Detailed Implementation

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figs. 1-3 As shown in the figure, this embodiment proposes a fiber optic grating cable force sensor mounting structure, including a mounting clamp 1, a cable 2, and a cable force sensor body 3. The mounting clamp 1 includes a mounting base 4, a first mounting hole 5, and a second mounting hole 6. The mounting base 4 has a locking gap 7 in the middle. The upper end of the mounting base 4 has a first mounting hole 5 for mounting the cable force sensor body 3, and the lower end of the mounting base 4 has a second mounting hole 6 for mounting the cable 2. The mounting base 4 has symmetrical locking holes 8 located above the first mounting hole 5 and the second mounting hole 6. One end of the locking hole 8 also has a hexagonal limiting hole 9. A hexagonal bolt 10 passes through the locking hole 8. The cable 2 and the cable force sensor body 3 are fixed in the first mounting hole 5 and the second mounting hole 6 respectively by the hexagonal bolt 10 and the locking hole 8.

[0020] This device uses a first mounting hole 5 and a second mounting hole 6 on the mounting base 4 for mounting the cable force sensor and the cable 2, respectively. A locking gap 7 is provided in the middle of the mounting base 4. Above the first mounting hole 5 and the second mounting hole 6, there is a locking hole 8 and a hexagonal bolt 10. The tightening force generated by screwing in the nut of the hexagonal bolt 10 reduces the locking gap 7, thereby clamping and fixing the cable force sensor and the cable 2. The hexagonal limiting hole 9 limits one end of the hexagonal bolt 10, facilitating the installation of the nut of the hexagonal bolt 10. This makes the installation and disassembly of the cable force sensor and the cable 2 quite convenient.

[0021] The cable force sensor body 3 is also provided with threaded heads 11 at both ends, and nuts 12 are threadedly installed on the threaded heads 11.

[0022] By setting threaded heads 11 at both ends of the cable force sensor body 3 and cooperating with nuts 12 to tighten and fix both ends of the cable force sensor, the installation of the cable force sensor body 3 is further fixed, ensuring that the cable force sensor body 3 will not fall off due to other factors during long-term use.

[0023] The inner wall of the second mounting hole 6 is symmetrically provided with grooves 13, and an arc-shaped clamping plate 14 is provided in the grooves 13. Adjusting screws 15 are symmetrically provided on both outer walls of the mounting base 4. One end of the adjusting screw 15 passes through the mounting base 4 and is rotatably connected to the arc-shaped clamping plate 14.

[0024] This device uses the rotating adjusting screw 15 to move the arc-shaped clamping plate 14 to clamp the cable 2, further increasing the clamping force between the second mounting hole 6 and the cable 2, and further increasing the fixing effect of the cable 2 after installation.

[0025] After the two sets of arc-shaped clamps 14 are embedded in the grooves 13, the distance between the inner walls of the two sets is equal to the inner diameter of the second mounting hole 6.

[0026] The purpose of storing the arc-shaped clamp 14 by setting the groove 13 is to ensure that the setting of the arc-shaped clamp 14 will not affect the installation of the cable 2.

[0027] The inner side of the arc-shaped clamp 14 is provided with anti-slip texture, which is strip-shaped. The anti-slip texture further increases the friction between the arc-shaped clamp 14 and the cable.

[0028] In actual installation and use, the fiber optic grating cable force sensor mounting structure is used by rotating the nut of the hexagonal bolt 10 to open the locking gap 7, then installing the cable force sensor body 3 in the first mounting hole 5, and the cable 2 in the second mounting hole 6. The nut of the hexagonal bolt 10 is then tightened to clamp and fix it. Then, by rotating the adjusting screw 15, the arc-shaped clamping plate 14 is pushed to further clamp the cable 2, ensuring the cable 2 is fixed. At the same time, the cable force sensor body 3 is fixed by tightening the threaded head 11 and the nut 12.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
