Their primary function is to prevent accidental injuries from the guy wires securing utility poles when they pass through or near live lines. Currently, most guy insulators are manufactured using the following method: upper and lower hooks are formed from metal rods. Due to structural limitations, the hooks must be pre-embedded within the porcelain clay during the molding process. After pressure molding, drying, and finalizing the shape, the hooks are placed together in a furnace and fired at high temperature to form a single unit with the porcelain body.

The operation is cumbersome. Compared with using a blank knife to trim the clay rod into shape, its production efficiency is low, and more equipment and molds are required; second, when the upper and lower draw hooks made of steel rods and the porcelain body are fired at a high temperature of more than 1000 degrees, due to the different high-temperature shrinkage of the porcelain blank and the steel rod material, the upper and lower draw hooks and the porcelain body will separate from each other due to shrinkage, or even fall off, and the utilization efficiency needs to be improved.

DETAILED DESCRIPTION

[0037] The present invention provides Figures 1 to 10 The illustrated drawing porcelain insulator with a reliable pouring connection structure comprises a porcelain body 1 having an integral through slot 2 formed thereon. The through slot 2 passes through the upper and lower ends of the porcelain body 1 and is concentric with the porcelain body 1. In actual use, the porcelain body 1 is fired separately.

[0038] Reference Figure 1 、 Figure 4 、 Figure 5 As shown in FIG, a positioning cylinder 3 is installed inside the through slot 2. The positioning cylinder 3 can be made of, but not limited to, high-strength hard materials, such as iron that has been insulated, and can be adjusted according to specific usage.

[0039] In the specific setting, the positioning cylinder 3 includes a cylinder section 301, a first limiting plate 302 and a second limiting plate 303. The cylinder section 301 is located inside the through groove 2, the first limiting plate 302 is fixedly connected to the top end of the cylinder section 301, and the second limiting plate 303 is fixed to the bottom end of the cylinder section 301 by a first screw 6; the outer diameters of the first limiting plate 302 and the second limiting plate 303 are both larger than the inner diameter of the through groove 2, which can limit the positioning cylinder 3.

[0040] Specifically, after the porcelain body 1 is made, the operator inserts the barrel section 301 into the interior of the through groove 2, and the first limit plate 302 abuts against the top of the porcelain body 1; then the adhesive 23 is poured between the outer wall of the positioning barrel 3 and the inner wall of the through groove 2, and the second limit plate 303 is fixed to the bottom end of the barrel section 301 using the first screw 6 (the barrel section 301 is provided with a threaded groove that cooperates with the first screw 6), and the second limit plate 303 abuts against the bottom end of the porcelain body 1. Since the outer diameters of the first limit plate 302 and the second limit plate 303 are both larger than the inner diameter of the through groove 2, the porcelain body 1 and the positioning barrel 3 can be quickly assembled, and the adhesive 23 bonding and mechanical fixation are coordinated to achieve reliable connection, which is convenient and safe to use.

[0041] In actual use, a plurality of first screws 6 are provided, and auxiliary welding can be performed between the barrel section 301 and the second limiting plate 303 for reinforcement, which can be adjusted according to specific use conditions.

[0042] Compared with the overall firing method in the prior art, the porcelain body 1 and the positioning cylinder 3 in the present invention are of split design, that is, the porcelain body 1 is fired at high temperature and then assembled into a whole with the positioning cylinder 3, which simplifies the manufacturing process of the wire drawing porcelain insulator and improves processing efficiency and product quality.

[0043] In addition, since the porcelain body 1 and the positioning cylinder 3 are a split assembly structure, if the porcelain body 1 or the positioning cylinder 3 is damaged, it can be replaced accordingly, reducing the cost of use, and the positioning cylinder 3 does not need to go through the firing step.

[0044] Reference Figure 1 、 Figure 4 、 Figure 5 and Figure 7 As shown in , the positioning cylinder 3 is provided with a first pull ring 4 and a second pull ring 5 at its upper and lower ends, respectively. The first stop plate 302 has two circular holes for the first pull ring 4 to slide in, and the second stop plate 303 has two circular holes for the second pull ring 5 to slide in. The first and second pull rings 4, 5 are arranged alternately, forming a chain-like connection structure. The first and second pull rings 4, 5 are used for connecting to external pull wires. They can be made of, but are not limited to, high-strength hard materials, such as insulated iron, and can be adjusted based on specific usage.

[0045] The first pull ring 4 and the second pull ring 5 are directly subjected to force. When the first pull ring 4 and the second pull ring 5 are pulled by external force, the pressure on the porcelain body 1 can be reduced, thereby extending the service life.

