[0002] As a key load-bearing structure in power, communication, and building wiring systems, the installation convenience and path adaptability of cable trays directly affect the project efficiency and later maintenance costs. Although traditional tray systems can achieve angular connection through prefabricated elbows, tees and other components, limited by the fixed design, the following technical drawbacks still exist in complex wiring scenarios: 1. The elbows, tees and other connectors of traditional trays usually have fixed angles and need to be customized in advance according to the design drawings. When the on-site cable path changes due to building structure deviation or temporary adjustment requirements, the fixed-angle components cannot be flexibly adapted, and it is necessary to re-customize or cut and transform on-site, resulting in project delays and material waste; 2. Secondly, when the number of cables increases or the cable diameter changes, the existing trays cannot flexibly adjust the cross-sectional size, and it is necessary to replace the whole or stack new trays, resulting in resource waste and increased installation complexity.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 12 , the present invention provides a technical solution: an adjustable cable tray, which includes the splicing of two or more unit tray components. The unit tray component includes: The first bottom plate 2 and the second bottom plate 3 that overlap each other are used for bottom supporting the cables. The rear vertical plate 1 and the front vertical plate 4 are sequentially arranged at the opposite ends of the first bottom plate 2 and the second bottom plate 3; the first bottom plate 2 is driven by a transverse driving component and slides linearly along the Z-axis relative to the second bottom plate 3, and the distance between the rear vertical plate 1 and the front vertical plate 4 is adjusted to meet the requirements of different widths of cable assemblies; the transverse driving component includes a transverse adjusting handle 23, a lead screw nut 24 and a transverse lead screw 25. The lead screw nut 24 is fixedly arranged on the side wall of the first bottom plate 2, and a cylindrical cavity for accommodating the transverse lead screw 25 is opened on the first bottom plate 2; one end of the transverse lead screw 25 is fixedly connected to the transverse adjusting handle 23, and the other end of the transverse lead screw 25 sequentially penetrates through the front vertical plate 4, the second bottom plate 3 and the lead screw nut 24 and extends into the cylindrical cavity. Further, by rotating the transverse adjusting handle 23, it drives the transverse lead screw 25 to rotate. Under the screwing action of the internal and external threads, the lead screw nut 24 drives the first bottom plate 2 to slide on the second bottom plate 3, achieving the function of adjusting the distance between the front vertical plate 4 and the rear vertical plate 1, so as to be applicable to the laying requirements of different numbers of cables.

[0034] As shown Figure 2 and Figure 3 shown, the upper baffle 5 is fixedly lapped on the rear vertical plate 1 and the front vertical plate 4 through a detachable structure; the upper baffle 5 is disposed opposite to the first bottom plate 2 and the second bottom plate 3, and the upper baffle 5 is formed by splicing two groups of L-shaped beam plates, and can be expanded or closed as the distance between the rear vertical plate 1 and the front vertical plate 4 changes.

[0035] As shown Figure 4 , Figure 10 and Figure 12 shown, left adjusting plates 6 and right adjusting plates 8 are fixedly arranged on both the rear vertical plate 1 and the front vertical plate 4. The left adjusting plate 6 is rotationally matched with the right adjusting plate 8 and locked by an axial tightening assembly; the up-and-down rotation ranges of both the left adjusting plate 6 and the right adjusting plate 8 are 0-90°; the axial tightening assembly includes a fixed screw 7 and a first adjusting sleeve 9; the fixed screw 7 is fixedly arranged on the left adjusting plate 6, a round hole for accommodating the fixed screw 7 is formed on the right adjusting plate 8, and the first adjusting sleeve 9 is screwed onto the fixed screw 7 and abuts against the right adjusting plate 8.

[0036] Furthermore, by arranging the fixed screw 7, the first adjusting sleeve 9 to cooperate with the left adjusting plate 6 and the right adjusting plate 8, the angle of adjacent unit bridge components can be rotated and adjusted up and down by 0-90°, which can bypass obstacles such as pipelines and equipment, adapt to complex building structures or temporary path change requirements, and achieve the effect of following the shape for wiring.

