[0027] Example 1
[0028] like Figure 1 - Figure 5 The illustrated lifebuoy fixing device for ships includes a base 1. A sliding groove 11 is provided inside the base 1. A sliding block 12 is slidably connected inside the sliding groove 11. The width of the sliding block 12 is equal to the width of the sliding groove 11. An adjustment mechanism 2 is provided inside the base 1. The adjustment mechanism 2 is used to fix lifebuoys of different diameters. A connecting block 15 is fixedly connected to one side of the sliding block 12 and slidably connected inside the base 1. A fixing block 13 is rotatably connected to one side of the sliding block 12. The fixing block 13 is arc-shaped. A spring 14 is rotatably connected to one side of the sliding block 12, with the end of the spring 14 away from the sliding block 12 rotatably connected to one side of the fixing block 13.
[0029] In this embodiment, the base 1 is made of high-strength, corrosion-resistant metal material to ensure long-term stable use in the complex marine environment of a ship and to resist seawater erosion and the effects of severe weather. The precisely opened sliding groove 11 inside forms a precise sliding fit with the sliding block 12. The two are of equal width, which not only ensures that the sliding block 12 slides smoothly in the sliding groove 11, but also enhances the stability of the entire structure and prevents shaking or displacement when the lifebuoy is fixed.
[0030] The adjustment mechanism 2 is ingeniously designed. Through the precise threaded connection between the threaded rod 21 and the connecting block 15, it achieves accurate fixation of lifebuoys of different diameters. This linear adjustment method is simple to operate and highly accurate. Crew members only need to rotate the turntable 24 to easily change the spacing of the fixing device to adapt to various lifebuoys, greatly improving the versatility and practicality of the device. The fixing block 13, which is rotatably connected to one side of the sliding block 12, is arc-shaped. Its curvature is precisely designed to closely fit the outer surface contour of common lifebuoys, providing uniform and stable support and preventing damage to the lifebuoys due to uneven local force during the fixing process.
[0031] Meanwhile, the spring 14 is made of high-elasticity, fatigue-resistant alloy steel. It plays a buffering role between the fixed block 13 and the sliding block 12. It can adapt to the slight size difference of the lifebuoy and effectively reduce the impact force between the lifebuoy and the fixing device when the ship is rocking, thus extending the service life of the lifebuoy.
[0032] Example 2
[0033] like Figure 1 - Figure 5 The life ring fixing device for ships shown includes an adjusting mechanism 2 comprising a threaded rod 21 rotatably connected to the inside of a base 1. The threaded portion of the outer wall of the threaded rod 21 is threadedly connected to a connecting block 15. A gear 22 is fixedly connected to one end of the threaded rod 21. The gear 22 is located inside the base 1. A gear disk 23 is rotatably connected inside the base 1. The gear disk 23 and the gear 22 mesh. A turntable 24 is fixedly connected to the center of the gear disk 23. The turntable 24 is located outside the base 1. A handle 25 is rotatably connected to one side of the turntable 24.
[0034] In this embodiment, the core component of the adjustment mechanism 2, the threaded rod 21, is rotatably connected to the inside of the base 1 via a high-precision bearing. This design greatly reduces the friction during the rotation of the threaded rod 21, making the adjustment process smoother and more stable, and ensuring the flexibility and stability of rotation during long-term use. The threaded portion on the outer wall of the threaded rod 21 adopts a standard and precise thread specification, achieving a precise threaded connection with the corresponding threaded hole on the connecting block 15, enabling extremely precise linear displacement adjustment. This precise adjustment mechanism allows the crew to accurately adjust the spacing of the fixing device to the appropriate position according to lifebuoys of different diameters, with minimal error, ensuring the stability of the lifebuoy fixation. One end of the threaded rod 21 is firmly fixed to the gear 22 using a key connection. The key connection ensures that the gear 22 and the threaded rod 21 can rotate synchronously, ensuring stable and reliable power transmission.
