[0030] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0031] This utility model provides an improved cable tray that facilitates cable maintenance. The technical solution of this utility model is as follows:

[0032] like Figures 1-6As shown, a cable tray for easy cable maintenance includes a tray body 1 and multiple cover plates 2. The cover plates 2 are all hinged to one end of the tray body 1. Both the tray body 1 and the cover plates 2 have L-shaped cross-sections. Through this design, when the cover plates 2 are unfolded, [the following is an illustration / description of the cable tray design]. Figure 4 As shown in the diagram, compared to traditional U-shaped cable trays, this is a semi-open structure with a larger operating space, making it easier to inspect and maintain the internal cables; it also includes:

[0033] The locking assembly is used to engage the cover plate 2 with the cable tray body 1; the locking assembly secures the cover plate 2, placing it in a fixed position. Figure 1 - Figure 2 This configuration allows for better protection of the internal cables.

[0034] The follower assembly includes an arc-shaped rod 4 fixedly connected to the outer wall of the top of the cover plate 2. A connecting seat 901 is rotatably mounted at the end of the arc-shaped rod 4 via a movable shaft. A connecting slider 9 is fixedly connected to one side of the connecting seat 901. Figure 4 In this state, when the cover plate 2 is unfolded, the connecting seat 901 and the connecting slider 9 can be moved by using the arc rod 4.

[0035] The L-shaped slide block 8 has multiple pairs of limiting strips 7 fixedly installed on the inner bottom wall of the cable tray body 1. The L-shaped slide block 8 is slidably installed in the cable tray body 1 through the limiting strips 7. One side of the L-shaped slide block 8 is slidably connected to the connecting slider 9 in the vertical direction. With the above structure, when the arc rod 4 pushes the L-shaped slide block 8 to move, it can drive the cable on the L-shaped slide block 8 to move outward synchronously, which makes it easier to carry out maintenance.

[0036] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, in order to facilitate weight reduction and heat dissipation of cables, through holes 3 are provided on the main body 1 of the cable tray and multiple cover plates 2.

[0037] Furthermore, the arc-shaped rod 4 passes through the through hole 3 and extends into the interior of the main body 1 of the support bridge.

[0038] As a further embodiment of this utility model, such as Figures 4-6 As shown, a limiting end plate 801 is fixedly installed on the surface of each L-shaped slide 8; by means of the limiting end plate 801, the cable can be driven to move in the same direction when the L-shaped slide 8 moves.

[0039] As a further embodiment of this utility model, a set of V-shaped grooves 6 are provided at the positions of each pair of limiting strips 7 in the main body 1 of the cable tray.

[0040] Furthermore, each L-shaped slide block 8 has multiple recesses 10 at its bottom, and each recess 10 has a trapezoidal locking block 12 slidably installed inside it. Each trapezoidal locking block 12 is fixedly connected to a tension spring 11 between its top and the recess 10.

[0041] With the above structure, when the cover plate 2 is opened by manual force, the arc rod 4 can be used to push the L-shaped slide 8 to move. When the trapezoidal locking block 12 is aligned with the V-shaped groove 6, under the action of the tension spring 11, the trapezoidal locking block 12 can be inserted into the V-shaped groove 6 and form a locking effect. Thus, when the person releases their hand, the cover plate 2 can remain in this position and remain open, which facilitates maintenance. Conversely, when the cover plate 2 is closed by manual force, the arc rod 4 will pull the L-shaped slide 8 to reset, and during the reset process, it will overcome the resistance formed by the trapezoidal locking block 12 and the V-shaped groove 6.

[0042] Furthermore, the locking assembly includes multiple square slots 504 formed on the cover plate 2, and short shafts 502 are slidably installed in each square slot 504. A locking block 503, adapted to the square slot 504, is fixedly installed at the end of each short shaft 502. A horizontal plate 501 is fixedly installed at the end of each short shaft 502 away from the locking block 503. A pull rod 5 is fixedly installed on one side of the horizontal plate 501. A tension spring 505 is sleeved on each short shaft 502, and both ends of the tension spring 505 are fixedly connected to the cover plate 2 and the horizontal plate 501, respectively. With the above structure, when... Figure 5 - Figure 6 In the indicated state, the top of the locking block 503 abuts against the bottom of the cable tray body 1, thereby locking the cover plate 2. When it is necessary to open the cover plate 2, the pull rod 5 can be pulled to drive the horizontal plate 501 and the short shaft 502, so that the locking block 503 is engaged in the square slot 504. At this time, the engagement between the cover plate 2 and the cable tray body 1 can be released.

[0043] In any case, when it is necessary to close the cover plate 2, the pull rod 5 must be pulled first. After the cover plate 2 is closed, the pull rod 5 is released. At this time, under the action of the tension spring 505, the locking block 503 can extend to the bottom of the cable tray body 1 and form a snap-fit ​​relationship.

[0044] Furthermore, a sealing strip 201 is fixedly installed on both sides of each cover plate 2; the sealing strip 201 helps to improve the sealing performance of the cable tray body 1 when the cover plate 2 is closed.

[0045] The specific working method is as follows: During use, the pull rod 5 can be pulled, which drives the horizontal plate 501 and the short shaft 502, causing the locking block 503 to engage in the square slot 504. At this time, the locking relationship between the cover plate 2 and the cable tray body 1 can be released, and the cover plate 2 can be opened. After unfolding the cover plate 2, it will appear as follows:Figure 4 As shown in the diagram, compared to the traditional U-shaped cable tray, it is semi-open, with a larger operating space, making it easier to inspect and maintain the internal cables.

[0046] When the cover plate 2 is opened, the connecting seat 901 and the connecting slider 9 can be moved by the arc rod 4. When the arc rod 4 moves the L-shaped slide 8, the cable on the L-shaped slide 8 can move outward synchronously, which makes it easier to carry out maintenance.

[0047] When the cover plate 2 is opened manually, the arc rod 4 can push the L-shaped slide 8 to move. When the trapezoidal locking block 12 is aligned with the V-shaped groove 6, under the action of the tension spring 11, the trapezoidal locking block 12 can be inserted into the V-shaped groove 6 and form a locking effect. Thus, when the person releases their hand, the cover plate 2 can remain in this position and remain open, which facilitates maintenance. Conversely, when the cover plate 2 is closed manually, the arc rod 4 will pull the L-shaped slide 8 to reset, and during the reset process, it will overcome the resistance formed by the trapezoidal locking block 12 and the V-shaped groove 6.

[0048] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
