[0047] The present invention will be further described in detail below with reference to the accompanying drawings.

[0048] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0049] Example 1:

[0050] This embodiment relates to an optical fiber distribution box, as shown in the following figure. Figures 1-7 The system includes a housing, a rotating assembly 300, and a rotating connecting assembly. The housing contains a receiving cavity 110; the rotating assembly 300 is rotatably mounted within the receiving cavity 110 and is used for coiling optical fibers 800; the rotating connecting assembly is located between the housing and the rotating assembly 300, allowing the rotating assembly 300 to rotate relative to the housing. The optical fiber 800 is coiled on the rotating assembly 300. When cabling is required, the operator pulls one end of the optical fiber 800, causing the rotating assembly 300 to rotate relative to the housing, thus automatically laying the fiber. This reduces manual intervention in laying and organizing the fiber, allowing a single person to complete the cabling operation, saving labor costs and making the overall cabling process more convenient and simple. This optical fiber distribution box not only stores optical fibers 800 but also enables automatic cable laying.

[0051] Furthermore, the enclosure includes: an outer shell 100 and a base assembly 200. The outer shell 100 has a receiving cavity 110; the base assembly 200 is assembled in the receiving cavity 110; and a rotating connection assembly is disposed between the base assembly 200 and the rotating assembly 300.

[0052] Furthermore, referring to Figures 7-12 The rotating assembly 300 includes a first rotating disk 310 and a second rotating disk 320. The first rotating disk 310 has a first hollow structure 311 and is rotatably mounted on the base assembly 200. The second rotating disk 320 is mounted on the end of the first rotating disk 310 away from the base assembly 200. An annular protrusion 420 is provided on the inner peripheral wall of the first rotating disk 310. The outer wall of the first rotating disk 310 and the side of the second rotating disk 320 facing the outer wall of the first rotating disk 310 form an assembly space 330 for winding the optical fiber 800. The assembly space 330 provides a fixed winding space for the optical fiber 800, preventing the optical fiber 800 from becoming tangled. In this embodiment, the first rotating disk 310 and the second rotating disk 320 are detachably assembled. In some embodiments, the first rotating disk 310 and the second rotating disk 320 can be integrally formed.

[0053] Specifically, the first rotating disk 310 includes a rotating cylinder 312 and a first rotating ring 313. The top end of the rotating cylinder 312 abuts against the second rotating disk 320, and the other end is rotatably mounted on the base assembly 200; the first rotating ring 313 is mounted on the bottom end of the rotating cylinder 312; the end of the rotating cylinder 312 away from the base assembly 200 is used for mounting the second rotating disk 320; both the rotating cylinder 312 and the first rotating ring 313 are provided with a first hollow structure 311; specifically, an annular protrusion 420 is circumferentially arranged on the inner peripheral wall of the rotating cylinder 312; the outer peripheral sidewall of the rotating cylinder 312, the side of the first rotating ring 313 facing the second rotating disk 320, and the side of the second rotating disk 320 facing the first rotating ring 313 form an assembly space 330 for mounting the optical fiber 800. The rotating cylinder 312 serves as the main body of the rotating assembly 300. When an operator pulls one end of the optical fiber 800, the rotating cylinder 312 rotates relative to the base assembly 200, driving the first rotating ring 313 and the second rotating disk 320 to assemble, thereby achieving automatic cable feeding. In this embodiment, the first rotating ring 313 and the rotating cylinder 312 are integrally formed.

[0054] Furthermore, referring to Figures 7-12The second rotating disk 320 is detachably mounted on one end of the rotating cylinder 312. The second rotating disk 320 has a first engaging post 510 extending towards the first rotating disk 310; the first rotating disk 310 has a first engaging hole 520 that mates with the first engaging post 510. Specifically, the side of the second rotating disk 320 facing the rotating cylinder 312 has a first engaging post 510 extending towards the rotating cylinder 312; the rotating cylinder 312 has a first engaging hole 520 that mates with the first engaging post 510. The first engaging post 510 and the first engaging hole 520 mate to achieve the engaging engagement of the first rotating disk 310 and the second rotating disk 320, specifically achieving the engaging engagement of the rotating cylinder 312 and the second rotating disk 320, facilitating disassembly, assembly, and maintenance. In this embodiment, multiple first engaging posts 510 and multiple second engaging holes 540 are provided, and they correspond one-to-one, to achieve a secure assembly of the second rotating disk 320 and the rotating cylinder 312. Specifically, four first latching posts 510 and four second latching holes 540 are provided. In some embodiments, one or six first latching posts 510 and two second latching holes 540 may also be provided. In some embodiments, the second rotating disk 320 and the rotating cylinder 312 may also be magnetically attached.

