Technical Field
[0001] This utility model belongs to the field of fiber optic terminal box technology, and particularly relates to a desktop fiber optic terminal box. Background Technology
[0002] A fiber optic terminal box is the termination point of a fiber optic cable. One end is the fiber optic cable, and the other end is a pigtail. Essentially, it's a device that splits a fiber optic cable into individual optical fibers. A wall-mounted user fiber optic terminal box provides fiber-to-fiber splicing, fiber-to-pigtail splicing, and optical connector connection; it also provides mechanical and environmental protection for the optical fibers and their components, and allows for appropriate inspection to maintain the highest standards of fiber optic management.
[0003] Existing desktop fiber optic terminal boxes are typically placed directly on an office desk. When cleaning up clutter, the terminal box may be accidentally bumped, causing it to shift position. This can lead to physical damage such as squeezing or breaking of the fiber optic connectors or fibers inside the box. In severe cases, the entire terminal box may need to be replaced, increasing maintenance costs. Utility Model Content
[0004] This utility model addresses the problem that in existing desktop fiber optic terminal boxes, the terminal box is typically placed directly on a desk. When clearing away clutter, the terminal box is easily bumped, causing it to shift position and potentially leading to physical damage such as compression or breakage of the internal fiber optic connectors or fibers. In severe cases, this may necessitate replacing the entire terminal box. The following technical solution is proposed:
[0005] A desktop fiber optic terminal box includes: a terminal box body, a top cover at the top of the terminal box body, a coupler port inside the terminal box body, a suction cup fixedly installed at the bottom of the terminal box body, a connecting pipe fixedly installed at the bottom of the inner wall of the terminal box body, a ring block inside the connecting pipe, a sealing ring fixedly sleeved on the outer side of the ring block, an operating rod fixedly connected to the top of the ring block, and fixed seats symmetrically fixedly installed at the bottom of the inner wall of the terminal box body located outside the connecting pipe. A movable shaft is rotatably connected between the two fixed seats, and a screw is integrally formed on the outer surface of the movable shaft. A stop block is threadedly connected to the outer surface of the screw.
[0006] As a preferred embodiment of the above technical solution, the connecting tube penetrates the terminal box and the bottom end of the connecting tube is fixedly connected to the top end of the suction cup.
[0007] As a preferred embodiment of the above technical solution, the outermost part of the sealing ring is attached to the inner wall of the connecting pipe.
[0008] As a preferred embodiment of the above technical solution, the operating lever is symmetrically fitted with fixing blocks, and both fixing blocks are slidably sleeved on the outside of the screw.
[0009] As a preferred embodiment of the above technical solution, a slide rail is fixedly installed at the bottom of the inner wall of the terminal box, a welding tray is provided at the top of the slide rail, and a slide bar is fixedly installed at the bottom of the welding tray.
[0010] As a preferred embodiment of the above technical solution, a fixed groove block is fixedly installed at one end of the slide bar, and a movable rod is rotatably connected to one end of the slide rail.
[0011] The beneficial effects of this utility model are as follows:
[0012] (1) This utility model forms a negative pressure area inside the connecting tube by attaching the suction cup to the table and pulling the operating rod upward. The table blocks the outlet of this area. With the help of atmospheric pressure, the suction cup is firmly attached to the table, thus fixing the optical terminal box to the table. When cleaning items on the table, even if the optical terminal box is touched, it will not move, thus ensuring the stability of the connection between optical fibers inside the optical terminal box, reducing the possibility of the splice point of the pipeline inside the terminal box breaking, and reducing maintenance costs.
[0013] (2) By sliding the splice plate inside the terminal box, this utility model facilitates the disassembly and installation of the splice plate. When the terminal box malfunctions, it facilitates quick inspection and repair of the fiber optic splice or splice plate, thereby improving the efficiency of equipment maintenance.

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0024] Example 1
[0025] This utility model provides a desktop fiber optic terminal box, such as Figures 1 to 8 As shown, the device includes a terminal housing 1, a top cover 2 at the top of the terminal housing 1, the top cover 2 being detachably mounted on the top of the terminal housing 1 by screws and other components, a coupler port 3 inside the terminal housing 1, a suction cup 4 fixedly mounted at the bottom of the terminal housing 1, a connecting pipe 5 fixedly mounted at the bottom of the inner wall of the terminal housing 1, a ring block 6 inside the connecting pipe 5, a sealing ring 7 made of rubber fixedly fitted to the outer side of the ring block 6, and an operating lever 8 fixedly connected to the top of the ring block 6. The operating lever 8 consists of a vertical rod and a notched disc, with the vertical rod fixedly mounted at the center of the disc. The bottom of the inner wall of the terminal housing 1 is located at the connecting pipe 5. A fixed base 9 is symmetrically fixedly installed on the outer side of the tube 5. A movable shaft 10 is rotatably connected between the two fixed bases 9. A screw 11 is integrally formed on the outer surface of the movable shaft 10. A stop block 12 is threadedly connected to the outer surface of the screw 11. By rotating the screw 11 to make it vertical, and then rotating the stop block 12, it moves upward along the outer side of the screw 11, thereby moving the stop block 12 to the bottom end of the disc of the operating rod 8. This causes the opposite surfaces of the stop block 12 and the disc of the operating rod 8 to fit together, thereby fixing the operating rod 8 at the top of the stop block 12. This prevents the operating rod 8 from automatically returning to its original position due to atmospheric pressure after being stretched.
