Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a thread-shaped gasket as shown in the figure, which comprises a thread-shaped gasket 1, a connected piece 2 and a bolt 3, wherein one end of the bolt 3 is in threaded connection with the thread-shaped gasket 1, and one end of the bolt 3 is in threaded connection with the connected piece 2, and the thread-shaped gasket is characterized in that: the spiral shell shape packing ring 1 comprises the spirochaeta 11 of panel beating screw thread, the supporter 12 of panel beating screw thread, arc 13, screw thread technology breach 14 and dish flange 15, 11 one side of the spirochaeta of panel beating screw thread is provided with the supporter 12 of panel beating screw thread, 12 one side of the supporter of panel beating screw thread are equipped with arc 13, dish flange 15 is connected in the 13 outside of arc, 1 middle part diagonal of spiral shell shape packing ring is equipped with screw thread technology breach 14.
Furthermore, in the above technical solution, according to the requirement of the fastener anti-loose elasticity, a plurality of thread process notches 14 can be uniformly distributed along the circumference of the arc-shaped body 13;
furthermore, in the above technical solution, in order to change the elasticity of the dish-shaped flange 15, process slots can be uniformly distributed on the circumference of the dish-shaped flange 15 avoiding the thread process gap 14;
further, in the above technical solution, a counter bore 21 is arranged at the top of the connected piece 2, a bolt hole 23 is arranged in the middle of the connected piece 2, and the upper end of the bolt hole is connected with an inner chamfer surface 22;
