AI Technical Summary
Existing optical cable clamps are inconvenient to use because they are not easy to adjust the clamping of the optical cable, cannot efficiently adjust the clamping of the optical cable body, and are not convenient for clamping the cable in the vertical or horizontal direction. When the turntable position is fixed, it is not easy to fix it after rotation, which affects the stability of the optical cable and the working efficiency.
The system employs a combination structure of ball screw pair, screw nut pair, and limit rod, along with a handwheel and spring design, to achieve rapid clamping and fixation of optical cables and multi-directional cable clamping. The height of the cable rack is adjusted via the handwheel, and the sliding connection between the U-shaped limit plate and the clamping block achieves the limiting of the clamping slot. The movement of the clamping block provides further limitation, enabling rapid clamping and fixation and multi-directional cable clamping, thus improving the fixation of the cable. The height of the cable rack is adjusted via the handwheel, and the sliding connection between the U-shaped limit plate and the clamping block enables rapid clamping and fixation of optical cables and multi-directional cable clamping.
The stability and working efficiency of the optical cable have been improved. The height of the cable tray can be adjusted by handwheel, which enables the rapid clamping and fixing of the optical cable and multi-directional cable clamping, thus enhancing the practicality of the device.

Abstract
Description
Technical Field
[0001] This application relates to the field of cable clamps, and more specifically, to a cable clamp for optical cable laying. Background Technology
[0002] Fiber optic cable installation involves installing fiber optic cables on an overhead line structure to transmit optical signals. It is usually done in conjunction with cable clamps and tensioners. Cable clamps are used to secure the fiber optic cable to ensure its position and stability.
[0003] Existing fiber optic cable clamps have limitations in practical use. Due to the different diameters of different fiber optic cables, they bear different pressures. It is inconvenient to adjust the tightness of the fiber optic cable body during fixing, and it is not convenient to clamp the cable in the vertical or horizontal direction. Furthermore, when vertically stringing the cable, it is inconvenient to adjust the pulling length and stringing height, which has a certain impact on actual use.
[0004] Chinese patent application CN202420628259.X discloses an optical cable stringing clamp, relating to the field of optical cable stringing technology. It includes a fixed plate, a rotating mechanism mounted on one side of the fixed plate, and an adjusting mechanism mounted on the front of the fixed plate. The rotating mechanism includes a turntable movably mounted on one side of the fixed plate. A rotating shaft is mounted inside the turntable and penetrates the interior of the fixed plate. A card holder is fixedly mounted on the outer side of the turntable near its bottom. A wire groove is formed on the top of the card holder, and positioning holes are formed near the four corners of the bottom of the card holder. Two guide rails are fixedly mounted on the outer side of the turntable. A pressure plate is movably mounted around the two guide rails and on the outer side of the turntable. Fastening bolts are movably mounted near the four corners of the top of the pressure plate. This device facilitates adjustment of the optical cable clamping pressure, enabling vertical or horizontal clamping of the optical cable, and also facilitates adjustment of the pulling rod's traction length, thus allowing for convenient adjustment of the stringing height.
[0005] The above solution has the following shortcomings: When in use, four fastening bolts need to be tightened in sequence so that the pressure plate can press and fix the optical cable. The whole process is time-consuming and laborious, which reduces work efficiency. At the same time, after the turntable rotates in the fixed plate through the rotating shaft, it is not easy to fix the position of the turntable, which affects the stability of the optical cable and reduces the practicality of the device.

By pushing the U-shaped limiting plate 160 to slide in the second clamping seat 150, the clamping block 170 slides out of the placement groove and engages with the clamping groove 180, which facilitates quick and efficient clamping and fixing of the optical cable, improving work efficiency. By rotating the handwheel, the ball screw pair 121 is rotated, which causes the screw nut pair 122 to move, which facilitates adjustment of the stringing height. By pulling the slide rod 220, the first slider 230 is moved, and the spring 240 is squeezed, which causes the fixing plate 250 to disengage from the fixing groove 1301. The rotating cylinder 130 is rotated to a suitable position, and the spring 240 resets, causing the fixing plate 250 to engage with the new fixing groove 1301, which facilitates clamping the cable in different directions, making it easy to fix and improving the stability of the optical cable.