[0046] Reference Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 10As shown in , considering that the wire-pulling porcelain insulators in the prior art are usually rigidly connected, both ends will instantly bear a large tensile force during installation, which is prone to fatigue, deformation, etc., in order to improve the performance of the wire-pulling porcelain insulator, a buffer assembly is provided at the intersection of the first pull ring 4 and the second pull ring 5, and the buffer assembly includes an elastic telescopic rod 13, the bottom of the elastic telescopic rod 13 is fixedly connected to the first support sleeve 11, the first support sleeve 11 is overlapped on the bottom end of the inner ring of the first pull ring 4, the top of the elastic telescopic rod 13 is fixedly connected to the second support sleeve 12, the second support sleeve 12 is overlapped on the top end of the inner ring of the second pull ring 5, and the first support sleeve 11 and the second support sleeve 12 are both arc-shaped.

[0047] When the first pull ring 4 and the second pull ring 5 move in opposite directions due to external tension, the elastic telescopic rod 13 contracts along the axial direction of the positioning tube 3 to relieve the force and buffer the tension. Compared with the wire-pulling porcelain insulator in the prior art, the buffer assembly provided in the present invention can effectively reduce the tension on both ends of the wire-pulling porcelain insulator, avoid damage to the insulator caused by excessive tension, and improve the reliability and stability of the connection.

[0048] In addition, a first supporting sleeve 11 and a second supporting sleeve 12 are provided to support and limit the first pull ring 4 and the second pull ring 5 to ensure stability in use.

[0049] In actual use, insulating pads are provided on the concave sides of the first support sleeve 11 and the second support sleeve 12, and the first support sleeve 11, the second support sleeve 12, etc. can be made of but not limited to high-strength hard materials, such as iron that has been insulated, and can be adjusted according to specific usage.

[0050] In addition, the elastic telescopic rod 13 may also be replaced by a damping element in combination with a spring.

[0051] Reference Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 As shown in , in order to facilitate the connection and installation of the first pull ring 4 and the second pull ring 5, a notch 7 for the first pull ring 4 to pass through is opened on the second pull ring 5, and the length of the notch 7 is greater than the outer diameter of the first pull ring 4. In actual use, refer to Figure 4 、 Figure 5 , insert the barrel section 301 into the interior of the through groove 2, and the first limit plate 302 abuts against the top of the porcelain body 1, then pour adhesive 23 between the outer wall of the positioning barrel 3 and the inner wall of the through groove 2, push the first pull ring 4 to move downward, so that its bottom end extends from the bottom of the barrel section 301, and the operator inserts the second pull ring 5 into the first pull ring 4 through the notch 7 to achieve quick connection and installation of the first pull ring 4 and the second pull ring 5, and then install the elastic telescopic rod 13, the first support sleeve 11, and the second support sleeve 12.

[0052] The second pull ring 5 is provided with a threaded sleeve 9 for closing the gap 7, and an annular groove 8 is provided on the outer wall of the second pull ring 5. Figure 5 The annular groove 8 is located below the notch 7, and a threaded sleeve 9 is provided in the annular groove 8. The threaded sleeve 9 can both rotate and slide, and the threaded sleeve 9 is threadedly connected to the second pull ring 5 at a position above the notch 7, thereby closing the notch 7.

[0053] Before connecting the first pull ring 4 and the second pull ring 5, rotate the threaded sleeve 9 to open the gap 7. After the second pull ring 5 passes through the gap 7 into the first pull ring 4, rotate the threaded sleeve 9 in the opposite direction to close the gap 7 to ensure the strength of the first pull ring 4 and the second pull ring 5.

[0054] By providing structures such as the notch 7 and the threaded sleeve 9, the first pull ring 4 and the second pull ring 5 can be quickly connected and installed. If the first pull ring 4 or the second pull ring 5 is damaged, they can be replaced accordingly.

[0055] The outside of the threaded sleeve 9 is fixedly connected to a rotating sleeve 10 , the outer wall of which is a regular hexagon. The operator can use a conventional wrench or the like to connect with the rotating sleeve 10 and then rotate the threaded sleeve 9 .

[0056] Reference Figure 4 、 Figure 7 As shown in , the first connecting plate 21 is fixedly connected to the first pull ring 4 , and the second connecting plate 22 is fixedly connected to the second pull ring 5 . Both the first connecting plate 21 and the second connecting plate 22 are located inside the positioning tube 3 .

