Abstract
Description
Technical Field
[0001] The utility model belongs to the field of optoelectronic technology and specifically discloses an optical cable management device. Background Art
[0002] Optoelectronic devices are various functional devices made using the electro-photon conversion effect. They are the key and core components of optoelectronic technology, the frontier research field of modern optoelectronic technology and microelectronic technology, and an important part of information technology. Existing optoelectronic devices mostly use wires to connect to external energy sources. When multiple optoelectronic devices are used at the same time, the complex wires often become entangled, causing unnecessary trouble for maintenance.
[0003] When multiple strands of wires of different specifications are transmitted in parallel, the replacement and extraction of one line will often cause disturbances to other lines, causing the interfaces of other lines to fall off, get entangled, or the rubber to be damaged, etc. Moreover, if the tension of the wire is high, it will be difficult to extract it during replacement. If the wire is laid loosely, it will be more likely to get knotted and entangled with surrounding wires or brackets. Different wiring operators do not have a unified standard for the tightness of the wires, and it is difficult to perform standardized wire management work during maintenance, resulting in low maintenance efficiency and reduced wire life. Utility Model Content
[0004] In order to solve the problems in the background technology, the utility model provides an optical cable management device, and the specific technical solution is as follows:
[0005] It includes a rectangular wire management box with an upper opening, and a wire winding mechanism and a rotating reset mechanism fixed to the wire management box. The wire winding mechanism includes a cable clamp, a rotating shaft, a wire clamping wheel with a radial groove, a gear, a disc-shaped spring and a restraining cylinder. The rotating shaft and the restraining cylinder are both vertically fixed to the inner bottom surface of the wire management box, and the wire clamping wheel and the gear are fixed on the rotating shaft.
[0006] The cable clamps are fixed in pairs to the upper edges of the two pairs of side surfaces of the cable management box, and the center line of the cable clamps is perpendicular to the two pairs of side surfaces, passes through the clamping slots on the clamping wheel, and is orthogonal to the axis of the rotating shaft; the clamping wheel, the gear, the disc-shaped spring and the restraining cylinder all keep the axis coincident with the axis of the rotating shaft; the disc-shaped spring is placed in the restraining cylinder, the head end is fixed to the bottom of the rotating shaft, and the tail end is fixed to the side wall of the restraining cylinder;
[0007] The rotary reset mechanism includes a rack meshing with the gear, a rack meshing and clamping mechanism and a rack travel lock; the rack is parallel to the two pairs of side surfaces, and the rack meshing and clamping mechanism is fixed in pairs in the sunken grooves at the top of the other two pairs of side surfaces of the cable management box, which can provide support force on the vertical surface of the rack and spring clamping force on the horizontal surface; the rack travel lock is used for the locking connection between the rack and the rack meshing and clamping mechanism, and the rack cannot move relative to the rack meshing and clamping mechanism when locked.
[0008] The movement of the rack and pinion transmission pair gives the mainspring a pre-tensioning force (the tensioning force is released at the moment the rack is disengaged, automatically tensioning the optical cable). The size of the pre-tensioning force is determined by the stroke of the rack, and the stroke of the rack is determined by the position of the lock. In this way, the wiring personnel can ensure that the tension of the optical cable is consistent each time, avoiding knotting and entanglement. When the wire needs to be extracted during maintenance, the wire can be loosened by reverse operation.
[0009] Preferably, the rack meshing and clamping mechanism includes two sets of clamps respectively inserted into the two slots, each set of clamps includes a compression spring, a support shaft, a support block, and a limiting protrusion. The support shaft is perpendicular to the two pairs of side surfaces, and both ends are fixed to the two side walls of the slot in which the support shaft is inserted. The upper surface of the support block is horizontal and is sleeved outside the support shaft and is slidably connected to the support shaft. The limiting protrusion is fixed on the support block away from one end of the rotating shaft and abuts against the back side of the rack; one end of the compression spring abuts against one end of the slot away from the rotating shaft, and the other end abuts against the support block.
