[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0025] Reference Figure 1-6 , is an embodiment of the utility model, which provides a high-strength insulating cross arm, the high-strength insulating cross arm comprises a fixed half ring 1 and a side half ring 2, the two ends of the side half ring 2 are detachably connected to the fixed half ring 1 by bolts, the front and back sides of the fixed half ring 1 are fixedly connected with a cross frame 3, the axis of the cross frame 3 is perpendicular to the axis of the fixed half ring 1, the fixed half ring 1 and the side half ring 2 are coaxially arranged, the two cross frames 3 are coaxially arranged, a slider 4 is slidably inserted inside the cross frame 3, tooth grooves 5 are provided on the inner walls of the left and right sides of the cross frame 3, a double-sided tooth block 7 is provided below the slider 4, the upper surface of the slider 4 and the front and rear sides of the porcelain bottle 9 are slidably penetrated by a vertical plate 11, the lower end of the vertical plate 11 is connected to the corresponding double-sided tooth block 7 The upper surface is fixedly connected, and the vertical plate 11 makes the double-sided tooth block 7 only move up and down in the vertical direction relative to the corresponding slider 4. The upper surface of the double-sided tooth block 7 is fixedly connected with a tension spring 6, and the upper end of the tension spring 6 is fixedly connected to the slider 4. The bottom surface of the slider 4 is a recessed structure, and the upper end of the tension spring 6 is located inside the recessed structure of the slider 4, so that the tension spring 6 can pull the double-sided tooth block 7 to contact the slider 4. At this time, the left and right sides of the double-sided tooth block 7 are respectively engaged with the two tooth grooves 5, and the interior of the horizontal frame 3 and the upper part of the tooth groove 5 are stepped. The left and right sides of the slider 4 are rotatably connected with rollers 10, and the bottom surface of the roller 10 is in rolling contact with the stepped surface of the inner wall of the horizontal frame 3, and the roller 10 reduces the resistance encountered by the slider 4 when it moves.
[0026] The bottom surface of the double-sided tooth block 7 is fixedly connected with a hook 8, and the double-sided tooth block 7 can be pulled downward by pulling the hook 8. A porcelain bottle 9 is installed on the upper surface of the slider 4. End plates 15 are provided on the sides of the two transverse frames 3 away from each other. The end plates 15 are detachably connected to the adjacent transverse frames 3 by bolts. After the end plates 15 are removed, the number of sliders 4 in the transverse frame 3 can be changed, and then the number of porcelain bottles 9 can be changed, so that the number of installed wires can be changed.
[0027] A baffle 12 is provided below the transverse frame 3, and the lower end of the double-sided tooth block 7 is located above the baffle 12. A tension telescopic rod 13 is fixedly connected to the right side of the transverse frame 3, and the right end of the tension telescopic rod 13 is fixedly connected to the adjacent baffle 12. A force rod 14 is rotatably passed through the front of the baffle 12 and located on the right side of the transverse frame 3. The tension telescopic rod 13 has the function of pulling the baffle 12 below the double-sided tooth block 7, so that the double-sided tooth block 7 can stably engage with the tooth groove 5, and stably limit the position of the slider 4. When the position of the slider 4 needs to be changed, the force rod 14 is pushed by a long rod-shaped object to move the baffle 12 away from the transverse frame 3. When the operator is working, he only needs to carry a longer rod-shaped object and a longer object to be hooked, and can operate the force rod 14 and the hook 8 at a higher position without climbing.
[0028] During use, the tension spring 6 engages with the tooth groove 5 by pulling the double-sided tooth block 7 upwards, thereby fixing the position of the slider 4 and then fixing the position of the wires installed on the porcelain bottle 9. When the position of the porcelain bottle 9 needs to be changed, the force-bearing rod 14 is pushed by a long rod-like object to cause the baffle 12 to stretch the tension telescopic rod 13 out of the bottom of the double-sided tooth block 7, and the hook of the long rod is hung on the surface of the hook 8, pulling the double-sided tooth block 7 to stretch the tension spring 6 out of the tooth groove 5, which can drive the porcelain bottle 9 installed on the slider 4 to change its position, thereby changing the distance between the wires without climbing to a high place.
