Description

Technical Field

[0001] The utility model relates to the technical field of bent network cable protection, in particular to a network cable bending protection structure. Background Art

[0002] The bend of the network cable refers to the bending or turning part formed during the laying or connection of the network cable due to the need to adapt to different wiring environments or device interface locations; when laying the network cable, due to space limitations (such as corners, behind furniture, etc.) or design requirements (such as aesthetics, saving space, etc.), the network cable often needs to be bent or turned. These bending or turning parts are the bends of the network cable. The protective structure of the bend of the network cable is an important part designed to protect the network cable from damage during the bending process. This protective structure usually takes into account the physical characteristics and usage environment of the network cable to ensure the transmission performance and service life of the network cable.

[0003] According to the Chinese patent CN202320204545.9, in the application, after the network cable body passes through the wire groove, the screw is rotated to drive the roller to rotate, and the excess network cable body is wound up, so that the excess network cable body is accommodated in the storage cylinder, thereby avoiding the occupation of space resources, and at the same time facilitating the storage cylinder to protect the network cable body. Since the screw is threadedly connected to the screw groove, the roller can be fixed after rotation;

[0004] Although the cable trough in the application can effectively solve the problem of inconvenient storage, when in use, due to the insufficient flexibility of the network cable or the small bending radius, the wire core may break at the bend, and the broken wire core will directly lead to network interruption and affect the normal use of the network. For this reason, we propose a protective structure for the bend of the network cable. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 A protective structure for a bent portion of a network cable, comprising a bent network cable insulating shell 1 and a network cable core 15, wherein the outer side of the network cable core 15 is sleeved with the bent network cable insulating shell 1, and further comprising:

[0029] A rounding structure provided on one side of the bending network cable insulating housing 1, the structure being used to reduce the bending curvature of the bending network cable insulating housing 1;

[0030] The sliding structure is arranged at the bottom of the bending network cable insulating shell 1, and the structure is used to control the state of the supporting structure.

[0031] Furthermore, the circular support structure includes a support plate 6, a first fixed block 9, a second fixed block 12 and a connecting rod 13. Four groups of support plates 6 are movably connected to the outer side of the bent network cable insulating shell 1. One side of the four groups of support plates 6 is fixedly connected to the second fixed block 12. Both ends of the second fixed block 12 are movably connected to two groups of connecting rods 13 on both sides through plug-in fixed shafts. The two groups of connecting rods 13 form a quadrilateral with the first fixed block 9 and the second fixed block 12. The side where the two groups of connecting rods 13 are close to each other is movably connected to the first fixed block 9 through a fixed shaft. Therefore, the downward movement of the sleeve 8 will also drive the first fixed block 9 to move downward together. The downward movement of the first fixed block 9 will be transmitted through the connecting rod 13, so that the four groups of support plates 6 connected to the second fixed block 12 start to move outward.

[0032] Furthermore, a sleeve 8 is fixedly connected to one side of the first fixed block 9, and a fixed column 4 is sleeved on the inner wall of the sleeve 8. Since an extrusion block 11 is fixedly connected to the outer side of the threaded rod 10, and the bottom of the extrusion block 11 is movably connected to the top of the sleeve 8, when the threaded rod 10 moves downward, it pushes the extrusion block 11 to squeeze the top of the sleeve 8 downward. After being subjected to downward pressure, the sleeve 8 will slide downward along the outer wall of the fixed column 4.

[0033] Furthermore, a threaded groove 14 is provided at the top of the fixed column 4, and a threaded rod 10 is threadedly connected to the inner wall of the threaded groove 14, and an extrusion block 11 is fixedly connected to the outer side of the threaded rod 10. The bottom of the extrusion block 11 is movably connected to the top of the sleeve 8. When it is necessary to reduce the bending curvature of the bent network cable insulating casing 1, by rotating the top of the threaded rod 10, since the threaded rod 10 is threadedly connected to the inner wall of the threaded groove 14, the rotational action will be converted into a linear motion of the threaded rod 10. Specifically, as the threaded rod 10 rotates, it will move downward along the threaded groove 14, and the extrusion block 11 will move up and down along the threaded groove 14.

