Description

Technical Field

[0001] This application relates to the field of electronic and electrical equipment, and more specifically to a cable tray support for supporting cable trays, wherein the cable tray is used to arrange cables such as wires and signal lines. Background Technology

[0002] Cable trays are used in many fields for laying and supporting cables. Cable trays can hold cables such as power lines, signal lines, and fiber optic cables. Fixed to load-bearing structures such as walls, cable trays serve two purposes: firstly, they support long cables to prevent sagging and bending; secondly, they guide and organize cable routing. Applications of cable trays include, for example, supporting power and control cables in factories; organizing network and lighting cables in commercial buildings such as shopping malls; and guiding and carrying electrical and network cables in residential settings.

[0003] Cable tray supports are provided to secure cable trays to load-bearing structures such as walls. The cable tray supports are mounted to the wall using fasteners such as screws, and further secured to the cable trays using screws or similar fasteners.

[0004] The cable tray support frame currently in use is made of a single piece of metal sheet, in which two edges of the metal sheet are bent to form mounting flanges. One mounting flange is fitted to a load-bearing structure such as a wall and fixed to the wall by fasteners such as screws. The other mounting flange is used to fit with the cable tray to fix the cable tray in place.

[0005] For cable tray supports with this structure, their supporting strength depends on the strength of the metal sheet. To obtain the required strength, a thicker metal sheet must be used, which increases the manufacturing cost of the cable tray support. Moreover, when installing cable tray supports made of metal sheet, the plate-shaped cable tray body can also hinder the operation of installation tools, affecting the installation of the cable tray support.

[0006] Therefore, there is a need in this field to improve the structure of cable tray support frames, which can provide sufficient strength with a simple structure to support cable trays of various sizes and volumes, and are easy to install, while also having a lower manufacturing cost. Utility Model Content

[0007] This application is made to address the technical problems existing in the art as described above. The purpose of this application is to provide an improved cable tray support structure that provides sufficient strength to support structures such as cable trays, and significantly reduces their manufacturing costs. Furthermore, the structure of this cable tray support structure also allows for convenient installation.

[0008] This application provides a cable tray support frame, which includes a vertical mounting rod and a cantilever rod. One end of the cantilever rod is fixed to the vertical mounting rod, and the other end is a free end, thus the cantilever rod is in the form of a cantilever. At least one slot is formed in the cantilever rod, and a fixing fastener can be fitted into the slot to fix the cantilever rod to the structure supported by the cable tray support frame.

[0009] In the cable tray support frame described above, the cable tray support frame is installed by fixing it to a load-bearing structure such as a wall via vertical mounting rods. Slotted holes are formed on the cantilever rods, allowing for flexible selection of fixing positions for fasteners such as screws to adapt to the structure of the supported components, providing the required structural strength. This simple structure provides support for the supported components and facilitates installation. The connection between the cantilever rods and the vertical mounting rods can be achieved, for example, by welding.

[0010] Preferably, for applications supporting larger components, the cable tray support may further include support rods, one end of which is connected to a vertical mounting rod, and the other end to a cantilever rod, with the support rod forming acute angles with both the vertical mounting rod and the cantilever rod. Preferably, the connection point of the support rod to the cantilever rod is farther from the vertical mounting rod than from the free end of the cantilever rod. The support rod provides additional structural strength to the cable tray support, especially in applications with sizes such as 24-inch and 18-inch.

[0011] Preferably, a tool hole is formed on the support rod, the shape and size of which are configured to allow a tool to pass through and operate the fastener. In this way, the support rod does not obstruct the operation of the fasteners used to secure the cantilever rod, for example, to fix the component to be supported to the cantilever rod.

[0012] In a preferred embodiment, the cantilever bar includes two first sidewalls disposed opposite to each other and a first connecting wall connected between the two first sidewalls, such that the cross-section of the cantilever bar is U-shaped, wherein the first connecting wall is the top wall of the cantilever bar, and a slot is formed on the first connecting wall.

[0013] Alternatively, preferably, the vertical mounting rod is provided with at least two mounting holes, each of which is fitted with a mounting fastener.

[0014] At least one of the fixing fasteners and the mounting fasteners is a screw.

[0015] Furthermore, the mounting holes can be formed in the shape of a gourd. This gourd-shaped mounting hole helps improve fixing stability, thereby providing better fixing strength.

