Description

Technical Field

[0001] The present application relates to the technical field of optical fiber distribution frames, and in particular to a combined adjustable optical fiber distribution frame. Background Art

[0002] The patch panel is used for terminal user lines or relay lines, and can allocate and connect them. The patch panel is the most important component in the management subsystem, and is the hub for cross-connecting the vertical trunk line and horizontal wiring subsystems. The patch panel is usually installed on the control cabinet. The fiber optic control cabinet connects a large number of optical fibers, and a fiber optic patch panel is required to arrange and organize the optical fibers to prevent them from intertwining and ensure the convenience of later maintenance and replacement.

[0003] When the existing patch panel is in use, the optical fiber is usually wound and stored in the tray, and then the connector at one end of the optical fiber is connected to the interface of the patch panel. The bare fiber and the pigtail are also required to be straightened and wound in the patch module. However, during the winding process, the bare fiber and the pigtail are prone to bending and breaking at the fusion joint, which increases the workload for subsequent troubleshooting and has low troubleshooting efficiency. If the bare fiber and the pigtail are first wound on the module and then fusion-spliced, a long part needs to be reserved at the fusion joint and cannot be wound.

[0004] At the same time, the pipeline will bend downward under the action of gravity at the connection point. Different diameters of optical fibers require different minimum bending diameters. Optical fibers with larger diameters are prone to bending and damage.

[0005] Therefore, a combined adjustable optical fiber distribution frame is needed to solve the above problems. Summary of the invention

[0006] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0007] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a combined adjustable fiber optic distribution frame, including: a frame body, a mounting rail is vertically arranged in the frame body, and a distribution box is installed on the mounting rail; a socket is arranged on the front side of the distribution box to connect the optical cable connector; a wiring port is opened on the rear side of the distribution box for connecting the bare fiber; a winding component is arranged in the distribution box and used to wind the pigtail and the bare fiber for arrangement; the wiring component is arranged in the distribution box and used to increase the length of the connection when welding the pigtail and the bare fiber to facilitate welding, and at the same time, after the welding is completed, the pigtail and the bare fiber are tightened to avoid bending and winding at the welding position; the distribution box includes: a box body and a mounting plate slidably arranged in the box body, the front of the mounting plate The side is fixedly connected with a front side plate, and the front side plate and the mounting plate form a pull-out drawer structure, and the socket is arranged on the front side surface of the front side plate; the winding component comprises: a first slide groove and a second slide groove with the same direction are opened on the mounting plate, a winding block is slidably arranged in the first slide groove, a plurality of winding rails are arranged on the winding block, the plurality of winding rails have the same shape and are proportionally scaled, and the plurality of winding rails are proportionally reduced from bottom to top on the winding block; a symmetrical block is slidably arranged in the second slide groove, a plurality of symmetrical rails are arranged on the symmetrical block, the plurality of symmetrical rails have the same shape and are proportionally scaled, and each symmetrical rail is proportionally enlarged from bottom to top on the symmetrical block; wherein, the winding rail and the symmetrical rail are both "U"-shaped structures, which are used for winding pigtails and bare fibers, and the winding block and the symmetrical block move closer or farther away by sliding.

[0008] By setting the winding block and winding rail, symmetrical block and symmetrical rail, the pigtail and bare fiber can be wound, and the fusion position of the spiral and the pigtail can be adjusted to the semicircular position of the winding rail. When welding, the winding rail is flipped upward to raise the connection position, so that the connection point protrudes, which is convenient for welding.

[0009] Furthermore, a partition plate is fixedly arranged on the mounting plate, a channel is formed on the partition plate, guide cylinders with horn structures are arranged at both ends of the channel, a plurality of guide plates for guiding the pigtails are fixedly arranged on one side of the mounting plate close to the front side plate, a support structure for supporting the pigtail plate is fixedly connected to the front side plate, the support structure comprises: a frame plate fixedly arranged on the front side plate and located at the socket position, a placement groove is formed on the frame plate for the optical fiber to be placed, the placement groove has an opening facing upward, a support plate is slidably connected to the frame plate, a measuring groove is also formed on the support plate for the optical fiber to be placed, and the opening of the measuring groove is smaller than the opening of the placement groove.

