The insulator shell comprises an umbrella-shaped shell and a fixed shell. The umbrella-shaped shell is fixedly connected to the fixed shell. Anti-muck grooves that are compatible with the U-shaped screws are respectively provided on both sides of the fixed shell. The anti-muck grooves are respectively connected to the inner side of the U-shaped screws with buckles and limiters.

[0008] Furthermore, the fixed shell is arranged at the upper end of the umbrella-shaped shell, and the fixed shell is arranged as a fixed column with a diameter slightly smaller than the diameter of the outer wall of the umbrella-shaped shell.

[0009] Furthermore, the U-shaped screw includes a bending portion, a supporting portion and a threaded portion. The two ends of the lower surface of the bending portion are fixedly connected to the supporting portion. The lower ends of the supporting portions are respectively provided with threaded portions, and the threaded portions are provided with evenly distributed thread grooves.

[0010] Furthermore, the threaded portion is engaged with the upper flat washer, the lower flat washer and the nut from top to bottom respectively, a spring washer is sleeved on the threaded portion, the upper flat washer and the lower flat washer are arranged as ring pieces engaged with the threaded portion, the inner walls of the inner rings of the upper flat washer and the lower flat washer are respectively provided with thread strips adapted to the thread groove, and the inner wall of the nut is provided with a thread strip adapted to the thread groove.

[0011] Furthermore, the upper surface of the upper flat washer contacts the lower end of the support part, the lower surface of the upper flat washer contacts one side of the pressure plate, the other side of the pressure plate contacts the lower flat washer, and both sides of the spring washer contact the lower flat washer and the nut respectively.

[0012] Furthermore, fixing holes matching the threaded parts are respectively provided around the pressing plate.

[0013] Furthermore, a U-shaped groove is provided in the middle of the upper surface of the pressure plate, and the inner wall of the U-shaped groove is set to an arc with an upward opening adapted to the transmission line. The pressure plate is connected to the transmission line through the U-shaped groove, and the four sides of the upper surface of the pressure plate are respectively connected to the two ends of the U-shaped screws through fixing holes.

[0014] Furthermore, a flat groove is provided in the middle of the upper surface of the pressure plate, and the flat groove is provided as a square groove with the opening upward. The pressure plate is tightly connected to the transmission line through the flat groove, and the four sides of the lower surface of the pressure plate are respectively connected to the two ends of the U-shaped screws through fixing holes.

[0015] The present invention provides another technical solution, a convenient method for replacing porcelain bottle binding wire fittings, comprising the following steps:

[0016] Step 1: Place the inner side of the upper end of the U-shaped screw in contact with the anti-mistake groove on the upper end of the insulator shell, install the upper flat washers on both ends of the U-shaped screw, and pass the U-shaped screw through the pressure plate;

[0017] Step 2: After engaging the lower flat washer with both ends of the U-shaped screw, install the spring washer and nut in sequence.

[0021] 2. The present invention proposes a convenient type of hardware for replacing porcelain bottle binding wires and a method thereof. The bending portion is based on the umbrella-shaped structure of the insulator shell, so that the U-shaped screw and the insulator shell are tightly locked without a gap. The lower surface of the upper flat washer contacts one side of the pressure plate, which increases the contact area between the U-shaped screw and the pressure plate, and at the same time avoids the spring washer from damaging the surface of the pressure plate when removing the U-shaped screw. The spring washer effectively prevents the U-shaped screw from loosening due to vibration or thermal expansion and contraction between the transmission line and the pressure plate, causing the pressure plate to fall off. At the same time, it simplifies the installation steps, greatly improves the installation efficiency, reduces the labor force of workers, and effectively reduces labor costs.

[0022] 3. The present invention proposes a convenient type of hardware for replacing porcelain bottle binding wires and a method thereof. According to the different diameters of the transmission lines, a corresponding U-shaped groove pressure plate or a flat groove pressure plate is selected for installation. The U-shaped groove pressure plate is used in the forward direction and is more suitable for large-diameter transmission lines. The flat groove pressure plate is used in the reverse direction and is more suitable for small-diameter transmission lines. It can be used with U-shaped screws to lock the insulator and compact the wire, which is truly convenient and easy to operate. It also plays a role in buffering and protecting the transmission lines, thereby improving the safety of power transmission, having high flexibility of use, low production cost, firm connection and high economic benefits.

The insulator shell 1 includes an umbrella shell 11 and a fixed shell 12. The umbrella shell 11 is fixedly connected to the fixed shell 12. The umbrella is open and has good self-cleaning performance. The two sides of the fixed shell 12 are respectively provided with anti-idiot grooves 13 adapted to the U-shaped screw 2. The anti-idiot grooves 13 are respectively connected with the inner side buckle limiter of the U-shaped screw 2. The fixed shell 12 is set At the upper end of the umbrella-shaped shell 11, the fixed shell 12 is configured as a fixed column with a diameter slightly smaller than the outer wall diameter of the umbrella-shaped shell 11. The U-shaped screws 2 are respectively fixed to both sides of the fixed shell 12. A limiting groove for the transmission wire to pass through is provided in the center of the upper surface of the fixed shell 12. The anti-misalignment groove 13 is used to limit the insulator shell 1 and the U-shaped screw 2 respectively, so as to prevent the U-shaped screw 2 from sliding or rotating due to the umbrella structure of the insulator shell 1 and the U-shaped screw 2 when installing the insulator shell 1. This greatly improves the installation stability, reduces the installation time, and improves the installation efficiency.

When the surface of the pressure plate 3 is damaged, the two sides of the spring washer 26 are in contact with the lower flat washer 25 and the nut 27 respectively, preventing the U-shaped screw 2 from loosening due to vibration or thermal expansion and contraction of the transmission wire and the pressure plate 3, causing the pressure plate 3 to fall off. At the same time, the installation steps are simplified, the installation efficiency is greatly improved, the labor force of workers is reduced, and the labor cost is effectively reduced. The pressure plate 3 is connected to the transmission wire by a buckle through the U-shaped groove 32. The pressure plate 3 is used in the forward direction, which is simple and convenient, easy to operate, and plays a role in buffering and protecting the transmission wire, thereby improving the safety of power transmission and is more suitable for large-diameter transmission wires. In combination with the U-shaped screw 2, it can both lock the insulator and compact the wire, truly achieving convenient operation.
