Description

Technical Field

[0001] This utility model relates to the technical field of optical cable junction boxes, specifically to a liftable wall-mounted optical cable junction box. Background Technology

[0002] Optical cable junction boxes are primarily used as interface devices at the junction of trunk optical cables and distribution optical cables in optical cable access networks. The structure of an optical cable junction box mainly consists of a box body, internal metal components, optical fiber connectors, and spare parts. Depending on the application, they can be divided into indoor and outdoor types, and can be floor-mounted, overhead, or wall-mounted.

[0003] However, for wall-mounted fiber optic junction boxes, their fixed height after initial installation means that personnel must climb to height for subsequent use, making them inconvenient to use overall.

[0004] Based on this, we propose a height-adjustable wall-mounted optical cable junction box. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a height-adjustable wall-mounted optical cable junction box, which solves the technical problem that in the prior art, after the initial installation, the fixed height of the box means that personnel need to climb to a height for subsequent use, making the overall use inconvenient.

[0006] According to one aspect, at least one embodiment of the present invention provides a liftable wall-mounted optical cable junction box, comprising:

[0007] A limiting plate, wherein a positioning seat is fixedly connected to the top and bottom of one side of the limiting plate, and a limiting strip is vertically slidably connected to both ends of the other side of the limiting plate, and a support plate is fixedly connected to the top of the limiting plate;

[0008] The main body of the junction box has mounting plates fixedly connected to both ends of its back. A connecting rod is fixedly connected to the mounting plate, and the end of the connecting rod away from the mounting plate is fixed to a corresponding limiting strip.

[0009] A transmission assembly, which is assembled between a limiting plate and a support plate, is used to adjust the vertical position of the main body of the junction box in conjunction with the positioning seat.

[0010] For example, in at least one embodiment of this utility model, a liftable wall-mounted optical cable junction box is provided, wherein the transmission assembly includes:

[0011] The positioning ear is fixedly connected to the bottom end of the support plate. A transmission plate is rotatably connected to the positioning ear. A transmission slot is opened in the middle of the transmission plate. A push rod is rotatably connected to the end of the transmission plate away from the positioning ear. An assembly base is fixedly connected to the top of the main body of the junction box, and the end of the push rod away from the transmission slot is also rotatably connected to the top of the assembly base.

[0012] A transmission seat is fixedly connected to the top of the other side of the limiting plate. A transmission screw is rotatably connected to the inner side of the transmission seat. A displacement seat is threadedly connected to the transmission screw. A linkage column is fixedly connected to one end of the displacement seat, and the linkage column is also movably connected inside the transmission through groove.

[0013] A stabilizing component is mounted at the bottom of the transmission base to limit the rotation of the transmission screw.

[0014] For example, in at least one embodiment of this utility model, a height-adjustable wall-mounted optical cable junction box includes the following stabilization components:

[0015] A stabilizing cylinder is rotatably connected to the bottom end of a transmission base, and the bottom end of a transmission screw is also fixedly connected to the stabilizing cylinder. A stabilizing shaft is vertically slidably connected to the bottom end of the stabilizing cylinder, and a displacement plate is fixedly connected to one end of the stabilizing shaft located inside the stabilizing cylinder.

[0016] Two limiting grooves are respectively opened on both sides of the stabilizing cylinder, and a stabilizing block is vertically slidably connected inside the limiting groove. One end of the stabilizing block inside the stabilizing cylinder is also fixedly connected to a displacement plate. A helical spring is fixedly connected between the bottom end of the displacement plate and the stabilizing cylinder.

[0017] For example, in at least one embodiment of the present invention, a wall-mounted optical cable junction box that can be raised and lowered is provided, which further includes: both ends of the other side of the limiting plate are provided with straight sliding grooves, and the two limiting strips are respectively slidably connected inside the two straight sliding grooves.

[0018] For example, in at least one embodiment of the present invention, a wall-mounted optical cable junction box that can be raised and lowered further includes: a mounting rod fixedly connected to the top of the mounting base, and the end of the push rod away from the transmission plate is rotatably connected to the outside of the mounting rod.

[0019] For example, in at least one embodiment of the present invention, a wall-mounted optical cable junction box that can be raised and lowered is provided, which further includes: a linear guide rod that is vertically fixedly connected inside the transmission seat, and a stabilizing hole is provided at one end of the displacement seat near the linear guide rod, and the stabilizing hole and the linear guide rod are in clearance fit.

