The embodiments described below by referring to the drawings are exemplary only, and are for the purpose of explanation of the present application, and cannot be understood as a limitation of the present application.

[0045] The following refers to Figures 1-5 A hook according to an embodiment of the present application is described. The hook is used to connect between a first end and a second end of a steel wire rope of a studded chain, so that the steel wire rope forms a loop of steel wire rope end to end on the inner side of a wheel. As Figure 1 shown, the hook comprises a first hook 100 and a second hook 200 connected detachably, the first hook 100 is connected to the first end of the steel wire rope, the second hook 200 is connected to the second end of the steel wire rope, and the first hook 100 is connected to the second hook 200, so that the steel wire rope can be connected into a loop.

[0046] As Figure 2 shown, the first hook 100 comprises a first cover plate 410, a first connecting piece 430 and a second cover plate 420 stacked; the first cover plate 410, the first connecting piece 430 and the second cover plate 420 are each provided with a plurality of through holes 510 near the edge area, and a connecting nail 520 is correspondingly mounted on each through hole 510, which is inserted into the through hole 510 to fix the first cover plate 410, the first connecting piece 430 and the second cover plate 420.

[0047] The first connecting piece 430 can be provided separately or integrally formed, specifically, as Figure 4As shown, the first connecting piece 430 comprises a first connecting plate 431 and a second connecting plate 432 which are stacked.

[0048] The second connecting plate is provided with the positioning part 110 which is located on one side of the first cover plate 410, the first connecting plate 431 and the second cover plate 420.

[0049] Further, the position of the second connecting plate 432 opposite to the positioning part 110 can be provided with a punching hole, and the positioning part 110 is a hook formed outside the punching hole after the material in the punching hole is formed by punching and stamping, and the positioning part 110 and the second connecting plate 432 of the first hook 100 form a buckle groove 111. Figure 2 As shown, the second hook 200 comprises a first cover plate 410, a second connecting piece 440 and a second cover plate 420 which are stacked; the edge-adjacent area of the first cover plate 410, the second connecting piece 440 and the second cover plate 420 is provided with a plurality of through holes 510, and a connecting nail 520 is installed on each through hole 510, and the connecting nail 520 is inserted into the through hole 510 to fix the first cover plate 410, the first connecting piece 430 and the second cover plate 420.

[0050] The second connecting piece 440 can be separately provided or integrally formed, and specifically, Figure 3 As shown, the second connecting piece 440 comprises a third connecting plate 441 and a fourth connecting plate 442 which are stacked; one end of the fourth connecting plate 442 is provided with the positioning hole 210 which is located on one side of the first cover plate 410, the third connecting plate 441 and the second cover plate 420.

[0051] As shown, Figure 4 and Figure 5 As shown, the positioning hole 210 of the fourth connecting plate 442 of the second hook 200 is sleeved on the positioning part 110 of the second connecting plate 432 of the first hook 100, and cooperates with the buckle groove 111 of the positioning part 110.

[0052] The first hook 100 is used for connecting the first end of the steel wire rope, and the second hook 200 is used for connecting the second end of the steel wire rope, so that the first end and the second end of the steel wire rope are detachably connected through the first hook 100 and the second hook 200.

[0053] It should be noted that the first hook 100 is connected to the first end of the steel wire rope, the second hook 200 is connected to the second end of the steel wire rope, the first hook 100 is connected with the second hook 200 to connect the steel wire rope into a loop and be arranged inside the wheel; the chain is connected with the steel wire rope and is sleeved on the wheel; the outer side of the wheel can be provided with a tensioning mechanism. The tensioning mechanism exerts a pre-tightening force on the chain on the outer side of the wheel, and then the force exerted by the chain on the second end of the steel wire rope is opposite to the force exerted by the chain on the first end of the steel wire rope; so that the second hook 200 and the first hook 100 stably realize buckling. When the pre-tightening force exerted by the tensioning mechanism on the chain on the outer side of the wheel is cancelled, and the positioning hole 210 of the second hook 200 is removed from the positioning portion 110 of the first hook 100, the second hook 200, the first hook 100, the steel wire rope and the chain can be removed from the wheel.

The above operation process is convenient and the operation difficulty is reduced.

[0055] As shown in Figure 4 In some embodiments, two sides of the first hook 100 are provided with limiting portions 130, and a limiting groove 131 is formed between the two limiting portions 130 and the first hook 100; when the positioning hole 210 is sleeved on the positioning portion 110, the second hook 200 cooperates with the limiting groove 131.

[0056] It should be noted that in the case where there is no limiting portion 130, and when the wheel rotates, the first hook 100 and the second hook 200 will relatively rotate due to the action of external force, which may cause the positioning portion 110 of the first hook 100 to fall off from the positioning hole 210 of the second hook 200, and then the steel wire rope and the chain fall off from the wheel.

[0057] In the present embodiment, the second hook 200 is limited in the limiting groove 131, which can avoid the relative rotation of the second hook 200 and the first hook 100, thereby improving the stability of the connection between the second hook 200 and the first hook 100.
