[0006] An embodiment of the present invention provides an elastic washer fastener. A tongue is provided on the outer edge of the elastic washer toward the convex side of the elastic washer, and the distance between the tongue and the convex surface of the elastic washer is The angle is the first angle, so that when the convex surface of the elastic washer is under pressure, the first angle changes with the change of the pressure on the elastic washer, thereby solving the problem that the tightening torque is not in place and the screw becomes loose and fails. Larger safety risks and technical problems of quality hidden dangers have achieved the technical effect of low-cost and high-efficiency intuitive display of fastener fastening conditions

Abstract
The invention provides a spring washer fastener characterized by comprising a spring washer (1) and one or more tongue pieces (2), wherein the spring washer (1) is a sheet with an inner hole (3), one side of the spring washer (1) is a convex surface, the other side is a concave surface, the tongue pieces (2) are arranged on the outer edge of the spring washer and on the side of the convex surface, the angle formed by each tongue piece (2) and a plane (4) where the outer edge of the spring washer is located is a first angle (5), and when the convex surface of the spring washer is under pressure, the first angle (5) is in negative correlation with the pressure borne by the spring washer (1).
Description
technical field [0001] The invention relates to the mechanical field, in particular to an elastic washer fastener. Background technique [0002] Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. All kinds of fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. Fasteners of this type are called standard fasteners, or simply standard parts. Fasteners are the most widely used basic mechanical parts. [0003] It usually includes the following 13 types of parts: bolts, studs, screws, nuts, self-tapping screws, wood screws, washers, retaining rings, pins, rivets, assemblies and connection pairs, welding nails, wire nuts; washers: the shape is A type of fastener with an oblate ring. Placed between the supporting surface of the bolt, screw or nut and the surface of the connected part, it plays the role of increasing the contact...
