With reference to fig. 1 to 8 of the drawings accompanying the present specification, an optical fiber net 100 according to a preferred embodiment of the present invention will be disclosed and described in the following description, wherein the optical fiber net 100 comprises a plurality of end-to-end parallel warp yarn segments 10, a plurality of end-to-end parallel weft yarn segments 20, and a plurality of locking units 30, the warp yarn segments 10 and the weft yarn segments 20 are woven by a complete optical fiber cable, the weft yarn segments 20 are located above the warp yarn segments 10 from a top view when the optical fiber net 100 is laid flat, and the extending directions of the weft yarn segments 20 and the warp yarn segments 10 are perpendicular to each other, wherein the locking units 30 are configured to prevent the warp yarn segments 10 and the weft yarn segments 20 from sliding relative to each other at crossing positions of the warp yarn segments 10 and the weft yarn segments 20 to ensure reliability of the optical fiber net 100, and to lock the warp yarn segments 10 and the weft yarn segments 20 from rubbing against each other when the optical fiber net 100 is in use, while the locking units 30 physically isolate the warp yarn segments 10 and the weft yarn segments 20 from each other in a thickness direction of the optical fiber net 100 to prevent rubbing against each other.
Specifically, turning now to fig. 2 to 8, the locking unit 30 includes a first locking cover 31, a second locking cover 32 and a spacer 33, the spacer 33 has a first locking side 331 and a second locking side 332 corresponding to the first locking side 331, wherein the spacer 33 is disposed between the warp thread segment 10 and the weft thread segment 20 at an intersection position of the warp thread segment 10 and the weft thread segment 20 to physically separate the warp thread segment 10 and the weft thread segment 20 by the spacer 33 from direct contact of the warp thread segment 10 and the weft thread segment 20, wherein the first locking cover 31 is covered on the first locking side 331 of the spacer 33 to lock the warp thread segment 10 by the first locking cover 31 and the spacer 33, wherein the second locking cover 32 is covered on the second locking side 332 of the spacer 33 to lock the weft thread segment 20 by the second locking cover 32 and the spacer 33, such that the warp thread segment 30 and the weft thread segment 20 are physically locked and the weft thread segment 20 is locked.
Further, the isolation portion 33 has a first positioning groove 333, the first positioning groove 333 is disposed on the first locking side 331, and the first locking cover 31 has a first receiving groove 311, wherein when the first locking cover 31 is disposed on the first locking side 331 of the isolation portion 33, the position of the first receiving groove 311 of the first locking cover 31 corresponds to the position of the first positioning groove 333 of the isolation portion 33, so as to form a first threading channel 34 of the locking unit 30 for receiving the string 10. The diameter of the first threading channel 34 of the locking unit 30 is equal to or slightly smaller than the diameter of the warp yarn section 10, so that after the first locking cover 31 is covered on the first locking side 331 of the isolation portion 33, the first locking cover 31 and the isolation portion 33 can apply appropriate pressure to the warp yarn section 10 to generate appropriate friction between the first locking cover 31 and the warp yarn section 10 and between the isolation portion 33 and the warp yarn section 10, so that the locking unit 30 is reliably locked to the warp yarn section 10.
Preferably, the first locking cover 31 and the isolation portion 33 may be made of a material having a slight deformation capability, such as rubber, so that when the first locking cover 31 and the isolation portion 33 lock the warp yarn section 10, the first locking cover 31 and the isolation portion 33 can apply appropriate pressure to the warp yarn section 10 to generate appropriate frictional force between the first locking cover 31 and the warp yarn section 10 and between the isolation portion 33 and the warp yarn section 10 to reliably lock the locking unit 30 to the warp yarn section 10 and prevent the warp yarn section 10 from being damaged by excessive pressure.
Accordingly, the spacer 33 has a second positioning groove 334, the second positioning groove 334 is disposed on the second locking side 332, the second locking cover 32 has a second receiving groove 321, wherein when the second locking cover 32 is covered on the second locking side 332 of the spacer 33, the position of the second receiving groove 321 of the second locking cover 32 corresponds to the position of the second positioning groove 334 of the spacer 33, so as to form a second threading channel 35 of the locking unit 30 for receiving the weft thread segment 20. The diameter of the second threading channel 35 of the locking unit 30 is equal to or slightly smaller than the diameter of the weft thread section 20, so that after the second locking cover 32 is covered on the second locking side 332 of the partition 33, the second locking cover 32 and the partition 33 can apply appropriate pressure to the weft thread section 20 to generate appropriate friction between the second locking cover 32 and the weft thread section 20 and between the partition 33 and the weft thread section 20 to reliably lock the locking unit 30 to the weft thread section 20.
