[0002] In modern society, electrical engineering has become a crucial foundation supporting the operation of various fields. From lighting and household appliances in daily life to the operation of large-scale equipment in industrial production, from signal transmission in communication networks to power supply for transportation systems, electrical engineering is ubiquitous. It acts like an invisible yet incredibly resilient network, tightly connecting the entire society and ensuring its normal operation and the convenience of people's lives. When laying cables, cable clamps are often used to position them.

[0003] Existing cable fixing devices typically rely on multiple sets of bolts for assembly and disassembly. When cables need to be placed or subsequent maintenance is required, each bolt must be removed one by one, which is cumbersome and time-consuming. Therefore, we provide a cable fixing device for electrical engineering. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1-5 As shown, this utility model provides a cable fixing device for electrical engineering, including a fixing bracket 1. A locking block 3 is detachably installed on the top of the fixing bracket 1. Support legs 2 are fixedly installed on both sides of the bottom end of the fixing bracket 1. Support feet 4 are fixedly installed on the outer side of the bottom end of the support legs 2. Mounting holes are provided inside the support feet 4. Insertion slots 11 are provided on both sides of the top of the fixing bracket 1. Insertion protrusions 31 are fixedly installed on both outer surfaces of the locking block 3, and the insertion protrusions 31 are movably inserted into the insertion slots. Inside the 11, a locking hole 32 is provided on the front side of the insertion protrusion 31. A cavity 12 is provided inside the front housing of the insertion groove 11. A pull plate 13 is provided on the front housing of the cavity 12. A locking rod 14 is fixedly installed on the inner side of the pull plate 13. The other end of the locking rod 14 passes through the cavity 12 and extends into the interior of the locking hole 32. An anti-disengagement ring 15 is fixedly sleeved on the outer surface of the locking rod 14 inside the cavity 12. A return spring 16 is sleeved on the right side of the anti-disengagement ring 15 on the outer surface of the locking rod 14.

[0026] Furthermore, when it is necessary to place the cable, pull the pull plate 13 outward. The pull plate 13 drives the locking rod 14 to move outward along the cavity 12, so that the locking rod 14 disengages from the locking hole 32 of the plug-in protrusion 31. At the same time, the anti-disengagement ring 15 compresses the return spring 16. Then, pull the locking block 3 upward, so that the plug-in protrusion 31 disengages from the plug-in groove 11 of the fixed bracket 1. Place the cable into the cable fixing hole 17 at the top of the fixed bracket 1, align the plug-in protrusion 31 with the plug-in groove 11 and press the locking block 3 downward. After releasing the pull plate 13, the return spring 16 pushes the anti-disengagement ring 15 to drive the locking rod 14 to insert into the locking hole 32, thereby locking the locking block 3 with the fixed bracket 1 and completing the cable clamping.

[0027] Example 2

[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, cable fixing holes 17 are provided at the top of the fixing bracket 1 and the bottom of the locking block 3, a groove is provided on the inner wall of the cable fixing hole 17, a rotating rod 18 is fixedly installed on the inner wall of the groove, and a roller 19 is rotatably sleeved on the outer surface of the rotating rod 18.

[0029] Furthermore, when the cable needs to be pulled slightly, the cable contacts the roller 19 rotating around the rotating rod 18 in the groove of the inner wall of the cable fixing hole 17, which converts sliding friction into rolling friction, reduces wear on the cable insulation layer and lowers the pulling resistance.

[0030] Example 3

[0031] like Figure 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: preferably, the support leg 2 includes an upper support vertical plate and a lower support vertical plate, a hydraulic jack 21 is provided between the upper support vertical plate and the lower support vertical plate, a telescopic protective cover 22 is fixedly installed on the top of the lower support vertical plate, and the other end of the telescopic protective cover 22 is fixedly installed at the bottom of the upper support vertical plate.

[0032] Furthermore, when different installation heights are required, the PLC control system sends a command to the hydraulic jack 21. After the hydraulic jack 21 is started, the piston rod extends or retracts, causing the upper support plate and the lower support plate of the support leg 2 to move relative to each other, thereby adjusting the height of the fixed bracket 1 and the cable. During this process, the telescopic protective cover 22 on the top of the lower support plate stretches or retracts synchronously with the upper support plate, always covering the hydraulic jack 21 to prevent impurities from entering and affecting its use.

[0033] The solution uses a PLC as the core control component. The PLC establishes a connection with the hydraulic jack 21 through RS-485 communication. When the hydraulic jack 21 needs to be started, the PLC sends a start command to the hydraulic jack 21 to start it.

[0034] The working principle of this electrical engineering cable fixing device will be explained in detail below.

[0035] like Figure 1-5 As shown, when using the device, first determine the installation position according to the cable routing plan, align the support foot 4 with the mounting surface, and fix the device with expansion bolts or fastening screws through its internal mounting holes to ensure the bottom is stable. When it is necessary to place the cable, pull the pull plate 13 outward. The pull plate 13 drives the locking rod 14 to move outward along the cavity 12, causing the locking rod 14 to disengage from the locking hole 32 of the insertion protrusion 31. At the same time, the anti-disengagement ring 15 compresses the return spring 16. Then, pull the locking block 3 upward to disengage the insertion protrusion 31 from the insertion groove 11 of the fixed bracket 1. Place the cable into the cable fixing hole 17 at the top of the fixed bracket 1, align the insertion protrusion 31 with the insertion groove 11, and press the locking block 3 downward. After releasing the pull plate 13, the return spring 16 pushes the anti-disengagement ring 15 to drive the locking rod 14 to insert. The locking hole 32 is inserted to lock the locking block 3 and the fixed bracket 1, thus clamping the cable. When the cable needs to be pulled slightly, the cable contacts the roller 19 rotating around the rotating rod 18 in the groove of the inner wall of the cable fixing hole 17, converting sliding friction into rolling friction, reducing wear on the cable insulation layer and reducing pulling resistance. When different height installation requirements need to be met, the PLC control system sends a command to the hydraulic jack 21. After the hydraulic jack 21 is started, the piston rod extends or retracts, driving the upper support plate and the lower support plate of the support leg 2 to move relative to each other, thereby adjusting the height of the fixed bracket 1 and the cable. During this process, the telescopic protective cover 22 on the top of the lower support plate stretches or contracts synchronously with the upper support plate, always covering the hydraulic jack 21 to prevent impurities from entering and affecting its use.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
