[0029] Figure 8 yes Figure 7 Cross-sectional view in CC direction; Figure 9 This is a schematic diagram of the assembly of the new shock absorbing device in this utility model. Figures 1 to 9 As shown, a preferred embodiment is shown, which shows a new type of shock absorbing device, including a shock absorbing pad 1, a spring 2, a skeleton layer 3, a protrusion 4, a connecting ring 5, a first connecting column 6 and a second connecting column 7. The skeleton layer 3 is provided inside the shock absorbing pad 1, and a plurality of protrusions 4 are evenly provided at the lower end of the shock absorbing pad 1. A mounting groove 8 is provided in the middle of the upper end of each protrusion 4, and a spring 2 is provided in the mounting groove 8. A plurality of first connecting columns 6 are provided at the lower end of the skeleton layer 3, a connecting ring 5 is provided at the outer edge of the upper end of the protrusion 4, and a plurality of second connecting columns 7 are provided on the connecting ring 5. The first connecting column 6 passes through the middle of the spring 2 and is detachably connected to the protrusion 4, and the second connecting column 7 is detachably connected to the skeleton layer 3. In this embodiment, see Figure 2 As shown, the bump 4 is detachably arranged at the lower end of the shock-absorbing pad 1 for supporting the shock-absorbing pad 1, and the skeleton layer 3 can be integrally formed and arranged inside the shock-absorbing pad 1, and the spring 2 is detachably arranged inside the bump 4. When the shock-absorbing pad 1 is squeezed, the shock-absorbing pad 1 can squeeze the bump 4 and the spring 2 to achieve a shock-absorbing effect.
[0030] The first connecting column 6 and the second connecting column 7 are used to connect the bump 4 to the skeleton layer 3 and the shock-absorbing pad 1, which facilitates the removal of the bump 4. The bump 4 is detachable. When a bump 4 is worn or damaged, the bump 4 can be removed separately for replacement without replacing the entire shock-absorbing pad 1, which can save costs.
[0031] The connecting ring 5 and the protrusion 4 are integrally formed. The connecting ring 5 can be made of rubber or metal and is used to mount the second connecting column 7 .
[0032] The bump 4 at the bottom of the shock-absorbing pad 1 in the prior art is an integrally formed setting. This setting method can easily affect the shock-absorbing effect when the bump 4 is worn, so the entire shock-absorbing pad 1 needs to be replaced, resulting in high maintenance costs. The bump 4 in the present application can be disassembled, which is convenient for individual replacement and has lower maintenance costs. Moreover, through the setting of the first connecting column 6 and the second connecting column 7, the bump 4 can be stably connected to the shock-absorbing pad 1 to avoid the bump 4 falling off when deformed.
[0033] Furthermore, as a preferred embodiment, the upper end of the first connecting column 6 is integrally connected to the lower end of the skeleton layer 3, the lower end of the first connecting column 6 is provided with a first limiting ring 9, the lower end of the second connecting column 7 is integrally connected to the connecting ring 5, and the upper end of the second connecting column 7 is provided with a second limiting ring 10. In this embodiment, the first limiting ring 9 is integrally formed with the first connecting column 6, and the second limiting ring 10 is integrally formed with the second connecting column 7. The outer diameter of the first limiting ring 9 is larger than the outer diameter of the first connecting column 6, and the outer diameter of the second limiting ring 10 is larger than the outer diameter of the second connecting column 7. A circular hole and a first limiting hole 11 are provided in the middle of the lower surface of the protrusion 4. The circular hole connects the first limiting hole 11 and the mounting groove 8. The circular hole, the mounting groove 8 and the first limiting hole 11 are coaxially arranged. The lower end of the first connecting column 6 passes through the circular hole, and the first limiting ring 9 is located in the first limiting hole 11. The first connecting post 6 is installed in the circular hole, and the first limiting ring 9 is installed in the first limiting hole 11, so that the first connecting post 6 can be connected to the protrusion 4. During the shock absorption process, the shock absorbing pad 1 squeezes the protrusion 4, causing the internal spring 2 to deform. At the same time, the first connecting post 6 will also deform. During this process, the protrusion 4 and spring 2 can be deformed. The elastic properties of the protrusion 4 and spring 2 can reduce the transmission of vibration and impact force, thereby achieving a shock absorption effect. When the spring 2 and protrusion 4 rebound, the tension of the first connecting post 6 and the second connecting post 7 can at least suppress some of the vibration and impact generated by the spring 2 and protrusion 4 rebounding after shock absorption, thereby achieving the purpose of energy consumption and facilitating the spring 2 and protrusion 4 to return to their original state.
[0034] Furthermore, as a preferred embodiment, a plurality of second limiting holes 12 are provided on the skeleton layer 3, the upper end of the second connecting column 7 passes through the second limiting hole 12, and the lower end of the second limiting ring 10 rests on the upper surface of the skeleton layer 3. When installing the first connecting column 6 and the second connecting column 7, a moving push can be applied to the first limiting ring 9 and the second limiting ring 10. At this time, the inner wall of the circular hole squeezes the first limiting ring 9, causing the first limiting ring 9 to deform, and then the thrust is continued to be applied to make the first limiting ring 9 enter the first limiting hole 11. Since the inner diameter of the first limiting hole 11 is larger than the outer diameter of the first limiting ring 9, the first limiting ring 9 at this time automatically returns to its original shape under the action of its own elastic properties, wherein the inner diameter of the circular hole is slightly smaller than the outer diameter of the first limiting ring 9.
