Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and in particular to an optical cable junction box. Background Technology

[0002] Optical fiber distribution boxes are the distribution and splitting devices for user terminals in FTTH systems. They can perform functions such as fiber splicing, distribution, and scheduling, and can also serve as splitting nodes for long-distance fiber optic transmission. Optical fiber distribution boxes play a vital role in fiber optic networks, used for the distribution, connection, and management of optical cables. They provide efficient and reliable fiber optic access solutions and support the expansion and upgrading of fiber optic communication systems.

[0003] Existing optical cable distribution boxes mostly rely on a single clamp or hook design for fixing optical cables, making it difficult to fix the optical cables through adjustable winding methods. The optical cables are prone to slippage due to the lack of a stable limiting structure. At the same time, the components used to adjust the fixing status of the optical cables (such as the adjusting slide) lack convenient unlocking and limiting mechanisms. Adjustment requires additional tools or complex operations to unlock them. To address the above problems, an optical cable distribution box is proposed. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Reference Figures 1-5 The optical cable distribution box shown includes a box body 1, which is equipped with multiple sets of winding mechanisms. The winding mechanisms are used to wind up and limit the cable to prevent slippage. The box body 1 is also equipped with a limiting mechanism to limit the winding mechanisms. The winding mechanism includes a winding roller 2 and a disc 3. A mounting shaft is rotatably mounted on the bottom inner wall of the housing 1. The winding roller 2 is fixedly sleeved on the mounting shaft. The disc 3 is rotatably mounted on the bottom inner wall of the housing 1. Two winding wheels 7 are slidably mounted on the top of the disc 3 through an extrusion assembly. A transmission cavity is opened at the bottom of the housing 1. A rotating shaft 8 is rotatably mounted on the bottom inner wall of the transmission cavity. The top of the rotating shaft 8 is fixedly connected to the bottom of the disc 3. The limiting mechanism includes a gear 9 and a rack 11. The gear 9 is fixedly sleeved on the rotating shaft 8. A rectangular slide plate 10 is slidably installed in the transmission cavity. The rack 11 is fixedly installed on the side of the rectangular slide plate 10. The gear 9 and the rack 11 are meshed and installed. A snap-fit ​​component is provided on the rectangular slide plate 10.

[0019] With the above structure, in use, the two winding wheels 7 are first moved in opposite directions to pull the optical cable out of the winding roller 2 and place it between the two winding wheels 7. Then, by sliding the rectangular slide plate 10, the straight rack 11 is driven to mesh with the gear 9, so that the gear 9 drives the disc 3 to rotate, which in turn drives the two winding wheels 7 to rotate, winding the optical cable into an S-shape, thereby fixing it and preventing it from slipping.

[0020] like Figure 3 As shown, the extrusion assembly includes two guide shafts 5. Two grooves are opened at the top of the disc 3. The two ends of the two guide shafts 5 are respectively fixedly installed on the opposite inner walls of the two grooves. A square slider 4 is slidably installed on each of the two guide shafts 5. An elastic unit is provided on the side of each of the two square sliders 4. Two winding wheels 7 are respectively fixedly installed on the top of the two square sliders 4. In this way, the guiding function of the two guides 5 can limit the square slider 4 and prevent it from falling off.

[0021] Specifically, when the square slider 4 slides, the guide shaft 5 can limit the square slider 4 to prevent it from falling off.

[0022] like Figure 3 As shown, the elastic unit includes a compression spring 6, which is sleeved on the guide shaft 5. One end of the compression spring 6 is installed on the side of the square slider 4 through a damper, and the damper is slidably sleeved on the guide shaft 5. The other end of the compression spring 6 is fixedly installed on the inner wall of the side of the slide groove. With this configuration, the elastic action of the compression spring 6 can drive the winding wheel 7 to achieve the reset function when the limit on the winding wheel 7 is released.

[0023] Specifically, when the two winding wheels 7 move in opposite directions, they drive the two square sliders 4 to move synchronously, squeezing the two compression springs 6. When the limit on the square sliders 4 is released, the elasticity of the springs allows the two square sliders 4 to achieve the reset function.

[0024] like Figure 5As shown, the snap-fit ​​assembly includes two pressing plates 12. A rectangular hole is provided on the top inner wall of the transmission cavity. Two pressing grooves are provided on the top of the rectangular slide plate 10. The two pressing plates 12 are slidably installed in the two pressing grooves respectively. Sliding holes are provided on the side inner walls of the two pressing grooves. Sliding pins 13 are provided in the two sliding holes. Return springs 14 are sleeved on the two pins 13 respectively. One end of the two pins 13 is fixedly connected to the side of the two pressing plates 12 respectively. The opposite inner walls of the transmission cavity are provided with pin connection units that are adapted to the two pins 13. With this configuration, the two pins 13 can be driven to move synchronously by sliding the two pressing plates 12, which facilitates the sliding function of the rectangular slide plate 10.

[0025] Specifically, when the rectangular slide plate 10 needs to be slid, the two pressing plates 12 are slid, thereby driving the two pins 13 to move synchronously, releasing the engagement with the pin connection unit, and thus enabling the rectangular slide plate 10 to achieve the movement function.

[0026] like Figure 5 As shown, the pin connection unit includes four pin slots 15, which are respectively opened on the opposite inner walls of the transmission cavity. The four pin slots 15 are adapted to two pins 13. With this arrangement, the pin slots 15 can be used to limit the pin 13 through the snap-fit ​​function between the pin 13 and the pin slots 15.

[0027] Specifically, when the pin 13 slides to the appropriate position, the elastic action of the return spring 14 can drive the pin 13 to return to its original position, thereby realizing the pin connection function with the pin groove 15 and thus limiting its movement.

[0028] like Figure 1 As shown, multiple cable routing holes 16 are provided on the inner walls of the housing 1. This arrangement allows optical cables to pass through the cable routing holes 16 easily.

[0029] Specifically, the multiple cable routing holes 16 facilitate the insertion and exit of optical cables through the cable routing holes 16.

[0030] like Figure 1 As shown, a cover 17 is hinged to the top of the box 1. The top of the cover 17 is provided with a groove. This design allows the cover 17 to seal the box 1 and prevent dust from entering.

[0031] Specifically, by closing the lid 17, the interior of the box 1 can be sealed to prevent dust from entering and causing damage.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
