[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1-6 A wire rope connection lock comprises a base 1, a support base 2 installed on the base 1 and a U-shaped pin 3 installed between the base 1 and the support base 2. A storage cavity 101 is opened inside the base 1, and threaded holes 102 communicating with the storage cavity 101 are opened at both ends of the base 1 close to the support base 2. The inner walls of the two threaded holes 102 are connected with anti-loosening components, and the interior of the storage cavity 101 is connected with a transmission component. The other two ends of the transmission component are connected with limiting components, and the two limiting components are respectively matched with the two anti-loosening components, and the two limiting components are respectively connected to the two ends of the U-shaped pin 3.

[0022] like Figures 1 to 6 As shown, when the wire rope connecting lock in the present invention is used, the wire rope is first passed through the space between the U-shaped pin 3 and the support seat 2, and then the two ends of the U-shaped pin 3 are aligned with the two jacks of the support seat 2 and the base 1 and inserted. When the two ends of the U-shaped pin 3 are inserted into the storage cavity 101, they will be blocked by the two limit assemblies. At this time, you only need to rotate the transmission assembly, and the transmission assembly will drive the two limit assemblies to rotate at the same time. After the two limit assemblies are rotated, the two ends of the U-shaped pin 3 will be screwed into the interior of the limit assembly by means of threads, and then continue to screw in, and the two wire ropes can be gradually squeezed tight by the U-shaped pin 3 and the support seat 2, which is convenient and quick.

[0023] After the U-shaped pin 3 and the support seat 2 have limited and tightened the wire rope, in order to prevent the lock from loosening during use, the two anti-loosening components are manually rotated at this time. The two anti-loosening components will respectively rest against the surfaces of the two limiting components, thereby increasing the limiting tightness of the limiting component on the U-shaped pin 3 and reducing the probability of loosening.

[0024] It should be noted here that: because the two anti-loosening components limit the two limit components respectively, there will be no uneven force even if they are operated separately.

[0025] like Figure 3-Figure 6As shown, the transmission assembly includes a chain 8, a rotating assembly and two sprockets 7. The lower end of the rotating assembly is located outside the base 1, and the upper end of the rotating assembly passes through the base 1 to the inside of the storage cavity 101 and is connected to the bottom surfaces of the two sprockets 7. The upper ends of the two sprockets 7 are respectively connected to the lower ends of the two limit assemblies. The chain 8 is sleeved on the outer walls of the two sprockets 7, and the chain 8 is engaged with both sprockets 7.

[0026] More specifically, when the U-shaped pin 3 needs to be limited, it is only necessary to rotate the rotating component. At this time, the rotating component can rotate with the two sprockets 7 at the same time through the chain 8. As the two sprockets 7 rotate, the two limiting components will also rotate at the same time. After the two limiting components rotate, the two ends of the U-shaped pin 3 can be gradually screwed into the inside, thereby achieving the limitation of the wire rope.

[0027] like Figure 5 and Figure 6 As shown, the rotating assembly includes a hollow knob 5 and an anti-slip ring 11, and a rotating opening 103 and an anti-slip opening 104 are provided on the bottom surface of the storage cavity 101. The upper end of the hollow knob 5 is fixedly connected to the bottom surface of one of the sprockets 7, and the lower end of the hollow knob 5 passes through the rotating opening 103 to the outside of the base 1. The outer wall of the hollow knob 5 is rotatably connected to the inner wall of the rotating opening 103, the upper end of the anti-slip ring 11 is fixedly connected to the bottom surface of the other sprocket 7, and the outer wall of the lower end of the anti-slip ring 11 is rotatably connected to the inner wall of the anti-slip opening 104. The hollow knob 5 and the anti-slip ring 11 are respectively located on the outer walls of the two ends of the U-shaped pin 3, and the inner wall of the hollow knob 5 is slidably connected to the outer wall of the U-shaped pin 3.

[0028] More specifically, when it is necessary to lock the wire rope, it is only necessary to rotate the hollow knob 5. After the hollow knob 5 is rotated, the sprocket 7 connected to it will rotate, thereby achieving the above-mentioned step of screwing the U-shaped pin 3 into the interior; and the other sprocket 7 will also rotate normally in the storage cavity 101 due to the anti-slip ring 11 and the anti-slip mouth 104, and will not fall off and separate from the storage cavity 101.

[0029] like Figure 3-Figure 6 As shown, the limiting assembly includes a connecting column 6, a connecting ring 9 and several No. 1 wedge blocks 10. The bottom surface of the connecting ring 9 is fixedly connected to the upper surface of the sprocket 7, the upper surface of the connecting ring 9 is fixedly connected to the bottom surface of the connecting column 6, the upper surface of the connecting column 6 is fixedly connected to the bottom surfaces of several No. 1 wedge blocks 10, the inner wall of the connecting column 6 is threadedly connected to the outer wall of the U-shaped pin 3, and the several No. 1 wedge blocks 10 are all matched with the anti-loosening assembly.

[0030] More specifically, when the sprocket 7 rotates, it will rotate with the connecting column 6 through the connecting ring 9. After the connecting column 6 rotates, the U-shaped pin 3 passing through the inside can be screwed into the inside and gradually tightened.

[0031] like Figure 4 and Figure 5 As shown, the anti-loosening assembly includes an extrusion ring 4 and several No. 2 wedge blocks 12. The outer wall of the extrusion ring 4 is threadedly connected to the inner wall of the threaded hole 102. The bottom surface of the extrusion ring 4 is fixedly connected to the upper surfaces of the several No. 2 wedge blocks 12. The several No. 2 wedge blocks 12 are respectively matched and aligned with the several No. 1 wedge blocks 10.

[0032] More specifically, after the U-shaped pin 3 and the support seat 2 lock the wire rope, it is only necessary to rotate the extrusion ring 4, and the extrusion ring 4 can rotate with the No. 2 wedge block 12. Because the No. 2 wedge block 12 is in the opposite direction to the No. 1 wedge block 10, it will gradually lock after contact. After locking, because the No. 2 wedge block 12 is in the opposite direction to the No. 1 wedge block 10, it will not easily loosen, thereby increasing the limit stability.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
