Description
The utility model relates to a kind of lock, particularly a kind of adjustable cipher mask formula anti-theft alarm lock of thickness of installing.
91208188.0 disclose a kind of password Pickproof alarm door lock in number patent application, its design feature is that existing common door lock and encryption apparatus organically are joined together, to reach the purpose of burglar alarm.Its basic structure is that the encryption apparatus panel is provided with dialer, dialer is connected by two inboard combination disk of rotating shaft and axle sleeve and door respectively and can rotates respectively, on two combination disk, have the tongue mouth, upwards draw company at existing Door-lock bolt position and go out an interlock bent plate, when key takes out dead bolt to pass when moving, the plate that then drives on the interlock bent plate moves as level of synchronization, if the tongue mouth on the combination disk turns to and during the corresponding insertion position of the plate of the bent plate that links, then can make the plate insertion or deviate from the tongue mouth, unblank or locked purpose and reach, if institute is not right to password, even there is key to be difficult to unblank yet.
Though this cipher anti theft door lock has the advantage of checking the number and unblanking, but still exists following deficiency:
1. because dialer is directly exposed to the external side of door, make the professional criminal release of checking the number easily.
2. its warning is to rely on travel switch and contact to report to the police, if alarm is destroyed in advance, does not then have the warning effect.
3., then can't realize timely warning, because between interlock bent plate and combination disk, the interlock warning device is not set if the criminal does not have the release of purpose check mark.
4. because its encryption apparatus housing is directly to be connected and fixed with inboard panel, it is installed width and fixes, that is, the single specification door that only is suitable for 40 millimeters thick uses, the actual (real) thickness that can not fit door carries out correspondence adjustment, has limited the scope of application of this lock widely.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, applicable to difference thickness is installed and provide a kind of, is provided with and has or not purpose check mark and tamper, sled alarm and the cipher mask formula anti-theft alarm lock of dialer protective cover interlock.
The purpose of this utility model is to be realized by following technical scheme: existing to dialer outer hinge one protective cover, the protective cover free end is connected with lock pin, pull bar with the key interlock in lock pin and the encryption apparatus housing links, be provided with burglar alarm in the drop front bottom, warning feeler lever and contact in the alarm are connected with outer guide line respectively, the outer guide line other end links to each other with the interior contact and the plate of warning device respectively, drop front can pull out or push and be connected with the inside plate by bolt along the encryption apparatus housing, adjust the different needs that thickness is installed to reach, the setting of protective cover and warning device has prevented check the number release and tear the possibility of pounding warning device open of robber.
Therefore remarkable result of the present utility model is:
1. it is adjustable that thickness is installed, and has big accommodation.
2. have the check the number characteristics of release and hidden combination disk of robber that prevent.
3. have multiple trigger-type warning function, theftproof, safety are improved.
4. has the interlock that combination disk and key combine and just can unblank.
Concrete structure of the present utility model is realized by the following examples and accompanying drawing thereof.
