Description

Technical Field

[0001] The field of cable fixing devices particularly relates to a cable fixing device, a cable fixing mechanism and an electrical control cabinet. Background Art

[0002] In the electrical field, control cabinets are often needed to control equipment. There are usually many lines in the control cabinet. When the lines are too messy, they are easy to get tangled with each other, which is not convenient for cable arrangement during subsequent wiring. Cables tangled with each other are prone to cause safety accidents. Usually, the cables inside the control cabinet need to be organized.

[0003] The traditional way to fix cables in an electrical control cabinet is to bundle all the cables together with cable ties, or to fix the cables one by one with components such as fixing buckles. When the cable ties are used, when the cables need to be replaced later, the cable ties can only be cut off, which is not convenient for reuse. Therefore, it is necessary to develop a cable fixing device for an electrical control cabinet. Utility Model Content

[0008] The beneficial effects of a cable fixing device are:

[0009] (1) The present application adopts the clamping body design of the clamping assembly, so that the cables can be neatly placed in the groove of the support column and clamped by the clamping mouth of the clamping body, thereby avoiding the situation where the cables are entangled with each other, making the cable arrangement more convenient and orderly.

[0010] (2) When the present application needs to replace the cable, the clamping drive assembly can drive the clamp body to rotate with the shaft as the point of rotation and release the cable through the clamp mouth. There is no need to cut the cable tie as in the traditional cable tie method, thus achieving the reuse of the cable and reducing waste.

[0011] (3) The main purpose of setting the groove on the support column of the present application is to better support and fix the cables. Specifically, this groove provides a clear position for the cables, so that the cables can be placed neatly and stably clamped by the clamping assembly. In this way, the cables will not be entangled with each other, which facilitates the cable arrangement during subsequent wiring and improves work efficiency. At the same time, neatly fixed cables also reduce possible safety accidents and improve the safety and reliability of the electrical control cabinet.

[0016] Furthermore, the top surface of the clamping body is provided with a baffle portion.

[0017] A second aspect of the utility model provides a cable fixing mechanism, the cable fixing mechanism comprising a mounting box, a second drive assembly, a third drive assembly and a plurality of cable fixing devices;

[0018] The second drive assembly, the third drive assembly and a plurality of cable fixing devices are all mounted on the mounting box;

[0019] The second driving assembly comprises a plurality of worm wheels and worms respectively mounted at the lower ends of the driving screws of the plurality of cable fixing devices, wherein the worms are provided with a plurality of spiral grooves matching with the plurality of worm wheels;

[0045] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0046] like Figure 1As shown, a cable fixing device a comprises a support column 1, a clamping assembly 2 and a clamping drive assembly 3; the upper end surface of the support column 1 is provided with a groove 11 for supporting the cable, and the groove 11 is semicircular, which can better support and fix the cable, and the cable fixing device a can be locked in the electrical control cabinet through the mounting portion 12 on the side of the support column 1 with screws; the clamping assembly 2 comprises a clamping body 21, and the clamping body 21 is symmetrically mounted on both sides of the support column 1 through a rotating shaft 22, and a clamping opening 23 for clamping the cable is provided at the side of the clamping body 21 corresponding to the groove 11; the clamping drive assembly 3 is used to drive the two clamping bodies 21 to use the rotating shaft 22 as the rotation point, and clamp or release the cable through the clamping opening 23.

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, the clamping drive assembly 3 includes a first linkage rod 31, a second linkage rod 32 and a drive ring 33. The drive ring 33 is arranged below the clamp body 21 and is sleeved on the support column 1. The first linkage rod 31 and the second linkage rod 32 are symmetrically arranged on both sides of the support column 1. The upper end of the first linkage rod 31 is rotatably connected to one of the clamp bodies 21, and the upper end of the second linkage rod 32 is rotatably connected to the other clamp body 21. The lower end of the first linkage rod 31 and the lower end of the second linkage rod 32 are rotatably connected to the drive ring 33 respectively.

[0048] like Figure 1 As shown, in this embodiment, the clamping drive assembly 3 also includes a first drive assembly, which is used to drive the drive ring 33 to perform lifting movements. The drive ring 33 drives the clamping mouth 23 of the clamping body 21 to clamp or release the cable through the first linkage rod 31 and the second linkage rod 32.

[0049] like Figure 1 As shown, in this embodiment, the first driving component is a driving screw 34, and the driving screw 34 is installed on the side of the support column 1 through a first mounting seat 36. A driving threaded hole 331 is provided on the driving ring 33. By rotating the driving screw 34, the driving screw 34 cooperates with the driving threaded hole 331 on the driving ring 33 to drive the driving ring 33 to perform lifting and lowering movements.

[0050] (1) In this embodiment, the lifting and lowering movement of the driving ring 33 can be precisely controlled by rotating the driving screw 34, thereby achieving precise adjustment of the cable clamping force. This precise control helps protect the cable and avoids cable damage caused by excessive clamping.

[0051] (2) In this embodiment, the operation of the driving screw 34 is simple and intuitive. The user can easily clamp or release the cable by rotating the screw without complicated tools or steps.

[0052] (3) In this embodiment, the driving screw 34 and the driving threaded hole 331 on the driving ring 33 are tightly matched, which can ensure that a stable clamping force is provided when clamping the cable to prevent the cable from loosening or falling off.

