Description

Technical Field

[0001] The invention relates to the technical field of slide rail bolts, and in particular to an adjustable ship slide rail bolt and a locking method thereof. Background Art

[0002] A rail bolt is a mechanical structure that combines a slide rail and a locking device, usually used to fix or move objects. It contains a sliding rail part and a locking bolt structure, which is mainly used to move on the track and lock in a specific position. The main function of the rail bolt is to provide smooth sliding on the track and be able to fix the sliding part in the desired position through the locking device when needed. The design of the rail bolt can be applied to various scenarios, such as ship mooring systems, fixing of industrial equipment, positioning of mechanical components, etc. Through this combined sliding and locking design, the rail bolt can provide flexibility during sliding while ensuring sufficient stability when locked to prevent unnecessary movement or displacement.

[0003] Existing cable bolt products, whether made of stainless steel or die-cast aluminum, have the same limitations, namely, these cable bolts are usually fixedly installed at a certain position on the hull and cannot be flexibly adjusted, resulting in inconvenience in use. Since these cable bolts cannot change their positions according to actual needs, the ship must predict the mooring position and direction in advance when docking, especially in complex seaport or dock environments, where operation is more difficult. The ship may need to be repeatedly adjusted according to the conditions of a specific docking point, which increases the workload of the crew and reduces the efficiency and safety of mooring. The fixed-position cable bolt cannot adapt to changes in different mooring conditions, limiting the flexibility of the ship, especially in the case of strong winds and waves, the hull position cannot be flexibly adjusted, which can easily lead to danger. In addition, the fixed nature of the cable bolt also limits the ship's ability to respond quickly in various environments, and cannot meet the increasingly complex navigation needs, making mooring operations more cumbersome and time-consuming.

Each group of oil outlets is designed in an "eight" shape. As the bolt body slides quickly on the slide rail, inertia causes the first movable baffle and the second movable baffle to gradually open the oil outlet, thereby ensuring that the grease is effectively discharged during the operation of the equipment. When the sliding stops, the reset spring closes the oil outlet in time to prevent excessive grease from being discharged, thereby ensuring the stability and efficiency of the lubrication effect. At the same time, the setting of the rubber sealing gasket ensures good sealing at the oil outlet in the non-working state, thereby preventing grease leakage and ensuring the long-term reliability of the lubrication device. In addition, the hollow structure of the fixed column and the oil filling hole design facilitate the replenishment of the lubricating oil, thereby ensuring that the system always has sufficient grease reserves during long-term use, thereby greatly reducing the maintenance frequency and extending the service life of the equipment.

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0021] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components.

When the bolt body 1 moves to the appropriate position, the operator uses the locking component again to fix the sliding positioning pin 5 to the slide rail to ensure that the bolt is stably locked in the specified position. During this process, the lubrication component continuously self-lubricates the connection between the fixed slide rail 2 on the ship's side and the external slide rail to ensure a smooth sliding process and reduce wear. The bolt body 1 is made of 316L stainless steel and has high strength and corrosion resistance. It is very suitable for use in ship environments, especially in seawater environments. Its rust resistance is significant, ensuring the long service life of the bolt. The manual mirror treatment on the surface not only improves the corrosion resistance, but also enhances the aesthetics, reduces friction and dirt adhesion, and the sliding positioning pin 5 is controlled by the locking component to achieve a stable connection between the bolt body 1 and the external slide rail, thereby ensuring the stability of the bolt in use.

[0024] like Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, the lubrication assembly includes a slide rail lubricating grease bin 11 fixedly installed inside the other side of the cable bolt body 1, a positioning cylinder 12 is fixedly installed inside the slide rail lubricating grease bin 11, an oil outlet cavity 21 is arranged between the slide rail lubricating grease bin 11 and the positioning cylinder 12, a plurality of lubrication ports 22 are provided above the oil outlet cavity 21, and the lubrication ports 22 are used to discharge lubricating liquid or lubricating grease, a fixed column 14 is axially installed in the middle of the inner side of the positioning cylinder 12, an oil storage cavity 13 is arranged between the outer wall of the fixed column 14 and the inner wall of the positioning cylinder 12, the fixed column 14 is hollow, an oil filling hole 15 is provided on one side of the inner wall of the fixed column 14, and the oil filling hole 15 is used to replenish and inject lubricating grease, and a plurality of groups of oil outlets 16 are provided on the side wall of the positioning cylinder 12, and the plurality of groups of oil outlets 16 are used to discharge the lubricating grease inside the oil storage cavity 13 into the inside of the oil outlet cavity 21; When the equipment needs lubrication, the lubricating grease in the oil storage chamber 13 automatically flows into the oil outlet chamber 21 through the plurality of oil outlets 16 on the side wall of the fixing column 14, and the lubricating grease in the oil outlet chamber 21 is evenly discharged through the lubrication port 22 to lubricate the connection portion between the cable bolt body 1 and the external slide rail. During use, the hollow structure of the fixing column 14 can be replenished with lubricating grease at any time through the oil filling hole 15 to ensure that the lubricating grease bin always has sufficient reserves. The system automatically distributes grease while maintaining the continuity of the lubrication effect, thereby avoiding equipment wear and ensuring smooth operation.

[0025] like Figures 6 to 9 As shown, each group of oil outlets 16 is provided with three, and the three oil outlets 16 are arranged in a circumferential manner on the inner side of the outer wall of the oil storage chamber 13, the angle between the three oil outlets 16 is 120 degrees, the oil outlet 16 is arranged in an "eight" shape, narrow inside and wide outside, and a first movable baffle 18 and a second movable baffle 19 are movably installed inside the oil outlet 16, the first movable baffle 18 and the second movable baffle 19 are arranged opposite to each other, and the first movable baffle 18 and the second movable baffle 19 are meshed in an oblique toothed manner at the opposite positions, and the oil outlet 16 Two slide grooves are respectively provided on both sides of the first movable baffle 18 and the second movable baffle 19, and sliders adapted to the slide grooves are respectively provided on the side of the inner wall of the oil outlet 16, and two fixed blocks 17 are respectively fixedly installed on the side of the oil outlet 16 close to the oil storage chamber 13, and return springs 23 are respectively provided between the two fixed blocks 17 and the first movable baffle 18 and the second movable baffle 19, and a sealing gasket 20 is provided at the meshing position opposite to the first movable baffle 18 and the second movable baffle 19, and the sealing gasket 20 is made of rubber; During the lubrication process, it is necessary to release the fixing of the limit pin, and then quickly slide the bolt body 1 on the slide rail. When the bolt body 1 slides quickly on the slide rail, the inertia causes the first movable baffle 18 and the second movable baffle 19 of the oil outlet 16 to slide in the slide groove. The two baffles gradually open the "eight"-shaped oil outlet 16 during the sliding process, and the lubricating grease is discharged through the oil outlet 16 to provide lubrication between the bolt body 1 and the slide rail. When the sliding stops, the reset spring 23 pushes the two movable baffles to return to their original position, and the oil outlet 16 is closed to prevent the grease from continuing to be discharged. No additional operation is required during the whole process. The lubrication process is automatically completed according to the sliding of the bolt, and it automatically resets when it stops, ensuring the accuracy and efficiency of the lubrication. The rubber sealing gasket 20 arranged at the oil outlet 16 ensures that the oil outlet 16 is well sealed when not in use to prevent the leakage of lubricating grease, while ensuring the long-term performance of the lubrication device and extending the service life of the equipment.
