Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 A square nut gasket structure for increasing torque includes a gasket structure 1, wherein the gasket structure 1 includes a pin 11 and a square nut piece 12 arranged at the top end of the pin 11, a threaded hole 13 is penetrated through the middle end of the pin 11 and the square nut piece 12, and the square nut has a threaded hole and is flanging and tapped.
[0023] The pin 11 is inverted U-shaped, and slots 114 are provided on both sides of the lower end of the pin 11. The bottom end of the pin 11 can be inserted into the socket of the welding plate.
[0024] A recessed hole 111 is provided at the top of the pin 11, and the interior of the recessed hole 111 is communicated with the interior of the threaded hole 13. A positioning hole 112 is provided at the side end of the pin 11, and a positioning block 121 is installed at the side end of the square nut plate 12. The thickness of the positioning block 121 is consistent with the width of the positioning hole 112. The positioning block 121 is inserted into the interior of the positioning hole 112 to limit the position between the pin 11 and the square nut plate 12 to avoid displacement between the pin 11 and the square nut plate 12, which affects the torque of the gasket.
[0025] The side end of the positioning block 121 is threadedly installed with a bolt 123 , and the provided bolt 123 threadably fixes the positioning block 121 to the side end of the square nut plate 12 , so as to facilitate assembly and disassembly between the positioning block 121 and the square nut plate 12 .
[0026] A bevel tooth A113 is installed at the inner bottom end of the positioning hole 112, and a bevel tooth B122 is installed at the bottom end of the positioning block 121. The top end of the bevel tooth A113 contacts the bottom end of the positioning block 121, and the bevel tooth B122 meshes with the bevel tooth A113.
[0027] There are two groups of positioning blocks 121 , and the two groups of positioning blocks 121 are inserted into the positioning holes 112 to limit the position of the other nut plate 12 .

When the plate shakes as a whole, the positioning block 121 matches the positioning hole 112, and the bevel tooth B122 engages with the bevel tooth A113, which increases the torque of the gasket structure 1 and prevents the square nut piece 12 from moving randomly inside the pin 11, affecting the normal use of the gasket structure 1.
