Abstract
The invention relates to a mechanical digital code lock, comprising lock body and lock head. Lock body comprises lock tongue linked with core shaft at least. Lock head contains core shaft, outer unlocked handle linked with core shaft and control parts for core shaft rotary. The control parts contains multiple keystrokes, clip keys relative to keystrokes and linking plate with rectangle ports, round which there is notch. Here the linking plate is set vertically with clip key. There are base with multiple narrow slots, reposition linking plate and multiple springs by which clip key is assembled. Clip key contains main key, secondary key and reposition key. When it is assembled main secondary keys is symmetric in inner side. There is unsymmetrical rectangle notch on the outside.
Description
The present invention relates to a kind of mechanical digital puzzle lock.
At present, Chang Yong coded lock has mechanical type, various ways such as electronic type and electromagnetic type, electronic type and electromagnetic type are subjected to external influence and fault rate height easily, so mechanical code lock is still main privacy lock kind, is widely used in door and window, on safety cabinet and the suitcase.The prior mechanical coded lock is easy to the password that is decrypted, and change is rotated dumb, and can not arbitrarily change password according to user's intention.
The objective of the invention is to overcome the above-mentioned shortcoming of existing machinery coded lock, good confidentiality is provided, the mechanical digital puzzle lock that password can arbitrarily change.
Mechanical digital puzzle lock comprise be installed in respectively outdoors with door in two parts, link to each other by mandrel between them, the interior part of door that is called as lock body comprises dead bolt and the interior unlatching handle that links with this mandrel at least, part is referred to as tapered end outdoors, it controls the position of dead bolt by the rotation of control mandrel, thereby reaches the unlatching of control lock or the purpose of closing.
The present invention is directed to tapered end improves, this improved tapered end comprises the rectangle case type shell, the tapped Assembly rail that is fixedly linked with shell, lay respectively at the mandrel and the outer handle of opening in the inboard and the outside of shell one end, and button control section, this control section comprises: by major key, a plurality of buttons that inferior key and reset key are formed, with button sheet card key one to one, the interlock plate of laying with card key quadrature, slot with a plurality of peripheral notches is arranged on the interlock plate, each recess and button, the position of card key is corresponding, the interlock plate cooperates with tooth plate or rotating disk on being positioned on mandrel, only when the interlock plate can vertically move, mandrel could do not linked plate restriction and rotate, cause at last the lock be opened.When uneasiness is installed key or card keyboard when being in opening and arranging, the interlock plate can along under base-plates surface move; Be subjected to reset key to control the interlock batten that resets; And a plurality of springs that are used for flexibly installing button and card keyboard.But tapered end is randomize card key position (every kind of card key arrangement mode constitutes a kind of password) before assembling, because lock adopts the screw assembling, therefore the user can set up password on their own, in one embodiment of the invention, the card key has 14, its permutation and combination has a variety of, can not accidental centering password.Therefore security performance is fine.
Fig. 1 is the elevation of the tapered end of mechanical digital puzzle lock of the present invention;
Fig. 2 is the interlock plate schematic diagram of installing in the tapered end shown in Figure 1.
Fig. 3 is the schematic diagram based on the operating principle of the reflection card bond structure of tapered end cross section shown in Figure 1 and door lock of the present invention.With to cut open figure different, the not shown concrete cross-section structure of this figure.
As Figure 1-3, tapered end comprises rectangle case type shell 1, and the outer handle 2 of opening is installed on the housing.14 perforates are arranged on the shell, be equipped with in each hole a button 3 wherein the C key be reset key, be equipped with in the enclosure and card hay 8a or the 8b of each button becoming educated through independent study, each card key all with plate 4 and the pedestal (not shown) quadrature of linking.On pedestal, have and the corresponding slit of each card keyboard.On the interlock plate slot is arranged, the hole periphery has and the corresponding recess 5 of card key.Also have upper 6 that cooperates with tooth plate or rotating disk on the mandrel.Between pedestal and button and card key, also be equipped with spring.In Fig. 3, label 7 represents to reset the interlock plate, and 9a and 9b are respectively the square recesses that cooperates with the interlock plate that is positioned on time key 8a and the major key 8b, and there is tilting section 10a, 10b and recess 11a, the 11b of symmetry key 8a and 8b inboard.When major key 8b was pressed by corresponding key 3, square recess 96 did not just hinder interlock plate 4.Make it to move along direction perpendicular to paper, and cause mandrel to rotate, lock is opened, the interlock plate 7 that resets cooperates with tilting section 10b, recess 11b, make card key 9b be in illustrated and two kinds of stable states that be pressed, and this two states is changed, obviously, it is inoperative to the unlatching of lock to press long key 8a.The quantity of major key and time key and arrangement can be selected arbitrarily.
The advantages such as mechanical digital puzzle lock of the present invention has simple in structure, and security performance is good are the upper of the existing like product of improvement Good selection.
Claims (2)
1, a kind of mechanical digital puzzle lock comprises lock body and tapered end two parts, and lock body comprises dead bolt and the interior unlatching handle with mandrel interlock at least, the control section that tapered end comprises mandrel, rotates with the outer unlatching handle and the control mandrel of mandrel interlock.It is characterized in that, control section comprises: form interlock plate quadrature, that have the slot of band peripheral notches by major key, inferior key and reset key, the pedestal that there are a plurality of slits card key and interlock plate pass is installed, the interlock batten that resets, and the spring that the card key is used is installed.
