Description
Technical field
This utility model relates to opal, particularly relates to Anti-dismantling opal.
Background technology
Opal is being commonly called as of peephole, is looked out by peephole from indoor, can see clearly in the range of the angle of visual field is about 120 degree outdoors
All scenes, and if from cannot be seen anything of indoor outdoors by peephole. at the gate in public housing or private residence etc.
On, load onto this mirror, for the antitheft of family and safety, certain effect can be played.Now with opal, including lens barrel and cylinder
Body, is provided with optical lens in lens barrel, during installation, inserted in opal preformed hole from outer side of door by lens barrel, and cylinder is opal inside door
Inserting in preformed hole, cylinder and lens barrel are connected by threaded engagement.Therefore, when rotating lens barrel outdoors, lens barrel can be dismantled
Get off, and then destroy opal, destroy the anti-theft of antitheft door, and opal is easily lost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of safety, anti-theft effect substantially, cannot tear open outdoors
The Anti-dismantling opal removed.
For solving above-mentioned technical problem, the technical solution of the utility model is: Anti-dismantling opal, including being threaded in one
The lens barrel risen and cylinder, described lens barrel closes on described cylinder one end and is provided with cannelure, and card has backplate in described cannelure, described in protect
Plate is fixedly mounted in the shop front；Described backplate is provided with U-lag, and described cylinder is positioned at the U-lag of described backplate, on described backplate
It is provided with observation port with corresponding position, described cylinder position；Described cylinder is away from the U of shop front one end with the described backplate being provided with observation port
Distance between shape arm is less than described cylinder and the screwing length of described lens barrel；Described lens barrel is provided with lens mounting seat, described
Mirror mounting seat is provided with several anti-rotation boss, and several described anti-rotation boss are uniformly arranged along the circumference of described lens barrel.
As preferred technical scheme, described anti-rotation boss is along the outer wall extending radially to described lens barrel of described lens barrel.
As preferred technical scheme, described cylinder is provided with stairstepping spline groove, is provided with stud in described spline groove, with
The corresponding described anti-rotation boss of described spline groove location is provided with spline screwed hole, described stud through described spline groove and with institute
State spline screwed hole to screw, described stud and described spline hole screw direction and described lens barrel and described cylinder screw direction
On the contrary.
Owing to have employed technique scheme, Anti-dismantling effect of the present utility model is obvious, cannot rotate opal outdoors
Dismantling, even if existing the situation of lens barrel partial destruction outdoors, not falling out owing to cylinder is stuck between backplate and the shop front,
The opal hole of the shop front still keeps sealing state, plays anti-theft effect.Stud screws on anti-turntable, further enhances spline
Effect, it is to avoid dismantle outdoors.
This utility model Anti-dismantling is effective, and anti-theft is strong；Simple in construction, easy to use, well solve opal and make
By safety issue present in process, improve the reliability of opal.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, before not paying creative work
Put, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the side view of Fig. 1.
In figure: the 1-shop front, 2-stud, 3-cylinder, 4-backplate, 5-cannelure, 6-U shape groove, 7-lens mounting seat, 8-mirror
Cylinder, 9-installing hole, 10-anti-rotation boss, 11-observation port, 12-spline groove.
Detailed description of the invention
As depicted in figs. 1 and 2, Anti-dismantling opal, including the lens barrel 8 being threaded togather and cylinder 3.Described lens barrel 8
Closing on described cylinder 3 one end and be provided with cannelure 5, in described cannelure 5, card has backplate 4, described backplate 4 to be fixedly mounted on the shop front 1
On.Described backplate 4 is provided with U-lag 6, and described cylinder 3 is positioned at the U-lag 6 of described backplate.With described cylinder 3 on described backplate 4
Corresponding position, position is provided with observation port 12.Described cylinder 3 away from shop front one end and the described backplate being provided with observation port 11 U-shaped arm it
Between distance less than described cylinder 3 and the screwing length of described lens barrel 8.Described lens barrel 8 is provided with lens mounting seat 7, described lens
Mounting seat 7 is provided with several anti-rotation boss 10, and several described anti-rotation boss 10 are uniformly arranged along the circumference of described lens barrel 8.Described
Anti-rotation boss 10 is along the outer wall extending radially to described lens barrel 8 of described lens barrel 8.Increase the intensity of anti-rotation boss 10, strengthen anti-
Turn effect.Reserved lens barrel 8 installing hole 9 in the shop front 1, the shape of installing hole 9 adapts with the shape of lens barrel 8 and anti-rotation boss 10.
If existing the situation of the partial destruction outdoors of lens barrel 8, do not fall out owing to cylinder 3 is stuck between backplate 4 and the shop front 1, the shop front
Opal hole still keep sealing state, play anti-theft effect.
Described cylinder 3 is provided with stairstepping spline groove 12, is provided with stud 2 in described spline groove 12, with described spline groove 12
