Specific embodiment
Embodiment one:
Referring to Figures 1 and 2, a kind of packet chain length adjusting buckle, including rotating bar 1 are provided with through-hole in the lower end of rotating bar 1
2, the length direction for being axially perpendicular to rotating bar 1 of through-hole 2 is equipped with mobilizable ring buckle 3 in through-hole 2, ring buckle 3
Cross sectional shape be it is rectangular, the opening 4 passed through for rotating bar 1 is provided in the side of ring buckle 3, the inside of rotating bar 1 along
Its length direction is provided with the threaded hole 5 through the body of rod, the screw rod 6 being threadedly engaged therewith is provided in threaded hole 5, in screw rod
6 upper end is provided with the cross recess for entering for screwdriver, in threaded hole 5 and be located at screw rod 6 lower end and through-hole 2 it
Between be provided with spring 8, be provided with hoodle 7 between spring 8 and through-hole 2, hoodle 7 for being contacted with ring buckle 3, spring 8 it is upper
It holds and (squeezes and contact) with the crimping of the top of hoodle 7 with the crimping of the lower end of screw rod 6 (extruding contacts), the lower end of spring 8.
The principle of the adjusting buckle are as follows: screw rod 6 is tightened by screwdriver, so that screw rod 6 gradually screws in threaded hole 5, herein
Spring 8 is compressed in the process, and spring 8 increases the pressure of hoodle 7, and hoodle 7 gradually compresses ring buckle 3, due to cutting for ring buckle 3
Face shape is rectangular --- i.e. the surface tool of ring buckle 3 is there are four plane, 7 clamping plane of hoodle, at this time to make rotating bar 1 and
Ring buckle 3 relatively rotates, then spring 8 can continue to compress, and the elastic force of spring 8 can hinder the generation of above-mentioned relative rotation,
To play certain locking effect, rotating bar 1 is locked to the angle of some plane perpendicular to ring buckle 3, as long as will
Screw rod 6 is tightened completely, can be completely locked by rotating bar 1.
By twisting screw rod 6, the elastic force of spring 8 is adjusted to moderate, can be achieved with can effectively locking rotating bar 1 and
Rotating bar 1 can be enable to rotate around four faces of ring buckle 3, it is very convenient quick without every time by screwdriver.
The application method of the adjusting buckle are as follows: produce rotating bar 1 from the opening 4 of ring buckle 3, then by two latch closures of packet chain
It is penetrated in ring buckle 3 from the left end of opening 4 and right end respectively, then rotating bar 1 is turned in opening 4, it can be by selected two
A latch closure links together, thus play the role of adjusting packet chain length, it is very convenient quick.
In the present embodiment, to prevent the upper end of spring 8 and the lower end of screw rod 6 from getting loose, it is provided in the lower end of screw rod 6
Taper portion 9, taper portion 9 are inserted into the upper end of spring 8.
In other embodiments, spring 8 and hoodle 7 can be removed, directly compresses ring buckle 3 with the lower end of screw rod 6, only
The lower end surface by screw rod 6 is but needed to be set as plane.
Embodiment two:
Referring to Fig. 3, the difference between this embodiment and the first embodiment lies in: it is provided with and crosses out in the upper end of screw rod 6
Hand twists portion 10.So as to conveniently turn screw rod 6, without external tool.
Embodiment three:
Referring to Fig. 4, the difference between this embodiment and the first embodiment lies in: in each of the position that ring buckle 3 is contacted with hoodle 7
It is provided with the supporting surface 11 of arc-shaped indent at face, the joining place of adjacent two supporting surface 11 is provided with the guidance of arc-shaped evagination
Face 12, guide surface 12 and the natural transition of supporting surface 11.
Such structure makes the hoodle 7 under the premise of not influencing Locking property more suitable when section between each face
Freely.And during hoodle 7 switches between each face, spring 8 is with bigger deformation space --- i.e. hoodle 7 has more
Big stroke can so generate stronger feedback feeling, promote feel when rotating bar 1 rotates.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