[0026] like Figures 2 to 6As shown, the connecting tube 5 passes through the terminal box 1 and its bottom end is fixedly connected to the top end of the suction cup 4. The bottom end of the suction cup 4 is attached to the office desktop, and the outermost edge of the sealing ring 7 is attached to the inner wall of the connecting tube 5. This ensures that the outermost edge of the sealing ring 7 remains attached to the inner wall of the connecting tube 5 as it moves inside the connecting tube 5, effectively preventing air from flowing out of the connecting tube 5. This creates a negative pressure area between the sealing ring 7 and the suction cup 4. The bottom end of the suction cup 4 is attached to the desktop, blocking the outlet of the negative pressure area. Under atmospheric pressure, the suction cup 4 is fixed to the desktop.
[0027] like Figure 5 and Figure 6 As shown, two fixing blocks 13 are symmetrically engaged inside the operating rod 8. Both fixing blocks 13 are slidably sleeved on the outside of the screw 11. The inner diameter of the fixing blocks 13 is the same as the outer diameter of the screw 11. By passing the fixing blocks 13 through the screw 11 and engaging them inside the operating rod 8, the outer side of the screw 11 is made to fit against the inner wall of the fixing blocks 13, thereby fixing the screw 11 in the vertical direction, preventing the screw 11 from rotating, and ensuring the stability of the device during operation.
[0028] like Figure 7 and Figure 8 As shown, a slide rail 14 is fixedly installed at the bottom of the inner wall of the terminal box 1. A welding tray 15 is provided at the top of the slide rail 14. A slide bar 16 is fixedly installed at the bottom of the welding tray 15. A fixing groove block 17 is fixedly installed at one end of the slide bar 16. A movable rod 18 is rotatably connected to one end of the slide rail 14. A groove is formed between the fixing groove block 17 and the opposite surface of the slide rail 14. The width of the movable rod 18 is the same as the width of the groove. By fully engaging the slide bar 16 into the slide rail 14, the welding tray 15 is installed at the top of the slide rail 14. Then, the movable rod 18 is rotated to engage with the groove position opened in the fixing groove block 17, thereby completely fixing the slide bar 16 into the slide rail 14. The welding tray 15 is then fixedly installed at the top of the slide rail 14. The operation is simple and facilitates the disassembly and maintenance of the welding tray 15.
[0029] Working principle: When using this device, place the terminal box 1 on the office desktop, so that the bottom end of the suction cup 4 is attached to the desktop. Pull the operating rod 8 to move the sealing ring 7 away from the desktop, so that the air between the sealing ring 7 and the suction cup 4 forms a negative pressure area. The suction cup 4 is attached to the desktop, so that the desktop blocks the gap of this negative pressure area. Under the action of atmospheric pressure, the suction cup 4 is firmly attached to the desktop. Then rotate the stop block 12 to move it upward along the outside of the screw 11, so that the opposite surfaces between the stop block 12 and the disc of the operating rod 8 are attached to each other. Then, the fixing block 13 passes through the screw 11 and is locked into the inside of the operating rod 8, so that the screw 11 is fixed in the vertical position, so that the stop block 12 is attached to the operating rod 8, preventing the operating rod 8 from moving downward, ensuring the stability of the device during operation. Thus, the terminal box 1 is fixedly installed on the desktop, so that when cleaning objects on the desktop, touching the terminal box 1 will not cause it to move, thus ensuring the stability of the fiber optic connection inside the terminal box 1 and effectively reducing the possibility of the fiber optic splice breaking.
[0030] Next, fully engage the slide bar 16 inside the slide rail 14, rotate the movable rod 18 to engage it in the groove position formed by the fixed slot block 17 and the slide rail 14, and then fix the slide bar 16 inside the slide rail 14. Then fix the welding tray 15 inside the terminal box 1. This is easy to disassemble and simple to operate. When the terminal box 1 malfunctions, it is easy to quickly disassemble, inspect and repair the welding tray 15, thus improving the efficiency of equipment maintenance.
[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