[0035] Inside the base 1, the gear disc 23 and gear 22 mesh with each other. Their tooth profile parameters are carefully designed to ensure both transmission efficiency and smooth power transmission. A turntable 24 is securely connected to the center of the gear disc 23 via fastening bolts. The turntable 24 is located outside the base 1 for easy operation by the crew. A handle 25 is rotatably connected to one side of the turntable 24 via a rotating connector. This design allows the operator to easily rotate the handle 25, which, through the meshing transmission of the gear disc 23 and gear 22, drives the threaded rod 21 to rotate, thereby adjusting the position of the lifebuoy. The entire operation is labor-saving and convenient. Even in complex environments such as ship rolling, the crew can easily complete the adjustment work, greatly improving operational efficiency and reducing manpower consumption.
[0036] Due to the precise meshing of the gear disc 23 and the gear 22, as well as the robust connection between the components, the entire adjustment mechanism 2 exhibits extremely high stability and reliability during operation. Fastening bolts tightly connect the turntable 24 to the gear disc 23, ensuring that the connection will not loosen under conditions of frequent operation and ship turbulence, thus guaranteeing the stability and accuracy of adjustment. This stable and reliable structural design not only extends the service life of the lifebuoy securing device but also provides strong support for the rapid retrieval of lifebuoys in emergency situations, effectively enhancing the ship's safety performance.
[0037] Working Principle: The base 1 is made of high-strength, corrosion-resistant metal, ensuring long-term stable use in the complex marine environment of a ship and resisting seawater erosion and the effects of severe weather. The precisely machined sliding groove 11 and sliding block 12 form a precise sliding fit, with equal widths. This not only ensures the smooth sliding of the sliding block 12 within the sliding groove 11 but also enhances the stability of the entire structure, preventing wobbling or displacement during lifebuoy fixing. The adjustment mechanism 2 is ingeniously designed, achieving precise fixing of lifebuoys of different diameters through a precise threaded connection between the threaded rod 21 and the connecting block 15. This linear adjustment method is simple to operate and highly accurate; crew members only need to rotate the turntable 24 to easily change the spacing of the fixing device, adapting to various lifebuoys and greatly improving the device's versatility and practicality.

Meanwhile, the spring 14, made of high-elasticity, fatigue-resistant alloy steel, acts as a buffer between the fixed block 13 and the sliding block 12. It can accommodate minor dimensional differences in the lifebuoys and effectively reduce the impact force between the lifebuoy and the fixing device during shipboard rocking, extending the lifebuoy's service life. The core component of the adjusting mechanism 2, the threaded rod 21, is rotatably connected to the base 1 via a high-precision bearing. This design greatly reduces the friction during the rotation of the threaded rod 21, making the adjustment process smoother and more stable, ensuring the flexibility and stability of rotation during long-term use. The threaded portion of the outer wall of the threaded rod 21 uses standard and precise thread specifications, achieving a precise threaded connection with the corresponding threaded hole on the connecting block 15, enabling extremely precise linear displacement adjustment. This precise adjustment mechanism allows crew members to accurately adjust the spacing of the fixing device to the appropriate position according to lifebuoys of different diameters, with minimal error, ensuring the stability of the lifebuoy fixation. One end of the threaded rod 21 is securely connected to the gear 22 via a key connection. The key connection ensures that the gear 22 and the threaded rod 21 can rotate synchronously, ensuring stable and reliable power transmission. Inside the base 1, the gear disc 23 and gear 22 mesh with each other. Their tooth profile parameters are carefully designed to ensure both transmission efficiency and smooth power transmission. A turntable 24 is securely connected to the center of the gear disc 23 via fastening bolts. The turntable 24 is located outside the base 1 for easy operation by the crew. A handle 25 is rotatably connected to one side of the turntable 24 via a rotating connector. This design allows the operator to easily rotate the handle 25, which, through the meshing transmission of the gear disc 23 and gear 22, drives the threaded rod 21 to rotate, thereby adjusting the fixed position of the lifebuoy.The entire operation is labor-saving and convenient. Even in complex environments such as ship rolling, crew members can easily complete the adjustment work, greatly improving operational efficiency and reducing manpower consumption. Due to the precise meshing of the gear 23 and gear 22, as well as the robust connection between various components, the entire adjustment mechanism 2 exhibits extremely high stability and reliability during operation. Fastening bolts tightly connect the turntable 24 and gear 23, ensuring that the connection will not loosen under frequent operation and ship rolling conditions, thus guaranteeing the stability and accuracy of the adjustment.
