[0012] Figure 1 It is a structural schematic diagram of the present invention.

[0013] Among them, 1. fishing head, 2. shell, 3. inlay, 4. main body pressure ring, 5. end cap, 6. main body, 7. pressure ring, 8. first vertebral body, 9. second vertebral body, 10. first fixing screw, 11. second fixing screw. DETAILED DESCRIPTION

[0014] The present patent application is further described below in conjunction with embodiments.

[0015] like Figure 1 As shown, a device suitable for connecting steel wire cables includes a body 6, a fishing head 1, a shell 2, and a primary locking structure and a secondary locking structure. The primary locking structure includes a body pressure ring 4, an end cap 5, a first vertebra 8, and a second vertebra 9; the secondary locking structure includes an inlay 3 and a pressure ring 7.

[0016] Specifically, one end of the housing 2 is embedded in the first vertebra 8 and the second vertebra 9, the second vertebra 9 is sleeved outside the first vertebra 8, the rear end of the first vertebra 8 is provided with an end cap 5, the end cap 5 is internally threadedly connected to the body 6, the outer wall of the body 6 close to the end cap 5 is sleeved with a body pressure ring 4, the body pressure ring 4 and the housing 2 are connected by threads and finally fixed by a second set screw 11. When connected, the outer armor wire of the steel cable is distributed between the first vertebra 8 and the second vertebra 9, the end cap 5 is axially pushed into the body pressure ring 4 by threading, and the vertebral body is squeezed to lock the outer armor wire of the steel cable to achieve primary locking.

[0017] The other end of the housing 2 is embedded with four inlays 3, and a pressure ring 7 is arranged outside the four inlays 3. Conical surfaces are formed at both ends of the inlay 3, and the conical surfaces are engaged with the pressure ring 7 and the conical surfaces of the inner wall of the housing 2. A fishing head 1 is arranged outside the pressure ring 7, and the fishing head 1 is connected to the housing 2 through threads and finally fixed by a first set screw 10. When connected, the steel wire cable passes through the fishing head 1, passes through the four inlays 3, and the pressure ring 7 is axially pushed by assembling the top fishing head 1. The pressure ring 7 and the conical surface inside the housing 2 are engaged with the four inlays 3, and the pressure ring 7 shrinks the four inlays 3, thereby shrinking and locking the steel wire cable to achieve secondary locking.

[0018] The two locking structures of the present invention lock the steel cable, and the bearing capacity after connection is greater than 19.5t, which can effectively lift the unit. In addition, the steel cable passes through the inner cavity of the device, and the device effectively protects the steel cable during operation; the two locking structures act on the outer armor steel wire of the cable, and will not cause damage to the cable.

[0019] The present invention is suitable for steel wire cables with a diameter of 29.85±1.5mm. The device has a length of 585mm and a diameter of 100mm, and can be used for narrow shaft operations. The tail end is provided with an M80x2-6g thread, which can be tightly connected to the unit.

[0020] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
