Description

Technical Field

[0001] This utility model relates to the field of cable trays, and in particular to an adjustable cable tray for cable laying. Background Technology

[0002] Aluminum control cabinets typically refer to aluminum alloy control cabinets and aluminum profile control cabinets. They are mainly used for controlling and protecting circuits. The wiring inside the control cabinet is a meticulous and important process, which is directly related to the safe and stable operation of the electrical system. Wiring reels can be used to assist in unwinding the cables during the wiring process.

[0003] The existing cabling reels still have the following problems when in use: The area of ​​the cable placement area at the bottom of the existing cabling reels is not adjustable. This makes it unstable to place some cable loops with a large number of turns and a large outer diameter, which may affect the subsequent cabling efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide an adjustable cable reel for cable laying that allows for easy adjustment of the usable area at the bottom of the reel and ensures the efficiency of cable unwinding.

[0005] The technical solution to achieve the purpose of this utility model is: an adjustable cable tray for cable laying, having an initial base; a middle column is fixedly installed on the top of the initial base, and a coiled cable is movably fitted on the outer ring of the middle column; an extension plate is movably installed on the top of the initial base through an extension drive assembly, and a side plate is fixedly installed at the end of the extension plate; a limiting assembly is provided on the middle column for limiting the installation of the coiled cable; a movable cavity is provided inside the initial base, and the top of the movable cavity is connected to a strip groove; a rotating shaft is rotatably connected inside the rotating groove at the bottom of the initial base, and the rotating shaft is rotatably connected to the base plate.

[0006] The above technical solution describes the use of four extension plates, which are arranged in a ring. The angle difference between two adjacent extension plates is 90 degrees, which facilitates the movement of the extension plates to support cables of different diameters.

[0007] The above technical solution describes a total of four side panels, and each of the four side panels is fixedly connected to the ends of the four extended plates away from the central column.

[0008] The limiting component described in the above technical solution includes a threaded ring that is threadedly connected to the outer ring of the intermediate column, and two crossbars are fixedly connected to the outer wall of the threaded ring. The two crossbars are symmetrically arranged with reference to the central axis of the threaded ring as an axis of symmetry. The crossbars are used to appropriately limit the winding of the cable on the initial chassis, preventing the cable from becoming tangled during the unwinding and pulling process.

[0009] The extended drive assembly described in the above technical solution includes a motor fixedly connected to a vertical surface reserved on the side wall of the initial chassis, and the output shaft of the motor is driven by a threaded long rod, and the threaded long rod is driven by a bevel gear set and a threaded short rod.

[0010] The extended drive assembly described in the above technical solution also includes a movable block that is threadedly connected to the threaded long rod and the threaded short rod. The top of the movable block is fixedly connected to the bottom surface of the end of the extended plate near the middle column via a connecting rod, which is used to drive the extended plate to unfold and retract.

[0011] The outer ring of the threaded long rod described in the above technical solution is provided with two sections of threads with different directions. The two sections of threads with different directions are threadedly connected to two movable blocks respectively, and the other two movable blocks are threadedly connected to two threaded short rods respectively. The outer ring threads of the two threaded short rods are in the same direction, and both the threaded long rod and the threaded short rods are rotatably connected to the "+" shaped movable cavity to ensure that the direction of movement of the extended plate is controllable after the two threaded rods rotate.

[0012] The bevel gear set described in the above technical solution consists of three meshing bevel gears, and the three bevel gears are respectively fixedly sleeved on the outer ring of the threaded long rod and two oppositely arranged threaded short rods.

[0013] In the above technical solution, the sidewalls of the four movable blocks are attached to the inner wall of the "+" shaped movable cavity to achieve a sliding connection, ensuring the stability of the extended plate's movement.

[0014] After adopting the above technical solution, this utility model has the following positive effects:

[0015] During use, the drive motor rotates, causing the long threaded rod to rotate, which in turn causes the short threaded rod to rotate via a bevel gear set. This allows the movable block, which is threadedly connected to the long and short threaded rods, to move inside the movable cavity, thereby causing the four sets of extended plates to unfold or retract. This facilitates adjustment of the usable area at the bottom of the reel, allowing the size of the wiring reel to be adjusted according to the size of the rolled cable, so that the wiring reel occupies space reasonably and improves the compactness of the rolled cable support.

[0016] Cables with different outer diameters are placed on the initial chassis for subsequent wiring operations. Cables with larger outer diameters are supported at the bottom by an extension plate to prevent the outer diameter of the cable from collapsing during unwinding, which would affect the unwinding process.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] An adjustable cable reel for cable laying includes an initial base 1. A central post 2 is fixedly mounted on the top of the initial base 1, and a coil of cable is movably fitted around the outer ring of the central post 2. An extension plate 3 is movably mounted on the top of the initial base 1 via an extension drive assembly 9, and a side plate 4 is fixedly mounted at the end of the extension plate 3. A limit assembly 5 is provided on the central post 2 for limiting the installation of the coil of cable. An active cavity 6 is provided inside the initial base 1, and the top of the active cavity 6 communicates with a strip groove 7. A rotating shaft 10 is rotatably connected inside a rotating groove at the bottom of the initial base 1, and the rotating shaft 10 is rotatably connected to the base plate 11. This allows for convenient pulling and unwinding of the coil of cable on the overall cable reel. The rotating shaft 10 can be connected to the initial base 1 via a bearing to further improve rotational flexibility.

