Description
Technical field
The present invention relates to security door technical field of safety devices, particularly relating to is a kind of opal assembly preventing carrying out from outside dismantling.
Background technology
Opal, also known as peephole, is a kind of being arranged on a body so that observe the compact optical instrument of situation outdoors.Existing opal assembly mainly comprises lens barrel and is set with lens barrel the lens barrel overcoat coordinated, optical lens is provided with in lens barrel, lens barrel and lens barrel overcoat are together by a threaded connection, when opal assembly is installed, in door, lens barrel overcoat is fastened on door by clamp nut, by lens barrel from the preformed hole be inserted into outdoors a body, the lens of lens barrel towards outdoors, are assembled together making lens barrel and lens barrel overcoat be threaded connection by the deck rotating lens barrel outdoors.Although easy for installation, but because lens barrel and lens barrel overcoat are assembled together by simple helicitic texture, be easy to utilizing simple instrument to be backed out by lens barrel outdoors, thus remove opal, the preformed hole exposed on door, therefore such mode also leaves potential safety hazard.
For this reason, propose some opal assemblies in prior art and solve the Anti-dismantling of opal, antitheft problem.
Such as, a kind of Anti-dismantling opal disclosed in No. 201220555770.9 Chinese patent, comprises minute surface fore-end, draw-in groove, base, the snap ring of band screw rod.The screw rod of minute surface fore-end, through base, the screw rod of minute surface fore-end has draw-in groove, draw-in groove is equipped with snap ring.Minute surface fore-end and base are hollow structure.This opal when mounted, base is put into opal hole inside door, by screw rod from empty through opal, make screw rod pass base and its afterbody is exposed in the air from opal, screw rod expose inner side part form draw-in groove, be installed to by snap ring in draw-in groove, the diameter due to snap ring is greater than the diameter in opal hole, make screw rod from extracting out outdoors, thus antitheft left and right cannot be played.But this burglarproof peep hole needs the snap ring of special configuration, and is need to install snap ring separately in installation, install comparatively complicated.
And for example, a kind of burglarproof peep hole disclosed in No. 201420236763.1 Chinese patent application, comprises the inside and outside sleeve pipe linked together by internal and external screw thread, and the inside and outside wall of described inside and outside sleeve pipe is respectively equipped with some inside and outside wall longitudinal flutings, in all, in outer wall longitudinal fluting, have one at least to interior, the opening of outer wall longitudinal fluting aligns and is inserted with locking rod, like this, when interior, outer tube is respectively from door, outer reeve opal preformed hole in passing through, external screw thread connects to be screwed to when almost tightening makes a couple wherein interior, the opening of outer wall longitudinal fluting aligns, then locking rod is inserted in door this internal, in namely lockable in outer wall longitudinal fluting, outer tube, in this case, undesirable just cannot be back-outed by rotary sleeve pipe from door, lay down outer tube, thus cannot steal from outdoors unlocking tool being stretched into opal preformed hole to open door.Similarly, this burglarproof peep hole structure, need the pair of openings of aiming at inside and outside wall longitudinal fluting also to install separately when mounted and insert locking rod, installation process is complicated.
