Description

Technical Field

[0001] The utility model relates to a field, in particular to a novel convenient optical fiber distribution frame. Background Art

[0002] Optical fiber distribution frames (ODFs) are used for the termination and distribution of trunk optical cables at the local end of optical fiber communication systems, and can conveniently realize the connection, distribution and scheduling of optical fiber lines. The patch panel is an important component of the optical fiber distribution frame. At present, the patch panel is mainly installed in the cabinet of the optical fiber distribution frame by screws. However, during maintenance, it is necessary to use tools such as screwdrivers to tighten the screws to remove or install the patch panel, which is inconvenient to operate. In addition, a large amount of dust will accumulate inside the optical fiber distribution frame after long-term use. Since the components and line layout inside the optical fiber distribution frame are relatively complex, the dust cleaning operation is very inconvenient. Therefore, a new type of convenient optical fiber distribution frame is developed. Utility Model Content

[0003] The purpose of the utility model is to provide a novel portable optical fiber distribution frame to solve the technical problems mentioned in the above background technology.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

A slide groove 4 is provided on the side of each of the two opposite mounting seats 3. A connection box 5 is slidably installed in the two opposite slide grooves 4. The two ends of the connection box 5 are respectively slidably matched with the slide grooves 4 on the corresponding two mounting seats 3. In this embodiment, each mounting seat 3 is provided with a mounting groove 6 on the inner side of the slide groove 4, and a wheel groove 7 is provided on the inner side of the mounting groove 6. Multiple groups of wheel seats 8 are evenly spaced and arranged inside each of the mounting grooves 6 at both ends of each of the connection boxes 5. A roller 9 adapted to the wheel groove 7 is rotatably installed on each group of the wheel seats 8.

[0019] A first vertical plate 10 is respectively provided at the upper part of each mounting seat 3 near the outer end, and a second vertical plate 11 is respectively fixedly provided at both ends of the upper part of each connection box 5 at positions corresponding to each first vertical plate 10. A first through hole 12 and a second through hole 13 of the same size and coinciding axis are respectively provided on each corresponding first vertical plate 10 and second vertical plate 11. A slide bar 14 is slidably installed in the second through hole 13, and a limit ring 15 is fixedly provided at the part of the slide bar 14 located between the first vertical plate 10 and the second vertical plate 11, and a spring 16 is sleeved at the part located between the second vertical plate 11 and the limit ring 15, and a pull ring 17 is fixedly provided at one end of the slide bar 14 located above the connection box 5.

[0020] A vertical lead screw 18 is rotatably mounted inside the box 1 near the inner end plate thereof, and a driving motor 19 for driving the lead screw 18 to rotate is mounted on the top plate of the box 1. A nut sleeve 20 threadedly connected to the lead screw 18 is mounted on the lead screw 18, and the outer side of the nut sleeve 20 is fixedly connected to a horizontal air blowing pipe 21, and a plurality of air blowing nozzles 22 are evenly spaced and mounted on the outer side of the air blowing pipe 21. In addition, two limit rods 23 are symmetrically fixedly mounted inside the box 1 along the lead screw 18, and two limit sleeves 24 slidably matched with the two limit rods 23 are symmetrically fixedly mounted on the inner side of the air blowing pipe 21.

[0021] One end of the upper portion of the air blowing pipe 21 is connected to one end of a retractable bellows 25, and the other end of the bellows 25 extends to the outside of the box 1 and is connected to the air outlet end of an induced draft fan 26 installed on the top plate of the box 1. Specifically, an air outlet pipe 27 connected to the other end of the bellows 25 is installed at the air outlet end of the induced draft fan 26, and an air filter 28 is provided at the connection portion between the air outlet pipe 27 and the bellows 25.

[0022] The working principle of the utility model is as follows: the connection box is installed between the two corresponding mounting seats in a pull-out manner. When the connection box needs to be connected for maintenance, it is only necessary to pull the pull rings on each slide bar inwardly to pull the slide bar out of the first through hole on the corresponding first vertical plate, and then the connection box can be pulled out from the mounting seat. When installing the connection box, each pull ring is also pulled so that the end of the slide bar does not interfere with the first vertical plate. When the connection box is inserted into the two mounting seats, the pull ring is released. Under the action of the restoring force of the spring, the end of the slide bar moves toward the direction of the first vertical plate and plugs and cooperates with the first through hole on the first vertical plate, thereby realizing the locking of the connection box. The connection box of the utility model does not require other tools to assist during disassembly and assembly, and is convenient and quick to load and unload.

[0023] In addition, the utility model further provides an air blowing pipe inside the box body of the wiring rack. The airflow introduced by the induced draft fan is transmitted to the air blowing pipe through the bellows and is sprayed out by the air blowing nozzle outside the air blowing pipe. When the driving motor drives the screw to rotate, the nut sleeve fixedly connected to the air blowing pipe maintains threaded cooperation with the lead screw, so that the air blowing pipe makes a linear reciprocating motion in the vertical direction together with the nut sleeve, and automatically blows away the dust at various positions inside the box body, thereby ensuring the cleanliness of the inside of the optical fiber wiring rack.
