Said first rubber member and second rubber member have same structures, including the manganese steel band arranged innermost layer thereof, the nylon layer at the outside of and wrapping the manganese steel band and the rubber layer out of and wrapping the nylon layer, and a plurality of strip-shaped grooves on the oppositely arranged surfaces of said first rubber member and second rubber member.
As an improvement, said first connector comprises a first connecting plate and a second connecting plate which are respectively arranged on two sides of two end portions of the first rubber member and the second rubber member, a first U-shaped piece and a second U-shaped piece are respectively hinged between the first connecting plate and the second connecting plate wherein threaded holes are correspondingly formed in the middle portions of the first U-shaped piece and the second U-shaped piece with bolts arranged in the threaded holes in a matched mode, and said bolts sequentially penetrate through the first U-shaped piece and the second U-shaped piece to be connected and tightened with nut connecting piece.
As an improvement, the tightening torque for connecting and tightening said bolt and the nut connecting piece is at least 10 N*m.
As an improvement, said second connector comprises a third connecting plate and a fourth connecting plate which are respectively arranged on two sides of two end portions of the first rubber member and the second rubber member, and said third connecting plate and said fourth connecting plate are respectively hinged with two ends of the buckle cover through rivets.
As an improvement, said buckle cover comprises a buckle cover bottom plate and buckle cover side plates arranged on two sides of the buckle cover bottom plate, and the buckle cover side plates are arranged on the outer sides of the third connecting plate and the fourth connecting plate.
As an improvement, said buckle cover is an arc buckle cover, and a plurality of through holes are formed in the buckle cover bottom plate.
As an improvement, said through holes comprise strip-shaped through holes and round through holes.
As an improvement, said rivet and the buckle cover are both made of stainless steel materials.
After adopting following structure, the invention has following advantages: the invention, a puncture emergency safety device for automobiles, can save installation space and simplify fixing condition by virtue of oppositely arranged first rubber member and second rubber member; the invention has simple structure and easy to install, and at the same time, possesses function and advantages of rubber air spring and shock absorber which can exert function of bearing, buffering and shock absorbing.