[0037] As shown Figures 10 - 12 shown, a cable clamping component is arranged on the left adjusting plate 6, and the cable tension is adjusted adaptively according to the angle changes of the left adjusting plate 6 and the right adjusting plate 8; the cable clamping component includes a longitudinal movable seat 10, an adjusting pressure rod 11, a support rod 12, a moving frame 30 and a cylindrical slider 31. The longitudinal movable seat 10 moves up and down on the left adjusting plate 6; the adjusting pressure rod 11 is slidably installed on the longitudinal movable seat 10 and locked by a limiting component; the moving frame 30 is limit slidably installed in the left adjusting plate 6 and fixedly connected with the longitudinal movable seat 10; the cylindrical slider 31 is eccentrically arranged on the side wall of the right adjusting plate 8, an arc groove of 180° is formed on the side wall of the left adjusting plate 6, and the cylindrical slider 31 penetrates through the arc groove and is movably inserted into the moving frame 30.

[0038] Furthermore, by setting the adjusting lever 11 and the support rod 12 to cooperate with each other, part of the cable can be jacked up to be distributed in a parabolic shape, providing a reserved length for the tension adjustment; and by the combined use of the moving frame 30 and the cylindrical slider 31, the longitudinal movable seat 10 can move up and down adaptively with the angle change of the right adjusting plate 8. The longitudinal movable seat 10 acts on the adjusting lever 11 and the support rod 12 together, so that while the bridge assembly is adjusted in angle, the cable at the left adjusting plate 6 can adaptively give length compensation, thus avoiding the cable being in a tight state, ensuring the integrity of its physical structure, and extending the service life of the cable.

[0039] As Figure 12 shown, the limiting component includes a clamping block 29, a Z-axis screw 28 and a second adjusting nut 27. The clamping block 29 moves up and down in the longitudinal movable seat 10; one end of the Z-axis screw 28 is fixedly connected to the clamping block 29, and the other end of the Z-axis screw 28 is rotatably connected to the adjusting lever 11; the second adjusting nut 27 is sleeved on the Z-axis screw 28 and abuts against the side wall of the longitudinal movable seat 10. The support rod 12 and the adjusting lever 11 are arranged oppositely and are rotatably installed on the longitudinal movable seat 10 in a limited way.

[0040] Specifically, by screwing the second adjusting nut 27 closer to or away from the Z-axis screw 28, the longitudinal movable seat 10 is tightened or loosened, so as to facilitate the up and down adjustment of the adjusting lever 11 and quickly fix the adjusted adjusting lever 11 on the longitudinal movable seat 10 in time.

[0041] As Figure 8 and Figure 9 shown, a connecting bar 13 is provided on the rear vertical plate 1, and an upper limiting rod 14 is arranged on the connecting bar 13. The connecting bar 13 is driven by a longitudinal driving component to move up and down, and the height of the upper limiting rod 14 is adjusted to meet the assembly requirements of cables with different diameters. The longitudinal driving component includes a linkage seat 17, a longitudinal driving screw 18, a longitudinal adjusting handle 1801 and a wedge block 21. The connecting bar 13 is rotatably installed on the linkage seat 17 in a limited way; a narrow groove is also opened on the side wall of the linkage seat 17, and the wedge block 21 extends into the narrow groove and is connected to an elastic component; the elastic component is a second spring 22; the lower end of the wedge block 21 is a horizontal part, which can limit the upper end of the connecting bar 13, so that the connecting bar 13 can stably move up and down with the linkage seat 17. The linkage seat 17 is slidably installed on the rear vertical plate 1 in a limited way, and an internal thread hole is opened in the middle of the linkage seat 17; one end of the longitudinal driving screw 18 is fixedly connected to the longitudinal adjusting handle 1801, and the other end of the longitudinal driving screw 18 extends from the bottom of the rear vertical plate 1 and is inserted into the internal thread hole.

[0042] Furthermore, by setting the longitudinal drive screw 18, the longitudinal adjustment handle 1801 and the linkage seat 17 to cooperate with each other, the connection bar 13 can be driven to move up and down, so that the height of the upper limit rod 14 can be adjusted according to the change in the diameter of the cable to be assembled.

