Description
Technical field
The present invention relates to a kind of cat eye device, relate in particular to a kind of burglarproof peep hole device with anti-theft function.
Background technology
Opal, also known as peephole, is installed in a kind of compact optical instrument on the door of house family, it is simple to resident observes outdoor situation.Cat eye device of the prior art, hollow base and hollow holders are to be threaded connection mode to be arranged in the door opening of door, so can at rotary hollow base outdoors, hollow base can be separated with hollow holders, thus hollow base is pulled down from door opening, not only it is easily lost hollow base and hollow holders, and thief uses the internal enabling handle of tool drives or other door openers easily by the door opening on door, being opened by door outdoors and then burglary, in turn result in the property loss of user.
Video monitoring opal disclosed in this Chinese patent literature CN203515273U records cat eye device, described cat eye device comprises hollow base and a hollow holders, the front end of described hollow base is stretch out the expansion section on front side of the door opening of door, there is outside rear end externally threaded external thread part, the rear end of described hollow holders is stretch out the flange on rear side of the door opening of door, and the front end of described hollow holders is the internal thread part having and being engaged in described externally threaded female thread；Wherein, internal thread part being axially provided with skewed slot, and the stage casing of internal thread part is provided with annular groove, be provided with an end and be bent to form the C-type steel circle of a slip block end in annular groove, slip block end is laterally positioned in skewed slot place.Thus, behind hollow pipe portion with hollow holders threaded engagement, once external staff wants to reversely rotate hollow pipe portion, then friction is made slip block end towards passage outside the inclined-plane of skewed slot by external thread part, thus stuck screw-threaded engagement, makes hollow pipe portion can not take out from outside.
But the cat eye device in above-mentioned patent documentation has the following disadvantages: 1) in this cat eye device, C-type steel circle needs to be arranged in the annular groove on described internal thread part, and the slip block end of C-type steel circle needs to be horizontally installed in skewed slot place, this kind of fit system of C-type steel circle and internal thread part, C-type steel circle is installed cumbersome, if and C-type steel circle does not have installation to put in place, annular groove will be supported out when the mutual threaded engagement in internal and external threads portion by the end of external thread part, and then anti-theft function cannot be played；2) in this cat eye device, once after hollow pipe portion and hollow holders threaded engagement, hollow pipe portion not only can not be screwed out from outside, nor hollow holders can be screwed out from inside, because when reversely rotating hollow holders, friction is made slip block end towards passage outside the inclined-plane of skewed slot by external thread part equally, thus stuck screw-threaded engagement makes, hollow holders can not be taken out from inside；So when user is in installation process, hollow holders and hollow pipe portion threaded engagement generation meshing onfines, cause when the cat eye device after assembling deforms, have no idea again to coordinate hollow holders and hollow pipe portion；Also or when not installing, have people's imprudence by hollow holders with hollow pipe portion spiral together with, will be unable to by hollow holders and hollow tube portion from, and then cause part-waste.
Summary of the invention
For this, the technical problem to be solved is in that the theft-prevention structure in cat eye device of the prior art, it is not easy to assembling, and while hollow pipe portion and hollow holders threaded engagement, realize locking, the assembling being not easy to hollow pipe portion and hollow holders regulates, and then provide one be easily assembled, and can carry out between hollow pipe portion and hollow holders assembling regulate burglarproof peep hole device.
For solving above-mentioned technical problem, a kind of burglarproof peep hole device of the present invention, it includes the hollow inner side pipe in the opal preformed hole that can stretch on described door by the inner side of door, the hollow outside pipe in described opal preformed hole and with objective carrier can be stretched into by the outside of described door, and setting the attachment structure the two being connected between described hollow inner side pipe with described hollow outside pipe, and between described hollow inner side Guan Yumen and/or described hollow outside Guan Yumen, it is provided with the position limiting structure that the described hollow inner side pipe that restriction is integrally connected occurs the axial direction along described opal preformed hole to move with described hollow outside pipe；Described attachment structure includes some circles the first pawl being molded over the inserting end end of described hollow inner side pipe or described hollow outside pipe, the some circles being molded over the inserting end end of described hollow outside pipe or described hollow inner side pipe are suitable for being engaged the second pawl of back-off with described first pawl, axially it is molded on the inserting end sidewall of described hollow inner side pipe or described hollow outside pipe and is easy to described first pawl and at least one open slot that described second pawl matches, and it is set on the described hollow inner side pipe or described hollow outside pipe that are provided with described open slot, move the cuff of mouth of pipe banding by being provided with described open slot to described open slot direction under the promotion of installation tool.
