(III) beneficial effects
The invention provides a shock absorption support, wherein an adjusting plate is arranged between an upper shock absorber and a lower shock absorber and comprises a supporting part. When the upper support is uniformly loaded, the upper shock absorber and the lower shock absorber can absorb shock normally. When the upper support is loaded by the unbalanced load, the upper shock absorber and the lower shock absorber start to compress from the working length, and as the supporting part is positioned on the periphery of the lower shock absorber, one end of the unbalanced load of the supporting part contacts the lower support before the upper shock absorber and the lower shock absorber compress to the bearing length. This gives the upper damper a supporting force so that the upper support is decelerated and the upper support is offset by a shorter distance from the original position than when the supporting portion is not provided. And then continues to compress the upper damper to the load-bearing length. Meanwhile, the other end of the supporting part is in a tilting state, the supporting part integrally rotates and presses down by taking one end of the unbalanced load as a fulcrum, a movement space is provided for the upper shock absorber, and the vibration of the upper support is continuously slowed down. The shock pad can alleviate the impact when the support portion contacts the lower support. The invention can better maintain the posture when bearing the unbalanced load and effectively see the shock absorption. Meanwhile, the shock absorption effect on abrupt load is good, the upper shock absorber and the lower shock absorber move asynchronously, the vibration of a part of the upper support is absorbed into the suspended adjusting plate, and the time delay is transmitted to the lower support.
The spring or the rubber pad can provide elastic force in the vertical direction and can bear certain shearing and torsion force. The upper and lower shock absorbers are fixedly connected with the lower support or the upper support or the adjusting plate for better restraining the working position.
The axis positions of the components of the embodiment coincide, which is beneficial to improving the stability of the upper support when uniform load is applied.
The plurality of upper shock absorbing members and the lower shock absorbing members are evenly distributed to provide shock absorption, so that the bearing area can be increased, the bearing capacity can be improved, and the device is suitable for different use environments.
The stability of the upper support can be better maintained by adding the supporting shock absorber, the pressing gesture of the upper support after being loaded is optimized, and the change curve of the displacement of the upper support is optimized.
Also, the support damper is fixed to maintain its working position better. And the axis of the bearing is overlapped with the axis of the upper support so as to improve the stability of the swing direction of the upper support.
The safety rubber can provide a buffer for the main body of the adjusting plate when the supporting part bottoms out, which is helpful for protecting the upper shock absorber.
The annular supporting part can be uniformly adapted to unbalanced load in different directions.

Detailed Description
The invention will be better explained by the following detailed description of the embodiments with reference to the drawings.
Example 1
As shown in fig. 1 and 2, a lower support 2, a lower spring set 6, an adjusting plate 3, an upper spring set 4 and an upper support 1 are sequentially arranged from bottom to top, and a supporting spring set 5 is also directly connected between the lower support 2 and the upper support 1. The adjusting plate 3 includes a supporting portion extending downward, as shown in fig. 2, the supporting portion is a ring-shaped supporting ring 32, and a rubber pad 31 is further provided on the bottom surface of the supporting ring 32.
The upper support 1 and the lower support 2 are two square supports which are placed in an aligned mode, the outer ring of the adjusting plate 3 is circular, and the corresponding supporting ring 32 is a circular ring. The outer ring of the adjusting plate 3 may be polygonal or square in nature, and the support ring 32 may be non-circular, with its ability to resist uneven load in different directions being different. The support ring 32 may be discontinuous, such as a ring of support columns arranged in series.
The axes of the upper support 1, the lower support 2 and the adjusting plate 3 in the vertical direction are coincident with a vertical line. In fig. 2, the upper spring set 4 and the lower spring set 6 are all uniformly distributed along the vertical line by four uniformly distributed spring elements, and the spring elements are shock absorbing pieces, equal heights, rubber and the like. The upper spring group 4 is an upper shock absorber, and the lower spring group 6 is a lower shock absorber. The upper and lower shock absorbers may also be individual springs, rubber or other shock absorbers that provide for longitudinal and circumferential elastic movement.