[0043] As Figure 5 and Figure 9 shown, a central shaft is fixedly inserted at the end of the connection bar 13, a spur gear 15 is fixedly sleeved on the central shaft, and the spur gear 15 is meshed with a vertical toothed plate 16; a limiting block 19 is fixedly connected to the side of the vertical toothed plate 16 away from the spur gear 15, and a dovetail chute for accommodating the limiting block 19 is formed on the side wall of the linkage seat 17; a first spring 20 is arranged on the bottom wall of the dovetail chute, and the upper end of the first spring 20 is fixedly connected to the limiting block 19. A rectangular slot for accommodating the connection bar 13 is formed on the side wall of the rear vertical plate 1, and a convex block matching with the wedge block 21 is arranged on the top wall of the rectangular slot. When the wedge block 21 contacts the convex block, its inclined surface will be squeezed by the convex block and retracted into the narrow slot; and narrow slot long chutes matching with the central shaft are recessed on both sides of the rectangular slot.

[0044] Furthermore, by setting the spur gear 15, the vertical toothed plate 16, the limiting block 19 and the first spring 20 to cooperate with each other, it can be ensured that while the connection bar 13 moves up and down together with the linkage seat 17, it can quickly turn upwards when the linkage seat 17 moves to the top position of the rear vertical plate 1, which is convenient for cable assembly; and when the connection bar 13 moves upwards, the wedge block 21 is first squeezed by the top wall of the rectangular slot and retracted into the narrow slot, and the vertical toothed plate 16 is later squeezed downwards by the top wall of the rectangular slot after the wedge block 21.

[0045] As Figure 5 and Figure 6 shown, the support rod 12 is rotationally matched with the longitudinal movable seat 10, and no less than two groups of matching roller rods 26 are commonly connected to the first bottom plate 2 and the second bottom plate 3; the matching roller rods 26, the upper limit rod 14, the adjusting pressure rod 11 and the support rod 12 are all telescopic rods, and the matching roller rods 26, the upper limit rod 14, the adjusting pressure rod 11 and the support rod 12 are all in rolling contact with the cable. Such a setting facilitates a smoother wiring process; reduces the frictional damage of the cable during the laying and bridge adjustment processes, ensures the stable performance of the cable, and improves the reliability of the entire cable wiring system.

[0046] During use: First, determine the total width of the layout according to the number of cables to be assembled. At this time, rotate the horizontal adjustment handle 23 to drive the horizontal lead screw 25 to rotate. Under the screwing action of the internal and external threads, the lead screw nut 24 drives the first bottom plate 2 to slide on the second bottom plate 3, so as to adjust the distance between the front vertical plate 4 and the rear vertical plate 1, and thus set the width of the cable tray to be the same as the required width. Then, select the corresponding number of unit cable tray components for splicing according to the total length of the cable layout. After the cable tray is assembled, first lay a row of cables flat on the first bottom plate 2 and the second bottom plate 3. Then, rotate the longitudinal adjustment handle 1801 to drive the longitudinal drive screw 18 to rotate clockwise. Under the screwing action of the internal and external threads, the linkage seat 17 drives the connection bar 13 and the upper limit rod 14 to move downward.

[0047] In this process, the vertical tooth plate 16 first disconnects from the top wall of the rectangular slot before the wedge block 21 and quickly moves upward to return to its original position under the elastic force of the first spring 20. The vertical tooth plate 16 acts on the spur gear 15, causing the spur gear 15 to drive the connection bar 13 and the upper limit rod 14 to quickly rotate downward by 90° and then remain stationary. Immediately afterwards, the wedge block 21 also disconnects from the convex block on the top wall of the rectangular slot and quickly extends outward under the elastic force of the second spring 22 to limit the upper end of the connection bar 13. This enables the connection bar 13 to continue to move downward stably with the linkage seat 17, so that the upper limit rod 14 limits the upper end of the cable.

[0048] When the installation angle needs to be adjusted, unscrew the first adjusting sleeve 9 from the fixed screw 7 to release the pressing action on the right adjusting plate 8. At this time, the right adjusting plate 8 can be driven to rotate up and down by 0 - 90°. When the right adjusting plate 8 rotates downward or upward by 0 - 90°, the right adjusting plate 8 thereon acts on the moving frame 30, causing the moving frame 30 to move downward. The moving frame 30 acts on the longitudinal movable seat 10, causing the longitudinal movable seat 10 to drive the adjusting pressure rod 11 and the support rod 12 to move downward, so that the cable at the left adjusting plate 6 can adaptively give length compensation, avoid the cable being in a taut state, ensure the integrity of its physical structure, and extend the service life of the cable.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