[0057] Specifically, when the first pull ring 4 and the second pull ring 5 move in opposite directions due to external tension, the elastic telescopic rod 13 contracts to unload the force and buffer. After the elastic telescopic rod 13 is completely contracted, the first connecting plate 21 abuts against the first limiting plate 302, and the second connecting plate 22 abuts against the second limiting plate 303, thereby achieving the limiting effect and effectively utilizing the positioning tube 3 and other structures to improve the connection strength of the first pull ring 4 and the second pull ring 5; at the same time, the first connecting plate 21 connects the two sides of the first pull ring 4, and the second pull ring 5 connects the two sides of the second pull ring 5, thereby ensuring the strength of the first pull ring 4 and the second pull ring 5 during use and preventing deformation.

[0058] Reference Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown in the figure, considering that the threaded sleeve 9 is easy to loosen when the wire porcelain insulator swings, in order to prevent the threaded sleeve 9 from loosening at will and to ensure the stability of the elastic telescopic rod 13, the first support sleeve 11 and the second support sleeve 12, a limit assembly is provided between the elastic telescopic rod 13 and the threaded sleeve 9 to lock them with each other, that is, the threaded sleeve 9 will not rotate at will and the elastic telescopic rod 13 will not tilt at will.

[0059] During the specific setting, the limiting assembly includes a slip ring 16, a support plate 17, a through hole 18, a threaded hole 19 and a second screw 20. The slip ring 16 is slidably set on the fixed section of the elastic telescopic rod 13, and the support plate 17 is fixedly connected to the outer ring of the slip ring 16. The through hole 18 is opened on the end of the support plate 17 away from the slip ring 16, and the threaded hole 19 is opened at the top of the threaded sleeve 9. The second screw 20 passes through the through hole 18 and docks with the threaded hole 19, and a plurality of threaded holes 19 can be provided to facilitate the second screw 20 to cooperate with any one of the threaded holes 19.

[0060] In order to limit the slip ring 16 and prevent it from sliding out at will, a first limiting ring 14 and a second limiting ring 15 are fixedly connected to the outer wall of the elastic telescopic rod 13. The limiting assembly is located between the first limiting ring 14 and the second limiting ring 15. The slip ring 16 is on the fixed section of the elastic telescopic rod 13 and can only slide between the first limiting ring 14 and the second limiting ring 15.

[0061] During actual use, the elastic telescopic rod 13, the first support sleeve 11, and the second support sleeve 12 are installed between the first pull ring 4 and the second pull ring 5, and the threaded sleeve 9 closes the gap 7. The second screw 20 is passed through the through hole 18 and docked with the threaded hole 19 to fix the support plate 17 on the top of the threaded sleeve 9. At this time, the threaded sleeve 9 will not loosen, ensuring the strength of the second pull ring 5. And supported and limited by the slip ring 16, the elastic telescopic rod 13 will not tilt at will, preventing it from slipping between the first pull ring 4 and the second pull ring 5. At the same time, the slip ring 16 can slide on the fixed section of the elastic telescopic rod 13 without affecting the axial contraction of the elastic telescopic rod 13 along the positioning tube 3.

[0062] The present invention provides a first pull ring 4, a second pull ring 5 and a buffer assembly, and the porcelain body 1 and the positioning cylinder 3 are designed as a split type, which simplifies the manufacturing process of the wire-drawing porcelain insulator, improves processing efficiency and product quality, and effectively reduces the tension on both ends of the wire-drawing porcelain insulator, avoiding damage to the insulator caused by excessive tension. At the same time, the threaded sleeve 9 and the buffer assembly are locked with each other, ensuring the reliability and stability of the connection, thereby improving the use efficiency of the wire-drawing porcelain insulator.

[0063] The slip ring 16, support plate 17 and second screw 20 can be made of, but not limited to, high-strength hard materials, such as iron that has been insulated, and can be enlarged in size and adjusted according to specific usage.

[0064] Working principle: the elastic telescopic rod 13, the first support sleeve 11 and the second support sleeve 12 are installed between the first pull ring 4 and the second pull ring 5, and the threaded sleeve 9 closes the gap 7. The second screw 20 is passed through the through hole 18 and docked with the threaded hole 19 to fix the support plate 17 on the top of the threaded sleeve 9. At this time, the threaded sleeve 9 will not loosen, ensuring the strength of the second pull ring 5. And supported and limited by the slip ring 16, the elastic telescopic rod 13 will not tilt at will, preventing it from slipping between the first pull ring 4 and the second pull ring 5. At the same time, the slip ring 16 can slide on the fixed section of the elastic telescopic rod 13 without affecting the axial contraction of the elastic telescopic rod 13 along the positioning tube 3.
