[0028] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] Embodiment 1

[0030] As attached Figure 1 To Attachment Figure 2As shown, the present invention provides a box-type transformer low-voltage cable hiding mechanism, including a box-type transformer low-voltage cabinet 1, the box-type transformer low-voltage cabinet 1 is connected to other equipment through cables, the box-type transformer low-voltage cabinet 1 is provided with a first passage slot 2, the box-type transformer low-voltage cabinet 1 is fixedly connected with a guide plate 3, and a certain distance is provided between the first passage slot 2 and the second passage slot 4 by setting the position of the guide plate 3, thereby improving the limiting effect of the first passage slot 2 and the second passage slot 4 on the cable, the guide plate 3 is provided with a second passage slot 4, wherein the first passage slot 2 and the second passage slot 4 are provided with a plurality of groups, each The cables pass through the first through slot 2 and the second through slot 4 respectively, and the first through slot 2 and the second through slot 4 limit the passing cables to avoid the cables from being entangled with each other. The low-voltage cabinet 1 of the box-type transformer is connected with a fixing component 5, and the guide plate 3 is connected with an auxiliary component 6, wherein the fixing component 5 and the auxiliary component 6 are fixed to prevent the cables from bending and sticking together, and the fixing component 5 is connected with an installation component 7, wherein the installation component 7 enables the fixing component 5 to be quickly installed and disassembled in the low-voltage cabinet 1 of the box-type transformer, thereby facilitating the maintenance and replacement of the fixing component 5.

[0031] As can be seen from the above, the guide plate 3 is installed in the low-voltage cabinet 1 of the box-type transformer, and the guide plate 3 is kept at a suitable distance from the first through groove. The fixing component 5 is set above the first through groove 2 through the installation component 7. The cable passes through the first through groove 2 and the second through groove 4 to enter the interior of the low-voltage cabinet 1 of the box-type transformer. The first through groove 2 and the second through groove 4 cooperate to limit the passing cables so that different cables are located in different areas, thereby avoiding entanglement between the cables. The fixing component 5 and the auxiliary component 6 fix the two ends of the cable to avoid bending of the cable.

[0032] Embodiment 2

[0033] As attached Figure 3 To Attachment Figure 5As shown, this embodiment is basically the same as the previous embodiment, except that the fixing assembly 5 includes an inner ring 501, wherein the cable passes through the first passage slot 2 and then passes through the inner ring 501, the inner ring 501 is rotatably connected to the outer ring 502, wherein the outer ring 502 is fixed and the inner ring 501 can rotate, and the inner ring 501 is rotatably connected to the clamping plate 503, when the inner ring 501 rotates, the clamping plate 503 is driven to deflect, so that the clamping plate 503 is always in contact with the surface of the cable, the clamping plate 503 is connected to the movable rod 504, and the outer ring 502 is provided with a movable groove 505, when the clamping plate 503 deflects, the movable rod 504 is in the movable groove 505 The outer ring 502 is provided with a reset groove 506 to assist the deflection movement of the clamping plate 503. The inner ring 501 is fixedly connected with a reset rod 507. The reset rod 507 extends into the reset groove 506. The reset rod 507 is connected with a first spring 508. The first spring 508 is connected with a fixed rod 509. When the inner ring 501 rotates forward, the inner ring 501 drives the reset rod 507 to rotate forward. At this time, the traction force of the inner ring 501 is the first spring 508 being stretched and accumulating energy. When the external force disappears, the first spring 508 releases energy to restore to its original state. At this time, the first spring 508 drives the reset rod 507 to reverse, thereby driving the inner ring 501 to reverse.

[0034] Specifically, the fixed rod 509 is fixedly connected to the reset groove 506 , and the movable rod 504 is located in the movable groove 505 .

[0035] Furthermore, the fixing assembly 5 also includes a swing groove 510 opened on the outer ring 502, and the inner ring 501 is fixedly connected with a swing rod 511, which passes through the swing groove 510. The swing rod 511 can swing in the swing groove 510, and the inner ring 501 is driven to rotate forward and reverse by operating the swing rod 511.

[0036] Furthermore, the side of the clamping plate 503 close to the cable is an arc surface, which makes the clamping plate 503 more closely fit the size of the cable. The side of the clamping plate 503 close to the cable is provided with an elastic protrusion, wherein the elastic protrusion can increase the friction between the clamping plate 503 and the cable, thereby improving the fixing effect of the cable.

