It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The first embodiment is as follows: as shown in fig. 1-7, a steady and shock-absorbing lifting platform is characterized in that: comprises a base 1, a supporting plate 2, a spring 3 and a damping block 4; a plurality of brackets 101 are uniformly arranged above the base 1, a sliding hole 102 is formed in the center of each bracket 101, and mounting holes 103 are formed in two sides of each bracket 101; a plurality of sliding rods 201 are symmetrically arranged on the supporting plate 2, the sliding rods 201 are in sliding connection with the sliding holes 102, and the end parts of the sliding rods 201 are provided with damping components 5; the spring 3 is sleeved with the sliding rod 201, one end of the spring 3 is in surface contact with the bottom surface of the supporting plate 2, and the other end of the spring 3 is in surface contact with the upper surface of the support 101; the damping block 4 is clamped with the mounting hole 103, and the damping block 4 is made of butyl rubber; the shock absorption assembly 5 comprises a buffer gasket 501, a limiting sleeve 502 and a protection plate 503; the buffer gasket 501, the limiting sleeve 502 and the protection plate 503 are sequentially arranged at the end part of the sliding rod 201 from top to bottom, and the upper surface of the buffer gasket 501 is in surface contact with the support 101; two side surfaces of the limiting sleeve 502 are respectively in surface contact with the buffer gasket 501 and the protection plate 503; the protecting plate 503 is fixed with the end of the sliding rod 201 by a nut; the buffer gasket 501 is made of natural rubber; one end of the limiting sleeve 502 is symmetrically provided with protrusions 504, the protrusions 504 are in surface contact with the protective plate 503, a plurality of columns 505 are uniformly arranged at the other end of the limiting sleeve 502, and the columns 505 are clamped with the buffer gaskets 501; a round hole 401 is formed in the center of the damping block 4, clamping blocks 402 are symmetrically arranged on one side of the damping block 4, and the clamping blocks 402 are in surface contact with the mounting holes 103; the cross section of the fixture block 402 is trapezoidal; the supporting plate 2 is provided with a reinforcing rib plate 202, and the reinforcing rib plate 202 is of a hollow structure.

When the lifting platform is used, as shown in fig. 1-7, when the parts are placed on the supporting plate 2, under the action of self gravity, downward impact force is easily generated at the moment of contact, and vibration force is generated at the same time, at the moment, the supporting plate 2 compresses the spring 3 and absorbs the impact force and the vibration force at the same time, so that the structure below the lifting platform is prevented from being directly acted, the effect of buffering and absorbing vibration is achieved, and the damping block 4 is arranged on the support 101, so that the vibration force conducted from the joint of the sliding rod 201 and the sliding hole 102 can be damped and absorbed again through material characteristics, and the stability of the bottom structure of the lifting platform is further ensured;

when the heavy object is heavier and exceeds the elastic force of the spring 3, the spring 3 is compressed and cannot reset after the heavy object is placed on the support plate 2, the support plate 2 is pushed to reset under the action of the elastic force of the spring 3 along with the removal of the heavy object, and the buffer gasket 501 is contacted with the lower surface of the support 101, so that the buffer and shock absorption effects are realized, the impact, the vibration and the noise are avoided, and the stability is improved;

when the overload condition occurs, the elasticity of the spring 3 can not support and absorb shock for the heavy object, the end part of the sliding rod 201 can be pushed to be in contact with the base 1, if the direct contact can cause the generation of larger shock force, at the moment, the protection plate 503 is deformed when being in contact with the base 1, the effect of buffering and absorbing shock is achieved, meanwhile, secondary protection is achieved, and the shock force is prevented from being directly acted on the lifting platform; the protection plate 503 is made of spring steel, and thus has a certain elastic deformation.
