DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 7 As shown, a quick-connect lifting ring is provided by an embodiment of the present invention, comprising a ring portion 1 and a rod portion 2 arranged on the ring portion 1, the ring portion 1 comprising a movable mechanism 11, the movable mechanism 11 comprising a mounting groove 111, a mounting seat 112 and a rotating shaft 113, the mounting seats 112 being arranged on both sides of the mounting groove 111, the rotating shaft 113 being movably arranged in the mounting groove 111, one end of the rotating shaft 113 being movably sleeved with a torsion spring 115, a spring groove 116 being fixedly provided on the inner side of the mounting seat 112 on one side of the mounting groove 111 corresponding to the torsion spring 115, and a clamping block 117 being provided at both ends of the torsion spring 115, the rod portion 2 comprising a fixing mechanism 21, the fixing mechanism 21 comprising a gasket 211 and a pin hole 212, the gasket 211 being movably sleeved on one end of the rod portion 2, and a fixing buckle 213 being inserted into the pin hole 212.

[0025] In one embodiment of the present utility model, the rod portion 2 and the ring portion 1 are movably hinged through the rotating shaft 113, which facilitates the installation and connection of the hanging ring. The torsion spring 115 is provided in combination with the clamping block 117, so that the closing of the rod portion 2 can be conveniently controlled during use. The pin hole 212 is provided in combination with the fixing buckle 213, so that the rod portion 2 can be limited and fixed to prevent it from falling out. The gasket 211 is provided to increase the fixing area, and the rod portion 2 can be further limited and fixed.

[0026] In an example of the present invention, during use, the fixing buckle 213 is first removed from the pin hole 212, and then the gasket 211 is removed. At this time, the rod 2 can rotate freely around the shaft hole 114 via the rotating shaft 113. When the rod 2 is rotated to open, the torsion spring 115 is squeezed by the block 117 and twisted to store elastic potential energy to connect the sling. When the rod 2 is closed, the elastic potential energy in the torsion spring 115 is released to drive the rod 2 to rotate and reset. Then the gasket 211 is put on, and the fixing buckle 213 is inserted into the pin hole 212 to complete the limit fixation of the rod 2.

[0027] like Figures 1 to 5 As shown in FIG. 1 , as a preferred embodiment of the present invention, the ring portion 1 is configured to be horseshoe-shaped, the mounting seat 112 and the ring portion 1 are integrally cast, and a movable groove 12 is fixedly provided at one end of the ring portion 1 .

[0028] Furthermore, the rotating shaft 113 is configured as a stepped shaft with different diameters at both ends. Shaft holes 114 matching the diameters of the two ends of the rotating shaft 113 are fixedly provided in the two mounting seats 112 , and both ends of the rotating shaft 113 are movably located in the shaft holes 114 .

[0029] In one embodiment of the present invention, the mounting seat 112 and the ring portion 1 are integrally cast to improve the overall strength of the ring portion 1 , and the rotating shaft 113 is configured as a stepped shaft to facilitate installation of the rotating shaft 113 .

[0030] like Figures 2 to 5 As shown in FIG. 1 , as a preferred embodiment of the present invention, the torsion spring 115 is movably mounted on the thin end of the rotating shaft 113. The spring slot 116 is configured as a cylindrical cavity. The inner diameter of the spring slot 116 is larger than the outer diameter of the torsion spring 115. The torsion spring 115 and one end of the rotating shaft 113 are both movably positioned within the spring slot 116. The clamping block 117 is configured as a block-like structure. Two clamping blocks 117 are fixedly mounted at the junction of the thin and thick ends of the rotating shaft 113 and inside the spring slot 116, respectively.

[0031] In one example of the present invention, the torsion spring 115 is limited by the provided block 117, which can facilitate the control of the closing of the rod 2 during use, and the torsion spring 115 can be conveniently accommodated and facilitated by the provided spring groove 116 to facilitate the movement of the torsion spring 115.

[0032] like Figure 7 As shown in FIG. 1 , as a preferred embodiment of the present invention, the movable groove 12 is configured as a strip-shaped groove, with one end of the rod 2 movably positioned within the movable groove 12. A pin hole 212 radially extends through the rod 2, and the cross-sectional dimensions of the fixing buckle 213 match the inner diameter of the pin hole 212. A mounting block 22 is fixedly disposed on the rod 2 at a position corresponding to the mounting groove 111. A mounting hole 23 is fixedly disposed within the mounting block 22 corresponding to the rotating shaft 113, and the mounting hole 23 closely mates with the rotating shaft 113.

[0033] In one example of the present invention, the movable groove 12 is provided to facilitate the movement of the rod 2 and limit the range of movement of the rod 2. The pin hole 212 is provided in combination with the fixing buckle 213 to limit and fix the rod 2 to prevent it from falling out. The gasket 211 is provided to increase the fixing area and further limit and fix the rod 2.
