DETAILED DESCRIPTION

[0017] Reference Figures 1 to 4 As shown, the utility model provides a polyurethane floor vibration damper, comprising: a vibration damping base 1, a vibration damping top plate 2 and a polyurethane floor body 3. The upper end of the vibration damping base 1 supports the polyurethane floor body 3 through the vibration damping top plate 2.

[0018] A support column 22 is welded to the lower end surface of the vibration-damping top plate 2 through a limit plate 21, the inner cavity of the vibration-damping base 1 is fixed to the support column 22 through a vibration isolation block 12, the cavity of the vibration-damping base 1 is connected to the lower cylinder plate 55 of the buffer cylinder 5 through a damping shock absorber 13, the inner side of the buffer cylinder 5 is socketed with the limit plate 21 through a buffer cavity 54, and the upper end of the buffer cylinder 5 is connected to the lower surface of the vibration-damping top plate 2 through a support spring 51.

[0019] First, install the vibration-damping base 1 on the ground or the floor of the car, then fix the limiting plate 21 sleeved on the inner side of the buffer cylinder 5 to the vibration-damping top plate 2, and the limiting plate 21 fixes the supporting column 22 to the vibration isolation block 12 in the cavity of the vibration-damping base 1, and finally, lay the polyurethane floor body 3 on the vibration-damping pad 4 on the upper surface of the vibration-damping top plate 2. When the bottom of the polyurethane floor is vibrated, the vibration amplitude is absorbed and buffered by the damping shock absorber 13, thereby effectively reducing the vibration intensity of the polyurethane floor body 3 at the upper end of the vibration-damping top plate 2.

[0020] In this embodiment, connecting plates 11 are welded to the left and right sides of the vibration-damping base 1 , a vibration-damping pad 4 is bonded to the upper surface of the vibration-damping top plate 2 , and a polyurethane floor body 3 is glued to the upper end of the vibration-damping pad 4 .

[0021] As a preferred embodiment, the shock-absorbing pad 4 facilitates the vibration-absorbing top plate 2 to further fit with the lower surface of the polyurethane floor body 3, thereby reducing the vibration transmitted from the upper end of the polyurethane floor body 3.

[0022] In this embodiment, an upper cylinder plate 53 is welded to the upper end surface of the buffer cylinder 5, and a lower cylinder plate 55 is welded to the lower end surface of the buffer cylinder 5; and the surface of the lower cylinder plate 55 is penetrated and connected with the support column 22. A sealing ring 52 is clamped on the groove surface of the outer end of the upper cylinder plate 53, and the upper cylinder plate 53 is tightly attached to the inner side wall of the vibration-damping top plate 2 through the sealing ring 52. Two rows of support springs 51 are symmetrically connected to the upper surface of the upper cylinder plate 53.

[0023] As a preferred embodiment, the buffer cylinder 5 elastically supports the vibration-damping top plate 2 through the support spring 51 at the upper end of the upper cylinder plate 53, and is connected to the damping shock absorber 13 through the lower cylinder plate 55 at the lower end, so as to buffer and absorb the vibration generated at the bottom, thereby reducing the vibration intensity of the polyurethane floor body 3. The sealing ring 52 prevents the reduction of external water vapor from accelerating the aging of the support spring 51.

[0024] In this embodiment, the lower end of the limiting plate 21 is limitedly connected to the buffer cavity 54 inside the buffer tube 5 , and the limiting plate 21 is screwed and fixed to the lower surface of the vibration-damping top plate 2 .

[0025] As a preferred embodiment, the buffer cavity 54 facilitates the buffer cylinder 5 to move up and down on the surface of the limit plate 21, thereby preventing the buffer cylinder 5 from directly driving the vibration-damping top plate 2 to move.

[0026] In this embodiment, a vibration isolation block 12 and a damping shock absorber 13 are fixed to the inner cavity surface of the vibration-damping base 1 ; and the vibration isolation block 12 is fixed at the interval between two adjacent groups of damping shock absorbers 13 .

[0027] As a preferred embodiment, the vibration-damping base 1, the vibration-damping top plate 2, the limit plate 21, the buffer cylinder 5, the damping shock absorber 13 and the buffer chamber 54 constitute the vibration-damping mechanism of the polyurethane floor body 3. While the vibration-damping mechanism of the polyurethane floor body 3 plays a role in vibration reduction, it prevents the deformation force generated by the vibration reduction of the damping shock absorber 13 from driving the polyurethane floor to move, facilitates the isolation of the vibration reduction amplitude of the bottom surface of the polyurethane floor, and ensures that the polyurethane floor at the upper end of the shock absorber is installed more firmly.

[0028] The polyurethane floor vibration damper of the utility model can effectively solve the problem in the prior art that the polyurethane floor vibration damper is not durable due to the short long-term compression life of the double-layer vibration damping pad. It is convenient to isolate the vibration damping amplitude of the bottom surface of the polyurethane floor, facilitate the installation of the polyurethane floor at the upper end of the vibration damper to be more stable, and improve the durability of the polyurethane floor vibration damper. It is suitable for polyurethane floor vibration dampers.
