A cable management device for low-voltage electrical engineering

Abstract

This utility model provides a cable management device for low-voltage engineering cable trays, belonging to the technical field of cable management devices. It includes a cable tray body, a top cover, a U-shaped frame, an inner cavity partition cover plate, and a connecting structure. The bottom surface of the top cover, which is slidably disposed on the upper end of the cable tray body, is fixed to the inner cavity partition cover plate via the connecting structure. The inner cavity partition cover plate is correspondingly fixed along the length direction to the U-shaped frame on the bottom surface of the inner cavity of the cable tray. As the top cover slides, the inner cavity partition cover plate slides out from the corresponding U-shaped frame. The inner cavity partition cover plate divides the inner cavity of the U-shaped frame into individual chambers for single cables to pass through, preventing cables from tangling. When a new signal is added and a spare core of a cable is needed, or when searching for a specific cable for inspection and maintenance, the corresponding cable can be found more quickly.

Description

Technical Field

[0001] This utility model relates to the field of cable management devices, and in particular to a cable management device for low-voltage engineering cable trays. Background Technology

[0002] The descriptions in this section provide background information relating to this disclosure and do not constitute prior art.

[0003] Low-voltage electrical engineering typically refers to the engineering field that uses electrical systems and equipment with low voltage and low current, mainly involving communications, security, and automation control. Control cabinets are common equipment in low-voltage electrical engineering. Currently, the number of cables inside control cabinets is enormous, making cable management complex. The crisscrossing and tangling of cables not only affects the effective use of space but also increases the difficulty of maintenance and repair.

[0004] Control cabinets typically include cable trays as components for securing and organizing cables. Their main function is to keep cables neat and orderly, ensuring they do not interfere with each other, and facilitating maintenance and repair. However, cable trays also present some problems during use. When there are a large number of cables in the cable tray, tangling can occur. When a new signal is added and a spare core of a cable is needed, or when searching for a specific cable for maintenance, a significant amount of time is wasted, reducing the efficiency of maintenance personnel. Utility Model Content

[0021] The bottom surface of the top cover has reserved screw holes corresponding to the fixing bolts;

[0022] The upper end of the fixing bolt is screwed into the corresponding reserved screw hole.

[0023] As a further optimization, to store cables separately in multiple storage cavities, with each cavity holding only one cable, thus preventing cables from becoming tangled and allowing for faster retrieval of the required cable, the inner cavity partition cover includes:

[0025] A first partition plate is fixedly assembled on the bottom surface of the first cover plate along the length direction, and the first partition plate is parallel to the length direction of the running groove.

[0026] The lower end of the first partition plate abuts against the bottom surface of the inner cavity of the U-shaped frame;

[0027] The first storage cavity is formed at the position between adjacent first partitions and at the position between the outer first partition and the inner wall of the U-shaped frame on the same side.

[0028] As a further optimization, to store cables separately in multiple storage cavities, with each cavity holding only one cable, thus preventing cables from becoming tangled and allowing for faster retrieval of the required cable, the inner cavity partition cover includes:

[0029] The second cover plate is fastened to the upper end of the U-shaped frame;

[0030] The bottom surface of the second cover plate is fixedly fitted with a grid frame, the opening direction of which is the same as the length direction of the running groove;

[0036] The hexagonal through-hole forms a third receiving cavity.

[0037] As a further optimization, in order to store cables separately through multiple storage cavities, with each storage cavity holding only one cable, to avoid the cables from getting tangled and messy in the storage cavities and to find the required cable more quickly, the hexagonal through hole of the inner cavity partition cover is replaced with a circular through hole.

[0038] The circular through-hole forms a fourth storage cavity.

[0039] As a further optimization, in order to mark each storage cavity and determine the corresponding information of the stored cables in each storage cavity, labels are attached and fixed to the corresponding chambers separated by the inner cavity partition cover.

This inner cavity partition cover plate is fixed to the U-shaped frame on the bottom surface of the inner cavity of the cable tray along its length. As the top cover slides, the inner cavity partition cover plate slides out from the corresponding U-shaped frame. The inner cavity partition cover plate divides the inner cavity of the U-shaped frame into individual chambers for single cables to pass through, preventing cables from tangling together. This allows for faster locating of the corresponding cable when a new signal is added and a spare core of a cable is needed, or when a specific cable is being located for inspection and maintenance.