[0035] When installing the second limiting column, push the second limiting ring 10. Since the inner diameter of the second limiting hole 12 is slightly smaller than the outer diameter of the second limiting ring 10, the second limiting ring 10 will be deformed until the second limiting ring 10 enters the upper surface of the skeleton layer 3. At this time, the second limiting ring 10 can automatically return to its original shape under the action of its own elasticity.
[0036] When the protrusion 4 needs to be removed, the protrusion 4 can be pulled hard, and the first limiting ring 9 and the second limiting ring 10 can automatically fall out after being deformed, thereby removing the protrusion 4, or the first limiting ring 9 and the second limiting ring 10 can be pushed with the help of external tools, so that the first limiting ring 9 falls out of the first limiting hole 11, and the second limiting ring 10 falls out of the second limiting hole 12.
[0037] Furthermore, as a preferred embodiment, a plurality of avoidance holes 13 are formed on the upper surface of the shock absorbing pad 1. The avoidance holes 13 are directly opposite to the second limiting holes 12, and the second limiting ring 10 is located in the avoidance holes 13. The inner diameter of the avoidance holes 13 is larger than the outer diameter of the second limiting ring 10 to facilitate accommodating the second limiting ring 10.
[0038] Furthermore, as a preferred embodiment, at least one exhaust hole is provided on the outer wall of the protrusion 4 , and the exhaust hole is connected to the mounting groove 8 , so that the air inside the protrusion 4 can be discharged when the protrusion 4 is squeezed.
[0039] Furthermore, as a preferred embodiment, the shock-absorbing pad 1, the first connecting column 6, the second connecting column 7, and the protrusion 4 are all made of rubber. The hardness of the rubber material of the first connecting column 6 and the second connecting column 7 can be greater than the hardness of the rubber material of the shock-absorbing pad 1 and the protrusion 4, so as to facilitate the installation of the first connecting column 6 and the second connecting column 7.
[0040] The longitudinal thickness of the protrusions 4 in this embodiment is smaller than the longitudinal thickness of the shock-absorbing pad 1 , and the number, length, and width of the protrusions 4 can be set as needed.
[0041] When used in conjunction with external equipment that requires shock absorption (such as an air handling unit or other device), a base 14, a top seat 15 and a damper 16 may be provided. Figure 9 As shown, the equipment requiring shock absorption is mounted on the top seat 15, the top seat 15 is mounted on the base 14, and the damper 16 and the new shock absorbing device in the utility model are mounted between the top seat 15 and the base 14, and the damper 16 is distributed on the periphery of the new shock absorbing device. The damper 16 is provided to provide resistance to movement. When the equipment vibrates, the top seat 15 is driven to move downward, thereby squeezing the shock absorbing pad 1, the bump 4 and the spring 2 to achieve a shock absorption effect.
[0042] In this embodiment, the shock-absorbing pad 1 can be connected to the lower end of the top seat 15 by screws, or the distance between the top seat 15 and the base 14 can be limited by the maximum stroke of the piston rod of the damper 16. This ensures that after the piston rod of the damper 16 has been extended to its maximum stroke, the shock-absorbing pad 1 can always contact the lower end of the top seat 15, and the bump 4 can always contact the upper end of the base 14. When the top seat 15 moves downward, the piston rod of the damper 16 contracts. Both the contraction and extension of the piston rod of the damper 16 can provide resistance to dissipate the energy generated by the vibration and the energy generated by the rebound of the spring 2 and the bump 4, allowing the top seat 15 to quickly return to its original position.
[0043] In this embodiment, the lower end of the damper 16 can be fixed to the base 14 by bolts, and the upper end of the damper 16 can be fixed to the top seat 15 by bolts. The provision of the damper 16 can provide a vertical support for the top seat 15. The novel shock absorbing device in this embodiment is mainly used for vertical vibration reduction of the equipment.
[0044] In this embodiment, the equipment requiring shock absorption can be fixed to the top seat 15 by bolt connection, and a plurality of bolt holes can be opened on the top seat 15 as needed.
[0045] In this embodiment, after the protrusion 4 is connected to the lower end of the shock-absorbing pad 1, the connecting ring 5 can be connected to the lower surface of the shock-absorbing pad 1 by dispensing glue, as long as it does not affect the normal removal of the protrusion 4. For example, applying glue to the four corners of the connecting ring 5 can achieve connection to the shock-absorbing pad 1 without affecting normal removal later. Alternatively, the four corners of the connecting ring 5 can be directly connected to the shock-absorbing pad 1 by screws. If screw connection is used, the connecting ring 5 and the shock-absorbing pad 1 at the locations where the screws connect need to be hardened to ensure strong hardness.
[0046] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
