Background

The special protective vehicle refers to a special purpose vehicle with the aspects of overall dimension, weight and the like exceeding the design vehicle limit, and is provided with fixed equipment after being specially manufactured or specially modified.

The special protection vehicle is generally based on a common vehicle, and achieves a special protection function by additionally arranging a hanging armor on a vehicle body. The vehicle body frame and the hanging armor are fixedly connected with each other through bolts and welding nuts, so that the hanging armor and the vehicle body frame are fixedly installed. However, all the welding nuts in the market do not have the function of preventing the breakdown of the bullet, and the through hole for connecting the bolt and the welding nut on the hanging armor becomes a weak point for protection, and an additional armor protection structure needs to be added, so that the structure of the vehicle body is complex and the weight is increased.
