Detailed Description

The present invention will be described in further detail with reference to examples. As shown in fig. 1 to 6, an innovative rotatable key ring device is composed of a hook 1, an outer shell 2, a spring 3, an inner shell 4 and a fixing piece 5; the hook part consists of an upper ring part 1-1 and a lower straight rod 1-2, an opening 1-3 is arranged at the intersection of the straight rod 1-2 and the upper ring part 1-1 and is used as a hanging access, and a clamping groove 1-4 is arranged at the lower part of the straight rod; the top of the outer shell is provided with a clamping groove 2-1, a through hole 2-2, a reducing hole 2-2-1 and a reducing step 2-2-2, and the step is used for propping the upper part of a spring 3; the inner shell is provided with a counter bore 4-1 and a transverse through hole 4-2 at the lower part, the two holes are crossed, and the outer wall 4-1-1 of the inner shell is used for propping against the lower part of the spring 3; the fixing piece is provided with a straight clamping joint 5-2, an opening 5-1 and an outer ring part 5-3.

Further, as shown in fig. 5, the creative rotatable key ring device has the structure that the lower straight rod part of the hook 1 firstly passes through the through holes 2-2-1 and 2-2 in the outer shell and is sleeved in the spring 3, then is inserted into a counter bore 4-1 in the inner shell 4, the upper part of the spring 3 props against the diameter-variable step 2-2-2, the lower part props against the outer wall 4-1-1 of the inner shell, then, after the fixing piece 5 is unfolded by a tool, the clamping head part 5-2 passes through the transverse through hole 4-2 at the lower part of the inner shell 4 and is embedded into the clamping grooves 1-4 at the lower part of the hook 1 from two sides, the fixed hook 1 cannot be separated from the inner shell 4 and the outer shell 3, and the fixing piece 5 and the inner shell 4 can form 360-degree rotation in the outer shell 2 due to the fact that the clamping head part 5-2 of the fixing piece 5 is not clamped with the surfaces of the clamping grooves 1-4 at the lower part of the hook 1.

Further, as shown in fig. 5, when the inner housing 4 pushes the compression spring 3 upwards, the ring opening 1-3 of the hook 1 can be exposed for hooking, and after the spring 3 is released, the ring slot 1-3 of the hook 1 is pressed into the outer housing slot 2-1 due to the reset of the spring 3, so that the release of the key can be prevented.

Further, in the creative rotatable key ring device, as shown in fig. 5, an inner space 5-4 of the fixing member 5 is used for hanging a key ring.

Compared with the prior art, the utility model the advantage be: through the combination joint of 5 parts of telling, form the key ring structure that can change, it is pleasing to the eye novel.

It is to be understood that the invention is not limited to the above-described embodiments, and that modifications and variations may be effected by one of ordinary skill in the art in light of the above teachings, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