[0010] With the frame plate and support plate, when the diameter of the optical fiber cable is large, the optical fiber is prone to bend and damage. Therefore, when the optical fiber line is placed in the measuring groove, the optical fiber cable with a smaller diameter directly passes through the placement groove and the measuring groove without contacting the support plate. When the optical fiber line with a larger diameter is placed in the placement groove, it will contact the side wall of the measuring groove, thereby pushing the support plate.

[0011] Furthermore, a supporting arc plate is hinged on the frame plate, and an adjustment frame is slidably arranged on the frame plate. A sliding rod is fixedly connected to the adjustment frame and slides with the frame plate. One end of the sliding rod passes through the frame plate and is fixedly connected with a retaining ring. A tension spring is arranged between the retaining ring and the frame plate, and both ends of the tension spring are respectively fixedly connected to the retaining ring and the frame plate. The adjustment frame abuts against a side of the supporting arc plate away from the center of the placement groove for pushing the supporting arc plate. The support plate is located between the frame plate and the retaining ring and abuts against the retaining ring.

[0012] By setting up the support arc plate and adjustment frame, when the diameter of the optical fiber line is small, the support arc plate will not flip up, which is convenient for normal plugging and unplugging of wiring. When the diameter of the optical fiber line is large, the adjustment frame pushes the support arc plate so that the support arc plate supports the photovoltaic line to avoid excessive bending.

[0013] Furthermore, the winding rail is fixedly connected to an installation shaft that rotates with the winding block, and the installation shaft is sleeved with a limiting wheel that coaxially slides with it. The limiting wheel is located in the inner cavity of the winding block, and a working spring is connected between the limiting wheel and the inner cavity of the winding block. The two ends of the working spring are respectively fixedly connected to the limiting wheel and the inner cavity wall of the winding block.

[0014] Through the installation shaft and the limit wheel, when the winding block is pulled out of the box body along with the front side plate, the rack drives the gear and the driving shaft to rotate, so that the elliptical head pushes the limit block, and then the installation shaft rotates under the action of the working spring. At this time, the limit head is out of the limit slot position, and then the limit block is pressed toward the limit wheel under the action of the reset spring. When the welding is completed, the winding rail is pushed to rotate and return to the horizontal state. At this time, the limit head is opposite to the limit slot, and the limit head returns to the limit slot to limit the winding rail.

[0015] Furthermore, a limiting groove is provided on the limiting wheel, and the limiting block is slidably connected in the inner cavity of the winding block. The limiting block has a limiting head for embedding into the limiting groove, and a driving shaft is rotatably connected to the winding block, and an elliptical head for pushing the limiting block is fixedly connected to the driving shaft, and a reset spring is connected between the limiting block and the inner cavity wall of the winding block, a first rack is fixedly connected to the bottom wall of the box body, a threaded sleeve is threadedly connected to the winding block, the threaded sleeve and the driving shaft slide together along the axis, and a gear is connected to the threaded sleeve through a ratchet piece, and the gear is meshed with the first rack.

[0016] By setting the gear and the rack, when the winding block is pulled toward the outside of the box body by the front side plate and the mounting plate, the gear drives the threaded sleeve to rotate through the ratchet piece. When the winding block is retracted into the box body along with the mounting plate and the front side plate, the rack cannot drive the gear to rotate.

[0017] Furthermore, the winding rail includes a mounting portion rotatably matched with the winding block and a track portion, the track portion having a semicircle and straight ends located at both ends of the semicircle, the winding rail having a mounting groove for embedding the pigtail fiber and the bare fiber, so that the pigtail fiber and the bare fiber are limited in position on the winding rail, and hinge seats are fixedly connected to the two side walls in the mounting groove, a hinge shaft is hinged on the hinge seat, a stop wheel for limiting the pigtail fiber and the bare fiber is rotatably connected to the hinge shaft, a limiting spring is connected between the hinge shaft and the side wall of the mounting groove, a connecting rod is fixedly connected to the mounting portion, one end of the connecting rod slides and slidably matches with the track portion, and a winding spring is fixedly connected between one end of the connecting rod and the track portion.

[0018] By setting the stop wheel, when the winding rail moves along the first slide groove toward the symmetrical block, the connecting ends of the pigtail and the bare fiber can extend from the semicircular part of the winding rail, which is convenient for welding, and the stop wheel guides the pigtail and the bare fiber.

