Abstract
The invention relates to an anti-theft cat eye. By the adoption of the anti-theft cat eye, the problem that a cat eye is easy to dismount is solved. The anti-theft cat eye comprises a lens barrel and a lens barrel jacket which is matched with the lens barrel in a sleeving mode. The lens barrel and the lens barrel jacket are installed together through a rotating assembly mechanism. An optical lens is arranged in the lens barrel. A clamping base is arranged at the front end of the lens barrel. The rear end of the lens barrel jacket is provided with a clamping table. A circular ring sleeve is arranged on the lens barrel, and the circular ring sleeve is in rotatable fit with the lens barrel. The circular ring sleeve is arranged on the lens barrel in a sleeving mode from the rear end of the lens barrel to the front end of the lens barrel, and the front end of the circular ring sleeve is flush with or protrudes out of the clamping base. An anti-disengagement mechanism used for preventing the circular ring sleeve from being disengaged from the front end of the lens barrel is arranged between the circular ring sleeve and the lens barrel. By the adoption of the circular ring sleeve, people outside a door cannot unscrew the lens barrel, the lens barrel is prevented from being unscrewed out of the anti-theft door, and thus an anti-theft function is achieved.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
nullAs shown in Figure 1，A kind of burglarproof peep hole,It is set with the lens barrel overcoat 2 coordinated including lens barrel 1 and with described lens barrel 1，Described lens barrel 1 and described lens barrel overcoat 2 are installed together by rotating assemble mechanism，It is provided with optical lens in lens barrel 1，Described lens barrel 1 front end is provided with deck 11，Described lens barrel overcoat 2 rear end is provided with chuck 21，Described lens barrel 1 is provided with and constitutes the rotatable annulus coordinated set 3 with lens barrel 1，Annulus set 3 is enclosed within forward lens barrel 1 from lens barrel 1 rear end，And hold level with both hands before described annulus set 3 in or convex in deck 11，The escapement preventing annulus set 3 from coming off it is provided with from lens barrel 1 front end between annulus set 3 and lens barrel 1，Owing to deck 11 is placed in inside the front end of annulus set 3，After burglarproof peep hole is arranged on antitheft door，Before people stands in antitheft door，When directly screwing the deck 11 on lens barrel 1，People is made not have impetus or the point of application owing to the edge of deck 11 againsts the inwall of annulus set 3，Thus lens barrel 3 cannot be rotated，And screw annulus when overlapping 3，It is movable connection with lens barrel 3 that annulus overlaps 3，Therefore the rotation of annulus set 3 will not with the rotation of moving lens barrel 3，And annulus set 3 is enclosed within forward lens barrel 1 from lens barrel 1 rear end，Annulus set 3 is against again on antitheft door，Annulus is overlapped 3 by lens barrel 1 and antitheft door respectively a position-limiting action，Even if therefore annulus set 3 rotation departs from without from lens barrel 1，So ensure that burglarproof peep hole will not be stolen，Further，Warrantor will not from burglarproof peep hole unlatching burglar-proof door，Ensure that the safety of antitheft door.
As shown in Figure 2 and Figure 3, described rotation assemble mechanism includes the external screw thread 12 being molded over described lens barrel 1 outer wall and the female thread 22 being molded over described lens barrel overcoat 2 inwall, by the cooperation of internal and external threads 12, is conveniently assemblied on antitheft door by burglarproof peep hole.
Burglarproof peep hole is when mounted, lens barrel 1 inserts from antitheft door front end, lens barrel overcoat 2 inserts from antitheft door rear end, by the cooperation of internal and external threads 12, is fixed on antitheft door by burglarproof peep hole, after installing, deck 11 be placed in annulus set 3 in, hold level with both hands before deck 11 in or recessed in annulus overlap 3, annulus set 3 boss 31 against deck 11 bottom surface, the bottom surface of annulus set 3 is against antitheft door, and chuck 21 is against antitheft door rear end.
As it is shown on figure 3, described chuck 21 is provided with rotatable light barrier 4.
nullSuch as Fig. 1、Fig. 4、Shown in Fig. 5，Described escapement is be arranged on the boss 31 that annulus overlaps on 3 inwalls，Annulus set 3 is enclosed within forward lens barrel 1 from the rear end of lens barrel 1，Base to deck 11 is against on boss 31，The two constitutes the cooperation in face，Multi-contact can so that contact be more firm，The position setting of boss 31 is preferably overlapped 3 bases with annulus and is flushed，And boss 31 is integrally formed with annulus set 3，And the through hole that boss 3 is formed，It meets the overall diameter less than deck 11，Interior diameter more than lens barrel 1，Can be circular、Triangle、Square，So，After annulus overlaps 3 and lens barrel 1 installs，Annulus set 3 before hold level with both hands in or convex under the premise of deck 11，Farthest ensure that the thickness of annulus set 3 is minimum，Save material and cost，After described lens barrel 1 installs with described annulus set 3，Boss 31 is prevented from what described lens barrel 1 came off from described annulus set 3，In like manner，Also can guarantee that described annulus set 3 will not come off from the front end of described lens barrel 1，And plane bearing can be provided with between described annulus set 3 and deck 11，Reduce the rotating friction force between annulus set 3 and lens barrel 1 further，Therefore screw annulus set 3 will not with the rotation of moving lens barrel 1，Warrantor stands outside the door and will not screw out from antitheft door by lens barrel 1.
Described escapement includes the outer inclined-plane 111 of described deck 11 and described annulus overlaps the interior inclined-plane 32 of 3 inwalls, the largest outer diameter on outer inclined-plane 111 is more than the minimum interior diameter on interior inclined-plane 32, outer inclined-plane 111 coordinates with interior inclined-plane 32, can be as shown in Figure 6, the largest outer diameter on outer inclined-plane 111 presses close to the minimum interior diameter on interior inclined-plane 32, the two constitutes the radial direction laminating of line, the interior bevel angle of the outer bevel angle of this kind of structural limitation deck 11 and annulus set 3, it is improper to design, can cause therebetween that space is excessive, it is achieved not antitheft effect；Can also be as shown in Figure 7, the largest outer diameter on outer inclined-plane 111 presses close to the maximum inner diameter on interior inclined-plane 32, the two constitutes inclined-plane laminating, this kind of structure can realize the seamless applying of deck 11 edge and annulus set 3, real elimination impetus or the point of application, realize deck 11 by above two mode and overlap matching both 3 with annulus, form interlocking, prevent described annulus set 3 from coming off from the front end of described lens barrel 1, it is provided with plane bearing in the contact position of described annulus set 3 with deck 11, plane bearing card is embedded on inwall, outer inclined-plane 111 can be avoided stuck with interior inclined-plane 32, and constitute and be linked, the outside that annulus overlaps 3 is also designed to inclined-plane, so, people stands outside the door, can only exert a force and rotate in a circumferential direction so that annulus overlaps 3, and it can not be applied axial power, and inclined-plane is more attractive in appearance.
Being only the preferred embodiment of the present invention above in association with the embodiment described by accompanying drawing, and not restriction to protection scope of the present invention, any improvement done based on present invention spirit all ought within scope.
