[0027] The following is combined with Figure 1-4 The utility model is described in further detail.
[0028] Please refer to the attached figure in the instruction manual Figure 1-4The utility model provides an embodiment of a marine engineering water-proof conduit with a buffer structure, comprising a protective conduit 1, one side of the protective conduit 1 is connected to a connecting rod 3, the connecting rod 3 is located around a gasket 4, and the connecting rod 3 is limited by the gasket 4 to ensure the stability of the protective conduit 1, the outer side of the gasket 4 is connected to a sealing block 2, and the outer side of the sealing block 2 is also connected to an undercut block 9, which makes the connection between the sealing block 2 and the sealing block 2 firmly sealed by the undercut block 9 to prevent water leakage;
[0029] A first shock-absorbing damper 6 is also provided at the center of the connecting rod 3, and a central block 5 is connected to the other side of the first shock-absorbing damper 6. The central block 5 cooperates with the first shock-absorbing damper 6 to perform shock-absorbing and buffering work on the connecting rod 3. Auxiliary blocks 7 are connected around the central block 5, and a protective block 8 is connected to the outside of the auxiliary block 7. The protective block 8 protects the outside of the sealing block 2 to prevent the waves from directly impacting the sealing block 2. The protective block 8 is connected around the bottom plate 13, and the outside of the bottom plate 13 is connected to the second shock-absorbing damper 12. The sliding block 10 is limited by the second shock-absorbing damper 12 to prevent it from hitting the top of the threaded nail 11. The other side of the second shock-absorbing damper 12 is connected to the sliding block 10, and the inner side of the sliding block 10 is provided with a threaded nail 11.
[0030] Working principle: When in use, first, place the sealing block 2 on both sides of the protective conduit 1, so that the grooves around the center of the gasket 4 pass through the connecting rod 3, until the sealing block 2 fits on the outside of the undercut block 9, completing the fixed installation of the sealing block 2, and then place the protective block 8 on the other side of the sealing block 2. At this time, the center block 5 fits on the connecting rod 3, so that the first shock absorber 6 starts to absorb the shock of the connecting rod 3, preventing the vibration of the connecting rod 3 from causing the vibration of the protective conduit 1. After that, fix the sealing block 2 on the other side to the protective conduit 1 in the same way;
[0031] As mentioned above, after the sealing blocks 2 on both sides are aligned, grab and lift the sliding block 10 so that it slides out of the protective block 8, and then pass the threaded nail 11 through the protective block 8 and the sealing block 2 in turn to complete the fixation with the protective conduit 1, and then release the sliding block 10. During use, the water pressure drives the sliding block 10 to fit against the surface of the threaded nail 11 to prevent the threaded nail 11 from falling loose.
[0032] It should be noted that connecting rods 3 are evenly and equidistantly distributed on both sides of the protective conduit 1. The connection between the connecting rods 3 and the gasket 4 is a sliding connection. The gasket 4 and the sealing block 2 are installed as an integral whole. The gasket 4 and the protective conduit 1 are connected by the connecting rods 3 to ensure subsequent use.
[0033] It should be noted that the cross-section of the sealing block 2 is a "U"-shaped structure. The sealing block 2 fits tightly around the center of the protective conduit 1. The connection between the sealing block 2 and the inverted block 9 is a sliding connection. Through the cooperation between the sealing block 2 and the inverted block 9, the outer side of the protective conduit 1 is initially limited, which facilitates the connection of the protective conduit 1.
[0034] It should be noted that the central block 5 is evenly and equidistantly distributed around the center of the auxiliary block 7, and the first shock-absorbing damper 6 is symmetrically distributed on both sides of the central block 5. The center of the central block 5 coincides with the center of the connecting rod 3. The central block 5 cooperates with the first shock-absorbing damper 6 to limit the connecting rod 3 to prevent the connecting rod 3 from being affected by vibration.
[0035] It should be noted that the auxiliary block 7 and the protective block 8 are installed in an integrated manner, and the sealing blocks 2 are symmetrically distributed on both sides of the protective block 8. The auxiliary block 7 is made of elastic rubber material, and the connection between the protective block 8 and the sealing block 2 is a sliding connection. The auxiliary block 7 prevents the sealing blocks 2 on both sides from colliding with each other, thereby playing a secondary buffering role.
[0036] It should be noted that the sliding block 10 and the protective block 8 are connected in a sliding manner. The sliding block 10 forms a shock-absorbing structure with the base plate 13 through the second shock-absorbing damper 12. There are threaded nails 11 evenly and equidistantly in the center of the protective block 8. The threaded nails 11 pass through the sealing block 2 and are attached to the surface of the threaded nail 11 through the sliding block 10 to prevent the threaded nail 11 from falling off due to vibration, thereby ensuring the stable connection of the threaded nail 11.
[0037] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
