Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, specifically a pull-out fiber optic distribution frame. Background Technology

[0002] A fiber optic distribution frame is a device used in fiber optic communication systems for terminating and distributing backbone optical cables at the central office level. It facilitates the connection, distribution, and scheduling of fiber optic lines. Its core principle is to provide a standardized platform for installing and protecting fiber optic connectors.

[0003] A search revealed a utility model patent with Chinese patent publication number CN220040835U, which discloses a pull-out fiber optic patch panel, including a placement box. A pull frame is slidably inserted into the placement box, and two rows of plug-in terminals are fixed at equal intervals on the inner surface of the pull frame. Wire holes are opened on both sides of the outer end of the pull frame, and fiber optic cables are inserted into the plug-in terminals.

[0004] The aforementioned device separates and fixes optical fibers by setting limiting components. In actual operation, it needs to be operated one by one. When there are many optical fibers, it will consume a lot of time, and the disassembly and assembly operations are inconvenient, which is not conducive to improving work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a pull-out fiber optic patch panel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pull-out fiber optic distribution frame, comprising a placement box, a pull frame slidably inserted inside the placement box, a splitter assembly installed inside the pull frame, the splitter assembly comprising a splitter frame fixedly connected to the bottom inner wall of the pull frame, a plurality of equally spaced slots opened on the top inner wall of the splitter frame, a baffle hinged to one side of the top outer wall of the splitter frame, an extension plate fixedly connected to one side of the outer wall at both ends of the baffle, a limiting pin slidably inserted inside each of the two extension plates, the two limiting pins slidably inserted inside the splitter frame, and a spring sleeved on the outside of each of the two limiting pins, the two ends of the spring being fixedly connected to the limiting pin and the extension plate respectively.

[0007] As a further preferred embodiment of this technical solution, an inclined surface is provided on one side of the outer wall at both ends of the splitter frame, and a horizontally arranged extension column is fixedly connected to one side of the outer wall of each of the two limiting pins. The two extension columns are fitted with the same guide frame, and the guide frame has a figure-eight shaped guide groove inside, with the two guide grooves respectively fitted on the outside of the two extension columns.

[0008] It can quickly separate optical fibers and ensure that the position of the optical fibers does not change arbitrarily. There is no need to fix each optical fiber separately. The operation is convenient enough. Place the optical fibers into several slots, then flip the baffle to bring it close to the splitter frame. The spring's insertion end first contacts the inclined surface. As the baffle moves down, the limiting pin is guided by the inclined surface to move outward and then contacts the outer wall of the splitter frame. When the baffle and the splitter frame are in contact, the spring will drive the limiting pin to insert into the corresponding card hole, and the position of the baffle will be firmly restricted.

[0009] As a further preferred embodiment of this technical solution, a limiting component is installed inside the splitter frame. The limiting component includes a limiting groove opened at the bottom of the outer wall of one end of the splitter frame. A movable frame is slidably inserted into the limiting groove. Several limiting wheels are rotatably connected to the top inner wall of the movable frame through bearings, and a limiting wheel is rotatably connected to the bottom inner wall of several partitions through bearings. A bolt is threadedly connected to the outer wall of one end of the movable frame, and the bolt fits against the inner wall of the limiting groove.

[0010] Push the movable frame to one side, and it will slide along the limiting groove to one side. This will cause the limiting wheel to move closer to another limiting wheel, clamping the optical fiber between them. Under the action of the limiting wheel, the position of the optical fiber is restricted while also allowing for adjustment. Finally, by rotating the knob to drive the bolt, the movable frame will be driven to press against the inner wall of the limiting groove. Under the action of static friction, the positions of the movable frame and the limiting wheel are fixed.

[0011] As a further preferred embodiment of this technical solution, the inner wall of one end of the pull frame is provided with a number of equally spaced wiring terminals, and the number of wiring terminals are at the same level. Two wire-passing holes are opened on both outer walls of the pull frame.

[0012] As a further preferred embodiment of this technical solution, the same positioning component is installed between the placement box and the pull frame, and the positioning component is located on one side of the placement box.

[0013] As a further preferred embodiment of this technical solution, the positioning component includes two positioning rods that are slidably inserted into one side of the top outer wall of the placement box. The top outer walls of the two positioning rods are fixedly connected to the same connecting rod. Two slots are opened on one side of the top outer wall of the pull frame. Both slots are arranged in a right-angled triangle. The corners of the two positioning rods near the inclined surfaces of the slots are set as arc angles.

[0014] When the pull frame is pulled outward, the positioning rod first contacts the top wall of the pull frame and cannot move. When the pull frame is about to be pulled out, the positioning rod will also enter the slot. Under the action of gravity, the positioning rod slides down the slope of the slot. Then the inner wall of the slot contacts the outer wall of the positioning rod, and the position of the pull frame is restricted and cannot continue to move, preventing the pull frame from directly leaving the inner cavity of the placement box. When the pull frame enters the placement box again, the slot can lift the positioning rod up and move it upward, without affecting the normal movement of the pull frame.

