Description

Technical Field

[0001] This utility model relates to the technical field of cable fixing mechanisms, and more specifically, to a cable fixing mechanism for earthquake detection. Background Technology

[0002] Cable fixing mechanisms for seismic detection are a crucial component of seismic monitoring systems. Their primary function is to securely install and fix the cables of seismic detection instruments, ensuring good connection even in complex field environments and guaranteeing stable transmission of seismic monitoring data. Effective cable fixing prevents loosening and damage caused by external forces, vibrations, and other factors, thereby improving the reliability and accuracy of seismic detection work.

[0003] However, existing cable fixing mechanisms for seismic detection have many drawbacks. On the one hand, fixing cables usually requires the use of specially sized fixing brackets, which are difficult to adapt to cables of different specifications and have poor versatility. Furthermore, fixing requires the use of tools to tighten adjusting bolts to clamp and fix the cable, which is cumbersome and extremely inconvenient for installation and maintenance in complex field environments. On the other hand, traditional cable fixing structures are often directly fixed in a designated position, lacking effective seismic buffer design and resulting in poor seismic resistance. In seismic detection, the detection locations are mostly in earthquake-prone areas. During an earthquake, strong vibrations can easily damage the cables of the detection instruments, seriously affecting the normal conduct of subsequent detection work and the stable transmission of signals, thereby reducing the accuracy and reliability of seismic monitoring data.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a cable fixing mechanism for earthquake detection, which has the following advantages:

[0015] 1. This seismic detection cable fixing mechanism, through the installation of lugs, ball head seats, ball heads, rubber blocks, and springs, enables the seismic detection cable fixing mechanism to improve the seismic performance of the cable. Through the coordinated arrangement of ball head seats, ball heads, shock absorbers, rubber blocks, and springs, one end of the shock absorber can swing in multiple directions inside the lugs during use. When swinging, it squeezes the rubber block in the corresponding direction, thereby absorbing the kinetic energy during the swing through the cooperation of the rubber block and the spring. The spring also helps the shock absorber to return to its original position, thus achieving the purpose of improving the seismic performance of the cable.

[0016] 2. This seismic detection cable fixing mechanism, through the arrangement of a sliding rod, an upper clamping frame, a lower clamping frame, a clamping spring, a limiting lever, and a hand-operated block, facilitates the clamping and fixing of cables. The coordinated arrangement of the sliding rod, upper clamping frame, lower clamping frame, and clamping spring allows the lower clamping frame to be pushed against the upper clamping frame during use to clamp the cable in between. The coordinated arrangement of the clamping spring, limiting lever, support rod, and hand-operated block effectively prevents the clamping effect of the lower and upper clamping frames from loosening during actual use. Furthermore, the support rod and hand-operated block allow the lower clamping frame to slide downwards quickly, facilitating cable placement, thus achieving the purpose of quickly clamping and fixing the cable.

[0028] Please see Figures 1-4 A cable fixing mechanism for earthquake detection includes a mounting lug 1, characterized in that: a shock-absorbing shell 2 is fixedly connected to the upper surface of the mounting lug 1, a ball head seat 3 is fixedly connected to the inner lower wall of the shock-absorbing shell 2, a ball head 4 is movably connected to the inner side wall of the ball head seat 3, a shock-absorbing rod 5 is fixedly connected to the upper surface of the ball head 4, a connecting ball 6 is fixedly connected to the middle of the outer surface of the shock-absorbing rod 5, the outer surface of the connecting ball 6 is movably connected to the inner side wall of the rubber block 7, a spring 8 is spirally arranged, the inner side wall of the shock-absorbing shell 2 is engaged with the rubber block 7, and the inner side wall of the rubber block 7 is provided with the spring 8.

