Specific embodiment
It is further illustrated below in conjunction with embodiment shown in the drawings.
As shown in Fig. 1 to Fig. 3, a kind of spectacle frame anti-theft fastener by shell, is mounted on the intracorporal retaining mechanism of shell and frequency
Element 10 forms.The retaining mechanism includes revolving part 3, screw element 4, latch part 6 and lock core component.
The shell is made of plastic lid 9 and plastic bottom 11, and plastic lid and the conjunction of plastic bottom buckle are connected as one.Plastic bottom system
There is recessed cavity, cavity bottom center offers perforation 11-1；It is an opening, opening that plastic, which is covered corresponding to the position of cavity,
Diameter is slightly smaller than cavity diameter；The retaining mechanism inserts embedding be mounted in opening and cavity.The plastic lid and plastic bottom are made
The extended segment that oriented side extends；The frequency element is installed between two extended segments.
The revolving part is spliced by left housing 3-1 and right shell 3-2；Left housing and right shell upper end laterally offer be used for respectively
Insert the glasses jack 3-3 of spectacle frame；It is (perpendicular along revolving part axis direction that the inner wall of left housing and right shell is formed respectively with guidance screw element
Histogram to) lifting guide groove 3-6；The outer wall lower part of left housing and right shell is formed respectively with block 3-5, and the block is located at plastic lid
Lower section, to limit the movement of revolving part axis direction.The bottom end of the revolving part is additionally provided at least one unidirectional tooth 3-4.
The latch part includes integrally formed outer ring 6-1 and inner ring 6-2, and outer ring is coaxially arranged with inner ring and is spaced one section
Gap；The top of the outer ring is formed with the unidirectional gear ring 6-3 with the unidirectional tooth engagement；It is formed with radially at the top of the inner ring
The slot 6-4 of direction perforation；The cavity be connected vertically is also provided in inner ring, shrink mouth shape is made in the top of cavity, for pacifying
Fill lock core component；The screw element 4 is the cylindrical body of axis vertical arrangement, is inserted to the lower rotatable of the screw element embedded in described
In gap, the inner wall production of screw element has internal screw thread 4-1, which arranges around tubular body axis helical form.
The bottom of circle is also set up there are two downwardly projecting elastic head 6-5, and elastic head is resisted against the bottom of upper casing cavity, from
And certain upward elastic force is applied to latch part, guarantee that not will drive latch part when revolving part rotates forward rotates together.
The lock core component includes two steel balls 5, lock core 7 and lock core spring 8.Two steel balls are mounted in slot and can be
It is rolled in slot.The lock core is made of iron material, and the tapered end of lock core upper end is along the axis direction insertion cavity of latch part
The necking in portion and the inner end for being resisted against two steel balls, for two steel balls under the squeezing action of tapered end, outer end is ejected slot simultaneously
It is engaged with the internal screw thread 4-2 for being provided with screw element inner wall.Lock core lower end passes through lock core spring and extends to the perforation 11- at plastic bottom
In 1, to guarantee that lock core can be along latch part axial-movement.
The glasses jack top inner wall of the revolving part is fixed with viscose part 1, and viscose part bottom is fixed with non-slip mat 2.Institute
The top surface for stating screw element is fixed with non-slip mat；The screw element outer wall is additionally provided with the guide pad 4-1 matched with guide groove.
The radius of the slot is slightly larger than the radius of steel ball, so that steel ball rolls in slot；The radius of the steel ball is big
In the radius of necking, to prevent steel ball from falling into the cavity of inner ring.
The working principle of the utility model is:
In use, pulling spectacle frame later rotates forward revolving part by the glasses jack of spectacle frame insertion revolving part,
Since the guide pad of screw element is stuck in the guide groove of revolving part, screw element rotates together (revolving part and latch together with revolving part
Part is by unidirectional tooth engagement, and when revolving part rotates forward, latch part is motionless, and unidirectional tooth can be along unidirectional ring gear against rotation), Er Qieyou
It is protruded to the outer diameter from the slot on latch part inner ring top under the squeezing action of tapered end in two steel balls, and and screw thread
The internal screw thread of part engages；Latch part inner ring and steel ball are equivalent to screw rod at this time, and screw element can be along guide groove while rotation
It rises, and then compresses spectacle frame.Opposite direction rotate revolving part when, under the action of unidirectional tooth, revolving part, screw element, latch part and
Steel ball rotates together, so as to adjust the direction of spectacle frame.
When unlocking, lock core is sucked in magnetic lockaid gun 12, and the tapered end of lock core upper end moves downward the sky of retraction latch part inner ring
Chamber and relieve the press to two steel balls (while lock core spring by lock core push shrink), lock core lower end passes through housing bottom
Perforation stretch out hull outside, two steel balls immediately departing from engaging for internal screw thread 4-1 and roll into slot center, screw element edge
Guide groove slide downward and unclamp spectacle frame, complete to unlock.
When housing bottom is by external impacts, can not be stretched out since support is supported by exterior object simultaneously in tapered end bottom end
Hull outside, thus the tapered end of lock core upper end still maintains the press to two steel balls, can not be detached from two steel balls, to prevent
Violence unlocking.
Finally it should be noted that the above enumerated are only specific embodiments of the present invention.It is clear that the invention is not restricted to
Above embodiments can also have many variations.Those skilled in the art can directly lead from present disclosure
Out or all deformations for associating, it is considered as protection scope of the present invention.
