Description

Technical Field

[0001] This utility model belongs to the technical field of cable trays, specifically a cable tray connection locking structure. Background Technology

[0002] To connect multiple cable trays together for cable line protection, locking structures are typically installed between the trays for installation and fixation. Existing cable trays usually use bolts as locking structures to connect and fix the frame and cover together during installation. However, since cables are usually laid over long distances and multiple trays need to be connected, installers need to use a large number of bolts to connect and fix the trays. Installers need to prepare and carry a large number of bolts in advance, which puts a great burden on the installers. Moreover, the repeated bolt fixing operation requires continuous force, which is time-consuming, labor-intensive, inefficient, and has high labor costs. Even if there are other locking structures that do not use bolts, their structural designs are very complex, resulting in high production costs for cable trays and hindering large-scale production and use.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1-6 This utility model provides a cable tray connection locking structure, including a base plate 1, side plates 2 vertically arranged on both sides of the base plate 1, and a cover plate 3 parallel to the base plate 1. The two sides of the cover plate 3 are respectively connected to the sides of the two side plates 2 that are relatively far away from the base plate 1. The two ends of the side plates 2, the base plate 1, and the cover plate 3 respectively form a first opening 41 and a second opening 42 that are connected. The length and width of the first opening 41 are smaller than the length and width of the second opening 42, that is, the plate spacing at the first opening 41 is smaller than the plate spacing at the second opening 42. A slider 21 is provided on the side wall of the side plate 2 near the first opening 41. A groove 22 for cooperating with the slider 21 is provided on the side wall of the side plate 2 near the second opening 42. The groove 22 includes a horizontal slide 221 extending from the second opening 42 toward the first opening 41 and a vertical slide 222 extending downward relative to the horizontal slide 221. One end of the horizontal slide 221 is connected to the second opening 42, and the other end is connected to the vertical slide 222.

[0029] During installation, the slider 21 on the first opening 41 of one cable tray aligns with the slide rail on the second opening 42 of the other cable tray. One end of the first opening 41 is then inserted into one end of the second opening 42, causing the slider 21 to move along the horizontal slide rail 221 towards the vertical slide rail 222. Once the slider 21 reaches the junction of the horizontal and vertical slide rails 222, it continues to move until it is fully inserted into one end of the vertical slide rail 222. Under the weight of the cable tray itself or with the pressure applied by the installer, the slider 21 located at one end of the cable tray moves downwards along the vertical slide rail 222. At the bottom, the slider 21 is fixed and limited at the bottom of the vertical slide rail 222. The two bridge frames are thus securely connected through the limiting connection between the slider 21 and the slide rail. Because the slider 21 is firmly connected to the slide rail 22 in the lateral direction, it effectively prevents the connection between the two frames from loosening due to vibration or other factors, achieving a highly efficient and high-quality connection and fixation. This invention, by setting a locking structure between the slider 21 and the slide rail 22, allows installers to simply align and push the slider 21 into the side opening of the slide rail 22 and press it down to complete the connection and fixation operation. Installation is convenient, time-saving, labor-saving, and reduces labor costs.

[0030] The overall structure of this utility model is simple. The slider 21 and the slide rail expansion are integrally stamped on the side plate 2. The production process is simple and easy to process. The production cost is not much different from the original overall frame production, which is conducive to large-scale production and use.

[0031] In some embodiments, the slider 21 and the slide rail are disposed on the outer surfaces of different sides of the side plate 2. Specifically, the slider 21 is protruding from the outer wall of the side plate 2 facing outwards, and the slide rail is opened on the inner wall of the side plate 2 facing inwards. When one end of a cable tray corresponding to the first opening 41 is inserted into one end of another cable tray corresponding to the second opening 42, the slider 21 moves along the inner wall of the side plate 2 as the insertion moves, thereby contacting the slide rail opened on the inner wall, and thus the slider 21 can move in close contact within the slide rail.

[0032] In some embodiments, the slider 21 and the slide rail can be disposed on the same side of the side plate 2. Specifically, the slider 21 and the slide rail are both protruding from the outer wall of the side plate 2 facing outwards. In order to avoid the slide rail on the inner wall causing the overall wall thickness of the side plate 2 to be too large and affecting the cable assembly space inside the cable tray, and in order to reduce the weight of the cable tray and save materials, in this embodiment, the slider 21 and the groove at both ends of the side plate 2 are integrally stamped on the side plate 2 sheet, and the stamping and recessing directions are opposite, thereby avoiding the adverse effects of the overall volume of the cable tray being too large, the production cost being too high, and the excessive compression of the installation space.

[0033] In some embodiments, the slider 21 and the slide rail are provided with multiple sets at both ends of the side plate 2 (see reference). Figure 5 and Figure 6 The corresponding connection and fixation of multiple sets of sliders 21 and slide grooves 22 can further enhance the connection stability between the two connected bridge frames.

[0034] In some embodiments, guide ramps 23 are provided on the horizontal slides 221 on the two side plates 2 near the second opening 42. The distance between the two guide ramps 23 gradually decreases from the second opening 42 toward the vertical slide 222. The minimum distance between the two guide ramps 23 is equal to the width of the slide groove 22. The guide ramps 23 can guide the insertion action during installation and avoid jamming that affects the installation efficiency.

[0035] In some embodiments, an arc-shaped connecting portion 24 is provided at the connection between the vertical slide and the horizontal slide 221 of the slide groove 22. So after the slider 21 moves completely from the horizontal slide 221 to one end of the vertical slide 222, the slider 21 can slide downward along the arc-shaped connecting portion 24 at one end of the vertical slide 222 under the action of gravity, thereby avoiding jamming when the slide groove 22 transitions from the horizontal slide 221 to the vertical slide 222, and improving installation efficiency.

[0036] In some embodiments, the cover plate 3 is detachably mounted on the side plate 2. Two opposing bent hooks 31 extend downwards from both sides of the cover plate 3 corresponding to the two sides of the side plate 2. The outer walls of both sides of the side plate 2 are provided with slots 25 for engaging the hooks 31 (see reference). Figure 2 and Figure 6 During installation, after aligning the hook 31 with the slot 25, slide the cover plate 3 from one end of the side plate 2 until it is completely covered, so that the fixed connection of the cover plate 3 is stable and not easy to loosen.

[0037] In some embodiments, the side plate 2 is provided with a plurality of heat dissipation holes 26 in an array that connect the inner wall and the outer wall, so that the heat generated by the cable placed on the base plate 1 during operation can be dissipated outward through the heat dissipation holes 26, avoiding adverse effects such as the cable insulation layer melting due to excessively high internal temperature of the cable tray.

[0038] In some embodiments, the base plate 1, side plate 2, and cover plate 3 are all made of aluminum alloy, which has good corrosion resistance and a long service life.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application shall fall within the scope of the technical solution of this application.