[0020] For example, in at least one embodiment of the present invention, a wall-mounted optical cable junction box that can be raised and lowered is provided, which further includes: anti-slip pads are fixedly connected to the bottom end of the transmission seat and the top end of the stabilizing block, and the anti-slip pads are provided with anti-slip patterns.

[0021] For example, in at least one embodiment of the present invention, a wall-mounted optical cable junction box that can be raised and lowered is provided, which further includes: a hanging ring fixedly connected to one end of the stabilization shaft located outside the stabilization cylinder.

[0022] The beneficial effects of the embodiments of this utility model are as follows:

[0023] In this invention, the vertical height of the junction box can be stably adjusted after the main body of the junction box is assembled, through the structural cooperation of the limiting strip and the transmission component, so that personnel do not need to climb to heights to work, making the whole process more convenient.

[0024] In this invention, through the structural cooperation of the stabilizing components, the transmission screw can be stopped and limited in a non-rotating state, thus ensuring the stability of the transmission screw application. Attached Figure Description

[0037] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] like Figures 1-4 As shown, it illustrates a liftable wall-mounted optical cable junction box according to one embodiment of the present invention.

[0039] In some examples, including:

[0040] The limiting plate 1 has a positioning seat 2 fixedly connected to the top and bottom of one side of the limiting plate 1, and a limiting strip 3 vertically slidably connected to both ends of the other side of the limiting plate 1. The top of the limiting plate 1 is fixedly connected to a support plate 4.

[0041] The main body of the junction box 5 has mounting plates 6 fixedly connected to both ends of its back. A connecting rod 7 is fixedly connected to the mounting plate 6, and the end of the connecting rod 7 away from the mounting plate 6 is fixed to the corresponding limiting strip 3.

[0042] The transmission assembly 8 is assembled between the limiting plate 1 and the support plate 4, and is used to adjust the vertical position of the main body 5 of the transfer box in conjunction with the positioning seat 2.

[0043] The main body 5 of the junction box includes:

[0044] Enclosure: The enclosure is made of stainless steel to withstand drastic climate changes and harsh working environments. It features a door and ample internal space for fabric and fiber storage, facilitating user operation.

[0045] Integrated fusion splice tray: Used for splicing and terminating optical cables, ensuring stable connections.

[0046] Fiber optic cable fixing plates and fiber optic hanging posts: used to fix and hang fiber optic cables, ensuring their stability and safety;

[0047] Internal metal fittings and fiber optic connectors: These include various metal fittings and fiber optic connectors for splicing and patching optical cables to enable optical signal transmission;

[0048] These are mature existing technologies, and will not be elaborated upon here;

[0049] For example, such as Figure 2As shown, straight grooves 24 are provided at both ends of the other side of the limiting plate 1, and the two limiting strips 3 are slidably connected inside the two straight grooves 24 respectively. The straight grooves 24 effectively guide the vertical displacement of the limiting strips 3, preventing uncontrollable displacement. In this embodiment, the straight grooves 24 can be T-shaped.

[0050] For example, such as Figures 3-4 As shown, the transmission assembly 8 includes:

[0051] Positioning ear 9 is fixedly connected to the bottom end of support plate 4. A transmission plate 10 is rotatably connected to the positioning ear 9. A transmission groove 11 is opened in the middle of the transmission plate 10. A push rod 12 is rotatably connected to the end of the transmission plate 10 away from the positioning ear 9. An assembly base 13 is fixedly connected to the top end of the junction box body 5. The end of the push rod 12 away from the transmission groove 11 is also rotatably connected to the top end of the assembly base 13.

[0052] The transmission seat 14 is fixedly connected to the top of the other side of the limiting plate 1. The transmission screw 15 is rotatably connected to the inner side of the transmission seat 14. The displacement seat 16 is threadedly connected to the transmission screw 15. One end of the displacement seat 16 is fixedly connected to the linkage column 17, and the linkage column 17 is also movably connected to the inside of the transmission through groove 11.

[0053] For example, such as Figure 3 As shown, a mounting rod 25 is fixedly connected to the top of the mounting base 13, and the end of the push rod 12 away from the transmission plate 10 is rotatably connected to the outside of the mounting rod 25. Through the setting of the mounting rod 25, the push rod 12 can be effectively assembled, ensuring the smooth connection of the push rod 12 between the mounting base 13 and the transmission plate 10.