Preferably, the second locking cover 32 may also be made of a material with a slight deformation capability, such as rubber, so that when the second locking cover 32 and the spacer 33 lock the weft thread segment 32, the second locking cover 32 and the spacer 33 can apply pressure to the weft thread segment 20 to generate appropriate friction between the second locking cover 32 and the weft thread segment 20 and between the spacer 33 and the weft thread segment 20 to enable the locking unit 30 to reliably lock the weft thread segment 20 and prevent the weft thread segment 20 from being damaged by being pressed excessively.
That is, after the first locking cover 31 is covered on the first locking side 331 of the partition 33, a portion of the warp yarn section 10 is held in the first threading channel 34 of the locking unit 30, and the first locking cover 31 and the partition 33 provide a clamping force to clamp the warp yarn section 10 to reliably lock the locking unit 30 to the warp yarn section 10, and accordingly, after the second locking cover 32 is covered on the second locking side 332 of the partition 33, a portion of the weft yarn section 20 is held in the second threading channel 35 of the locking unit 30, and the second locking cover 32 and the partition 33 provide a clamping force to clamp the weft yarn section 20, so that the locking unit 30 locks and physically separates the warp yarn section 10 and the weft yarn section 20.
Turning now to fig. 4 to 6, the first locking cap 31 further has at least one first through hole 312, the second locking cap 32 further has at least one second through hole 322, the partition 33 further has at least one partition through hole 335, and after the first locking cap 31 and the second locking cap 32 are respectively covered on the first locking side 331 and the second locking side 332 of the partition 33, the first through hole 312 of the first locking cap 31, the partition through hole 335 of the partition 33, and the second through hole 322 of the second locking cap 32 correspond and communicate with each other. The locking unit 30 further includes at least one screw assembly 36, the screw assembly 36 includes a screw 361 and a nut 362, one end of the screw 361 is screwed with the nut 362 after sequentially passing through the second through hole 322 of the second locking cover 32, the partition through hole 335 of the partition 33 and the first through hole 312 of the first locking cover 31, so that the screw 361 and the nut 362 are mutually matched to fix the first locking cover 31, the partition 33 and the second locking cover 32, and the first locking cover 31 and the partition 33 provide a proper clamping force for locking the locking unit 30 to the warp section 10 and the second locking cover 32 and the partition 33 provide a proper clamping force for locking the locking unit 30 to the weft section 20. It can be understood that the magnitude of the clamping force generated between the first locking cover 31 and the partition 33 and the magnitude of the clamping force generated between the second locking cover 32 and the partition 33 can be controlled by controlling the installation positions of the screw 361 and the nut 362.
In some specific examples of the optical fiber net 100 of the present invention, the first locking cover 31 has four first through holes 312, the four first through holes 312 are disposed at an edge of the first locking cover 31 in a spaced manner, the second locking cover 32 has four second through holes 322, the four second through holes 322 are disposed at an edge of the second locking cover 32 in a spaced manner, the spacer 33 has four spacer through holes 335, the four spacer through holes 335 are disposed at an edge of the spacer 33 in a spaced manner, and after the first locking cover 31 and the second locking cover 32 are respectively disposed at the first locking side 331 and the second locking side 332 of the spacer 33, the four first through holes 312 of the first locking cover 31, the four spacer through holes 335 of the spacer 33, and the four second through holes 322 of the second locking cover 32 correspond to one another. The locking unit 30 includes four screw assemblies 36, and the screw 361 of each screw assembly 36 sequentially passes through each second through hole 322 of the second locking cover 32, each partition through hole 335 of the partition 33, and each first through hole 312 of the first locking cover 31, respectively, so that the first locking cover 31, the partition 33, and the second locking cover 32 are fixed by the four screw assemblies 36. With such a structure as described above, the four screw assemblies 36 allow the first locking cover 31 and the spacer 33 to provide an even clamping force in the entire circumferential direction, so that not only the locking unit 30 reliably locks the warp thread section 10, but also the portion of the warp thread section 10 held in the first threading channel 34 of the locking unit 30 is subjected to an even pressure to function as a protector for the warp thread section 10, and accordingly, the four screw assemblies 36 allow the second locking cover 32 and the spacer 33 to provide an even clamping force in the entire circumferential direction, so that not only the locking unit 30 reliably locks the weft thread section 20, but also the portion of the weft thread section 20 held in the second threading channel 35 of the locking unit 30 is subjected to an even pressure to function as a protector for the weft thread section 20.