[0055] In this embodiment, refer to Figures 8-12 The base assembly 200 includes a base plate 210 and a rotating seat 220. The base plate 210 is assembled within the receiving cavity 110; the rotating seat 220 is assembled on the base plate 210, with one end for rotation of the first rotating disk 310; one end of the rotating seat 220 is located within the first hollow structure 311. An arc-shaped groove 410 is provided on the side of the rotating seat 220 facing the first rotating disk 310. Specifically, the arc-shaped groove 410 is provided on the side of the rotating seat 220 facing the rotating cylinder 312. That is, when the operator pulls one end of the optical fiber 800, the rotating cylinder 312 and the first rotating ring 313 drive the second rotating disk 320 to rotate relative to the rotating seat 220. Specifically, the base plate 210 is snap-fitted onto the inner wall of the outer casing 100.

[0056] Furthermore, referring to Figures 8-12The rotating connection assembly includes an annular protrusion 420 and an arc-shaped groove 410. The annular protrusion 420 is circumferentially disposed on the rotating assembly 300 and protrudes towards one end of the base assembly 200; the arc-shaped groove 410 is disposed on the side of the base assembly 200 facing the rotating assembly 300 and is used to engage with the annular protrusion 420; one or more arc-shaped grooves 410 are provided. Specifically, the annular protrusion 420 is circumferentially disposed on the inner circumferential wall of the rotating cylinder 312, and the arc-shaped groove 410 is disposed on the side of the rotating seat 220 facing the rotating cylinder 312. During the rotation of the rotating cylinder 312 relative to the rotating seat 220, the engagement of the annular protrusion 420 and the arc-shaped groove 410 neither hinders the rotation of the rotating cylinder 312 nor prevents large radial wobble of the rotating cylinder 312 during rotation, and also limits the rotation of the rotating cylinder 312, preventing the rotating cylinder 312 from disengaging from the rotating seat 220 during rotation. Specifically, in this embodiment, the rotating seat 220 facing the rotating cylinder 312 is provided with a first arc-shaped protrusion 430 and a second arc-shaped protrusion 440; the first arc-shaped protrusion 430 and the second arc-shaped protrusion 440 are parallel in the vertical direction and spaced apart. The first arc-shaped protrusion 430 is located on the side closer to the second rotating disk 320, and the second arc-shaped protrusion 440 is located on the side closer to the base plate 210. The first arc-shaped protrusion 430, the second arc-shaped protrusion 440, and the outer wall of the rotating seat 220 form an arc-shaped groove 410. In this embodiment, multiple first arc-shaped protrusions 430 and multiple second arc-shaped protrusions 440 are provided, and thus multiple arc-shaped grooves 410 are also provided. The multiple arc-shaped grooves 410 cooperate with the annular protrusion 420 to ensure the force balance during rotation, thereby ensuring that the rotation of the rotating cylinder 312 is more stable and smooth. In this embodiment, the first arc-shaped protrusion 430 and the second arc-shaped protrusion 440 are not in a one-to-one correspondence. Specifically, four first arc-shaped protrusions 430 and twelve second arc-shaped protrusions 440 are arranged around the circumference. The first arc-shaped protrusions 430, the second arc-shaped protrusions 440, and the outer wall of the rotating seat 220 form four arc-shaped grooves 410. The remaining second arc-shaped protrusions 440 are used to prevent the rotating cylinder 312 from falling towards the base plate 210. In other embodiments, the first arc-shaped protrusion 430 may also have six circumferences, the second arc-shaped protrusions 440 may have eight circumferences, and the first arc-shaped protrusions 430, the second arc-shaped protrusions 440, and the outer wall of the rotating seat 220 may form six arc-shaped grooves 410. In some embodiments, only one first arc-shaped protrusion 430 and one second arc-shaped protrusion 440 may be provided, and thus only one arc-shaped groove 410 may be provided. In this embodiment, the rotating base 220 is provided with a plurality of spaced-apart hollow structures 221.

[0057] In this embodiment, the rotating seat 220 is detachably mounted on the base plate 210. Specifically, refer to... Figures 8-9The rotating base 220 is provided with a second locking post 530 extending towards the base plate 210; the base plate 210 has a second locking hole 540 through which the second locking post 530 passes; the second locking post 530 passes through the second locking hole 540 to lock onto the bottom surface of the base plate 210. The second locking hole 540 and the second locking post 530 cooperate to realize the locking engagement between the rotating base 220 and the base plate 210, facilitating disassembly and maintenance. In this embodiment, multiple second locking holes 540 and second locking posts 530 are provided, and they correspond one-to-one to achieve a stable assembly of the rotating base 220 and the base plate 210. Specifically, four second locking holes 540 and second locking posts 530 are provided. In some embodiments, one or six second locking holes 540 and second locking posts 530 may also be provided. In some embodiments, the rotating base 220 and the base plate 210 may also be magnetically assembled.

