Description
Technical field
This utility model is related to a kind of anti-theft door fittings, particularly a kind of Anti-dismantling cat being arranged on use on antitheft door
Eye.
Background technology
Outwards observe outdoor situations it is ensured that the safety of the indoor person and property for the ease of indoor, antitheft door is installed cat
Eye has become one of important accessory of indoor security.But connecting tube is to be coordinated by internal and external threads after the preceding thread pipe of common opal
Fixing, lawless person is easy to being backed out preceding thread pipe using simple tool outdoors and removes opal, and this just gives lawless person
There is opportunity, resident's person and property have potential safety hazard.Chinese patent notification number CN 104131769 B discloses one kind
Burglarproof peep hole, the lens barrel overcoat including lens barrel and with the suit cooperation of described lens barrel, described lens barrel is passed through with described lens barrel overcoat
Rotation assemble mechanism is installed together, and puts and be additionally provided with outside described lens barrel with described lens barrel outside described lens barrel and described lens barrel
Set prevents the clamping mechanism that described lens barrel screws out from described lens barrel overcoat after installing.This burglarproof peep hole, parts are few, cost
Relatively low, easy for installation, time saving and energy saving.But there is problems with use：Because screens piece directly becomes from lens barrel overcoat
Type forms, and the elastic reset requirement to screens piece is higher, usually can occur can not reset because of screens piece elastic deformation, lead to card
Bit slice cannot coordinate stop bit with chuck, does not have due anti-theft function.Two is due to being fitted without shading cover, and lawless person can
Can there is potential safety hazard from the situation directly spying on interior outdoors by anti-opal sight glass.For this reason, many manufacturers and
Knowledgeable people is researched and developed for the problems referred to above, but not yet has more rational product to emerge so far.
Content of the invention
For the above-mentioned problem overcoming existing Anti-dismantling opal to exist, the purpose of this utility model is to provide a kind of structure letter
The Anti-dismantling opal that list is reasonable, easy to install, firm and reliable connection, retaining effect are good.
This utility model solves the technical scheme that adopted of above-mentioned technical problem, it include protecgulum, front mirror, preceding thread pipe,
Mirror, rear connecting tube, bonnet afterwards, described protecgulum is fixed on preceding thread pipe, and bonnet is fixed in rear connecting tube, on preceding thread pipe
It is provided with external screw thread, rear connecting tube is provided with female thread and the interior pipe with diameter greater than preceding thread pipe external thread diameter, connects afterwards
Gutron is crossed female thread and is fixed on preceding thread pipe with external screw thread cooperation, is provided with stopping device between preceding thread Guan Yuhou connecting tube,
This stopping device includes back stop slot, retaining jump ring, and back stop slot is disposed longitudinally on preceding thread pipe, on the interior pipe of rear connecting tube
It is provided with retaining jump-ring slot, retaining jump ring is arranged on retaining jump-ring slot, one end of retaining jump ring is provided with retaining jump ring head, locking card
The distance of spring cephalic par to centrage is less than back stop slot to the distance of centrage, retaining jump ring cephalic par to root direction and rear company
Adapter precession direction is consistent, and during rear connecting tube precession, retaining jump ring head is pressed against retaining jump-ring slot by preceding thread pipe and produces deformation,
When connecting tube retreats afterwards, retaining jump ring cephalic par is conflicted on the cell wall of back stop slot.
The further scheme of this utility model, described preceding thread pipe is provided with three equally distributed back stop slots, and back stop slot is
Trough with straight angle.
The further scheme of this utility model, described preceding thread pipe is provided with front mirror centring ring, front mirror be arranged on protecgulum with
Between front mirror centring ring.
The further scheme of this utility model, described preceding thread pipe is provided with rear mirror centring ring, and it is fixed that rear mirror is arranged on rear mirror
Position circle is upper and is fixed by jump ring.
The further scheme of this utility model, described after cover rotatable shading cover be provided with by hinge, hinge sets
There is O-shaped packing ring, shading cover is provided with turning handle.
After said structure, compared with prior art have the following advantages and effect：One is that installation is simple and convenient, during installation
Because retaining jump ring cephalic par to root direction is consistent with rear connecting tube precession direction, during rear connecting tube precession, retaining jump ring head is subject to
Preceding thread pipe is pressed against retaining jump-ring slot and produces deformation, does not have retaining effect, as long as rotation bonnet can install fixation.Two are
Because when rear connecting tube retreats, retaining jump ring cephalic par is conflicted on the cell wall of back stop slot, so lawless person is torn open using pipe vice
Unload and also cannot rotate during protecgulum, substantially increase theftproof performance.Three be due to after cover and be provided with rotatable shading cover, so not
Method molecule cannot be using anti-opal sight glass from the situation directly spying on interior outdoors, thus eliminating from directly spying on interior outdoors
Potential safety hazard.