[0055] Example 1, please refer to Figures 1, 2, 6, 7 and 8. The present invention provides a technical solution: a cable tray device for low-voltage engineering, including a cable tray body 1, with a top cover 2 slidably mounted on its upper end;

[0056] A U-shaped frame 3 is fixedly assembled on the bottom surface of the inner cavity of the line groove 1 along the length direction, and its opening direction is the same as the length direction of the line groove 1;

[0057] The inner cavity partition cover plate 4 is fastened to the upper end of the U-shaped frame 3;

[0058] The inner cavity partition cover plate 4 has a lower end partition U-shaped frame 3 for the inner cavity;

[0059] A connecting structure 6 is assembled between the top surface of the inner cavity partition cover plate 4 and the bottom surface of the top cover 2.

[0060] Specifically, in this embodiment, the top cover 2 is made of iron, and the U-shaped frame 3 is a right-angled U-shaped frame;

[0061] Furthermore, the bottom surface of the top cover 2, which is slidably disposed on the upper end of the cable tray 1, is fixed with an inner cavity partition cover plate 4 by a connecting structure 6. The inner cavity partition cover plate 4 is fixed to the U-shaped frame 3 on the bottom surface of the inner cavity of the cable tray 1 along the length direction. As the top cover 2 slides, the inner cavity partition cover plate 4 slides out from the corresponding U-shaped frame 3. This design allows cables to be inserted into each cavity of the inner cavity partition cover plate 4 first, and then the inner cavity partition cover plate 4 is driven into the corresponding U-shaped frame 3 by the sliding of the top cover 2, which facilitates the assembly of cables.

[0062] More specifically, the inner cavity partition cover 4 divides the inner cavity of the U-shaped frame 3 into individual chambers for passing through a single cable, avoiding the cables from getting tangled together. When a new signal is added and a spare core of a cable is needed, or when a specific cable is being searched for during inspection and maintenance, the corresponding cable can be found more quickly.

[0063] It is understandable that the device is used to install cable trays inside, and the cable trays contain a large number of low-voltage equipment. The cable tray body 1 and the top cover 2 are similar to existing cable trays, and a cable management device is installed inside the cable tray.

[0064] The U-shaped frame and the corresponding inner cavity partition cover are distributed at equal intervals along the length of the cable tray. The distance between adjacent inner cavity partition covers is less than 10 centimeters. The cables are segmented and organized, and space is provided for the cables to pass through the gaps in the outer wall of the cable tray to connect, avoiding cable tangling caused by the lack of cable management structure over long distances.

[0065] In this embodiment, the top surface of the inner cavity partition cover plate 4 and the top cover 2 can be connected in various ways, and these connection methods can be selected as needed;

[0066] like Figure 6 As shown, connection structure 6 includes:

[0067] The first circular groove 61a is formed on the top surface of the inner cavity partition cover plate 4;

[0068] A magnetic sheet 62a is pasted and fixed inside the first circular groove 61a, and is magnetically attracted and fixed to the bottom surface of the top cover 2.

[0069] The inner cavity partition cover 4 is magnetically fixed to the bottom surface of the iron top cover 2 by magnetic adsorption using magnetic sheet 62a. This connection method makes disassembly convenient and leaves no glue residue.

[0070] like Figure 7 As shown, the connecting structure 6 includes: a second circular groove 61b, which is formed on the top surface of the inner cavity partition cover plate 4;

[0071] A double-sided adhesive layer 62b is pasted and fixed inside the second circular groove 61b, and its top surface is pasted and fixed to the bottom surface of the top cover 2;

[0072] The second circular groove 61b is used to attach and fix the double-sided adhesive layer 62b. The other side of the double-sided adhesive layer 62b is attached and fixed to the bottom surface of the top cover 2. The double-sided adhesive layer 62b can be peeled off and replaced to ensure its adhesion, and disassembly is relatively convenient.

[0073] like Figure 8 As shown, the connection structure 6 includes: a mounting through hole 61c, which is opened on the top surface of the inner cavity partition cover plate 4;

[0074] A fixing bolt 62c passes through the lower end of the mounting through hole 61c;

[0075] The bottom surface of the top cover 2 has reserved screw holes for the corresponding fixing bolts 62c;

[0076] The upper end of the fixing bolt 62c is screwed into the corresponding reserved screw hole;

[0077] The top cover 2 and the inner cavity partition cover 4 are fixedly connected by bolts 62c, which are screwed into the reserved screw holes on the bottom surface of the top cover 2 through the mounting through hole 61c. The installation and removal of the fixing bolts 62c require a screwdriver, and the assembly is relatively convenient.

[0078] Immediately, when using bolted or adhesive connections, the top cover 2 does not need to be made of iron; it can be made of other materials such as aluminum alloy or PVC board.

