Technical Field

[0001] The embodiments disclosed herein relate to the field of optical cable junction box technology, and more specifically, to an expandable optical cable junction box. Background Technology

[0002] Fiber optic splice box is a common name; its technical name is fiber optic splice box, also known as fiber optic splice package, fiber optic joint package, and cannon. It belongs to the mechanical pressure sealing joint system and is a splicing protection device that provides optical, sealing, and mechanical strength continuity between adjacent fiber optic cables. It is mainly suitable for various laying methods of fiber optic cables, such as aerial, duct, and direct burial.

[0003] The existing optical cable splice boxes have limited internal space. When more components are needed inside the optical cable splice box, it is difficult to expand the internal space because most of the existing optical cable splice boxes are fixed. The limited internal space of the optical cable splice box cannot accommodate more components, which increases the limitation of the use of the optical cable splice box. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide an expandable optical cable junction box, which solves the technical problem that the limited space inside a fixed optical cable junction box in the prior art makes it difficult to accommodate more components, thereby increasing the limitation of the use of the optical cable junction box.

[0005] According to one aspect, at least one embodiment of this disclosure provides an expandable optical cable junction box, including an upper optical cable junction box and a lower optical cable junction box, and further including: an expansion box, a lifting box, a drive mechanism, and a limiting mechanism. The expansion box is connected to the top of the lower optical cable junction box via a connecting plate, and the lifting box is connected to the bottom of the upper optical cable junction box via a connecting plate. The expansion box has a sliding groove that matches the lifting box, and the lifting box is slidably connected in the sliding groove. Two drive mechanisms are provided, and the two drive mechanisms are respectively disposed on both sides of the expansion box, which can drive the lifting box to move up and down in the sliding groove. Two limiting mechanisms are provided, and the two limiting mechanisms are respectively disposed on both sides of the expansion box, which are used to fix and limit the displacement of the lifting box.

[0006] In order to drive the lifting box to move up and down within the expansion box, the driving mechanism includes a rack and a drive gear. The rack is fixedly connected to one side of the lifting box, and the drive gear is rotatably connected within the expansion box. The drive gear meshes with the rack.

[0007] To increase the stability of the rack during movement, the expansion box is provided with a sliding groove and a rotating groove, which are connected. The rack is slidably connected in the sliding groove, and the drive gear is rotatably connected in the rotating groove.

[0008] In order to rotate the drive gear, a rotating rod is fixedly connected to one side of the drive gear, and a torsion wheel is fixedly connected to the other end of the rotating rod.

[0009] In order to fix the lifting box after the height of the lifting box is adjusted, the limiting mechanism includes: a limiting screw and a limiting hole. The expansion box has a screw hole. The limiting screw is threaded into the screw hole. Multiple limiting holes are provided. All the multiple limiting holes are provided on one side of the lifting box, and one of the limiting holes corresponds to the screw hole. The limiting screw is inserted into one of the limiting holes.

[0010] In order to drive the limiting screw to rotate, a rotating wheel is fixedly connected to the other end of the limiting screw.

[0011] In order to limit the different heights of the lifting box, multiple limiting holes are arranged longitudinally on one side of the lifting box.

[0012] In order to provide ventilation and heat dissipation for the components, ventilation slots are provided on both the expansion box and the lifting box.

[0021] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0022] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0027] like Figures 1-4 The diagram illustrates an expandable optical cable junction box according to an embodiment of this disclosure. It includes an upper optical cable junction box 1 and a lower optical cable junction box 2, and further comprises an expansion box 3, a lifting box 5, a drive mechanism, and a limiting mechanism. Both the expansion box 3 and the lifting box 5 have ventilation slots 15. The expansion box 3 is connected to the top of the lower optical cable junction box 2 via a connecting plate 4, and the lifting box 5 is connected to the bottom of the upper optical cable junction box 1 via the connecting plate 4. The expansion box 3 has a sliding groove that matches the lifting box 5, and the lifting box 5 is slidably connected within the sliding groove. The drive mechanism has two... Two drive mechanisms are respectively set on both sides of the expansion box 3, which can drive the lifting box 5 to move up and down in the slide. Two limit mechanisms are provided, which are respectively set on both sides of the expansion box 3, and are used to fix and limit the displacement of the lifting box 5. Through the cooperation between the upper optical cable junction box 1, the lower optical cable junction box 2, the expansion box 3, the lifting box 5, the drive mechanism and the limit mechanism, the space between the upper optical cable junction box 1 and the lower optical cable junction box 2 can be expanded, which can accommodate more components and has lower usage limitations.

[0028] The drive mechanism includes a rack 6 and a drive gear 7. The rack 6 is fixedly connected to one side of the lifting box 5, and the drive gear 7 is rotatably connected inside the expansion box 3. The drive gear 7 meshes with the rack 6. The expansion box 3 has a sliding groove 8 and a rotating groove 9, which are connected. The rack 6 is slidably connected in the sliding groove, and the drive gear 7 is rotatably connected in the rotating groove 9. A rotating rod 10 is fixedly connected to one side of the drive gear 7, and a torsion wheel 11 is fixedly connected to the other end of the rotating rod 10. When the operator rotates the torsion wheel 11, the rotating rod 10 is driven to rotate. When the rotating rod 10 rotates, it drives the drive gear 7 to rotate. When the drive gear 7 rotates, it drives the rack 6 and the lifting box 5 to move up and down inside the expansion box 3, thereby opening up the upper optical cable connector box 1 and the lower optical cable connector box 2, and thus expanding the capacity between the upper optical cable connector box 1 and the lower optical cable connector box 2.

[0029] The limiting mechanism includes a limiting screw 12 and limiting holes 13. Multiple limiting holes 13 are arranged longitudinally on one side of the lifting box 5. The other end of the limiting screw 12 is fixedly connected to a rotating wheel 14. The expansion box 3 has a screw hole, and the limiting screw 12 is threaded into the screw hole. Multiple limiting holes 13 are provided, all of which are located on one side of the lifting box 5. One of the limiting holes 13 corresponds to the screw hole. The limiting screw 12 is inserted into one of the limiting holes 13. After the lifting box 5 is adjusted, the operator twists the rotating wheel 14 to drive the limiting screw 12 to rotate in the screw hole, thereby inserting the limiting screw 12 into the limiting hole 13 corresponding to the current height of the lifting box 5, thus fixing and limiting the height of the lifting box 5.

[0030] The working principle is as follows: When it is necessary to expand the capacity between the upper optical cable junction box 1 and the lower optical cable junction box 2, the operator rotates the torsion wheel 11 to drive the rotating rod 10 to rotate. When the rotating rod 10 rotates, it drives the drive gear 7 to rotate. When the drive gear 7 rotates, it drives the rack 6 and the lifting box 5 to move up and down within the expansion box 3, thereby opening up the upper optical cable junction box 1 and the lower optical cable junction box 2, thus expanding the capacity between them. After the lifting box 5 is adjusted, the operator twists the rotating wheel 14 to drive the limiting screw 12 to rotate in the screw hole, so that the limiting screw 12 is inserted into the limiting hole 13 corresponding to the current height of the lifting box 5, thereby fixing and limiting the height of the lifting box 5.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