[0024] The length of the groove 7 limits the lateral movement range of the connecting rod 906. The connecting rod 906 can only move within the length range of the groove 7. The length of the threads on the threaded long rod 902 and the threaded short rod 903 is longer than the length range of the groove 7 to prevent the movable block 905 from coming out of the thread.

[0025] During use, the drive motor 901 (or a manual rotation structure to reduce product costs) rotates, causing the threaded long rod 902 to rotate. This rotation is transmitted through the bevel gear set 904, causing the threaded short rod 903 to rotate. This allows the movable block 905, which is threadedly connected to the threaded long rod 902 and the threaded short rod 903, to move inside the movable cavity 6, thereby causing the four sets of extended plates 3 to unfold or retract. This makes it convenient to place cables of different outer diameters on the initial chassis 1 for subsequent wiring operations. Cables with larger outer diameters are supported at the bottom by the extended plates 3, preventing accidents during cable unwinding.

[0026] To facilitate the placement of cables of different diameters on the initial chassis 1 for cabling, four extension plates 3 are provided in total, arranged in a ring. The angle difference between two adjacent extension plates 3 is 90 degrees, which facilitates the movement of the extension plates 3 to support cables of different diameters. Four side upright plates 4 are also provided, and the four side upright plates 4 are fixedly connected to the ends of the four extension plates 3 away from the central column 2. In this way, the bottom of cables with larger outer diameters is supported by the extension plates 3, preventing accidents during cable unwinding.

[0027] The limiting component 5 includes a threaded ring 501 that is threadedly connected to the outer ring of the intermediate post 2. Two crossbars 502 are fixedly connected to the outer wall of the threaded ring 501, and the two crossbars 502 are symmetrically arranged with reference to the central axis of the threaded ring 501. By twisting the threaded ring 501, the threaded ring 501 and the two crossbars 502 can be connected to the intermediate post 2 at different heights. This allows the two crossbars 502 to appropriately limit the top of the coiled cable, mainly preventing the cable from jumping out during unwinding and preventing tangling during the unwinding process. When a new coiled cable needs to be fitted onto the outer ring of the intermediate post 2, the threaded ring 501 is rotated to separate its threads from the intermediate post 2, allowing the new coiled cable to be fitted onto the outer ring of the intermediate post 2. The length of the crossbars 502 can be selected according to the different sizes of coiled cables to serve as the limiting component 5. Therefore, various sizes of limiting components 5 can be manufactured, with different lengths of the crossbars 502 in each limiting component 5.

[0028] The extended drive assembly 9 includes a motor 901 fixedly connected to a vertical surface 8 reserved on the side wall of the initial chassis 1. The output shaft of the motor 901 is driven by a threaded long rod 902, and the threaded long rod 902 is driven by a threaded short rod 903 through a bevel gear set 904. The bevel gear set 904 consists of three meshing bevel gears, which are respectively fixedly sleeved on the outer rings of the threaded long rod 902 and the two oppositely arranged threaded short rods 903. The outer ring of the threaded long rod 902 is provided with two threads with different directions. The two threads with different directions are threadedly connected to two movable blocks 905, and the other two movable blocks 905 are threadedly connected to two threaded short rods 903. The outer ring threads of the two threaded short rods 903 are in the same direction, and both the threaded long rod 902 and the threaded short rods 903 are rotatably connected to the "+" shaped movable cavity 6 to ensure that the movement direction of the extended plate 3 is controllable after the two threaded rods rotate.

[0029] The extended drive assembly 9 also includes a movable block 905 that is threadedly connected to the threaded long rod 902 and the threaded short rod 903. The top of the movable block 905 is fixedly connected to the bottom surface of the end of the extended plate 3 near the intermediate column 2 via a connecting rod 906. The connecting rod 906 slides inside the strip groove 7. The side walls of the four movable blocks 905 are attached to the inner wall of the "+" shaped movable cavity 6 to achieve a sliding connection. The four movable blocks 905 are arranged in a ring at equal angles to ensure the stable movement of the extended plate 3. This is used to drive the extended plate 3 to move open and close. At the same time, the length of the strip groove 7 is limited, and the connecting rod 906 can only move inside the strip groove 7. In this way, the length of the outer thread of the threaded long rod 902 and the threaded short rod 903 is longer than the movable length range inside the strip groove 7. This can prevent the movable block 905 from coming out of the thread range of the outer thread of the threaded long rod 902 and the threaded short rod 903.

[0030] Working principle: The drive motor 901 rotates, causing the threaded long rod 902 to rotate. This rotation is transmitted through the bevel gear set 904, causing the threaded short rod 903 to rotate. This causes the movable block 905, which is threadedly connected to the threaded long rod 902 and the threaded short rod 903, to move inside the movable cavity 6, thereby causing the four sets of extended plates 3 to unfold or retract. In this way, the bottom of the cable with a larger outer diameter is supported by the extended plates 3, preventing accidents during cable unwinding. At the same time, the extended plates 3 are convenient to carry when retracted, and the size of the wiring reel can be adjusted according to the size of the cable roll, so that the wiring reel occupies space reasonably and improves the compactness of the cable roll support.

[0031] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
