The marine chain is used for connecting two marine railings 4 arranged at intervals, so that the safety factor of the ship is improved, and the navigation safety is ensured.

The buckle 1 includes a fixed member 11 and a movable member 12, two ends of the fixed member 11 correspond to two ends of the movable member 12, and the fixed member 11 and the movable member 12 form a closed loop. The movable member 12 includes a connecting end 121 and a movable end 122, the connecting end 121 is movably connected to the fixed member 11, and the movable end 122 can form an opening 13 with the fixed member 11. In this embodiment, the connecting end 121 is connected to the fixed member 11 by the spring 14, and the opening 13 between the movable end 122 and the fixed member 11 can be formed by pressing the movable member 12.

In other alternative embodiments, the connecting end 121 and the fixing member 11 may be made of other elastic members, not limited to the spring 14, and the elastic members may be automatically restored after the movable end 122 and the fixing member 11 form the opening 13. The movable member 12 and the fixed member 11 may be connected by a non-elastic member.

Both ends of the fixing part 11 along the length direction of the marine chain are arc sections, wherein the arc section close to one end of the fixing ring 3 is a first arc section 111, the arc section close to one end of the chain body 2 is a second arc section 112, and the first arc section 111 and the second arc section 112 are connected through two straight line sections 113. Because the opening 13 of the buckle 1 is formed by moving the movable end 122 of the movable member 12, the width of the buckle 1 close to one side of the movable end 122 is preferably greater than the width of the buckle 1 close to one side of the connecting end 121, that is, the diameter of the first arc section 111 is greater than the diameter of the second arc section 112, so as to leave a sufficient moving space for the movable end 122, and facilitate the chain body 2 and the fixing ring 3 to be sleeved into the buckle 1 through the opening 13.

The movable end 122 of the movable member 12 is fastened to the fixed member 11, the fixed member 11 is provided with a first recess 114 and a first protrusion 115, the movable end 122 is provided with a second recess 123 and a second protrusion 124, the second protrusion 124 is matched with the first recess 114, the first protrusion 115 is matched with the second recess 123 to fasten the movable end 122 and the fixed member 11, and the fixed member 11 is used for limiting the movement of the movable end 122 along the length direction of the marine chain.

The second circular arc segment 112 of the fixing member 11 is provided with a groove 116, and the groove 116 is used for limiting the movement of the chain body 2 in the closed loop to prevent the chain body 2 from being disconnected from the buckle 1. Because the ship hull is always in a shaking state under the influence of water flow and wind power during offshore operation, the ship chain connected to the ship hull is also always in a shaking state, in order to prevent the chain ring 21 sleeved in the ring buckle 1 from wearing the ring buckle 1 and the ship hull due to continuous shaking and reduce the possibility of accidentally opening the opening 13 between the movable end 122 and the fixing piece 11 due to the above reasons, the position of the chain ring 21 sleeved in the ring buckle 1 needs to be further limited, and the chain ring 21 is clamped into the groove 116 of the fixing piece 11 to limit the movement of the chain body 2 in the closed ring.

The groove 116 of the fixing member 11 is a circular arc-shaped groove, the width direction of the opening 13 of the groove 116 is parallel to the width direction of the buckle 1, and the width of the opening 13 of the groove 116 is smaller than the diameter of the link 21, so as to prevent the link 21 clamped in the groove 116 from entering the annular space of the buckle 1 from the opening 13 of the groove 116. The diameter of the recess 116 is larger than the diameter of the link 21 to enable the link 21 to move within the recess 116 to enhance the flexibility of the marine chain.

In other alternative embodiments, the recess 116 may have other configurations, such as a C-shaped recess, but the width of the opening 13 of the recess 116 should be smaller than the diameter of the link 21, so as to prevent the link 21 snapped into the recess 116 from entering the annular space of the buckle 1 from the opening 13 of the recess 116. The maximum width of the recess 116 is preferably greater than the diameter of the chain ring 21 to facilitate movement of the chain ring 21 within the recess 116.

