Description
Technical Field
[0001] This application relates to the field of optical cable technology, and in particular to a modular optical cable junction box. Background Technology
[0002] An optical fiber junction box is a connection device that provides termination and patching for backbone optical cables and distribution layer optical cables. After the optical cable enters the junction box, it is fixed, terminated, and distributed. Then, jumpers are used to connect the backbone optical cable and the distribution layer optical cable. Optical fiber junction boxes are outdoor connection devices that must be waterproof, dustproof, insect-proof, rodent-proof, and highly resistant to impact damage. During installation, floor-mounted or wall-mounted models can be selected according to the actual situation.
[0003] Chinese patent publication number CN202533617U discloses an outdoor ground-mounted modular optical cable junction box, which mainly consists of an external base and a box body, and an internal optical cable installation device module, an optical cable splicing and fiber distribution module, a fiber distribution and fiber storage splicing coaxial disk module, an optical splitter module, and a direct fusion module.
[0004] When installing fiber optic junction boxes on a wall, holes and slots need to be drilled at the installation location, and mounting brackets, such as fixing rods, need to be installed on the wall. Then, holes need to be drilled in the box body, and the fixing rods need to be inserted into the holes for hanging. If the hole and slot positions are not accurate, the fiber optic junction box will not match the installation location, and the fiber optic junction box will not be able to be installed, which is a significant drawback. Utility Model Content
[0005] To facilitate the installation of optical cable junction boxes, this application provides a modular optical cable junction box.
[0006] The modular optical cable junction box provided in this application adopts the following technical solution:
[0007] A modular optical cable junction box includes a box body with mounting plates on both sides. An adjusting rod is threadedly connected to each mounting plate and is positioned along the length of the box body. A limiting plate is located at the end of the adjusting rod away from the mounting plate, and the limiting plate is rotatably connected to the adjusting rod. The limiting plate is mounted on the box body. A hanging plate is threadedly connected to the adjusting rod. A slider is located on the side wall of the hanging plate. A slide rail is located on the side wall of the box body and is positioned along the length of the box body. The slider is inserted into the slide rail and slides in cooperation with it. A mounting hole is provided on the hanging plate for inserting a fixing rod.
[0008] By adopting the above technical solution, during use, the operator rotates the adjusting rod, and the hanging plate is threadedly connected to the adjusting rod. Under the guidance of the slider and the slide rail, the hanging plate moves up and down, so that the operator can adjust the position of the hanging hole according to the position of the fixed rod. After the adjustment is completed, the hanging hole is inserted into the fixed rod to realize the installation. Compared with the difficulty in accurately positioning the opening and slotting, this application is more convenient and applicable, and facilitates the installation of optical cable junction boxes.
[0009] Preferably, the side wall of the hanging hole is provided with an abutment groove, and an abutment plate is slidably disposed in the abutment groove. The bottom of the hanging plate is provided with a first frame, and an abutment rod is slidably disposed on the first frame. One end of the abutment rod is connected to the abutment plate. An abutment spring is connected to the first frame. A positioning ring is provided on the outer sleeve of the abutment rod. One end of the top spring is connected to the positioning ring. The abutment spring is sleeved on the outer sleeve of the abutment rod, and the abutment plate abuts against the fixing rod.
[0010] By adopting the above technical solution, during use, the operator first pulls the abutment rod, compressing the abutment spring, then inserts the fixing rod into the hook hole, releases the abutment rod, and the abutment spring returns to its original deformation, pushing the positioning ring upward, thereby causing the abutment rod to move upward. The abutment rod then drives the abutment plate to press against the fixing rod, further improving the stability of the box installation. Preferably, a rubber pad is provided on the side wall of the abutment plate, and the rubber pad abuts against the fixing rod.
[0011] By adopting the above technical solution, the rubber pad can increase the friction between the contact rod and the fixed rod, reducing the possibility of slippage.
[0012] Preferably, the hanging plate is provided with an indicator arrow, and the side wall of the box is provided with a scale bar arranged along the length of the box, with the indicator arrow pointing to the scale bar.
[0013] By adopting the above technical solution, when in use, rotating the adjusting rod causes the slider to move, which in turn moves the indicator arrow, pointing to the corresponding scale, so that the operator can clearly see the position of the two hanging plates and facilitate installation.
