Problems solved by technology
For this type of device, one is that the mechanical device is prone to loosening during work or over time or by external influences. For example, the bolts and nuts used to fix the motor will have a certain displacement under the vibration of the motor. And it will become more and more serious, and finally cause the nut to fall off
Second, the fasteners of bolts and nuts are easily exposed to complex environments and cause rust, which is not conducive to their service life and fastening effect

Embodiment Construction
[0014] In order to describe the technical solutions provided by the present invention in detail, the specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.
[0015] Such as figure 1 As shown, a bolt kit includes a bolt 1, a nut 2, a heating hole 3, a cap 4 and an anti-loosening device 5, the top of the bolt 1 has a heating hole 3, and the opening end of the heating hole 3 is provided with a connecting thread of the cap 4 , and the thread is opposite to the nut installation thread. When the nut is installed clockwise, the thread of the cap 4 is installed in the opposite direction, so as to avoid the cap 4 and the nut 2 from falling off due to the installation in the same direction. If it is set in this way, it will also be installed after fixing They can act as a hindrance to each other and restrict the loosening phenomenon.
[0016] After the bolt 1 and the nut 2 are installed and fixed, a heatin...

The invention discloses a bolt external member and a connecting anti-loosening method thereof. The top of a bolt is provided with a heating hole used for rising or reducing the temperature of the bolt, and the top of the bolt is further provided with a cap and an anti-loosening device. When the external member of the bolt is used, the external member consisting of the bolt and the nut is fastenedby utilizing the principle of expansion caused by heat and contraction caused by cold, so that the problem of loose connection is prevented. According to the invention, the bolt and the nut are uniformly stressed and cannot be permanently damaged. The principle of expansion caused by heat and contraction caused by cold is also utilized for dismounting of the bolt, the dismounting of the bolt is convenient after the bolt is expanded caused by heating, and therefore, the bolt external member is convenient to mount and dismount and is uniform in stress.
Description
technical field [0001] The invention belongs to fasteners, in particular to a bolt set and a connection and anti-loosening method thereof. Background technique [0002] In mechanical fastening, the most common technology is to install or fix the mechanical structure through the fixing of bolts and nuts. Mechanical fasteners are basically tightened and fixed by mechanical hydraulic wrench to achieve the loosening effect. For this type of device, one is that the mechanical device is prone to loosening during work or over time or by external influences. For example, the bolts and nuts used to fix the motor will have a certain displacement under the vibration of the motor. And it will become more and more serious, and finally cause the nut to fall off. The second is that the fasteners of bolts and nuts are easily exposed to complex environments and cause rust, which is not conducive to their service life and fastening effect.