The embodiment also provides a ship chain locking method, as shown in fig. 5, the method adopts the ship chain as described above, and the ship chain locking method comprises the following steps:

s1, fixing two fixing rings 3 on two marine railings 4 arranged at intervals respectively;

s2, sequentially buckling a plurality of chain rings 21 to form a chain body 2;

s3, buckling one end of the chain body 2 with a fixing ring 3;

s4, controlling the movable end 122 to move to form an opening 13, and sleeving the chain body 2 into the buckle 1 from the opening 13;

s5, resetting the movable piece 12;

s6, clamping the chain body 2 into the groove 116;

s7, controlling the movable end 122 to move to form an opening 13, and sleeving the other fixing ring 3 into the buckle 1 from the opening 13;

and S8, resetting the movable piece 12.

Fix fixed ring 3 on marine railing 4 earlier, in order to guarantee the fastness of both connections, can weld fixed ring 3 on marine railing 4. Then, the plurality of chain rings 21 are sequentially buckled to form the chain body 2, the length of the chain body 2 is determined by the distance between two adjacent marine railings 4, and the larger the distance between two adjacent marine railings 4 is, the longer the chain body 2 is, and the more the number of the chain rings 21 for forming the chain body 2 is, because the sizes of the ring buckles 1 and the fixing rings 3 are basically fixed; conversely, the smaller the spacing between two adjacent balustrades 4, the shorter the chain body 2, and the smaller the number of links 21 forming the chain body 2.

After the chain body 2 is manufactured, the chain ring 21 at one end of the chain body 2 is buckled with one fixing ring 3, the chain ring 21 at the other end of the chain body 2 is buckled with the ring buckle 1, and then the ring buckle 1 is buckled with the other fixing ring 3 to realize that the two ends of the marine chain are fixed on the marine handrail 4.

Since the connection end 121 of the movable member 12 of the buckle 1 is connected to the fixed member 11 of the buckle 1 by the spring 14, in steps S4 and S7, the movable end 122 is moved toward the inside of the buckle 1 by pressing the movable member 12 to form the opening 13, and the spring 14 is compressed by the pressure, so that the opening 13 is formed between the movable end 122 and the fixed member 11. After the chain body 2 and the fixing ring 3 are sleeved into the buckle 1 from the opening 13, in step S5 and step S8, the movable member 12 can be reset by loosening the movable member 12, the pressure applied to the spring 14 disappears, and the spring 14 resets under the action of elastic force, so that the movable end 122 is driven to move to the outside of the buckle 1, and the movable member 12 resets.

The second arc section 112 of the movable member 12 is provided with an arc-shaped groove 116, the width of the opening 13 of the arc-shaped groove 116 is slightly smaller than the diameter of the chain ring 21, after the chain ring 21 of the chain body 2 is sleeved into the buckle 1, the chain ring 21 is aligned with the arc-shaped groove 116, and then the buckle 1 and the chain body 2 are pulled in opposite directions, so that the chain ring 21 can be completely clamped into the arc-shaped groove 116. In other alternative embodiments, after aligning the chain ring 21 sleeved in the buckle 1 in the chain body 2 with the circular arc-shaped groove 116, one of the buckle 1 and the chain body 2 can be fixed, and the other one is pulled in a direction away from the fixed buckle 1 or the chain body 2, and the chain ring 21 can be completely clamped in the circular arc-shaped groove 116

The marine chain in this embodiment can realize locking and opening for marine railing 4 through latch closure 1, even the boats and ships shake, violently or receive accidental collision, also be difficult to break off the connection of marine chain and marine railing 4, improve boats and ships factor of safety. When the marine handrail is required to be opened, the buckle 1 can be sleeved out from the fixing ring 3 fixed on the marine handrail 4 directly by pressing the movable piece 12, and the operation is convenient. Meanwhile, the buckle 1 is simple in structure, convenient to produce and manufacture and low in processing cost, and production cost is effectively reduced while safety of operators is guaranteed.