[0034] Furthermore, two groups of auxiliary blocks 3 are fixedly connected to the outer side of the fixed column 4, and the two groups of auxiliary blocks 3 are placed crosswise to form a "cross" shape, and the tops of the two groups of auxiliary blocks 3 are movably connected to the bottom of the sleeve 8.

[0035] Furthermore, the sliding structure includes a movable groove 5 and a slider 7. Both ends of the two groups of auxiliary blocks 3 are provided with a movable groove 5. The inner wall of the movable groove 5 is movably connected with the slider 7, and the slider 7 is in an "I" shape. The top of the slider 7 is fixedly connected to the bottom of the support plate 6. Since the top of the slider 7 is fixedly connected to the bottom of the support plate 6, and the slider 7 is movably connected in the movable groove 5, the support plate 6 will slide open along the direction of the movable groove 5 while moving outward. As the support plate 6 slides open, they will apply an outward force to the bent part of the bent network cable insulating casing 1. This force will gradually reduce the bending curvature of the bent network cable insulating casing 1 until the bending degree required by the user is reached.

[0036] Furthermore, the bottoms of the two groups of auxiliary blocks 3 are fixedly connected to the corresponding positions of the outer sides of the fixing columns 4 with the base 2, and the base 2 is fixed to the outer sides of the fixing columns 4, thereby ensuring the stability of the entire device during operation.

[0037] Working principle:

[0038] In the initial state, the four groups of support plates 6 are in a contracted state, tightly attached to the outer side of the bent network cable insulating shell 1. At this time, the bent network cable insulating shell 1 maintains its original bending shape. At this time, the quadrilateral structure composed of the connecting rod 13, the first fixed block 9 and the second fixed block 12 is in a relaxed state, and no additional thrust is applied to the support plate 6; when it is necessary to reduce the bending curvature of the bent network cable insulating shell 1, by rotating the top of the threaded rod 10, since the threaded rod 10 is threadedly connected to the inner wall of the threaded groove 14, the rotational action will be converted into a linear motion of the threaded rod 10. Specifically, as the threaded rod 10 rotates, it will move downward along the threaded groove 14, and the extrusion block 11 will move up and down along the threaded groove 14. Since the extrusion block 11 is fixedly connected to the outer side of the threaded rod 10, and the bottom of the extrusion block 11 is movably connected to the top of the sleeve 8, when the threaded rod 10 moves downward, it will push the extrusion block 11 to squeeze the top of the sleeve 8 downward. After being subjected to downward pressure, the sleeve 8 will slide downward along the outer wall of the fixed column 4, so The downward movement of the sleeve 8 will also drive the first fixed block 9 to move downward together. The downward movement of the first fixed block 9 will cause the four groups of support plates 6 connected to the second fixed block 12 to start moving outward through the transmission action of the connecting rod 13. Since the top of the slider 7 is fixedly connected to the bottom of the support plate 6, and the slider 7 is movably connected in the movable groove 5, the support plate 6 will slide open along the direction of the movable groove 5 while moving outward. As the support plate 6 slides open, they will apply an outward force to the bending part of the bending network cable insulating shell 1. This force will gradually reduce the bending curvature of the bending network cable insulating shell 1 until it reaches the bending degree required by the user. The base 2 is fixed to the outside of the fixed column 4, ensuring the stability of the entire device during operation. In summary, the device rotates the threaded rod 10, and uses the linear motion of the threaded connection to convert it into the downward movement of the sleeve 8 and the first fixed block 9, and then realizes the sliding opening of the support plate 6 through the transmission action of the connecting rod 13 and the slider 7, thereby reducing the bending curvature of the bending network cable insulating shell 1.
