Description

Technical Field

[0001] The invention belongs to the technical field of cabinet wire binding devices, and in particular relates to a wire binding structure of a server cabinet. Background Art

[0002] The server cabinet will store electronic components, and two electronic components need to be electrically connected through wires. In order to avoid the disorderly arrangement of wires in the cabinet, a common method is to use multiple cable ties to tie multiple wires into a bundle.

[0003] Although cable ties can effectively bind multiple wires and prevent the wires from being messy and loose, it is not convenient to use cable ties to bind wires. The reason is that when multiple wires are bundled into a bundle, it is not necessary to use only one cable tie to bind one end of the multiple wires. Instead, multiple cable ties are needed to bind the two ends and the middle of the multiple wires respectively. It can be seen that a bundle of wires requires at least three cable ties to be tied, and at least three times of tying. The number of tying times is large, and the operation is inconvenient.

[0004] In addition, it is inevitable that wires will need to be replaced during use. For example, when the load between electronic components increases, thicker wires need to be replaced. In this case, if one of the multiple wires bundled into a bundle needs to be replaced, the multiple wires need to be untied to facilitate the removal of the wire from the bundle for replacement. Cable ties are disposable items and do not have the function of untying. The only way to untie a bundle of wires is to cut off the multiple cable ties on the bundle; after untying the multiple wires, replace them with new wires, and then use multiple cable ties to re-bundle the multiple wires into a bundle. It can be seen that in the process of replacing wires, it is necessary to repeatedly cut and re-tie the cable ties, which is inconvenient to operate. Summary of the invention

[0005] A wire binding structure for a server cabinet of the present invention can bind a plurality of wires into a bundle at one time and avoid cutting the wire tie when unbinding.

[0006] A wire binding structure of a server cabinet of the present invention comprises a cabinet body, wherein a plurality of wire harness components are arranged in the cabinet body, and the wire harness components comprise: The equipment box is fixedly connected to the cabinet body; A plurality of wiring harness units are arranged in parallel on the equipment box in a horizontal direction; the wiring harness units include: The rack is movably mounted on the inner wall of the cavity of the equipment box, and the rack can move vertically; A pressure plate, fixedly connected to the lower end of the rack; The spring is located at the lower end of the pressure plate, the upper end is fixedly connected to the pressure plate, and the lower end is fixedly connected to the inner wall of the equipment box, and the spring is in a natural state; A perforation is provided on the upper surface of the device box; The cable tie is wound into a ring shape and fixedly connected to the upper end of the rack, and the upper end of the cable tie passes through the through hole; Also included is a drive assembly for moving the rack and the pressure plate downward as a whole.

[0007] Furthermore, the driving assembly comprises: A driving rod is rotatably connected to the device box, and the direction in which the multiple harness assemblies are arranged in parallel is assumed to be an X direction, and the axis of the driving rod is parallel to the X direction; A plurality of half gears are fixedly connected to the driving rod and are arranged one by one corresponding to the harness units; when viewed from the axis of the driving rod, each half gear has teeth on one half of its circumference and no teeth on the other half of its circumference; the half gears can mesh with the corresponding racks; The limit box is fixedly connected to the limit box; one end of the driving rod passes through the limit box; and an elastic mechanism for limiting the rotation of the driving rod is arranged in the limit box.

[0008] Because a half-size wheel is provided, the half gear and the rack can be disengaged. When the half gear and the rack are disengaged, the rack can move upward and reset under the elastic force of the spring. The rack resets, making the upper end diameter of the cable tie larger, making it more convenient to unlock multiple wires at the same time. Moreover, the meshing of the half gear and the rack can realize the simultaneous downward movement of multiple racks, realizing the simultaneous bundling of multiple wires.

[0009] Furthermore, two elastic mechanisms are provided, and a surface perpendicular to the end surface of the driving rod and along the vertical direction is assumed to be surface P, and the two elastic mechanisms are symmetrically arranged along surface P.

[0010] The resistance generated by the two elastic mechanisms is greater, ensuring that the elastic force of the spring cannot overcome the resistance generated by the elastic mechanism, so that the spring cannot rotate the drive rod. Only when the resistance of the elastic mechanism is overcome by human power to rotate the drive rod can the elastic force of the spring be restored.

[0011] Furthermore, the elastic mechanism comprises: The elastic sheet is in the limit box, the elastic sheet is elastic and can produce elastic deformation, and when the elastic sheet is not subjected to external force, the surface of the elastic sheet is parallel to the surface P; Two connecting seats are fixedly connected to the inner wall of the cavity of the limit box. The two connecting seats are respectively located at the upper end and the lower end of the elastic sheet. Both connecting seats are provided with card slots, and the two ends of the elastic sheet are embedded in the corresponding card slots. The limit block is fixedly connected to the driving rod. When the two elastic sheets are parallel to the plane P, the two elastic sheets abut against the two straight edges of the limit block.