[0079] In some embodiments, the inner cavity partition cover 4 includes:

[0080] The first cover plate 41a is fastened to the upper end of the U-shaped frame 3;

[0081] A first partition plate 42a is fixedly assembled on the bottom surface of the first cover plate 41a along the length direction, and the first partition plate 42a is parallel to the length direction of the running groove 1;

[0082] The lower end of the first partition 42a abuts against the bottom surface of the inner cavity of the U-shaped frame 3;

[0083] The first storage cavity 43a is formed between adjacent first partitions 42a and between the outer first partition 42a and the inner wall of the U-shaped frame 3 on the same side.

[0084] Specifically in this embodiment, the space between the U-shaped frame 3 and the first cover plate 41a is divided into independent first storage cavities 43a by multiple first partitions 42a, and only one cable can pass through each first storage cavity 43a;

[0085] Furthermore, the number of first partitions 42a can be set as needed, but it is necessary to ensure that the width of the first storage cavity 43a is greater than the outer diameter of the cable;

[0086] More specifically, the first storage cavity 43a formed by this partitioning method has a lot of remaining space in the height direction, and the space is not fully utilized, so the number of cables that can be stored individually is small.

[0087] In some embodiments, labels 5 are attached and fixed to the chambers separated by the inner cavity partition cover 4.

[0088] Specifically, in this embodiment, label paper 5 is pasted and fixed on the inner wall edges of the first storage cavity 43a and the second storage cavity 43b;

[0089] Labels 5 are affixed and fixed to the edges of the third storage cavity 44c and the fourth storage cavity 42d;

[0090] Furthermore, the label paper 5 is used to print or write cable information. One label paper 5 is set for each cable, and a specific cable can be found more quickly by viewing the label paper 5.

[0091] Example 2, please refer to Figure 3, differs from Example 1 in that:

[0092] The inner cavity partition cover plate 4 includes:

[0093] The second cover plate 41b is fastened to the upper end of the U-shaped frame 3;

[0094] The bottom surface of the second cover plate 41b is fixedly fitted with a grid frame 42b, the opening direction of which is the same as the length direction of the running groove 1;

[0095] A second storage cavity 43b is formed between the grid frame 42b, the inner wall of the U-shaped frame 3, and the bottom surface of the second cover plate 41b.

[0096] Specifically in this embodiment, the grid frame 42b divides the space between the U-shaped frame 3 and the second cover plate 41b into independent second storage cavities 43b, and only one cable can pass through each second storage cavity 43b;

[0097] Furthermore, the number of second storage cavities 43b can be set as needed, but it is necessary to ensure that the width of the second storage cavity 43b is greater than the outer diameter of the cable;

[0098] More specifically, the first storage cavity 43a formed by this partitioning method is also divided in the height direction, making better use of space and being able to store more cables compared to Embodiment 1.

[0099] Example 3, please refer to Figure 4, differs from Example 1 in that:

[0100] The inner cavity partition cover plate 4 includes:

[0101] The third cover plate 41c is fastened to the upper end of the U-shaped frame 3;

[0102] The bottom surface of the third cover plate 41c is fixedly fitted with a second partition plate 42c, which is perpendicular to the length direction of the running groove 1;

[0103] The second partition plate 42c has hexagonal through holes 43c evenly opened along the length of the groove 1 on its side wall, and the inner corners of its inner wall are rounded.

[0104] The hexagonal through-hole 43c forms a third receiving cavity 44c.

[0105] Specifically in this embodiment, the second partition 42c is perpendicular to the length direction of the cable tray 1 and blocks the cable threading direction in the cable tray 1. The cable is threaded through the hexagonal through hole 43c opened on it. Only one cable can pass through one hexagonal through hole 43c.

[0106] Furthermore, the inner corners of the hexagonal through-hole 43c are rounded to avoid wear on the outer wall of the cable. The hexagonal through-hole 43c can achieve a higher aperture ratio through its own characteristics.

[0107] More specifically, the third storage cavity 44c formed by the inner cavity of the hexagonal through hole 43c can be set as needed, but it is necessary to ensure that the width of the third storage cavity 44c is greater than the outer diameter of the cable, and that adjacent third storage cavities 44c are not connected.

[0108] Understandably, this hexagonal through-hole 43c is used for cable threading, and its high aperture ratio design allows it to accommodate more cables.

[0109] Example 4, please refer to Figure 5, differs from Example 3 in that:

[0110] The hexagonal through hole 43c of the inner cavity partition cover plate 4 is replaced with a circular through hole 41d;

[0111] The circular through hole 41d forms a fourth receiving cavity 42d within it.

[0112] Immediately, the hexagonal through-hole 43c can be replaced with a circular through-hole 41d, simplifying the through-hole opening process.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