[0010] A clamp is arranged on the other two pairs of side walls to avoid interference between the action of the clamp and the gears and cables. The clamping force is balanced and no external torque is generated on the rack, which effectively prevents disengagement and tooth hitting during the process of pulling the rack.
[0011] Preferably, the rack travel lock is only arranged in the slot on one side, and includes a tension spring, a limiting hole set on the back of the rack, and a positioning pin passing through the limiting protrusion and slidably connected thereto. The axes of the limiting hole and the positioning pin are perpendicular to the rack and when the limiting hole is aligned with the positioning pin, the positioning pin can be inserted into the limiting hole. A handle is fixed to the non-insertion end of the positioning pin, one side of the limiting protrusion abuts the rack, and the other side fixes one end of the tension spring, and the other end of the tension spring is fixed on the handle.
[0012] The latch lock has a simple structure, is easy to understand and replace.
[0013] Preferably, a T-shaped groove is provided on the back side of the rack along the rack direction, a T-shaped guide rail is fixed on the limiting protrusion close to the back side of the rack, the T-shaped groove is engaged with the T-shaped guide rail and can slide on the T-shaped guide rail, and the positioning pin passes through the T-shaped guide rail and is slidably connected thereto.
[0014] The addition of the T-shaped guide rail better ensures the movement direction of the rack and avoids the rack from disengaging from the gear on the vertical plane during the pulling process.
[0015] Preferably, there are a plurality of limiting holes, which are arranged in a row along the axial direction of the rack.
[0016] In this way, the pre-tensioning force can be flexibly adjusted according to wires of different specifications.
[0017] Preferably, the wire-holding wheel comprises a circular disc and two winding posts parallel to the rotating shaft, the two winding posts are fixed to the edge of the upper surface of the circular disc at a distance of 180°, and the space between them constitutes the holding slot.
[0018] This slot has two uses. It not only ensures that different strands of wires are separated during wiring, but can also be used as a winding post and is easy to replace.
[0019] Preferably, there are multiple sets of winding mechanisms, and the rotating axes of each set of winding mechanisms are parallel and can ensure that the overall outer contour does not interfere during the winding operation.
[0020] The parallel arrangement of multiple wires takes up less space, and a set of racks and clamping systems can meet the tensioning requirements of multiple wires.
[0021] Compared with the prior art, the utility model has the following beneficial effects:
[0022] Through the design of the gear rack with a locking mechanism, the rack can be used to drive the gear to rotate to tighten the mainspring during wiring, and the meshing part of the rack and the gear can be loosened after wiring to release the mainspring to tighten the wire, which can ensure that the tension of the optical cable is consistent each time, avoiding knotting and entanglement. When the wire needs to be extracted during maintenance, the wire can be loosened by reverse operation, which improves the efficiency of wiring and maintenance. The device of the utility model has the characteristics of clever layout, simple structure, reliability, and easy assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on this embodiment, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] See also Figures 1 to 7 In an embodiment of the utility model, a cable arrangement device for optoelectronic equipment includes a cable management box 10, and a plurality of opposite cable clamps 9 are fixedly connected to the side walls at both ends of the cable management box 10. The cable clamps 9 are made of elastic plastic material, and the corners of the cable clamps 9 are rounded. A plurality of sequentially arranged constraint cylinders 19 are fixedly connected to the inner bottom of the cable management box 10, and each constraint cylinder 19 is connected to a vertically arranged rotating shaft 13 through a rotating reset mechanism. A disc 12 is fixedly connected to the upper end of each rotating shaft 13, and two winding posts 11 are fixedly connected to the upper surface of each disc 12, which are respectively located at either end of the diameter of the disc 12;
[0033] Slots 1 are respectively provided on the two side walls of the cable management box 10, a support shaft 2 is fixedly connected in each slot 1, a support block 6 is slidably connected to each support shaft 2, a compression spring 8 is sleeved on each support shaft 2, and the two ends of the compression spring 8 are respectively against the support block 6 and the side walls of the slot 1, and the two support blocks 6 are connected to multiple rotating shafts 13 by pushing the rotation reset mechanism.
