Abstract
The invention relates to the field of mechanical equipment, in particular to a self-tightening nut capable of preventing a bolt from loosening. A nut spare of fastening bolt that relates to, its characterized in that: the nut fastener has a curved bar; one end of the curved bar is provided with a thread; the thread teeth are in contact with the thread of the bolt, the top end of the curved bar is provided with a tip, and the height of the tip is slightly higher than that of the end face of the nut; after the nut fastens the bolt, the thread tooth of the curved bar is extruded by the thread of the bolt, the top of the curved bar is extruded by the connecting piece, the thread of the bolt is clamped, and the nut is prevented from rotating; the nut has the characteristics of convenience in installation, high efficiency and high reliability, and can be used on high-vibration equipment. The self-tightening nut is simple in operation process, firstly, a curved bar is installed by the nut (the curved bar is smeared with grease or generates frictional substances), and the nut is tightened until the curved bar is tightly pressed. Because the upper end of the curved bar is slightly higher than the end surface of the nut, the curved bar is stressed to clamp the thread of the bolt, and the nut is prevented from rotating, so that the effect of fastening the bolt by the nut is achieved.
Description
Technical Field
The invention relates to the field of mechanical equipment, in particular to a looseness-preventing self-tightening nut.
Background
In the mechanical equipment assembling process, a plurality of parts are assembled and connected by bolts and nuts; when the equipment runs, the nut and the bolt are loosened due to vibration; the loose nut and bolt cannot effectively control the operation of equipment, so that great potential safety hazards are brought, and the maintenance cost is increased by manually tightening the nut; common nuts and bolts are tightened by thread extrusion and friction force, the effect is poor, and the due effect cannot be well played; and the rigid structure between the bolt and the nut generates mechanical interaction force, so that the bolt and the nut are easy to loosen.
Disclosure of Invention
The invention aims to provide a fastener, and relates to a self-tightening nut for preventing a bolt from loosening
The invention adopts the following technical scheme for achieving the purpose:
the invention aims to solve the problem of loosening of bolts and nuts, and provides an anti-loosening technology, so that the problem of loosening of the bolts and the nuts caused by high-strength vibration of equipment is effectively solved.
In order to achieve the purpose, the purpose of the invention is realized by the following technical scheme:
the utility model provides a prevent that bolt and nut is not hard up device which characterized in that includes: a curved hole nut and a curved rod.
The nut with the curved hole is provided with a curved hole, and is characterized by being a section of a circular ring in shape; the inlet of the curved hole nut is arranged on the upper end surface of the nut, the outlet of the curved hole nut is arranged at the thread of the inner hole of the nut, and the curved hole ensures that the curved rod slides back and forth; the curved bar is arranged in a curved hole of the curved hole nut, and one end of the curved bar is provided with a thread tooth which is combined with the thread of the curved hole nut; the other end of the curved bar is provided with a tip slightly higher than the end surface of the nut with the curved hole; the curved rod and the curved hole of the curved hole nut are both of a section of structure of a part of a circular ring.
According to the anti-loosening fastening nut, the nut fastening piece is provided with the bent rod, so that the nut and the bolt thread are prevented from sliding; and the design and installation are simple, the operation is convenient, the performance is reliable, and the device is suitable for installation of various devices.

In the figure: 1. the device comprises a curved hole nut 2, a curved rod 3, a bolt 4, a connecting piece 5, a curved hole 6, a thread tooth 7 and a tip.
Detailed Description
The invention is described in connection with the accompanying drawings and the specific embodiments:
as shown in fig. 1, in combination with fig. 2, 3 and 4, a self-tightening nut for preventing loosening, the nut fastener having a curved rod; the curved bar is arranged on the curved hole nut, and one end of the curved bar is provided with a thread; the thread teeth are in threaded contact with the bolt, the top of the upper end of the curved bar is provided with a tip, and the height of the tip is slightly higher than that of the end face of the nut; after the nut fastens the bolt, the thread tooth of the curved rod is extruded by the thread of the bolt, the top of the curved rod is extruded by the connecting piece, the thread of the bolt is clamped, and meanwhile, the nut is prevented from rotating.
Finally, it is noted that the above preferred embodiments are merely intended to illustrate rather than to limit the invention, and that, although the invention has been described in detail with reference to the above preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims.