[0019] Furthermore, a second rack located at the lower side of the symmetrical block is fixedly connected to the inner bottom wall of the box body, a threaded rod is threadedly connected to the symmetrical block, one end of the threaded rod is connected to an engaging wheel through a ratchet piece, and the engaging wheel is engaged with the second rack.

[0020] Through the threaded rod, meshing wheel and ratchet part, when the symmetrical block moves into the box body along with the mounting plate and the front side plate, the meshing wheel is driven to rotate through the second rack and the ratchet part, and then the threaded rod is driven to rotate, so that the symmetrical block slides along the second sliding groove to the side away from the winding rail.

[0021] The beneficial effects of this application are:

[0022] 1. By setting the winding block and winding rail, symmetrical block and symmetrical rail, the pigtail and bare fiber are wound, and the fusion position of the spiral and the pigtail is adjusted to the semicircular position of the winding rail. When welding, pull the front side plate so that the front side plate and the mounting plate are moved and pulled out of the box body, and the winding rail is flipped upward to raise the wiring position, so that the wiring point is protruding, which is convenient for welding.

[0023] 2. Through the support arc plate and adjustment frame, when the diameter of the optical fiber line is small, the support arc plate will not flip up, which is convenient for normal plugging and unplugging wiring. When the diameter of the optical fiber line is large, the adjustment frame pushes the support arc plate so that the support arc plate supports the photovoltaic line to avoid excessive bending.

[0024] 3. By setting up the stop wheel, when the winding rail moves along the first slide groove toward the symmetrical block, under the guidance of the stop wheel, the connecting ends of the pigtail and the bare fiber can extend from the semicircular part of the winding rail, which is convenient for welding. The stop wheel guides the pigtail and the bare fiber.

[0025] 4. Through the provided threaded rod, meshing wheel and ratchet part, when welding is completed, the meshing wheel is driven to rotate through the second rack and ratchet part, and then the threaded rod is driven to rotate, so that the symmetrical block slides along the second sliding groove to the side away from the winding rail, and the pigtail fiber and bare fiber extending from the welding point are retracted. At the same time, when retracting, the welding position moves from the semicircular part to the straight end, so as to avoid the welding position being fragile and damaged due to bending.

[0045] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0046] Reference Figure 1-10 A combined adjustable optical fiber distribution frame includes: a frame body 100, a mounting rail 101, a distribution box 102, a socket 103, a connection port 104, a bare fiber 105, a pigtail 106, a mounting plate 107, and a front side plate 108. The mounting rail 101 is vertically installed in the frame body 100, and the distribution box 102 is fixedly installed on the mounting rail 101 by bolts. The combination is adjusted by adjusting the position of the distribution box 102. The distribution box 102 includes a box body 109 and an upper cover plate 110, a front side plate 108 on the front side of the box body 109, and a mounting plate 107 that slides vertically in the box body 109, and the front side of the mounting plate 107 is fixedly connected to the front side plate 108. The sockets 103 are evenly distributed on the front side plate 108. The front side plate 108 and the mounting plate 107 form a drawer structure that can be pulled out. When welding is required, the mounting plate 107 can be pulled out by pulling the front side plate 108. The mounting plate 107 is provided with a first slide groove 111 and a second slide groove 112 arranged in the same direction. A winding block 113 is slidably connected in the first slide groove 111, and a plurality of winding rails 114 with a "U"-shaped structure are rotatably connected to the winding block 113. A symmetrical block 115 is slidably connected to the second slide groove 112, and a plurality of symmetrical rails 116 with a "U" structure are fixedly arranged on the symmetrical block 115. The bare fiber 105 and the pigtail 106 are wound between the winding block 113 and the symmetrical block 115 for convergence. The plurality of winding rails 114 are of the same shape and size and are proportionally scaled. The plurality of winding rails 114 are proportionally reduced from bottom to top on the winding block 113; the plurality of symmetrical rails 116 are of the same shape and size and are proportionally scaled. Each symmetrical rail 116 is proportionally enlarged from bottom to top on the symmetrical block 115. The pigtails 106 and bare fibers 105 are bundled by winding them on the winding rail 114 and the symmetric rail 116. A plurality of guide plates 117 for guiding the pigtails 106 are fixedly arranged on one side of the mounting plate 107 near the front side plate 108. The guide plates 117 are arc-shaped plate structures to prevent the optical fibers from being bent too much.