[0029] Specifically, in the initial state, the limiting lever 16 engages with the limiting slot 18 on the sliding rod 10, restricting the lower clamping frame 13 from moving downwards. When it is necessary to adjust the clamping position or release the cable, the hand gripping block 22 is slid downwards. The protrusion 23 on the inner side wall of the hand gripping block 22 presses against the upper surface of the support rod 17. The support rod 17 drives the limiting lever 16 to rotate around its connection point with the lower clamping frame 13, causing the limiting lever 16 to disengage from the limiting slot 18. At this time, the lower clamping frame 13 loses its limiting position and can slide downwards on the sliding rod 10, facilitating the adjustment of the cable position or the placement of a new cable. After the cable placement or adjustment is completed, the hand gripping block is released. Block 22, under the action of spring 19, the limiting lever 16 rotates back and re-engages into the appropriate limiting slot 18, preventing the lower clamping frame 13 from moving downward. Throughout the process, the clamping spring 15 always provides an upward elastic force, pushing the lower clamping frame 13 tightly towards the cable, cooperating with the upper clamping frame 12 to clamp the cable. Through this structural design, not only can the position of the lower clamping frame 13 be quickly adjusted, but also after the cable is placed, the limiting lever 16 and the limiting slot 18 can effectively prevent the lower clamping frame 13 from loosening and sliding down, ensuring stable clamping of the cable and achieving the purpose of facilitating quick clamping and fixing of the cable.

[0030] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7 A base plate 9 is fixedly connected to the upper end of the shock absorber 5. A sliding rod 10 is fixedly connected to the upper surface of the base plate 9. An upper clamping frame 12 is fixedly connected to the upper end of the sliding rod 10 by bolts 11. A lower clamping frame 13 is slidably connected to the outer surface of the sliding rod 10. Rubber pads 14 are provided on the inner side wall of the upper clamping frame 12. Two rubber pads 14 are provided and are respectively provided on the inner side wall of the upper clamping frame 12 and the inner side wall of the lower clamping frame 13. A groove adapted to the right end of the lower clamping frame 13 is opened at the right end of the upper clamping frame 12. A clamping spring 15 is provided on the upper surface of the base plate 9 outside the sliding rod 10. The upper end of the clamping spring 15 abuts against the lower surface of the lower clamping frame 13. The wall is rotatably connected to a limiting rod 16. A support rod 17 is fixedly connected to the outer surface of the limiting rod 16. A spring 19 is fixedly connected to the lower surface of the support rod 17. One end of the spring 19 abuts against the inner side wall of the lower clamping frame 13. A limiting groove 18 is opened on the outer surface of the sliding rod 10. Several limiting grooves 18 are provided and are evenly distributed in a rectangular array. One end of the limiting rod 16 is engaged with the inner side wall of the limiting groove 18. A hand-grip block 22 is slidably connected to the outer surface of the lower clamping frame 13 through a sliding groove 20 and a slider 21. A protrusion 23 is provided on the inner side wall of the hand-grip block 22. The lower surface of the protrusion 23 abuts against the upper surface of the support rod 17. An anti-slip texture 24 is provided on the outer surface of the hand-grip block 22.

[0031] Specifically, in actual earthquake detection scenarios, once a vibration occurs, the damping rod 5 connected to the cable will swing accordingly. One end of the damping rod 5 is movably connected to the ball head seat 3 via the ball head 4. The ball head seat 3 is fixed to the inner bottom of the damping shell 2. This connection method allows the damping rod 5 to swing flexibly in multiple directions within the ball head seat 3. When the damping rod 5 swings, it will compress the rubber block 7. The rubber block 7 has good elasticity and undergoes elastic deformation when compressed, absorbing part of the kinetic energy generated by the vibration. At the same time, the helical spring set on the inner wall of the rubber block 7... The spring plate 8 also deforms along with the rubber block 7. When deformed, it rubs against the rubber block 7, further absorbing vibration energy. Moreover, the elastic restoring force of the spring plate 8 can help the shock absorber rod 5 return to its initial position when the vibration weakens. Through the synergistic effect of the ball head seat 3, ball head 4, shock absorber rod 5, rubber block 7 and spring plate 8, the vibration of the cable can be effectively buffered during an earthquake, greatly reducing the degree of damage to the cable, thereby improving the seismic performance of the cable and ensuring the normal operation of the cable and the stable transmission of signals during earthquake detection.
