[0002] There are many kinds of anti-seismic anti-loosening nuts on the market, but the only ones that can really achieve anti-seismic and non-loosening are the "Never Loosening Screws" of the Hard Lock Company of Japan, and the production process of Hard Lock's "Never Loosening Screws" is relatively complicated. , especially the processing of the eccentric cone surface is difficult to control; the present invention is a kind of anti-seismic anti-loosening nut which is relatively easy to process and has better anti-loosening performance; the present invention is one of the two anti-seismic anti-loosening pipe nut structures invented by Wei Boqing , another structure is a top-pressing anti-seismic anti-loosening pipe nut

Embodiment Construction
[0029] exist figure 1 -In the embodiment shown in 9: the snap-on cap type anti-seismic anti-loosening pipe nut includes a compression nut 2 that is in contact with the pressed surface 1 of the nut and a backup nut 7 buckled on the compression nut 2; The compression nut 2 is a hexagonal nut, and its internal thread is a pipe thread structure with one end slightly larger and the other end slightly smaller. The lower part of the compression nut 2 is a hexagonal shape, and the upper part is a cone whose upper and lower sides are not parallel. The pressing surface 3 and the upper end surface of the cone are not parallel and have different inclination angles relative to the vertical line of the central axis, thereby forming a shape in which one side of the central axis of the compression nut 2 is thick and the other side is thin, and the upper end surface 11 of the compression nut is in line with the compression The angle between the vertical line of the central axis of the nut 2 is...

The invention discloses a cap-buckled seismic locking pipe nut which comprises a gland nut and a standby holding nut buckled on the gland nut, wherein the gland nut is a hexagon nut; an internal thread of the gland nut is of a pipe thread structure with one larger end and another smaller end; the lower part of the gland nut is hexagonal; the upper part of the hexagon is a cone of which the upper surface and the lower surface are unparallel; the lower end face of the gland nut and the upper end face of the cone are respectively unparallel to a perpendicular line of an axle wire of the gland nut; the lower end face of the gland nut and the upper end face of the cone are unparallel and are completely consistent in inclined direction; the standby holding nut is a hexagon nut; an internal thread of the standby holding nut is of a pipe thread structure with one larger end and another smaller end; the lower part of the standby holding nut is of an inner conical surface structure; and an included angle between an outer conical surface of the cone at the upper end of the gland nut and the axle wire of the gland nut is equal to an included angle between an inner conical surface of the standby holding nut and an axle wire of the standby holding nut.
Description
technical field [0001] The invention relates to a cap-type anti-seismic and anti-loosening pipe nut, which is suitable for various areas where nuts need to be anti-seismic and anti-loosening, such as connecting nuts for components of moving objects such as high-speed railways, cross-sea bridges, automobiles and locomotives, and belongs to the technical field of fasteners . Background technique [0002] There are many kinds of anti-seismic anti-loosening nuts on the market, but the only ones that can really achieve anti-seismic and non-loosening are the "Never Loosening Screws" of the Hard Lock Company of Japan, and the production process of Hard Lock's "Never Loosening Screws" is relatively complicated. , especially the processing of the eccentric cone surface is difficult to control; the present invention is a kind of anti-seismic anti-loosening nut which is relatively easy to process and has better anti-loosening performance; the present invention is one of the two anti-s...