[0014] Preferably, the enclosure includes a junction box and a bottom support, wherein the junction box and the bottom support are detachably connected.
[0015] By adopting the above technical solution, when the box is hung on the wall, the bottom bracket can be removed to reduce the overall weight of the box and make it easier for the operator to move it. When it needs to be installed on the ground, the bottom bracket is connected to the box to support the box, reduce the direct contact between the box and the ground, and facilitate heat dissipation.
[0016] Preferably, multiple connecting blocks are provided on both sides of the junction box, and a snap-fit block is provided on the bottom support, which corresponds one-to-one with the multiple connecting blocks. The snap-fit block has a snap-fit groove for the connecting block to be inserted. The side wall of the snap-fit block has a rotating groove, which communicates with the snap-fit groove. A sliding rod is slidably provided on the snap-fit block. A hook plate is rotatably provided in the rotating groove. The side wall of the hook plate has a waist-shaped through groove. One end of the sliding rod is inserted into the rotating groove and passes through the waist-shaped through groove, and also passes through the snap-fit block. The connecting block has a hook groove. One end of the hook plate is inserted into the hook groove and abuts against the bottom wall of the hook groove. A fixing block is connected to the sliding rod. The fixing block is inserted into the waist-shaped through groove and fits against the side wall of the waist-shaped through groove.
[0017] By adopting the above technical solution, during connection, the operator inserts the snap-fit block into the snap-fit groove, rotates the hook plate, and inserts one end of the hook plate into the hook groove. Under the action of gravity, the hook plate moves downward, causing the sliding rod to slide vertically in the waist-shaped through groove until the hook plate and the hook groove are in contact. At this time, the operator pushes the sliding rod, which drives the fixed block to move, inserting the fixed block into the waist-shaped through groove and fitting it against the side wall of the waist-shaped through groove to achieve the limit, thereby realizing the connection between the bottom support and the junction box.
[0018] Preferably, a limiting ring plate is provided at one end of the sliding rod, and the limiting ring plate is threadedly connected to the sliding rod.
[0019] By adopting the above technical solution and setting a limiting ring, the possibility of the sliding rod falling off the locking block is reduced.
[0020] Preferably, the end of the fixing block facing the limiting ring plate is set with an inclined surface, and the inclined surface is set at an angle to the opposite side of the limiting ring plate in the vertical direction.
[0021] By adopting the above technical solution, a fixed block with an inclined surface is set, which allows the fixed block to enter the waist-shaped through groove more smoothly. This facilitates the sliding rod to drive the hook plate to rotate, so that the hook plate can be smoothly inserted into the hook groove of the connecting block to realize the connection between the junction box and the bottom bracket, thereby improving assembly efficiency.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The mounting plate is threadedly connected to the adjusting rod. Guided by the slider and slide rail, the mounting plate moves up and down, allowing the operator to adjust the position of the mounting hole according to the position of the fixed rod. After adjustment, the mounting hole is inserted into the fixed rod for installation. Compared to the difficulty in accurately positioning holes and slots, this application is more convenient and applicable, facilitating the installation of optical cable junction boxes. 2. The abutment plate and abutment spring at the mounting hole ensure that the abutment plate presses against the fixed rod, stabilizing the box. 3. The junction box body and bottom bracket are detachably connected, avoiding the disadvantages of one-piece molding and facilitating handling, installation, and maintenance.

Detailed Implementation
[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0031] This application mainly adopts a modular design and an adjustable mounting plate optical cable junction box solution, which achieves the effect of flexibly adjusting the optical cable mounting position and facilitating installation and maintenance. The following is a further detailed description of this application. Example
[0032] This application provides a modular optical cable junction box, referring to... Figure 1 and Figure 2 It includes components such as a housing, mounting plate 1, adjusting rod 2, limiting plate 3, hanging plate 5, fixing rod 01, contact plate 12, contact rod 11, contact spring 13, positioning ring 14, rubber pad 15, indicator arrow 16, scale bar 17, connecting block 20, snap-fit block 21, hook plate 24, sliding rod 25, fixing block 28, and limiting ring plate 29.
