Corresponding place is provided with b half groove, and a half groove combines the straight hole being formed for mounting hook portion with b half groove.
Further, described a half cavity and b half cavity be shaped as hemispherical, being shaped as of rotatable parts is spherical.
Further, the diameter with diameter greater than described straight hole of described cavity.
Further, it is provided with a through hole above described a half cavity, above b half cavity, place corresponding with a through hole is provided with b and leads to
Hole, a through hole combines the through hole being formed for through hoist cable with b through hole.
Further, described hook portion is formed in one the hook of structure.
Further, described hook portion is made up of case hardening steel.
This utility model compared with prior art, has advantages below and a beneficial effect:
(1), in this utility model, one end of hook portion is provided with hook, the other end is provided with rotatable parts, and load portion is provided with
Spherical hollow space and straight hole, rotatable parts are rotatably installed in cavity, the diameter with diameter greater than described straight hole of described cavity, adopt
Install after rotatable parts with said structure, hook portion can not come off from load portion because rotatable parts are blocked by cavity wall,
Thus ensure that safety of the present utility model；
(2) load portion of the present utility model is combined by positive stop and backstop, by screw and nut cooperation fastening,
So that removing and installing conveniently；
(3) this utility model offers through hole in load portion, and hoist cable passes through through hole, and load portion is suspended on hoist cable, adopts
With said structure, hoist cable can be made to be applied to the counteracting force in the load portion active area in load portion bigger, and then make
Load portion will not be pulled off because of the counteracting force that hoist cable applies, thus strengthening safety of the present utility model；
(4) this utility model adopts case hardening steel integrated formed structure, and case hardening steel is due to case-carbonizing so that table
Face has very high hardness it is ensured that the deformation of this utility model portion, and in addition case hardening steel internal toughness is strong, can absorb this practicality
The part that Novel connecting is subject to is impacted, and then ensures that this utility model is pulled off, thus strengthening this utility model in the middle part of practical process
Safety.
(5) rotating part in this utility model, cavity be set to spherical so that this utility model rubbing in rotation process
Wiping power reduces, thus strengthening motility of the present utility model.
