Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of cable bridge, in particular to a kind of multi-dimensional angle adjustable cable installation bridge system, which can be applied in different plane corner environment, realize the installation of cable in multidimensional space. BACKGROUND

[0002] In the field of cable installation technology, cable bridge as a device for managing and supporting cable line plays a crucial role in the neat arrangement and safety protection of cables within buildings. Cable bridges typically include various structures such as trough type, tray type, ladder type and net type, composed of supports, arms and installation accessories. They can be independently erected or laid on various building and pipe gallery supports to achieve neat and orderly arrangement of lines and support a large number of lines, making the appearance of internal lines more aesthetically pleasing.

[0003] However, existing cable bridges have some limitations in the installation process. For example, patent CN113972607A describes a trough type cable bridge that achieves the function of bending through the cooperation of two arc-shaped plates, improving the laying efficiency. However, this design may not be flexible enough in the installation of corners in practical applications, and is limited to flat installation, making it difficult to adapt to flexible turning needs in multidimensional space. In addition, patent CN220341970U provides a connection structure for sheet metal parts, which connects horizontal and vertical trough type cable bridges through sheet metal connectors, although it provides a detachable connection method, but there are still inconveniences in the installation and angle adjustment at the corner.

[0004] Another example is patent CN113991565A, which discloses a bendable high-strength cable bridge, including a switching bridge assembly, a terminal bridge and a splicing bridge, aiming to provide more angle installation options. However, this design may still face difficulties in adjusting the turning angle in practical applications, especially in complex spatial environments, making it difficult to achieve precise angle adjustment to adapt to different installation needs.

[0005] In summary, existing cable bridge technology performs well in flat installation, but has deficiencies in installation at corners and flexibility in turning in multidimensional space. This limits their application in modern building environments, especially in situations that require precise turning and angle adjustment in complex spaces. Therefore, it is necessary to develop a new type of cable bridge that can maintain installation efficiency while providing better turning flexibility and angle adjustment capability to meet the diverse needs of modern buildings for cable installation.

[0046] As Figures 1-9As shown, the present embodiment provides a multi-dimensional angle adjustable cable installation bridge system, which comprises a plurality of corner bridge units 100. The corner bridge unit 100 comprises a multi-dimensional angle adjustable cable installation bridge connection assembly, i.e. N inner connectors 10 and at least N-1 outer connectors 20, N being a natural number greater than 2. The inner connector 10 comprises a transverse inner support plate 11 and an inner side beam 12 extending upward from both sides of the inner support plate 11. The outer connector 20 comprises a transverse outer support plate 21 and an outer side beam 22 extending upward from both sides of the outer support plate 21. The inner spacing between the two outer side beams 22 of the outer connector 20 matches the outer spacing between the two inner side beams 12 of the inner connector 10. Each inner connector 10 and outer connector 20 are alternately distributed, with the outer side beam 22 located outside the inner side beam 12, and the angle adjustment between adjacent inner connectors 10 and outer connectors 20 is to bend each segment of the corner bridge unit 100. Each inner side beam 12 is provided with a pair of transverse first waist-shaped holes K1 at the same height, and each outer side beam 22 is provided with a pair of transverse second waist-shaped holes K2 at the same height. The two first waist-shaped holes K1 on the inner side beam 12 of each inner connector 10 are respectively opposite to the adjacent second waist-shaped holes K2 on the outer side beam 22 of the corresponding two outer connectors 20, and are fastened with fasteners to lock the bending angle. The inner and outer connectors are arranged to realize the inner and outer lap at the same time of angle change, thereby forming a continuous and stable corner structure, and the arrangement of the waist-shaped holes gives a fastening allowance, which can realize angle adaptive fastening by using the ability to move along the hole long axis.

[0047] As shown, Figures 1-2 As shown in the figure, in one specific embodiment of a corner bridge unit 100, the corner bridge unit 100 comprises N inner connectors 10 and N+1 outer connectors 20, and the specific number is 5 inner connectors 10 and 6 outer connectors 20. The corner bridge unit 100 is bent in a first vertical bending direction, which is shown as an outer arc bending from right to left from top to bottom. In this first vertical bending direction, at least one bottom angle f of the two adjacent outer connectors 20 approaches. In this scheme, this corner bridge unit 100 is only bent in one vertical dimension, so the two bottom angles f of the outer connectors 20 located on the same side are close to the bottom angle f of the adjacent outer connector 20. In a more preferred scheme, the two close bottom angles form a confrontation, thereby improving the stability of the structure.