[0034] See also Figure 4 and Figure 5 Each rotation reset mechanism includes a spring 21, which is located in the constraint tube 19. The bottom end of the rotating shaft 13 passes through the top side wall of the constraint tube 19 and extends into the constraint tube 19. The bottom end of the rotating shaft 13 is rotatably connected to the bottom side wall of the constraint tube 19 through a bearing. The outer end of the spring 21 is fixedly connected to the inner side wall of the constraint tube 19. The center end of the disc 12 is fixedly connected to the side wall of the rotating shaft 13. When the gear 15 drives the rotating shaft 13 to rotate under the action of external force, the rotating shaft 13 can drive the spring 21 to tighten. After that, when the gear 15 loses external force, the spring 21 can drive the rotating shaft 13 to rotate under the action of elastic reset.
[0035] See also Figure 1and Figure 4 The pushing and rotating device includes a rack 4 and two limiting protrusions 7. One end of the rack 4 is fixedly connected to a pull plate 3. A T-shaped slot 5 is provided on the side wall of the rack 4. The two limiting protrusions 7 are respectively fixedly connected to the upper sides of the two support blocks 6. A T-shaped guide rail 18 is fixedly connected to the side wall of each limiting protrusion 7. The two T-shaped guide rails 18 are both slidably connected to the T-shaped slot 5. A gear 15 is fixedly connected to the side wall of each rotating shaft 13. The rack 4 is meshed with multiple gears 15. The diameter of the disc 12 is larger than the diameter of the gear 15. The pull plate 3 can be grasped to push the rack 4 to the other side. The rack 4 can mesh and drive the multiple gears 15 to rotate during the movement process. The rotation of the multiple gears 15 can drive the mainspring 21 to be in a compressed and wound state through the rotating shaft 13.
[0036] Specifically, a locating pin 17 is passed through the side wall of one of the limiting protrusions 7, and one end of the locating pin 17 passes through the side walls of the limiting protrusion 7 and the T-shaped guide rail 18. A limiting hole 16 is provided on the side wall of the T-shaped slot 5, and one end of the locating pin 17 extends into the limiting hole 16. The other end of the locating pin 17 is fixedly connected to the handle 14. A tension spring 20 is sleeved on the locating pin 17, and the two ends of the tension spring 20 are respectively fixedly connected to the handle 14 and the side wall of the limiting protrusion 7. When the locating pin 17 is not located in the limiting hole 16, the rack 4 can slide along the T-shaped guide rail 18, and one end of the locating pin 17 is exactly located at the position of the limiting hole 16. Under the action of the tension spring 20, the locating pin 17 will enter the limiting hole 16, so that the limiting protrusion 7 and the rack 4 remain fixed at this time.
[0037] The working principle of the utility model is:
[0038] When multiple cables need to be arranged, the pull plate 3 can be first grasped to push the rack 4 to the other side. During the movement of the rack 4, the multiple gears 15 can be meshed and driven to rotate. The rotation of the multiple gears 15 can drive the mainspring 21 to be in a compressed and reeled state through the rotating shaft 13. When the mainspring 21 is in the maximum compressed and reeled state, one end of the positioning pin 17 is exactly located at the position of the limiting hole 16. Under the action of the tension spring 20, the positioning pin 17 will enter the limiting hole 16, so that the rack 4 remains fixed at this time;
[0039] Afterwards, one cable can be respectively inserted into two cable clamps 9 whose center lines are colinear, and then one end of the cable between the two cable clamps 9 is placed between the two winding posts 11 on the disc 12. Then, multiple cables can be placed in the same manner as above. Finally, the rack 4 is pulled away from the rotating shaft 13. Each spring 21 will then recover elastically and drive the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, the two winding posts 11 on the upper side of the disc 12 can continuously wind excess cables around the two winding posts 11, thereby quickly organizing and storing multiple redundant cables.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