[0033] Reference Figure 1 and Figure 2 When mounting is required, first install the fixing rod 01 on the wall 02. You can first make a hole in the wall 02, insert the fixing rod 01, and then fix it with concrete. The mounting plate 1 is fixedly connected to both sides of the box. The adjusting rod 2 is rotatably connected to the mounting plate 1 and is set along the length of the box. The bottom of the adjusting rod 2 is provided with a handwheel 4. The limiting plate 3 is rotatably connected to the adjusting rod 2 and is connected to the end of the box away from the handwheel 4. The hanging plate 5 is threadedly connected to the adjusting rod 2.
[0034] Reference Figure 1 and Figure 2 The slider 6 is fixedly connected to the mounting plate 5. The side wall of the box is provided with a slide rail 7 corresponding to the two sliders 6. The slide rail 7 is set along the length of the box. The slider 6 is inserted into the slide rail 7 and slides with the slide rail 7. The mounting plate 5 is provided with a hanging hole 8 for the fixing rod 01 to be inserted.
[0035] Referring to the diagram, the cooperation between the slider 6 and the slide rail 7 on the mounting plate 5, as well as the threaded connection between the mounting plate 5 and the adjusting rod 2, forms a stable moving structure. When the adjusting rod 2 is rotated, because the adjusting rod 2 is rotatably connected to the mounting plate 1 and the limiting plate 3 restricts the axial movement of the adjusting rod 2, the mounting plate 5 moves along the thread direction of the adjusting rod 2. At the same time, the slider 6 slides within the slide rail 7, ensuring the stability and accuracy of the movement of the mounting plate 5. This structure allows the position of the mounting plate 5 to be flexibly adjusted.
[0036] Reference Figure 1 and Figure 2 The side wall of the mounting hole 8 is provided with an abutment groove 9 to accommodate the abutment plate 12. The abutment plate 12 can slide within the abutment groove 9 to abut and fix the fixing rod 01 inserted into the mounting hole 8. The bottom of the mounting plate 5 is provided with a first frame 10, which is a U-frame structure and is fixed to the bottom of the mounting plate 5 by welding or bolting. An abutment rod 11 is slidably mounted on the first frame 10. The abutment rod 11 is generally a cylindrical rod and can be made of metal. One end of the abutment rod 11 is connected to the abutment plate 12. When the abutment rod 11 moves, it will drive the abutment plate 12 to slide within the abutment groove 9. The abutment plate 12 is an arc-shaped plate, which can increase the contact area with the fixing rod 01.
[0037] Reference Figure 1 and Figure 2 A retaining spring 13 is connected to the first frame 10, and a positioning ring 14 is fitted over the retaining rod 11. The positioning ring 14 can be a ring-shaped metal plate, which is fixed to the retaining rod 11 by welding or snap-fitting. One end of the retaining spring 13 is connected to the positioning ring 14, and the other end is connected to the first frame 10. The retaining spring 13 is fitted over the retaining rod 11. When the fixing rod 01 is inserted into the hook hole 8, the fixing rod 01 will squeeze the retaining plate 12, causing the retaining plate 12 to compress the retaining spring 13. The elastic force generated by the retaining spring 13 will cause the retaining plate 12 to press against the fixing rod 01, thereby stabilizing the fixing rod 01.
[0038] Reference Figure 1 and Figure 2 A rubber pad 15 is provided on the side wall of the contact plate 12, and is fixed to the side wall of the contact rod 11 by adhesive. The rubber pad 15 has good flexibility and friction. When the contact rod 11 contacts the fixing rod 01, the rubber pad 15 can increase the contact force and at the same time avoid scratching the fixing rod 01.
[0039] Reference Figure 1 and Figure 2 The mounting plate 5 is also equipped with an indicator arrow 16, which can be set on the mounting plate 5 by means of engraving, printing, or pasting. The side wall of the slide rail 7 is provided with a scale strip 17 arranged along the length of the box. The scale strip 17 is generally a linear scale mark, set on the side wall of the box by means of laser engraving or printing. The indicator arrow 16 points to the scale strip 17, allowing the operator to accurately know the position of the mounting plate 5 by observing the scale indicated by the indicator arrow 16, facilitating precise adjustment of the mounting plate 5's position.