[0048] As shown, Figures 3-4As shown, in another specific embodiment of a bend-angle cable tray unit 100, the bend-angle cable tray unit 100 includes N inner connectors 10 and N+1 outer connectors 20, specifically 5 inner connectors 10 and 6 outer connectors 20. The bend-angle cable tray unit 100 bends in a second vertical bending direction, exhibiting an inward concave arc bend from top to bottom and from right to left. In this second vertical bending direction, at least one apex angle e of two adjacent outer connectors 20 is close to each other. In this embodiment, the bend-angle cable tray unit 100 bends only in one vertical dimension, so the two apex angles e on the same side of the outer connectors 20 are close to the apex angle e of the adjacent outer connectors 20. In a more preferred embodiment, the two close apex angles e form abutments, thereby improving the stability of the structure.

[0049] like Figures 5-6 As shown, in another specific embodiment of a bend-angle cable tray unit 100, the bend-angle cable tray unit 100 includes N inner connectors 10 and N+1 outer connectors 20. The bend-angle cable tray unit 100 bends in an arc shape in a horizontal direction. In this embodiment, the bend-angle cable tray unit 100 bends only in one horizontal dimension, so the outer edge h of the outer beam 22 of the outer connector 20 located at the inner edge of the arc is close to the outer edge h of the outer beam 22 of the adjacent outer connector 20. In a more preferred embodiment, the two close outer edges form abutments, thereby improving the stability of the structure.

[0050] like Figure 7 As shown, in another specific embodiment of a bend-angle cable tray unit 100, the multi-dimensional angle adjustable cable tray system includes a bend-angle cable tray unit 100 and straight cable tray units 200 located on both sides thereof. The bend-angle cable tray unit 100 exhibits both vertical and horizontal bends, forming a serpentine multi-dimensional bending shape. In this bend-angle cable tray unit 100, there are N inner connectors 10 and N-1 outer connectors 20, with the inner connectors 10 on both sides abutting against the straight cable tray units 200. The outer connectors 20 in the bend-angle cable tray unit 100 approach each other at various points, including the apex, bottom, and outer edges. This is a comprehensive application combining the above three embodiments, further demonstrating the ingenuity of the technical concept.

[0051] Based on the above examples, it can be seen that the system can flexibly adjust the bending angle and direction of the cable installation bridge according to the needs and installation environment through the ingenious design of the inner and outer connectors 20, meet the diversified turning needs in complex wiring environment, make the assembly of the bridge unit extremely simple and fast, without complex on-site processing or customization, greatly shorten the construction period and reduce the installation cost. At the same time, corresponding to the setting of the waist-shaped hole, it ensures that the fastener can easily pass through and lock, further simplifies the installation process, improves the work efficiency, and at the same time enables the bridge connectors to be stably connected, and based on this stability, ensures that each inner support plate 11 of the bridge is in a smooth curve, ensuring smooth transition of the cable path and reducing the risk of cable wear and signal attenuation.

[0052] In addition, whether it is vertical bending or horizontal bending, the mutual approach or even interference design of the bottom angle, top angle or outer side of the adjacent outer connectors 20 significantly enhances the rigidity of the entire bridge structure, effectively resisting the adverse effects that may be caused by external factors such as vibration, wind, etc. This design not only guarantees the long-term stability of the bridge, but also provides a safer support environment for the cable.

[0053] Preferably, as shown in Figures 1-7 , the upper end of the outer side beam 22 is provided with a first edge T1 bent inward, and the first edge T1 extends above the inner side beam 12 and has a gap between them. This structure not only looks beautiful, but more importantly, it significantly enhances the stability of the entire structure. The edge carefully extends above the inner side beam 12 and leaves a gap between them. This design not only cleverly limits the up-and-down movement of the inner connector 10 in the vertical direction, effectively preventing loosening caused by vibration or external force, thereby greatly improving the stability and durability of the overall structure. In addition, the gap allows for flexibility in angle changes, and the presence of the edge also achieves an important safety function - edge protection. It should be noted that during installation or maintenance, workers often need to touch and operate these components, and sharp or exposed edges often cause accidental injuries such as hand clamping and cuts. By adding an edge, the sharp edge that may be exposed is completely wrapped inside, forming a smooth and harmless surface, greatly reducing the safety risk during operation and protecting the safety of workers.

