[0002] The Kent connecting link, also known as the double-half connecting link, is mainly used to connect the front and rear sections of the anchor chain.

[0003] The existing double-half connecting link generally includes: a cross bar, a tapered pin and two half chain links. The two half chain links are butted to form a chain link. The cross bar is arranged between the two half chain links. The tapered pin is obliquely inserted through the two half chain links and the cross bar to fix the three, and a lead block is used to block and limit the tapered pin to prevent the tapered pin from loosening or disengaging. However, in actual use, the anchor chain is repeatedly jolted and vibrated, and the tapered pin is likely to come out, resulting in the disconnection of the two anchor chains. Moreover, the tapered pin is prone to breakage. When the tapered pin breaks, it can only be knocked out from the other end of the tapered pin, which is not convenient for replacement.

[0041] Embodiment 1:

[0042] As Figures 1-4 shown, a double-half connecting link mainly includes: a first half-link unit 1, a second half-link unit 2, a cross bar 3, a first fixing member 4, and a second fixing member 5.

[0043] The first half-link unit 1 is connected to the second half-link unit 2 to form a closed loop. Specifically, in this example, the structures of the first half-link unit 1 and the second half-link unit 2 are the same, which ensures simple manufacturing and improves interchangeability. Among them, the first half-link unit 1 and the second half-link unit 2 are arranged in central symmetry. At one end of the first half-link unit 1, there is a first clamping block 11, and on the second half-link unit 2, there is a first clamping groove 21. The first clamping block 11 is clamped in the first clamping groove 21. And, on the second half-link unit 2, there is a second clamping block 22, and on the first half-link unit 1, there is a second clamping groove 12. The second clamping block 22 is clamped in the second clamping groove 12. Through the clamping of the first clamping block 11 and the first clamping groove 21 and the clamping of the second clamping block 22 and the second clamping groove 12, the head and tail clamping of the first half-link unit 1 and the second half-link unit 2 is realized, forming a closed loop. It can be understood that after the first half-link unit 1 and the second half-link unit 2 are clamped, a structure similar to a complete chain link is formed. During the installation process, the first clamping block 11 can be horizontally inserted into the first clamping groove 21, and the second clamping block 22 can be horizontally inserted into the second clamping groove 12, ensuring the simple assembly between the first half-link unit 1 and the second half-link unit 2. Among them, the first clamping block 11 and the second clamping block 22 are preferably U-shaped clamping blocks, and the first clamping groove 21 and the second clamping groove 12 are preferably U-shaped clamping grooves. Through the one-to-one clamping adaptation of the two U-shaped clamping blocks and the two U-shaped clamping grooves, the clamping stability between the first half-link unit 1 and the second half-link unit 2 is good.

[0044] The cross bar 3 is arranged between the first half-link unit 1 and the second half-link unit 2, and separates the first connection hole 110 and the second connection hole 120 on the closed loop. The first connection hole 110 and the second connection hole 120 can be respectively used for connecting an anchor chain. The cross bar 3 separates two connection holes on the closed loop, which is convenient for connecting the anchor chain, and the anchor chain will not break away from the connection hole. Preferably, the cross bar 3 is fixed to both the first half-link unit 1 and the second half-link unit 2 in a clamping manner, ensuring that the cross bar 3 will not shift during use.

[0045] As Figures 4-6 shown, the first fixing member 4 connects the first half-link unit 1, the cross bar 3, and the second half-link unit 2 along the first direction; the second fixing member 5 connects the second half-link unit 2, the cross bar 3, and the first half-link unit 1 along the second direction; among them, the first direction and the second direction are arranged in the opposite direction. Specifically, the first direction and the second direction in this embodiment are the horizontal direction, ensuring convenient disassembly and assembly. It can be understood that the first fixing member 4 fixes the first half-link unit 1, the cross bar 3, and the second half-link unit 2 in the positive direction, and the second fixing member 5 fixes the first half-link unit 1, the cross bar 3, and the second half-link unit 2 in the reverse direction. No matter which direction the force acts on the double-half connecting link, it can ensure reliable fixation, that is, the structure of the double-half connecting link has good stability.

[0046] Specifically, the first fixing member 4 and the second fixing member 5 in this embodiment are both preferably bolts. Threaded holes are provided on both the first half-link unit 1 and the second half-link unit 2. The threaded hole on the first half-link unit 1 is the first threaded hole 10, and the threaded hole on the second half-link unit 2 is the second threaded hole 20. Moreover, bolt through-holes are provided on the first half-link unit 1, the second half-link unit 2, and the cross bar 3 to facilitate the bolts to pass through. Among them, the first fixing member 4 passes through the first half-link unit 1 and the cross bar 3 and is threadedly connected to the threaded hole (i.e., the second threaded hole 20) on the second half-link unit 2, detachably fixing and connecting the three. The second fixing member 5 passes through the second half-link unit 2 and the cross bar 3 and is threadedly connected to the threaded hole (i.e., the first threaded hole 10) on the first half-link unit 1, reversely detachably fixing and connecting the three. Further specifically, for the two bolts of the first fixing member 4 and the second fixing member 5, the rod segments without threads are conical surfaces. The conical surface on the first fixing member 4 fits with the cross bar 3 and the first half-link unit 1, and the conical surface on the second fixing member 5 fits with the cross bar 3 and the second half-link unit 2. After the first fixing member 4 and the second fixing member 5 are fixedly installed, lead blocks are encapsulated in the counterbores near their bolt heads.

[0047] Among them, one end of both the first fixing member 4 and the second fixing member 5 has a slotted crosshead or a Phillips head or an internal hexagonal socket, to facilitate a tool to penetrate into the end slot and turn the first fixing member 4 or the second fixing member 5.

[0048] During the actual use process, in this embodiment, the first fixing member 4 fixes the first half-link unit 1, the cross bar 3, and the second half-link unit 2 along the first direction, and the second fixing member 5 fixes the second half-link unit 2, the cross bar 3, and the first half-link unit 1 along the second direction, and the first direction and the second direction are opposite, ensuring the reliable fixed connection among the three, and further ensuring the structural stability of the double-half connecting link. When in use, the double-half connecting link is repeatedly jolted and vibrated, and the first fixing member 4 and the second fixing member 5 are not easily detached from among the first half-link unit 1, the cross bar 3, and the second half-link unit 2, ensuring that the structure will not fail. Further, both the first fixing member 4 and the second fixing member 5 adopt bolts, and the first half-link unit 1, the cross bar 3, and the second half-link unit 2 are detachably fixed by means of threaded connection, ensuring that the disassembly and assembly of the first fixing member 4 and the second fixing member 5 are simple and the replacement is convenient.

[0049] In this solution, the first half-link unit 1, the second half-link unit 2, and the cross bar 3 are fixed bidirectionally by the first fixing member 4 and the second fixing member 5, with good fixing effect and simple disassembly and assembly.

[0052] The double-half connecting link in the first embodiment;

[0053] It further includes a first anchor chain (not shown in the figure) and a second anchor chain (not shown in the figure). Among them, the first anchor chain is connected to the first connection hole 110, and the second anchor chain is connected to the second connection hole 120, so that the double-half connecting link connects the first anchor chain and the second anchor chain. By using the double-half connecting link to connect two anchor chains, when multiple anchor chains need to be connected, multiple double-half connecting links can be selected for docking.
