[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Figure 1 and Figure 2 The illustrated anti-loosening power fitting clamp includes a clamp plate 1. A clamp plate 4 is fixed to the surface of the clamp plate 1 by means of several fasteners 5. An anti-loosening device 2 is provided on the surface of the clamp plate 1. The anti-loosening device 2 improves the stability of the conductor assembly on the clamp plate 1 by means of a fixing seat 21 and a nylon rope loop 25.

[0025] Figure 1 - Figure 3The anti-loosening device 2 shown includes a fixing base 21, which is fixedly connected to the surface of the wire clamp plate 1. Two mounting rods 22 are fixedly installed on one side of the surface of the fixing base 21. A fixing ring 23 is slidably arranged on the surface of the two mounting rods 22. Several evenly distributed circumferential connecting posts 24 are fixedly connected to one side of the fixing ring 23, and a nylon rope loop 25 is fixedly installed at one end of the several connecting posts 24. Fixing rings 26 are respectively installed on the arc surface of the two mounting rods 22 by means of threads. When using the wire clamp to install the wires of the power equipment, the wire clamp plate 1 is first installed and fixed to the terminal connection of the equipment by means of bolts. Then, the wire is placed in the assembly position of the wire clamp plate 1. Then, several clamp plates 4 are fixed to the surface of the wire clamp plate 1 by means of fasteners 5, so that the clamp plates 4 contact and press the surface of the wire to fix the position of the wire. At this point, the wire passes through the inner wall of the fixing base 21 and is inserted into the inner wall of the nylon rope loop 25 and the fixing ring 23. Then, the fixing ring 26 on the two mounting rods 22 is rotated. The rotation of the thread of the fixing ring 26 will squeeze and push the fixing ring 23. Moreover, the cross-section of the hole in the inner wall of the fixing base 21 is trapezoidal, so the nylon rope loop 25 will gradually increase the squeezing strength of the inner wall of the fixing base 21 under the squeezing of the fixing ring 23. At the same time, it will also squeeze the surface of the wire. When the wire becomes loose and slips, it will be stuck in the inner wall of the fixing base 21 with the help of the nylon rope loop 25, which will further strengthen and stabilize the wire. At this time, when the hardware clamp is used, it can increase the friction between the wire and the wire, so that the installation of the wire is more stable and firm, and it is not easy to loosen and detach during use. It also ensures the normal and safe operation of the power equipment and improves the reliability and stability during use.

[0026] Figure 3 and Figure 4 The inner wall of the nylon rope loop 25 shown is equipped with a reinforcing tube 28, which improves the reinforcement effect of the device. The sponge material of the reinforcing tube 28 makes the nylon rope loop 25 fit more closely with the wire, making it less likely to have gaps. This makes the nylon rope loop 25 more firmly reinforce and limit the wire. The inner wall of the fixing base 21 is fixedly connected with a reinforcing sleeve 27, which improves the limiting effect of the fixing base 21. The rubber material of the reinforcing sleeve 27 further increases the friction when the nylon rope loop 25 contacts and squeezes the trapezoidal inner wall of the fixing base 21, thus making the position of the nylon rope loop 25 more stable.

[0027] Figure 3 and Figure 4Washers 29 are respectively fitted on the arc surfaces of the two assembly rods 22 shown. The washers 29 improve the stability of the fixing ring 26. The washers 29 make the fixing ring 26 fit more tightly when it contacts and presses against the surface of the fixing ring 23, and also make the fixing ring 26 less prone to rotation and loosening, thus ensuring the stability of the position of the fixing ring 23. A reinforcing component 3 is installed at one end of both assembly rods 22. The reinforcing component 3 further improves the installation and reinforcement effect of the wire. The reinforcing component 3 makes the anti-loosening device 2 more stable and secure in limiting and fixing the wire.

[0028] Figure 4 and Figure 5 The reinforcement component 3 shown includes a connecting plate 31, which is fixedly connected to one end of each of the two mounting rods 22. A threaded rod 32 is threadedly connected to the surface of the connecting plate 31, and a pressure plate 33 is rotatably connected to one end of the threaded rod 32. The pressure plate 33 is slidably connected to the surface of the two mounting rods 22. When the anti-loosening device 2 reinforces the wire, the threaded rod 32 on the connecting plate 31 is rotated, thereby causing the pressure plate 33 at one end to slide on the arc surface of the two mounting rods 22. Because the wire is composed of several aluminum wires and the cross-section of one end of the pressure plate 33 is triangular, the tip of the pressure plate 33 will break the wire and expand the end of the wire, thereby dividing the wire into two parts and hanging them on the surface of the fixing ring 23. At this time, the wire will be more stable and firm and less prone to loosening.

[0029] Figure 4 and Figure 5 A positioning ring 34 is threaded onto the arc surface of the threaded rod 32 shown. The positioning ring 34 improves the positional stability of the pressure plate 33. With the positioning ring 34, after the pressure plate 33 contacts and presses against one end of the wire, the positioning ring 34 is rotated to contact and press against one side of the connecting plate 31. At this time, the position of the threaded rod 32 is more stable and firm, and it is not easy to rotate, thus ensuring the positional stability of the pressure plate 33.

[0030] Working principle: When using wire clamps to install wires in electrical equipment, firstly, the wire clamp plate 1 is installed and fixed to the terminal connection of the equipment using bolts. Then, the wire is placed in the assembly position of the wire clamp plate 1. Next, several clamp plates 4 are fixed to the surface of the wire clamp plate 1 using fasteners 5, so that the clamp plates 4 contact and press the surface of the wire, fixing the position of the wire. At this time, the wire passes through the inner wall of the fixing base 21 and is inserted into the inner wall of the nylon rope loop 25 and the fixing ring 23. Then, the fixing ring 26 on the two assembly rods 22 is rotated. The rotation of the threads of the fixing ring 26 will squeeze and push the fixing ring 23. The inner wall hole of the fixing base 21 has a trapezoidal cross-section, so the nylon rope loop 25 will gradually increase the compression strength with the inner wall of the fixing base 21 under the compression of the fixing ring 23. At the same time, it will also contact and compress the surface of the wire. When the wire becomes loose and slips, it will be stuck in the inner wall of the fixing base 21 with the help of the nylon rope loop 25, which will further strengthen and stabilize the wire. At this time, when the hardware clamp is used, it can increase the friction between the wire and the wire, so that the installation of the wire is more stable and firm, and it is not easy to loosen or detach during use. It also ensures the normal and safe operation of the power equipment and improves the reliability and stability during use.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
