Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a multi-section combined expandable cable tray. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures, and are composed of supports, brackets, and installation accessories. Among them, the combined cable tray is a new type of cable tray, which is suitable for various projects, various units, and the laying of various cables. It has been widely used because of its simple structure, flexible configuration, convenient installation, and novel form.

[0003] Chinese utility model patent CN221150834U discloses a combined cable tray. In use, the adjusting rod and adjusting plate have threaded connections to their adjusting holes, and the guide rod and guide hole provide guidance, allowing the adjusting plate to slide relative to the adjusting groove. After the adjusting plate and front housing slide relative to the adjusting groove to the appropriate position, the width of the cable tray body is adjusted. However, specific width adjustment requires uniform adjustment of the width of multiple cable tray bodies, involving the coordinated operation of multiple components such as the adjusting rod, adjusting plate, and guide rod. This multi-step adjustment process may be cumbersome in actual operation, increasing the workload and installation time for installers, especially during large-scale installations, potentially leading to reduced efficiency. Therefore, this paper proposes a multi-segment combined expandable cable tray to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-segment combined expandable cable tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-segment modular expandable cable tray includes a front housing 1, a front housing 2, a rear housing 1, and a rear housing 2. The outer walls of the front housing 1 and the rear housing 1 are fixedly connected to sliders. The side walls of the front housing 2 and the rear housing 2 are provided with sliding grooves, and the sliders are slidably connected within these grooves. A drive mechanism for sliding the front housing 1 and the rear housing 1 is installed in the sliding groove within the front housing 2. Positioning rods are fixedly connected to the side walls of the front housing 1, the front housing 2, the rear housing 1, and the rear housing 2, and each has a positioning hole on its other side. The positioning rods are inserted into the corresponding positioning holes. Insert rods are slidably connected to the lower ends of the front housing 1, the front housing 2, the rear housing 1, and the rear housing 2, and these insert rods slidably extend into their corresponding positioning rods.

[0007] Preferably, the driving mechanism includes a threaded rod rotatably connected to a groove, and the slider is threadedly connected to the threaded section of the threaded rod.

[0008] Preferably, two sets of limiting rods are fixedly connected to the inner wall of the slide groove. The two sets of limiting rods are symmetrically positioned and slidably connected to the slider.

[0009] Preferably, a spring is sleeved on the outer wall of the insertion rod, one end of the spring is fixedly connected to the insertion rod, and the other end of the spring is fixedly connected to the bottom surfaces of the first front housing, the second front housing, the first rear housing, and the second rear housing, respectively.

[0010] Preferably, the outer wall of the insertion rod is in close contact with the inner wall of the positioning rod, and the radius of the end of the insertion rod is greater than the radius of its body.

[0011] Preferably, a rotating block is rotatably connected to the outer wall of the front housing, and the rotating block is coaxially and fixedly connected to the threaded rod.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the insertion of the positioning rod and the positioning hole, combined with the fixing of the insertion rod and the rotation of the threaded rod, allows for simultaneous adjustment of the width of the front and rear housings. This avoids the tedious steps of adjusting the width of each component of a multi-section cable tray, achieving uniform width adjustment. The synchronous adjustment not only reduces installation time but also improves the accuracy of adjustment, adapting to different cable wiring needs and effectively improving the ease of operation and efficiency of multi-section cable trays in practical applications.

[0014] 2. This utility model ensures a firm and stable connection by incorporating springs, insert rods, and other devices. The springs deform to ensure the insert rod fits snugly against the inner wall of the positioning rod and provide a reaction force to prevent loosening, thus ensuring the stability of the structure during use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A multi-segment modular expandable cable tray includes a front housing 1, a second front housing 2, a first rear housing 3, and a second rear housing 4. The front housing 1 and the second rear housing 3 are each fixedly connected to a slider 11 on their outer walls. The second front housing 2 and the second rear housing 4 are each provided with a sliding groove 8 on their side walls, in which the slider 11 is slidably connected. A driving mechanism for sliding the front housing 1 and the second rear housing 3 is installed in the sliding groove 8 within the second front housing 2. Positioning rods 5 are fixedly connected to the side walls of the front housing 1, the second front housing 2, the first rear housing 3, and the second rear housing 4, and each has a positioning hole 7 on its other side, in which the positioning rod 5 is inserted. Insert rods 12 are slidably connected to the lower ends of the front housing 1, the second front housing 2, the first rear housing 3, and the second rear housing 4, extending slidably into their corresponding positioning rods 5.

[0022] In practical use, when adjusting the width between the front housing 1, front housing 2, rear housing 3, and rear housing 4, the positioning rods 5 on one side of the rear housing 3 and rear housing 4 can be inserted into the positioning holes 7 on the side walls of the front housing 1 and front housing 2. The insertion rods 12 are used to connect them. With the rotation of the threaded rod 9, the width between the front housing 1, front housing 2, rear housing 3, and rear housing 4 can be adjusted simultaneously. It should be noted that only the groove 8 at the front housing 2 has the threaded rod 9 and the limiting rod 10 to avoid conflicts during unified adjustment.

[0023] The driving mechanism includes a threaded rod 9 rotatably connected to a groove 8, a slider 11 threadedly connected to the threaded section of the threaded rod 9, two sets of limiting rods 10 fixedly connected to the inner wall of the groove 8, the two sets of limiting rods 10 being symmetrically positioned and slidably connected to the slider 11, a spring 13 sleeved on the outer wall of the insertion rod 12, one end of the spring 13 being fixedly connected to the insertion rod 12, and the other end of the spring 13 being fixedly connected to the bottom surfaces of the first front housing 1, the second front housing 2, the first rear housing 3, and the second rear housing 4 respectively, the outer wall of the insertion rod 12 being in close contact with the inner wall of the positioning rod 5, the radius of the insertion rod 12 being larger than the radius of its body, a rotating block 6 rotatably connected to the outer wall of the second front housing 2, the rotating block 6 being coaxially fixedly connected to the threaded rod 9; with the deformable properties of the spring 13, the stability of the connection between the front and rear housings can be ensured after the front and rear housings are installed.

[0024] In this utility model, when the device is used, the front housing 1, the second front housing 2, the first rear housing 3, and the second rear housing 4 are arranged in their respective positions. Then, the positioning rods 5 on one side of the second rear housing 3 and the second rear housing 4 are inserted into the positioning holes 7 on the side walls of the first front housing 1 and the second front housing 2. At the same time, the slidingly connected insertion rod 12 is pressed and fixed on the positioning rod 5 under the action of the spring 13. The spring 13 ensures that the insertion rod 12 fits against the inner wall of the positioning rod 5 through deformation. The spring 13 provides reaction force support to the insertion rod 12 through elastic deformation, ensuring stability and anti-loosening effect during use. Thus, the connection between the front and rear housings is achieved.

[0025] Subsequently, the outer walls of the front housing 1 and the rear housing 3 are slidably connected to the sliding grooves 8 on the side walls of the front housing 2 and the rear housing 4 via the slider 11. At this time, by rotating the rotating block 6, the threaded rod 9 is driven to rotate, thereby pushing the slider 11 to slide along the sliding groove 8 on the threaded section of the threaded rod 9, completing the sliding adjustment between the front and rear housings. The rotation of the threaded rod 9 allows the front housing 1 and the rear housing 3 to slide in the sliding groove 8, thereby uniformly adjusting the width between the front housing 1, the front housing 2, the rear housing 3 and the rear housing 4.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