[0053] like Figure 3 As shown, in this embodiment, the clamping drive assembly 3 further includes a guide column 35 , which is mounted on the side of the support column 1 through a second mounting seat 37 , and the guide column 35 passes through a guide hole 332 on the drive ring 33 .

[0054] (1) The guide post 35 passes through the guide hole 332 on the driving ring 33, providing a stable guide for the lifting and lowering movement of the driving ring 33, thereby ensuring the stability and accuracy of the clamping opening 23 of the clamping body 21 when clamping or releasing the cable.

[0055] (2) Due to the guiding effect of the guide pillar 35, the driving ring 33 is not prone to deflection or shaking during the lifting process, thereby ensuring that the clamping effect of the clamping mouth 23 of the clamping body 21 on the cable is more reliable.

[0056] like Figure 1 As shown, in this embodiment, the top surface of the clamp body 21 is provided with a baffle portion 211. The baffle portion 211 can effectively prevent the cable from sliding upward or falling out of the clamp body 21 during the clamping process, protecting the cable from damage in the fixed position.

[0057] The working process of the cable fixing device a is:

[0058] The cable fixing device a can be locked in the electrical control cabinet through the mounting portion 12 on the side of the support column 1 with screws, and then multiple cables are placed in the groove 11 of the supporting cable, and then the clamping drive component 3 starts to work. By rotating the driving screw 34 of the clamping drive component 3 clockwise, the driving screw 34 cooperates with the driving threaded hole 331 on the driving ring 33 to drive the driving ring 33 to rise upward. The upward movement of the driving ring 33 will drive the first linkage rod 31 and the second linkage rod 32 to drive the clamping mouth 23 of the clamping body 21 to close and clamp the cable.

[0059] When the cable is to be released, the drive screw 34 of the clamping drive assembly 3 is rotated counterclockwise, and the drive screw 34 cooperates with the drive threaded hole 331 on the drive ring 33 to drive the drive ring 33 to descend. The downward movement of the drive ring 33 will drive the first linkage rod 31 and the second linkage rod 32 to drive the clamping mouth 23 of the clamping body 21 to open and release the cable.

[0060] Therefore, in this embodiment, the clamping body 21 of the clamping assembly 2 neatly places the cable in the groove 11 of the support column 1 and stably clamps it, effectively avoiding the cables from getting entangled with each other, making the cable arrangement more orderly and convenient. When the cable needs to be replaced, the clamping drive assembly 3 can easily drive the clamping body 21 to rotate to release the cable without destroying the fixings, thereby achieving the reuse of the cable and significantly reducing waste. The groove 11 design on the support column 1 not only provides a clear position for the cable, allowing it to be neatly placed and stably clamped, but also improves work efficiency and the safety and reliability of the electrical control cabinet.

[0061] like Figure 4 and Figure 5 As shown, a cable fixing mechanism b in this embodiment comprises a mounting box 4, a second drive assembly 5, a third drive assembly 6 and a plurality of cable fixing devices a; the second drive assembly 5, the third drive assembly 6 and a plurality of cable fixing devices a are all mounted on the mounting box 4; wherein the plurality of cable fixing devices a are mounted side by side and laterally in the mounting box 4, wherein the clamping body 21 of the cable fixing device a is located outside the mounting box 4, and the mounting box 4 is provided with a first avoidance hole 41 for avoiding the first linkage rod 31 and the second linkage rod 32 of the cable fixing device a, and a second avoidance hole 42 for avoiding the empty support column 1. During installation, the bottom plate of the mounting box is designed to be detachable, for example, connected by screws, so that the support column, the clamping drive assembly and the second drive assembly can be installed from below, and then the remaining components can be installed one by one.

[0062] like Figure 6 As shown, the second driving assembly 5 includes a plurality of worm wheels 51 and a worm 52 respectively mounted at the lower ends of the driving screws 34 of the plurality of cable fixing devices a, and the worm 52 is provided with a plurality of spiral grooves 53 cooperating with the plurality of worm wheels 51;

[0063] like Figure 7 As shown, the third driving assembly 6 includes a driving rod 61, a first bevel gear 62, a second bevel gear 63 and a knob 64. The upper end of the driving rod 61 is located outside the mounting box 4, the knob 64 is mounted on the upper end of the driving rod 61, the first bevel gear 62 is mounted on the lower end of the driving rod 61, and the second bevel gear 63 is mounted on one end of the worm 52. The knob 64 drives the driving rod 61 to rotate, and the driving rod 61 drives the second bevel gear 63 to drive the worm 52 to rotate through the first bevel gear 62. The worm 52 drives multiple worm gears 51 through the multi-segment spiral grooves 53 to respectively drive the driving screws 34 of multiple cable fixing devices a to rotate, and each driving screw 34 drives the driving ring 33 to perform lifting motion, and the driving ring 33 drives the clamping mouth 23 of the clamping body 21 to clamp or release the cable through the first linkage rod 31 and the second linkage rod 32.

[0064] The present application adopts the cooperation of the second and third drive components 6, which can drive multiple cable fixing devices a to work at the same time, significantly improving the efficiency of cable fixing and releasing. The user can control the fixing and releasing of the cable by simply operating the knob 64, without complicated steps, which reduces the difficulty of use. At the same time, the multi-segment spiral groove 53 design on the worm 52 ensures that each cable fixing device a can be accurately driven to achieve accurate fixing of the cable.

[0065] like Figure 7 As shown, further, mounting plates 43 are respectively provided on both sides of the mounting box 4, and mounting holes 44 are provided on the mounting plates 43.
