Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples. The specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

As shown in fig. 2-4, this embodiment provides a central apertured nipple hanger, which comprises a base 1 for supporting a central apertured nipple 8, a boom 5 connected to the base 1, and a hook 6 connected to the top end of the boom 5. As shown in fig. 1, a central apertured nipple 8 is shown, although the central apertured nipple 8 is not limited to this shape, and only the aperture of the central strap can pass through the cylindrical barrel 2 and the hanger of this embodiment can be hung; the welding of 1 up end center of collet has

cylindricality barrel

2, and 2 top internal fixations of cylindricality barrel have a shutoff piece, and the shutoff piece is the bearing capacity of integrated into one piece structure in order to guarantee the shutoff piece with cylindricality barrel 2, runs through the shutoff piece up end and has offered bar through-hole 3 down the terminal surface, the same bar counter bore 9 of size with bar through-hole 3 is seted up to the terminal surface under the shutoff piece, as shown in figure 4 an embodiment, bar through-hole 3 distributes with bar counter bore 9 mutually perpendicular, be equipped with cylindricality compression spring 7 in the cylindricality barrel 2, cylindricality compression spring 7 bottom is fixed at 1 up end of collet, and the top of cylindricality compression spring 7 is the free end and offsets with the terminal surface under the shutoff piece, 5 bottoms of jib are fixed with 3 assorted fixture block 4 with bar through-hole, and fixture block 4 is used for running through bar through-hole 3 after the joint in bar counter bore 9, and in order to prevent hoist and mount fixture block 4 and jib 5 break away from, fixture block 4 and jib 5 are the integrated into one piece structure.

In the actual use process, the thickness of the fixture block 4 is greater than or equal to the depth of the strip-shaped counter bore 9, and the thickness of the fixture block 4 is preferably equal to the depth of the strip-shaped counter bore 9, so that the fixture block 4 can be always tightly propped against the top end of the cylindrical compression spring 7 after the fixture block 4 is clamped into the strip-shaped counter bore 9, and the fixture block 4 is prevented from loosening; while not requiring too much force to press the catches 4 in order to snap the catches 4 into the bar-shaped counterbores 9. In some embodiments, a circular plate which can freely move up and down in the cylindrical barrel 2 can be connected to the top end of the cylindrical compression spring 7, and the circular plate can better support the lower end face of the fixture block 4.