[0047] The winding rail 114 on the lower side does not interfere with the winding rail 114 on the upper side by rotating.

[0048] The mounting plate 107 is also provided with a partition plate, on which a channel is provided, and guide cylinders 118 of a horn structure are provided at both ends of the channel. A plurality of guide plates 117 for guiding the pigtail 106 are fixedly provided on one side of the mounting plate 107 close to the front side plate 108, and the guide plates 117 are respectively located at the connection port 104. Since the external optical fiber line is directly inserted into the position of the socket 103 through a connector, but due to the different diameters of the optical fiber bundle, the larger the diameter, the larger the minimum bending angle of the optical fiber bundle, so it is necessary to avoid the failure of the optical fiber bundle due to bending due to gravity, and the following solution is adopted.

[0049] A frame plate 119 is fixedly arranged at the position of the socket 103 on the front side plate 108. The frame plate 119 is a concave plate-shaped structure, and has a placement groove 120 that opens upward. When the optical fiber harness is connected, the harness will fall into the placement groove 120. A support plate 121 is slidably arranged on the frame plate 119. The support plate 121 is also provided with a test groove 122 that opens upward. The opening of the test groove 122 is smaller than the placement groove 120. The frame plate 119 is also hinged with three support arc plates 123 that surround the left and right sides and the lower side of the placement groove 120, and the optical fiber is clamped and supported by the support arc plates 123. An adjustment frame 124 is slidably arranged on the frame plate 119, and a sliding rod 125 is fixedly connected to the adjustment frame 124 and is slidably matched with the frame plate 119. One end of the sliding rod 125 passes through the frame plate 119 and is fixedly connected to a retaining ring 126. A tension spring 127 is arranged between the retaining ring 126 and the frame plate 119, and both ends of the tension spring 127 are respectively fixedly connected to the retaining ring 126 and the frame plate 119. The adjustment frame 124 abuts against a side of the support arc plate 123 away from the center of the placement groove 120. The tension spring 127 pushes the adjustment frame 124, so that the adjustment frame 124 pushes the support arc plate 123. When the diameter of the optical fiber is too large, the support plate 121 will be pushed in the process of falling into the placement groove 120, so that the support plate 121 no longer supports the retaining ring 126, and then the adjustment frame 124 is driven to move under the action of the tension spring 127.

[0050] When the pigtail 106 and the bare fiber 105 are welded, in order to avoid offline winding after the welding is completed, which is easy to damage the welding position, the welding needs to be performed after the winding is completed. However, the cable position cannot be adjusted after the winding is completed, resulting in welding failure. To solve the above problem, the following solution is adopted.

[0051] The winding rail 114 includes a mounting portion 128 that rotates with the winding block 113 and a track portion 129, and the track portion 129 has a semicircular shape and straight ends at both ends of the semicircular shape. The fusion position of the pigtail 106 and the bare fiber 105 is located at the middle end of the semicircular position. The winding rail 114 and the symmetrical rail 116 have mounting grooves 130 for the pigtail 106 and the bare fiber 105 to be embedded, so that the pigtail 106 and the bare fiber 105 are positioned at the upper limit of the winding rail 114. The mounting portion 128 is fixedly connected with a mounting shaft 131 that rotates with the winding block 113, so that the winding rail 114 can rotate around the mounting shaft 131, and the wiring position can be rotated to the upper position, which is convenient for the fusion work. At the same time, since the multiple winding rails 114 are of different sizes, there will be no obstruction between the winding rails 114.

[0052] When welding, the front side plate 108 needs to be pulled so that the mounting plate 107 , the winding rail 114 , and the symmetrical rail 116 are all moved out of the box body 109 .

[0053] During winding, the pigtail 106 and the bare fiber 105 are closely attached to the winding rail 114, and a fusion length needs to be reserved. However, the fusion length affects the neatness of the box, so the following solution is adopted.

