One of the fixed limiting member and the movable limiting member has a limiting groove, and the other has a limiting protrusion. The loose fiber bundle passes through the limiting groove, and the limiting protrusion can extend into the limiting groove to press the loose fiber bundle against the limiting groove.

[0031] like Figures 1-5 As shown, this embodiment provides a measuring fixture for the cross-sectional area of a loose fiber bundle, used to assist a vernier caliper 100 in measuring the cross-sectional area of a loose fiber bundle 300. The vernier caliper 100 includes a caliper body 101, a fixed caliper foot 102, and a movable caliper foot 103. The fixed caliper foot 102 is fixedly connected to one end of the caliper body 101, and the movable caliper foot 103 is slidably connected to the caliper body 101. The measuring fixture for the cross-sectional area of the loose fiber bundle includes a fixed limiting member 1 and a movable limiting member 2. The fixed limiting member 1 is configured with... The fixed locking foot 102 is provided with the movable locking foot 103, and the movable locking foot 103 can move synchronously with the movable locking foot 103. One of the fixed locking foot 1 and the movable locking foot 2 is provided with a limiting groove 11, and the other is provided with a limiting protrusion 21. The loose fiber bundle 300 passes through the limiting groove 11. The limiting protrusion 21 can extend into the limiting groove 11 to press the loose fiber bundle 300 against the limiting groove 11. The degree of the vernier caliper 100 is read to obtain the cross-sectional area of the loose fiber bundle 300.
[0032] This fixture for measuring the cross-sectional area of loose fiber bundles is used to assist vernier calipers 100 in measuring the cross-sectional area of loose fiber bundles 300. The fixture includes a fixed limiting member 1 and a movable limiting member 2. The fixed limiting member 1 is located on the fixed foot 102 of the vernier calipers 100, and the movable limiting member 2 is located on the movable foot 103 of the vernier calipers 100 and can move synchronously with the movable foot 103. One of the fixed limiting member 1 and the movable limiting member 2 is provided with a limiting groove 11, and the other is provided with a limiting protrusion 21. The limiting protrusion 21 can extend into the limiting groove 11 to press the loose fiber bundle 300 passing through the limiting groove 11 against the limiting groove 11, and read the reading of the vernier calipers 100. Combined with the width of the limiting groove 11, the cross-sectional area of the loose fiber bundle 300 is calculated, thereby ensuring the amount of fiber used, ensuring the light intensity, and improving the product yield.
[0033] In this embodiment, a limiting groove 11 is provided on the fixed limiting member 1, and a limiting protrusion 21 is provided on the movable locking foot 103. The movable limiting member 2 moves with the movable locking foot 103 to be inserted into or disengaged from the limiting groove 11. The limiting groove 11 is provided on the fixed limiting member 1, and the loose fiber bundle 300 is installed in the fixed limiting member 1 to prevent the loose fiber bundle 300 from falling off when it is installed on the movable limiting member 2 and moves with the movable limiting member 2.
[0034] It should be noted that the length of the limiting groove 11 is defined along the depth direction of the limiting groove 11, and the distance between the two opposite sidewalls of the limiting groove 11 is defined as the width of the limiting groove 11. The loose fiber bundle 300 is pressed against the limiting groove 11 by the limiting protrusion 21. The cross-sectional area of the loose fiber bundle 300 is obtained by multiplying the length of the limiting groove 11 occupied by the loose fiber bundle 300 by the width of the limiting groove 11.
[0035] like Figure 6 As shown, the fixed limiting member 1 includes a first positioning plate 12 and a second positioning plate 13 arranged at intervals and in parallel. A first connecting structure 14 is provided between the first positioning plate 12 and the second positioning plate 13. The first connecting structure 14 and the first positioning plate 12 and the second positioning plate 13 form a first receiving groove 15 on the side facing the moving limiting member 2. A groove 16 is provided on the side of the first positioning plate 12 and the second positioning plate 13 facing the moving limiting member 2. The grooves 16 on the first positioning plate 12 and the second positioning plate 13 are arranged opposite to each other and are connected to the first receiving groove 15 to form a limiting groove 11. The limiting protrusion 21 includes a limiting plate 211 and protrusion structures 212 provided on both sides of the limiting plate 211. The limiting plate 211 can extend into the first receiving groove 15, and the two protrusion structures 212 can extend into the corresponding grooves 16. The above structure can bind the loose fiber bundle 300 within the limiting groove 11 through the limiting protrusion 21 and prevent the fiber from being cut by the shearing effect, thus effectively protecting the integrity of the fiber.
[0036] Preferably, the protruding structure 212 and the end of the limiting plate 211 facing the fixed limiting member 1 are flush, so that the end faces of the protruding structure 212 and the limiting plate 211 simultaneously press against the loose fiber bundle 300, increasing the contact area between them and the loose fiber bundle 300, and effectively avoiding the shearing effect that cuts the fiber.
[0037] like Figure 6 As shown, the groove 16 includes a groove body 161 and a slot 162 connected to the groove body 161. The size of the slot 162 gradually decreases along the direction towards the bottom of the groove body 161, thus forming a flared structure. The slot 162 of the flared structure can guide the installation of the loose fiber bundle 300, so that the loose fiber bundle 300 can be installed more smoothly in the groove body 161.
