Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable tray technology, and specifically to a cable tray that is easy to assemble. Background Technology
[0002] Cable trays are frequently used in electrical engineering construction, and they come in various structures such as trough type, tray type, ladder type, and mesh type. Cable trays within buildings can be installed independently or attached to various building and pipe rack supports. They should be characterized by simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance.
[0003] For example, Chinese Patent Application No. 2023214746178 discloses a cable tray that is easy to assemble. It includes a first cable tray, a second cable tray that is inserted into the inner cavity of one end of the first cable tray, and fixing blocks are provided on both sides of the first cable tray near the second cable tray. Locking components are inserted into both sides of the front of the fixing blocks. The locking components include locking rods. One end of one locking rod is inserted into the connection between the first cable tray and the second cable tray, and one end of the other locking rod is inserted into the groove wall of the second cable tray. This device only requires the two cable trays to be aligned end to end, and the locking components lock directly, reducing the time for assembling the cable trays. However, it cannot adjust the length of the cable trays in a timely manner according to the actual situation.
[0004] Based on the above solutions, traditional cable trays require the selection of appropriate cable tray specifications during installation, and the length of the tray cannot be adjusted in a timely manner according to the actual situation; moreover, the elbow connection structure is fixed, and its length and curvature cannot be adjusted according to the actual situation. Existing straight cable trays and elbows need to be perfectly matched during assembly. If there is an error, the entire cable tray needs to be adjusted, resulting in low construction efficiency.

[0029] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0030] An embodiment of a cable tray that is easy to assemble provided by this utility model:
[0031] like Figures 1 to 6 As shown, the cable tray assembly includes a cable tray assembly 1, one end of which is provided with an elbow connection assembly 2. The cable tray assembly 1 includes a cable tray body 101, and an adjustment frame 102 is provided below the cable tray body 101.
[0032] like Figure 3 , Figure 4 As shown, a limiting groove 1012 is provided at the position where the cable tray body 101 connects with the adjusting frame 102. A strip groove 1021 is provided on the surface of the adjusting frame 102. A fixing bolt 1022 is provided inside the strip groove 1021. A fixing hole that matches the fixing bolt 1022 is provided at one end of the cable tray body 101. The adjusting frame 102 is slidably connected to the cable tray body 101 through the limiting groove and fixed by the fixing bolt 1022.
[0033] A mounting plate 103 is provided at one end of the cable tray body 101. Multiple mounting holes 1011 are provided at both ends of the cable tray body 101. The surface of the mounting plate 103 is provided with round holes that are compatible with the mounting holes 1011. The cable tray body 101 is quickly spliced with other cable tray bodies by engaging with bolts through the mounting holes 1011.
[0034] like Figure 5 , Figure 6 As shown, the elbow connection assembly 2 includes an arc plate 201, which is disposed at one end of the cable tray body 101. Both sides of the arc plate 201 are provided with curved expansion joints 203. The curved expansion joint 203 includes two scissor-type expansion frames 2031. A roller 2032 and a support cylinder 2033 are disposed between the two scissor-type expansion frames 2031, and the support cylinder 2033 is located below the roller 2032.
[0035] One end of the scissor-type telescopic frame 2031 is provided with a fixed seat 2034. The fixed seat 2034 is movably connected to the hinge position of the two scissor-type telescopic frames 2031. The fixed seat 2034 is provided on the surface of the adjusting frame 102. A limit pin 202 is provided above the arc plate 201. Multiple slots that are adapted to the limit pin 202 are opened on both sides of the arc plate 201.
[0036] like Figure 3 As shown, the end of the adjustment frame 102 away from the cable tray body 101 is provided with a fixing slot 1023 that is adapted to the arc plate 201, for docking with the arc plate 201 of the elbow connection assembly 2.
[0037] Traditional cable trays require selecting appropriate cable tray specifications during installation, making it impossible to adjust the tray length promptly according to actual conditions. Furthermore, the fixed connection structure of elbows prevents length and curvature adjustments. Existing straight-through cable trays require perfect matching with elbows during assembly; any discrepancies necessitate adjustments to the entire cable tray system, leading to low construction efficiency. To address this issue, the following measures are taken:
[0038] When connecting two fixed cable tray bodies 101, they need to be connected using the elbow connection assembly 2. First, the adjusting brackets 102 on the two cable tray bodies 101 are pulled out to a preset length, that is, the adjusting brackets 102 are manually pulled out from one end of the cable tray body 101. The adjusting brackets 102 slide along the limiting grooves 1012 on the cable tray body 101. The structural design of the limiting grooves 1012 can prevent the adjusting brackets 102 from falling off the cable tray body 101. Then, the arc plate 201 in the elbow connection assembly 2 is aligned with the fixing slots 1023 on the adjusting brackets 102 and pressed to fix them. The two ends of the arc plate 201 are respectively locked onto the two adjusting brackets 102. Then, the fixing seat 2034 at one end of one of the curved expansion joints 203 is fixed to the adjusting bracket 102 with bolts. At the same time, the fixing bolts 1022 pass through the strip grooves 1021. The fixing hole extends into the interior of the cable tray body 101, thereby fixing the extension length of the adjusting bracket 102. Then, pull the fixing seat 2034 at the other end of the curved expansion member 203 to align with the installation position of the adjusting bracket 102 on the other cable tray body 101. During this process, the scissor-type expansion bracket 2031 on the curved expansion member 203 deforms accordingly, thereby manually adjusting the curvature of the curved expansion member 203. Using the curvature of the arc plate 201 as a reference, it is adjusted appropriately. By observing the curvature of the curved expansion member 203 at this time, the limiting pin 202 is inserted into the corresponding insertion hole on the arc plate 201, that is, the limiting pin 202 is located in the bending direction of the curved expansion member 203, thereby initially limiting the curvature of the curved expansion member 203. Similarly, the curved expansion member 203 on the other side of the arc plate 201 is installed.
[0039] Finally, the fixing bolt 1022 passes through the strip groove 1021 and the fixing hole and extends into the interior of another cable tray body 101, so that the extension length of the adjustment bracket 102 remains unchanged, avoiding deformation of the adjusted bend expansion member 203, and solving the shortcomings of traditional cable trays in length adjustment and bend connection.
[0040] It is worth noting that when pulling cables through bends, the cables are prone to wear and tear, resulting in greater resistance. To solve this problem, the cable can be placed above the roller 2032 in the bend expansion joint 203. Then, a cable tie is passed through the scissor-type telescopic frame 2031 in the bend expansion joint 203 and wrapped around the cable to form a loop. At this time, the cable tie does not fix the cable. The cable on the bend expansion joint 203 can be fixedly tied. Then, the cable is pulled so that it is transmitted on the roller 2032 at a certain arc, avoiding the cable from colliding and bending on traditional bends and causing wear and tear on the cable, thus reducing resistance.
[0041] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.
[0042] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