[0016] Similar to a cantilever bar, a support bar also includes two second sidewalls arranged opposite each other and a second connecting wall connecting the two second sidewalls, so that the cross-section of the support bar is U-shaped, wherein the second connecting wall is the bottom wall of the support bar, and a tool hole is formed on the second connecting wall.

[0017] Preferably, the fastener is a fixing screw, the screw head of which has a retaining plate, and at least one of the two sides of the retaining plate has a downwardly extending flange. This type of fixing screw facilitates the easy attachment of the component to the cantilever rod. Attached Figure Description

[0058] <First Embodiment>

[0059] Figure 1-6b A cable tray support 100 according to a first embodiment of this application is shown, which can be installed, for example, on a cable tray. Figure 1 A front view of a cable tray support 100 is shown, which has a vertical mounting rod 110 and is mounted on a load-bearing structure such as a wall via the vertical mounting rod 110.

[0060] Go to Figure 2The figure shows a top perspective view of a cable tray support 100, showing at least two mounting holes 111 formed on a vertical mounting rod 110. These mounting holes 111 engage with mounting fasteners, such as mounting screws 112 shown in the figure, which pass through the mounting holes 111 and are inserted into a wall to secure the vertical mounting rod 110 to the wall. In one embodiment, a threaded hole is formed in the wall, the internal thread of which matches the external thread of the mounting screw 112, allowing the mounting screw 112 to engage in the threaded hole. Alternatively, in an alternative embodiment, for example, where the wall serving as the load-bearing structure is thin, the mounting screw 112 passes through the wall from one side, while a nut is provided on the other side of the wall to engage with the mounting screw 112.

[0061] Preferably, as shown in the figure, the mounting hole 111 is formed in the shape of a gourd hole, which helps to ensure the fixing stability of the mounting screw 112 in the mounting hole 111, thereby providing better fixing strength.

[0062] In an alternative structure, the mounting hole 111 and the corresponding screw-nut structure can be omitted. For example, when the load-bearing structure is such as a metal panel or metal bracket, the vertical mounting rod 110 can be fixed to the load-bearing structure by means such as welding. Such cases are also within the scope of this application.

[0063] In addition to the mounting screw 112 shown in the figure, other types of fasteners, such as rivets, can be used for mounting fasteners that mate with the mounting hole 111.

[0064] The vertical mounting rod 110 can be made of cold-rolled steel (CRS), for example, 3.0 mm cold-rolled steel. This specification of cold-rolled steel provides the vertical mounting rod 110 with sufficient structural strength to securely mount the cable tray support 100 and to support other parts of the cable tray support 100, as described below, and components such as cable trays supported by the cable tray support 100.

[0065] The cable tray support frame 100 also includes a cantilever rod 120, one end of which is fixedly connected to the vertical mounting rod 110, for example, by welding. The other end of the cantilever rod 120 is a free end, thus the cantilever rod 120 is in the form of a cantilever. The cantilever rod 120 preferably extends substantially perpendicular to the vertical mounting rod 110.

[0066] like Figure 2As shown, in a preferred configuration, the cantilever rod 120 includes two first sidewalls 121 and a first connecting wall 122 extending between and connecting the two first sidewalls 121. Thus, the cross-section of the cantilever rod 120 is U-shaped, and the first connecting wall 122 serves as the top wall of the cantilever rod 120. This U-shaped cross-section provides additional structural strength to the cantilever rod 120. More preferably, the cantilever rod 120 is made of 2.0 mm cold-rolled steel.

[0067] At least one slot 123 is formed on the first connecting wall 122 of the cantilever rod 120. For example, in the structure shown in the figure, three slots 123 are provided. The slot 123 has a certain length so as to adapt to different installation occasions, such as adapting to the corresponding installation structure size of the fixed support component, such as the cable tray 10.

[0068] As can be clearly seen in Figure 3, fasteners, such as the fixing screw 140 shown in the figure, can be inserted into the slot hole 123 and used to secure components such as cable tray 10 to the cantilever rod 120 of the cable tray support frame 100. (See Figure 3 for details.) Figure 3b As seen in the enlarged view, the head of the fixing screw 140 is provided with a fixing piece 141, the two ends of which are respectively formed with flanges that extend downward and facilitate fixing, as will be described in detail below. Alternatively, the flange may be formed only on one side of the fixing piece 141, which is also within the scope of this application.

[0069] On the opposite side of the slot 123 opposite to the head of the fixing screw 140, a nut may be provided, the threads of which engage with the threads on the shank of the fixing screw 140 to achieve fixation.

