Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing, and particularly relates to a flexible wire clamp device. Background Art

[0002] Cable clamps play a crucial role in the power and communication industries. After cables are laid and installed, they are used to ensure that the cables maintain their correct positions during operation and prevent the cables from moving due to external forces or their own weights. However, existing cable clamp devices still face some technical deficiencies.

[0003] The prior art CN201911159161.4 discloses a triangular cable clamp, which is fixed to a bracket by bolts and includes a cover plate, a base, and a Y-shaped isolation component. In this design, the base is provided with two connected grooves and is connected by a boss. The cover plate is fixed directly above the base to form a triangular structure. The Y-shaped isolation component is inserted into the boss, which can reduce the impact load during cable short-circuit faults, reduce the damage probability of the clamp, and improve the vibration damping effect, thereby extending the service life of the clamp. In addition, the electromagnetic vibration energy of the cable is reduced through flexible connection. However, designs such as this still have the following defects and deficiencies:

[0004] 1. Limited adaptability: Existing cable clamps mainly achieve cable fixation through fixed groove structures, lacking sufficient flexibility when dealing with cables of different specifications. Since the groove sizes are fixed, when using cables of different sizes, the adaptability of the clamps is limited. Different-sized clamps may need to be designed for different cable specifications, and they cannot be flexibly adjusted to accommodate multiple cable specifications, resulting in poor adaptability.

[0005] 2. Inconvenient installation and adjustment: Existing clamps rely on the installation method of bolts and fixed grooves. Although they provide a certain degree of stability, the installation process is relatively cumbersome, and it is not flexible enough when the cable position needs to be adjusted. This structure results in low installation efficiency and increases the complexity of construction and maintenance.

[0006] 3. Complex structure and easy to be damaged: Although the Y-shaped isolation component inside the existing triangular cable clamp can reduce certain vibrations and impacts, the overall structure is relatively complex, increasing the manufacturing and maintenance costs, and may be damaged due to uneven stress under extreme conditions.

[0007] 4. Uneven stress distribution: Due to the fixed structure of the clamp, stress concentration is likely to occur at the contact part between the cable and the clamp. Prolonged use may cause cable wear or clamp damage, affecting the overall service life of the equipment. Summary of the Utility Model

[0008] The problem to be solved by the utility model is that the existing cable clamps have limited adaptability, inconvenient installation and adjustment, complex structure, easy damage and uneven stress distribution.

[0009] In order to solve the above problems, the utility model provides a flexible wire clamp device, including a U-shaped clamping part, a positioning connection part is fixedly provided at the lower end of the U-shaped clamping part, and a flexible cable clamping part is fixedly provided at the bottom of the positioning connection part, and the flexible cable clamping part includes a limiting clamping groove opened at the front end, a clamping seat is provided at the inner rear end of the limiting clamping groove, an elastic clamping block is provided in the clamping seat, a U-shaped reserved groove is provided between the elastic clamping block and the clamping seat, and an arc-shaped protrusion is provided at the end of the elastic clamping block away from the limiting clamping groove. When the cable contacts the elastic clamping block, the elastic clamping block elastically bends to clamp cables of different specifications.

[0010] Preferably, the arc-shaped protrusion and the end of the clamping seat away from the limiting clamping groove are both provided with an inward protrusion.

[0011] Preferably, the U-shaped clamping portion includes a U-shaped clamping seat, and a plurality of cable clamping convex strips are distributed from top to bottom on the inner edge of the U-shaped clamping seat. A front-to-back through-the-way slot is provided at the center of the U-shaped clamping seat. The slot facilitates the installation and adjustment of the cable, making the operation of the cable during the installation process more convenient and improving the installation efficiency.

[0012] Preferably, the outer edge of the U-shaped clamping seat is provided with an outwardly protruding arched reinforcement rib.

[0013] Preferably, the positioning connection portion comprises a positioning connection seat, and a positioning clamping groove ring penetrating front to back is provided at the center of the positioning connection seat.

[0014] Preferably, both left and right ends of the positioning clamp groove ring are provided with docking clamp rings, and the docking clamp rings are provided with radius clamping protrusions protruding outwards.

[0015] Preferably, the radius clamping protrusions in the docking clamp rings at the left and right ends are arranged in a mirror image.

[0016] Compared with the prior art, the utility model has the following beneficial technical effects:

[0017] Strong adaptability: The utility model can effectively adapt to small and medium-sized cables of different specifications by arranging elastic clamping blocks and limiting clamping grooves in the flexible cable clamping part; the elastic clamping block allows it to bend elastically when clamping small and medium-sized cables of different sizes, thereby ensuring that the cables are firmly fixed without damage; the U-shaped clamping part enables the device to clamp large-sized cables, with a wider adaptability, realizing universal clamping of cables of multiple specifications, and solving the problem of poor adaptability of existing wire clamps when facing different cable specifications.

[0018] Enhanced fixing effect: An arc-shaped protrusion is provided at one end of the elastic clamping block of the utility model away from the limiting clamping groove. The arc-shaped protrusion can also press against the cable from the rear end of the elastic clamping block when the elastic clamping block is bent to clamp the cable. It can provide stronger friction and fixing force when clamping the cable, preventing the cable from moving due to external force or its own weight, thereby improving the fixing effect of the cable.

[0019] Stable structure: The outer edge of the U-shaped clamping seat is provided with arched reinforcement ribs, which not only increases the structural strength of the clamping part, but also improves the durability and impact resistance of the entire wire clamp device. It can maintain stability in harsh environments and also avoids damage caused by uneven force during use.

[0020] 4. Reliable connection: The utility model ensures a stable connection between the flexible wire clamp device and the supporting structure docked at the rear end through the structural setting of the positioning clamp groove ring and the docking clamp ring of the positioning connection part. The radius clamping protrusion enhances the reliability of the connection and prevents the wire clamp device from loosening or falling off during use. It can ensure that the wire clamp is accurately positioned during installation and reduce the hidden dangers caused by inaccurate positioning.

[0021] 5. Reduce stress concentration: The radius clamping protrusions in the docking clamp ring of the positioning connection part of the utility model are arranged in a mirror image, which helps to maintain the symmetry of the device during installation, ensures consistent mechanical properties in all directions, and ensures that the stress is evenly distributed when the flexible wire clamp device is connected to the supporting structure at the rear end. The arc-shaped protrusions and the inward protrusions on the clamping seat can effectively reduce the stress concentration between the cable and the flexible wire clamp device, protect the cable and increase the service life of the flexible wire clamp device.

[0036] In order to facilitate understanding of the above technical solution of the present invention, the above technical solution of the present invention is described in detail below through specific usage methods.

[0037] The specific working process is:

[0038] Put the large-sized cable into the U-shaped clamping seat 101 of the U-shaped clamping part 1, and the cable clamping convex strip 102 on the inner edge of the U-shaped clamping seat 101 clamps and fixes the position of the large-sized cable. Then adjust the cable position and make fine adjustments to the cable to ensure the accuracy of the cable position and reduce the difficulty of installation. Then pass the small and medium-sized cables through the clamping seat 302 in the limit clamping groove 301 of the flexible clamping cable part 3. When the cable contacts the elastic clamping block 303 on the clamping seat 302, the elastic clamping block 303 will bend elastically when contacting the cable, so that the clamping is suitable for small and medium-sized cables of different specifications. The arc-shaped protrusion 305 can also press against the cable from the rear end of the elastic clamping block 303 when the elastic clamping block 303 is bent to clamp the cable.
