Abstract
The utility model discloses a damping cushion which comprises an upper connecting plate, a lower connecting plate and a rubber damping block. The rubber damping block is arranged between the upper connecting plate and the lower connecting plate, the cross section of the rubber damping block is circular, a through hole is arranged at the center of the upper connecting plate, a through hole is arranged at the center of the lower connecting plate, and the through hole of the upper connecting plate and the through hole of the lower connecting plate are both communicated with an inner hole of the rubber damping block. The damping cushion is reasonable in structure, saves materials, gives full play to damping properties of rubber viscoelasticity, and has good shock absorption and damping performance.
Description
Technical field
The utility model relates to a kind of damping cushion.
Background technique
At present, elevator etc. are to the equipment of vibration sensing, and all adopting the cross section is circular or rectangular block rubber, and constitutes at both ends of the surface sulfuration connecting plate.During use, the general Rubber shock-absorbing pad that adopts the 2-3 kind hardness specification with same size changes its bearing capacity.During design, the compressive deformation amount of each rubber pad only is controlled in about 5%, fails to give full play to the viscoelastic shock absorbing characteristics of rubber product, has caused the waste of resource.And in the rubber deformation amount hour, its damping constant is less, a little less than the damping capaicty, can make that the passenger's system of Himdu logic in the elevator shows vibrations and causes discomfort.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of damping cushion, and it is rational in infrastructure, can give full play to the viscoelastic shock absorbing characteristics of rubber, has shock-absorbing preferably and damping performance.
The technological scheme that the utility model solves the problems of the technologies described above is: comprise upper junction plate, lower connecting plate and damping rubber block, damping rubber block places between upper junction plate and the lower connecting plate, and the damping rubber block cross section is a ring; The upper junction plate core is provided with through hole, and the lower connecting plate core is provided with through hole, and the through hole on the upper junction plate, the through hole on the lower connecting plate all communicate with the damping rubber block endoporus.
In the above-mentioned damping cushion, described damping rubber block outer wall is provided with a plurality of grooves, and slot cross-section is an arc.
Compared with prior art, the beneficial effect of the utility model is: because the damping rubber block of the utility model adopts the structure of hollow, saved material, practiced thrift cost of material.When the snubber block pressurized, the large-diameter portion of its inner ring branch is squeezed, and causes in radial outward and produces bigger radial force, orders about outer side slot and tends towards stability, and therefore the footpath upwards also absorbs a part of vibration force; The damping rubber block pressurized changes, and the air in the center hole has increased the damping constant of damping cushion, has improved shock-absorbing effect, therefore the utlity model has higher shock-absorbing and damping performance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1; A kind of damping cushion, it comprises upper junction plate 1, lower connecting plate 3 and damping rubber block 2, damping rubber block 2 places between upper junction plate 1 and the lower connecting plate 3; Damping rubber block 1 cross section is a ring; The internal diameter of damping rubber block 2 endoporus 22 intermediate portions is greater than the internal diameter of two end portions, and the outer wall of damping rubber block 1 is provided with three grooves 21, and groove 21 cross sections are arc.Upper junction plate 1 core is provided with through hole 11, and lower connecting plate 3 cores are provided with through hole 31, and the through hole 11 on the upper junction plate 1, the through hole 31 on the lower connecting plate 3 all communicate with the endoporus 22 of damping rubber block 2.
