efficient and stable installation of the cable 30. This design not only improves the reliability of the cable 30 fixation, but also greatly simplifies the installation operation, making the entire installation process more convenient and efficient.

[0053] In this embodiment, the ferrule portion 210 is arranged in a three-quarter circular shape. This shape not only ensures the stability of the structure, but also provides sufficient elasticity, so that the ferrule portion 210 can undergo appropriate deformation when squeezed by the side wall of the concave groove 100, thereby better adapting to and fixing the cable 30. The two flared portions 220 and the ferrule portion 210 are designed to be integrally formed, which not only enhances the overall structural strength, but also ensures that there is no significant stress concentration at the connection between the flared portion 220 and the ferrule portion 210, thereby improving the service life. At the same time, the one-piece design also makes the elastic adjustment mechanism 20 easier to manufacture, which is conducive to improving production efficiency. When the elastic adjustment mechanism 20 is placed in the concave groove 100, due to the three-quarter circular design of the ferrule portion 210 and the one-piece structure of the flared portion 220, the entire mechanism can be evenly stressed when squeezed, and a stable cable 30 installation space is formed. This design ensures that the cable 30 can be firmly fixed in the bridge and will not move or fall off due to external factors.

[0054] In some embodiments, as Figure 5 As shown, the elastic adjustment mechanism 20 also includes: a second fixing member 230; fixing holes are provided on the two flared parts 220; when the elastic adjustment mechanism 20 is arranged in the concave groove 100, under the extrusion of the side wall of the concave groove 100, the fixing holes of the two flared parts 220 are arranged relative to each other, and the second fixing member 230 is passed through the two fixing holes to connect the two flared parts 220, so that the sleeve part 210 and the two flared parts 220 form an annular installation space.

[0055] In this embodiment, the second fixing member 230 is used to enhance the stability of the structure and adjust the shape of the installation space. When the elastic adjustment mechanism 20 is placed in the concave groove 100, the side walls of the concave groove 100 squeeze the sleeve portion 210 and the flared portion 220. Under this squeezing effect, the fixing holes of the two flared portions 220 are arranged relative to each other, so that the second fixing member 230 can be smoothly inserted into the two fixing holes. The insertion of the second fixing member 230 connects the two flared portions 220, further enhancing the integrity and stability of the elastic adjustment mechanism 20. Importantly, through the connection of the second fixing member 230, the sleeve portion 210 and the two flared portions 220 together form an annular installation space. This annular installation space can not only clamp the cable 30 more evenly, preventing the cable 30 from sliding or twisting during installation, but also better adapt to cables 30 of different diameters, providing greater flexibility and adaptability.

[0056] Based on the above embodiments, in some embodiments, the elastic adjustment mechanism 20 is a single-layer or double-layer elastic structure.

[0057] The single-layer elastic structure is composed of a single layer of elastic material. It has good elasticity and recovery properties, and can quickly return to its original shape after being subjected to external forces. This structure is generally used in applications where elasticity requirements are not particularly high, or when the cable 30 has a small diameter and the clamping force required is moderate.

[0058] The double-layer elastic structure consists of two layers of elastic material, which may have a gap or connecting layer in between. This double-layer structure provides greater elasticity and clamping force, making it suitable for applications where the cable 30 is larger in diameter or where a stronger clamping force is required. It also increases the stability and durability of the adjustment mechanism.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