[0012] Furthermore, the limiting block is in the shape of a waist.

[0013] When the arc-shaped edge of the waist-shaped structure abuts against the elastic sheet, the elastic sheet is compressed and deformed. At this time, the elastic sheet is in an unstable state. If the elastic sheet contacts the arc-shaped edge of the waist-shaped limit block, under the action of the elastic force of the elastic sheet, due to the unstable state of the elastic sheet, the limit block will continue to rotate until the two right-angled edges of the limit block contact the two elastic sheets. Therefore, the elastic sheet has the function of limiting the rotation of the limit block.

[0014] Beneficial effects:

[0015] This solution uses a half gear and a rack to retract the cable tie downward, thereby reducing the diameter of the ring at the upper end of the cable tie, allowing multiple wires to be bound in the ring of the cable tie. Multiple cable ties are uniformly driven by a driving rod, and multiple cable ties simultaneously reduce the diameter of the upper end ring, which can complete the binding of the wires at one time, making the cable binding more convenient.

[0016] To enlarge the diameter of the upper end of the cable tie, you only need to rotate the drive rod 180 degrees clockwise or counterclockwise, regardless of the direction of rotation of the drive rod. Under the elastic recovery of the spring, the rack can move upward, and the diameter of the upper end of the cable tie will be enlarged again, making untying more convenient.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See Figure 1 A wire binding structure of a server cabinet includes a cabinet body 1, in which a plurality of wire binding assemblies are arranged, each of which can bind a plurality of wires. For example, a wire binding assembly includes: Equipment Box 2, see Figure 2 , and is welded and fixed on the cabinet body 1. In this embodiment, the device box 2 is in the shape of a rectangular box with a cavity opened inside.

[0021] A plurality of wiring harness units are arranged in parallel on the equipment box 2 along the horizontal direction, that is, Figure 2 The left and right directions are arranged in parallel, and the number of the wiring harness units is N. Figure 2 , as a beam line unit, the beam line unit includes: Rack 3, see Figure 3 The movable card is arranged on the inner wall of the cavity of the equipment box 2, and the rack 3 can slide vertically. A plurality of teeth on the rack 3 are arranged vertically, and the rack 3 cannot slide out of the equipment box 2.

[0022] The pressure plate 4 is located in the cavity of the device box 2 and is integrally arranged at the lower end of the rack 3; the movable clamp is arranged on the inner wall of the cavity of the device box 2 and can move vertically as a whole with the rack 3.

[0023] The spring 5 is located below the pressure plate 4, the upper end of the spring 5 is bonded to the pressure plate 4 by glue, and the lower end of the spring 5 is bonded to the lower surface of the inner wall of the device box 2 by glue. The spring 5 is in a natural state.

[0024] The through hole 6 is provided on the upper surface of the device box 2 and communicates with the cavity of the device box 2; the aperture of the through hole 6 is relatively small, smaller than the diameter of the wire.

[0025] The cable tie 7 is wound into a ring shape with the head and tail connected. The spring 5 is in a natural state. The cable tie 7 is inserted into the perforation 6. The upper end of the cable tie 7 passes through the device box 2. The head and tail ends of the cable tie 7 are glued to the upper end of the rack 3 so that the cable tie 7 can maintain a ring shape. The cable tie 7 maintains Figure 3 state.

[0026] See Figure 3 When the rack 3 and the pressure plate 4 move downward as a whole, the spring 5 is first subjected to the downward pressure of the whole, and the spring 5 is compressed and deformed, causing the upper end of the cable tie 7 to gradually retract into the device box 2, and the diameter of the ring portion passing through the perforation 6 becomes smaller, and the purpose of bundling multiple wires in the cable tie 7 ring is achieved by tightening. Multiple cable tying units are tied at different positions of the wires to achieve bundling at different positions.

[0027] When the rack 3 and the pressure plate 4 move upward as a whole, the spring 5 rebounds naturally, causing the diameter of the portion of the cable tie 7 that passes through the through hole 6 to become larger again, and the cable tie 7 loosens the multiple wires again, thereby untying the wires.

[0028] A driving assembly is also provided for making the racks 3 and the pressure plates 4 of the multiple wiring harness units move downward as a whole at the same time; it can also release the racks 3 and the pressure plates 4, allowing the racks 3 and the pressure plates 4 to move upward at the same time under the action of the spring, thereby achieving simultaneous binding or unbinding of the wires.

[0029] The drive components include: Drive rod 8, see Figure 1 and Figure 3 , is rotatably connected to the device box 2 through a bearing, and the direction in which multiple harness assemblies are arranged in parallel is assumed to be the X direction; the axial direction of the driving rod 8 is parallel to the X direction, that is, Figure 2 In the left-right direction, the right end of the driving rod 8 passes through the device box 2.

