[0037] The wire rope guard sleeve 4 and the connecting member 5 are both installed inside the wire rope ball 3; the spherical joint 2 passes through the wire rope guard sleeve 4 and then into the interior of the connecting member 5; the locking assembly passes through the wire rope ball 3 and the connecting member 5 in turn, and is used to limit the spherical joint 2 located inside the connecting member 5.

[0038] In a preferred embodiment, the wire rope ball 3 includes a hemispherical body 31 with a hollow interior, and a conical mounting sleeve 32 is fixedly provided on the circular end surface of the hemispherical body 31, and the mounting sleeve 32 is caliber-contracted in the direction away from the hemispherical body 31;

[0039] An annular clamping platform 33 is fixedly provided inside the hemisphere 31, and a through hole 34 is provided on the side of the hemisphere 31 away from the mounting sleeve 32 corresponding to the inner ring diameter of the annular clamping platform 33; two first U-shaped notches 35 are symmetrically provided on the circumferential wall surface of the end of the mounting sleeve 32 away from the hemisphere 31.

[0040] In a preferred embodiment, the wire rope guard 4 includes a guard sleeve 41, the outer diameter of which is smaller than the diameter of the through hole 34, so that the guard sleeve 41 can pass through the through hole 34; the wire rope 1 passes through the inside of the guard sleeve 41, and the guard sleeve 41 is used to protect the wire rope 1.

[0041] An annular limiting platform 42 is fixedly provided on the circumferential outer side of one end of the wire protection sleeve 41. The outer diameter of the annular limiting platform 42 is larger than the inner diameter of the annular clamping platform 33 and smaller than the inner diameter of the hemispherical body 31. The annular limiting platform 42 cooperates with the annular clamping platform 33 to realize the clamping of one end of the wire rope protection sleeve 4 to the internal setting of the wire rope ball 3.

The flat end of the connecting member 5 extends into the interior of the wire rope ball 3 and abuts against the bottom surface of the annular limiting platform 42, thereby limiting the position of the wire rope sheath 4.

[0044] The connecting member 5 is provided with penetrating waist-shaped through holes 51 corresponding to the two first U-shaped notches 35 . The two first U-shaped notches 35 and the waist-shaped through holes 51 are arranged correspondingly to avoid interference with equipment that needs to pass through the waist-shaped through holes 51 .

[0045] An L-shaped channel 52 is provided between the planar end and the circumferential wall of the connecting member 5. A circular channel 53 is provided at one end of the L-shaped channel 52 located on the circumferential wall of the connecting member 5. The circular channel 53 is connected to the L-shaped channel 52. Both the L-shaped channel 52 and the circular channel 53 are connected to the interior of the waist-shaped through hole 51.

[0047] Among them, the length of the L-shaped channel 52 located on the planar end of the connecting member 5 is greater than the end face radius of the connecting member 5, that is, after installation, it is necessary to meet the purpose of allowing the wire rope 1 to pass through its planar end without interfering with the wire rope sheath 4; and the L-shaped channel 52 is located on a section of the diameter of the planar end of the connecting member 5 located on the planar end of the connecting member 5.

[0049] In a preferred embodiment, the annular limit platform 42 is provided with a second U-shaped notch 43 corresponding to the L-shaped channel 52; wherein, a positioning strip 36 is fixedly provided inside the mounting sleeve 32 corresponding to the L-shaped channel 52 and the second U-shaped notch 43, and the positioning strip 36 is provided inside the second U-shaped notch 43 and the L-shaped channel 52, and is used to position the direction in which the connecting component 5 is installed inside the wire rope ball 3.

[0050] In a preferred embodiment, the diameter of the spherical joint 2 is smaller than the diameter of the circular channel 53, that is, the spherical joint 2 can enter the interior of the connecting member 5 through the circular channel 53; the diameter of the spherical joint 2 is larger than the width of the L-shaped channel 52, and after the spherical joint 2 enters the interior of the connecting member 5, it is stuck in a section of the L-shaped channel 52 below the plane end.

[0051] In a preferred embodiment, the diameter of the ball joint 2 is smaller than the inner diameter of the grommet 41 .

[0052] The working principle of this utility model:

[0053] The ball joint 2 is fixedly mounted on one end of the wire rope 1. The ball joint 2 passes through the through hole 34 and out from the other end of the mounting sleeve 32. The ball joint 2 then passes through the wire protection sleeve 41. The ball joint 2 then passes through the circular passage 53 and enters the waist-shaped through hole 51. The ball joint 2 is then clamped in the L-shaped passage 52 below the flat end.

[0054] After the above steps are completed, the wire rope sheath 4 and the connecting member 5 are placed together into the interior of the wire rope ball 3. At the same time, the positioning strip 36 is aligned with the second U-shaped notch 43 and the L-shaped channel 52, that is, the countersunk threaded hole 8, the threaded through hole 7 and the circular channel 53 are coaxially aligned, and then the countersunk locking bolt 6 is screwed into the countersunk threaded hole 8 and the threaded through hole 7 in sequence and penetrated into the interior of the circular channel 53 to complete the locking work, and at the same time, the spherical joint 2 inside the connecting member 5 is limited;

[0055] The overall structure is a split design, which makes installation and disassembly quick and efficient. The wire rope ball is not easy to loosen and has high safety performance.