The supporting spring group 5 is used for supporting the shock absorber and is also composed of uniformly distributed supporting shock absorbing pieces. The supporting shock absorbing members in the figure are uniformly distributed outside the adjusting plate 3, or the supporting plate 3 body can comprise a vertical through hole, and one or more supporting shock absorbing members are arranged in the through hole to form a supporting shock absorber.
In practice rubber pad 31 may be a ring of closely spaced springs positioned along support ring 32. Which acts as a shock pad for the support ring 32. The rubber pad 31 cannot be compressed in a short shock-absorbing stroke, i.e., a short stroke, but has a large load-bearing capacity. The shock pad may also be provided on the top surface of the lower support 2 at a position corresponding to the support ring 32.
As shown in fig. 1, the distance between the bottom surface of the rubber pad 31 and the top surface of the lower support 2 is smaller than the damping stroke of the lower spring set 6, i.e. when the lower spring set 6 has not been compressed to the limit position, the supporting ring 32 is already under the action of the lower support 2 and cannot descend, but can also descend a little more than the damping stroke of the rubber pad 31.
After the assembly of the present embodiment, the upper spring set 4, the support spring set 5 and the lower spring set 6 are compressed from a natural length to a working length. The damping stroke of the supporting spring set 5 is longer than the sum of the damping lengths of the upper spring set 4 and the lower spring set 6.
When the upper support 1 is uniformly loaded, the pressure is borne by the upper spring group 4, the supporting spring group 5 and the lower spring group 6, and the upper spring group, the supporting spring group 5 and the lower spring group are compressed to the bearing length. When the load is excessive, the adjusting plate 3 is supported by the lower support and cannot be lowered further. The shock is also absorbed by the three spring groups, and the adjusting plate 3 is in a suspended state. When vibration waves are transmitted from the upper part, the vibration waves are firstly absorbed by the inertial motion of the adjusting plate 3 and then slowly transmitted to the lower part. When the amplitude is too large, the short impact and recoil of the supporting ring 32 and the lower support 2 can slow down the movement amplitude of the upper support 1, so that the posture of the upper support 1 is maintained better. And possible resonances can be damped.
When the upper support 1 is loaded by offset load, the upper spring group 4 and the lower spring group 6 start to compress from the working length, and when the load is smaller, the whole posture of the embodiment is similar to that when the load is uniformly distributed; when the load is large or the vibration repeating is large, the support ring 32 is positioned at one end of the unbalanced load, and contacts the lower support 2 before the upper spring set 4 and the lower spring set 6 are compressed to the bearing length. This gives the upper spring set 4 a sudden recoil force which slows down the upper support 1 and maintains the upper position for a longer period of time, the overall attitude of the upper support 1 being better, and as the load continues to increase, the upper spring set 4 continues to compress to the load-bearing length. Meanwhile, the other end of the supporting ring is in a tilting state, the whole adjusting plate 3 rotates and presses downwards by taking one end of the unbalanced load as a fulcrum, more movement space is provided for the upper spring group 4, and vibration of the upper support is continuously slowed down.
Example 2
As shown in fig. 3, the upper bumper is a rubber pad including a protruding dome. The top surface of the adjusting plate 3 comprises a concave surface matching the rubber pad. Thus, when the upper support 1 is subjected to an unbalanced load, the adjusting plate 3 is not horizontal any more but is angled to the upper support 1, the concave surface can be more vertical than the direction of the supporting force provided by the plane.
Example 3
As shown in fig. 4 and 5, the supporting ring 32 is connected with the body of the adjusting plate 3 through the safety rubber 33, the compression stroke of the safety rubber 33 is extremely short, and the overall rigidity of the adjusting plate 3 is not affected. When the upper support is overloaded by force and the upper spring set 4 is compressed to the limit, the supporting ring 32 is supported on the lower support 2, the body of the adjusting plate 3 can further descend relative to the supporting ring 32, and even cut or stretch-break the safety rubber, so that the upper support 1 has a certain descending space, the probability of overall damage after overload in the embodiment is reduced as much as possible, and the embodiment can further provide a certain bearing and damping effect.
The above embodiments are merely preferred embodiments of the present invention, and those skilled in the art should not understand the present invention to limit the scope of the present invention, which is defined by the claims.
