The gravity center of the parcel box 24 is positioned at the lower half part of the circle center of the inner ring 23, the outer ring 21 is parallel to the bottom surface of the protection cabinet 1, after the parcel box 24 is placed in an instrument, the gravity of the parcel box 24 is increased, because the inner ring 23 is connected with the outer ring 21 through the spherical slide rod 8, the inner ring 23 can slide in the outer ring 21 and can rotate around the central line where the spherical slide rod 8 is positioned, the inner ring 23 is always vertically pointed to the ground under the action of gravity, and therefore when the protection cabinet 1 is turned on one side, the internal instrument is also in an original state, and the parts in the instrument cannot fall off due to the fact that the internal part is turned on one side.

Example two

Referring to fig. 2, a vehicle-mounted damping device for carrying multi-directional anti-vibration precision instruments includes a protection cabinet 1, the protection cabinet 1 further includes a multi-directional damping mechanism 3, a fixed frame 31 is disposed inside the multi-directional damping mechanism 3, four groups of the multi-directional damping mechanism 3 and four groups of damping rods 7 are disposed inside the fixed frame 31, and the four groups of the damping rods are distributed at four corners of the fixed frame 31, and the other end of the fixed damping rod 36 away from a damping axis 34 is connected to an inner wall of the protection cabinet 1. The lower extreme swing joint of fixed frame 31 has protection gasbag 5, and the left and right sides of fixed frame 31 all is provided with location loop bar 4, and the outside swing joint of fixed frame 31 has connecting block 32, and the outside swing joint of connecting block 32 has horizontal spring beam 33, and the one end swing joint that horizontal spring beam 33 kept away from connecting block 32 has buffering axle center 34, and the lower extreme swing joint of buffering axle center 34 has vertical spring beam 35, and the upper end swing joint of buffering axle center 34 has fixed buffer beam 36.

The impact that can eliminate under the effect of protection gasbag 5 and transmit the protection cabinet 1 bottom, reduce rocking that fixed frame 31 itself takes place, and when protection cabinet 1 takes place to rock, because the outside at fixed frame 31 is provided with horizontal spring beam 33, horizontal spring beam 33 is connected with vertical spring beam 35 and fixed buffer rod 36 through buffering axle center 34, the position that fixed frame 31 and protection cabinet 1 back wall are right also is provided with shock attenuation pole 7 simultaneously, when the side position takes place to rock, will rock through fixed buffer rod 36 and transmit the rocking load that transmits for horizontal spring beam 33 and vertical spring beam 35 thereby weaken the side and transmit, combine above, reach and weaken the influence of rocking the external rocking load that transmits in diversified to shaking of instrument body, thereby the protection precision instrument can not take place to rock in the transportation, make its effect undamaged.

The working principle is as follows: when the device is used for transporting a precise instrument, the instrument is firstly placed into a packaging box 24, then a rotary screw 27 is screwed to drive a clamping plate 26 to firmly fix the instrument in the packaging box 24 so as to prevent the instrument from falling off during transportation, a protective sponge 25 is also arranged on the inner wall of the packaging box 24, a primary protective effect can be performed on the instrument, when the protective cabinet 1 turns over during transportation due to unexpected factors such as emergency brake and the like, an outer ring 21 is arranged in a fixed outer frame 31 in the protective cabinet 1, an inner ring 23 is sleeved in the outer ring 21 through a spherical slide rod 8, the gravity center of the packaging box 24 is positioned at the lower half part of the circle center of the inner ring 23, the outer ring 21 is parallel to the bottom surface of the protective cabinet 1, and after the packaging box 24 is placed into the instrument, the gravity of the packaging box 24 is increased, and the inner ring 23 is connected with the outer ring 21 through the spherical slide rod 8, the inner ring 23 can slide in the outer ring 21 and can rotate around the central line of the spherical sliding rod 8, so that the inner ring 23 is always vertically directed to the ground under the action of gravity, and therefore, when the protection cabinet 1 turns over, the internal instruments are also in an original state, and the parts in the instruments cannot fall off due to the fact that the internal instruments turn over.

When bumping, because the bottom of the fixed frame 31 is provided with the protection airbag 5, when the protection cabinet 1 shakes up and down, because the protection airbag 5 has the ability of shrinking up and down, when shaking, the impact transmitted from the bottom of the protection cabinet 1 is reduced and eliminated by the up and down shrinkage of the protection airbag 5, and the shaking amplitude of the fixed frame 31 itself is reduced, when the transportation tool shakes left and right to shake the protection cabinet 1, because the transverse spring rod 33 is arranged outside the fixed frame 31, the transverse spring rod 33 is connected with the longitudinal spring rod 35 and the fixed buffer rod 36 through the buffer shaft center 34, and the shock absorption rod 7 is arranged at the position corresponding to the fixed frame 31 and the rear wall of the protection cabinet 1, when the orientation of the left and right sides of the protection cabinet 1 shakes, the springs surface-mounted on the transverse spring rod 33, the longitudinal spring rod 35 and the fixed buffer rod 36 are used, through the spring, will pass transmission to vertical spring beam 35 and fixed buffer pole 36 that the impact force successive layer that horizontal spring beam 33 weakens to this weakens the load of rocking that transmits from the left and right sides face of protection cabinet 1, reduces the range of rocking about fixed frame 31, combines more than, reaches and rocks the influence in the external world introduced rocking load of leading to the fact of shaking the instrument body in diversified weakening, thereby the protection precision instruments can not take place to rock in the transportation, makes its effect that can be intact.
