Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
As shown in Figure 1, a kind of burglarproof peep hole, comprise lens barrel 1 and be set with described lens barrel 1 the lens barrel overcoat 2 coordinated, described lens barrel 1 is installed together by rotating assemble mechanism with described lens barrel overcoat 2, optical lens is provided with 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 forms the rotatable annulus coordinated with lens barrel 1 and overlap 3, annulus cover 3 is enclosed within lens barrel 1 forward from lens barrel 1 rear end, and hold level with both hands before described annulus cover 3 in or convex in deck 11, be provided with between annulus cover 3 and lens barrel 1 and prevent annulus from overlapping 3 escapements come off from lens barrel 1 front end, the front end being placed in annulus cover 3 due to deck 11 is inner, burglarproof peep hole is arranged on after on security door, before people stands in security door, when directly screwing the deck 11 on lens barrel 1, edge due to deck 11 againsts the inwall of annulus cover 3 and makes people not have origin of force or the point of application, thus lens barrel 3 cannot be rotated, and screw annulus when overlapping 3, annulus cover 3 is movable connections with lens barrel 3, therefore the rotation of annulus cover 3 can not with the rotation of moving lens barrel 3, and annulus cover 3 is enclosed within lens barrel 1 forward from lens barrel 1 rear end, annulus cover 3 is against again on security door, lens barrel 1 and security door have a position-limiting action to annulus cover 3 respectively, even if therefore annulus cover 3 rotates and also can not depart from from lens barrel 1, so ensure that burglarproof peep hole can not be stolen, further, guarantor can not from burglarproof peep hole unlatching burglar-proof door, ensure that the safety of security door.
As shown in Figure 2 and Figure 3, described rotation assemble mechanism comprises the external screw thread 12 being molded over described lens barrel 1 outer wall and the internal thread 22 being molded over described lens barrel overcoat 2 inwall, by the cooperation of internal and external threads 12, is conveniently assemblied on security door by burglarproof peep hole.
Burglarproof peep hole when mounted, lens barrel 1 inserts from security door front end, lens barrel overcoat 2 inserts from security door rear end, by the cooperation of internal and external threads 12, is fixed on by burglarproof peep hole on security door, after installing, deck 11 be placed in annulus cover 3 in, hold level with both hands before deck 11 in or recessed in annulus cover 3, annulus cover 3 boss 31 against deck 11 bottom surface, the bottom surface of annulus cover 3 is against security door, and chuck 21 is against security door rear end.
As shown in Figure 3, described chuck 21 is provided with rotatable light barrier 4.
As Fig. 1, Fig. 4, shown in Fig. 5, described escapement is be arranged on annulus to overlap boss 31 on 3 inwalls, annulus cover 3 is enclosed within lens barrel 1 forward from the rear end of lens barrel 1, base to deck 11 is against on boss 31, the two forms the cooperation in face, Multi-contact can make contact more firm, the position setting of boss 31 is preferably overlapped 3 bases with annulus and is flushed, and boss 31 and annulus overlaps 3 integrally forms, and the through hole that boss 3 is formed, it meets the external diameter being less than deck 11, be greater than the interior diameter of lens barrel 1, can be circular, triangle, square, so, after annulus cover 3 installs with lens barrel 1, annulus cover 3 before hold level with both hands in or convex under the prerequisite of deck 11, the thickness of maximum guarantee annulus cover 3 is minimum, save material and cost, described lens barrel 1 and described annulus overlap 3 install after, boss 31 can prevent described lens barrel 1 from coming off from described annulus cover 3, in like manner, also can ensure that described annulus cover 3 can not come off from the front end of described lens barrel 1, and can plane bearing be provided with between described annulus cover 3 and deck 11, rotating friction force between further minimizing annulus cover 3 and lens barrel 1, therefore screw annulus cover 3 can not with the rotation of moving lens barrel 1, guarantor stands outside the door and lens barrel 1 can not be screwed out from security door.
Described escapement comprises the interior inclined-plane 32 that the outer inclined-plane 111 of described deck 11 and described annulus overlap 3 inwalls, the largest outer diameter on outer inclined-plane 111 is greater 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 forms 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 cover 3, it is improper to design, can cause therebetween that space is excessive, not realize antitheft effect, also can 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 forms inclined-plane laminating, this kind of structure can realize deck 11 edge and annulus overlap 3 seamless applying, real elimination origin of force or the point of application, realize deck 11 by above-mentioned two kinds of modes and overlap matching both 3 with annulus, form interlocking, prevent from described annulus from overlapping 3 to come off from the front end of described lens barrel 1, plane bearing is provided with the contact position of deck 11 at described annulus cover 3, plane bearing inlay card is on inwall, outer inclined-plane 111 can be avoided stuck with interior inclined-plane 32, and formation is linked, the outside of annulus cover 3 is also designed to inclined-plane, so, people stands outside the door, can only exert a force and annulus cover 3 is rotated in a circumferential direction, and axial power can not be applied to it, and inclined-plane is more attractive in appearance.
Below described by reference to the accompanying drawings embodiment is only the preferred embodiment of the present invention, and the restriction not to protection scope of the present invention, and any improvement done based on the present invention's spirit all ought within scope.
