In order to solve the above problems, a rubber pad 3 is additionally provided, and the rigid connection between the band 2 and the air cylinder 1 is changed into a flexible connection by the elastic restoring force of the rubber pad 3.
Specifically, the rubber pad 3 is clamped between the clamping band 2 and the air cylinder 1, wherein the inner side surface 301 of the rubber pad 3 is attached to the outer circumferential surface of the air cylinder 1 to form a butt joint, and the outer side surface 302 of the rubber pad 3 is detachably connected with the clamping band 2.
Cushion 3 adopts elastic material to make, and cushion 3 separates strap 2 and gas receiver 1 two to form the elasticity butt with strap 2 and gas receiver 1 respectively, so, because cushion 3's elastic deformation, the flexible connection mode after the improvement has the buffering effect, can alleviate because the vibration of gas receiver 1 that the road surface unevenness arouses, has avoided the strap 2 fracture that the vibration leads to, has prolonged the life of strap 2. In addition, the rubber cushion 3 can also prevent the shell of the air storage cylinder 1 from being scratched due to the direct connection of the air storage cylinder 1 and the strap 2.
In the present embodiment, Ethylene Propylene Diene Monomer (EPDM) is preferably used as the rubber pad 3. EPDM is a copolymer of ethylene, propylene and a small amount of non-conjugated diene, is one kind of ethylene-propylene rubber, because its main chain is composed of chemically stable saturated hydrocarbon, only contains unsaturated double bond in the side chain, so it has excellent ozone resistance, heat resistance, weather resistance and other aging resistance, and can be widely used in the fields of automobile parts, building waterproof materials, wire and cable sheaths, heat-resistant rubber tubes, adhesive tapes, automobile sealing parts and the like.
