Embodiment

[0021] Please refer to Figures 1-4 The utility model provides a low torque high -efficient installation hub cover nut, including support component 1 including arc plate 11, one side of arc plate 11 is seted up with hexagonal groove 12, hexagonal groove 12 is seted up with round hole 13, and round hole 13 penetrates arc plate 11, and it is convenient for screw rod to pass through round hole 13 and hexagonal groove 12 and is connected with nut component 2 with screw thread, nut component 2 includes hexagonal block 21, and the central position of hexagonal block 21 is seted up with threaded hole 25, and threaded hole 25 penetrates hexagonal block 21, and the position of six corners of hexagonal block 21 near both sides is provided with arc angle 23, and the insertion of arc angle 23 is convenient for the tool, and one end of hexagonal block 21 is clamped in hexagonal groove 12, by the insertion of one end of hexagonal block 21 in hexagonal groove 12, the clamping connection between hexagonal groove 12 and hexagonal block 21 is carried out, so as to fix the position between hexagonal groove 12 and hexagonal block 21, and one side of hexagonal block 21 is fixedly connected with hollow hemispheroid 22, and rust is prevented in threaded hole 25 by hollow hemispheroid 22.

[0022] One end of bolt is connected in threaded mode through the penetration of round hole 13 and the clamping groove 24 on hexagonal block 21, and when hexagonal block 21 rotates, arc plate 11 is driven to rotate, and the other end of arc plate 11 and hexagonal block 21 is close to bolt.

[0023] The other side of arc plate 11 is fixedly installed with gasket 15, and the protection of arc plate 11 is carried out through gasket 15, when support component 1 extrudes the object, the abrasion of arc plate 11 is reduced through gasket 15 protection arc plate 11, and the service life of arc plate 11 is prolonged.

[0024] Taking into account that in the process of the polygonal wrench being turned to the hexagonal block 21, because there is a gap between the polygonal wrench and the side wall of the hexagonal block 21, when the polygonal wrench drives the hexagonal block 21 to rotate, the polygonal wrench will rub the corners of the hexagonal block 21, so that the corners of the hexagonal block 21 are ground flat. After the corners of the hexagonal block 21 are ground flat, it will be difficult to remove the hexagonal block 21 from the bolt. In order to solve this problem, a plurality of fixing bars 14 are fixedly installed in the hexagonal groove 12, and the fixing bars 14 are all located in the middle position of the inner wall of the hexagonal groove 12. The six faces of the hexagonal block 21 are provided with card slots 24, and the fixing bars 14 are clamped in the card slots 24, and when the fixing bars 14 are clamped in the card slots 2 4, one side of the fixing bar 14 extends outward, so that a height difference is formed between the side wall of the hexagonal block 21 and one side of the fixing bar 14, and a right-angled surface is formed between the side wall of the fixing bar 14 and the side wall of the hexagonal block 21. When the polygonal wrench needs to rotate the nut assembly 2, the polygonal wrench will contact the side wall of the fixing bar 14. When the polygonal wrench rotates, the polygonal wrench rubs against the side wall of the fixing bar 14 and the corners of the hexagonal block 21, so that the bracket assembly 1 and the nut assembly 2 are rotated. By increasing the contact area between the polygonal wrench and the hub cap nut, the degree of wear of the polygonal wrench on the corners of the hexagonal block 21 is reduced, thereby ensuring the normal use of the hexagonal block 21.

[0025] When using the low-torque and high-efficiency hub cap nut of this embodiment, first take out the special polygonal wrench and insert it along the hexagonal block 21 and the fixing bar 14. At the same time, the contact area is increased under the action of the fixing bar 14 to ensure that it will not slip during rotation. Rotate the hexagonal block 21 clockwise to remove it. When the threaded hole 25 in the hexagonal block 21 is stripped, it can be removed and replaced along the hexagonal groove 12 and the fixing bar 14.