[0038] In this embodiment, the bottom of the groove body 161 is a plane, and the opposite side walls of the groove body 161 are arranged in parallel. Figure 6 (The two side walls of the groove body 161 are arranged parallel in the vertical direction). The above structure allows for easy determination of the distance between the relative side walls of the groove body 161. Then, by comparing the readings of the vernier caliper 100 before and after installing the loose fiber bundle 300, the cross-sectional area of the loose fiber bundle 300 can be calculated. In other embodiments, the vernier caliper 100 is an electronic vernier caliper. It is zeroed before installing the loose fiber bundle 300 (at which point it is not necessary to read the degree reading before installation), and the reading is taken after installation. The cross-sectional area of the loose fiber bundle 300 is obtained by multiplying the reading by the distance between the relative side walls of the groove body 161.
[0039] like Figure 6 As shown, the first connecting structure 14, the first positioning plate 12, and the second positioning plate 13 form a second receiving groove 17 on the side opposite to the moving limiting member 2. The fixing foot 102 can extend into the second receiving groove 17 and connect with the fixing limiting member 1. The setting of the second receiving groove 17 can enhance the connection effect between the fixing foot 102 and the fixing limiting member 1.
[0040] Optionally, a first threaded hole 18 is provided on the first positioning plate 12 and / or the second positioning plate 13, through which a first fixing member 19 passes and is threadedly connected to the first threaded hole 18 to abut against the fixing foot 102. In this embodiment, as shown... Figure 7 As shown, the second positioning plate 13 is provided with two first threaded holes 18. The first fixing member 19 is threadedly connected to the first threaded holes 18 and abuts against the fixing foot 102, thereby connecting the fixing foot 102 to the fixing limiting member 1. In other embodiments, the first threaded holes 18 can also be provided on the first positioning plate 12. The number of first threaded holes 18 is not limited to two, but can also be one, three or more.
[0041] In other embodiments, the fixing pin 102 and the fixing limiting member 1 are not limited to the above-described fixing methods. Corresponding first fixing holes can be provided on the first positioning plate 12 and the second positioning plate 13. A second fixing member passes through the corresponding first fixing hole and the fixing pin 102 to connect the fixing pin 102 and the fixing limiting member 1. All of the above connection methods can achieve a secure fixation between the fixing pin 102 and the fixing limiting member 1. Of course, other methods can also be used to connect the fixing pin 102 and the fixing limiting member 1, such as snap-fit or plug-in connections, as long as the connection between the fixing pin 102 and the fixing limiting member 1 can be achieved.
[0042] like Figure 6As shown, the movable limiting member 2 includes a movable limiting body 22, which includes two movable limiting plates 221 arranged at intervals and in parallel. One end of the two movable limiting plates 221 is connected by a second connecting structure 222 to form a third receiving groove 223. A limiting protrusion 21 is disposed on the second connecting structure 222. The movable locking foot 103 can extend into the third receiving groove 223 and connect with the movable limiting body 22. The third receiving groove 223 enhances the connection effect between the movable locking foot 103 and the movable limiting body 22.
[0043] In this embodiment, one of the movable limiting plates 221 is provided with a second threaded hole 224. A third fixing member 225 passes through and is threaded into the second threaded hole 224 to abut against the movable locking foot 103. Figure 7 As shown, two second threaded holes 224 are provided, and the movable locking foot 103 is connected to the movable limiting body 22 through two third fasteners 225, thereby enhancing the connection effect. The number of second threaded holes 224 and third fasteners 225 is not limited to two, and the number can be set according to specific needs.
[0044] In other embodiments, the connection between the movable locking foot 103 and the movable limiting body 22 is not limited to the connection method described above. Alternatively, second fixing holes can be provided on the two movable limiting plates 221, and a fourth fixing member can pass through the corresponding second fixing holes and the movable locking foot 103 to connect the movable locking foot 103 to the movable limiting member 2. All of the above connection methods can achieve a secure fixation between the movable locking foot 103 and the movable limiting member 2. Of course, other methods can also be used to connect the movable locking foot 103 and the movable limiting member 2, such as snap-fit or plug-in connections, as long as the connection between the movable locking foot 103 and the movable limiting member 2 can be achieved.
[0045] The cross-sectional area of the loose fiber bundle 300 is obtained as follows: like Figure 2 As shown, push the vernier caliper 100 tight and read the reading 1 of the vernier caliper 100 at this time; like Figure 3 As shown, when the vernier caliper 100 is pulled out normally, the loose bundle of loose fiber optics 300 is inserted into the groove 162 of the groove 16 and the limiting protrusion 21 is pushed in. The free filaments of the remaining loose fiber optics will enter the limiting groove 11 along with the large inclined groove 162 of the groove 16. like Figure 4 As shown, push the moving limiter 2 to tighten and read the reading 2 of the vernier caliper 100. At this time, the length of the loose fiber bundle 300 is = reading 2 - reading 1. The width of the loose fiber bundle 300 is the distance between the upper and lower side walls of the groove 16. It is obtained by measurement. The cross-sectional area of the loose fiber bundle 300 at this time is calculated using the formula (length × width = unit area). By comparing it with the design area, the most suitable amount of loose fiber can be obtained.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
