The utility model discloses a further setting: the thickness of the rubber pad is 0.5 cm.
Adopt above-mentioned technical scheme, set up the thickness of rubber pad into 0.5cm, can guarantee that rubber pad thickness is moderate, and it is poor to lead to the fastening effect of shockproof screw when rubber pad thickness is too thick, and when the rubber pad is too thin, can lead to the shock attenuation effect of shockproof screw not enough, and through experimental test show, it is most suitable when the rubber pad thickness is 0.5 cm.
The utility model discloses a further setting: the thickness of the protective sleeve is 0.2 cm.
Adopt above-mentioned technical scheme, through experimental test show, when the thickness of protective sheath is 0.2cm, the thickness of protective sheath is most suitable, and when the thickness of protective sheath was less than 0.2cm, the shock attenuation effect that the protective sheath played was not enough, and when the thickness of protective sheath was greater than 0.2cm, the fastening effect that protective sheath thickness too big can lead to the shockproof screw was poor.
The utility model discloses a further setting: the shockproof nut and the shockproof screw rod are made of high manganese steel ZGMn 13.
Adopt above-mentioned technical scheme: the high manganese steel ZGMn13 has the characteristics of high tensile strength, high toughness, strong impact resistance, strong wear resistance and the like, and the high manganese steel ZGMn13 is used as materials for the shockproof nut and the shockproof screw rod, so that the wear resistance of the shockproof screw can be greatly improved, the shockproof effect of the shockproof screw is improved, and the service life of the shockproof screw can be prolonged.

Fig. 2 is a schematic structural view of a protective sheath in a shockproof screw according to the present invention.
Detailed Description
As shown in fig. 1-2, a shockproof screw comprises a shockproof nut 1 and a shockproof screw rod 2, the shockproof screw rod 2 is provided with threads, the shockproof nut 1 comprises a nut bottom surface 3 fixedly connected with the shockproof screw rod 2 and a nut top surface 4 positioned on the back of the nut bottom surface 3, the bottom surface 3 of the nut is provided with a rubber pad 5 which is matched with the bottom surface 3 of the nut in shape and size, the rubber pad 5 is fixedly connected with the bottom surface 3 of the nut, the rubber pad 5 is provided with a plurality of raised stripes 6, the raised stripes 6 are uniformly distributed on the rubber pad 5, the shockproof screw rod 2 is provided with a protective sleeve 7, the protective sleeve 7 is positioned at the bottom of the shockproof screw rod 2, the inner diameter of the protective sleeve 7 is the same as the outer diameter of the shockproof screw rod 2, the inner side of the protective sleeve 7 is provided with an anti-skid surface 8, and the protective sleeve 7 is detachably arranged at the bottom of the shockproof screw rod 2.
By arranging the rubber pad 5 fixedly connected with the bottom surface 3 of the shockproof nut on the bottom surface 3 of the shockproof nut, when the shockproof screw is connected to equipment to work, the vibration force generated on the equipment is transmitted to the shockproof screw, the rubber pad 5 can play a role of shock absorption, the influence of the vibration force on the shockproof screw is greatly reduced, the vibration force acting on the rubber pad 5 can be uniformly offset by arranging the convex stripes 6 on the rubber pad 5 and uniformly distributing the convex stripes 6 on the rubber pad 5, the further shock absorption effect is achieved, the shockproof capability of the shockproof screw is greatly improved, meanwhile, the abrasion of the shockproof screw is reduced, the service life of the shockproof screw is prolonged, when the equipment vibrates by arranging the protective sleeve 7 on the shockproof screw 2, the vibration force is firstly weakened by the protective sleeve 7, and then is transmitted to the rubber pad 5 through the shockproof screw 2, and is further reduced by the rubber pad 5, therefore, the protective sleeve 7 arranged on the shockproof screw rod 2 plays a role in further shock absorption, meanwhile, the service life of the shockproof screw rod is prolonged, and the anti-slip surface 8 arranged on the inner side of the protective sleeve 7 can increase the friction force between the protective sleeve 7 and the shockproof screw rod 2, so that the protective sleeve 7 is prevented from falling off from the shockproof screw rod 2 when the shockproof screw rod is assembled and disassembled.
The thickness of the rubber pad 5 is 0.5 cm.
Set up the thickness of rubber pad 5 to 0.5cm, can guarantee that rubber pad 5 thickness is moderate, and 5 thickness of rubber pad excessively thick can lead to the fastening effect of shockproof screw poor, and too thin when rubber pad 5, can lead to the shock attenuation effect of shockproof screw not enough, and experimental test shows that 5 thickness of rubber pad are most suitable when 0.5 cm.
The thickness of the protective sleeve 7 is 0.2 cm.
Test tests show that when the thickness of the protective sleeve 7 is 0.2cm, the thickness of the protective sleeve 7 is most appropriate, when the thickness of the protective sleeve 7 is smaller than 0.2cm, the shock absorption effect of the protective sleeve 7 is insufficient, and when the thickness of the protective sleeve 7 is larger than 0.2cm, the fastening effect of the shockproof screw is poor due to the fact that the thickness of the protective sleeve 7 is too large.
The shockproof nut 1 and the shockproof screw rod 2 are made of high manganese steel ZGMn 13.
The high manganese steel ZGMn13 has the characteristics of high tensile strength, high toughness, strong impact resistance, strong wear resistance and the like, and the shockproof nut 1 and the shockproof screw rod 2 which use the high manganese steel ZGMn13 as materials can greatly improve the wear resistance of the shockproof screw, improve the shockproof effect of the shockproof screw and prolong the service life of the shockproof screw.
