the labels in the figure are: 1. gasket body, 2, first circular convex block, 3, second circular convex block, 4, triangle-shaped arris piece.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example 1
As shown in fig. 1: the utility model provides a can prevent memory alloy gasket that nut convoluteed, the material of alloy gasket is nickel titanium copper alloy, and the gasket includes gasket body 1, and the top of gasket body 1 is outer evenly to be provided with six first circular convex blocks 2 along its circumference along the edge, evenly is provided with six second circular convex blocks 3 along its circumference in the bottom of gasket body 1 along the edge. The first circular bumps 2 and the second circular bumps 3 are arranged in a staggered manner at the circumferential positions.
The memory alloy gasket is sleeved on the bolt which is arranged in the bolt hole in a penetrating mode, at the moment, a concave end (namely the bottom end in the view) of the memory alloy gasket is in contact with a part surface to be fixed, then the nut is screwed (at the moment, a convex end (namely the top end of the memory alloy gasket faces the nut), in the process of screwing the nut, the first round convex block 2 and the second round convex block 3 can respectively rub the nut and the part, the nut is screwed until the nut flattens the memory alloy gasket, and after the memory alloy gasket is flattened, the nut stops rotating.
When the surface temperature of the memory alloy gasket reaches 45 ℃, the memory alloy gasket can begin to restore the deformation of the initial state, the convex end of the memory alloy gasket can prop against the nut in the process, the nut is provided with a force along the axial direction of the bolt, the friction force between the bolt and the thread of the bolt is increased, and the looseness prevention of the nut is facilitated.
Example 2
As shown in fig. 2: the utility model provides a can prevent memory alloy gasket that nut convoluteed, the material of alloy gasket is nickel titanium alloy, and the gasket includes gasket body 1, and the top of gasket body 1 is outer along the edge evenly be provided with eight triangle-shaped arriss pieces 4 along its circumference, and triangle-shaped arris piece 4 is transversal personally submitted right triangle-angled triangle. The long side of the triangular prism block 4 is in the same direction with the rotation direction of the nut.
The memory alloy gasket is sleeved on the bolt which is arranged in the bolt hole in a penetrating mode, at the moment, the concave end (namely the bottom end in the view) of the memory alloy gasket is in contact with the surface of a part to be fixed, then the nut is screwed (at the moment, the convex end (namely the top end of the memory alloy gasket faces the nut), in the process of screwing the nut, the nut rotates clockwise along the long edge of the triangular prism block 4, the nut is screwed until the nut flattens the memory alloy gasket, and after the memory alloy gasket flattens, the nut stops rotating.
When the surface temperature of the memory alloy gasket reaches 45 ℃, the memory alloy gasket can begin to restore the deformation of the initial state, the convex end and the triangular prism block of the memory alloy gasket can prop against the nut in the process, the nut is provided with a force along the axial direction of the bolt, the friction force between the bolt and the thread of the bolt is increased, and the looseness prevention of the nut is facilitated.
The foregoing description of the specific embodiments of the invention has been presented.