[0054] Preferably, as shown in Figures 8-9 , the inner connector 10 and the outer connector 20 are formed by bending a long strip-shaped metal plate.

[0055] As shown in Figure 7As shown, the straight cable tray unit 200 includes a straight connector 30, which is U-shaped and includes a central transverse plate 31 and two vertical beams 32 on both sides. The inner spacing between the two vertical beams 32 is the same as the inner spacing between the two outer beams 22. This design not only enhances the stability of the structure but also facilitates docking with the angled cable tray unit 100.

[0056] The vertical beam 32 is provided with a third waist-shaped hole K3. When the inner connector 10 located at the outermost end of the angled cable tray unit 100 is adjacent to the straight connector 30, the inner connector 10 located at the outermost end of the angled cable tray unit 100 is located inside the straight connector 30. The first waist-shaped hole K1 of the inner connector 10 near the straight connector 30 can be opposite to the third waist-shaped hole K3, and a fastening connection is achieved by fasteners, thereby ensuring the continuity and stability of the entire cable tray system.

[0057] Preferably, such as Figure 7 As shown, the upper end of the vertical beam 32 is provided with an inwardly bent second edge T2, which extends above the inner beam 12 and has a gap between them. Preferably, the outer distance between the two vertical beams 32 is the same as the outer distance between the two outer beams 22, and the heights of the vertical beams 32 and the outer beams 22 are the same, so that the entire cable tray system has the same width. This not only makes the visual system more unified and harmonious and improves its integration, but also greatly facilitates space design and layout planning, meeting the dual requirements of flexibility and aesthetics of the cable tray system in different scenarios.

[0058] like Figures 1-9 As shown, each inner connector 10 and each outer connector 20 are of the same width. This makes each inner connector 10 and outer connector 20 universal, eliminating the need for special layout arrangements and making alignment and fastening operations during installation exceptionally simple, greatly improving work efficiency.

[0059] Furthermore, the pair of oblong holes on the inner beam 12 of the inner connector 10 and the pair of oblong holes on the outer beam 22 of the outer connector 20 are symmetrically arranged along the centerline. The sum of the distances between the two oblong holes on the outer beam 22 and the width side is equal to the distance between the pair of oblong holes on the inner beam 12 of the inner connector 10. This ingenious design ensures a tight fit between the cable tray units during connection, effectively avoiding installation difficulties caused by size mismatch, and further improving the installation convenience of the entire cable tray system.

[0060] like Figures 1-9As shown, the length of the waist hole of the inner beam 12 or the outer beam 22 is greater than one fifth of the width of the inner beam 12 or the outer beam 22 and less than two fifths of the width of the inner beam 12 or the outer beam 22. The length of the outer support plate 21 is greater than or equal to 4 times the width of the outer support plate 21. This design not only enhances the load capacity of the outer support plate 21, making the outer support plate 21 play a more stable supporting role in the bridge system. At the same time, it also makes the length-width ratio suitable to have greater angle switching capability.

[0061] Preferably, in the present embodiment, the length of the waist hole is three tenths of the width of the inner beam 12 or the outer beam 22, and the spacing between a pair of waist holes is one fifth of the width of the inner beam 12 or the outer beam 22. Such size selection not only ensures that the waist hole has sufficient adjustment space to adapt to different installation requirements, but also avoids the structural strength problems that may be caused by excessively large hole positions.

[0062] The above describes the multi-dimensional angle adjustable cable installation bridge system and the connecting assembly provided by the present application. The principles and implementation modes of the present application are described by applying specific examples. The above description of the embodiments is only used to help understand the present application and the core idea. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the principles of the present application, the present application can be improved and modified in many ways. These improvements and modifications also fall within the protection scope of the claims of the present application.