[0054] A coaxially sliding limiting wheel 132 is sleeved on the mounting shaft 131, and the limiting wheel 132 is located in the inner cavity of the winding block 113. A working spring 133 is connected between the limiting wheel 132 and the inner cavity of the winding block 113. Both ends of the working spring 133 are respectively fixedly connected to the limiting wheel 132 and the inner cavity wall of the winding block 113. A limiting groove 134 is provided on the limiting wheel 132, and a limiting block 135 is slidably connected in the inner cavity of the winding block 113. The limiting block 135 has a limiting head 136 for embedding into the limiting groove 134. A driving shaft 137 is rotatably connected to the winding block 113, and an elliptical head 138 for pushing the limit block 135 is fixedly connected to the driving shaft 137. A reset spring 139 is connected between the limit block 135 and the inner cavity wall of the winding block 113. A first rack 140 is fixedly connected to the inner bottom wall of the box body 109. A threaded sleeve 141 is threadedly connected to the winding block 113. The threaded sleeve 141 and the driving shaft 137 slide together along the axis. A gear 142 is connected to the threaded sleeve 141 through a ratchet piece, and the gear 142 meshes with the first rack 140.

[0055] The two side walls in the installation groove 130 are fixedly connected with hinge seats 143, hinge shafts 144 are hinged on the hinge seats 143, and stoppers 145 for limiting the positions of the pigtail 106 and the bare fiber 105 are rotatably connected to the hinge shafts 144. A limit spring 146 is connected between the hinge shaft 144 and the side wall of the installation groove 130. A connecting rod 147 is fixedly connected to the installation part 128, one end of the connecting rod 147 slides and cooperates with the track part 129, and a winding spring 148 is fixedly connected between one end of the connecting rod 147 and the track part 129. When winding, the optical fiber is embedded in the installation groove 130, and the optical fiber is inserted into the installation groove 130 under the action of the limit spring 146.

[0056] When the front side plate 108 is pulled to make the mounting plate 107 and the winding block 113 move out of the box body 109, the first rack 140 drives the threaded sleeve 141 to rotate through the gear 142, so that the winding block 113 moves in the first slide groove 111 toward the symmetrical block 115, and the connection end of the bare fiber 105 and the pigtail 106 is extended. When the threaded sleeve 141 drives the driving shaft 137 to rotate, under the action of the elliptical head 138, the limit head 136 is separated from the limit groove 134. At this time, the working spring 133 is in a torsion state. Under the action of the working spring 133, the winding rail 114 rotates to a vertical state, and the limit head 136 will not return to the limit groove 134. The reset spring 139 is compressed to facilitate welding. After the welding is completed, the winding rail 114 is pushed back to the initial state. At this time, under the action of the reset spring 139, the limit head 136 continues to be embedded in the limit groove 134.

[0057] After the fusion splicing is completed, the excess bare fiber 105 and the pigtail fiber 106 need to be bundled and the fusion splicing position should be prevented from being bent further. The following solution is adopted.

[0058] A second rack 149 located at the lower side of the symmetrical block 115 is also fixedly connected to the inner bottom wall of the box body 109 , a threaded rod 150 is threadedly connected to the symmetrical block 115 , one end of the threaded rod 150 is connected to a meshing wheel 151 via a ratchet member, and the meshing wheel 151 meshes with the second rack 149 .

[0059] When the symmetrical block 115 moves out of the box body 109, the meshing wheel 151 will not drive the threaded rod 150 to rotate. When the symmetrical block 115 moves into the box body 109, the meshing wheel 151 drives the threaded rod 150 to rotate, so that the symmetrical block 115 moves away from the winding block 113, thereby pulling the bare fiber 105 and the pigtail fiber 106, and making the fusion position leave the semicircular bending area.

[0060] Working or installation process:

[0061] 1. Wind the pigtail 106 and the bare fiber 105 on the winding rail 114 and the symmetrical rail 116. The welding position is located in the middle of the semicircular area of ​​the winding rail 114. When welding, pull out the front side plate 108 to move the winding block 113, and then drive the winding block 113 to move toward the symmetrical block 115, so that the welding position of the pigtail 106 and the bare fiber 105 is extended. At the same time, the winding rail 114 is rotated to a vertical state, so that the welding position is facing upward, which is convenient for welding;

[0062] 2. The pigtails 106 and bare fibers 105 on each winding rail 114 are welded in turn. After welding, the winding rail 114 can be pushed down to push the front side plate 108 back into the box body 109, which will drive the symmetrical block 115 to move away from the winding block 113, thereby pulling the bare fiber 105 and the pigtail 106, and making the welding position leave the semicircular bending area.