[0058] Furthermore, referring to Figures 8-12 The second rotating disk 320 includes a second rotating ring 321 and an extension plate 322. One side of the second rotating ring 321 abuts against the first rotating disk 310. One end of the extension plate 322 is connected to the inner wall of the second rotating ring 321, and the other end extends downwards at an incline towards the base plate 210. A through hole 3221 is provided at the bottom end of the extension plate 322. Specifically, one side of the second rotating ring 321 abuts against the rotating cylinder 312 in the first rotating disk 310. The rotating seat 220 is provided with a second hollow structure 222. A mounting post 230 is provided on the base plate 210. The mounting post 230 is located inside the second hollow structure 222 and extends vertically away from the base plate 210. The mounting post 230 has a mounting channel 231 inside, and a mounting hole 232 communicating with the mounting channel 231 is provided at its free end. Specifically, the other end of the extension plate 322 extends downwards at an incline towards the mounting post 230, and the extension plate 322 is conical in shape. Mounting hole 232 is connected to through hole 3221.

[0059] Reference Figures 7-12The fiber optic distribution box also includes a locking member 610 and a limiting member 620 located within the mounting channel 231. One end of the limiting member 620 protrudes from the side of the extension plate 322 facing away from the mounting post 230, and the fastening end 621 passes through the through hole 3221 and the mounting hole 232 to cooperate with the locking member 610; the limiting member 620 is used to limit the extension plate 322 and allow the extension plate 322 to rotate and be fitted. In this embodiment, the mounting hole 232, the through hole 3221, and the mounting channel 231 are coaxially arranged. The limiting member 620 passes through the through hole 3221 and cooperates with the locking member 610 located in the mounting channel 231 to achieve a stable connection between the extension plate 322 and the mounting post 230, thereby securing the first rotating disk 310 firmly onto the base plate 210. Since the first rotating disk 310 is mounted on the second rotating disk 320, the rotating assembly 300 can ultimately be stably locked onto the base plate 210, preventing the rotating assembly 300 from shifting or even detaching from the base plate 210 during rotation. Furthermore, it should be noted that the extension plate 322 is rotatably sleeved on the limiting member 620 and located at the end away from the fastening end 621, ensuring that the extension plate 322 can rotate normally relative to the limiting member 620. The side of the extension plate 322 facing the mounting post 230 is positioned opposite to the mounting post 230, but they do not abut against each other. Additionally, a gasket is provided between the limiting member 620 and the side of the extension plate 322 facing away from the mounting post 230. In this embodiment, the limiting member 620 is a screw, and the locking member 610 is a nut.

In this embodiment, multiple snap-fit ​​elements 700 are provided. In some embodiments, a single snap-fit ​​element 700 may also be provided.

[0061] Furthermore, referring to Figures 1-7The enclosure 100 includes a bottom shell 120 for assembling the base assembly 200 and a flip cover 130 rotatably mounted on one side of the bottom shell 120; the bottom shell 120 and the flip cover 130 form a receiving cavity 110. A sealing ring is also provided between the bottom shell 120 and the flip cover 130 to ensure the sealing performance when the flip cover 130 is closed on the bottom shell 120. Multiple screw posts 920 are provided on one side of the enclosure 100; the screw posts 920 have screw holes 921 at the end facing the receiving cavity 110 for mounting cable clamps, fiber storage trays, fixing clips, etc., thus meeting the needs of cabling operators for flexibly fixing optical cables and fiber optic adapters (fiber optic flanges). The enclosure 100 has fiber optic inlet / outlet holes 121 for the entry and exit of optical fibers 800, allowing the optical fiber 800 to be directly introduced from the back of the bottom shell 120. The fiber optic distribution box also includes a sealing gasket 910 for blocking the fiber optic inlet / outlet hole 121; the fiber optic cable 800 passes through the groove of the sealing gasket 910 to enter the receiving cavity 110.

The rotating seat 220 does not have a second locking post 530, the base plate 210 does not have a second locking hole 540, and the rotating seat 220 does not have a hollow structure 221. In this embodiment, the first arc-shaped protrusion 430 and the second arc-shaped protrusion 440 are in a one-to-one correspondence. Four first arc-shaped protrusions 430 and four second arc-shaped protrusions 440 are arranged around their circumference. The first arc-shaped protrusions 430, the second arc-shaped protrusions 440, and the outer wall of the rotating seat 220 form four arc-shaped grooves 410. In other embodiments, the first arc-shaped protrusions 430 may also have six circumferentially arranged protrusions, and the second arc-shaped protrusions 440 may also have six circumferentially arranged protrusions.
