Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering technology, specifically a cable surplus management device for low-voltage engineering. Background Technology

[0002] In intelligent building cabling systems, multi-layer cable hierarchical management technology has gradually replaced traditional extensive cabling. However, existing solutions still have significant drawbacks: when maintenance of lower-layer cables is required, upper-layer cables and their supporting structures often need to be moved laterally as a whole. Traditional cabling systems lack dedicated cable slack storage designs, and the taut cables cannot provide sufficient space for lateral movement of upper-layer cables. This results in insufficient storage space for upper-layer cables during lower-layer cable maintenance, making flexible relocation impossible. Forced operation can easily lead to insulation damage and signal attenuation due to cable pulling, severely restricting the operation and maintenance efficiency and reliability of the integrated cabling system. Therefore, a comprehensive solution that combines slack storage, easy flexible hierarchical relocation, and efficient cable management is urgently needed. Utility Model Content

[0003] To address the problem in the aforementioned multi-layer cable hierarchical management technology that the lower-layer cables cannot be flexibly moved during maintenance due to insufficient storage capacity of the upper-layer cables, this application provides a comprehensive solution that combines ample storage, convenient hierarchical flexible relocation, and efficient cable management.

[0004] The purpose of this utility model is to provide a cable surplus management device for low-voltage engineering, comprising:

[0005] The substrate is supported by a continuous wavy surface formed by stamping, which includes alternating crests and troughs; the radius of curvature R of the crests and troughs satisfies: R≥8Dmax, where Dmax is the maximum outer diameter of the cable passing through.

[0006] A detachable corrugated baffle assembly includes multiple sets of parallel ABS engineering plastic baffles, wherein the ABS engineering plastic baffles are configured as continuous corrugated surfaces, and the waveform curvature matches the supporting substrate.

[0007] The cover plate assembly covers the removable corrugated baffle assembly and matches the waveform curvature of the supporting substrate, together forming a closed cable channel;

[0008] A fixing post is provided on the lower side of the crest and the upper side of the trough, and is connected to the supporting base plate by a connecting rib. A fixing column is provided at the lower part of the fixing post, and the fixing column is inserted into the bottom plate of the wiring groove for fixed connection.

[0009] Preferably, the bottom surface of the fixing pile is flush with the bottom surface of the supporting base plate in the assembled state, and the top surface is flush with the top surface of the cover plate assembly in the assembled state. A connecting hole is provided on the upper part of the fixing pile, and the connecting hole is used to fix the upper fixing column.

[0010] Preferably, the ABS engineering plastic partition includes a partition body and connecting ends at both ends, wherein the cross-sectional thickness of the connecting ends is less than the cross-sectional thickness of the partition body.

[0011] Preferably, the supporting substrate includes a substrate body, and the substrate body is provided with bottom fixing grooves that are the same number as the number of ABS engineering plastic partitions. The shape of the bottom fixing grooves is consistent with the waveform of the ABS engineering plastic partitions. The cross-sectional width of the bottom fixing grooves is smaller than the thickness of the partition body and larger than the cross-sectional thickness of the connecting end.

[0012] Preferably, the cover plate assembly is provided with a top fixing groove that is the same number as the ABS engineering plastic partitions. The shape of the top fixing groove is consistent with the waveform of the ABS engineering plastic partitions. The cross-sectional width of the top fixing groove is smaller than the thickness of the partition body and larger than the cross-sectional thickness of the connecting end.

[0013] Preferably, the cable slack management device includes at least one or more sets of the removable wave diaphragm assemblies with crests and troughs, and the matching support base plate and cover plate assembly, and includes at least one or more layers.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In terms of slack storage and release, both the supporting substrate and the detachable corrugated baffle assembly are continuous corrugated surfaces with a curvature radius R ≥ 8Dmax at the crests and troughs. This unique design provides ample space for the natural bending of cables, and a large amount of cable slack is stored in an orderly, corrugated pattern. When it is necessary to move the upper layer cables laterally for maintenance or to change the lower layer cables, simply remove the corresponding corrugated baffle, and the stored cable slack will be quickly released. The upper layer cables can then be moved laterally easily without any pulling on the cables. This effectively avoids problems such as insulation damage and signal transmission attenuation caused by pulling, greatly improving the safety and convenience of cable maintenance and modification operations.

