Description

Technical Field

[0001] This application relates to the field of fiber optic distribution cabinets, and more particularly to a fiber optic distribution drawer. Background Technology

[0002] In the field of communications, optical fiber is an essential carrier for forming optical communication transmission network channels, and optical distribution frame (ODF) is an essential device for optical fiber communication network terminals and relay sites to realize fiber routing, patching and access functions.

[0003] In power system optical communication networks, tasks such as equipment aging and renovation, large-scale technical upgrades, scheduled maintenance, and handling of sudden faults often involve repeatedly opening the fiber optic distribution cabinet drawers for fiber optic patching and other work. Traditional fiber optic distribution drawers have limited opening capabilities; generally, only the cover rotatably connected to the main body of the drawer can be opened to maintain the optical fibers installed in the drawer, thus reducing the efficiency of fiber optic distribution drawer maintenance. Summary of the Invention

[0004] To improve the efficiency of inspection and maintenance of fiber optic distribution drawers, this application provides a fiber optic distribution drawer.

[0005] The fiber optic distribution drawer provided in this application adopts the following technical solution:

[0006] A fiber optic distribution drawer includes a fixed body and a rotating body, the fixed body and the rotating body being rotatably connected. The fixed body is fixedly connected to the cabinet of the fiber optic distribution cabinet, so that the rotating body can rotate out from inside the cabinet of the fiber optic distribution cabinet.

[0007] The rotating body includes a mounting part and at least two cover parts. The mounting part has a mounting cavity. Each of the cover parts is rotatably connected to each other, and at least two of the cover parts are respectively disposed on two mutually perpendicular sides of the mounting part. One cover part is rotatably connected to the mounting part, and another cover part is connected to the mounting part, so that each of the cover parts can open or close the mounting cavity.

[0008] By adopting the above technical solution, when the optical communication network in the power system needs to perform aging retrofits, major technical upgrades, scheduled maintenance, and handling of sudden faults, the rotating body and the fixed body rotate relative to each other, causing the rotating body to rotate out of the fiber optic distribution cabinet. Subsequently, each cover rotates away from the mounting section, thus opening the mounting cavity. When a low degree of opening of the mounting cavity is required, only the covers located on one side of the mounting section rotate away from the mounting section, achieving a low degree of opening. When a larger opening of the mounting cavity is needed... When the mounting section is in operation, each cover portion located on each side of the mounting section rotates away from the mounting section, thereby opening at least one mutually perpendicular side of the mounting section. This results in a greater degree of opening of the mounting cavity, improving the efficiency of inspection and maintenance of the fiber optic distribution drawer. This addresses the problem of traditional fiber optic distribution drawers having a low degree of opening, typically only allowing the cover rotatably connected to the main body of the drawer to be opened for maintenance of the optical fiber installed in the drawer, thus reducing the efficiency of inspection and maintenance.

[0009] Optionally, one of the cover portions is fixedly provided with at least one connecting protrusion, and the mounting portion is provided with at least one connecting groove. When each of the cover portions closes the mounting cavity, each of the connecting protrusions passes through each of the connecting grooves.

[0010] Optionally, the connecting protrusion includes a through portion and a limiting portion, the through portion and the limiting portion being fixedly connected, and the through portion passing through the connecting groove.

[0011] Optionally, the mounting section is provided with multiple mounting brackets, each of which is used to mount communication equipment.

[0012] Optionally, each of the mounting brackets includes a first frame portion and a second frame portion, the first frame portion and the second frame portion are fixedly connected, the first frame portion is located inside the mounting cavity, and the second frame portion is located outside the mounting cavity.

[0013] Optionally, the mounting part has multiple through-hole frame slots, and the second frame part is fixedly provided with at least one frame protrusion. The frame protrusion is U-shaped. When the mounting frame is installed on the mounting part, the frame protrusion passes through the frame slot and abuts against the slot.

[0014] Optionally, the rotating body further includes a base plate, one end of which is rotatably connected to the mounting portion, and the other end of which is detachably connected to the mounting portion. The base plate is used to protect each of the mounting brackets.

[0015] Optionally, a magnetic suction component is fixedly provided on the mounting part or the base plate part, and when the other end of the base plate part is detachably connected to the mounting part, the magnetic suction component is magnetically fixed to the base plate part or the mounting part.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] When the optical communication network in the power system requires aging retrofitting, major technical upgrades, scheduled maintenance, and handling of sudden faults, the rotating body and the fixed body rotate relative to each other, causing the rotating body to rotate out of the fiber optic distribution cabinet. Then, each cover rotates away from the mounting part, opening the mounting cavity. When a low degree of opening is required, only the covers on one side of the mounting part rotate away from it, achieving a small opening. When a larger opening is needed, all covers on each side of the mounting part rotate away from it, opening at least one perpendicular side of the mounting part, resulting in a greater opening degree. This improves the efficiency of fiber optic distribution drawer maintenance and addresses the problem of traditional fiber optic distribution drawers having a low opening degree, typically only allowing opening of the cover rotatably connected to the main body of the drawer to maintain the optical fiber, thus reducing the efficiency of fiber optic distribution drawer maintenance.