[0040] Reference Figure 3 and Figure 4 The enclosure includes a junction box 18 and a bottom support 19. The junction box 18 and the bottom support 19 are detachably connected. This design facilitates the handling, installation, and maintenance of the enclosure, and solves the inconvenience of traditional one-piece molding or a large number of bolt connections. Specifically, multiple connecting blocks 20 are provided on both sides of the junction box 18, with two on each side in this embodiment.
[0041] Reference Figure 3 , Figure 4 and Figure 5 The bottom support 19 is provided with snap-fit blocks 21 that correspond one-to-one with multiple connecting blocks 20. The snap-fit blocks 21 are block-shaped structures and are welded to the bottom support 19. The snap-fit blocks 21 have snap-fit grooves 22 for the connecting blocks 20 to be inserted. The size and shape of the snap-fit grooves 22 match the connecting blocks 20, so that the connecting blocks 20 can be tightly inserted into the snap-fit grooves 22.
[0042] Reference Figure 3 , Figure 4 and Figure 5 The snap-fit block 21 has a rotating groove 23 on its side wall, which communicates with the snap-fit groove 22. The rotating groove 23 is a rectangular recess for accommodating the hook plate 24. A sliding rod 25 is laterally slidably mounted on the snap-fit block 21. The sliding rod 25 is generally a cylindrical rod, and its material can be metal. The hook plate 24 is rotatably mounted inside the rotating groove 23. The hook plate 24 has a plate-like structure, with one end bent into a hook shape.
[0043] Reference Figure 3 , Figure 4 and Figure 5 The side wall of the hook plate 24 is provided with a waist-shaped through groove 26. One end of the sliding rod 25 is inserted into the rotating groove 23 and passes through the waist-shaped through groove 26, and also passes through the snap-fit block 21. The connecting block 20 is provided with a hook groove 27. One end of the hook plate 24 is inserted into the hook groove 27 and abuts against the bottom wall of the hook groove 27.
[0044] Reference Figure 3 , Figure 4 and Figure 5 A fixing block 28 is connected to the sliding rod 25. The fixing block 28 is generally a block structure and is fixed to the sliding rod 25 by welding. The fixing block 28 is inserted into the waist-shaped through groove 26 and fits against the side wall of the waist-shaped through groove 26. The function of the fixing block 28 is to limit the rotation range of the hook plate 24 and ensure that the hook plate 24 can be accurately inserted into the hook groove 27. A limiting ring plate 29 is provided at one end of the sliding rod 25, and a pull plate 30 is provided at the other end. The limiting ring plate 29 is threadedly connected to the sliding rod 25. The limiting ring plate 29 can prevent the sliding rod 25 from coming out of the snap-fit block 21, and plays a role in limiting and fixing.
[0045] Reference Figure 3 , Figure 4 and Figure 5 The fixed block 28 is inclined at one end facing the limiting ring plate 29. The inclined surface is inclined in the vertical direction away from the limiting ring plate 29. The fixed block 28 with the inclined surface can be set to enter the waist-shaped through groove 26 more smoothly, which makes it easier for the sliding rod 25 to drive the hook plate 24 to rotate, so that the hook plate 24 can be smoothly inserted into the hook groove 27 of the connecting block 20 to realize the connection between the junction box 18 and the bottom bracket 19, thereby improving the assembly efficiency.
[0046] The implementation principle of this embodiment is as follows: During use, the operator rotates the adjusting rod 2, and the hanging plate 5 is threadedly connected to the adjusting rod 2. Under the guidance of the slider 6 and the slide rail 7, the hanging plate 5 moves up and down, so that the operator can adjust the position of the hanging hole 8 according to the position of the fixed rod 01. After adjustment, the hanging hole 8 is inserted into the fixed rod 01 to achieve installation. Compared with the difficulty in accurately positioning the opening and slotting, this application has high convenience and applicability, making it easy to install the optical cable junction box and realizing flexible adjustment of the position of the hanging plate 5. In addition, the box adopts a detachable design. Through the cooperation of components such as the connecting block 20, the snap-fit block 21, the hook plate 24 and the sliding rod 25, the junction box 18 and the bottom bracket 19 can be quickly connected and disassembled, which greatly improves the operational convenience of the box during transportation, installation and maintenance, and reduces labor intensity and operation time.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