[0054] For example, such as Figure 3 As shown, a linear guide rod 26 is vertically fixedly connected inside the transmission seat 14, and a stabilizing hole is provided at one end of the displacement seat 16 near the linear guide rod 26. The stabilizing hole and the linear guide rod 26 are in clearance fit. By setting the linear guide rod 26, the displacement seat 16 can be rotated and limited to prevent the displacement seat 16 from rotating with the transmission screw 15, thus ensuring the stability of the displacement seat 16 during displacement.

[0055] For example, such as Figure 4 As shown, anti-slip pads are fixedly connected to the bottom of the transmission seat 14 and the top of the stabilizing block 22. The anti-slip pads have anti-slip patterns. By setting the anti-slip pads, the friction between the stabilizing block 22 and the transmission seat 14 can be increased, thus preventing the transmission screw 15 from rotating uncontrollably.

[0056] A stabilizing component is mounted at the bottom of the transmission base 14 to limit the rotation of the transmission screw 15.

[0057] like Figures 4-5 As shown, it illustrates a stabilization component in another embodiment of the present invention.

[0058] In some examples, such as Figure 4 As shown, the stabilization components include:

[0059] Stabilizing cylinder 18 is rotatably connected to the bottom end of transmission seat 14, and the bottom end of transmission screw 15 is also fixedly connected to stabilizing cylinder 18. Stabilizing shaft 19 is vertically slidably connected to the bottom end of stabilizing cylinder 18, and a displacement plate 20 is fixedly connected to one end of stabilizing shaft 19 located inside stabilizing cylinder 18.

[0060] Two limiting grooves 21 are respectively opened on both sides of the stabilizing cylinder 18, and a stabilizing block 22 is vertically slidably connected inside the limiting groove 21. One end of the stabilizing block 22 inside the stabilizing cylinder 18 is also fixedly connected to the displacement plate 20. A helical spring 23 is fixedly connected between the bottom end of the displacement plate 20 and the stabilizing cylinder 18.

[0061] For example, such as Figure 4 As shown, a hanging ring 27 is fixedly connected to one end of the stabilizing shaft 19 located outside the stabilizing cylinder 18. The hanging ring 27 is used to... Figure 5 The top of the tool is attached to the hanging ring 27. Pulling the hanging ring 27 downwards will cause the stabilizing block 22 to move away from the transmission seat 14 with the help of the displacement plate 20, thereby reducing the friction of the transmission screw 15. Then it will rotate. Figure 5 The tool shown can drive the transmission screw 15 to rotate. Because the displacement plate 20 can compress the helical spring 23 when it is displaced, when... Figure 5 After the tool shown is separated from the hanging ring 27, it can push the stabilizing block 22 to make close contact with the transmission seat 14 with the help of the helical spring 23, so as to prevent the transmission screw 15 from rotating uncontrollably.

[0062] Working principle: First, the limiting plate 1 is fixed to the wall at a suitable height using the positioning seat 2 and external connectors. The wiring harness entering the junction box body 5 must have sufficient length for the junction box body 5 to descend. When using the limiting plate 1 subsequently, it is first secured to the wall using the positioning seat 2 and external connectors. Figure 5 The tool shown pulls the hanging ring 27 downwards, causing the hanging ring 27 to move the stabilizing block 22 away from the transmission seat 14 by means of the stabilizing shaft 19 and the displacement plate 20, thereby unlocking the transmission screw 15, and then by means of Figure 5The tool shown rotates the stabilizing cylinder 18. With the connection between the stabilizing cylinder 18 and the transmission screw 15, the transmission screw 15 drives the displacement seat 16 to move vertically. Since the linkage column 17 is connected inside the transmission channel 11, when the displacement seat 16 moves linearly, it can press the transmission plate 10 with the help of the linkage column 17, causing the transmission plate 10 to rotate under the support of the positioning ear 9. Since the push rod 12 is connected between the transmission plate 10 and the assembly seat 13, when the transmission plate 10 rotates, it can push the assembly seat 13 through the push rod 12, causing the transfer box body 5 to be vertically adjusted under the limit of the limit strip 3, so as to lower the transfer box body 5 to a height that is convenient for personnel to operate and avoid personnel working at height.

Although this utility model 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