[0070] In the case of large-sized cable tray support brackets 100, such as 24-inch or 18-inch sizes, the cable tray support bracket 100 also includes a support rod 130. This support rod 130 connects between the vertical mounting rod 110 and the cantilever rod 120, and forms an acute angle with both the vertical mounting rod 110 and the cantilever rod 120, thus forming a tripod shape for the cable tray support bracket 100 as a whole. Specifically, one end of the support rod 130 is connected to the vertical mounting rod 110, and the other end is connected to the cantilever rod 120 at a location closer to the free end of the cantilever rod 120 than to the vertical mounting rod 110.

[0071] Here, the dimensions of the cable tray support 100 are primarily based on the length of the cantilever rod 120, and this dimension corresponds to the width of the component to be supported, such as the cable tray 10. In the case of a large-sized cable tray support 100, the cantilever rod 120, due to its greater extension from the vertical mounting rod 110, tends to bend, and there will be significant stress at the connection between the cantilever rod 120 and the vertical mounting rod 110. By providing the support rod 130, the cantilever rod 120 can be supported, and some of the stress at the connection between the cantilever rod 120 and the vertical mounting rod 110 can be distributed, thereby improving the overall strength of the cable tray support 100.

[0072] Similar to the cantilever bar 120, the support bar 130 preferably includes two opposing second sidewalls 131 and a second connecting wall 132 extending between and connecting the two second sidewalls 131, thereby forming a generally U-shaped cross-section of the support bar 130. The second connecting wall 132 serves as the bottom wall of the support bar 130. Preferably, the support bar 130 may also be made of 2.0 mm cold-rolled steel.

[0073] Further preferably, at least one tool hole 133 is formed on the second connecting wall 132, which serves as the bottom wall of the support rod 130. This tool hole 133 may, for example, be in the form of a slot. Of course, the tool hole 133 may also be formed as a hole of other suitable size and shape, as long as it allows an operator to pass a tool through the tool hole 133 and extend it below the cantilever rod 120 to operate the fixing screw 140 to secure it. For example, a tool can be operated through the tool hole 133 to tighten a nut below the cantilever rod 120, engaging it with the fixing screw 140.

[0074] like Figure 5 , 6a As shown in Figure 6b, the component supported by the cable tray support frame 100 is exemplified by the cable tray 10. The cable tray 10 has a basket-like structure, consisting of multiple transverse strips 11 and longitudinal strips 12 extending substantially perpendicular to the transverse strips 11. The cantilever rods 120 of the cable tray support frame 100 extend substantially parallel to the longitudinal strips 12. Furthermore, depending on the spacing between adjacent transverse strips 11, two or more fixing screws 140 are provided, such as the two fixing screws 140 shown in the figure. These fixing screws 140 are inserted into corresponding slots 123 in the cantilever rods 120, and the flange of the fixing plate 141 on the head of the fixing screw 140 engages with the transverse strips 11. When the fixing screws 140 are tightened, the fixing plate 141 of the fixing screw 140 is fixed together with the transverse strips 11, thereby securing the cable tray 10 to the cantilever rods 120.

[0075] <Second Embodiment>

[0076] Figure 7-9b A cable tray support frame 200 according to a second embodiment of this application is shown. Unless otherwise described or conflicted, the specific structures described above with respect to the first embodiment also apply to the second embodiment. In the following description, identical structures will not be described in detail again; instead, structures that differ from those in the first embodiment will be specifically described.

[0077] In the second embodiment, the cable tray support frame 200 includes a vertical mounting rod 210 and a cantilever rod 220. At least two mounting holes 211 are formed on the vertical mounting rod 210, and mounting screws 212 can be fitted into the mounting holes 211 to achieve fixed installation of the cable tray support frame 200.

[0078] The cantilever rod 220 is fixedly connected to the vertical mounting rod 210 by means such as welding. The cantilever rod 220 is provided with at least one slot 223 for receiving the fixing screw 240.

[0079] Unlike the first embodiment, the cable tray support 200 of the second embodiment involves a smaller size, such as a 12-inch or 8-inch cable tray support 200. Therefore, the length of the cantilever rod 220 extending from the vertical mounting rod 210 in a cantilever form is smaller. Thus, in the cable tray support 200 of the second embodiment, the support rod structure is omitted.

[0080] The preferred embodiments of the cable tray support frame of this application have been described in detail above. Those skilled in the art can make various obvious variations and modifications based on the above disclosure, and these are still within the scope of this application.
