Its shock-absorbing mechanism is complex, and the shock-absorbing dense area cannot be adjusted, and the shock-absorbing and noise-reducing effects need to be improved. Utility Model Content

[0005] The purpose of the utility model is to provide a shock-absorbing base for a large circular knitting machine to overcome at least one of the above-mentioned defects in the prior art.

[0016] 1. Since the frame is detachable and the shock-absorbing dense area can be adjusted, the frame installation position can be adjusted according to the maximum vibration and noise transmission area in different situations to ensure the best shock absorption and noise reduction effect.

[0017] 2. The elastic deformation of the flexible pressure block can ensure the filling compactness of the particle damping body, and the flexible pressure block itself in the extruded state can also form a certain buffer, so that the particle damping bodies in the compact filling state can have a more obvious friction energy dissipation effect, so as to reduce the adverse effects on the shock absorption and noise reduction effect caused by the reduction of the filling amount of the particle damping body.

[0018] 3. Through the cooperation of the particle damping body and the frame, a particle damping shock reduction system is adopted. The vibration or noise radiation energy is consumed by the energy consumption of the particle damping body, and the shock absorption and noise reduction effects are good.

[0019] 4. The flexible pressing block is integrated with the top cover, and the flexible pressing block can squeeze the particle damping body while installing the top cover, which is convenient for installation.

[0020] 5. The entire base structure is simple and can achieve good shock and noise reduction effects.

By setting the installation slots distributed in various areas, the required shock-absorbing intensive area is adjusted according to different shock-absorbing requirements, and the best shock-absorbing and noise-reducing effect is achieved with the least frame and particle damping body, without the need to install the frame and particle damping body in each installation slot.

[0022] 7. The flexible constraint bag can maintain the regular force chain network arrangement between the damping particles, and the relative position between the damping particles remains stable under external disturbances; and the collision sound between the damping particles and the frame is extremely weak, which can improve the noise reduction performance.

[0023] 8. The card block and card slot combination makes disassembly and assembly easy.

[0024] 9. The flexible anti-slip mat not only has an anti-slip effect, but also has a certain shock-absorbing effect. BRIEF DESCRIPTION OF THE DRAWINGS
