It includes a first fixed plate, a second fixed plate on one side of the first fixed plate, and an air bladder between the first and second fixed plates. Connecting blocks are fixed to both ends of the air bladder. The second mounting plate and fourth bolt allow the removal and replacement of the collar, first protective plate, and second protective plate. The first mounting plate and first bolt also decouple the two connecting blocks from the first fixed plate and locking blocks, allowing the user to remove the connecting blocks and air bladder through the extraction cavity for individual replacement. The first flange, second bolt, bracket, and third bolt allow the user to remove the top block first, enabling the installation and removal of the air pipe. Each component of this device can be disassembled individually, facilitating the replacement of damaged parts and enhancing its practicality.

The anti-slip pad 8 provides greater friction between the anti-slip pad 8 and the limiting seat 12, preventing the support springs 14 from reciprocating. The shock-absorbing pad 2 is installed under the base 1. The corresponding protrusions 201 and the insertion grooves 101 make the installation of the shock-absorbing pad 2 and the base 1 more secure, thus preventing the shock-absorbing pad 2 from easily falling off and separating from the base 1, which further improves the performance of the vibration isolation device.
