Problems solved by technology

[0003] Although there are some anti-loosening methods, they are difficult to process and operate.
For example, the method of using nut pads is a more technical solution in this respect. The nut pads used are made of rubber or resin, which is difficult to withstand large repeated shocks, and is not suitable for repeated disassembly or installation.

Embodiment Construction

[0012] The technical solutions of the present invention are described below through specific examples, and the following examples are only for illustrating the present invention rather than limiting the scope of the present invention.

[0013] A kind of anti-loosening firm device, including bolt 1 and nut 2; An internally threaded hole 5 is provided at the end of the bolt 1, and the direction of the internal thread in the internally threaded hole 5 is opposite to the direction of the external thread of the bolt 1; When engaging with the nut 2, the end of the bolt 1 does not exceed the outer end surface of the nut 2; the fastening device also includes a gland 3 with a locking screw 2 fixed in the center, and the locking screw 4 is the same as the end of the bolt. Compatible with internally threaded holes.

[0014] The gland is provided with a circular protrusion with the center of the gland as the center of a circle, and the purpose of the protrusion is to reduce the protrusion...

Abstract

The invention relates to an anti-loosening fastening device. The anti-loosening fastening device comprises a bolt, a nut and a pressing cover, wherein an internal thread hole is formed at the end of the bolt; the internal thread direction of the internal thread hole is opposite to the external thread direction of the bolt; during the joint of the bolt and the nut, the end of the bolt does not extend out of the outer end face of the nut; and a locking screw is fixed in the center of the pressing cover and matched with the internal thread hole at the end of the bolt.

Description

technical field [0001] The invention belongs to the field of firm parts, in particular to an anti-loosening fastening device used in environments with relatively large loads or frequent vibrations. Background technique [0002] The bolt connection method has been widely used because of its simple operation and is suitable for repeated disassembly. However, this connection technology also has certain defects, that is, the nuts are prone to loosening at the place of repeated vibrations with high height and high load. This technical problem has always been difficult for those skilled in the art to overcome. [0003] Although some existing anti-loosening methods are difficult to process and operate. For example, the method of using nut pads is a more technical solution in this respect. The nut pads used are processed from rubber or resin, which are difficult to withstand large repeated shocks, and cannot be used for repeated disassembly or installation. Other ways and methods...
