Apply a trace amount of self-coagrating resin to the cap of the fixing screw and then tighten it to increase the friction that prevents the screw from reversing.
Increase friction. The screw cap is also called a nut, and the bolt and nut are through the helix that both of them have.
Connected. Through the spiral, the spiral motion of the nut is turned into a linear motion along the axis of the bolt. The coupling is tightened and removed by tightening and loosening the screws.
Why do screw caps be made in a regular hexagon? Because the honeycomb is a structure that perfectly combines growth and expansion. The expansion of the honeycomb is the most delicate and can withstand the enormous external pressure, which is offset by the sharing of acceptance. Bees are queen bees.
center, clockwise.
Around the establishment of countless tightly knit hives. When the worker bees build their nests, they will complete each chamber at the same time, and the walls of each chamber are shared with the neighboring chambers, so the most economical material is not too heavy, and its shape is gravity.
Under the effect of the natural formation of the hexagon, to achieve the most material-saving and strong structure in the building.

Answer: In order to prevent falling off, you can put a hard rubber pad, tighten it hard, it is no longer easy to fall off, if the metal surface is fastened, you can put a spring pad, and it is not easy to fall off if you tighten it hard.

If you have a large amount of space, you can consider using a piece of metal to weld the edge of the nut to the machine, and you can also drill a hole in the screw and get the nut stuck in the range of the screw!

3. The cotter pin is to play the role of fixing the screw, but in the process of mechanical movement, the pin may be damaged in this method, the screw nut is easy to wear, the ring screw is broken, it is easy to cause the screw and the screw tooth to slip the wire, and the screw anti-loosening performance is unstable. 4. Double nut - use tightening force to make the double nut achieve the anti-loosening effect and increase.

Answer: There are many causes of automatic falling off of bolts, but they can be mainly summarized as falling off with the vibration or inertia of the component after loosening. The reasons for loosening may be:
1. The sequence of fastening of the components is not scientific, and the stress of other bolts and loose bolts is uneven, which leads to the reduction of the force transmission friction surface, and the bolt is small in the bolt hole.
-
The purpose of studying the tightening torque of high-strength bolts is to determine the tightening torque of the bolt when it is in use, because the use of installation is that if the tightening torque is small, loosening failure will occur under the action of high-strength load, and if the tightening torque is too large, the axial tension generated by the torque will exceed the yield strength of the material, which will lead to the fracture of the bolt.

It is best to clamp the screw with pliers.
-
With a pair of scissors or whatever, you can clamp the screws and turn them upwards while twisting them.
-
If it is a small screw, you can make a groove in the screw head and unscrew it out with a slotdriver; If it is a larger screw on the equipment, the nut can be welded.

Hello, dear, I am glad to answer for you: bolt removal anti-falling A: dear, hello, 1
Flattening washer - increase the contact area, reduce the pressure, and prevent loosening, but this method disassembles frequently, and is limited to preventing the loosening of small screws, and can not play a strong role in preventing screw loosening2White lock nut - is self-locking by friction, so that it can prevent, the relative rotation of the nut and the bolt, play the role of the screw to prevent loosening, the disadvantage is its high cost. 3..
The cotter pin ——— plays the role of fixing the screw, but in the process of mechanical movement, the pin may be damaged in this method, and the screw nut is easy to wear, destroys the screw tooth, and easily causes the screw and the screw tooth to slip and slowly bury the wire, and the screw anti-loosening performance is unstable. 4.Double nut - the use of tightening force to make the double nut achieve the effect of anti-loosening, increase the weight, only limited to the relatively weak loosening, and can not play a strong role in preventing loosening, the actual use is improper, can not play the role of anti-loosening, the anti-loosening performance of the screw is unstable.
5.Locking is one of the more traditional anti-loosening methods, which is widely used in aircraft-related fields, however, in this method, the locking thread may be damaged, and the scope of use is limited. Type nut - change the shape of the nut, directly destroy the nut body, indirectly destroy the bolt teeth, and eventually cause the bolt to fall off, and the screw anti-loosening performance is unstable.
7.Sealing tape - leak-proof and not loose, the resistance to the lock is large, and the anti-loosening performance is unstable in the process of connecting the screw and the nut. The above are several types of methods to deal with loose screws, although they all have certain effects, but the disadvantages are also obvious.
At this time, it is better to consider the screws of Oudili Hardware, which can use the reaction force of raw materials to make bolts and nuts reach absolute resistance to vibration and impact through extrusion during the locking process, and can be disassembled and reused, so that the screws have the effect of anti-loosening and leakage-proof. Screws can significantly improve production efficiency, reduce production costs, and can be used in a wide range of applications, and can be processed with screws of any shape; Light weight, no rust; It can be disassembled and used repeatedly; The anti-loosening performance of the screw is stable, and it is an excellent anti-loosening screw product. Thank you for your patience.
The above is my full reply, if you are satisfied with my service, please give a thumbs up, and I wish you all the best! Peace and joy!

The following methods can be used:
1. The screw glue can effectively bond the screws to prevent loosening.
2. The spring washer is adopted, which can increase the contact pressure and thus increase the friction and prevent loosening.
3. Regularly check if there is any looseness, tighten it in time.
It is very important to interpret the dream of tooth loss in the context of your entire dream, which has different meanings for the same episode. Because there are only fragments, I can only give you some hints: when you dream of loose or falling teeth, you should first see if there is really something wrong with your teeth, maybe the teeth are slightly loose and you don't pay attention during the day, so your subconscious mind reminds you in the dream. >>>More
