A rotatable joint key ring device, its mounting is cylindrical, and its diameter is not more than the main part and holds the through-hole diameter of mounting, and is not more than the length of connecting piece draw-in groove.

A rotatable joint key ring device, its connecting piece divide into upper portion and lower part, its upper portion has dop and draw-in groove, the dop diameter is not more than the vertical through-hole diameter on the main part, the draw-in groove diameter is less than the dop diameter. The lower part of the clamping head is provided with a through hole for penetrating a key ring. The length of the clamping head part is not more than the depth of the vertical hole of the main body.

A rotatable joint key ring device, its connecting piece dop inserts the vertical trompil mouth of main part after, the mounting passes through the draw-in groove of the horizontal through-hole embedding connecting piece of main part, fixed dop lets it can't deviate from vertical through-hole.

A rotatable joint key ring device, its mounting takes welding or bonding mode to fix with horizontal through-hole after through horizontal through-hole embedding draw-in groove.

Compared with the prior art, the utility model the advantage be: simple structure is practical, and mounting embedding draw-in groove nevertheless thoroughly blocks with the draw-in groove axial plane and dies, and the mounting diameter is not more than draw-in groove length, consequently can realize that the connecting piece is rotatory along its axle center. And the clamping structure can be used on a key ring made of titanium alloy materials, so that the problem that the titanium alloy key ring rotates by 360 degrees is thoroughly solved.

Detailed Description

The utility model provides a rotatable joint key ring device, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following reference is made to the figure and the example the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, 2 and 3, an embodiment of the present invention provides a rotatable snap-fit key ring device, including: the key ring comprises a key ring main body 1, a fixing part 2 and a connecting piece 3, wherein the lower part of the main body is provided with a transverse hole 1-1 for accommodating the fixing part 2 and a transverse hole 1-2 for accommodating a male head 30 of the connecting piece. The fixing piece 2 is cylindrical, the connecting piece consists of a clamping head 30 and a lower part 3-4, and the lower part 3-4 is provided with a through hole 3-4-1 for penetrating a key ring.

In a preferred embodiment, the key ring body 1 is an integrally formed titanium alloy key ring body, the fixed member 2 is an integrally formed titanium alloy fixed member, and the connecting member 3 is an integrally formed titanium alloy connecting member; and then combine the utility model discloses the connecting piece passes through the block structure of mounting and key ring main part, and the built-up mounting process is simple, has thoroughly solved, 360 rotatory difficult problems of titanium alloy key ring.

Further, in the key ring device, as shown in fig. 3, the connecting member 3 includes: the connecting male head 30, a connecting seat 3-4 connected with the connecting male head 30 and a connecting through hole 3-4-1 which is arranged on the connecting seat 3-4 and can be penetrated by a key ring. The lower part of the connecting male head 30 is provided with a cylinder 3-3 with the same diameter as the chuck 3-1, and the connecting piece 3 can have better concentricity and is not easy to shake left and right after being inserted into the vertical hole 1-2 of the main body.

Further, as shown in fig. 4 and 5, in the key ring device of the present embodiment, after the male portion 30 of the connecting element 3 is inserted into the vertical opening 1-2 at the bottom of the main body 1, the fixing element 2 is inserted into the locking groove 3-2 of the connecting element 3 through the transverse opening 1-1 at the bottom of the main body so that the fixing element cannot be removed from the opening 1-2, the fixing element 2 is in contact with the locking groove 3-2 of the locking head 30, but is not locked, and the connecting element 3 can rotate 360 degrees along the axis of the connecting element.