Turning now to fig. 6 to 8, the locking unit 30 further has a first glue filling space 37 and a second glue filling space 38, wherein the first glue filling space 37 is formed between the first locking cover 31 and the partition 33, a portion of the warp yarn section 10 is exposed to the first glue filling space 37 of the locking unit 30, after glue is filled into the first glue filling space 37 and cured, the glue can bond the warp yarn section 10, the first locking cover 31 and the partition 33 to further securely lock the locking unit 30 and the warp yarn section 10, wherein the second glue filling space 38 is formed between the second glue filling cover 32 and the partition 33, a portion of the weft yarn section 20 is exposed to the second glue filling space 38 of the locking unit 30, after glue is filled into the second glue filling space 38 and cured, the glue can bond the locking unit 20, the second locking cover 32 and the partition 33 to further securely lock the locking unit 30 and the warp yarn section 10.
That is, the locking unit 30 and the warp yarn section 10 are locked to each other not only based on the frictional force generated between the first locking cover 31 and the warp yarn section 10 and the frictional force generated between the isolating portion 33 and the warp yarn section 10, but also based on the adhesive force provided by the glue, so that the locking unit 30 and the warp yarn section 10 are reliably locked. The locking unit 30 and the weft thread segment 20 are locked to each other not only based on the frictional force generated between the second locking cover 32 and the weft thread segment 20 and the frictional force generated between the spacer 33 and the weft thread segment 20, but also based on the adhesive force provided by the glue, so that the locking unit 30 and the weft thread segment 20 are reliably locked.
In this particular example of the optical fiber net 100 of the present invention, all crossing positions of the warp thread segments 10 and the weft thread segments 20 are provided with one of the locking units 30, so that the optical fiber net 100 is not deformed during the use of the optical fiber net 100, so that the optical fiber net 100 is always kept regular, which is important for positioning the damaged position of the optical fiber net 100 during the use.

It is worth mentioning that when the first locking cap 31 is pressed toward the isolating portion 33 to allow the first locking protrusion 313 of the first locking cap 31 to extend into the first locking hole 337 of the isolating portion 33, the inner wall of the isolating portion 33 for forming the first locking hole 337 presses the first locking protrusion 3131 of the first locking cap 313 of the first locking cap 31 to deform the first locking protrusion 313 of the first locking cap 31 in a direction away from the first locking protrusion 3131 to accumulate elastic potential energy, and when the first locking protrusion 3131 of the first locking protrusion 313 of the first locking cap 31 exposes the first locking protrusion 337 of the isolating portion 33, the first locking protrusion 313 of the first locking cap 31 automatically restores to an original shape to allow the first locking protrusion 3131 of the first locking protrusion 313 of the first locking cap 31 to automatically lock the isolating portion 33, thereby setting the first locking cap 31 to the first locking side 331 of the isolating portion 33.

It should be noted that when the second locking cap 32 is pressed toward the isolating portion 33 to allow the second lock 323 of the second locking cap 32 to extend into the second lock hole 3310 of the isolating portion 33, the inner wall of the isolating portion 33 for forming the second lock hole 3310 presses the second lock protrusion 3231 of the second lock 323 of the second locking cap 32, so that the second lock 323 of the second locking cap 32 deforms toward a direction away from the second lock protrusion 3231 to accumulate elastic potential energy, and when the second lock protrusion 3231 of the second lock 323 of the second locking cap 32 is exposed out of the second lock hole 3310 of the isolating portion 33, the second lock protrusion 323 of the second locking cap 32 automatically restores to the original shape to allow the second lock protrusion 3231 of the second lock 323 of the second locking cap 32 to automatically lock the isolating portion 33, thereby allowing the second lock cap 32 to be disposed at the isolating side of the second locking cap 33.
