[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiments

[0028] This embodiment is a reinforced arm porcelain insulator.

[0029] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a reinforced arm porcelain insulator includes: a mounting base 1 and an arm porcelain insulator body 121 arranged on the mounting base 1;

[0030] An installation groove 2 and an adjustment groove 3 are provided inside the mounting seat 1. The adjustment groove 3 is located on the upper side of the mounting groove 2. A limit block 4 is provided inside the adjustment groove 3. The limit block 4 is symmetrical front to back about the vertical center axis of the mounting seat 1. The limit block 4 is rotatably connected to the bidirectional threaded rod 5. The bidirectional threaded rod 5 is threadedly connected to the limit column 6. The limit column 6 is slidably connected to the mounting seat 1. The limit column 6 is symmetrical left to right about the vertical center axis of the mounting seat 1. The limit block 4, the bidirectional threaded rod 5 and the limit column 6 correspond to each other one by one.

[0031] like Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, the mounting groove 2 is slidingly connected to the push plate 7, a connecting plate 8 is fixedly installed on the lower side of the push plate 7, a tooth plate 9 is provided on the side of the connecting plate 8, the tooth plate 9 is meshed with the gear 10, a one-way threaded rod 11 is provided on the right side of the gear 10, the one-way threaded rod 11 is rotatably connected to the mounting seat 1, a connecting seat 12 is provided on the upper side of the push plate 7, an umbrella skirt 13 is provided on the outer side of the connecting seat 12, and the connecting seat 12 is slidably connected to both the mounting groove 2 and the adjustment groove 3.

[0032] It should be noted that a connecting seat 12 is provided on the upper side of the push plate 7, and the arm porcelain insulator body 121 is connected to the mounting seat 1 through the connecting seat 12. An umbrella skirt 13 is provided on the outer wall of the arm porcelain insulator body 121. When in use, first install the mounting seat 1 in the corresponding working position, and then connect the high-voltage line to the connecting seat 12 and put it into use. Specific embodiments

[0033] This embodiment is intended to solve the problem of unstable support.

[0034] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 When the two-way threaded rod 5 is in the state of being moved left and right, the two limiting columns 6 on the outside of the two-way threaded rod 5 move in the same direction, which will cause one of the limiting columns 6 not to fit tightly with the connecting seat 12 when limiting the connecting seat 12, resulting in insufficient stability in the reinforcement. By rotating the two-way threaded rod 5, the two limiting columns 6 on the outside of the two-way threaded rod 5 move in opposite directions, thereby limiting the connecting seat 12, and then rotating the other two-way threaded rod 5 can prevent the connecting seat 12 from falling off the upper side of the mounting seat 1. Specific embodiments

[0035] This embodiment is intended to solve the problem of the connection base 12 shaking.

[0036] like Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, since the one-way threaded rod 11 is rotatably connected to the mounting base 1, when the one-way threaded rod 11 is rotated, the gear 10 will rotate, but the position of the gear 10 will not change. The rotation of the gear 10 will cause the tooth plate 9 to move up and down. When the tooth plate 9 moves up, it will move the push plate 7 up through the connecting plate 8. After the upper side of the push plate 7 is tightly fitted with the lower side of the connecting base 12, when the one-way threaded rod 11 cannot rotate, the one-way threaded rod 11 is stopped from rotating. At this time, the connecting base 12 will be clamped by the push plate 7 and the limit column 6, so that it will not shake. When connecting bases 12 of different sizes are installed inside the mounting base 1, they will not shake, and it has a wide range of applications.
