Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1, the quick-assembly-disassembly fixing device comprises a base 3 and a bolt 1, wherein a spring 4 is fixedly arranged on an inner bottom plate of the base 3, and the top end of the spring 4 is connected with the bottom end of the bolt 1; as shown in fig. 2-3, the plug pin 1 is a conical structure formed by connecting a dome 11 and a column base 12, a supporting shaft 13 is arranged in the middle of the top of the column base 12, and clamping holes 14 are symmetrically formed in the side walls of the column base 12 positioned on two sides of the supporting shaft 13; a torsion spring 2 is arranged in the column base 12, and two torsion arms 23 of the torsion spring 2 are respectively inserted into the clamping holes 14; the torsion arm 23 is connected with a guy cable 5, and the bottom end of the guy cable 5 vertically extends out of the base 3.
Further, as shown in fig. 4, the outer end of the horizontal barrier strip 21 is provided with a retainer ring 22; the clamping hole 14 is a horn hole with a large outer side and a small inner side, and the diameter of the retainer ring 22 is smaller than the outer diameter of the clamping hole 14 and larger than the inner diameter of the clamping hole 14, so that the torsion arm 23 can freely shrink in the clamping hole 14 and finally be clamped in the clamping hole 14.
Further, the pull cable 5 is Y-shaped, the two top ends of the pull cable are respectively connected with the two torsion arms 23 after bypassing the supporting shaft 13, and the bottom ends of the pull cable sequentially penetrate through the column base 12 and the base 3 and then extend out.
Further, as shown in fig. 5, the base 3 is a hollow frame structure, the center of the top end of the base is provided with a pin seat hole 31 which can enable the bolt 1 to freely pass through, and the bottom end of the base is provided with a lower rope hole 32; an upper rope hole 15 is formed in the bottom end of the column base 12.
Further, the central axis of the spring 4 coincides with the central axes of the upper cable hole 15, the pin seat hole 31 and the lower cable hole 32.
The working process of the invention is as follows:
when the pull-down type lifting device is used, only the pull-down type lifting device is required to pull down the inhaul cable, two torsion arms or horizontal baffle strips of the torsion spring are pulled to shrink towards the middle to compress the torsion spring until the retainer ring at the end of the horizontal baffle strip is shrunk to the inside of the clamping hole on the column base and does not fall into the column base, and then the pull-down is continued, the whole bolt is driven to extrude the spring in the base to move downwards in the base until the bolt completely enters the inside of the base.