[0015] As a further preferred embodiment of this technical solution, the baffle and the guide frame are fixedly connected by the same multi-stage telescopic rod, and the multi-stage telescopic rod is arranged vertically.

[0016] This utility model provides a pull-out fiber optic distribution frame, which has the following advantages:

[0017] (1) This utility model can quickly separate optical fibers by setting a splitter assembly and a limiting assembly, and ensure that the position of the optical fibers will not change arbitrarily. There is no need to fix each optical fiber separately. The operation is convenient enough. Place the optical fibers in several slots, then flip the baffle to bring it close to the splitter frame. The spring insertion end first contacts the inclined surface. As the baffle moves down, the limiting pin is guided by the inclined surface to move outward and then contacts the outer wall of the splitter frame. When the baffle and the splitter frame are in contact, the spring will drive the limiting pin to be inserted into the corresponding card hole. The position of the baffle will be firmly restricted. Push the moving frame to one side. The moving frame slides to one side along the limiting slide groove. Then the limiting wheel will also be driven to approach another limiting wheel. The optical fiber between the two will be clamped. Under the action of the limiting wheel, the position of the optical fiber is restricted and can also be adjusted. Finally, the bolt is rotated by the knob. The moving frame can be driven to press the inner wall of the limiting slide groove. Under the action of static friction, the position of the moving frame and the limiting wheel is fixed.

[0018] (2) By setting a positioning component, when the pull frame is pulled outward, the positioning rod first contacts the top wall of the pull frame and cannot move. When the pull frame is about to be pulled out, the positioning rod will also enter the slot. Under the action of gravity, the positioning rod slides down along the slope of the slot. Then the inner wall of the slot contacts the outer wall of the positioning rod, and the position of the pull frame is restricted and cannot continue to move, preventing the pull frame from directly leaving the inner cavity of the placement box. When the pull frame enters the placement box again, the slot can lift the positioning rod up and move it upward, without affecting the normal movement of the pull frame. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a pull-out fiber optic patch panel includes a placement box 1. A pull frame 2 is slidably inserted inside the placement box 1. A splitter assembly 5 is installed inside the pull frame 2. The splitter assembly 5 includes a splitter frame 501 fixedly connected to the bottom inner wall of the pull frame 2. Several equally spaced slots 502 are opened on the top inner wall of the splitter frame 501. A baffle 503 is hinged to one side of the top outer wall of the splitter frame 501. An extension plate 504 is fixedly connected to one side of the outer wall at both ends of the baffle 503. A limiting pin 505 is slidably inserted inside each of the two extension plates 504. The two limiting pins 505 are slidably inserted inside the splitter frame 501. A spring 506 is sleeved on the outside of each of the two limiting pins 505. The two ends of the spring 506 are fixedly connected to the limiting pin 505 and the extension plate 504, respectively.

[0026] The splitter 501 has an inclined surface 510 on one side of the outer wall at both ends. The two limit pins 505 are fixedly connected to a horizontally arranged extension column 509 on one side of the outer wall of the circumference. The two extension columns 509 are fitted with the same guide frame 508. The guide frame 508 has a V-shaped guide groove inside, and the two guide grooves are respectively fitted on the outside of the two extension columns 509.

[0027] like Figure 3 As shown, the baffle 503 and the guide frame 508 are fixedly connected by the same multi-stage telescopic rod 507, and the multi-stage telescopic rod 507 is set vertically. The multi-stage telescopic rod 507 can restrict the position of the guide frame 508 without affecting the normal movement of the guide frame 508.

[0028] The optical fibers are placed in several slots 502. Then, the baffle 503 is flipped to bring it closer to the splitter frame 501. The insertion end of the spring 506 first contacts the inclined surface 510. As the baffle 503 moves down, the limiting pin 505 is guided outward by the inclined surface 510 and then contacts the outer wall of the splitter frame 501. When the baffle 503 and the splitter frame 501 are in contact, the spring 506 will drive the limiting pin 505 to insert into the corresponding slot, and the position of the baffle 503 will be firmly restricted. To open the baffle 503, grasp the guide frame 508 and lift it upward. Since the position of the baffle 503 is relatively fixed, the guide frame 508 drives the limiting pin 505 away from the splitter frame 501 through the extension column 509 until the limiting pin 505 disengages from the slot of the splitter frame 501. Then the baffle 503 can be flipped open without pulling two limiting pins 505 at the same time, making the operation more convenient.