[0016] 2. From the perspective of cable classification and protection, the supporting substrate and cover plate assembly work closely together, combined with the detachable corrugated baffle assembly, to construct multiple independent cable storage channels. Each channel is isolated from the others, allowing for the separate arrangement of cables of different types and functions, essentially creating a dedicated "room" for each cable. This echoes the concept of cable organization pursued in previous patents, fundamentally preventing cables from becoming tangled and interfering with each other, and facilitating quick identification and management of each cable during later maintenance. Simultaneously, the enclosed cable channels prevent the intrusion of dust, moisture, and other impurities, providing a good operating environment for the cables and extending their service life.

[0017] 3. The fixing piles play a crucial role in the ease of installation, fixation, and maintenance of the device. The fixing piles are securely connected to the supporting base plate via connecting stiffeners, and the lower fixing posts are inserted into the bottom plate of the wiring trough to reliably fix the entire device, ensuring that it will not shift or shake even in complex environments. Furthermore, this structural design eliminates the need for additional rigid connections between the partitions, greatly facilitating the assembly and disassembly of the device. During disassembly, the cover plate assembly is removed first, followed by easy removal of each partition piece, and finally, the supporting base plate is pulled out entirely, without any pulling on the cables. The installation process is the reverse: the supporting base plate is placed first, then the partitions are installed sequentially, with one cable laid for each partition layer installed. Finally, the cover plate assembly is replaced. The operation is simple and smooth, significantly improving construction and maintenance efficiency and reducing labor and time costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cable slack management device for low-voltage engineering is disclosed. The device consists of a support base plate 1, a detachable corrugated baffle assembly 2, a cover plate assembly 3, and fixing posts 4. The support base plate 1 is made of metal sheet by stamping, and the surface forms a continuous corrugated surface with alternating crests and troughs. Its radius of curvature R strictly follows the standard R≥8Dmax (Dmax is the maximum outer diameter of the cable). This design can ensure the safe radius when the cable is bent and avoid signal attenuation or insulation damage caused by excessive bending.

[0026] The detachable corrugated baffle assembly 2 consists of multiple sets of parallel ABS engineering plastic baffles 21. Each baffle 21 has a continuous corrugated surface, and its waveform curvature perfectly matches that of the supporting substrate 1. Each ABS engineering plastic baffle 21 includes a baffle body 211 and connecting ends 212 at both ends. The cross-sectional thickness of the connecting ends 212 is less than that of the baffle body 211 to accommodate the fixing grooves of the supporting substrate 1 and the cover assembly 3. The supporting substrate 1 has bottom fixing grooves 11, the same number as the baffles 21, with a shape consistent with the waveform of the baffles 21. The cross-sectional width of the grooves is less than the thickness of the baffle body 211 but greater than the thickness of the connecting ends 212, ensuring a secure and easy-to-remove connection for the baffles 21. The cover assembly 3 also has top fixing grooves 31, corresponding to the number of baffles 21, which cooperate with the bottom fixing grooves 11 to firmly fix the baffles 21. Together, these three components form a closed cable channel, effectively preventing dust, moisture, and interference with the cables from external forces.

[0027] The fixing piles 4 are respectively installed on the lower side of the crest and the upper side of the trough of the supporting base plate 1, and are connected to the supporting base plate 1 through the connecting stiffeners 41 to enhance the structural stability. The fixing post 42 at the bottom of the fixing pile 4 can be inserted into the bottom plate of the wiring trough to achieve stable installation of the device. Its bottom surface is flush with the bottom surface of the supporting base plate 1 in the assembled state. The upper part is provided with a connecting hole 43, which can cooperate with the upper fixing post 42 to realize the stacking installation of multiple layers of devices. The top surface of the fixing pile 4 is flush with the top surface of the cover plate assembly 3 in the assembled state to ensure the neatness and stability of the multi-layer structure.

[0028] In practical applications, the supporting base plate 1 is first fixed by inserting the fixing post 42 of the fixing stake 4 into the bottom plate of the wiring channel. Then, the connecting end 212 of the ABS engineering plastic partition 21 is sequentially inserted into the bottom fixing groove 11 of the supporting base plate 1. The wavy surface naturally forms multiple independent cable storage channels, realizing the classified arrangement of different types of cables and avoiding messy tangling. After the cables are arranged, the cover plate assembly 3 is closed, so that the top fixing groove 31 locks the connecting end 212 of the partition 21, forming a closed space. If it is necessary to inspect the lower layer cables, simply lift the cover plate assembly 3, remove the corresponding upper layer partition 21, release the cable slack, and the upper layer cables can be easily moved laterally without causing pulling damage to the cables. If multi-layer wiring is required, the fixing post 42 of the upper layer device can be inserted into the connecting hole 43 of the lower layer fixing stake 4, and the above installation steps can be repeated to achieve efficient utilization of vertical space.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