[0037] Furthermore, the auxiliary component 6 includes a ring 601 fixed on the guide plate 3, wherein the cable passes through the second passage groove 4 and then through the ring 601, the ring 601 is provided with a telescopic groove 602, and the telescopic groove 602 is slidably connected with a telescopic protrusion 603, and the telescopic protrusion 603 can slide in the telescopic groove 602, and the ring 601 and the telescopic protrusion 603 are provided with an annular groove 604, and the annular groove 604 has a limiting effect on the elastic ring 605 to prevent the elastic ring 605 from being separated from the ring 601 and the telescopic protrusion 603. An elastic ring 605 is placed in the annular groove 604, and when the telescopic protrusion 603 slides outward along the telescopic groove 602, the elastic ring 605 is stretched, and the deformed elastic ring 605 provides a reaction force, so that the telescopic protrusion 603 fits the cable, thereby clamping the cable to a limit.

[0038] Furthermore, the side of the telescopic protrusion 603 close to the cable is an arc surface, and the telescopic protrusion 603 fits better with the surface of the cable through the arc surface. The end of the telescopic protrusion 603 close to the cable is provided with an inclined surface. When the cable passes through the ring 601, the inclined surface of the telescopic protrusion 603 will be squeezed, thereby causing the telescopic protrusion 603 to slide outward along the telescopic groove 602.

[0039] As can be seen from the above, the cable passes through the first passage groove 2, the inner ring 501, the second passage groove 4 and the sleeve ring 601 in sequence and is connected to the box-type transformer low-voltage cabinet 1. When the cable is to pass through the inner ring 501, the swing rod 511 is operated to drive the inner ring 501 to rotate forward. When the inner ring 501 rotates, it drives the clamping plate 503 to deflect, so that the cable can pass through the inner ring 501. When the clamping plate 503 deflects, the movable rod 504 moves in the movable groove 505 to assist the deflection movement of the clamping plate 503. When the inner ring 501 drives the reset rod 507 to rotate forward, the reset rod 507 pulls the first spring 508, and the first spring 508 is stretched to store energy. When no external force is applied to the swing rod 511, the first spring 508 releases energy to restore the original state. At this time, the first spring 508 drives the reset rod 507 to reverse, and then drives the inner ring 501 to reverse. The inner ring 501 deflects the clamping plate 503 toward the cable, so that the clamping plate 503 fits the surface of the cable to fix one end of the cable.

[0040] When the cable is about to pass through the ring 601, the cable will squeeze the inclined surface of the telescopic protrusion 603, thereby causing the telescopic protrusion 603 to slide outward along the telescopic groove 602. The telescopic protrusion 603 stretches the elastic ring 605, and the deformed elastic ring 605 provides a reaction force, so that the telescopic protrusion 603 fits the cable, thereby clamping the other end of the cable to prevent the cable from moving.

[0043] Specifically, the two ends of the second spring 707 are fixedly connected to the positioning sleeve 701 and the plug plate 706 respectively, the positioning sleeve 701 is fixedly connected to the outer ring 502, the positioning rod 703 is fixedly connected to the box-type transformer low-voltage cabinet 1, and the positioning sleeve 701 and the positioning rod 703 are connected together by inserting the plug rod 705 into the slot 704, and then the outer ring 502 is installed on the box-type transformer low-voltage cabinet 1.

[0044] Furthermore, the first passage groove 2, the inner ring 501, the second passage groove 4 and the positioning sleeve 701 are located on the same axis, which is convenient for the cable to pass through.

[0045] As can be seen from the above, the insertion rod 705 is inserted into the slot 704, the positioning sleeve 701 and the positioning rod 703 are limited so that the two are connected together, and then the outer ring 502 is installed on the low-voltage cabinet 1 of the box-type transformer. When it is necessary to remove and replace the fixing component 5, the plug plate 706 is pulled outward, and the plug plate 706 drives the insertion rod 705 to separate from the slot 704. At this time, the limit between the positioning sleeve 701 and the positioning rod 703 is released, and the fixing component 5 can be pulled upward to complete the disassembly, and the reverse operation can complete the installation of the fixing component 5.