[0030] Several half gears 9 are arranged in parallel along the axis of the driving rod 8, corresponding to each harness unit, and there are N of them, which are sleeved on the driving shaft and connected to the driving rod 8 as a whole by interference fit. Figure 3 From the perspective of the half gear 9, only half of the circumferential side wall of each half gear 9 is provided with teeth, and the other half of the circumferential side wall is not provided with teeth. Therefore, when looking at a half gear 9, the half gear 9 can mesh with the rack 3 of the corresponding wiring harness unit by its teeth, and can also disengage the rack 3 of the corresponding wiring harness unit through the non-toothed part.

[0031] The limit box 10 has a cavity inside, and the surface of the device box 2 on the side where the driving rod 8 passes through is defined as surface A, and the limit box 10 is welded and fixed on surface A. The driving rod 8 also passes through the limit box 10, and a handle is installed at one end of the driving rod 8 passing through the limit box 10, and the handle is used by the user to rotate the driving rod 8. The surface perpendicular to the end surface of the driving rod 8 and along the vertical direction is defined as surface P.

[0032] Two sets of elastic mechanisms are symmetrically arranged along the plane P. The elastic mechanism is used to limit the driving rod 8 from rotating freely. In this embodiment, the elastic mechanism is used to limit the driving rod 8 to rotate only 180 degrees each time.

[0033] The elastic mechanism includes: The elastic sheet 11 is in the limit box 10 . The elastic sheet 11 is a metal sheet. It is elastic and can produce elastic deformation. When no external force is applied, the surface of the elastic sheet 11 is parallel to the plane P.

[0034] The two connecting seats 12 are welded and fixed on the inner wall of the cavity of the limit box 10. The two connecting seats 12 are respectively located at the upper and lower ends of the elastic sheet 11. Both connecting seats 12 are provided with card slots, and the elastic sheet 11 is embedded in the card slots to ensure that the elastic sheet 11 and the two connecting seats 12 cannot be separated.

[0035] The stop block 13, in this embodiment, has a hole in the middle thereof, and is located in the stop box 10. Viewed from the axis of the driving rod 8, the stop block 13 is waist-shaped, with two opposite sides being semicircular arcs and the other two opposite sides being straight sides. When the two elastic sheets 11 are parallel to the plane P, the two elastic sheets 11 just abut against the two straight sides of the stop block 13.

[0036] The use of this device: The test personnel threaded multiple wires through multiple cable ties 7, that is, Figure 1 State, at this time, the half-scale wheel 9 is not engaged with the rack 3, such as Figure 3 shown.

[0037] Then the tester drives the driving rod 8 to rotate 180 degrees counterclockwise. As a harness unit, the driving rod 8, the half-scale wheel 9 and the limit block 13 rotate 180 degrees counterclockwise as a whole. Figure 4 The up and down directions of the middle limit block 13 are reversed. The half-scale wheel 9 gradually meshes with the rack 3 during the 180-degree rotation, and due to the meshing of the half-scale wheel 9 and the rack 3, the half-scale wheel 9 drives the rack 3 to move downward, so that the cable tie 7 moves downward, and finally, while the half-scale wheel 9 is kept meshing with the rack, the rack 3 moves downward, so that the cable tie 7 reduces the part extending out of the device box 2, thereby playing the role of binding the wires.

[0038] After the limit block 13 rotates 180 degrees, the straight edge of the limit block 13 abuts against the two elastic sheets 11 again, and the two elastic sheets 11 restrict the limit block 13 from rotating. Therefore, after the tester releases his hand, the half gear is engaged with the rack, and the elastic force of the spring cannot overcome the resistance of the two elastic sheets to rotate the half gear. Therefore, the spring cannot overcome the elastic force of the two elastic sheets 11 to restore to its original state, that is, the cable tie cannot restore to its original state, the cable tie always keeps the wires bound, and the upper end diameter of the cable tie cannot be enlarged to untie multiple wires.

[0039] If the cable tie 7 needs to loosen the wire, that is, untie it, the tester will turn the drive rod 180 degrees clockwise, or turn the drive rod 180 degrees counterclockwise again, so that the up and down direction of the limit block 13 is reversed. If it is rotated 180 degrees counterclockwise, the untoothed part of the half gear 9 will face the rack, so that the half gear and the rack 3 will be disengaged, and the spring will return to its original state. If it is rotated 180 degrees clockwise, the half gear 9 and the rack 3 will first remain engaged during this process. As the rotation angle approaches 180 degrees, the untoothed part of the half gear 9 will face the rack, so that the half gear and the rack 3 will be disengaged, and the spring will return to its original state. Each rotation of 180 degrees can achieve untying and bundling, which is very convenient to use.

[0040] The advantage of this solution is that the tester can tie and untie multiple wires at the same time by turning the driving rod. Compared with the situation where the cable tie cannot be untied, this solution saves a lot of time for tying and untying, and is more convenient to use. Moreover, untying can be achieved after each 180-degree rotation, which is simple to operate.

[0041] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