[0028] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0029] This application discloses an optical fiber distribution drawer. (Refer to...) Figure 1 and Figure 2 A fiber optic distribution drawer includes a fixed body 1 and a rotating body 2. The fixed body 1 and the rotating body 2 are rotatably connected. The specific connection method between the fixed body 1 and the rotating body 2 is not limited. For example, the fixed body 1 and the rotating body can be rotatably connected by studs or shafts. The fixed body 1 can be fixedly connected to the cabinet of the fiber optic distribution cabinet so that the rotating body 2 can rotate out from the inside of the cabinet, thereby facilitating the installation and wiring of communication equipment. Both the fixed body 1 and the rotating body 2 have at least one through-hole cable tray 11 and multiple cable management trays 12 for organizing cable bundles, thereby facilitating the installation of communication equipment.

[0030] Reference Figure 3 and Figure 4 The rotating body 2 includes a mounting part 21 and two cover parts 22. The mounting part 21 has a mounting cavity 210. The cover parts 22 are rotatably connected to each other, and the two cover parts 22 are respectively disposed on two mutually perpendicular sides of the mounting part 21. One cover part 22 is rotatably connected to the mounting part 21, and the other cover part 22 is connected to the mounting part 21, so that each cover part 22 can open or close the mounting cavity 210.

[0031] Reference Figure 5The mounting section 21 includes a base plate side 211, two wiring sides 212, and a mounting side 213. The base plate side 211 is fixedly provided with a plurality of mounting rings 2111 for mounting communication equipment. The two wiring sides 212 are respectively fixedly provided at both ends of the base plate side 211 and are symmetrically distributed along the center plane of the base plate side 211. Each wiring groove 11 is located on the two wiring sides 212. The mounting side 213 is fixedly provided at one end of the bottom of the base plate side 211. The mounting side 213 has a plurality of through mounting grooves 2131, each of which is used to install communication equipment. The base plate side 211, the two wiring sides 212, and the mounting side 213 are interconnected to form a mounting cavity 210 for mounting communication equipment. A cover part 22 is provided opposite to the base plate side 211 and the mounting side 213.

[0032] Reference Figure 6 A plurality of connecting protrusions 221 are fixedly provided on the cover portion 22 located opposite the bottom plate side 211. Each connecting protrusion 221 is located at the end of the cover portion 22 near the mounting side 213. The mounting side 213 has a plurality of connecting grooves 2132. When each cover portion 22 closes the mounting cavity 210, each connecting protrusion 221 passes through the corresponding connecting groove 2132. The connecting protrusion 221 includes a passing portion 2211 and a limiting portion 2212. The positioning part 2212 is fixedly connected, the through part 2211 can pass through the connecting groove 2132, and the limiting part 2212 is not easy to pass through the connecting groove 2132. As a result, when the connecting protrusion 221 moves in the direction perpendicular to the mounting side 213 toward the cover part 22, the limiting part 2212 is not easy to pass through the connecting groove 2132. As a result, when each connecting protrusion 221 passes through each connecting groove 2132, each cover part 22 can be stably connected to the mounting part 21.

[0033] Reference Figure 7 and Figure 8 The mounting side 213 is provided with multiple mounting brackets 2133, each of which is used to install communication equipment. Each mounting bracket 2133 includes a first bracket part 21331 and a second bracket part 21332. The first bracket part 21331 and the second bracket part 21332 are fixedly connected. The first bracket part 21331 is located inside the mounting cavity 210, and the second bracket part 21332 is located outside the mounting cavity 210. The mounting side 213 has multiple through-hole bracket slots 2134. The second bracket part 21332 is fixedly provided with multiple bracket protrusions 213321. The bracket protrusions 213321 are U-shaped. When the mounting bracket 2133 is installed on the mounting part 21, each bracket protrusion 213321 passes through each bracket slot 2134, and each bracket protrusion 213321 abuts against the slot of each bracket slot 2134.

[0034] Reference Figure 9The rotating body 2 also includes a base plate 23. One end of the base plate 23 is rotatably connected to the mounting part 21, and the other end of the base plate 23 is detachably connected to the mounting part 21. The base plate 23 is used to protect each mounting bracket 2133. A magnetic suction member 2112 is fixedly provided on the side 211 of the base plate. When the other end of the base plate 23 is detachably connected to the mounting part 21, the magnetic suction member 2112 is magnetically fixed to the base plate 23.

[0035] The implementation principle of a fiber optic distribution cabinet according to an embodiment of this application is as follows: When the optical communication network in the power system needs to perform aging retrofits, major technical upgrades, scheduled maintenance, and handling of sudden faults, the rotating body 2 and the fixed body 1 rotate relative to each other, causing the rotating body 2 to rotate out of the cabinet of the fiber optic distribution cabinet. Subsequently, each cover part 22 rotates away from the mounting part 21, thereby opening the mounting cavity 210. When the required degree of opening of the mounting cavity 210 is low, only each cover part 22 located on one side of the mounting part 21 rotates away from the mounting part 21, which can achieve a low degree of opening of the mounting cavity 210. When expansion is required... When the large mounting cavity 210 is opened to its maximum extent, each cover portion 22 located on each side of the mounting portion 21 rotates away from the mounting portion 21, thereby opening at least one mutually perpendicular side of the mounting portion 21. This results in a larger opening extent for the mounting cavity 210, which in turn improves the efficiency of inspection and maintenance of the fiber optic distribution drawer. This addresses the problem of traditional fiber optic distribution drawers having a low opening extent, typically only allowing the cover rotatably connected to the main body of the fiber optic distribution drawer to be opened for maintenance of the optical fiber installed in the main body of the fiber optic distribution drawer, thus reducing the efficiency of inspection and maintenance of the fiber optic distribution drawer.

[0036] 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.
