secondly, the anti-drop base provided by the utility model has better anti-drop performance, can fasten the base of the bolt anti-corrosion protection device, can prevent the bolt anti-corrosion protection device from rotating under the vibration caused by strong wind or train passing, and prevent the bolt anti-corrosion protection device from dropping, thereby preventing the bolt anti-corrosion protection device from dropping to cause railway traffic safety accidents;
thirdly, the anti-drop base provided by the utility model has better sealing performance, can isolate the bolt and the nut from the outside, prevents air and moisture from entering, prevents the bolt and the nut from being rusted, and protects the bolt and the nut from safe and reliable operation; the bolt has the function of blocking water and air from entering, thereby achieving the effects of corrosion prevention and rust prevention of the bolt;
fourthly, the anti-drop base provided by the utility model has more stable fastening effect, can fasten the bolt anti-corrosion protection device and the like, and enables the bolt anti-corrosion protection device to be tightly and firmly combined with the nut and the bolt, thereby avoiding falling off under the action of external force;
fifth, the anti-drop base provided by the utility model can be repeatedly used for many times, and has long service life; the bolt can be conveniently detached, the cost is reduced, the overhauling speed is accelerated, and meanwhile, the safety of the structure is ensured;
sixth, the utility model provides an anticreep base, it is rational in infrastructure for the site operation installation is comparatively simple and convenient, save time and save labour, and the appearance is comparatively pleasing to the eye, still has advantages such as sun-proof, anticollision.