[0029] like Figure 1 and Figure 2 As shown, a limiting component 6 is installed inside the splitter frame 501. The limiting component 6 includes a limiting groove 601 opened at the bottom of the outer wall of one end of the splitter frame 501. A movable frame 602 is slidably inserted into the limiting groove 601. Several limiting wheels 603 are rotatably connected to the top inner wall of the movable frame 602 through bearings. A limiting wheel 603 is rotatably connected to the bottom inner wall of several partitions 502 through bearings. A bolt 604 is threadedly connected to the outer wall of one end of the movable frame 602. The bolt 604 fits against the inner wall of the limiting groove 601.

[0030] Push the movable frame 602 to one side, and the movable frame 602 will slide to one side along the limiting slide groove 601. As a result, the limiting wheel 603 will also be driven to move closer to another limiting wheel 603. The optical fiber between the two will be clamped, and under the action of the limiting wheel 603, the position of the optical fiber is restricted while also being adjustable. Finally, by rotating the knob to drive the bolt 604, the movable frame 602 can be driven to press against the inner wall of the limiting slide groove 601. Under the action of static friction, the positions of the movable frame 602 and the limiting wheel 603 are fixed.

[0031] like Figure 1 As shown, a number of equally spaced wiring terminals 4 are provided on the inner wall of one end of the pull frame 2, and the wiring terminals 4 are at the same level. Two wire holes 3 are opened on the outer walls of both sides of the pull frame 2.

[0032] like Figure 1 and Figure 4 As shown, the same positioning component 7 is installed between the placement box 1 and the pull frame 2, and the positioning component 7 is located on one side of the placement box 1.

[0033] The positioning component 7 includes two positioning rods 701 that are slidably inserted into one side of the top outer wall of the placement box 1. The top outer wall of the two positioning rods 701 is fixedly connected to the same connecting rod 703. Two slots 702 are opened on one side of the top outer wall of the pull frame 2. Both slots 702 are set in right-angled triangles. The corners of the two positioning rods 701 near the slope of the slots 702 are set as arc angles.

[0034] When the pull frame 2 is pulled outward, the positioning rod 701 first contacts the top wall of the pull frame 2 and cannot move. When the pull frame 2 is about to be pulled out, the positioning rod 701 will also enter the slot 702. Under the action of gravity, the positioning rod 701 slides down the slope of the slot 702. Then the inner wall of the slot 702 contacts the outer wall of the positioning rod 701, and the position of the pull frame 2 is restricted and cannot continue to move, preventing the pull frame 2 from directly leaving the inner cavity of the placement box 1. When the pull frame 2 enters the placement box 1 again, the slot 702 can lift the positioning rod 701 and move it upward, without affecting the normal movement of the pull frame 2.

[0035] This utility model provides a pull-out fiber optic distribution frame, the specific working principle of which is as follows:

[0036] When the device is in operation, the optical fiber is inserted into the pull frame 2 through the through hole 3, and the optical fiber is placed in several slots 502. Then, the baffle 503 is flipped so that it is close to the splitter frame 501. The insertion end of the spring 506 first contacts the inclined surface 510. As the baffle 503 moves down, the limiting pin 505 is guided outward by the inclined surface 510 and then contacts the outer wall of the splitter frame 501. When the baffle 503 and the splitter frame 501 are in contact, the spring 506 will drive the limiting pin 505 to insert into the corresponding slot. The position of plate 503 will be firmly restricted. To open plate 503, grasp guide frame 508 and lift it upwards. Since the position of plate 503 is relatively fixed, guide frame 508 drives limit pin 505 away from splitter frame 501 through extension column 509 until limit pin 505 disengages from the locking hole of splitter frame 501. Then plate 503 can be flipped open without pulling two limit pins 505 at the same time, making operation more convenient. Next, push moving frame 602 to one side. 02 Slides along the limiting groove 601 to one side, and the limiting wheel 603 is also driven to move closer to another limiting wheel 603. The optical fiber between the two will be clamped, and under the action of the limiting wheel 603, the position of the optical fiber is restricted while also being adjustable. Finally, by rotating the knob to drive the bolt 604, the moving frame 602 can be driven to press against the inner wall of the limiting groove 601. Under the action of static friction, the positions of the moving frame 602 and the limiting wheel 603 are fixed. When the pull frame 2 is pulled outward... The positioning rod 701 first contacts the top wall of the pull frame 2 and cannot move. When the pull frame 2 is about to be pulled out, the positioning rod 701 will also enter the slot 702. Under the action of gravity, the positioning rod 701 slides down the slope of the slot 702. Then the inner wall of the slot 702 contacts the outer wall of the positioning rod 701, and the position of the pull frame 2 is restricted and cannot continue to move, preventing the pull frame 2 from directly leaving the inner cavity of the placement box 1. When the pull frame 2 enters the placement box 1 again, the slot 702 can lift the positioning rod 701 and move it upward, without affecting the normal movement of the pull frame 2.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
