Chinese patent publication number: CN2771163 discloses a kind of quick-charge hoisting link, it comprises: C type ring body, and at the detachable connection of C type ring body indent assembling, the axle of in the middle of C type ring body, settling, at the spring and the nut of the upper end of axle installing, and locking swivel block and holding screw.Groove has been cancelled in described C type ring body inboard, and the nut on the described axle is a locknut, on the top of locknut the internal circlip of the effect of tightening up has been housed, and it is loosening to make nut be difficult for.But the volume of this quick-charge hoisting link product is done not quite, can not be used for large-scale hoisting sling rope sling.
Chinese patent publication number: CN201043116 discloses a kind of quick-release type C type hoisting link, and it comprises: C type ring body, detachable connection, fixed link and disassembly rotary block.The inside bottom surface of C type ring body and the bottom surface of detachable connection are respectively equipped with groove.Wave spring washer is equipped with on the top of fixed link, on the top of wave spring washer tight fixed bolt is housed.The top of disassembly rotary block is provided with the projection with the bottom recesses tabling of detachable connection, and the bottom surface of disassembly rotary block is provided with the projection that matches with the inside bottom surface groove of C type ring body.But this C type hoisting link needs to drill through the hole on ring body, has influenced the intensity of ring body.
In view of this, seek a kind of quick-charge hoisting link disassembly rotary block screw positioning and locking device, become pursuing one's goal of these those skilled in the art.
Summary of the invention
Task of the present invention provides a kind of quick-charge hoisting link disassembly rotary block screw positioning and locking device, it has overcome the shortcoming of above-mentioned prior art, the volume that has solved prior art products is done not quite, can not be used for large-scale hoisting sling rope sling and need on ring body, drilling through the hole, influence the problem of the intensity of ring body.
Technical solution of the present invention is as follows:
A kind of quick-charge hoisting link disassembly rotary block screw positioning and locking device, comprise C type ring body, indent assembling detachable connection at C type ring body, in the middle of C type ring body, settle disassembly rotary block, the inboard top and bottom of described C type ring body are equipped with groove, the upper and lower of described disassembly rotary block is respectively equipped with projection, and described groove and described projection are complementary;
The axle center of described disassembly rotary block is provided with through hole, and the inboard of described C type ring body is provided with the location blind hole, and described through hole is coaxial with described location blind hole;
Set gradually screw rod, lower compression spring and locknut in the described through hole;
Tight fixed bolt is set in the blind hole of described location and goes up compression spring;
