Abstract
The invention relates to a combined lock, in which a coded lock group and an auxiliary lock group are included. The coded lock group and the auxiliary lock group can separately and independently adjust the locking and unlocking status of a tongue piece component, the combined lock can be opened by users by utilizing the coded lock group under normal circumstances, and when the user forgets the cipher code, the combined lock can be opened by utilizing a spare key through the auxiliary lock group without damaging the combined lock.
Description
Technical field
The present invention is a kind of composite lock, refers in particular to two kinds of different cores of a kind of integration in single lockset, and can utilize the two cores composite lock of release respectively.
Background technology
Coded lock is general simple and easy lockset commonly used, it is the release or the state of locking that the character wheel that the user locks by rotational password changes core, then saved the necessity that the user carries key, and the convenience that increase is used, the modern needs setting code equally when using many article, for example teller machine, strongbox, PC encryption, access of ad hoc networks territory or the like, if all be set at identical password, then have the inclination the personage and crack wherein the article that one group of password can use all same password, lose its safety.
For the sake of security, the general practice can be set one group of independently password to every article, but also causes awkward puzzlement.With the password of electronization, for example teller machine, PC etc. when the user forgets setting code, can or reset by inquiry and obtain one group of password and come release; Otherwise if in a single day mechanical code lock forget password, then only can destroy this coded lock can release; Therefore, the user must keep the password of each mechanical code lock firmly in mind, could obtain release smoothly, quite inconvenience on using.
Summary of the invention
Because the shortcoming of aforementioned prior art the purpose of this invention is to provide a kind of composite lock, allow the user when forgetting Password, can be by key operated this composite lock, then the user can forget Password and keep under the integrality state of lockset and unblank.
Secondary objective of the present invention is to provide a kind of composite lock, allow the user after utilizing auxiliary key to unblank, find original password, so that memory cipher or revise password again then is provided with the corresponding number of looking for hole, and is provided with the corresponding number of looking for groove in the coded lock assembling in inner lock shell and bottom, then the user can utilize probe to run through bottom and inner lock shell, to seek the corresponding number of looking for groove, then can follow and find out original password, and then be able to again memory cipher or revise password.
For reaching above-mentioned goal of the invention, the technology used in the present invention means are a kind of composite lock of design, comprising:
One inner lock shell, it has a front end face and a rear end face, and inner lock shell central authorities run through and form an auxiliary lockhole, and the front end face indent of inner lock shell forms at least one group of password locked groove;
One lock bolt sleeve, it is located in the rear end face of inner lock shell;
One bottom, it is sheathed on outside inner lock shell and the lock bolt sleeve, the front end of bottom is an openend, form a cover plate with back-end closure on the rear end of bottom, the cover plate axis of centres has an extension rod to elongation moulding, extension rod is sheathed on outside the lock bolt sleeve and the lock bolt sleeve extends outside the end of extension rod, and the internal face of the openend of bottom directly concaves and forms at least one caulking groove;
One tongue piece assembly, it is located at the bottom rear end relatively and joins with the lock bolt sleeve, and the tongue piece assembly includes a tongue piece and a fixture, and tongue piece is sheathed and be fixed in outside the end of lock bolt sleeve, and fixture wears and is fixed in the end of lock bolt sleeve;
At least one coded lock group, it is located in the front end face of inner lock shell in the corresponding password locked groove;
One blocking plate, it is located in the front end face of inner lock shell, blocking plate top stretches out and forms a projection, projection runs through forming an at least one cipher lock hole and an auxiliary lockhole with respect to the caulking groove of bottom in the blocking plate, the cipher lock hole of blocking plate is sheathed on outside the corresponding coded lock group, when the coded lock group is when locking state, the caulking groove tabling of the projection of blocking plate and bottom, when the coded lock group was released state, the projection of blocking plate can break away from the caulking groove of bottom;
One auxiliary lock group, it is located in the auxiliary lockhole of inner lock shell and extends outside the auxiliary lockhole of blocking plate, and joins with the lock bolt sleeve, is then driven the lock bolt sleeve with respect to inner lock shell and bottom rotation when the auxiliary lock group is released state;
One loam cake, it is sheathed on outside the bottom, the rear end of loam cake is an openend, form a cover plate that front end is sealed on the front end of loam cake, run through in the cover plate and form at least one cipher lock hole, the cipher lock hole of loam cake is with respect to the cipher lock hole of blocking plate and be sheathed on outside the coded lock group, runs through forming an auxiliary lockhole in the cover plate, and the auxiliary lockhole of loam cake is with respect to the auxiliary lockhole of blocking plate and be sheathed on outside the auxiliary lock group.
Compared to prior art, the invention has the advantages that: when the user remembers password, the locking state that the coded lock group is untied in utilization reaches the purpose of unblanking, but when the user forgets Password, utilize auxiliary key with the release of auxiliary lock group, and can reach the purpose of release equally, therefore when the user forgets the password that sets, can under the prerequisite of keeping the composite lock overall integrity, unblank equally, so the present invention really has its practicality.
