Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative 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.

As shown in fig. 1-2, a polyurethane foam pad with strong cushioning property is provided, which comprises an upper layer 1 and a lower layer 2, wherein the bottom of the upper layer 1 is connected with the lower layer 2, and the upper layer 1 and the lower layer 2 are symmetrically arranged;

an upper buffer strip 102 is arranged on the inner side of the upper layer 1, and an upper buffer column 103 is arranged inside the upper buffer strip 102;

the inside of lower floor 2 is provided with lower buffering strip 201, and the inside of lower buffering strip 201 is provided with lower cushion column 202.

Set up buffer strip 102 and lower buffer strip 201 on upper 1 and lower floor 2, it sets up to crisscross again between buffer strip 102 and the lower buffer strip 201, thereby make the inner wall of upper 1 and lower floor 2 all with the top contact of buffer strip 201 and last buffer strip 102 down respectively, consequently when taking place the vibration or when assaulting, utilize buffer strip 102 and the energy absorption of buffer strip 201 with the vibration down, and transmit in its inside last bumping post 103 and lower bumping post 202, eliminate the vibration, avoid vibrating too big structure damage that leads to.

In this embodiment, be provided with between upper 1 and the lower floor 2 and be connected sealing strip 101, connect the both ends of sealing strip 101 and connect the inboard at upper 1 and the opposite face of lower floor 2, seal strip 101 through setting up the connection between upper 1 and lower floor 2 to seal strip 101 through connecting and couple together upper 1 and lower floor 2, guaranteed the steadiness of connecting between upper 1 and the lower floor 2, improved the reliability of device, avoid appearing the circumstances such as drop between the structure, improved the stability of device.
